US 2006/0141838 A1 · Method for manufacturing a socket

Abstract

In a method for manufacturing a socket for connecting a fluid conduit to a container made from thermoplastic synthetic material, wherein the socket has a first socket-shaped material arrangement of at least one layer and a second socket-shaped material arrangement of at least one layer, wherein the first material arrangement is thinner than the second material arrangement and the first and second material arrangements are both made of thermoplastic material at least predominantly and fuse with one another to form a fused joint, the first material arrangement is molded by extrusion or injection molding to a plane film or plate or to a hose. The film or plate is deepdrawn or the hose is blowmolded to a first preform with a socket contour. The second material arrangement is applied onto one side of the first preform in a socket contour by injection molding, coinjection or a monosandwich process.

A method for manufacturing a socket for connecting a fluid conduit to a container made from thermoplastic synthetic material, wherein the socket has a first socket-shaped material arrangement comprising at least one layer and a second socket-shaped material arrangement comprising at least one layer, wherein the first material arrangement is thinner than the second material arrangement and the first and second material arrangements both comprise a thermoplastic material at least as a predominant component and fuse with one another to form a fused joint;

the method comprising the steps of:
1) molding the first material arrangement by extrusion or injection molding to a plane film or plate or to a hose;
2) deepdrawing the film or the plate or blowmolding the hose to a first preform with a socket contour;
3) applying the second material arrangement onto one side of the first preform in a socket contour by injection molding, coinjection or a monosandwich process.

1 more element

A method for manufacturing a socket for connecting a fluid conduit to a container made from thermoplastic synthetic material wherein the socket has a first, a second, and a third material arrangements having rotational symmetry, wherein the first, second, and third material arrangements each are comprised predominantly of thermoplastic synthetic material, wherein the first material arrangement comprises at least one layer and surrounds the second material arrangement, wherein the third material arrangement surrounds the first material, wherein the first, second, and third material arrangements are connected by a fused joint and form a flange of the socket facing the container, wherein the first material arrangement and the second material arrangement extend to a surface of the flange to be connected to the container;

the method comprising the steps of:
1) molding the first material arrangement by extrusion or injection molding to a plane film or plate or to a hose;
2) deepdrawing the film or the plate or blowmolding the hose to a first preform with a socket contour;
3) applying the second material arrangement by injection molding onto one side of the first preform;
and
4) injection molding in the area of the flange the third material arrangement about an end section of the first and second material arrangement which end section is facing away from a surface of the flange to be connected to the container.

3 more elements

the method comprising the steps of:
1) molding a preform of one of the first and second material arrangements in a first mold cavity, wherein the preform has a socket contour;
2) molding the other one of the first and second material arrangements in a second mold cavity onto the preform, wherein the thermoplastic synthetic material of one of the first and second material arrangements that contacts the fluidline when it is connected by the socket to the container comprises an electrically conducting additive.
