Description

Packaging box that blocks the inflow of foreign substances}

The present invention relates to a packaging box that blocks the inflow of foreign substances.

In general, a packaging box used to pack an article can be made of paper, wood, plastic, or metal, but it is most common to make a paper material such as corrugated cardboard in order to reduce the weight of double cargo.

The packaging box made of paper material may be manufactured in various shapes such as a rectangle or a circle by using corrugated cardboard, and a handle into which a user's hand can be inserted may be disposed.

In this way, the handle part for carrying the user's goods is formed by removing a part of the packaging box. There is a complex problem in that foreign substances and the like introduced through such a handle can contaminate the goods inside the packaging box, and the size of the handle is reduced due to a problem in that rigidity is weakened, reducing user convenience.

The problem to be solved by the present invention is to provide a packaging box that blocks the inflow of foreign substances.

The tasks of the present invention are not limited to the tasks mentioned above, and other technical tasks not mentioned will be clearly understood by those skilled in the art from the description below.

A packaging box for blocking the inflow of foreign substances according to an embodiment for solving the above problem includes a third side, a first side, a fourth side and a second side sequentially disposed in a first direction, and the third side It includes a first handle hole disposed on a side surface and a second handle hole disposed on the fourth side surface, and a first handle hole cover portion connected to the third side surface and a second handle hole cover portion connected to the fourth side surface portion. Including, a first folding line disposed at a portion where the first handle hole cover portion and the third side surface contact each other, and a second folding line disposed at a portion where the second handle hole cover portion and the fourth side surface come into contact with each other And, when assembling the packing box, the first handle hole cover part covers the first handle hole along the first fold line, and the second handle hole cover part covers the second handle hole along the second fold line. and a first rigidity reinforcing part contacting the first handle hole cover in a second direction crossing the first direction when assembling the packing box, and the second handle in the second direction when assembling the packing box. It further includes a second rigidity reinforcement part contacting the hole cover part, wherein the first rigidity reinforcement part is adhesively fixed to the third side surface and the second rigidity reinforcement part is adhesively fixed to the fourth side surface when the packing box is assembled.

A first upper cover portion connected to the first side surface and a second upper cover portion connected to the second side surface may be further included.

Lengths of the first handle hole cover portion and the second handle hole cover portion in the second direction may be longer than lengths of the first upper cover portion and the second upper cover portion in the second direction.

The first upper cover may include a first part, a second part connected to one side of the first part, and a third part connected to the other side of the first part.

The second part covers a part of the third side surface when assembling the packing box, the third part covers a part of the fourth side surface when assembling the packing box, and the first handle hole and the second handle hole It may further include cover patches disposed on each.

According to the packing box blocking the inflow of foreign substances according to an embodiment, the handle hole of the packing box can be easily covered, effectively blocking the inflow of foreign substances from the outside and increasing the rigidity of the packing box.

Furthermore, since the handle hole can be easily covered in the box manufacturing process, commercial efficiency can be improved. In addition, it is possible to improve the inefficiency or high cost problem of applying a small handle that reduces user convenience due to the box rigidity problem or increasing the thickness of the box base paper.

The first rigidity reinforcement part RC1 and the second rigidity reinforcement part RC2 may be formed in a rectangular shape, but are not limited thereto, and may be formed in various shapes such as a triangular shape and a circular shape, and the first rigidity reinforcement part RC1 and Each of the second rigidity reinforcing parts RC2 may be formed of a plurality of rigidity reinforcing part pieces.

In some embodiments, the ratio of the lengths of the first handle hole cover part (HCP1) and the first rigidity reinforcement part (RC1) may be 7:3, and the second handle hole cover part (HCP2) and the second rigidity reinforcement part (RC2) The ratio of the lengths of may be 7:3. However, it is not limited thereto.

Referring to FIGS. 10 and 11 , the packaging box (PB) for blocking the inflow of foreign substances may further include a cover patch (CVP). The cover patch CVP may be disposed in the first handle hole HH1 and the second handle hole HH2.

For example, the cover patch CVP may be disposed on the third side surface SP3 and the fourth side surface SP4, and may be disposed surrounding the first handle hole HH1 and the second handle hole HH2. In addition, the cover patch (CVP) may be disposed on inner surfaces of the third side surface (SP3) and the fourth side surface (SP4) in which objects are accommodated when assembling the packaging box (PB) blocking the inflow of foreign substances, and the adhesive material (AM) ), it may be adhesively fixed to the inner surfaces of the third side surface SP3 and the fourth side surface SP4. The cover patch (CVP) may be made of vinyl, but is not limited thereto, and may be made of various materials such as rubber, paper, and fiber. In addition, the cover patch CVP may be adhesively fixed to the inner surfaces of the third and fourth side surfaces SP3 and SP4 in a state in which a predetermined space is formed in order to secure a space in which a user's hand is accommodated from the outside.
