Description

  The present invention relates to a packaged food for cooked rice food and a packaged rice cooked food product in which a sheet-shaped food and a cooked rice processed food are packaged in a separated state, and the sheet-shaped food and the cooked rice processed food are integrated when opened.

  Traditionally, as a packaged food for processed cooked rice for packaging processed cooked rice sold at supermarkets and convenience stores, etc., sheet food and cooked cooked food are packaged in a separate state, and when opened, sheeted food and cooked rice processed food are used. The mainstream is the one that is configured to be integrated with each other.

  Such a packaged food for cooked rice food has a substantially rectangular shape in plan view and an outer film formed so as to be splittable in another direction (width direction) perpendicular to one direction (longitudinal direction) and the sheet-like food. The outer film and the inner film are sealed so as to surround the sheet-like food. The inner film is superposed on the film and is separated from the outer film in the same direction.

  The outer film is generally provided with cutting means for cutting in one direction at the center in the width direction, and can be divided into two in the width direction by cutting in one direction with the cutting means. Yes. On the other hand, the inner film is composed of two films arranged in parallel in the width direction of the outer film, and the two films can be separated in the same direction as the outer film.

  The packaged food for cooked rice food having the above-described structure is a state in which the cooked rice cooked food is placed on the inner film, and is folded in two in one direction of the outer film and heat-sealed opposite ends. The processed rice food and sheet-like food can be packaged in a state separated by a film.

Then, the packaged food for cooked rice food is obtained by cutting the outer film and pulling it in the width direction so that the outer film and the inner film (two films) separated from each other are separated (separated). The inner film (two films) between the rice and the cooked rice food is extracted. Thereby, the sheet-like food and the cooked rice processed food can be integrated with the opening (see, for example, Patent Document 1).
JP 2006-264758 A

  However, the packaged food for cooked rice processed food having the above structure cannot be opened unless it is pulled in the width direction after the outer film is cut by a cutting means at the time of opening, and the opening operation is complicated. In addition, such packaged food for cooked rice must directly grip the cooked cooked food integrated with the sheet-shaped food after opening, and the hand of the person eating the cooked cooked food is dirty There are also problems such as being unsanitary.

  Therefore, in view of such circumstances, the present invention can be integrated to open the sheet-shaped food and the cooked rice food by simply pulling without breaking at the time of opening, and is integrated with the sheet-shaped food. It is an object of the present invention to provide a packaged food for cooked rice food and a packaged rice cooked food product that can eat the cooked cooked food hygienically without directly grasping the cooked cooked rice food.

  The packaging material for cooked rice processed food according to the present invention is configured so that the sheet-shaped food and the cooked rice processed food can be packaged in a separated state, and the packaged sheet-shaped food and the cooked rice processed food can be opened integrally. In the configured cooked rice food packaging material, each of the outer film part having a substantially square shape in plan view and the other film part in parallel with each other perpendicular to one direction of the outer film part are attached to each other and attached to each other. A pair of first inner film portions whose base ends are separably connected to both side ends of the outer film portion, and the first inner film portions extend from the distal ends, and a bent ridge line is formed at the boundary between the first inner film portions. A pair of second inner film portions that are folded back with the leading ends outward, and a sheet-like food is interposed between the outer film portion and the first inner film portion. The inner film part is the outer film part. Both ends of the direction are sealed so as to be peelable, and the second inner film part is folded in half in one direction of the outer film part with the second inner film part inside so as to wrap the cooked rice processed food. It is characterized by packaging the cooked rice processed food by sealing the ends. Here, “attaching the tip” means not only that the tips are opposed to each other in contact, but also that the tips are overlapped. “Seal” means heat sealing or ultrasonic This includes not only welding by a seal but also adhesion via an adhesive.

  According to the packaging material for cooked rice processed food having the above configuration, the first inner film portion and the second inner film portion are interposed between the sheet-like food and the cooked rice processed food in a state where the cooked rice processed food is packaged. The sheet-like food and the cooked rice processed food can be separated from each other, and the moisture of the cooked rice processed food can be prevented from reaching the sheet-like food and deteriorating the taste and texture. .

