Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder spraying device, and more particularly, to easily and reliably storing fine hair powder to improve productivity and quality and to improve powder spraying efficiency by a spray gas. Also, the present invention relates to a powder injection device that facilitates powder replenishment.

[0002]

2. Description of the Related Art Conventionally, there has been a powder ejecting apparatus for hair which attaches powdered fine hair to the hair to give a reduced volume of hair a feeling of volume. You can get the feeling. Examples of the powder injection device include Japanese Patent Publication No. 6-26684, Japanese Utility Model Publication No. 6-12841, Japanese Utility Model Laid-Open No. 6-70850, and Japanese Utility Model Laid-Open No. 7-9448. In each case, a liquefied gas cylinder is stored in a container body in which a powder of fine hair is stored. In this device, a liquefied gas cylinder is ejected from the outside of a container body to inject an injection gas into the inside of the container body, and the powder is sowed by the injection force, and the powder is ejected together with the injection gas. It is to be sprayed outside.

[0003]

The above-mentioned conventional powder injection devices have the following problems. In Japanese Patent Publication No. 6-26684 and Japanese Utility Model Publication No. 6-12841, the liquefied gas (hereinafter referred to as the liquefied gas for injection) which ejects the injection gas targeted for practical use was fluorocarbon (fluorochlorocarbon) gas. . The reason is that Freon is a small volume liquid when stored in liquefied gas,
When ejected as a propellant gas, it becomes a large-volume propellant gas with a large specific gravity, and therefore a large transport capacity, so that the transported object can be efficiently injected, it is a nonflammable gas, and its toxicity to the human body is extremely low. Because of its ideal performance as a jet gas.

[0004] In recent years, stratospheric ozone depletion due to chlorofluorocarbon gas has been taken up as a major global environmental problem, and the liquefied gas for injection has been designated as a specific chlorofluorocarbon by a reduction plan of the Meeting of the Parties to the Montreal Protocol. 1996
Production was completely stopped in the year. For this purpose, the liquefied gas for injection is liquefied propane (LNG) or LNG-dimethyl ether (DM), which was used before the spread of CFCs.
E) It returned to the mixture (hereinafter referred to as LPG etc.).

[0005] Taking the example of Japanese Utility Model Publication No. 6-12841 as an example, in a powder injection apparatus in which the liquefied gas for injection is designed using Freon gas, LPG is used instead of Freon gas as it is.
When such alternatives are used, the liquefied gas for injection is exhausted while a considerable amount of hair remains in the container body. As to the reason, when transporting powder in a gas stream, transport efficiency is generally represented by the ratio of the weight of the powder to be transported / the weight of the gas used for the transport,
The specific gravity of Freon gas and LPG is twice or more that of Freon gas in comparison with LPG even in the state of liquefaction under pressure and in the state of gasification under normal pressure. Therefore, the weight of the liquefied gas for injection that can be filled in the cylinder, that is, the total weight of the injection gas that can be used for the injection and transportation of the powder, is as follows. When the case is compared with the case where LPG or the like is filled, the amount of liquefied chlorofluorocarbon is twice or more. In other words, since the use of the chlorofluorocarbon gas requires twice or more the weight of the transport gas as compared to the LPG or the like, the transport capacity is almost the same multiple. It is considered that the relationship is also substantially the same when the powder is fine hair.

If an liquefied gas for injection having the same weight as Freon gas is attached to a powder injection device by using LPG or the like,
It is necessary to double the volume of the cylinder, and when the size of the container body is not changed, the volume of the fine hair powder must be reduced by the volume of the cylinder. The amount of body is reduced, causing problems in commercialization,
In addition, enlarging the container body in order to maintain the filling amount of the powder increases the size of the product, which is a serious problem in commercialization. Therefore, when the liquefied gas for injection is changed from Freon gas to LPG or the like, it is necessary to devise a method for remarkably improving the transport efficiency itself. As a result of intensive studies, the present inventors have succeeded in improving the transportation efficiency, and the specific inventions are disclosed in Japanese Utility Model Laid-Open Nos. 6-70850 and 7-9.
448.

However, the powder injection device according to the present invention by the present inventors has the following problems.

(1) Among products manufactured in the rainy season when the atmospheric humidity is high, the ejection of fine hair powder from the powder ejection device is sometimes incomplete, and the ejection gas in the gas cylinder is sometimes removed. Even after exhaustion, a considerable amount of powder may remain in the apparatus without being jetted. This is because the fine hair is an artificial fiber material, so it absorbs moisture in proportion to the increase in the humidity in the coexisting atmosphere, and the water content of the fine hair increases. This is because fine hairs can easily become entangled with each other, causing poor injection.

