Abstract
A package has a sleeve and an insert that lock together. The insert has a longitudinal flange on one side that fits into a corresponding longitudinal channel in the sleeve. The sleeve includes a locking tab in line with the longitudinal channel that is foldable into the sleeve to present a deflectable contact edge across the longitudinal channel. Engagement of the locking tab contact edge with a shoulder on the longitudinal flange prevents movement of the insert in the direction of the locking tab. The insert can be locked in both a forward and a backward direction within the sleeve by providing respective locking tabs and shoulders at both ends of the package.
Claims28
A package, comprising:
- an insert;
- an insert flange extending along a side of the insert, the insert flange including a shoulder;
- a sleeve having an open end, wherein the sleeve fits closely around the insert and includes a longitudinal channel providing a longitudinal path along the length of the sleeve for receiving the insert flange;
- and
- a locking tab extending from the sleeve in line with the longitudinal channel, wherein the locking tab is foldable into the sleeve to present a contact edge extending across the longitudinal path,
- such that the insert is loadable into the sleeve to a position in which the insert flange shoulder is engageable with the contact edge of the locking tab, so as to prevent movement of the insert in the direction of the locking tab.
A packaging sleeve, comprising:
- at least one sheet of a creasable, resiliently deformable material that is formed into a sleeve body having at least one open end, wherein the sleeve fits closely around a packaging insert and includes a longitudinal channel along its length that provides a longitudinal path for a longitudinal flange extending along the length of the packaging insert,
- wherein the formed sleeve further includes a locking tab extending from the sleeve in line with the longitudinal channel, wherein the locking tab is foldable into the sleeve into a configuration in which it presents a deflectable contact edge extending across the longitudinal path.
A packaging blank, comprising:
- at least one sheet of a creasable, resiliently deformable material having defined sections therein such that the sheet is formable into a packaging sleeve,
- wherein the sheet is formable into a sleeve having an open end, wherein the sleeve fits closely around a packaging insert and includes a longitudinal channel along its length providing a longitudinal path for a longitudinal flange extending along the length of the packaging insert,
- wherein the formed sleeve further includes a locking tab extending therefrom in line with the longitudinal channel, wherein the locking tab is foldable into the sleeve into a configuration in which it presents a deflectable contact edge extending across the longitudinal path.
A packaging insert, comprising:
- an insert body that is shaped to fit closely within an outer sleeve,
- an insert flange extending along a side of the insert body, wherein the insert flange includes a shoulder,
- wherein the insert flange is shaped to travel along a longitudinal path defined by a longitudinal channel extending along the length of the packaging sleeve,
- wherein engagement of the shoulder by a contact edge of a locking tab folded into the sleeve interior across the longitudinal path prevents movement of the insert in the direction of engagement.
