Definitions

  • ABSTRACT This invention relates to a container, having a cavity which is surrounded on all sides, comprising a hoodlike top the walls of which end in outwardly projecting flanges and a base plate to the upper surface of which the ,top is fastened with the underside of said flanges, the container in the closed condition having end walls and partial side walls extending downwardly from said top and terminating in said outwardly projecting flanges, the pair of partial side walls bordering on the lateral edges of the same end wall extending parallel to each other in the same direction so that the pairs of partial side walls issuing from different end walls meet upon each other, each pair of partial side walls extending in the same plane having a common pivot point and open edges which form an angle with the upper edges of these partial side walls between about and and the base plate including two flat sections and having an overlapping zone formed by an overlapping arrangement of said two sections, the overlapping edge of the upper section extending vertically beneath a folding line in the top of the container.
  • the present invent relates to a container having a cavity which is surrounded on all sides and can be made accessible, for filling with goods, by flipping the container open, and can be re'closed on hinges after the container has been filled or the goods removed.
  • the container according to the invention can be repeatedly opened and reclosed as often as desired.
  • the present invention relates to a container of the type mentioned in which a molded hollow body forming the container is composed of two components, viz. a molded top and a flat base plate.
  • the top is in the form of a hood and the sides'thereof end in outwardly projecting flanges surrounding it; the top is provided with a hinge.
  • the molded hollow body, and thus the container, is formed by fastening the flanges of the hood-like top to the surface of the base plate in such a manner that a cavity is formed.
  • Containers formed by joining a hood-like molded top with flanges to a flat base plate are known undervthe designations blister packs, bubble packs, and hood packs.
  • the hood-like component of the container consists of a plastic material and the flat base plate is normally made ofcardboard provided on one surface thereof with a heat-sealable layer of polymer material.
  • the hood is separated from the base plate by destroying the sealing bondbetween the base plate and the flanges of the hood. This means that the container is destroyed and cannot be usedagain.
  • the base plate can be removed. This container, too, cannot be closed again once it has been opened.
  • a re-closable hood pack in which the hoodand the base plate can be easily detached and joined again, because the base plate is in the form ofla slide.
  • this known pack two or three side walls of the hood must be bent around in such a manner that. they form rails for holding and guiding the slide plate.
  • this container has the disadvantage that its mechanical strength decreases with increasing size of the container and/or increasing weight of the goods contained therein.
  • the present invention provides a container having a cavity which is surrounded onallsides and. comprising a hood-like top whose sides end in outwardly. projecting flanges and a base plate to the upper. surface of which edges which form an angle between and 160 with the upperedges of the partial side walls.
  • two parallel partial side walls have open edges which forman angle of 90 with their upper edges, whereas the other two partial side walls have open edges which form obtuse angles with their upper edges, preferably angles between 90 and
  • the folding line in the top and the overlapping edge of the overlapping section of the base plate extend parallel to and vertically above each other, and the overlapping section is attached to the flanges of those partial side walls-the open edges of which form right angles'with the upper edges of the top.
  • the base plate consists of two flat sections and has an overlapping zone formed by the overlapping arrange mentof the two sections, the overlapping edge of the upper section extending vertically beneath the folding line in the top of the container.
  • the base plate is a substantially flat surface whose size is determined by the outer edges of the flange of the top. It comprises two planar sections of suitable materialwhich are arranged in such a manner that a narrow overlapping zone is formed.
  • planar; sections forming the base plate of the container advantageously comprise cardboard provided on one surface with a heat-sealable'layer, or of a thermoplastic film having at least one heat-scalable surface. lnthe latter case, it is of particular advantage to also produce the hood from a thermoplastic film.
  • the sides of the top comprise two opposed end walls of identical dimensions and four partial side walls, whose height is substantially the same and corresponds to that of. the end walls.
  • Each partial side wall adjoins the lateraledge of one of the end walls and forms an angle with the end wall.
  • the two partial side walls adjoining the lateral edges of the same: end wall preferably extend parallel to each other and the pairs of partial side walls issuing from. opposed end walls meet each other.
  • the pairs of partial side walls thus extending in opposite directions join to form a continuous side wall of the top.
  • the top of the container has two such continuous side walls which preferably extend parallel to each other at a distance which is determined by the width of the end walls. End walls. and. partial side walls of the container end in flanges which projecthorizontally outwardly.
  • All partialside walls form the same, preferably right, angle with the plane of the ceiling area.
  • the lower edges of the endlwalls and the partial side walls are on thesame level:
  • Anend wall is that wall of the hood-like top which is bounded by twolateral edges.
  • the upper and lower boundaries of the end wall are its upper and lower edges.
  • Anend walli has no open edge.
  • the upper edge of a side of the hood-like top is the line in which: the ceiling area adjoins either one of the end walls or a partial'side wall of the hood;
  • the lower edge of a side of the hood-like top is the line in which either an end wall of a partial side walllborder on the zone of the flange.
  • Apartialside wall is bounded by its upper and lower edges, by anopen edge, and by a lateral edge of an end wall.
  • the open edge of a partial side wall is that edge in v
  • the angle formed by the open edge of a partial side wall and its upper edge is in the range of 90 to 160.
