According to the configuration, when the grains stored in the bag 14 are discharged, the grains and the like are less likely to stagnate on the slanted edge 20 of the bag mouth portion 12 and can be smoothly discharged, and the width of the joint edge 11 of the chuck 13 portion can be reduced. Is widened to reduce damage to the bag mouth portion, and the closing force of the chuck 13 is not reduced.

【Example】

 The grain bag has a rectangular shape that is long in the vertical direction when viewed from the front, and includes an outer bag 7 and an inner bag 14 that fits inside the outer bag 7. The outer bag body 1 of the outer bag 7 is made of a synthetic resin fiber and is made of a woven fabric having an opaque color, for example, beige, green, blue or black. Cut the cloth tube strip into an appropriate length, and wrap the cut bag bottom edge 22 at the lower end of the cloth tube on the front bag surface side or the back bag surface side and integrally sew or join them to form the bag bottom portion Make up. Further, the bag mouth edge 23 of the outer bag mouth portion 3 is folded back inside and wound up, and this is sewn to form a bag mouth.

The outer bag mouth 3 can be opened and closed by attaching the slide fastener 2 to the outer bag mouth 3 over the full width of the bag and moving the opening / closing slider 24 left and right. The fastener end portions 21 at the left and right ends of the slide fastener 2 are made longer than the bag mouth width so as to extend to the outside of the mouth edge 19 as shown in FIG. 2 or from the mouth edge 19 to the bag mouth portion. It can be folded and stored inside 3.

At the center portion of the outer bag mouth portion 3 in the bag mouth width direction, loop-shaped cloth handles 5 are sewn to the bag mouth edges 23 on the front bag surface side and the back bag surface side. A loop-shaped cloth handle 6 is sewn to the bag bottom edge 22 at the center of the bag bottom 4. These grips 5 and 6 can be configured to be easily gripped by protruding outward from the bag mouth portion or the bag bottom portion of the outer bag 7 when gripping.

The inner bag 14 is made of a synthetic resin and is a transparent or semi-transparent and airtight vinyl bag, a polyethylene bag, or the like. The left and right side edges and the bag bottom edge have a front bag surface 9 and a back bag. The joint edges 11 and 25 formed by superimposing and joining the surface 10 are formed to have an appropriate width. The joint edges 11 at the left and right ends of the inner bag mouth 12 are formed by integrally pressing the chuck 13 and the chuck sheet 16 together with the front bag surface 9, the back bag surface 10 and the like. The space between the left and right bag mouths in the bag 13 portion is slightly narrowed, and the inner edge of the joint edge 11 in this bag mouth is formed as an inclined edge 20 to narrow the bag mouth end. By eliminating the corners inside the chuck 13 of No. 12, the amount of stagnation of grains at the time of discharging is reduced. Inside the inner bag mouth part 12, a chuck 13 is provided over the entire width in the left-right direction. The chuck 13 is made of a synthetic resin material and has a hermetically sealed form having a concave ridge 26 and a convex ridge 27 that can be fitted into and out of each other. It can be fitted and closed by pulling it out, and it can be opened by pulling it out.

The chuck 13 is integrally formed along a surface of a chuck sheet 16 made of a synthetic resin film sheet having a length substantially equal to the left-right width of the inner bag mouth and a constant height. The lower end of 16 is electrothermally bonded along the inner surface of the bag mouth of the inner bag 8.

The inner bag mouth portion 12 of the inner bag 14 fitted in the outer bag 7 is set to a height that allows it to be exposed to the upper outer portion than the outer bag mouth portion 3. It is formed so that it can be exposed at a height approximately three times as high as or higher than that.

As shown in FIG. 7, the chuck sheet 16 integrally forming the chuck 13 has a lower end portion adhered to an inner peripheral surface of the mouth end edge 19 of the upper end bag mouth portion of the bag body 8 to form a chuck. The 13 part may be provided so as to be located above and outside the mouth edge 19.

