Abstract: A one-piece molded flexible plastic material golf club headcover for use with a golf club, including a golf club head and shank, is disclosed. The golf club headcover includes a golf club headcover section for substantially surrounding the golf club head. A flexible and resilient restricted throat is formed in the golf club headcover section which has an internal dimension smaller than the golf club head such that upon insertion of the golf club head, the flexible and resilient restricted throat deforms and expands to allow passage of the golf club head into the golf club headcover section and subsequent return to its initial configuration. Locking elements are formed in the golf club headcover section independent of the flexible and resilient restricted throat for underlying the golf club head while releasably holding the golf club headcover section on the golf club head.

Abstract: A golf club shaft protector is disclosed as including a hollow plastic tube of predetermined diameter and length with open upper and lower ends. The length of the hollow plastic tube substantially corresponds to the length of a golf club shaft and can be pre-selected and cut to the appropriate length. A flexible restricted throat element extends across the open upper end of the hollow plastic tube for resilient deformation upon the insertion of a golf club handle to allow passage of the golf club handle and associated golf club shaft into the hollow plastic tube. The flexible restricted throat element subsequently returns to its initial shape for close fitting circumferential support of the golf club hosel at an upper end of the golf club shaft adjacent the golf club head. The predetermined diameter of the hollow plastic tube is dimensioned to at least substantially peripherally engage the golf club handle at least adjacent the open lower end.

Abstract: A dip molding process for making an integral article having a solid inner surface and a foamed outer cover in which a hot mold is dipped into a solid plastisol which is partially fused before being dipped into a foamable plastisol which is then formed, fused and bonded to the solid plastisol to form an integral article.

Abstract: A dip mold for forming a part from plastisol which part has an integral internal member. The dip mold has an internal cavity in its free end to form said internal member and the cavity is vented by a lateral passage to the outside face of the mold to allow air in the cavity to escape and the internal molded part to be formed.

Abstract: A one-piece plastic insulated beverage receptacle holder having longitudinal side panels, one of which is wider than the remainder and recessed to accommodate ad copy or the like.