  And when this rice cooked food packaging material is pulled in the direction which mutually separates the tip side of each 2nd inner film part in the state which packed the cooked rice processed food, it is the 1st inner film part and the 2nd inner film part. The bent ridge line at the boundary moves from the distal end side to the proximal end side of the first inner film portion. That is, when the distal end portions of the pair of second inner film portions are pulled, the bent ridge line formed at the boundary between the first inner film portion and the second inner film portion is the proximal end from the distal end side in the first inner film portion. The leading end sides of the first inner film portions that are attached to each other follow the movement (pulling) of the second inner film portion and are pulled out to the outside.

  Thereby, the sheet-like food separated from the cooked rice processed food is exposed between the pair of first inner film portions (second inner film portions) by the pair of first inner film portions and the pair of second inner film portions. Will be integrated with processed rice food.

  And in accordance with the integration of the sheet-like food and the cooked rice processed food, the outer film part that is peelably sealed by the pulling action on the pair of second inner film parts, and both ends of the first inner film part are peeled off. After that, the base ends of the pair of first film portions are finally separated from the side ends of the outer film portion, and the first inner film portion and the second inner film portion are separated from the outer film portion. If it does so, only the substantially two-fold outer film part will remain around the cooked rice processed food united with the sheet-like food. Thereby, the cooked rice processed food integrated with the sheet-like food can be grasped by hand through the outer film portion.

  As one aspect of the present invention, it is preferable that the distal end portion of the second inner film portion extends outward from the proximal end of the first inner film portion. Such a packaged food for cooked rice food is in a state in which the cooked rice cooked food is packaged, and each second inner film portion is folded in half inside the outer film portion and the first inner film portion. If the tip of the second inner film part extends outside the base end of the first inner film part, it becomes easier to grip the end part of the second inner film part during opening, and operability during opening Will be improved.

  As another aspect of the present invention, the base end portion of the first inner film portion is peelably sealed to the side end portion of the outer film portion so that the base end of the first inner film portion is at the side end of the outer film portion. It is preferable that they are connected in a separable manner. If it does in this way, since the base end part of the 1st film part will peel from the side edge part of an outer film part by the pulling force to the other direction at the time of opening, these can be separated smoothly.

  Moreover, it is preferable that the front-end | tip parts of a pair of 1st inner film part are sealed in one direction so that peeling is possible. If it does in this way, between a pair of 1st inner film parts will be obstruct | occluded, In the state which packed the cooked rice processed food, the water | moisture content will reach | attain a sheet-like food via between 1st inner film parts. Can be reliably prevented. Thereby, it can prevent more reliably that the taste, food texture, etc. of a sheet-like food are reduced.

  And as for the 2nd inner film part, it is preferable that the embossing is given to the surface facing at least cooked rice processed food. If it does in this way, the resistance between the 2nd inner film part produced at the time of opening and the cooked rice processed food will become small, and it can open easily, without making the cooked rice processed food out of shape.

  The cooked rice processed food package according to the present invention is characterized in that the cooked rice processed food is packaged with any one of the above-described cooked rice processed food packaging materials. Since the cooked rice processed food package is packaged with any of the above-described cooked rice processed food packaging materials, the sheet-like food and cooked rice processed by pulling the second inner film portion as described above. The food can be opened integrally with the food, and the cooked rice processed food can be grasped by hand through the outer film in the opened state.

  As described above, according to the cooked rice processed food packaging material and the cooked rice processed food packaging body according to the present invention, the sheet-like food and the cooked rice processed food can be opened together by simply pulling without breaking during opening. In addition, it is possible to produce an excellent effect that the cooked rice processed food can be eaten hygienically without directly grasping the cooked rice processed food integrated with the sheet-like food.

The length is set to be longer than the protruding amount, and the end portions extend outward from the base ends of the first inner film portions 20 and 20.

