Abstract

A portable and reusable drinking device that a user can carry passively on his or her person while taking part in a variety of activities. A garment accessory such as a belt pouch, a backpack or a jacket may be used to transport a flexible goatskin-like bag (101) provided with a drinking tube (111) and a pump (105) with an inlet tube (119). The various components are carried inside the garments or garment accessories, and the inlet tube (109) remains accessible to the user who may insert it into a beverage source such as a soft drink can and then use it very simply and conveniently to refill the drinking device with a beverage. The user actuates the pump (115) to pressurise the bag (101) then operates the mouth valve to let the liquid into his or her mouth. The mouth valve (113) is connected to the bag (101) via a drinking tube (111) that extends inside the lining of the garment or garment accessory and comes out through a lapel or other portion of the garment closest to the user's mouth. In another embodiment, a pump is incorporated into the bag to form a single element. In a further embodiment, a resilient member is joined to the inlet tube to enable said inlet tube to be sealingly fitted to virtually any kind of can or bottle which may then be safely carried by the user without fear of a leak. The pump (115) may then be used as often as required to maintain a constant pressure in the flexible bag (101).

Description

A REUSABLE BEVERAGE DEVICE

The invention relates generally to reusable beverage devices. More particularly, it relates to a pressurized beverage device that a person can carry with it in a convenient manner without carrying a bottle or box.

TECHNOLOGICAL BACKGROUND

In recent years we have seen the development of beverage devices that can be worn by one person for a multitude of activities. These activities include, cycling, hiking, camping, or daily activities such as driving a car. The oldest examples of these beverage devices include gourds and bottles, devices traditionally used by shepherds, travelers, etc. More recent examples of these devices include competitive items such as sports bottles , non-spillable coffee pots and the like.

Although convenient for these applications, many of these items require the person to carry a bulky object, such as a cup or other item. In addition, these devices generally require the person to focus their attention on the beverage device in order to drink. In other words, during activities such as cycling or driving the person must stop his activity to drink.

To remedy these problems, portable beverage devices have been developed allowing people to drink without interrupting their activities. These devices generally store liquid in a place, for example, in a tank mounted on a backpack or on the frame of a bicycle, and they are characterized by a pipe which leads the liquid from this place to a fixed place near from the person's mouth. Some of these devices may also include a source of pressurized beverage, that is, they have a flexible bag or suitcase which inflates elastically when the bag or flexible bag is filled with drink. This elasticity of the bag or bag provides a source of pressurized beverage that the person takes out through the beverage hose. A pinch actuated valve mechanism located near the end of the beverage hose can then be actuated by biting it to allow delivery of the beverage into the person's mouth.

Devices that deliver a pressurized drink are very useful, because they allow a person to drink without having to suck the drink through the drink pipe. Thus, whatever the location of the addition, for example in a backpack, the person has no significant effort to exert and does not turn away from his activity by sucking the liquid through a long drink pipe.

Such a device is described in U.S. Patent No. 5062591 to Runkel. This patent relates to a portable drink device in which the drink is stored under pressure in a bottle. This results in an expansion of the bottle in proportion to the volume of the fluid, a bit like the inflation of a balloon. To introduce the drink under pressure into the bottle, a type T mechanism is arranged in the drink circuit. The T-type mechanism includes a coupling to a bulb and a valve. To pressurize the bottle, the pear is filled with the drink, then it is pressed to force the drink into the bottle, via the T-type mechanism. The valve prevents the pressurized drink stored in the bottle and in the circuit. return to the pear.

Although pressurized devices have generally proven to be useful for dedicated purposes, some of these devices are difficult to recharge or pressurize. Thus, although some devices have a detachable pump of this type, the pump must normally be worn on the person's body to be usable; that is, it cannot be left at home. In addition, there is no suitable connection to a source of drink, for example example to a can of soda, or a tap of water. Another drawback of these devices is that the pressure is generally dependent on the volume of beverage in the container, therefore the pressure becomes very low when the container is almost empty. Since the above mentioned pumping mechanisms are normally constructed in such a way that they require the person to stop their activity or activities when the pressure drops, there is no existing means of refilling the bottle. provide constant beverage pressure, or continuously and automatically repressurize the can. Finally, another problem with these devices concerns the construction of the skin. In particular, the more liquid is stored in the bottle, the more the bottle expands, becoming bulky, a phenomenon due to its physical properties. This generally prevents the addition of the bag into a garment or other support, and obliges the person transporting the device to install the bag on the frame of a bicycle or to carry it in a rather bulky and bulky backpack .

