Lock-out device and method
View Patent ↗A method and device to insure that a particular dispensing package ( 18 ) can only be engaged into an appropriate dispensing location ( 14 ). Specifically, the package and the dispenser have mating concentric rings ( 24, 30 ) (or portions thereof) to prevent engagement and dispensing of an inappropriate product. In one embodiment, the package ( 18 ) is provided with one or more concentric ring projections ( 24 ) (or portions thereof) and the dispenser ( 10 ) is provided with one or more matching concentric ring recesses ( 30 ). The projections and the recesses have similar diameters to define a mating set. In some embodiments, the concentric ring projections are placed on a closure ( 20 ), such as a cap, of the package. In alternative embodiments, the projections are placed on the dispenser and the recesses are placed on the package.
1. A lock-out assembly for controlling engagement between a package and a dispensing apparatus having an upwardly oriented cradle, the lock-out assembly comprising:
a closure attachable to the package and including a downwardly-facing mating surface;
a selectively movable insert removably receivable in the cradle and having an upwardly-facing mating surface;
an annular recess positioned on one of the downwardly-facing mating surface of the closure and the upwardly-facing mating surface of the insert about at least a portion of a circumference of a circle having a first diameter; and
an annular projection positioned on the other of the downwardly-facing mating surface of the closure and the upwardly-facing mating surface of the insert about at least a portion of the circumference of a circle having the first diameter, the projection dimensioned and configured to releasably mate with the recess to engage the package with the dispensing apparatus.
2. The lock-out assembly of claim 1 , wherein the recess extends around the entire circumference of the circle having the first diameter.
3. The lock-out assembly of claim 1 , wherein the projection extends around only a portion of the circumference of the circle having the first diameter.
4. The lock-out assembly of claim 1 , wherein the projection and a rib releasably engage the recess.
5. The lock-out assembly of claim 1 , further comprising a second recess concentric with the first recess.
6. The lock-out assembly of claim 5 , further comprising a second projection concentric with the first projection and engageable with the second recess.
7. A dispensing apparatus comprising:
a package containing a product to be dispensed, the package including a closure defined by a downwardly-facing mating surface having a projection positioned about a circle having a diameter;
a dispensing location including an upwardly oriented cradle; and
a selectively movable insert removably received in the cradle, the insert having an upwardly-facing mating surface releasably mating with the downwardly-facing mating surface of the closure, the upwardly-facing mating surface having a recess positioned about a circle having the diameter, the projection cooperating with the recess to engage the package with the dispensing location such that the product can be dispensed from the first package.
8. The dispensing apparatus of claim 7 wherein the closure is selectively removable from the package.
9. The dispensing apparatus of claim 7 wherein the projection extends only partially around the circle having the diameter.
10. The dispensing apparatus of claim 7 wherein the recess extends around the entire circle having the diameter.
11. The dispensing apparatus of claim 7 further comprising:
a second package containing a second product to be dispensed, the second package including a second closure defined by a downwardly-facing mating surface having at least one projection positioned about a circle having a second diameter different than the diameter associated with the projection of the first closure; and
a second dispensing location including a second upwardly oriented cradle;
a second selectively movable insert removably received in the second cradle, the second insert having an upwardly-facing mating surface releasably mating with the downwardly-facing mating surface of the closure, the upwardly-facing mating surface having at least one recess positioned about a circle having the second diameter;
wherein the diameter of the projections and the recesses allow the second package to engage the second dispensing location such that the second product can be dispensed from the second package; and
wherein the diameter of the projections and the recesses prevent the first package from engaging the second dispensing location to dispense the first product and prevent the second package from engaging the first dispensing location to dispense the second product.
12. The dispensing apparatus of claim 7 , wherein the projection and a rib releasably engage the recess.
13. The dispensing apparatus of claim 7 further comprising a second projection positioned about a circle having a second diameter different than the diameter associated with the projection and the recess, and wherein the second projection extends only partially around the circle having the second diameter.
14. The dispensing apparatus of claim 13 further comprising a second recess positioned about a circle having the second diameter, wherein the second recess extends around the entire circle having the second diameter.
15. The dispensing apparatus of claim 14 wherein the first recess is positioned adjacent the second recess to form a single large recess.
16. The dispensing apparatus of claim 14 wherein the circle having the second diameter is concentric with the circle having the first diameter.
17. A dispensing apparatus comprising:
a package containing a product to be dispensed, the package including a closure defined by a downwardly-facing mating surface having a recess positioned about a circle having a diameter;
a dispensing location including an upwardly oriented cradle and a selectively movable insert removably received in the cradle, the insert having an upwardly-facing mating surface releasably mating with the downwardly-facing mating surface of the closure, the upwardly-facing mating surface having a projection positioned about a circle having the diameter; and
wherein the projection is matable with the recess to allow the package to engage the dispensing location such that the product can be dispensed from the package.
18. The dispensing apparatus of claim 17 wherein the projection extends only partially around the circle having the diameter.
19. The dispensing apparatus of claim 17 wherein the recess extends around the entire circle having the diameter.
20. The dispensing apparatus of claim 17 further comprising:
a second package containing a second product to be dispensed, the second package having at least one recess positioned about a circle having a second diameter different than the first diameter; and
a second dispensing location including a second selectively movable insert removably received in the cradle, the second insert having at least one projection positioned about a circle having the second diameter;
wherein the diameter of the projections and the recesses allow the second package to engage the second dispensing location such that the second product can be dispensed from the second package; and
wherein the diameter of the projections and the recesses prevent the first package from engaging the second dispensing location to dispense the first product and prevent the second package from engaging the first dispensing location to dispense the second product.
21. The dispensing apparatus of claim 17 , wherein the projection and a rib releasably engage the recess.
22. The dispensing apparatus of claim 17 wherein the package comprises a closure and wherein the recess is positioned on the closure.
23. The dispensing apparatus of claim 22 wherein the closure is selectively removable from the package.
24. The dispensing apparatus of claim 17 further comprising a second recess positioned about a circle having a second diameter different than the diameter of the first recess, and wherein the second recess extends around the entire circle having the second diameter.
25. The dispensing apparatus of claim 24 wherein the first recess is positioned adjacent the second recess to form a single large recess.
26. The dispensing apparatus of claim 24 further comprising a second projection positioned about a circle having the second diameter, and wherein the second projection extends only partially around the circle having the second diameter.
27. The dispensing apparatus of claim 26 wherein the circle having the second diameter is concentric with the circle having the first diameter.
