Abstract: Disclosed herein is a method of injection molding at low, substantially constant melt pressures. Embodiments of the disclosed method now make possible a method of injection molding that is more energy—and cost—effective than conventional high-velocity injection molding processes. Embodiments of the disclosed method surprisingly allow for the filling of a mold cavity at low melt pressure without undesirable premature hardening of the thermoplastic material in the mold cavity and without the need for maintaining a constant temperature or heated mold cavity. Heretofore, it would not have been expected that a constant pressure method could be performed at low pressure without such premature hardening of the thermoplastic material when using an unheated mold cavity or cooled mold cavity.

Abstract: A low constant pressure injection molding machine forms molded parts by injecting molten thermoplastic material into a mold cavity at low constant pressures of 6,000 psi and lower. As a result, the low constant pressure injection molding machine includes a mold formed of easily machineable material that is less costly and faster to manufacture than typical injection molds.

Abstract: The present invention is directed to a container comprising a retention mechanism for attaching a closure to an opening or neck of a container with a portion of the container body comprising a physical geometry that creates more than one undercut.

Abstract: The present invention relates to an array of products comprising a plurality of different containers having a similar container to closure interface across at least one brand and different volumetric sizes wherein at least one of said containers comprises more than one undercut and comprising a plurality of different closures comprising at least one common component.

Abstract: The present invention is directed to a process for the manufacture of a blow molded container comprising a physical geometry that creates more than one undercut and a means for removal of said container from a mold used to form said container.

Abstract: A tampon applicator is disclosed which has an insertion tip for facilitating insertion of a tampon into a woman's vagina. The tampon applicator includes a hollow first member capable of housing a tampon. The first member has a central longitudinal axis and first and second ends. An insertion tip is located on the first end of the first member and extends outwardly therefrom. The insertion tip contains an aperture that extends therethrough. The insertion tip contains a plurality of corrugations capable of expanding radially outwardly as the tampon is expelled from the first member. The tampon applicator is also disclosed in combination with a tampon.
