Description

[Detailed explanation of the idea] "Industrial application field" This case concerns a cream-like substance dispensing container.

"Prior art" For example, Figure 1a of Japanese Utility Model Application Publication No. 60-24748,
The device shown in b consists of a container body with a mouth and neck erected from the upper end of the body, and an inner peripheral wall that hangs down from the periphery of the top wall, which fits into the inner surface of the mouth and neck, and the suction is drawn from the periphery of the opening in the center of the top wall. The cylinder part is erected, and the inner cap body has a through hole bored in the outer periphery of the top wall, and the peripheral wall hanging from the periphery of the top plate is screwed together with the outer surface of the mouth and neck part, and the opening in the center of the top plate is screwed together. an outer cap body in which a spouting cylinder part standing up from the periphery is fitted to the outer surface of the upper end of the suction cylinder part; a discharge valve body for opening and closing the through hole;
It consists of an intake valve body that opens and closes the lower end opening of the intake cylinder, and when the outer cap is screwed up relative to the inner cap body and the upper end of the dispensing cylinder is opened, the body of the container body is elastically squeezed, and the discharge occurs. When the valve body opens, the contents pass through the hole and are discharged from the top opening of the spout cylinder, and when the compression is released, the intake valve body opens and outside air flows into the body from the suction cylinder, causing air to flow into the body. It is formed to eliminate negative pressure.

``Problem to be solved by the invention'' In the conventional example described above, since the upper end surface of the intake cylinder is always open, there is a disadvantage that dust etc. can easily enter the intake cylinder and become dirty. On the other hand, depending on how much the outer cap is screwed up, the degree of opening of the spout cylinder, that is, the size of the gap between the outer surface of the suction cylinder and the inner surface of the spout cylinder, changes, and the opening of the spout cylinder changes. Since the condition cannot be determined at a glance, users may use the dispensing barrel without noticing that it has a large opening, and may accidentally dispense more cream-like material than necessary.

In the present invention, an engaging protrusion and an engaging recess provided around the outer surface of the peripheral wall of the inner cap and the inner surface of the peripheral wall of the outer cap are engaged with each other, so that the peripheral walls of both the inner and outer caps are rotatably fitted, And, in the spout cylinder part and the suction cylinder part,
By forming an outside air intake passage and a creamy substance dispensing passage that are opened and closed by rotating the outer cap relative to the inner cap, it is possible to prevent dust from entering the outside air intake passage when not in use, and to dispense an appropriate amount of creamy substance. It is now possible to pour things into.