(2) In the operation for storing the fine hair powder in the remaining space in which the gas cylinder is stored in the container body,
Since the powder scatters and adheres to the outside of the container body, this removal operation is required, and the powder is scattered and adheres to the work table, thereby impairing the working environment and deteriorating the quality of the product.

(3) Since the gas cylinder and the fine hair powder coexist in the container main body, a mistake is made between the bottom surface of the gas cylinder and the main body container when the powder is stored in the production of the powder injection device. As a result of the intrusion of the powder, the position of the gas cylinder in the container body moves upward.As a result, the valve of the gas cylinder is slightly pressed and slightly opened, and the liquefied gas continues to leak little by little. Sometimes it became a product.

(4) It is not always easy to reuse the container body and the like as part of effective use of resources. In the above cases (1) and (2), it is conceivable to complete the humidity control of the assembly line and complete the ventilation system. However, the problem that a large amount of equipment cost is required and the problem of (1) is low. Although humidity is desired, (2) has a contradictory problem that a certain high humidity is desired. The present invention solves the above problems (1), (2), and (3), and adopts a method that can easily cope with (4). As an even more important improvement, the above-described powder transport efficiency is improved. It is an object of the present invention to provide a further improved powder injection device.

[0012]

According to the present invention, there is provided a powder injection device comprising: a powder container for storing powder; and a liquefied gas cylinder storing a liquefied gas for ejecting an injection gas from above in the powder container. A container body for accommodating the powder container and the liquefied gas cylinder, and a lid portion detachably mounted on the container body, wherein the liquefied gas ejects the powder to form It is characterized by spouting.

Further, the powder container is not deformed so as not to hinder the powder jetting operation due to collision, friction, and the like between the jet gas and the powder flowing and flowing by the jet gas. It is a material and / or structure having strength.

FIG. 2 is a horizontal sectional view taken along a line, FIG. 2 is an external perspective view of a powder container 10 housed in the powder ejecting apparatus, and FIG. 3 is an external perspective view of the powder ejecting apparatus.

Referring to FIGS. 1 (a) and 1 (b), this powder injection device comprises a powder container 10 for accommodating powder 11 of fine hair.
And a cylindrical gas cylinder 20 to which the nozzle unit 30 is attached, a container body 50 for accommodating the powder container 10 and the gas cylinder 20, an operation lever 61 detachably mounted on the container body 50, and an injection port 68. The provided lid portion 60
And

As shown in the external perspective view of FIG. 2, the powder container 10 is molded so as to be in close contact with the inner wall of the space formed by the container body 50 and the gas cylinder 20 in the horizontal sectional view of FIG. The container has a bottom and an upper edge which is open like an opening 10B. When the lid 60 is mounted on the container body 50, the upper edge of the powder container 10
By making the inner shape of the container close to the wall that has a slightly inner drawing shape, the structure is such that there is no penetration of fine hair between the container body and the powder container, and the powder After assembling the body ejecting apparatus, it is desirable that the powder container is fixed in the powder ejecting apparatus and does not rattle. For this reason, it is self-sustaining, and by the collision, friction, etc. with the propellant gas and the powder that flies and flows by the propellant gas,
If the material and / or the structure has a strength that does not cause deformation that hinders the powder ejection operation, it is not necessary to fix the powder container to the main body container with an adhesive or mechanical means. Since it is enough to insert along the inner wall and the gas cylinder, it is desirable from the viewpoint of manufacture and as a product. The container portion 10A of the powder container 10 can be made, for example, by molding thick paper or a synthetic resin such as polyethylene, polypropylene, polystyrene, and ABS.

However, the present invention is not limited to the above-described structure, and the powder container is temporarily fixed to the container main body 10 by an adhesive or mechanical means even in a flexible powder container having no self-support. Thereby, the same performance and effect can be obtained. The gas cylinder 20 stores a compressed gas G that is injected into the powder 11 stored in the powder container 10 to inject the powder 11 into the outside together with the powder 11 and has a cylinder nozzle 21. It is stored in the powder injection device.

The nozzle unit 30 includes a cap 31 and
An operation lever contact portion 32, a pipe 33, and an injection nozzle 35 provided in an upper space of the powder 11 are attached to the cylinder nozzle 21, and the cylinder nozzle is pressed when the operation lever contact portion 32 is pressed. The opening 21 is opened, and the compressed gas G is injected from the injection nozzle 35 through the cap 31 and the pipe 33.

The container body 50 has a lid 6 as shown in FIG.
0 is detachably covered, and accommodates the powder container 10 and the gas cylinder 20 shown in FIG.

As shown in FIG. 1, the lid 60 is provided with an operation lever 61 and an injection port 68, and the operation lever 61
Operation lever portion 61A abutting on operation lever contact portion 32
And an injection port cover 61B that normally closes the injection port 68, and is rotatably mounted by a pin 61C. By depressing the operation lever 61A, the cap 31 is pushed down via the operation lever contact portion 32, and a valve (not shown) inside the cylinder nozzle 21 is opened, so that the compressed gas G in the gas cylinder 20 is removed from the cap 31. It is injected downward from the flow injection nozzle 35 toward the powder 11 via the pipe 33.

