Abstract

A fluid dispenser having a housing with a cover coupled to the housing for movement between a closed position and an open position and a lifting member coupled to the housing between the housing and the cover whereby movement of the lifting member as guided by the housing moves the cover between the open position and the closed position.

First claim

We claim:

1. A fluid dispenser having:
a housing having an interior with a forward opening providing access to the interior of the housing,
a removable member selected from the group consisting of a fluid reservoir and a pump mechanism,
a cover coupled to the housing for movement upwardly and downwardly between a closed position of the cover in which the dispenser is operative for dispensing fluid and an open position of the cover,
a cover actuator member coupled to the housing for guided movement between a closed position of the cover actuator member and an open position of the cover actuator member guided by the housing including pivoting of the cover actuator member about at least one horizontal pivot axis relative the housing,
the cover actuator member in the guided movement relative the housing engaging the cover to move the cover to between the open position of the cover and the closed position of the cover relative the housing such that with the cover actuator member in the closed position of the cover actuator member, the cover is in the closed position of the cover and with the cover actuator member in the open position of the cover actuator member, the cover is in the open position of the cover,
with the cover actuator member in the closed position of the cover actuator member and the cover in the closed position of the cover, the cover covers a first portion of the forward opening of the housing and insertion and removal of the removable member from within the interior of the housing through the forward opening is prevented.

2. A fluid dispenser as claimed in claim 1 wherein the forward opening includes the first portion and a second portion,
with the cover actuator member in the closed position of the cover actuator member and the cover in the closed position of the cover, the cover covers the first portion of the forward opening of the housing preventing insertion and removal of the removable member from within the interior of the housing through the forward opening.

3. A fluid dispenser as claimed in claim 1 wherein the forward opening includes the first portion and a second portion,
with the cover actuator member in the closed position of the cover actuator member and the cover in the closed position of the cover, the cover actuator member covers the second portion of the forward opening of the housing preventing insertion and removal of the removable member from within the interior of the housing through the forward opening.

4. A fluid dispenser as claimed in claim 1 wherein the forward opening includes the first portion and a second portion,
with the cover actuator member in the closed position of the cover actuator member and the cover in the closed position of the cover, the cover covers the first portion of the forward opening of the housing and the cover actuator member covers the second portion of the forward opening of the housing together preventing insertion and removal of the removable member from within the interior of the housing through the forward opening.

5. A fluid dispenser as claimed in claim 4 wherein with the cover actuator member in the open position of the cover actuator member and the cover in the open position of the cover, the first portion of the forward opening of the housing and the second portion of the access opening are open permitting insertion and removal of the removable member from within the interior of the housing through the forward opening.

6. A fluid dispenser as claimed in claim 5 wherein in the cover moving from the closed position of the cover to the open position of the cover, the cover moves vertically away from the cover actuator member to uncover the first portion and, in the cover actuator member moving from the closed position of the cover actuator member to the open position of the cover actuator member, the cover actuator member moves vertically away from the cover to uncover the second portion.

7. A dispenser as claimed in claim 6 wherein when the cover actuator member is in the closed position of the cover actuator member covering the first portion of the forward opening of the housing and the cover is in the closed lower position of the cover covering the second portion of the forward opening of the housing, a viewing opening is provided into the interior of the housing between the cover actuator member and the cover intermediate the lower portion of the forward opening of the housing and the upper portion of the forward opening of the housing.

8. A fluid dispenser as claimed in claim 1 wherein the guided movement includes guided sliding of the lifting member forwardly and rearwardly relative the housing.

9. A fluid dispenser as claimed in claim 8 wherein the housing includes a pair of spaced side walls,
the cover actuator member including a pair of spaced arms, with one arm adjacent each of the side walls of the housing,
a stub axle member carried by each arm extending horizontally into an opening in an adjacent side wall,
the opening selected from a circular opening within which the stub axle is rotatable about a first horizontal axis, and a front to rear extending slotway in which the axle member is slidable between forward and rear positions with the stub axle rotatable within the slotway at each of a plurality of different positions within the slotway about a respective horizontal axis at each of the positions.

10. A fluid dispenser as claimed in claim 9 wherein the cover having a right cover side wall and a left cover side wall secured together spaced laterally from each other, and a top wall bridging between an upper portion of the right cover side wall and an upper portion of left cover side wall.

11. A fluid dispenser as claimed in claim 6 wherein the guided movement includes guided sliding of the cover actuator member forwardly and rearwardly relative the housing, within movement from the closed position to the open position, a front portion of the cover actuator member moving vertically and rearwardly relative to the housing and a rear portion of the cover actuator member in engagement with the cover moving vertically relative the housing.

12. A fluid dispenser as claimed in claim 1 wherein:
the closed position of the cover is upward from the open position of the cover,
the closed position of the cover actuator member is downward from the open position of the cover actuator member.

13. A fluid dispenser as claimed in claim 1 wherein:
the closed position of the cover is downward from the open position of the cover,
the closed position of the cover actuator member is upward from the open position of the cover actuator member.

14. A fluid dispenser as claimed in claim 13 wherein the removable member comprises the fluid reservoir, the fluid reservoir comprising a bottle supported on the housing within the interior of the housing with a bottom of the bottle within the interior rearward of the second portion and, when the cover actuator member is in the closed position of the cover actuator member, rearward of the cover actuator member.

15. A fluid dispenser as claimed in claim 13 wherein the removable member comprises the pump mechanism, the pump mechanism supported on the housing within the interior of the housing rearward of the first portion and, when the cover is in the closed position of the cover, rearward of the cover.

16. A fluid dispenser as claimed in claim 14 wherein the removable member comprises the pump mechanism, the pump mechanism supported on the housing within the interior of the housing rearward of the first portion and, when the cover is in the closed position of the cover, rear
