ABSTRACT:
TECHNICAL FIELD
The present invention relates to a repetitively useable container inner bag, and more particularly to an inner bag for a container that is used upon bulk transportation of cargo (grain), for instance, by shipping.
BACKGROUND ART
Conventionally, in the case of transporting bulk grain by using shipping containers, first, bulk grain is filled, at the production district, in container inner bags that are provided along an inner surface of containers. The container inner bags are formed into an elongated rectangular parallelepiped shape and made of synthetic resin, such as vinyl chloride, polyethylene and the like. The containers having the inner bags filled with the bulk grain are then transported to destinations, respectively. Doors of the containers transported are opened and the bulk grain within the inner bags is taken out by cutting out a front portion of the inner bags and transferred to storage facilities.
Further, in Japanese Patent Application First Publication (KOKAI) No. 7-223673, there has been proposed a parallelepiped-shaped container inner bag of a two-piece type that includes a front wall portion and a rear elongated rectangular portion. The front wall portion is cut to form a takeout aperture and then discarded. A new front wall portion is mounted to the rear elongated rectangular portion, whereby the container inner bag can be partly reused.
Specifically, the inner bag is made of synthetic resin and has a generally rectangular parallelepiped shape as shown in FIG.

. One end portion
201
of the inner bag is formed at its upper part with a content insertion aperture
202
through which a large amount of content can be filled into the inner bag. After taking out the content from the inner bag, the front portion including a broken portion
203
that is cut out to form an opening, is removed from the remaining portion
204
and then a new front portion is fitted to the remaining portion. Thus, the inner bag has a reusable construction.
Such the partly reusable inner bag has been proposed in order to eliminate the following disadvantages of the conventionally used inner bag of an integral-sealing type by adopting a split-mounting structure. Since the conventionally used inner bag must be cut to form an aperture for taking out the content from the inner bag by using a cutting member such as a knife, the inner bag must be discarded once used. It will be required to prepare a new inner bag for the subsequent bulk shipment, causing increase in cost. However, the partly reusable inner bag proposed is constructed such that the portion, i.e., the front portion, is cut to form the content takeout aperture by using the cutting member such as a knife as well as the conventional inner bag. The front portion cut is discarded and then replaced by the new one for reuse of the whole inner bag. Thus, the partly reusable inner bag proposed requires complicated structural elements due to forming and mounting means such as sewing for withstanding the cargo weight (for preventing bulge and deformation of the bag), and further necessitates members required for the partial replacement and the mounting cost thereof.
An object of the present invention is to provide a container inner bag adapted to be repetitively used as a whole in ship transportation and discharge operation of a bulk container for a large amount of grain such as malt.
Another object of the present invention is to provide a container inner bag capable of being easily cleaned.
A further object of the present invention is to provide a container inner bag exhibiting a good installation (mounting and removal) performance.
A still further object of the present invention is to provide a container inner bag having a good performance in insertion and takeout of the content.
DISCLOSURE OF INVENTION
According to one aspect of the present invention, there is provided a container inner bag mounted into a freight container and filled with a large amount of content. The container inner bag is made of a synthetic resin sheet and has an elongated rectangular parallelepiped shape including at least a bottom wall, front and rear walls and left and right side walls.
The elongated rectangular parallelepiped-shaped container inner bag is cut along at least ridges at which the front wall encounters the left and right side walls and ridges at which the rear wall encounters the left and right side walls. The front wall and the left and right side walls are adapted to be joined and separated along the ridges formed between the front wall and the left and right side walls by connecting and separating means such as a fastener. The rear wall and the left and right side walls are adapted to be joined and separated along the ridges formed between the rear wall and the left and right side walls by connecting and separating means such as a fastener. The front wall has, at an upper portion thereof, a cut portion adapted to form a content insertion opening through which the content is filled into the bag, and, at a lower portion thereof, a cut portion adapted to form a content takeout opening through which the content is taken out of the bag. These cut portions are adapted to be joined and separated by connecting and separating means such as a fastener, respectively.
Upon inserting the content into the bag, the cut portion adapted to form the content insertion opening is separated by the connecting and separating means to form the content insertion opening and then the content is filled into the bag through the content insertion opening. After the insertion of the content, the cut portion is joined by the connecting and separating means to close the content insertion opening. Upon taking the content out of the bag, the cut portion adapted to form a content takeout opening is separated by the connecting and separating means to form the content takeout opening and then the content is taken out of the bag through the content takeout opening. After taking out the content, the cut portion is joined by the connecting and separating means to close the content takeout opening. Thus, the container inner bag is so constructed as to be repetitively usable. Further, since the container inner bag is adapted to be developed into one flat sheet made of synthetic resin, the container inner bag can be readily cleaned.
According to another aspect of the present invention, the container inner bag has a hexahedral structure including the bottom wall, the front and rear walls, the left and right side walls and a top wall. The front and rear walls and the left and right side walls are so constructed as to be joined and separated by the respective connecting and separating means along the ridges formed between the front wall and the left and right side walls and between the rear wall and the left and right side walls. Further, the front and rear walls, the left and right side walls and the top wall are so constructed as to be joined and separated by the connecting and separating means along three ridges among four ridges formed between the front and rear walls and the left and right side walls and the top wall. Therefore, the container inner bag can effectively prevent dust from entering thereinto and the content from leaking out thereof.
According to a further aspect of the present invention, the container inner bag has a pentahedral structure including the bottom wall, the front and rear walls and the left and right side walls. The front and rear walls and the left and right side walls are so constructed as to be joined and separated by the connecting and separating means along the ridges formed between the front wall and the left and right side walls and the ridges formed between the rear wall and the left and right side walls, respectively. Therefore, the pentahedral container inner bag can be structurally simplified and easily handled as compared with the hexahedral one.
According to a still further aspect of the present invention, the cut portion adapted to form the content insertion opening, of the container inner bag, includes a first cut segment dispo
