Definitions
- This invention relates to an improved liquid-tight fastener for cans, which comprises the can filling port, a cap provided upperly with a sealing surface and an annular projection, and finally a ring nut.
- a liquid-tight seal must be able to be attained even with cans produced by economical moulding means, i.e. starting from a plastics tube which is hot-deformed with compressed air in a suitable mould, until it takes the form of the mould.
- the resultant filling ports have fairly thin walls, an irregular thread and a high tendency to liquid loss through the fastener, when relatively low pressures are exceeded.
- a cap provided upperly with a sealing surface, and with an annular projection; the cap is inserted into the can filling port and a ring nut is then screwed over the filling port after positioning an 0-ring at the end of the port.
- the 0-ring is preferably of nylon.
- the ring nut and cap can be of suitable thermoplastic material, for example nylon, or can be of metal.
- the filling port has been designed for the simultaneous patent application in the name of the present applicant entitled: "Containers for distributors of liquids for spraying on to hay and other agricultural products", and for this reason 1 ⁇ 4" male threaded connectors are shown for the compressed air 5 and for the pressurised liquid 6.
