  The present invention belongs to the technical field of cartons for storing foods and the like, and more specifically, for storing processed foods and the like so that they can be cooked and eaten in a microwave oven without being transferred to other containers. The present invention relates to a microwave oven carton and a package using the carton.

  Conventionally, as a processed food cooked in a microwave oven, a set product is known that combines a bowl-shaped container containing rice to be cooked and a packaging bag containing ingredients to be cooked. The box-shaped container and packaging bag of this set product are sold together in one carton. As this type of carton, a box-shaped one is usually used, but recently, a sleeve-type one as described in Patent Document 1 is also used.

  The sleeve-type carton described in Patent Document 1 has a seat portion that holds the bottom of the bowl-shaped container, and one end connected to the seat section and straddles the upper side of the bowl-shaped container, and the other end can be engaged with and disengaged from the seat section. The seat portion is a two-stage plate material having a bottom plate facing the bottom of the bowl-shaped container and a holding plate having an opening for holding the container body of the bowl-shaped container. The bowl-shaped container held in this seat is stable, without rotating, falling off, or slipping, even when handled by ordinary buyers. The product form can be kept in a good state.

  In this sleeve type carton, the set product described above, that is, a bowl-like container containing rice to be cooked and sealed with a lid, and a packaging bag containing ingredients to be cooked in a stacked state are stored and packaged. The body is formed. This package is offered for sale at the store, but it becomes conspicuous when it is displayed side by side with the curved portion up, and exhibits a sales promotion effect.

  The procedure of cooking with a microwave oven using this package is as follows. First, open the cover of the sleeve-type carton, open a part of the lid of the bowl-shaped container, open the packaging bag, and open the packaging bag side from the opening formed by covering the lid. Put in a container and combine with rice. Next, the lid member is returned to close the opening, and the cover part is returned to lock the tip of the cover part to the seat part. And the package which became the combination of a sleeve type carton and a bowl-shaped container is put in the store | warehouse | chamber of a microwave oven with the cover part covered, and cooking with a microwave oven is performed. At this time, food that has been micro-irradiated may suddenly boil, but since the opening of the lid material is suppressed by closing the cover part and the upper part of the bowl-shaped container is covered by the cover part, There is no splash of food from inside the container to the outside of the package, and the inside of the microwave oven is not soiled. When the heating is completed, the package is taken out of the microwave oven, the carton cover is opened, the lid of the bowl-like container is removed, and the contents are eaten.

Japanese Patent Laid-Open No. 2004-256170

  The sleeve-type carton described in the above-mentioned Patent Document 1 has a seat portion composed of two upper and lower plate members, and thereby the bowl-shaped container is held and stabilized. Providing such a seat increases the amount of paper used to assemble the carton. For this reason, there is a problem that the number of blanks that can be taken from the packaging material is reduced and the cost is high. That is, since such packaging cartons are manufactured in large quantities, even if there is a slight difference in cost for a single blank, the overall difference in material costs is large.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to make it possible to exhibit an appearance with a curved portion while having a function of holding a stored bowl-shaped container. On the other hand, an object of the present invention is to provide a microwave oven cooking carton that reduces the amount of paper used to reduce costs, and also provides a package using the same.

  In order to achieve the above object, the microwave oven cooking carton of the present invention is a carton formed by assembling a single blank, and the bottom plate, the top plate, and the pair of side plates have a rectangular tubular body. In the state that the rear part of the body part is closed and the closed part is formed, the container is configured to store the bowl-like container, and the bottom plate is sized to protrude forward from the top plate. A presser plate that is folded forward and engages with the flange of the bowl-shaped container accommodated at the front end edge thereof to prevent its jumping out is straddled, and the folded back presser plate is straddled in front of the top plate. In this state, a cover plate whose tip can be locked to the bottom plate is connected.

