Description

SPECIFICATION Box Made of Cardboard or Like Material This invention relates to boxes made of cardboard or like material.

According to this invention we provide a collapsible box made of cardboard or like material comprising a continuous wall and a bottom, the wall having one peripheral edge portion inturned to form a shoulder against which the said bottom can be supported to hold the wall in the open position.

One form of box made according to this invention is illustrated in the accompanying drawings wherein: Figure 1 is a perspective view of the box before erection, Figure 2 is a perspective view of the box erected and upturned, Figure 3 is a sectional detail view showing part of the shoulder and the wall bottom, Figure 4 is a perspective view of a modification, and Figure 5 is a perspective view of the box shown in Figure 4 erected and upturned.

Referring to the drawings and first to Figures 1 to 3; the box comprises two parts, a fold flat wall A made from a onepiece blank, preglued, and a separate bottom B. The wall A consists of two panels 2 and 3 with crease lines 4 between them so that the two panels 2 and 3 can be brought together for transport and/or storage. In Figure 1 the two panels 2 and 3 have been separated slightly to show the construction. In the case illustrated the box is intended for containing ice cream and is thus provided with lines of weakening 5 and a tap 6 projecting from one free end of the wall blank for ripping open the package. The lower edge portion of the wall A is provided with a circumferential half-cut or crease line 7 and crease lines 8 to facilitate folding.

In use, in order to erect the box the lower edge portion of the wall A is folded inwards along the crease line to lie against the wall so that the free edge of the wall forms a shoulder 9 of an inside panel 10. The bottom B is pressed into the wall A until it rests on the shoulder 9 holding the wall in the circular shape shown in Figure 2. The shoulder prevents the bottom from falling out.

The box has uses other than the one described and the wall can be made shallower so that the box can be used as a lid or tray. Also the bottom B may be of a different shape e.g. oval, the wall A of course taking up the shape of the bottom when in the erect condition. Furthermore the box may be polygonal e.g. hexagonal, ten-sided or multifaced and if desired the corners of the bottom may be truncated very slightly so as to seat in the bends of the wall when erected.

In the modification shown in Figures 4 and 5 the box is octagonal. The panel 10 is turned in and glued before collapsing for transport as shown in Figure 4. Pointed cuts 11 are made at the top of the wall which, when erected the tabs 1 2 formed by the cuts stick out and assist in securing a vacuum formed lid. Cut outs 14 are provided in the panel 10 at the fold line 7 thus avoiding a build up of material and possible cracking on the fold line.

In a further modification the wall, instead of having a glue flap, is provided with locking means at the free edges. The wall may be made up of more than two panels if desired. The bottom may be attached at one side instead of being a separate member.

Claims

1. Collapsible box made of cardboard or like material comprising a continuous foldable wall and a bottom, in which the lower edge portion of the wall is inturned to form a shoulder against which the said bottom can be supported to hold the wall in the open position.

2. Collapsible box according to claim 1 wherein the said wall is made from a one or more piece blank the ends of which are preglued together to form the continuous wall.

3. Collapsible box according to claim 1 or claim 2 wherein the inturned edge portion is glued to the blank before the continuous wall is formed.

4. Collapsible box according to any one of the preceding claims wherein the said bottom is round, oval or polygonal.

5. Collapsible box according to claim 1 wherein the ends of the wall blank are provided with locking means to hold the wall into its continuous shape.

According to this invention we provide a collapsible box made of cardboard or like material comprising a continuous wall and a bottom, the wall having one peripheral edge portion inturned to form a shoulder against which the said bottom can be supported to hold the wall in the open position. One form of box made according to this invention is illustrated in the accompanying drawings wherein: Figure 1 is a perspective view of the box before erection, Figure 2 is a perspective view of the box erected and upturned, Figure 3 is a sectional detail view showing part of the shoulder and the wall bottom, Figure 4 is a perspective view of a modification, and Figure 5 is a perspective view of the box shown in Figure 4 erected and upturned. Referring to the drawings and first to Figures 1 to 3; the box comprises two parts, a fold flat wall A made from a onepiece blank, preglued, and a separate bottom B. The wall A consists of two panels 2 and 3 with crease lines 4 between them so that the two panels 2 and 3 can be brought together for transport and/or storage. In Figure 1 the two panels 2 and 3 have been separated slightly to show the construction. In the case illustrated the box is intended for containing ice cream and is thus provided with lines of weakening 5 and a tap 6 projecting from one free end of the wall blank for ripping open the package. The lower edge portion of the wall A is provided with a circumferential half-cut or crease line 7 and crease lines 8 to facilitate folding. In use, in order to erect the box the lower edge portion of the wall A is folded inwards along the crease line to lie against the wall so that the free edge of the wall forms a shoulder 9 of an inside panel 10. The bottom B is pressed into the wall A until it rests on the shoulder 9 holding the wall in the circular shape shown in Figure 2. The shoulder prevents the bottom from falling out. The box has uses other than the one described and the wall can be made shallower so that the box can be used as a lid or tray. Also the bottom B may be of a different shape e.g. oval, the wall A of course taking up the shape of the bottom when in the erect condition. Furthermore the box may be polygonal e.g. hexagonal, ten-sided or multifaced and if desired the corners of the bottom may be truncated very slightly so as to seat in the bends of the wall when erected. In the modification shown in Figures 4 and 5 the box is octagonal. The panel 10 is turned in and glued before collapsing for transport as shown in Figure 4. Pointed cuts 11 are made at the top of the wall which, when erected the tabs 1 2 formed by the cuts stick out and assist in securing a vacuum formed lid. Cut outs 14 are provided in the panel 10 at the fold line 7 thus avoiding a build up of material and possible cracking on the fold line. In a further modification the wall, instead of having a glue flap, is provided with locking means at the free edges. The wall may be made up of more than two panels if desired. The bottom may be attached at one side instead of being a separate member. Claims

1. Collapsible box made of cardboard or like material comprising a continuous foldable wall and a bottom, in which the lower edge portion of the wall is inturned to form a shoulder against which the said bottom can be supported to hold the wall in the open position.

2. Collapsible box according to claim 1 wherein the said wall is made from a one or more piece blank the ends of which are preglued together to form the continuous wall.

3. Collapsible box according to claim 1 or claim 2 wherein the inturned edge portion is glued to the blank before the continuous wall is formed.

4. Collapsible box according to any one of the preceding claims wherein the said bottom is round, oval or polygonal.

5. Collapsible box according to claim 1 wherein the ends of the wall blank are provided with locking means to hold the wall into its continuous shape.

6. Collapsible box made of cardboard or like foldable material substantially as described with reference to Figures 1 to 3 or Figures 4 and 5 or as modified herein.
