  The packaging bag for water-retained foods such as patent document 1 is effective in eliminating the stickiness in the bag by releasing water vapor generated when the water-retained food such as grilled rice balls and hamburgers are overheated. As a container for storing an object to be stored such as a bread or a donut, there is a problem that the storing and taking out of the container is troublesome and the appearance at the time of display of the contents stored in the container is poor.

  The hamburger bag described in Non-Patent Document 1 has a hollow inverted conical shape, so that it is easy to store and take out the objects to be contained, but it accommodates objects to be contained such as hamburgers, donuts and breads. In this case, there is a problem that the container is tilted on the mounting plane so that it easily rolls, and the appearance of the contents in the container is extremely poor.

  The paper packaging bag described in Non-Patent Document 2 can be easily accommodated when accommodating objects such as hamburgers, donuts, or bread, but there are many parts and bonding locations that form the packaging container, and the cost is high. Since the width of the heat seal portion between the side member and the upper and lower side members that are bulky and “town” is very narrow, it is easy to tear when containing the contained object, and its accommodation and removal are troublesome. There is a problem that the appearance at the time of display is poor, and there are a plurality of flaps on the opening side, and since these overlap each other, there is a problem that it is difficult to eat the opening contents.

  The present invention facilitates the storage and removal of the contents to and from the paper packaging container for accommodating the contents such as hamburger, donut or bread, and makes the container opening side difficult to break. The purpose is to improve the appearance of the display.

  The object of the present invention is to heat a square composite paper uniformly coated with a heat-adhesive resin from the fold line with the resin-coated surface on the inside, and have both sides on the inside on the hypotenuse toward the fold line. This can be achieved by adhering except the upper side edge at the seal part.

  The long side of the two sides parallel to the heat seal portion coincides with the position of the folding line, the vertical side perpendicular to the two sides coincides with the side edge, and the parallel of the heat seal portion 6 Of the two sides, the long side is about twice the short side and the vertical side is about three times the length of the short side, and the long side is about twice the short side and the vertical side is short. It is also possible to set the length to about 5.5 times the length, and further, the length of the long side is about 5 times the short side and the vertical side is about twice the length of the short side. The problem related to was solved.

Since the present invention employs the above-described means, the following effects can be obtained.
The paper packaging container according to the present invention is a paper packaging container according to claim 1, wherein a rectangular composite paper uniformly coated with a heat-adhesive resin is folded back from the fold line with the resin-coated surface inside, and both side edges thereof are folded. Because the heat seal part with the hypotenuse toward the inside is bonded except for the upper part of the side edge, the product can be produced by simply folding the square composite paper in two and bonding the two left and right parts at the heat seal part. Because it can be provided at low cost, and when it is desired to accommodate an object such as a hamburger or a donut, the opening side can be easily expanded by the above-mentioned oblique side, and the center of the bottom side can be partially flattened. It can be placed and does not fall down diagonally, it can improve the appearance of the contents in the container when it is displayed, and the heat seal short side part has a width, so that the heat seal part is difficult to break when accommodating the contents , There is an excellent effect that can be used safely.

  According to the invention of claim 2 in the present invention, in addition to the above effects, the finger edge is formed by folding the composite paper by slightly shifting the opening edge of the paper packaging container. Since it is easy to pick and spread with fingers, it is possible to add the effect that it is very convenient for use in stores, and the long side of the two sides parallel in the vertical direction is folded as in the third aspect of the present invention. If the shape matches the line position and the vertical sides perpendicular to these two sides coincide with the folded side edges, there will be no unnecessary protrusions on the outside of the heat seal part, and the paper packaging will look even better. The effect of becoming a container could be added.

  In addition, as in claim 4 of the present invention, the heat seal portion is configured such that, of two parallel sides, the long side is about twice the length of the short side and the vertical side is about three times the length of the short side. If it is long, it is easy to obtain a deep dish-like paper packaging container, and it is easy to put in a container that is not so large, such as deep-fried food. The effect that the object can be seen more easily can be added. Further, as in claim 5 of the present invention, the heat seal portion has a long side length of about 5 times the short side of the two parallel sides and a vertical side. If it is about twice the length of the short side, a shallow dish-shaped paper packaging container can be obtained easily, so that the items to be stored can be laid sideways, and the heat seal part If you hold it and pull it to the outside, the open side will narrow and the lying containment will be vertical, and the purchaser will eat the containment. It was able to add the effect of Kunar.

  Further, as in claim 6 of the present invention, the heat seal portion is formed such that the long side of the two parallel sides is about twice the length of the short side, and the vertical side perpendicular to the two parallel sides is the short side. By making it about 5 times the length, a teacup-shaped paper packaging container can be easily obtained, and when storing slender objects such as sausages and potato chips, it is easy to put inside the container, Since the range is high up to the vicinity of the opening and the width is wide, it is possible to add an effect that the heat seal part is not easily broken when the object is accommodated, and the oblique side of the heat seal part is bent as in claim 7 of the present invention. Thus, the effect that various changes can be made to the shape of the side edge portion in the developed state can be added.

