Child resistant dial trap pack
A child resistant container comprising a blister and a sleeve. The blister comprises a plurality of compartments arranged radially around a centrally disposed hub. Each compartment defines a cavity for holding contents. The container is a “dial pack” type container in that the blister can be rotated with respect to the sleeve to expose each cavity in turn.
1. A container comprising:
a sleeve comprising a front card and a substantially co-extensive back card connected by an integrally formed hinge;
the back card including score lines that define a flap, the flap being moveable to expose a dispensing window through which a compartment may be accessed;
the front card defining a locking boss opening and a large opening configured to receive a plurality of compartments; and
a blister rotatably sandwiched between the back card and the front card, the blister comprising a generally planar, circular body and the plurality of compartments, the plurality of compartments extending from the body and arranged radially around a centrally disposed hub, the hub defining a central rotational axis (A), each compartment defining a cavity for holding contents, each compartment comprising a bottom wall and a sidewall extending from the bottom wall and terminating in a top edge co-planar with the body;
the body defining a plurality of notches disposed around a periphery of the body, each notch located radially outward from a corresponding compartment;
the blister further comprising a member extending radially outward from the body and connected to the body by a removeable tab, the member comprising a downwardly extending locking boss; wherein
the container is configurable between a first, locked position in which the locking boss extends through the locking boss opening and nests within one of the plurality of notches so that the blister cannot rotate with respect to the front card and back card, and an unlocked position in which the locking boss does not extend through the opening and the blister is rotatable with respect to the front card and back card about the central axis (A).
2. The container of claim 1 wherein:
each compartment is sealed with a frangible seal.
3. The container of claim 2 wherein:
the frangible seal is adhered to the body in such a manner that breaking the seal over one compartment does not break the seal over other compartments.
4. The container of claim 1 wherein:
the flap is hingedly connected to the rest of back card and configured to expose the tab and the dispensing window when the flap is lifted or removed from the rest of the back card.
5. The container of claim 1 wherein:
the back card and the flap define a finger opening 46 to make it easier for a user to lift or remove the flap.
6. The container of claim 1 wherein:
the front card and back card are made from a single piece of material.
7. The container of claim 1 wherein:
the front card and the back card are configured to enclose a portion of the body while allowing the blister to rotate.
8. The container of claim 1 wherein:
the front card and the back card define an opening to accommodate a display hook.
9. The container of claim 1 wherein:
the bottom wall of each compartment is inclined in whole or in part to make it easier to remove the contents from the compartment.
10. A dial trap container comprising:
a sleeve comprising a front card and a substantially co-extensive back card, the back card including score lines that define a flap, the flap being moveable to expose a dispensing window through which a compartment may be accessed, the front card defining a locking boss opening and a large opening configured to receive a plurality of compartments; and
a blister rotatably sandwiched between the back card and the front card, the blister comprising a generally planar, circular body and the plurality of compartments, the plurality of compartments extending from the body and arranged radially around a central rotational axis (A), each compartment defining a cavity for holding contents, the body defining a plurality of notches disposed around a periphery of the body, the blister further comprising a locking boss extending downwardly through the locking boss opening; wherein
the container is configurable between a first, locked position in which the locking boss extends through the locking boss opening and nests within one of the plurality of notches so that the blister cannot rotate with respect to the front card and back card, and an unlocked position in which the locking boss does not extend through the opening and the blister is rotatable with respect to the front card and back card about the central axis (A).
11. The container of claim 10 wherein:
each compartment is sealed with a frangible seal.
12. The container of claim 11 wherein:
the frangible seal is adhered to the body in such a manner that breaking the seal over one compartment does not break the seal over other compartments.
13. The dial trap container of claim 10 wherein:
each compartment comprises a bottom wall and a sidewall extending from the bottom wall and terminating in a top edge co-planar with the body, and the bottom wall of each compartment is inclined in whole or in part to make it easier to remove the contents from the compartment.
14. The dial trap container of claim 10 wherein:
each notch is located radially outward from a corresponding compartment.
15. The dial trap container of claim 10 wherein the blister further comprises:
a member extending radially outward from the body and connected to the body by a removeable tab, wherein the locking boss extends downward from the member.
16. A method of dispensing contents from a container, the method comprising the steps of:
providing a container comprising a sleeve comprising a front card and a substantially co-extensive back card, the back card including score lines that define a flap, the front card defining a locking boss opening and a large opening configured to receive a plurality of compartments; and a blister rotatably sandwiched between the back card and the front card, the blister comprising a generally planar, circular body and the plurality of compartments, the plurality of compartments extending from the body and arranged radially around a central rotational axis (A), each compartment defining a cavity for holding contents, the body defining a plurality of notches disposed around a periphery of the body, the blister further comprising a locking boss connected to the blister body and extending downwardly through the locking boss opening;
pulling up on the flap to reveal a dispensing window and the tab;
removing the tab so the locking boss is no longer connected to the blister body;
depressing the locking boss to allow the blister to rotate with respect to the front card and back card;
rotating the blister until a compartment is aligned with the dispensing window; and
accessing the contents of the compartment cavity.
17. The method of claim 16 , wherein each compartment is sealed with a frangible seal, the method comprising the additional step of:
pushing on a bottom of the compartment to force the contents through the frangible seal.
18. The method of claim 16 , wherein the body defines a plurality of notches disposed around a periphery of the body, wherein:
the rotating step includes rotating the blister until the next notch registers with and partially captured by the stationary locking boss.
19. The method of claim 18 , wherein:
during the rotating step, the blister slides smoothly over the locking boss, keeping the locking boss depressed until the next notch registers with the locking boss.
20. The method of claim 19 , wherein:
after the rotating step, the locking boss pops up through the small button opening in the front card and nests within the next peripheral notch so the blister cannot rotate.
