Abstract

PURPOSE:To elastically restore a body part of a container at a higher speed to facilitate a continuous foam release operation by a method wherein a foam release path and an outside air suction path are completely separated from each other in a body squeeze-type foam release container. CONSTITUTION:A foam release container is mainly composed of a container body 1 having a body part 2 that can be elastically squeezed, a cap-form member fitted over a mouth-neck part of the container body, a member 20 with a pipe fitted under the member, and a head member 30 fitted on the member. A foam release path is formed by a pouring cylinder 8 provided in the center of the top wall of the cap-form member, a pipe fitting cylinder 21, and a nozzle 36. A foam-producing device is provided in the foam release path. On the other hand, an outside air suction path is formed by a first vertical groove 13 and a second vertical groove 37 that are continuously projected at a part of the fitting surface of a first fitting cylinder 10 with a second cylinder 33, a vent hole 12, and an outside air suction valve 28. The rotation of the head member interrupts the communication between the first vertical groove and the second vertical groove and the communication between the pouring cylinder 8 and the nozzle 36.

2. Description of the Related Art As a body pressure type foam discharge container, for example, a container disclosed in Japanese Utility Model Laid-Open No. 5-54304 is known. The container is a cap provided with a foaming member fitting cylinder penetrating through the center of the top wall at the mouth neck of the container body having an elastically squeezable body, and an outside air intake valve provided at the cylinder side lateral top wall part. The liquid-flowing pipe from the lower part of the foaming member fitting cylinder into the container body, and the peripheral wall of the nozzle-equipped member is screwed into the fitting cylinder rising from the outer circumference of the top wall of the cap-like member. Let's combine
By the screwing of the member, the plug standing up from the upper end of the foaming member fitting cylinder fits into the fitting cylinder hanging from the peripheral edge of the nozzle hole base end of the member with nozzle to seal the nozzle hole, and When the screw is lifted, the plug is removed to open the base end of the nozzle hole, and by squeezing the body in this state, air above the liquid level in the container passes through the groove formed in the inner surface of the foaming member fitting cylinder, and Liquid is introduced into the fitting cylinders through the pipes, mixed by passing through a foaming member, foamed and discharged from the nozzle hole, and by squeezing and releasing the body portion in this state, the nozzle hole and the outside air are released. The outside air enters the container body through the suction valve, and the negative pressure inside the container body due to the decrease of the liquid is eliminated.

[0003]

In the conventional container described above, since the outside air is sucked in when the body is elastically restored by utilizing a part of the foam discharge path having the foaming member, the resistance when the outside air passes through the foaming member. It takes a long time to restore the elasticity of the body part, and thus there is a drawback that the operation is delayed when the body part of the container body is continuously elastically squeezed.

According to the present invention, the foam discharge passage is completely separated from the outside air suction passage to facilitate the above continuous operation, and the head member can be rotated with respect to the cap member to open and close the both passages so that the container body can be collapsed. Also, it is provided so that liquid leakage does not occur, and the number of constituent members is relatively small and simple so that the respective constituent members can be easily assembled.

[0019]

The present invention has the above-described structure, and since the foam discharge path formed by the spout cylinder 8 and the nozzle 36 and the outside air suction path are completely distinguished from each other, the outside air at the time of elastic recovery of the trunk is restored. At the time of inhalation, the foaming member in the foam discharge path does not hinder the inhalation of the outside air at all, so that the inhalation of the outside air can be performed quickly, and thus the continuous operation of releasing the bubbles can be performed quickly. Further, the main members are the container body 1, the cap-shaped member 4, and the pipe-equipped member.
Since the foam discharge container can be formed by the head member 20 and the head member 30 and the members can be fitted with each other with a simple structure, the assembly can be performed very easily and quickly.

In the case of the first aspect of the present invention, the head member 30 is further rotated with respect to the cap-shaped member 4 to shut off the communication between the spout cylinder 8 and the nozzle 36, and the first and second vertical grooves 13, 37. Therefore, when the communication is cut off, the container does not fall down and the liquid does not leak. Also, in the case of the second aspect of the invention, a plurality of pipes are erected from the upper end surface of the pipe fitting cylinder 21 to the lower surface of the vent hole 12. The upper surface of the flange plate 46 attached to the upper end of the threaded piece 45 is elastically squeezed to close the vent hole 12 and the head member 30 is rotated with respect to the cap-shaped member 4 to rotate the spout cylinder 8 and the nozzle.
Since it is provided so as to block the communication with 36, it is possible to prevent liquid leakage when the container falls, as in the case of the first embodiment, and further, as described above, the vent hole formed in the top wall of the cap-shaped member 4. 12
And a plurality of elastic threaded pieces 45 rising from the upper end surface of the pipe fitting cylinder 21 of the member 20 with a pipe ... A flange plate 46 attached to the upper end
Since the upper surface of the flange plate is elastically brought into pressure contact with the lower surface of the vent hole 12 to form the outside air intake valve 28, the configuration thereof is smaller than that in the case where the outside air intake valve is formed by a ball valve or the like, and accordingly, the pipe-equipped member 20 of The configuration can also be simplified.
