Description:
Packaging Blank and Container

Technical Field:

A frozen confection packaging blank (1) comprising four or greater than four flaps (14, 17) and an insert panel (10) optionally comprising one or more apertures (12) and separator panels (1 1). The frozen confection container assembled from the frozen confection packaging blank (1) and its use as primary packaging for frozen confection products.

Background:

Typically, frozen confections that are to be sold in multipack containers at supermarkets in order to be transported by the consumer to their home and stored for consumption over a period of time, are wrapped in both primary and secondary packaging. These products are usually referred to as in-home products. The primary packaging is typically a flexible wrapper, such as the wrapper of the SOLERO™ product, that wraps each frozen confection product item individually. The primary packaging provides a waterproof barrier both to retain any liquid that melts from the frozen confection and to prevent any exposure of the frozen confection to ambient conditions that may contain moisture causing undesired frosting on the surface of the frozen confection. Additionally, the primary packaging prevents any secondary packaging from absorbing any liquid originating from the frozen confection, thereby saturating the secondary packaging material and reducing the structural integrity of the secondary packaging material. Furthermore, the primary packaging, when used in a multipack container prevents the frozen confections contained in that container from adhering to each other, consequently preventing damage of the frozen confections.

In order to sell the individually wrapped frozen confection products in a multipack format, the individually wrapped frozen confections are held in secondary packaging, e.g.: a frozen confection container box, such as the SOLERO™ secondary packaging box that comprises five individually wrapped frozen confection products. In addition to providing a structure to contain the multiple frozen confection products, the secondary packaging structure provides protection from damage of the frozen confection products due to external forces applied (such as forces experienced when a box is dropped). Current consumer demand is driving a change in packaging trends to develop packaging that is recyclable and results in less waste when discarded. In order to meet these demands alternative primary packaging has been developed. For example, frozen confection packaging provided by Dr Feelgood (New Zealand) meets the demands of reducing waste by individually packing frozen confection products in a box, i.e. combining some of the benefits of secondary packaging, such as structural protection and recyclability, with the benefits of primary packaging, e.g.: ensuring frozen confections do not adhere to each other. However, this packaging is less suitable as packaging for in-home products as, during transportation of the frozen confection product to the customer’s home, the frozen confection is likely to melt and produce a liquid that will leak from the packaging. As can be seen from the packaging, two webbed corners (corner flaps) are present; however, the structure of the base of the packaging is a fold and therefore not water-proof. This is particularly problematic for frozen confection products with a high-water content and may also be as problematic for coated frozen confection products where the coating is cracked or damaged. When damaged coating does not function as a barrier to contain, for example, a melted ice cream, the melted frozen confection material is able to leak from the frozen confection product and packaging in the same way as the high-water content frozen confection.

The MAGNUM™ Bomboniera product is an example of multipack box for an in-home product wherein the traditional flexible wrapper primary packaging has been avoided; however, in addition to the traditional secondary packaging of a container box, an tray insert must be provided in order to prevent the frozen confections from knocking against each other and damaging each other during transport. Additionally, if the coating of the frozen confection is broken, leakage of melted ice cream from the unsealed secondary packaging during transportation could be problematic.

There is a need to provide an in-home product that allows the removal of one of the two packaging items currently necessary for multipack in-home products, thereby reducing packaging waste and potentially increasing the recyclability of product packaging. In particular there is a need for products with a reduced amount of packaging, i.e.: one item of primary packaging, that provides the benefits of both current primary and secondary packaging and enables the frozen confection to be transported from a site of purchase to a domestic (consumer’s) freezer without the observed problems of leakage of frozen confection from the packaging. It would be a further advantage if it is possible to transport the package containing the frozen confections at any angle; i.e. : no or significantly reduced leakage would occur from the package regardless of orientation of the package within, for example, a shopping basket or bag. In addition to these advantages, the structure of the frozen confection container provides additional robustness when tertiary packaging is applied to bind several frozen confection containers.

