Description




TECHNICAL FIELD AND BACKGROUND OF THE INVENTION




The present invention relates to containers, and particularly, but nor exclusively, to containers for use in delivering goods to retail premises.




Goods being dispatched to retail premises are conventionally packed into reusable containers, boxes or crates which can be stacked on each other during transportation and storage. In order to facilitate return transportation when empty, it is conventional to design the containers to be nestable one within the other, so that a large number of empty containers can be stored or transported in a compact manner. Nesting is conventionally achieved by providing side walls which slant or slope up to the upper mouth of the container, so that the base of another container can be received partially into an empty container below. However, the slanting nature of the walls can give rise to packing problems, particularly in relation to goods which are packed in parallelepipedal packaging. The slanting of the walls means that lateral movement of the goods may not be adequately prevented, giving rise to the risk of damage, particularly during transit.




SUMMARY OF THE INVENTION




The present invention provides a container comprising walls upstanding from a base to define a space within which items may be placed, the walls being sloped to allow the container to nest within a like container, and the container further comprising at least one filler member locatable within the space at a position fixed relative to one of the walls, the filler member, when so located, defining a substantially vertical boundary to the said space.




The filler member may be releasably fixed as aforesaid. The filler member is preferably movable away from the said fixed position, to allow nesting. The filler member may be attached to the container, and movable to or away from the fixed position. The filler member is preferably hingedly attached to the container.




The filler member may be attached to hinge down to the base when moving away from the fixed position. The filler member is preferably hingedly attached to the container along a lower edge of the filler member.




Alternatively, the filler member may be attached to hinge out of the container space. The filler member may be attached to hinge out to a position alongside the outer surface of the container. The filler member may be hingedly attached to the container along an upper edge of the filler member.




Preferably a plurality of filler members are provided. Each wall of the container preferably has an associated filler member.




The container preferably further comprises lid means attachable to the container to close the container space from above. The lid means may be adjustably attachable to allow the sides of the container space to be altered. The lid means may be attachable by means of a line of slots, and a tab movable into a selectable one of the slots to be retained thereby. The slot means may comprise a line of retention slots connected by a connection slot along which the tab is movable between retention slots. There may be a plurality of attachment means as aforesaid. Preferably, attachment means as aforesaid are provided to attach the lid means in the region of each corner of the container. The attachment means may be provided, in part by the filler member.

DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE





FIG. 1

shows a container


10


comprising walls


12


which are upstanding from a base


14


to define a space


16


within which items (not shown) may be placed, such as for transportation or storage. The walls


12


are sloped (

FIG. 2

) to allow the container


10


to nest with a like container. The container


10


further comprises filler members


18


locatable within the space


16


at positions fixed relative to the walls


12


. When so located, the fillers


18


define, in use, a substantially vertical boundary to the said space.




The container


10


is also provided with two leaves


20


of a lid, hinged at


22


along the upper edge of two opposed walls


12


, so that the leaves


20


can hang down outside the container


10


(as shown in

FIG. 1

) or can swing over the top of the container, to dose the space


16


.




The walls


12


slope up from the base


14


, to lean outwardly, as can be seen in FIG.


2


. Consequently, the width W of the container increases from the width of the base


14


, up to the width of the upper mouth of the container


10


. It can therefore readily be understood that the walls


12


cannot themselves retain items against lateral movement to the same degree near the top of the container, as they can near the base


14


, because of this increased width.





FIG. 2

shows two fillers


18


provided in accordance with the invention, adjacent opposed walls


12


. In the simple arrangement illustrated, each filler extends up the inside face of the corresponding wall


12


, and becomes progressively thicker. Appropriate choice of angles and dimensions for the filler


18


allows the filler to be positioned as shown in

FIG. 2

, with an outer surface


24


closely adjacent the inner face of the corresponding wall


12


, and an inner surface


26


facing into the space


16


and being substantially vertical. Thus, with two opposed fillers


18


located as illustrated in

FIG. 2

, the space


16


is converted into a vertical sided space, within which articles can be held against lateral movement to the same extent at any height above the base


14


.




