摘要： A bi-directional filter drier is provided for reverse flow applications as encountered, for example, in heat pump systems. The filter drier includes a shell defining a chamber, the shell having an inlet and an outlet, preferably axially aligned with one another, which communicate with the chamber. A suitable filter means is positioned in the chamber and a fluid flow path within the chamber is designed so that fluid flow through the filter always occurs in a single direction, regardless of the direction of flow through the inlet and outlet. Flow within the chamber and thus the filter is controlled by a simply constructed valve combination at the inlet and the outlet.

摘要： The all plastic can includes an upwardly extending open mouth portion with an inwardly tapering exterior surface and a molded plastic end closure member having an integrally formed rim portion extending downwardly therefrom. An outwardly tapering interior surface is provided on the rim and is inclined to mate with the inwardly tapering exterior surface of the open mouth portion of the can body. Relative rotation is imparted between the end closure member and the product filled can body so that spin-bond sealing connects the inwardly tapering exterior surface of the open mouth portion and the interior surface of the rim portion of the end closure member. An intergrally formed outwardly extending rib is provided on the inwardly tapering exterior surface of the open mouth portion to enhance the spin-bond between the end closure member and the can body. A bead of hot melt material is applied around the upper portion of the inwardly tapering exterior surface of the open mouth portion and serves to prevent entry into the interior of the product filled can body of any plastic dust particles generated by the spin-bonding of the end closure member to the can body. The spin-bonding of the end closure member provides a tamper evident closure for the can.
