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 broadest sense according to the invention are understood vessels that can grab and lift up according to size and weight with one hand intended and have 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) are rotationally symmetrical at least in the region of the opening about an axis perpendicular to the standing surface and at least in the region of the opening at least with its inner wall from the edge axially downwards rejuvenate.

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

CONFIRMATION COPY usually a drinking rim surrounding the drinking rim, which has a circular outwardly 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.

So that 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.

Another disadvantage is that even in spite of the lid on the cup drinking liquid can slosh out through the drinking opening and can provide impurities.

The invention is based on the object to provide a reliable drinking cup lid.

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.

Preferably, 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.

Furthermore, the drinking cup lid according to the invention has a drinking passage device.

According to the invention, the lid is characterized in that the drinking passage means in the closed position linearly delimits a first surface area of the lid from a second surface area of the lid and that pressure on one of the area areas or a third area area makes the first area area movable relative to the second area area that the line-shaped drinking passage device can be formed and enlarged as a slot-shaped drinking passage.

Preferably, the line-shaped drinking passage means is initially formed as a predetermined breaking line, ie even closed materially closed, and it can then be first broken open by the pressure. In this embodiment, the lid according to the invention is preferably initially completely sealed and without drinking passage. Only after breaking open then forms the linear drinking passageway device as a slot-shaped drinking passage and can be increased by additional pressure.

In any case, the invention allows an advantageously much safer transporting a drink in a cup, which is covered with the lid according to the invention (in the closed position).

According to the invention, an open position in which the linear drinking-through device is designed as a drinking passage can be dimensionally stable. Preferably, the closed position is dimensionally stable. When the pressure is released, the first surface area relative to the second surface area can also be in the closed position spring back. In a possible embodiment, one must then actively hold the pressure in an open position, for example with one finger, by means of the pressure. With decreasing pressure of the lid according to the invention then closes automatically. But this can also be realized in addition to the dimensionally stable open position. Then preferably an unlocking operation makes it possible to bring the cover from the dimensionally stable open position into any other shape in which it can then close automatically.

According to the invention, the "orientation direction" of the passage and the opening means that the opening and the passage are surrounded by an edge which spans (or at least from) respects a surface the opening is surrounded by peripheral edge segments which span a surface) on which the "orientation direction" is at right angles. Thus, if the surface is not a plane but a spatially warped, curved surface, the aperture will have many directions of orientation, but in most practical cases they will deviate only in a range of less angular degrees. The orientation direction of the drinking opening preferably differs from the orientation direction of the drinking opening of the cup by at least 45 °, particularly preferably between 60 ° and 90 °. But even greater than 90 ° is according to the invention (the sense of direction of the orientation direction of the passage and the opening points into the cup in the intended use of the lid). As a result of this orientation according to the invention, the drinking liquid does not splash in its main direction against the orientation direction of the drinking passage, ie directly out of it, but tangentially to the surface which is spanned by the rim of the drinking passage.

It is inventively preferred that a plurality of drinking passages (individually or even several more than drinking passage groups) are evenly distributed on at least one circumference of the lid, in particular on the periphery of the lid edge. Thus, the user as usual at almost any - and with a sufficiently large number of drinking passages, if the passages preferably at least about Lip opening width when drinking (about <2 cm) are separated from each other, drink at any point of the lid margin.

Passages are preferably arranged near the edge of the lid, are therefore preferably in the region of the edge relatively close to him, namely, that is, rather soon, when the cup of drinking liquid is tilted so that it no longer only from the inside 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 can each have such a small passage area (for example needle-like with about 1 mm diameter), that only a number of them at normal pressure gradient in a water-like drinking liquid between the lid outside and inside lid (when sucked when drinking it or in a preferred embodiment, the drinking liquid approximately at a tilted cup with its hydrostatic pressure from the inside against the lid is present) pass a usual drinking-flow rate, this number is distributed over a distance of about <3 cm on the circumference of the lid.