It will be readily apparent that in order to achieve this, the filler


18


could provide a continuous vertical surface, or a broken surface (such as ribs, a mesh or the like), either alternative serving to define a substantially vertical boundary to the space


16


.




The fillers


18


are attached by hinges


30


to the base


14


along their lower edge, so that when in the positions shown in

FIG. 2

, the fillers


18


(and their surfaces


26


) will be in a fixed position relative to the corresponding wall


12


. However, the hinges


30


allow the fillers


18


to fold down over the base


14


, within the container


10


, to the position shown in FIG.


3


. This exposes again the sloping inner surfaces of the walls


12


, so that the container


10


can again be nested with a like container introduced from above. Once the containers are fully nested, the folded down fillers


18


will be contained within the space between the bases of the nested containers.





FIGS. 2 and 3

show arrows


32


which illustrate how the upper edges of the fillers


18


move between the folded down position (

FIG. 3

) up to the position for use (FIGS.


1


and


2


).





FIG. 4

illustrates schematically another alternative arrangement for the fillers


18


. In this alternative, each filler


18


is attached to the upper edge of a wall


12


, along the upper edge of the filler


18


, by hinges


34


. The hinges


34


allow the fillers


18


to be removed from the space


16


by hinging to raise the lower edges of the fillers


18


, swinging them out over the wall


12


, until the fillers


18


hang down outside the container


10


(in a position similar to the hanging leaves


20


illustrated in FIG.


1


). This movement is illustrated in

FIG. 4

by arrows


36


. Again, the effect is to expose the sloping walls


12


, to allow nesting of like containers.




The alternative illustrated in

FIG. 4

may be particularly advantageous in a situation where the container


10


is not required to have a lid, so that there are no lid leaves


20


.





FIGS. 5 and 6

illustrate arrangements for providing the container with a packing lid


38


which can be moved down onto goods within the container


10


, to help hold those goods during transit, but can readily be removed when access to the container


10


is required. The lid


38


consists of a generally planar member which is provided at or near each corner with a small tab


40


. Each of these tabs


40


can cooperate with slot arrangements


42


in the vertical faces of the fillers


18


. Each slot arrangement


42


consists of a central connection slot


44


, which runs generally vertically and from which extend sideways a large number of generally horizontal retention slots


46


. This arrangement is illustrated schematically in

FIG. 6

, which shows in cross-section the tab


40


, which is of an appropriate size to be received in any selected retention slot


46


, so that vertical movement of the lid


38


in either direction is prevented. However, the tab


40


can slide from the retention slot


46


into the connection slot


44


, whereupon vertical movement of the lid


38


then becomes possible again, allowing the lid


38


to be raised or lowered to a new position, and then slid laterally to engage each tab


40


with a corresponding retention slot


46


at the new height. Consequently, by simple sideways movement, the lid


38


can be freed for vertical movement, allowing the lid


38


to be pressed down onto goods within the container


10


, to hold those goods, the lid


38


thereafter being locked in position by engagement of the tabs


40


and slots


46


.




It will be apparent that many variations and modifications can be made to the apparatus described above, without departing from the scope of the invention. In particular, dimensions and relative dimensions can be widely varied. The form of one attachment between the lid


38


and the fillers


18


can be altered, or the lid


38


may be dispensed with. The fillers


18


are preferably permanently attached to the container


10


, but could alternatively be removable when not in use. Fillers may be provided for all walls of the container, or for only some of them. Components of the container can be manufactured from many different materials, but injection moulding from a plastics material is envisaged.




Various references have been made to “vertical”, “up”, “down” and the like. These references are made because containers for many uses, including retail uses, are usually required to have an open top, a generally horizontal base, and upstanding walls. Stacks will generally be vertical for stability. Consequently, inside boundaries which are perpendicular to the base, as provided by the fillers, will be vertical. However, it will be readily understood that the same principles of the invention could be applied with other orientations, if required for a particular purpose.




Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon,
