Abstract
A squeezable bottle containing fluids has a mouth for dispensing the fluid. An elastic valve is retained between a closing support retainer and a containment ring. The closing support retainer is secured to the mouth of the bottle and to the elastic valve and has passages for fluid through itself. The containment ring prevents the elastic valve from expanding too far outwardly over at least some of the valve's surface. A fluid passage is formed between the elastic valve and a rigid cap that leads to a dispensing opening. The dispensing opening is sealed by a round disc which is integrally formed with the elastic valve and seats on seat on the cap. This arrangement allows the contents of the bottle to remain sanitary over time.
Claims29
A bottle for containing fluids, comprising;
- a fluid container made of a deformable material and which includes a mouth for passage of said fluid,
- a valve of an elastically deformable material that defines a flexible inner chamber arranged in proximity of said mouth,
- a cap that substantially fits on and seals said valve and which has a dispensing opening for dispensing said fluid and a seat downstream of said dispensing opening, the squeezing of the container causing fluid therein to push up towards the mouth, the valve to compress, the fluid to flow between the valve and cap and to come out through said dispensing opening,
- a containment ring placed between said cap and said valve and arranged to externally embrace at least one portion of said valve and able to limit deformation thereof, and
- a check valve body attached to said valve and which extends through said dispensing opening and includes a disc which can contact said seat to close said discharge opening.
