description

The invention relates to a cup specified in the preamble of claim 1 protection.

In the production of soft ice cream or the like. Products such as fruit creams, mousses or farces for pies and terrines, a liquid starting mixture in a working cup, which is usually made of stainless steel, frozen. Thereafter, the working cup is used with the solidified starting mixture block in a known household appliance (CH 685 321 A5), in which then with a rotating knife, the block is crushed by chipping, scraping, cutting and / or hitting. Through the use of several such working cups, different ice, fruit od. Like. Mixtures can be prepared in advance and stored in the freezer until final processing. The disadvantage is that such cups made of stainless steel are relatively expensive. For reasons of hygiene and - because of the rotating blade - for safety reasons, the use of such a device in the gastronomy sector, however, only the use of working cups made of stainless steel is permitted. In addition, the opportunities offered by the known device are not exploited by conventional cooks, principally out of awe of the extra work required to prepare soft ice cream or the like. Products to first proactively prepare a block of frozen raw material for stock have to. Moreover, the chefs often lack the knowledge of suitable recipes.

The object of the invention is to remedy this situation. To solve this problem, a cup according to the preamble of claim 1 protection according to the invention provided with the features specified in the characterizing part of the protection claim 1.

In the cup according to the invention, the jacket at the opening in a radially outwardly extending edge for fastening a lid over Ü. A provided in the working cup of the known device below the edge additional shell part, for clamping the working cup in an insulating insert of the known Device is required, is not present in the cup according to the invention. The height of the cup according to the invention substantially corresponds to its nominal filling height plus a supplement of about 10 mm, which takes into account the fact that the cup content during freezing by about 10 mm in height expands. The cup according to the invention is designed as a true disposable cup, which should not be used in the known device, neither in the working cup nor in its insulating insert. The known device should continue to be operated in the catering as usual only with working cups made of stainless steel. The cup of the invention is disassembled to remove the block by hand. The removed from the cup block is then inserted into a working cup of the device for further processing. Essential to the invention is that for this purpose the cup is designed so that it can be easily disassembled by hand. The cup of the invention is cheaper to produce because it does not need to be made of stainless steel. It extends the possibilities of use of the known device, because the starting material block production can take place in a central location, where, in addition, there are sufficiently many recipes. The cup and its contents can be easily accessed via the decentralized device.

Advantageous embodiments of the cup according to the invention form the subject of the dependent claims.

If in one embodiment of the cup according to the invention for the dismantling of the cup at least the jacket with at least one weakening is provided line, at least the coat for removing the frozen block can easily disassemble after the lid has been removed.

In a further embodiment of the cup according to the invention, when a weakening line of the sheath is helically extending between the bottom and the opening, the sheath can be easily unwound from the frozen block after the lid has been removed.

In a further embodiment of the cup according to the invention, if several lines of weakening of the sheath are parallel to the central axis between the bottom and the opening, the cup can easily be widened in the area of the sheath by tearing it open at the lines of weakness, so that the frozen block can be easily removed can be.

If, in another embodiment of the cup according to the invention, a weakening line of the sheath extends at the transition between the sheath and the bottom, the bottom can be separated from the sheath to remove the block. If that is not sufficient to remove the block effortlessly, additional lines of weakness that may be present in the sheath can be used to additionally disassemble the sheath.

If, in a further embodiment of the cup according to the invention, the edge is designed such that it can be welded to a lid, it is ensured, with regard to hygiene regulations, that the cup according to the invention is a disposable cup.

If, in a further embodiment of the cup according to the invention, the cover which can be welded to the edge consists of a plate which can not be detached from the cup after welding to the edge, it should be ensured with greater certainty that the disposable cup is actually used only once becomes.

If in a further embodiment of the cup according to the invention, the jacket at a distance below the edge, preferably in about two-thirds height of the cup, at least one parallel to the bottom line of weakness along which the lid of the adjacent part of the shell together with the lid from the rest Jacket is solvable, it is preferably removed when opening the cup about a third of the same, so that it is guaranteed with even greater certainty that the disposable cup is then actually used only once in consideration of hygiene requirements.

If in a further embodiment of the cup according to the invention, the jacket with distance below the edge, preferably in about two-thirds height of the cup, two parallel to the bottom lines of weakness, which form a tear strip extending over the circumference of the shell, can be preferably effortlessly remove one-third of the cup from the remaining two-thirds.

If, in another embodiment of the cup according to the invention, the tear strip is provided with a tab which can be grasped over the circumference of the shell and can be grasped by the fingers, the opening of the cup is easily possible.

If, in a further embodiment of the cup according to the invention, this has an edge on which the lid can be clipped, the cup can be opened more effortlessly.

If, in a further embodiment of the cup according to the invention, the cup consists of a plastic which is food-safe and cold-resistant, the production of the cup is particularly simple by proven in plastics technology.

If, in another embodiment of the cup according to the invention, the cup consists of a paper or paperboard matehal which is food-safe and cold-resistant, the production of the cup is likewise particularly simple by methods customary in paper technology.

