Definitions
- the invention relates to a drinking attachment for a beverage can, comprising an attachment body which forms a circular attachment opening on the can side for placing on a beverage can, which forms a drinking opening at the opposite end and which has a transitional section between the attachment opening and the drinking opening with a flow cross section that tapers towards the drinking opening.
- the invention also relates to a beverage can with a drinking attachment.
- a drinking attachment of the type mentioned is described, for example, in DE 9317174 U1.
- Beverage cans are not only a widespread commercial packaging for beverages, they also serve as drinking vessels. They are mainly used for carbonated drinks such as e.g. B. Soft drinks used and means
- Drinking caps have been known for a long time in a wide variety of forms and enable a user on the one hand to consume a liquid contained in a drinking vessel provided with such a drinking cap, usually by gently sucking it on.
- they prevent the liquid from leaking or at least spilling out of the drinking vessel.
- they usually have a lid that closes the drinking opening of the drinking attachment or some other closing mechanism that can be operated manually.
- Such drinking caps have proven themselves in particular for drinking bottles in which the drinking cap can be screwed onto the thread formed on the drinking vessel.
- drinking caps have hardly been used to date. Furthermore, such drinking caps do not solve the problem of the beverage being heated.
- the present invention therefore aims to further develop a drinking attachment in such a way that the beverage remains fresh and palatable for a longer period of time after a beverage can has been opened.
- the escape of carbonic acid should be reduced and the heating of the beverage should be delayed.
- the invention consists in a drinking attachment for beverage cans of the type mentioned essentially in that in the area of the drinking opening, a when the beverage is poured, a spout valve that opens automatically is arranged and that cooling ribs are provided in the transition section upstream of the spout valve.
- the spout valve ensures that the drinking opening of the drinking attachment remains open when the person is standing or is closed in the vertical position, so that on the one hand no foreign objects can get into the beverage can and on the other hand less carbonic acid is released into the environment.
- the pouring valve is designed in such a way that it opens automatically when pouring out. This increases user comfort, since manual actuation of a closure generally requires two-handed operation.
- the spout valve opens automatically by tilting the beverage can when the drinking cap is placed on the mouth. Conversely, the spout valve is automatically closed again after drinking as soon as the beverage can is standing or standing again. vertical state is .
- a manually operable closure on the other hand, there is the possibility that the user forgets to operate the closure, so that carbonic acid escapes unintentionally.
- a double cooling function is realized by the cooling ribs provided according to the invention. Due to the fact that the cooling ribs are arranged upstream of the spout valve in the drinking attachment, when the spout valve is closed, they are in open connection with the beverage in the open beverage can. The interior of the opened beverage can, together with the beverage it contains, and the cooling fins are thus connected to one another by a common volume of air.
- the first cooling function is hereby generated by the fact that a rising, heated air reaches the cooling fins, on which the air is cooled, whereupon the cooled air flows into the interior of the Beverage can sinks down and keeps the drink cool there.
- the cooling ribs can serve as passive cooling elements when the drinking attachment has been cooled before use, for example by placing it in a refrigerator or freezer.
- the second cooling function is realized during the drinking process.
- the beverage is poured out, the liquid flows out of the beverage can over the cooling fins and is cooled there by conduction before it reaches the person's mouth through the drinking opening.
- the spout valve is designed as a ball valve, which comprises a ball arranged in a ball guide, which in the closed state of the spout valve rests sealingly on an annular valve seat.
- the sphere can be made of a material with a higher specific weight than water, for example glass or polymethyl methacrylate (Plexiglas).
- the design of the spout valve as a ball valve represents a structurally simple solution to close the valve in the vertical state of the beverage can solely by the effect of gravity or. to be kept closed by the ball resting on the underlying valve seat.
- the ball rolls away from its valve seat and thereby opens the spout valve. To prevent the ball from making uncontrolled movements or even getting lost, it is held in a ball guide.
- the ball guide is preferably formed by a cage.
- the cage forms a space in which the ball is enclosed and includes numerous openings through which the beverage coming from the beverage can can flow towards the drinking opening.
- the cooling ribs are designed as ribs that project radially into the flow cross section and are distributed over the entire inner circumference of the attachment body.
- a channel is formed between adjacent ribs, which extends in the pouring direction, d. H . from the tower opening towards the drinking opening. Due to the ribs, a large surface area is made available which is contacted by the liquid flowing through, resulting in improved cooling of the beverage.
- the cooling ribs can preferably have a radial extension that increases in the direction of the drinking opening, resulting in a flow cross section that narrows in the direction of the pouring valve, which leads the beverage to the drinking opening in an advantageous manner in terms of flow.
- the cooling fins are preferably made of a material with a high specific heat capacity.
- the cooling fins are preferably made of a plastic with latent heat storage properties.
- the cooling fins can be designed as hollow bodies and equipped with a latent heat storage or Phase change material or with a cooling liquid such.
- a preferred embodiment of the drinking attachment provides that the attachment body is designed as a plastic part, into which an insert part having the ball guide and an insert part having the cooling ribs Insert are used. This makes it possible to manufacture the insert parts from a different material than the attachment body.
- the valve seat can be designed in one piece with the attachment body.
- the attachment body has a circumferential locking groove in the area of the attachment opening, which can be locked on a circumferential bead of a beverage can.
- FIG. 1 a drinking attachment placed on a beverage can, in longitudinal section, FIG.
- FIG. 3 the cage of the valve ball and FIG. 4 the heatsink with cooling fins .
- the drinking attachment 1 shown in FIG. 1 comprises an attachment body 2 which has a circular attachment opening 3 at its lower end and a circular drinking opening 4 at its upper end.
- a locking groove 5 is formed on the inner circumference of the attachment body 2 , with which the drinking attachment 1 is locked with a can bead 6 of a cylindrical beverage can 7 .
- the outer contour of the attachment body 1 tapers in a transitional section 8 located between the attachment opening 3 and the drinking opening 4 and forms a likewise tapering flow cross section on the inside.
- a spout valve 9 designed as a ball valve which comprises a ball 11 held movably in a cage 10, which rests sealingly on an annular valve seat 12 when the spout valve 9 is in the closed state.
- the annular valve seat 12 is formed in one piece on the attachment body 2 .
- a heat sink 13 with cooling ribs 14 (FIG. 4) is accommodated in the attachment body 2 in the transition section 8 .
- the cooling ribs 14 are preferably designed in the form of disks and extend inward in the radial direction from the cooling body 13 .
- a channel 16 (FIG. 4) through which the drink can flow is formed between adjacent cooling fins 14 .
- Fig. 3 shows the cage 10 of the ball valve 9 in a perspective partial section, whereby it can be seen that the cage 10 has a cylindrical jacket 15 from which radial webs 17 distributed in the circumferential direction extend inwards, which delimit a space for the ball 11 .
- the webs 17 are curved on their inside and are brought together in the center, so that the space accommodating the ball 9 has a dome-like roof.
- Fig. 4 shows the heat sink 13 , which has an outer contour that follows the inner contour of the attachment body 2 , so that the heat sink 13 can be accommodated with a precise fit in the transition section 8 in the attachment body 2 . Furthermore, the cooling fins 14 can be seen, which each form channels 16 between them.
