DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a process and device for opening, emptying and flattening in a single operation hermetically closed, preferably cylindrical, metal or composite containers.
It is known that the opening of this type of containers, in particular preserved food cans, is traditionally effected by cutting one of the bottoms or lids around the formed-over rims, which is slow and dangerous, since the edges of the lids or of the formed-over rims become sharp and there is a risk of injuring the operator.
Further, the empty containers which become bulky are, up to the present time, discharged, either by voluminous garbage bins or containers, or taken for the purpose of crushing them in waste product presses or crushers which are expensive and require handlings, time and energy.
SUMMARY OF THE INVENTION
The object of the present invention is to eliminate these drawbacks by proposing a process and a device whereby it is possible to carry out in a single operation, the opening, the emptying and the flattening of the containers with no risk of injury to the user, this device being capable of being used by individuals, craftsmen, industrials and collectivities such as restaurants.
According to the invention, the process is characterised in that the containers are partly severed in the median zone of their bodies by leaving between their two halves a retaining strip, these two halves are deformed while opening them downwardly so as to empty them before flattening them, and the crushed containers are ejected after their contents are received in a receptacle.e
Thus, contrary to that which was carried out up to the present time, the invention provides for the opening of the containers, no longer by one of their bottoms, but by the median zone of their body.
According to the invention, the device for carrying out this process is characterised in that it comprises, mounted in a fixed support frame: vertical and convergent inclined planes and opening onto this opening; example a chute so that each container can bear in succession by its ends on the inclined walls of the hopper and above said opening; mounted in the frame in such manner as to be movable against the successive containers and equipped with driving means, the cutter having a contour adaptable to the diameter of the containers, and being positioned in such manner as to partly sever the latter transversely in the median zone of their body; severing by the cutter while producing their emptying into a receptacle placed under the hopper.
Thus, as the cutter or cutters for severing the containers move inside the frame of the device out of reach of the user, any risk of injury to the latter is avoided.
Further, the flattening or crushing of the containers following on their emptying is carried out with no particular handling and no risk of accident for the user.
Lastly, the flattening of the containers after their emptying solves the problems of bulkiness encountered up to the present time while avoiding the necessity of, as the case may be, costly crushers or scrap presses.
Other features and advantages of the invention will be apparent from the following description with reference to the accompanying drawings which illustrate by way of non-limiting examples several embodiments thereof.
FIG. 1 is a diagrammatic side elevational view of an embodiment of the device according to the invention for opening, emptying and flattening containers;
FIG. 2 is a cross-sectional view taken on line II--II of FIG. 1;
FIG. 3 is an elevational view of the device in a plane perpendicular to that of FIG. 1;
FIGS. 4-4F and 5-5F are diagrammatic elevational views respectively in two perpendicular planes of a sequence of opening, emptying, crushing and ejection of a container by means of the device of FIGS. 1 to 3;
