  FIG. 3 shows an exploded perspective view of the packaging bag 2. The packaging bag 2 is composed of a flat pouch with a four-side seal, and is formed by laminated films 3, 4, and 5 of soft resin films. A laminated film 5 is disposed on the back surface of the packaging bag 2, and laminated films 3 and 4 are disposed on the front surface. In addition, although one surface in the front-rear direction of the composite container 1 is referred to as a front surface and the other surface is referred to as a back surface, the same is true even if the front surface and the back surface are interchanged.

  The upper end portion of the laminated film 3 and the lower end portion of the laminated film 4 are bent forward and fixed to each other by the heat welding portion 2 c to form the wing portion 11. The lower end portion and both end portions of the laminated film 3 are directly fixed to the peripheral portion of the laminated film 5 by the thermal bonding portion 2a. The upper end portion and both end portions of the laminated film 4 are directly fixed to the peripheral portion of the laminated film 5 by the thermal bonding portion 2b.

  As a result, the packaging bag 2 is sealed by forming a storage space 8 (see FIG. 2) in which the contents N are stored, and a wing portion 11 projects from the front surface of the packaging bag 2. When the packaging bag 2 is manufactured, one side is opened and the peripheral portion is fixed by the heat bonding portions 2a and 2b, and after the contents N are charged, one side is fixed.

  FIG. 4 shows a side sectional view of the laminated film 3. The laminated films 4 and 5 are also formed in the same manner as the laminated film 3. The laminated film 3 is formed by laminating a seal layer 3b and a base material layer 3c.

  As the seal layer 3b, one that is generally used as a food packaging material heated or cooked in a microwave oven can be used. Specifically, low-density polyethylene film, ultra-low-density polyethylene film, linear low-density polyethylene film, medium-density polyethylene film, high-density polyethylene film, unstretched polypropylene film, ethylene-vinyl acetate copolymer film, ethylene-acrylic An acid copolymer film, an ethylene-methacrylic acid copolymer film, an ethylene-methyl acrylate copolymer film, an ethylene-ethyl acrylate copolymer film, an ethylene-methyl methacrylate copolymer film, an ionomer film, or the like can be used.

  1 and 2, the packaging bag 2 is provided with notches 10 formed of notches for tearing the packaging bag 2 at both ends between the wing portion 11 protruding from the front surface and the exterior body 20. . The wing portion 11 is formed with isolation portions 6a and 6b that are isolated from the storage space 8 by the thermal bonding portion 2c.

  The isolation part 6a is provided in the central part in the left-right direction, and a steaming hole 7a made of a C-shaped cut through the laminated films 3 and 4 is formed. The isolation part 6b is provided on the left and right sides of the isolation part 6a via the communication part 11a, respectively, and a steam hole 7b made of an I-shaped cut through the laminated films 3 and 4 is formed. The communication part 11 a is formed in communication with the storage space 8.

  When the composite container 1 is heated by the microwave oven, the thermal bonding part 2c around the isolation parts 6a and 6b is peeled off due to the expansion of the packaging bag 2, and steamed through the steaming holes 7a and 7b. The steam holes 7a and 7b may be formed by through holes.

  FIG. 5 shows a development view of the exterior body 20. On the outer surface of the outer package 20 made of paperboard, a printing layer (not shown) of characters and designs indicating product names and contents is formed by printing. The exterior body 20 is adjacent to both sides of the front surface portion 20a that forms the front surface, with back surface portions 20b and 20c that form the back surface, via a bent portion 21 that includes a fold line. An adhesive margin 29 (indicated by cross hatching in the figure) is provided at the side end of one back surface portion 20c. Adhering both ends in the circumferential direction of the exterior body 20 with the adhesive allowance 29 forms a joining portion 27 in which the back surface portions 20b and 20c are overlapped to form the exterior body 20 in a cylindrical shape.

