Description

TECHNICAL FIELD



[0001] Exemplary embodiments according to the present disclosure relate to a box holder, and more particularly, to a box holder capable of packing products and items in a clean and safe manner without damaging a box during the packing of the products and the items into the box.

BACKGROUND ART



[0002] Conventionally, papers of various kinds (corrugated cardboard, cardboard, etc.) are manufactured into a planar sheet of packaging box which is then folded into a three-dimensional packaging box in sequence. After a product is put in the three-dimensional packaging box, the box is sealed at the top and bottom by machine or a simple jig using a steel fixing pin such as a stapler pin and shipped. To unpack the shipped packaging box, at least 12 pins need to be removed from the top and bottom of the box. However, it is inconvenient to remove the stapler pins. Moreover, because the pins are sharp, hand may be injured and the surface of the packaging box may be damaged during the removal of the pins, making it impossible to reuse the box. While the top and bottom of the box may be sealed by an adhesive, this could also damage the packaging box as the surface of the packaging box may be torn off during the unpacking of the box.

[0003] As shown in FIG. 1, a packaging box (10) generally has a first cover (11) and a second cover (12) on an upper surface or a lower surface, the first and second covers facing each other to form an inlet. Once product is received through the inlet, the first cover (11) and the second cover (12) of the packaging box (10) are folded together at the inlet to seal the box. The inlet is sealed with a tape (20, see FIG. 2) along edges (111, 112) to sealingly pack the box. However, as shown in FIG. 3, when a tape (21) is applied along edges (111, 112) of the first cover (11) and the second cover (12), the edges (111, 112) may be detached to prevent a complete sealing of the box. To solve this problem, most users would wind the tape (21) around the box while pressing down the edges (111, 112) of the first cover (11) and the second cover (12) with a foot or hand.

[0004] Korean Utility Model Publication No. 20-0393769 (hereafter, referred to as "Prior Art Document 1") discloses a device for folding a packaging box manufactured from papers of various kinds (corrugated cardboard, cardboard, etc.) to be provided in the form of a planar sheet which is then folded into a three-dimensional packaging box in sequence. Korean Patent Publication No. 10-0564806 (hereinafter, referred to as "Prior Art Document 2") discloses a tape attaching device. According to Prior Art Documents 1 and 2, a packaging box provided in the form of a planar sheet is folded into a three-dimensional packaging box in sequence. After an item is put in the three-dimensional packaging box, the box is taped using the tape attaching device.

[0005] However, it is not economically feasible to purchase and store such expensive machine as disclosed in Prior Art Documents 1 and 2, unless it is necessary to handle a large number of packaging boxes at home, post offices, and general offices, etc.

BEST MODE(S) FOR CARRYING OUT THE INVENTION



[0030] Hereinafter, the aforesaid and additional aspects of the present disclosure will be described in detail in exemplary embodiments with reference to the accompanied drawings to enable one of ordinary skill in the art to readily carry it out.

[0031] In the present disclosure, the material of a packaging box includes paper (corrugated cardboard, cardboard, etc.), plastic or boards. A packaging box provided in the form of a planar sheet is folded into a three-dimensional packaging box in sequence, so as to allow a product to be placed in the three-dimensional packaging box.

[0032] A box holder is a device for pressing an upper surface and respective side surfaces of a polyhedral packaging box towards the central portion of the box. A box holder may include rubber or synthetic resins having good elasticity, or commonly known metals. If a box holder is made of an elastic material, the box holder may be provided to be smaller than a standard size of a packaging box. The packaging box (polyhedron) has respective side surfaces that are pressed towards the central portion thereof, while an upper surface of the box is pressed down (central portion).

[0033] If a box holder is made of a heavy material such as a metal, the pressing force of legs of the box holder is imparted to allow respective side surfaces of the packaging box to face toward the central portion of the box, while an upper surface of the packaging box is pressed down by the self-weight of the box holder.

[0034] Referring to FIG. 4, a box holder (40) according to a first exemplary embodiment of the present disclosure includes two horizontal bars (41, 42) spaced apart from each other at a predetermined interval; first bent portions (411, 412, 421, 422) bendingly extending from the horizontal bars (41, 42); and first support members (43, 44) to connect the first bent portions (411, 412, 421, 422). The box holder (40) according to a first exemplary embodiment of the present disclosure includes joint portions (45, 46, 48, 49) engaged with the two horizontal bars (41, 42); second bent portions (451, 461, 481, 491) bendingly extending from the joint portions (45, 46, 48, 49); and second support members (47, 50) to connect the second bent portions (451, 461, 481, 491).

[0035] According to the first exemplary embodiment of the present disclosure, the horizontal bar (41) may be integrally provided with the bent portions (411, 412) at opposite ends of the horizontal bar (41). The horizontal bar (42) may be integrally provided with the bent portions (421, 422) at opposite ends of the horizontal bar (42). The joint portions (45, 46, 48, 49) may be integrally provided with the second bent portions (451, 461, 481, 491), while one end of each of the joint portions may be coupled to the horizontal bars (41, 42) by welding, etc.

[0036] A set of the horizontal bar (41) and the bent portions (411, 412) at the opposite ends thereof provides a transverse bent member. A set of the joint portion (45) and the second bent portion (451) provides a longitudinal bent member. The first exemplary embodiment of the present disclosure includes two transverse bent members disposed parallel to each other; a pair of longitudinal bent members vertically coupled to the transverse bent members to extend therefrom in opposite directions, respectively; and a support member to connect ends of a pair of adjacent bent members.

[0037] Although the first exemplary embodiment of the present disclosure provides a pair of transverse bent members and two pairs of longitudinal bent members, it is possible to have a simpler structure, for example, a pair of longitudinal bent members vertically coupled to a central portion of a single transverse bent member to extend therefrom in opposite directions, and a support member disposed vertically to a free end of the respective bent members.

[0038] Referring to FIG. 5, a user folds a first cover (11) and a second cover (12) to face each other at an inlet of a packaging box (10), and slowly fits a box holder (40) according to the first exemplary embodiment of the present disclosure onto a top surface of the packaging box (10). As the box holder (40) presses the packaging box (10) to allow respective side surfaces (13) of the packaging box (10) to face toward a central portion of the packaging box (10), the box holder (40) presses down the first cover (11) and the second cover (12) by the self-weight of the box holder (40), thereby providing a complete sealing of the packaging box. The box holder holds the covers of the box in place so that the user does not need to hold or push the box with hands when packing, thereby freeing the hands. The user may have the packaging box (10) assembled by the box holder (40) according to the first exemplary embodiment of the present disclosure delivered to a desired location via a courier. Each of the support members (43, 44, 47, 50) serves to increase the force of supporting the respective side surfaces (13) of the packaging box (10) so as to gather the side surfaces toward the central portion of the packaging box (10).

[0039] Referring to FIG. 6, the user may attach auxiliary fixing means, for example, a tape (21), along an edge of the box at which the first cover (11) and the second cover (12) of the packaging box (10) are joined together. Referring to FIG. 7, the user may dissemble the box holder (40) from the packaging box (10) with the tape (21) attached thereto as auxiliary fixing means and have the packaging box (10) delivered to a desired location via a courier. To this end, a tape cutter (not shown) may be attached or provided on a side of the box holder (40).

[0040] In contrast to the example shown in FIG. 6, the packaging box (10) may be transported while having the tape (21) and the box holder (40) mounted thereon.