In this embodiment, the passages each remain very small area, which further 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 a lid surface portion curved in the direction of the inside of the lid (or lying flat enough from the edge), so that the lips and not least the nose when drinking with as little cover area (unfamiliar to "lidless" drinking) collide.

For this purpose, in a preferred embodiment, an outer edge of the lid surrounding the lid radially inwardly adjoins an annular drinking surface which points radially inwardly on the lid outside and which extends around the lid in the circumferential direction of the lid and extending in the axial direction of the lid 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 may preferably even cup-shaped sitting on the cup opening with the drinking edge outer edge as the upper edge and the drinking surface as the inner wall. At these two lips the user can lie in the usual way while drinking and take the liquid from there, which has flowed through one or some evenly distributed on the circumference of the lid drinking passages in tilting the cup in this cup-shaped lid outside - but preferably so shallow depth of this cup shape that on the one hand the lips reach the bottom of this cup shape just just so and as usual enclose an edge of a cup shape and that on the other hand in the cup-shaped lid, the liquid exiting there from the passages from the lips immediately swallowing as completely as possible recorded and so 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: 1 is a bottom view of a lid according to the invention,

8 is a sectional side view of the lid according to the invention of FIG. 6 in the open position,

A drinking cup 2 for warm or cold drinks from the inside with plastic coated cardboard (for disposal) has (intended parked on a horizontal plane 4) above a drinking opening 6 and below an annular stand edge 8, the stopping of the cup on a horizontal plane 4th allows 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 2 contributes to preventing the drinking liquid from spilling therein, a lid 20 which can cover the drinking opening 6. The lid 20 is injection molded from recyclable polypropylene.

The lid 20 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 20 can be sealingly inserted into the cup-drinking opening 6.

The annular sealing surface 24 faces radially outward, extends circumferentially around the lid 20 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 20 has one, so to speak Plug-like structure with a straight conical outer contour 24. The sealing surface 24 tapers with the same pitch as the inner diameter of an annular surface portion 30 below the inner opening of the drinking opening 16 of the cup geometry, and is therefore adapted in this way to this cup geometry. By adhesion forces and a certain firm eyes even small amounts of the drinking liquid 10, which can draw by sloshing and capillary action between the sealing surface and the annular surface portion, and by wedging action of this cover 20 is fixed in the cup opening 6. For this purpose, a user can press the lid 20 into the cup-drinking opening 6, wherein a slight pushing is sufficient to effect the wedge effect in the cup opening. But also, for example, a conventional snap edge can be realized for the lid according to the invention.

So that the lid 20 not only serves to close the cup-drinking opening 6, but then also the 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 20 evenly are distributed on the circumference of the lid edge 24.

The drinking passages 34 are slit-shaped (FIGS. 3 to 5 and FIG. 8) distributed uniformly on the circumference of the lid 20. So the user can with enough large number of drinking passages 34, namely, if the passages are at least about the lip opening width when drinking (about <2 cm) apart, as usual drink at any point of the lid margin.

The passages 34 are evenly distributed near the edge 24 of the lid 20 on the circumference of the lid edge, namely, that is preferably quite soon, when the cup of drinking liquid shown in FIG. 5 is tilted so that they no longer only against the beaker wall 14 from the inside but also against the lid 20 (initially in an edge region 36 of the lid surface 38 of the latter) is present, the liquid emerges from the passages 34.

The drinking passages 34 are arranged in edge depressions 42, which extend into the lid, that is to say in the direction of the lid inner side 28. This advantageously has the effect that, in the situation according to FIG. 5, 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 38, for example, also for advertising and decorative applications on the outside 26 of the lid surface 38 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 20 around the lid and extending in the axial direction of the lid 20 from the lid outer edge over a height of about 20 mm. Thus, the lid 20 according to the invention is itself cup-shaped in the cup opening 6, with the drinking surface 46 as the inner wall. At this the lips of the user (not shown) may lie in the usual way while drinking and the drinking liquid 10 of pick up there, which has flowed through one or some of the evenly distributed on the circumference of the lid 20 drinking passages 34 in tilting the cup 2 in this cup-shaped lid outer side 26 - but at such shallow depth of this cup shape 26, that on the one hand the lips 38 of this reason Cup shape just just reach and thus just as usual enclose only one edge 46 of a cup shape and on the other hand in the cup-shaped cover 20, the leaking there from the passages 34 liquid 10 immediately swallow as completely as possible - and thus this liquid 10 can not be spilled ,

The drinking surface 46 tapers in the axial direction of the lid 20 from the upper drinking edge 32 in the direction of the inner lid side 28 conically, so straight.

