Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In the following, advantageous embodiments of the lid are described in more detail using the Figures included in the drawings.

[0033] FIG. 1 shows a perspective top view of a cup with lid;

[0034] FIG. 2 shows a cut along a diameter of the lid as shown in FIG. 1 for a first embodiment;

[0035] FIG. 3 shows a cut analogous to FIG. 2 for a further embodiment, and

[0036] FIG. 4 shows a perspective top view of another embodiment of a lid according to the invention.

DETAILED DESCRIPTION

[0037] FIG. 1 shows a perspective view from an inclined position on top of a cup 2 with a lid 1. The cup 2 has an essentially truncated cone shape with an upper cup rim 3 on which the lid 1 is placed in an essentially liquid-tight manner. The lid 1 has a circular shape and comprises a lower lid part 4 and a lid disc 5. The lower lid part 4 is essentially annular and the lid disc 5 is essentially circular. Depending on the diameter of the cup 2 at its upper cup rim 3, the diameters of lid disc 5 and lid lower part 4 can be selected.

[0038] The lower lid part 4 has a structure in the height direction which, for example, has an inwardly projecting locking bead 22, see also FIGS. 2 and 3, which, for example when lid 1 is placed on cup 2, engages under a cup rim which is generally rolled over outwards.

[0039] The upper side of the lid disc 5 is essentially flat and, in the embodiment shown, has a drinking straw insertion point 18, which is formed by at least one cut line 20. A plurality of cut lines 20 are also conceivable, whereby these are arranged in an X-shape, for example, and a drinking straw 19 is placed with its lower end on a corresponding intersection of the cut lines 20 and then advanced through the lid disc 5 into the interior of the cup 2.

[0040] Furthermore, or as an alternative to the drinking straw insertion point 18, the lid disc 5 can have a drinking opening 21, which is designed, for example, as a lid disc section 24, which is bordered by a cut line 25. The shape of the lid disc section 24 can be circular or also formed in another way, for example drop-shaped in the direction of the rim groove 6. In order to press the lid disc section 24 into the inside of the cup or to lift it at least partially from the lid disc 5, a handle 23 can be arranged on the lid disc section 24.

[0041] It is also possible that the lid disc 5 has neither drinking straw insertion point 18 nor drinking opening 21, so that, for example, no drinking straw 19 or without additional aids can be used to pierce the lid disc.

[0042] In the embodiment of lid 1 according to FIG. 1, a rim groove 6 is formed by an upper rim 10, see also FIG. 2, of the lower lid part 4. The rim groove 6 has an essentially inverted U-shape and a rim flange 8 formed by the lid disc 5 is inserted into the rim groove 6. The rim flange 8 is formed by a lid disc rim 11 pointing upwards in FIG. 2. This is essentially completely inserted into the rim groove 6. Rim groove 6 and rim flange 8 or lid disc rim 11 are connected to each other in a liquid-tight manner.

[0043] At a lower end 26 of the rim groove 6, the lower lid part 4 has a supporting rim 27 which runs obliquely inwards. This is used, for example, for abutting from above and laterally against an upper cup rim 3, which is not shown in FIG. 2.

[0044] The lid disc rim 11 runs essentially perpendicular to the remaining lid disc 5, which extends between the circumferential rim groove 6 of the lower lid part 4.

[0045] A liquid-tight connection between the rim groove and rim flange can be achieved in all embodiments by means of an additional adhesive or by a plastic coating 17 applied to at least one underside of the lid disc 16 or upper side of the lid disc. In the latter case, the connection is made by heat sealing, for example.

[0046] It is also conceivable that the plastic coating 17 is not only applied to an underside 16 of the lid disc 5, but alternatively or additionally to its upper side and possibly to an outer side/inner side of the lower lid part.

[0047] In the embodiment shown in FIG. 3, the rim groove 7 is formed by a rim ring 12 at the lid disc rim 11. This also has an essentially inverted U-shape, into which a corresponding rim flange 9 of the lower lid part 4 is inserted from below, the rim flange 9 being formed by an upper end section 13 of the lower lid part 4. Also in the embodiment according to FIG. 3, a supporting rim 27 is formed substantially at the lower end 26 in this case of the rim flange 9 or the upper end section 13 of the lower lid part 4. Preferably a depth 14 of the rim groove 6, 7 corresponds to a height or length 15 of the corresponding rim flange 8, 9.

[0048] To simplify matters, FIGS. 2 and 3 do not show a drinking straw insertion point 18 or a drinking opening 21. A drinking straw insertion point 18 is usually not provided for hot beverages. Likewise, the drinking opening 21 can be a simple opening in the lid.

[0049] It should also be noted that the drinking opening 21, see FIG. 1, does not have to be at a distance from the corresponding rim groove 6, 7, but can also extend to and along the rim groove.

[0050] In both embodiments of FIGS. 2 and 3, the locking bead 22 is shown in each case, whereby there is an upper cup rim between this and the lower end 26 when lid 1 is placed on a cup 2. The locking bead 22 engages under the corresponding upper cup rim, which may be rolled over outwards.

[0051] FIG. 4 shows a top view of another embodiment of a lid according to the invention. This has a lid disc section 24, which closes off a drinking opening 21 in the lid disc 5. The lid disc section has a press-in section 33 facing the rim groove 4 or 6 and an adjoining fold-up section 34. The press-in section 33 is bordered by a front line section 30 and a middle fold line 35. The front line section continues in two side line sections 31, 32, which end at an end fold line 29. The front line section and the side line section are tearable or can be pushed in and form a tear line 28 to separate the lid disc section from the remaining lid disc 5 along this line. The front line section 30 is essentially convexly curved and is assigned according to the rim grooves. The side line sections run in a substantially straight line, with the middle fold line running between their ends facing the front line section. In the embodiment shown, the middle fold line runs essentially parallel to the end fold line and is longer than it.

[0052] To open the lid disc section, the user presses the press-in section 33 with a finger so that it separates from the rest of the lid disc 5 along the front line section 30. If the press-in section is then pivoted towards the inside of the cup about the middle fold line, the lid disc section is further separated from the lid disc 5 along the side line sections 31, 32 and at the same time the fold-up section is folded upwards, together with the press-in section folded in relative to it, about the end fold line 29. In the open position of the lid disc section, it protrudes from the lid disc along the end fold line 29, the press-in section being at least partially pivoted in the
