Abstract
Abstract A packaging and display carton is constructed of first and second sheets of durable, flexible transparent material of a generally rectangular configuration having a double wall cavity packaging chamber formed in one of the sheets with vertically extending wall and a closure cap with a display window formed in the other sheet wherein the outer walls of the packaging chamber and the inner walls of the display cavity have an interference fit for frictionally engaging and sealing the chamber and retaining the part in the closed position by friction and vacuum. An intermediate labeling and display card or sheet is disposed between the two sheets and includes an opening for receiving the walls of the packaging chamber therethrough. Vacuum locking devices in the form of snug fitting protrusions and sockets for holding the sheets together are disclosed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
190 words
A packaging and display carton, said carton comprising: a first substantially rectangular unitary plane sheet of durable flexible material having a first portion thereof shaped to define a packaging chamber and an adjacent plane labeling support surface, said chamber being defined by continuous uninterrupted walls formed of and rising from said first sheet, at least a portion of said wall being a double wall having inner and outer walls connected by an upper inverted U-shaped rim, a second substantially rectangular unitary sheet of durable flexible transparent material shaped to define a closure cavity and display window, said cavity being defined by walls extending upward from the plane surface of said sheet and having substantially the same shape as the outer walls of said packaging chamber and fitting over the walls of said packaging chamber with a snug fit thereby providing a tight fitting sealing engagement with a vacuum lock therebetween, said second sheet including means defining a labeling display window covering said labeling support surface, and a labeling sheet disposed between said first and second sheets and including an opening therethrough through which the walls of said packaging chamber extend.
Claim 2
Dependent Claim
190 words
A packaging and display carton, said carton comprising: a first substantially rectangular unitary plane sheet of durable flexible material having a first portion thereof shaped to define a packaging chamber and an adjacent plane labeling support surface, said chamber being defined by continuous uninterrupted walls formed of and rising from said first sheet, at least a portion of said wall being a double wall having inner and outer walls connected by an upper inverted U-shaped rim, a second substantially rectangular unitary sheet of durable flexible transparent material shaped to define a closure cavity and display window, said cavity being defined by walls extending upward from the plane surface of said sheet and having substantially the same shape as the outer walls of said packaging chamber and fitting over the walls of said packaging chamber with a snug fit thereby providing a tight fitting sealing engagement with a vacuum lock therebetween, said second sheet including means defining a labeling display window covering said labeling support surface, and a labeling sheet disposed between said first and second sheets and including an opening therethrough through which the walls of said packaging chamber extend.
Claim 3
Dependent Claim
32 words
The packaging and display carton of claim 1 wherein said labeling sheet contains a list of potential articles for displaying in the chamber of said package, and indicia indicating the article displayed.
Claim 4
Dependent Claim
75 words
The packaging and display carton of claim 1, including vacuum locking means formed on said first and second sheets, spaced from said packaging chamber and said closure cavity, said locking means comprising a protrusion formed on one of said sheets and a socket formed on the other of said sheets, said protrusion dimensioned for insertion into said socket with tight fitting sealing engagement for thereby forming a vacuum lock between said first and second sheets.
Claim 5
Dependent Claim
60 words
The packaging and display carton of claim 1, including vacuum locking means formed on said first and second sheets, said locking means comprising a protrusion formed on one of said sheets and a socket formed on the other of said sheets, said protrusion dimensioned for insertion into said socket with tight fitting sealing engagement for thereby forming a vacuum lock.
Claim 6
Dependent Claim
30 words
The packaging and display carton of claim 1 wherein said packaging chamber is substantially cylindrical in configuration; said closure cavity is substantially cylindrical and includes a dome shaped display window.
Claim 7
Dependent Claim
28 words
The packaging and display carton of claim 1 wherein said packaging chamber includes a plurality of compartments defined by a plurality of walls extending upward in said compartment.
Claim 8
Dependent Claim
24 words
The packaging and display carton of claim 6 wherein said closure means includes depression formed therein for receiving the upper edge of said walls.
Claim 9
Dependent Claim
231 words
A packaging and display carton, said carton comprising: a first substantially rectangular unitary plane sheet of durable flexible material having a first portion thereof shaped to define a packaging chamber and an adjacent plane labeling support surface, said chamber being defined by continuous uninterrupted walls formed of and rising from said first sheet, at least a portion of said wall being a double wall having inner and outer walls connected by an upper inverted U-shaped rim, a second substantially rectangular unitary sheet of durable flexible transparent material shaped to define a closure cavity and display window, said cavity being defined by walls extending upward from the plane surface of said sheet and having substantially the same shape as the outer walls of said packaging chamber and extending over the walls of said packaging chamber with a snug fit thereby providing a tight fitting frictional sealing engagement and thereby defining a vacuum lock therebetween so that said first and second sheets are held together by said vacuum lock, and further vacuum locking means formed on said first and second sheets, said further vacuum locking means comprising a substantially cylindrical protrusion formed on one of said sheets and a substantially cylindrical socket formed on the other of said sheets, said protrusion being inserted into said socket in tight fitting sealing engagement thereby forming a further vacuum lock between said first and second sheets.
Claim 10
Dependent Claim
231 words
A packaging and display carton, said carton comprising: a first substantially rectangular unitary plane sheet of durable flexible material having a first portion thereof shaped to define a packaging chamber and an adjacent plane labeling support surface, said chamber being defined by continuous uninterrupted walls formed of and rising from said first sheet, at least a portion of said wall being a double wall having inner and outer walls connected by an upper inverted U-shaped rim, a second substantially rectangular unitary sheet of durable flexible transparent material shaped to define a closure cavity and display window, said cavity being defined by walls extending upward from the plane surface of said sheet and having substantially the same shape as the outer walls of said packaging chamber and extending over the walls of said packaging chamber with a snug fit thereby providing a tight fitting frictional sealing engagement and thereby defining a vacuum lock therebetween so that said first and second sheets are held together by said vacuum lock, and further vacuum locking means formed on said first and second sheets, said further vacuum locking means comprising a substantially cylindrical protrusion formed on one of said sheets and a substantially cylindrical socket formed on the other of said sheets, said protrusion being inserted into said socket in tight fitting sealing engagement thereby forming a further vacuum lock between said first and second sheets.
