Definitions

  • the present invention relates to a method and apparatus for making pre-padded food-containing bags for such products as fresh poultry and meat. More particularly, this invention relates to methods and apparatus for placing an absorbent pad into a food-containing bag made from a web of tubular thermoplastic material.
  • Poultry and meat are frequently sold in transparent plastic bags.
  • a problem with this type of packaging is that the poultry or meat, no matter how carefully prepared, contains residual blood and other fluids that flow out of the meat after it has been packaged.
  • the blood and other fluids accumulate in the package, thereby detracting from its appearance.
  • the blood and fluid sometimes leak from the package while the consumer is transporting it home from the market.
  • food bag manufacturers include an absorbent pad in the bag prior to loading the food product. The pad absorbs the exuded blood and fluid into the pad and also enhances the appearance of the finished bagged product.
  • the manual labor associated with placing the absorbent pad in the bag prior to product loading adds to the cost and time associated with this operation.
  • thermoplastic food bags with an absorbent pad for packaging food products.
  • One such patent is U. S. Patent No. 4,815,590 to Peppiatt, et al . that discloses a generally rectangular pad attached to the side closest to the bag opening so that the pad is not dislodged when the product is placed in the bag. The pad absorbs blood and other fluids in the meats to keep the package neat and clean and minimize the danger of leakage.
  • U. S. Patent No. 4,410,578 to Miller discloses an absorbent pad for use in a bag or tray intended to contain and display fresh food such as poultry or meat.
  • the absorbent pad includes a mat of liquid absorbing material, and liquid impermeable plastic sheets overlying and underlying the absorbent mat. At least one of the sheets is perforated, and a spacer is disposed between the two liquid impermeable plastic sheets to maintain their separation under the compressive load of the food product resting thereon, such that the ability of the pad to absorb liquids is unimpaired.
  • any exuded liquids will flow around the pad and enter the pad by capillary action through the perforated openings in the bottom sheet, and the liquids will be held out of contact with the food product minimizing contamination of the product, maintaining its appearance, and improving its shelf life.
  • thermoplastic food bag Such a bag would increase packaging rates and reduce labor cost at the packing plant.
  • US 3,254,828 discloses a method according to the pre-characterising section of claim 1.
  • Another object of the present invention is to provide an apparatus for making a food-containing bag having an absorbent pad therein from a web of thermoplastic tubular material.
  • Yet another object of the present invention is the provision of a method for manufacturing pre-padded food-containing bags that have fewer seals than conventional bags.
  • a further object of the present invention is to provide a pre-padded food-containing bag available in roll form.
  • the present invention provides a method of making bags from a tube of thermoplastic material comprising the consecutive steps of:
  • the result is a continuous web of bags containing absorbent pads at discrete intervals.
  • the present invention further provides a bag machine for forming bags, each bag having an absorbent pad therein from a roll of flattened tubular web material comprising the following means ordered sequentially:
  • a predetermined continuous length of lay-flat seamless tubular thermoplastic web is unwound from a roll.
  • the layers of the lay-flat tubular web are perforated at a predetermined length.
  • the tubular web is fed through a tube opener where the upper layer perforations are separated creating an opening.
  • the tubular web then passes to the inserter where during the seal dwell time, a pair of nip rollers, located at a predetermined distance from the web opening, squeeze the upper and bottom layers together. Air is blown into the opening in an amount sufficient to cause the upper layer of the tubular web to open sufficiently wide for an absorbent pad to be inserted through the opening.
  • the absorbent pad may have either pressure sensitive or low temperature food grade adhesive attached on one side thereof so that when the excess air is removed from the tubular web the pad is adhered to one of the layers.
  • the tubular web having the absorbent pad positioned between the layers, passes between laterally adjustable nip rollers to squeeze the air out of the tubing prior to entering the sealer.
  • a transverse seal is made.
  • the sealer is displaced transversely across the tubular web for delimiting a predetermined length serving to define the bag size.
  • the seal may be straight or curved.
  • the seal can be made using an impulse sealer which employs a hot wire.
  • the bags containing the pads may be wound into a roll and separated when used at the perforations in the bottom layer of the tubular web.