  The upper end of the front surface portion 20a is formed in a curved shape with the center portion disposed downward with respect to both ends in the left-right direction. Similarly, the upper ends of the back portions 20b and 20c are also formed in a curved shape with the center portion disposed downward with respect to both ends in the left-right direction on the back surface of the exterior body 20 in a state of being formed in a cylindrical shape. In addition, inclined portions 9 are provided at the left and right ends of the bottom portion of the front surface portion 20a so that the lower portion is inclined toward the center in the left-right direction. A similar inclined portion 9 is provided at the right end of the bottom portion of the back surface portion 20b and the left end of the bottom surface of the back surface portion 20c.

  Pushing portions 24 are provided on the pair of bent portions 21, respectively. The pushing portion 24 is formed by a fold line 22, a fold line 23, a slit 28a, and a slit 28b. The fold line 22 (first fold line) and the fold line 23 (second fold line) are formed so as to extend in the vertical direction with the folding portion 21 interposed therebetween. In addition, the folding line 22 and the folding line 23 are formed in a curved shape in which the upper and lower sides are inclined toward the outer side in the left-right direction (the direction of the bent part 21) with respect to the central part in the vertical direction. In the present embodiment, the fold line 22 and the fold line 23 are formed with the bent portion 21 as a symmetric line, but may be asymmetric if provided with the bent portion 21 interposed therebetween.

  The upper end of the fold line 22 and the upper end of the fold line 23 are connected by a slit 28a, and the lower end of the fold line 22 and the lower end of the fold line 23 are connected by a slit 28b. The slit 28a and the slit 28b are formed in a downward convex curve.

  A fold line 25 and a fold line 26 are provided at both ends of the lower slit 28b so as to extend obliquely to the lower end of the exterior body 20. The lower ends of the fold line 25 and the fold line 26 are connected to the lower end of the inclined portion 9.

  The slit 28 a may be omitted, and the upper end of the fold line 22 and the upper end of the fold line 23 may be connected by the upper end of the exterior body 20. Further, the slit 28 b, the fold line 25, and the fold line 26 may be omitted, and the lower end of the fold line 22 and the lower end of the fold line 23 may be connected by the lower end of the exterior body 20.

  In addition, the front portion 20a and the rear portions 20b and 20c are formed with an adhesive portion 40 that is fixed to the packaging bag 2 (see FIG. 2) by application of an adhesive. The adhesive part 40 is composed of a plurality of application parts 40a, 40b, and 40c in which an adhesive is applied linearly. The application parts 40a and 40b are formed to extend vertically, and the application part 40c is formed to extend in the left-right direction. The application part 40a is arranged on the inner surface of the center part on the front side and the back side of the cylindrical outer package 20. The application part 40b is each arrange | positioned at the both sides of the application part 40a. The heights of the lower ends of the adhesive portions 40a and 40b are different between the front surface portion 20a and the back surfaces 20b and 20c of the packaging bag 2, respectively. That is, the height of the lower ends of the bonding portions 40a and 40b of the front surface portion 20a is formed higher than the height of the lower ends of the bonding portions 40a and 40b of the back surface portion 20b. Thereby, the content N of the bottom part of the packaging bag 2 can be taken out more easily. In addition, you may make the height of the lower end of the adhesion parts 40a and 40b the same with the front surface part 20a and the back surfaces 20b and 20c.

  When the composite container 1 is formed, the front surface (the forming surface of the wing portion 11) of the packaging bag 2 that contains the contents N is placed on the inner surface of the front surface portion 20 a of the exterior body 20 and bonded by the bonding portion 40. Next, the exterior body 20 is bent at the bent portion 21 and bonded at the joining portion 27, and the back surface of the packaging bag 2 is bonded to the back surface portions 20 b and 20 c by the bonding portion 40.

  A product name or the like is printed on the front surface portion 20a on which the joining portion 27 is not formed in order to avoid a decrease in aesthetic appearance on the exterior body 20. For this reason, a user recognizes the front part 20a as the front side of goods, and the wing part 11 is arrange | positioned at the front side. The exterior body 20 is printed with an instruction to heat the range by placing the wing portion 11 on the upper surface.

