Description

  In this device, when various cooked foods are displayed and sold in a refrigerated or frozen state, for example, at a convenience store, a supermarket, etc., and then purchased by a purchaser, for example, in a microwave oven, the food is transferred as it is. It can be easily cooked and heated in a microwave oven, and even if it is hot immediately after heating, it can be safely held by hand, making it easy to eat directly from the container. The present invention relates to a paper container for food storage and heating.

  Conventionally, various box-shaped food containers have been proposed, which are mainly made of paper materials that have heat resistance, water resistance, etc. and are packaged so that they can be heated by microwave oven equipment. 1 is a paperboard container according to No. 1, and a food storage and cooking paper container according to Patent Document 2. As schematically shown in FIG. 5, the paperboard container of Patent Document 1 has a triangular shape by connecting front and rear, left and right peripheral walls to each side of the bottom of the quadrilateral shape and bending between adjacent peripheral walls. A folding piece 103 that is superimposed on the shape and bonded to, for example, the outer side surfaces of the left and right walls 102 is continuously formed, and a pair of lid pieces 104 that are connected to each other are connected to the upper edges of the front and rear walls 101. As shown in FIG. 6, the paper container according to Patent Document 2 includes a handle portion 105 provided continuously from the left and right walls 102 in a folded piece 103 bonded to the left and right walls 102 in the paperboard container shown in FIG. 5. The left and right walls 102 and the folding piece 103 are fixed by inserting the provided cutting piece 106.

JP 2000-238748 A JP 2008-68885 A

  However, in the paperboard container according to Patent Document 1, when the left and right walls 102 to which the folded pieces 103 are bonded are pushed with fingers or the like from outside as shown in FIG. Since the inner side surfaces 103 are not joined to each other, the left and right walls 102 bend inward of the container. For example, when the container itself is lifted by being sandwiched from the left and right by fingers, the left and right walls 102 to which the folded piece 103 is bonded bend inwardly, and the peripheral wall of the container itself expands toward the top. Even if it is easy to lift by being formed, the container may slide off from the fingers due to the weight of the contents and the smoothing process of the outer surface of the container. Moreover, for example, when the food contents are heated in a container to be heated by a microwave oven, the container itself becomes very hot and it is difficult to make direct contact with fingers, so it is sufficient when it is in a heated state. It is equally troublesome because you have to wait for it to cool.

  Further, in the food container according to Patent Document 2, the inward bending of the left and right walls 102 as in Patent Document 1 is prevented by being fixed by inserting the cut piece 106 into the folded piece 103. However, since it is necessary to insert the cut piece 106 provided continuously from the left and right walls 102 into the folded piece 103 and to engage with each other, the assembly is troublesome. Further, when the container itself is lifted or the like, even if it can be lifted by a handle 105 formed on the upper edges of the left and right walls 102 in a folded shape outside the container, the width of the handle 105 protruding to the outside of the container Since it is not large, it is heated by water vapor ejected by microwave heating and cannot be held by the handle portion 105 unless it is sufficiently cooled. Not only that, but because the handle 105 travels to the side, the handle 105 becomes a hindrance when packaging to store and sell food, and when displaying it side by side. It will be a thing.

  In addition, the present inventor puts 200 cc of water in an actual microwave apparatus, for example, in the container of Patent Document 1 or 2, and heats the container for 3 minutes with a microwave apparatus having an output of 1000 W. When the temperature of the outer side surface was measured, it was about 85 ° C. on the outer side surface of the front and rear wall portions and 50 to 73 ° C. on the outer side surface of the triangular folded piece portion. In such a high temperature state, it was dangerous to directly touch it with fingers, and it was obvious that it would cause burns if touched.

  Therefore, the present invention has been devised in view of the conventional circumstances as described above, and its purpose is to form a box with a lid capable of storing various foods by a sheet-like paperboard material of a predetermined thickness. When the food stored in the container is heated by the microwave oven while being stored in the container, even if the surrounding wall is heated immediately after the heating, the food is lifted by a knob formed away from the surrounding wall. It can be handled safely without incurring burns, etc., and even if an external force is applied from any direction of the surrounding wall, it will not bend inward of the container, and it will be easy to handle. Another object is to provide a paper container for food storage and heating.