Further, as shown in FIG. 8, the chuck 13 is adhered to the inner peripheral surface of the bag mouth portion of the bag body 8 over the entire height of the chuck sheet 16, so that the chuck 13 is positioned more than the mouth edge 19 of the bag body 8. It may be installed so that it is located inside the bag.

The chuck 13 of such a chuck sheet 16 may have a single-row, single-stage configuration, but it may also have a two-stage configuration with upper and lower portions having appropriate intervals as shown in FIG.

A check sensor 17 can be attached to the inner surface of the inner bag 14. The check sensor 17 detects and displays the storage state of the grains contained in the inner bag 14. The check sensor 17 is an oxygen absorption sensor made of granules that detects the oxygen absorption and displays the discoloration degree. Is used. The check sensor 17 is housed together with an oxygen scavenger 29 in a breathable transparent plastic pouch 28, and is attached inside the inner pouch 14 with an adhesive 30 at a position facing the outer pouch mouth. The pouch 28 can be opened and closed by a chuck 31, so that the check sensor 17 and the oxygen absorber 29 can be replaced. In this way, the discolored state of the check sensor 17 contained in the pouch 28 can be inspected from the outside of the inner bag 14.

In such a grain bag, the inner bag 14 is inserted into the outer bag 7 (FIG. 1), and the joint edges 11 and 25 of the inner bag 14 are placed along the left and right ends of the outer bag 7, the bag bottom 4, and the like. Then, the inner bag mouth portion 12 is projected outward from the outer bag mouth so that the grains can be stored with the chuck 13 fully opened. The brown rice is set to fill up with about 30 kilograms. The inner bag 14 is limited to the circumference of the outer bag 7 and causes wrinkles. However, when the inner bag 14 is filled with the grains, the inner bag 14 expands and presses the outer bag 7 from the inside. Can receive some of the grain pressure.

When the inner bag 14 is filled with grains, the zipper 13 of the inner bag mouth portion 12 can be manually pressed from the front and back surfaces to fit the concave stripes 26 and the convex stripes 27 to close them. it can. At this time, the check sensor 17 is attached to the predetermined position in the inner bag 14 so that the air in the inner bag mouth 12 is pushed out as much as possible. In this state, the zipper sheet 16 is folded or wound in a three-fold or four-fold state on the bag front surface 9 side or the bag back surface 10 side for each height (A in FIG. 6).

When the inner bag mouth portion 12 is sealed in this manner, the inner bag mouth portion 12 comes close to the bag mouth of the outer bag mouth portion 3, and thus the folded inner bag mouth portion 12 is placed on the grain layer filled with the grains. The slide fastener 2 of the outer bag mouth portion 3 is closed by pressing it against the side surface portion (FIG. 6B) so that it is sandwiched between the inner bag 14 and the outer bag mouth portion 3 (FIG. 6C).

When inspecting the check sensor 17 during storage and storage of grain bags, if the slide fastener 2 of the outer bag 7 is opened, the inner bag mouth 12 remains folded and closed, and the position of the check sensor 17 is changed. Since it faces the outer bag mouth side, it can be seen through the transparent inner bag 14 (FIG. 6B). After the check sensor 17 is inspected, the slide fastener 2 is closed again to continue grain storage.

When the grains are discharged from the grain bag, the outer bag mouth is opened by the slide fastener 2, the inner bag mouth portion 6 is unfolded, and the outer bag mouth is pulled upward. It can be discharged by opening the zipper 13 of the inner bag mouth 12, holding the handle 5 of the outer bag mouth 3 and the handle 6 of the bag bottom 4 and lifting the bag bottom (FIG. 6D).

When transporting or handling a grain bag, the handles 5 provided on the front and back surfaces 9 and 10 of the outer bag mouth part 3, the handles 6 on the bag bottom part 4, and the like are gripped. At this time, since the grain pressure of the inner bag 14 always works on the outer bag 7, even if the outer bag 7 is handled and moved by the handles 5 and 6, a double bag form of the inner bag 14 and the outer bag 7 is formed. Has strong integration and can be handled stably. Further, the inner bag 14 and the outer bag 7 are less likely to be displaced from each other and have less friction, and the inner bag is less damaged.
