Abstract

Claims (38)

1. A cartridge, comprising:

a front wall, a rear wall, a pair of side walls, and a base that is opposite a neck;

a shoulder section that is located at an outlet end, the shoulder section extending at an angle from the neck to each of the front wall, the rear wall, and the pair of side walls;

an open mouth extending through the neck to an inner volume;

a vertical axis extending centrally through the cartridge; and

a plurality of creases, wherein an upper crease and a lower crease each extend along the front wall and the rear wall perpendicular to the vertical axis and between the pair of side walls, wherein the upper crease is located a first distance from the shoulder section and the lower crease is located a second distance from the base, wherein the second distance is greater than the first distance, and wherein the upper and lower creases are arranged to be offset from an even spacing between the base and the shoulder section of the cartridge in a direction toward the outlet end.

2. The cartridge of claim 1 , wherein the cartridge includes at least one opaque portion.

3. The cartridge of claim 1 , wherein the cartridge includes at least one translucent portion.

4. The cartridge of claim 1 , wherein a rib extends along the shoulder between the neck and one of the pair of side walls.

5. The cartridge of claim 1 , wherein the plurality of creases define a collapse pattern and the cartridge is configured to collapse according to the collapse pattern.

6. A cartridge for use within a dispenser, the cartridge comprising:

an outlet end, a base end opposite the outlet end, a front wall, a rear wall, and two side walls,

wherein the outlet end has a shoulder and an annular collar that extends about an axially extending neck that defines an opening into an inner volume of the cartridge,

wherein the front, rear and two side walls extend from the outlet end to the base end,

wherein the front wall and the rear wall include a plurality of fold lines that are arranged to be offset from an even spacing between the base end and the shoulder of the cartridge in a direction toward the outlet end,

wherein a vertical plane is disposed centrally between the two side walls and intersects the front wall and the rear wall,

wherein the two side walls include a first side wall and a second side wall each carrying a respective first and second valley,

wherein each of the first valley and the second valley is bordered by a top peripheral edge, a front peripheral edge, a rear peripheral edge, and a bottom peripheral edge,

wherein a front panel extends from the front peripheral edge toward a vertical fold line, a rear panel extends from the rear peripheral edge to the vertical fold line, an upper panel extends from the top peripheral edge to the vertical fold line, and a lower panel extends from the bottom peripheral edge to the vertical fold line,

wherein the vertical fold line is located closer to the vertical plane than the top, front, rear, and bottom peripheral edges,

wherein the vertical fold line extends between an upper junction and a lower junction, the upper junction being connected to an upper pair of angled fold lines and the lower junction being connected to a lower pair of angled fold lines,

wherein the upper panel extends between the upper pair of angled fold lines, the lower panel extends between the lower pair of angled fold lines, and wherein the upper panel defines a surface area that is less than a surface area of the lower panel, and

wherein the upper junction is located closer to the top peripheral edge than the lower junction is located to the bottom peripheral edge.

7. The cartridge of claim 6 , wherein each of the upper panel and the lower panel is substantially triangular-shaped and has a substantially planar surface.

8. The cartridge of claim 6 , wherein on collapsing of the cartridge under a vacuum applied to withdraw fluid from the opening, the front wall and rear wall are drawn toward each other, and the first side wall and the second side wall fold along respective upper and lower pairs of fold lines and vertical fold lines.

9. A cartridge, comprising:

an inner volume;

a neck extending from a shoulder portion at an outlet end;

a front wall opposite a rear wall and a first wall opposite a second wall; and

a base,

wherein the front wall and the rear wall include a plurality of creases that are arranged to be offset from an even spacing between the base and shoulder portion of the cartridge in a direction toward the outlet end,

wherein the neck defines an opening that is in communication with the inner volume, and

wherein the cartridge is configured to be inserted into a dispenser having a front panel that is opaque and a body that includes at least two visible light transmission (VLT) values, each of the VLT values being greater than 5%.

10. The cartridge of claim 9 , wherein the cartridge has a VLT value greater than 5%.

11. The cartridge of claim 9 , wherein when the cartridge is inserted into the dispenser a first portion of the cartridge is configured to be visible through a viewing portion having a VLT value greater than 5% and a second portion of the cartridge is configured to be hidden from view through the viewing portion.

12. The cartridge of claim 9 , wherein a label is affixed to at least one of the front wall and the rear wall, the label being configured to be hidden from view when the cartridge is inserted into the dispenser.

13. The cartridge of claim 9 , wherein the cartridge is configured to be received by the dispenser in an inverted orientation.

14. The cartridge of claim 9 , wherein the cartridge is configured to contain a fluid within the inner volume and the fluid is configured to be visible when the cartridge is inserted into the dispenser.