There is therefore a real need in this area to create a beverage device which includes a convenient pumping system easily connectable to any source of beverage and which can be easily carried by a person. There is also a real need for a beverage device comprising both a pump and a beverage reservoir. Ideally, there is also a need for a device that can be easily incorporated into clothing, such as a vest, jacket, diving suit, or backpack, or other form of support. The present invention satisfies these needs and also provides other advantages.

SUMMARY OF THE INVENTION

The present invention provides a reusable and portable beverage device for one person. This device includes a pumping mechanism with two valves actuated by the person and an inlet pipe connectable to any source of beverage. So the person can carry a pressurized drink without the need to repeatedly attach or detach specific accessories. In addition, it allows the beverage delivery device to be integrated into a garment, such as a jacket, vest, diving suit, shoulder bag or the like.

In a first embodiment of the invention, an expandable addition serves as a reservoir for a drink and a pinch valve is used by the person to allow the pressurized drink to flow towards the lips of the person. In more detailed features of the invention, the pumping mechanism can be part of the integrated system, the elements of the mechanism can be inserted into a jacket or a vest for particular applications, such as hiking or diving. An inlet pipe comes out of the device or of the garment, so that a person wearing the device can fill the device without removing it from the pocket of the garment which supports it. Finally, according to particular features of the invention, a drink pipe can also be provided so as to come out of the garment, preferably out of the collar or the lapel of the jacket near the mouth of the person, so as to present a free end bringing the pinch valve close to the person's mouth.

In connection with other characteristics of the invention, a sealing member can be associated with the inlet pipe. This allows the person to purchase a store drink and carry it with them. For example, the reusable beverage device can be put in a small backpack that has a pocket for receiving a water tank. The inlet pipe can be fixed to the container, after opening it, and the pumping mechanism can then be used by the person to pressurize at will an elastic addition which retains the liquid under pressure. Thus, the pumping mechanism can be used, when the pressure becomes low, to repressurize the addition and provide a continuous source of pressurized drink. The pumping mechanism can be used in this way without forcing the person to stop his or her activities in order to maintain a certain constant pressure in the bottle.

According to another more detailed characteristic of the invention, the addition bottle or the beverage container is specially constructed to remain relatively thin despite its pressurization. Thus, the beverage device can be easily incorporated into clothing, so that an independent and bulky mechanism is no longer necessary for transporting the device.

The invention will be better understood with reference to the following detailed description, which should be read with reference to the accompanying drawings. The detailed description of a preferred embodiment, described below in order to allow the development and use of a specific application of the invention, is in no way intended to limit the value and the scope of the claims listed, but rather to serve as a demonstrative example.

The invention summarized above and defined by the listed claims can be better understood by reference to the following detailed description which itself must be read with reference to the corresponding drawings. This detailed description of a preferred pressurized beverage device, intended to allow the development and use of a specific application of the invention, is in no way intended to limit the claims listed, but rather to serve as a demonstrative example. The specific example imagined below is the preferred principle of a pressurized drink device constituting at all times a source of pressurized drink and pre-incorporated in a garment, luggage or any other support. Introduction to Main Elements and Applications

With reference to FIG. 1, the preferred pressurized drink device 101 can be seen including a source of drink 103, such as the illustrated soda can, a pump 105 and a reservoir 107. The pump 105 illustrated in FIG. 1 is a manually operated pump which is connected to the beverage source 103 via an inlet pipe 109 for collecting the liquid from the source. The reservoir 107 is made of an elastic material, preferably a food-grade rubber, which expands as the liquid is pushed inside the reservoir in question. At the outlet of the reservoir is the beverage pipe 111 which conveys the liquid from the reservoir to the mouth of the user. At the end of the beverage hose 111, at the level of the user's mouth, an oral valve 113 makes it possible to retain the pressurized liquid in the beverage hose 111, but which can be released at will by simple pinching or bite of the oral valve.

As a result, the preferred pressurized beverage device provides a mechanism to pressurize virtually any type of beverage and transport it to oneself. When the person concerned wishes to drink, it suffices to actuate the oral valve 113 so that the force tenfold by the elasticity of the wall of the beverage container is effective, propelling the beverage inside the beverage pipe 111 and there inside the user's mouth, going against the force of gravity. A person can thus get involved in any type of ordinary activity such as walking, driving, riding a bicycle or any other activity, and thus has no need to interrupt his or her activities to drink. On the contrary, by simple pressure on the oral valve 113, the person has immediate access to a pressurized drink without any distraction.

The preferred device presented consists of a pressurized beverage device which is integrated into a garment or into luggage such as a backpack or a belt bag. FIGS. 2-4 help to understand this principle of arrangement: FIG. 2 shows the integration of the pressurized drink device inside a jacket; FIG. 3 shows the integration of the pressurized drink device in a backpack or shoulder bag; and FIG. 4 shows the integration of the pressurized drink device into a backpack / belt bag combination.

