Definitions

• the invention relates to a collapsible transport receptacle which in the put-up functional state essentially has the form of a parallelepipedal box with a plane bottom, two long walls, two end walls and four corners.
• Collapsible transport receptacles are previously known. For example, reference can be made to GB 2 147 276 and EP 0 048 577.
• the collapsible containers which are describ in these patent specifications are designed in order to satisfy the demands which are made on large containers for sea transport.
• Non of these known transport receptacles however, satisfy the demands which are made on receptacles for transport and storage of certain foodstuffs, for example meat, over shorter distances, for example between slaughterhouse and cooked-meat factory.
• the purpose of the invention is to make available a new transport receptacle which is collapsible and which satisfies the demands which are made on receptacles for handling foodstuffs, including meat and cooked-meat products.
• the desires and/or demands which the invention aims to be capable of satisfying the following may be mentioned.
• the receptacle is to have such a construction that it can be manufactured completely from stainless steel, which does not, however, preclude even other construction material also being possible, at least for certain areas of application for example lacquered non-stainless steel, aluminium etc.
• the receptacle is moreover to have such a construction that it can be approved for handling foodstuffs, including meat and cooked-meat products, which inter alia means that it is to be capable of being cleaned easily, which in turn means that it must not have any open pockets or other surfaces which are concealed or of difficult access. It is to be suitable for use of an inner bag made of plastic for the products which are to be handled, which means that the receptacle should have soft edges and be free of sharp corners or pointed projecting parts.
• the receptacle is to be stackable, both in the functional state and in the handling state.
• the receptacle is to be capable of being handled with the aid of fork-lift trucks both in the functional state and in the collapsed state and have space for truck forks under and between receptacles both in the functional state and in the collapsed state. -
• the receptacle is to be robust.
• the receptacle is to have minimal height in the collapsed state.
• Fig. 1 represents a perspective view of the receptacle in the functional state
• Fig. 2 represents a perspective view of the receptacle with the end walls folded in against the insides of the long walls
• Fig. 3 shows the inside of an end wall and parts of the insides of the long walls and the bottom in a perspective view of the receptacle in the functional state
• Fig. 4 shows a corner part with an end wall which is folded in against a long wall
• Fig. 5 represents a perspective view of the receptacle in the collapsed state
• Fig. 6 shows a part of the collapsed receptacle in a view VI- VI in Fig. 5.
• the transport receptacle 1 has in the put-up functional state, Fig. 1, essentially the form of a parallelepipedal box with a plane bottom 2, two long walls 3 a, 3b, two end walls 4a, 4b and four corners 5a-d. All components according to the embodiment consist of stainless steel.
• the bottom 2 consists of a plane stainless bottom plate 6 which at all four edges is bent round to form on the underside tight-welded edge beams 7 with square cross-section. Situated centrally on the underside is a transverse reinforcing U-beam.
• Each long wall 3a, 3b is formed by a plane sheet-metal panel 10 with an upper, inwardly and downwardly turned bead 11 and a lower bead 12 formed in corresponding manner which is turned inwardly, upwardly and outwardly.
• Both the beads 11, 12 have in cross- section a generally rounded shape and are tight-welded to the inside of the sheet-metal panel 10. They extend along the entire length of the long walls 3 a, 3b and are at the ends tight-welded to a flange 13 which is turned inwardly at right angles and which extends along the entire height of the long walls 3 a, 3b between said upper and lower bead 11, 12.
• a recess 14 Between on the one hand said upper and lower beads 11, 12 and on the other hand the two side flanges 13, there is thus formed on the insides of the two long walls 3a, 3b a recess 14.
• each long wall 3a, 3b has a post 16 which extends up at right angles from the upper bead 11, Fig. 6.
• the post 16 has in cross-section the general shape of a right- angled triangle, one cathetus side of which constitutes a continuation of the flange 13, while the other cathetus side lies in a plane with the sheet-metal panel 10.
• the height of the long walls 3a, 3b plus the height of the post 16 corresponds almost to the width of the bottom 2 of the receptacle, Fig. 5.
• catches 18 which are bent at right angles and which form an element in first hinge members for rotating the end walls 4a, 4b in the corners 5a, 5c when the long walls 3a, 3b are put up.
• the two catches 18 in the two corners 5a, 5c extend with a leg at right angles in from the flange 13 into the corners 5a, 5c and subsequently, after the knee of the catch, with a leg at right angles to the inside of the sheet-metal panel 10.
• the two catches 18 are fixed to the flange 13 and to the panel 10 by welding.
• each of the two side flanges 13 of the long walls 3a, 3b there are on the one hand, at the very bottom, that is to say in the region of the lower bead 12, an outwardly directed hinge pin 15, and on the other hand, a little above the hinge pin 15, an outwardly directed fixing pin 17.
