Abstract

A flip top cigarette pack comprises a cover(3) and a pack body(2). Top of the rear wall of the pack body is connected with bottom of the rear wall of the cover. Each top of two side walls of the pack body is an arc shape. Each bottom of two side walls of the cover is an arc shape corresponding to the shape of that of the top. The cigarette pack improves the loading type of the combination of the cover and the pack body, avoids the clearance difference generated by two sides of the cigarette pack after finishing and improves the quality of pack and the percent of pass.

Description

Flip cigarette case with flip cover at the bottom of concave side wall

The invention relates to the design of a package, in particular to a clamshell cigarette package. Background technique

The clamshell box is a widely used cigarette package, and the clamshell box is characterized in that the (thin) cardboard is cut into a blank by a die-cutting board and packaged into a cigarette box by a packaging machine.

Known clamshell cigarette cases generally include a box body and a flip cover, the box body being composed of a front wall, a rear wall, a bottom wall and double side walls. The flip cover is composed of a front wall, a top wall, a rear wall and double walls. The top of the rear wall of the casing is connected to the bottom of the rear wall of the flip cover, and the front wall of the casing and the top of the double side wall are respectively engaged with the front wall of the flip cover and the bottom of the double side wall. Wherein, the front wall of the box body and the front wall of the flip cover are horizontally straight, and the double side walls of the box body and the double side wall of the flip cover are respectively inclined lines. In the process of packaging the blank from the blank, the conventional cigarette case is liable to cause gap difference on both sides of the cigarette case after molding, that is, the side walls of the box body and the flip cover do not match well, which affects the quality of the package. Disclosure of invention

SUMMARY OF THE INVENTION The object of the present invention is to provide a novel flip-top cigarette case for improving the force of the combination of the flip cover and the box body, and to avoid the gap difference between the two sides after the cigarette case is formed.

To achieve the above object, the clamshell cigarette case of the present invention comprises a case body and a flip cover, and a top of the rear wall of the case body is connected to a bottom of the rear wall of the flip cover, wherein the tops of the double side walls of the case body respectively In the shape of an arc, the bottoms of the double side walls of the flip cover are respectively curved corresponding to the top of the side wall of the casing. The arc shape of the top of the double side wall of the box body may be a convex arc shape. Correspondingly, the arc shape of the bottom side of the side wall of the flip cover may be a concave arc shape. The barrel of the drawing is to be explained

Figure 1 is a schematic view of an embodiment of the present invention;

Figure 2 is a schematic view of the blank of the cigarette case of Figure 1 prior to packaging;

among them:

1 - Cigarette case 1, - Box blank

2 : box

3 - Flip cover

4 - the back wall of the box

5 - Flip back wall

6 - Side wall of the box 7 - Flip side wall to achieve the best mode of the invention

1 and 2, the flip cigarette case 1 comprises a case 2 and a flip cover 3, the top of the rear wall 4 of the case 1 and the bottom of the rear wall 5 of the flip cover 3 are connected at C, two of the case 2 The tops of the side walls 6 are respectively curved A, and the bottoms of the two side walls 7 of the flip cover 3 are respectively curved A' corresponding to the top of the side wall 6 of the casing 1. The arc A and the arc A' have the same arc degree, and the radius of the arc is 30 mm, so that the casing 1 and the flip cover 2 can be fastened. The blank Γ shown in Fig. 2 can be obtained only by changing the die-cutting plate, and the cigarette case shown in Fig. 1 can be packaged without changing the working procedure of the existing packaging machine.

In other embodiments of the present invention, the curved shape A at the top of the side wall 6 of the casing may be either an upper circular arc shape or a lower circular arc shape; correspondingly, the curved shape A at the bottom of the flip side wall 7 ' It can be either a circular arc of the lower W or a circular orphan of the upper convex.

In order to make the appearance of the cigarette case 1 more beautiful, in other embodiments of the present invention, the melon shape A at the top of the side wall 6 of the box body may be designed to be a combination of an upper convex arc and a concave circular arc. The arc shape, correspondingly, the arc A' at the bottom of the flip side wall 7 is designed as a combined arc shape formed by a concave arc and an upwardly convex arc. In short, as long as the portion is designed in a circular arc shape, the force between the casing and the flip cover can be changed, and the packaging quality and yield of the cigarette case can be improved, and the object of the present invention can be achieved. Industrial applicability

The technical effect of the invention is: changing the singularity of the current cigarette case, improving the aesthetics of the package, increasing the novelty of the package; changing the die-cut shape of the existing cigarette case package, and forming the side of the opening after molding In the form of an arc, the change is only required to change the die-cut version of the package sheet. It does not affect the existing method when packaging on the packaging machine, and does not need to change the packaging equipment; this change makes the combination of the packaged box and the flip cover. The method is improved, the gap difference is formed on both sides of the cigarette box after molding, the quality of the package is improved, and the yield of the finished product is improved.
