Cigarette case comprising integrated combined self-sealing inner package

Abstract

The invention provides a cigarette case comprising an integrated combined self-sealing inner package. The cigarette case comprises an outer case and the inner package; the outer case is arranged outside the inner package; the inner package is formed by integrally folding a P&G double-layer composite material base material through a special processing technology, the base material comprises an outer layer base material body and an inner layer base material body, a semi-penetrating inner package uncovering layer outline cutting line and a curve notch for preventing excessive tearing are formed in the middle of the outer layer base body, and a taking-out opening outline cutting line penetrating the double-layer base material in a half mode is arranged in the inner package uncovering layer outline cutting line; an adhesion region is arranged at the outer side of the front end of the inner package uncovering layer outline cutting line, the adhesion region and the inner side of an outer case cover are bonded permanently, when the outer case cover is opened, the inner package uncovering layer outline cutting line is broken to form an inner layer uncovering layer, and an inner package taking-out opening is formed by the taking-out opening outline cutting line; when the outer case cover is closed, self-sealing is formed on the inner package taking-out opening by the inner layer uncovering layer. The cigarette case is simple in structure, convenient to process, wholly attractive, good in dampproof effect, healthy, environmentally friendly, high in durability and safe and reliable in the using process.

Description

technical field [0001] The invention relates to the field of packaging for daily necessities, in particular to a cigarette case comprising an integral composite self-sealing inner package. Background technique [0002] Cigarette boxes currently on the market mainly include hard boxes and soft boxes, which are generally composed of two parts: an outer packaging box and an inner packaging. The outer packaging is generally an easy-to-print paper box or other soft and hard packaging boxes, while the inner packaging is generally composed of aluminum foil, transfer aluminized paper or other flexible and foldable substrates. When consumers need to smoke cigarettes, they usually need to open the outer packaging box and the inner packaging separately. The opening process is more complicated. At the same time, the inner packaging is not easy to reseal after opening, which may easily cause the cigarette aroma to be lost, damp or dry. It is easy to cause pollution, thus affecting the u...

AI Technical Summary

Problems solved by technology

However, in terms of structure, the weakened line of the cover sheet of this technical solution runs through the entire top of the inner package, and adopts the method of linear laser cutting (perforation). In the process of repeatedly opening and taking out the outer box cover, the cover sheet is easily torn and damaged along the weakening line, which affects the airtightness of the inner package, causes the cigarette to be damp or dry, and affects the appearance of the cigarette box; at the same time, The downward extension distance of the weakened line of the cover sheet in this technical solution is not limited, and when the downward extension distance of the cover sheet is greater than 2.5 cm, it will extend to the lower end of the opening of the cigarette outer box, resulting in failure to open or forced opening. Once again, it cannot be closed, resulting in defective products or affecting the appearance of the cigarette box; in terms of blank forming, because this technical solution adopts a folding method similar to that of cigarette soft box packaging, the folding method is complicated, and it needs to be processed on the cigarette packaging machine It is formed by heating bonding or glue bonding, and when the heating temperature is low, the bonding between the films cannot be formed or the bonding is not strict. Chemicals and bad smells, which affect the smoking quality of cigarettes

When using external glue for bonding, it will increase the process links, resulting in an increase in cost; at the same time, when making the weakened line, the technical solution uses laser cutting or laser drilling, which has high equipment costs and processing costs; In terms of material composition, since the blank in this technical solution is made of no less than three layers of materials, a large amount of adhesive is required to form an adhesive layer, and it is easy to add too many chemical substances, causing odor

At the same time, the blank materials used in this technical solution are all made of film materials. Due to the strong toughness of film materials, it is difficult to fold and form them, which increases the difficulty of packaging technology and reduces the efficiency of packaging.
