Benefits of technology

[0008] Therefore, the invention is based on the object to provide a first and a second shell, which can be produced cost-effectively as disposable units, on the one hand, and on the other hand, allow a largely tightly sealed container by connecting a tight but easily separable lock.

Problems solved by technology

The disadvantage of this production process lies in its relatively high production costs per item.
However, this structural design with two complementary adjusted threads requires an expensive production process.
Furthermore, the seal of the receptacle screwed together is solely implemented by the connected threads, which leads to considerable leaks due to the unavoidable irregularities resulting from the deep-drawing method.
This is particularly unacceptable for packaging food.
This is not only awkward, but it also presents the risk that the fingers come into contact with the content of the receptacle.

Embodiment Construction

[0065]FIG. 1 shows a first shell in the form of a top shell 1. The top shell 1 has a convex pot-type central part 3 arced outward, with its circumferential wall 29 transferring into a holding edge 4. A step like reducing collar 5 is located between the pot-type central part 3 and the holding edge 4. The circumferential wall 29 is provided with a ruffled structure 30 also protruding on the interior 29a (see FIG. 4).

[0066] The holding edge 4 is provided with mounting means 47 in the form of a total of four threads 7a, 7b, 7c, 7d, their contours being embodied both on the inside 6a (see FIG. 3) as well as on the outside 6b of the holding edge 4. Using the threads 7a, 7b, 7c, 7d a second shell (see FIG. 7) embodied as a bottom shell 2, for example, can be fastened to the top shell 1.

[0067] The holding edge 4 is also surrounded at the outside by an encircling punched edge 49. Said edge has a larger diameter than the top shell 1, because it has been separated from a sheeting 23 during t...

Abstract

Disclosed are a top shell (1) or bottom shell (2) made from a deep-drawn molded plastic part as well as a receptacle which is composed of the two joined shells. The invention further relates to a method and a device for producing a top shell or a bottom shell (1, 2). The aim of the invention is to create a first and second shell (1, 2) which can be produced inexpensively as a disposable item while allowing the same to be locked together in a fixed but easily removable manner by joining the two shells together so as to create a largely tight receptacle. Said aim is achieved, among other things, by embodying a reducing collar (5) between the holding edge (4) and the pot-type central part (3) on the top shell (1) while disposing at least two identically pitched threads (7a, 7b, 7c, 7d, 7e, 7f) on the inner face (6) of the holding edge (4). The reducing collar (5) delimits the at least two threads (7a, 7b, 7c, 7d, 7e, 7f) on one side while said at least two threads (7a, 7b, 7c, 7d, 7e, 7f) are provided with an open thread inlet (48).

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a top shell and a bottom shell made from a deep-drawn molded plastic part as well as a receptacle, which is composed of the two joined shells. The invention also comprises a method and a device for producing a top shell or a bottom shell. [0003] 2. Description of Related Art [0004] A combination of a first shell, for example a top shell, with a second shell, for example a bottom shell, results in a receptacle, in which in the joined state the first shell engages the second shell from the outside, with the second shell being embodied with a circular opening edge, and with the first shell protruding from the second shell with its holding edge. Such receptacles serve to store and transport small parts of all sorts, in particular food, such as for example cream cheese, yogurt, and the like, and with the latter also comprising salad compositions provided with dressing or to which dressing remains...
