Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a creamy substance pouring container in which a creamy substance or the like in a container body is poured out by body squeezing.

"Problems to be solved by conventional techniques and devices" From a peripheral edge of a central portion of a container body having a squeezable body portion and a donut-shaped flange mounted on a top portion of the container body so as to close the mouth portion, An intake member having a vertical groove recessed therein and a locking shaft protruding from the outer surface, and an opening member provided with a proper number of discharge ports in the circumferential direction on the flange; An intake valve body that closes the intake cylinder from the lower surface, and a cap-shaped elastically deformable top wall whose inner peripheral surface is joined to the outer surface of the intake cylinder and engages the locking shaft from the lower surface. A squeeze container has been proposed which is composed of a discharge valve body that is rotatably fitted to the neck portion of the container body by penetrating a spout tube for forming a spout that has a hook-shaped lock member to mate with. .

In the above-mentioned container, the valve mechanism for liquid pouring and intake can be formed by a small number of parts of the mouth member, the intake valve body, and the discharge valve body, and since these parts are all simple in shape, the structure can be remarkably simplified,
Therefore, processing and assembling are easy, and it can be provided at a low cost. Further, the operation for pouring the liquid does not require any trouble because the discharge valve body is rotated to unlock the mouth member. Since the liquid is not poured out even if the liquid is squeezed unless the lock is released, it is an excellent one having various effects such as the possibility of inadvertently leaking the liquid.

However, in the above-mentioned container, since the intake valve body is attached to the intake cylinder located at the lower part of the outlet, the liquid remaining in the outlet during intake may be returned to the container body through the intake valve body. is there. Since a creamy substance generally has a high liquid viscosity, when the container as described above is used, the creamy substance may be clogged in the vertical groove of the intake cylinder or the like to prevent good intake.

The present invention has been made in view of the above-mentioned points, and generally, even when a highly viscous creamy material is stored, good inhalation can be performed, good liquid can be poured out, and the content is inadvertently discharged. The present invention proposes an excellent pour-out container for creamy substances, etc.

[Means for Solving the Problems] In order to achieve the above object, the creamy substance pouring container according to the present invention has a container body 1 having a body part 5 that can be elastically squeezed.
And a first non-rotatably externally fitted to the mouth / neck portion 7 of the container body.
An inner cap 2 in which a peripheral wall 10 is hung from a peripheral edge of a first top wall 11 and a cap-shaped ridge 12 is erected from a central portion of the first top wall and a first short tubular portion 13 is erected from an outer peripheral portion thereof, and The second peripheral wall 19 is non-rotatably fitted onto the first short cylindrical portion, and the inner peripheral lower edge of the inward flange-shaped elastic valve plate 20 attached to the upper end of the second peripheral wall is attached to the cap-shaped ridge. The discharge valve 21 is formed by being pressed against the upper surface, and the outside air suction valve 23 is formed by pressing the outer surface of the elastic valve cylinder 22 vertically extending from the outer peripheral portion of the lower surface of the elastic valve plate against the inner surface of the first short cylinder portion. The valve member 3 and the outer cap 4 in which a third peripheral wall 26 rotatably fitted to the first peripheral wall is hung from a peripheral edge of a third top wall 28 with a central through hole 27. Through hole 32 in the first top wall portion between the ridge and the cap-shaped ridge.
And an outside air suction passage is formed between the outer surface of the inner cap and the inner surfaces of the second peripheral wall and the third peripheral wall facing the inner cap, and the upper edge of the inner peripheral portion of the elastic valve plate and the through hole of the third top wall. By rotating the outer cap with respect to the inner cap on the lower edge,
First and second portions that are detachably engaged with each other to prevent the lower edge of the inner peripheral portion of the elastic valve plate from separating from the upper surface of the cap-shaped ridge.
It is characterized in that a plurality of engaging projections 34, 35 are provided in the circumferential direction.

[Operation] For example, when the outer cap 4 is rotated in the forward direction with respect to the inner cap 2 from the state shown in FIGS.
34 engages with the second engagement protrusion 35. That is, the lower surface of the second engaging projection elastically rides on the upper surface of the first engaging projection.

As a result, as shown in FIG. 1, the lower edge of the inner peripheral portion of the elastic valve plate 20 is strongly pressed against the upper surface of the cap-shaped ridge 12, and the contents whose pressure has been increased by squeezing the body 5 acts on the elastic valve plate. However, the lower edge of the inner peripheral portion does not separate from the upper surface of the cap-shaped ridge. That is, the discharge valve 21 is locked in the closed state.

On the other hand, when the outer cap is rotated in the opposite direction from the above state, the engagement of the first engaging protrusion with the second engaging protrusion is released this time, and the locked state of the discharge valve is released (FIG. 2). And FIG. 3).

As a result, when the container body 1 is tilted and the body is squeezed, the pressurized content that has passed through the through hole 32 presses the elastic valve plate, opens the discharge valve, and is discharged to the outside. When the compression is released, the discharge valve is closed due to the elastic restoring force of the elastic valve plate, etc., and the outside air intake valve 23 is opened due to the negative pressure in the container body, and the air from the outside air intake passage forms the through hole. The negative pressure is eliminated by being sucked into the main body of the container. After this, the outside air intake valve also closes due to its own elastic restoring force, and eventually communication with the outside inside the container body 1 is cut off.
