Definitions

  • This invention relates to the field of enclosing material in packaging material, such as in netting, bags, or casing. More particularly, the invention relates to the field of enclosing edible food products, such as hams, poultry, sausages, and cheeses, in packaging material, such as in netting or casing. More particularly, this invention relates to the field of enclosing material such as edible food products in packaging material such as tubular netting and closing the ends of the netting with a clip.
  • Various materials are commonly packaged in netting, including edible food products.
  • Whole chickens, for example, are commonly sold enclosed in a clear plastic bag, which is sealed by a clip. Sausages are created by extruding a pasty mixture of chopped meats and spices into a tubular casing, which is sealed at either end by a clip.
  • Some items such as fruit and potatoes are packaged in nets in order to sell the items in lots, such as by the dozen or by weight.
  • These types of items are often placed in bag-type nets, the top of the bag is gathered, and a clip is applied to close the bag.
  • a label may also be placed at the neck of the gathered bag to be clipped to the bag, with identifying information such as the provenance, weight, lot number, or expiration date of the items.
  • a loop is formed in the netting to create a handle on the package, to ease handling of the items, which may be heavy, and to allow consumers to lift the items without actually touching the items.
  • a label may be attached to one of the clips to provide identifying information.
  • items are packaged in netting in order to enhance the appearance of the items after processing.
  • sausages, hams, and cheeses are often encased in tubular netting, as described above, prior to processing.
  • the item expands within the netting and pushes through the mesh of the netting.
  • the netting is removed and discarded.
  • the item retains a dimpled appearance that is considered pleasing to consumers.
  • the bag, the casing, and the netting must be closed and a clip is the commonly-accepted means for closing food packaging material, whether it is a bag, a net, or a casing. Manual and automated clippers are commercially available.
  • the clips for a clipper generally are supplied on either a reel or in stick fonn. Clips can be made of metal or plastic. They are formed in an upside-down U shape, similar to a common office staple. A prior-art metal clip is described in, for example, United States
  • Patent No. 6,401 ,306 to Hanten et al. which is assigned to the assignee of the present application and the disclosure of which is incorporated by reference.
  • FIG. 1 An exemplary prior art clip is illustrated in FIG. 1.

  • the clips 20 are held together by a variety of ways, such as glue, tape, plastic guides, or other means, none of which are within the purview of the present invention.
  • the cartridge 30 is inserted in a clipper 32 and moves along a rail 34, as shown in FIG. 3. Additionally, a guide rail 36 on top of the cartridge 30 holds the clips 20 to the rail 34. It is important to maintain the clips 20 on the rail 34.
  • the first clip 2OA of a cartridge 30, consisting of clips 2OA, 2OB, 20C 3 etc., must be precisely located over a die and under a punch in order to securely fasten the neck of the netting.
  • Maintaining registry of the clips 20 on the rail 34 within the clipper 32 is important to precise control of the clipper 32. Maintaining fast movement of the clips 20 along the rail 34 is also important, especially for high-speed automated manufacturing processes. Accordingly, maintaining registry of the clips and keeping the cartridge moving has been a problem for clipper manufacturers.
  • the netting is gathered into a neck that will fit within the space 38 defined by the legs 24, 26 and the inside face 40 of the top section 22.

  • the clip 102 of one embodiment of the present invention is shown in cross section in FIG. 5.
  • Clip 102 preferably made of a malleable metal, has a top section 104 with an internal face 106 and an external face 108. As illustrated in FIG.
  • top section 104 is generally rounded, but it can be straight and can have sharp comers if desired.
  • Two legs 110, 1 12 extend from opposite ends of top section 104. Accordingly, legs 110, 112 and top section 104 define an open space 118 within clip 102.
  • Top section 104 preferably has an indentation 114, as shown in cross section in FIG. 5 and in plan view in FIG. 6.
  • the indentation 1 14 is provided at generally the midpoint of top section 104, between legs 110, 112, and is preferably approximately V-shaped in cross section.
  • the position of indentation 114 between legs 110, 112 can be closer to one leg or to another, however.
