Description

  The present invention relates to a microwave oven packaging body having a chuck member.

  A conventional microwave heating packaging is disclosed in Patent Document 1. The microwave oven heating package includes a bag body and a chuck member. The bag body is hermetically sealed by overlapping resin sheets and sealing the periphery with a seal portion, and has a front surface portion and a back surface portion facing each other. The chuck member is disposed on the inner surface of the upper part of the front part and the rear part, and a storage part for storing contents such as a cooking sauce is formed below the chuck member. A cut line extending in the left-right direction is formed on the outer surface of the front surface portion and the back surface portion between the upper edge portion of the bag body and the chuck member.

  The chuck member has a male part projecting on a band-shaped first base fixed to the back surface part, and a female part projecting on the band-shaped second base fixed to the front surface part and meshing with the male part. . A steaming portion that is crushed and does not fit the male portion and the female portion is formed at one end of the chuck member.

  Further, the second base portion of the chuck member is formed of a tape-like member having an easy peel property, and the lower end of the second base portion of the chuck member extends rearward and is bonded to the inner surface of the back surface portion below the first base portion. Thereby, it is prevented that the content in a storage part leaks from a steaming part.

  In the microwave oven package having the above configuration, when the user breaks the front surface portion and the back surface portion along the cut line, the bag body is opened. When the user grips the upper ends of the front and rear portions broken by the cut line and pulls them away from each other, the lower end of the second base breaks and the chuck member opens. Thereby, the upper surface of a storage part is opened.

  Then, a user accommodates foodstuffs etc. in a storage part, closes a chuck member, and heats a microwave oven heating packing object with a microwave oven. Thereby, it can cook by putting a foodstuff into a cooking sauce. At this time, the steam generated in the storage part by heating is exhausted through the steaming part. As a result, it is possible to prevent a bursting sound or scattering of contents due to the entire chuck member being opened at once due to an increase in internal pressure in the bag body.

<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1: has shown the front view of the package for a microwave oven heating of this embodiment. The microwave oven heating package 1 is formed by a so-called standing pouch, and has a bag body 2 and a chuck member 3. The chuck member 3 is formed of resin and is disposed on the inner surface of the upper portion of the bag body 2.

  The bag body 2 has a front surface portion 22 and a back surface portion 23 facing each other, with the resin sheet 100 overlapped and the periphery sealed (thermally bonded) by the first seal portion 21. Further, the first seal portion 21 seals the periphery of the bottom surface portion 8 made of the resin sheet 100 folded in half at the lower end portions of the front surface portion 22 and the back surface portion 23. The bottom surface portion 8 has a plurality of unbonded portions 9 that are not thermally bonded at the left and right end portions, respectively. The unbonded portion 9 can prevent bubbling or curling of the bottom surface portion 8 during the heat bonding process.

  A storage portion 4 that stores the contents (cooking sauce S in this embodiment) is formed below the chuck member 3 of the bag body 2. A steaming portion 5 that communicates with the storage portion 4 by heating is provided at an upper portion of one side end of the storage portion 4. In addition, although cooking sauce S is used as a content in this embodiment, there is no limitation in particular in a content.

  The steaming part 5 has a second seal part 52 and a hole part 51. The second seal portion 52 is formed in a substantially semi-annular shape having both ends connected to the right first seal portion 21, and thermally bonds both surfaces of the front surface portion 22 and the back surface portion 23 (both surfaces facing the bag body 2). The adhesive strength of the second seal portion 52 is formed substantially the same as the adhesive strength of the first seal portion 21 at the side end, and the width W2 of the second seal portion 52 is smaller than the width W1 of the first seal portion 21 at the side end. It has become. In addition, the second seal part 52 has a projecting part 52a that is arranged in a biased manner on the upper part of the storage part 4 and protrudes downward by bending. The second seal portion 52 is thermally bonded simultaneously with the first seal portion 21 at the side end.

