[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIGS. 1 to 7 show an example of an embodiment of the present invention, and the basic configuration is the same as that described in Patent Document 1 described above.
[0009]
FIG. 1 is an exploded view of a blank constituting the body of the carton of the present embodiment. As a material used for the blank, for example, it is preferable to use a sheet mainly composed of paper and having a basis weight of 400 g / cm ² or more.
[0010]
In this embodiment, four rectangular panels 1 to 4 forming a carton body C are connected in one direction to the center of the blank sheet. In the drawing, reference numeral 1 denotes a rear panel, 3 denotes a front panel, and 2 and 4 denote left and right side panels, which are alternately connected to each other via a fold line. Reference numeral 5 denotes a body sticking flap (adhesive margin piece) connected to one end edge of the side plate 1.
At the lower ends of the back panel 1 and the front panel 3, outer flaps 6 and 8 for sealing the bottom surface are respectively provided, and at the lower ends of the left and right side panels 2 and 4, inner flaps 7 and 9 for sealing the bottom surface are folded. Connected through.
Folded pieces 11 to 14 are connected to the upper ends of the four panels 1 to 4, respectively.
[0011]
When the four panels are attached to the body, the folded pieces 11 to 14 are folded inside the four panels 1 to 4. This serves to reinforce the upper part of the carton, prevent powder leakage, and stabilize the moisture-proof seal paper.
The folding line provided between each panel and the folded piece may be a normal ruled line, but a half-cut line or a perforation is cut on the ruled line by cutting to about half the thickness of the blank plate and then bent. It is preferable to make the folding line easier (this is called a lead rule).
[0012]
In addition, a cut-and-raised connecting piece 15 is defined on a surface of the back panel 1 where the folded piece is joined (a portion hatched in FIG. 1). The connecting piece 15 is provided with folding lines X1 and X2 used as hinges of the connecting piece at a horizontal position below the connecting piece 15 and connects a braking projection Y projecting below the folding line between the folding lines X1 and X2. It is formed integrally with the piece 15. The upper portion of the connecting piece 15 is formed so as to be separated from the back panel 1 by a cutting line Z connecting one end of the folding line. Incidentally, the cutting line Z shown in the figure is formed in a U-shape opened downward.
[0013]
At the time of forming the body panel of the carton, the folded pieces 11, 12, 13, and 14 connected to the upper end of each panel are folded inside the panels 1 to 4 and adhered. Next, the body sticking flap 5 is attached to the side panel 4. After forming the torso, the inner flaps 7 and 9 for sealing the bottom are bent inward so as to be substantially perpendicular to the side plates 2 and 4, and the outer flaps 6 and 8 for sealing the bottom are folded out of the inner flaps 7 and 9. Overlap and glue. Then, after sealing the bottom of the body, the contents are placed in the body of the carton, and the opening of the body of the carton is top-sealed with a sealing material such as glassine paper so that the contents are not scattered.
[0014]
FIG. 3 is an exploded view of the cover lid blank, in which the front panel 22 of the lid, the rear panel 23 of the lid, and the right and left panels 24, 25 of the lid are connected to each other on four sides of the rectangular lid plate 21 via fold lines. The end portions of the lid panel are linked by corner pieces 26 to 29 and are configured to fit on the upper surface of the body of the carton. FIG. 4 is an explanatory view of assembling the cover. The cover has a cylindrical shape by attaching a connecting piece 15 for the cover to the inside of the rear panel of the cover after the top seal is made on the opening surface of the body. The packaging work is completed by being integrally attached to the body C. (See Fig. 5)
[0015]
Next, the operation of the cover according to the embodiment will be described. When the cover is opened and closed at the time of use, the cover is rotated using the folding lines X1 and X2 provided on the connecting piece 15 connecting the cover and the body of the carton as hinges. . That is, when opening and closing the cover, the braking projection Y integrally formed at the lower portion of the connecting piece is brought into contact with the folded piece 11 adhered to the inside of the back panel as shown in FIG. Thus, the flipping piece can be flipped inward to perform an opening / closing operation with a sense of moderation (click feeling). (See FIGS. 6 and 7B)
[0016]
When the cover is rotated by 90 degrees or more, as shown in FIG. 7B, the braking projection Y formed at the lower portion of the connecting piece 15 rotates upward beyond a horizontal level, and then the rear panel is rotated. Since it is locked by the folded piece 11 adhered to the inside of 1, the cover does not remain in a half-open state and does not wobble when taking out the contents from the carton body. In addition, since the cover is stable at a fully opened position of 90 degrees or more, it is not necessary to press the cover with a hand, so that the work of dispensing the contents is facilitated.
Further, when resealing, the cover and the body of the carton are connected by a hinge, so that the carton and the lid do not separate and dissipate, and are easy to reseal. Note that the hinge width is preferably set to 2/3 or more of the box width (width of the body portion), and in this case, the lid can be stably opened and closed. If the width of the protrusion of the braking projection Y toward the folded piece 11 is 3 mm or less, a smooth feeling of movement is obtained, which is preferable. However, if it exceeds this, the cover may be difficult to fully open.
[0017]
The position of the braking projection Y of the present invention is not limited to the above embodiment. That is, in the above-described embodiment, one is provided between the folding lines X1 and X2, but it is also possible to form two or more on the connecting piece as shown in FIG. An example is shown in FIG.
[0018]
【The invention's effect】
As described above, according to the present invention, as described above, the lid is easy to open at the time of opening, that the lid can be easily resealed, and the lid is left in a half-open state when the powder detergent is taken out using a spoon or the like, An excellent effect is obtained that the entire surface can be opened without wobbling and the lock can be locked at the fully opened position so that the lid does not return.
