Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for packaging a two-part reactive adhesive.

[0002]

2. Description of the Related Art Conventionally, as a packaging method of a two-part reactive adhesive, a main agent and a curing agent have been respectively placed in a metal tube, a plastic or glass bottle, and a metal can. Material, or in the form of clay, the main agent and the curing agent,
It is the same as making a stick shape, then winding it in a roll shape with transparent vinyl, and further making a stick shape, but the main agent, curing agent,
Some are left inside with one of them inside, and the other is wrapped around the outside like a Kintaro candy.

[0003]

These have the following disadvantages. (1) Except for the double bar, each time you use it,
It is troublesome because the curing agent must be measured. In particular, when the mixing ratio is, for example, 10: 1 by weight or 6: 1 by volume, it is very difficult to measure accurately with human intuition, but if the mixing ratio is incorrect, it will not cure. And did not adhere. In general, this type of adhesive has a relatively small specific gravity, so its volume is large compared to its weight. For example, even if the weight is 1 gram, it is too much to be used for repair or filling work in general homes, car repair shops, etc. However, when only a small amount is required, an accurate electronic balance or balance is required for accurate weighing. (II) Bar-shaped objects should be cut to the same length with the edges aligned, and double bar-shaped objects can be simply cut or torn off with a cutter or the like.
There is a restriction that the palm must be degreased and washed, and if you knead it by hand, your hands will get dirty. (III) Mixing is basically performed on a degreased and clean plate in any of the packaging forms, but the used plate is difficult to be removed or cleaned because the remaining adhesive solidifies during the operation. Most of the time, it was troublesome and abandoned, so most of the time you had to prepare a troublesome plate every time you used the adhesive. (IV) Objects other than those containing tubes are not completely shielded from air and light, so if they are stored for a long period of time, they should be stored in a cool and dark place. Although it is made of metal, it is very thin, so it is easy to open a hole. If a hole is made at one end, it will protrude more and more and become useless. (V) It is difficult to return the tubed material once it has been squeezed out to the tube again, so that it often goes out too much and is wasted. (VI) Unless the cap is put on after use, trash in bottles and cans is easy to enter, and those in tubes are protruding. The present invention provides a packaging method for a two-part reactive adhesive, which solves the above-mentioned drawbacks, has good storage stability, is easy to use, and can easily and surely obtain a mixing ratio that can maximize the performance of the adhesive. It is intended to be.

[0004]

The present invention has been made as follows in order to solve the above-mentioned drawbacks. (I) The base material 4 on the substrate 2 made of a material which does not react with the adhesive
And a depression for the curing agent 5 are provided independently. (II) The main agent 4 and the curing agent 5 are weighed and filled into each of the depressions so as to obtain the most efficient mixing ratio, and a thin sheet 3 is laminated thereon and sealed. (III) In the package 1b made of a soft film, the main agent 4 accurately measured so as to have the most efficient mixing ratio with each other.
And the curing agent 5 were placed next to each other, sealed with a soft adhesive portion 7 therebetween.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIGS. 1, 2, 4, and 5 show one of the representative embodiments of the present invention. As shown in FIG. 1, separate depressions for the main agent 4 and the curing agent 5 are provided side by side on the substrate 2, and the main agent 4 and the curing agent 5 are accurately measured in these depressions so as to obtain the most efficient mixing ratio with each other. After that, the sheets are filled, and a thin sheet 3 is bonded and sealed. Here, the substrate 2 has such a rigidity that the substrate 2 can stand on its own without being bent, even if the adhesive is mixed with the stick 6 while holding the substrate 2 with one hand. Further, if the substrate 2 and the sheet 3 are made of a thin plastic sheet or a vapor-deposited aluminum sheet which is in contact with each other so that light does not pass therethrough, it is effective to improve the preservability.

In the embodiment shown in FIG. 3, a main agent 4 and a hardener 5 are arranged adjacent to each other in a package 1b made of a soft film, and only a hatched portion 7 serving as a partition is softly adhered to the main agent 4. And the surrounding area surrounding the curing agent 5 are sealed as usual adhesive.

The embodiment shown in FIG. 6 is an example of a case where the product is actually commercialized. In the package body 1 shown in FIG. 1, several kinds of the main agent 4 such as 10 g, 3 g, 1 g and 0.3 g are selected from the top.
The amount of the curing agent 5 corresponding to each is also packed side by side.

In the embodiment shown in FIG. 7, the main agent 4 is a package containing only the main agent 4 and the curing agent 5 is a package containing only the curing agent 5.

