Firstly, flattening the surface of the corrugated paper in a rolling or die pressing mode; the glue is coated or the double-sided adhesive tape is adhered on the flat surface, so that the glue and the surface of the corrugated paper can be completely integrated, and the purpose of firm adhesion is achieved.
Description
Technical Field
The utility model relates to a carton or carton, in particular to increase corrugated carton or case bonding area of contact's joint sealing structure.
Background
In the prior art, corrugated cartons or paper boxes are common, and generally, the corrugated cartons or the paper boxes are formed by folding in the prior art, then corresponding articles are loaded into the corrugated cartons or the paper boxes, and then the corrugated cartons or the paper boxes are sealed, wherein the sealing manner is mostly realized by gluing. In the prior art, the middle of the corrugated paper is of a hollow structure, and the surface of the corrugated paper is the whole piece of paper. Although the surface of the paper is the whole paper, the surface of the paper is not flat due to the hollow structure in the middle. The sealing method of the paper box or paper box mostly adopts double-sided adhesive tape for sealing, namely, one sealing surface is adhered with the double-sided adhesive tape or hot melt pressure sensitive adhesive, and when the sealing is needed, the release paper on the surface is torn off and is adhered with the opposite paper box or paper box. Due to the characteristics of corrugated paper, the surface of the corrugated paper is uneven, sometimes, although the corrugated paper looks flat, the user can still feel the uneven surface of the corrugated paper after the user holds the corrugated paper, and a plurality of small bubbles are arranged on a double-sided adhesive (hot melt pressure sensitive adhesive) attached to the box cover or the hot melt pressure sensitive adhesive is directly sprayed (scraped) on the double-sided adhesive or the hot melt pressure sensitive adhesive to cause uneven spraying (scraping). Due to the reasons, the box cover or the box cover can not be completely bonded with the opposite box body when being combined, so that the contact area is small, the bonding strength is low, and the adhesive is not firm.
Disclosure of Invention
The utility model aims to solve among the prior art corrugated box or its surface irregularities of carton and the joint sealing that causes or the not firm problem of joint sealing.
To accomplish the above object, the present invention is realized as follows: a box sealing structure for increasing the bonding contact area of a corrugated paper box or a box is characterized in that the corrugated paper box or the box consists of a box body, a box bottom and a top cover, the box body, the box bottom and the top cover are formed by folding corrugated boards, and a part, needing bonding, of the box body, the box bottom or the top cover is provided with a colloid which is bonded to form the box sealing structure; the viscose surface of the bonding position is provided with an indentation, the surface of the corrugated paper at the indentation position is a flat surface, and the colloid is coated on the flat surface.
The utility model discloses a scheme be in the position of viscose, at first adopt the mode of roll-in or mould pressing to flatten its surface, then carry out the viscose again. The viscose glue comprises a mode of adhering by using double-sided glue and a mode of adhering by using glue and then adhering release paper. Compared with the prior art, the mode has stronger progress, and in the prior art, if the double-sided adhesive tape is directly adhered, the roller wheel is adopted to pass through the adhesive tape slightly after the adhesive tape is adhered. Although the prior art is roll pressed, the purpose of the roll pressing is to adhere one side of the double-sided adhesive tape to the carton, which is to adhere the double-sided adhesive tape firmly to the raised points of the corrugated board (see fig. 1). The utility model firstly adopts the rolling or mould pressing mode to flatten the surface of the corrugated paper; the glue is coated or the double-sided adhesive tape is adhered on the flat surface, so that the glue and the surface of the corrugated paper can be completely integrated, and the purpose of firm adhesion is achieved. Certainly, the utility model does not make requirements on the process sequence, namely, the requirements on flattening and gluing or gluing and flattening are not made; the glue is only required to stick to a flat surface.
The technical scheme is further improved, and the area of the roll mark extends to the edge of the box bottom or the top cover. In order to prevent the gap caused by the indentation when the bonding part is bonded with the opposite box body or cover body or box bottom, the indentation area of the roller needs to be extended to the edge of the box bottom or top cover, thereby avoiding the problems.
The technical proposal is further improved, and the opposite surfaces of the adhesive surfaces are provided with corresponding indentations. In order to make the bonding more firm, not only the initial adhesive surface is provided with the indentation, but also the opposite surface of the adhesive surface is necessarily provided with the indentation; the bonding is most secure because only when two flat surfaces are bonded.
The technical proposal is further improved, the adhesive surface is coated with an adhesive layer, and release paper is arranged on the adhesive layer. And the adhesive surface is adhered with a double-sided adhesive tape. The gluing mode or the bonding mode of the double-sided adhesive tape is not limited, and even more, the adhesive can be directly glued for bonding without a step of sticking release paper.
The technical proposal is further improved, and the release paper is wider than the adhesive layer. The indentation is roller indentation or die indentation; the width of the indentation exceeds the width of the adhesive surface. There are many known ways of forming such a flat indentation, but it is needless to say that the number of the indentation is not limited to one or two of the above-mentioned methods. The main purpose of the limitation of the indentation width is that a transition section is required to be arranged for more compact bonding because of the height difference between the indentation position and the non-indentation position, so that the glue is not easy to generate during bonding.

Detailed Description
Example one
A corrugated paper box or case with firm bonding is composed of a box body, a box bottom and a top cover, wherein the box body, the box bottom and the top cover are formed by folding corrugated boards; the purpose is to provide a transition section to prevent the phenomenon of upwarp caused by the fact that the elasticity is too large and the time is needed for gluing during gluing. The colloid is uniformly coated on the indentation; therefore, all gluing positions can effectively play a role in bonding; the effect of the cross section is shown in figure 2.
Example two
On the basis of the scheme, corresponding indentations are also arranged on the opposite surfaces of the adhesive surfaces; the indentation mode can be a rolling mode or a die pressing mode; the extent of the indentation extends to the edge of the lid.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
