Title: Beverage can

description

The invention relates to a beverage can after

Preamble of claim 1.

Known from the market are beverage cans, which comprise a container in which a filling consisting of a drinkable liquid is present. The container is usually made of aluminum and can be opened by pulling or pressing a tab. The filling often consists of a carbonated liquid. After opening the container, the liquid is thickened of the container to a gravitational

Leaking brought out of the container.

The object of the present invention is to provide a

To create beverage can, which delivers the liquid regardless of gravity to a user. In addition, the fun when using the beverage can to be increased. This task is accomplished by a beverage can with the

Characteristics of claim 1 solved. advantageous

Further developments of the invention are specified in subclaims. In addition, the invention features essential features in the following description and in the accompanying drawings. These features may be essential to the invention both alone and in very different combinations.

The beverage can according to the invention is characterized in that it acts on the filling

Compressor, a dispensing valve and a coupled with the dispensing valve spray head has. In this way it is possible that by depressing the spray head, the discharge valve is opened, so that the drinkable liquid is discharged from the spray head. By releasing the spray head, the dispensing valve is closed, thereby stopping the dispensing of the drinkable liquid. The beverage can according to the invention thus operates similar to a conventional spray can, as they are for example in

Hairsprays or defense sprays is eingesztzt. As long as the user depresses the spray head, the drinkable liquid is dispensed from the spray head. Only when the user no longer depresses the spray head, the delivery of the drinkable liquid is stopped. The user can thus determine even the amount of drinkable liquid to be removed from the beverage can.

It is the removal of the drinkable liquid

regardless of gravity. The charge must therefore not be triggered by the fact that the beverage can is brought into a certain position. This makes the removal of the drinkable liquid much easier, and it allows use of the beverage can according to the invention

for example, while driving, since the

User does not need to tilt his / her head back to remove the drinkable liquid.

In addition, the use of the beverage can according to the invention makes fun, especially at parties or similar events, since on the one hand, the removal of the drinkable liquid from the beverage can easily

Depressing the spray head can be forced, and on the other hand, the removal of the drinkable liquid from the beverage can only be stopped by letting go of the spray head.

A first development of the beverage can according to the invention is characterized in that the Pressurization a gas volume, in particular a standing under an overpressure

Nitrogen or carbon dioxide or air volume. Such a gas volume is environmentally friendly,

suitable for foodstuffs, storable and light

recoverable. It is conceivable to accommodate the gas volume in a space separate from the drinkable liquid by a membrane, for example in a membrane bubble closed by a stretchable membrane. Alternatively or additionally, it is conceivable that the

 Pressurization device comprises a movable wall which defines a space in which the drinkable liquid is housed, and by a

Spring device is acted upon.

In a further development, it is proposed that the drinkable liquid is received in a bag, which is fluid-tightly connected to the dispensing valve, and that the gas volume between the bag and a wall of the container is formed. In this way, the beverage can be used in any position, for example, overhead. This principle is also called "bag in can".

It is also proposed that the spray head a

Has discharge opening which is shaped so that the

 Liquid is discharged as an un-atomized liquid jet. This can on the one hand a larger

On the other hand, the taste experience is improved by the user. It is also advantageous if the spray head is firmly connected at least indirectly to the container. "At least indirect" means that the spray head need not be attached directly to the container, but over other elements, which in turn are connected to the container, thus ensuring a one-time use of the spray head, whereby the hygiene in connection with the use of beverage can according to the invention In addition, the robustness of the beverage can according to the invention is improved, but the solid compound should

be advantageously at least once solvable to the disposal of the beverage can usually from

Plastic spray head to be separated from the usually made of aluminum beverage can.

It is also particularly advantageous if the beverage can according to the invention comprises a housing and the container

interchangeable housed in the housing. A similar embodiment, for example, from the market on the market defense sprayers RSG-4 and RSG-6

Applicant, which are filled with a mucous membrane-irritating agent for the defense of animals and persons known. In this way, the container is in front

Damage protected, and it can be a visual

appealing outer shell can be created for any type of container.

In this context, it is also proposed that the housing has a spring-loaded pivotable cover which is against the spring force by a user can be opened for an actuation of the spray head. In this way, an accidental operation of the spray head in the storage of the beverage can

For example, in a purse or in a

Trouser pocket prevented.

Hereinafter, embodiments of the invention will be explained with reference to the accompanying drawings. In the drawing show:

Functionally equivalent elements and regions bear the same reference numerals in the figures.

A beverage can carries in the figures in total

 Reference numeral 10. It comprises a cylindrical container 12, the one present by a horizontal

Hatching drawn filling 14 contains, which consists of a drinkable liquid. As a drinkable liquid is, for example, a carbonated lemonade or a juice in question, but there are also alcoholic

Beverages such as beer, wine, brandy and alcoholic mixed drinks in question. The beverage can 10 further comprises a

 Pressurization device 16, which in the present case a standing under an overpressure and dotted drawn gas volume 18 comprises. In the present case, the gas of the gas volume is nitrogen. But it can also be carbonic acid or another environmentally friendly and food-safe gas, in particular air. In the illustrated very simple embodiment, the

Pressurization device 16 formed by the gas volume 18, which is bounded directly by the inner wall of the container 12 and the filling 14. In a somewhat more complex embodiment, not shown, the

Pressurizing means a present in the container bladder of an extremely stretchable membrane, which is filled with the gas volume. This bladder can, for example, in the upper area of the in FIG

Container 12, where in Figure 1, the gas volume 18th

is drawn, can be arranged. In a further embodiment not shown, the

 Pressurizing device a movable wall which defines the space in which the filling is present

limited, and which is acted upon by a spring.

