Abstract

PURPOSE:To omit the breaking mechanism of an ampule and a bag and to enhance the safety and reliability of a sprayer by receiving a gas generating substance having an m.p. equal to or lower than room temp. in a container main body and generating the melting thereof after the preparation of the sprayer. CONSTITUTION:A substance melting within a low temp. region equal to or lower than room temp. is used as one or more component of two or more substances constituting the gas generating substance 1 is received or provided in a container main body 2. Further, the temp. of the gas generating substance 1 is lowered so that the substance melting within a low temp. region is melted after a sprayer is prepared. By this method, the gas generating substance 1 is not melted even when it obtains heat energy from the open air through the container main body 2 until the preparation of the sprayer is completed and, when the sprayer is placed at room temp. or placed inside and outside a factory after the preparation is completed, the gas generating substance 1 obtains heat energy from the open air to generate chemical reaction to become a state possible to generate gas.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention is based on the pressure of a propellant and the pressure of a gas generated from a gas generating substance (1), or between the pressure of a propellant and a substance enclosed or installed inside. An aerosol type that uses the pressure of the generated gas or the above pressure, not including the pressure of the propellant, to eject the contents or the above-mentioned enclosed or internal substances to the outside. Regarding sprayers, to explain in more detail, we have developed an aerosol type sprayer that takes advantage of the fact that the temperature after production is higher than the temperature until production is finished due to the lower temperature until production is completed. Regarding the manufacturing method.

[Prior Art] As far as we have investigated, there has been no use of melting in the manufacture of atomizers. However, there are two similar methods for generating gas by causing a chemical reaction after the atomizer is manufactured.

■Put an ampoule into the container body (2) and break it to generate gas.

■A bag containing one drug and a bag containing another drug are placed inside the container body (2), and when the two bags are mixed, the two drugs mix and cause a chemical reaction. This generates gas.

[Old 1 to be Solved by the Invention Although described in the prior art, ■ is when the atomizer is used after being turned upside down or shaken, small pieces of the ampoule formed by breaking it will spray out. I am worried that it will bring about bad luck.

(2) There is a concern that the torn bag may remain inside the container body (2) and block the outlet of the contents.

The present invention provides for a chemical reaction to take place after the manufacture of the atomizer, so that no unnecessary solid objects, such as fragments of ampoules or torn bags, are left in the container body (as described above) during use. An aerosol type sprayer that generates gas by
The purpose is to provide an I-manufacturing method.

[Means for Solving the Problems] In order to achieve the above object, in the aerosol type sprayer of the present invention, two or more gas generating substances (1) contained in or disposed within the container body (2) are used. One or more of the substances that melt during the process from low temperature to normal room temperature is used, or one or more of the substances housed or placed inside the container body (2). First, we used a material that melts during the process from low temperature to room temperature, and the temperature of the material was reduced so that the melting occurred after the atomizer was manufactured.

[Function] In the aerosol type sprayer of the present invention configured as described above, the above-mentioned melting substance is released into the outside air at normal room temperature via the container body (2) etc. until the manufacture of the sprayer is completed. However, if the atomizer is placed in a factory at a normal room temperature even after the manufacture of the atomizer is completed, it will absorb heat energy from the outside air through the container body (2), etc. Obtain and melt.

[Example] An example will be described with reference to the drawings. Figures 1 to 3 and Figure 5 are views of the aerosol type sprayer immediately after manufacture, and no gas is generated. Figure 4 shows the atomizer of Figures 1, 2, and 3. FIG. 3 is a view after some atomization of the contents after being at -membrane chamber temperature for some time after manufacture. 1 to 5 are partial sectional views, and the liquid level display of the contents (content presence display) is omitted. The enclosure container 3 is made of easily stretchable rubber, has a spherical shape, and is not in contact with the container body 2.

(Example 1) A in FIG. 1 was solidified. aqueous solution of citric acid,
When B is a coagulated aqueous solution of baking soda, in FIG. 4, G is a liquid and 4 is a gas.

(Example 2) In FIG. 1, A is a coagulated aqueous solution of enzymes and coenzymes, B is an organic substance, and 4 in FIG. 4 is a gas.

(Example 3) In FIG. 2, C is powdered citric acid, D is ice, and E is powdered baking soda. In FIG. 4, G is a liquid and 4 is a gas.

(Example 4) If F in Fig. 3 is a solidified mixture of anaerobic microorganisms that perform fermentation, their nutrient source, and water, 4 in Fig. 4 is gas.

(Example 5) In Fig. 5, if H is the solidified mixture of the citric acid aqueous solution and the contents, and ■ is the solidified mixture of the baking soda aqueous solution and the contents, then after the aerosol type sprayer is manufactured, Let it come to room temperature for a while.

(Example 6) At 1 atmosphere, if A in FIG. 1 is a hydrogen peroxide solution at -2° C. and B is manganese dioxide, then 4 in FIG. 4 is a gas.

(Example 7) An aqueous solution of citric acid in which C in Fig. 2 is coagulated,
If D is dry ice and E is a coagulated aqueous solution of baking soda, 4 in FIG. 4 is a gas.

To explain in detail (Example 3), which is one of the present embodiments, in a factory at a shell room temperature, before attaching a lid plate etc. to an aerosol type sprayer, that is, when only the container body 2 was in use, citric acid was A sealed container 3 containing baking soda and water at a temperature so low that it will not melt until the end of manufacturing of the sprayer is prepared, and the container 3 is placed into the container body 2. (In this way, even difficult-to-handle powdery objects or slippery water can be easily stored in the specified position, and the enclosure 3 does not allow the above-mentioned enclosed objects to come into direct contact with the outside air. Since the surface area of 3 is generally smaller than the apparent surface area of the object sealed in the enclosure 3, it is easier to maintain a low temperature.>Next, a lid plate is attached to the container body 2, and a propellant (compressed gas) is added to the container body 2. is filled until the pressure inside the container body 2 reaches 10 kg/cm". This pressure lowers the melting point of ice. If the ice is left at room temperature, the water will flow through the container body 2, etc. to the outside air. It continues to gain heat of fusion from the water, which melts and produces water (in this case,
Water is a solvent for citric acid and baking soda, and this water dissolves citric acid and baking soda to create an aqueous solution of citric acid and an aqueous solution of baking soda. This rainwater solution is then mixed. When the pressure inside the container body 2 drops to a certain level by using the sprayer, the mixed aqueous solution causes a chemical reaction and generates gas 4, and the pressure of this gas 4 pushes the enclosure container 3 from the inside and expands it. The internal volume of the enclosure 3 is increased and the pressure within the container body 2 is maintained at a substantially constant pressure.

From the above (Example 1) to (Example 4), (Example 6), and (Example 7)
relates to claim [1] and claim [2], (Example 5)
relates to claim [3].

The shape and material of the enclosure container 3 are diverse.For example, a bag made of soft polyethylene (it is folded to some extent during the construction of the sprayer), an accordion-shaped container made of soft polyethylene, and a piston and cylinder are used. What was there,
etc. are possible.

There are many other ways to store the gas generating substance 1, such as providing an easily stretchable membrane that divides the inside of the container body 2 into an upper side and a lower side, and sealing the gas generating substance 1 in the lower side. The following structure can be considered.

[Effects of the invention] Unlike conventional sprayers, there is no need to provide a recess for breaking ampoules or tearing bags, and the safety of the sprayer is reduced due to fragments of broken ampoules and torn bags. Reliability will not be compromised.
