Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a foam ejection container.

[0002]

[Prior art] [Problems to be solved by the device]

 Examples of the foam jetting container include a container body in which the mouth and neck is erected from a squeezable body, and a top hole of the mouth and neck that is fitted to the top of the mouth and neck to close the top and neck of the mouth, and a through hole for pipe communication and a periphery of the through hole. It is known that it is composed of an inner plug having a liquid pouring through hole, and a nozzle cap fitted to the outer circumference of the mouth and neck and having a porous layer such as a mesh provided inside thereof.

[0003] These are such that the air supplied through the pipe and the foaming liquid supplied from the liquid pouring hole are mixed in the cap by inverting the container and squeezing the body. It is configured such that it passes through the porous layer, foams uniformly, becomes a foam, and is ejected from the nozzle tip.

However, in the conventional container of this type, when bubbles are continuously ejected, the once compressed body is elastically restored to introduce outside air, and the body is again compressed to continuously eject bubbles. However, the outside air introduced when the body elastically restores is introduced not only into the upper end of the inverted body via the pipe, but also into the body through the pouring through hole. As a result, air introduced from the pouring through hole causes the liquid in the body to foam, and when the body is squeezed again, the foam interferes and it is difficult to pour the liquid from the pouring hole. (Squeezing becomes heavy), and the bubbles to be ejected are also non-uniform because the gas-liquid mixing ratio is significantly different.

The present invention has been made in view of the above-mentioned points. Even when continuously ejected, the body squeeze does not become heavy, the ejected bubbles do not become uneven, and moreover, like the conventional container of this kind. In addition, we propose an excellent bubble ejection container that has a simple structure and can be formed by a simple modification of an existing container.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the container of the present invention is fitted with the container body 2 in which the mouth and neck 10 is erected from the squeezable body 8 and the upper end of the mouth and neck 10 to close the opening of the upper end of the mouth and neck 10. A through hole 13 for pipe communication is formed in the center of the top plate portion 11, and a through hole 14 for liquid pouring is formed around the through hole, and the through hole 13 for pipe communication. The upper end is connected to the inner plug 3 to fix the upper end to the inner plug 3, and the lower end is hung from the lower part of the body 8 of the container body, and the lower part of the peripheral wall 16 is fitted around the outer periphery of the mouth / neck part 10. In addition, the nozzle cap 5 in which the nozzle 18 is erected from the center of the top wall 17 extending from the upper end of the peripheral wall 16 and the upper surface of the inner plug top plate 11 outside the through hole 14 for liquid pouring are capped. And a valve plate 22 that closes the through hole 14 so that the through hole 14 can be opened and closed. And, and, and the support cylinder member 6 formed by drilled holes 21 in the cylindrical wall 19, and composed of the porous layer 7 for horizontally provided in the member 6 upper.

[0007]

[Action]

 When the body part 8 of the inverted container body is squeezed, the air existing in the upper part of the body part 8 in the upright position moves to the bottom part of the container body located above due to the upside down, and the end of the pipe 4 projects into this air. Air is introduced into the nozzle cap 5 from the tip of the pipe, and liquid is introduced into the cap from the liquid pouring through hole 14 by opening the valve plate 22. At this time, the introduced air and liquid are uniformly foamed through the porous layer 7 and ejected from the nozzle 18.

Next, when the squeezing of the body portion 8 is released, the body portion 8 is elastically restored, and accordingly, the outside air is introduced from the nozzle 18. At this time, the inside of the container body 8 has a negative pressure, and the valve plate 22 closes the liquid pouring through hole 14, so that there is no introduction of outside air from here, and the outside air is mainly passed through the through hole 21 of the cylinder wall. It is introduced into the body 8 through the pipe 4 (partly via the porous layer 7). Therefore, the liquid in the body portion 8 does not foam, and the squeeze does not become heavy or the bubbles do not become non-uniform when the body portion is pressed again.