  • the method is similar to the first embodiment described above but differs in that when the tubular web passes through the perforator and opener the bottom layer of the tubular web is perforated and the upper layer is severed or cut.
  • a knife is provided on reciprocating base to cut a slit through the upper layer but not the bottom layer.
  • the perforations in the bottom layer are provided by perforation knife positioned in restraining block and piercing only the bottom layer.
  • the flat tubular web is slit along one side and the absorbent pad is inserted at a right angle to the direction of travel of the web and the slit side is heat sealed.
  • the packaging costs at the consumer level are reduced due to reduction in labor costs associated with manual placement of pads in bag and subsequent increase in productivity by the use of the pre-padded bags.
  • FIG. 1 a bag forming machine for making a pre-padded food-containing bag such as the one shown in FIG. 2 .
  • the bag 10 is made from conventional tubular thermoplastic packaging material that is defined by seals 30 and has a fluid-absorbing pad 25 placed therein.
  • the thermoplastic material will be polyethylene, although other thermoplastic materials known to those skilled in the art may be used, such as the materials disclosed in U. S. Patent No. 3,741,253 to Brax.
  • the bag-forming machine 100 includes a tubular web supply section 120 and a bag forming section 130 .
  • the tubular web supply section 120 includes a pair of cradles 123 mounted on a support base 121 and spaced apart from each other a sufficient distance to accommodate a roll 12 of tubular plastic material.
  • the continuous length of lay-flat seamless tubular web 11 may be unwound from the roll 12 and passed around guide roll 124 .
  • the tubular thermoplastic web 11 is drawn in a flattened condition from the supply section 120 to the bag forming section 130 through the nips of tensioning rolls 125, 126 and 127, 128 and around guide roll 129 .
  • a pair of drive rolls 131 , 132 forming a nip through which the tubular web 11 passes is provided.
  • the tubular web 11 passes around idler roll 133 and is guided by guide rollers 134, 135 , 136, 137 to the tube perforator and opener 140 .
  • the tubular web passes through the perforator and opener 140 where the bottom layer of the tubular web is perforated and the upper layer is severed or cut at a predetermined length.
  • a knife 141 is provided on reciprocating base 142 to cut the upper layer.
  • the perforations in the bottom layer are provided by perforation knife (not shown) positioned in restraining block 143 and piercing only the bottom layer.
  • perforation knife (not shown) positioned in restraining block 143 and piercing only the bottom layer.
  • To insert the pad it is necessary to open the layers of the tubular web 11 from each other so that air may be blown into the tube to make the tube wide enough to insert the pad.
  • There are several means for separating the layers from each other to create a bag opening such as an eccentric wheel ( FIG. 3 ) or vacuum cups (not shown).
  • the tubular web 11 then lead to the pad insertion section 150 by passing the tubular web 11 around guide roll 155.
  • pair of laterally adjustable nip rollers 151, 152 positioned prior to the sealer 160 and located at a predetermined distance from the opening in tubular web 11 to squeeze the upper and bottom layers together squeezing the air out of the tubular web.
  • the nip rollers are positioned from the opening 20 at a predetermined distance to correspond with the length between the perforations 17 ( FIG. 4 ).
  • the length of the bag 10 may be varied by changing the distance between the perforations 17 and changing the distance from the opening 20 at the pad inserter to the nip rollers.
  • Blower 153 blows air into the opening formed in the tubular web causing it to open wide enough to insert an absorbent pad. At the same time a pad 25 passes from pad inserter 154 through the opening in the tubular web where the pad comes to rest inside the tubular web 11 .
  • the pad inserter is mounted to vertically adjustable support 157 .
  • Sealer 160 is displaced transversely across the tubular web 11 for forming bag 10 at a predetermined a length.
  • the sealer 160 may include a sealing bar 161 which when in sealing position is disposed against restraining bar 162 opposite each other forms a transverse seal (straight or curved heat seal) to form the bag.
  • a hydraulic cylinder 163 is provided for advancing and retracting the seal bar 161 and restraining bar 162 toward and away from the tubular web 11 . It will be understood by those skilled in the art that means other than a hydraulic cylinder, e.g. electric motor, may be used to advance and retract the seal bar.
