Description

Box assembly with inner case for preventing separate

The present invention is formed of a front opening is formed on the front surface, the outer case having an empty hexahedral shape inside, and the upper case is formed on the upper surface and the inner case is inserted into the outer case through the front opening, the outer case and The inner case is made of paper, and the box assembly of the double structure is assembled in the state of bending in the development state, the inner case is formed by forming protrusions on the inner side wall of the outer case, the locking projections on the wall of both sides of the inner case The present invention relates to a double packaging box assembly having a detachable inner case to prevent the outer case from being separated.

In general, a variety of members have been used in the wood or synthetic resin and metal drawer cabinet to be opened and closed by sliding in the interior to prevent the drawer of the interior from leaving the outside.

These components are applied to limit the rail to prevent further movement.

On the other hand, a number of known techniques for drawing a developed view on a flat paper, and folding or cutting a portion of the developed view to form a double structure such as a drawer cabinet so that the inner case is exposed out of the outer case in a sliding manner.

For example, the "drawer-type packing box" (Korean Patent Publication No. 10-1003527) is formed in the front and the opening is formed a space for receiving the article, the inner box and one of the gripping means is attached to both sides An opening is formed in a side surface so that the inner box is inserted and received, and a structure in which a through hole through which one of the holding means penetrates is formed on a surface facing the opening formed in the one side.

The configuration is a configuration in which the through-hole is formed so that the string serving as a handle can be inserted when assembling the packaging box.

However, the conventional sliding packaging boxes of the dual structure as described above do not have a separate means for preventing the inner case from leaving the outer case there was a problem such as the loss of contents due to the separation of the inner case.

In relation to the solution of this problem, the "slide-type packaging box" (Korean Patent Publication No. 10-971682) is formed with a groove on one side of the outer box, the handle of the inner box is fitted into the groove on one side of the outer box to protrude. A configuration is disclosed in which the handle is prevented from detaching by making it possible.

However, the case of the box has a problem that the manufacturing process is not simple because the handle of the synthetic resin material must be installed separately in the inner case.

In addition, in the case of a box that does not require a handle there was a problem that is difficult to apply.
