Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device in which a pack box can be easily opened using a redacting piece (3). This invention will be explained with reference to the drawings. In the figure (1) is a pack box. body of (2)
is an adhesively bonded state, (3) is a re-datsu piece, (4) (4') (
4") (4"') (4"") is the score line, (5) (5'
) is the inner adhesive part, (6) is the folding line (7) is the knob part, (
8) is the cutout, (9) (9') is the upper part of the outer adhesive, (10
) is an unsealed portion, (11) is an open state, (12) is an unsealed state, and (13) is an arrow indicating the direction in which a score line is to be made.

Since the pack box opening device according to the present invention is constructed as described above, as shown in FIG. 4)
Add (4') (4'') (4''') (4'''') to the folded line (
6), bend the knob part (7) outward as shown in Figure 5, and after gluing the inner adhesive parts (5) (5'), glue the outer adhesive upper parts (9) (9') to form an adhesive bonded state. Make (2) and seal it. When using, open the open position (11) and press the knob (
By peeling off the adhesive using the tool 7), the re-datsu piece (3) can be re-dutatsu to create a cut-out opening (8) and an unsealed state (12). Fourth
As shown in the figure, the main body (1) is expanded and cut along the score lines (4'') (4'').
') (4'') is made by making an incision at an arbitrary depth from the inner surface of the expanded body (1) in the direction indicated by the arrow (13) as shown in FIGS. 5 and 6.

Conventional pack boxes could not be opened easily even if they were made in the open state (11) because the adhesive was strong as shown in the open state (12), but by providing a re-datsu piece (3) with a notch, the package can be opened easily. It is very convenient, hygienic, inexpensive to manufacture, and has practical effects.

[Brief explanation of drawings]

Fig. 1 is an oblique view of the pack box, Fig. 2 is an oblique view showing the notch state of the opening part (10), and Fig. 3 is a side view showing the knob part (7) and adhesive parts (5) (5'). , Figure 4 shows the main body (1)
Fig. 5 is a side view showing the state in which the knob part (7) is bent downward and glued, and Fig. 6 is a plan view showing the cut lines and folding lines (6) when expanded. A plan view showing the state in which each incision is made from the inside, Figure 7 is the open state (11)
FIG. 8 is a perspective view showing a state in which the redacting piece (3) has been redacted and opened. Patent applicant, Hikaru Nakai ■

Claims (1)

[Claims] A cut line (4
) (4') (4") (4"') (4"") and folding line (6
) and adhesive parts (5) (5') are provided, and a knob part (7) is provided above, and the knob part (7) is bent downward to form an inner adhesive part (5).
) (5') and the outer adhesive upper parts (9) and (9') on the top of the knob part (7) to create an adhesive bonded state (2) and seal it. When in use, the opening state (11) is created and the re-datsu piece is re-tightened from the main body (1) using the knob (7) to create the unsealed state (12) and the seal is opened by creating a cut-out opening (8). The cut line (4″′) (4″″) is the main body (1
) before assembling, unfold it as shown in Figure 4 and mark the notch line (4"
’) (4″″), cut the cutting line (4) (4
') (4'') is the inner surface of the main body (1) which is unfolded as shown in Figs. An opening device for pack boxes that has a notch so that it can be opened.
