Urisheath with moulded unrolling strip
The urisheath provided here includes an element of thin material (a strip) that allows at least two lengths of it to run in a parallel fashion down either side of the sheath. The is obtained by injection molding the strip in liquid silicone in the silicone injection molding process for the urisheath, either by one, two or more component injection molding. The injection molding takes place in an injection molding form for a urisheath with a cavity for the body portion and a cavity for the strip portion wherein the cavity for the body portion is connected to the cavity for the strip portion creating an attachment zone between the strip and the sheath.
1. A method for producing a urisheath comprising:
providing a moulding form adapted for injection moulding;
injecting silicone into the form;
curing the silicone, thereby defining the urisheath, the urisheath comprising a body portion, the body portion comprising:
a root part, a centered part, and a tip part; and
a strip portion attached to the body portion in an attachment zone, the attachment zone comprising a weakened zone;
releasing the product from the moulding form; and
rolling the urisheath to include the strip portion.
2. An injection moulding form for a urisheath comprising: a cavity for a body portion, the body portion comprising a root part, a centered part, and a tip part;
a cavity for a strip portion; and
a cavity for an attachment zone connecting the strip portion to the body portion, adapted such that the attachment zone comprises a weakened zone.
3. The injection moulding form according to claim 2 , wherein the cavity for the strip portion comprises a cavity defining one strip.
4. The injection moulding form according to claim 3 , wherein the connection between the cavity for the strip portion and the cavity for the body portion is at the root part.
5. The injection moulding form according to claim 4 , wherein the form comprises three solid parts: a core part, an upper shield part and a lower shield part.
6. The injection moulding form according to claim 5 , further comprising a cavity for a handle.
7. The injection moulding form according to claim 6 , wherein the handle cavity is formed between the upper shield part and the lower shield part.
8. The injection moulding form according to claim 6 , wherein the handle cavity is formed within one of the upper shield part and the lower shield part.
9. The injection moulding form according to claim 6 , wherein the handle cavity is formed between one of the upper shield part, the lower shield and a 4 th form element.
10. The injection moulding form according to claim 2 , wherein the cavity for the strip portion comprises two strips.
11. The injection moulding form according to claim 10 , further comprising a cavity for a handle connecting two strips.
12. The injection moulding form according to claim 11 , wherein the handle cavity is formed between the upper shield part and the lower shield part.
13. The injection moulding form according to claim 11 , wherein the handle cavity is formed within one of the upper shield part and the lower shield part.
14. The injection moulding form according to claim 11 , wherein the handle cavity is formed between one of the upper shield part, the lower shield and a 4 th form element.
