DESCRIPTION

Glass with lid for drinking

The present invention relates to a plastic cup, which is suitable for a storage stool, with a removable sealing foil and a drinking lid, the lid for drinking having a raised peripheral edge, in which an opening is formed for to drink.

Coffee has been offered for many years to take in suitable glasses for it. This is usually hot coffee, although fine drinks are also offered in this way. The glasses were made before substantially of coated paper or cardboard and plastic caps are placed under pressure. Vessels of this type correspondingly have a thickened peripheral edge, which in the majority of cases is beaded, and the plastic caps adapted to them fit with correspondingly formed flanges behind this flanged edge.

The drinking glasses have, in the majority of cases, a raised peripheral edge in which an opening for drinking is formed. A glass of this type with a lid for drinking which is placed under pressure is described for example in US 2012/0292317. Also the document US 2012/125949 discloses a lid for drinking that fits under pressure with a removable cover sheet that covers the entire surface.

Glasses of this type with a lid for drinking are filled in gastronomic establishments and delivered to the final customer for immediate use.

To prevent the end customer from spilling the drink during transport, different types of plastic caps were developed, which can be partially opened to form an opening for drinking, and the part for quick opening can be turned back as a tongue to return to close. Of course, drinking caps of this type do not close the vessels tightly, although this does not represent any problem, since, as already mentioned above, the content is intended for immediate consumption. The manufacture of a lid of this type that can be closed again and that can be placed under pressure in a vessel is described in US 2004/0104503.

For the solution known for the coffee to be taken from the gastronomic establishments, they have been later, practically inspired by this solution, also solutions that are suitable for industrially manufactured storable beverages, in particular coffee fno. Also here is used a glass and a lid for drinking that can be fixed in it, simply placed under pressure. Since storage stability requires, however, an absolutely watertight container and the requirements of an aseptic package must also be met, it was no longer enough to just put a plastic lid on the vessel under pressure.

For this it was necessary to seal the glass completely. The sealed issue must be fixed on the peripheral edge of the vessel. In order to make a sealing of this type reasonably possible and also to increase the resistance of the vessel, plastic cups were therefore manufactured and their upper peripheral edge was flatly configured, so that an aluminum foil could be welded smoothly absolutely watertight. In the sealed vessel, a known plastic lid was placed under pressure on the aluminum foil.

However, this solution was not yet satisfactory. Although a perfectly transportable and stable container is obtained, for the user a solution of this type is problematic. In many cases, the user wishes to open the glass when walking or carry the glass completely closed in his car, to open it there. To do this, first you have to lift the lid, which can be done relatively unproblematically, but then you must break the welded or glued sheet with a removable lacquer. To do this you need both hands and if you make this opening when walking or in the car, there is a risk that, on the one hand, you do not keep the glass exactly on the horizontal and, if you also move, there is a relatively large risk that The drink found in it is spilled.

Here, document US-2010/0301109 is considered the closest state of the art. This discloses a plastic or paper cup with an external thread and a lid for drinking without sealing sheet with raised peripheral edge, in which an opening for drinking is formed and which has an internal thread. The glass is used to be filled at the place of sale with a hot or cold drink, so elements are not necessary to ensure integrity. The drinking lid of this known glass has a separate, movable closing part, which can close the opening for drinking in a sealed manner.

Therefore, the present invention has the objective of creating a suitable glass for a plastic storable end beverage with a removable sealing foil and a drinking lid according to the preamble of claim 1, in which the risk above is substantially reduced mentioned of the spill.

Storable end beverages of this type are in most cases sweetened to a relatively high degree. The possibility of sweetening a non-sweetened beverage by adding a sweetener or sugar is not provided. Naturally it is conceivable to paste sugar or sweetener packed on the wall of the glass or on the lid to drink. However, this is an unsatisfactory solution from the aesthetic point of view and

servings of sugar or sweetened portions of sweetener can easily be removed already in the refrigerated shelf. Therefore, another aspect of the present object of the invention is to offer a solution that allows the beverage to be subsequently sweetened and that aesthetically meets the requirements of the market. The aforementioned objective is achieved with a plastic cup for a storable beverage according to the preamble and the characterizing properties of claim 1. Other embodiments according to the invention of the object of the invention are indicated in the dependent claims and their meaning and operation will be described in the description set forth below with reference to the attached drawings.

An exemplary embodiment of the object of the invention that will be described below is represented in the drawing. They show:

a preferable form of a sealing sheet.

Figure 1 shows the glass with the lid for drinking in the assembled state as it reaches the shelves of the shops. The vessel is designated in conjunction with the reference sign 1 and the drinking lid screwed on it with 2.

The removable sealing sheet 3 is attached to the drinking lid. The thin glass 1, suitable for use with one hand, is made entirely of plastic.