In an aspect of the invention the frozen confection packaging blank (1) has four flaps attached to each end of the first and second side panels (5,9), each flap is selected from the group consisting of side panel flaps (14a, 14b, 14c, 14d) and corner flaps (17a, 17b, 17c, 17d); i.e.: the flap present at a particular side panel (5 or 9) is selected from a side panel flap corresponding to side panel flap 14a, 14b, 14c or 14d, or corresponding to corner flap 17a, 17b, 17c or 17d.

In an embodiment of the invention the frozen confection packaging blank (1) comprises four flaps that are side panel flaps (14a, 14b, 14c, 14d).

In an embodiment of the invention the frozen confection packaging blank (1) comprises four flaps that are corner flaps (17a, 17b, 17c, 17d). Where the flap is a corner flap, the flap must be in contact with either the first or second side panel (5,9) and the front lid flap (3) or front base flap (4). A corner flap may also be known as a‘webbed’ corner flap to the person skilled in the art.

In an embodiment of the invention, the frozen confection packaging blank (1) comprises two corner flaps (17a, 17b, 17c or 17d) and two side panel flaps (14a, 14b, 14c or 14d). In an embodiment of the invention, the frozen confection packaging blank (1) comprises from one to three flaps selected from the group consisting of corner flaps (17a, 17b, 17c or 17d) and side panel flaps (14a, 14b, 14c or 14d).

In an embodiment of the invention, the frozen confection packaging blank (1) consists of two corner flaps (17a, 17b, 17c or 17d) and two side panel flaps (14a, 14b, 14c or 14d).

The two edges of the side panel flap (14a, 14b, 14c or 14d) oriented in the same direction as the longest length of the side panel (5,9) may be the same length or different lengths. For example, the side panel flaps of figure 3 where the frozen confection packaging blank (1) comprises two corner flaps (17a, 17d) and two side panel flaps (14b, 14c). The two edges of the two side panel flaps (14b, 14c) are different lengths in comparison to each other, the length of the side panel flaps (in the position corresponding to the positions of 17c and 17d of figure 2) that are attached to the front base flap (4) are 100% of the length of the front base flap (4), whereas the other edges are significantly smaller in length; i.e.: 40 % of the length of the front base flap (4).

In a further embodiment of the invention 30 % to 100% of the side panel flap (14a, 14b, 14c, 14d) has a width (L) of 100 % of the width of the side panel (5, 9) [width (N)] it is attached to, and from 0% to 70% of the side panel flap (14a, 14b, 14c, 14d)) has a width (L) of less than 100 % of the width of the side panel (5, 9) [width (N)] it is attached to.

In a further embodiment of the invention 40 % to 100% of the side panel flap (14a, 14b, 14c, 14d) has a width (L) of 100 % of the width of the side panel (5, 9) [width (N)] it is attached to, and from 0% to 60% of the side panel flap (14a, 14b, 14c, 14d) has a width (L) of less than 100 % of the width of the side panel flap (5, 9) [width (N)] it is attached to.

Side panel flap width (L) means the length of the side panel flap (14a, 14b, 14c, 14d) in a coaxial direction with the width of the side panel (5, 9) [width (N)] and fold line M. Typically, the width of the side panel (5, 9) [width (N)] is coaxial with the longitudinal direction of the frozen confection packaging blank, wherein the longitudinal direction of the frozen confection packaging blank is measured from the edge of the front panel (2) to the separator flap (13) positioned furthest from the front panel (2). Edge of the front panel (2) is intended to mean the edge of the front panel (2) that is not attached to any other feature of the blank and is the furthest distance from fold line F.

In a further embodiment of the invention the corner edges (18a, 18b) of the corner flaps (17a, 17b, 17c, 17d) are from 30 to 100 % of the length of one of the front lid flap (3), front base flap (4), back lid flap (7), back base flap (8), or first or second the side panel (5, 9).

