Abstract

A self-closing bag holder for a flexible bag. The bag bolder has a pair of resilient arms for supporting the bag and a pair of resilient handles. Each arm is joined with a handle by a rocker, which provides a fixed angle between the arm and the handle. The other ends of the arms are releasably hinged together. The other ends of the handles are joined together such that they bow away from each other because of the fixed angle rockers. The rockers are pivotally joined together, such that upon compressing the handles, the rockers will pivot to cause the arms to expand and bow away from each other, thus opening the flexible bag. Upon release of the handles, the arms will retract toward each other, thus closing the bag, while the handle will regain its originally bowed shape. The self-closing feature of the bag holder allows an operator to open and close the bag without having to touch the bag itself. Also, when no pressure is exerted on the handles, the arms and thus the bag will remain closed.

Claims

1. A self-closing bag holder, comprising:

a first resilient arm having afar end and a near end, said far end having a first hinge part;

a second resilient arm having a far and a near end, said far end having a second hinge part, said first and second hinge parts being adapted to be releasably engaged;

a first resilient handle having afar end and a near end;

a second resilient handle having a far end and a near end;

a first rocker, having a base, adapted to join between said near end of said first arm and said near end of said first handle, defining a substantially fixed angle;

a second rocker, having a base, adapted to join between said near end of second arm and said near end of said second handle, defining a substantially fixed angle, wherein said first and second resilient handles are joined together at their far ends such that the resilient handles bow away from each other, wherein said pivoting bases of said first and second rockers are adapted to be pivotally engaged,

such that upon compressing said first and second handles, said first and second resilient arms bow outwardly with respect to each other to an open position, and upon release, said resilient arms retract toward each other to a closed position.

2. The self-closing bag holder of claim 1, wherein said first and second arms comprise complementary locking means to maintain closure when said first and second resilient arms are closed.

3. The self-closing bag holder of claim 1, wherein the center of said first hinge part on said first resilient arm is aligned with said first arm, and the center of said hinge part on said second resilient arm is aligned with said second arm.

4. The self-closing bag holder of claim 1, wherein each of said first and second arms further comprises a lock thereon to prevent a bag from sliding on said arms.

21. The bag holder of claim 1, wherein said first and second resilient arms have a thickness that tapers from said near ends down towards said far ends.

5. A self-closing bag holder assembly, comprising:

a holder, comprising;

a first resilient arm having a far end and a near end, said far end forming a pair of hinge ears;

a second resilient arm having a far end and a near end, said far end forming a hinge tab, said hinge tab being adapted to be releasably engaged between said hinge ears;

a first resilient handle having a far end and a near end;

a second resilient handle having a far end and a near end, said far ends of said first and second handles being adapted to be joined together;

a first rocker, having a pivoting base, adapted to join between said near end of said first resilient arm and said near end of said first resilient handle;

a second rocker, having a pivoting base, adapted to join between said near end of second resilient arm and said near end of said second resilient handle, said pivoting bases of said first and second rockers adapted to be pivotally engaged such that first and resilient handles defining an angle greater than an angle defined by said first and second resilient arms, such that upon compressing said first and second handles, said first and second resilient arms bow outwardly with respect to each other to an open position, and upon release, said resilient arms retract toward each other to a closed position;

a flexible bag, having a rim with openings to be slide onto said first and second resilient arms of said holder.

6. The bag holder assembly of claim 5, wherein said holder is mounted on top of the rim of a container.

7. The bag holder assembly of claim 5, wherein said holder is mounted on a vertical surface.

8. A self-closing bag holder, comprising:

a first resilient member having long and short segments;

a second resilient member having long and short segments;

a first rocker joining said long and short segments of said first resilient member and forming a predetermined angle between said segments;

a second rocker joining said long and short segment of said second resilient member and forming a predetermined angel between said segments;

wherein said first and second rockers are coupled at a common pivot point;

wherein said short segments of said first and second members are coupled together and bowed outwardly away from each other, defining a handle;

wherein said long segments of said first and second members are releasably coupled together;

wherein said long segments of said first and second members are adapted to be extendable outwardly to an open position from each other upon squeezing of said handle, and retractable inwardly to a closed position upon release of said handle.

9. The bag holder of claim 8, wherein said short segments are coupled by a hinge.

10. The bag holder of claim 8, wherein said long segments of said first and second members are releasably coupled by a hinge, said hinge comprising ear and tab portion, said ear portion being integrally formed on said long segment of said first member and said tab portion being integrally formed on said long segment of said second member.

11. The bag holder of claim 8, further comprising:

locking means to releasably engage the rim of a bag to said members.

12. The bag bolder of claim 8, wherein said pivots of said first and second members are pivotally engaged with a hinge.

13. The bag holder of claim 8, further comprising a bag having a rim supported by said long segments of said first and second segments.

14. A self-closing bag holder, comprising:

a first elongated resilient member having a long segment, a short segment, and a first rocker, said first rocker adapted to join said long and short segments of said first member to define a substantially fixed angle between 90 and 180 degrees;

a second elongated resilient member having a long segment, a short segment and a second rocker, said second rocker adapted to join said long and short segments of said second member to define a substantially fixed angle between 90 and 180 degrees;

means for pivotally engaging said first and second rockers;

means for joining the ends of said short segments;

wherein the joined short segments are bowed away from each other,

wherein the joined long segments are bowed away from each other upon compression of said short segments by a user and

wherein the joined long segments are retracted toward each other upon release of said short segments by the user.

15. The self-closing bag holder of claim 14, wherein said ends of said long segments are joined together by a releasable hinge.

16. The self-closing bag holder of claim 14, further comprising:

means for latching said long segments together when they are closed.

17. The self-closing bag holder of claim 16, further comprising:

means for keeping the bag on said long segments from sliding.

18. The self-closing bag holder of claim 17, wherein said means for joining the ends of said short segments is a thin connector integrally formed with said short segments.
