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

  FIG. 1 is a perspective view showing an example of a web corner paper container according to the present invention, and this web corner paper container is formed by assembling a blank shown in FIG.

  The blank in FIG. 2 is a paperboard with a resin film bonded to the entire surface, and is made by punching out a material that has been subjected to predetermined printing in a multi-faceted state. A front side plate 2, a rear side plate 3, a left side plate 4 and a right side plate 5 are connected to the rectangular bottom plate 1 in front, rear, left and right via folding lines a to d, respectively. Are connected to each other via a fold line f of radiation extending outward from the corner of the bottom plate, and a web corner. Part W is formed.

  A lid plate 6 is connected to the upper side of the rear side plate 3 via a fold line g, and a flap 7 is connected to the upper side of the rear plate 3 via a fold line h. Is provided with a locking piece 6a protruding from the center of the tip via a fold line i, and a notch α for inserting the locking piece 6a is provided at the center of the fold line h where the flap 7 is connected. . The fold line i of the locking piece 6a has a notch β for facilitating the bending, and notches 6b are formed on the left and right sides of the lid plate 6.

  The left side plate 4 and the right side plate 5 are respectively provided with handle plates 8 and 9 connected to the upper side of the left side plate 4 and the right side plate 5 via a fold line j, and the handle plates 8 and 9 are formed with a fold line k for folding in half. In addition, locking inserts 8a and 9a project from the ends of the grip plates 8 and 9 via folding lines l, respectively. In this example, V-shaped cutouts are formed at the bases of the insertion pieces 8a and 9a, and when used, these insertion pieces 8a and 9a are respectively provided with the cutouts 6b on the left and right sides of the lid plate 6 described above. It is designed to engage.

  Moreover, in this blank, three longitudinal ruled lines are formed in the middle of the front side plate 2 and the rear side plate 3 to prevent bending. The fold lines a to l may be basically formed by pushing rules, but the fold line g of the cover plate 6, the fold line h of the flap 7, the fold lines j of the handle plates 8 and 9, and the handle plate Regarding the fold line k for folding the halves 8 and 9 and the fold line 1 of the insertion pieces 8a and 9a, in consideration of the ease of folding the fold line portion when designing the blank, 1) A so-called lead ruler with a notch, 2) a perforation with a large pitch, 3) a perforation with a small pitch, or the like may be employed as appropriate.

  To assemble the blank shown in FIG. 2, first, the side plates 2 to 5 are erected with respect to the bottom plate 1, and at the same time, the folded pieces 2a to 5a are pulled out and folded to form the web corner portion W. A box shape as shown in FIG. 3 is obtained by pasting the web corner portion W on the outside of the left side plate 4 and the right side plate 5 in a folded state. In the state where the blank is assembled in this way, the upper opening is in a state of being slightly curved outward and expanded due to the repulsive force against the bending of the paperboard. Then, a plurality of assembled products shown in FIG. 3 are stacked and supplied to the filling process.

  In the filling step, the contents shown in FIG. 3 are put in from the top, the left and right grip plates 8 and 9 are folded inward, the flap 7 is folded inward, and then the cover plate 6 is covered. Then, the locking piece 6a at the tip of the lid plate 6 is folded and inserted into the notch α at the base of the flap 7, so that the lid plate 6 covers the lid 7 as shown in FIG.

  The web corner paper container of FIG. 1 is finally commercialized with a shrink film as needed. The contents include foods and seasonings that are cooked by a microwave oven, and those containing these are sold as products at the store.

  When cooking with a microwave oven, the lid plate 6 is opened and the left and right handle plates 8 and 9 are widened to take out the seasonings and ingredients inside the container. And after putting the seasoning etc. which were taken out into a container with ingredients (If only seasonings are stored, ingredients are prepared separately), the left and right grip plates 8 and 9 are exposed to the outside, and the flap 7 Is folded inward and covered with a cover plate 6 from above, and then, as shown in FIG. 4, the left and right handle plates 8 and 9 are folded inward, and the insertion piece at the tip is 8a and 9a are inserted into the gaps formed by the notches 6b on the left and right ends of the lid plate 6. In this way, by locking the insertion pieces 8a and 9a at the tips of the left and right grip plates 8 and 9 to the sides of the lid plate 6, the lid plate 6 is prevented from being lifted and folded in half. The left and right handle plates 8 and 9 serve as handles.

  The web corner paper container of FIG. 1 is put into a microwave oven and cooked after being used as shown in FIG. At this time, since the height of the entire container is not so high, it is not difficult to put it in and out. When steam is generated by cooking, the left and right handle plates 8 and 9 that are folded in half suppress the lifting of the cover plate 6, so that the steaming effect required for the range container is not impaired. Furthermore, since the left and right handle plates 8 and 9 that are folded in half become the handle after cooking, it is possible to take out from the interior with confidence by having a folded portion that does not directly transmit this heat.

  FIG. 5 is a perspective view showing a modified example of the web corner type paper container according to the present invention, and this web corner type paper container is formed by assembling a blank whose development is shown in FIG. Since the blank shown in FIG. 6 has substantially the same shape as the blank of FIG. 2, the same reference numerals are given to portions having the same configuration, and description thereof is omitted.

