The combination in accordance with claim 1 wherein the projecting means for said plunger comprises screw-means, said screw-means comprising in combination: a centrally disposed opening in said plunger, wherein said opening is internally screw-threaded; a screw-threaded stem mounted in axial relation in the base of said container and projecting upwardly in operative relation to screw-threaded opening; a cylindrical screw-knob attached in an axial relation to the lower end of said stem adjacent the base of said container; wherein said screw-stem is constructed and arranged to rotate in direct response to the manual rotation of said screw-knob; and wherein said plunger is propelled by said screw-threaded stem operating through said opening to move in an axial direction along the interior of said cylinder in response to rotation of said screw-knob.

Claim 7

The combination in accordance with claim 1 wherein: said cap is in the form of an inverted cup having a depending annular skirt, said cap being fastened in closed relation to said container by resilient snapping means comprising an annular ring disposed near the lower inner edge of said skirt, said ring constructed and arranged to engage an annular groove disposed near the upper outer edge of said container.

Claim 8

The combination in accordance with claim 1 wherein: said cap is in the form of an inverted cup having a depending annular skirt, being fastened in closed relation to said container by screw-means comprising internal screw-threads disposed near the lower inner edge of said skirt, constructed and arranged to engage external screw-threads disposed near the upper outer edge of said container.

Claim 9

The combination in accordance with claim 1 wherein: said means for filling said container comprises said open upper end through which molten product is poured and allowed to solidify.

Claim 10

The combination in accordance with claim 1 constructed to be filled in inverted position wherein: said means for filling said container comprises in combination: a centrally disposed opening in said plunger through which molten product is poured into said container when the same is held in inverted position, and allowed to solidify; a removable retainer cover having its peripheral edge clamped between the mouth of said container and an internally directed annular flange of said cap, said removable retainer constructed and arranged to retain said molten product; and a plug designed to seal said opening in said plunger after said container is filled; wherein said molten product solidifies while said container is in inverted position assuming the shape of the inner surface of said removable retainer cover.

Claim 11

The combination in accordance with claim 4 wherein: said means for filling said container in inverted position comprises in combination: a hollow lower end including a central tubular intake leading into a hollow lower portion of said screw-stem, said hollow portion having a lateral opening through which said molten product flows into said container and allowed to solidify; a retainer cover having its peripheral edge clamped between the upper peripheral edge of said container and an internally directed annular flange of said cap, said removable retainer cover constructed and arranged to retain said molten product; a plug designed to seal said opening in said plunger after said container is filled; and wherein said molten product solidifies while said container is in inverted position assuming the shape of the inner surface of said removable retainer cover.

Claim 12

A device constructed in accordance with claim 1 to enclose and dispense solid or semi-solid product comprising in combination: a hollow cylindrical container having an open upper end and a lower end which is at least partially closed; a removable cap in the form of an inverted cup having a depending annular skirt attached to, and sealing against said upper outer edge of said container by resilient snapping means; wherein said snapping means comprises an annular ring disposed near the lower inner edge of said skirt, constructed and arranged to engage an annular groove disposed near the upper outer edge of said container; and wherein said resilient snapping means is engaged by cam-action means comprising in combination: a plurality of V-shaped upper cams protruding from the inside wall, near the lower inner edge of said skirt; a plurality of inverted V-shaped lower cams protruding from the outside wall near the upper outer edge of said container; wherein, upon rotation of said cap relative to said container for removal, said upper cams are constructed and arranged to engage said lower cams in a side-by-side relation and ride upon said lower cams, thereby causing said cap to unsnap from said container, and whereby for replacing said cap on said container said upper cams are caused to ride down said lower cams and engage said lower cams in side-by-side relation thereby sealing said cap on said container.

Claim 13

The combination in accordance with claim 11 wherein the sides of said V-shaped upper and lower cams have an angular relation to one another approximating, 45°.

Claim 16

The method in accordance with claim 13 wherein said slidable plunger is constructed to be propelled in an axial direction in said container by a screw-stem which moves in cooperative relation to a screw-hole centered in said plunger, the steps which comprise; hollowing out the base of said container and the lower portion of said screw-stem to a length which extends a substantial distance beyond the inner surface of said plunger; interposing a lateral opening in the wall of said hollow lower portion of said screw-stem, said lateral opening above the inner surface of said plunger; and injecting molten product into said container in inverted position through said hollow base and said lateral opening of said screw-stem, thereby forcing said molten product into the area between the inner surfaces of said plunger and said retainer cover through said hollow base and opening.

Claim 17

The method of filling a dispenser with molten product in accordance with claim 14 wherein: said removable retainer cap may be formed with a convex upper surface thus forming the upper surface of said stick product.

Claim 18

The product by the process of claim 14.

Claim 19

The product by the process of claim 15.

Claim 20

The combination in accordance with claim 7 wherein said removable cap is in the form of an inverted cup having a depending annular skirt attached to, and sealing against said upper edge of said container by resilient snapping means comprising an annular ring disposed near the lower inner edge of said skirt, said ring constructed and arranged to engage an annular groove disposed near the upper outer edge of said container; and wherein said resilient snapping means is engaged by cam-action means comprising in combination: a plurality of V-shaped upper cams protruding from the inside wall, near the lower inner edge of said skirt; a plurality of inverted V-shaped lower cams protruding from the outside wall near the upper outer edge of said container; wherein, upon rotation of said cap relative to said container for removal, said upper cams are constructed and arranged to engage said lower cams in a side-by-side relation and ride upon said lower cams, thereby causing said cap to unsnap from said container, and whereby for replacing said cap on said container said upper cams are caused to ride down said lower cams and engage said lower cams in side-by-side relation thereby sealing said cap on said container.

Claim 21

The combination in accordance with claim 18 wherein the sides of said V-shaped upper and lower cams have an angular relation to one another, approximating 45°.