  As the best mode for carrying out the present invention, as shown in FIGS. 1 and 2, a square composite paper 1 uniformly coated with a heat-adhesive resin such as polyethylene is folded with the resin-coated surface 2 inside. Folded from the line 3 as shown in FIG. 3, both side edges 4 are substantially trapezoidal heat seal portions 6 having a hypotenuse 5 toward the fold line 3 except for the upper side edges as shown in FIG. 3. A paper packaging container according to the present invention as shown in FIG. 1 could be constructed by pressing and bonding with a tool.

  The long side 7A of the two sides parallel to the heat seal portion 6 coincides with the position of the fold line 3 as shown in FIG. 3, and the vertical side 7B perpendicular to these two sides is defined as the side edge 4. In addition, of the two parallel sides of the heat seal portion 6, the long side 7A is about twice as long as the short side 7C as shown in the development example chain line of FIG. 2, and the vertical side 7B is the length of the short side 7C. The long side 7A is about twice the short side 7C and the vertical side 7B is about 5.5 times the length of the short side 7C as shown in the development example chain line of FIG. In addition, the length of the long side 7A may be about 5 times the short side 7C and the vertical side 7B may be about twice the length of the short side 7C as shown in the development example chain line of FIG.

  As one example of the paper packaging container of the present invention, a heat-adhesive resin such as polyethylene having no problem in food hygiene is heated and deposited on one side of western paper or thatched Japanese paper, or a polyethylene thin film is laminated. A rectangular composite paper 1 having a size capable of wrapping an object to be accommodated such as a hamburger or a donut such as a so-called polylaminated paper is placed at a position where the edge on the opening side is slightly shifted back and forth with its resin-coated surface 2 as the inside. The folded line 3 is folded as shown in FIG.

  Next, in order to bond the folded side edges 4 except for the upper part thereof, a heat seal portion 6 having a hypotenuse 5 toward the fold line 3 is formed. In this case, as shown in FIG. This heating and melting is performed by partially melting the heat-adhesive resin by pressing the both side edges 4 except for the upper part by a heating and pressing jig corresponding to the heat seal part 6 except for the upper edge. Since the both side edges 4 can be bonded by the heat seal part 6 except for the upper part without using any special glue due to the cooling and solidification welding force of the resin later, the composite paper 1 is accommodated in the lower part of the both side edge parts. An object storage portion 8 can be formed, and a deep dish-like paper packaging container in which two flaps 9 connected to the storage portion 8 are formed on two opening sides 8A connected to the storage portion 8 can be obtained. It was.

  When opening the opening side 8A, in order to facilitate opening, it is preferable that one of the end sides of the opening side 8A is shifted from the other by about 5 mm as shown in FIG. When the short side of the paper 1 was 135 mm, the length of the short side 7C was about 10 mm.

  The paper container of the present invention is configured as described above, and in its use, a deep dish-shaped paper packaging container having a standard shape as shown in FIG. 1 is taken as an example in the paper packaging container. A case where an object to be stored such as a hamburger, a donut, or a bread is stored will be described.

  First, if a paper packaging container folded in a flat state as shown in FIG. 3 is used to spread the opening side 8A with fingers by using the finger hooking portion 10 provided on the opening side 8A of the container as shown in FIG. It becomes a deep dish-like paper packaging container shaped like a ship.

  When a customer wants to eat a contained item such as a hamburger, donut or bread immediately after selling individually, after widening the opening side 8A as described above, the heat seal parts 6 on both sides are picked with fingers. It is arranged in a dish shape, and a container such as a hamburger, donut or bread is accommodated in a paper packaging container having an open side and handed to a customer.

  When exhibiting in a showcase for sale, the open side 8A is widened back and forth so that customers can see the hamburger, donuts and bread on the paper packaging container. It is stored in a flat paper packaging container in a horizontal state, that is, in a lying state, and placed in a display tray in a flat state to be displayed at the store.

  When selling items to be contained such as potato chips, donuts or sausages in this paper packaging container, if you hold the heat seal 6 on both sides with your fingers and push them inward, the opening side 8A will be narrowed and made of paper. The to-be-accommodated objects AT such as potato chips, donuts and sausages in the packaging container can be accommodated in an upright state, and can be sold by lightly wrapping the to-be-contained objects in the entire paper packaging container including the flap 9.

  When eating the contents to be contained in the paper packaging container, the contents are exposed from the paper packaging container by folding the flaps 9 formed on the opening side 8A of the paper packaging container to the outside in this state. You can eat.