  In the composite container 1 having the above-described configuration, in order to eat the contents N, the composite container 1 is installed in a microwave oven with the wing part 11 facing upward and heated by the microwave oven. At this time, the user arranges the surface recognized as the front surface side on the normal upper surface, so that it is possible to prevent erroneous arrangement with the wing portion 11 facing downward.

  When the composite container 1 is heated by the microwave oven, the packaging bag 2 expands. At this time, the front surface and the back surface of the exterior body 20 are curved outward along the expanding packaging bag 2. The expansion of the packaging bag 2 causes the thermal bonding portion 2c around the isolation portions 6a and 6b to peel and retract. When the separating part 6a or the separating part 6b and the storage space 8 communicate with each other by peeling of the heat bonding part 2c, the steam in the packaging bag 2 flows out through the steaming hole 7a or the steaming hole 7b. Thereby, rupture of the packaging bag 2 can be prevented and the contents N can be heated.

  Usually, since the isolation part 6a near the center part of the packaging bag 2 communicates with the storage space 8 earlier than the isolation part 6b, the isolation part 6b and the storage space 8 do not communicate with each other due to the outflow of steam. However, when the peeling of the thermal bonding part 2c around the isolation part 6a does not proceed, the isolation part 6b and the storage space 8 communicate with each other and steam flows out. Thereby, rupture of the packaging bag 2 can be reliably prevented.

  Moreover, since the strength of the back surface of the exterior body 20 on which the joining portion 27 is arranged is higher than that of the front surface, the front surface of the exterior body 20 is more easily curved than the back surface. For this reason, the front surface of the packaging bag 2 is easily expanded without being obstructed by the exterior body 20, and the thermal bonding portion 2 c around the isolation portions 6 a and 6 b provided in the wing portion 11 can be reliably peeled off. In addition, since the upper end of the exterior body 20 is disposed below the center with respect to both ends in the left-right direction, the packaging bag 2 can be more easily inflated without being obstructed by the exterior body 20.

  When the heating of the composite container 1 is completed, as shown in FIG. 6, the notch 10 of the packaging bag 2 is cut and the packaging bag 2 is opened. And if the pushing part 24 is pressed inward with a finger, the front surface and the back surface of the exterior body 20 will curve, and it will deform | transform into the state in which the exterior body 20 can become independent. Thereby, the content N can be taken out and eaten in the state which made the composite container 1 self-supporting.

  At this time, since the upper end of the exterior body 20 is arranged upward with respect to the central portion in the left-right direction, the composite container 1 can be stably erected at the time of eating. In addition, both side portions of the bottom portion of the exterior body 20 are spread back and forth by folding lines 25 and 26. Thereby, the composite container 1 can be erected more stably.

  In addition, since the notch 10 is disposed between the wing portion 11 and the upper end of the exterior body 20, the distance between the opening surface 2 d cut by the notch 10 and the bottom surface of the packaging bag 2 is shortened. Thereby, the content N can be taken out easily.

  According to the present embodiment, the steaming holes 7a and 7b are opened in the isolation parts 6a and 6b where the wing part 11 is isolated from the storage space 8, and the pushing part 24 is pushed inward to The back surface is curved and the exterior body 20 is deformed into a state where it can stand on its own. Thereby, when the composite container 1 is heated by the microwave oven, the vapor flows out from the steaming holes 7a and 7b, so that the composite container 1 can be laid and heated. Further, the contents N can be eaten by making the composite container 1 self-supporting due to the deformation of the exterior body 20. Therefore, the composite container 1 can be heated and eaten without being restricted by the height of the microwave oven, and the convenience of the composite container 1 can be improved.

