Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a compactor, or crushing device, for compressible containers, in particular in plastic, in metal or in cardboard.

2. Description of Related Art

The compactor according to the invention can advantageously, but not only, be intended for domestic use and can thus constitute a particularly practical utensil within reach of the housewife.

It is known that the use of plastic bottles has come into general use, as well as the use of metal tins (“cans”) for drinks. Once empty, these containers are bulky and it is therefore often necessary to decrease their volume. Different compactors exist for this purpose, nevertheless having various disadvantages.

The former state-of-the-art is in particular represented by the patent documents U.S. Pat. No. 3,009,414, FR-A-2689034, FR-A-2750073, EP-A-0554646, JP 9234597 and U.S. Pat. No. 5,765,473.

SUMMARY OF THE INVENTION

The purpose of this invention is to put forward a simpler and nevertheless more efficient, lighter, more compact and stronger compactor, essentially for containers intended for liquids. This operation causes the crushing of all containers placed between the two elements.

According to the invention a compactor is indeed put forward consisting of a fixed frame and a mobile element, integral with the frame but capable of sliding through a part of the fixed frame. In its extend or open form, the compactor can receive a container between the upper part of the fixed element, playing the role of an anvil and an upper part of the mobile element playing the role of a plunger piston. The mobile element is then subjected to a downward vertical force, this force is applied to its lower part, present below the upper part of the fixed element. The container is thus compressed between the two upper parts, between their opposites surfaces, by a force exerted downward in a point located at the lower part of the sliding mobile element, located above the lower part of the fixed element.

The force on this mobile part is advantageously exerted by the user's foot, the fixed frame being placed on the floor.

The principle on which an aspect of this invention rests, consists in compressing a container by exerting a force with the foot, and therefore potentially with the weight of the user's body, the foot being situated below the container and exerting its force on a stirrup or a pedal comprising at least one arm directly connected to the mobile compressor element located above the container, the arm(s) sliding in a fixed frame on which the aforesaid container is placed.

The sliding part comprises an upper compressor element, for example in the form of a plate or a ring, capable of vertically compressing the container. This element can more or less partially conform in shape to the upper part of the container in order to maintain the vertical stability of this during the compression. The annular element of the plate can thus advantageously have an opening capable of receiving the neck of a plastic bottle.

The upper compressor element is connected, preferably rigidly, to a lower bearing plate, playing the role of pedal.

The connection can be effected by one or several arms in the form of rods or tubes sliding in an upper part of the fixed frame, the aforesaid frame being at least partially open and housing the bearing element on which the compression force is exerted. The rods or tubes can be metallic.

Advantageously the connection can also result from a lateral part of a cylindrical wall sliding on an additional lateral part of the fixed frame.

The frame or fixed part contains the bearing element and is capable of containing it during its stroke at the time of the compression operation. The fixed frame has a lateral recess capable of enabling the foot to exert its force during the entire stroke of the sliding element. The frame advantageously comprises a base for providing its stability on the floor.

The fixed frame can be implemented in rigid plastic, for example in the form of two identical, molded and assembled, half body shells possibly having internal reinforcement ribs. According to one embodiment, these assembled half bodies can contain lateral internal guides, for example in the form of channels or grooves, in order to enable an easy sliding of the tubes or rods of the sliding part connecting the compression plate and the pedal.

DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 a is a cross-sectional elevation drawing of a compactor according to one embodiment of the invention.

FIG. 1 b is a cross-sectional top view.

As appears from these figures, the plastic bottle compactor consists of a tubular body 1 whose base 11 is placed on the floor, the upper part 5 is at least partly enclosed. The lateral cylindrical wall has an elliptic vertical long opening cut-out 3 extending laterally to approximately half the cylindrical wall, enabling the insertion and the downward thrust of the front part of the user's foot.

Around the tubular body 1 slides the tubular body partially closed on top 2 , its lateral cylindrical wall also has an elliptic vertical long opening cut-out 4 similar and complementary to the opening of the tubular body 1 .

