As is well known, hinge lid packets, also known as flip top packets, consist of a body portion having a frontpanel connected indirectly to a back panel and a lid portion hinged to the back panel. A conventional blank for these packets comprises an integral base panel intermediate the front and back panels, the shape of the unerected blank being such that the lid portion and the back base and front panels are all sequentially in line.

In packing machines for packing bundles of cigarettes into such blanks, each bundle is fed endwisc (i.e. axially with respect to the cigarettes) towards the back panel of a blank, so that the front panel can then be folded around the bundle in the first stage of the folding operation. However on some packing machines it has been found desirable for the bundles to be fed to the blanks sideways, i.e., transversely of the axes of the ciragettes.

According to the present invention there is provided a blank for a hinged lid packet having a body portion and a lid portion, the body portion comprising a back panel connected along a hinge line to the lid portion, a side panel connected to a side of the back panel perpendicular to the hinge line, and a front panel connected to said side panel opposite the back panel.

The invention also extends to a hinged lid packet made from such a blank.

A packet according to the invention will now be described by way of example only with reference to the accompanying drawings in which:

FIG. 1 is a perspective view of the packet, and

FIG. 2 is an outside view of the blank from which the packet is made.

The packet is made from a cardboard blank and comprises a lid portion hinged to a body portion about a hinge line I.

The body portion comprises a back panel 2, a front panel 3, a right hand side panel 4 (as viewed in FIG. 1) connecting the back and

front panels

2 and 3, and a left hand side panel consisting of an inner panel 5 and an outer panel 6. The base of the body portion, only shown in FIG. 2, comprises an outer panel 7 connected to the front panel 3, an inner panel 8 which is con nected to the back panel 2 and which overlies and is secured to he panel 7 in the erect packet, and flaps 9 and 10 extending from the

panels

4 and 5 respectively and which are secured to the inner panel 8.

The lid portion comprises a back panel 11 hinged about the line 1 to the back panel 2 ofthe body portion, a front panel 12, a top panel 13 connecting the back and front panels 11 and I2 and two inclined sides each consisting of an outer panel 14 extending from the ends of the front panel 12, and an inner panel 15 extending from the ends of the back panel I! and secured to overlie the outer panel 14.

A part of the front panel I2 is reinforced by a panel 16 which is reverse bent to from a free edge 17 and is secured to the inside of the front panel 12.

The edges between the top panel 13 and the two sides of the lid portion are closed by flaps 18 extending from the inner panels 15 and which are secured to the inside of the top panel 13.

As conventional, an inclined slit 19 is provided at each top corner of the back body panel 2. These slits allow flexing of the material below the hinge line to enable the erect lid to be swung more easily backwards, as shown in FIG. 1.

Secured within the body portion is a standard inner frame 20, shown chain dotted in FIG. 1. The inner frame projects upwards from the front panel 3 and the

sides

4, 5 and 6 and fits against the inside of the lid portion when closed to provide the normal locking action for the lid.

I claim:

1. A blank for a hinged lid packet having a body por tion and a lid portion, said body portion comprising a back panel connected along a hinge line to said lid portion, a front panel having a height smaller than said back panel, a first side panel connecting one side of said front panel to one side ofsaid back panel, a second side panel having the same width as said first side panel and connected to the other side of the said front panel, and a third side panel connected to the other side of said back panel and adapted in the erect packet to underlie and be secured to the inside of said second side panel, the top edge of each side panel being inclined so that in the erect packet the top edge of said side panel slopes from said back panel down to said front panel.

2. A blank according to claim I in which a short diagonal cut is formed in said back panel from each end of the hinge line, so as to facilitate flexure of said lid por tion about the hinge line.

3. A blank according to claim I further comprising a front panel for said lid portion, and a reinforcement panel extending from the end of said front panel for said lid portion remote from the hinge line, and intended in use to be reverse folded and secured against the inside of said front panel for said lid portion.

4. A blank according to claim 3 in which said reinforcement panel is of a depth smaller than the depth of said front panel for said lid portion.

5. A hinged lid packet made from a blank according to claim 1.

6. A packet according to claim 5 further comprising an inner frame secured to said body portion to project above said front panel and side panels of said body portion, said inner frame being adapted in use to retain said lid portion locked in the closed position.

7. A hinged lid packet having a body portion and a lid portion, said body portion comprising a back panel connected along a hinge line to said lid portion, a front panel having a height smaller than said back panel, a first side panel connecting one side of said front panel to one side of said back panel, a second side panel having the same width as said first side panel and connected to the other side of said front panel, and a third side panel connected to the other side of said backpanel, wherein said back panel lies in a plane parallel to said front panel, said first side panel lies in a plane parallel to said third side panel, said plane parallel to said front panel being perpendicular to said plane parallel to said third side panel, said third side panel underlies and is secured to the inside of said second side panel, and the top edge of said side panel is inclined and slopes from said back panel down to said front panel.

8. A hinged lid packet according to claim 7 further comprising a front panel for said lid portion, and a reinforcement panel extending from the end of said front panel for said lid portion remote from the hinge line, wherein said reinforcement panel is reverse folded and body portions, said inner frame being adapted in use to retain said lid portion locked in the closed position.

11. A hinged lid packet according to claim 7 in which a short diagonal cut is formed in said back panel from each end of the hinge line, so as to facilitate flexure of said lid portion about the hinge line