FIGS. 2A and 2B illustrate a jacket 115 which incorporates the pressurized beverage device in its lining. A thin electric pump 117 is enclosed in the right pocket of the jacket 119 and is actuated alternately or continuously to pump the liquid from the source of the beverage. The source of beverage can be placed in the left pocket of the jacket 121, and is provided with a free end of an inlet pipe 109 inserted therein, to allow the electric pump 117 to pressurize the liquid and to propel it into the tank 107. The tank 107 is made of a food-grade rubber material and is installed at the rear location 123 of the jacket (FIG. 2B). The beverage pipe 111 conveys the liquid from the lining of the jacket 125 to the back of the jacket 127, where a specific housing has been arranged so as to resurface on the outside of the jacket, near the person's mouth. In this way, the person can wander or go about any occupation without the need to have to transport separately a source of drink such as a container of commercial drink. The inlet pipe 109 is used to connect at will a pump to a source of commercial beverage such as a soda can as mentioned before. At the same time, the wearer of the jacket can simply open a can of soda or other beverage container and use the pump to drain the beverage from the commercial container and propel it into the tank where it can be placed under pressure under pressure. inside of the jacket. One of the jacket model designs observed in particular is a model made of Neoprene, giving the jacket the characteristics of an underwater suit, so that the drink can be carried by an underwater diver.

FIG. 3A shows a shoulder bag 129 which contains a pressurized beverage device including the features of the present invention. In particular, the shoulder bag consists on the one hand of a pocket 131 which encloses the beverage tank and the pump, and on the other hand of a shoulder strap 133 in which is housed the beverage pipe 111 opening out to the upper end of the strap 135 in an area close to the mouth of the carrier of the bag. As can be seen in FIG. 3B, the pocket 131 comprises a lower compartment which contains both the pump 117 and the expandable reservoir 137 side by side, as well as the integrated inlet pipe 109 coming out slightly at the rear of the bag. The beverage pipe 111 originates in the lower part of the bag 139, from the reservoir, and runs along a lining of the bag to its upper end 135, near the mouth of the carrier of the bag. As with all the models mentioned here, the drink pipe 111 has a mouth valve 113 at its end which can be actuated at will by the carrier of the bag without having to open the bag or even remove it. to be able to drink. FIG. 4A shows another version of a support making it possible to transport a pressurized drink device relating to the present invention. In particular, this support is a backpack / bag-belt combination 141 which can alternatively be worn on the person's back or as a belt at the waist of this person. As seen in FIG. 4A, this backpack / belt bag combination 141 is longer than it is wide, and contains the reservoir and the pump inside a zippered pocket 143 which extends over the entire length of the bag combined. - backpack / belt bag. As seen in FIG. 4A, at both longitudinal ends, the backpack / bag-belt combination has an elastic strap in which the person can pass his arms respectively. In this way, the backpack / belt bag can be worn as a backpack by passing its left arm through a first strap 145 and its right arm through a second strap 147.

FIG. 4B represents a sectional view of the backpack / bag-belt combination 141, and illustrates in detail the fixing of the belt buckle mechanism which allows a selective connection between the first strap 149 and the second 151. In particular, the first strap 149 is fixed on a T-shaped portion 153 of the buckle, while the second strap 151 is fixed on a strap 155 which is specially adapted and sufficiently elastic to be able to snap into the T-shaped part provided for this purpose. To allow easy use as a belt bag, this model has a rather long beverage hose compared to the other models described above, so that the beverage hose can be stretched from the person's waist to their mouth. . Important, FIG. 4B shows the use of a preferential reservoir 107 relating to the present invention, which is relatively flat and which is clipped at its center 157 so that it cannot deform too much in thickness and that the combined bag-to-bag back / belt bag 141 thus retains a relatively narrow and homogeneous profile. The pressurized beverage device, its main applications thus presented, the preferential pump and reservoir mechanisms relating to the present invention will be described in more detail in the following chapter. Description of the Preferential Drink Device

Referring to FIG. 1, it can be seen that the preferred pump 105 comprises a preformed rubber bulb which receives the drink from the source 103 via the inlet pipe 109. When it is compressed manually, the pump is actuated to propel the drink into the outlet pipe 159, thereby forcing it to enter the tank 107. By using this pump 105, the user of this device can repeatedly compress the rubber bulb so as to repeatedly pressurize the tank 107, so that the tank 107 can thus keep the drink filled with it under constant pressure; when the pressure of the liquid decreases, the person recompresses the pear one or more times so as to repressurize the reservoir 107, in order to keep the drink contained in the reservoir under pressure.