  • an approximately V-shaped indentation 114 is preferable, as it is easier to manufacture, other shapes can be used, such as hemispherical or liemi-oval, or rectangular, square, or any higher-order polygon.
  • a pin 1 16 protrudes from the internal face 106 of top section 104, into space 118.
  • Pin 116 preferably corresponds in location, orientation, and cross-sectional shape to indentation 114. Accordingly, pin 1 16 is preferably located at generally the midpoint of top section 104, between legs 1 10, 112, and is approximately V-shaped. The position of pin 116 between legs 110, 1 12 can be closer to one leg or to another, however, and need not be directly below indentation 114. Furthermore, while an approximately V-shaped pin 116 is preferable, as it is easier to machine, other shapes can be used, such as hemispherical or hemi-oval, or rectangular, square, or any higher-order polygon.
  • both indentation 114 and pin 116 are formed during manufacture by placing clip 102 over an anvil having a groove corresponding to pin 116, and pounding on external face 108 with a hammer having an extrusion corresponding to indentation 114. The hammer will then form indentation 114 in external face 108 and the pressure of the hammer will force the metal of clip 102 into the groove of the anvil, forming pin 116.
  • Other methods of creating indentation 114 and pin 1 16 will suffice, such as forging techniques, injection molding, or casting, depending on the material of the clip 102, which can he metal, plastic, or other.
  • a plurality of clips 102 are joined together to form a cartridge of clips 102.
  • Suitable means to join clips 102 to form a cartridge include glue or tape.
  • the cartridge is loaded into a clipper 124 in a conventional manner.
  • Clipper 124 can be any conventional clipper, modified, however, as described herein.
  • Clipper 124 is preferably a manual clipper, such as a Model EZ 4212 sold by Poly-clip System Corp., or a single or double automated clipper, such as a Model TCSA 65 sold by Poly-clip System Corp.
  • the rail 122 of clipper 124 has a notch 126, as shown in FIG. 7, corresponding in location, orientation, and cross-sectional to pin 116, so that notch 126 mates with pin 116.
  • notch 126 is preferably approximately V-shaped and located in the middle of rail 122. If a different position is used for notch 126, then a corresponding position should be used for pin 116.
  • the shape of pin 116 does not have to exactly match the shape of notch 126, however, so long as pin 116 fits within notch 126.
  • the guide rail 128 of clipper 124 has a corresponding protrusion 130. Accordingly, as clip 102 rides on rail 122, and is held in place on rail 122 by guide rail 128, pin 116 mates with notch 126 and protrusion 130 mates with indentation 114. More precise control of clip 102 is thereby achieved, as clip 102 is constrained from lateral movement.
  • Clipper 124 has a punch 200 having a shape that corresponds to top surface 108 of clip 102. Accordingly, as shown in FIG. 8, punch 200 has a punch pin 202 that preferably corresponds in location, orientation, and cross-sectional shape to indentation 114, so that pin 202 mates with indentation 114.
  • punch 200 closes clip 102 over packaging material 140, as shown in FIG. 9, clip 102 creates annular space 132, by virtue of legs 1 10, 1 12 being folded against each other to form a closed loop. Pin 1 16, however, projects into annular space 132 and therefore into the packaging material 140 gathered therein.
  • pin 116 vastly decreases the likelihood that the packaging material 140 can be pulled out of annular space 132.
  • the packaging material 140 is therefore fastened much more securely.
  • FIG. 9 illustrates netting used as packaging material 140
  • clip 102 will work equally well with solid bags or tubular casings.
  • material can be encased in a solid plastic bag, and the neck of the bag can be gathered and then clipped.
  • Pin 116 projecting into annular space 132, and therefore into the packaging material 140 gathered therein, will prevent the plastic from slipping through annular space 132 and releasing the contents of the bag.

