Collapsible receptacle

A collapsible receptacle reconfigurable between an expanded configuration for retaining a volume of material and a collapsed configuration, the collapsible receptacle comprising:

• an inner sleeve with first and second opposed major walls divided by opposed fold lines;
• an outer sleeve engaged with the inner sleeve wherein the outer sleeve has first and second opposed major walls divided by opposed fold lines;
• and
• a liner retained by the inner and outer sleeves;
• wherein the receptacle can be retained in the expanded configuration with an open inner volume defined by the liner when the opposed fold lines of the inner sleeve are not aligned with the opposed fold lines of the outer sleeve and wherein the receptacle can be reconfigured to the collapsed configuration when the opposed fold lines of the inner sleeve and the outer sleeve are aligned and wherein the first and second major walls of at least the inner sleeve or the outer sleeve taper in thickness from mid-portions of the first and second major walls toward the opposed fold lines.

A collapsible receptacle reconfigurable between an expanded configuration for retaining a volume of material and a collapsed configuration, the collapsible receptacle comprising:

• an inner sleeve with first and second opposed major walls divided by opposed fold lines;
• an outer sleeve engaged with the inner sleeve wherein the outer sleeve has first and second opposed major walls divided by opposed fold lines;
• and
• a liner retained by the inner and outer sleeves;
• wherein the receptacle can be retained in the expanded configuration with an open inner volume defined by the liner when the opposed fold lines of the inner sleeve are not aligned with the opposed fold lines of the outer sleeve and wherein the receptacle can be reconfigured to the collapsed configuration when the opposed fold lines of the inner sleeve and the outer sleeve are aligned;
• wherein the inner and outer sleeves are generally cylindrical with open upper and lower ends when the receptacle is in the expanded configuration and wherein the opposed fold lines of the inner and outer sleeves are substantially longitudinal.

A collapsible receptacle reconfigurable between an expanded configuration for retaining a volume of material and a collapsed configuration, the collapsible receptacle comprising:

• an inner sleeve with first and second opposed major walls divided by opposed fold lines;
• an outer sleeve engaged with the inner sleeve wherein the outer sleeve has first and second opposed major walls divided by opposed fold lines;
• a liner retained by the inner and outer sleeves;
• wherein the receptacle can be retained in the expanded configuration with an open inner volume defined by the liner when the opposed fold lines of the inner sleeve are not aligned with the opposed fold lines of the outer sleeve and wherein the receptacle can be reconfigured to the collapsed configuration when the opposed fold lines of the inner sleeve and the outer sleeve are aligned;
• a lid structure removably and replaceably engageable with the liner to enclose the open inner volume;
• and
• a retaining ring disposed on the liner for engaging and retaining the lid structure.

A collapsible receptacle reconfigurable between an expanded configuration for retaining a volume of material and a collapsed configuration, the collapsible receptacle comprising:

• an inner sleeve with first and second opposed major walls divided by opposed fold lines;
• an outer sleeve rotatably engaged with the inner sleeve wherein the outer sleeve has first and second opposed major walls divided by opposed fold lines;
• a liner retained by the inner and outer sleeves;
• and
• a rotation limiting formation on the inner sleeve and a rotation limiting formation on the outer sleeve wherein the rotation limiting formations prevent over-rotation of the inner sleeve relative to the outer sleeve;
• wherein the receptacle can be retained in the expanded configuration with an open inner volume defined by the liner when the opposed fold lines of the inner sleeve are not aligned with the opposed fold lines of the outer sleeve and wherein the receptacle can be reconfigured to the collapsed configuration when the opposed fold lines of the inner sleeve and the outer sleeve are aligned.

A collapsible beverage cup that is reconfigurable between an expanded configuration for retaining a volume of material and a collapsed configuration, the collapsible beverage cup comprising:

• an inner sleeve with first and second opposed major walls divided by opposed, longitudinal fold lines;
• an outer sleeve engaged with the inner sleeve wherein the outer sleeve has first and second opposed major walls divided by opposed, longitudinal fold lines wherein the opposed fold lines of the outer sleeve are disposed in groups with at least two fold lines to a first side of the outer sleeve and at least two fold lines to a second side of the outer sleeve opposite the first side whereby the outer sleeve has opposed minor walls;
• and
• a liquid-tight liner retained by the inner and outer sleeves;
• wherein the beverage cup can be retained in the expanded configuration with an open inner volume defined by the liner when the opposed fold lines of the inner sleeve are not aligned with the opposed fold lines of the outer sleeve and wherein the beverage cup can be reconfigured to the collapsed configuration when the opposed fold lines of the inner sleeve and the outer sleeve are aligned.
