Container for refilling small bottle - has spring-biased valve in sleeve with valve nose being contacted by stop in neck of bottle

摘要

The container (1) is used to re-fill small bottles (20) and has a valved cap (5) mounted on its neck (2). The valve (6) is held on its seat by e.g. a spring (10), the cap having a hollow cup-like tip (5b) for housing onto the head (22) of the bottle. A stop (21) is built into the neck of the bottle and a valve-nose (6b) projects into the tip, the stop contacting the nose to urge the valve back off its seat. The cap may be held in place by screwing or clipping, the spring being retained by a neck rebate (3) whilst the seat (7) extends a sleeve (13) locating the valve-nose. The valve may project from an oversize base plate (6c) which contacts the seat and the spring.
