DETAILED DESCRIPTION

[0042] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

[0043] The terms of “front”, “back”, “down”, “up”, “bottom”, “upper”, “horizontal”, “vertical”, “right”, “left” or any reference to sides or directions are used throughout the description for the sake of brevity alone and are relative terms only and not intended to require a particular component orientation.

[0044] Applicant has realized that adding a blade to the clip provides a clip which not only facilitates the opening of the bag packages, but also keeps the contents of the bag sealed after the package has been opened.

[0045] Reference is now made to FIG. 1A, which illustrates a side view of an opened cutter clip 10, constructed and operative in accordance with a preferred embodiment of the present invention, to FIG. 1B, which illustrates a user using cutter clip 10 to open a bag package 15, to FIG. 1C, which illustrates bag package 15 closed with cutter clip in a closed position and to FIG. 1D, which illustrates a side view of a closed position of the cutter clip 10.

[0046] As shown in FIG. 1A, cutter clip 10 may comprise a first arm 1, a second arm 2, an outer thick bow 13, and a blade 18. Bow 13 may be integrally connected to both first arm 1 and second arm 2 at their back ends, thereby providing a hinge between arms 1 and 2.

[0047] First arm 1 may comprise a clipping hook 4 at its front end and second arm 2 may comprise a closing hook 5 at its front end such that, to close cutter clip 10, a person may clip clipping hook 4 over closing hook 5. Closing hook 5 may hold clipping hook 4 in place while the cutter clip 10 is in a closed position, thereby preventing the opening of the cutter clip 10.

[0048] Thick bow 13 may have a thickness in the range of 0.5-5 mm, which may be thick enough to hold cutter clip 10 in a closed position and/or to minimize defects during use and manufacturing. In another embodiment, thickness in the range of 0.3-5 mm. In yet another embodiment, thickness in the range of 0.3-10 mm. Thick bow 13 may be a smooth bow or a ridged bow as shown and may provide additional flexibility to clip 10, particularly for thick bags.

[0049] In one embodiment, the cutter clip may have an integral thin hinge which connects the back ends of the first and second arms.

[0050] As mentioned hereinabove, cutter clip 10 additionally may comprise blade 18, partially shown in a close-up portion of FIG. 1A and shown in more detail in FIGS. 2A and 2B. Blade 18 may be held at an end of a long slot 17 formed in second arm 2. Long slot 17 may keep blade 18 in a protected location in cutter clip 10, to keep it from cutting fingers, slicing the package, etc.

[0051] As shown in FIG. 1B, the user may slide a closed edge 16 of package 15 through long slot 17 and against blade 18 in order to cut open package 15. Afterwards, the user may close cutter clip 10 on package 15, as shown in FIG. 1C.

[0052] FIG. 1D shows cutter clip 10 in its closed position. In this position, clipping hook 4 of first arm 1 hooks over closing hook 5 of second arm 2. Second arm 2 may press against the sides of long slot 17, pressing it closed and thus, covering blade 18 when it is not in use.

[0053] Reference is now made to FIGS. 2A and 2B which show blade station 19, blade 18 and clip 10 in an expanded view and in a combined view, respectively. As shown in FIG. 2A, blade station 19 may comprise an elevated outer wall 25, a side wall 23, a floor 21 and a flexible arm 55. During manufacturing, blade 18 may be slid onto floor 21 (FIG. 2B), under flexible arm 55 and snug up to walls 25 and 23. The blade station 19 may have a semi-circle shaped hole 61 upon which blade 18 may sit, thereby to enable blade 18 to come into contact with the bag and to leave blade 18 free for cutting.

[0054] The combination of blade 18 and blade station 19 may be placed into a wall slot 27 formed into second arm 2. Second arm 2 may also comprise sloping walls 80 which may be shaped to match flexible arm 55. Moreover, flexible arm 55 may include a protrusion 81 and sloping walls 80 may include a round slot 82 which may match protrusion 81, such that, when the combination of blade 18 and blade station 19 may be placed into wall slot 27, flexible arm 55 may bend until protrusion 81 may reach round slot 82, at which point, protrusion 81 may snap into round slot 82, thereby holding blade 18 in place.

[0055] Reference is now made to FIG. 3A which shows cutter clip 10 with blade station 18 installed therein. Side wall 25 of blade station 19 may align along the side of second arm 2. FIG. 3 also shows a cross-sectional view of second arm 2, along line AA, showing how blade 18 is held within arm 2.

