JPH0811955A - Foam spray container - Google Patents

Abstract

PURPOSE:To make it easy to compress a container even after extended use thereof thereby to prevent foam from being sprayed unevenly by a method wherein the container is turned upside down when it is used and the body of the container is compressed so that foam is sprayed from a nozzle by a spacially constituted foaming mechanism provided in the container. CONSTITUTION:By compressing the body 10 of a container which is turned upside down, liquid in the container is discharged from a liquid outlet through hole 17 into a liquid passage downstream of a foaming layer 9, while the air at the bottom, located above, of the body of the container is compressed and caused to join the liquid in the liquid passage via a pipe 4 so that a mixture of the air and liquid is turned into foam through the layer 9, which foam is sprayed from a nozzle 22. By setting free the compression of the body, the through hole 17 is closed and the air introduced from the nozzle is admitted into the bottom of the container through the pipe so that the air is prevented from passing through the liquid stored therein.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a foam ejection container.

[0002]

2. Description of the Related Art As a foam jetting container, for example, a container body in which a mouth and neck is erected from a squeezable body, and a top of the mouth and neck is fitted to close an opening of the mouth and neck, and a through hole for communicating a pipe is used. And a nozzle cap having a liquid pouring through hole around the through hole and a nozzle cap fitted to the outer circumference of the mouth and neck and provided with a foaming layer such as a net inside. There is.

In these, the container is inverted and the body is squeezed to mix the air supplied through the pipe with the foaming liquid supplied from the liquid pouring through hole, and the net. The bubbles are uniformly bubbled through the nozzles to form bubbles and are ejected from the tip of the nozzle.

[0004]

However, in the conventional container of this kind, when bubbles are continuously ejected, the once compressed body is elastically restored to introduce the outside air, and the body is compressed again. Although bubbles are continuously ejected, not only the outside air introduced at the time of elastic restoration of the body is introduced into the upper end of the inverted body through the pipe, but also from the pouring through hole into the body. be introduced. As a result, the liquid in the barrel is foamed by the air introduced from the pouring hole, and when the body is squeezed again, the bubbles obstruct and it becomes 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 points. Even if it is continuously jetted, the body squeezing does not become heavy and the jetted bubbles do not become non-uniform, and moreover, like the conventional container of this kind. In addition, the present invention proposes an excellent foam ejection container which has a simple structure and can be easily manufactured.

[0008]

[Operation] When the container is used upside down and the body part 10 of the inverted container body is squeezed, the air existing in the upper part of the body part 10 in the upright position moves to the bottom part of the container body located upward due to the upside down, and the pipe Since the end of 4 projects into this air, air is introduced into the movable cylinder 6 from the tip of the pipe (solid line with arrow in FIG. 2). On the other hand, since the elastic wall 8 is pushed down by hydraulic pressure, the seal at the lower edge of the movable cylinder 6 is released, and the liquid in the container body 10 is introduced into the movable cylinder 6 through the through holes 17 for pouring each liquid. (Fig. 2
Double line with arrow). At this time, the tip edge of the movable cylinder 6 is liquid-tightly pressed against the periphery of the nozzle hole on the rear surface of the nozzle cap top wall 21. Next, the introduced air and liquid are used for the foaming layer 9 and the foam stabilizing layer 25.
It is uniformly foamed through and is ejected from the nozzle 22.

Next, when the squeezing of the body 10 is released, the body 10 is elastically restored, and the outside air is introduced from the nozzle 22 accordingly. At this time, the inside of the container body 10 is negatively pressured, and the elastic wall 8 returns to the original state by the elastic restoring force or the like to close the through hole 17 for pouring the liquid, so that there is no introduction of outside air from here. ,
The outside air mainly travels along the outer periphery of the movable cylinder 6 through the gap between the movable cylinder 6 and the nozzle cap top wall 21, and the through hole 24 for ventilation of the movable cylinder 6 is provided.
(Partly through the foaming layer 9 and the foam stabilizing layer 25) and is introduced into the body 10 through the pipe 4 (double line with arrow in FIG. 3). Therefore, air does not pass through the stored liquid.
