Description

[Detailed explanation of the idea] This case concerns a squeeze former.

Conventionally, there is a squeeze foamer which is made up of an elastically deformable squeeze container equipped with a foaming stopper at the mouth.

This foamer stores the required liquid in a squeeze container, and by squeezing the squeeze container, the liquid is foamed and ejected with a foaming stopper. A porous member is provided in the ejection flow path, and the liquid and air in the container pass through the porous member at the same time, thereby mixing the two and foaming them.

After squirting, by releasing the squeeze, the squeeze container restores itself with its own elasticity and allows outside air to be sucked in.

By the way, this type of foamer is generally designed to eject foam by being inverted, but since the amount of liquid to be mixed and the amount of air are not equal, it is difficult to use it for both normal and inverted operations. In other words, the flow paths for liquid and air are switched between the upright position and the inverted position, which greatly disrupts the balance of flow rates.

This proposal attempts to resolve these difficulties.

The illustrated embodiment will be described below.

The one shown is an elastically deformable squeeze container 1.
A foaming stopper 2 is detachably attached to the mouth 11 of the container, and a pipe 3 is suspended from the foaming stopper into the squeeze container.

The squeeze container 1 is made of synthetic resin, and the body 1
2 is made thin so as to be elastically deformable, and a thread 13 is provided around the outer periphery of the mouth portion 11 at the upper end.

The foaming stopper 2 includes a stopper body 21 that is removably screwed onto the mouth portion 11, and a foaming member 2 that is attached to the stopper body.
2 and a flow path switching valve 23.

The plug body 21 is made of synthetic resin, and has a peripheral wall 21a.
A thread 21b is provided around the inner periphery of the spout 21b, which is removably screwed onto the mouth portion, and an ejection tube 21d is provided to protrude upward from the center of the top wall 21c. A short fitting tube 21e that opens is provided in a protruding manner.

The foam member 22 is made of a net or a nonwoven fabric, and is pasted and installed horizontally at the lower end of the short fitting tube 21e.

The flow path switching valve 23 is of a self-gravity type, and has a bottomed cylinder 23a that is fitted into the short fitting tube 21e at its upper end and hangs down. Concave grooves 23b, 23b are formed across the surface, and through holes 23c, 23c are provided projecting from the top of the concave grooves to penetrate into the bottomed cylinder, and a through hole 23d is bored at a suitable position in the upper half.

Further, a cup-shaped member 23e is fitted to the outer periphery of the lower half of the bottomed cylinder 23a, and the concave grooves 23b, 23
b and a concave groove 23 at the bottom of the cup-shaped member.
A through hole 23f that communicates with b and 23b is bored, and a small fitting tube 23g is vertically provided in communication with the through hole.

Furthermore, the bottomed cylinder 23a has a bottomed sliding tube 2.
3h is installed inside to be able to freely slide up and down, and the bottomed sliding cylinder has a through hole 23d in the upper half of the bottomed cylinder in the middle of the outer circumference when rising, and a hole 23d in the lower half when descending. The liquid flow passages 23 each communicate with the through holes 23c, 23c.
i, and in the liquid circulation groove, liquid holes 23j, 23j penetrating into the bottomed sliding tube are bored, an air hole 23k is bored in the center of the bottom, and inside the bottomed sliding tube. A ball 23l is movably installed inside the air hole 23k so as to close the air hole 23k, and a ball receptacle 23m through which liquid and air can flow is provided at the upper edge of the bottomed sliding cylinder. ball 23
The l is secured.

However, the through hole 23c in the upper half of the bottomed cylinder 23a
and the air hole 23k of the bottomed sliding tube 23h have the same size.

The pipe 3 is made of synthetic resin, and its upper end is fitted into the small fitting tube 23g of the flow path switching valve 23 and hangs down, and its lower end extends to near the bottom of the squeeze container 1.

With the above configuration, the required liquid is stored in the squeeze container 1, and in the upright position shown in FIG.
When the body 12 of the squeeze container 1 is squeezed, the body is elastically deformed, the liquid and air inside are pressurized, and the liquid enters the flow path switching valve 23 through the pipe 3 and the through hole 23f. In the flow path switching valve, since the bottomed sliding tube 23h is in a descending state, the liquid passes through the grooves 23b, 23b, through holes 23c, 23c, and then flows through the liquid distribution groove 23i of the bottomed sliding tube 23h. The liquid flows into the bottomed sliding cylinder 23h through the liquid passage holes 23j, 23j, passes through the upper part of the bottomed cylinder 23a, and is sent to the foaming member 22. Further, air enters the bottomed cylinder 23a through the through hole 23d in the upper half of the bottomed cylinder 23a, and is similarly sent to the foam member 22. The ratio between the amount of liquid and the amount of air at this time is best determined by the sizes of the liquid holes 23j, 23j of the bottomed sliding cylinder 23h and the through hole 23d in the upper half of the bottomed cylinder 23a.

The liquid and air sent to the foaming member 22 are mixed in the foaming member 22, become foam, and are ejected from the ejection tube 21d.

Next, in the inverted position shown in FIG. 2, the bottomed sliding tube 23
The first h is determined by the own weight and the weight of the ball 23l.
As shown in the figure, the ball 23l slides upward and the air hole 23k
Move away from it and open it.

When the body 12 of the squeeze container 1 is compressed and elastically deformed in this state, the liquid in the squeeze container passes through the through hole 23d in the upper half of the bottomed cylinder 23a, and the liquid flow groove 23i in the bottomed sliding cylinder 23h. and liquid hole 23
j, 23j and enters the bottomed sliding tube 23h,
It is sent to the developing member 22. In addition, the air in the squeeze container is transferred to the pipe 3, the through hole 23f, the groove 23b,
23b and through holes 23c, 23c, enters the lower half of the bottomed cylinder 23a, passes through the air hole 23k at the bottom of the bottomed sliding tube 23h, passes through the bottomed sliding tube, and is sent to the foam member 22. It will be done. At this time, the ratio between the liquid amount and the air amount is determined by the liquid hole 23j of the bottomed sliding tube 23h,
It is best determined by the size of the air hole 23j and the air hole 23k.

The liquid and air sent to the foaming member 22 are mixed in the foaming member to form foam, which is ejected from the ejection tube 21d, as in the case of the upright posture.

After squirting bubbles, release the squeeze container 1.
The elastic deformation of the squeeze container restores it to its original shape due to its own elasticity and draws in outside air.

According to the present invention, the foaming plug 2 is provided with a flow path switching valve 23 that moves by itself depending on the forward and reverse posture, and this valve is allowed to freely switch between the liquid and air flow paths, so that it can be used for both normal and inverted positions. Moreover, the ratio of liquid to air can be optimized in each case, and good foam can be obtained.