  The cooked rice processed food packaging material 1 according to the present embodiment includes an outer film part 10, first inner film parts 20, 20, and a second inner film part 30, as shown in FIGS. 3 (a) to 3 (e). , 30 are formed by bending, sealing, and cutting a single resin film F. More specifically, the resin film F for forming the packaging material 1 for cooked rice processed food is formed in a substantially rectangular shape in plan view, and has a length in the longitudinal direction as shown in FIG. , The length in the width direction of the outer film part 10, the total extension amount of the pair of first inner film parts 20, 20, the total extension amount of the pair of second inner film parts 30, 30, a pair of cut areas described later (Removal allowance) The total length of 10 a ′ is set to the total length, and the length in the short direction perpendicular to the longitudinal direction is set to the length in the longitudinal direction of the outer film portion 10.

  And as for this resin film F, the center area | region (area | region set to the length of the width direction of the outer film part 10 in the longitudinal direction of the resin film F) including the centerline extended in a transversal direction is the said outer film part. The first region 10 ′ is set to 10 and a region having a predetermined width adjacent to both sides of the first region 10 ′ is a first region 10 ′ and later-described second regions 20 ′ and 20 ′. The predetermined regions (extensions of the first inner film portions 20 and 20 in the longitudinal direction of the resin film F) that are set in the excision regions 10a ′ and 10a ′ and are separated on both sides of the excision regions 10a ′ and 10a ′. The resin film F adjacent to each of the two regions 20 ′ and 20 ′ is set in the second regions 20 ′ and 20 ′ which are the first inner film portions 20 and 20. Predetermined regions at both ends (the longitudinal direction of the resin film F) Third region 30 second in extension is set to a length corresponding to the amount of area of the film 30, 30) is the second inner film 30, 30 ', 30' are set to. That is, the resin film F includes a pair of second regions 20 ′, 20 ′, a pair of cut regions 20a ′, which become the first inner film portions 20, 20 across the first region 10 ′, which becomes the outer film portion 10. A pair of third regions 30 ′ and 30 ′ to be 20 a and the second inner film portions 30 and 30 are set symmetrically. In the following description, the boundary between the first region 10 ′ and the excision region 10a ′ is referred to as a first boundary L1, the boundary between the excision region 10a ′ and the second region 20 ′ is referred to as a second boundary L2, The boundary between the two regions 20 ′ and the third region 30 ′ is referred to as a third boundary L3.

  And the resin film F which concerns on this embodiment is embossed on one surface E, and the easy peel property (easiness of peeling) is provided (henceforth this surface provided with the easy peel property). Easy peel side). Here, the easy peel property refers to the property of facilitating peeling by weakening the connection strength of the part joined by welding through heat sealing or ultrasonic sealing, or adhesion through an adhesive, and in this embodiment, Easy peel properties are provided on the premise of heat sealing.

  And the provision of the easy peel property to the resin film F is to constitute the resin film F with an easy peel film in which an easy peel layer excellent in the easy peel property (peelability) to the seal is formed on at least one surface E. The surface of the resin film F can be part-coated, or the surface of the resin film F can be roughened.

  In order to produce the cooked rice food packaging material 1 from the resin film F under the above conditions, first, as shown in FIG. 3B, the third regions 30 ′ and 30 ′ at both ends of the resin film F are separated from the third boundary. At L3, it is folded back to the opposite side from the easy peel surface E. Thereafter, as shown in FIG. 3C, the sheet-like food A is disposed on the easy peel surface E side of the first region 10 '.

  Then, as shown in FIG. 3D, the cut region 10a ′ is folded in half so that the first boundary L1 and the second boundary L2 overlap, and the second regions 20 ′ and 20 ′ are folded back to the easy peel surface E side. The third boundary L3 (the bent ridge line L) is brought into a state of being attached to each other. In this state, the easy peel surface E of the first region 10 ′ and the easy peel surface E of the second regions 20 ′ and 20 ′ are opposed to each other, and the easy peel surface E is also opposed to the third boundaries L3 and L3. It will be in the state. Further, the opposite surface of the easy peel surface E of the second regions 20 ′, 20 ′ and the opposite surface of the easy peel surface E of the third regions 30 ′, 30 ′ face each other, that is, the third regions 30 ′, 30. 'Easy peel surface E' faces outward.

