Description

FIELD OF THE INVENTION

The present disclosure relates to a package for consumer goods and particularly to a re-sealable cigarette pack.

BACKGROUND

Numerous approaches have been made for packaging consumer goods. In the case of cigarettes, for example, packages are designed to preserve the flavor and freshness of the consumer goods and also protect the goods from contamination. Known packages employ outer containers having a hinged lid providing access to an inner container with an opening for accessing the consumer goods. The outer containers are generally formed of a rigid paperboard, cardboard, or other suitable material. The inner container is generally formed of a material or combination of materials having substantially less rigidity than the outer container. For example, the inner container is known to be formed of paperboard, packing material, paper, and/or aluminium. In known designs, a label with a tacky substance for sealing and re-sealing can be used to cover the opening of the inner container.

Depending on machine tolerances, the permanent adhesive 30 and the re-stick adhesive 32 are preferably applied to the pull tab with an adhesive-free gap 34 between them. The gap 34 provides an air vent which allows air to escape from inside the inner box when the pull tab 10 closes the extraction opening in the inner frame. For example, the gap 34 can be about 1 mm wide and located about 3 mm from the location of the extraction opening (illustrated by dotted lines 18). The line of perforations 20 can be located about 2 mm below the location of the extraction opening and about 8 mm above a lower edge of the pull tab. As an example of the pull tab and extraction opening dimensions, the extraction opening can be about 30 mm wide and about 32.5 mm long and the pull tab 10 can be about 50 mm wide and about 65 mm long.

As shown in FIG. 10C, the re-stick adhesive 32 covers the pull tab except along the lower side edges 34, 36 and bottom edge 38 of the pull tab 10. For example, the re-stick adhesive can be applied in a pattern which has a weaker adhesion force at the bottom edge 38 of the pull tab 10 and a stronger adhesion force above the line of perforations 20. The line of perforations 20 forms a connecting tab 40 which is permanently attached to the inside of the hinged lid of the outer box. Thus, when the hinged lid is opened, the re-stick adhesive 32 on the underside of the connecting tab 40 provides a weaker adhesion force holding the pull tab 10 to the outer surface of the inner frame than the remainder of the re-stick adhesive above the line of perforations 20.

In an embodiment, the lower portion of the re-stick adhesive can be applied with a saw tooth pattern 42 extending across the connecting tab 40. In the saw tooth pattern shown in FIG. 10C, four triangular regions of re-stick adhesive cover about 40 to 60% of the connecting tab 40. Preferably, the area of re-stick adhesive is smallest (e.g., minimum) at the bottom edge 38 of the pull tab, larger (e.g., midpoint) at the line of perforations 20 and largest (e.g., maximum) at a location above the line of perforations 20. For example, the re-stick adhesive 32 can begin to decrease in area at about 16 mm above the bottom edge 38, decrease in area by about 50% or less at the location of the line of perforations 20, and reach a minimum at about 1 mm from the bottom edge 38 of the pull tab 10.

FIG. 10D shows the pull tab 10 with a piece of foil/paper 44 adhered to the re-stick adhesive 32 so as to cover the location of the extraction opening (illustrated with dotted lines 18). For example, the foil/paper piece 44 can be a piece of bundle wrap typically used to wrap a bundle of cigarettes and the piece 44 is adhered to the pull tab 10 with the paper side of the piece 44 exposed. When the pull tab 10 is applied to an inner package containing cigarettes, the paper side of the piece 44 will be in contact with ends of the cigarettes. As an example of part dimensions, the piece 44 can be sized to extend about 2 mm beyond the extraction opening (illustrated by dotted lines 18). FIG. 10E shows the piece 44 prior to being attached to the pull tab 10. In the case of an extraction opening about 30 mm wide and about 32.5 mm long, the piece 44 can be about 34 mm wide and about 36.5 mm long. The extraction opening can have rounded corners (as illustrated by the dotted lines 18 in FIG. 10D) and the piece 44 can also have rounded corners as shown in FIG. 10E.

The container can have various design features. For example, the consumer goods can comprise a bundle of loose smoking articles and the pull tab can comprise a flexible sheet of polymer material having re-stick adhesive on the underside thereof wherein the paper liner comprises a substantially square piece of bundle wrap adhered to the pull tab by the re-stick adhesive such that a paper side of the bundle wrap is exposed and faces the smoking articles in the inner package.

The pull tab can be rectangular in shape and cover at least 90% of a width of the front, top and back walls, the pull tab including a rectilinear line of weakening extending across the pull tab at a predetermined distance from a bottom edge of the pull tab such that a portion of the pull tab below the line of weakening forming a rectangular connecting tab adhered to the inner surface of the hinged lid with the permanent adhesive.

