Description

FIELD OF THE INVENTION

[0001] The present invention relates to a detergent product comprising a flexible box bag, laundry detergent powder and a scoop. The flexible box bag comprises a two dimensional opening means that is capable of forming a two dimensional planar opening, which when combined with the other box bag features provide easier access to the internal volume for the consumer to scoop and dose laundry detergent powder from the flexible box bag during the laundering process.

BACKGROUND OF THE INVENTION

[0002] Packaging for detergent powder, especially laundry detergent powder, typically comes in the form of a flexible bag or a more rigid box. Flexible bags have the advantage of being more easily handled by the consumer during the laundering process, and are also more efficient in terms of transport and storage. However, the rigid box have the advantage of being easier to dose laundry powder from during the laundering process, especially when using a scoop. In addition, rigid boxes have greater shelf impression to the consumer. Detergent manufacturers continue to seek flexible bags having the ease of handling, and transport and storage efficiency, but also having a good shelf impression of a box, and being easy to scoop and dose laundry powder from during the laundering process.

[0003] The Inventors provide a flexible box bag that overcomes these problems.

[0006] Flexible box bag: The flexible box bag comprises six rectangular panels: top panel, bottom panel, front panel, back panel and two side panels. The six rectangular panels are joined together so as to form an inner cuboidal volume inside the flexible box bag. The cuboidal volume is a cuboid. Suitable cuboids include square cuboids and rectangular cuboids. Preferably, the cuboidal volume is a rectangular cuboidal volume. Each of the top panel and bottom panel comprise a front horizontal edge, a back edge and two side edges. Each of the front panel, back panel and two side panels comprise a top edge, a bottom edge, and two side edges. The length of the two side edges of back panel are longer than the length of the two side edges of the front panel. The front edge of the top panel joins the top edge of the front panel. The back edge of the top panel joins the top edge of the back panel. The front edge of the bottom panel joins the bottom edge of the front panel. The back edge of the bottom panel joins the bottom edge of the back panel. The side edges of the top panel join the top edges of the side panels and part of the side edges of the back panel. The top panel comprises a two dimensional opening means that is capable of forming a two dimensional planar opening. The laundry detergent powder and scoop are both contained within the inner cuboidal volume.

The laundry detergent powder and scoop are inserted into the inner cuboidal volume by passing through a filling opening that is formed between the back edge of the top panel and top edge of the back panel. The back edge of the top panel and top edge of the back panel are joined together in such a manner as to close the filling opening to form the flexible box bag and detergent product. Typically, after it is filled, the interim flexible box bag is sealed by a weld seal.

[0100] The flexible box bag may be made from at least two different webs of film. For example, a first film may form the top panel, bottom panel, back panel, and front panel, and a second film may form the side panels. In this manner, the flexible box bag may have transparent side panels.

[0101] Typically, the laundry detergent powder is inserted into the inner cuboidal volume prior to the scoop. Also, settling plates may be used to slightly bury the scoop in the powder, this improves the stability of the detergent product.

[0102] The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value.