  The hole portion 51 opens in the front surface portion 22 and the back surface portion 23, and is disposed inside the second seal portion 52. Thereby, the hole 51 is formed through the bag body 2 and is surrounded by the first seal portion 21 and the second seal portion 52. As will be described later, when the microwave heating package 1 is heated by the microwave, the vapor in the storage unit 4 is exhausted to the outside of the microwave heating package 1 through the hole 51.

  A V-shaped notch 29 is formed on the first seal portion 21 on both side edges of the bag body 2 above the chuck member 3. In addition, you may provide the cutting line which half-cuts the front-surface part 22 and the back surface part 23, and is substantially connected with the notch part 29 on either side.

  Information (characters, designs, etc.) on the cooking sauce S such as the cooking method is printed on the outer surfaces of the front surface portion 22 and the back surface portion 23. In addition, the information printed on the outer surface of the front surface part 22 and the back surface part 23 may be other information (for example, a picture of a landscape, etc.) other than the information regarding the cooking sauce S. Moreover, you may stick the sheet | seat on which the information regarding the cooking sauce S and other information were printed on the outer surface of the front part 22 and the back part 23. FIG.

  The resin sheet 100 is formed by, for example, laminating a base material layer, a printing layer, an adhesive layer, an intermediate layer, an adhesive layer, and a sealant layer (all not shown) in order from the outside to the inside of the bag body 2. The base material layer is formed of, for example, a biaxially stretched transparent vapor-deposited polyethylene terephthalate film having a thickness of about 12 μm. The printing layer is formed to a thickness of about 1 to 5 μm with ink disposed at a predetermined position on the base material layer.

  The intermediate layer is formed, for example, by vapor-depositing silica or the like on a biaxially stretched nylon film having a thickness of about 15 μm, and prevents permeation of water vapor, oxygen and the like. The sealant layer (thermal adhesive resin layer) is formed of, for example, an unstretched polypropylene (CPP) film having a thickness of about 60 μm, and the sealant layers facing each other are sealed. The adhesive layer that bonds the base material layer including the printed layer and the intermediate layer and the adhesive layer that bonds the intermediate layer and the sealant layer are each formed to a thickness of about 5 μm by a dry lamination method.

  For example, the resin sheet 100 may be formed by laminating a base material layer, an intermediate layer, a printing layer, an adhesive layer, an intermediate layer, an adhesive layer, and a sealant layer in order from the outer side to the inner side of the bag body 2.

  FIG. 2 shows a side cross-sectional view of the chuck member 3 of the microwave heating packaging 1. The chuck member 3 has a first occlusion portion 31 and a second occlusion portion 32 extending in the left-right direction. The first occlusal portion 31 protrudes from a belt-shaped first base portion 35 bonded to the inner surface of the back surface portion 23. The second occlusal portion 32 protrudes from a belt-like second base portion 36 bonded to the inner surface of the front surface portion 22 and engages with the first occlusion portion 31.

  The first base portion 35 is thermally bonded to the back surface portion 23 in the bonding region HS above and below the first occlusal portion 31. The second base portion 36 is thermally bonded to the front surface portion 22 at an adhesive region HS above the second occlusal portion 32, and is not bonded to the bag body 2 below the second occlusal portion 32.

  The first occlusion portion 31 is provided with a male portion 31a having claw portions 31c and 31b on the upper surface and the lower surface, respectively. The claw portion 31b protrudes from the lower surface of the column portion 31e protruding on the first base portion 35 and is bent rearward (on the first base portion 35 side), and the claw portion 31c protrudes upward from the upper surface of the column portion 31e.

  The second occlusion portion 32 is provided with a female portion 32a having claw portions 32b and 32c on the upper and lower sides. The male part 31a is fitted between the claw parts 32b and 32c, and the claw parts 31b and 31c are engaged with the claw parts 32b and 32c, respectively.

