Abstract
A child resistant dispenser that is child resistant without assistance from secondary child resistant packaging. The child resistant dispenser includes a locking mechanism disposed between a cap and a housing and the cap is frangibly coupled to the housing. The child resistant dispenser may be formed of a single material that is suitable for a blow-fill-seal process.
Claims20
A disposable dispenser comprising:
- a housing including:
- a reservoir for containing a product to be dispensed;
- and
- an outlet disposed on the reservoir for dispensing the product from the reservoir;
- a cap frangibly coupled to the housing and sealing the outlet of the reservoir to prevent the product from escaping the reservoir prior to use;
- and
- a locking mechanism disposed between the cap and the housing, the locking mechanism preventing the cap from being removed until the locking mechanism is released, wherein the locking mechanism is configured to be released by a first operation comprising a predetermined lateral force asserted on the locking mechanism towards a center of the housing, and the cap is configured to be removed from the housing by a second operation that is different than the first operation, the locking mechanism preventing the second operation until after performance of the first operation.

A unit-dose dispenser comprising:
- a housing including:
- a reservoir containing a single dose of a product to be dispensed;
- and
- an outlet disposed on the reservoir for dispensing the product from the reservoir;
- a cap frangibly coupled to the housing and sealing the outlet of the reservoir to prevent the product from escaping the reservoir prior to use;
- and
- a locking mechanism comprising a pair of tabs attached to an outer surface of the housing and on opposite sides of the housing, the pair of tabs extending between the cap and the housing, the locking mechanism preventing the cap from being rotated while the tabs are intact, each tab having a failure zone that is weaker relative to the remainder of the tab, such that each tab is configured to break at the failure zone upon application of a predetermined force wherein the locking mechanism is configured to be released by a first operation comprising a predetermined lateral force asserted on the locking mechanism towards a center of the housing, and the cap is configured to be removed from the housing by a second operation that is different than the first operation, the locking mechanism preventing the second operation until after performance of the first operation.

A disposable, unit-dose dispenser comprising:
- a housing including:
- a reservoir for containing a product to be dispensed;
- and
- an outlet disposed on the reservoir for dispensing the product from the reservoir;
- a cap coupled to the housing and sealing the outlet of the reservoir to prevent the product from escaping the reservoir prior to use;
- and
- a locking mechanism preventing the cap from being removed until the locking mechanism is released, the locking mechanism comprising a pair of tabs frangibly attached to the housing and extending in a substantially parallel manner away from the housing wherein the locking mechanism is configured to be released by a first operation comprising a predetermined lateral force asserted on the locking mechanism towards a center of the housing, and the cap is configured to be removed from the housing by a second operation that is different than the first operation, the locking mechanism preventing the second operation until after performance of the first operation.