Two variants of pumps are illustrated in FIGS. 5A and 5B. As shown in FIG. 5A, an electric pump 117 comprises a battery compartment 151 which can accommodate one or more batteries, an electric motor 167 operating on batteries to generate rotary energy, and a piston 163 which is actuated by the motor and integrated in the cylinder 166 of the pump. As can be seen in FIG. 5A, two ball valves 169 to respectively allow access to the pump cylinder via the inlet pipe, and the expulsion of fluid from the cylinder when the piston 163 is moved against the structure of the valve 169

(visible on the right side of FIG. 5A). In parallel, the pump can thus be used to automatically pressurize the reservoir 107 until a predetermined pressure is obtained adapted to the preferences of the user. A rubber sealing mechanism 171, such as a rubber cap, can also be used to fit over the top of a soda can 103 as shown in FIG. IA, for sealingly connecting the inlet tube 109 to the beverage source 103. At the same time, the beverage source can be carried in the pocket of the wearer's garment or in any other convenient location. For example, if the device is used in a car, the inlet pipe 109 can be connected to a source of beverage, such as a commercial container of water or soda, and the pump activated automatically and periodically to maintain a predetermined pressure in The reservoir.

FIG. 5B shows a variant of the pump mechanism model in which the pump and the tank are integrated in a single addition. As can be seen in FIG. 5B, the bottle 173 has a slightly more stretched shape and has a first pump end 175 and a second tank end 177. The bottle 173 has a circular opening in which a valve mechanism 179 is inserted during the process Manufacturing. The valve mechanism 179 can subsequently be welded to the rubber bag by a thermal welding process which makes the rubber wall of the bag adhere to the surface of the valve mechanism so as to completely isolate the pump end. 175 from the tank end 177. As can be seen in FIG. 5B, the valve mechanism 179 comprises two ball valves 181, each comprising a sealing ball 183 which bears against the seat 185 preformed in the valve mechanism. While the pump end 175 of the bottle 173 is manually pressed, the pressure of the beverage in the pump end is increased, deploying a force which acts against a spring located in the valve Release. This releases the ball from its seat and allows the expulsion of the fluid into the reservoir which will itself relax elastically. When the respective pressures of the pump and the bottle equalize, the force of the spring pushes the ball of the outlet valve again towards its seat, thus making the valve tight. When the pump end is released, the elastic force of the bottle creates suction in the pump end 175, and the higher pressure exerted in the inlet pipe 103 pushes the sealing ball 183 of the inlet ball valve 181 out of its seat 185, allowing the pump end 179 to fill with drink from the source. This two-ball valve structure is schematically identical to the valve structure of the pump shown in FIG. 1, and which can be seen in FIG. 6.

FIG. 12 illustrates yet another alternative pump mechanism called a rotary pump 301. The rotary pump 301 is in no point in contact with the beverage, and is designed to be able to connect or disconnect at will from the hose inlet, so that the rotary pump could be attached or detached at any time.

As can be seen in FIG. 12, the rotary pump comprises a grip handle 303 and a circular head 305 composed of two parts 307 and 309, shown open like the two parts of a shell, thus revealing the internal components of the pump head. The inlet pipe 311 which conveys the beverage contained in a zipper pocket 313 to a reservoir 315, is fitted into a peripheral groove 318 arranged in the first half 307 of the pump head. A rotary paddle wheel 317 throttles the inlet pipe 311, while the closing of the second half, valve-cover 309, of the pump head serves to trap the inlet pipe in the groove of the pump head. A locking pin 319 is used to lock the pump head in the closed position when the pump is in operation under selective manual control carried out by means of an on-off button 321. During operation, the pump 301 rotates the paddle wheel thus entraining the beverage in the inlet pipe towards the reservoir 315. For cleaning the various components of the pressurized beverage device, the inlet tube 311 can be disconnected from the pump 301 by opening the valve-cover 309 of the pump head and by disengaging the pipe from the groove and the paddle wheel.

As shown in FIG. 5B, the outlet pipe 111 from the tank is embedded in the mouth of the tank 187 via the valve mechanism 179, thus allowing the pressurized fluid to exit from the bottle 173 and to spread in the drink pipe 111 towards the valve mouth 113 at the free end of the drink tube.

FIG. 7 illustrates the preferred oral valve 113 10 in more detail. As can be seen in this figure, the mouth valve comprises a seat 193 formed by a protrusion in the beverage pipe 111, a pipe shutter 189, and a spring 191, which pushes the pipe shutter against the seat 193 . When the person bites the mouth valve 15, the pipe 189 is released from the seat shutter 193 allowing the pressurized liquid to flow into the person's mouth ^•.

