Description

The invention relates to a drinking vessel, the top of which is open to form a drinking opening and is surrounded by an opening edge to be attached to the lips, with a drinking vessel lid which can be placed on the opening edge and which has a closable opening on its lid wall covering the open top of the actual drinking vessel.

It is known to use such drinking vessels, in particular drinking cups in self-service restaurants, the guest or user taking over the drinking vessel filled with the beverage at a counter or other dispensing point and carrying it to its place.

In order to avoid the spilling of drink over the opening edge of the drinking vessel, it has often been used to use oversized drinking vessels or temporarily put a lid on the filled drinking vessel, which the user has to remove before drinking. However, it is also known from US Pat. No. 3,146,842.

to provide a drinking vessel with such a lid, which has a valve-like opening. A lid formed with such a drinking valve can prevent the spillover of drink during transport of the filled drinking vessel, but not the leakage of drink, so that drink that seeps through in the area of the lid opening gives rise to contamination. Above all, the lid known from US Pat. No. 4,186,842, equipped with a drinking valve, cannot offer a gas-tight closure. Such a gas-tight closure is important, however, if, for example, carbonated drinks are to be filled into drinking vessels some time before consumption.

The object of the invention is therefore to provide a drinking vessel, the size of which can be fully used for filling the beverage and yet offers security against the spilling of the beverage over the opening edge when transporting the filled drinking vessel and tight closure of the filled drinking vessel. In addition to drinking by conventionally placing its opening edge on the lips, the drinking vessel should also be particularly suitable for using a drinking straw.

According to the invention, this object is achieved in that the opening in the cover wall is designed as an insertion opening for a drinking straw with at least one closure flap on its peripheral edge which can be closed by means of the elasticity of the cover wall, this insertion opening together with its closure flap being made by incisions in the form of die Cover wall is only partially formed penetrating notches in the cover wall.

The drinking vessel lid that can be placed on the opening edge of the drinking vessel is an additional element. But it can be mass-produced with much less material and much cheaper to produce than the additional costs for an oversized drinking vessel. Otherwise, it is up to the user whether he wants to close the filled drinking vessel with a drinking vessel lid. Furthermore, the drinking vessel lid offers the possibility of using a drinking straw without the need to remove the once-placed drinking vessel lid from the drinking vessel. The drinking vessel lid offers a complete, tight seal of the filled drinking vessel as long as no drinking straw is used. But even after inserting a drinking straw, the filled drinking vessel is still sufficiently securely sealed in practice. The user can therefore either insert the drinking straw into the drinking vessel lid placed on the filled drinking vessel to take it away.

In one embodiment of the invention, four closing flaps are formed on an insertion opening for a drinking straw by two notch-shaped incisions intersecting in the middle of the insertion opening. In another embodiment of the invention, two closing flaps are pre-formed on the insertion opening in that a T-shaped arrangement of two notches is provided in the cover wall.

Finally, in a further embodiment of the invention, only one closing flap is provided for the insertion opening and is formed by two notch-shaped incisions which meet in a V-shape at one corner of the three triangular insertion opening.

Special locking security for the drinking vessel is made possible with the drinking vessel lid when the actual drinking vessel is flanged from an opening edge to a curved lip edge and the drinking vessel lid is designed as a slip lid, which has a snap-in rim on its circumference that fits over the lip edge. This makes the drinking vessel lid very easy and simple to open

Snap on the opening edge of the filled drinking vessel. This secure seat of the drinking vessel lid on the opening edge of the drinking vessel is easily removable if desired, especially if the user wishes to remove the drinking vessel lid before drinking.

In order to ensure hygienic storage of the drinking vessel lids before use and while they are ready for use, the drinking vessel lid can have an annular stacking device within a peripheral edge, which is designed with a rounded stacking ring and rounded edges to pull the bottom drinking vessel lid out of a stack laterally allow. The drinking vessel lids can then be kept ready in a covered stack or as a stack in a dispenser. The user then only touches the lid that he removes from the stack.

