Description

[Detailed explanation of the idea]

The present invention relates to a container for storing a hair treatment, and more particularly to a container that is adapted to suck up and dispense a fixed amount using a pump device. BACKGROUND ART Containers for liquid cosmetics such as shampoos and conditioners are already in use, in which the contents can be taken out in fixed amounts using a pump. Pump devices for liquid cosmetic containers of this kind generally push shampoo, rinse, etc. that have been sucked up into the pump case in advance from the discharge port by pushing in a discharge pipe equipped with an operating section, and when the operating section returns, it is pumped out again. The liquid is sucked up into the pump case. By the way, recently, there has been an increasing demand for high viscosity cosmetics such as hair treatments to be able to be taken out in desired amounts using such pump devices, but in the case of hair treatments, they are in the form of emulsion-type creams. The viscosity is higher than that of shampoos and conditioners, and it is difficult to achieve a uniform viscosity, and the fluidity is poor. It is not possible to reliably suck up and discharge. In other words, even high-viscosity shampoos and conditioners have a viscosity of about 2,000 to 3,000 centipoise, but hair treatments are based on oily ingredients such as higher alcohols and surfactants (mainly cationic surfactants). Creamy and viscous emulsion of oily ingredients with surfactants.
It has a higher viscosity of 20,000 to 30,000 centipoise than shampoos and conditioners, and it is difficult to maintain a uniform viscosity and has poor fluidity, so if you use containers with pumps used for liquid cosmetics such as shampoos and conditioners, However, it is not possible to stably take out the desired amount of hair treatment stored in the container until the remaining amount becomes low. Therefore, we tried placing a hard plate on top of the hair treatment in the container to make it easier to suck it up with the pump, but the hair treatment had a high viscosity and poor fluidity, making it difficult to form a flat top surface. Therefore, there was a problem in that a partial gap was created at the interface between the hard plate and the hair treatment, making it impossible to stably suck up and discharge the hair treatment, making it impossible to obtain satisfactory results. The present invention was developed with the aim of solving these problems, and its structure is such that a suction tube is inserted into the main body of the container that houses the hair treatment, and the suction tube is connected to the upper end of the suction tube. The container body was a hair treatment container in which the hair treatment was sucked up by a pump device and discharged from an outlet on the discharge side of the pump device, and an insertion hole through which the suction tube penetrated was provided in the container body. A soft board made of a synthetic resin board or a foamed synthetic resin board with a hardness of 50° to 85° as determined by a JIS A hardness tester is inserted, and this soft board is used for hair treatment. Place it on the top surface to cover the top surface of the hair treatment, and also use this soft board.
It is characterized by being movable in the vertical direction with respect to the suction tube and the container body, so that it descends as the upper surface level of the hair treatment falls.By using such a soft plate, the hair It has become possible to obtain a good ejection condition, which was previously unobtainable, without creating a gap between the treatment and the treatment. In the present invention, by placing the above-mentioned soft plate on the top surface of the hair treatment,
The reason why the hair treatment can now be taken out stably is considered to be due to the following reasons. First of all, to explain in detail the reason why it was not possible to take out the hair treatment stably when applying the pump-equipped container used for conventional liquid cosmetics such as shampoo and conditioner to the hair treatment, the hair treatment has a high viscosity. , it is difficult to maintain a uniform viscosity, and it has poor fluidity, so the hair treatment placed in the container lacks uniformity in viscosity distribution, causing parts of the container with particularly high viscosity to be separated from areas with lower viscosity. occurs. In such a situation, if you try to push the operation part of the pump to take out the hair treatment,
It is absorbed from the areas with low viscosity, and the height (thickness of the hair treatment layer) in that area becomes lower.
However, because the hair treatment has a high viscosity and poor fluidity, the hair treatment from other areas does not flow sufficiently into the area where the height has decreased due to wicking, resulting in an uneven top surface of the hair treatment and a high A low point occurs. When this process is repeated, the height of the low points becomes lower and lower until the pump starts sucking in air, making it impossible to take out the hair treatment in constant amounts.
