Abstract
This invention relates to a secondary locking system for wrap-around carriers. A secondary male lock is held in the vertical position by a female flap leaning against the male lock. The adjacent pairs of secondary male locks and corresponding female locks are aligned with each other along a single longitudinal line which traverses an adjacent article contained within the carrier.
Claims21
A wrap-around article carrier for carrying articles comprising:
- a) a top panel, opposite side panels and a bottom panel;
- b) the bottom panel having inner and outer panel flaps, a portion of the outer panel flap overlapping a portion of the inner panel flap;
- c) the outer panel flap having at least one secondary male lock formed as an extension of the outer panel flap;
- d) the inner panel flap having at least one secondary female opening for each secondary male lock, said opening formed by a slit and interconnecting fold line which forms a female flap in the female opening, said female flap leaning against the secondary male lock when it has been extended through the female opening to assist in holding the secondary male lock in the vertical position in respect to the outer panel flap so the lock does not accidentally become disengaged;
- and
- e) said carrier having a longitudinal dimension running from one bottom panel flap to the opposite bottom panel flap with each secondary male lock and corresponding secondary female opening being aligned along a line traversing the longitudinal dimension of the carrier through the location of at least one article contained therein.

A bottom panel in an article carrier, said bottom panel being connected to the opposite side walls of the carrier, comprising:
- a) inner and outer bottom panel flaps, which are connected to the side walls of the carrier with a portion of the outer bottom panel flap overlapping a portion of the inner bottom panel flap;
- b) the outer bottom panel flap having at least one secondary male lock formed as an extension of the flap;
- c) the inner bottom panel flap having at least one secondary female opening for each secondary male lock, said opening formed by slit and interconnecting fold line which forms a female flap in the female opening, said female flap leaning against the secondary male lock when it has been extended through the female opening to assist in holding the secondary male lock in the vertical position in respect to the outer flap so the lock does not accidentally become disengaged;
- and
- d) said bottom panel having a longitudinal dimension running from one side wall to the opposite side wall with the secondary male lock and corresponding secondary female opening being aligned along a line traversing the longitudinal dimension of the bottom panel through the center of the location of at least one article located therein.

A blank for forming a wrap-around carrier comprising a generally rectangular sheet, said sheet comprising:
- a) at one end of the sheet an inner bottom panel flap having at least one secondary female opening for each secondary male lock, said opening formed by a slit and fold line which forms a female flap in the female opening;
- b) a side panel, a top panel, and an opposite side panel foldably connected to the inner bottom panel flap in that order;
- c) an outer bottom panel flap foldably connected to the opposite side panel, said outer bottom panel flap having at least one secondary male lock formed as an extension of the outer panel flap;
- and
- d) said blank having a longitudinal dimension running from the outer bottom panel flap to the inner bottom panel flap with each secondary male lock and corresponding secondary female opening being aligned along a line traversing the longitudinal dimension of the blank.
2 more elements
A wrap-around article carrier loaded with a plurality of articles with flexible walls comprising:
- a) a top panel, opposite side panels and a bottom panel;
- b) the bottom panel having inner and outer panel flaps, a portion of the outer panel flap overlapping a portion of the inner panel flap;
- c) the outer panel flap having at least one secondary male lock formed as an extension of the outer panel flap;
- d) the inner panel flap having at least one secondary female opening for each secondary male lock, said opening formed by a slit and interconnecting fold line which forms a female flap in the female opening, said female flap leaning against the secondary male lock when it has been extended through the female opening to assist in holding the secondary male lock in the vertical position in respect to the outer panel flap so the lock does not become accidentally disengaged;
- e) said carrier having a longitudinal dimension running from one bottom panel flap to the opposite bottom panel flap with each secondary male lock and corresponding secondary female opening being aligned along a line traversing the longitudinal dimension of the carrier through the location of at least one article contained therein;
- and
- f) the secondary male locks in corresponding secondary female locks being held in the locked position by pressure from the flexible sides of the articles contained therein.
