Definitions
- the present invention relates to an inner bag used for a metal or plastic cylindrical container having a relatively large capacity such as a tank or a drum can, and a composite container using the same.
- a flat interior bag 21 is used in which the peripheral edges (left and right end portions 23 and bottom portion 24) of the two films 22 are closed to form a bag.
- the width of the inner bag is approximately half the inner circumference of the cylindrical container, and the volume of the inner bag is almost the same as the volume of the cylindrical container.
- the film thickness is about 0.01 to 0.5 mm, but since the container bears the force applied to the inner bag due to the weight of the filling material, the inner bag is not usually damaged by the weight of the filling material.
- the inner bag When filling the inner bag housed in the cylindrical container with filling, the inner bag is first inserted into the cylindrical container, but as described above, the width of the inner bag is approximately half the inner circumference of the cylindrical container. There is. In other words, because it is a flat flat bag whose width is longer than the inner diameter (or diameter) of the cylindrical container, it is stored with the center of the bottom of the inner bag bent at the bottom of the cylindrical container (U-shaped or S-shaped in plan view). It will be in the form). When the inner bag is filled with a filling in this state, the bottom of the inner bag is maintained in a bent state when the sides (or front and back) of the inner bag are expanded and inflated by the weight of the filling, and the inner bag is filled.
- the lower part could not be sufficiently expanded inside the cylindrical container, and the inner bag was tilted and fell down inside the cylindrical container, so that the inner bag could not be filled with the filling.
- the inner bag containing the filling is lifted and the center of the bottom of the inner bag is lifted. It is necessary to eliminate the bending in the vicinity and align the bottom of the inner bag with the center of the bottom of the cylindrical container, but when holding it up, the weight of the filling may cause the film to stretch and lead to a broken bag. ..
- Patent Document 1 states that the inner body bag for a container has a trapezoidal shape in which the lower part of the inner body bag narrows downward, and the length of the short side of the trapezoid is 0.8 to 1. It is stated that it is twice as high and the height of the trapezoid is 0.4 to 0.6 times the inner diameter of the container. Further, Patent Document 1 describes that such a configuration prevents the lower portion of the inner body bag from bending when the inner body bag is inserted into the container, and that the inner body bag is located substantially at the center of the bottom of the container. ing.

And the back) are evenly spread and swelled, allowing the interior bag to be filled with filling. Since it is difficult to strictly position the bottom of the inner bag so as to pass over the center of the bottom of the cylindrical container, the bottom of the inner bag is centered within 10% of the center of the bottom of the cylindrical container. It suffices to pass over the part, preferably the distance from the center on the bottom surface of the cylindrical container is within 5%, and more preferably the distance from the center on the bottom surface of the cylindrical container is 3.
