Description

A kind of sealing structure of flat beverage package box

Technical field

The utility model relates to a kind of beverage package box, particularly a kind of sealing structure that adopts the flat beverage package box that composite packing paper makes.

Background technology

Flat beverage package box (being commonly called as brick shape box) is widely used in the packing of beverage, and is generous because of good looking appearance, drinks conveniently, liked by the customer.It generally is to adopt composite packing paper to make, and thin layer, paperboard layer etc. are arranged, and plays oxygen barrier, every light with prevent the beverage osmosis, thereby can prolong the freshness date of guaranteeing the quality of beverage.Its bottom seal is to adopt the thermal current injection method, makes the bonding place film melts, pushes molding bonded again.Usually the bottom seal structure of flat beverage package box generally comprises the two relative base angle face bag bottom surfaces relative with two, and two base angle faces expose, and promptly in bottom, bag bottom surface, thickness is big owing to turn back in the bag bottom surface, and is exposed at outward on the bag bottom surface, influences the attractive in appearance of product.In addition, vertically the outer overlap joint otch of involution is positioned on the medium position in box body front, causes the pattern of positive printing generally to be difficult to align, and is unfavorable for the popularization and the sale of product.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and sealing structure that a kind of improved flat beverage package box is provided, improves its sealing property and packing effect, guarantees the product design of packaged beverage.

The purpose of this utility model can realize by following technical measures: this packing box is made with composite packing paper, the bottom of box body comprises the two relative base angle face bag bottom surfaces relative with two, two base angle faces are concordant with the side cut of two bag bottom surfaces, roll in the Zhe angle of base angle face, position, face limit, base angle outside the Zhe angle is provided with adhesion side, one bag bottom surface and position, the cooresponding limit of face adhesion side, base angle are made as flanging, flanging is oppositely turnover outwards, and with base angle face adhesion side, another bag corresponding sides position, bottom surface butt joint is bonding, the butt joint adhesion side is folded in the bag end, the base angle face, the side cut mouth of bag bottom surface is all in the box body outside, the base angle face, all contact surfaces of bag bottom surface all bond mutually, bonding becomes an integral body at the bottom of the box, and the outer overlap joint otch of the vertical involution of box body is positioned on the corner positions of box body.The composite packing paper of producing this packing box earlier carries out impression by the edging line, and it is bonding press impression Zhe combined pressure envelope again, and it is adhesion-molded to adopt existing equipment to heat press seal.

The utility model is reasonable in design, and is simple in structure, and base angle face, bag position, limit, bottom surface Butt sealing are effective, and the mouth of cutting edge has avoided beverage from mouthful seepage of cutting edge all in the box body outside, thereby guarantees the quality of flat beverage products, the freshness date of guaranteeing the quality that prolongs beverage; The base angle face is located at the box body the inside, and outside the bottom surface is bonding to wrap by wrapping, and can simplify bonding pressing module, and can guarantee specious; Vertically the outer overlap joint otch of involution is positioned on the corner positions of box body, and the pattern continuity of assurance printing and attractive in appearance helps the popularization and the sale of product.
