Description

Technical Field

[0001] The utility model relates to the technical field of tobacco packaging, in particular to an inner lining film for manually easy-to-open tobacco packaging. Background Art

[0002] Tobacco is highly sensitive to the environment and, in contact with the atmosphere, its organic properties tend to change with changes in humidity (by losing or absorbing excess moisture) or due to the evaporation of volatile substances with which the tobacco is saturated (especially in the case of aromatic cigarettes treated with flavorings such as cloves).

[0003] The existing packaging mainly includes a box body, a hinged box cover, a foil inner package, etc. After opening the box cover, the foil inner package is partially torn off to achieve the purpose of opening the cigarette. After use, the box cover is closed, and the sealing effect is poor. If the cigarettes are not used up immediately after opening the package, the organic properties of the remaining cigarettes will be significantly deteriorated. Utility Model Content

[0004] The utility model aims to provide an inner lining film for manually easy-to-open tobacco packaging to solve the problems raised in the above-mentioned background technology.

[0005] The technical solution of the utility model is: a lining film for manually easy-to-open tobacco packaging, comprising a box body, a box cover hinged to one side of the top end of the box body, a hard lining arranged at the front end of the top opening of the box body, a box-shaped foil lining bonded to the inside of the box body, a flip portion arranged at the top end of the foil lining, an extension portion integrated with the front side of the foil lining arranged at one end of the flip portion close to the box body opening, a tear line arranged between the extension portion and the foil lining, and an adhesive component arranged at the side of the extension portion away from the flip portion.

[0006] The effects achieved by the above components are: the tear line can facilitate the user to tear the extension part from the foil lining after the box cover is flipped open, and the torn extension part is bonded to the front inner wall of the box cover by using the adhesive assembly, and the flip part is fitted with the top inner wall of the box cover. The flip part and the extension part can seal the cigarettes in the closed state of the box cover, and cooperate with the secondary sealing effect of the box cover to improve the sealing effect of the cigarettes.

[0007] Preferably, the adhesive assembly comprises an adhesive portion connected to the extending portion, an outer side of the adhesive portion is coated with an adhesive strip, and a release film strip is adhered to the outside of the adhesive strip.

[0008] The effect achieved by the above components is: the rubber strip on the bonding part can be protected by the release film strip. After the release film strip is torn off from the bonding part, the bonding part is bonded to the inner wall of the front side of the box cover by the rubber strip, so that the flip part and the extension part can be opened and closed synchronously with the box cover at the top of the box body, which is convenient to use.

[0009] Preferably, a kneading portion is provided on the end side of the release film strip.

[0010] The effect achieved by the above components is that the release film strip can be easily torn off from the adhesive strip through the kneading portion.

[0011] Preferably, a notch with an edge slightly smaller than the bonding portion is formed at the bottom end of the tear line on the foil lining.

[0012] The effect achieved by the above components is that the notch makes it easier for users to identify and open the extension part.

[0013] The utility model provides an inner lining film for manually easy-to-open tobacco packaging through improvement, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, the utility model can facilitate the user to tear the extension part from the foil lining after the box cover is flipped open by means of the tear line, and the torn extension part is adhered to the inner wall of the front side of the box cover by means of the adhesive assembly, so that the flip part is in contact with the inner wall of the top of the box cover, and the flip part and the extension part can seal the cigarettes in the closed state of the box cover, and cooperate with the secondary sealing function of the box cover to improve the sealing effect of the cigarettes;

[0015] Secondly, the utility model can protect the adhesive strip on the bonding part through the release film strip. After the release film strip is torn off from the bonding part, the bonding part is bonded to the front inner wall of the box cover with the adhesive strip, so that the flip part and the extension part can be opened and closed synchronously with the box cover at the top of the box body, which is convenient to use.
