DESCRIPTION:
BRIEF SUMMARY
DESCRIPTION OF INVENTION
This invention relates to a dispenser for dispensing predetermined amounts of a liquid or a soft extrudable material.
In particular, the invention is concerned with a dispenser of the kind, hereinafter referred to as the kind specified, which is adapted to hold a collapsible or deformable container which contains a liquid or a soft extrudable material and has a nozzle through which material can be discharged by squeezing the container, the dispenser being operable to squeeze the container to dispense predetermined amounts of liquid or material.
The dispenser of the invention has been devised for dispensing toothpaste from a container in the form of a collapsible tube which is closed at one end and has a discharge nozzle at its other end, and the following description will therefore be confined to this application of the invention. However, it is to be understood that there is no limitation in this regard since the dispenser may be used to dispense other soft extrudable materials such, for example, as grease, sealing compound and adhesive as well as liquids such, for example, as liquid soap.
According to the invention there is provided a dispenser of the kind specified which is operable to dispense a liquid or a soft extrudable material from a container held by the dispenser, by subjecting the container to hydraulic pressure thereby to squeeze the container.
The dispenser preferably comprises a housing defining a chamber to receive the container, the chamber having an opening for the discharge of liquid or material from the nozzle of the container and being connected to means operable to supply hydraulic fluid under pressure to the chamber. These means preferably comprise a reservoir of hydraulic fluid and a piston operable to force fluid from the reservoir into the chamber.
The dispenser may be designed for mounting in a fixed position, for example on a wall, or it may be hand-held.
The invention will now be described, by way of example, with reference to the accompanying drawing which is a vertical section, partly cut away, of one form of dispenser embodying the invention.
The dispenser illustrated in the drawing has been designed for dispensing predetermined amounts of toothpaste from a collapsible tube T which is closed at one end E and has a nozzle N at its other end through which toothpaste can be discharged by squeezing the tube. The nozzle is screw-threaded to receive a closure cap (not shown) which is removed before the tube is placed in the dispenser.
The dispenser comprises an elongate, cylindrical housing 10 formed to provide a chamber 11 at one end in which the tube is mounted, and a chamber 12 at the other end to contain a reservoir of water, the two chambers being separated by a partition 13 formed with two bores 14, 15.
The housing 10 is provided with a mounting plate 16 enabling the dispenser to be mounted in a vertical position, as shown in the drawing, on, for example, a wall in a bathroom, the plate being fixed to the wall by, for example, adhesive or screws. The housing 10 is provided with a longitudinally extending tongue 17 of T shape in cross-section, the limb of the tongue being connected to the housing and the cross-piece being engaged in a longitudinally extending, complementarily shaped groove formed in the mounting plate. The groove is open at its upper end to enable the lower end of the tongue to be engaged in it whereupon the tongue is slid downwardly into position, the lower end of the groove being closed to provide a stop for the lower end of the tongue. The lower end of the tongue is tapered and the lower part of the groove is similarly shaped so that the tongue becomes a tight fit in the groove when it reaches the end of its downwards movement. The mounting plate may be formed to hold a tumbler and tooth brushes.
The lower end of the housing is in the form of a screw-threaded cap 18 formed with a central opening through which the nozzle N of the tube T extends, the opening being provided with an annular seal 19 for sealing engagement with the nozz