If, in a further embodiment of the cup according to the invention, the bottom and the jacket are designed as separate parts attached to one another, the manufacturability and / or dismantling of the cup can be designed particularly expediently.

If, in one embodiment of the cup according to the invention, the bottom has at least one knob-like depression, the starting material block removed from the cup according to the invention can be inserted into a working cup of the known apparatus, which has at least one matching knob-like depression. In this way, a rotation of the block in the working cup during the crushing of the block can be easily prevented.

If, in a further embodiment of the cup according to the invention, the bottom has three cam-shaped depressions of circular cross-section, the centers of which lie equidistantly on an imaginary circle around the center axis of the cup, the frozen block can be rotationally inserted into a working cup which is complementarily located and formed having knob-like depressions.

In a further embodiment of the cup according to the invention, if the or each knob-like depression has a radial distance from the central axis of the cup which is equal to half the radius of the circular bottom, the maximum resistance to rotation of the block in the working cup can be determined achieve the known device when the knob-like depressions of the working cup are not smaller than that of the cup according to the invention.

If, in a further embodiment of the cup according to the invention, this at least one arranged on the outside of the shell between the bottom of the edge and the bottom radial projection od. Like. To prevent the insertion of the cup in a cup of similar size, it is ensured that the cup according to the invention can not be used intentionally or unintentionally in a conventional working cup of the known device.

If, in a further embodiment of the cup according to the invention, the jacket of the cup widens conically continuously from the bottom to the opening, the block can be easily removed from the cup according to the invention. In particular, it is not necessary to completely disassemble the jacket of the cup in order to remove the block can.

Embodiments of the invention will be described in more detail below with reference to the accompanying drawings. It shows

Invention, which are designated in FIG. 1 with purple or IMb,

Fig. 4 is a longitudinal sectional view of a second embodiment of the cup according to the invention, which here preferably consists of paper or cardboard material, and Fig. 5 in side view a third embodiment of the cup according to the invention.

1 and 2 show in side view and in plan view, designated generally by 10, a first embodiment of a cup 10 according to the invention, which is od for the production and shipment of a block frozen by a soft tea mixture. The like. Is determined. The cup 10 has a circular bottom 12, through the center of which extends a central axis 14 of the cup. Extending from the bottom 12 to an opening 16 of the cup 10 is a continuously conically expanding almond 18. The frozen in the cup 10 and shipped for starting material block (not shown) is intended to be in a working cup of a known device of the above mentioned type to be used for further processing. The inner contour of the cup 10 and thus the outer contour of the block should therefore substantially correspond to the inner contour of such a working cup. If the considered working cup has a cylindrical inner contour, the cup 10 should also be formed, so instead of the flared shell 18 have a cylindrical shell.

At the upper end of the cup 10, the jacket 18 at the opening 16 extends into a radially outwardly extending, flange-like, planar edge 20. The rim 20 is for fastening a cover 22 (not shown in FIGS. 1 and 2) certainly. The edge 20 is designed so that it is welded to a cover 22 forming film 22 'made of metal or plastic (not shown in Fig. 2), as od yogurt cups. Like. Is common. The upper annular surface of the rim 20 has for this purpose a special design or coating which ensures the production of a suitable welding, sealing or bonding.

The cup 10 according to the invention is generally designed so that it can be disassembled to remove the block by hand. By the term "separable by hand" is meant in particular a disassembly without the aid of a tool. availability of the cup 10 at least the jacket 18 is provided with at least one line of weakness 24 or 26, as indicated in Fig. 1. The line of weakness 24 of the jacket 18 extends helically between the bottom 12 and the opening 16. In Fig. 3b an enlarged detail of the cup 10 is shown, which is designated in Fig. 1 with IMb. In Fig. 3b it can be seen that the line of weakness 24 of the jacket 18 is formed as a V-shaped groove 28. Where the groove 28 extends, the shell of the cup 18 is easily divisible by hand. However, the arrangement and the formation of the groove 28 are made so that the cup 10 in the initial state has sufficient for the production of the frozen starting mixture and for the shipment of the frozen starting mixture block strength and rigidity. The same applies to the choice of material from which the bottom 12 and the jacket 18 are made. In the cup 10 described herein, the material selected may be plastic as in a conventional yoghurt cup or the like. Instead of or in addition to the helical weakening line 24, the sheath 18 may have weakening lines 26 parallel to the central axis 14 of the cup 10 extend. The lines of weakness 26, like the line of weakness 24, may consist of grooves V-shaped in cross-section, such as the groove 28. The lines of weakness 24 and 26 also extend to the underside of the rim 20, so that this as well as the rest of the jacket 18 is easily divisible by hand. The lines of weakness 26 extend, like the line of weakness 24, between the bottom 12 and the opening 16 of the cup 10. Usually, the bottom 12 for removing the frozen block does not need to be disassembled as well. It is therefore usually sufficient to let a line of weakness 30 of the jacket 18 run at the transition between the jacket 18 and the bottom 12. Fig. 3a shows an enlarged detail of the cup 10, which is designated in Fig. 1 with purple. According to Fig. 3a, the wall of the jacket 18 may be formed at the transition to the bottom 12 in cross-section V-shaped. Instead, a V-shaped groove such as the groove 28 could be formed at the junction between the shell 18 and the bottom 12 to form the line of weakness 30. Suitably, any food grade plastic is of suitable strength for the production of the cup 10. Instead or in addition, the cup may also be made of food grade paper or cardboard material. A second embodiment of a cup of paper or paperboard material, generally designated 40, according to the invention is shown in FIG. In the cup 40, a bottom 12 'and a jacket 18' are formed as juxtaposed, separate parts which are tightly connected to each other in the use of the cup 40, z. B. by gluing or welding. The jacket 18 'does not terminate in the region of the opening 16 in a flange-like, flat edge, but is rolled in at the upper edge, so that a cover 22' can be clipped onto the cup 40. Accordingly, to fix the bottom 12 'to the casing 18', the latter may be curled inwards at the lower edge, as shown.

