Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an inner bag of a bag container for powder particles, the container body of which is made of a flexible material.

[0002]

[Problems to be solved by conventional techniques and devices]

 In recent years, as a container for powder and granular material, a woven cloth such as a synthetic resin cloth woven from synthetic resin yarns or fibers such as a synthetic resin monofilament, or a woven cloth coated with or laminated with a resin So-called bag containers made of flexible material have been put to practical use. This bag container is generally provided with a cylindrical filling port on the upper surface of the accommodating portion and a discharging port on the bottom surface in consideration of the filling work and discharging work of the powder and the like.

A flange formed of a rigid material such as a synthetic resin material for the purpose of holding the tubular filling port in an open state and facilitating the connection to the filling port of the filling device when filling the contents into the container. It is conceivable that a frame is attached to the end of the cylindrical filling port and the flange frame is locked to a locking device such as a rail attached to the filling device to keep the cylindrical filling port in the open state. As a result, the filling work is automated (for example, Japanese Utility Model Publication No. 57-53279).

In the above-mentioned container, as means for attaching the flange frame to the tubular filling port, the end of the tubular filling port is fixed to the opening edge portion at the center of the flange frame by adhesion, welding means or stitching means. Generally, the flange frame cannot be removed.

In this case, it is troublesome to attach the flange frame, and it is difficult to remove and replace the flange frame, and it is necessary to transport the flange frame with the unnecessary flange frame attached during transportation and at the destination. There is.

Therefore, the applicant of the present invention has an expandable body at the end of the cylindrical filling port so that the filling flange frame can be easily and detachably attached to the cylindrical filling port with a very simple operation. A container has been proposed (Japanese Patent Application No. 5-13713) in which a tightening means composed of a cord or a cord is provided, and this is tightened and engaged with a cylindrical opening provided on a flange frame.

By the way, such a container for powder and granules has a container body made of woven fabric or the like and an inner bag corresponding to the container body, which is a bag having a double inner and outer structure, in order to ensure moisture resistance and waterproofness. It is generally used.

Further, in this type of bag container, the outer container body made of a relatively strong material is repeatedly used several times, and in this case, the inner bag is filled with the filled powder particles. There is a hygiene problem when the body adheres (especially iron powder) and the content is food, so it is necessary to replace the inner bag each time and use it.

Therefore, if the inner bag is joined and integrated to the outer container body by means such as stitching, it is difficult to replace the inner bag. Therefore, the inner bag is internally mounted without being connected to the container body. It is desirable to do.

However, if the inner bag is not connected to the container body, when the filling flange frame is detachably attached to the tubular filling port as described above, the tubular filling port of the inner bag is also attached to the flange frame. If it is not attached to the tube mouth, the cylindrical bag mouth of the inner bag will fall off and automatic filling will not be possible.

The present invention has been made in view of the above, and as an inner bag of a bag container to which a flange frame is attached and used, the bag container is internally mounted without being connected to the container body and facilitates replacement thereof. The present invention provides an inner bag in which the tubular filling port of the inner bag can be easily and surely attached to the tubular mouth portion of the flange frame.

[0012]

[Means for Solving the Problems]

 The present invention, which solves the above-mentioned problems, is an inner bag made of a synthetic resin film that is installed inside a container body made of a flexible material without being connected to the container body. Has a discharge port, and the end of the cylindrical filling port is provided with a tightening means such as a telescopic body or a cord for tying, and is provided so as to be engageable with a cylindrical port portion such as a flange frame. It is characterized by

[0013]

[Action]

 According to the inner bag of the bag container of the present invention described above, when the filling flange frame is attached to the tubular filling port of the container, the tubular filling port of the inner bag is used together with the tubular filling port of the outer container body. Also, attach it so that it covers the tube mouth of the flange frame.

At this time, not only the tubular filling port of the container body having the fastening means provided at the end, but also the end of the tubular filling port of the inner bag is fastened with an elastic body or a binding cord or the like. Since the means is provided, it can be attached to the tube mouth portion by covering the tube end portion of the flange frame with the mouth end portion and tightening it with the tightening means.

For example, when the fastening means is an elastic body, it can be attached to the barrel opening portion by its elastic force. Further, even when the tightening means provided at the end of the tubular filling port is a string for bundling, cover the end of the tubular filling port of the container body and the inner bag with the tubular port portion. It can be easily attached by the binding action of the string body in the closed state.

Therefore, at the time of automatic filling, the cylindrical filling port of the inner bag does not come off or fall off from the flange frame. Especially when the cylindrical filling port of the container body and the inner bag is put on the cylindrical opening portion of the flange frame from the side opposite to the projecting side and folded back to the outside, the cylindrical filling port It is even more difficult for the end of the to pull out, and the locked state can be maintained well.

Further, the tubular filling port can be detached from the flange frame by expanding the tubular filling port by resisting the elastic force of the elastic body or by releasing the binding of the cord body. The flange frame can be removed.

In addition, since the inner bag is only connected to the outer container body without being connected, only the inner bag that is easily soiled can be pulled out from the container body and replaced during repeated use of the container. Can be used.
