The invention relates to thin-walled containers and especially on cups «which are manufactured by Vaouumverf croning of thin-walled thermoplastic material and be used in vending machines, for example «

Am the ideal cup for use in vending machines

should have a low stacking height, so that a maximum

Number of cups within a given supply

can be accommodated in the room «Since the cups are

must be separated by gravity »If a tight"

Stacking impossible because of the resulting negative pressure

and the friction makes it difficult to separate one cup at a time.

Therefore, such a cup must be shaped like this "daJ Be"

proposed a large number of forms that performed these tasks to varying degrees.

Cups for giving off drinks should also have one The largest possible cylindrical area for holding printed tferhehinwelsen have · Most shapes for However, there is stabilization in the side walls, which limits the area to be printed on. Stabilizations in the bottom wall do not affect the pressure area but change the usable volume and are usually difficult to manufacture and not sufficiently strong and z ^ t

Ss if? * "Therefore object of the invention" a very strong and to create stable, stackable cups »for one maximum number of individual cups within a given Height can be stacked * with a maximum area for the inclusion of advertising prints.

This task is done with a one-tier, stackable container mm dUnnero plastic material with a bottom and a

According to the invention, the circumferential side wall is valid because the circumferential sidewall extends up and down from the bottom forming a frustoconical lower section " that at the top of this section a sharply outwardly curved conical section connects, that the conical section into a frustoconical one extending upwards and inwards short section that merges into one outward rolled lip with essentially circular cross-section » ends, and that the inside diameter of the rolled lip is smaller ™ 1st as the outer diameter of the conical section

The container according to the invention therefore has a very long one frustoconical lower section, and within one Stack, the conical section forms a Rlngsohulter, the rests on the lip of the container into which the outgoing container used 1st.

The invention is described below on the basis of an embodiment · - { belsplel-showing figures explained in more detail

FIG. 1 shows, partly as a view, partly as a section, a container according to the invention.

In a representation similar to FIG. 1, FIG. 2 shows a stacks consisting of three inventive containers.

FIG. 3 shows a part of the three containers from Figure 2

The container 10 shown in Figure 1 is made of a thin Plastic sheeting, for example made of polystyrene, "the alttele" usual Vacuunformververfahren and the associated device was deformed * The container shown has the shape «like they usually for cold drinks, especially for those Dispensing of carbonated cold beverages from vending machines can be used·

Cup 10 has a bottom 12 ″ of the usual shape However, in the diet shown here, one example can be used recessed area so that the floor is stiffened and a stable lower edge is formed. Bine peripheral wall 14 runs from the bottom IS up and out, so that a cone-shaped pot-shaped section is created · This frustoconical Section 14 ends at an upwardly curved section 16 "which has an arcuate cross-section" as in more detail will be described · At the outwardly bent section 16 sleeps a truncated cone opener pointing upwards and inwards Section 18 at "the in a rolled lip 20

ends, which in the »eeentlioben a circular cross-section bat and made by means of a ttblioaer lip rolling deviceea can be·

In Figures 2 and 3 * especially in the enlarged Representation according to Figure 3 recognizes »by» that the outside diameter

knife of the upper part of the outwardly curved section 16 is much larger than the JOmendurohsiesser of the ge »f rolled lip 20 «The difference between these diameters 1st by the slope and the lungs of the upper truncated cone shaped section 18 given «Since this truncated cone» The fttTMlge section is close to the opening »can be

Incline very large, for example 7 ° * so that you can Length of section 18 can be kept very small and looser

still a significant difference between the outer diameter knives the center of the abutment, which is bent outwards, and the inside

diameter of the rolled lip 20 reaches «j

The n * oh must curved section 16 has a curved cross-section, whose outer surface has the same radius as the Cover the rolled lip 20 »so that a great touch * - area is created »Duroh the curved fora of the section a stiffening of the panel is achieved that on the rolled lip rests «which is the strongest and represents the stiffest part of the cup · The short axial lens

and gives the near inward inclination of section ·· 18 a significant gain. These three characteristics together ollden an annular portion that has a cross-section which has the shape of a straight band opposite to In Directions curved edges bat * so that a maximum strength and rigidity is given * by the large contact * - The area and the shape of the adapted Plftoheu result a very stable stack minimum stacking height for a given number of containers. In addition, the given rare wall is available for printing with instructions. Although the invention to Hatid one preferred execution term was described "is it clear" that various changes and modifications are possible all fall under the invention
