Abstract
The utility model relates to packaging containers made of paper composite materials using box making machines, in particular to an anti-seepage packaging container. The utility model has the shortcomings in the prior art that paper on edges in inner layer sealing positions of the packaging container tends to expose inside the packaging container so that food can filter down into a composite layer, and meanwhile, the ingredients of the composite layer of the packaging container can spread into packaged food, thereby negatively impacting the quality of the food. The utility model aims to design an anti-seepage packaging container, which adopts the structure that a diaphragm seal (3) is hot-stuck to the edge longitudinal seal adhesion edges (2) in the inner layer sealing positions of a paper tube (1), and edges at the inner sealing positions of a U-shaped section diaphragm seal (3) enclosing the paper tube (1) form a sealing surface (5). The utility model is dedicated to solving the anti-seepage problem of the packaging container during continuous production. In addition to the benefits of improving the forming effect of the packaging container and enhancing the stability of production quality, the utility model is high in finished product ratio and low in manufacturing cost, and therefore is particularly suitable for large-scale industrialized production.
Description
One, described field
The utility model relates to the packing container that paper composite material is made into by box machine, especially refers to the packing container of food that is used for the long-term aseptic preservation of can needs made by paper composite material, i.e. the packing container of antiseep.
Two, background technology
The inner layer material of the packing container of paper composite material making at present is the plastics of good barrier property, seepage can not take place.But at its overlap joint involution place, the paper that is in packing container internal layer involution place arris can be exposed in the packing container, and the food of dress can destroy the structure of packing container from the penetrating into the composite bed of the paper internal layer arris section that reveals in the packing container; Simultaneously the composition in the packing container composite bed also can be diffused into from the internal layer arris section that exposes the food of packing and go, and influences the quality and the shelf-life of food.In order to address these problems, method at present commonly used has two kinds: a kind of is that the arris outside face that will be in packing container internal layer involution place machines away half of thickness, and then with remaining half doubling, the plastics of packing internal layer good barrier property can be with paper package in the inboard, and the isolated good plastics of property of packing internal layer can be exposed at the involution place of packing container internal layer; The paper of energy actv. elimination packing container internal layer involution place arris is exposed to the influence that is caused in the packing container like this.Another kind method is that the isolated good section of property of failure-free subsides one deck is " one " font plastic film bar on the arris surface at packing container internal layer involution place, cuts off the interpenetrative passage of paper of interior food of packing container and packing container internal layer involution place arris; The paper of so also can actv. eliminating packing container internal layer involution place arris is exposed to the influence that is caused in the packing container.But above method complex process, equipment investment are big, in producing continuously poor operability, the forming effect that influences packing container, quality stability is poor, the finished product rate is low and the high deficiency of productive costs.
Three, summary of the invention
The purpose of this utility model is the problem that exists in the above-mentioned background technology, designs a kind of packing container of antiseep, adopts brand new, simple and practical method, has realized the antiseep of packing container in producing continuously easily.Improved simultaneously packing container forming effect, the stability that has improved the quality of production, technology is simple, equipment investment is little, finished product rate height and productive costs are low, is particularly suitable for large-scale industrial production.
Solution of the present utility model is as follows:
A kind of packing container of antiseep is made up of paper tube and diaphragm seal, it is characterized in that: the vertical envelope of the arris at paper tube internal layer involution place adhesion side place heat bonding diaphragm seal forms sealing surface at the section diaphragm seal arris that encases paper tube internal layer involution place that takes the shape of the letter U.
Advantage of the present utility model and effect are as follows:
1, the packing container of this antiseep, technology is simple in producing continuously, has realized the antiseep of packing container easily.
2, the packing container of this antiseep, easy to operate, stable and reliable operation, product quality stability is good.
3, the packing container of this antiseep does not destroy the structure of packaging material, and the forming effect of packing container is good.
4, the packing container of this antiseep, the annex that increases on former system cartridge device is few, and equipment investment is little, and productive costs is low.
5, the packing container of this antiseep can not send out at vertical envelope place to have prevented the generation of seepage cocksure, finished product rate height.
6, the packing container of this antiseep can satisfy high-revolving needs, and high efficiency is fit to large-scale industrial production.
Four, description of drawings
Accompanying drawing 1 of the present utility model is that the scheme drawing that packaging material seals into paper tube also is the semi-finished scheme drawing of antiseep packing container; Fig. 2 is the section-drawing at the vertical envelope place of paper tube, also is that A-A among Fig. 1 is to view; Fig. 3 is the scheme drawing behind the stickup diaphragm seal on the packaging material.
Number in the figure is described as follows: 1-paper tube, the vertical envelope of 2-adhesion side, 3-diaphragm seal, 4-packaging material, 5-sealing surface.
Five, specific embodiment
Following adjoint is described in further detail: as Fig. 1, Fig. 2, shown in Figure 3, packaging material 4 is a kind of composite materials of being made up of paper, barrier material and plastics, and its inside and outside surface is cohesible plastics.Diaphragm seal 3 is plastic sheetings of a kind of good barrier property, its internal layer and skin can with plastic bonding.As Fig. 2, shown in Figure 3, packaging material 4 involutions are being become before the paper tube 1, part with diaphragm seal 3 Widths is bonded on the vertical envelope adhesion side 2 of packaging material 4 earlier, with another part of diaphragm seal 3 Widths that vertical envelope adhesion side 2 parcels of packaging material 4 are bonding again, diaphragm seal 3 is just with the whole environmental sealings of paper of the vertical envelope adhesion side 2 of packaging material 4 like this.As shown in Figure 1, with existing box machine packaging material 4 folded, glued are become paper tube 1 again, the cross section of paper tube 1 can be Any shape (as rectangle, circle and a polygon etc.), and paper tube 1 is made into packing container by known processing technology with paper tube 1 again by sealing surface 5 adhesive seal.
By the packing container of above method production, because at sealing surface 5 places of paper tube 1, whole sealed film 3 environmental sealings of the paper of the vertical envelope adhesion side 2 of packaging material 4 have cut off food and the vertical interpenetrative passage of adhesion side 2 paper that seals in the packing container.Eliminated the influence that vertical envelope adhesion side 2 paper in the packing container are exposed in the packing container to be caused with regard to failure-free like this.Thereby realized the antiseep of packing container.
Claims (1)
1, a kind of packing container of antiseep, form by paper tube (1) and diaphragm seal (3), it is characterized in that: the arris at paper tube (1) internal layer involution place vertical envelope adhesion side (2) is located heat bonding diaphragm seal (3), forms sealing surface (5) at section diaphragm seal (3) arris that encases paper tube (1) internal layer involution place that takes the shape of the letter U.
