STORAGE RECEPTACLE FOR PAPERS AND THE LIKE

Abstract: The present invention relates to a group storage receptacles for paper, plastic folders or the like, the receptacle including a bottom (3), a front (2) and a rear wall as well as two opposing side walls (1) and a top opening. Each of the side walls (1) has one or more openings (8-12) extending from the bottom (3) and upwards, these openings being adapted such that side wall parts (4-7, 13-14) are left between them, the bottom (3) having along the bottom-most part of the side openings recesses (8'-12') directed inwards in the plane of the bottom, the depth of each recess attaining to at least the thickness of the side wall (1) and its length along the bottom corresponding to the bottom-most extension of the opening (8-12). By implementing the storage receptacles with different widths, stacking two or more receptacles one in the other is enabled.

Description: Storage receptacle for papers and the like The present invention relates to a storage receptacle for papers or sheet material, e.g. boxes for collecting periodical journals, letter baskets and the like. To reduce space requirements when transporting and storing such receptacles when empty, it is already known to push the receptacles into each other in pairs, e.g. according to the prior art illustrated in the European Patent 066 561. The present invention has the object of providing storage receptacles implemented such that two or more receptacles can be pushed into each other within approximately the same volume as is normally required for a single receptacle. In addition, there is achieved with the aid of the invention a very cheap receptacle, since the tool for producing it can be made very simply without any laterally movable tool jaws. The intended object is achieved in a very simple way by the invention being given the distinguishing features disclosed in the accompanying claims. The invention will now be described in more detail in connection with some embodiments of the storage receptacle illustrated here as examples of a periodical journal collector and in connection with the accompanying drawings, where Fig. 1 is a perspective view of a periodical journal collector in accordance with the invention, Fig. 2 is a view from above of the collector in Fig. 1, Fig. 3 is a view from below of the collector in Fig. 1, Fig. 4 is a group of the collectors stacked one in the other, Fig. 5 illustrates the smallest collector of those in Fig. 4, as seen in a direction of the arrow V in Fig. 4, Fig. 6-7 illustrate the front of the two larger collectors shown in Fig. 4 and Fig. 8-10 are perspective views of further periodical journal collectors in accordance with the invention. In Fig. 1 there is shown a periodical journal collector, where 1 denotes the right side wall thereof, 2 denotes its front wall, 3 the bottom, while 4,5,6 and 7 denote four strips or bars delimiting openings 8 - 12. The side wall 1 has a wider part 13 closest to the front wall 2 and a similarly wide part 14 closest to the lower rear wall of the collector. In the upper part of the front wall 2 there are apertures 15 and 16 for facilitating removal of the collector from such as a bookshelf. It will also be seen from Fig. 1 that between the parts 13,4,5,6,7 and 14 of the side wall there are recesses 8' ,9' ,10' ,11' and 12' where their depth in the plane of the bottom corresponds at least to the thickness of each of the parts 4 - 7 and 13 - 14. In addition, from Fig. 1 it can be seen that the front wall 2 has a lesser width 17 along its middle part for a distance corresponding to the openings 18 in both side walls, so that the edges of this narrower width 17 are somewhat spaced from the plane of the inner surface of the side wall 1. The different strips or bars 4,5,6 and 7 are inclined at an angle 19 to the front wall 2 of the collector and have their delimiting edges substantially parallell. The described embodiment of the collector enables the use of production means not needing to employ moving parts. The inner part or "half" of a tool for moulding the collector forms the inner surfaces of it, and the outer half of it has wide parts forming the openings 8 - 12 and 18 by direct engagement against the inner half. These parts are defined by parallell edges, although these edges can have a certain amount of rake to facilitate pulling off at the angle 19 to the front of the collector, this angle being that at which the openings 8 - 12 and bars 4 - 7 are placed. Both tool halves can thus be entirely without moving parts. The apertures 15 and 16 can also be made in this tool, although they will have somewhat sloping edges, which does not have any importance for their function. Fig. 2 illustrates the collector from above with the right hand side wall 1 in Fig. 1, its opposing side wall 1' and front wall 2. The back wall 20 of the collector is also shown, this wall sloping at the same angle 19 as that of the openings 8 - 12 and bars 4 - 7, which is best seen by the sloping rear edge in Fig. 1. Fig. 3 illustrates the collector seen directly from below, and the denotations in said Fig. 3 are the same as have been used earlier. There are apertures 21 in the bottom. Such apertures decrease the weight of the material required for the collector, which of course also results in its having a lower cost. Fig. 4 illustrates a group of three collectors, denoted by 22,23,24, which are stacked one inside the other. They are similarly implemented, with the sole essential distinction that the widths 25,26 and 27 of the collectors increase from the collector 22 to the collector 24, see Fig. 5 - 7. The difference in width is approximately twice the wall thickness of the collector on the outside. Of course, more or less than three collectors can be implemented such that they can be thrust one into the other. The fact that the collectors that can be stacked one inside the other have somewhat different widths lacks any great importance in practice, since it is more a question of appearance when the collectorsare placed side by side on a shelf, for example. The difference between two such collectors is so small that it is hardly spontaneously observed. Fig. 5 is a view in the direction of the arrow V in Fig. 4 of the smallest of the collectors in Fig. 4, and the outside width of the collector is denoted by 25. Fig. 6 illustrates the middle one of the collectors in Fig. 4 seen from the front, and with its outside width being denoted by the numeral 26. Fig. 7 illustrates in the same way as Fig. 6 the largest of the collectors, with its outside width denoted by 27. Fig. 8 illustrates a collector 28 of the same principle embodiment as the one in Fig. 1. In this case the collector 28 has three strips or bars 29,30,31 and an aperture 32, the latter being a finger grip for removing the collector from a shelf. This aperture can also be achieved with the aid of a tool not having moving parts. Fig. 8 also illustrates the recesses 33,34,35 and 36 made in the plane of the collector bottom. Fig. 9 illustrates a collector 37 with an embodiment including a front higher part 38 and a rear lower part 39. Both parts each have two side openings having recesses 38,39,40,and 41 in the plane of the bottom, and made by the outstanding parts of the outside half of the tool. Fig. 10 illustrates a periodical journal collector 42 with a different appearance, primarily with regard to the implementation of its side walls, which have openings 43 with curved defining edges 44, both ends of which extend to the bottom of the collector and have a configuration such that the front and rear tangents 45,46 to the curved line at the bottom are parallell to the defining edge 47 of an opening 48 in each side wall of the collector and adjacent its front wall. All these lines 45,46 and 47 have the same angle 49 to the front wall of the collector 42, with the object of enabling the tool forming the openings 43 to open in the direction determined by the angle 49 when the collector is ready-moulded in the tool. Fig. 10 also shows a long recess 50 in the plane of the bottom of the collector between the edges of the opening 43 at the tengents 45 and 46. The side opening 43 can also be given a shape such that its tangents 45 and 46 converge, i.e. they have an intersection point above the bottom of the collector. The releasing angles in the injection moulding tool will thus be greater and the ready-moulded collector is easier to remove from the tool. It is also obvious that the angle 51 for the upper defining edge of the side wall must not be greater than the angle 49. It will be clearly understood that in the same way as a single collector can be produced in a tool with a single moulding cavity, a tool without any moving parts can be formed with such as three moulding cavities with somewhat different sizes, so that the three collectors 22 - 24 illustrated in Fig. 4 can be produced simultaneously in the tool. This contributes further to reducing the costs of producing the periodical journal collectors. The embodiments of the invention which have been described above can be varied by one skilled in the art, and given different embodiments without departing from the inventive concept disclosed in the claims.