  Then, as shown in FIG. 3 (e), the first region 10 ′ and the second region 20 ′ are heat-sealed with a predetermined width in the vicinity of the half-cut resection region 10a ′, and then the resection region 10a ′. Are cut along the first boundary L1 and the second boundary L2. As a result, the divided first region 10 ′ and second regions 20 ′ and 20 ′ are connected by a seal. And the both ends of 1st area | region 10 'which is the transversal direction of the resin film F, and the both ends of each 2nd area | region 20' and 20 'are heat-sealed by predetermined width, and the predetermined width which surrounded the sheet-like food A In addition, the third boundary L3 attached to each other is heat-sealed along the boundary L3 to form a linear seal line SL, and the third boundary L3 is detachably joined.

  Thereby, 1st area | region 10 'becomes the outer film part 10, each 2nd area | region 20', 20 'becomes each 1st inner film part 20, 20, and each 3rd area | region 30', 30 'becomes 2nd. It becomes the inner film part 30,30. Moreover, it will also be in the state by which the both ends of the longitudinal direction of the outer film part 10 and the both ends of the 1st inner film parts 20 and 20 facing this were peeled and sealed.

  As shown in FIGS. 4 to 7, the packaged food 1 for cooked rice food having the above-described configuration is arranged in the longitudinal direction of the outer film portion 10 so that the second inner film portions 30, 30 wrap the cooked rice processed food B inside. The rice cooked food B is packaged by folding it and sealing the ends of the opposing second inner film portions 30 and 30 with each other. That is, the cooked rice processed food packaging material 1 is placed on the pair of second inner film portions 30, 30 with the cooked rice processed food B placed on the pair of second inner film portions 30, 30. The sheet-like food A and cooked rice are folded in half in the longitudinal direction of the film part 10 and heat-sealed so that the opposing ends of the second inner film parts 30 and 30 form a seal line S ′ having a predetermined width. The processed food B is packaged in a separated state. By packaging the cooked rice processed food B in this way, the cooked rice processed food B is packaged with the cooked cooked food packaging material 1 having the above-described configuration.

  And when opening the cooked rice processed food packaging body X, if it pulls so that the front-end | tip part of a pair of 2nd inner film parts 30 and 30 used as the both ends of the packaging material 1 for cooked rice processed foods may be separated, the tensile force will be It acts on the front end side of the first inner film part 20, 20 via the second inner film part 30, 30, and as shown in FIG. 8A, the heat-sealed pair of first inner film parts 20, 20 The tip will peel off. In addition to this, as shown in FIG. 9A, the longitudinal ends of the pair of first inner film portions 20 and 20 sealed by the outer film portion 10 are also centered on the outer film portion 10. It will peel from the side.

  And, as shown in FIG. 8 (b) and FIG. 9 (b), the first inner film portions 20, 20 and the second inner film portions 30, 30 are pulled by the pulling action on the second inner film portions 30, 30. While the bent ridge line L at the boundary is shifted from the distal end side of the first inner film portion 20, 20 to the proximal end side, the distal end side of the first inner film portion 20, 20 is drawn to the second inner film portion 30, 30. Will be pulled out.

  Thus, a space | interval between a pair of 1st inner film parts 20 and 20 spreads by drawing a pair of 1st inner film parts 20 and 20 outside, and it is a sheet form in the area | region in which the cooked rice processed food B was accommodated. Food A will be exposed. And as shown in Drawing 8 (c), Drawing 9 (c), and Drawing 10 (a), between the cooked rice processed food B and sheet-like food A to the 1st inner film parts 20 and 20 near the base end part When pulled out, the sheet-shaped food A and the cooked rice processed food B are integrated, and further, the base end portions of the first inner film portions 20 and 20 are peeled off from the side end portions of the outer film portion 10 by pulling. .

  Then, as shown in FIG. 10 (b), the first inner film portions 20, 20 and the second inner film portions 30, 30 are separated from the outer film portion 10, and the remaining outer film as shown in FIG. 10 (c). It will be in the state which wrapped the cooked rice processed food B integrated with the sheet-like food A in the state in which the part 10 was folded in half. Thereby, the cooked rice processed food A integrated with the sheet-like food B can be grasped by hand through the outer film part 10, and the cooked cooked rice A can be eaten hygienically even if the hands are dirty. it can.

