Description

Drinking cup lid with drinking passage

The invention relates to a drinking cup cover with at least one drinking passage and a lid edge for sealing insertion into the drinking opening of a cup.

Drinking cups are available for hot and cold drinks, for multiple use and for disposal, and accordingly made of various materials such as ceramic, glass, metal, plastic, with waterproof or water-repellent coating or impregnated paperboard and combinations thereof. As a cup in the widest sense according to the invention are understood vessels that can grab and lift up according to size and weight with one hand as intended and having an opening (drinking opening) with a shape of its edge, which allows a drip-free drinking, and a standing surface or Stand device that allows the placement of the cup on a horizontal plane, so that then liquid still remains in the cup. In particular, however, understood as a cup in the narrower sense of the invention, vessels (as intended parked on a horizontal plane) at least in the region of the opening about a vertical axis are rotationally symmetric and at least in the region of the opening at least with its inner wall from the edge axially downwardly tapered.

For such and in particular the intended for disposal cups are known to lid, which can be used to prevent the drinking liquid to spill, cover the drinking opening. Such lids, and also the invention, are particularly intended to be kept ready in restaurants, where drinks (also) are served for consumption on the way. Such covers, and also the inventive, are preferably made of plastic such as recyclable polypropylene.

The known lids usually have a snap-on structure which is suitable for snappingly encompassing an edge region of the drinking opening of a cup. Cups, in particular made of plastic or cardboard, usually have a drinking rim surrounding the drinking rim, the one to the outside

CONFIRMATION COPY has circular flared cross-section. This is then gripped by known snap structures known generic lid snapping form-fitting. For this purpose, the lids are known to adapt both in the diameter of the lid edge near snap structure and in the Schnappöffnungs- width to the cup geometry, for which they are intended.

Thus, the known lid not only serve to close the cup-drinking opening, but even then the drink from the lidded cup is possible, the lid usually also have a drinking passage, which is located near the edge of the lid. There, the user can put on the lid to drink his lips and suck through the passage of the drinking liquid from the cup.

The disadvantage of the use of this known lid is that for reliable drinking the drinking passage with the lips must be taken exactly. Thus, drinking with lid differs from the usual drinking from a cup without a lid, namely, if the lips can be attached anywhere on the edge of the cup opening. Even this deviation is disadvantageous. In addition, however, the preparation of the lips on the lid surface around the drinking passage creates an unfamiliar and not least unsafe drinking, because unlike the drinking at the unsealed cup edge the lips do not enclose the cup rim, but the upper lip rests on the lid only.

The invention is based on the object to provide a still reliable drinking cup lid, through which can drink in the usual way.

This object is achieved by a drinking cup lid with the features of claim 1. Preferred embodiments are specified in the subclaims.

The drinking cup lid according to the invention has a lid edge for sealing insertion into the drinking opening of a cup. According to the invention, this edge of the lid can be designed, for example, conventionally as described in the introduction with a snap edge. On the filing date of this application, the applicant extends this Application but also a likewise directed to a drinking cup lid registration, which has a relation to the prior art more secure cover-cup connection to the object. Its wording is incorporated by this reference in this application, so that the there registered lid-cup connection with all your there described, illustrated and claimed possible embodiments in this application is disclosed as a possible embodiment of the lid according to this invention.

Preferably, at least the lid edge is adapted to the drinking opening of a particular cup geometry or this to the lid edge so that the lid can be sealingly inserted into the cup-drinking opening.

According to the invention, the lid is characterized in that a plurality of drinking passages (individually or in turn several as drinking passage groups) are evenly distributed on at least one circumference of the lid, in particular on the circumference of the lid rim. Thus, as usual, the user can drink at virtually any point on the edge of the lid - and with a sufficiently large number of drinking passages, if the passages are preferably at least approximately the lip opening width when drinking (about <2 cm).

The passages are preferably distributed evenly near the edge of the lid on the circumference of the lid edge, are therefore preferably in the region of the edge relatively close to it, namely, preferably quite soon, when the cup of drinking liquid is tilted so that it from the inside not only against the beaker wall, but also against the lid (initially in an edge region of this) is pending, the liquid escapes from the passages. Preferably, the passages are closer to the edge of the lid than 20% (most preferably closer than 10%) of the lid diameter passing through the respective passage.

