Abstract

There is a dispensing container. The dispensing container has a head, a body, and a closure. The head has a neck and a shoulder. The neck also has a bore extending longitudinally therethrough. The neck defines one or more external threads. The head has an indentation extending therein and circumferentially therearound proximal to the junction of the neck and the shoulder. The indentation is bounded by a tapered surface tapering outward with respect to the neck towards a top surface of the shoulder. The body is connected to the shoulder. The body has a chamber therein adapted to retain a product. The bore is in communication with the chamber. The closure defines one or more internal threads therein. The one or more internal threads are intermated with the one or more external threads. The closure has a skirt having a leading edge. The indentation in the head receives the leading edge. The leading edge contacts the tapered surface. The closure is openable and reclosable with respect to the head. The head and the closure are adapted such that the leading edge returns to contact with the tapered surface upon reclosure by the closure.

Claims

1. A dispensing container, comprising:

a head, the head having a neck and a shoulder, the neck having a bore extending longitudinally therethrough, the neck defining one or more external threads, the head having an indentation extending therein and circumferentially therearound proximal to the junction of the neck and the shoulder;

the indentation in the head being bounded by a tapered surface tapering outward with respect to the neck towards a top surface of the shoulder,

a body connected to the shoulder, the body having a chamber therein adapted to retain a product, the bore being in communication with the chamber; and

a closure defining one or more internal threads therein, the internal threads being intermated with the external threads, the closure having a skirt, the skirt having a leading edge, the indentation in the head receiving the leading edge, the leading edge contacting the tapered surface, the closure being openable and reclosable with respect to the head, the head and the closure being adapted such that the leading edge returns to contact with the tapered surface upon reclosure by the closure.

2. The dispensing container of claim 1, wherein the dispensing container is plastic, and wherein the body takes the form of a tube, the tube being connected to the head at an end thereof.

3. The dispensing container of claim 1, wherein the skirt defines an inner skirt and an outer skirt, and wherein the inner skirt has the leading edge.

4. The dispensing container of claim 2, wherein the chamber has product therein, and wherein the tube is sealed at an end opposite the end connected to the head.

5. The dispensing container of claim 1, wherein the indentation in the head is bounded by a inner surface that is generally directional with respect to the neck and extends circumferentially around the neck, and wherein the indentation is bounded by a bottom surface that generally perpendicularly intersects the inner surface and extends outward with respect to the neck, the bottom surface intersecting the tapered surface.

6. The dispensing container of claim 1, wherein the tapered surface is substantially planar.

7. The dispensing container of claim 1, wherein the tapered surface is curved.

8. The dispensing container of claim 2, wherein the indentation in the head is bounded by a inner surface that is generally directional with respect to the neck and extends circumferentially around the neck, and wherein the indentation is bounded by a bottom surface that generally perpendicularly intersects the inner surface and extends outward with respect to the neck, the bottom surface intersecting the tapered surface, the closure having an inner skirt and an outer skirt, and the inner skirt having the leading edge.

9. The dispensing container of claim 8, wherein the tapered surface is substantially planar.

10. The dispensing container of claim 6, wherein the tapered surface is inclined at an angle of about 20°

to about 70°

with respect to a line perpendicular to the longitudinal extension of the neck.

11. The dispensing container of claim 6, wherein the tapered surface is inclined at an angle of about 30°

to about 45°

with respect to a line perpendicular to the longitudinal extension of the neck.

12. The dispensing container of claim 2, wherein the head and the tube have a diameter of about 10 mm to about 25 mm.

13. A dispensing container, comprising:

a head, the head having a neck and a shoulder, the neck having a bore extending longitudinally therethrough, the neck defining one or more external threads, the head having a tapered surface extending circumferentially therearound proximal to the junction of the neck and the shoulder;

the tapered surface tapering outward with respect to the neck,

a body connected to the shoulder, the body having a chamber therein adapted to retain a product, the bore being in communication with the chamber; and

a closure defining one or more internal threads therein, the internal threads being intermated with the external threads, the closure having a skirt, the skirt having a leading edge, the indentation in the head receiving the leading edge, the leading edge contacting the tapered surface, the closure being openable and reclosable with respect to the head, the head and the closure being adapted such that the leading edge returns to contact with the tapered surface upon reclosure by the closure.

14. The dispensing container of claim 13, wherein the dispensing container is plastic, and wherein the body takes the form of a tube, the tube being connected to the head at an end thereof.

15. The dispensing container of claim 14, wherein the skirt defines an inner skirt and an outer skirt, and wherein the inner skirt has the leading edge.

16. The dispensing container of claim 15, wherein the tapered surface is substantially planar.

17. The dispensing container of claim 16, wherein the tapered surface is inclined at an angle of about 20°

to about 70°

with respect to a line perpendicular to the longitudinal extension of the neck.