  As described above, the rice cooked food packaging material 1 according to the present embodiment is simply processed by pulling both ends of the second inner film portions 30 and 30 away from the state in which the cooked rice processed food B is packaged. The sheet-like food A and the cooked rice processed food B separated from the food B can be integrated, and further, the cooked rice processed food B integrated with the sheet-like food A can be grasped by the outer film portion 10. Can be in a state.

  And the edge part of the 2nd inner film part 30 and 30 hold | grips at the time of opening by extending the front-end | tip part of the 2nd inner film part 30 and 30 outside the base end of the 1st inner film part 20 and 20 Easy to open and easier to open.

  Furthermore, since the embossing was performed on the surface of the pair of second inner film portions 30 and 30 facing the cooked rice processed food B, the resistance between the second inner film portions 30 and 30 and the cooked rice processed food B generated at the time of opening. Can be easily opened without causing the cooked rice processed food B to lose its shape.

  Moreover, since the front-end | tip parts of a pair of 1st inner film parts 20 and 20 are heat-sealed so that peeling is possible, the water | moisture content of the cooked rice processed food B is the 1st inner film part 20 in the state which packaged the cooked rice processed food B. , 20 can be prevented from reaching the sheet-like food A. Thereby, it can package, without harming the food texture of the sheet-like food A.

  And the outer film part 10, the 1st inner film parts 20 and 20, and the 2nd inner film parts 30 and 30 are formed by performing a bending process, a sealing process, and a cutting process with respect to the resin film F of 1 sheet. Therefore, it can be manufactured easily.

  In addition, the packaging material for cooked rice processed foods of this invention is not limited to the said embodiment, Of course, a various change can be added in the range which does not deviate from the summary of this invention.

  In the above embodiment, the outer film part 10, the pair of first inner film parts 20, 20, and the second inner film parts 30, 30 are formed from a single resin film F. However, the present invention is not limited to this. For example, the outer film portion 10 or the like may be formed by connecting a plurality of film pieces having a sheet shape.

  Specifically, as shown in FIG. 11, resin films Fa and Fb folded in two so as to form a first inner film portion 20 and a second inner film portion 30 connected via a bent ridge line L are formed. Two sheets are produced, and the two resin films Fa and Fb are arranged so that the respective bent ridge lines L are associated with each other, and one piece of each resin film Fa and Fb (corresponding to the first inner film portion 20). A rectangular resin film Fc that becomes the outer film portion 10 is overlaid on the sheet-like food A, and one piece and the resin film Fc that becomes the outer film portion 10 can be peeled so as to surround the sheet-like food A You may make it heat-seal. This kind of packaged food for cooked rice is generally printed on the outer film part 10 with a product name, product image, etc., but the product specifications are changed (for example, in the cooked rice processed food B). The contents of the printing may be changed due to changes in price and price, etc., and when changing the contents of printing, the entire cooked rice packaging material printed with the contents before the change must be discarded. There is a case. However, as described above, if the outer film unit 10 to be printed is configured separately and independently, it is only necessary to print or discard only the outer film unit 10 even if the printing is changed. Can be minimized.

  Moreover, in the said embodiment, the outer film part 10 and the 1st film part 20 and 20 were sealed so that peeling was possible by predetermined width, and it enabled it to isolate | separate the 1st film part 20 and 20 from the outer film part 10 at the time of opening. However, for example, the outer film part 10, the first inner film parts 20 and 20, and the second inner film parts 30 and 30 are continuously formed by bending a single film, and the outer film part 10 and the first film A cutting auxiliary line (for example, a perforation or a half cut) is provided at the boundary between the inner film parts 20 and 20, and the outer film part 10 and the first inner film parts 20 and 20 May be separable.

