Abstract

This disclosure pertains to a child deterrent closure with multiple interlocking elements on each zipper profile. The lower interlocking element of one of the profiles includes an interior flange which is unsealed thereby causing opening forces on that profile to be directed to a lower seal rather than to the lower interlocked elements. The interior flange must be moved to expose the lower interlocked elements and to direct opening forces to the lower interlocked elements.

First claim

What is claimed is:

1. A closure, reclosure or zipper, comprising:
a first profile including a first upper interlocking element and a first lower interlocking element;
a second profile including a second upper interlocking element and a second lower interlocking element configured and arranged to interlock with the respective first upper and lower interlocking elements;
the first upper interlocking element and the first lower interlocking element being located on a first base element;
the second upper interlocking element being located on a second base element, the second lower interlocking element being located on a third base element, the third base element including an upper flange element and a lower flange element, the upper flange extending to the second base element and being free of sealing to the second base element;
wherein the first base element includes a first upper flange element and a first lower flange element, the second base element includes a second upper flange element and a second lower flange element, and the upper and lower flange elements of the third base are respective third upper and lower flanges; and
wherein the third upper flange is an interior flange, and wherein the interior flange is oriented toward the first profile.

2. The closure, reclosure or zipper of claim 1 wherein the first upper and lower interlocking elements are female elements and the second upper and lower interlocking elements are male elements.

3. The closure, reclosure or zipper of claim 1 wherein the first and second profiles are comprised of polymeric material.

4. The closure, reclosure or zipper of claim 1 wherein the first upper and lower flanges are configured and arranged to be sealed or attached to a first bag wall; the second upper flange, the second lower flange and the third lower flange are configured and arranged to be sealed or attached to a second bag wall, the third upper flange is configured and arranged to be free of sealing to a first bag wall and a second bag wall.

5. The closure, reclosure or zipper of claim 4 wherein the third lower flange is configured and arranged to be attached or sealed to a second bag wall at a position below the second lower interlocking element, whereby opening forces on the second profile are directed away from the second lower interlocking element, interlocked with the first lower interlocking element, and directed toward the place of attachment of the third lower flange to a second bag wall.

6. The closure, reclosure or zipper of claim 5 , wherein opening forces can be applied to the third upper flange, thereby directing opening forces to the first and second lower interlocking elements.

7. A reclosable bag or container, comprising:
first and second bag walls, forming a storage volume therebetween and a mouth leading to the storage volume, the storage volume being made reclosable by a closure, reclosure or zipper;
the closure, reclosure or zipper including:
a first profile including a first upper interlocking element and a first lower interlocking element;
a second profile including a second upper interlocking element and a second lower interlocking element configured and arranged to interlock with the respective first upper and lower interlocking elements;
the first upper interlocking element and the first lower interlocking element being located on a first base element;
the second upper interlocking element being located on a second base element, the second lower interlocking element being located on a third base element, the third base element including an upper flange element and a lower flange element, the upper flange extending to the second base element and being free of sealing to the second base element;
wherein the first base element includes a first upper flange element and a first lower flange element, the second base element includes a second upper flange element and a second lower flange element, and the upper and lower flange elements of the third base are respective third upper and lower flanges; and
wherein the third upper flange is an interior flange, and wherein the interior flange is oriented toward the first profile.

8. The reclosable bag or container of claim 7 wherein the first upper and lower interlocking elements are female elements and the second upper and lower interlocking elements are male elements.

9. The reclosable bag or container of claim 7 wherein the first and second profiles and the first and second bag walls are comprised of polymeric material.

10. The reclosable bag or container of claim 7 wherein the first upper and lower flanges are sealed or attached to the first bag wall; the second upper flange, the second lower flange and the third lower flange sealed or attached to the second bag wall, the third upper flange is free of sealing to a first bag wall and a second bag wall.

11. The reclosable bag or container of claim 10 wherein the third lower flange is attached or sealed to the second bag wall at a position below the second lower interlocking element, whereby opening forces on the second profile are directed away from the second lower interlocking element, interlocked with the first lower interlocking element, and directed toward the place of attachment of the third lower flange to the second bag wall.

12. The reclosable bag or container of claim 11 wherein opening forces can be applied to the third upper flange, thereby directing opening forces to the first and second lower interlocking elements.