  Moreover, the packaging body of the present invention is a packaging body using the above-mentioned microwave oven cooking carton, and a bowl-shaped container is housed in a rectangular tube-shaped trunk formed by a bottom plate, a top plate, and a pair of side plates. A presser plate that is folded back and engages with the flange of the bowl-shaped container is connected to the front of the bottom plate, and the folded presser plate is straddled to the front of the top plate And a cover plate whose tip is locked to the bottom plate is connected.

  Moreover, the packaging body of the present invention is a packaging body using the above-mentioned microwave oven cooking carton, and a bowl-shaped container is housed in a rectangular tube-shaped trunk formed by a bottom plate, a top plate, and a pair of side plates. And a packaging bag is placed on the bowl-shaped container, and a press plate that is folded back and engages with the flange of the bowl-shaped container is provided in front of the bottom plate. A cover plate whose front end is locked to the bottom plate in a state of straddling the folded presser plate is provided in front of the cover plate.

  The microwave oven cooking carton according to the present invention prevents the movement of the bowl-shaped container in the carton during cooking by folding the presser plate connected to the bottom plate and engaging the tip with the flange of the bowl-shaped container. Therefore, compared to the conventional carton that holds the bowl-shaped container by the seat portion made of two-stage upper and lower plate materials, the amount of paper used is reduced, so the material cost can be reduced and the cost can be reduced. . Moreover, since the cover plate can have an appearance with a curved portion, it can be made the same as the conventional one in that a sales promotion effect is obtained by making it stand out at the store.

  The packaging body of the present invention prevents the movement of the bowl-shaped container in the carton during cooking by pressing the flange of the bowl-shaped container stored in the body of the carton with the tip of the press plate continuously provided on the bottom plate. As a result, the amount of paper used to assemble the carton is reduced compared to the conventional carton that holds the bowl-shaped container with a seat consisting of two-stage upper and lower plate materials. The total cost can be reduced. And since the assembled package can be made to have an appearance with a curved portion, it can be made the same as the conventional one in that a sales promotion effect is obtained by making it stand out at the store.

It is a perspective view which shows an example of the package using the carton for microwave oven cooking which concerns on this invention. It is an expanded view of the blank which assembles the microwave oven cooking carton used with the package of FIG. It is a perspective view which shows the state which put the bowl-shaped container and the packaging bag in the carton. It is explanatory drawing which shows a mode that a bowl-shaped container is returned to a carton. It is explanatory drawing which shows a mode that the convex part of the presser plate was engaged with the bowl-shaped container returned to the carton. It is a perspective view which shows another example of the package body using the microwave oven cooking carton which concerns on this invention.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  The package shown in FIG. 1 uses a carton A in which a blank shown in a developed view in FIG. 2 is assembled, and stores a combination product of a bowl-shaped container B and a packaging bag C therein.

  The bowl-shaped container B to be put in the package contains food that has been pre-processed so that it can be cooked in a microwave oven, such as rice. For example, the food is put in a circular container body, and the flange The lid is closed by heat sealing or the like. On the other hand, the packaging bag C stored in the carton in combination with the bowl-shaped container B contains ingredients that can be cooked and cooked together with the food stored in the bowl-shaped container B. It is packaged using a seal bag. Note that the shape of the bowl-shaped container B is not limited to a circle, and the packaging bag C only needs to be substantially flat as a whole, and the form and packaging material are not particularly limited. Further, in the case of a product in which only the food contained in the bowl-shaped container B is cooked, the packaging bag C is unnecessary, and only the bowl-shaped container B is stored in the carton A.

  The blank forming the carton A is formed by punching paperboard. As shown in FIG. 2, the bottom plate 1, the side plate 2, the top plate 3, and the side plate 4 are arranged in the horizontal direction in this order, and the bottom plate 1 The paste margin piece 5 is continuously provided on the opposite side. The bottom plate 1, the side plate 2, the top plate 3, and the side plate 4 have lower sides that are substantially in a straight line, and the bottom plate 1 and the lower side of the top plate 3 are provided with closing plates 6 and 7, respectively. Are respectively provided with folding pieces 8 and 9. And in order to set it as an automatic lock | rock, the folding | turning parts 6a and 7a are divided by the closing rules 6 and 7 by the lead rule.