  Even if it does in this way, the 1st inner film parts 20 and 20 can be separated from the outer film part 10, and there can exist an effect | action and effect similar to the said embodiment. In this case, in order to enable smooth cutting with the auxiliary cutting line, the outer film part 10 is at least at one end (one end of the auxiliary cutting line) in one direction of the outer film part 10. It is preferable to provide a notch or a notch on the boundary between the first film portion 20 and the first film portion 20. In this case, since the outer film portion 10 and the first inner film portions 20 and 20 are already connected, the side end portions of the outer film portion 10 and the proximal ends of the first inner film portions 20 and 20 are not necessarily provided. Needless to say, it is not necessary to heat-seal the parts with a predetermined width.

  Further, the base end portion of the first inner film portion 20 is firmly sealed to the side end portion of the outer film portion 10, and the cutting auxiliary line as described above is provided near the seal portion in the outer film portion 10 or the first inner film portion 20. May be provided. Even if it does in this way, since the 1st inner film part 20 can be parted (separated) with an auxiliary cutting line with respect to the outer film part 10 at the time of opening, there can exist an effect similar to the said embodiment. However, in this case, since the manufacturing cost tends to increase due to the sealing of the film and the processing of the auxiliary cutting line for the film, the outer film portion 10 and the first film portions 20 and 20 can be peeled with a predetermined width. The outer film part 10, the first inner film part 20, 20 and the second inner film part 30, 30 are formed by bending a single film as described above to form the outer film part 10, It is preferable to provide a cutting auxiliary line (for example, perforation or half cut) at the boundary between the first inner film portions 20 and 20. Further, considering the ease of opening (separability of the first inner film portion 20 with respect to the outer film portion 10), the side end portion of the outer film portion 10 and the base end portions of the first film portions 20 and 20 are predetermined. It is more preferable to seal the width so as to be peelable.

  In the above-described embodiment, the ends of the pair of first inner film portions 20 and 20 are heat-sealed so as to be peelable from each other. However, the present invention is not limited to this. Also good. However, in order to reliably prevent the moisture of the cooked rice processed food B from reaching the sheet-shaped food A, it is preferable to heat-seal the tips as in the above embodiment.

  In the said embodiment, although comprised so that the front-end | tip part of the 2nd inner film parts 30 and 30 might extend outside rather than the base end of the 1st inner film parts 20 and 20, it is not limited to this, For example, the distal ends of the second inner film portions 30, 30 may coincide with the proximal ends of the first inner film portions 20, 20, or may be positioned inside the proximal ends of the first inner film portions 20, 20. Good. However, in consideration of operability at the time of opening, it is preferable that the distal end portion of the second inner film portion 30, 30 is positioned outside the base end of the first inner film portion 20, 20 as in the above embodiment. Needless to say.

  In the embodiment described above, the resin film F provided with easy peelability is adopted on the entire surface of one side in consideration of peelability at the time of opening. You may make it provide easy peel property only to the area | region requested | required.

  In the above embodiment, the side end portion of the outer film portion 10 and the base end portion of the first inner film portion 20 are sealed in a peelable manner so as to form a seal line (band-shaped seal line) S having a predetermined width. For example, the edge of the seal line on the center side in the width direction of the outer film portion 10 is formed in a sawtooth shape or a wavy line shape, or the side end of the outer film portion 10 and the base end of the first inner film portion 20 are sawn. It may be fused or sealed in a blade shape or a wavy shape. In this way, when the second inner film portion 30 is pulled to separate (separate) the base end portion of the first inner film portion 20 from the side end portion of the outer film portion 10, the pulling force is applied to the seal line. Since it acts on the several vertex formed on an edge intensively, the 1st inner film part 20 can be smoothly peeled (separated) from the outer film part 10 from each vertex.

  In the above-described embodiment, the outer film portion 10 is formed in a rectangular shape in plan view, and the longitudinal direction of the outer film portion 10 is set as one direction and is folded in half in the longitudinal direction of the outer film portion 10 during packaging. It is not limited, What is necessary is just to change suitably according to the response | compatibility of the cooked rice processed food B to package. That is, the outer film part 10 should just be formed in the planar view square shape, for example, when the cooked rice processed food B is formed in the rod shape, the outer film part 10 is made into the substantially square shape in the plan view. Forming a pair of first inner film portions 20, 20 and a pair of second inner film portions 30, 30 with the other direction orthogonal to one direction as the width direction, and folding in half in one direction during packaging It may be.
