Abstract

The roof-type composite paper liquid beverage packaging box belongs to the technical field of food packaging boxes. In order to prevent leakage from the bottom of the beverage box, the utility model provides a roof-type composite paper liquid beverage packaging box, which is surrounded by a piece of integral composite sheet material. On the bottom plane of the box body, the top of the triangular inner folding surface on the two sides of the lower part of the box body, and the top of the inner folding bottom plane at the lower end of the front of the box body are all provided with a lower folding edge seal. The triangular inner folding surfaces on the two sides of the lower part of the box body are folded inward to form a plane, and the inner folding bottom plane at the lower end of the front of the box body is heat-sealed thereon. The lower folding edge seal is heat-sealed on the bottom plane after folding, and the inner folding bottom plane on the back of the box body is heat-sealed on the lower folding edge seal after folding. Since the bottom of this packaging box adopts multi-layer heat-sealing bonding, the anti-leakage effect is far better than that of the existing roof-type packaging box.

Description

Roof Type Composite Paper Liquid Beverage Packaging Box

technical field

The utility model belongs to the technical field of food packaging boxes, in particular to a hermetic roof type composite paper liquid beverage packaging box.

Background technique

In the existing roof-type composite paper liquid beverage packaging box, the bottom folded sheet is folded and heat-sealed in the way of inserting, and it is found through practical application that its leak-proof effect is not good.

Utility model content

In order to prevent the bottom of the beverage box from leaking, the utility model provides a roof type composite paper liquid beverage packaging box, and its implementation is as follows:

The roof-type composite paper liquid beverage packaging box is surrounded by a whole composite sheet material. There are creases pressed on the sheet material. The sheet material is folded into a rectangle along the creases. The top of the box body is formed by two The top surface of the triangular side is folded inward and overlapped with the oblique plane of the top of the box body. There is an upward adhesive surface in the center of the top of the box body, which seals the top of the box body. The top of the whole box body is roof-shaped. There is a box opening in the middle of the front inclined surface, and the bottom of the box body is folded and sealed. On the bottom plane of the box body, the tops of the triangular inwardly folded surfaces on both sides of the lower part of the box body, and the top of the inwardly folded bottom plane at the lower end of the front side of the box body all have One bottom folded edge, the triangular inner folded surface on both sides of the lower part of the box body is folded inward to form a plane, the inner folded bottom plane of the lower front of the box body is heat-sealed on the inner folded surface, and the lower folded edge is heat-sealed on the bottom plane after folding , the inner folded bottom plane on the back of the box body is folded inward and then heat-sealed on the lower folded edge, and the entire bottom surface is a compressed sealing plane.

Since the bottom of this packaging box is bonded by multi-layer heat sealing, the anti-leakage effect is far better than that of the existing roof-type packaging box.

The inner layer of the composite sheet material is a plastic film, the outer layer of the plastic film is an aluminum foil layer, the outer layer of the aluminum foil layer is a base paper, and the outer layer of the base paper is a plastic film layer.

Detailed ways

The roof-type composite paper liquid beverage packaging box shown in Figure 1, Figure 2, Figure 3 and Figure 4 is surrounded by a whole composite sheet material, the sheet material is pressed with a crease 1, and the sheet material is folded along the crease 1 Rectangular, the top of the box body is formed by two triangular side top surfaces 2 on both sides of the upper end of the two box bodies, which are folded inwardly and overlapped with the inclined plane 5 folded inwardly at the top of the box body. Adhesive surface 3, seal the top of the box body, the top of the whole box body is roof-shaped, a box opening 4 is opened in the middle of the front slope of the top, the bottom of the box body is folded and sealed, on the bottom plane of the box body, triangles on both sides of the lower part of the box body The top of the inner folding surface 6 and the inner folding bottom plane 8 top of the box body front lower end all have a lower folding edge sealing 7, and the triangular inner folding surface 6 on both sides of the box body bottom is folded inward to form a plane, and the box body The inwardly folded bottom plane 8 at the lower end of the front is covered on it, and the topmost part is heat-sealed, and the lower folded edge 7 is folded and covered on the bottom plane 8. After the bottom plane 9 is folded inward, the gland is placed on the lower folded edge 7, and the top is also bonded with heat sealing, and the whole bottom surface is bonded with heat to form a sealing plane.

Since the bottom of this packaging box is folded in multiple layers, its anti-leakage effect is better.
