The body part is formed by gluing the back side of the side panel, and two opposing side panels are left and right side panels, and dust flaps are connected to the upper and lower sides respectively, and the other two Two side panels become front and back side panels, and lid panels are connected to the upper and lower sides of each side panel. Each lid panel is cut into four rounded corners, and four straight lines are connected to each other alternately. It is composed of a part with four curved portion corresponds to the width of the linear portion and both sides of the combined length of the curved portion front and rear side panels to be connected to the front and rear side panels, parallel to the sides of the front and rear side panels The length of the straight line is the left and right sides Corresponds to the width of the panel, the top and bottom of each front and rear side panels is provided with ledge on the left and right lid panel is folded inwardly with respect to the longitudinal side panel, it is fitted in and along the inside of the ledge Contact turned state is, front and rear side panels is characterized that it is quadric convex outward to fit the shape of the lid panel.

  The quadric surface carton of the present invention is designed to sack a single blank, unfold the sack pasted state, put the product inside, and then fold the lid panel in order to assemble it. Therefore, it can be delivered in a sack-attached state, compared to conventional quadratic curved carton, manual boxing work is easy and workability is good, and furthermore, there is no part that curves inward, It is efficient in terms of physical distribution because of the large volume of products.

It is a perspective view which shows an example of the quadratic curved surface carton concerning this invention. It is an expanded view of the blank which assembles the quadric surface carton of FIG. It is a top view shown in the state which stuck the blank of FIG.

  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 quadric curved carton C according to the present invention, and this quadric curved carton C is formed by assembling a blank B whose development is shown in FIG.

Figure 2 blank B has been prepared by punching a paperboard used for ordinary paper containers, as shown, four side panels 1-4 and margin piece 5 parallel folding ruled together with a rectangular shape Are arranged in the horizontal direction in this order.

Breadth narrower side panels 1 and 3 are made of the left and right side panels during assembly, one of the left and right side panels 1 of the dust flaps 6 and 7 on the upper side and lower side are continuously provided via Orikei each other Dust flaps 8 and 9 are connected to the upper and lower sides of the left and right side panels 3 via folding lines, respectively. Further, the side panels 2 and 4 having a larger width become front and rear side panels when assembled, and lid panels 10 and 11 are connected to the upper and lower sides of one front and rear side panel 2 via folding lines. The lid panels 12 and 13 are connected to the upper and lower sides of the other front and rear side panel 4 via creases.

  Each lid panel 10-13 is the shape which rounded the four corners of the rectangle, and is comprised by four linear parts and four curved parts which the circumference | surroundings connect alternately. The length of the straight portion connected to the front and rear side panels 2 and 4 and the curved portions on both sides thereof corresponds to the lateral width of the front and rear side panels 2 and 4, The lengths of the parallel straight portions correspond to the lateral widths of the left and right side panels 1 and 3.

  The lid panel 10 connected to the upper part of the front and rear side panels 2 has an insertion piece 10a connected to the straight portion at the tip side thereof via a crease, and the other piece corresponds to the insertion piece 10a. The front and rear side panels 4 are formed with slits α at the upper portion thereof, which are semicircular shapes for locking the insertion piece 10a and have small semicircular portions that are inverted at both ends. Further, the lid panel 12 connected to the upper part of the front and rear side panels 4 is provided with a protruding piece 12a connected to the straight portion on the tip end side via a crease. A small arc-shaped notch β is formed at the base of the projecting piece 12a so that the convex portion protrudes when bent.

  In addition, protrusions 2a projecting into a space between the upper and left sides of the front and rear side panels 2 and the curved portion of the lid panel 10 provided continuously are provided, and between the curved portions of the lid panel 11 provided also on the lower side and right and left sides. A protrusion 2b protruding into the space is provided. Similarly, protrusions 4a are provided on the upper left and right sides of the front and rear side panels 4 so as to protrude into the space between the curved portions of the lid panel 12 provided continuously, and between the curved portions of the lid panel 13 provided also on the left and right sides of the lower side. Protrusions 4b projecting into the space are provided, and these protrusions 4a and 4b are formed leaving a gap between the cover panels 12 and 13. Here, as shown in the figure, the protrusions 2a, 2b, 4a, 4b have a trapezoidal shape with a low height.

  The blank B shown in FIG. 3 is assembled to form the quadratic curved carton C shown in FIG. 1. As the procedure, first, the adhesive margin piece 5 is bonded to the back of the front end of the left and right side panels 1 on the opposite side and folded. Thus, the sack pasting state as shown in FIG. 3 is obtained. Then, the sack pasted state is sent to the retail store, where it is manually assembled and boxed.

  The boxing operation for putting the product is performed by a procedure in which a blank with a sack is raised in a box, the upper part or the lower part is assembled and closed, and the upper or lower part remaining after the product is put in is assembled and closed. Thereby, the quadric surface carton C shown in FIG. 1 is formed.

  For example, when closing from the bottom, following the raising of the box, the dust flaps 7 and 9 of the left and right side panels 1 and 3 are tilted inward, and then the lid panel 13 of the front and rear side panels 4 is moved to the front and rear side panels. 2 so that the lid panel 11 of the front and rear side panel 2 is also placed along the inside of the protrusions 4b and 4b of the front and rear side panel 4 in the same manner.