Furthermore, if this continues, the hair treatment becomes difficult to take out even though a considerable amount of hair treatment remains in the container. However, when a soft plate is placed on top of the hair treatment as in the present invention, even if the pump sucks up the low viscosity part when taking out the hair treatment, the height of the soft plate becomes lower due to the above suction. It forces the hair treatment from other areas onto the hair treatment area, which evens out the top surface of the hair treatment and averages out the height, and the pump does not suck in air, ensuring a consistent flow until the hair treatment runs out. It can be taken out in small quantities. It is also possible to place a hard plate on top of the hair treatment instead of the above-mentioned soft plate, but a hard PVC resin plate that is hard and not very flexible is not compatible with the hair treatment. Moreover, the flowability of the hair treatment is poor, and partial voids are created at the contact surface with the hair treatment, making it impossible to suck up and discharge as stably as in the case of the soft plate. In the present invention, as the above-mentioned soft board, a solid synthetic resin board such as a soft vinyl chloride resin board or a foamed synthetic resin board such as a foamed styrene resin board is used. In the case of solid synthetic resin plates, JIS A
Those with a hardness of 50° to 85° when measured with a hardness meter are used. In the case of foamed synthetic resin boards, the hardness cannot be measured accurately using the hardness tester mentioned above, but a material with a similar hardness based on touch, that is, a material with a low degree of foaming and which is relatively hard for foamed materials, is used. . In other words, as a soft plate, even if it is called soft, if it is too soft and does not have self-shape retention, the hair treatment will have a high viscosity and poor fluidity, so it will not be effective to equalize the top surface of the hair treatment in the container. If the material is too hard, it will be difficult to use, and if it is too hard, a phenomenon similar to that of hard vinyl chloride resin plates will occur, resulting in partial voids at the contact surface with the hair treatment, making it difficult to absorb and discharge the hair treatment stably. Therefore, as a soft board, a material having the above-mentioned hardness is suitable from the viewpoint of having self-shape retention and being able to be deformed by human power (hand). Hereinafter, the configuration of the present invention will be explained based on an illustrated embodiment. In FIGS. 1 to 3, 1 is a container body with an open top, and 2 is a screw into the top opening of the container body 1. The main body cover 2 is screwed onto the main body cover 2 through a cylindrical portion 3, and a cylindrical portion 4 projecting upward is integrally formed in the center of the main body cover 2. Reference numeral 5 denotes a pump cap that is attached by screws 6 so as to cover the upper end opening of the cylindrical portion 4. 7
is a cylindrical pump case, and a flange 8 formed at the upper end of the pump case 7 is fixed to the back surface of the pump cap 5. Also,
A suction pipe 9 is inserted and fixed to the suction side, which is the lower end of the pump case 7, and the lower end of the suction pipe 9 faces the bottom of the container body 1. 10
is a discharge pipe bent into an L-shape, and the lower end of its vertical portion 11 passes through the pump cap 5 and is slidably inserted into the pump case 7. A lower ball valve 12 is inserted into the pump case 7 so as to close the suction side thereof.The lower ball valve 12 has its upper end attached to the lower end side of the discharge pipe 10, and is connected to the pump case 7. The spring 13 supported by the spring receiver 21 having an outlet 22 provides a stop valve structure that prevents flow from flowing from the pump case 7 to the suction pipe 9 side. On the other hand, on the upper side of the spring receiver 21,
A stop valve type upper ball valve 2 that closes the outlet 22 to prevent air, etc. from flowing in from the outlet 15 side.
3 has been inserted. A hair treatment is stored in this container. In the drawings, Fig. 2 shows the state before taking out the hair treatment, and Fig. 3 shows the state after taking out a certain amount of the hair treatment. The pump case 7 is filled with the hair treatment that has been sucked up, and from this state the discharge pipe 1
0 by pressing the flat operation part 14 formed on the top surface of the
When the discharge pipe 10 is pushed downward until it reaches the state shown in FIG. 3, the hair treatment inside the pump case 7 is blocked by the lower ball valve 12 and cannot be moved downward. The upper ball valve 23 is pushed open, the liquid is forced upward through the vertical portion 11 of the discharge pipe 10, and can be discharged and taken out from the discharge port 15 of the discharge pipe 10. Further, when the discharge pipe 10 is released from being pushed in, the discharge pipe 10 returns upward due to the force of the spring 13, but at this time, the upper ball valve 23 is moved to the outlet 22 by the air pressure on the discharge pipe 11 side. At the same time, the lower ball valve 12 opens and the hair treatment in the container body 1 is sucked up again into the pump case 7 via the suction pipe 9. As mentioned above, the pump case 7, the ball valve 12,
In a container equipped with a discharge mechanism using a pump device 16 consisting of a pump 22, a discharge pipe 10, etc., the present invention has an insertion hole 17 in the center of the container main body 1 through which the suction pipe 9 passes; A soft plate 18 whose outer edge shape is equal to or slightly smaller than the inner shape of the container body is inserted and placed on the upper surface of the hair treatment, and the upper surface of the hair treatment is covered with this soft plate 18. As such a soft board 18, as described above, a solid synthetic resin board or a foamed synthetic resin board, such as a soft vinyl chloride resin board, having a hardness of 50° to 85° according to a JIS A hardness meter is used. . According to experiments by the creators of the present invention, it is possible to use such a soft plate 18.