III. The Preferential Tank

FIG. 8 is a schematic representation of the preferred reservoir which allows the beverage device of the present invention to be integrated into clothing. In particular, the reservoir in fact comprises four bottles 185 which are connected to each other in series via three tubes. 'interconnection 197. These wineskins 185 are each made up of two pieces 199 and 215 made of food-grade rubber and welded to all of their edges by a thermal process. In addition, the thermal process can also be applied to the central point 201 inside the container, so as to ensure that when pressurized the container retains a relatively flat shape while inflating elastically. In this way, the skin will expand in thickness but will retain a relatively thin profile, a bit like an air mattress made by inflating. As can be seen in FIG. 9, a pin system 203 can also be inserted through the rubber walls in their center to weld the two sheets of rubber for the purpose just described. In particular, this pin 203 can be inserted through the rubber which will subsequently be heated so as to weld to the pin, this to avoid any risk of leakage of the drink.

FIG. 10 proposes a variant of the preferred model of the further system which does not require any thermal welding process to connect the edges of the rubber walls together. Even better, this model of FIG. 10 uses one or more crimping systems which operate only by pressure to connect the two rubber walls together on their periphery and thus eliminate any risk of leakage. As can be seen in FIG. 10, the preferred crimping system comprises two frame elements 207 and 209 which close one over the other through the rubber, applying sufficient pressure to compress the walls of rubber against each other and prevent any leakage. through them. A crimping system 205 is also used in the central part of the two walls 211 and 213 to avoid excessive expansion of the film in thickness.

In particular, the operation of the crimping system is presented with reference to FIG. 11 which illustrates the crimping system 205 used in the central part of the bottle shown. This system comprises a female part 207 and a male part 209, which fit perfectly into one another to clamp between them the two rubber walls 211 and 213, in their middle. In particular, each of these systems consists of a block of rectangular shape, the female part 207 of which has a longitudinal groove chamfered inwards, while the male part 205 has a rib chamfered towards the outside, the shape of which is perfectly adapted to the dimensions of the groove. To assemble these two parts, the male parts 209 and female parts 207 are pushed and brought into contact with the opposite faces of the rubber sheets at the precise location where the groove 215 and the rib 217 are aligned, but do not yet overlap. The male 209 and female 207 parts are then slid relative to each other, while embedding the rib 217 and the intermediate rubber in the groove 215. The adjustment of the male and female parts then continues until that they reach a position where they both overlap one another, so that the two sheets of rubber 211 and 213 are riveted in their central part. The two frame elements are each generally U-shaped, and are adjusted by compression on the periphery of the rubber walls.

FIG. 13 shows yet another model of reusable drink device comprising an extendable addition 250 • which receives, via a drink pipe connected to a pump (not shown), a pressurized drink, said pump being one different types of pumps described above; Said addition can expand in proportion to the volume of the fluid entering under pressure, so as to develop a force for expelling the drink which is propelled towards the drinker through a drink tube 251 comprising an oral valve 252 actuable by the drinker for collect the pressurized drink in his mouth.

The bottle 250 consists of a single hollow chamber 253, flat and elastic, provided with a neck which constitutes the beverage pipe 251. The material used to make this addition could for example be a food grade rubber. The beverage pipe 251 is equipped with an oral valve 252 which, in this model, comprises a collar 254 molded in one piece with the neck and provided, in its central part, with a small slot 255. The oral valve 252 also allows connection to the pump outlet pipe when the pressurized beverage is propelled into chamber 253. lo

As can be seen in FIG. 13, the neck which constitutes the drink pipe 251 is retractable in the chamber 253 as illustrated in dotted lines. In addition, the extendable skin 250 is equipped with a hinged cover 256 which can close the chamber 253 when the neck has returned to the chamber. More so, to thermally insulate the chamber 253 and also to facilitate handling, the manufacturing includes a double wall 257 with air compartment 258. The said double wall 257 constitutes a rather rigid frame which allows the extendable skin maintain a relatively flat shape even when pressurized

To further improve the grip of the extendable skin 250, the capacity of the chamber of which is approximately one third of a liter, a small handle 259 can be added, as shown in dotted lines.

Having thus described a model of the invention by way of example, it is obvious that all the evolutions, modifications, and improvements which could come to mind of the most talented, although not specifically described or even mentioned above, n are no less implicit and intrinsic in the spirit and scope of the invention presented here. Consequently, the previous argument is intended only to be illustrative; the invention being limited and defined only by the following claims and equivalent thereto.
