Abstract
A bag closure clip including a pair of opposing T-shaped clip members held in pivotal engagement by a U-shaped metal spring. Each clip member includes a jaw, a handle, and a fulcrum. As the handles are squeezed toward each other, the jaws open to allow a bag, such as for snack food or cereal, to be inserted between the jaws. When the handles are released, the spring forces the jaws towards each other to grip the bag and hold it closed. The U-shaped spring is fitted over the fulcrum and is confined to the space between the clip members so that the outwardly facing surfaces of the clip members are substantially uninterrupted.
Claims18
A bag closure clip comprising:
- first and second essentially identical opposing T-shaped clip members, each clip member including a jaw, a handle extending from the jaw, and a substantially uninterrupted front surface extending along the jaw and handle;
- each handle having first and second risers extending from the handle to terminate in slots, the slot of the first riser having a 90 degree orientation relative to the slot of the second riser, the first and second risers of the first clip member hingedly engaging the second and first risers of the second clip member, respectively, to form a pair of fulcrums;
- and
- a U-shaped metal clip spring having a pair of side webs connected by a central web, each of the side webs attaching to a corresponding clip member to hold the first and second risers of the opposing clip members in pivotal engagement, the clip spring being biased to close the jaws, the central web of the clip spring being positioned beyond the pair of fulcrums, and the side webs extending within the jaws.

A bag closure clip comprising:
- a pair of clip members each including a jaw and a handle, each of said clip members further including a front surface extending along said jaw and said handle;
- fulcrum means for hingedly supporting said clip members relative one another with said jaws facing one another, with said handles facing one another, and with said front surfaces facing outwardly away from one another to define the lateral extent of the clip;
- spring support means on each of said clip members for supporting a spring, said spring support means being located toward said jaws from said fulcrum means;
- and
- a U-shaped spring fitted over said fulcrum means and bearing against both of said spring support means on each of said clip members to urge said jaws toward one another, said fulcrum means, said spring support means, and said spring being located between said front surfaces of said clip members, wherein said front surfaces are substantially uninterrupted.

- a pair of clip members each including a jaw and a handle, each of said clip members further including a front surface extending along said jaw and said handle;
- fulcrum means for hingedly supporting said clip members relative one another with said jaws facing one another, with said handles facing one another, and with said front surfaces facing outwardly away from one another to define the lateral extent of the clip, wherein the fulcrum means comprises a riser extending from each handle to terminate in a slot, the slot of the riser of one clip member hingedly engaging the slot of the riser of the other clip member;
- spring support means on each of said clip members for supporting a spring, said spring support means being located toward said jaws from said fulcrum means;
- and
- a U-shaped spring fitted over said fulcrum means and bearing against both of said spring support means on each of said clip members to urge said jaws toward one another, said fulcrum means, said spring support means, and said spring being located between said front surfaces of said clip members, whereby said front surfaces are substantially uninterrupted.

A bag closure clip comprising:
- a pair of clip members each including a jaw and a handle, each of said clip members further including a front surface extending along said jaw and said handle, wherein the pair of clip members are essentially identical, whereby the pair of clip members can be formed from one mold;
- fulcrum means for hingedly supporting said clip members relative one another with said jaws facing one another, with said handles facing one another and with said front surfaces facing outwardly away from one another to define the lateral extent of the clip, wherein the fulcrum means comprises first and second risers extending from each handle to terminate in slots, the slot of the first riser having a 90 degree orientation relative to the slot of the second riser, the first and second risers of one clip member hingedly engaging the second and first risers of the other clip member, respectively;
- spring support means on each of said clip members for supporting a spring, said spring support means being located toward said jaws from said fulcrum means;
- and
- a U-shaped spring fitted over said fulcrum means and bearing against both of said spring support means on each of said clip members to urge said jaws toward one another, said fulcrum means, said spring support means, and said spring being located between said front surfaces of said clip members, whereby said front surfaces are substantially uninterrupted.

An improved bag closure clip including a pair of hinged clip members, each of said clip members having a jaw and a handle, said clip members including a fulcrum about which said clip members hinge, and a spring mechanism for urging the jaws toward one another, wherein the improvement comprises:
- said spring mechanism comprising:
- a spring support element on each of said clip members, said spring support elements located between said fulcrum and said jaws and extending within said jaws;
- and
- a U-shaped spring extending over said fulcrum and within said jaws and engaging both of said spring support elements;
- and
- said clip members including a substantially uninterrupted exterior surface extending along each of said handles and jaws said exterior surfaces of said clip members facing away from one another, said spring positioned between said external surfaces.
3 more elements
A bag closure clip comprising:
- a pair of opposing T-shaped clip members, each clip member having a jaw and a handle extending from the jaw, wherein each clip member includes a substantially uninterrupted external surface extending along the jaw and handle,said external surfaces of said clip members facing away from one another;
- fulcrum means contained in the clip members;
- and
- a clip spring attached to the clip members and extending within the jaws of the clip members to hold the fulcrum means in pivotal engagement, the clip spring being biased to close the jaws when no force is applied to the handles, said clip spring located between said external surfaces.
