By laminating them together, the degree of adhesion, independence, etc. of the air inlet is increased, and leakage after filling with stored items is completely prevented.

が広く開発されている。Conventional technology An air inlet made of a cylindrical body made of a strong material suitable for the width of the bag bottom is constructed in one corner of the bag with a square bottom, and items are stored in the bag through this air inlet.
Multilayer paper bags whose inlet opening is folded inward to seal the bag have been widely developed.

発された全く新規な技術に関するものである。Problems to be Solved by the Invention However, the bags of this type that have been widely developed in the past are generally constructed of highly tough materials. As a result, the inlet loses its flexibility, and on the contrary, the effective action of the original non-return valve is significantly reduced. As a result, after the contents were filled, the bottom of the inlet did not come into complete contact with the inside of the upper part of the inlet due to the internal pressure of the bag, resulting in a defect in which the contents leaked from the gap between the bottom and the inside of the upper part. The present invention relates to a completely new technique developed in view of these conventional problems.

に防止させる多層紙袋に係る。Means and Effects for Solving the Problems The present invention, which solves the above-mentioned problems, uses a thin synthetic resin film cylinder on the cylindrical body that constitutes the inlet of a multilayer paper bag, and a reinforcing material is pasted only on the upper side of the thin film cylinder. The present invention relates to a multilayer paper bag in which, after the stored items are stored, the bottom of the inlet port is polymerized and tightly adhered to the inside of the upper part of the bag due to the internal pressure of the bag, thereby completely preventing leakage of the stored items.

7, etc., and then make second fold lines 8, 9, 10, 1 at intervals of 1/2 of the bottom width from the first fold line.
A thin synthetic resin film cylinder 12 made of polyolefin is glued and placed on the triangular folded piece, for example, number 5 (see Figure 2) at one corner of the triangular folded piece, and then A reinforcing material 13 made of paper, woven cloth, etc., which has a width between the second fold line or larger and is the same as or slightly longer than the length of the thin film tube, is attached to the synthetic resin thin film tube 1.
After attaching the triangular folded piece 2 and the non-adhered cylinder wall surface so as to cover each other, fold each side wall inward from the second fold line according to a conventional method to form the folded piece 14,
Glue is attached to the necessary locations such as 15, 16, 17, etc. to make the multilayer paper bag of the present invention.

る。Function The inlet of the multilayer paper bag of the present invention is composed of a flexible synthetic resin thin film cylinder, so after filling the bag with the contents by inserting the nozzle of the filling machine into the synthetic resin thin film cylinder, , when the nozzle is pulled out and the bottom of the inlet comes close to the inside of the top due to the internal pressure of the bag,
Utilizing its flexibility, the inlet has an increased degree of adhesion at the bottom compared to the inlet of multilayer paper bags that have been widely used in the past. Furthermore, a reinforcing material is provided that covers the entire wall surface of the cylinder on the side that is not bonded to the triangular folded piece of the synthetic resin thin film tube that makes up the inlet, so the inlet cannot stand alone with just the synthetic resin thin film tube. This reinforcing effect allows the air inlet to be neatly shaped.

層紙袋を提供するものである。Effects The present invention significantly improves the degree of adhesion, independence, etc. compared to the inlet configuration of multilayer paper bags that has been widely developed in the past. Moreover, since bags can be made with a simple structure of the blowing port, work efficiency is significantly improved. Therefore, the present invention provides a multilayer paper bag that has great practical value, such as having the effect of completely preventing the leakage of stored items from the blowing port, easily improving the efficiency of filling operations, and facilitating cargo handling operations. It is.