In order to solve the above-described problems, in the present invention, description will be given with reference numerals in the form for carrying out the later-described invention. 4, left and right wall portions 3, 5 are connected in a staircase shape, and externally foldable in a triangular shape arranged by connecting the adjacent wall portions 2, 3, 4, 5 to each other. The folding pieces 6, 7, 8, 9 are one of the folding parts of the outer folding pieces 6, 7, 8, 9 on the outer surface of one of the walls (3, 5) facing each other. In a paper container formed by adhering by folding inner adhesive pieces 6a, 7a, 8a, 9a and closing an opening by a cover piece 15 continuously provided from opposing wall parts 2, 4 or 3, 5 The other folding part of the external folding pieces 6, 7, 8, 9 bonded to the outer surface of the part (3, 5) A knitted piece 10 extending outward of the container main body is provided on a foldable outer piece 6b, 7b, 8b, 9b so that it can be folded back or the outer foldable pieces 6, 7, 8, 9 are not adhered. Either one of the wall portions (3, 3) facing each other by bonding the outer folding pieces 6, 7, 8, 9 to the other wall portion (2, 4) facing each other. 5) The cover piece 15 which is provided continuously from the cover and covers the opening is covered, and the fold is folded inward of the container so that one edge is in contact with the inner side surface of any one of the wall portions (3, 5). It is characterized in that the regulating piece 14 is continuously provided.
Further, the external folding pieces 6, 7, 8, 9 may be bonded to the front and rear wall portions 2, 4 without being bonded to the outer side surfaces of the left and right wall portions 3, 5, The lid piece 15 is connected to the front and rear wall portions 2 and 4, and the folding restriction piece 14 is connected to the left and right wall portions 3 and 5, respectively. In short, the external folding pieces 6, 7, 8, and 9 are bonded. The left and right wall portions 3 and 5 where the lid 15 is not bonded to the front and rear wall portions 2 and 4 or the left and right wall portions 3 and 5 facing each other, and the external folding pieces 6, 7, 8 and 9 are not bonded. Alternatively, the folding restriction piece 14 is continuously provided on the front and rear wall portions 2 and 4.
The knob 10 is at least paired with the folded outer pieces 7b, 9b or 6b, 8b of the outer folded pieces 6, 7, 8, 9 arranged symmetrically with respect to the center position of the container. It can be configured by being formed.
Further, the knob piece 10 has one wall portion 2 that faces the tip portion of the folded outer piece portions 6b, 7b, 8b, and 9b where the outer folded pieces 6, 7, 8, and 9 are connected. , 4 or 3, 5 passes through the upper end position of the side edge that is the boundary with the other wall 3, 5, 2, 4, respectively, and reaches the boundary with the folded inner adhesive piece 6 a, 7 a, 8 a, 9 a. It can be configured by being formed as an area that is bent outward by the folding line 11.
The lid piece 15 can be configured to have a notch-shaped engagement portion 16 that is engaged with each other at approximately the middle position of the opening of the container itself at a substantially central position of the tip edge.

In the paper container for food storage and heating according to the present invention configured as described above, the predetermined food F stored in the container can be heated by the heat treatment by the microwave device while being stored in the container. After the heating, the container 10 is lifted and removed without being affected by the heat of the container itself heated by gripping the knob 10 extending outward from the container. By keeping the shape of the container, it is not distorted by an external pressing action, and the container shape is maintained.
The knob 10 is formed to be folded at the tip of the folded outer piece 6b, 7b, 8b, 9b of the outer folded piece 6, 7, 8, 9 so as to extend outward from the main body portion of the container itself. Thus, even if the container is heated to a high temperature, it is not affected by the heat, and can be lifted safely by allowing gripping with fingers.
The outer folding pieces 6, 7, 8, and 9 have either one of the opposing wall portions 3, 5 or 2, 4 to which the outer folding pieces are bonded, and the other opposing wall portion 2, 4 or 3, 5 By arranging the container inward, the container can be shaped and not distorted against the pressing action from the outside of the other wall 2, 4, or 3, 5.
Further, the folding restriction piece 14 is folded inward from the upper edge of the other opposing wall portion 2, 4 or 3, 5 where the external folding pieces 6, 7, 8, 9 are not bonded. By being provided in a row, the container is shaped inside the opposing wall 3, 5, or 2, 4 and one of the outer foldable pieces 6, 7, 8, 9 is bonded. The container shape is maintained without being bent even by the pressing action from the outside of the wall portions 3, 5 or 2, 4 facing each other.

  Since this device is configured as described above, food F stored in a container can be heated by a microwave oven in a box-shaped container with a lid formed of a sheet-like material. Even if the wall portions 2, 3, 4, and 5 that are surrounded by heat are heated, they are lifted by the knob 10 without directly touching these wall portions 2, 3, 4, and 5, for example, in the microwave oven The container itself can be bent inward by an external pressing force, for example, a pressing action sandwiched by fingers, in any of the wall portions 2, 3, 4 and 5. It can be easily handled by maintaining its outer shape.

