[Means for Solving the Problems]

 The present invention has been proposed in order to achieve the above-mentioned object, and provides a container body, a twist cap including an outer cap and an inner cap, in a screwed or connected state with excellent airtightness. The foaming operation and the external air intake operation are performed by separate independent mechanisms, and the air supply required for foaming is supplied to at least one communicating vertical groove formed on the inner peripheral wall surface of the pipe joint. It has a technical feature in that it is configured by a vent hole formed between the pipe and the outer wall of the pipe inserted therein.

That is, according to the present invention, in the foamed liquid squeezing container in which the twist cap composed of the outer cap 1 and the inner cap 2 is screwed to the container body deformable by the external pressure, the inner cap 2 is located at the lower side. Is threadedly engaged with the neck portion 41 of the container main body via a threaded portion 23a formed on the inner surface of the peripheral wall extending to the center, and the fluid circulation mechanisms 24, 51 are formed at approximately the central portion and two locations adjacent to the central portion. The central portion of the fluid flow mechanism 24 is closed at the upper end 25 and has an opening 26 for discharging a foamy liquid on a side surface located slightly below the upper end, and communicates with the opening below the opening 26. Is formed as a tubular portion in which a pipe joint insertion portion 21 is formed, and the other fluid circulation mechanism 51 is located inside the container at a position eccentric from the central portion via the wall surface 27 of the tubular portion. Release of gas from It is provided as a check valve mechanism 51 having a ball 52 configured to be vertically movable inside so as to prevent discharge and to control intake from the outside of the container, and a tip opening is provided above the pipe joint insertion portion. A tubular ring 32 having a mesh-shaped screen 31 arranged on the entire surface is inserted, and a mesh-shaped screen 33 is arranged below the entire surface of the tip opening, and at least one ring is formed on the inner peripheral surface below. The pipe joint 3 in which the vertical groove 34 is formed is inserted in contact with the inner surface of the tubular portion, and further, the pipe 35 which is circumscribed in the vertical groove and extends to the bottom of the container is attached to the inner surface of the pipe joint, and The cap 1 has an opening 11 at its tip, and an inner wall of the opening has a ring-shaped partition wall 12 which is fitted with the front end of the tubular portion of the inner cap. Lap It is foamed liquid squeeze container, wherein provided that it is screwed rotatably more within the engagement portion 23b formed in the peripheral wall outer periphery extending upwardly a predetermined angle.

An embodiment of a twist cap screwed into a foam liquid squeezing container of the present invention is shown in a longitudinal sectional view in FIG. 1, the right half of the center line of the drawing is a state in which the outer cap is opened. The left half shows the state in which the twist cap is closed. In FIG. 1, 1 is an outer cap, 2 is an inner cap, and these two caps are combined to form a twist cap. Reference numeral 3 denotes a pipe joint which is formed of a tubular body having a narrow opening 36 in the central portion which is inserted into the tubular portion of the inner cap. The inner cap is screwed with the neck portion 41 of the container body through a screwing portion 23 formed on the inner surface of the peripheral wall extending downward, and the tip 25 is closed at the substantially central portion 24 of the inner cap. A plurality of openings 26 are radially formed in a portion located slightly below, and a screen 31 made of a synthetic fiber or a metal mesh is opened in a tubular portion 21 having a hole communicating with the openings below the opening. A tubular ring 32 arranged over the entire surface of the tubular portion is inserted, and the tubular ring 32 is brought into contact with the jaw portion 28 formed in the internal combustion portion of the tubular portion and locked in a close contact state. Further, below that, a pipe joint 3 made of a tubular body having a screen 33 similar to that described above arranged on the entire opening is inserted. The screen may be attached to the tubular ring in a welded state, but if it is simply placed in contact with the tubular ring, it will be fixed by the pressing force of the pipe joint and will be sufficient to achieve its purpose. is there.

Around the inner wall of the pipe joint, at least one continuous vertical groove 34 is engraved up to a jaw 37 with which the pipe abuts, and a pipe 35 for liquid supply is inserted outside the vertical groove 34. The pipe extends to the bottom of the container body. Further, a check valve mechanism 51 is formed in a portion located between the tubular portion and the peripheral wall 22 via the wall surface 27 of the tubular portion. The check valve mechanism has a ball 52 made of stainless steel inside, and the ball is arranged so as to be movable up and down. When the ball is pushed up from inside by the fluid, the upper opening 54 is closed, and when the pressure is released. The ball moves downward by its own weight and is supported by the support piece 53, and a gap 55 is formed between the support piece 53 and the ball 52. (See Figure 2 which shows the bottom view of the check valve mechanism)

Next, a mechanism in which the liquid contained in the container is foamed by using the twist cap will be described. The outer cap 1 has an opening at the tip thereof, and an annular partition for downwardly fitting the distal end 25 of the tubular portion of the inner cap with the cap 25 when the cap is closed is formed on the inner surface of the opening. The shape of the opening at the tip of the outer cap is not particularly limited, but in order to suitably discharge the foamy liquid to the wall surface, for example, it may be formed by opening obliquely upward as shown in FIG. Alternatively, as shown in FIG. 8, an opening 11 is provided facing upward, and an outer wall of the opening is formed such that a wall surface is formed in a bendable manner such as a bellows-like 111, and a tip 113 is opened. The outer insert 112 may be inserted. Further, the outer cap may have any shape as long as it can smoothly discharge the foamy liquid, and for example, it is preferably formed into a dome shape as a whole.