[Table] As shown in Table 1, with the container of the present invention, it was possible to take out the hair treatment until the remaining amount was 50g (in other words, it was possible to take out 950g of hair treatment), but compared to the conventional container. In the example container, 333g of hair treatment remained in the container without being able to be removed. In addition, even with the container of the present invention, in order for 50 g of hair treatment to remain in the container without being able to be taken out as described above, a gap must be provided between the lower end of the suction tube 9 and the bottom inner surface of the container body 1. The amount of hair treatment that cannot be taken out can be reduced by, for example, reducing the diameter of the container. In addition, with the container of the present invention, it was possible to take out a nearly constant amount of hair treatment every time until it became almost impossible to take out, but with conventional containers, a nearly constant amount of hair treatment could be taken out immediately after the start of taking out the hair treatment. It was possible to take out the food, but from a relatively early stage, the amount taken out for each extraction began to vary, especially when the amount taken out was 500g.
After that time, the amount taken out began to vary widely. The difference in the dispensing effect between the container of the present invention and the conventional container as described above is that the hair treatment has a high viscosity and is difficult to achieve a uniform viscosity, resulting in a lack of uniformity in viscosity distribution and poor fluidity. Therefore, in conventional containers, the top surface of the hair treatment is not uniform as the pump device removes it.
Whereas the pump device sucks air with a large amount of hair treatment left inside the container body, in the container of the present invention, a foamed styrene resin board as the soft plate 18 is placed on the top surface of the hair treatment. This is thought to be because the top surface of the hair treatment was kept uniform for a long time even as the removal by the pump device progressed. Table 2 below shows the results of examining the stability of taking out the hair treatment from the container of the present invention and a comparative container in which a hard vinyl chloride resin plate was inserted into the container body. The test is performed on viscosity as above.
Using 25,000 centipoise hair treatment, 1 kg each is filled into the container body, and in the container of the present invention, a foamed styrene resin plate similar to that described above is inserted as a soft plate into the container body and placed on the top surface of the hair treatment. In the container of the control example, a hard vinyl chloride resin plate having the same shape and size as the above-mentioned expanded styrene resin plate was inserted into the container body and placed on the top surface of the hair treatment. 10 containers of the present invention and 10 containers of the control example were each tested, and Table 2 shows the containers from which the hair treatment could be taken out until the remaining amount of hair treatment in the container body was 80 g or less. The number is shown as the number of stable retrieval containers.

[Table] As is clear from the results shown in Table 2, all of the containers of the present invention that were tested were able to take out the hair treatment in a stable manner, but the containers of the control example There were some things that lacked stability. This is thought to be due to the fact that in the container of the control example, a partial void was generated at the contact surface between the hard vinyl chloride resin plate and the hair treatment. FIGS. 4 and 5 show other embodiments of the present invention in which the soft plate 18 is prevented from tilting. In FIG. In the case where continuous cylindrical collars 20 are integrally formed, FIG.
0 is shown with an insertion hole 17 in its inner circumference. The present invention has the above-mentioned configuration, and according to the present invention, a soft plate is inserted into the container body and placed on the upper surface of the hair treatment, and this soft plate is lowered to the level of the upper surface of the hair treatment. By lowering the amount of hair treatment with the pump, it is possible to obtain good dispensing results that could not be achieved with liquid cosmetic containers equipped with conventional pumps, and it is now possible to always take out a certain amount of hair treatment reliably. It is something that