  The bottom plate 1 has a rectangular shape that is slightly longer in the vertical direction, while the top plate 3 is shorter in the vertical direction than the bottom plate 1 as shown in the figure. As a result, the bottom plate 1 protrudes forward from the top plate 3 during assembly. It is a size. In addition, a leaf-like bent piece 10 is continuously provided on one side plate 2 via a curved fold line a that connects the front ends of the bottom plate 1 and the top plate 3 to each other. 4 also has a leaf-like bent piece 11 of the same tree connected continuously through a bent line b symmetrical to the side plate 2.

  In this blank, the side plate 2 is provided with a leaf-shaped ventilation hole 2a in consideration of the design, but the shape of the ventilation hole is not limited to the illustrated one. Further, such a vent may be provided as necessary, and may be provided on both side plates 2 and 4, for example, or may not be provided.

  On the upper side of the bottom plate 1, a presser plate 12 having a size in which the length in the vertical direction is slightly larger than the width of the side plates 2 and 4 is connected so as to be foldable. It is a shape having a forked portion 12a by being recessed in the bottom of the pot, and both sides are recessed in an arc shape in accordance with the shape of the bent pieces 10 and 11 of the side plates 2 and 4. On the other hand, a cover plate 13 having a size in which the length in the vertical direction is larger than the width of the side plates 2 and 4 and larger than the length in the vertical direction of the presser plate 12 is disposed above the top plate 3 via the hinge portion α. In this example, the hinge portion α is formed by a normal stamp or lead rule.

  An insertion piece 14 is connected to the front end of the cover plate 13 so that it can be bent, and the insertion piece 14 is inserted and locked at the boundary between the bottom plate 1 and the holding plate 12 during assembly. A slit c is formed with such a length that can be formed, and a finger-tip-sized drawing hole 15 is formed in the center of the slit c.

  The container shown in FIG. 1 is formed by storing the container B and the packaging bag C in the carton A for assembling the blank shown in FIG. 2, but as a first step, the blank shown in FIG. To supply. Specifically, in a state in which the folded portions 6a and 7a of the closing plates 6 and 7 are folded, the closing plates 6 and 7 and the folded pieces 8 and 9 are folded inward, and the folded portions 6a and 6a, While the back side of 7a is glued, the sack pasting the paste margin piece 5 to the side plate 4 is pasted. A plurality of blanks folded in the sack pasting state are sent together to the filling step, and the package shown in FIG.

  In the filling process, when a blank folded with a sack applied is raised, the bottom plate 1, the top plate 3, and the pair of side plates 2 and 4 form a square cylindrical body, and the closure plates 6 and 7 are auto-locked. Then, the rear part is closed to form a closed part. In addition, this closing part is only an example, and other than such an auto bottom, closing means such as an insertion tongue, a seal sack, and a lock sack may be adopted.

  After opening in this way, as shown in FIG. 3, the bowl-like container B and the packaging bag C in a state of being stacked from the front of the carton are put, and the presser plate 12 continuously provided in front of the bottom plate 1 is folded back. At this time, the presser plate 12 does not have to be engaged with the flange of the bowl-shaped container B, and may be engaged when cooking after heating. In FIG. 3, in order to make the bowl-shaped container B and the packaging bag C easier to see, the cover plate 13 connected to the top plate 3 is shown in a raised state. The container B and the packaging bag C are inserted into the carton A without being lifted.

