Abstract
Abstract A sleeve carton having flare lip panels is disclosed. A sleeve carton may be formed with flaring lip panels on the inner edge of the sleeve entrance. The lip panels bulge into the entrance, but are easily compressed. The inner edge of the lip panels catches on flat packaged items being withdrawn from the sleeve. The flaring lip panels then act as a latch for inserted flat or similar flat packages loaded in the sleeve.

Total Claims: 19
Claim 1
Independent Claim
262 words
A sleeve carton comprising: (a) a hollow sleeve with at least three rectangular sleeve panels, each sleeve panel having two parallel and opposite seam edges and at least one opening edge intermediate the respective seam edges, each sleeve panel coupled along the respective seam edges to two respective adjacent sleeve panels thereby forming sleeve seams between the adjacent sleeve panels with the respective opening edges adjacent and coplanar thereby defining a sleeve with an enclosed cavity having an axis parallel to the sleeve panels, and parallel to the sleeve seams, and at least one open end defined by the coplanar opening edges one each from the respective sleeve panels, and (b) at least one lip panel positioned in the enclosed cavity, hinged on a first lip panel edge to a first of the respective sleeve panels along the opening edge of the respective first sleeve panel, having a second edge of the flaring lip panel transverse to the first lip panel edge, and contacting a respective first sleeve seam formed between the first sleeve panel and an adjacent second of the respective sleeve panels, and a third edge of the flaring lip panel opposite the second edge of the flaring lip panel transverse to the first lip panel edge, and contacting a respective second seam formed between the first sleeve panel and an adjacent third of the respective sleeve panels, to receive a compressive force from the second sleeve panel and third sleeve panel, the lip panel thereby flaring into the enclosed cavity and away from the adjacent respective first sleeve panel.

Dependent Claim
262 words
A sleeve carton comprising: (a) a hollow sleeve with at least three rectangular sleeve panels, each sleeve panel having two parallel and opposite seam edges and at least one opening edge intermediate the respective seam edges, each sleeve panel coupled along the respective seam edges to two respective adjacent sleeve panels thereby forming sleeve seams between the adjacent sleeve panels with the respective opening edges adjacent and coplanar thereby defining a sleeve with an enclosed cavity having an axis parallel to the sleeve panels, and parallel to the sleeve seams, and at least one open end defined by the coplanar opening edges one each from the respective sleeve panels, and (b) at least one lip panel positioned in the enclosed cavity, hinged on a first lip panel edge to a first of the respective sleeve panels along the opening edge of the respective first sleeve panel, having a second edge of the flaring lip panel transverse to the first lip panel edge, and contacting a respective first sleeve seam formed between the first sleeve panel and an adjacent second of the respective sleeve panels, and a third edge of the flaring lip panel opposite the second edge of the flaring lip panel transverse to the first lip panel edge, and contacting a respective second seam formed between the first sleeve panel and an adjacent third of the respective sleeve panels, to receive a compressive force from the second sleeve panel and third sleeve panel, the lip panel thereby flaring into the enclosed cavity and away from the adjacent respective first sleeve panel.
Claim 3
Dependent Claim
255 words
A carton blank for a flaring lip sleeve carton comprising: a flat foldable material separated into rectangular panels including (a) a first row of at least three adjacent sleeve panels separated by parallel seam edges, each sleeve panel having at least one opening edge on a similar end of the respective sleeve panel, and intermediate the seam edges of the respective sleeve panel, the opening edges being colinear to define a common main fold line perpendicular to the seam edges. (b) means for coupling a first end of the row of sleeve panels to an opposite second end of the row of sleeve panels to form a sleeve, (c) at least one flaring lip panel, hinged along a first flaring lip panel edge to the opening edge of a respective first of the sleeve panels, having a second edge transverse to the opening edge of the respective first sleeve panel, and a third edge transverse to the opening edge of the respective first sleeve panel and opposite the second flaring lip panel edge, (d) a first compressive force transmitting means coupled to the second flaring lip panel edge for transmitting a compressive force to the flaring lip panel in the direction of the third flaring lip panel edge to cause the flaring lip panel to arc, and (e) a second compressive force transmitting means coupled to the third flaring lip panel edge for transmitting a compressive force in the direction of the second flaring lip panel edge to cause the flaring lip panel to arc.
Claim 4
Dependent Claim
255 words
A carton blank for a flaring lip sleeve carton comprising: a flat foldable material separated into rectangular panels including (a) a first row of at least three adjacent sleeve panels separated by parallel seam edges, each sleeve panel having at least one opening edge on a similar end of the respective sleeve panel, and intermediate the seam edges of the respective sleeve panel, the opening edges being colinear to define a common main fold line perpendicular to the seam edges. (b) means for coupling a first end of the row of sleeve panels to an opposite second end of the row of sleeve panels to form a sleeve, (c) at least one flaring lip panel, hinged along a first flaring lip panel edge to the opening edge of a respective first of the sleeve panels, having a second edge transverse to the opening edge of the respective first sleeve panel, and a third edge transverse to the opening edge of the respective first sleeve panel and opposite the second flaring lip panel edge, (d) a first compressive force transmitting means coupled to the second flaring lip panel edge for transmitting a compressive force to the flaring lip panel in the direction of the third flaring lip panel edge to cause the flaring lip panel to arc, and (e) a second compressive force transmitting means coupled to the third flaring lip panel edge for transmitting a compressive force in the direction of the second flaring lip panel edge to cause the flaring lip panel to arc.
