Crushable pack

A crushable pack comprising a plurality of interconnected side panels which define therein a volume for receiving a product, the pack having an opening at one end, which opening is at least partially closed by a non-return end closure mechanism which operates to allow the product to be inserted fully past the end closure mechanism into said volume and to prevent subsequent removal of the product back past said end closure mechanism, the end of the pack opposite said one end being closed sufficiently to prevent removal of the product and the pack having a lengthwise axis extending between the two ends, wherein said end closure mechanism comprises one or more end flaps disposed within said volume and hingedly connected to respective side panels, said one or more end flaps being hingable in one direction further into said volume to allow said insertion of said product and being prevented from hinging in the other direction without distortion out of said volume thereby to prevent said removal of the product, the hinge axis of the or each end flap being substantially perpendicular to said lengthwise axis of the pack and wherein the pack is compressible to reduce said volume in use of the pack,

• wherein said end closure mechanism comprises one end flap, the end flap being hingedly connected to one of said side panels and being disposed inside said volume, wherein the end flap is dimensioned such that at least part of the end flap is too large to enable the end flap to hinge about said one side panel without distortion of the end flap or the side panels into a position outside of said volume, whereby the end flap can hinge further into the volume to enable said insertion of said product into the pack via said opening and then resiliently returns to a position preventing said removal of said product via said opening, and
• wherein the interconnected side panels of the pack include three planar side walls such that the volume is triangular in section and the opening is triangular, the end flap being connected to one of said side walls.

• wherein the interconnected side panels of the pack include four planar side walls such that the enclosed volume is rectangular in section and the opening is rectangular, the end flap being connected to one of said side walls which is spaced from an oppositely disposed side wall, and
• wherein said end flap only extends partially along the side wall to which it is hingedly connected and is centrally disposed between the side walls adjacent and perpendicular to said one side wall.
