Abstract
Abstract A one-piece box blank is cut from a single sheet with creases and score lines dividing the box blank into a receptacle section, a hinge section and a cover section. The cover and receptacle sections both have side and front flaps. The front flaps and hinge section are proportioned such that the receptacle front flap is not totally overlapped by the cover front flap when the box is closed. The depth of the receptacle side flaps adjacent the hinge section is less than the depth of the hinge section. The spaced, scored fold lines separating the side flaps from the cover and the receptacle sections are straight lines, converging from the front flap of the cover to the front flap of the receptacle. If the box is wrapped corner notches are preferably cut in both the one-piece box blank and in a one-piece wrap. The wrap and the blank are combined as they pass through a conventional wrapping machine. When the wrap and box blank are in tray configuration in the wrapping machine, the hinge cuts are incised in either the wrap or in both the wrap and the box blank by added machine components. In the closed box the partially exposed receptacle front flap affords an overlying cover flap edge for opening the box.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
297 words
A one-piece folded box comprising a receptacle section having a bottom panel, a pair of spaced side flaps, a front flap and fold lines at the point of connection of said side flaps and front flap to said bottom panel; means fixing said front flap to said side flaps in folded and joined configuration at their mutual corners; a cover section having a lid panel, a pair of spaced side flaps, a front flap and fold lines at the point of connection of said side flaps and said front flap to said lid panel; means fixing said front flap and said side flaps in folded and joined configuration at their mutual corners; said side flaps of both said receptacle section and said cover section having a free edge opposite their respective fold lines; a hinge section including a hinge wall containing a pair of spaced fold lines each defining an active hinge, said hinge section connecting the receptacle and cover sections at said active hinges; means for reducing contact at closure between the cover and the receptacle side flaps to relieve that contact pressure resistance against maintaining proper closure of said cover section with respect to said receptacle section, said last-named means comprising receptacle side flaps having a substantial portion of the depth between said free edge thereof and the respective fold lines of the receptacle section less than the between the fold lines of said hinge section; and means for arresting the closing cover short of enveloping the front flap of the receptacle section, said means for arresting comprising a hinge section having a greater depth than either of the front flaps, and at least one stop tab having a fold line connected to any one of said flaps, said bottom panel and said lid panel.
Claim 2
Dependent Claim
297 words
A one-piece folded box comprising a receptacle section having a bottom panel, a pair of spaced side flaps, a front flap and fold lines at the point of connection of said side flaps and front flap to said bottom panel; means fixing said front flap to said side flaps in folded and joined configuration at their mutual corners; a cover section having a lid panel, a pair of spaced side flaps, a front flap and fold lines at the point of connection of said side flaps and said front flap to said lid panel; means fixing said front flap and said side flaps in folded and joined configuration at their mutual corners; said side flaps of both said receptacle section and said cover section having a free edge opposite their respective fold lines; a hinge section including a hinge wall containing a pair of spaced fold lines each defining an active hinge, said hinge section connecting the receptacle and cover sections at said active hinges; means for reducing contact at closure between the cover and the receptacle side flaps to relieve that contact pressure resistance against maintaining proper closure of said cover section with respect to said receptacle section, said last-named means comprising receptacle side flaps having a substantial portion of the depth between said free edge thereof and the respective fold lines of the receptacle section less than the between the fold lines of said hinge section; and means for arresting the closing cover short of enveloping the front flap of the receptacle section, said means for arresting comprising a hinge section having a greater depth than either of the front flaps, and at least one stop tab having a fold line connected to any one of said flaps, said bottom panel and said lid panel.
Claim 3
Dependent Claim
244 words
A one-piece folded box comprising a receptacle section having a bottom panel, a pair of spaced side flaps, a front flap and fold lines at the point of connection of said side flaps and front flap to said bottom panel; means fixing said front flap to said side flaps in folded and joined configuration at their mutual corners; a cover section having a lid panel, a pair of spaced side flaps, a front flap and fold lines at the point of connection of said side flaps and said front flap to said lid panel; means fixing said front flap and said side flaps in folded and joined configuration at their mutual corners; said side flaps of both said receptacle section and said cover section having a free edge opposite their respective fold lines; a hinge section including a hinge wall containing a pair of spaced fold lines each defining an active hinge, said hinge section connecting the receptacle and cover sections at said active hinges; and means for reducing contact at closure between the cover and the receptacle side flaps to relieve that contact pressure resistance against maintaining proper closure of said cover section with respect to said receptacle section wherein the means for reducing contact pressure comprises receptacle side flaps having a substantial portion of the depth between said free edge thereof and the respective fold lines of the receptacle section less than the depth between the fold lines of said hinge section.
Claim 4
Dependent Claim
244 words
A one-piece folded box comprising a receptacle section having a bottom panel, a pair of spaced side flaps, a front flap and fold lines at the point of connection of said side flaps and front flap to said bottom panel; means fixing said front flap to said side flaps in folded and joined configuration at their mutual corners; a cover section having a lid panel, a pair of spaced side flaps, a front flap and fold lines at the point of connection of said side flaps and said front flap to said lid panel; means fixing said front flap and said side flaps in folded and joined configuration at their mutual corners; said side flaps of both said receptacle section and said cover section having a free edge opposite their respective fold lines; a hinge section including a hinge wall containing a pair of spaced fold lines each defining an active hinge, said hinge section connecting the receptacle and cover sections at said active hinges; and means for reducing contact at closure between the cover and the receptacle side flaps to relieve that contact pressure resistance against maintaining proper closure of said cover section with respect to said receptacle section wherein the means for reducing contact pressure comprises receptacle side flaps having a substantial portion of the depth between said free edge thereof and the respective fold lines of the receptacle section less than the depth between the fold lines of said hinge section.