The drinking passages may be, for example, circular openings or, for example, slit-shaped, and then preferably extend in the circumferential direction.

For example, as a circular openings, the drinking passages each have such a small passage area (for example needle-like with about 1 mm diameter), that only a number of them at normal Usual pressure drop in a water-like drinking liquid between the lid outside and inside cover (when sucked while drinking it or in a preferred embodiment, the drinking liquid about tilted cup only with their hydrostatic pressure from the inside against the lid is pending) a usual drinking flow rate let through, this number is distributed over a distance of approximately <3 cm on the circumference of the lid.

In this embodiment, the passages each remain very small in size, which reduces the risk that drinking liquid accidentally spills through it. In addition, the lid (compared to slot-shaped in the circumferential direction extending passages) more connecting web material between the lid edge and the lid center surface. And sufficiently large passage cross-section (which should preferably be ensured in some embodiments of the invention to this extent in areas or by a passage) is also ensured.

Within the lid edge, the lid surface can be at least partially clamped flat. So it is suitable, particularly visible and printable, for advertising and decorative applications. And / or it may be in the direction of the inside lid inside curved lid surface section (or lying as far enough deep from the edge), so that the lips and not least the nose while drinking with no lid as possible (compared to "lidless" drinking unfamiliar ) collide.

For this purpose, an outer edge of the lid surrounding the lid as an upper drinking edge is followed by an annular drinking surface which points radially inward on the outer side of the lid and which extends around the lid in the circumferential direction of the lid and which extends in the axial direction Direction of the lid extends from the lid outer edge over a height between 40 mm and 5 mm, in particular 30 mm and 10 mm. Thus, the lid according to the invention preferably even cup-shaped sitting on the cup opening with the Trinkrand- outer edge as the upper edge and the drinking surface as the inner wall. At these two lips of the user can lie in the usual way when drinking and the Take drinking liquid from there, which has flowed through one or some of the evenly distributed on the circumference of the lid drinking passages in tilting the cup in this cup-shaped lid outside - but at preferably so shallow depth of this cup shape that on the one hand the lips the reason of this cup shape at best straight So just reach and so enclose as usual an edge of a cup shape and that on the other hand in the cup-shaped lid, the liquid exiting there from the passages of the lips immediately as swallowed as possible completely absorbed and therefore can not be spilled.

Preferably, the drinking surface tapers in the axial direction of the lid from the upper drinking edge in the direction of the lid inner side and is particularly preferably conical, so it tapers straight.

These and other advantages and features of the invention will be further described by the following figures of embodiments of the invention, wherein:

A drinking cup 2 for warm or cold drinks for disposal of cardboard coated on the inside with plastic (turned off on a horizontal plane 4 as intended) has a drinking opening 6 at the top and an annular rim 8 at the bottom, which makes it possible to place the cup on a horizontal plane 4, so that the drinking liquid 10 remains in the cup. The cup is rotationally symmetrical overall about a vertical axis 12 and tapers not only in the area of the drinking opening 6 but in total with its peripheral wall 14 from the edge 16 of the drinking opening axially downwards (along the axis 12).

The drinking opening 6 is surrounded by a drinking rim 16, which has a circular cross-section flared to the outside.

The cup 22 contributes to preventing the liquid to spill therein, a lid 20 which can cover the drinking opening 6. The lid 22 is injection molded from recyclable polypropylene.

The lid 22 has a lid edge 24 which is sealingly inserted into the drinking opening 6 of the cup (Fig. 4). An annular sealing surface 24 of the lid edge is adapted to the geometry of the drinking opening 6 of the illustrated cup 2 so that the lid 22 can be sealingly inserted into the cup-drinking opening 6.

The annular sealing surface 24 faces radially outward, extends circumferentially around the lid 22 and tapers in the axial direction of the lid (along the axis 12) from the lid outer 26 to the lid inner side 28. Thus, the lid 22 has one, so to speak plug-like structure with a straight conical outer contour 24. The sealing surface 24 tapers doing so with the same pitch as the inner diameter of an annular surface portion 30 below the Trinköffhungs inner edge 16 of the cup geometry, and is therefore adapted in this way to this cup geometry. By adhesive forces and a certain solid eyes even small amounts of drinking liquid that can pull through sloshing and capillary action between the sealing surface and the annular surface portion, and by wedging action of this cover 22 is fixed in the Becheröffhung 6. For this purpose, a user can push the lid 22 into the cup-drinking opening 6, with a slight pushing is sufficient to effect the wedge effect in the cup opening.

