Description

FIELD OF THE INVENTION

This invention relates to a novel device being a package for containing an article, particularly an article being a toothpaste tube.

BACKGROUND OF THE INVENTION

It is well known to package toothpaste tubes in tetragonal card packages having a relatively long length dimension, a rectangular (the term herein includes square and trapezoidal) cross section as cut across the longitudinal direction and relatively shorter width and height dimensions. Such packages are normally made by cutting out a blank of the foldable material with creases, apertures, adhesion flaps etc. in appropriate positions. Generally the toothpaste tube is accessed via a folding flap closure at a longitudinal end of such a package. It is known to provide such packages with recessed regions, e.g. to support a toothpaste tube within the package, for example as in EP-A-0 465 257; U.S. Pat. No. 2,980,242; U.S. Pat. No. 4,925,088; EP-A-0 611 701; U.S. Pat. No. 4,909,385 and JP-A-2001/139019.

A package of this type for a toothpaste tube is sold by the applicant under the name AQUAFRESH Advanced, which has a recessed region provided primarily for the aesthetic impact of text printed on the recessed region. In this AQUAFRESH Advanced package the recessed region is provided by folding six panels to form the package, i.e. four forming the outer walls of the package, one of these four having an aperture therein, with an internal panel forming a recessed wall visible through the aperture.

This use of six panels is an excessive use of materials. It is an object of this invention to provide a package suitable for a toothpaste tube requiring less material than the known AQUAFRESH Advanced package, but having a similar aesthetic effect.

SUMMARY OF THE INVENTION

According to this invention a package for containing a product therein and made of a foldable material has a rectangular cross section as cut across its length direction and has an external top panel and external side panels arranged circumferentially around the perimeter of the rectangular cross section, with folded side edges between adjacent pairs of said panels, and having a width direction, and a height direction perpendicular to the width direction across said rectangular cross section, and having its longitudinal direction perpendicular to both the width and height directions, characterized by:

the top panel comprising two longitudinally disposed part top panels with a gap longitudinally between them, the gap being bridged by a recess panel extending across the whole width of the package and being recessed in the height direction from the top panel,

the top panel being formed integrally with a widthways adjacent external side panel and connected thereto directly by a top folded edge, and attached to a side panel widthways opposite said side panel,

the recess panel also being formed integrally with an external side panel and connected integrally thereto directly by a recess panel folded edge parallel to the top folded edge and distanced in the height direction from the top folded edge, and attached to a widthways opposite external side panel.

The present invention enables a recessed panel to be formed with less material than is required in the known AQUAFRESH Advanced package, but with a similar aesthetic effect.

DETAILED DESCRIPTION OF THE INVENTION

The package preferably has dimensions which enable it to closely conform to a toothpaste tube therein. Preferably the package has a conventional folding end closure. Preferably the foldable material is cardboard.

The respective top and side panels are suitably longitudinally elongate rectangular shapes. The folded edges between adjacent pairs of side panels are suitably right angle folds.

The side panel to which the recess panel is attached preferably has a notch therein of a depth in the height direction corresponding to the distance in the height direction of the recess panel from the top panel.

In a preferred embodiment the top panel and recess panel are formed integrally with the same widthways adjacent external side panel and connected thereto directly by respectively the top folded edge and the recess panel folded edge parallel to the top folded edge, and are both attached to the same widthways opposite said side panel.

The recess panel may be any suitable shape, for example rectangular, circular, or oval, though the first and second recess panel edges are preferably formed along straight line edges of the panel.

Preferably the recess panel is planar and has its plane parallel to the plane of the top panel. The recess panel may be spaced in the height direction from the top panel by any distance which is considered to be aesthetically suitable, typically 2-3 mm.

The invention further provides a blank made of a foldable material for folding to make a package of this invention.

One form of such a blank comprises:

a sheet of a foldable material comprising a top leaf and integral sequentially breadthways adjacent first, second and third side leaves, corresponding to the respective top panel and side panels of the package, with foldable creases extending in a longitudinal direction between adjacent pairs of said leaves, said leaves having breadth directions perpendicular to the longitudinal direction, and corresponding to the width and height directions of the package, characterized by:

the top leaf comprising two longitudinally disposed part top leaves, a recess panel leaf located longitudinally between said part top leaves with slots between the recess panel leaf and each part top leaf,

the top leaf being formed integrally with a widthways adjacent side leaf and connected thereto directly by a first foldable crease,

the recess panel leaf also being formed integrally with the same widthways adjacent side panel and connected integrally thereto directly by a second foldable crease parallel to the first foldable crease and distanced in the breadth direction from the first foldable crease in the direction toward the widthways adjacent side leaf.

Suitably in this blank, in the third side leaf there is a notch in the edge of the side leaf remote from the top leaf, having a notch edge parallel to the first foldable crease, and distanced from the edge of the side leaf at a distance corresponding to the distance in the breadth direction the second foldable crease is from the first foldable crease.

An alternative blank comprises:

a sheet of a foldable material comprising a top leaf and integral sequentially breadthways adjacent first, second and third side leaves, corresponding to the respective top panel and side panels of the package, with foldable creases extending in a longitudinal direction between adjacent pairs of said leaves, said leaves having breadth directions perpendicular to the longitudinal direction, and corresponding to the width and height directions of the package, characterized by:

the top leaf comprising two longitudinally disposed part top leaves, with a gap longitudinally between them,

the top leaf being formed integrally with a widthways adjacent side leaf and connected thereto directly by a first foldable crease,

the third leaf having a third leaf edge remote from the top leaf, the recess panel leaf being formed integrally with the third side leaf and connected integrally thereto directly by a second foldable crease parallel to the first foldable crease and distanced in the breadth direction from the third leaf edge in the direction toward the top leaf.

Suitably in this alternative lank, in the first side leaf, breadthways adjacent to the top leaf there is a notch in the edge of the side leaf, having a notch edge parallel to the first foldable crease, and distanced from the edge of the side leaf in the direction away from the top leaf at a distance corresponding to the distance the second foldable is from the third leaf edge.

The above-mentioned slots may be cuts having as small a width as is feasible.

The blank may also include generally conventional flaps by which the leaves may be stuck to each other by a conventional adhesive, and/or to form a conventional folding end closure.

Such a blank may be made on an industrial scale from a sheet of the foldable material using generally conventional cutting and creasing machinery.

The package of the invention may be made from such a blank using a conventional folding operation. This may be done on an industrial scale using folding machinery.

The invention will now be described by way of example only with reference to the accompanying drawings.
