Abstract

The present invention is a non-removable closure.

A non-removable closure in accordance with the present invention may comprise (a) a first sealant layer; (b) a sealant interface layer; and (c) a second sealant layer.

A non-refillable container for flowable materials in accordance with the present invention may comprise: (a) a cap; (b) a first sealant layer; (c) a sealant interface layer; (d) a second sealant layer; and (e) a flowable material receptacle.

A method for manufacturing a non-removable bottle closure in accordance with the present invention may comprise the steps: (a) disposing a first sealant layer on a first surface of a sealant interface layer; (b) disposing a second sealant layer on a second surface of the sealant interface layer; (c) adhering the first sealant layer to a cap; and (d) adhering the second sealant layer to a receptacle mouth.

Claims

1. A non-removable bottle closure, the closure comprising:

a first sealant layer,

a sealant interface layer; and

a second sealant layer.

2. The non-removable bottle closure of claim 1, further comprising:

a first dispensing aperture disposed within the first sealant layer;

a second dispensing aperture disposed within the sealant interface layer; and

a third dispensing aperture disposed within the second sealant layer.

3. The non-removable bottle closure of claim 2,

wherein the first, second, and third dispensing apertures are cooperatively aligned so as to provide a dispensing conduit.

4. The non-removable bottle closure of claim 1,

wherein the sealant interface layer is constructed from a material selected from the group comprising:

paper stock, metal foil and plastic.

5. The non-removable bottle closure of claim 1,

wherein the first sealant layer, second sealant layer and sealant interface layer are constructed using analogous plastics compositions.

6. The non-removable bottle closure of claim 1,

wherein at least one of the surfaces of the first sealant layer, second sealant layer and sealant interface layer is surface treated.

7. The non-removable bottle closure of claim 6,

wherein the surface treatments is selected from the group comprising:

abrading, roughening, acid etching, flame treatments, plasma treatment, thermal treatment, and primer applications.

8. An non-refillable container for flowable materials, the container comprising:

a cap;

a first sealant layer;

a sealant interface layer;

a second sealant layer; and

a flowable material receptacle.

9. The container of claim 8,

wherein the first sealant layer, sealant interface layer and second sealant layer are disposed between the cap and a receptacle mouth.

10. The container of claim 9,

wherein the first sealant layer conjoins the cap and a first surface of the sealant interface layer;

and

wherein the second sealant layer conjoins a second surface of the sealant interface layer and the receptacle mouth.

11. The container of claim 8, further comprising:

a recessed grove disposed about the interior of the cap;

a flange disposed about the exterior of the receptacle;

wherein the recessed grove disposed about the interior of the cap and the flange disposed about the exterior of the receptacle cooperate to secure the cap to the receptacle.

12. The container of claim 8, further comprising:

a recessed grove disposed about the exterior of the receptacle;

a flange disposed about the interior of the cap;

wherein the recessed grove disposed about the exterior of the receptacle and the flange disposed about the interior of the cap cooperate to secure the cap to the receptacle.

13. The container of claim 8, further comprising:

threading disposed about the cap;

threading disposed about the receptacle;

wherein the threading disposed about the cap and the threading disposed about the receptacle cooperate to secure the cap to the receptacle.

14. A method for the manufacture of a non-refillable container, the method comprising the steps:

disposing a first sealant layer to a first surface of a sealant interface layer;

disposing a second sealant layer on a second surface of the sealant interface layer;

adhering the first sealant layer to a cap; and

adhering the second sealant layer to a receptacle mouth.

15. The method of claim 14, further comprising the step:

conjoining the cap and the receptacle mouth via cooperating threading disposed on the cap and container.

16. The method of claim 14, further comprising the step:

conjoining the cap and the receptacle mouth via one or more cooperating flanges and recessed grooves.

17. The method of claim 14,

wherein the steps of adhering the first sealant layer to the cap and adhering the second sealant layer to the receptacle mouth are accomplished through induction sealing.