  • Stick 300 is preferably fifty clips 302A, 302B, 302C, etc., preferably made of an injection-molded plastic, and preferably injection molded in one piece, although only three clips 302 are shown in stick 300 in FIG. 10 for ease of illustration. Different numbers of clips 302 in stick 300, or formation of clips 302 into a reel, is possible. Clips 302A, 302B, 302C, etc., could also be made of metal or another material.
  • Clip 302 has a top section 304 with an internal face 306 and an external face 308. As illustrated in FIG. 1 1, top section 304 is generally rounded, but it can be straight and can have shaip comers if desired. Two legs 310, 312 extend from opposite ends of top section 304. Accordingly, legs 310, 312 and top section 304 define a space 314 within clip 302.
  • Each leg 310, 312 terminates, at an end opposite top section 304, in a foot section 316.
  • Each foot section 316 has a protrusion 318 extending into space 314.
  • Legs 310, 312 preferably are narrower in front cross-section, as shown in FIG. 11 , at an end having protrusion 318, than at an end meeting top section 304.
  • outer edge 320 of leg 310 is parallel to outer edge 322 of leg 312, so that the narrowing of each leg 310, 312 occurs from sloping of inner edge 324 of leg 310 and inner edge 326 of leg 312, relative to outer edges 320, 322, respectively.
  • Top section 304 has a shoulder 328.
  • Shoulder 328 is provided at generally the midpoint of top section 304, between legs 310, 312, and is preferably rounded at the top in cross section.
  • the position of shoulder 328 between legs 310, 312 can be closer to one leg or to another, however.
  • a rounded shoulder 328 is preferable, as it is easier to manufacture, other shapes can be used, such as hemispherical or hemi-oval, or rectangular, square, or any higher-order polygon.
  • Each clip 302 is preferably approximately 200 millimeters deep. Each clip 302 is separated from adjacent clips 302 in stick 300 by approximately 50 millimeters. Shoulder 328 has a connecting portion 330 that extends laterally across top section 304 of each clip 302, so that each clip 302 is connected to form a one-piece stick 300. In use, the connecting portions 330 of shoulder 328 will easily snap, allowing an individual clip 302 to be removed from stick 300. Connecting portions 330 could extend from a different portion of clip 302 than shoulder 328.
  • Clipper 400 can be any conventional clipper, modified, however, as described herein.
  • Clipper 400 is preferably a manual clipper, such as a Model EZ 4212 sold by Poly-clip System Corp., or a single or double automated clipper, such as a Model TCSA 65 sold by Poly-clip System Corp.

  • rail guide 404 has a cross-sectional shape corresponding to the top section 304 of clip 302, including the cross-sectional shape of shoulder 328.
  • Indentation 406 in rail guide 404 corresponds in location, orientation, and cross-sectional shape to shoulder 328, so that indentation 406 mates with shoulder 328. Accordingly, clipper 400 thereby holds clips 302 securely.
  • the clips 302 of stick 300 are fed to the die area of clipper 400, under punch 408, as shown in FIG. 15.
  • the first clip 302A in a stick 300 (or the first clip 302A in a reel) is oriented under punch 408 and over the die in a conventional manner, and the neck of the packaging material 340 is arranged within space 314.
  • Punch 408 strikes top portion 304 of clip 302, forcing legs 310, 312 into the die in a conventional manner, and causing legs 310, 312 to bend inward, sealing the neck of the packaging material.
  • Clipper 400 can cause legs 310, 312 to bend inward in a V-shape, or "wrap around” configuration, or to bend inward in a W-shape, or "butt to butt” configuration, as is known in the art, depending on the preference of the user and the type of packaging being sealed.
  • FIG. 16 shows packaging material 340 clipped in clip 302 in a "butt to butt" configuration.
  • the punch 408 of clipper 400 has a concave, arcuate shape corresponding to the convex, rounded top portion 304 of clip 302.
  • Punch 408 also has an indentation 410, having a cross- sectional shape corresponding in location, orientation, and cross-sectional shape to the cross-sectional shape of shoulder 328, as shown in FIG. 6, so that, on the punch stroke of clipper 400, indentation 410 mates with shoulder 328.