In a further embodiment of the invention the corner edges (18a, 18b) of the corner flaps (17a, 17b, 17c, 17d) are from 40 to 100 % of the length of one of the front lid flap (3), front base flap (4), back lid flap (7), back base flap (8), or first or second the side panel (5, 9).

Fold means a weakened area of packaging blank material weekend by creasing, scoring or partial cutting on the face of the blank that is to form the outside of the packaging, i.e.: the face that will not be in contact with the frozen confection products. The partial cut should not penetrate the moisture barrier material of the inside of the container. The fold is not a full cut. The corner flaps (17a, 17b, 17c, 17d) comprise a fold (K) positioned at a diagonal from the corner of the flap at the junction of folds B and D; D and E; E and C; and B and C; towards the opposite corner of the flap where the corner edges (18a and 18b) meet. The fold (K) of the corner flap is from 10 to 80% in length a partial cutting on the face of the blank that is to form the outside of the packaging, the remainder of the fold is a crease. The fold (K) of the corner flap is from 20 to 70% in length a partial cutting on the face of the blank that is to form the outside of the packaging, the remainder of the fold is a crease. Preferably the fold (K) of the corner is from 30 to 60% in length a partial cutting on the face of the blank that is to form the outside of the packaging, the remainder of the fold is a crease.

In a further embodiment of the invention the frozen confection packaging blank comprises an insert panel (10) comprising one or more apertures (12) and separator panels (1 1). The separator panels (11) comprise a separator flap (13) distal to fold (J), wherein fold (J) attaches the separator panel (1 1) to the insert panel (10).

The width of the insert panel (10), i.e. the length of the panel from fold A to the distal edge of feature (13), distal from fold A, may preferably be equivalent to the width of the back panel (6) from fold B to fold E. Alternatively, the width of the insert panel (10) may be from 5 % to 50 % of the width of the back panel (6) from fold B to fold E; from 10 % to 20 % of the width of the back panel (6) from fold B to fold E.

Back base flap (8) may comprise holes (19a, 19b) to allow adhesive from front base flap (4) to pass through the back base flap (8) and secure the side panel flaps (14a, 14d) to the back and front base flaps (4, 8).

Use of the terms‘front’ and back’ are nominal terms to distinguish the faces of the frozen confection container and do not require these panels to be the panel decorated on the outside with the front and back of box graphics, respectively. The front lid flap and back lid flap are interchangeable; i.e.: It possible that the front lid flap (3) is attached to the back panel (6) and the back lid flap (7) is attached to the front panel (2).

Any locking mechanism that enables the container to be closed once the container has been opened may be used, preferably the locking mechanism is a tuck-in tab lock.

A further aspect of the present invention is a frozen confection container (20) assembled from the frozen confection packaging blank (1).

In one embodiment the frozen confection container (20) comprises one more of the side panel or corner flaps adhered to the adjacent front or back lid flap, or front or back base flap.

In another embodiment the frozen confection container (20) comprises one more of the side panel or corner flaps are not adhered to the adjacent front or back lid flap, or front or back base flap.

A frozen confection container (20) wherein the side panel or corner flaps are secured with an adhesive. Preferably the adhesive is a hot-melt adhesive (tecbond) applied via a Hot Melt glue gun.

In a further embodiment of the invention the frozen confection container (20) assembled from the frozen confection packaging blank comprises an insert panel comprising from two to six apertures (12) and separator panels (11), from three to five apertures (12) and separator panels (11), preferably four apertures (12) and separator panels (1 1). The frozen confection container comprising at least one insert panel (10) and at least one separator panel (11) and apertures (12), forms a frozen confection container (20) with cavities (21) corresponding to the number of separator panels (1 1) present. For example, a frozen confection packaging blank (1) with n number of separator panels (11) results in a frozen confection container (20) assembled comprising n+1 cavities (21). The frozen confection container (20) comprises from two to seven cavities (21), from three to six cavities (21), preferably from four to five cavities (21).