The uncapped bottle 12 is engaged upright in the opening 4 by raising the tubular body 2 by hand, the neck capable of partially engaging in the upper part 5 provided with an appropriate opening 8 .

This opening 4 also receives the foot 8 in its lower part right below the upper part 7 of the cylindrical body

The vertical thrust exerted by the foot on the cut-out lower edge 9 of the cylindrical wall of the tubular body 2 makes this descend and thus compresses the bottle between the opposite surfaces of the upper part 5 and of the top upper part of the tubular body 1 and the bottom of the upper part of the tubular body 2 .

The upper base of the tubular body 2 is provided with a circular opening 6 that centers the neck of the bottle during the crushing and enables the previously removed cap to be replaced, which still improves the result of the crushing.

FIGS. 4 a and 4 b illustrate the crushing operation of a bottle with a compactor that constitutes a variant of the invention. The element 41 is no longer a tubular body but constitutes a vertical upright on which a second vertical upright 42 slides, the two extremities of the uprights 41 , 42 being provided with perpendicular elements capable of wedging a container between the upper element 47 of the fixer upright 41 and an upper element 45 of the sliding upright 42 . The downward sliding of the upright 42 results from the pressure of the foot 8 on the element 49 forming a pedal and causes the crushing of the bottle 12 .

FIG. 5 illustrates yet another embodiment of the invention, the sliding parts 51 and 52 essentially being formed of metallic rods or tubes. The sliding element 52 consists of 3 parallel tubes 80 , bent at the extremities and connecting an upper ring 55 and a lower pedal 59 . The tubes slide through an upper plate 57 that is itself connected by 4 rigid parallel rods 81 to a base 511 thus together forming the fixed frame 51 . The container is compressed between the ring 55 and the upper surface of the plate 57 that forms an anvil.

FIG. 6 represents yet another embodiment of the invention. The frame 61 is a rectangular structure disposed on a bare 611 . In this structure two tubes 80 slide in guiding channels 84 provided opposite in the uprights 85 . These tubes connect the ring 68 and the pedal 69 . A hollow 67 ′ in the upper surface 67 of the fixed frame can be seen, capable of better conforming in shape to the bottom of the container to be compacted. The third rod 80 ′ of the sliding part of the compactor has the characteristic of being outwardly recessed at its lower part 83 so as to enable a deeper insertion of the sole of the user's foot.

FIGS. 7 a and 7 b illustrate a particularly advantageous embodiment for manufacturing a compactor according to FIG. 6 . It will indeed be noted that the fixed frame can consist of two identical injection molded pieces 71 and 71 ′ assembled with screws in 91 , parts 92 projecting with a piece that moreover adapts to openings 93 on the complementary piece and vice versa.

FIGS. 8 a and 8 b illustrate the stirrup-shaped pedal similar to that represented by 69 in FIG. 6 a , viewed respectively from above and from below.

The rest of the compactor consists of metallic elements (ring and bent rods) that can easily be mounted, for example by clipping together, prior to final assembly of the half body shells 71 and 71 ′, in the seatings 84 , 95 , 96 provided on the frame and the pedal as experts will understand.

It is obvious that numerous variations in details can be provided in the scope of the invention, the protection sought only being limited by the formulation of the claims.

Thus, for example, the compactor could be provided in order to receive a bottle in inversed position, in other words neck downward, which can be advantageous for certain applications (complete emptying of the content of the container).

It will also be understood that the invention more generally reveals a compression device for compressible material comprising two elements, e.g. vertical tubular bodies sliding into one another, the upper element being at least partially closed at its two extremities and the lower element being at least partially closed at its upper extremity, the aforesaid elements each having at least one lateral recess enabling on the one hand the insertion of the compressible material in the upper element extended by sliding and on the other hand the sole of a foot on the lower extremity of the aforesaid upper element sliding in or around the fixed lower element.