  The web corner type paper container of FIG. 5 is obtained by changing the locking means of the left and right grip plates 8 and 9 in the web corner type paper container shown in FIG. That is, in the blank of FIG. 6, the extension pieces 10 and 11 are provided through the fold line l in place of the insertion pieces 8 a and 9 a protruding from the tips of the handle plates 8 and 9, respectively. By forming a U-shaped notch γ at the center of l, convex portions are formed at the tips of the grip plates 8 and 9 when the extension pieces 10 and 11 are bent. And the notch 6c of the size corresponding to this convex part is formed in the both sides of the cover board 6. FIG.

  The blank shown in FIG. 6 is assembled in the same manner as the blank shown in FIG. 2, and the web corner portion W is formed by the same procedure, and the web corner portion W is folded to the outside of the left side plate 4 and the right side plate 5. By bonding, a box shape as shown in FIG. 7 is obtained. Then, a plurality of assembled products shown in FIG. 7 are stacked and supplied to the filling process.

  In the filling step, the contents shown in FIG. 7 are put in from the top, the left and right grip plates 8 and 9 are folded inward, the flap 7 is folded inward, and the cover plate 6 is covered. Then, the locking piece 6a at the tip of the lid plate 6 is folded and inserted into the notch α at the base of the flap 7, so that the lid plate 6 covers the lid as shown in FIG.

  When cooking with a microwave oven, the lid plate 6 is opened and the left and right handle plates 8 and 9 are widened to take out the seasonings and ingredients inside the container. And after putting the seasoning etc. which were taken out into a container with ingredients (If only seasonings are stored, ingredients are prepared separately), the left and right grip plates 8 and 9 are exposed to the outside, and the flap 7 Is folded inward and covered with a cover plate 6, and then the left and right handle plates 8 and 9 are folded inward, as shown in FIG. 10 and 11 are folded outwardly, and the convex portion formed by the cut γ is inserted into the gap formed by the notches 6 c at the left and right ends of the cover plate 6. In this manner, the protrusions 10 and 11 at the tips of the left and right grip plates 8 and 9 are folded outwardly, and the convex portion formed by the cut γ is locked to the side of the lid plate 6 to thereby close the lid. The lift of the plate 6 is stopped, and the left and right handle plates 8 and 9 which are folded in two serve as the handle.

  The web corner paper container of FIG. 5 is cooked in a microwave oven after the usage pattern shown in FIG. At this time, since the height of the entire container is not so high, it is not difficult to put it in and out. When steam is generated by cooking, the left and right grip plates 8 and 9 and their extension pieces 10 and 11 suppress the lifting of the cover plate 6, thereby impairing the steaming effect required for the range container. There is nothing. Furthermore, since the left and right handle plates 8 and 9 that are folded in half become the handle after cooking, it is possible to take out from the interior with confidence by having a folded portion that does not directly transmit this heat.

  Moreover, the web corner type | mold paper container of FIG. 5 can also be made into the usage form as shown in FIG. In this case, as a procedure, after putting seasonings and the like into the container together with the ingredients, the left and right handle plates 8 and 9 are exposed to the outside, the flap 7 is folded inward, and the lid plate 6 is covered from above. However, after that, the extension pieces 10 and 11 at the tips of the left and right grip plates are folded back inward, and the left and right handle plates 8 and 9 are folded with the extension pieces 10 and 11 folded. Each is folded inwardly, and the convex portion by the notch γ is inserted into the gap by the notches 6 c at the left and right ends of the cover plate 6. In this manner, by lifting the extension pieces 10 and 11 and folding the handle plates 8 and 9 in two, the raised portion of the notch γ is locked to the side of the lid plate 6 to prevent the lid plate 6 from lifting up. At the same time, the left and right handle plates 8 and 9 folded in half serve as the handle.

  In the web corner type paper container in the state of use shown in FIG. 9, when steam is generated by cooking, the left and right handle plates 8 and 9 and their extension pieces 10 and 11 are lifted by the lid plate 6. Therefore, the steaming effect required for the range container is not impaired. Furthermore, since the left and right handle plates 8 and 9 are folded into two handles after cooking, they can be taken out of the cabinet with a sense of security by having a portion where this heat is not directly transmitted. At this time, as can be seen with reference to FIG. 10, the handle plates 8, 9 are folded in two by folding the extension pieces 10, 11, so that steam generated during cooking is entered into the handle plates 8, 9. Since it is prevented, it does not become hot.

  As mentioned above, the embodiment of the present invention has been described in detail by giving two examples. However, the web corner type paper container according to the present invention is not limited to the above embodiment, and the gist of the present invention is described. Naturally, various changes can be made without departing from the scope.

  For example, in the above example, a paperboard with a resin film bonded to the entire surface was used as the material of the container. However, a resin such as polypropylene, polyethylene, polyethylene terephthalate, polybutylene terephthalate, or the like, may be used for paperboard paperboard. A paperboard appropriately laminated with a film may be used. Further, instead of paperboard, corrugated cardboard sheets with fine corrugations (microflutes) can be used.

  In the above example, the overall shape of the container is rectangular, and the web corner portion is bonded to the short side. However, the overall shape may be a square as long as it is rectangular, or the web corner portion. As for, it is only necessary to determine which of the short side and the long side is bonded according to the container design.

  The web corner paper container of the present invention is preferably used to contain food for cooking in a microwave oven. And in addition to the type of products that are taken out of the bag and cooked in the bag, only the seasoning is put in, and the type of product that is cooked together with ingredients such as eggs, tofu and meat prepared separately Also suitable.
