Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is directed to a bag in which water-soluble or water-dispersible contents such as powdered soap, seasonings, extracts, or pharmaceuticals are filled into a bag made of a water-soluble packaging material. Concerning a packaging body.

<Prior Art> In order to eliminate the need for measuring powdered soap, seasonings, etc. and to facilitate use, packaging bodies have been known in the past in which the contents of these powders and seasonings are packaged into bags in fixed amounts. This package is used by opening the bag using scissors or the like, pouring the contents into water, hot water, etc. through the opened part, and dissolving or dispersing the contents in the water or hot water.

<Problems to be solved by the invention> However, with conventional packaging, it is troublesome to remove the contents from the bag, and the contents may adhere to the inner surface of the bag. This resulted in a loss of resources. Furthermore, the bag is formed by thermally welding the peripheral edge of the bag using a heat sealing device, but since the heater of the heat sealing device and the bag come into surface contact,
The contents were caught in the heater, resulting in incomplete heat welding, or the trapped contents were burnt, resulting in defective products.

The present invention has been made in consideration of such circumstances, and provides a package that eliminates the need to take out the contents and allows the entire package to be used without any waste.

Means for Solving Problems> The present invention uses a water-soluble packaging material that dissolves when immersed in hot water, etc., and uses ultrasonic waves to reliably form a bag from the water-soluble packaging material. It has been sealed. That is, the present invention is characterized in that the bag to be filled with contents is made of a water-soluble packaging material, and the joining line for sealing the bag is formed by ultrasonic irradiation.

<Examples> The present invention will be specifically described below with reference to illustrative examples.

FIG. 1 is a perspective view of an embodiment of a package according to the present invention. A package 1 is formed by a bag 2 and contents 3 filled and sealed inside the bag 2.

The bag body 2 is formed by overlapping two lumens and forming bonding cotton 4 around the four sides to bond the films to each other. This film is formed by cutting a water-soluble packaging material that dissolves when immersed in water or thirst into a predetermined size, and the water-soluble packaging material may be made of polyvinyl alcohol or starch, which has film-forming properties. The material is selected. The content is water-soluble or water-dispersible powder.

Granular materials etc. are used. The contents 3 are changed as appropriate depending on the purpose of use of the package 10. For example, in the case of eyebrow washing detergent, powdered soap, in the case of seasoning, seasonings, extracts, shaved bonito flakes, kelp, etc., and even for bathing. In some cases, hot bath additives are selected. In addition, in the case of seasoning, the bag body 2 used is one that does not cause any food hygiene problems.

Such a package 1 is used by filling the bag 2 with the amount for one use and putting it into two water stations or the like as it is. As a result, the bag body 2 made of water-soluble packaging material is dissolved in water, hot water, etc.
The contents 3 inside the bag body 2 are dissolved or dispersed. Therefore, since all the contents 3 are used for their intended purpose, there is no waste.

FIG. 2 is a perspective view of an apparatus for forming the joining line 4 of the bag body 2. In this device, an ultrasonic bonding device 10 is used, and the bonding line 4 can be formed by ultrasonic irradiation. The ultrasonic bonding device 10 includes an ultrasonic oscillator 11, a horn 12 attached to the tip surface of the ultrasonic oscillator 11, and a pedestal 13 disposed corresponding to the horn 12. The ultrasonic oscillator 11 has an internal vibrator (
(not shown) is attached to this vibrator, and a horn 12 is attached to this vibrator.
is connected. The horn 12 is formed into a tipped shape, and the amplitude of the vibration from the vibrator is expanded.
Ultrasonic waves are emitted from the tip of 2. A pedestal 13 corresponding to the horn 12 is provided on the opposite side of the film-like water-soluble packaging material A, and is formed entirely into a cone shape that tapers toward the horn 12. is located at the tip of the horn 12 to receive ultrasonic waves from the horn 12. Also, this pedestal 13
is adjusted to move in the axial direction by an adjustment knob 14 attached to the bracket 15, and is kept at a constant distance (0
, 1 to 0.2 mm1. The ultrasonic oscillator 11 to which the pedestal 13 and the horn 12 are attached is configured to reciprocate up and down synchronously and integrally. This is ultrasonic oscillator 11
It can be easily constructed by connecting the bracket 15 of the pedestal 14 with a connecting rod (not shown), and connecting the connecting rod to a driving means (not shown) such as a motor or cylinder. Water-soluble packaging material A1 in which a bonding line is formed by ultrasonic irradiation. A pair of clamp plates 16 are arranged on the supply path to sandwich the packaging material A from both sides.

