Description

[Detailed description of the invention] Technical field This invention includes a lid part that can open and close the opening,
The present invention relates to a packaging box whose opening is closed with a lid and sealed with adhesive tape.

PRIOR ART Traditionally, almost all packaging boxes containing small items such as medicines are sealed or sealed.
An adhesive tape made of cellophane is pasted across the lid and the box body. This seal is indispensable for both producers and consumers as it guarantees the value and reliability of the product. However, cutting and opening the adhesive tape used for sealing is inconvenient and time-consuming for consumers.

A cutting tool such as a knife, cutter, or scissors must be used to open the package. Furthermore, if the package is opened using a fingernail or the like, the periphery of the opening of the packaging box may get stuck between the finger and the nail, causing bleeding. Furthermore, if an attempt is made to forcefully open the package without using a cutting tool, the packaging box will be damaged and its appearance will be significantly impaired.

Purpose The present invention was developed in view of the above circumstances, and its purpose is to provide a cutting and opening device that does not require a cutting tool when cutting and opening adhesive tape attached to seal a packaging box. It's about doing.

Embodiment Hereinafter, one embodiment of this invention will be described in the first to
This will be explained according to FIG. Packaging box C made of paper
The opening of the packaging box is covered with a lid part 1 which is openable and closable on the rear edge of the opening, and the packaging box front wall part 2
A sealing tape P made of cellophane is attached to an arbitrary location T of the engagement portion between the upper edge 3 and the open end 11 of the lid portion 1.

A pair of linear cut lines 4 extending from the upper edge 3 of the packaging box C toward the bottom to form a "S" shape are attached to the attachment point T of the adhesive tape to be attached. 5 will be provided.

A slight gap 7 is provided at the confluence of the "S"-shaped score lines 4 and 5 so that the isosceles triangle-shaped paper piece 6 formed by the "S"-shaped score lines 4 and 5 is not separated. Further, the length of the base 8 of this isosceles triangle-shaped paper piece 6, that is, the distance between the opening side edges of both the score lines 4 and 5, is slightly larger than the width of the adhesive tape P to be pasted. The cutting angle of each cutting line 4, 5 is set as follows.

Note that the adhesive tape P made of cellophane has a large tensile stress in the length direction and cannot be easily cut. However, since the shear stress is relatively small, both the front and back sides of the adhesive tape P have It can be easily cut by applying force towards it.

Now, in order to cut the sealing adhesive tape affixed to the packaging box according to the present invention, it is necessary to cut the outer box C and the open end 11 of the lid part 1 on both left and right sides of the adhesive tape P.
Place your thumb and index finger between C,
If force is applied in the direction that 11 separates, the adhesive tape P will align with the score lines 4 and 5,
It resists the shearing stress and is instantly cut, completing the opening. FIG. 4 shows the state after cutting and opening according to the present invention. The isosceles triangular piece of paper 6 is completely separated from the outer box C and hangs from the open end 11 of the lid 1, making it easier to open and close the lid 1 thereafter.

Traditionally, there are hundreds of types of medical drugs sold in packaging boxes, and injectable drugs such as antibiotics require the National Preliminary Research Institute's National Certification Certification. Although these adhesive tapes are valuable in their necessity, for consumers, opening the packages of these hundreds of medical products is one of the challenges. It can be counted as. Especially in medical institutions, there is no other product that can exhibit such excellent properties that it can be opened easily without using cutting tools. Especially for medical products, since it takes many days from production to shipping and from wholesaler to consumer, the adhesive tape attached is completely adhered to the surface of the outer box C, and it is difficult to open the package with your fingertips. becomes simpler.

Effects As detailed above, this invention provides a "S"-shaped cut line in front of the adhesive tape that is attached to seal the outer box, so that it can be used for sealing or sealing. This has the excellent effect of allowing the adhesive tape pasted to be opened easily and instantaneously with a fingertip without using a cutting tool.

Claims (1)

[Claims for Utility Model Registration] A lid 1 that can open and close an opening;
In a packaging box C that is sealed with an adhesive tape P with the opening closed, the side wall 2 of the packaging box C has a "S" shape extending from the upper edge of the opening toward the bottom. A pair of score lines 4 and 5 are provided, and in order to prevent separation of the triangular piece 6 formed by both score lines 4 and 5 and the upper edge of the opening, a pair of score lines 4 and 5 are provided that extend to the opening. A gap 7 is provided between the side edges, and the gap between the opening side edges of both score lines 4 and 5 is set to be larger than the width of the adhesive tape P. Leave the ends and cut both sides 4,
A packaging box characterized in that an adhesive tape P is pasted on the top of the packaging box.
