[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container capable of suitably discharging and discharging contents such as a liquid, a viscous material, and a powder from a discharge port provided in the container.

[0002]

2. Description of the Related Art Conventionally, when a spout / discharge port is attached to one surface of a container, the spout / exhaust port attachment portion is formed in a concave shape so that the spout / discharge port is used when storing and transporting the container. Containers that are placed on the bottom surface of the container and are used to fill the container with contents or discharge the contents to the outside of the container, draw out the concave portion in a convex shape, and project the injection port are used in various fields. .

However, depending on the shape of the spout / discharge port, the material of the container body, the size of the opening of the outer container when used as a bag-in-box inner container, etc., it is difficult to perform the work of drawing out the concave portion in a convex shape. There is also
If the pouring / discharging port provided on the top surface of the container is separated from the side of the container, the contents in the container may be easily spilled around the container when the contents are discharged.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and facilitates the operation of pulling out a concave portion, to which a spout of a container is attached, in a convex shape. It is an object of the present invention to provide a container provided with an auxiliary tool capable of preventing the occurrence of the problem.

[0005]

According to the present invention, in order to achieve the above object, a spout port attached to a concave portion formed on one surface of a container body is always accommodated in the concave portion. When pouring and discharging, by pulling out the concave portion in a convex shape, a container where the pouring and discharging port protrudes,
A container is provided wherein a tongue member is attached to the pouring / discharging port.

Here, it is more preferable that the tongue member has flexibility, and it is more preferable that the container is a bag-in-box inner container.

Further, the spout has a threaded portion for screwing a cap, the tongue member has a ring portion, and the ring portion is fitted below the threaded portion, and the spout is connected to the spout. It is more preferable that the cap is pressed and fixed to the spout by the screwed cap. Here, the inner diameter of the ring portion of the tongue member is formed so as to be smaller than the outer diameter of the threaded portion of the spout, or the tongue member projects to the inside of the ring on the inner surface of the ring portion. It is more preferable that the projection is provided so that the inner diameter of the ring portion is intermittently smaller than the outer diameter of the threaded portion of the spout.

That is, the container of the present invention is a container in which a concave portion formed in the container main body is drawn out in a convex shape so that a spout / discharge port attached to the concave portion protrudes, and a tongue member is attached to the spout / discharge port. By this, the concave portion of the container body can be pulled up in a convex shape by holding the tongue member, so that the work of pulling out the concave portion becomes easy, and when the contents are discharged, the contents are passed through the pouring and discharging port and the tongue member is discharged. , The contents can be prevented from spilling around.

Here, if the tongue member is flexible, it may be bent or curved so as not to protrude from the recess when the spout is accommodated in the recess. Because it is possible, it is more suitable. And, in the case of a bag-in-box inner container, depending on the size of the opening of the outer container, etc., it may be particularly difficult to pull out the concave portion, so the container of the present invention is more suitable as a bag-in-box inner container, In particular, if the tongue member has flexibility, the tongue member as well as the injection port can be stored in the recess so as not to protrude from the outer container, which is more preferable.

The spout has a threaded portion for screwing a cap, the tongue member has a ring portion, the ring portion is fitted below the threaded portion, and the threaded portion is screwed into the threaded portion. When the cap is formed so as to be pressed and fixed to the injection port by the attached cap, the integration between the injection port and the tongue member is enhanced, and the work of lifting the concave portion to a convex shape becomes easier.

Further, the inner diameter of the ring portion of the tongue member may be formed so as to be smaller than the outer diameter of the threaded portion of the spout, or the tongue member may project from the inner surface of the ring portion to the inside of the ring. If the inner diameter of the ring portion is formed so as to be intermittently smaller than the outer diameter of the threaded portion of the spout, the bellows member can be removed by simply tilting the container after removing the cap. On the other hand, for example, when the contents of the container have been discharged and the container is discarded, the tongue member can be pulled off and removed from the pouring and discharging port, which is more preferable.
