Description
Improvements in or relating to containers
This invention relates to containers and more particular, but not exclusively, is concerned with cartons suitable for carrying take-away meals.
According to one aspect of the present invention there is provided a container formed from sheet material and comprising: (i) a rectangular, for example square bottom
portion; (ii) first and second side portions attached to the
bottom portion, (iii) first and second end portions attached to the
bottom portion; and (iv) first, second, third and fourth pairs of gusset
portions, the gusset portions of each pair being
attached together and a pair of said gusset
portions being located between and attached to
each respective pair of adjacent side and end
portions, wherein the gusset portions of each
pair are folded such that a surface of one
gusset portion of the pair is superposed on a
surface of the side or end portion adjacent
thereto and is held in such superposition by
adhesive provided on said sheet material.
In a particularly preferred embodiment, the adhesive is locally provided between said surface of said one portion of each pair of gusset portions and the respective surface of the side or end portion adjacent thereto. Thus a spot of adhesive is provided at four separate locations so as to adhere each pair of gusset portions to the side or end portion adjacent thereto. The adhesive may be a hot melt adhesive or, for example, a pressure sensitive adhesive such as a polyvinyl acetate adhesive for example that known under the trade designation Copydex
Alternatively, the sheet material may be a heat sealable material in which case the superposed surfaces are held in superposition by heating appropriate localised areas of the material by means of, for example, a hot air gun.
In a particularly preferred embodiment, the container is wedge-shaped in that the side and end portions taper outwardly from the bottom portion.
Preferably, the container includes first and second top portions attached to the first and second end portions respectively and, in this case, first and second closure portions may be provided attached to the first and second side portions and adapted to overly said top portions. In the latter case, the first and second closure portions preferably include interlockable parts so as to retain the closure port ions together.
The sheet material may be any type of carton board coated with waterproofing material (such as polyethylene) on at least that surface of the sheet material which is to define the internal surface of the container in the case where the container is to be used for carrying non-solid materials such as ready cooked take-away food. However, the container can be used to carry foods such as frozen foods or other solids in which case it may not be essential for the sheet material to be water proof.
According to another aspect of the present invention, there is provided a carton blank for forming into a container as described above, the carton blank being formed of sheet material and comprising: (i) a rectangular, for example square, bottom
defining portion having opposite sides and
opposite ends, (ii) first and second side-defining portions attached
to the sides of the bottom-defining portion; (iii) first and second end-defining portions attached
to the ends of the bottom-defining portion; and (iv) first, second, third and fourth pairs of gusset
defining portions wherein each pair of said
gusset-defining portions is located between and
attached to each respective pair of adjacent
side- and end-defining portions and wherein the
relative dimensions of the gusset- and side
defining portions are such that the length of
the side-defining portion is greater than twice
the length of the maximum width of the gusset
defining portion as measured in a direction
parallel to the sides of the bottom-defining
portion.
For a better understanding of the invention and to show how the same may be carried out, reference will now be made, by way of example, to the accompanying drawings in which:
Figure 1 is a plan view of a carton blank in accordance with the present invention,
Figure 2 is a perspective view of a partially completed container in accordance with the invention formed by appropriately folding the carton blank of
Figure 1,
Figure 3 is a view similar to Figure 2 showing the container at a further stage in its completion,
Figure 4 is a view similar to Figure 2 showing the carton in its complete form but with the closure therefor still open, and
Figure 5 is a perspective view of the container of
Figure 2 with the closure portion in its closed and interlocked configuration.
Referring to the Figures, and particularly to
Figure 1, the carton blank comprises a rectangular bottom-defining portion 1 having opposite sides 2 and 3 and opposite ends 4 and 5. Attached to the opposite sides 2 and 3 are first and second side-defining portions 6 and 7, respectively of regular trapezoidal shape such that their width dimension increases with an increase in distance from portion 1. Similarly, attached to opposite ends 4 and 5 are trapezoidal shaped first and second end-defining portions 8 and 9, respectively. A first pair of gusset-defining portions 10 and 11 is provided between the first side-defining portion 6 and the first end-defining portion 8 adjacent thereto. The gusset-defining portions 10 and 11 are attached together, with portion 10 being attached to the first side-defining portion 6 and portion 11 being attached to the first end-defining portion 8.A second pair of gusset-defining portions 10 and 11 is similarly located between and attached to the first end-defining portion 8 and the second side-defining portion 7. A third pair of gusset-defining portions 10 and 11 is similarly located between and attached to the second side-defining portion 7 and the second end-defining portion 9. A fourth pair of gusset-defining portions 10 and 11 is similarly located between and attached to the second end-defining portion 9 and the first sidedefining portion 6.