The beverage can 10 further includes a dispensing valve 20 arranged in the container 12 at its upper end in FIG. 1. An inlet of the dispensing valve 20 is via a dip tube 22 is connected to a lower portion of the container 12 in Figure 1. An outlet of the dispensing valve 20 is connected to a tubular valve nipple 24. In turn, a spray head 26 is placed firmly on this, whereby the spray head 26 is ultimately coupled to the dispensing valve 20. The valve nipple 24 is pressed by a not shown spring of the dispensing valve 20 in Figure 1 upwards. It can be pressed against the force of the said not shown spring in Figure 1 down, whereby the dispensing valve 20 opens and the dip tube 22 with the

Valve nipple 24 is connected.

The spray head 26 has a discharge opening 28, which is shaped so that a liquid emerging from the discharge opening 28 as an un-atomized liquid jet

 (Reference numeral 30 in Figure 1) is discharged. For this purpose, the discharge opening 28 via a in the spray head 26th

extending, but not shown in Figure 1 channel with the valve nipple 24.

If the filling 14 contained in the beverage can 10 are removed (at least in part), the spray head 26 is pressed towards the container 12 by a user in accordance with the double arrow 32. This will also the

Valve nipple 24 corresponding to the double arrow 34 in the

Dispensing valve 20 is pressed in, whereby this opens. When the dispensing valve 20 is open, the dip tube 22 is connected to the valve nipple 24, as already mentioned above. Due to the pressurizing device 16 is present in the container 12 filling 14, consisting of the drinkable liquid, under pressure. Via the dip tube 22, the dispensing valve 20, the valve nipple 24, the present in the spray head 26 channel and the discharge port 28 now escapes the drinkable liquid 14 from the container 12 in the form of the liquid jet 30th

The drinkable liquid 14 is as long from the

Container 12 is delivered as the user holds the spray head 26 pressed. If the user lets go of the spray head 26, this is by the spring, not shown

Dispensing valve 20 via the valve nipple 24 (double arrow 34) again moved away from the container 12 (double arrow 32). By the movement of the valve nipple 24 out of the dispensing valve 20 out this is closed, whereby the fluid connection between the dip tube 22 and the valve nipple 24th

interrupted and the delivery of the drinkable liquid 14 is stopped. It is understood that the delivery of the

Liquid 14 can be made via the discharge opening 28, for example directly into the mouth of the user,

of course but also for example in one

Container can be made, for example, in a drinking glass or the like.

The embodiment shown in Figure 2 of a beverage can 10 differs from that of Figure 1 in that the beverage can 10 of Figure 2 in addition

cylindrical housing 36 includes, and that the container 12 is removably received in the housing 36 and reversibly secured by means not shown. On the right in Figure 2 side, the housing 36 has in the region of his upper edge via an opening 38 through which the

Dispensing opening 28 of the spray head 26 can protrude outward.

In addition, the housing 36 has a

spring-loaded pivotable cover 40, wherein a hinge 42, with which the lid 40 is pivotally mounted, is disposed above the opening 38 for the discharge opening 28. On the upper left side of the housing 36 in FIG. 2, there is an opening 44 through which a user can intervene, for example with his thumb. He can then with the thumb, the cover 40 against the spring force in Figure 2 pivot upward in a position which is shown in Figure 2 by a dashed line. Now the user can press with his thumb on the spray head 26 to trigger a dispensing of the potable liquid 14 from the container 12 through the discharge opening 28.

Yet another embodiment is shown in FIG 3. This is the so-called "bag in can" principle

realized. This is understood to mean that the filling 14 with the drinkable liquid is contained in a bag 46 which is connected in a fluid-tight manner to the dispensing valve 20 via a short connection nipple 22. The bag 46 may for example be made of aluminum, but it is also possible that it consists of a plastic material. The material from which the bag 46 is made, is flexible in any case, if necessary, also stretchable. It is also possible that on the connection nipple 22

is completely dispensed with and the bag 46 is instead attached directly to the dispensing valve 20. The space which is formed between the bag 46 and a wall (without reference numeral) of the container 12 is filled with the pressurized gas volume 18, which forms the pressurizing device 16 so far. The advantage of this embodiment is that a discharge of the filling 14 in any position of the container 12 is possible, that is, for example, even if this is held upside down, the spray head 26 thus below and the container 12 are above.

To produce the embodiment shown in Figure 3, the procedure is as follows. First of all, before that

Closing the container 12, the bag 46 is fluid-tightly connected to the connection nipple 22. In this state, the bag 46 is unfilled, so contains neither the filling 14 nor a gas, such as air. The walls of the bag 46 are therefore adjacent to each other. Now the container 12 is closed, this being done under pressure,

for example, such that the gas volume 18, which fills almost the entire interior of the container 12 in this state, under a pressure of about 3-5 bar.

Now, the filling 14 is introduced into the bag 46 by the valve nipple 24 is pressed to the dispensing valve 20 and this is thereby opened. About the valve nipple 24 and the open dispensing valve 20 so the filling 14 in the

Bag 46 introduced until it is filled in the desired manner, for example, bulging, as shown in Figure 3. As a result, the gas volume 18, which is present between the bag 46 and the wall of the container 12, compressed, whereby the pressure on increased a final pressure of about 7 bar. It is understood that the indicated pressure values are merely exemplary and, of course, other pressures are also conceivable. In particular, in the embodiment shown in Figure 3, it is possible that after emptying of the filling 14, the beverage can 10 is refilled again in the manner just described. Unlike the

Namely, the gas volume 18 can not escape even with complete emptying of the filling 14, so that after a new filling of the bag 46 with a filling 14 from a drinkable

Fluid can be released immediately under pressure again.