It has a bottom 10, next to which the wall of the vessel 11 is arranged, which turns up into a thickened wall area 12, which then forms a diminished sealing edge 15. The bottom 10 is configured slightly bulged towards up in the center, to be placed safely. In the thickened wall zone 12 an outer thread 13 is formed. This thickened zone 12 is then converted into said reduced sealing edge 15. Below the thickened wall zone 12 a stop flange 14 is provided. This may have , as shown here, a peripheral clamping ring 17, oriented radially outward. This clamping ring 17 is used for handling in a filling installation and increases the shape stability of the vessel 1. In accordance with the invention, at least one point is provided with a positive adjustment means 16 on the stop flange , which in the present example is made in the form of a nerve 16 'radially oriented outward, whose meaning and effect will be described later.

A drinking lid 2 is screwed into the vessel 1. This drinking lid 2 has a cover surface 20, which is joined in a piece with a raised peripheral edge 21. On the outer side of the raised edge 21, which is configured with a U-shaped cross section and from which one arm extends downwards to the cover surface 20, the outer arm of the raised edge 21 is formed as a collar 22. This collar 22 has an inner thread 23, which cooperates with the thread outside 13 of the glass. The peripheral collar 22 of the drinking lid 2 extends further down, almost reaching the peripheral clamping ring 17 mentioned above to increase the shape stability and processability in the filling installation. From the outer arm of the raised edge 21 extends a so-called olive sealing 18, which sits against the inner side of the reduced sealing edge 15. The drinking lid is sized such that in the completely screwed state the reduced sealing edge 15 It fits between the sealing olive 18 and the peripheral collar 22 and sits with a minimum seat from below against the inner surface between the sealing olive 18 and the collar 22. The reduced area of the sealing edge 15 causes a greater tightening force specific and therefore a better seal. The drinking lid 2 therefore has two sealing points that cooperate with respect to the glass, that is, on the one hand, the sealing point that sits against the inner side of the glass by means of the sealing olive 18 and the reduced sealing edge 15 which acts upwards, which presses from below on the lid for drinking 2 and thus forms a second sealing point. Here it is noteworthy that the cover surface 20 is disposed strongly offset downwards from the raised peripheral edge 21. In principle, the cover surface 20 could be arranged in the same plane as the raised edge 21, although in this way a very large welding surface is formed, which is not recommended. Thanks to the cover surface 20 displaced downwards, the upper surface of the raised peripheral edge 21 only has to be weldable or the removable sealing sheet 3 only has to be solvable annularly.

The sealing sheet 3 is represented by itself in Figure 4. It is preferably an aluminum sheet coated on both sides with a plastic. While the plastic coating of the sealing sheet on the lower face, which is arranged towards the vessel 1, is a very thin coating that only serves to achieve a weldable coating, the upper plastic coating, which will be printed, can have a somewhat larger thickness. In addition, the lower coating, which is used for sealing, is made of PE-LD (low intensity polyethylene) or PE-LLD (linear low density polyethylene), while the upper coating is made of pE-HD (polyethylene) high density). In this way it is guaranteed that in the welding process the lower coating softens to the point that it establishes a sealing joint with the edge of the lid for drinking.

Especially preferably, the cover surface 20 is pulled down to such an extent that in the assembled state of the vessel 1 and of the drinking lid 2 it protrudes downward below the plane defined by the upper edge of the sealing edge 15. Thus a relatively large space results. For reasons of comfort, this serves as a space where the nose fits when drinking, and as will be described later, it can also serve as storage space.

The drinking lid 2 has two openings, which are diametrically opposed to each other and which are arranged on the flat surface defined by the raised edge 21. On the one hand, it is an opening for drinking 24 approximately oval and, on the other hand, a ventilation opening 25. The ventilation opening 25 serves to allow sufficient air to enter the drinking, which replaces the volume drunk of the beverage. The raised edge 21 will preferably have a widening 21 'in the area of the drinking opening 24. This widening means that, on the one hand, the drinking opening 24 can be configured sufficiently large and, on the other hand, a weld surface Large enough around the opening to drink.

As already mentioned above, a removable seal sheet 3 is attached to the drinking lid 2. To ensure the quality of the contents of the glass, it must be sealed tightly. Correspondingly, the raised edge 21 must have a flat annular welding surface 40 above. If the raised edge 21 was raised in the form of a beak in the area of the drinking opening 24, as is customary in many cases in drinking caps for drinks of this type, the removable sealing sheet 3 will not be arranged on a flat surface and welding will be very problematic.

Correspondingly, an aluminum foil with an HD-PE plastic foil is chosen as the sealing foil, that is, preferably a foil at least almost gas tight. For this, an EVOH sheet is suitable, for example. A sheet of this material is practically oxygen tight. Consequently, the risk of oxidation of the content is largely eliminated. EVOH (copolymer of ethylene and vimic alcohol) can be degraded to a large extent without being polluting for the environment and has produced good results, both in the food industry and in the area of medical technology. A sheet of this type or also an aluminum sheet coated with plastic is fixed here by welding.

