Description

Packing box {PACKAGING BOX}

The present specification relates to a packaging box used for packaging and delivery of goods.

In general, a packaging box is used when shipping or storing goods, and is usually manufactured by folding a paper fabric into a cube such as a rectangular parallelepiped. In the packaging box folded into a cube, the product to be packaged is stored in a storage space therein and then sealed with plastic tape or paper tape to complete the packaging.

In recent years, consumption through online shopping such as an open market has been activated, and the cases where purchased goods are delivered through courier companies have increased exponentially. Accordingly, the use of packaging boxes for packaging and delivery of purchased goods has also increased.

However, since the seller uses plastic tape to put the goods to be delivered into the packaging box and seal it tightly, there is a difficulty in separating the plastic tape from the packaging box in order to recycle the packaging box.

In addition, after use, there is a problem that environmental pollution is increased due to the discarded plastic tape.

On the other hand, paper tapes are sometimes used to prevent environmental pollution and facilitate the recycling of packaging boxes, but paper tapes are not widely used because the cost is dozens of times higher than when using plastic tapes.

Hereinafter, a process of sealing a packaging box according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

3 is a diagram sequentially showing a process of sealing a packaging box according to an embodiment of the present invention.

Fig. 3(a) shows a state in which both the top and side support surfaces of the packaging box are open.

Fig. 3(b) shows a state in which the side support surfaces of the packaging box are all closed.

3(c) shows a state in which a part of the upper surface of the packaging box is closed.

Fig. 3(d) shows a state in which all of the upper surfaces of the packaging box are closed and completely sealed.

Briefly describing the process of sealing the packaging box according to an embodiment of the present invention with reference to the drawings, after the goods are stored in the storage space 105, the side support surfaces 220 and 240 are folded to form the storage space 105. ), and then folded in order of the upper surface 210 and the upper surface 230 to cover the storage space 105.

First, the user accommodates the article in the storage space 105 and then folds the side support surfaces 220 and 240 with respect to the folding portions 125 and 145 to cover the storage space 105. The side support surfaces 220 and 240 may be completely folded so that one side thereof may be interviewed on the inner surfaces of the left and right side surfaces 120 and 140.

Subsequently, the user folds the upper surface 210 with respect to the folding part 115, and then fits the side opening/closing coupling protrusions 251, 252 into the side opening/closing grooves 261, 262 to fit the upper surface 210 Fix the surface 210.

Thereafter, the user folds the upper surface 230 with respect to the folding part 135, and then fits the side opening/closing coupling protrusions 253, 254 into the side opening/closing grooves 263, 264, The upper surface 230 is fixed.

Finally, the user may fit the front opening/closing coupling protrusion 255 of the upper surface 230 into the front opening/closing coupling groove 265 to more firmly fix the upper surface 230.

1 and 2, the side opening/closing coupling protrusions 251 and 252 are formed on the left and right ends 212 and 214 of the upper surface 210, and the left and right ends 212 and 214 are two parts. When divided into, it may be formed in a portion far from the folded portion 115 between the upper surface 210 and the front side (110).

Accordingly, the side opening/closing coupling protrusions 251, 252 are formed in the side opening/closing coupling grooves 261, 262 formed at a distance from the folding part 115 among the plurality of side opening/closing coupling grooves 261, 262, 263, 264. Can be inserted and fixed.

In addition, the side opening/closing coupling protrusions 253 and 254 are formed on the left and right ends 232 and 234 of the upper surface 230, and when the left and right ends 232 and 234 are divided into two parts, the upper surface It may be formed in a portion far from the folded portion 135 between the (230) and the rear side (130).

Accordingly, the side opening/closing coupling protrusions (253, 254) are in the side opening/closing coupling grooves (263, 264) formed at a distance from the folding part 135 among the plurality of side opening/closing coupling grooves (261, 262, 263, 264). Can be inserted and fixed.

As described above, in a state in which the upper surfaces 210 and 230 are folded and overlapped with each other, the side opening and closing protrusions 251, 252, 253, and 254 are provided with the side opening and closing grooves 261, 262, 263, 264), since the second upper surface 230 is completely superimposed on the first upper surface 210, the upper surface of the packaging box is tightly sealed only by the coupling force between the side opening and closing coupling protrusion and the side opening and closing groove. can do.

In addition, when the front opening/closing coupling protrusion 255 is inserted into the front opening/closing coupling groove 265, the upper surface can be more tightly sealed, so that the upper surfaces 210 and 230 are made of plastic tape or paper. The packaging box can be tightly sealed without sticking with tape or the like.

Hereinafter, the opening/closing coupling protrusion and the opening/closing coupling groove will be described in detail with reference to FIG. 4.

4 is a view showing a front opening and closing engaging projection and a front opening and closing engaging groove portion, and a side opening and closing engaging projection and a side opening and closing engaging groove portion.

4(a) is a view showing a front opening/closing engagement protrusion and a front opening/closing engagement groove.

4(b) is a view showing a side opening/closing engagement protrusion and a side opening/closing engagement groove.

Referring to FIG. 4, the shape of the front opening/closing coupling protrusion 255 may be a semicircular shape, and the shape of the side opening/closing coupling projection 251, 252, 253, 254 may be a quadrant shape.

In addition, the width (W1) of the front opening/closing engagement protrusion 255 is larger than the width (W2) of the front opening/closing engagement groove 265, and the width (W4) of the side opening/closing engagement protrusions 251, 252, 253, 254 ) May be larger than the width W5 of the side opening and closing grooves 261, 262, 263, and 264. The width (W3) of the connection portion (255-1) of the front opening and closing protrusion 255 and the front end 236 of the upper surface 230 is equal to the width (W2) of the front opening and closing groove 265 or small. In addition, the connection portions (251-1, 252-1, 253-1) of the side opening and closing protrusions (251, 252, 253, 254) and both side ends (212, 214, 232, 234) of the upper surface (230) The width W6 of the 254-1) is equal to or smaller than the width W5 of the side opening/closing grooves 261, 262, 263, and 264.

Therefore, the opening and closing protrusions (251, 252, 253, 254, 255) of the packaging box made of a paper material such as corrugated cardboard can be easily inserted into the opening and closing grooves (261, 262, 263, 264, 265), After being inserted, both ends of the opening/closing coupling protrusions 251, 252, 253, 254, and 255 are caught in the opening/closing coupling grooves 261, 262, 263, 264, 265 and can be tightly coupled.

According to another embodiment of the present invention, the packaging box may further include side wings (not shown) folded and extended from the left and right ends of the front and rear sides 110 and 130 or the left and right ends of the left and right sides 120 and 140. I can.

When the front and rear left and right sides 110, 120, 130, and 140 are erected, the side wings may be bonded to adjacent side surfaces or may be fixed with a stapler or the like. Accordingly, the packaging box can maintain its shape even when the upper surfaces 210 and 230 and the side support surfaces 220 and 240 are open.
