Abstract
Abstract A container made of thermoplastic material such as PET includes a bottom portion, a neck portion, and an intermediate body portion including at least two circumferential rows of panels for providing controlled volumetric reduction of the container. A land separates each adjacent pair of panels in each row. The rows of panels are staggered with respect to each other such that the lands of one row are vertically aligned with the panels of any adjacent row. The design distributes circumferentially the vertical and horizontal support for any label applied to the label panel of the container while still providing the desired panel movement in response to the existence of a partial vacuum within the container due to hot filling.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
75 words
A container made of thermoplastic material comprising: a bottom portion, a neck portion, and an intermediate body portion including at least two circumferential rows of panels including means for providing controlled volumetric reduction of the container, a land separating each adjacent pair of panels in each row, the rows of panels being staggered with respect to each other such that the lands of one row are vertically aligned with the panels of any adjacent row.
Claim 2
Dependent Claim
75 words
A container made of thermoplastic material comprising: a bottom portion, a neck portion, and an intermediate body portion including at least two circumferential rows of panels including means for providing controlled volumetric reduction of the container, a land separating each adjacent pair of panels in each row, the rows of panels being staggered with respect to each other such that the lands of one row are vertically aligned with the panels of any adjacent row.
Claim 3
Dependent Claim
24 words
The container of claim 1 further comprising a circumferential band separating each of the at least two circumferential rows of panels from each other.
Claim 4
Dependent Claim
13 words
The container of claim 2 wherein the circumferential band includes a circumferential rib.
Claim 5
Dependent Claim
20 words
The container of claim 1 wherein each of the panels of each row are of equal vertical and horizontal dimension.
Claim 6
Dependent Claim
13 words
The container of claim 4 wherein each of the panels are generally square.
Claim 7
Dependent Claim
19 words
The container of claim 1 wherein each of the panels of each row are generally planar in transverse cross-section.
Claim 8
Dependent Claim
32 words
The container of claim 1 wherein the body portion comprises a lower generally cylindrical portion and an upper shoulder portion, the rows of panels being confined to the lower generally cylindrical portion.
Claim 9
Dependent Claim
40 words
The container of claim 7 wherein each of the panels of each row comprises a generally planar central section and outwardly sloping sections joining the upper and lower boundaries of the generally planar central section to the generally cylindrical portion.
Claim 10
Dependent Claim
21 words
The container of claim 7 further comprising a circumferential rib separating the upper shoulder portion and the lower generally cylindrical portion.
Claim 11
Dependent Claim
12 words
The container of claim 1 wherein said thermoplastic material is polyethylene terephthalate.
Claim 12
Dependent Claim
111 words
A container made of thermoplastic material especially adapted for hot filling comprising: a bottom portion, a neck portion, and a generally cylindrical intermediate body portion including at least two circumferential rows of panels including means for providing controlled volumetric reduction of the container in response to the presence of a partial vacuum within the container, a land separating each adjacent pair of panels in each row, a circumferential band separating each of the at least two circumferential rows of panels from each other, the rows of panels being staggered with respect to each other such that the lands of one row are vertically aligned with the panels of any adjacent row.
Claim 13
Dependent Claim
111 words
A container made of thermoplastic material especially adapted for hot filling comprising: a bottom portion, a neck portion, and a generally cylindrical intermediate body portion including at least two circumferential rows of panels including means for providing controlled volumetric reduction of the container in response to the presence of a partial vacuum within the container, a land separating each adjacent pair of panels in each row, a circumferential band separating each of the at least two circumferential rows of panels from each other, the rows of panels being staggered with respect to each other such that the lands of one row are vertically aligned with the panels of any adjacent row.
Claim 14
Dependent Claim
41 words
The container of claim 11 wherein each of the panels of each row comprises a generally planar central section and outwardly sloping sections joining the upper and lower boundaries of the generally planar central section to the generally cylindrical body portion.
Claim 15
Dependent Claim
60 words
The container of claim 11 further comprising circumferential land portions at the upper margin of the uppermost row of panels and at the lower margin of the lowermost row of panels, and wherein the circumferential land portions, the lands in each row, and the circumferential bands between rows define a label supporting region within the general cylindrical intermediate body portion.
