Claims29
A device having a body comprising a cavity and a fluid port made of a thermoplastic elastomer adhering to the body.
A method for manufacturing a device having a body comprising a first, rigid material comprising a cavity with an opening closed by a fluid port being of a second, elastic material, comprising
- a first molding step including
- a) providing a first mold reflecting an shape of the rigid body,
- b) injecting into the first mold the first material in liquefied form,
- c) waiting until said first material has become at least partially solid,
- providing the result of said first molding step in a second mold a first part of which reflects an outer form of said fluid port and a second part reflecting at least a part of the first mold,
- a second molding step including
- a) injecting into the first part of said second mold the second material in liquefied form,
- b) waiting until the second material has become at least partially solid, and
- removing the result of said molding steps from said mold after solidification of said materials.
