Abstract
A flange member for sealing a mouth extending from a reservoir, includes an annular body for receiving and connecting with the mouth of the reservoir, and a membrane coupled to a flange surface defined at a distal end of the annular body.
Claims23
A reservoir and flange member combination comprising:
- a reservoir;
- a mouth extending from the reservoir, said mouth comprising an annular wall;
- a flange member connected to the mouth comprising an annular body having an inner surface, and an annular flange surface defined at a distal end of the annular body, wherein the annular body is connected to the annular wall and extends coaxially with the annular wall;
- and
- a membrane coupled to the annular flange surface, wherein a projection extends radially outward from the annular wall and a groove extends radially inward from the inner surface of the annular body into the annular body, wherein the annular body surrounds at least an axial portion of the annular wall and wherein the projection extending from the annular wall is received in the groove extending in the annular body for connecting the flange member to the mouth, wherein the groove comprises a first section, a second section, and a third section, wherein the first section defines a first step, wherein the second section tapers from the first section to the third section reducing in diameter in a direction toward the third section, and wherein the third section extends from the second section and in a direction axially away from the first and second sections and defines a second step.