  That is, in this device, in the present invention, the other of the external folding pieces 6, 7, 8, 9 bonded to the outer surface of any one of the opposing wall portions (3, 5) that surrounds the bottom wall portion 1 This is because the knob 10 extending outward from the container body is provided on the folded outer piece 6b, 7b, 8b, 9b, which is a folded portion of the outer folding piece 6, and the outer folded pieces 6, 7, Any one of the above-mentioned ones where the outer folding pieces 6, 7, 8, 9 are bonded to either one of the other wall portions (2, 4) facing each other without being bonded A cover piece 15 that is continuously provided from one wall portion (3, 5) and covers the opening is covered, and the container is arranged so that one edge abuts against the inner surface of either one of the wall portions (3, 5). This is because the folding restriction piece 14 that is folded inward is provided continuously.

  The knob 10 is folded in half to be bonded to the outer surface of one of the opposing wall portions 3, 5 or 2, 4 that surrounds the bottom wall portion 1 in a standing manner. By folding the front end portions of the folded outer pieces 6b, 7b, 8b, 9b in the tatami pieces 6, 7, 8, 9 in a folded shape, it is formed to extend outward from the main body portion of the container itself. Therefore, by heating the food F together with the container with a microwave oven, even if the container itself is heated, the knob 10 itself is not heated and can be easily grasped with fingers. Therefore, it is possible to lift the container without directly touching the main body of the container as in the past, and even a container that is hot immediately after heating can be handled safely, and burns etc. Absent. Incidentally, when 200 cc of water is put in a container and heated with a microwave oven having a capacity of 1000 W, the walls 2, 3, 4 and 5 are 85 ° C., and the external folding pieces 6, 7, 8, and 9 themselves are 65. Even at a temperature of 50 ° C., the pick piece 10 had a temperature of 50 ° C. or less, and there was no problem in touching it directly with fingers.

  Further, the folding restricting piece 14 is formed continuously from each of the other wall portions (2, 4) facing each other without being bonded to the outer folding pieces 6, 7, 8, 9; The outer foldable pieces 6, 7, 8, 9 are adhered to each other and covered with a cover piece 15 which is continuously provided from any one of the wall portions (3, 5) facing each other and covers the opening. Since it is formed so as to be folded inward of the container so that one edge abuts against the inner side surface of one wall portion (3, 5), this one wall portion (3, 5) is pressed from the outside. Even if the action is loaded, the wall portions (3, 5) are not bent inward of the container, and the outer shape of the container can be maintained as it is. Moreover, since the folding restricting piece 14 is simply connected so as to be folded inward from the wall (2, 4), it is structurally simple, easy to assemble, and troublesome. Absent. Therefore, the wall portion (2, 4) where the external folding pieces 6, 7, 8, 9 are not bonded is the wall portion (where the external folding pieces 6, 7, 8, 9 are bonded). 3) and 5), the outer shape of the entire container is maintained, so that the walls 2, 3, 4, and 5 can be applied by applying external force from four directions. The container itself can be easily handled without bending inward of the container.

  In addition, the code | symbol attached | subjected in each of the means for solving said subject, and the item of the effect of an invention was attached | subjected in order to make easy reference with the part which shows each structure part described in drawing. The present invention is not limited to the structure and shape shown by these descriptions and reference numerals in the drawings.

It is a perspective view at the time of opening similarly a paper container. It is a development view of the container base paper. Similarly, it is a perspective view when opening at the time of eating, for example. Similarly, in the conventional example, it is a perspective view when an external force is applied when the paper container is opened. Similarly, in another example of the conventional example, it is a perspective view of a container reinforced so as to prevent bending of the folded piece portion toward the inside of the container.

  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the figure is a bottom wall portion having a substantially rectangular shape in a plane, and 4 is a periphery of the bottom wall portion 1. The front and rear wall portions 2 and 4 and the left and right wall portions 3 and 5 are connected to the side positions through folding lines formed between the bottom wall portion 1 and the periphery so as to surround the periphery. The front wall portion 2, the left wall portion 3, the rear wall portion 4, and the right wall portion 5 that are adjacent to each other are folded and joined to each other. A total of four external folding pieces 6, 7, 8, and 9 that are bonded to each other are connected. Each of the front and rear wall portions 2 and 4 and the left and right wall portions 3 and 5 has an inverted trapezoidal shape that gradually becomes wider from the bottom wall portion 1 to the opening portion, and rises in the form of a leg around the bottom wall portion 1. It is configured as an inverted trapezoidal box container having a large opening on the front and rear wall portions 2 and 4 and left and right wall portions 3 and 5, and a lid piece 15 to be described later is provided continuously from the wall portions (3 and 5). The opening is closed.

