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.

1. 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; anda 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,wherein the locking tab includes a base defined by a horizontal crease, wherein the horizontal crease results in a selected height, relative to the sleeve interior, for the contact edge of the folded-in locking tab. 2. The package of claim 1, wherein the horizontal crease is angled. 3. The package of claim 1, wherein the horizontal crease is curved. 4. 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; anda 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,wherein the sleeve includes a first locking tab at a first end, and a second locking tab at a second end, andwherein the insert flange includes a first shoulder that is engageable by the contact edge of the first locking tab, and a second shoulder that is engageable by the second locking tab,such that engagement between the first shoulder and the contact edge of the first locking tab prevents movement in the direction of the first locking tab, andsuch that engagement between the second shoulder and the contact edge of the second locking tab prevents movement in the direction of the second locking tab,thereby securing the insert within the sleeve. 5. The package of claim 4, wherein the first shoulder and second shoulder are spaced sufficiently close together to allow the insert to be slid partway out of an end of the sleeve before engagement at that end between a shoulder and a contact edge of a locking tab. 6. 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;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; anddeactivation means for deactivating the locking tab, thereby allowing movement in the direction of the deactivated locking tab. 7. The package of claim 6, wherein the deactivation means comprises a breakaway section defined by a perforation around the locking tab, wherein removal of the breakaway section removes the locking tab from the package. 8. 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,wherein the locking tab has a horizontal crease at its base that is configured to create a selected height, relative to the sleeve interior, for the contact edge of the locking tab. 9. The packaging sleeve of claim 8, wherein the horizontal crease is angled. 10. The packaging sleeve of claim 8, wherein the horizontal crease is curved. 11. 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,wherein the locking tab comprises a longitudinal crease therein that is aligned with the longitudinal sleeve crease, andwherein the locking tab has a horizontal crease at its base that is configured to create a selected height, relative to the sleeve interior, for the contact edge of the locking tab. 12. The package of claim 11, wherein the horizontal crease is angled. 13. The package of claim 11, wherein the horizontal crease is curved.
