[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-viscosity paste or cream for toothpaste, cosmetics, etc., from general containers that are not pressurized, such as manufacturing tanks, product storage tanks, transportation tanks, and transportation containers. The present invention relates to a pressurized discharge method of contents, which can discharge contents made of substances easily and in a short time.

2. Description of the Related Art
When manufacturing highly viscous paste or creamy substances such as toothpaste, cosmetics, etc., the contents, that is, the above paste, from general containers that are not pressurized specifications such as manufacturing tanks, product storage tanks, transport tanks, and transport containers. Alternatively, in order to discharge the creamy substance, it is general to provide a suction pump at the bottom of these containers and suck the contents with this pump.

However, in this method, the discharge time of the contents is regulated by the ability of the suction pump and
There is a problem that it takes a long time to discharge, and the content remains on the wall surface of the container to lower the recovery rate. Therefore, it is desired to develop a content discharge method that does not have the above problems.

The present invention has been made in view of the above circumstances, and it is possible to easily and easily prepare a high-viscosity paste-like or cream-like substance as a content from a general container which is not a pressure specification for manufacturing, transportation, etc. It is an object of the present invention to provide a pressurized discharge method for contents that can be discharged in time.

[0005]

In order to achieve the above object, the present invention is applied to a non-pressurized container in which a highly viscous paste-like or cream-like content is housed and whose internal pressure is normal pressure. Compressed air in the container is 0.1 to 1.9 kg / cm ²
Provided is a method for pressurizing and discharging a content, wherein the content is supplied under pressure and the content is pressurized and discharged from a content discharge port of the container.

According to the pressure discharge method of the present invention, high-viscosity paste-like or cream-like contents can be easily and shortly produced from general containers which are not pressurized specifications, such as manufacturing tanks, product storage tanks, transport tanks, and transport containers. Since it can be discharged in time and there is no need to use a pressurized container, it is safe and economically advantageous.

Here, if the inside of the container is pressurized to a pressure of 2.0 kg / cm ² or more, it is necessary to use a container with a pressurizing specification, so the container is expensive and economically disadvantageous, and for safety reasons. Will cause problems, but 0.1-1.9 kg / cm
^With the pressure of ² , it is not necessary to make the container a pressure specification.

Further, in particular, according to the method of the present invention, the discharging time of the contents made of the high-viscosity paste-like or cream-like substance is suppressed to about 2/3 to 1/2 times that in the unpressurized state. In addition, it is possible to reduce the residual adhesion of the contents to the wall surface of the container as compared with the case where the general container is sucked and discharged without pressure, and it is possible to greatly contribute to the improvement of the recovery rate and the reduction of the loss.

Therefore, the method of the present invention can be effectively used for manufacturing toothpaste, cosmetics and the like.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail below.

When the method of the present invention is carried out, a general container not having a pressure specification as described above is used, and a pressurized air supply mechanism capable of adjusting the original pressure and a mechanism for releasing the internal pressure of the container are used. It is preferable to use a device as shown in FIG. 1 in which an internal pressure monitoring and adjusting mechanism is installed.

That is, the apparatus shown in FIG. 1 is provided with a pressurized air supply port 2 at the upper end portion of a general container 1 which is not of a pressure specification, and the pressurized air supply port 2 has a blower at one end as a pressurized air supply mechanism. A pressurized air supply device 3 such as the above is connected, and one end of a pressurized air supply pipe 6 in which an air regulator 4 and an air source valve or a pressure control valve 5 are interposed is connected to the upper end of the container 1. An air outlet 7 is provided, and a pressurized air outlet pipe 9 having a pressure release valve 8 as a pressure release mechanism is connected to the air outlet 7. Further, a sensor portion of a pressure sensor 10 capable of outputting externally is inserted into the container 1 as an internal pressure monitoring and adjusting mechanism, and the internal pressure of the container 1 measured by the pressure sensor 10 can be monitored by a pressure management device 11. In addition, in the pressure management device 11, the air source valve or the pressure control valve 5 and the pressure release valve 8
The opening and closing of can be controlled. Container 1
A contents discharge port 12 is provided in the lower part of the, and a contents discharge pipe 13 is connected to the contents discharge port 12. In addition,
A suction pump 14 is interposed in the discharge pipe 13.

In this case, the container 1 is a container that does not have a pressurizing specification, and more specifically, a manufacturing tank, a product storage tank,
Examples include a transport tank and a transport container.

In the above apparatus, the pressurized air supply port 2 is provided in the container 1 which has such a non-pressurized specification and the internal pressure is normal pressure (atmospheric pressure).
While the pressurized air is supplied from the pressure sensor 10, the pressure inside the container is measured in real time by the pressure sensor 10 and monitored and monitored by the pressure management device 11. The command from this causes the air regulator 4 and the air source valve or the pressure control valve 5 to operate. At the same time as the supply of pressurized air is accelerated or suppressed by opening / closing, the pressure release valve 8 is opened / closed to discharge or suppress pressurized air, and the container internal pressure is controlled within a certain range.

Here, the internal pressure of the container is 0.1 to 1.
9 kg / cm ^2, preferably in the range which in particular pressurized 0.2~0.4kg / cm ² pressure, pressurization 0.1 kg / c
If it is less than m ² , the content is not discharged satisfactorily and 1.9 kg
Above / cm ² , expensive pressure vessels must be used. Therefore, if it exceeds 1.9 kg / cm ² ,
The pressure release valve 8 is opened to control the pressure state to 1.9 kg / cm ² or less.

As the pressure management device 11, a management computer, a programmable logic controller or the like can be preferably used.

In the present invention, the contents of the container are discharged from the discharge port 12 in the above-mentioned internal pressure control state. In this case, the contents discharge pipe 13 connected to the contents discharge port 12 is generally used. The contents can be sucked and discharged through the suction pump 14 used in the above.

The method of the present invention is useful when a paste-like or cream-like substance having a high viscosity, specifically, a substance having a viscosity of 30 to 1300 poise / 25 ° C. is used as a content, for example, toothpaste, It can be effectively used when manufacturing cosmetics and the like.

The present invention will be specifically described below with reference to Examples and Comparative Examples, but the present invention is not limited to the following Examples.

[Examples and Comparative Examples] Toothpastes having the viscosities shown in Tables 1 and 2 were filled as contents into a non-pressurized container of the apparatus shown in FIG. 1, and the pressurizing pressure shown in Table 1 was adjusted to the internal pressure. The contents were discharged while controlling. The suction pump was not operated. Discharge rate at that time (kg / mi
n. ), Decrease in viscosity (in the case of contents of 500 to 700 poise / 25 ° C,%), and recovery rates are shown in Tables 1 and 2.

[0022]

[Table 2]

From the results of Tables 1 and 2, it was confirmed that according to the method of the present invention, the highly viscous contents can be discharged from the container of non-pressurized specification under pressure in a simple and short time.

Further, as can be seen from the above results, the discharge rate is rapidly increased by 2 to 2.5 times by applying a pressure of 0.2 to 0.4 kg / cm ² as compared with the normal pressure state. However, even if the pressurization pressure is increased thereafter, the rate of increase in the discharge rate will level off, and the higher the viscosity, the higher the effect of increasing the discharge rate by pressurization, but the greater the decrease in the viscosity of the contents due to pressurization. In terms of product quality, 0.2-0.4kg / c
It has been found that a pressurizing pressure of m ² is considered to be the most desirable range.
