Description
The invention relates to a chopper with an upper part, a lower part detachably fastened to the upper part as well as an axially displaceable actuation part connected to at least one blade.
2. Diccussing of the Related Art
A prior art chopper of the aforementioned type has a drawback in that after the chopping process the chopped food lies on a supporting surface and, if not all the chopped food is used for cooking, must be put into a container. Moreover, when the lower part is lifted from the supporting surface, the chopped food removes itself from the lower part and must be put under the lower part again to continue chopping.
SUMMARY OF THE INVENTION An object of the present invention is to improve the Prior art chopper in such a way that the mentioned drawbacks are avoided. This object is achieved according to the invention in that the lower part is provided with a removable chopping cup or with a floor. The invention also relates to a chopping cup for a chopper.
BRIEF DESCRIPTION OF THE DRAWINGS Preferred embodiments and of the invention, as well as their application, will be described more closely in the following, with reference to the accompanying drawing in which:
FIG. 1 is a view of a first embodiment of the chopper, partially in section;
FIG. 2 is a sectional view of the chopping cup with a lid placed thereon;
FIG. 3 shows the lower part and part of the upper part of the chopper according to a second embodiment;
FIG. 4 is a perspective view of the lower part and of the chopping cup of a third embodiment; and
FIG. 5 is a section through the lower part and the chopping cup according to FIG. 4.
DESCRIPTION OF THE PREFERRED EMBODIMENTS The chopper 1, for example for chopping vegetables, according to the embodiment of the invention as shown in FIG. 1, comprises an upper part 2, a cylindrical actuation part 3 axially displaceable therein with a head 4, a blade 5 connected to the part 3, a lower part 6 which can be placed upon the upper part 2, and a chopping cup 7 which can be placed on the lower part 6. By means of grooves 8 in the cylindrical part 3, cylindrical part 3 is led into upper part 2 in such a way that, by pressing down firmly on the head, blade 5 executes an axial movement and a rotating movement. Upper part 2 is designed offset in its lower area 9 for placement of the lower part 6. The lower part 6 ends in a conical part 10 for easier placement of the lower part 6. The lower area 9 is provided with two tabs 11 opposite each other for the purpose of forming a bayonet catch. Lower part 6 is provided with corresponding grooves 12 in its upper area to form the bayonet catch between upper part 2 and lower part 6. Placed on blade 5 is a stripper 13 having an opening corresponding to the blade 15. The stripper 13 has an upper protruding rim 14. The lower edge 15 of the stripper 13 rests on an inwardly protruding projection 16 of lower part 6. The wall of lower part 6 has a step 17 somewhat below the upper rim 14 since stripper 13 and lower area 9 of upper part 2 do not have the same diameter. Lower part 6 is provided with an outwardly projecting fitting rim 18 on its lower end. Chopping cup 7 has a floor 19 having a rim 20 protruding upwardly in its outer area on the outside of lower part 6. Rim 20 is provided with nubs 21 on its inside, which together with the fitting rim 18 form a snap closure. 0n the inside of lower part 6, a cylindrical cup wall 22 extends upwardly from the floor 19. The cup wall 22 extends up to the area of projection 16.
During chopping, the chopped food remains in chopping cup 7. After the chopping process, chopping cup 7 with the chopped food can be removed from lower part 6 of the chopper. With a prior art chopper, when the lower part is lifted from the supporting surface, the chopped food removes itself from the lower part and must be put under the lower part again in order to continue chopping.
Shown in FIG. 2 is chopping cup 7 with lid 23 placed on it. Lid 23 has a wider rim 24 on the outside and disposed, spaced apart therefrom, toward the inside, a narrower rim 25. With the two rims 24 and 25, lid 23 is placed on the cylindrical cup wall 22 of chopping cup 7. The lid has, in addition, a tab 26 to lift it up from the chopping cup. The chopped food which is left over can be kept in the refrigerator in chopping cup 7 with lid 23 placed on.
Shown in FIG. 3 is the lower part 27 and part of the upper part 2 of a second embodiment 28 of the chopper. The upper part 2 is shown drawn broken off, and corresponds to the upper part in the first embodiment. The lower part 27 is shown in section. In the case of the lower part 27 according to this embodiment, the chopping cup is designed integrated with the lower part in that cylindrical lower part 27 is closed off with a floor 29. Lower part 27 likewise has two grooves 30 in the upper area which, together with the two tabs 11 on the upper part 2, form two bayonet closures. Lower part 27 likewise has a projection 31 on which the stripper 13 rests with its lower rim 15. Stripper 13 could be provided with a snap closure cooperating with the lower area of upper part 2 so that when removing lower part 27 the stripper 13 does not remain on the projection 31 itself. Moreover above projection 31 a step 32 is formed since the lower area 9 of the upper part 2 and the stripper 13 do not have the same diameter. With this embodiment too, the chopped food remains gathered together below in the lower part 27 designed as a chopping cup. Lower part 27, filled with the remaining chopped food, can be removed from the upper part, be provided with a lid, similar to that according to FIG. 2, and be preserved in the refrigerator.
In the case of a further embodiment, the lower part has in its lower area not a projection, but rather a thread for detachable fastening of the cup. The rim projecting upward outside on the lower part in the outer area of the floor of the cup does not have nubs, but is provided instead with a thread on the inside.
FIG. 4 shows a lower part 33 of the chopper with screw thread 34 and shows a chopping cup 35 with a rim 36 and screw thread 37. The screw thread 37 is screwed onto the screw thread 34. FIG. 5 is a section through the chopping cup 35 with rim 36, screw thread 37 and floor 38. The chopping cup is to be screwed on the lower part 33 of the chopper.
