Description

[Detailed Description of the Invention] (Industrial Policy Field) The present invention relates to a container, and more specifically, to a container capable of discharging air accumulated in the shoulder of the container body when the inside of the container body is filled with contents. Regarding.

(Prior Art) Conventionally, as a container, one described in Japanese Utility Model Publication No. 56-39030 has been proposed.

As shown in FIGS. 6 and 7, this container is in an extended state along the container body body 2 with the contents filled inside the container body 1,
An elastic band 3 is attached to a predetermined position in the central axis direction of the container body body 2 so as to squeeze the container body body 2 when the contents are discharged into the container body 1. In this container, when the contents filled inside the container body 1 are discharged when the container is folded, the elastic band 3 which is in a stretched state along the container body trunk 2 becomes in a contracted state. The air inside the container body 1 is discharged from the discharge port 4 and the filling port 5, and the container body body 2 is squeezed inward between the container body shoulder 6 and the bottom 7, and is smoothly folded and stored. This is how it was done.

(Problem to be solved by the invention) However, with this container, air accumulates inside the shoulder of the container body when the contents are filled inside the container body, so in this state, air is stored separately on the shoulder of the container body. When containers are stacked on top of each other, the containers stacked on top become unstable, causing the inconvenience that even the slightest shock can cause them to collapse. Furthermore, it was extremely dangerous as it could easily collapse.

The present invention has been developed in view of these problems, and it is an object of the present invention to provide a container capable of discharging air accumulated in the shoulder portion of the container body when filling the inside of the container body with contents.

(Means for Solving the Problems) That is, the present invention provides a pressing body that presses the shoulder of the container body when filling the container with contents in a container made of a flexible sheet material formed into a cylindrical shape. This container is characterized in that it is provided on the shoulder of the container body.

(Function of the invention) Therefore, in the container of the present invention, by providing the pressing body that presses the shoulder of the container body on the shoulder of the container body, the shoulder of the container body is pressed when filling the inside with contents. Air that accumulates in the can be expelled.

(Example) Hereinafter, the container of the present invention will be described in detail according to an example shown in the drawings.

Figures 1 to 4 show the container of the present invention.
The figure is a partially cutaway perspective view showing the entire container, FIG. 2 is a side view thereof, FIG. 3 is a plan view thereof, and FIG. 4 is a rear view thereof.

As shown in FIGS. 1, 2, 3, and 4, the container of the present invention uses a waterproof sheet made of polyethylene or polypropylene as a flexible sheet material. It is formed into a cylindrical shape. The container body shoulder 12 is formed with a filling port 15 for filling the inside, and the container body bottom 17 is formed with a discharge port 14 for discharging the contents. It is designed to be discharged. The container body body 12 also prevents the container from bulging in the lateral direction due to the contents when the container is filled with contents, and prevents the container from bulging in the lateral direction due to the contents.
A reinforcing band 13 is attached by sewing or gluing, and is applied to the joint of 1 to reinforce that part. In this embodiment, the reinforcing bands 13 are joined to four locations on the container body trunk 12 over the entire length in the height direction. This reinforcing band 13 has slits 18, 18 at the upper and lower parts, and the slits 18, 18,
An attachment belt 19 is inserted through the container body 18 and its ends are disposed on the bottom 17 and the shoulder of the container body. and,
At the bottom 17 of the container body, each mounting belt 1
A rope 21 is inserted through a rope attachment part 20 provided at the nine ends and narrowed toward the center of the container. Also in the container main body shoulder 16, a lifting rope 22 is inserted through a rope attachment part 20 provided at the end of each attachment belt 19, and the container is lifted up by this rope 22. The container body shoulder 16 of the container configured in this manner is provided with a pressing body 23 that presses the container body shoulder 16 when filling the inside with contents.

As shown in FIGS. 1, 2, 3, and 4, the pressing body 23 is an elastic body attached to the container body shoulder 16 so as to connect the upper ends of the reinforcing band 13. It is. This pressing body 23 is hooked onto the upper end of the reinforcing band 13 to communicate between the respective upper ends. Note that the pressing body 23 may be divided into a plurality of parts, and an end portion may be attached to each upper end of the reinforcing band 13 so as to communicate between the upper ends. The pressing body 23 is expanded by being filled with contents, and its restoring force presses the container body shoulder 16 inward. The pressing body 23 may be anything as long as it has elasticity, such as a rubber band that is hooked onto the upper end of each reinforcing band 13 and connecting the upper ends, or a rubber band that is attached to each upper end of each reinforcing band 13 and attached to the shoulder of the container body. Preferable examples include a rectangular, triangular, or donut-shaped elastic sheet that covers substantially the entire surface of 16. In this example, a rubber band was used. Further, as shown in FIG. 5, the pressing body 23 may be one equipped with a pressing plate provided at both ends with through holes 25 through which the above-mentioned rubber band is inserted. The pressing area increases by that amount, and the container body shoulder 16 can be pressed more efficiently.

Next, the usage status of the container configured in this way will be explained.

First, the contents are filled through the filling port 15 formed in the shoulder 16 of the container main body of the container. When the container body 11 is filled with contents and inflated, each reinforcing band 1 is joined to four points of the container body body 12 along the entire length in the height direction.
The spacing between 3, 13, 13, 13 is expanded, and the reinforcement band 1
The pressing body 23 connecting the upper ends of the members 3, 13, 13, and 13 also changes from a contracted state to an expanded state accordingly. The pressing body 23 that has changed to the extended state presses the container body shoulder 16 inward due to its restoring force. Therefore, the air accumulated in the container body shoulder 16 is pushed out from the filling port 15, and the contents are filled in the container body shoulder 16 with no gap left.

(Effects of the invention) As detailed above, in the container of the present invention, by providing the pressing body on the shoulder of the container body for pressing the shoulder of the container body, it is possible to easily fill the container with contents. Air accumulated in the shoulder of the container body can be discharged. Therefore, even if another container is stacked on top of the shoulder of this container body after filling the inside with contents, the container stacked on top will remain stable and will not collapse due to a small impact, making it safe. It is possible to perform stacking work.
