Abstract

A dispensing package comprising one or more jackets, a screw assembly, and a movable elevator platform; the screw assembly comprising a spindle comprising two external thread portions, which allows for a quick first turn.

First claim

What is claimed is:

1. A dispensing package comprising:
a longitudinal axis;
one or more jackets, wherein the one or more jackets comprise a first end, a second end opposite the first end;
a screw assembly; and a movable elevator platform;
wherein the screw assembly comprises:
a screw base disposed adjacent to the first end and rotatably associated with the one or more jackets;
a spindle that supports external threads, wherein the spindle extends from the screw base through the first end into the one or more jackets coaxial to the longitudinal axis of the dispensing package;

wherein the spindle comprises:
a first external thread portion having a first pitch; and
a second external thread portion having a second pitch;
wherein the second pitch is larger than the first pitch;
wherein the movable elevator platform is movably engaged with the spindle of the screw assembly and comprises a coupling sleeve having an inner surface, wherein the coupling sleeve is coaxial to the longitudinal axis of the dispensing package, wherein the coupling sleeve supports internal threads that have:
a first internal thread portion having a first pitch;
a second internal non-threaded portion, wherein the second internal non-threaded portion comprises one or more cross-thread features, selected from the group consisting of a smooth surface, horizontal ribs, vertical ribs and combinations thereof;
wherein the first external thread portion of the screw assembly can engage with the first internal thread portion of the movable elevator platform along the inner surface of the movable elevator platform such that the first pitch of the first internal thread portion and the first pitch of the first external thread portion are the same;
wherein the second external thread portion of the screw assembly can cross-thread with the one or more cross-thread features of the second internal non-threaded portion of the movable elevator platform along the inner surface of the movable elevator platform.

2. The dispensing package according to claim 1 ,
wherein the first external thread portion has a major diameter;
wherein the second external thread portion has a major diameter;
wherein the major diameter of the second external thread portion is larger than the major diameter of the first external thread portion;
wherein the first internal thread portion has a major diameter;
wherein the second internal non-threaded portion has a diameter, wherein the diameter is the diameter of the coupling sleeve at the second internal non-threaded portion having no cross-thread features, wherein the diameter is equal to the major diameter;
wherein the one or more cross-thread features of the second internal non-threaded portion has a diameter which is larger than the diameter;
such that the external threads of the first external thread portion of the spindle can engage with the internal threads of the first internal thread portion of the movable elevator platform; and
such that the external threads of the second external thread portion of the spindle can cross-thread with the one or more cross-thread features of the second internal non-threaded portion along the inner surface of the movable elevator platform.

3. The dispensing package according to claim 2 , wherein the major diameter of the first external thread portion is smaller than the major diameter of the respective first internal thread portion; and the major diameter of the second external thread portion of the spindle is larger than the diameter of the second internal non-threaded portion of the coupling sleeve and smaller than the diameter of the one or more cross-thread features of the second internal non-threaded portion.

4. The dispensing package according to claim 1 ,
wherein the first external thread portion has a major diameter;
wherein the second external thread portion has a major diameter;
wherein the major diameter of the second external thread portion is larger than the major diameter of the first external thread portion;
wherein the first internal thread portion has a major diameter;
wherein the second internal non-threaded portion has a diameter wherein the diameter is the diameter of the coupling sleeve at the second internal non-threaded portion having no cross-thread features;
wherein the diameter of the second internal non-threaded portion is larger than the major diameter of the first internal thread portion;
wherein the one or more cross-thread features of the second internal non-threaded portion has a diameter which is larger than the diameter;
such that the external threads of the first external thread portion of the spindle can engage with the internal threads of the first internal thread portion of the movable elevator platform; and
such that the external threads of the second external thread portion of the spindle can cross-thread with the one or more cross-thread features of the second internal non-threaded portion of the movable elevator platform.

5. The dispensing package according to claim 4 ,
wherein the major diameter of the first external thread portion of the spindle is smaller than the major diameter of the first internal thread portion of the coupling sleeve; and
wherein the major diameter of the second external thread portion of the spindle is larger than the diameter of the second internal non-threaded portion of the coupling sleeve and smaller than the diameter of the one or more cross-thread features of the second internal non-threaded portion.

6. A dispensing package comprising:
a longitudinal axis;
one or more jackets, wherein the one or more jackets comprise a first end, a second end opposite the first end;
a screw assembly; and a movable elevator platform;
wherein the screw assembly comprises:
a screw base disposed adjacent to the first end and rotatably associated with the one or more jackets;
a spindle that supports external threads, wherein the spindle extends from the screw base through the first end into the one or more jackets coaxial to the longitudinal axis of the dispensing package;
wherein the spindle comprises:
a first external thread portion having a first pitch; and
a second external thread portion having a second pitch;
wherein the second pitch is larger than the first pitch;
wherein the movable elevator platform is movably engaged with the spindle of the screw assembly and comprises a coupling sleeve having an inner surface, wherein the coupling sleeve is coaxial to the longitudinal axis of the dispensing package, wherein the coupling sleeve supporting internal threads has:
a first internal thread portion having a first pitch;
a second internal non-threaded portion;
a third internal thread portion comprising one or a plurality of internal threads,
wherein the second internal non-threaded portion is between the first and the third internal thread portions;
wherein the first external thread portion of the screw assembly can engage with the first internal thread portion of the movable elevator platform along the inner surface of the movable elevator platform such that the first pitch of the first internal thread portion and the first pitch of the first external thread portion are the same;
wherein the second external thread portion of the screw assembly can engage with the third internal thread portion of the movable elevator platform along the inner surface of the movable elevator platform.

7. The dispensing package according to claim 6 , wherein the third internal thread portion comprises a plurality of internal threads, wherein the third internal thread portion has a second pitch, wherein the second external thread portion of the screw assembly can engage with the third internal thread portion of th
