Tamper evident closure assemblies
A sipper type capping assembly engageable with a necked container so as not to pool condensation on the disc seal. It has a unitary molding ( 1 ) adapted to define a detachable overcap ( 4 ) and at least the container engaging skirt ( 9 ). An insert ( 2 ) and a disc seal member ( 17 ) located within molding ( 1 ), and a nozzle component ( 3 ) above the seal member is carried through the insert yet moveable relative thereto. In a non-dispensing condition, the nozzle component ( 3 ) and the insert ( 2 ) provide closure. In the dispensing condition of the nozzle component ( 3 ) relative to the insert ( 2 ) there is defined a liquid egress passageway. The insert and the nozzle component, when in or notionally considered in the non-dispensing condition, define together with the molding a fully enclosed space about part of the nozzle component. When in or notionally considered in at least the dispensing condition, the molding and the disc seal member fully enclose the nozzle component.
1. A capping assembly engageable with or engaged with a necked container, said capping assembly comprising
a first component in the form of a unitary moulding adapted to define a detachable overcap and at least a skirt, the skirt being adapted to engage or engaging an exterior of a neck of said container,
a second component at least in part located within said first component, and
a nozzle component carried through the second component yet moveable relative to the second component such that,
in one relative condition, the non-dispensing condition, the nozzle component together with the surrounding second component, is adapted to provide closure of the mouth of said container or provides closure of the container,
in another condition, the dispensing condition, of the nozzle component relative to the second component, is adapted to provide said container, or provides for the container, a liquid egress passageway,
the second component and the nozzle component, when in the non-dispensing condition, define together with the first component a fully enclosed space about part of said nozzle component,
said first component including a tear strip or other frangible feature whereby the detachable overcap is separated from the skirt thereby to allow access to a part of said nozzle component presenting to said fully enclosed space about part of said nozzle component.
2. The capping assembly of claim 1 , wherein said skirt of the first component is internally threaded as the adaptation to engage or the means by which it is engaged with the exterior of the neck of said container.
3. The assembly of claim 1 , wherein when not in the non-dispensing condition the nozzle component is above a disc seal of a mouth of the container.
4. The assembly of claim 1 , wherein in the non-dispensing condition, the container is carried fully below the nozzle component and the second component within the first component.
5. The assembly as claimed in claim 1 , wherein said detachable overcap, once separated from a remainder of the first component is adapted to engage with said second component or skirt.
6. The assembly of claim 5 , wherein said overcap is adapted to engage with the second component whereby the second component and the nozzle component, when in the non-dispensing condition, define together with the overcap a fully enclosed space about part of said nozzle component.
7. The assembly of claim 1 , wherein the skirt has a shoulder peripherally overlapping as a hold down of a complementary shoulder of the second component.
8. The assembly of claim 1 wherein the first component unitary moulding defines a tamper evident collar or a tamper band dependent from said skirt and/or as an extension of the skirt.
9. The closured container assembly comprising a necked container closed by a capping assembly of claim 1 .
