Reclosable dispenser package, reclosable outlet forming structure and method and apparatus for making same

An aperture forming means comprising a protrusion which is cylindrical, said protrusion being formed from thermo-formable plastic with one integral covered end, said covered end having a fault line pattern which pattern, when pressed into a space defined by said protrusion, ruptures in a predetermined pattern to create a predetermined aperture.

An aperture forming means comprising a thermo-formed member having a hollow frusto-conical protrusion from a surface atop a hollow cylindrical based member wherein an intersection of said hollow frusto-conical protrusion with said surface atop said hollow cylindrical based member comprises a locus of a fault line to create a break away tip with an adjacent tethered cap member, said break away tip and said tethered cap member being securely sealingly attached to a container wherein said cylindrical based member is located directly over a hole in said container.

Apparatus to form a hollow protrusion from heated thermoplastic film where said hollow protrusion intersects said heated thermoplastic film, said entire intersection comprising the locus of a fault line, including:

• (a) punch means comprising a tip portion with a shallow frusto-conical formation at the base of said tip portion;
• and
• (b) a female die having an accurately bored hole in a flat die block, said hole of slightly larger diameter than the base of said tip portion of said punch means, so dimensioned that when said punch means is introduced into said female die when forming said heated thermoplastic film the base rim, if advanced to contact said frusto-conical formation, the locus of such contact would be a circle located approximately centrally between the larger base circle and the smaller end circle of the frusto-conical formation.

Apparatus to form a hollow protrusion from heated thermoplastic film where said hollow protrusion intersects said heated thermoplastic film, said entire intersection comprising the locus of a fault line, which hollow protrusion extends from a closed hollow essentially cylindrical base portion, including:

• (a) punch means comprising a tip portion with a shallow frusto-conical formation at the base of said tip portion;
• (b) a spring loaded self-centering retractable female die member configured to mate with said punch means, and
• (c) a spring loaded film clamp means with a central hole through which said punch member may pass, cylindrical means extending from said central hole whose outer diameter functions as a punch means to form the inside diameter of the closed hollow essentially cylindrical base portion and whose height forms the inner height of said protrusion when cooperating with said female die member.

Apparatus to form a hollow tapered protrusion from heated thermoplastic film where a fault line may be formed encircling an outer surface of said protrusion at various predetermined heights including:

• (a) punch means comprising a tapered tip extending from a round shaft member;
• (b) a film stop plate with a hole so sized as to permit said punch means and said heated thermoplastic film being formed to pass through to reach a female die means;
• (c) female die means comprising a bored die block, said bore to be of such diameter as to locate the fault line on the outer surface of the tapered member protrusion at a predetermined location when cooperating with said punch member.