For applications of the invention, in which filled drinking vessels are to be closed with a lid and kept ready for sale, the drinking vessel lid in the lid wall can have a central, trough-shaped recess into which the drinking vessel with its lower edge can be inserted, the insertion opening for the drinking straw and its closing flap, notch-shaped incisions are made on the bottom of this trough-shaped recess. It is then possible to stack filled drinking vessels sealed with such drinking vessel lids on top of one another and to have them ready for the sale of the bottled beverages.

Embodiments of the invention are explained in more detail below with reference to the drawing. Show it:

FIG. 1 shows a filled drinking vessel, closed with a drinking vessel lid, with a drinking straw inserted, partially in a side view and partially in an axial section;

FIG. 2 shows a top view of a drinking vessel lid to be placed on a drinking vessel according to FIG. 1;

Figure 3 shows the detail 3 of Figure 2 for a modified drinking vessel lid;

Figure 4 shows the detail 3 of Figure 2 for a third embodiment of the drinking vessel lid;

5 shows the one edge region of two drinking vessel lids stacked one on top of the other and

FIG. 6 shows the edge area 6 according to FIG. 1 of a further embodiment of the drinking vessel lid placed on a filled drinking vessel with another drinking vessel stacked thereon.

In the example in FIG. 1, a cup-shaped, filled drinking vessel 10 is closed with a drinking vessel lid 11, into which a drinking straw 12 is inserted. The drinking vessel 10 is formed at its opening edge with a curved lip edge 13 which extends all around and over which a latching edge 14 which is formed on the circumference of the drinking vessel lid 11 and which is designed as a slip lid is inserted. By means of this locking edge 14, in particular by means of the locking lugs 15 which are formed on it, the drinking vessel decoration is

kel 11 held securely on the opening edge of the drinking vessel 10.

Within its circumference or its latching edge 14, the drinking vessel lid has an annular stacking device 16, which serves to stack the drinking vessel lid 11, as shown in FIG. 5. This ring-shaped stacking device 16 has a rounded stacking ring 17 and rounded edges 18. This configuration allows the bottom drinking vessel lid 11 of a stack to be pulled out of the stack laterally.

The actual cover wall 19 is arranged within the stacking device 16, which is essentially flat and, in the examples according to FIGS. 1 to 5, lies in the plane of the upper side of the latching edge 14.

In the example of FIG. 6, an annular rib 20, which projects up to the level of the upper edge of the locking ring 14, is formed in the cover wall 19 within the stacking device 16, while the central part of the cover wall 19 as a central, trough-shaped depression 21 is trained. The lower edge region 22 of the drinking vessel 10 fits into this trough-shaped depression 21, so that drinking vessels 10 closed with drinking vessel lids 11 can be stacked one above the other in the manner shown in FIG.

In the middle part of the cover wall 19, as shown in FIGS. 2 to 4, an insertion opening 23 (shown in dashed lines) for a drinking straw 12 is formed. This insertion opening 23 is normally closed by one or more closing flaps 24.

In the example in FIG. 2, four closing flaps 24 are formed by a pair of incisions 25 intersecting in the middle of the insertion opening 23. In the example in FIG. 3, two closing flaps 24 are formed by cuts 26 which meet in a T-shape. Finally, FIG. 4 shows the possibility of providing the triangular insertion opening 23 with a single closing flap 24 which is formed by two incisions 27 which meet in a V-shape in one corner of the insertion opening 23.

The incisions 25, 26, 27 are formed as notches which only partially penetrate the cover wall 19 and which allow the cover wall 19 to be cut easily and completely by means of the drinking straw 12.

The insertion opening 23 with the closing flaps 24 or incisions 25, 26, 27 forming these two elements can also be provided in the example in FIG. 6, namely there at the bottom of the trough-shaped recess 21.

In the embodiment according to FIGS. 1 to 5, filled drinking vessels 10 closed with lids 11 can also be placed one above the other, but the stacking of filled drinking vessels 10 and lidded with lids 11 according to FIG becomes.
