Description

SPECIFICATION An improved container This invention relates to an outer protective case for a receptacle of the kind suitable for containing material having free flowing properties, and to a container consisting of a receptacle (typically a flexible receptacle) of the kind referred to when fitted within such an outer protective case.
According to one aspect of the invention there is provided an outer protective case for a receptacle for material having free flowing properties, the outer protective case being erected from a unitary blank of stiff yet foldable sheet material to have a rectangular crosssection, and being closed at one end by a pair of inner end closure flaps hingedly connected respectively to a first pair of opposite side walls of the outer protective case and an outer end closure flap hingedly connected to one or each of a second pair of opposite side walls, the or each outer end closure flap being foldable to overlie said pair of inner end closure flaps, the inner end closure flaps being adapted to be folded so that recessed portions, one of which is provided in each inner end closure flap, confront one another to define an aperture for receiving and locating the neck of a receptable which the outer protective case is designed to protect.
Suitably each inner end closure flap is folded to provide a further portion, extending in the direction from to the other of said second pair of opposite side walls, of polygonal cross-section.
Preferably each of said further portions is of tetragonal cross-section and consists of a first panel hingedly connected about a first axis to its respective side wall and extending inwardly substantially at right angles to the latter, a second panel hingedly connected to the first panel about a second axis, a third panel hingedly connected to the second panel about a third axis, and a fourth panel hingedly connected to the third panel about a fourth axis and disposed parallel to the respective side wall, each of the said axes being parallel to one another. Each of the included angles between the first and second panels and between the third and fourth panels is preferably greater than a right angle.
Conveniently each of the first, third and fourth panels extends completely between the said second pair of opposite side walls, and the second panel extends from one of said second pair of opposite side walls to an intermediate position between, e.g. mid-way between, the second pair of opposite side walls.
In this case the third panel, in the region between the said intermediate position and the other of said second pair of opposite side walls, extends inwardly away from the said third and fourth axes and has a recessed distal edge constituting the said recessed portion.
When the included angle between the first and second panels of each inner end closure flap is an obtuse angle, the second panel may be provided with a slot extending parallel to the said second pair of opposite side walls.
Flaps or tabs at the distal ends of two outer closure flaps are inserted into these slots to retain the flaps in a closed position.
The outer protective case may be provided with an internal floor which is inclined relative to one of the side walls, the internal floor being adapted to slope downwardly towards the said one end of the case and to provide a support for a receptable for fluent material positioned within the outer protective case in a dispensing position, when the outer protective case is positioned with its said one side wall resting upon a horizontal support surface.
Conveniently the internal floor is provided by a floor panel hingedly connected to, and integral with, the said one side wall, the floor panel being folded inwardly to lie against the end of the case remote from said one end and then being folded again to converge towards said one side wall and to provide the sloping receptacle supporting surface.
According to another aspect of the invention a container comprises an outer protective case according to said one aspect of the invention, and an inner receptacle for material having free flowing properties fitted within the outer protective case, the said inner receptacle having a neck positioned within the aperture defined between the said confronting recessed portions of the inner closure flaps of the outer protective case.
The invention will now be described, by way of example, with reference to the accompanying drawings, in which Figure 1 is an end view of an outer protective case according to the invention in which outer closure flaps are shown in an open position, Figure 2 is a section of the outer protective case shown in Fig. 1 taken on the line ll-ll but with the outer closure flaps shown in their closed position, Figure 3 is a section of the outer protective case shown in Fig. 1 taken on the line Ill-Ill but with the closure flaps shown in their closed position, Figure 4 is a schematic perspective view showing the way in which an inner closure flap of the outer protective case shown in Fig.
1 is folded, and Figure 5 is a plato of a unitary blank from which the outer protective case shown in Fig.
1 is formed.
Figs. 1 to 3 show an outer protective case, generally designated 1, for protecting a receptacle 2 (shown in chain lines in Figs. 2 and 3) for material having free flowing properties, such as a liquid or powder. The case 1, which is of rectangular cross-section and made of double faced twin corrugated board, has a first pair of opposite side walls 3 and 4 (see Fig. 3), a second pair of opposite side walls 5 and 6 (see Fig. 4), a bottom 7 and a top, generally designated 8, consisting of a first or inner pair of end closure flaps, generally designated 9 and 10, hingedly connected to the upper edges of side walls 3 and 4, respectively, and a second, or outer pair of end closure flaps, generally designated 11 and 12, hingedly connected to the upper edges of side walls 5 and 6, respectively.
