Abstract

A dispenser for dispensing fluid material from a replaceable container received within the dispenser. The dispenser includes a cover attached to a base mounting plate for movement longitudinally and pivotally with respect thereto and into and out of covering relationship therewith and a latch carried by the base mounting plate and movable into and out of locking engagement with the cover in response to actuation of a lever easily accessible in the closed condition. The cover has a large sight window occupying a substantial portion of its surface and enabling a substantial portion of one face of the container to be viewed when the cover is closed. Material is dispensed by actuating a pressure bar and an adjustable stop is provided to selectively vary the range of movement of the pressure bar and the amount of material dispensed.

Claims

1. A dispenser of the type wherein material is dispensed through a collapsible dispensing member by engaging the dispensing member with a pressure member, comprising:

a) an adjustable control member disposed between the pressure member and a portion of the dispenser to control the range of movement of the pressure member relatively of the collapsible dispensing member during the dispensing operation;

b) said control member is carried by the pressure member; and

c) the pressure member including an elongate unitary body pivotally mounted on the dispenser in engagement with the collapsible dispensing member, whereby the pressure member activates the collapsible dispensing member to dispense material upon the application of pressure thereto and returns the collapsible dispensing member to its starting position upon release of pressure on the pressure member.

2. The dispenser of claim 1 wherein said control member is carried on one end of the pressure member and adjustable from beneath the pressure member to selectively vary the range of movement of the pressure member relatively of the collapsible dispensing member during the dispensing operation.

3. The dispenser of claim 2 wherein said control member includes a rotatable stop having projections of varying heights for selective engagement with said portion of the dispenser.

4. A dispenser for dispensing fluid material from a container releasably receivable within the dispenser, comprising:

a) a base mounting plate including means for supporting the container;

b) a cover attached to said base mounting plate for movement longitudinally and pivotally with respect thereto into and out of covering relationship therewith;

c) latch means carried by said cover and said base mounting plate for releasably retaining said cover in covering relationship with said base mounting plate;

d) an elongate pressure member pivotally secured to the dispenser for movement toward and away from said base mounting plate to dispense material from said container; and

e) means for selectively adjusting the range of movement of said pressure member, said means including an adjustable control member carried by one end of said pressure member for engagement with said means for supporting the container and being adjustable from beneath said pressure member.

5. The dispenser of claim 4 wherein said latch means include a latch hingedly carried by said base mounting plate and movable into and out of locking engagement with said cover.

6. The dispenser of claim 5 wherein said latch means includes a lever accessible from beneath said cover for moving said latch out of locking engagement with said cover.

7. The dispenser of claim 4 wherein said means for selectively adjusting the range of movement of said pressure member includes a control member carried by said pressure member and movable into engagement with said means for supporting the container when said pressure member is moved toward said base mounting plate.

8. The dispenser of claim 7 wherein said control member is adjustable from beneath said cover to vary the distance traveled by said pressure member before engagement between said control member and said portion of said base mounting plate.

9. The dispenser of claim 8 wherein said control member includes means to permit it to be releasably lockable in selected adjusted positions.

10. The dispenser of claim 4 wherein said cover includes a transparent window occupying a substantial area thereof whereby a substantial portion of the container may be observed when said cover is in covering relationship with said base mounting plate.
