Benefits of technology

[0014]An object of the present invention is to provide a hinge lid package, for example a cigarette package, that requires less force to open and close than conventional hinge lid packages while preventing the occurrence of package “smiling”. In accordance with an aspec...

Problems solved by technology

There are several problems that occur with extended use of prior art hinge lid cigarette packages.
Such problems include damage to the paper-board material as a result of repeated openings and closings of the package lid and “smiling” which is defined in the art as a “popping open” or slight separation of the lid away from a fully closed position.
However, although the curved hinge lid reduces the occurrence of “smiling” the package becomes difficult to open and close due to the curvature of the lid perimeter.
This results in damage to the cigarette package itself, for example ripping and tearing, as well as damage to the contents (cigarettes) housed within the package.
Another problem associated with prior art cigarette packages is that they can be difficult to open, and excessive force is often required to open the package l...

Package “Smiling”

[0151]The following test was designed in order to test the occurrences of package “smiling”. Measurements of the degree of smiling were completed on cigarette packages according to the present invention, including packages comprising: (i) a cam panel only; (ii) a cam panel and improved latching tab only; and (iii) a cam panel, improved latching tab, improved inner frame and a raised pivot axis. Conventional cigarette packages currently on the market, which did not contain any of the four improvements described herein, served as controls.

[0152]Each package was dropped from an elevation of 10 cm six times, and the degree of smiling measured with a ruler. In each case the package was dropped so that it would land with its back panel 32 facing downwards. The gap or opening between the bottom edge 56 of the lid front panel 50 and the top edge 36 of the box front panel 30 was considered to be the smile, as illustrated in FIG. 32B. Following the initial drop and after each...

Required Package Opening Force

[0155]The following test was used to determine the degree of opening force required to open a cigarette package. Again, measurements of the degree of force required to open a package were completed on cigarette packages according to the present invention, including packages comprising: (i) a cam panel only; (ii) a cam panel and improved latching tab only; and (iii) a cam panel, improved latching tab, improved inner frame and a raised pivot axis. Conventional cigarette packages currently on the market, which did not contain any of the four improvements described herein, served as controls. The force required to open a package was measured a total of six times for each package using a conventional Packaging corporation of America (PCA) score bend tester as illustrated in FIG. 33(A-C).

[0156]Briefly, packages were placed in a holder so that box part 10 was immobile, and lid 20 was clamped either on one side (as in most tests) or in the middle (FIG. 33A). Th...

Latching Tab Configurations

[0158]The following inner frame and package blank new profiles were tested in different combinations on a Focke 350S high-speed hinge lid packer:

Controls:

[0159]a standard inner frame profile (STD)

[0160]a standard box part blank (STD)

Test Materials:

[0161](As depicted in FIG. 36)[0162]Inner frame “A” with front top corners cut-off and a latching tab profile “A”[0163]Inner frame “B” with front top corners cut-off and a latching tab profile “B”[0164]Inner frame “C” with front top corners cut-off and a latching tab profile “C”[0165]Inner frame “D” with front top corners cut-off and a latching tab profile “D”[0166]Inner frame “E” with front top corners cut-off and a latching tab profile “E”[0167]Package blank 1, having raised pivot axis, standard inner frame, standard latching tab, no cam panel[0168]Package blank 2, having raised pivot axis, standard inner frame, standard latching tab, lid inside panel have a non-engaging curved profile.

Abstract

The present invention pertains to hinge lid packages, for example cigarette packages, with features that reduce the force required to open and close the package, keep the lid tightly closed when not in use and/or improve the luxurious feel of the package during opening and closing, in comparison to similar packages that do not include these features.

Description

FIELD OF THE INVENTION[0001]The present invention pertains to the field of hinge lid packages and to blanks for making such packages. In particular, the present invention pertains to a hinge lid package with good opening and closing capabilities.BACKGROUND[0002]In the past, considerable effort has been invested in producing cigarette packages that are lightweight, easy to open and close and which are aesthetically pleasing to the eye.[0003]Conventional hinge lid cigarette packages are well known in the art and are usually produced from a either a single blank or two blanks as outlined in U.S. Pat. No. 6,276,600, U.S. Pat. No. 5,586,648 and U.S. Pat. No. 5,553,773 and constructed of paperboard substrate which may be coated with a fluidized mixture of finely particulated minerals and binders resulting in a smooth luxurious appearance.[0004]There are several problems that occur with extended use of prior art hinge lid cigarette packages. Such problems include damage to the paper-board ...