In general, water-soluble packaging materials A such as polyvinyl alcohol and starch have hygroscopic properties, and shrinkage occurs in the packaging material due to moisture absorption. For this reason, wrinkles are generated in the peripheral portion of the packaging material A, and the degree of polymerization is deteriorated, but the wrinkles can be reduced by clamping and pressing the packaging material A from both sides with the clamp plates 16.

This ensures the formation of a bonding line by ultrasonic irradiation. In this case, packaging material A may not adhere to the clamp plate 16 by coating the surface of the clamp plate 16 with a template agent such as polyester L-based resin such as Teflon (trade name) or Yolikon-based resin. When forming a joining line using such a device, the overlapping packaging material A is held between the clamp plates 16 and the ultrasonic oscillator 11 and the pedestal 13 are moved up or down together. , horn 12
The packaging materials A are bonded to each other by ultrasonic waves. Bonding by ultrasonic irradiation is performed by so-called point contact between the sealing means and the material to be sealed, so that the contents are not caught between the bonded parts, the bonding is complete, and unlike heat sealing, the material to be sealed is Since the welding is not done by melting the materials, but by the friction generated by vibration, there is no weakening of the structure.

In addition, if water-soluble packaging material A wrinkles due to moisture absorption, conventional heat-sealing that joins by surface contact will result in partial non-bonding, so heat-sealing cannot be applied to water-soluble packaging material A. , Ultrasonic bonding is a point contact, and there is no unbonded part. Furthermore, packaging material A undergoes slight vibrations due to ultrasonic irradiation, but the vibrations are most intense at the joining line where the ultrasonic waves are irradiated, so even if the contents adhere to packaging material A due to moisture absorption, the vibrations will not occur. The contents move away from the joining line portion, and the contents do not remain in the joining line portion, allowing complete joining.

3 and 4 are perspective views of another embodiment of the invention. The embodiment of FIG. 3 includes a tray-shaped storage section 5 and a storage section 5.
A bag body 7 is formed by a flange part 6 extending outward from the open end of the bag body 7, and a pair of upper and lower flanges 6 of this bag body 7 are overlapped, and the flange part 6 is irradiated with ultrasonic waves to form a bonded cotton 4. It was formed. In the embodiment shown in FIG. 4, a film-like lid 8 made of a water-soluble packaging material is superposed on a tray-shaped bag 7, and the flange 6 of the bag 7 and the lid 8 are irradiated with ultrasonic waves. It is something that is joined. In these cases as well, water-soluble packaging materials are used for the bag body 7 and the lid body 8. FIG. 5 shows a front view of yet another embodiment. This package 1 is made up of a plurality of bags 9 that are irradiated with ultrasonic waves to form bonding lines 4 on their peripheries, and cutting lines 20 are provided between the bags 9 to cut the bags 9 individually. It is formed. Therefore, cutting line 2
By appropriately selecting 0, a plurality of bags 9 can be used at the same time, and the usage amount can be set according to preference. FIG. 6 also shows a perspective view of yet another embodiment.

A plurality of tray-shaped bags 21, 21a are arranged in series at a flange portion 22, and a film-shaped lid 23 is superposed on the upper surface of the flange portion 22 and bonded by ultrasonic irradiation. Each of the bags 21 and 21a is filled with different types of contents.

For example, if the intended purpose is washing, the bag 21 is filled with soap, and the bag 21a is filled with one or more of a fluorescent agent, a rinsing agent, a bleaching agent, etc. In use, a hole 24 is appropriately opened in the bag 21 filled with powdered soap, and the bag 21 is poured into washing water. As a result, water enters into the bag 21 through the holes 24, so that the water-soluble packaging material of the bag 21 dissolves from both the inside and outside, and dissolves quickly. Therefore, the soap powder in the bag body 21 first dissolves in the washing water, and washing becomes possible. On the other hand, since only the outer surface of the bag body 21a is immersed in the washing water and dissolves slowly, the bag body 21a dissolves at the end of washing. This allows rinsing, bleaching, etc. to be performed continuously after washing. Note that this difference in dissolution rate is due to the thickness of the water-soluble packaging material,
It is also possible to change the material, shape, etc. as appropriate, and 2.
By providing differences in dissolution rates in multiple stages, such as stages, three stages, etc., the work of adding individual contents can be simplified.

Further modifications are possible in the invention.

The shape of the bag may be one triangle, two bales, etc. Further, each individual package or a large number of packages may be further enclosed in an airtight bag, and in this case, long-term storage is possible by sealing a desiccant in the airtight bag.

<Effects of the Invention> As described above, according to the present invention, since the bag is formed from a water-soluble packaging material, it is convenient to use, and all the contents can be effectively used for the intended purpose. Also, since the bag is sealed by ultrasonic irradiation, the water-soluble packaging material can be reliably bonded.
