  There are various ways to use the pillow type carton as described above. For example, in fast food etc., if the contents (solid, granular) and topping (powder, granular) are put and rotated or shaken, the arched ceiling Since the contents easily roll along the surface and bottom, compared to a square carton, the topping can be attached to the contents evenly. In consideration of such usage, it is preferable that the product is stable in a state where it is placed on a sales stand or a table when displayed at a store or when a customer eats. However, the conventional pillow type carton has a problem that when placed on a flat place, the arch-shaped bottom surface is grounded and is not stable.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a pillow-type carton that can be stably placed on a flat place.

  In order to achieve the above object, the pillow-type carton of the present invention includes a trunk portion composed of a front panel, a top panel, a back panel, and a bottom panel, and inwardly bent fold lines on both sides of the top panel. A side outer panel that is connected to each other through a side wall, and a side inner panel that is connected to both sides of the bottom panel via an inwardly curved fold line. A recess is formed in a shape that is cut away, leaving an insertion piece at the bottom portion of the recess, and a slit corresponding to the insertion piece is formed in the center on the side inner panel, The top panel and the bottom panel are bent by bending the side inner panel and overlapping the side outer panel from above, inserting the insertion piece into the slit, and closing both sides of the body sequentially. With the lower two surfaces is in arched, in both sides of the body portion, characterized in that the legs of the side outer panel forms a foot back and forth.

  In the pillow type carton, it is preferable that a zipper for opening is provided from the front panel to the top panel.

  In the pillow type carton, each corner is preferably a web corner.

  In the assembled state, the pillow-type carton of the present invention has a curved shape with the top and bottom surfaces curved by the curved top and bottom panels, respectively. Since the foot is grounded, the carton itself is prevented from swinging, and can be stably placed on a flat place.

  And since there is a zipper for opening from the front panel to the top panel, it can be easily opened and placed on a table or the like with the upper part opened.

  Moreover, since each corner is a web corner, the contents are prevented from leaking outside.

It is a perspective view showing an example of a pillow type carton according to the present invention. It is an expanded view of the blank which forms the carton of FIG. It is a top view shown in the state which stuck the blank of FIG. It is a perspective view which shows the carton of FIG. 1 in the state which raised the display piece.

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

  The pillow type carton C shown in FIG. 1 is formed by assembling a single blank B shown in FIG. 2 formed by punching a paperboard for paper containers. The carton C described in this example is used in fast food, and is filled with contents (solid, granular) and topping (powder, granular) at the store.

  In the blank B, as shown in FIG. 2, the front panel 11, the top panel 12, the back panel 13, the bottom panel 14 and the glue allowance panel 15 are arranged in this order via parallel folding lines a, b, c and d. The side outer panel 16 is connected to both sides of the top panel 12 via an inwardly curved (arc-shaped) fold line e, and inwardly curved to both sides of the bottom panel 14 respectively. A side inner panel 17 is continuously provided via a polygonal (arc-shaped) broken line f.

  The side inner panel 17 on both sides of the bottom panel 14 has a curved shape with the outer edge facing away from the inner folding line f, and has a shape in which the middle swells as shown. Further, triangular folding pieces 17a are connected to both sides of each side inner panel 17 via a fold line g, and both sides of the back panel 13 and the glue margin panel 15 are respectively connected to fold lines h and i. Triangular folding pieces 13a and 15a are connected in series, and adjacent folding pieces, that is, the folding piece 13a and the folding piece 17a are radial perforations α, and the folding pieces 15a and 17a are radial perforations β, respectively. The triangular part which consists of these adjacent folding pieces comprises the web corner part. Note that the folding pieces 13a on both side pieces of the back panel 13 are provided via so-called lead rules in which pressing and cutting are provided alternately.

  The side surface outer panel 16 on both sides of the top panel 12 is formed with a recess 16b cut out in a trapezoidal shape with the legs 16a at both ends, and a foldable insertion at the bottom of the recess 16b. A piece 16c is provided, and an insertion slit 17b having both ends curved and having a notch in the middle is formed at the center of the side inner panel 17 corresponding to the insertion piece 16c. Further, in this blank B, two display pieces 16 d that can be raised are partitioned on each side outer panel 16.

  The front panel 11 is formed with a knob portion 11a at the center of the leading edge, and two zippers x for opening extending from both sides of the knob portion 11a are formed. Two zipper y for opening similarly to the zipper x of the front panel 11 are formed in parallel to the inward curved folding line e on both sides to reach the boundary with the back panel 13. The zippers x and y of the front panel 11 and the top panel 12 are formed by continuous "<"-shaped notches as shown in the figure. The part surrounded by these zippers forms an opening part.

  The knob 11a of the front panel 11 has a convex portion 11b partitioned by cutting, and can be bent along folding lines j on both sides of the convex portion 11b. In correspondence with the convex portion 11b of the knob 11a, an insertion slit 15b having both ends curved and a notch in the middle is formed in the center of the glue margin panel 15.

  This blank B is sack pasted to the store where it is assembled with its contents and toppings. The procedure is as follows.

  First, at the folding lines a and c, the blank B is folded so as to be folded, and the back surface of the outer portion of the zipper x in the front panel 11 and the front surface of the adhesive margin panel 15 are bonded together as shown in FIG. Then, a plurality of blanks B sack pasted in this way are sent together to the store.

  At the shop front, the blank B in the state of FIG. 3 with the sack is raised in a square tube shape, and then either one of the square tube openings is closed. In this case, the side inner panel 17 is folded inward along the fold line f while folding the web corners on both sides thereof, and then folded along the fold line e so as to overlap the side outer panel 16, and the insertion piece 16a is inserted into the slit 17b and fixed. . Then, put the contents and toppings through the other opening, and close this one in the same way that you closed it earlier.

  Thereby, the pillow type carton C shown in FIG. 1 is formed. Then, the top panel 12 and the bottom panel 14 are curved in a shape in which the side inner panel 17 and the side outer panel 16 are stretched, and a carton having a curved top and bottom is obtained.

  If the pillow type carton C is rotated several times by hand so that the contents and the toppings of the pillow are rotated, the toppings are uniformly attached to the contents. In this work, the dust flap is used as the web corner, so that the contents and the topping do not leak outside. In this state, it is displayed at the storefront and provided to the customer. The legs 16a on both ends of the side outer panel 16 form legs around the four places, and these serve as grounding portions. It can be placed on a flat surface such as a sales stand or table in a stable state that does not swing when displayed or when a customer eats.

  The pillow type carton C shown in FIG. 1 uses the display piece 16d provided on the side outer panel 16 when the contents and toppings are arranged at the storefront, and raises this portion as necessary. Product items can be seen at a glance.

  In order to open the pillow type carton C, the zipper x of the front panel 11 is broken while being lifted while picking the tab 11a of the front panel 11 with the fingertips and bent along the fold line j, and pulled to the rear as it is. When the zipper y of 12 is also broken, the opening portion is lifted with the boundary with the back panel 13 as a hinge, and a large opening is formed from the front panel 11 to the top panel 12. When the opened pillow carton C is closed, the unsealed portion is returned to the original position, and the convex portion 11b of the knob portion 11a is inserted into the slit 15b of the adhesive margin panel 15 and locked.

  As mentioned above, although the form for implementing this invention was demonstrated in detail, the pillow-type carton by this invention is not limited to said form at all, In the range which does not deviate from the meaning of this invention, various change It is natural that this is possible.

  The pillow type carton of the present invention is not only used for putting contents (solid, granular) and topping (powdered, granular) at a fast food store, but also when directly packing other foods. Can also be suitably used.
