。Conventional paper containers, for example, paper containers used to hold snacks such as French fries, are made by first coloring one side of the container material, such as pure white kraft paper, using a printing means, and then stamping it by stamping. A container body 1 as shown in FIG. 1 is shaped, creases 2 and 3 for bending shown by dashed lines are made at key points of the body at the same time as the punching process, and glue allowances 4a, 4b, the front leaf part 5a, 5b and the rear leaf part 6 having the cut edge part are shaped, and then starch paste is applied to the glue margin parts 4a, 4b to form the front leaf part 6 as shown in FIGS. 2 and 3. Fold 2 in the order of 5a and 5b,
A substantially funnel-shaped container 7 is obtained by pressurizing the folded glue portion from 3, and in use, by pushing both ends of the flat container 7 inwardly, as shown in FIG. 4. It was made into a bag and contained 8 snacks.

口させる作業が面倒であるという欠点があった。However, in such conventional paper containers, printing pattern deviations tend to occur at the joint portion 5c (Fig. 2), which is the front side of the container, due to bending of the container material when it is inserted into the processing machine during the punching process. In addition, pure white kraft paper without an oil-resistant coating, such as a polyethylene coating, is used, so depending on the product placed inside the container, oil may seep into the container, causing oil stains and making the purchaser feel unclean. Because starch glue is used in the container, mold is likely to form, and the use of preservatives poses food hygiene problems.Furthermore, container manufacturing is troublesome and takes time to dry, and if the glue oozes out on the inside, When it polymerized, it became stuck and integrated with other containers, resulting in the so-called accordion phenomenon, and when it was separated, marks were left on the surface of the container, reducing the yield of the product, and the work of opening it when used as a bag was troublesome. There was a drawback.

容器を提供するものである。This invention aims to eliminate the above-mentioned drawbacks, and its feature is that a thermoplastic resin film such as polyethylene is coated (extruded) on one side of a mount made of paperboard, high-quality paper, or pure white kraft paper. ) or laminated (pasted) processed paper, the container body that forms the front and back paper leaves of the container is shaped by die-cutting, and the common edges of the front and back paper leaves are bent. The bending causes the resin film surfaces to face each other,
To provide a three-dimensional bag-like container that has good processability and good moisture resistance and leakage resistance by heating and pressing the side edges that coincide with the bending from directions orthogonal to each other to fuse the resin film. It is.

以下この考案を図に示す一実施例について詳述する。An embodiment of this invention shown in the drawings will be described in detail below.

形戒する。The container of this invention is constructed by applying a thermoplastic resin film 12 such as polyethylene to one surface of a mount 11 made of paperboard, high-quality paper, pure white kraft paper, etc. by known means (for example, extrusion coating, pasting, etc.) as shown in FIGS. 5a and 5l). As shown in FIG. 5, processed paper 13 (not shown), which has been colored (not shown) by printing or other methods, is placed parallel to the left side of the bending line 14 as a trapezoid. A container element consisting of a front sheet 15 having one side curved inward, and a rear sheet 16 having the same trapezoidal shape up to one side as the front sheet and one side extending outward with an arc. The body 17 is shaped by punching.

或する。Next, as an example, as shown in FIGS. 6a and 6l), a substantially L-shaped male heating plate 19 corresponding to two connected sides as a trapezoid with a heating source such as a sheathed heater 18 embedded therein is used. As shown in FIG. 7, using a manual heat sealing device 22 attached to a pressing frame 21 hingedly mounted on a base plate 20, the container is attached to the folding line 14 so that the thermoplastic resin film surfaces face each other. The element body 17 is bent so that the resin film surfaces face each other, and the two matched peripheral edges of the front and rear paper sheets forming a trapezoid are locally placed between the base plate 20 and the heating plate 19 attached to the pressing frame 21. As shown in FIGS. 8 and 9, the thermoplastic resin film on the opposing surface is melted to form a fused portion 23a by heating the paper sheets. The long side A of the two free sides of the processed paper 13 is first integrated with the welding part 23a, and then the short side B corresponding to the bottom side is integrated with the processed paper 13.
10 in the direction perpendicular to the plane of the short side B, and heat-seal the inner surfaces of the short sides B together in the same manner as described above, and integrate them at the fused portion 23b to form a bag-like shape. Shape the container 24.

収容することができる。As shown in FIG. 10, in this container 24, the vertical center line L of the non-parallel sides forming the trapezoid is extended outward in advance, so that the space between both sides 25 and 26 opens outward as a whole. , an arcuate side 26 that has a substantially truncated conical shape and is curved outward.
A paper piece 27 is formed from the fusion of both sheets to the folded part, and since the container has a three-dimensional opening in advance, it can be used for snacks such as fried potatoes as in the conventional container, as shown in Fig. 11. 28 can be stored in the container 24 very easily without touching them.

るので、軽食類を入れ易い等の効果を有する。As mentioned above, this invention constructs the bag body using processed paper that is coated with a synthetic resin film that can be fused and bonded to itself when subjected to conventional heat sealing or ultrasonic sealing, for example. A three-dimensional bag-shaped container is formed by placing the resin film shapes or surfaces facing each other and locally fusing the resin films together by heating and pressurizing them in two directions perpendicular to each other at the peripheral edge of the container. Because of this, there is no need to glue the joints of the bag-like container at certain joints, and the bag does not open as a result of the glue coming out like in the past, and when it is overlapped with another container, the space becomes integrated and an accordion phenomenon occurs. It is possible to produce with a high yield without any inconveniences in manufacturing technology such as Because it is coated with plastic resin, oil stains caused by snacks placed inside the container do not appear on the surface of the container, so it does not give the purchaser a feeling of uncleanliness. Since patterns such as colors and patterns printed on the container do not shift, productivity is improved and the container can be provided at low cost.Also, since it is pre-shaped as a hollow three-dimensional container, it has the advantage of making it easy to store snacks.