The bottom 12 and the bottom 12 'each have at least one knob-like depression. In the illustrated embodiment, there are three knob-like depressions 32, 33 and 34. The knob-like depressions 32-34 are circular in cross section. Their centers are equidistant on an imaginary circle about the central axis 14 of the cup 10 or 40. The or each knob-like depression has a radial distance r from the central axis 14 of the cup equal to half the radius R of the circular bottom 12 and 12 respectively 'is. The knob-like depressions 32-34 are provided when the block is intended for use in a working cup of a known device of the newer generation, which also has such knob-like depressions.

The cup 10 has a radial projection 36 disposed on the outside of the shell 18 between the underside of the rim 20 and the bottom 12. The projection 36 is intended to prevent the cup 10 from becoming lodged in a working cup or insulator insert, typically the working cup of the known art Device receives, can be introduced. For safety and hygiene reasons, namely, the known device in the gastronomy area should only be operated with a working cup made of stainless steel. The cup 10 according to the invention would also not be suitable for this because its height He corresponds to its nominal filling height plus the above-mentioned surcharge of about 10 mm, so that above the nominal filling level plus the supplement in the cup no space is available in which the rotating blade od. Like. Of the known device could be used. Instead of the flange-like, planar projection 36, the cup on the jacket 18 'od with radially outwardly projecting protrusions. The like. Be provided. This solution is suitable for the cup 40, which consists of paper or cardboard material.

The cup 10 is made of plastic by conventional methods, for. B. by injection molding or deep drawing. In contrast, the cup 40 is made as a cup usually used for hot drinks such as coffee or the like. B. by winding the jacket 18 ', in the subsequently the bottom 12' is introduced from above to be connected to the jacket 18 'inside tightly. The bottom 12 'of the cup 40 has the same knob-like downwardly projecting recesses as the wells 32-34 of the cup 10, and therefore these recesses need not be described again with respect to the cup 40.

Further, the cup 40 may be provided with the same lines of weakness 24 and / or 26 as the cup 10 to facilitate disassembly of the cup 40. In paper or paperboard material, the lines of weakness would not consist of grooves of V-shaped cross-section, but would suitably consist of "perforations" which do not extend completely through the wall of the jacket 18 'or the bottom 12. These would, in other words, have the shape of lines formed of punctiform pits not entirely penetrating the material.

Fig. 5 shows a side view of a third embodiment of the generally designated 10 cup according to the invention, which is also preferably made of plastic as the first embodiment of FIGS. 1 and 2. In the cup 10 of FIG. 5, but with the Edge 20 weldable cover 22 not from a film 22 ', but from a plate 22 ", which after the welding with the edge 20 non-destructive of the cup 10 solving bar is. The plate may for example consist of the same material as the rest of the cup, but preferably has a precaution, a slightly greater thickness than the rest of the cup. It should in any case be ensured that the plate 22 "after being welded to the edge can no longer be detached from the edge, even when using suitable tools, without destroying the cup at this point Fig. 5, the jacket 18 below the edge 20 in about two-thirds height of the cup 10 at least one parallel to the bottom 12 line of weakness 27a, along which the cover 22 adjacent part of the shell 18 together with the cover 22 "of the rest of the jacket 18 is solvable. For ease of loosening, in the embodiment shown in Fig. 5, the sheath 18 has about two-thirds height of the cup 10 below the edge 20 two parallel to the bottom 12 lines of weakness 27a, 27b, extending over the circumference of the shell 18 tear strip 27 form. The tear strip 27 is provided with a tab 29 which protrudes beyond the circumference of the jacket 18 and can be grasped by the fingers. Below the tab 29, the jacket 18 is closed along the lines of weakness 27a, 27b, as long as it is not pulled strongly on the tab 29. The weakening lines 27a, 27b may be formed as the weakening lines 24 or 30 of FIGS. 3b and 3a, respectively. If, with the aid of the tear strip 27, the upper part of the cup 10 together with the lid 22 has been detached from the remaining part of the cup 10, the remaining part of the cup 10 is so low in height that it is no longer suitable for the here intended purpose can be used. In the embodiment of the cup 10 of FIG. 5 is best ensured that the cup 10 is actually used as a disposable cup, so only once, so that compliance with the hygiene requirements is guaranteed.
