Benefits of technology

[0010] The present invention also describes a container comprising the threaded lock connector assembly disclosed herein. Preferably, the molded glass surface portion is a drinking cup. Also preferred, the engagement piece of the threaded assembly is a base and more pr...

Problems solved by technology

However, there are problems with these conventional lids.
Because the underside of the lid has a mechanical fastener, it is not a smooth surface and therefore it is difficult to clean.
Such a construction, however, is not economical for entry-level products because of the additional cost associated with shipping and labor in a...

Embodiment Construction

[0022] Reference will now be made in detail to presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0023]FIG. 1 shows a prior art lid 1 made of sag glass that has an opening 6 cut into it for attaching a knob 8. A stainless steel screw 2, a stainless steel washer 4 and a rubber washer 5 are placed through the opening 6 from the underside of the lid 1.

[0024] FIGS. 2 to 5 show a first preferred embodiment of a molded glass lid 16 according to the present invention. In this embodiment, the molded glass lid 16 has an exterior surface portion 18 and an externally threaded post 10 disposed on said surface portion 18, threaded post 10 being formed integrally with surface portion 18. It is also preferred that the externally threaded post 10 is disposed on a center position of the exterior surface portion 18.

[0025] The molded glass lid 16 preferably further comprises an internally threaded knob 12 having an internal diameter tha...

Abstract

A pressed glass lid with an attachable knob. A threaded post is molded in glass for purposes of attaching a knob. The threaded post is integrally formed on a surface portion of a lid. The surface portion may be a lid or formed of a conical body. The internal threaded channel of the knob has a diameter greater than the diameter of the threaded post.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application relates to U.S. Provisional Patent Application No. 60 / 509,938, filed on Oct. 10, 2003, the contents of which are hereby incorporated by reference herein in their entirety.FIELD OF THE INVENTION [0002] The present invention relates to a threaded assembly system and more particularly, to a molded threaded post configuration that engages an internally threaded object. BACKGROUND OF THE INVENTION [0003] Prior art methods for making glass knob / lid configurations typically involve either the use of sag glass and a mechanical means for attaching a knob to the lid, or the use of pressed glass that has a glass knob directly molded into the lid. However, there are problems with these conventional lids. For example, the sag glass lid often comprises a centrally located hole through which a screw is inserted that affixes the knob to the lid. Because the underside of the lid has a mechanical fastener, it is not a smooth surface and ...