The container body must be made of a material that presses the barrel to deform the container once and quickly restores its original shape when the pressing is released. Those formed of thermoplastic resin such as polypropylene, polyethylene, polyethylene terephthalate, polyvinyl chloride, and laminates of these are preferably used, and the wall surface may be transparent or opaque, but the internal volume can be visually checked to some extent. In order to make it possible, colored or non-colored and transparent or translucent are preferable. In addition, since the material forming the cap needs to be airtightly engaged with the container body and with the inner cap and the outer cap, for example, a thermoplastic resin such as polypropylene or polyethylene is used. Is preferably used.

FIG. 3 shows a state in which liquid is stored in the foam liquid squeezing container of the present invention. It is necessary to provide a space 43 of air, for example, about 1/4 to 1/5 of the entire container, above the container without being filled with the liquid 42 inside the container body. In use, by pressing (arrow) the wall surface of the container body 4, the liquid 42 is pushed up through the pipe 35 to below the screen in the inner cap. On the other hand, the air above the container reaches the lower part of the screen in the inner cap through the gap of the vertical groove 34 formed between the pipe 35 and the pipe joint 3, and merges with the liquid to form bubbles. Start conversion. Further, by continuing to press the wall surface of the container, the mixed liquid and air pass through the screen portion to become a finer foam liquid, and pass through the opening 26 of the tubular portion 24 to form the outer cap. It is discharged from the opening 11.

Next, when the pressed state of the container body is released, the inside of the container body becomes negative pressure, and the air enters the container through the opening 11. At this time, the vent hole communicating with the pipe 35 from the opening 26 of the tubular portion through the two screens is filled with the foam liquid, and the ball 52 supports the check valve mechanism communicating with the opening 11 of the outer cap. Since it is in the state of being supported by the portion 53, the air from the outside quickly enters the container body through the gap 55 of the check valve mechanism.

That is, according to the foamed liquid squeezing container of the present invention, the discharge of the foamed liquid and the suction of air from the outside are controlled by separate mechanisms, so that the wall surface of the container is pressed and released. The operation is extremely fast, and the liquid and air are always mixed at a constant ratio, and by passing through two screens with similar meshes, a uniform and fine foam liquid can be easily obtained. It will be released quickly by the operation.

Although the method of use in the upright state has been described above, it is easily understood from the structure of the container that the bubble-like liquid squeezing container of the present invention can be used in the inverted state. Will be done.

Further, according to another embodiment of the present invention, the twist cap has a sound producing boss projecting on the inner cap partition wall, and a wall surface of the central tubular portion is provided in the vicinity of the sound producing boss. Forming a first stopper projecting toward the peripheral wall from the above, and the tip of the sound producing boss can be overcome on the inner surface of the outer cap in a state where the tip of the sound producing boss exceeds the second partition wall. (1) A bubble-like liquid squeezing container is provided in which a second stopper having a U-shaped plane is formed to be engaged with the stopper in a surface contact state.

According to this embodiment, as shown in FIG. 1, FIG. 4, FIG. 5 and FIG. 7, a sound producing boss 61 is provided on the partition wall 29 of the inner cap so as to project therefrom. In the vicinity of, the stoppers 62a and 62b for restricting the opened / closed state of the twist cap are formed so as to protrude from the central tubular wall surface 27 toward the peripheral wall 22. The stoppers 62a and 62b are formed on the inner surface of the outer cap. A stopper 63 having a planar U-shaped partition over which the tip of the sound producing boss 61 can be overcome is formed downward, and the stopper 63 is provided on the opposite side of the sound producing boss beyond the second partition wall 65. The second partition wall 65 and the stopper 62 are configured to be engaged with each other in a surface contact state at the same time when the first partition wall 64 makes a knocking sound.

That is, the stopper 62a of the inner cap is used to set the opening 11 when the outer cap is rotated to the open state so that it is always in a place where it can be easily used. This has a particularly important meaning when it is formed into a flat shape, and the state in which the stopper 62a and the second partition wall 65 of the stopper of the outer cap are in contact with each other (see FIG. 7) provides a suitable opened state. means. Also, the other stopper 62b of the inner cap may be over-tightened when the outer cap is closed and the screw fitting is overrun, or when the outer cap is pivoted to be opened in the next use. , It is provided to prevent the inner cap and the outer cap from screwing off when trying to open them with a strong force, and the first partition wall 64 of the stopper of the outer cap abuts and is overtightened. Will be prevented. The stoppers 62a and 62b do not necessarily have to be formed separately, but may be formed in a fan shape in which the stoppers 62a and 62b are combined.

The shape of the sound producing boss is formed on the partition wall 29 of the inner cap as a rod-shaped body having a repulsive elasticity at the tip, but the shape may be deformed by repeated actuation of the twist cap. It is preferable that the skirt is provided in a state in which the skirt is widened in the rotation direction as shown in FIGS. 4 and 6 in order to have a moderate impact resilience. Therefore, according to this embodiment, the open state and the closed state of the twist cap can be easily confirmed by the clicking sound of the sound emitting boss.
