Description

[Detailed explanation of the invention] "Industrial application field" This invention stores a cream-like substance and can be poured out by elastic compression of the body. This relates to a squeeze container provided to eliminate pressure build-up.

``Prior art'' As a cap for this kind of container,
A cap disclosed in Japanese Patent No. 20656 is known. The cap has a dispensing tube erected from the center of the top wall, a first intake hole is bored in the top wall of the cap on the side of the dispensing tube, and a rubber plate is fitted deep inside the cap. A spouting passage opened by liquid pressure from below the rubber plate is formed in the lower part of the spouting cylinder of the rubber plate, and a second intake hole is bored in the rubber plate part below the first intake hole, and The lower surface of the second intake hole is closed by an elastic piece that protrudes from the lower surface of the rubber plate so that it can be opened by creating a negative pressure inside the cap.

``Problem to be solved by the invention'' The conventional cap described above has a rubber plate that is fitted into the back of the cap, a spout passage that opens and closes with elasticity, a second intake hole, and an elastic band that elastically opens and closes the second intake hole. Since the pieces were biased, it was difficult to form the rubber plate.

The present invention eliminates such drawbacks, has a simple structure and is easy to manufacture, and is provided so that stored items can be poured out and outside air can be reliably sucked in using a small number of members.

"Means for Solving the Problems" A container body 1 having a body 4 that can be elastically compressed and having a neck 6 erected upward, a cap 2 hermetically fitted to the neck 6; Cap top wall 8
The upper part of the cylindrical body 19 with openings on both upper and lower ends is fitted into the lower part of the spouting cylinder 10 that stands up from the cylindrical body, and the cap top wall 8 is perforated with the upper surface of the outer peripheral part of the elastic outward flange 20 attached to the lower end of the cylindrical body. It consists of an intake valve body 3 that seals the lower surface of the intake hole 14 provided, and the above-mentioned spout cylinder 1
A discharge valve body 12 is provided in the upper part of the spout cylinder 12 and is supported in a vertically movable manner at the tip of an elastic support piece 17 that projects in an arc shape from the inner surface of the spout cylinder along one circumferential direction of the inner surface. was seated on the upper end surface of the cylindrical body 19 to form a discharge valve.

"Operation" When the body 4 of the container body 1 is elastically squeezed from the state shown in FIG. 1, the discharge valve body 12 shown in FIG.
8 is opened, the stored material is poured out from the spout 9, and the discharge valve is closed when the pouring is completed. When the body part 4 is released, the body part elastically restores itself, and as a result of the negative pressure inside the container due to the elastic restoration, the elastic outward flange 20 below the intake hole 14 opens.
The outer peripheral portion is separated from the lower surface of the intake hole against its elasticity, and outside air enters the container body 1 through the intake hole 14 to eliminate the negative pressure, and at the same time, the elastic outward flange 20 again seals the lower surface of the intake hole.

``Embodiment'' An embodiment of the present invention will be described below with reference to the attached drawings. In the figure, 1 is a container body, 2 is a cap body attached to the mouth of this container body 1, and 3 is a top wall of this cap body 2. This is an intake valve body mounted on the back surface, and each of these members is integrally molded from a synthetic resin material.

The container body 1 is made of a soft synthetic resin material, and its body 4 has elasticity. Therefore, by squeezing the body 4, the stored contents can be pressurized and poured out from the mouth 5. Reference numeral 6 indicates a mouth and neck portion, and a thread 7 is formed on the outer peripheral surface of the mouth and neck portion.

The cap body 2 has a spout 9 from the center of the top wall 8.
A pouring tube 10 for forming is installed vertically through the pouring tube 1.
An engagement groove 11 is provided on the inner periphery of the lower part of the 0, and a discharge valve body 12 is integrally provided in the spout cylinder 10 above the engagement groove 11. An inner cylinder 13 to be fitted inside is installed vertically, and this inner cylinder 13
A small-diameter intake hole 14 is bored in the middle of the spouting tube 10, and the screw groove 16 of the peripheral wall 15 is screwed into the screw thread 7 to be attached to the outer surface of the container mouth neck 6.

The discharge valve body 12 is a disc body with a spherical back surface, and has an arc shape on both sides that protrudes along one circumferential direction of the inner surface from both inner surfaces of the spout cylinder 10 which are displaced by approximately 90 degrees. It is supported by elongated elastic support pieces 17, 17 so as to be swingable in the vertical direction.

The intake valve body 3 has a cylindrical body 19 for forming the discharge hole 18.
A relatively wide elastic outward flange 20 with a thin peripheral edge curved upward is provided at the lower end, and the cylindrical body 1
9 is attached to the back surface of the top wall 8 of the cap body 2 by engaging the engagement protrusion 21 protruding from the outer circumference with the engagement groove 11. In this attached state, the discharge hole 18 is connected to the discharge valve. It is sealed by elastic pressure contact with the back surface of the body 12, and the thin peripheral edge of the elastic outward flange 20 closes and seals the intake hole 14 from the bottom surface.

``Effect of the invention'' According to the above-mentioned present invention, the valve mechanism for dispensing stored contents and inhaling air can be formed by two members, the cap body 2 and the intake valve body 3, and since each of these members has a simple shape, the structure is extremely simple. In addition, the assembly of these two members is extremely easy since it is only necessary to fit the upper part of the cylinder 10 of the intake valve body 3 into the lower part of the spout cylinder 10 of the cap 2. Since the cap 2 and the intake valve body 3 can be integrally connected, there is no possibility that the intake valve body 3 will be misaligned or come off when the cap is attached to or removed from the container body. Furthermore, since the discharge valve body 12 has a structure in which a small disc body is supported by elongated elastic support pieces 17, 17, it has excellent responsiveness to pressurized stored items.
Even with a relatively weak squeezing operation, it is possible to reliably open the valve and pour out.

Furthermore, the intake valve body 3 is formed by attaching an elastic outward flange 20 to the lower end of a cylindrical body 19, and the cylindrical body 19 is fitted into the lower part of the cylindrical hole of the cap dispensing cylinder 10, and the upper end surface thereof is inserted. The above-mentioned discharge valve body 12 is seated to serve as a discharge valve, and the lower surface of the intake hole 14 formed in the cap top wall 8 is sealed at the upper surface of the outer circumference of the elastic outward flange 20 to serve as an intake valve. Valve body 3
serves as an intake valve body as well as a valve seat for the discharge valve, thereby simplifying the structures of the discharge valve and the intake valve.