Once assembled, the cavities (21) of the frozen confection container (20) are typically as small as possible in width in order to protect the frozen confection products from damage experienced by the products when the container is moved. Additionally, the smallest possible amount of material used to make the container, i.e. : to form the smallest possible cavity size, results in the smallest possible amount of packaging material used to prepare the container (20), providing an additional feature that reduces the amount of waste that will eventually be discarded by the consumer. The width of the cavities are from 102 % to 120% of the width of the frozen confection product held therein; from 105 % to 115% of the width of the frozen confection product held therein; preferably from 108 % to 1 12% of the width of the frozen confection product held therein. Width means the length of the cavity orthogonal to both the longest length of the cavity and the shortest length of the cavity; i.e.: where the cavity is the shape of a rectangular cuboid, the width is the second largest dimension.

Once assembled, the cavities (21) of the frozen confection container (20) are typically as small as possible in height order to protect the frozen confection products from damage experienced by the products when the container (20) is moved. The height of the cavities (21) are from 102 % to 140% of the longest length of the frozen confection product held therein; from 103 % to 138% of the longest length of the frozen confection product held therein; preferably from 104 % to 135% of the longest length of the frozen confection product held therein. The longest length of the frozen confection product does not include the length of the stick where the frozen confection product comprises a stick, i.e. the frozen confection product is a frozen confection stick product. Height is measured from the base of the frozen confection container; i.e. the end of the box in contact with the frozen confection; e.g.: the tip of the frozen confection. In a further embodiment the insert panel (10) is adhered to the back panel (6) of the frozen confection container. Preferably, the insert panel (10) is adhered to the back panel (6) of the frozen confection container by providing adhesive to the distal separator flaps (13) and folding the insert panel (10) towards the back panel (6) at fold A.

A frozen confection container for use as primary packaging for frozen confections. As demonstrated by the experimental examples, the frozen confection container provides a reduced leakage or leak-proof frozen confection container suitable for use as a multipack frozen confection container that can be used for in-home products; i.e. suitable for use as a carrier for transport of the frozen confection products for greater than ten minutes between a point of purchase and a freezer, e.g.: a domestic, wherein at least one of frozen confection products held within the frozen confection container remains held within the container to be stored in the freezer for consumption at least ten minutes after storage.

A frozen confection container for use as primary packaging for frozen confections, wherein the frozen confection container is the sole packaging for the frozen confection products.

The frozen confection packaging blank (1) and consequent frozen confection container (20) may be prepared from a cardboard material coated on one or both faces with a moisture barrier material. The cardboard comprises two surfaces: an inner and an outer surface. The inner surface is the surface that will be on the inside of the container when the container has been assembled; i.e. the surface that will be in contact with the frozen confection products once the container has been packed with such products. The outer surface of the cardboard is the surface that a consumer will see before opening the container, this surface typically comprises printing and decoration. Preferably the carboard material is coated on the inside surface of the container, i.e.: the surface of the container that is in contact with the frozen confection products once the container is packed. Preferably the coating material is material is plastic polymer or bio-plastic polymer based material; e.g.: a polyethylene material. The container may also be coated in a printing material in order to provide information, for example, regarding the product contained therein, and to decorate the container. In an embodiment, the packaging material of the frozen confection container is cardboard coated with polyethylene; wherein the cardboard is coated on one side and the uncoated side is the inside of the container; i.e. the side or face of the container that is in contact with the frozen confection products once packed into the container.

Packaging of the frozen confection products into the frozen confection container (20) may be automated or manual; when automated, a pick and place or vortex robot is used. Preferably, the stick end of frozen confection stick products will be positioned at the lid flap (3, 7) end of the container. It is therefore a further aspect of the invention that the frozen confection container comprises frozen confection products. Typically, the number of frozen confection products present in the frozen confection container equals the number of cavities present. It is a further aspect of the invention that the frozen confection container comprises frozen confections separated by compartment walls; i.e. the walls of the cavities (21) prepared from the insert panel (10), separator panels (11) and separator flaps (13).

