Abstract

An article includes an adapter having a flow channel extending through it, where the adapter includes a base, a neck, a bendable segment attached to the base and neck and positioned between the base and neck, and a plunger attached to the neck or bendable segment and extending within the flow channel in the bendable segment.

First claim

What is claimed is:

1. An article comprising an adapter ( 10 ), the adapter comprising a base ( 20 ), a neck ( 40 ) and a bendable segment ( 30 ) connecting the base and the neck and having a flow channel ( 50 ) extending all the way through the base, bendable segment and neck, the adapter further comprising a plunger ( 60 ) attached to the neck or bendable segment and extending within the flow channel of the bendable segment towards and optionally into the flow channel of the base, where:
(a) the base has opposing bottom ( 22 ) and top ( 24 ) ends with a base side wall ( 26 ) extending between the bottom and top with the flow channel extending through an entrance opening ( 23 ) defined through the bottom and extending between the top and bottom;
(b) the bendable segment has opposing bottom ( 32 ) and top ( 34 ) ends with a bendable segment side wall ( 36 ) extending between the bottom and top with the bottom attached to the top of the base so that the flow channel extends top and bottom of the bendable segment within the bendable segment side wall, where the bendable segment side wall comprises a compressible feature ( 38 );
(c) the neck has opposing bottom ( 42 ) and top ( 44 ) ends with a neck side wall ( 46 ) extending between the bottom and top with the bottom attached to the top of the bendable segment so that the flow channel extends between the top and bottom of the neck, within the neck side wall and through an exit opening ( 45 ) defined through the top of the neck; and
(d) the plunger is of dimensions and/or design so as to allow fluid communication around and/or through it within the flow channel;

wherein the flow channel extends in a straight line from the entrance opening of the base through the exit opening of the neck when in its neutral position.

2. The article of claim 1 , wherein the adapter is free of a trigger feature protruding radially out from the adapter relative to a line defined by the flow channel when the bendable segment is in its neutral position.

3. The article of claim 1 , wherein the base has threads ( 28 ) defined on an outer surface of the base side wall; defined on an inner surface of the base side wall within the flow channel proximate to the entrance opening of the base; or defined on the outer surface of the base side wall and on the inner surface of the base side wall within the flow channel proximate to the entrance opening of the base.

4. The article of claim 1 , wherein the neck has threads ( 48 ) defined on an outer surface of the neck side wall.

5. The article of claim 1 , wherein the compressible feature defined in the bendable segment side wall is a corrugated section of the bendable segment side wall.

6. The article of claim 1 , wherein the article further comprises a can ( 100 ) having a valve ( 110 ) that comprises a valve cup ( 120 ) around a stationary valve stem housing ( 130 ) in which a depressible valve stem ( 140 ) resides and that extends out from or is accessible through only a top side ( 132 ) of the stationary valve stem housing and where the adapter is attached to the can such that the base of the adapter is fit within the valve cup with the stationary valve stem housing and depressible valve stem extending through the entrance opening in the base of the adapter into the flow channel of the adapter and further characterized by the plunger extending far enough down in the flow channel so as to depress the depressible valve stem and open the valve when the bendable segment of the adapter is tilted to its tilted position relative to the base and yet not so far so as to depress the depressible valve stem and open the valve when the bendable segment of the adapter is in its neutral position.

7. The article of claim 6 , wherein the adapter base attached to the valve is free of any portion that fastens to the valve cup by extending over the top of the valve cup.

8. The article of claim 6 or 7 , wherein the base of the adapter has threads ( 28 ) defined on an outer surface of the base side wall that engage mating threads ( 128 ) in the valve cup.

9. The article of claim 1 , wherein the article further comprises a dispenser ( 200 ) attached to the adapter, the dispenser having a flow channel ( 210 ) therethrough from an entrance end ( 220 ) to an exit end ( 230 ) and that is removably attached to the neck of the adapter at the entrance end of the dispenser, where threads ( 48 ) are defined on an outer surface of the adapter neck side wall that are engaged with mating threads ( 240 ) defined on an inner surface of the dispenser within the flow channel proximate to the entrance end of the dispenser.

10. The article of claim 9 , wherein the dispenser comprises a trigger protrusion ( 250 ) extending radially relative to its flow channel.
