Description

Packing paper box {PACKAGING PAPER BOX}

The present invention relates to a paper box, and more particularly to a paper box for packaging that can package food and other objects such as dried fruits and chocolates such as sweets.

In general, a packing box is a package of dried foods such as confectionery, chocolate, food, cosmetics, soap, shampoo, writing instruments, clothing, and other items, to facilitate the movement of the goods and to make the outside of the packaging box beautiful. Designed to inspire consumption and to protect the contents of the packaging box.

Conventional packaging paper box also has a function to take out the contents without opening the packaging box by forming an opening on the cover (top) portion of the packaging box.

However, in the conventional packaging box, since the unsealed state of the unsealed portion is unstable after the unsealed portion is opened, the unsealed portion often passes down or backwards, so users have to take a lot of inconvenience.

In addition, when the packaging paper box is processed (when discarded or stored as a waste), a large amount of space is wasted due to the internal volume of the packaging paper box.

In addition, even when the packaging paper box is folded and processed so that there is no internal space, there is a problem that the packaging paper box must be torn and folded with a lot of force.

The present invention has been proposed to solve the problems of the prior art, and provides a paper box for packaging including an opening having a protrusion to facilitate opening and closing of the opening of the paper box and an insert into which the protrusion is inserted. There is a purpose.

In addition, another object of the present invention is to provide a packaging paper box including a bent portion in the opening to stably maintain the opening state of the opening of the paper box.

In addition, another object of the present invention is to provide a packaging paper box including a pressing portion and a perforated line of a certain shape to easily tear and fold the paper box when processing the paper box.

Packaging paper box according to the present invention for solving the above technical problem is a rectangular parallelepiped packaging paper box including the front, rear 40, top 10 and the bottom 50, as described in claim 4, The front surface is formed of an inner front surface (30) and an outer front surface (20) which are folded and attached onto the inner front surface (30); An opening part (11) opened from the outer front surface (20) onto the upper surface (10); Forming a projection (12) partitioned by an incision line (5) at the tip of the opening (11) formed on the outer front surface (20); The inner surface 30 corresponding to the protrusion 12 is formed with an insertion portion 14 into which the protrusion 12 is inserted, and the opening portion 11 is formed from the protrusion 12 to the upper surface 10. Gradually forming a cutting line (17a) to be cut off; The perforation line 17a which meets the upper surface 10 is formed in parallel to a point forming a predetermined distance W from the rear surface 40; Both ends of the perforated line 17a having a predetermined interval with the rear surface are connected to the folding grooves 16, and the folded portion 15 to maintain the opening state of the opening portion 11 at the rear end of the opening portion 11. Further formed, the bent portion 15 is characterized in that divided by the incision line (5a, 5b) formed over the upper surface 10 and the rear surface (40).

In this case, two protrusions 12 are formed at left and right portions of the protrusion 12.

In addition, while forming a cutting line (17a) to be cut while gradually extending from the protrusion 12 to the upper surface 10, the width of the left and right cutting line (17a) that meets the upper surface 10 is the upper surface (10) It is formed to be narrower than the width of.

At this time, the perforation line 17a may be variously shaped such as a straight line, a wave shape, a triangular shape, and the junction part 19 is formed between the perforation lines 17a. The opening 11 is opened while the junction 19 between the cut lines 17a is torn off.

In addition, the left and right cut lines 17a that meet the upper surface 10 are formed in the rear surface 40 in parallel with the left and right folding lines 3 of the upper surface 10, and the left and right ends of the cut lines 17a are formed. Is positioned to maintain a predetermined distance (W) with the rear surface 40, both ends of the left and right cut line (17a) is connected to the folding groove 16, forming the other end of the opening portion (11) do.

In this case, the cutting line 17 formed on the upper surface 10 and the outer front surface 20 may be formed by cutting all except the junction portion 19 for ease of opening of the opening portion 11. .

The outer front surface 20 is folded and attached to the outside of the inner front surface 30 to form the front of the packaging paper box together.

At this time, the opening part 11 and portions of the inner front surface 30 corresponding to the opening part 11 are not bonded to each other.

When the outer front surface 20 is folded onto the inner front surface 30 and attached to the inner front surface 30, an incision line is formed at a portion corresponding to the protrusion 12 that forms one end of the opening part 11. An insertion portion 14 partitioned by (5) is formed.

Therefore, after opening the opening part 11 of the packaging paper box, the protrusion 12 may be inserted into the insertion part 14 to maintain a closed state.
