Description

  The present invention relates to a bag container used with a dispenser attached.

In general, containers that contain liquid contents such as shampoo liquid, rinse liquid, cosmetic liquid, and medicine and that are used with a dispenser such as a pump that sucks out the contained contents are known.
For example, Patent Document 1 describes a container with a dispenser having a bottom surface that is inclined downward toward a recess disposed in the center of the bottom.
Patent Documents 2 and 3 describe a container with a dispenser formed using a resin sheet material instead of a plastic or glass hard container.

JP 2006-315744 A JP 2005-132463 A JP 2011-6137 A

According to the container described in Patent Document 1, since the entire peripheral area surrounding the concave portion at the center of the bottom surface is inclined downward, when the contents stored in the container are sucked out by the dispenser, the contents can be sucked out to the end. It is possible to reduce the remaining amount of liquid.
However, since the container described in Patent Document 1 is a hard container, it is costly, difficult to reduce after use, and difficult to contribute to volume reduction of dust.

On the other hand, since the container described in Patent Document 2 is formed using a resin sheet material, the cost can be reduced and the size can be reduced after use, which can contribute to volume reduction of dust. .
By the way, when the portion for storing the contents is formed using a resin sheet material, the portion for storing the contents is deformed when the pressing operation portion of the pump-type dispenser is pushed down. There is a problem that the operation of discharging the ink cannot be performed stably.
In order to solve this problem, in the container described in Patent Document 2, a bar-shaped member extending toward the bottom of the bag-shaped container is provided at the suction port of the pump-type dispenser, and a suction cup or the like is provided at the lower end of the bar-shaped member. An engaging means made of an adhesive material is provided as a fixing means for fixing to the bottom of the bag-like container. According to Patent Document 2, when the container operation part of the pump-type dispenser is pushed down, the stick-like member functions like a stick, so that the push operation part is pushed down while being a flexible bag-like container. It is said that all contents can be discharged.
However, as in Patent Document 2, when a suction cup or an adhesive material is provided as an engaging means, the container bottom may be flat, and if the content is a liquid containing a shampoo liquid surfactant, A liquid may enter between the adhesive member and the bottom portion to reduce the binding force, and the pressing operation may not be performed stably because the lower end portion of the rod-shaped member is displaced from a predetermined position of the container bottom portion during the pressing operation. Further, when the pump-type dispenser is replaced with a new bag-like container containing the contents, the engaging means at the lower end of the rod-like member is more difficult to be joined to the bottom of the new bag-like container. In addition, when carrying a bag-like container by holding a pump-type dispenser, the lower end of the rod-shaped member may be displaced from a predetermined position on the bottom of the container due to vibration or the like, and there is a risk of inconvenience such that the pressing operation cannot be performed stably. There is.

Even in the container described in Patent Document 3, when the pressing operation part of the pump type dispenser is pushed down, the pressing operation part of the pump type dispenser and the bottom part of the container A supporting member is interposed between the two, and the pressing force when the pressing operation unit is pushed down is received by the supporting member.
However, when the pressing force by the pressing operation unit is applied obliquely with respect to the axis of the support member, the lower end portion of the support member is displaced from a predetermined position of the container bottom, and the container is deformed or the pressing operation cannot be performed stably. There are inconveniences such as. In addition, in the container described in Patent Document 3, the flexibility of the container made of resin sheet material is reinforced by providing a reinforcing material that assists the container independence, thereby reducing costs and reducing dust. It is not preferable in terms of achieving a good result.