  • the continuous length of perforated, pre-padded bags then passes to winder assembly 170 where the bags are wound up in a roll 31 . When roll 31 is full the continuous length of pre-padded bags is shifted to a second roll 31' and roll 31 is removed and set up for another winding operation when roll 31' is full.
  • FIGs 3A-3E A method for making the pre-padded bags 10 is shown in FIGs 3A-3E wherein a roll 31 of individual bags 10 each having an absorbent pad 25 is produced.
  • a predetermined continuous length of lay-flat seamless tubular thermoplastic web 11 is unwound from roll 12 .
  • the lay-flat tubular web 11 has an upper layer 13 and the bottom layer 14.
  • the tubular web 11 is fed along a path of travel to a perforator 15 and backing bar 16 where the upper layer 13 and the bottom layer 14 of tubular web 11 are perforated at a predetermined length to define the length of the bag ( FIG. 4 ).
  • the perforations are shown by forming line 17 in FIG. 4 . In the case of the upper layer 13 the perforation is used to form opening 20 and in the case of the bottom layer 14 the perforation is used to separate each bag for the next succeeding bag.
  • the perforated tubular web 11 is fed to station #2 shown in FIG. 3B , through a tube opener where the upper layer 13 perforations are separated creating an opening 20 .
  • the opening is provided using eccentric wheel 18 acting against the upper layer 13 of the tubular web and a back up roller 19 to separate at the perforation in upper layer 13 .
  • the opening is formed by severing or cutting upper layer 13 and perforating the bottom layer 14.
  • the tubular web 11 next passes to station #3 for pad insertion from the pad inserter 24 where during the seal dwell time pair of nip rollers 21, 22 located at a predetermined distance from the opening 20 to squeeze the upper layer 13 and bottom layer 14 together to close off a section of the tubular web 11 ahead of the absorbent pad 25 so that when the air from air source 23 is blown into the opening 20 the upper layer 13 and the bottom layer 14 of the tubular web 11 are caused to separate sufficiently for absorbent pad 25 to be placed through the opening and into the tubular web.
  • the absorbent pad 25 is inserted inside the tubular web 11 through the opening 20 .
  • the pad 25 is dispensed from a roll of pads 24, such as DRI-LOC® absorbent pads available from Sealed Air Corporation, and inserted inline in the direction of travel of the tubular web.
  • pads 24 such as DRI-LOC® absorbent pads available from Sealed Air Corporation
  • FIGs 5 and 6 only bottom layer 14 of the tubular web is shown for clarity. Thus, because upper layer 13 is not shown, opening 20 is not shown.
  • an indefinite length of pads is fed intermittently at a predetermined time interval from a stock roll 24 a cutting device (not shown) severs the pads from each other. Each pad is then delivered at the predetermined time into the opening 20 of the tubular web. The blowing air assists in pushing the pad into the tubular web.
  • the absorbent pad may have either pressure sensitive or low temperature food grade adhesive on one side thereof so that when the excess air is removed from the tubular web 11 the pad is adhered to one of the layers, preferably the bottom layer 14 .
  • the excess air is removed from the tubular web 11 having the absorbent pad 25 positioned between the upper layer 13 and the bottom layer 14 .
  • station #4 one method of removing the excess air is to pass the tubular web 11 between laterally adjustable nip rollers 26, 27 to squeeze the excess air from the tubing prior to forming the bag.
  • Bags are then formed at station #5 by converting the tubular web 11 into a continuous series of connected end-seal bags 10 , each containing an absorbent pad as shown in FIG. 3E .
  • the bags may be formed by sealing the tubular web across its width at discrete intervals. As the tubular web 11 passes between sealer 28 and restraining bar 29 a transverse seal 30 is made by heated sealing member 28 . The sealing member 28 is displaced transversely across the tubular web 11 for delimiting a predetermined length serving to limit the size bag 10 . The sealing member 28 is moved toward the restraining bar 29 to form a seal 30 .
  • the seal 30 may be straight, as shown in FIG. 2 or curved as shown in FIG. 10 . It should be understood that any well-known method of sealing is used to form the bags 10 .
  • the bags containing the pads may be wound into a roll 31 . Alternatively, the bags may be folded along the seal and placed in a box until used.
