Abstract

A pull type packing box comprises inner and outer containers. The outer container is a tube type box for receiving the inner container like a drawer. The outer container is provided with handles and performs the function of a shopping bag. As the outer container partially exposes a head portion of the inner container, a user can grasp the head portion to open the inner container, and information about an article can be printed on the exposed head portion. The strength of the mouth part of the outer container is increased so that the mouth part does not bend and the outer appearance of the packing box is not deteriorated. The outer container generates appropriate frictional force so that the drawer is not excessively opened and closed. The outer container includes a stopper for preventing the drawer from being separated from the outer container when opening the inner

Claims

1. A pull type packing box suitable for packing an article, manufactured by cutting a paperboard in the shape of a developed box, folding corners of the developed box, and pasting connection parts, the packaging box comprising:

an outer container having four wall parts (11, 12, 13 and 14) and a rear wall part (15) which form the shape of a quadrangular tube, defining a mouth part (16) through which an inner container (30) is inserted like a drawer, and possessing handles (17) provided adjacent to the mouth part (16) to perform the function of a shopping bag;

the inner container (30) having four outer wall parts (31, 32, 33 and 34), four inner wall parts (35, 36, 37 and 38) and a bottom wall part (39) which form the shape of a quadrangular container, accommodating an article support (61) for displaying at least one article, and inserted through the mouth part (16) of the outer container (10) to be opened and closed like a drawer;

mouth overlapping parts (21, 22, 23 and 24) formed by extending and inwardly bending the four wall parts of the outer container (10) at the mouth part (16) of the outer container (10) through which the inner container (30) is inserted, for reinforcing strength of the mouth part (16);

a stopper (42) formed by a free end of one mouth overlapping part (21) of the mouth overlapping parts, and elastically detached from an upper wall part of the outer container (10) to define a gap (41), so that the stopper (42) can be brought into contact with an upward projection (40) of the inner container (30) when the inner container (30) is opened; and

the upward projection (40) formed by the rear wall of the inner container (30) to be brought into contact with the stopper (42) of the outer container (10).

2. The pull type packing box as set forth in claim 1, further comprising:

inclined parts (25) formed at both sides of the mouth part (16) of the outer container (10);

a touch part (44) formed on the inner container (30) and exposed outside of the outer container (10) due to presence of the inclined parts (25), even when the inner container (30) is closed; and

a grip part (45) connected with edges of the outer and inner wall parts (31 and 35) of the inner container (30) to form three sides of a rectangular tube , wherein the grip part (45) forms the touch part (44) exposed outside of the outer container (10).

3. The pull type packing box as set forth in claim 1, wherein perforated lines (27) for insertion of fingers are formed on the front outer wall part (31).

4. The pull type packing box as set forth in claim 1, wherein three remaining mouth overlapping parts (22, 23 and 24) are detached from the corresponding wall parts of the outer container (10) and are brought into elastic contact with the inner container (30) to suppress excessive opening and closing operations of the inner container (30).

5. The pull type packing box as set forth in claim 4, wherein each of the handles (17) has two head portions (19), each of which is inserted through a hole (18) which is defined in the outer container (10), to be retained around the hole (18) on an inner surface of the outer container (10), and functions to maintain the gap (41) between the stopper (42) and the outer container (10).