  Moreover, the exterior body 20 has the joining part 27 to which the both ends of the circumferential direction of a paperboard are piled up, and faces the surface (back surface) opposite to the surface (front surface) in which the wing part 11 of the packaging bag 2 was provided. The coalescence part 27 was arranged. Thereby, the front surface which provided the wing part 11 of the packaging bag 2 expand | swells easily by heating, and the heat bonding part 2c around the isolation | separation parts 6a and 6b provided in the wing part 11 can be peeled reliably.

  In addition, the upper end of the outer package 20 is arranged with the center portion downward with respect to both ends in the left-right direction. Thereby, the packaging bag 2 can be easily inflated when the composite container 1 is heated, and can be erected stably in a meal.

  A notch 10 for tearing provided at the left and right ends of the packaging bag 2 is disposed between the wing portion 11 and the exterior body 20. Thereby, the distance of the opening surface 2d and the bottom face cut by the notch 10 can be shortened, and the contents N can be easily taken out.

  Further, the fold line 22 and the fold line 23 sandwiching the bent portion 21 of the push-in portion 24 are inclined upward and downward in the left-right direction with respect to the central portion in the vertical direction. The upper end of the fold line 22 and the upper end of the fold line 23 are connected by a slit 28a, and the lower end of the fold line 22 and the lower end of the fold line are connected by a slit 28b. Thereby, the pushing part 24 which can hold | maintain the state pushed when pressing the bending part 21 is easily realizable.

  In the present embodiment, the packaging bag 2 made of a flat pouch can be lifted at the center in the left-right direction when the composite container 1 is self-supporting, so it may be difficult to take out the contents N at the left and right ends of the bottom. For this reason, you may form the lower end of the adhesion part 40 of the front side of the packaging bag 2, and a back side in a different height. Thereby, when making the composite container 1 self-supporting, the bottom part of the packaging bag 2 inclines in the front-back direction. At this time, the left and right ends of the bottom portion of the packaging bag 2 are pulled and lifted, and the contents N at the left and right ends of the bottom portion can be easily taken out.

  Moreover, in this embodiment, you may form the packaging bag 2 with the bottom gusset type bag which heat-welded the laminated | multilayer film which forms a bottom face between the bottom part of the laminated | multilayer film 4, and the bottom part of the laminated | multilayer film 5. FIG.

Second Embodiment
Next, FIG. 7 has shown the front view of the packaging bag 2 of the composite container 1 of 2nd Embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIGS. This embodiment differs in the shape of the lower part of the packaging bag 2 with respect to 1st Embodiment. Other parts are the same as those in the first embodiment.

  Inclined portions 30 are provided at the left and right ends of the bottom portion of the packaging bag 2 made of a flat pouch. The inclined portion 30 is inclined downward toward the center of the packaging bag 2 in the left-right direction. For this reason, the packaging bag 2 is formed in a substantially trapezoidal shape. Further, the lower end of the bonding portion 40 is disposed above the upper end (the B line in the drawing) of the inclined portion 30.

  When the composite container 1 is made self-supporting by pushing in the pushing portion 24, the bottom of the packaging bag 2 is lifted at the center portion in the left-right direction. At this time, the contents N at the left and right ends of the bottom of the packaging bag 2 can be easily taken out by the inclined portion 30. Moreover, since the adhesion part 40 is distribute | arranged above the inclination part 30, the downward direction rather than the inclination part 30 is expanded in the front-back direction. Thereby, the contents N at the left and right ends of the bottom of the packaging bag 2 can be taken out more easily.

  According to this embodiment, the same effects as those of the first embodiment can be obtained. Moreover, since the packaging bag 2 has the inclined part 30, even if the center part of the bottom face of the packaging bag 2 rises by pushing of the pushing part 24, the contents N at the left and right ends of the bottom part can be easily taken out. it can.

  Further, the lower end of the bonding portion 40 is disposed above the upper end (the B line in the drawing) of the inclined portion 30. Thereby, the bottom part of the packaging bag 2 can be easily extended in the front-back direction at the time of eating.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the composite container which covers the packaging bag which stores the contents, such as foodstuff, with a cylindrical exterior body.