Next, the operation during use of the powder injection device constructed as described above will be described with reference to FIG.

The operation lever section 61 is held by hand holding the powder injection device.
When A is pushed down with a finger, the cap 31 is pushed down through the operation lever-contact portion 32, and a valve (not shown) inside the cylinder nozzle 21 is opened to open the compressed gas G in the gas cylinder 20.
Flows through the cap 31 and the pipe 33 and is jetted downward from the jet nozzle 35 toward the powder 11.

The compressed gas G injected toward the powder 11 is
The powder 11 is raised and the operation lever 61A is pressed, so that the injection port cover 61B is pivoted upward about the pin 61C, and the injection port 68 is in an open state and is raised. The powder 11 is injected outside from the injection port 68 together with the compressed gas G.

Therefore, the above-described powder injection device according to the present invention is provided with the powder 11 stored in the powder container 10 by the compressed gas G.
Can be injected from the injection port 68 to the outside together with the compressed gas G, and since the powder container 10 containing the powder 11 is used, even if the powder 11 is used and completely consumed, the lid 60 is The detached powder container 10 and the gas cylinder 20 are taken out, another powder container 10 in which the powder 11 is stored, and a new gas cylinder 20 are placed in the container body 50 and the lid 60 is covered, so that the container body can be easily placed. Can be reused.

Since the operation of storing the fine hair powder in the powder container 10 can be performed separately from the operation of assembling the powder injection device, the humidity can be easily controlled and the product can be stored. In addition, the storage management is easy.

Although the above embodiment has been described with reference to the embodiment of the powder injection device for injecting the fine hair powder 11, the present invention is not limited to this and can be widely used for other powder injection devices. be able to.

[0028]

The effects of the present invention are as follows.

(1) As described above, the present inventor has proposed, according to the invention of Japanese Utility Model Application Laid-Open No. 7-9448, a powder injection device using LPG or the like having a poor transporting ability as a liquefied gas for injection. Although we succeeded in improving the transportation efficiency, in commercialized products, almost all of the fine hair powder in the powder injection device was ejected, and almost no liquefied gas for injection was used. It was not possible to say that he had enough capacity. For this reason, excessive operation of the operation lever,
When the powder was not loosened at the beginning of use, the device was occasionally incompletely ejected due to slight negative factors such as shaking of the device and loosening. Therefore, a device for further improving transport efficiency has been desired, but surprisingly, the present invention using a powder container has been disclosed in Japanese Utility Model Application Laid-Open No. 7-944.
Application of No. 8 improved the transportation efficiency and achieved the desired results. The reason for this is that when a powder container is not used, such as in experiments with a powder injection device using a transparent container body, part of the jet gas flow from the injection nozzle will It was observed that the gas was circulating in the gap between the gas cylinder along the path, and a part of the injected gas flow did not contribute to the soaring of the powder but was lost. It is considered that the loss has been eliminated.

(2) With respect to products manufactured at a time when the humidity in the atmosphere is high, the problem of insufficient ejection of fine hair powder sometimes occurred. Although the water content of the fine hair increases and decreases in proportion to the humidity in the coexisting atmosphere, the relationship between the water content of the fine hair and the intertwining of the fine hair is subtle. However,
What is necessary is just to store the powder of the fine hair at least in the environment of the humidity of the season other than the rainy season, and according to the present invention,
The storage of the powder in the powder container could be solved by performing the operation separately in a dedicated operation process in which the humidity was controlled, and by performing the operation continuously.

(3) Until now, the powder scattered during the operation of storing the fine hair powder in the container body adheres to the outside of the container body and the work table, and it is necessary to remove the powder. However, according to the present invention, it was possible to solve the problem that the quality of the product was lowered and the working environment was impaired by storing the powder in the powder container in a separate working process.

(4) In the present invention, the problem of the rise of the position of the gas cylinder due to an error in the operation of storing the fine hair powder in the container body, which has been a cause of the leakage of the liquefied gas, has been described in the present invention. The solution was completely solved by separating the powder from the gas cylinder with a powder container.

(5) According to the present invention, if a new powder container and a gas cylinder are prepared, the lid of the used powder injection device is opened, and the used powder container and the gas cylinder are replaced. By doing so, the main body container and the like can be easily reused.

(6) According to the present invention, the work of storing the powder container in the assembling process is extremely simple, and the process balance with other processes can be maintained. Can be easily and continuously performed, so that the overall productivity can be improved.

(7) If the user prepares a new powder container and a gas cylinder, the device can be used permanently by merely refilling when the device is worn.
