DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube-like container made of a flexible material for storing a fluid and sticky fluid such as mayonnaise, ketchup, toothpaste foam and facial cleansing foam.

[0002]

2. Description of the Related Art Conventionally, a tubular container made of a flexible material such as a synthetic resin having a moderate flexibility has been known as a container for a sticky fluid. In such a tubular container, the contents of the fluid can be easily squeezed out from the spout by compressing the container body while holding the container body. However, in such a tubular container, as the amount of the fluid filled in the inside decreases, the tubular container becomes flat as a whole, and only by squeezing the container body with one hand, the fluid can be quickly discharged from the spout. Cannot be squeezed out. For this reason, it is inefficient and time-consuming to discharge a required amount of fluid when the remaining amount of the fluid is reduced, and when the fluid remains in a state biased toward the bottom side in the tubular container, It was also difficult to completely use up the fluid.

Accordingly, various tubular containers have been developed for the purpose of easily squeezing out the fluid in the tubular container even when the amount of the fluid filled in the tubular container is small. For example, JP-A-8-310544
, Registered utility model No. 3041354 or JP-A-8-34453 proposes a tubular container in which a spout for squeezing a fluid is formed above and below a tubular container. Since such a tubular container has a structure in which a spout is provided at each end of the tubular container, even if the fluid whose remaining amount is reduced remains in a state biased to the bottom edge side of the tubular container, the bottom portion is The fluid can be easily discharged from the side spout.

Japanese Patent Application Laid-Open No. HEI 8-119298 proposes a tubular container having a vent formed with a check valve at the bottom of the tubular container. The tubular container and the tubular container proposed in the above-mentioned Japanese Patent Application Laid-Open No. 8-34453 have a large cap for opening and closing the spout and a flat top portion of the cap. The tube-shaped container can be held in a state in which the tube-shaped container is turned upside down with the device facing downward. Accordingly, when these tubular containers are stored, the fluid inside moves to the spout side even when the remaining amount is small, and the fluid always stays in the filled state near the spout. At the same time, in the tubular container proposed in Japanese Patent Application Laid-Open No. HEI 8-119298, the check valve opens and closes in conjunction with the squeezing operation of the fluid because the vent hole is formed on the side opposite to the spout. I do. That is, when grasping the tubular container and squeezing out the fluid, the check valve is held in a closed state, but after squeezing out the fluid, when the tubular container elastically returns, the check valve of the vent hole is closed. When opened, air is supplied into the tubular container. Thereby, air is supplied to the bottom side of the tubular container, and even if the remaining amount of the fluid is reduced, the tubular container is always inflated by the air supplied to the inside, so that the tubular container is squashed. This makes it possible to quickly discharge the fluid retained at the spout portion, and also to completely use up the fluid in the tubular container without leaving it.

The tubular container proposed in Japanese Patent Application Laid-Open No. 8-34453 has a structure in which spouts are formed at the top and bottom, respectively, and large caps that can also be used as a mounting base are screwed to the spouts. Therefore, it is structurally useless. That is, if the purpose is to quickly squeeze out the fluid whose remaining amount is small and completely use it, as proposed in Japanese Patent Application Laid-Open No. 8-119298, a tube-shaped member located on the opposite side to the spout is used. If there is a vent on the bottom side of the container to take in air, the tubular container will always be inflated even if the remaining amount of the fluid is low. The fluid can be used up quickly and completely without exhausting the internal fluid, and there is no structural waste.

However, the tubular container proposed in Japanese Patent Application Laid-Open No. Hei 8-119298 has an opening / closing mechanism for taking in air into the tubular container, which is constituted by a check valve through a thin hinge in a vent hole. I have. This check valve has a structure that allows the inflow of air to the inside and prevents the loss of air to the outside. Therefore, when air is taken into the tubular container, the check valve is moved inward. There is a need. Therefore, when the fluid is filled up to the bottom of the tubular container, not only the check valve cannot move inward, but also when the check valve adheres to the fluid to be filled in the tubular container, There is a possibility that opening and closing of the stop valve may be hindered.

Furthermore, the tubular container proposed in Japanese Patent Application Laid-Open No. 8-119298 has a structure in which the check valve is opened and closed in conjunction with the operation of squeezing the fluid, so that the check valve can be opened and closed arbitrarily. Can not. That is, when the tubular container is elastically restored to its original form after grasping the tubular container, the check valve is opened by utilizing the pressure difference between the inside and outside of the tubular container. When the container is used, the check valve opens and closes and air is introduced into the tubular container. However, depending on the fluid to be filled in the tubular container, when not used for a long time, such as corrosion due to the incorporation of air, it may have a bad effect, and it is rather preferable that no air is mixed into the tubular container. In some cases.

The present invention is intended to solve such a problem, and it is possible to reliably introduce air into a tubular container to quickly squeeze out a fluid having a small remaining amount, and if necessary, An object of the present invention is to provide a tubular container that can easily deaerate the air in the tubular container.