  The first occlusal portion 31 has an L-shaped engagement claw 31d below the male portion 31a, and the second occlusion portion 32 is engaged with the engagement claw 31d below the female portion 32a. It has an engaging claw 32d. The engaging claw 31d protrudes on the first base 35 and bends downward with its tip directed rearward. The engaging claw 32d protrudes on the second base portion 36 and bends upward with its tip directed forward.

  FIG. 3 shows an enlarged side sectional view of the first occlusal portion 31. The inclination angle θ1 of the lower claw part 31b is formed at an acute angle with respect to the column part 31e of the male part 31a, and the inclination angle θ2 of the upper claw part 31c is formed at a substantially right angle. For this reason, the fitting strength of the claw portion 31b with respect to the female portion 32a (see FIG. 2) is larger than the fitting strength of the claw portion 31c. In addition, you may form the inclination-angle (theta) 2 of the nail | claw part 31c in an obtuse angle.

  Further, since the tips of the engaging claws 31d and the engaging claws 32d (see FIG. 2) extend rearward, the engaging strength of the engaging claws 31d and 32d is larger than the fitting strength of the claw portion 31c. Therefore, when the chuck member 3 is opened from below, a larger force than that from above is required. The engaging claws 31d and the engaging claws 32d may be omitted.

  The microwave oven packaging body 1 configured as described above is formed with the upper end of the bag body 2 unsealed, and the chuck member 3 is opened and the cooking sauce S is filled into the storage unit 4 from above. Thereafter, the upper end portions of the front surface portion 22 and the back surface portion 23 are sealed by a heat seal device or the like, and the first seal portion 21 is formed above the chuck member 3. Thereby, the bag main body 2 is sealed in a state where the cooking sauce S is stored in the storage unit 4.

  When the user breaks the upper portion of the bag body 2 from the notch portion 29, the microwave heating package 1 is opened. Thereafter, the chuck member 3 is opened, the food F is stored in the storage portion 4, and the chuck member 3 is closed. And the microwave oven heating packaging body 1 is stood and heated in the microwave oven, and the food F is mixed with the cooking sauce S in the accommodating part 4, and cooking is performed.

  FIG. 4 shows a front view of the microwave oven heating packaging 1 during heating in the microwave oven. FIG. 5 shows a cross-sectional view taken along the line AA of FIG. When the steam VP is generated from the food F and the cooking source S by heating in the microwave, the internal pressure in the storage unit 4 increases.

  The second seal portion 52 of the steaming portion 5 is formed to have a width W2 (see FIG. 1) narrower than the width W1 (see FIG. 1) of the first seal portion 21. For this reason, the second seal 52 is peeled off by leaving the peeling mark 55 on the inner surface of the bag body 2 before the first seal 21 due to the internal pressure of the storage portion 4. Thereby, the storage unit 4 and the steaming unit 5 communicate with each other, and the vapor VP in the storage unit 4 is exhausted to the outside of the microwave oven heating packaging body 1 through the hole 51. Since the steaming part 5 is arranged in the upper part of the storage part 4, the leakage of the contents from the steaming part 5 is prevented.

  In addition, since the second seal portion 52 has a protruding portion 52a that protrudes downward due to the curvature, the force in the direction of separating the front surface portion 22 and the back surface portion 23 when the storage portion 4 is expanded by steam concentrates on the protruding portion 52a. To do. Thereby, peeling of the 2nd seal | sticker part 52 from the protrusion part 52a is started easily.

  At this time, the vapor enters the space K (see FIG. 2) between the second base portion 36 and the front surface portion 22 that are not bonded to the bag body 2 below the second occlusion portion 32. For this reason, the lower part of the 2nd base 36 moves toward the 1st base 35 as shown by arrow B (refer to Drawing 2) by internal pressure, and opening of chuck member 3 is controlled. Therefore, the opening of the chuck member 3 before the communication between the storage unit 4 and the steaming unit 5 is prevented, and the burst sound and the scattering of the contents due to the entire chuck member 3 being opened at once are prevented.