Each inner end closure flap 9 (10) is folded about a plurality of parallel folds to provide a first panel 13(14) hinged connected to and extending inwardly perpendicular to, the side wall 3(4), a second panel 1 5(16) hinged to the first panel 13(14), a third panel 1 7(18) hinged to the second panel 1 5(1 6) and a fourth panel 19(20) hinged to the third panel 17(18) and positioned against, substantially parallel to, the side wall 3(4). Each of the panels 13, 17 and 19(14, 18 and 20) extends from side wall 5 to side wall 6, whereas the second panel 15(16) extends from side wall 6 to a plane 21 (see dotted line in Fig. 2) positioned midway between, and substantially parallel to, the side walls 5 and 6.Each folded inner end closure flap 9(10) thus has a portion, extending from the side wall 6 to the plane 21, for tetragonal crosssection. The portion of each end closure flap 9(10) extending from the side wall 5 to the plane 21 has no panel connected between the first and third panels 1 3(14) and 1 7(1 8), respectively. However the portion of the third panel 17(18) positioned between side wall 5 and the plane 21 extends from its hinged connection with the fourth panel 19(20) to a position in which its distal edge 22(23) is positionedadjacentaplane 24 (see dotted line in Fig. 3) positioned midway between, and substantially parallel to, the side walls 3 and 4.A semicircular recess 25, 26 is formed in each distal edge 22, 23, respectively; the semi-circular recesses 25, 26 together defining a circular recess for receiving a screw-threaded circular neck 27 of the receptacle 2. Although it is possible for the hinging angle formed between the third and fourth panels 17 and 1 9 (18 and 20) to be equai to, or less than, a right angle, it will be appreciated that it is preferred that this angle is an obtuse angle since this ensures that the third panels are angled downwardly (as viewed in Fig. 3) towards each other and are thus able to resist any tendencycfor the receptacle 2 to move upwardly within the outer case 1.
A slot 28(29) is provided in each panel 1 5(1 6) for receiving folded over portions of the end closure flaps 11 and 1 2. To enable interengagement of the flaps 11 and 1 2 in the slots 28 and 29 it is preferable that the hinging angle formed between each of the first and second panels 1 3 and 1 5 (14 and 1 6) is an obtuse angle.
A pair of finger holes 30(31) is provided in the upper part of each side wall 3(4). Each finger hole is formed by making a cut of substantially U-shape in the particular side wall 3, 4 and folding the cut portion inwardly to provide a tab 30a 31 a.
Each pair of tabs 30a, 31 a is then received in an opening 32(33) formed in each of the third and fourth panels 17 and 19 (18 and 20) along the folding axis between the third and fourth panels.
The openings 32 and 33 are formed by cutting the inner end closure flaps 9 and 10, respectively, to provide tabs 32a and 33a, respectively. These tabs 32a, 33a are bent back to ensure that a user's fingers pass through the openings 32, 33 instead of being located beneath the panels 17, 19.
The location of each tab 30a, 31 a in each opening 32, 33, respectively, ensures that the inner closure flaps 9 and 10 remain in their folded conditions.
Although the container consisting of the receptacle 2 and outer case 1 is intended to be transported in the upright position shown in Figs. 2 and 3, it should be realised that when in a final dispensing position, e.g. on a shelf of a shop, the side wail 5 will constitute the bottom of the container and the side wall 6 will constitute the top of the container. The side wall 5 has a panel 34 integrally hinged to its lower edge which is folded inwardly perpendicular to the side wall 5 to be adjacent and parallel to the bottom 7. A further panel 35 is hingedly connected to the panel 34 and is folded upwardly so that its distal edge is located adjacent the side wall 5.The panel 35 is retained in the position shown in Fig. 2 by the interengagement of tabs 36 and 37 (see Fig. 5), provided adjacent the distal edge of the panel 35, in recesses 38 and 39, respectively, formed in panes 40 and 41 which are hingedly connected to the bottom 7 and which are folded to lie parallel to, and in contact with, the side walls 3 and 4, respec tiveiy. When the container is in its dispensing position, the panel 35 provides a sloping floor to facilitate the dispensing of fluent material from the receptacle 2. A dispensing opening 42 may be provided in the side wall 5 and outer end closure flap 11 of the case 1.
Fig. 5 shows a one-piece blank 50 from which the outer case 1 is erected. In Fig. 5 the dashed lines represent fold lines in a direction upwardly out of the plane of Fig. 5, the dotted lines represent fold lines in a direction downwardly into the plane Fig. 5, the chain lines represent perforated cut lines, and the full lines represent full cut lines.
Since it will be obvious to a person skilled in the art how the blank 50 is folded to form the erected, outer case 1, this will not be described in detail. However it should be realised that the outer case 1 is retained in its erected position by fixing, e.g. stapling, glueing or taping, flap 51, which is hingedly connected to side wall 5, to the inside of the side wall 3.
Although the outer case 1 has a pair of outer end closures 11 and 12, it would be possible in an alternative constuction to provide a single outer end closure extending from one to the other of side walls 5 and 6.
It should be realised that the outer case 1 need not necessarily be made of double faced twin corrugated board. Instead the outer case 1 may be made out of double faced singular corrugated board or any other suitable stiff yet foldable material.
