Drinking cup made of thin-walled plastic

The invention relates to a drinking cup made of thin-walled plastic, in particular for hot drinks, which differs from the Bottom is flared to the upper edge and partially double-walled.

Double-walled cups, in particular drinking cups, are known in which two complete cups are nested and on Opening edge are connected to each other. Also known are drinking cups of this type, their outer double-wall part element is open at the top and bottom, and at the top has a curled edge and at the bottom an inwardly folded edge

JJ edge have. The actual cup insert is through the

Upper cup opening hooked into the double wall element. the The cup insert lies with its upper edge around the flanged edge of the double wall element and supports itself with it its bottom on the bent edges, which are also designed as a border. The cup insert is radial designed in wave form in order to have a stabilizing effect as well as to allow only the least possible heat transfer.

Furthermore, cup designs of a similar type are known, the conically shaped cup ^ at its upper end to the outside is crimped and provided at its lower end with a curved bottom, so that there is a special adjustment edge. The· The cup is placed from above into an outer cup, which is also conically shaped and which is about halfway up at its upper end three-quarters height of the cup has an inwardly beaded rim and an edge directed towards the inside of the cup on its open bottom having. The wall of the cup clamps against the inwardly directed flange of the insert and provides support with its edge on the inwardly directed edge of the cup insert.

The disadvantage of the known double-walled cup in the first two cases is based on the fact that the production of the cup is very

is material and labor intensive. Two cups with a smooth conical shape must be produced, to find insulation against heat.

In the third known embodiment, too, too much material is required. As a major disadvantage, however, is to assess that there is no heat protection arranged especially on the upper part of the cup with the drinking rim.

In contrast, the invention is based on the object of producing a drinking cup that does not have these disadvantages, which is simple in its construction, as low as possible in its material costs and low in its manufacturing costs is held.

This object is achieved in that the Wall of the drinking cup has at least two areas of different conicity and in the area of greater conicity the outer surface of the cup wall reinforcing the cup wall and has a grip ring that insulates against heat transfer.

The part designed as a grip ring can preferably be the Already cover the larger conicity completely and thus also against the upper edge of the drinking cup, which is designed as a drinking wall Be protected from heat transfer.

In one embodiment of the invention, the grip ring, the at its upper end with a radially outwardly extending one Splash and is formed at the lower end with an edge directed towards the inside of the cup, from below the cup part pushed on and crimped with its s ± ii outwardly radially extending flange into the Beoherrand and is supported with its lower edge directed towards the inside of the cup in a lower edge at the transition point between the part Conicity, partly larger conicity, formed inwardly directed circumferential bead: ab.

The grip ring can be made deep-drawn from thin-walled plastic and be pushed onto the area of greater conicity from below.

But it is also possible within the scope of the invention that the (Jriffring is made of other diverse materials and attached in different ways.

Some embodiments of the invention are shown in the drawing and are explained in more detail below. It show:

Pig. 1 is a side view of the drinking cup with a grip ring; Pig. 2 shows a side view of the grip ring from FIG. 1;

The one in Pig. 1 with a handle ring 4 shown drinking cup has two areas 2, 3 of different conicity. Oer lower, less conically shaped upper part 2 is from the rigid

ker konisoli shaped upper cup part 3 through, one towards the inside directed circumferential science 9 separately. The cup part 3 of greater conicity has at its upper end an outwardly beaded one Edge 8 on. The grip ring 4 (Fig. 2), on its outer surface axially extending handle ribs 7 are arranged, a larger conicity is aufweicenden from below on the upper Cup part 3 pushed on. The one that extends radially outward flange-like upper edge 5 of the grip ring 4 is in on the upper cup part 3 is crimped into the edge 8 of the drinking cup in the pushed state. The lower end with a to The edge 6 of the grip ring 4 facing the inside of the cup is supported in the circumferential bead 9.

In a further embodiment, the grip ring 4 is instead of a flange-like edge 5 extending radially outwards only provided with a smooth edge (Pig. 3) The lower edge 6 of the grip ring 4 is designed as described above. In pushed onto the upper part of the cup 3 In the state (Fig. 3), the upper edge of the grip ring 4 is under tension against the flanged edge 8 of the upper part of the cup 3 and is supported with the lower edge 6, which is slightly inwardly formed, in the circumferential bead 9.

The grip ring 4 shown in Fig. 4 has at its upper

Edge an outwardly directed bead 13 and below this Bead 13 "before the outer wall of the grip ring 4 conically

on runs, a narrow strip 14 around the circumference V'Durch Arranging the strip 14 below the bead 13, a notch is formed between the bead 13 and the strip 14. The lower The edge of the grip ring 4 is formed with a straight edge 15. .. In Fig. 5 is the one on the upper part 3 of the Drinking cup 1 pushed-on handle ring 4 reproduced. The bead 13 of the grip ring 4 is crimped within the Edge 8 of the drinking cup 1 added and the edge of the flanged edge 8 is pressed into the notch between the bead 13 and strips 14. In contrast to the previously described versions of the deep-drawn made of thin-walled plastic Grip ring 4 consists of the one in Fig. 4 and Pig. 5 shown Grip ring 4 made of thick-walled foam, which also consists of two areas 2, 3 of different conicity Drinking cup 1 has no circumferential bead 9 at the transition point on.

In a further exemplary embodiment, which is shown in FIG. 6 is, the drinking cup 1 also has no circumferential smoke 9 on. The grip ring is here by one or more blanks attached to the cup, preferably a segment 1? (Fig. 7), educated.

Foam is made in the upper cup part 3 in such a way attached, for example, glued that the side edges of the segment 17 butt against each other. The heat insulating segment 17 can be made of foam, i.e. H. foamed plastic, for example, foamed polystyrene, paper, cardboard or Paper mache exist, and points to its outer surface Increasing the grip security diamond-shaped fields 18, whose acute angled corners are arranged above and below.

The lower cup part 2, which has a smaller conicity a3r the upper cup part 3, is in all exemplary embodiments smooth-walled and can be printed.

The upper cup part 3 favors a possible by its conicity and also by its outwardly beaded edge 8 Stacking of empty containers.