[0007] As in the embodiment of the present invention, the amount of
If g, 3 g, 1 g, and 0.3 g are set, packages of the curing agent 5 in the amounts corresponding to the amounts of the main agent 4 are prepared. At that time, the same code is printed on the sheet 3 of the package body 1 of the corresponding main agent 4 and curing agent 5, respectively, or according to each amount, the sheet 3 is, for example, blue for 10 g, red for 3 g, and 1 g for It is effective if green and 0.3 g are colored and classified into white and the like, and the sealing sheet 3 of the package 1 of the corresponding amount of the curing agent 5 is classified as the same color.

FIGS. 8, 9 and 10 are modifications of the embodiment of FIG. 3, but the partitioning portions 7b, 7c and 7d of the main agent 4 and the hardening agent 5 indicated by oblique lines are softly adhered, and the periphery surrounding the whole is shown. The parts are the same as in the embodiment of FIG.

[0010] In the embodiment shown in Figs.

As shown in the above, it is effective to prepare several kinds of materials whose contents are changed without changing the mixing ratio of the main agent 4 and the curing agent 5.

It is effective to attach sandpaper or cloth to the outside of the sheet 3 because it is not necessary to separately prepare sandpaper when surface roughening is required.

A soft adhesive may be applied to the outside of the sheet 3 even after drying by mixing mulled sand.

The present invention is configured as described above, and its usage is as follows. In FIG. 4, the sealing sheet 3 of the package 1 is peeled off, and as shown in FIG. 5, all the curing agent 5 is scraped out with the stick 6 and mixed with the main agent 4. After that, it may be applied or filled according to the usage of each adhesive.

When the mixing ratio of the main agent 4 and the curing agent 5 is small, that is, when the amounts of the main agent 4 and the curing agent 5 do not greatly differ from each other,
When the cross-sectional shape is as shown in FIG. 2, the adhesive overflows from the depression during mixing, and at this time, the bottom of one of the depressions is
In the embodiment shown in FIG. 12, if the volume adjusting depression 8 is pushed with the stick 6 during mixing, the volume adjusting depression 8 protrudes outward as shown in FIG. If the size of the capacity adjusting recess 8 is adjusted according to the mixing ratio, the adhesive will not overflow during mixing.

When the adhesive in the embodiment shown in FIGS. 3, 8, 9 and 10 is used, pressing the portion containing the main agent 4 or the hardening agent 5 with a finger causes the soft adhesive portions 7, 7b and 7c. ,
Only 7d peels off. After that, since the package 1b is a soft material such as vinyl, if the package 1b is rubbed for an appropriate time, the main agent 4 and the curing agent 5 are mixed. When the cuts 9 are sufficiently mixed, the package 1b is pressed down by pressing both sides of the cut 9 and the package body 1b is pressed, whereby the usable adhesive is pushed out. After that, it is sufficient to apply or fill the adhesive surface according to the usage of each adhesive.

[0016]

Since the present invention is configured as described above, the following effects can be obtained. (I) It is easy to use because there is no need to pay attention to the mixing ratio, and since an accurate mixing ratio is always obtained, it is difficult to obtain an accurate mixing ratio only by human intuition. It is particularly effective for mold adhesives. (II) In the package of the type shown in FIG. 1, if the sheet 3 is peeled off, the substrate 2 becomes a mixing plate as it is.
In the package of the type (1), the mixing is completed in the package only by breaking the soft adhesive portion 7, and in any case, it is not necessary to prepare a mixing plate. (III) In any of the packages represented in FIGS. 1 and 3, since they are completely shielded from the outside air until they are opened, they are not easily oxidized, and if a packaging material that does not transmit light is used, adhesion of ultraviolet rays or the like is used. Since the light which deteriorates the agent does not enter, the storage stability is high. (IV)

[0007]

As shown in the above, the required amount of adhesive can be immediately prepared by appropriately combining the packs of each size.
It's easy even if you want to increase a little. (V) Since it is divided into small parts, only a small hole is opened like a tube or the like, so that the whole is not damaged. (VI) It is convenient to carry because it is subdivided and has high preservability, and there is no need to prepare a separate mixing plate. (VII) The adhesive is not made excessively by mistake. (VIII) In the case of a type of adhesive requiring surface roughening

[0011]

As described above, if a sandpaper-like material is pasted on the sheet 3, it is not necessary to separately prepare the sandpaper.