[0056] It may be appreciated that a height H of the outer walls of cutter clip 10 may be large enough to hold blade station 19 therein and may also be large enough to provide strength to outer bow 13.

[0057] Reference is now made to FIG. 3B, which is a schematic illustration of an alternative embodiment of the blade-station combination. In this embodiment, blade 18 may have a hole 84 therein which may match a downward protrusion (not shown) on flexible arm 55. Thus, when blade 18 may be slid under flexible arm 55, the downward protrusion of arm 55 may snap into hole 84 of blade 18, thereby holding blade 18 to station 19.

[0058] In a further alternative embodiment, shown in FIG. 3C to which reference is now briefly made, cutter clip 10 may have a protrusion 85 formed therein near slot 17, and blade 18, with hole 84, may slide into long slot 27 and may snap onto protrusion 85.

[0059] Reference is now made to FIG. 4a, which is a schematic illustration showing some alternative locations on arms 1 and 2 for long slot 17, through which a package may be brought to blade 18. Location 34 may be on the outside of first arm 1, near clipping hook 4. Location 32 may be on the outside of the second arm 2, near closing hook 5. Location 35 may be on the outside of second arm 2, near outer bow 13. In one embodiment, long slot 17 may be located on the inner side of the first arm 1. In another embodiment, long slot 17 may be located on the outer side of the first arm 1. In yet another embodiment, long slot 17 may be located on the inner side of the second arm 2. In yet another embodiment, long slot 17 may be located on the outer side of the second arm 2. It will be appreciated that long slot 17 may be located in any suitable location on clip 10 and at any angle.

[0060] Reference is now made to FIG. 4b, which is an illustration showing another alternative location for blade 18. Location 36 may be on the outside of second arm 2. It will be appreciated that blade 18 may be located in any suitable location on clip 10 and at any angle. In this embodiment, clip 10 may be manufactured with over molding, by injecting the plastic of the clip 10 around blade 18.

[0061] In an alternative embodiment, plastic may be injected directly onto the metal of blade 18 before placing it into blade station 19. In a further alternative embodiment, clip 10 may be manufactured with over molding, by injecting the plastic of the clip 10 around blade 18. In a further alternative embodiment, blade station 19 may be over molded around blade 18.

[0062] Reference is now made to FIGS. 5A, 5B and 5C which illustrate a further alternative embodiment of the cutter clip, here labeled 10′. In this embodiment, blade 18 may be a replaceable box cutter or utility knife type of blade, labeled 18′.

[0063] FIG. 5A shows cutter clip 10′ after molding, with blade covering 30 connected, through a thin plastic connection, to second arm 2. First arm 1 may be formed with a U-shape 75 which may contribute to the flexibility of first arm 1, thereby to enable it to bend more easily around thick bags. Cutter clip 10′ may also have one or two hinges for connecting the back end of first arm 1 to the back end of second arm 2. Each hinge may be connected to the inner walls or outer walls of the first arm 1 and second arm 2 at their back ends.

[0064] FIG. 5B shows replaceable blade 18′ being placed on a floor section 32 of second arm 2, with blade covering 30 disconnected from second arm 2.

[0065] In FIG. 5C, blade covering 30 is shown placed over replaceable blade 18′, thereby holding replaceable blade 18′ within second arm 2.

[0066] It will be appreciated that both second arm 2 and blade covering 30 have long slots 17 and that these slots 17 are aligned when blade covering 30 is placed over replaceable blade 18′.

[0067] To replace blade 18′, a user may remove blade covering 30, take out the existing blade 18′ and put in a new blade 18′.

[0068] In an alternative embodiment, shown in FIG. 6 to which reference is now made, one of the arms, here labeled 40 may be formed with a large hole 50 therewithin. Large hole 50 may contribute to the flexibility of the inner wall of the arm, thereby to enable it to bend more easily around thick bags. The hole 50 may have close boundaries, as depicted in FIG. 6, or the hole 75 may have open boundaries as depicted in FIG. 5A.

[0069] In other embodiments the blade 18 may be inserted in a clip having a different design, shape or thickness. Thus, although the blade 18 has been illustrated in conjunction with a clip having a thick bow, the blade 18 may be inserted in other clip designs having different shapes and thicknesses.

[0070] In some embodiments more than the one blade may be inserted in a clip.

[0071] In one embodiment the clip may be manufactured with a cutting slot and without the blade. Hence a blade may be inserted at a later time. In this embodiment, the blade may be a utility knife type of blade, or any other type of blade.

[0072] While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