  • two parallel partial side walls have open edges which form an angle of 90 with their upper edges, whereas the other two partial side walls have open edges which form obtuse angles with their upper edges, preferably angles between 90 and 140.
  • each pair of partial side walls i.e., those issuing from the same end wall, form the same angle.
  • the point of the hood-like top in which the open edge and the upper edge of a partial side wall meet will be designated as the pivot point.
  • the top has two pivot points.
  • the connecting line between these two pivot points is called the folding line; it extends parallel to the upper edges of the end walls.
  • the lower edges of the partialside walls of the top extending in the same plane may be 'as long as the corresponding upper edges of the same partial side walls.
  • the open edges of the partial side walls are flush with each other.
  • the lower edges of a pair of parallel partial side walls opposite one another are longer than the upper edges appertaining to the same partial side walls.
  • an embodiment of the top is possible in which all partial side walls are shaped in this manner.
  • the open edge of this side wall extends obliquely downward from the upper edge and forms an obtuse angle with the upper edge. In this case, the openedge ends above the level of the flanges.
  • the open edge of the thus prolonged partial side wall, the vertical line from the pivot point upon the flange, and that edge of the partial side wall which extends from the end of the open edge to the base of the vertical line define an area which is designated as the overlapping area.
  • the lower boundary edge of the overlapping area describes a line which corresponds to an arc.
  • the overlapping zone is thus in the shape of a circular sector whose radius corresponds to the vertical line from the pivot point to the level of the flange and whose center lies in the pivot point.
  • the inner surface of the overlapping area of one partial side wall is substantially in contact with the outer surface of the other partial side wall extending in the same plane, and when the latter partial side wall is also provided with an overlapping area, the outer surface of this overlapping area is substantially in contact with the inner surface of the first-mentioned partial side wall,
  • the overlapping areas of the partial side walls are of such shape that their lower edges describe an arcuate line. This is necessary to facilitate opening and closing of the container.
  • the overlapping area also may end in a straight lower edge.
  • the overlapping area is in the shape of an isosceles triangle whose legs are the vertical line issuing from the pivot point and the open edge of the partial side wall. Consequently, the angle between the vertical line from the pivot point and the straight-lined lower edge must be the smaller, the greater the angle between the open edge of the overlapping area and the upper edge of the side wall.
  • the hood-like top may comprise any material that is of sufficient inherent stability, resiliency and flexibility; most advantageously, it consists of plastic material.
  • the hood-like top consists of a thermoplastic film of the above-mentioned characteristics and is manufactured by the thermoforming method.
  • Thermoplastic films of modified polystyrene, of polyolefins, and in particular of polyvinyl chloride are preferred.
  • Particularly advantageous for the manufacture of the top is a transparent, tough film based on polyvinyl chloride.
  • a tough film is one which possesses at least the toughness of a film based on emulsion polyvinyl chloride.
  • the sections forming the base plate of the container are attached to the underside of the flanges of the top. In this arrangement, they enclose the cavity.
  • the two sections forming the base plate of the container overlap in such a manner that the overlapping edge of the overlapping section extends vertically below the folding line or folding notch in the top, so that a rectangular overlapping zone is formed.
  • the ceiling area is advantageously provided with a straight-lined, notch-like depression extending along the folding line, so that bending of the ceiling area along said line, which acts as the folding axis, is facilitated.
  • the container according to the invention is formed by fastening the hood-like top to the base plate, i.e., the top is placed with its flange upon the upper surface of the base plate and is sufficiently firmly and permanently joined with it.
  • the two parts may be combined in known manner, e. g., by stitching, sewing, or cementing.
  • the top consists of plastic material, in particular thermoplastic material
  • the base plate consists of cardboard with a heat-sealable layer thereon or of the same plastic film as the top, it is of advantage for the parts to be firmly combined by heat-sealing or welding.
  • Theflange of the overlapping area of the top is not fastened to the surface of the base plate. Therefore, this flange, which necessarily forms during the manufacture of the top from a planar film section by the thermoforming process, can be cut off.
  • the two sections forming the base plate are of such dimensions and are arranged in such a manner that opening and closing of the container is not impeded or prevented.
  • the two sections of the base plate are formed in such a manner that the section which is covered when the container is closed, ends in a tongue, and that the overlapping section of the base plate is provided with slots 7 for receiving this tongue.
  • the hinged part of the container is flipped around the folding axis in the ceiling of the molded top in such a manner that the outer surfaces of the resulting partial ceiling areas approach each other.
  • a slot-like opening is formed between the overlapping edges of the two sections which form the base plate, the width of the opening depending upon how far thetwo connected sections of the ceiling area approach.
  • the partial ceiling areas of the top which are at an angle to each other are pulled apart until a flat ceiling area is formed again.
  • the container is also closed by folding it around the folding line or axis.
  • the two pairs of partial side walls running parallel to each other at adistance corresponding to the width of the end walls must be approached until, as already described, the partial ceiling areas are in one plane again. This results in the above-described overlapping of the partial side walls.
  • the two sections of the base plate may be fastened in the area of the overlapping zone by known means, such as adhesive tape.
