Plastic containers

The invention relates to a plastic container for filling and storing goods.

The invention is based on the problem that a great many foods, paints, varnishes, lotions and the like (liquids, pastes, powders, granules) in conventional metal, glass, porcelain, plastic, paper and other packaging are subject to change or spoilage as soon as the packaging is opened and parts of it are removed. The more air space there is above the remaining contents, the faster oxidation, drying out, loss of aroma and vitamins, crust formation, changes in taste, crystallization, discoloration, mold formation and much more occur.

The invention is based on the object of designing the container in such a way that the volume can be precisely adjusted and fixed to the amount of filling material in order to be able to minimize the air space above the container contents. A further aim is to be able to reuse the container several times.

The object is achieved by designing the container according to the teaching of claim 1. Advantageous further developments are specified in the subclaims.

The container, e.g. a can or bottle, consists of a semi-elastic plastic cylinder with a thread-shaped wall. This plastic cylinder is shortened by folding it and screwing on a hard plastic rotating bowl with a thread and a storage space for the engaging housing part. The rotating bowl has a counterbearing in the form of a ring. With a right-hand thread, for example, the accordion-like wall collects within the rotating bowl, which is not very easy to rotate, when turned clockwise, so that the container volume can be reduced by up to 2/3. The closure is only screwed on tightly once the filling level has reached the upper edge of the container opening. The problems described below are avoided by the invention. Furthermore, the volume of waste when disposing of packaging can be significantly reduced by disposing of the container in its compressed volume. A further advantage is that, for example, For example, vegetable and soup leftovers can be stored and frozen in the container with almost no air at all, as the container height can be adjusted precisely to the filling volume and... for example, it can be vacuumed by turning it anti-clockwise after closing it with the screw cap. For household goods, food, paints, varnishes or lotions, four different container designs are sufficient to protect the contents of opened sales packaging better than before.

The invention is explained in more detail below with reference to the embodiments shown in the drawings. In the drawings:

FIG 1 A can closure (screw lid) made of plastic.

FIG 2 High rotating bowl made of hard plastic, suitable for screwing on both large cans and large bottles in order to change the volume; the vertical container wall collects in it when turned to the right. A circular

Opening; only one full thread at the bottom edge. The outer wall for labeling.

FIG 3 A can body made of semi-elastic plastic for e.g. 1.0 litre content, with maximum

wide neck opening and with thread-shaped walls. After turning to the left, this flexible wall expands again to a greater height for the full volume of the container. Brown coloring provides light protection for the contents. This

Coloring is so intense that the type of content remains recognizable.

FIG 4 A plastic bottle cap.

FIG 5 A bottle body with an opening of approx. 40 mm, otherwise as for the can body according to FIG 3 .

FIG 6 A flat rotating tray, suitable for both the small can and small bottles, otherwise as FIG 2.

FIG 7 A small can body with e.g. 0.5 litres volume, otherwise as explained in FIG 3.

FIG 8 A small bottle body for e.g. 0.5

According to content, otherwise as explained in FIG 5.

FIG 9 A small can, open, completely compressed in the flat rotating tray.

FIG 10 A small bottle, open, also compressed

FIG 11 An example of a can and bottle emptying scraper.

FIG 12 An example of a bottle brush for internal cleaning.

Claims (5)

1. Container made of plastic, characterized by a flexible wall and the interaction with a rotating bowl, during the rotation of which the container height can be changed, and by a screw closure. 2. Container according to claim 1, characterized in that it comprises: 1. a thread-shaped wall, 2. a screw cap with a screw neck that is smaller than the outer diameter of the container, 3. a rotating bowl with a thread and a longer cylindrical section with a diameter at least equal to the outer thread diameter of the threaded wall of the container and 4. a rotating shell edge as an abutment for a front wall of the container, which rotating shell changes the container height when rotated. 3. Container according to claim 1 or 2, characterized in that the thread-shaped wall has a right-hand thread. 4. Container according to one of the preceding claims, characterized in that the height of the rotating bowl is selected such that the wall of the container can be screwed into the section above the thread and the container can be compressed to approximately 1/3 of its length. 5. Container according to one of the preceding claims, characterized in that the rotating bowl is screwed onto the container from above and the screw neck is passed through its central opening.
