Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority of Korean Patent Application No. 10-2019-0084782 filed on Jul. 12, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a curing device, and more particularly, to a curing device for curing a curing target using light energy and heat energy.

Description of the Related Art

A box for packing an article for a parcel service is generally made in a rectangular box shape and the article is put together with a buffer or the like if necessary.

There is a folded and finished cardboard box made of corrugated paper or cardboard synthetic resin, which is widely used as a box for packaging. A type in which both a bottom and a top are taped and finished with a box tape is the simplest and does not require a separate special cutting process, and as a result, the type is widely used for packaging mass-produced products.

However, such a box has a disadvantage in that a separate bonding process and/or taping operation should be performed on upper and lower surfaces twice. In order to overcome such a disadvantage, various prefabricated boxes are proposed in the related art.

In the one-sided prefabricated packaging box in the related art, a separate bonding process or taping operation is required to complete the upper surface, and thus, there is a disadvantage in that associated costs such as cost and manpower are increased.

In recent years, the number of examples of businesses operating through Internet shopping malls has increased and the number of small and medium-sized businesses and individual businesses dealing with small parcels has increased.

Therefore, the need for a structure of a packaging box that can reduce the cost required for packaging while at the same time satisfying a desired rigid packaging strength without a separate taping operation is increasing.

In addition, even in large-scale production lines, there is a need for improvement measures to finish packaging by simply bending without the need for separate taping and stapling processes.

The above-described technical configuration is a background technique for assisting the understanding of the present invention, and does not mean a conventional technology widely known in the art to which the present invention belongs.

SUMMARY OF THE INVENTION

Accordingly, the present invention has been made in an effort to provide an econ friendly tapeless packaging box which may be combined even without a taping operation and secure a desired packaging strength.

An exemplary embodiment of the present invention provides an eco friendly tapeless packaging box including: a box body in which one side portion is opened; a cover part covering an opened area of the box body; and a block portion provided in the box body and supporting the cover part, in which the cover part is divided into two areas and fitted and coupled to each other and includes a cover coupling portion which is fitted and coupled to a coupling hole provided at a wall portion of the box body.

The cover part may include a first cover part provided in the box body and having a first cover coupling hole, a second cover part provided in the box body of an area facing the first cover part and having an insertion coupling plate fitted and coupled the first cover coupling hole, and the cover coupling portion provided in the second cover part and fitted and coupled to the coupling hole.

The cover coupling portion may include a base cover coupling plate extending on an edge of the second cover portion and bent and contacting a side wall of the box body, a fixation plate extending on the base cover coupling plate and inserted into the coupling hole, and a separation preventing plate provided at one side portion of the fixation plate and inserted into the coupling hole like the fixation plate to prevent the fixation plate from being separated.

The base cover coupling plate may have a trapezoidal shape in which an area contacting the edge of the second cover part is provided as a straight line and an area facing the area provided as the straight line is provided to be inclined.

The fixation plate may be provided in a parallelogram shape in which a facing side contacting the base cover coupling plate is provided to be inclined and has a pair of inclined facing sides.

The coupling hole may be provided to be inclined on a left wall and a right wall.

The second cover part may include a second cover plate extending toward a first cover plate of the first cover part from a rear wall of the box body, a second cover coupling plate extending to bent on the second cover plate and covering the first cover plate, and the insertion coupling plate extending on the second cover coupling plate and fitted and coupled to the first cover coupling hole.

The second cover part may further include a fitting cutout portion provided at an area contacting the insertion coupling plate and the second cover coupling plate.

The block portion may include a first block plate extending on the side wall of the box body and bent vertically to the side wall, a second block plate extending on an end portion of the first block plate and vertically bent and having a lower end portion supported on a bottom portion of the box body, a third block plate extending on the end portion of the second block plate and bent to the side wall and contacting the bottom portion of the box body, and a block fixation plate provided at an area contacting the second block plate and the third block plate and fitted and coupled to a coupling hole provided at the bottom portion of the box body.

The block portion may further include a block portion hole provided to be in communication with the first block plate and the second block plate and inserted with a reinforcement plate.

Further, another exemplary embodiment of the present invention provides an eco friendly tapeless packaging box including: a box body in which one side portion is opened; and a cover part covering an opened area of the box body, in which the cover part includes a cover coupling portion fitted and coupled to a coupling hole provided at a wall portion of a box body.

According to exemplary embodiments of the present invention, first, since a cover part is divided into two areas to be fitted and coupled to each other, and a cover coupling portion of the cover part is fitted to a coupling hole provided in a wall of a box body, the box can be combined without a separate taping or stapling operation.

Second, since the cover part divided into two areas which are fitted and coupled to each other is supported by a block portion and coupled to a wall portion of a box body by the cover coupling portion, coupling stability of the cover part and extinction coefficient of the cover part which is divided and fitted and coupled can be structurally reinforced.

Third, when the cover part divided into a first cover part and a second cover part, which are fitted and coupled to each other, a second cover coupling plate of the second cover part is provided to be bent from a second cover plate, thereby conveniently coupling an insertion coupling plate to a first cover coupling hole.

Fourth, when the insertion coupling plate is fitted and coupled to the first cover coupling hole to a fitting cut portion provided at extinction coefficient where the insertion coupling plate of the second cover part and the second cover coupling plate contact each other, the insertion coupling plate and the first cover coupling hole are engaged to each other to maintain coupling force between the insertion coupling plate and the first cover coupling hole.

Fifth, a fixation plate of the cover coupling portion is provided in a parallelogram shape having a pair of inclined facing surfaces and a coupling hole provided on a side wall of the box body is provided to be inclined, thereby conveniently fitting and coupling the cover coupling portion.

Sixth, since a separation prevention plate of the cover coupling portion is inserted into and suspended and supported on the coupling hole provided to be inclined on the side wall of a main body of a box so that the cover coupling portion is not easily separated when the cover coupling portion is coupled to the coupling hole.

Seventh, the box body can be more stably protected from external impact by a pair of block portions provided inside the box body.
