Beschreibung[en]
Background

The present invention relates to a multi-part closure device such as an ice pack clip for releasably sealing ice packs and similar flexible open-ended containers.

It is known to seal ice packs used for a variety of purposes with ice pack clips which are generally of the blade and trough (or sheath) type. The known devices generally include a hinge at one end connecting the blade and the trough and a latch at the other end for releasably closing the clip to seal a bag which passes between the trough and the blade when the clip is closed. Similar clips or clamps are also suitable for a variety of other purposes, including ostomy bags, umbilical cord clamps, etc.

Depending upon the type of clip or clamp chosen, there are shortcomings. For instance, some clips presently used with ice packs consist of a one-piece construction having a blade portion and a trough portion pivotally connected by a hinge. This construction is not easily adapted to automated sorting and feeding. Due to the inherent flexibility of the hinge, the blade and trough move with respect to one another when the clip is subjected to the vibrations often encountered during automated mechanical sorting processes. This movement makes automated feeding difficult. As a result, currently it is required that these clips be attached to ice packs manually resulting in limited production capacity and requiring human participation in the assembly process.

As such, there exists a need for a clip suitable for use on ice packs, ostomy bags, umbilical cord clamps, etc. that exhibits all the advantages of the presently used clip but lends itself to automated sorting, feeding, and assembly.

JP 10 236487 A discloses a closure device comprising clip components fastened to a separate holder. US 5,050,272 discloses a closure device with a blade and a sheath as clip components with the connector ends of the clip components fastened one to the other. US 4,416,038 discloses a balloon clip for the tubular stem of a balloon. The clip components are fastened to a hinge portion. US 5,604,959 discloses an ice pack clip having a blade, a trough, a hinge and a latch.

Summary of the Invention

The present invention discloses a multi-part closure device having a first and a second clip body component each having a connecting portion. A flexible neck is disposed upon at least one of the clip body components proximate to the connecting portion. The flexible neck forms a hinge between the first and second clip body components when the first and second connecting portions are secured one to the other. The first and second connecting portions serve to rigidly connect the two clip body components one to the other at a rigid connection while allowing each clip body component having a flexible neck disposed thereon to move with respect to the other clip body component and the rigid connection.

Description of the Invention

The present invention and its advantages are best understood by referring to the drawings, like numerals being used for like and corresponding parts of the various drawings.

Prior art FIGS. 1 and 2 show a clip 10 which in pertinent part is formed of four major components, a substantially planar blade 12, a trough 14, a hinge 16, and a latching mechanism 18. The blade 12 is designed to fit within the trough 14 such that when a bag (not shown) is interposed between the closed blade 12 and the trough 14, the blade 12 and trough 14 cooperate to effectively seal the bag. The blade 12 and trough 14 are designed to be manufactured as a single unit and remain connected via the hinge 16. The hinge commonly used is preferably a strap-like hinge, known in the art as a "living hinge". The present invention eliminates this living hinge 16 and substitutes a new configuration.

In the present invention, shown in FIG. 3, a new clip 20 is depicted. The clip 20 is manufactured as two separate components or clip body components 22 and 24. The clip body components 22 and 24 may be configured similarly to the trough and hinge arrangement disclosed in US Patent 5,604,959 . However, in the present invention, it is not until the two portions 22, 24 are attached one to the other, that the clip 20 itself is ultimately formed.

Looking to FIG. 3, it can be seen that each clip body component 22, 24 is provided with a portion of a latch or latching mechanism 26 and a blade connector end, also referred to as a connecting end, or connecting portion 28. The specific design of the latching mechanism 26 is not critical to the invention and therefore the mechanism 26 may be configured similar to that disclosed in US Patent 5,604,959 .

Proximate to the connecting portion 28 of at least one of the clip body components 22, 24 is a necked portion or necked region 30. The necked region 30 is sufficiently thin and flexible enough to enable the clip body component 22 or 24 upon which it is located to hinge at the necked region 30 once the clip 20 is assembled. As shown in FIG. 3, this necked region 30 effectively allows the clip 20 to open and close enabling movement between a latched and an unlatched position. Formation of the clip 20 is accomplished when the connecting portions 28 of each clip body component 22 and 24 are fastened in some manner to one another resulting in the creation of a rigid configuration or connection 32.

To better enable the necked region 30 to hinge properly at the rigid connection 32, the components 22 and 24 may be constructed so as to possess added thickness and rigidity at the connecting portions 28. Further, the necked region 30 may be made sufficiently thin so as to flexibly hinge between the connecting portion 28 and the remainder of the clip body component 22 and/or 24. This arrangement moves the latching mechanism 28 toward and away from a clip open and a clip closed position allowing a bag (not shown) to be captured between the clip body components 22 and 24.

More specifically, the necked region 30 permits the clip body component 22 having the necked region to hinge with respect to the other clip body component and the rigid connection 32. Although the necked region 30 is depicted as being on clip body component 22, it may alternatively be located on clip body component 24. Other embodiments, not shown, may include providing at least one necked region 30 on each clip body component 22 and 24. This would enable both clip body components 22 and 24 to hinge with respect to each other while the rigid connection 32 remained stationary.

A number of possible alternatives are available to fasten the clip body components 22 and 24 together. In the FIG. 4 embodiment, two surfaces, 34 and 36 are depicted, one at each of the connecting portions 28. These surfaces when joined together form the rigid connection 32. The rigid connection 32 can be made permanent via the application of adhesives, through the use of thermal and/or ultrasonic bonding, etc. It is well known in the art that a typical bond may be configured so as to include raised features (not shown) in order to create a bond concentration. Alignment nibs 38 depicted in the FIG. 4 may also be provided on either or both connecting portions 28 to assist in alignment of the clip body components 22, 24. Alignment nibs 38 may take any number of forms including raised areas and complementary recessed areas and be located on either or both of the surfaces 34 and/or 36.

One possible alternative, as shown for example in FIG. 5, provides fasteners 40 which serve to fasten the clip body components 22 and 24 one to the other. Examples of such fasteners 40 may include bayonet-type fasteners as shown having a male portion 42 and a female portion 44, however, post and post aperture arrangements, single and multiple tab and slot arrangements, as well as other male/female type fittings are suitable as well. In general, it is desirable to design the fasteners 40 so that more force is required to separate the connecting portions 28 than is required to unlatch the latch mechanism 26. As such, in some embodiments, the fasteners 40 may be semi-permanently joined. In other embodiments, the fasteners 40 may be permanently joined. Likewise, it should be apparent that it is also desirable to design the fasteners 40 to have sufficient strength to entrap and seal a bag or other material, such as an ice pack, between the body components 22 and 24 so that the material does not leak fluid therefrom.

Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions, and alterations can be made therein without departing from the scope of the invention as defined by the appended claims.
