Abstract

A medical device includes a body having a first end and a second end positioned opposite the first end, with the body defining an opening extending from the first end and including a sealing surface extending radially outward from the opening. At least a portion of the sealing surface includes a non-circular perimeter pattern.

Claims (19)

1 . A medical device comprising:

a body having a first end including a flange extending radially outwardly from the body to an outer edge and a second end positioned opposite the first end, the body defining an opening extending from the first end and including a sealing surface extending radially outward from the opening, and the body including a plurality of ribs extending radially outwardly from the body in a direction from the flange to the second end;

at least a portion of the sealing surface on the flange including a non-circular perimeter pattern co-planar with the sealing surface, extending to the outer edge and a plurality of recessed areas on the flange defined between the non-circular perimeter pattern and the outer edge; and

a packaging film thermally sealed to the sealing surface that extends radially outward from the opening and the non-circular perimeter pattern configured to ensure flash defects created during thermal sealing of the packaging film remain connected to the body of medical device and provide a plurality of stress concentration points to prevent formation of plastic strings or debris during separation of the packaging film from the sealing surface caused by the flash defects.

2 . The medical device of claim 1 , wherein an entirety of the sealing surface includes the non-circular perimeter pattern.

3 . The medical device of claim 1 , wherein the body contains disinfecting fluid in the opening.

4 . The medical device of claim 1 , wherein the non-circular perimeter pattern comprises a sawtooth shape.

5 . The medical device of claim 1 , wherein the non-circular perimeter pattern comprises a plurality of triangles, with a plurality of triangle-shaped recessed areas defined between the non-circular perimeter pattern and an outer edge of the first end of the body.

6 . The medical device of claim 1 , wherein at least a portion of the plurality of stress concentration points are positioned at the outer edge of the first end of the body.

7 . The medical device of claim 1 , wherein the medical device comprises a disinfecting cap, and wherein the second end of the body is closed.

8 . The medical device of claim 7 , wherein an inner surface of the opening of the body is threaded.

9 . The medical device of claim 1 , wherein the packaging film forms a fluid tight seal with the body.

10 . A medical device comprising:

a body having a first end including a flange extending radially outwardly from the body to an outer edge and a second end positioned opposite the first end, the body defining an opening extending from the first end and including a sealing surface extending radially outward from the opening;

at least a portion of the sealing surface on the flange including a plurality of recessed areas formed around a perimeter of the sealing surface that extends radially outward from the opening and positioned at the outer edge of the first end; and

a packaging film thermally sealed to the plurality of recessed areas and the sealing surface that extends radially outward from the opening, the plurality of recessed areas configured to ensure flash defects created during thermal sealing of the packaging film remain connected to the body of medical device and provide a plurality of stress concentration points to prevent formation of plastic strings or debris during separation of the packaging film from the sealing surface caused by the flash defects.

11 . The medical device of claim 10 , wherein each recessed area of the plurality of recessed areas is rectangular.

12 . The medical device of claim 11 , wherein each recessed area of the plurality of recessed areas is sloped.

13 . The medical device of claim 11 , wherein the plurality of recessed areas is a plurality of evenly spaced recessed areas.
