Abstract

Disclosed is an improved an improved cap ( 40 ) for a bottle ( 1 ) which comprises a frangible device interface ( 100 ) including a valve part ( 52 ) and a tethered pull-ring ( 70 ), which frangible device interface may be removed from the cap preferably after the contents of the bottle are exhausted.

First claim

The invention claimed is:

1. A cap for a bottle which includes a frangible device interface comprising a valve part;
wherein the bottle contains a liquid or gel product and has a neck upon which is mounted the cap, the cap comprising an interior cavity defined by an annular sidewall, a valve plate, and a cap face;
wherein the valve plate includes a liquid outlet leading from the interior of the bottle into the interior cavity, the liquid outlet having an annular wall surrounding a central bore, an outlet valve element, and further depending from the valve plate is a tethered pull-ring which is recessed within the interior cavity, wherein the valve plate further includes a pressure relief valve; and
wherein the cap further includes a channel intermediate the annular sidewall and the valve plate and which defines a frangible region of reduced thickness in the material forming the cap.

2. The cap for a bottle according to claim 1 , wherein the outlet valve element is biased against onto the annular wall by one or more biasing elements.

3. A dispenser for dispensing liquid or gel product, the dispenser including a refill unit containing a quantity of the product to be dispensed, and a base unit through which the product is dispensed, wherein the base unit includes a receptacle part, configured to form a housing for receiving a part of a refill unit which comprises a cap according to claim 1 mounted on a bottle containing the liquid product, the receptacle part including a base and an upwardly projecting spigot which at a proximate end thereof includes one or more castellations and one or more passages, wherein the spigot is engaged within the central bore of the outlet and displaces the outlet valve element away from the valve seat.

4. The cap for a bottle according to claim 1 , wherein the cap includes a frangible device interface including a valve which is capable of being manually removed or otherwise disassembled from the cap in order to separate it from the cap, and wherein the cap is capable of being separately recycled from the frangible device interface.

5. A refill unit comprising a cap according to claim 1 , wherein the cap includes a frangible device interface including a valve which is capable of being manually removed or otherwise disassembled from the cap in order to separate it from the cap, and wherein the refill unit comprising the cap is capable of being separately recycled from the frangible device interface.