  After heating in the microwave oven, the user opens the chuck member 3 again, and transfers the food F cooked in the cooking sauce S to a dish or the like. Thereby, the user can eat the contents cooked with the microwave oven.

  Using the microwave oven heating package 1 of the present embodiment, an experiment on the generation of a burst sound of the microwave oven heating package 1 during heating in the microwave oven was performed. Biaxially stretched transparent vapor-deposited polyethylene terephthalate film (trade name: IBPET-PIR, manufactured by Dai Nippon Printing Co., Ltd.) with a thickness of 12 μm as the base layer of the resin sheet 100, and biaxially stretched vapor-deposited nylon with a thickness of 15 μm as the intermediate layer An unstretched polypropylene film (trade name: ZK207, manufactured by Toray Industries, Inc.) having a thickness of 60 μm was used as a film (trade name: ONMB, manufactured by Unitika Ltd.) and a sealant layer. In the packaging for microwave oven heating of the comparative example, the first base 35 is bonded to the back surface 23 above and below the first occlusal portion 31, and the second base 36 is a front portion above and below the second occlusion portion 32. Bonded to 22. Other configurations of the comparative example are the same as those of the present embodiment.

  Ingredient F (vegetables) was put into this embodiment and a comparative example, and it heated for 3 minutes and 50 seconds at 500W using a microwave oven. In this embodiment and the comparative example, an experiment was performed on 100 samples. As a result of the experiment, in this embodiment, the vapor VP was exhausted to the outside of the storage unit 4 through the hole 51 of the steaming unit 5 without generating a plosive sound without opening the chuck member 3 in all the samples. . On the other hand, in the comparative example, the chuck member 3 was opened in 27 samples, and a large burst sound was generated.

  According to the present embodiment, the steaming part 5 communicating with the storage part 4 by heating is provided below the chuck member 3. In addition, the first base 35 of the chuck member 3 is bonded to the bag body 2 above and below the first occlusion portion 31, and the second base 36 is bonded to the bag body 2 above the second occlusion portion 32 and below. The bag body 2 is not bonded. Thereby, the structure of the chuck member 3 can be simplified, the opening of the chuck member 3 due to the internal pressure can be prevented, and the steam can be exhausted from the steaming portion 5. Therefore, it is possible to provide an inexpensive microwave heating packaging 1 that can be easily manufactured without using a tape-like member having an easy peel property as in the conventional example.

  Further, the steaming part 5 includes a second seal part 52 that is narrower than the first seal part 21, and a hole part 51 that opens in the front part 22 and the back part 23 and is provided inside the second seal part 52. Have. Thereby, the steaming part 5 which communicates with the storage part 4 and exhausts steam by an increase in internal pressure due to heating can be easily realized.

  Moreover, the 2nd seal | sticker part 52 has the protrusion part 52a which is biased and arrange | positioned above the accommodating part 4, and protrudes below by curve. Thereby, the force in the direction of separating the front surface portion 22 and the back surface portion 23 by the internal pressure concentrates on the protrusion 52a, and the separation of the second seal portion 52 from the protrusion 52a is easily started. Therefore, the opening of the chuck member 3 due to the internal pressure can be prevented more reliably.

  Further, when the chuck member 3 is opened from below, a larger force is required than when it is opened from above, so that when the microwave heating package 1 is heated in the microwave oven, the chuck member 3 is further opened from the storage unit 4 side. It becomes difficult to be done. On the other hand, the user can easily open the chuck member 3 from the outside of the storage portion 4. Therefore, the convenience of the microwave oven heating package 1 can be improved. The fitting strength required when opening the chuck member 3 from below is preferably 50 N / mm or more.