  That is, the front wall portion 2, the left wall portion 3, and the rear wall around the four sides of the front, rear, left and right sides of the bottom wall portion 1 disposed at the center as shown in FIG. 3 so as to be configured as a box-shaped paper container. The part 4 and the right wall part 5 are connected to each other, and external foldable pieces 6 are connected to each other between the wall parts 2,. These are continuous from the upper edge of the wall portion 2,... And formed integrally with an appropriately thick sheet-like material that has been subjected to a predetermined treatment so that at least the inner surface has oil resistance, water resistance, etc. Has been. This sheet-like material has a paperboard material, a heat-resistant plastic film material that is not damaged even when heated by a microwave oven device, a laminated material of paper and plastic film, a laminate treatment material, and an intermediate layer with a gap 3 It is formed of a layered laminated material or the like, and is formed of a material that can be heated by a microwave oven device suitable for storing various foods F.

  The external folding pieces 6, 7, 8, and 9 are configured such that the side sides in the circumferential direction of the wall portions 2, 3, 4, and 5 are close to each other between the adjacent wall portions 2, 3, 4, and 5, respectively. The folding inner adhesive strips 6a, 7a, 8a, which are half-folded triangular strips, are formed by central folding lines formed on the outer folding strips 6, 7, 8, 9 themselves starting from the bottom wall 1 side. , 9a and the folded outer piece 6b, 7b, 8b, 9b. And the folding inner side adhesive piece part 6a, 7a, 8a, 9a which is one folding part which is a half-folded triangular piece part, and the folding outer piece part 6b, 7b, 8b which is the other folding part , 9b are folded in two outside the container by overlapping each other, and the folded outer folded pieces 6, 7, 8, 9 themselves are, for example, one of the folded portions on the left and right wall portions 3, 5 side. The outer side surface portions of the folded inner adhesive pieces 6a, 7a, 8a and 9a are bonded and fixed to the outer surfaces of the left and right wall portions 3 and 5 with an adhesive or the like to be assembled into a box shape.

  In addition, it adhere | attaches between the inner side surfaces of each folding inner side adhesive piece part 6a, 7a, 8a, 9a in each outer folding piece 6, 7, 8, 9 and folding outer piece part 6b, 7b, 8b, 9b. They are not in contact with each other but are in contact with each other so as to be separated from each other.

  Folding outer pieces 6b, 7b, which are the other folding parts of the half-folded triangular shape that are not directly bonded to the outer surfaces of the left and right wall parts 3, 5 in the outer folding pieces 6, 7, 8, 9 , 8b and 9b are formed by bending a knob 10 which extends outward of the paper container. As shown in the figure, the knob 10 has a pair of folded outer pieces 7b, 9b, or 6b that are paired at a symmetrical position on the front and rear or on the left and right of the plane centered on the center position of the bottom wall 1 in the paper container itself. , 8b are bent. The knob 10 shown in the figure has a front and rear wall to which the outer folding pieces 6, 7, 8, 9 are connected to the tip of the other folding outer piece 6b, 7b, 8b, 9b. Part 2, 4, ie, the upper end position of the side edge that is the boundary with the right wall part 5 in the front wall part 2, the upper end position of the side edge that is the boundary with the left wall part 3 in the rear wall part 4, respectively, Is formed as an area that is folded outward by a fold line 11 that reaches the boundary with the folded inner adhesive piece portions 6a, 7a, 8a, and 9a.

  This knob 10 is a protrusion located above the upper edge position of the folded inner adhesive pieces 6a, 7a, 8a, 9a so as to extend slightly above the container itself so that it can be easily grasped by fingers. The part has, for example, an upper edge of a mountain shape or a triangle shape, and is different in appearance from the folded inner adhesive piece portions 6a, 7a, 8a, 9a. The knob 10 itself is preferably folded back by the folding line 11 so as to extend outward from the container, and is preferably separated as much as possible from the main body part of the container itself. The container main body portion that is heated to a high temperature is not affected by heat and can be gripped by fingers.

  Further, each of the wall portions where the external folding pieces 6, 7, 8, 9 are bonded and confronting each other, in the drawing, each of the left and right wall portions 3, 5 closes the opening of the container itself. A pair of lid pieces 15 that mesh with each other are continuously provided. The lid piece 15 has, for example, a notch-shaped engagement portion 16 that is engaged with each other at approximately the middle position of the opening portion of the container itself at the substantially center position of the distal end edge, and the opening portion is engaged by the engagement of the engagement portion 16. Can be closed from the left and right.
