Closure having band with internal thread formed by impression
First Claim
1. A composite closure for mating with a container having a finish that includes threads formed thereon, the closure comprising:
- a flange;
a skirt depending downwardly from a periphery of the flange and including a protrusion extending from an interior surface of the skirt, the skirt comprising a first material;
an insert disk disposed within the skirt and substantially beneath the flange; and
a molded deformable element disposed on the interior surface of the skirt below the protrusion, the deformable element being spaced apart from the insert disk such that the insert disk is floatable, the deformable element comprising a second material and being deformable by the container threads to impress closure threads into the deformable element, the skirt protrusion is configured to restrict axial deformation of the deformable element towards the flange upon mating the closure with the container.

Abstract
A closure for mating with a container has a threaded finish. The closure comprises a flange and a skirt downwardly depending therefrom. The skirt includes a deformable element formed of a different material than that of the flange and skirt and disposed on an interior surface. The deformable element inner diameter is smaller than the outer diameter of the container, and accordingly deforms upon mating the closure with the container. The container threads impress threads into the deformable element to form threads on the closure. The deformable element is formed of a suitable material. The closure of the present invention provides for the use of high-speed press-on capping equipment.

13. A closure for mating with a container having a finish that includes a thread thereon, the closure comprising a body and a deformable element, the body comprising:
-
a flange; a skirt depending downwardly from a periphery of the flange; and at least one passage extending from an exterior surface of the body to an interior surface of the body and at least partly through the skirt; the deformable element being disposed on an interior surface of the skirt, the deformable element having at least one branch disposed within the at least one passage, whereby the deformable element is formed by injecting material through the at least one passage. - View Dependent Claims (14, 15, 16, 17, 18, 19, 29, 30, 31, 32, 33)

20. A method for closing a package, comprising the steps of:
-
providing a container having a finish with threads disposed thereon, the threads having an outer diameter; providing a closure comprising a flange, skirt depending downwardly from a periphery of the flange and including a protrusion extending from an interior surface of the skirt, and a deformable element disposed on an the interior surface of the skirt below the protrusion and spaced apart from the flange, the deformable element having an inner diameter that is smaller than the outer diameter of the finish threads, the skirt comprising a first material and the deformable element comprising a second material; and urging the closure onto the container finish such that the deformable element is deformed by the container thread to impress closure threads in the deformable element, such that the skirt protrusion restricts deformable element movement axially towards the flange during the urging step, and such that the deformable element remains spaced apart from the flange. - View Dependent Claims (21, 22, 23, 34, 35, 36, 37, 38, 39)
