Abstract

A reservoir assembly for use with a liquid dispenser. The reservoir assembly includes a connecting member housing having a reservoir connecting surface and a switch, wherein the reservoir connecting surface has a first switch contact surface disposed within a first protrusion member. The assembly also includes a container housing that is configured to be removably attached to the connecting member housing. The container housing includes a main container and a connecting member housing surface that includes a second switch contact surface configured in a first weakened region. After contact of the first switch contact surface and the second switch contact surface, the protrusion member is configured to engage the first weakened region such that the first weakened region breaks away from the connecting member housing surface such that first switch contact surface and second switch contact surface are unable to make contact.

First claim

What is claimed is:

1 . A reservoir assembly for use with a liquid dispenser comprising:
a connecting member housing having a reservoir connecting surface and a switch, the reservoir connecting surface having a first switch contact surface disposed within a first protrusion member; and a container housing for holding a quantity of a liquid, the container housing configured to be removably attached to the connecting member housing, the container housing comprising a main container and a connecting member housing surface, the connecting member housing surface having a second switch contact surface configured in a first weakened region, wherein after contact of the first switch contact surface and the second switch contact surface, the protrusion member is configured to engage the first weakened region such that the first weakened region breaks away from the connecting member housing surface such that first switch contact surface and second switch contact surface are unable to make contact.

2 . The reservoir assembly of claim 1 , wherein upon contact of the first switch contact surface and the second switch contact surface, a dispense count is set to zero.

3 . The reservoir assembly of claim 1 , wherein the connecting member housing comprises control circuitry and/or one or more sensors operably configured to communicate a dispense count to a computing system.

4 . The reservoir assembly of claim 1 , wherein a portion of the first protrusion member engaging the first weakened region extends farther in a z-direction than the first switch contact surface.

5 . The reservoir assembly of claim 1 , wherein the second switch contact surface extends farther in a z-direction than a portion of the first weakened region engaging the first protrusion member.

6 . The reservoir assembly of claim 1 , wherein the first weakened region is configured such that the first weakened region is not completely dislodged from the connecting member housing surface.

7 . The reservoir assembly of claim 1 , wherein the first weakened region is configured such that the first weakened region is completely dislodged from the connecting member housing surface.

8 . The reservoir assembly of claim 1 , wherein the connecting member housing is secured either directly or indirectly to a dispensing head disposed above a counter.

9 . The reservoir assembly of claim 1 , wherein the connecting member housing comprises a pump device operative to pump the liquid through a fluid outlet defined in the connecting member housing surface.

10 . The reservoir assembly of claim 1 , wherein the reservoir connecting surface comprises a second protrusion member configured to contact a second weakened region having a third switch contact surface on the connecting member housing surface, wherein the second weakened region is configured to breakaway when contacted by the second protrusion member.

11 . A counter-mounted liquid product dispensing apparatus comprising:
a fixture assembly mounted to a counter comprising: a dispensing head mounted to the counter, the dispensing head having one or more delivery spouts configured to dispense liquid product to a user; a reservoir assembly comprising: a connecting member housing secured either directly or indirectly to the dispenser head, the connecting member housing having a reservoir connecting surface and a switch, the reservoir connecting surface including a first switch contact surface disposed within a first protrusion member; a container housing configured to be removably attached to the connecting member, the container housing comprising a main container for holding a quantity of a liquid product and a connecting member housing surface, the connecting member housing surface having a second switch contact surface configured in a first weakened region, wherein upon contact of the first switch contact surface and the second switch contact surface, the protrusion member is configured to engage the first weakened region such that the first weakened region breaks away from the connecting member housing surface such that first switch contact surface and second switch contact surface are unable to make contact; and a pump device coupled to the connecting member housing, the pump device operative to pump the liquid product through a fluid outlet defined in the connecting member housing surface.

12 . The apparatus of claim 11 , wherein the connecting member housing comprises control circuitry and/or one or more sensors operably configured to communicate a dispense count to a computing system.

13 . The apparatus of claim 11 , wherein upon contact of the first switch contact surface and the second switch contact surface, a dispense count is set to zero.

14 . The apparatus of claim 11 , wherein a portion of the first protrusion member engaging the first weakened region extends farther in a z-direction than the first switch contact surface.

15 . The apparatus of claim 11 , wherein the second switch contact surface extends farther in a z-direction than a portion of the first weakened region engaging the protrusion member.

16 . The apparatus of claim 11 , wherein the first weakened region is configured such that the first weakened region is not completely dislodged from the connecting member housing surface.

17 . The apparatus of claim 11 , wherein the first weakened region is configured such that the first weakened region is completely dislodged from the connecting member housing surface.

18 . The apparatus of claim 11 , wherein the reservoir connecting surface comprises a second protrusion member configured to contact a second weakened region having a third switch contact surface on the connecting member housing surface, wherein the second weakened region is configured to breakaway when contacted by the second protrusion member.

19 . The apparatus of claim 11 , comprising an elongated tube, wherein a distal end of the elongated tube is removably connected to the connecting member housing, and a top end of the connecting member housing is connected either directly or indirectly to the dispenser head.

20 . A system for monitoring a refill status for a liquid product dispensing apparatus, the system comprising:
a connecting member housing having a reservoir connecting surface, the reservoir connecting surface including a switch having a first switch contact surface disposed within a protrusion member; a container housing for holding a quantity of a liquid product, the container housing configured to be removably attached to the connecting member housing, the container housing comprising a main container and a connecting member housing surface, the connecting member housing surface having a second switch contact surface configured in a first weakened region, wherein after contact of the first switch contact surface and the second switch contact surface, the protrusion member is configured to engage the first weakened region such that the first weakened region breaks away from the connecting member housing surface such that first switch contact surface and second switch contact surface are unable to make contact; control circuitry and/or one or more sensors operably configured to communicate a dispense count, wherein upon contact of the first switch contact surface and the second switch contact surface the dispense count is set to zero; and a computing system operably configured to receive and track the dispense count and generate a refill status upon reaching a threshold dispense count.