  In addition, a male part 31a having claw parts 31b and 31c on the upper and lower surfaces is provided on the first occlusion part 31 and a female part 32a is engaged with the second occlusion part 32 and engaged with the claw parts 31b and 31c. Is provided. The fitting strength of the claw portion 31b below the male portion 31a is larger than the fitting strength of the upper claw portion 31c. Thereby, the chuck | zipper member 3 which can prevent the opening | release at the time of a heating and can open | release easily by a user is easily realizable.

  Moreover, the 1st occlusion part 31 and the 2nd occlusion part 32 have the L-shaped engagement nail | claw 31d and 32d which mutually engage below the male part 31a and the female part 32a. Thereby, the opening of the chuck member 3 at the time of heating the packaging body 1 for heating a microwave oven in a microwave oven can be further prevented. The engagement strength between the engagement claw 31d and the engagement claw 32d is preferably 50 N / mm or more.

  In the present embodiment, the first base portion 35 having the first occlusion portion 31 may be provided on the front surface portion 22, and the second base portion 36 having the second occlusion portion 32 may be provided on the back surface portion 23. Alternatively, the male portion 31 a and the engaging claw 31 d may be formed in the second occlusion portion 32, and the female portion 32 a and the engaging claw 32 d may be formed in the first occlusion portion 31.

Second Embodiment
Next, a second embodiment of the present invention will be described. 6 and 7 show front views of the microwave heating package before opening and heating in the microwave according to the second embodiment, respectively. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. In the present embodiment, the configuration of the steaming unit 5 is different from that of the first embodiment. Other parts are the same as those in the first embodiment.

  An unsealed portion 27 in which the front surface portion 22 and the back surface portion 23 are not sealed is provided outside the second seal portion 52 at the right end portion of the upper portion of the bag body 2. A hole 53 that communicates with the outside of the bag body 2 is provided at the side end 27 a of the unsealed portion 27. Thereby, the hole 53 of the steaming part 5 divides the first seal part 21 on the right side and opens to the periphery of the bag body 2. The outer end portion 52 g of the second seal portion 52 faces the unsealed portion 27.

  An unbonded portion 25 that is not thermally bonded is formed at the same height as the hole 53 at the left end of the left first seal portion 21. Thereby, in the manufacturing process of the packaging body 1 for microwave oven heating, when cutting between the adjacent microwave heating packaging bodies 1 along the 1st seal part 21 of the side end extended in an up-down direction, it is a cutting position by processing accuracy. Even in the case of deviation, the blockage of the hole 53 can be prevented.

  When the microwave oven heating packaging body 1 storing the food F in the storage portion 4 is heated in the microwave oven and the internal pressure of the storage portion 4 rises, the second seal portion 52 is moved to the first seal portion 21 by the internal pressure of the storage portion 4. Prior to this, peeling is performed leaving a peeling mark 55 on the inner surface of the bag body 2. Thereby, the storage unit 4 and the steaming unit 5 communicate with each other, and the steam VP in the storage unit 4 is exhausted to the outside of the microwave oven heating packaging body 1 through the hole 53.

  In this embodiment, the same effect as that of the first embodiment can be obtained. Further, the hole 53 of the steaming part 5 divides the first seal part 21 and opens at the periphery of the bag body 2. Thereby, the operation | work which drills the hole 51 in the front part 22 and the back part 23 like 1st Embodiment can be omitted.

  The second seal portion 52 of the steaming portion 5 is formed in a semicircular shape with both ends connected to the first seal portion 52, and thermally bonds the front surface portion 22 and the back surface portion 23. The hole portion 51 of the steaming portion 5 is formed only on the front surface portion 22 and is surrounded by the second seal portion 21 and the second seal portion 52. Instead of the front surface portion 22, the hole portion 51 may be formed only in the back surface portion 23.

  When the microwave oven heating packaging body 1 storing the food F in the storage portion 4 is heated in the microwave oven and the internal pressure of the storage portion 4 rises, the second seal portion 52 is moved to the first seal portion 21 by the internal pressure of the storage portion 4. Prior to this, peeling is performed leaving a peeling mark 55 on the inner surface of the bag body 2. Thereby, the storage unit 4 and the steaming unit 5 communicate with each other, and the vapor VP in the storage unit 4 is exhausted to the outside of the microwave oven heating packaging body 1 through the hole 51.

