Container open at the top for receiving int essentials. you fix tea

The invention looks at an open-topped container * for receiving essentially solid Gutea that from the same can be removed in one piece, with a recess that • a floor and a rare wall with one flake as well as a Has plan view around the upper end of the side wall

As is known, there are many types of containers for holding essentially solid substances, and these containers each Depending on the nature of the product to be packaged, an approach1 of requirements, such as ventilation, stacking, Stiffness and the like must be sufficient. A known packaging of this type is the so-called shell with cover, in which Im essential solid products, such as fruit, cakes and the like., Housed in a fairly stiff bowl and against influences are protected from the outside by a flexible film welded to the shell that after removing the wrapping, the packaged Out is only insufficiently held in the tray.

This disadvantage is somewhat remedied for ferer shells, but new difficulties arise when removing them of the essentially solid products in one piece the shell on.

The invention is based on the object of these disadvantages to avoid and create a container that has the advantages kept deeper, but at the same time designed in this way is that it essentially fixes an easy removal * Products in one piece.

Bottom 1Ί, which is designed in such a way that it favors deformation or bending inward in the axial direction. This embodiment is more fully understood from Pig. II and III can be seen, after which the bottom 14 has a spiral groove 16 which winds from the central part 18 of the bottom Ik outwards. According to Pig.I, the side wall 12 of the container filter IO is provided with a series of essentially parallel ribs 20 which ensure increased strength with respect to deformation in the lateral and axial directions. As a result of this configuration, a substantially solid product, such as a cup cake 22, located in the container 10 can easily be removed in one piece by pressing the flexible container bottom upwards _{with a finger or by other means, p} being also used Cake upward sehlebt, so that the upper part of the cake 22 can be gripped by hand or other catfish, as shown in Flg. V can be seen.

Fig. IV shows a modified embodiment. dung darρ in which the bottom grooves 24 in contrast to the spiral arrangement according to Fig «II are circular, where the ground is somewhat similar to that shown in Fig. II ο container bottom bends *

Ea is also possible in one container with one in essence flat bottom (Fig. VI) produces an axial bending effect

to call out. In this embodiment, the container has 33 a bottom 32 'whose thickness is compared to that the side wall 30 is relatively small. The in Fig. II and IV grooved configuration shown is preferable to a flat bottom because of the widening of the grooves Pushing up the soil is generally a much larger one Bending effect is achieved. This advantage of the grooved design can be achieved by rounding off and thinning the corner. part 34 of the container 33 having a flat bottom can be partially achieved. Here, however, a considerable «^ in some uses undesirable deformation of the lower part of the side wall occurs when on the container bottom an axial pressure is exerted. As a result, the use of the thin, flat bottom formation is recommended only in cases in which there is no «significant floor deflection is required and / or deformation of the container is not a particular problem

Rent. In order, for example, to prevent the two recesses 42, 44 of the container 40 from collapsing against one another and also to form a reinforcement between these recesses, the axial lengths of the side walls between the recesses are reduced so that the edges 46, 48 of the side walls between the recesses run down quite suddenly to a ridge or section 50 connecting the recesses 42,44 together. In addition, a flange part 52, which can be better seen in FIG. VIII, is firmly connected to the upper edges of the two depressions, with the outer edge of the web region B, where it communicates with the upper extensions 51 of the web or section 50 and essentially horizontally runs on the outside and forms a surface 54 to which a film or sheet, such as the film 56 from Pig VII, can be attached in any way to form a tightly sealed package.

As can be seen from Fig. VIXI, the bottoms 58, 60 are of the wells 42 or 44 designed in a similar "way", as shown in Fig. II, to the flexibility of the floor according to the invention to achieve «It was also found that this floor flexibility can be increased by reducing the thickness of the bottom compared to that of the side wall, so that both the floor design and the desired flexibility as well as the Bodendlok · contributes. In the lower parts of the side wall ribs 4i and 43 are provided «

In general, the containers according to the invention are used for Absorption of essentially solid substances such as cakes, Fruits and the like, fluffy or grainy in the Oegeneatζ Materials. These containers have a base and a side wall integral therewith, the configuration and the thickness of the bottom together serve to provide greater axial flexibility compared to the lateral flexibility to reach the container side wall «Essentially solid Products can therefore be easily removed from these containers in one piece when the bottom is pushed upwards and thereby a part of the packaged goods is pushed over the upper edge of the container side wall, so that it can be taken and removed as a whole from the container.

The container preferred for fulfilling this purpose has a base, the upper edge area of which is integral with it a side wall, the middle part of which is a point or a larger, with regard to the circumference ram!

The total container thickness can vary substantially in a range in which the container base is under finger pressure Can be bent reasonably easily. The invention Containers are generally made of plastics, primarily

Line mainly of thermoplastic type, such as polystyrene and the like; the average sidewall thickness such plastics are generally in the range from 0.0508 to 0.508 and in particular between 0.0762 and 0.25 * 1mm. The average thickness of the floor can be equal to, greater or less than the average rare wall thickness. If the floor thickness is greater than on average that of the side wall, it may be necessary to provide ribs or other elevations in the letsteror to surround the Strength of the rare wall against lateral deformation to be » when.the container is held. The rare wall is generally continuous around its circumference, i.e. seamless, and extends advantageously from the bottom edge in a circular cone upwards and outwards, albeit if necessary other configurations can be used

Figures VII and VIII have a container with more features of the invention.
