Abstract
An ice bag is described having a bladder formed with an opening, a threaded receiver coupled to the bladder at the opening, a threaded cap having a first portion formed of a rigid material and a second portion formed of an overmold material, the second portion providing a seal between the receiver and cap with the cap threaded into the receiver.
Claims18
A cap comprising;
- a first portion formed of a rigid material, said first portion having a hollow cylindrical portion with an outer cylindrical surface having threads formed on a portion of the outer cylindrical surface, a flange having a first side and an opposed second side, the flange extending outwardly from the outer cylindrical surface, and at least two ribs, each rib having a curved surface extending from a location on the second side of the flange to a location on the outer cylindrical surface, the first portion formed with a through-hole in said flange;
- and
- a second portion formed of an overmold material, the second portion extending through the though-hole and establishing a seal on the first side of the flange and overlying a surface of the second side of the flange with the second portion extending between the ribs to establish a mechanical anchor for the seal.
A threaded cap for covering an opening of a container and providing a seal between the cap and the container, the threaded cap comprising;
- a rigid portion having a threaded cylinder with a cover overlaying a first cylinder end and a flange having a first side and a second side, the flange extending from the threaded cylinder, the flange formed with a through-hole, the flange second side and cover establishing a first surface having raised portions and recessed portions;
- and
- an elastomeric portion extending through the though-hole and overlaying the recessed portions of the first surface to establish an anchor for the seal having an annular portion and at least one connecting portion, the connecting portion extending from a first location on the annular portion to a second location on the annular portion and overlying at least a portion of the first side of the flange.
A method for producing a cap comprising the steps of;
- molding a first threaded component formed of a rigid material, said first component having a hollow cylindrical portion with an outer cylindrical surface having threads formed on a portion of the outer cylindrical surface, a flange having a first side and an opposed second side, the flange extending outwardly from the outer cylindrical surface, and at least two ribs, each rib having a curved surface extending from a location on the second side of the flange to a location on the outer cylindrical surface, the first threaded component formed with a through-hole in said flange;
- and
- overmolding a thermoplastic elastomer material on the first threaded component, the thermoplastic elastomer material extending through the though-hole and establishing a seal on the first side of the flange and overlying a surface of the second side of the flange with the second portion extending between the ribs to establish a mechanical anchor for the seal.