  • Each individual clip 302 is thereby controlled well within the die area of clipper 400, as clip 302 is constrained from lateral movement during the clipping operation.
  • a slight misalignment of an individual clip 302 within the die area of clipper 400 is automatically corrected by punch 408, as shoulder 328 will self-align into indentation 410, thereby providing superior performance.
  • Clipper 400 thereby provides superior control of clip 302 within the die area, resulting in more accurate clipping of packaging material.
  • legs 310, 312 will bend inward easily to seal the packaging material. Because of the tapering shape of legs 310, 312, wherein legs 310, 312 are thicker in the ai'ea that bends, the plastic will deform to close legs 310, 312, rather than breaking. Other materials are possible.

  • Punch 710 strikes top section 604 of clip 602, forcing legs 610, 612 into die 712 in a conventional manner, and causing legs 610, 612 to bend inward, sealing the neck of packaging material 640.
  • Die 712 can cause legs 610, 612 to bend inward in a V- shape, or "wrap around” configuration, or to bend inward in a W-shape, or "butt to butt” configuration, as is known in the art, depending on the preference of the user and the type of packaging being sealed.
  • FIG. 2.3 shows packaging material 640 clipped in clip 602 in a "butt to butt" configuration.
  • Punch 710 of clipper 700 has a concave, arcuate shape corresponding to the convex, rounded top portion 604 of clip 602.
  • Punch 710 also has an indentation 714, having a cross- sectional shape corresponding to the cross-sectional shape of shoulder 628, as shown in FIG. 6, so that indentation 714 mates with shoulder 628.
  • Each individual clip 602 is thereby controlled well within the die area of clipper 700, as clip 602 is constrained from lateral movement during the clipping operation.
  • a slight misalignment of an individual clip 602 within the die area of clipper 700 is automatically corrected by punch 710, as shoulder 628 will self-align into indentation 714, thereby providing superior performance.
  • Clipper 700 thereby provides superior control of clip 602 within the die area, resulting in more accurate clipping of packaging material.
  • legs 610, 612 will bend inward easily to seal the packaging material. Because of the tapering shape of legs 610, 612, wherein legs 610, 612 are thicker in the area that bends, the plastic will deform to close legs 610, 612, rather than breaking. Other materials are possible.
  • identification information 802 is supplied. Both poultry products and meat products in the United States must be labeled with the official establishment number of the establishment where the poultry or meant article was processed. This embodiment will be described in connection with the packaging of poultry products, but similar considerations apply to the packaging of meat products.
  • the identification information 802 as discussed herein can apply to non-food products as well. Furthermore, identification information 802 will be described as applied to clip 302, but identification information 802 can be used on other clips as described herein.
  • the outer edges 320, 322 of clip 100 are flat surfaces.
  • identification information 802 is supplied on at least one of outer edges 320, 322 of each clip 302.
  • Identification information 802 is preferably the official establishment number of the establishment where the poultry will be processed.
  • Identification information 802 can be a plant number, stock number, customer number, or any other information that the clip user desires to have on its clips 302.
  • Identification information 802 can be supplied on one of outer edges 320, 322 by imprinting that information with a laser, by forming that information in the plastic injection molding process, by applying that information with a printer, such as an ink jet printer, or by burning that information into the surface.
  • Identification information 802 as illustrated is a combination of Arabic letters and numerals, to show an official establishment number, but identification information 802 can also be words, a bar code, a digital code, other symbols, or any other means of conveying information.
  • Clips 102, 302, 602 as described herein can be used to enclose any type of mateiial in a bag, in a tubular package, in a net, either bag-type or tubular, in a casing, either tubular or roll-slock, or in any other application in which packaging material must be closed.
  • a label may also be placed at the neck of the packaging material, so that the label is clipped to the package, such as a label containing information as to the provenance, weight, lot number, or expiration date of the packaged material, as described in, for example, the '297 patent referenced above.
  • Clips 102, 302, 602 as described herein can also be used to attach together two planar pieces of material to each other, where control of the clip 102, 302, 602 within the clipper and within the die area is desired.
