Description

[Detailed description of the invention] (Industrial application field) This invention, for example, sterilizes surgical gloves while sealed in the bag, and also removes the gloves by peeling off the mating surface of the bag. This paper relates to an adhesive structure that is ideal for sterilization bags, etc.

(Prior Art) FIGS. 5 and 6, shown as conventional examples, show a bag for enclosing surgical gloves.

The bag that encloses the surgical gloves is made by combining two pieces of paper 1 and 2. The inner surface of one piece of paper 1 is coated with a synthetic resin layer 3, and the other piece of paper 2 is coated with a synthetic resin layer 3.
An adhesive layer 4 is provided by applying an adhesive to the entire surface of the adhesive track.

By overlapping the other piece of paper 2 provided with the adhesive layer 4 on one piece of paper 1, a bag for enclosing the above-mentioned surgical gloves can be formed.

When taking out the glove sealed in this bag, both paper pieces 1 and 2 are pulled on both sides to peel off the adhesive layer 4.

(Problem to be Solved by the Present Invention) Therefore, in the bag containing the surgical gloves described above, the adhesive layer 4 must not be easily peeled off, but must also be made so that it can be easily peeled off when the bag is opened. Must be.

However, in the conventional adhesive structure as described above, the adhesive force to both paper pieces 1 and 2 is too strong, so there is a drawback that it is difficult to open the seal.

Furthermore, if the piece of paper is pulled with strong force, paper dust will be generated from the piece of paper, but if surgical gloves are enclosed, it is absolutely necessary to avoid this paper dust from adhering to the glove. However, this conventional adhesive structure has the problem of not being able to prevent the generation of paper dust.

The purpose of this invention is to provide an adhesive structure for bags, etc., in which the adhesive part does not easily peel off under normal conditions, is easy to peel off when the bag is opened, and does not generate paper dust even when it is peeled off. be.

(Means for solving the problem) In order to achieve the above object, this invention has a linear adhesive layer formed by applying adhesive in a linear manner to the mating surfaces of a pair of paper strips, and It is equipped with a planar adhesive layer formed by applying an adhesive, and due to the difference in area between the two adhesive layers,
The present invention is characterized in that the adhesive force of the linear adhesive layer is relatively small.

(Effect of the present invention) Therefore, the portion bonded to the linear adhesive layer is
Since the bonding area is smaller than the portion bonded to the planar adhesive layer, the bonding force thereof is relatively small.

By creating a relative difference in adhesive strength in this way,
When opening the package by pulling on the mating surfaces, the adhesive will peel off from the weak adhesive area.

(Effects of the Present Invention) As described above, since the adhesive is peeled off from the linear adhesive layer, which has a relatively weak adhesive force, it is easy to open the package, and no paper dust or the like is generated even when the package is peeled off.

(Embodiment of this invention) The embodiment of this invention shown in Figs. 1 to 4 is as follows:
A pair of paper pieces 11 and 12 are combined to form a bag,
A synthetic resin layer 13 is formed on the mating surface 11a of one of the pieces of paper 11.

Further, on the mating surface 12a of the other piece of paper 12, a linear adhesive layer 14 and a planar adhesive layer 15 coated with an adhesive are formed on tracks that adhere to the periphery of one piece of paper 11.

In other words, the linear adhesive layer 14 in this embodiment
The adhesive is applied in a mesh pattern along the above-mentioned tracks. Furthermore, a planar adhesive layer 15 is applied on the linear adhesive layer 14 over the entire surface of the track to form a two-layer adhesive layer. It is adhered to the resin layer 13 side.

In this adhesive state, the adhesive strength between the linear adhesive layer 14 and the planar adhesive layer 15, which are adhesives, is the strongest, followed by the adhesive force between the synthetic resin layer 13 and the planar adhesive layer 15, and the linear adhesive layer 14 and the planar adhesive layer 15 have the strongest adhesive force. The adhesive force between the adhesive layer 14 and the paper piece 12 is the weakest. In other words, this linear adhesive layer 14
The adhesive area between the paper strip 12 and the sheet adhesive layer 12 is smaller than that between the planar adhesive layer 15 and the synthetic resin layer 13, so the linear adhesive layer 1
4 and the piece of paper 12 becomes weaker.

In this way, there is a relative difference in the adhesive strength of each adhesive part, so if you pull the pieces of paper 11 and 12 left and right, as shown in FIG. 12 will begin to peel off.

Note that the planar adhesive layer 15 is omitted and both pieces of paper 1 are used.
An experiment was also conducted in which paper pieces 11 and 12 were bonded together using only the linear adhesive layer 14, but in this case both paper pieces 11 and 12 could not be easily peeled off. This is thought to be due to the fact that the adhesive force of the linear adhesive layer 14 to both paper pieces 11 and 12 is equal. When the adhesive forces are equal in this way, not only do the paper pieces 11 and 12 become difficult to peel off, but also paper dust is generated when they are peeled off.

However, if there is a relative difference in adhesive strength as described above, it becomes easier to peel off as described above, and no paper dust is generated.

Regarding the generation of paper dust, the absolute adhesion force to the paper piece 12 is the same whether in the case of only the linear adhesive layer 14 as described above or in the case of this embodiment, so the generation of paper dust will not be affected. It is easy to think that there is no change in the amount of paper dust, but in reality, in this example, almost no paper dust is generated.

Further, in this embodiment, the linear adhesive layer 14 has a net shape, but it does not necessarily have to be a net shape as long as the bonding area is relatively small. However, if this linear adhesive layer 14 is formed into a net shape, there is an advantage that the sealing performance of this adhesive part is improved.
