Abstract

An improved reusable fastener for closing flexible bags and the like. The fastener utilizes a conventional twist tie or the like adhered to a piece of tape having a pressure-sensitive adhering surface. The twist tie has two non-metallic sides, with a small diameter wire laminated or bonded therebetween. The width of the tie is less than the width of the tape, thereby leaving a portion of the pressure-sensitive adhering surface exposed. To use the fastener, the user closes the throat of the bag and places the fastener around the throat. The user presses the fastener together, resulting in the pressure-sensitive surface on the tape adhering to itself as the wire deforms. This keeps the throat of the bag closed. The bag will remain closed until the user pulls the ends of the tape apart. No twisting or untwisting of the ends of the twist tie is necessary.

Claims

1. An improved fastener for closing the open end of a flexible container comprising the combination of:

a piece of tape having a pressure-sensitive adhering surface on a first side;

a strip of deformable material, wherein the length of the strip of deformable material is greater than the length of the piece of tape;

means for attaching the strip of deformable material to the pressure-sensitive adhering surface of the piece of tape wherein the width of the strip of deformable material is less than the width of the piece of tape thereby leaving an exposed portion of the pressure-sensitive adhering surface, wherein the strip of deformable material is deformed around the neck of the container and the pressure-sensitive adhering surface is pressed against itself at the exposed portion in order to close the container.

2. The fastener of claim 1 also comprising first and second reinforcing end strips of tape placed over first and second portions of the strip of deformable material and means for attaching the reinforcing end strips to the exposed portion of the pressure sensitive adhering surface at first and second ends of the piece of tape.

3. The fastener of claim 1 wherein the strip of deformable material comprises

a first non-metallic strip;

a second non-metallic strip; and

a small diameter wire secured between the first and second non-metallic strips.

4. The fastener of claim 3 also including means for adhering the small diameter wire to the first non-metallic strip, means for adhering the small diameter wire to the second non-metallic strip, wherein the first non-metallic strip adheres more strongly to an adhesive than does the second non-metallic strip.

5. The fastener of claim 1 wherein the pressure-sensitive adhering surface on the first side of the piece of tape is an adhesive coating.

6. The fastener of claim 1 also including a piece of backing tape attached to a second side of the piece of tape.

7. The fastener of claim 1 wherein the strip of deformable material will not spring back of its own accord to its original shape after it is deformed around the neck of the container.

8. An improved fastener for closing the open end of a flexible container comprising the combination of:

a piece of tape having a pressure-sensitive adhering surface on a first side;

a strip of deformable material;

means for attaching the strip of deformable material to the pressure-sensitive adhering surface of the piece of tape wherein the width of the strip of deformable material is less than the width of the piece of tape, thereby leaving an exposed portion of the pressure-sensitive adhering surface wherein the strip of deformable material is deformed around the neck of the container and the pressure-sensitive adhering surface is pressed against itself at the exposed portion in order to close the container and wherein the length of the strip of deformable material is less than the length o the piece of tape and first and second ends of the piece of tape are folded over respective first and second ends of the strip of deformable material and attached to the exposed portion of the pressure-sensitive adhering surface of the piece of tape so as to provide tabs at the ends of the fastener.

9. An improved fastener for closing the opening end of a flexible container comprising a strip of deformable material having a first non-metallic strip, a second non-metallic strip, and at least one small diameter wire laminated between respective inside surfaces of the first and second nonmetallic strips, the improvement comprising a pressure-sensitive adhering surface on a portion of an outside surface of the first non-metallic strip intermediate the ends of the first non-metallic strip, wherein the pressure-sensitive adhering surface does not extend the entire length of the first non-metallic strip and wherein the wire is deformed around the neck of the container and the pressure-sensitive adhering surface is pressed against itself in order to close the container.

10. An improved fastener for closing the open end of a flexible container comprising the combination of:

a piece of tape having a pressure-sensitive adhering surface on a first side;

a strip of deformable material;

means for attaching the strip of deformable material to the pressure-sensitive adhering surface of the piece of tape wherein the width of the strip of deformable material is less than the width of the piece of tape thereby leaving an exposed portion of the pressure-sensitive adhering surface;

a first non-adhering end tab at a first end of the fastener;

a second non-adhering end tab at a second end of the fastener, wherein the strip of deformable material is deformed around the neck of the container and the pressure-sensitive adhering surface is pressed against itself at the exposed portion in order to close the container.
