Abstract

A container-closure system that comprises a container ( 1 ) without screw threads; a custom wiper ( 3 ) that sits in the neck of the container; a magnetic ring ( 2 ) that encircles the neck of the container; a custom closure ( 5 ) that comprises a handle ( 5 b ), a conic section ( 5 g ), a wand ( 5 d ) and an application surface ( 4 ) that depends from the distal end of the wand; an overshell ( 8 ) that fits over the handle and supports a metal ring ( 6 ). The strength of the magnetic ring for the metal ring is sufficient to effect a tight seal in two sealing zones: between the conic section ( 5 g ) of the closure and the beveled surface ( 3 g ) of the wiper ( 3 ); and between the bottom ( 5 a ) of the handle and the custom sealing lip ( 3 a ) on the top of the wiper.

First claim

What is claimed is:

1. A magnetic container-closure system that comprises:
a container ( 1 ) that has:
a shoulder ( 1 d ) that supports a neck ( 1 b ), the neck having a landing area ( 1 f );
an internal reservoir ( 1 a ) that is suitable for holding a product which may be accessed through an opening ( 1 e ) in the neck of the container;
a wiper ( 3 ) located in an opening ( 1 e ) of the neck ( 1 b ) and comprising a lower opening ( 3 d ) and an upper opening ( 3 e ) that is surrounded by a beveled surface ( 3 g ) and a sealing lip ( 3 a ) that extends upwardly and outwardly from the beveled surface; and
one or more magnetic elements ( 2 ) attached to the neck ( 1 b );

a closure ( 5 ) that comprises:
an overshell ( 8 );
a handle ( 5 b ) that is secured into the overshell;
a conic section ( 5 g ) that depends from the handle;
a wand ( 5 d ) that depends from the conic section and that supports an application surface ( 4 ) on its distal end;
one or more ferromagnetic elements secured in the overshell;

such that, when the closure ( 5 ) is fully seated on the container ( 1 ), the attraction of the magnetic elements ( 2 ) of the container for the ferromagnetic elements ( 6 ) of the closure causes the compression of the sealing lip ( 3 a ) by the bottom ( 5 a ) of the handle, and compression of the beveled surface ( 3 g ) by the conic section ( 5 g ).

2. The magnetic container-closure system of claim 1 wherein the container ( 1 ) does not have screw threads.

3. The magnetic container-closure system of claim 2 wherein the one or more magnetic elements ( 2 ) is implemented as a magnetic ring placed over the neck ( 1 b ) of the container ( 1 ), such that the top of the magnetic ring is higher than the landing area ( 1 f ) of the neck, and the one or more ferromagnetic elements ( 6 ) is fashioned as a steel ring.

4. The magnetic container-closure system of claim 3 wherein when the closure ( 5 ) is fully seated on the container ( 1 ), then the steel ring ( 6 ) contacts the magnetic ring ( 2 ) before the overshell ( 8 ) bottoms out on the shoulder ( 1 d ) of the container.

5. The magnetic container-closure system of claim 3 wherein the magnetic ring ( 2 ) has a maximum energy product in the range of 10 to about 100 MGOe.

6. The magnetic container-closure system of claim 5 wherein the magnetic ring ( 2 ) has a maximum energy product in the range of 25 to about 75 MGOe.

7. The magnetic container-closure system of claim 6 wherein the magnetic ring ( 2 ) has a maximum energy product in the range of 40 to about 50 MGOe.

8. The magnetic container-closure system of claim 7 wherein the magnetic ring ( 2 ) is NdFeB (neodymium-iron-boron) having magnetization grade of N45.

9. The magnetic container-closure system of claim 1 wherein the beveled surface ( 3 g ) and the sealing lip ( 3 a ) are molded from a thermoplastic elastomer having a Shore hardness of less than 50.

10. The magnetic container-closure system of claim 1 wherein the application surface ( 4 ) is fashioned as a fiber brush.

11. The magnetic container-closure system of claim 1 wherein the wand ( 5 d ), the conic section ( 5 g ) and the handle ( 5 b ) are molded as one piece.
