Abstract

A packaging box (10) includes a pair of lids (2, 3), and the pair of lids (2, 3) have tongues (2b, 3b) extending from their heads and lid gluing portions (2c, 3c) arranged in specific areas on the outer surfaces of these tongues (2b, 3b). A body (1) of the packaging box (10) has a pair of body gluing portions (1f, 1g) individually glued to the lid gluing portions (2c, 3c) and at least one transverse split-open portion (5) for guiding a fracture in a side face of the packaging box (10). Both open-side ends (1e) have side-end split-open portions (6, 7) arranged so as to surround the body gluing portions (1f, 1g). Thus, even if the tongues provided at the heads of the lids are glued to side plates, the packaging box can be easily and accurately split and spread.

Claims

1. A packaging box with opposite inner and outer surfaces, the inner surface defining an indication portion to indicate information, the packaging box being configured to be opened and spread flat for accessing the indication portion on the inner surface of the packaging box, the packaging box comprising:

a substantially rectangular tubular body having opposite first and second ends, opposed front and rear plates extending from the first end to the second end of the body, opposite first and second side plates hinged to the front and rear plates and extending from the first end to the second end of the body;

first and second lids joined to the rear plate along creases at the respective first and second ends of the body;

first and second tongues joined to the respective first and second lids along creases at locations on the respective first and second lids opposite the rear plate, the lids being disposed adjacent portions of the front plate facing inwardly on the packaging box;

first and second gluing portions securing the first and second tongues to the front plate at locations spaced inwardly from the first and second side plates of the body;

a side fracture guide extending substantially from the first end to the second end of the body at locations along the front plate substantially adjacent the first side plate;

a substantially U-shaped first end fracture guide formed in portions of the front plate adjacent the first end and substantially surrounding the first gluing portion, the substantially U-shaped first end fracture guide includes a first leg intersecting the first end of the body, a second leg substantially parallel to the first end of the body and a third leg intersecting the first end of the body at a location spaced from the first leg of the first end fracture guide, the first and third legs of the first end fracture guide being substantially parallel to one another and substantially perpendicular to the first end of the body; and

a substantially U-shaped second end fracture guide formed in a portion of the front plate substantially adjacent the second end and surrounding the second gluing portion, the second end fracture guide includes a first leg extending from the second end of the body, a second leg aligned substantially parallel to the second end of the body and a third leg intersecting the second end of the body at a location spaced from the first leg of the second end fracture guide, the first and third legs of the second end fracture guide being substantially parallel to one another and being aligned to extend towards the side fracture guide at farther distances from the second end of the body.

2. A packaging box with opposite inner and outer surfaces, the inner surface defining an indication portion to indicate information, the packaging box being configured to be opened and spread flat for accessing the indication portion on the inner surface of the packaging box, the packaging box comprising:

a substantially rectangular tubular body having opposite first and second ends, opposed front and rear plates extending from the first end to the second end of the body, opposite first and second side plates hinged to the front and rear plates and extending from the first end to the second end of the body;

first and second lids joined to the rear plate along creases at the respective first and second ends of the body;

first and second tongues joined to the respective first and second lids along creases at locations on the respective first and second lids opposite the rear plate, the lids being disposed adjacent portions of the front plate facing inwardly on the packaging box;

first and second gluing portions securing the first and second tongues to the front plate at locations spaced inwardly from the first and second side plates of the body;

a side fracture guide extending substantially from the first end to the second end of the body at locations along the front plate substantially adjacent the first side plate;

a substantially U-shaped first end fracture guide formed in portions of the front plate adjacent the first end and substantially surrounding the first gluing portion; and

a substantially U-shaped second end fracture guide formed in a portion of the front plate substantially adjacent the second end and surrounding the second gluing portion, wherein the substantially U-shaped second end fracture guide has a first leg extending obliquely from the second end of the body towards the side fracture guide, a second leg extending substantially parallel to the second end of the body and away from the side fracture guide and a third leg extending from the second end of the body towards an end of the second leg farthest from the side fracture guide.

3. The packaging box of claim 2, wherein the substantially U-shaped first end fracture guide includes a first leg intersecting the first end of the body, a second leg substantially parallel to the first end of the body and a third leg intersecting the first end of the body at a location spaced from the first leg the first end fracture guide.

4. The packaging box of claim 3, wherein the first and third legs of the first end fracture guide are substantially parallel to one another.