In a preferred embodiment, the pull tab can be attached to the hinged lid by permanent adhesive attaching an outer surface of the pull tab to the inner surface of the hinged lid and the pull tab is attached to the inner package by permanent adhesive attaching an inner surface of the pull tab to an upper portion of the back wall of the inner package. The pull tab can comprise a film of polyethylene terephthalate (PET) and the paper liner can comprise a piece of paper laminated to metal foil.

In an embodiment, the container includes an outer box having the size of a traditional cigarette pack. For instance, the outer box can have a height of about 3 to 4 inches, a width of about 2 to 2.5 inches, and a thickness of about 1 to 1.25 inches with the inner package sized to fit snugly within the outer box. For example, the outer box can be about 88 mm high, about 56 mm wide and about 23 mm thick, with the inner package being about 86 mm high, 55 mm wide, and 22 mm thick. The size of the container will depend on the size of the consumer goods. Where the consumer goods are cigarettes, the size of the container can be designed to accommodate 20 cigarettes having lengths of 40 to 180 mm and diameters of 4 to 9 mm. Thus, the outer dimensions of the container will be slightly larger than the dimensions of the cigarette bundle, e.g., the height, width and thickness of the container can be at least 1 mm larger in each direction than the dimensions of an unwrapped cigarette bundle.

The pull tab can be a rectangular shaped sheet with a width of about 50 mm and a length of about 65 mm. The paper liner can be a rectangular shaped sheet with a width of about 34 mm and a length of about 36 mm. The pull tab can include a rectilinear line of weakening located about 8 mm from one end of the pull tab to form a connecting tab at the bottom of the pull tab.

The pull tab can include one or more machine readable markings on an inner surface and/or outer surface. For example, the pull tab can include a large black mark extending completely across the upper end of the underside of the pull tab and smaller black marks at opposite lower corners on the upper side of the pull tab.

The paper liner can have an outer periphery which extends about 2 mm beyond an outer periphery of the opening. The pull tab can be permanently adhered to the back wall of the inner package. The opening can have a width of about 30 mm and a depth of about 16 mm in the top wall of the inner frame and a width of about 30 mm and a depth of about 16 mm in the front wall of the inner frame. The pull tab can also include a connecting tab defined by a rectilinear line of 2.5 mm long perforations located about 8 mm from a lower edge of the pull tab.

The connecting tab can include an adhesive-free area such as an area of deadened adhesive and a re-stick adhesive area on an inner surface thereof, the adhesive-free area decreasing in size in a direction away from a lower edge of the connecting tab and the re-stick adhesive area decreasing in size in a direction towards the lower edge. The permanent adhesive can be located in first and second zones, the first zone located at an upper portion of the inner surface of the pull tab and the second zone located at a lower portion of an outer surface of the pull tab, the second zone of permanent adhesive attaching the connecting tab to an inside surface of the hinged lid, the re-stick adhesive area forming part of a single zone of re-stick adhesive extending from the connecting tab to the first zone of permanent adhesive.

In various design variations, (a) the pull tab can comprise a piece of polymer film having a substantially rectangular shape with parallel upper and lower edges and parallel side edges, the side edges having a length greater than a width of the upper and lower edges, (b) the first zone of permanent adhesive can have a rectangular shape extending about 30% of the length of the pull tab and the single zone of re-stick adhesive can have a substantially rectangular shape extending about 70% of the length of the pull tab, (c) the first zone of permanent adhesive can be separated from the single zone of re-stick adhesive by a uniform gap about 1 to about 2 mm wide, (d) the single zone of re-stick adhesive can include an upper border parallel to the upper edge of the pull tab, side borders parallel to the side edges of the pull tab, and a lower border which provides a decreasing area of re-stick adhesive in a direction towards the lower edge of the pull tab, (e) an adhesive-free border can extend completely around the inner surface of the pull tab with the adhesive-free border extending no more than about 2 mm from the outer periphery of the pull tab, (f) the adhesive-free gap can extend completely across the pull tab to the adhesive-free border on opposite sides of the pull tab, and/or (g) the pull tab can include at least one machine readable marking on an inner and/or outer surface thereof.

In an embodiment, the pull tab can include a line of weakening such a line of perforations extending transversely across the pull tab at a location corresponding to the upper back edge of the inner package, i.e., the edge between the back panel and the top panel. The first zone of permanent adhesive can extend over the line of weakness such that when the pull tab is attached to an inner package, the line of weakness is aligned with the top back edge of the inner package and the first zone of permanent adhesive contacts the an upper portion of the back panel and a portion of the top panel adjacent the back panel. As an example, the line of weakening can be arranged such that about 80% of the first zone of permanent adhesive is located on the back panel of the inner package and about 20% of the first zone of adhesive is located on the top panel of the inner package.

In another embodiment, the pull tab can include re-seal adhesive covering the connecting tab with one or more areas of the re-seal adhesive deadened to promote peeling of the pull tab when the outer box is opened. FIGS. 11A-H show variations of where the re-seal adhesive 32 can be deadened.