The sealing sheet has a tongue 31 folded outwardly and downwardly passing by the edge 21, whereby the sealing sheet 3 can be removed. It may be advisable not to weld this tongue over the entire surface, so that one end is left Bottom free to catch the tongue. The length of the tongue can be chosen practically freely. If it only serves to remove the sealing sheet 3, it will end on the outer arm facing downward of the raised edge 21 of a U-shaped cross-section. However, if it is extended correspondingly, the tongue 31 can extend beyond the lower edge of the collar 22 and thus establish a union with the vessel 1. In this case, the tongue 31 represents at the same time an element to ensure integrity. This extended tongue is drawn in Figure 1 with a broken line and is identified with 31 '.

The tongue 31 is preferably configured with a width such that the entire widened edge area 21 'is covered as well as the part of the collar that is there. This is for hygienic purposes, to protect the area that the client touches with the lower lip to the to drink.

In addition to the priority objective of sealing the contents of the vessel, the removable sealing sheet 3 can also serve to seal a storage space 32, which results from the reduced cover surface 20 with respect to the upper raised edge 21. In the placed state of the lid for drinking 2 in the vessel 1, this cover surface can be practically shown at any depth. Depending on the depth of this storage space 32, any additional element can be accommodated therein. In particular, this storage space is suitable to accommodate additional elements of the group of sweeteners, sugar, pastries, chocolate or flavoring additives, such as caramel or cinnamon. Since the storage space has no connection with the contents of the vessel and this storage space is also practically sealed in a gas-tight manner with respect to this contents of the vessel, in case of adding a paste, for example, it can be renounced in principle to A special packaging of this paste. However, for hygienic reasons, the consumer will probably also try to find this paste specially packed in it. Naturally, this is also valid for the other additional elements.

In addition to the aforementioned possibilities of an element to guarantee integrity, which prevents unnoticed temporary elimination of the removable sealing sheet and at the same time by means of the correspondingly prolonged tongue 31 unscrewing of the drinking lid 2, naturally there is also the possibility that the drinking lid 2 has a non-destructible union with the glass, which serves as an element to ensure integrity. In accordance with the invention, both means for positive adjustment 16, 26 are provided in the lid for drinking 2 and in the vessel 1. According to the invention, the means of union for positive adjustment 16 in the stop flange 14 it is a concavity and the union means for positive adjustment 26 of the drinking lid 2 is an elastic tongue, which in the fully screwed state of the drinking lid fits into the concavity, whereby the two union means by positive adjustment 16 and 26 together form an insurance to prevent unscrewing as a guarantee element.

In contrast to this and not according to the invention, the vessel 1 can, for example, have a means of joining by positive adjustment 16 in the form of an elevation in the form of a sawtooth or, as shown here, in the form of a rib 16 '. Since in the cut-out drawing according to Figure 1 the cut passes through the rib 16 ', this looks the same as if the cut went through a saw-shaped elevation, whereby a special representation of This solution in the drawing. The lid for drinking 2 has in this case also a means of joining by positive adjustment. This means of joining by positive adjustment can be realized in the form of a part configured in a complementary manner in the collar 22. This means of union by positive adjustment 26 configured in a complementary way can be in practice an elevation, in which it fits by for example the elevation in the form of a sawtooth or, as can be seen in Figure 2, a groove 26 ', in which the corresponding rib 16' fits.

Preferably, a marginal window 27 is attached to the drinking lid 2 in the collar 22. The groove 26 'is made in this case directly next to this marginal window 27, so that between the window 27 and the groove 26' only remains a bar 28, which is destroyed when it is first opened. It is also possible a variant with a reverse unscrewing direction, in which the rib 16 'fits in the window 27 and the bar 28 is deformed by unscrewing in the direction of the groove, thus preventing an arm 29 attacking in the bar, which it is connected by a controlled break point 290 with the collar 22 and when unscrewed this controlled break point bridge 290 is destroyed. A large number of other forms of element realization are known from the patent literature to ensure the integrity of this kind. The collar 22 can naturally also be provided with a peripheral guarantee tape, this guarantee tape being able to fit below the stop flange 14. Thanks to the threaded joint between the drinking lid 2 and the vessel 1, the elements to guarantee the Integrity of this type can be fixed and removed again without problems, without the user spilling a portion of the content by doing so.

Finally, it is indicated that of course it is also possible, even if it does not correspond to the invention, to provide the glass with an inner thread and the lid for drinking 2 of an external thread instead of making an external thread in the glass and an internal thread in the drinking lid 2, as is the case in the example shown here, so that the drinking lid 2 fits into the vessel 1. Also in this case it is possible that a raised collar 22 extending towards the raised edge 21 is attached the exterior and this collar may be provided with corresponding sealing elements, which exert pressure on the outer wall of the vessel 1.
