Abstract

PURPOSE:To permit a plurality of contents separably received in a container to be mixed together in an exact proportion without dirtying the hands at the time of its usage by forming a partition part for dividing the contents into parts in such a manner as to permit its rupture with a weaker force than that of the peripheral edge of the container body. CONSTITUTION:A flexible packaging container consists of a flexible, bag-like container body 1 formed by laying the two sheet materials square in shape and the same in size one upon the other and sealing the peripheral edge 1a are divided into two receiving parts 1c and 1d by a partition part 1b. According to the amount of a mixture to be used at one time, the receiving part 1c is filled with a main epoxy resin agent 2a in a predetermined amount and the receiving part 1d is filled with the main epoxy resin agent 2 and a hardening agent 2b to be mixed with such agent in a predetermined proportion. The partition part 1b is set at a smaller separation strength than the peripheral edge 1a and is easily ruptured when either or both of the receiving parts 1c and 1d are pressed with a finger, etc. In this way the main epoxy resin agent 2a and the hardening agent 2b can be mixed in a sealed state and in an exact proportion in the container body 1.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a flexible adhesive suitable for filling, for example, two-component adhesives, inks, paints, chemicals, etc., especially two-component epoxy resin adhesives, etc. It relates to a packaging container, and more specifically, the inside of the container body is divided into a plurality of accommodating parts by a partition part that can be easily broken, and the contents filled in each accommodating part are separated so that they do not mix with each other, and the partition part is used when in use. This invention relates to a flexible packaging container configured so that the contents in each storage section can be mixed with each other in a sealed state within the container main body by breaking the container.

[Prior Art] For example, in the case of two-component epoxy resin adhesives, the epoxy resin base resin and curing agent are usually filled in separate tubes, and when used, the epoxy resin base resin and curing agent are poured from each tube. The hardening agent and the like are squeezed out, and the epoxy resin base and hardener are mixed in a fixed ratio and applied to the bonding area before the epoxy resin base and hardener react and harden.

[Problem to be solved by the invention]

However, the epoxy resin main ingredient, curing agent, etc. are in the form of a viscous fluid, and although it is easy to use when filled in a tube or the like, it may stain your hands or reduce work efficiency. There was a drawback.

In other words, epoxy resin, curing agent, etc. are squeezed out of a tube or the like into a mixing tray, etc., and mixed. However, there is a risk of getting your hands dirty with the epoxy resin, curing agent, etc. during this mixing process, and it is difficult to adjust the mixing ratio. Although it is necessary to squeeze out the epoxy resin base resin, curing agent, etc., it is difficult to do this on-site, and there are drawbacks such as reduced work efficiency.

Furthermore, errors occur in the ratio of squeezed-out amounts of epoxy resin, curing agent, etc., making it difficult to accurately set the mixing ratio, resulting in disadvantages such as failure to obtain desired adhesive strength.

In addition, since the tube is filled with resin, when the tube is closed with a screw cap after use, the resin near the outlet may leak out, or the end of the tube may be cut and the resin may leak from the cut part. As a result, the outside of the tube becomes wet with resin, giving off a bad odor and making the product unpleasant. Furthermore, there was also the drawback that the resin filled in the tube etc. could not be used until the end.

Therefore, an object of the present invention is to separately fill a two-component epoxy resin adhesive or the like into an epoxy resin base material, a hardening agent, etc., and to mix the epoxy resin base material, hardening agent, etc. at the time of use without getting your hands dirty. It is possible to do this without reducing work efficiency, and the mixing ratio can be set accurately.
To provide a flexible packaging container that can be used until the end without causing discomfort due to leakage of a liquid type epoxy resin adhesive or the like.

[Means to solve the problem]

The present invention is a flexible packaging container in which the interior of a flexible container body with a sealed periphery is partitioned into a plurality of storage parts, and the contents filled in each storage part are stored separately so that they do not mix with each other. The above object has been achieved by providing a flexible packaging container in which a partition section that partitions the accommodating sections is breakable with a force weaker than the periphery of the container body.

(Function) According to the flexible packaging container of the present invention, each accommodating part is filled with a predetermined amount of contents in advance, so there is no fear that the contents will be separated from each other and mixed, and when in use, it corresponds to one of the accommodating parts of the container body. When pressure is applied to the part to be filled, the partition easily breaks, and the filled contents become movable.
If the container body is massaged in this state, the contents can be mixed with each other.