In order not to press the lid 22 deep into cup 2 and therefore to be able to remove it from the cup again simply and safely, a radially outwardly projecting portion (at the region of the larger outside diameter of the sealing surface 24 tapering downwards) is divided Stop collar 32, which rests upon stronger pushing the lid into the cup opening from above against the drinking edge 16 of the cup opening.

So that the lid 22 not only serves to close the cup-drinking opening 6, but then also still drinking from the lidded cup is possible, the lid has a plurality of drinking passages 34 along and near the edge 24 of the lid 22 evenly are distributed on the circumference of the lid edge 24.

The drinking passages are distributed individually according to FIG. 5 a, b and d or, in turn, a plurality of drinking pass groups according to FIG. 5 c, distributed uniformly on the circumference of the lid rim 24. Thus, the user can drink at a sufficiently large number of drinking passages 34, namely, when the passages about at least the lip opening width when drinking (about <2 cm) from each other, as usual at any point of the lid rim.

The passages are distributed evenly around the edge 24 of the lid 22 on the circumference of the lid edge, namely, namely, rather soon, when the cup of drinking liquid shown in FIG. 6 is tilted so that they no longer only against the cup wall 14, but also against the lid 22 (initially in an edge region 36 of the lid surface 38 of this) is present, the liquid emerges from the passages 34.

The drinking passages 34 are shown in FIG. 5b and c circular openings or according to FIGS. 1 and 5 a slot-shaped extending in the circumferential direction.

As circular, needle-like openings with a diameter of approximately 1 mm, the drinking passages 34d according to FIG. 5d each have such a small passage area that only a number of them at a customary pressure gradient in a water-like drinking liquid between the lid outer side 26 and inner lid side 28 (when drinking the drinking liquid 10 with tilted cup 2 with its hydrostatic pressure from the inside against the cover 22 is present, as shown for example in Fig. 6) pass a usual drinking-flow rate 40. This number is distributed over a distance of about 2 cm on the circumference of the lid 22.

The drinking passages 34 are arranged in edge depressions 42 which extend like a spout into the lid, that is to say in the direction of the lid inner side 28. This advantageously has the effect that, as just described in the situation according to FIG. 6, a quantity of drinking sludge 40 exits the drinking passages 34 to the outside through hydrostatic pressure. However, if the cup 2 is inadvertently moved more vigorously and the drinking liquid 10 then starts to move, this arrangement reduces the creation of additional back pressure at the drinking passages 34, which could cause excessive leakage of drinking liquid 10.

Within the scope of the drinking passages, the lid surface 36 for advertising and decoration applications 44 is just clamped. So that the lips and not least also the nose of the user (not shown) collide when drinking with as little cover area as possible (which would be unfamiliar with "cap-free" drinking), an outer edge of the lid surrounding the lid closes radially as the upper drinking rim inside an annular drinking surface 46 which points radially inwardly on the lid outer side 26 and which extends in the circumferential direction of the lid 22 around the lid and in the axial direction of the lid 22 extends from the lid outer edge over a height of about 20 mm. Thus, the lid 22 according to the invention sits even cup-shaped on the cup opening 6, with a drinking edge outer edge 32 as the upper edge and the drinking surface 46 as an inner wall. At both of these, the lips of the user (not shown) can lie in the usual way while drinking and receive the drinking liquid 10 from there, which by one or some of the evenly distributed on the circumference of the lid 22 drinking passages 34 in tipping the cup 2 in this cup-shaped Lid outer side 26 has flowed - but at such shallow depth of this cup shape 26 that on the one hand the lips reach the bottom 36 of this cup shape just just so and as usual enclose only one edge 32, 46 of a cup shape and the other in the cup-shaped lid 22nd the liquid 10 issuing therefrom from the passages 34 can be swallowed as completely as possible at once - and therefore this liquid 40 can not be spilled.

The drinking surface 46 tapers in the axial direction of the lid 22 from the upper drinking edge 32 in the direction of the inner lid side 28 conical, ie straight.