  In this embodiment, the same effect as that of the first embodiment can be obtained.

<Fourth embodiment>
Next, a fourth embodiment of the present invention will be described. FIG.10 and FIG.11 has each shown the front view of the package body for microwave oven heating before the opening of 4th Embodiment, and the time of the heating in a microwave oven. For convenience of explanation, the same reference numerals are given to the same parts as those of the first embodiment shown in FIGS. 1 to 5 and the second embodiment shown in FIGS. In the present embodiment, the configuration of the second seal portion 52 of the steaming portion 5 is different from that of the second embodiment. Other parts are the same as those in the first embodiment and the second embodiment.

Heat bond. An unsealed portion 27 is provided outside the second seal portion 52 at the right end portion of the upper portion of the bag body 2. The unsealed portion 27 communicates with the outside of the bag body 2 through a hole 53 provided in the side end portion 27a. The outer end portion 52 g of the second seal portion 52 faces the unsealed portion 27. Further, the lower corner portion 52e of the second seal portion 52 is formed at a substantially right angle.

  An unbonded portion 25 that is not thermally bonded is formed at the same height as the hole 53 at the left end portion of the left first seal portion 21. Thereby, in the manufacturing process of the packaging body 1 for microwave oven heating, when cutting between the adjacent microwave heating packaging bodies 1 along the 1st seal part 21 of the side end extended in an up-down direction, it is a cutting position by processing accuracy. The hole 53 can be reliably formed even when the position is shifted.

  When the microwave oven heating packaging body 1 storing the food F in the storage portion 4 is heated in the microwave oven and the internal pressure of the storage portion 4 rises, the second seal portion 52 is moved to the first seal portion 21 by the internal pressure of the storage portion 4. Prior to this, peeling is performed leaving a peeling mark 55 on the inner surface of the bag body 2. Thereby, the storage unit 4 and the steaming unit 5 communicate with each other, and the steam VP in the storage unit 4 is exhausted to the outside of the microwave oven heating packaging body 1 through the hole 53.

  At this time, the force in the direction of separating the front surface portion 22 and the back surface portion 23 due to the internal pressure concentrates on the corner portion 52e, and the second seal portion 52 is easily peeled off from the corner portion 52e. Therefore, the opening of the chuck member 3 due to the internal pressure can be prevented more reliably.

  In this embodiment, the same effect as that of the first embodiment can be obtained.

  In the second embodiment and the fourth embodiment, the unsealed portion 27 may be cut off from the bag body 2. That is, a substantially U-shaped cutout portion may be provided outside the second seal portion 52, and the outer end portion 52g of the second seal portion 52 may face the cutout portion. In this case, when the microwave oven heating packaging 1 is heated in the microwave oven, the storage portion 4 and the steaming portion 5 communicate with each other, and the steam VP in the storage portion 4 is for heating the microwave oven through the notch. It is exhausted to the outside of the package 1.

  Moreover, in 1st Embodiment-4th Embodiment, although the package 1 for microwave oven heating is formed with the standing pouch, it is not limited to this. For example, you may form the microwave oven packaging 1 with what is called a three-side seal bag, a four-side seal bag, etc. FIG.

  Moreover, in 1st Embodiment-4th Embodiment, it replaces with the cooking sauce S, a cosmetic liquid etc. are accommodated in the accommodating part 4, and the cloth etc. in the accommodating part 4 are opened after opening the packaging body 1 for microwave oven heating. And the microwave heating package 1 may be heated in a microwave oven. In this case, the cosmetic effect can be improved by covering the eyes of the user with the heated cloth.

  The present invention can be used for a microwave oven packaging body having a chuck member.