The method of preparing the frozen confection container (20) and frozen confection container (20) comprising frozen confection products comprising the steps of:

a. Providing a frozen confection packaging blank (1);

b. Applying adhesive to the inner surface of one or more distal separator flaps (13); c. Folding the blank at Fold line A to secure insert panel (10) to back panel (6);

d. Applying an adhesive to the outer surface of the insert panel (10) adjacent to fold line A and at one or more points distal to fold line A;

e. Folding the product of step d. at Fold line B to secure insert panel (10) to front panel

(2); f. Auto-pop up of frozen confection packaging blank (1) to form a 3D shape;

g. Folding the two side panel flaps (14a, 14d) or corner flaps (17c, 17d) towards the inside face of the side panel flaps (5, 9);

h. Folding the product of step g. at Fold line C;

i. Applying adhesive to outer surface of back base flap (8);

j. Folding front base flap (4) at fold H towards the back base flap (8) to secure the front and back base flaps (4, 8);

k. Loading frozen confection products into container, preferably one frozen confection per cavity formed from the inner panel (10), one or more separator panels (11) and distal separator flaps (13);

L. Folding the two top side panel flaps (14b, 14c) or corner flaps (17a, 17b) towards the inside face of the side panel flaps (5, 9);

m. Folding the product of step I. at Fold line D;

n. Applying adhesive to the outer surface of back lid flap (7) adjacent to fold D avoiding any perforated lines (19).

o. Ensure distal end of back top wall panel is in contact with front panel (2) adjacent to fold line G; and

p. Folding front lid flap (3) at fold line G towards back lid flap (7) to secure the front and back lid flaps (3, 7).

Auto-pop up means that force is applied to both side walls 3a and 3b in order to obtain a 3D shape; i.e. side walls 3a and 3b become orthogonal to the front panel (2) and back panel (6).

Experimental:

Method of manufacturing blank and container

Cardboard [MetsaBoard Pro FSB; 1 PE; 280GSM + 18gsm PE (One Side) = 298gsm; from Metsa] was cut on an Esko CAD Cutting table to obtain a blank cut and partial cut and creased according to design programmed into Esko CAD Cutting table apparatus. Wastage is removed and stripped to ensure apertures are open (i.e.: free from waste board). The blank is then folded and glued with a hot-melt adhesive (tecbond) applied via a standard 12mm Hot Melt glue gun, where required.

The container is assembled according the‘method of assembly’ described above.

Method of measuring leakage

Three frozen confection packaging blanks (1), as provided in figures 1 to 3, and a comparative example were assembled into frozen confection containers as provided in the above method. SOLERO™ Bio Peach frozen confection stick products (five lollies; Unilever) were placed inside each box with the stick-end of the frozen confection stick products at the lid end of the frozen confection container. The boxes were sealed and stored in a freezer at -18 for 24 hours. The frozen confection containers were removed from the freezers and held in various positions. The frozen confection containers were oriented so that the following features of the containers were in contact with a horizontal surface:

1. The fold between the side panel (5) and side panel flap (14d);

2. Back panel (6); 3. Side panel (5,9); and

4. Back base flap (8).

The frozen confection containers oriented in the given positions at 30 °C for 1 hour. Plastic containers collected liquid leaked from the frozen confection containers. The leakage obtained from the four frozen confection containers was combined and is presented in table 1.

The comparative frozen confection packaging blank (1) comprised four side panel flaps similar to 14a, 14b, 14c, 14d; however, the widths (corresponding to width L of the present invention) of all of these flaps were less than the width of the first and second side panel flaps (5, 9).

Table 1 : Leakage from frozen confection containers.

As demonstrated by the experimental examples, the frozen confection container provides a reduced leakage or leak-proof frozen confection container suitable for use as a multipack frozen confection container that can be used for in-home products; i.e. suitable for use as a carrier for transport of the frozen confection products for greater than ten minutes between a point of purchase and a freezer, e.g.: a domestic freezer, wherein at least one of frozen confection products held within the frozen confection container remains held within the container to be stored in the freezer for consumption at least ten minutes after storage.
