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 fitting cylinder having a nozzle and communicating with the base end of the nozzle at the upper part is fitted with a head hanging down from the top wall, and inside the fitting cylinder, an upper end of a liquid outflow pipe is suspended into the container body. , 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" The above-mentioned conventional foam jetting container was designed to jet foam while the container body was in an upright position. Therefore, for example, when the container is inverted, the air inside the container moves toward the bottom of the container body, the lower end of the liquid outflow pipe opens into the air, and the base end of the air outflow path opens into the liquid. It should be possible to foam the body by squeezing the body of the container in the same way as when the container is erected, but in reality, when the container is erected, the liquid remaining in the pipe is pushed out before the air, so the container When the body of the container was squeezed while the body was held upside down, only liquid was initially ejected, and bubbles were ejected only after the liquid in the pipe had disappeared.

The present invention eliminates the above-mentioned drawbacks and is designed so that only bubbles are ejected even when the container is in an upright position or in an inverted position.

"Means for Solving the Problem" A container body 1 having a body 2 that can be elastically compressed, a peripheral wall 7 fitted to the mouth of the container body, and a center portion of the first top wall 6 at the upper end of the peripheral wall are vertically moved. A first cylindrical portion 8 penetrating in the direction
A plug-like member 5 has an air-permeable porous member 9 fitted in the upper part thereof, and has an outside air intake valve 12 on the first top wall portion on the side of the first cylinder part, and The upper part of the third cylindrical part 13 is fitted into the inner surface of the third cylindrical part by forming an air suction passage 21 between the upper outer surface of the third cylindrical part and the inner surface of the first cylindrical part. The lower end surface of the peripheral wall 16 hanging down from the periphery of the flange-shaped second top wall 15 is closed with the bottom wall 17, and the bottom wall portion that is misaligned with respect to the lower part of the third cylinder is opened 18, and the pipe 19 is inserted from the opening. A fourth cylindrical part 27 that hangs down from the third top wall 26 in communication with the nozzle 25 is fitted to the outer surface of the first cylindrical part 8 so as to be vertically movable. It consists of a head 24 with a nozzle 25, and a first protrusion 28 that closes the upper end opening of the first cylindrical part when the head is pressed down is vertically provided from the center of the third top wall 26, and A second protrusion 29 that closes the valve hole is provided vertically from the side of the third top wall 26.

"Operation" Pull up the head 24 from the state shown,
When the body 2 of the container body 1 is squeezed in an upright state, the pipe 19, the storage chamber 20,
The liquid passes through the third cylindrical part 13, and the air intake passage 21
The air above the liquid level in the container is mixed and foamed through the porous member 9 and passes through the nozzle 2.
It erupts from 5. Furthermore, when the body is released, outside air enters the container body mainly through the outside air intake valve 12, and the body is elastically restored.

Next, when the container body is turned upside down, the liquid inside the container moves to the top side of the container body, and the base end of the air suction passage 21 opens into the liquid, and the air inside the container moves to the bottom side of the container body, and the air inside the container moves to the bottom side of the container body. The bottom end opens into the air,
The liquid in the pipe 19 flows into the storage chamber 20 due to the misalignment between the bottom wall opening 18 at the upper end of the pipe and the lower end of the third cylindrical part 13.
Air enters the pipe. When the body of the container is squeezed from this state, liquid from the air suction passage 21 and air from the pipe 19 pass through the porous member 9, and foam is ejected from the nozzle 25 due to mixing during the passage.

"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. The member has a first cylindrical portion 8 which fits a peripheral wall 7 hanging down from the peripheral edge 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, A permeable porous member 9 is fitted into the upper part of the first cylindrical portion. In addition, a second cylindrical portion 10 having an upwardly projecting portion tapered to a small diameter is fixed to the first top wall portion on the side of the first cylindrical portion, and a second cylindrical portion 10 is fixedly inserted into the second cylindrical portion from the inner diameter of the second cylindrical portion. The ball valve 11 with a small outer diameter is movable up and down, and is fitted with the inner surface of the tapered part to prevent the ball valve from falling off by a plurality of locking parts 11a provided in the lower part of the second cylindrical part. An outside air intake valve 12 is provided with a ball valve.

A third cylinder part 13 is fitted into the lower part of the first cylinder part 8, and an auxiliary member 14 is attached thereto. The auxiliary member closes, with a bottom wall 17, the lower end surface of a peripheral wall 16 that hangs down from the periphery of an outwardly flange-shaped second top wall 15 attached to the upper part of the third cylinder, and is displaced relative to the lower part of the third cylinder. An opening 18 is formed in the bottom wall portion, and a pipe 19 is installed vertically into the container body through the opening. The bottom wall 17, the peripheral wall 16, and the second top wall 15 form a storage chamber 20. Further, a groove 21 is vertically provided on the outer surface of the third cylindrical portion fitted into the first cylindrical portion 8, and a notch 22 is formed in the cylindrical portion above the groove.
A horizontal wall 23 is provided on the inner surface of the cylindrical portion, and the liquid passing upward through the third cylindrical portion is blocked by the horizontal wall 23 and passes through the notch 22.
The air that moves upward through the groove and passes upward into the groove mixes with the liquid in the notch and passes through the upper end of the third cylinder, and the thus mixed liquid and air mix. Further, a porous member 9 is provided for further mixing by passing through the porous member 9.

24 is a head with nozzles 25, in which a fourth cylindrical part 27 hanging down from the third top wall 26 is fitted to the outer surface of the first cylindrical part 8 so as to be able to move up and down, and the upper part of the fourth cylindrical part and the nozzles 25 are connected to each other. The end is provided so as to communicate with the end when the head is pulled up.

"Effect of the invention" The present invention has the pipe 19 suspended from the storage chamber 20 into the container body as in the previously described configuration, and the opening 18 at the upper end of the pipe.
Since the position of the lower part of the third cylindrical part 13 is shifted, the liquid in the pipe 19 will enter the storage chamber 20 when the container is inverted. This method is also convenient because it allows bubbles to be ejected instead of the liquid being ejected as is in the conventional method. In addition, since the outside air suction valve 12 is provided, when the container is upright, outside air is sucked into the container through the outside air suction valve, so that the elastic recovery of the container body is quickly performed, and when the container is upright, the outside air is sucked into the container. Since the outside air intake valve is closed, no liquid can leak through the valve.