The drinking passages 34 have an orientation direction that is different from the orientation direction of the drinking opening 6 of the cup.

"Orientation direction" of the drinking opening 6 means according to the invention that each drinking opening 6 is surrounded by an edge 16 which spans a (imaginary, here circular, planar, not shown) surface on which the "orientation direction" 45 is at right angles (47).

"Orientation direction" of the drinking passage 34 means here that the drinking passage 34 is surrounded by relative to the drinking passage 34 opposite edge segments 48, which spans (imaginary, in Fig. 3 to 5 and 8 conical surface segment-shaped) surface 49 on which the "Orientation direction" 12 is approximately at right angles. Because the surface 49 is cone-shaped surface segment-shaped and thus no plane but a spatially curved curved surface, each of the drinking passages 34 (infinity) many orientation directions 52, but also differ in this practical case only in a range 54 fewer degrees.

According to FIGS. 3 to 5, the orientation direction 50 of the drinking passage 34 differs from the orientation direction 12 of the drinking opening 6 of the cup 2 by approximately 88 ° (the direction of orientation of the orientation direction of the passage 34 and the cup drinking opening 6 are in the cup 2 in all figures in). The Orientation direction of the drinking passage 34 is directed through the cover 20 radially outward and (slightly to) above. The bottom of the edge segments 48 (which is the imaginary conical surface segment fb ^'-shaped surface 49 together with the upper of the edge segments 48 subtending) is the outer edge of a punched in their contours series of blades 56 which are adjacent to each other are folded from the drinking passage 34 to the outside below and thus release and form the drinking passage 34.

According to FIG. 8, the orientation direction of the drinking passage 34 differs from the orientation direction of the drinking opening 6 of the cup 2 by approximately 92 °, the direction of orientation of the drinking passage 34 is directed radially outwards through the lid 20 and (slightly) upwards into the cup 2 , The upper of the edge segments 48 (which spans the imaginary conical surface segment-shaped surface 49 together with the lower of the edge segments 48) is the inner edge of a contours-stamped series of fins 56 folded side-by-side upwardly from the drinking passage 34 and so on Release the drinking passage 34 and form.

As far as the lid 20 is always described in the open position of the drinking passage means 34. However, the lid 20 can also assume a position in which the drinking passage device 34 is closed (FIGS. 1, 2, 6 and 7). Then, the drinking passage means 34 is linear and delimits a first area 56 (the fins 56) of the lid from a second area 57 of the lid. By pressing on a third area 38 (the center of the lid 20 adjacent to the second area 57 in each of the linear drinking passages 34), the first area is movable relative to the second area so that the linear drinking passageway forms as a slit-shaped drinking passage 34 (FIG 3 to 5 and 8) and increased pressure.

The line-shaped drinking-through-passage device 34 is initially (FIGS. 1, 2, 6 and 7) designed as a predetermined breaking line 34, ie even closed by a material fit, and it can then be broken open by the pressure. Thus, the lid 20 is initially completely sealed and without trained drinking passage. Only after breaking up then forms The line-shaped drinking passage device as a slit-shaped drinking passage and can be increased by additional pressure.

The open position in which the linear drinking passage device is designed as a drinking passage, as shown in FIG. 3 to 5 and 8 is dimensionally stable.

When the pressure is released, the first surface region relative to the second surface region can spring back into the closed position, as shown in FIGS. 1, 2, 6 and 7. It is then necessary to hold the lid in the open position by means of pressure (for example with a finger on the middle 38). With decreasing pressure of the lid according to the invention then closes automatically.