  Next, the leaf-like bent pieces 10 and 11 connected in front of the side plates 2 and 4 are bent inward at the folding lines a and b, respectively, so that the portions along the folding lines a and b are moved up and down. Let it be in a stretched state. Finally, the insertion piece 14 at the tip of the cover plate 13 provided in front of the top plate 3 is inserted into the slit c at the boundary between the bottom plate 1 and the top plate 3 and locked. As a result, the cover plate 13 is in the state shown in FIG. 1 in which the front end is locked to the bottom plate 1 while straddling the presser plate 12 in a curved state. In this embodiment, the size of the cover plate 13 is increased so as to be curved outward, but it may be straight.

  The package shown in FIG. 1 cooks the contents in a microwave oven, and the procedure is as follows. First, the curved cover plate 13 is lifted to open the front part of the carton A. At this time, it is preferable that the fingertip is applied to the insertion piece 14 from the extraction hole 15 in the center of the slit c, and the cover plate 13 is opened while the insertion piece 14 is pulled out from the slit c. In this way, the cover plate 13 is opened, and the bowl-like container B and the packaging bag C are taken out from the front part of the carton A.

  After the bowl-shaped container B and the packaging bag C are taken out, a part of the lid of the bowl-shaped container B is opened and opened, and the packaging bag C is opened. Into a bowl-shaped container B and combine with rice. Next, as shown in FIG. 4, the bowl-like container B with the cover closed and the opening closed is returned into the carton A and pushed into the back, and then the presser plate 12 is moved as shown in FIG. 5. The bifurcated convex portion 12a is folded and engaged under the flange of the bowl-shaped container B, and the bowl-shaped container B is fixed in the carton A. The cover plate 13 may be left open.

  And the packaging body which accommodates the bowl-shaped container B in the carton A is put in the store | warehouse | chamber of a microwave oven, and heat cooking by a microwave oven is performed. At this time, there is a possibility that the micro-irradiated food may bump, but the bowl-like container B with the lid member returned is prevented from moving by the presser plate 12 and the top board 3 covers the upper part of the bowl-like container B. Therefore, the splash of food does not fly from the inside of the bowl-shaped container B to the outside of the package, and the inside of the microwave oven is not soiled. When the heating is completed, the package is taken out from the inside of the microwave oven, the presser plate 12 is removed from the flange, the bowl-like container B is taken out from the carton, the lid material is removed, and the contents are eaten.

  The carton A is placed flat when in use, but can be put up with the closed rear part down, so that the curved cover plate 13 part stands out and stands out at the store. It is easy to be noticed by consumers at the time of display, and the effect of promoting sales is demonstrated.

  In the carton A, the leaf-like folding pieces 10 and 11 connected in front of the side plates 2 and 4 are folded inward at the folding lines a and b, so that the folding lines a and b are formed. Since the extending portion is stretched up and down, strength is exerted when the bottom plate 1 and the top plate 3 facing each other are pushed, so that there is no problem that the cartons are crushed when stacked in a flat state.

  The package shown in FIG. 6 has substantially the same configuration as that of FIG. 1, but only the configuration of the hinge part α between the top plate 3 and the cover plate 13 is changed.

  As shown in the figure, the hinge portion α has a configuration in which a plurality of fold-like cuts are intermittently arranged. When the cover plate 13 is lifted with the hinge portion α as a boundary, adjacent cuts are formed. The paperboard is bent so that the tissue destruction of the paperboard gradually increases from the vicinity of the center of the imaginary line connecting the opposite ends toward the end of the cut. Therefore, when the cover plate 13 is lifted, the portion near the edge of the cut becomes larger in the destruction of the paperboard, but the portion near the center of the imaginary line connecting the opposite ends of the adjacent cuts is connected in a smaller amount. Therefore, the repulsive force at the time of bending becomes small. Therefore, when the contents of the carton A are taken in and out, the cover plate 13 can be held in an open state.

  As mentioned above, although the form for implementing this invention has been demonstrated in detail, the carton for microwave oven cooking by this invention and the package using the same are not limited to said form at all, Of course, various changes can be made without departing from the spirit of the invention.