• Each end wall 4a, 4b has, in the same manner as the two long walls, a sheet-metal panel 20 with an upper longitudinal bead 21, a lower longitudinal bead 22 and, at each end, an inwardly turned flange 23.
• each sheet-metal panel 20 In the region of said first, diagonally opposite corners 5a, 5c, there is in each sheet-metal panel 20 a punched-out L-shaped slot 25. These two slots 25 are positioned for interaction with the two catches 18.
• the slots 25 are of identical design and have a vertical part 26, the height of which corresponds to the height of the lower bead 12 on the respective long wall 3a, 3b.
• the horizontal leg 27 on said L forms, together with the respective catch 1 S, a hinge which will be explained below.
• the respective sheet-metal panels 20 of the two end walls have a vertical slot 28 close to the flange 23 in the region of the two other corners 5b, 5d, when the receptacle 1 is in the functional state, which slot 28 is positioned for interaction with the respective hook 19 on the long walls 3a, 3b.
• the total height of the end walls 4a, 4b corresponds essentially to the height of the recess 14 in the respective long wall 3a, 3b, that is to say the distance between the upper side of the lower bead 12 and the underside of the upper bead 11, so that the end walls 4a, 4b can be folded into the recess 14 in the respective long wall 3a, 3b when the receptacle 1 is to be folded up into the collapsed state.
• corner element 30a In the two first diagonally opposite corners 5a, 5c, there is a corner element generally designated 30a and in the two other, diagonally opposite corners 5b, 5d there is a corner element generally designated 30b.
• the corner elements 30a and 30b constitute mirror images of one another but are otherwise of identical design. They are made from a stron metal sheet which is bent into an angle. A lower part is somewhat projecting and forms a leg 31. The remainder, which in this text is called a corner upright 32 but which is itself integrated with the leg 31 , extends up vertically from the leg 31 a way essentially corresponding to the length of the leg 31 and past the collapsed walls when the receptacle 1 is collapsed, Fig. 4.
• the corner elements 30a, 30b are welded firmly to the edge beams 7 of the receptacle bottom 2.
• a vertical slot 34 which i at least as long as and preferably somewhat longer than the combined thickness of the collapsed walls.
• the hinge pin 15 extends out through this slot 34.
• a cutout 35 which can accommodate with fit the respective fixing pin 17.
• a sliding surface 36 which extends from the edge of the leg 33 up towards the cutout 35.
• the legs 31 have a length which is sufficient in order that the forks on a normal fork-lift truck will be capable of being guided in under the lower edge beams 7 of the receptacle bottom when the receptacle 1 is standing on a plane base.
• the receptacles 1 are furthermore stackable both in the functional state and in the collapsed state. In the former state, one receptacle 1 can be placed on another receptacle 1 by the legs 31 on the upper receptacle being lowered over the corner posts 16 on the lower receptacle, the 'corner posts 16 forming male members and the legs 31 forming female members in the joint between the receptacles thus brought together.
• the corner posts 16 have in this case a length essentially corresponding to the length of the legs 31.
• the forks of a fork-lift truck can be guided in under and between the receptacles stacked one on another.
• the method is as follows.
• the receptacle 1 is in functional state according to Fig. 1.
• the two end walls 4a, 4b are lifted up as far as the vertical part 26 in the L-shaped slots 25 allows, the catches 18 running in said slots 25.
• the end walls 4a, 4b have thus been lifted to the maximum, they are rotated in towards the respective long wall 3a, 3b, the end walls 4a, 4b sliding on the catches 18 in the horizontal parts 27 of the slots 25 so that the end walls 4a, 4b describe a rotary movement about vertical axes of rotation in the two first, diagonally opposite corners 5a and 5c.
• the end walls 4a, 4b are thus, by rotation in said first hinge members 18, 27, folded into said recess 14 in the respective long wall 3a, 3b so that the upper bead 21 of each end wall comes to lie under the upper bead 11 of the associated long wall and the lower bead 22 of each end wall comes to lie above the lower bead 12 of the associated long wall.
• the method is the following. First, the upper of the long walls 3a, 3b lying one on another is erected, the two hinge pins 15 of this long wall being rotated in the slots 34. Towards the end of this movement, the fixing pins 17 will slide on the respective sliding surface 36 to finally drop "down into the cutout 35 when the long wall has assumed the vertical position.
• the hinge pins 15 move in a corresponding manner vertically in the vertical slots 34.
• the second long wall with end wall folded into it is lifted up and fixed in the same manner.
• the two end walls 4a, 4b are rotated out of their folded-in positions in the respective recess 14 of the long walls, first sliding on the catches 18.
• the end walls drop down, the vertical parts of the L-shaped slots being lowered by relative movement in relation to the catches 18.
• the cutouts 24 in the lower corner of the end walls 4a, 4b drop down on the lower beads 12 of the long walls, it being possible to fix the end walls by the respective hook 19 being brought into engagement in the associated slot 28.
