Description

A kind of hook back box can be avoided cassette bottom four corners dew hole

Technical field

The utility model belongs to packages printing field, and being related to a kind of packing box, especially one kind can be avoided cassette bottom quadrangle The hook back box in place dew hole.

Background technique

In panoramic all kinds of Color box packagings, there is a kind of color box for adapting to automatic assembly line packaging operation to be called Hook back box or self-clinching back box.The bottom structure design for hooking back box is more ingenious, enters after printing, cross cutting and specifically hooks back box Automatic paste box molding machine is finally formed by sizing, fold, pressure viscosity.Only the color box of flattening need to laterally be pushed open when use, Bottom can be achieved with automatic buckling, its advantage is that using when eliminate additional button basic skill or training's sequence, adapted to automatic assembly line packet The demand for pretending industry is greatly saved manually, improves product quality, realize standardized production.Current this hook back box master To be applied in the product that wine box, minaudiere, toothpaste box, medicine box Isoquant are big, production standardization level is high, with industry The use of this cell type of upgrading will be more and more extensive.

But in the specific use process, user generally reacts, and cassette bottom four corners have dew hole, not only influences beauty, Moreover, the product of its inner packing once has breakage, it will trickle down and come out from the hole of bottom, can not only be stained other packagings Box, but also the additional work for increasing cleaning, cause damages to enterprise, are food or pharmaceutical packing by it.

There is hole in cassette bottom four corners, and tracing it to its cause is because butt joint edge needs are die cut by specific angle, so mostly It could dock, mould-cutting precision be required excessively high with the side board edge of respective angles.Once the angle of cross cutting is too small, the hole of exposing is just Greatly, the angle of cross cutting is excessive, and will affect the planarization of bottom surface after carton folds, and therefore, the angle of cross cutting is difficult to control, to institute's mould The required precision of corner cut degree is very stringent.

By the retrieval to patent document, patent document identical with present patent application is not found.

Summary of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art, provide that a kind of structure is simple, facilitates realization, to mould Cut the hook back box that required precision is low, avoids dew hole, smooth beauty.

The utility model solves its technical problem and adopts the following technical solutions to achieve:

A kind of hook back box can be avoided cassette bottom four corners dew hole, including back box ontology is hooked, the bottom for hooking back box ontology Face is made of preceding hook plate, rear hook plate and side plate, is mutually hooked and is filled after preceding hook plate and rear hook plate doubling, the side plate of the two sides is rolled over inwardly Hook plate or the rear top for hooking plate before poststack is pasted onto, it is characterised in that: the preceding hook plate or the rear plate that hooks are by plate body, hook bottom notch And fold notch and constitute, which is the following short trapezium structure of side length on one, it is provided at the following place of plate body and hooks bottom notch, It is provided with the indentation line for being 45 ° with top angle in the right end of plate body, cuts with folding notch in the outer side mold of indentation line, folds and lack The side that mouth intersects with indentation line forms butt joint edge, and the angle between the butt joint edge and plate body long side is 46 ° -47 °.

Moreover, it is minimum value line that the middle line of the intersection point of plate body and side sheet room connection indentation line, which is formed by line, which connects It is maximum value line that the out conductor for connecing indentation line, which is formed by line, and the region between minimum value line and maximum value line is butt joint edge in institute Die station in Measurement Allowance.

The advantages and positive effects of the utility model are as follows:

1. can be avoided the hook back box in cassette bottom four corners dew hole, by the way that the angle between butt joint edge and long side to be designed as 46 ° -47 °, a bevel edge is formed it into, plate or the rear plate that hooks are hooked before making after be overlapped with side plate, the top of bevel edge and side board edge Top be connected to each other, side plate can be covered a part by the lower part of bevel edge, while realizing flattening folds, avoid dew hole The problem of.Efficiently solve the problems, such as unsightly, product trickled down from hole, reduce unnecessary loss for enterprise.

2. can be avoided the hook back box in cassette bottom four corners dew hole, permitted margin of tolerance when cutter cross cutting is increased, Facilitate processing.

3. design is scientific and reasonable for the utility model, have facilitate realizations, it is low to mould-cutting precision requirement, avoid revealing hole, be smooth Beautiful advantage, is a kind of hook back box with higher innovation.

Detailed description of the invention

Fig. 1 is the structural schematic diagram (plane outspread drawing) of the utility model；

The portion the A enlarged drawing (structural schematic diagram of display butt joint edge die station) that Fig. 2 is Fig. 1.

Description of symbols

Plate is hooked before 1-, 2- hooks bottom notch, 3- indentation line, 4- side plate, hook after 5- plate, 6- plate body, 7- middle line, 8- out conductor, 9- butt joint edge, 10- intersection point.

Specific embodiment

The embodiments of the present invention are further described below in conjunction with attached drawing:

A kind of hook back box can be avoided cassette bottom four corners dew hole, including back box ontology is hooked, the bottom for hooking back box ontology Face is made of preceding hook plate 1, rear hook plate 5 and side plate 4, is mutually hooked and is filled after preceding hook plate and rear hook plate doubling, the side plate of the two sides is inside Side hooks plate before being pasted onto after folding or the rear top for hooking plate, innovation are: the preceding hook plate or the rear plate that hooks are by plate body 6, it hooks bottom notch 2 and folds notch and constitute, which is the following short trapezium structure of side length on one, is arranged at the following place of plate body Have and hook bottom notch, the right end of plate body is provided with the indentation line 3 for being 45 ° with top angle, cuts with folding in the outer side mold of indentation line Folded notch folds the side that notch intersects with indentation line and forms butt joint edge 9, and the angle between the butt joint edge and plate body long side is 46°-47°。

It is minimum value line, intersection point connection that the middle line 7 of the intersection point 10 of plate body and side sheet room connection indentation line, which is formed by line, It is maximum value line that the out conductor 8 of indentation line, which is formed by line, and the region between minimum value line and maximum value line is butt joint edge in institute Die station in Measurement Allowance.

By the way that the angle between butt joint edge and long side is designed as 46 ° -47 °, form it into a bevel edge, hooked before making plate or Plate is hooked afterwards after be overlapped with side plate, is connected to each other at the top of the top of bevel edge and side board edge, the lower part of bevel edge can cover side plate A part is covered, while realizing flattening folds, avoids the problem of revealing hole.Efficiently solve unsightly, product is from Kong Chu Unrestrained problem reduces unnecessary loss for enterprise.

Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can Can, therefore, the scope of the utility model is not limited to the embodiment and attached drawing disclosure of that.
