Description

[Detailed explanation of the idea] "Industrial application field" This case relates to a foam jetting container that can be used both vertically and inverted.

``Prior art'' A container body having a body that can be elastically compressed,
A head hanging down from the top wall is fitted into a fitting cylinder having a nozzle and communicating with the base end of the nozzle at the upper part, and an upper end of a liquid outflow pipe which is suspended into the container body is fitted into the fitting cylinder. , an air outflow path is formed between the upper end portion and the fitting cylinder to fit them together, and a porous member with air permeability is fitted in the nozzle or the upper part of the fitting cylinder to compress the body. Therefore, when the pressure inside the container is increased, the liquid inside the container passes through the liquid outflow pipe, and the air above the liquid level in the container passes through the air outflow path and the porous member, and the liquid and the liquid at the time of passing pass through the porous member. The foam is foamed when mixed with air, and the foam is ejected from the nozzle.The negative pressure caused by the reduction of the liquid and air inside the container due to the ejection of foam is caused by the outside air flowing into the container through the nozzle and the porous member. It is known that the problem is resolved by inhalation, and the body of the container is restored to its original state.

"Problems to be solved by the invention" In the conventional foam ejecting containers mentioned above, the porous member for foaming often dries out, and as a result, the adhering liquid dries and the liquid component accumulates within the porous member. This caused clogging, which impaired the foaming function. In addition, when the container is inverted and the body of the container is squeezed, liquid remains in the liquid outflow pipe, and the lower end of the air outflow path is underwater due to the movement of air toward the bottom when the container is inverted, so only liquid remains. However, there were cases where the liquid was spewed out without noticing this.

This proposal aims to eliminate such inconveniences.

"Means for Solving the Problems" A container body 1 having an elastically compressible body 2, and a first top wall 6 at the upper end of a peripheral wall 7 fitted to the mouth of the container body.
A plug-like member 5 having a first cylindrical portion 8 vertically penetrated through the center thereof and having an outside air intake valve 12 on a first top wall portion on the side of the first cylindrical portion; The air-permeable porous member 14 fitted therein and the first
In the lower part of the cylindrical part 8, an air suction path 17 is formed between the upper end of the pipe and the inner surface of the first cylindrical part, and the pipe is suspended and fitted to the bottom of the container body. The outflow pipe 16 and the fourth cylindrical part 23 that hangs down from the center of the second top wall 22 to the rear end of the nozzle hole are connected to the outer surface of the first cylindrical part 8, and a second cylindrical part 23 is provided on the outer surface of the plug-shaped member peripheral wall 7. When the head 20 with the nozzle 21 is fitted with the fifth cylindrical part 24 hanging from the periphery of the top wall 22 so as to be vertically movable, and the container is placed in an inverted state so that the front end of the nozzle faces downward, the nozzle will close due to its own weight. It consists of a swinging member 28 pivotally attached to the front surface of the fifth cylindrical part 24 so as to be swingable forward,
A plug body 25 and a rod portion 26 are respectively suspended from the center and side portions of the second top wall 22 of the head.
5 into the first cylindrical portion 8, and the rod portion 26 into the valve hole of the outside air suction valve, respectively, in a watertight manner and removably.

"Operation" From the state shown in Fig. 1, the head 2 is
0, and remove the stopper 25 and rod part 26 from the first position.
When removed from the cylindrical part 8 and the valve hole of the outside air intake valve and compressed the container body, the liquid passes through the pipe 16,
In addition, the air above the liquid level passes through the air suction passage 17 and further passes through the porous member 14, so that the liquid and air are mixed.
It foams and is ejected from the nozzle 21. When the body is released from compression, outside air enters the container body through the outside air suction valve 12, and the body is restored to its original state. At the time of said use,
When the container is tilted upside down so that the front end of the nozzle faces downward, the swinging member 28 swings toward the front of the nozzle due to its own weight, as shown in FIG. Further, when the head 20 is pushed down against the plug-like member 5, the plug body 25 fits into the first cylindrical portion 8, and the rod portion 26 fits into the valve hole of the outside air intake valve in a watertight manner.

"Example" 1 is a container body having an elastically compressible body 2,
The mouth and neck part 4 is made to protrude upward from the upper end of the torso via the shoulder part 3.

A plug-like member 5 is fitted into the mouth and neck of the container body. This member has a first cylindrical portion 8 which fits a peripheral wall 7 hanging from the periphery of the first top wall 6 into the container neck portion 4 and which penetrates and fixes the center portion of the first top wall in the vertical direction.

Further, a second cylindrical portion 9 having a tapered portion with a small diameter at the upper portion is fixedly penetrated through the first top wall portion on the side of the first cylindrical portion, and is supported by a locking means 10 in the cylindrical portion. The ball valve 11 is loosely fitted. The ball valve and the inner wall surface of the tapered portion form an outside air intake valve 12. Furthermore, a protrusion 13 is attached to the upper end of the peripheral wall 7, and the protrusion 13 is fitted into a vertical groove 27, which will be described later, so as to be vertically movable.

A permeable porous member 14 is fitted into the upper portion of the first cylindrical portion 8 .

Furthermore, an upper end portion of a liquid outflow pipe 16 is fitted into the first cylindrical portion 8 below through the third cylindrical portion 15, and the lower end of the pipe is vertically extended to the bottom of the container body. The third cylindrical part 15 is not necessarily required, and if the third cylindrical part is not provided, a groove is provided between the inner surface of the first cylindrical part and the outer surface of the pipe to form an air suction passage 17 and fit. let In the illustrated example, the third cylindrical part 15 has a horizontal wall 18 on the inner surface slightly below the upper end, and a part of the upper cylindrical wall of the third cylindrical part is cut out 19.
The inside of the lower cylindrical portion of the horizontal wall 18 and the inside of the upper cylindrical portion of the side wall are provided to communicate with each other, and a groove for forming the air suction passage 17 is bored from the outer surface of the lower end of the cutout 19 portion to the lower end of the cylinder.