The relative dimensions of the gusset-defining portions 10 and 11 and of the side-defining portions 6 and 7 are such that the maximum width of each gussetdefining portion when measured in a direction parallel to one of the sides 2 and 3 of the bottom-defining portion 1 (i.e. width W as shown in chain-dotted lines in Figure 1) is less than half the maximum length of side-defining portion 6 or 7.
First and second top-defining portions 12 and 13 are attached to the first and second end-defining portions 8 and 9, respectively. First and second closure-defining portions 14 and 15 are attached to first and second side-defining portions 6 and 7, respectively. The first closure-defining portion 14 includes a slot 16 and the second closure-defining portion 15 includes a tab 17 which is capable of interlocking with the slot 16.
The carton blank is provided with a plurality of score lines between adjacent portions and these are shown in dotted lines in Figure 1. These score lines serve as fold lines whereby the carton blank can be suitably folded to form the container shown in Figures 2 to 5.
The carton blank is formed of carton card coated on the surface intended to form the inner surface of the container with polyethylene.
In use, spots of adhesive are applied to appropriate areas of the blank which is then suitably folded, preferably using an appropriate carton-forming machine, to form the carton with the innermost gussetdefining portions (portions 10) adhered to the surfaces of the side defining portions adjacent thereto by means of the adhesive. More particularly, the blank is folded by folding the first and second side-defining portions 6 and 7 and the first and second end-defining portions 8 and 9 so that they are generally upstanding with respect to the bottom-defining portion 1. In order to facilitate this, each pair of gusset portions 10 and 11 is folded so that the portions 10 and 11 of each pair are brought towards one another with the fold line between the portions 10 and 11 being positioned further away from the centre of the container than the side-defining and end-defining portions so that each pair of gusset portions is in the form of a wing located at, and externally of, a corner of the container defined by adjacent side- and end-defining portions.
Each wing constituted by a pair of gusset-defining portions 10 and 11 is folded in the direction shown by arrows 18 in Fig. 2 so that both portions 10 and 11 of each pair are superposed on the side-defining portions 6 and 7 and a wing is located at each end of the sidedefining portions. Each wing constituted by the superposed gusset-defining portions 10 and 11 is thereby adhered to its respective side-defining portion 6 or 7 by means of the spot of adhesive (not shown) located between the surface of the innermost gussetdefining portion (portion 10) of each wing and the surface of the side-defining portion adjacent thereto.
The top-defining portions 12 and 13 are folded downwardly in the directions shown by the arrows 19 (Fig. 3) and the first closure-defining portion 14 is folded in the direction shown by arrows 20 in Figure 4 so that it overlies the top-defining portions 12 and 13. The second closure-defining portion 15 is folded over the first closure-defining portion 14 and its tab 17 is threaded into slot 16 in the first closuredefining portion 14 to securely close the resultant container as shown in Figure 5.
As a consequence of the length of the sidedefining portion 6 or 7 being more than twice the length of the width W of gusset portion 10 or 11, the wings at opposite ends of the side-defining portions 6 and 7 do not overlap one another when they are superposed on their respective side-defining portions 6 and 7.
As will be apparent, the container is generally wedge-shaped and comprises a rectangular bottom portion (1), first (6) and second (7) side portions attached to the bottom portion, first (8) and second (9) end portions attached to the bottom portion, and four pairs of gusset portions (10 and 11) located between and attached to adjacent side and end portions. Each pair of gusset portions has been folded so that a surface of gusset portion 10 is superposed on, and locally adhered to, the adjacent side portion. The top of the container is closed by top portions (12 and 13) which are held in place by interlocking first and second closure portions (14 and 15). The container is particularly suitable for use as a container for "takeaway" foods.
