Dispensing pump lock
First Claim
1. A locking assembly for use with a pump-type dispenser, to dispense material from a container, comprising:
- an actuator including an integral obstruction;
a support ring slidably engaged with the actuator; and
a locking mechanism integral to the support ring for limiting movement of the actuator until the obstruction is properly aligned with the locking mechanism, wherein alignment is achieved by rotating the actuator to a first predetermined position, partially depressing the actuator, then rotating the actuator to a second predetermined position where the actuator may be fully depressed for dispensing.

Abstract
Disclosed is a locking assembly for use with a pump-type dispenser to dispense material from a container. The assembly includes an actuator including at least one tooth integral to the actuator and a support ring which slidably engages the actuator. The support ring has at least one integral circumferential ridge with at least one ridge slot. The ridge is for limiting movement of the actuator until the tooth is properly aligned with the ridge slot, thereby allowing movement of the actuator and dispensing of product from the container. Alignment of the ridge slot and tooth may be achieved by rotating the actuator until an actuator position indicator on the actuator is aligned with an unlocking indicator on the support ring.

8. A locking assembly for use with a pump-type dispenser, to dispense material from a container, comprising:
-
an actuator including an integral obstruction; a support ring slidably engaged with the actuator; and a locking mechanism integral to the support ring for limiting movement of the actuator until the obstruction is properly aligned with the locking mechanism, wherein alignment is achieved by rotating the actuator to a first predetermined position, wherein the integral obstruction is at least one tooth, wherein the locking mechanism includes at least one circumferential ridge extending at least partially around the support ring, wherein the at least one circumferential ridge includes a ridge slot at a predetermined position along the circumferential ridge, wherein the actuator includes an actuator position indicator, and the support ring includes an unlocking indicator, alignment of the position indicator with the unlocking indicator indicating when the tooth is properly aligned with the ridge slot for disengagement of the locking assembly, wherein the tooth and ridge are each configured so that the tooth slides over the ridge in a first direction, and the ridge obstructs movement of the tooth in a second direction, wherein the locking mechanism includes a first circumferential ridge having a first ridge slot, and a second circumferential ridge having a second ridge slot, the first ridge slot being positioned at a different circumferential position on the first ridge than the circumferential position of the second ridge slot on the second ridge.

9. A pump dispenser including a locking assembly, comprising:
-
an actuator for drawing materials from a container to dispense the materials from the container, the actuator including an integral obstruction; a support ring slidably engaged with the actuator for relative reciprocating movement in an axial direction; and a locking mechanism integral to the support ring for limiting axial movement of the actuator until the obstruction is properly aligned with the locking mechanism, wherein alignment is achieved by rotating the actuator to a first predetermined position, wherein the obstruction and locking mechanism are each configured so that the obstruction slides over the locking mechanism in a first axial direction and, the locking mechanism obstructs movement of the obstruction in a second axial direction thereby preventing axial movement of the actuator to dispense materials from the container. - View Dependent Claims (10, 11, 12, 13, 14)

15. A pump dispenser including a locking assembly, comprising:
-
an actuator for drawing materials from a container to dispense the materials from the container, the actuator including an integral obstruction; a support ring slidably engaged with the actuator; and a locking mechanism integral to the support ring for limiting movement of the actuator until the obstruction is properly aligned with the locking mechanism, wherein alignment is achieved by rotating the actuator to a first predetermined position, wherein the obstruction and locking mechanism are each configured so that the obstruction slides over the locking mechanism in a first direction and, the locking mechanism obstructs movement of the obstruction in a second direction thereby preventing movement of the actuator to dispense materials from the container, wherein the integral obstruction is at least one tooth, wherein the locking mechanism includes at least one circumferential ridge extending at least partially around the support ring, wherein the at least one circumferential ridge includes a ridge slot at a predetermined position along the circumferential ridge, wherein the actuator includes an actuator position indicator, and the support ring includes an unlocking indicator, alignment of the position indicator with the unlocking indicator indicating when the tooth is properly aligned with the ridge slot for disengagement of the locking assembly, wherein the locking mechanism includes a first circumferential ridge having a first ridge slot, and a second circumferential ridge having a second ridge slot, the first ridge slot being positioned at a different circumferential position on the first ridge than the circumferential position of the second ridge slot on the second ridge.

16. A container, comprising:
-
a body for storing materials therein, the body having a pump dispenser secured thereto; the pump dispenser includes; an actuator including at least one integral tooth; a support ring slidably engaged with the actuator for relative reciprocating movement in an axial direction; and at least one circumferential ridge extending at least partially around the support ring and being integral to the support ring for limiting axial movement of the actuator until the tooth is properly aligned with the ridge, wherein alignment is achieved by rotating the actuator to a first predetermined position, wherein the tooth and ridge are each configured so that the tooth slides over the ridge in a first axial direction and, the ridge obstructs movement of the tooth in a second axial direction thereby preventing axial movement of the actuator to dispense materials from the container. - View Dependent Claims (17, 18)

19. A container, comprising:
-
a body for storing materials therein, the body having a pump dispenser secured thereto; the pump dispenser includes; an actuator including at least one integral tooth; a support ring slidably engaged with the actuator; and at least one circumferential ridge extending at least partially around the support ring and being integral to the support ring for limiting movement of the actuator until the tooth is properly aligned with the ridge, wherein alignment is achieved by rotating the actuator to a first predetermined position, wherein the tooth and ridge are each configured so that the tooth slides over the ridge in a first direction and, the ridge obstructs movement of the tooth in a second direction thereby preventing movement of the actuator to dispense materials from the container, wherein the at least one circumferential ridge includes a ridge slot at a predetermined position along the circumferential ridge, further comprising an upper circumferential ridge and a lower circumferential ridge, each ridge having a ridge slot, the ridge slots being at different circumferential position on the support ring such that rotating the actuator to the first predetermined position allows the tooth to pass through the upper ridge slot and come into contact with the lower ridge, and subsequently rotating the actuator to a second predetermined position allows the tooth to pass through the lower ridge slot to allow dispensing of materials from the container, there being at least one by-pass member connecting the upper and lower ridges and configured such that when the tooth is in contact with the lower ridge and the actuator is turned in a direction away from the second predetermined position, the tooth rides up the by-pass member and returns to a position in which the upper ridge obstructs movement of the tooth, thereby preventing movement of the actuator to dispense materials from the container. - View Dependent Claims (20, 21)