In this mixing operation, the contents are sealed inside the container body, so there is no need to get your hands dirty, unlike when squeezing out the contents filled in each tube etc. into a mixing tray etc. and mixing. , it becomes possible to improve work efficiency.

Also, since the contents can be weighed and filled in advance,
The desired efficacy can be obtained without the risk of inaccurate mixing ratios as would be the case when mixing individual amounts.

In addition, if the filling amount is set to the amount for one use, the packaging container can be disposed of after use, and the contents can be easily disposed of when closing the screw cap after use, such as when filling a tube. There is no risk of leakage to the outside of the tube, etc., causing discomfort, and there is no problem of not being able to use the product until the end.

Example C) Hereinafter, the present invention will be described in detail with reference to the drawings.

(First Embodiment) Fig. 1 is a plan view showing the first embodiment of the flexible packaging container of the present invention, Fig. 2 is an enlarged cross-sectional view taken in the direction of the II-[arrow in Fig. 1, and Fig. 3 shows the state of use.

The inside of the container body 1 is partitioned into two parts, a storage part 1c and a storage part 1d, by a partition part 1b.

Then, a predetermined amount of epoxy resin base material 2a is filled into one storage part 1c according to the usage amount, and a predetermined amount of epoxy resin base material 2a is filled into the other storage part li, which is mixed with the epoxy resin base material 2 at a predetermined mixing ratio. A predetermined amount of agent 2b is filled.

Here, the sorting material constituting the container body 1 is, for example, polypropylene (PP), polyethylene (PE), polybutylene terephthalate (PBT), which can be heat-sealed by heating.
There are also laminated films developed for food products (laminated films made by laminating polyethylene terephthalate or aluminum foil with a heat-adhesive film).

The peripheral edge 1a of the container body 1 and the partition portion 1b are formed by heat sealing. The partition part 1b partitions and separates the storage part IC51d to prevent the epoxy resin base resin 2a and curing agent 2b, which are the filled contents, from mixing with each other, but the peel strength is set to be weaker than that of the peripheral edge 1a. , and can be easily broken when pressure is applied with one or both fingers of the accommodating part IC11d.

In this example, for example, the conditions for thermal fusion (heat sealing),
By changing the heat sealing time, temperature, etc., the peel strength of the partition portion 1b is made weaker than that of the peripheral edge 1a.

In addition, at the end of the peripheral edge 1a on the side of the housing part lc, there is one or more (three in the drawing) cuts 1e cut in a ■ shape.

In the flexible packaging container of this embodiment configured as described above, when pressure is applied with a finger or the like to crush either the accommodating part 1c or the accommodating part 1d, the epoxy resin base material 2a and the curing agent 2b, which are the contents, are released. Pressure is applied to either one of them, and this pressure causes the partition portion 1b to break as shown in FIG. 3, and the separated storage portions 1c and 1d come into communication with each other.

When the entire container body 1 is massaged in this state, the epoxy resin base 2a and the curing agent 2b are mixed in a sealed state inside the container body 1. After sufficiently mixing the epoxy resin base 2a and the curing agent 2b, tear the container body 1 from the cut end 1e, open the container body 1, and squeeze out the mixture of the epoxy resin base 2a and curing agent 2b onto the bonding area from this opening. Apply.

By mixing the epoxy resin main component 2a and the curing agent 2b in a sealed state in the container body 1 in this way, there is no risk of getting your hands dirty, and there is no need to squeeze the mixture into a mixing tray or the like for mixing. , work efficiency can be improved. In addition, since the epoxy resin base material 2a and the curing agent 2b are weighed and filled in advance, there is no need to weigh and mix them on site by eye, as is the case when filling tubes, etc.
The mixing ratio does not become inaccurate, and the adhesive strength as designed can be obtained.

In addition, there is no need to remove the adhesive remaining on the mixing tray etc. after the work is completed, and the remaining adhesive can be removed from the outside of the tube etc. as in the case of filling a tube etc. There is no possibility that the adhesive will leak and cause discomfort, or that adhesive will remain on the adhesive 4' after use and cause loss.
