Definitions

  • the present invention relates to a new and improved structure for absorbing liquids from food products. More particularly, the invention relates to an absorbent pad for meat and poultry products.
  • Such products as meat and poultry naturally contain liquids/juices and occasionally added water which with time will drain from the product. When such products were sold at butcher counters, these liquids would drain to the bottom of the display case. However, when the same products are packaged within relatively air- and liquid-tight packages, these liquids end up collecting within the tray and sub­sequently leaking during transportation and handling. Market analysis has revealed that the consumer finds such liquid-containing packages to be less than desirable. Consequently, many such packages today employ an absorbent material in the bottom of the tray to absorb the liquids as they are released from the food product.
  • tissue and/or wood pulp fluff which is usually encased within a material such as plastic film or tissue paper.
  • materials such as plastic film or tissue paper.
  • Many other designs have also been developed to be used generally with food packaging. Other designs have been specifically developed to act in concert with a particular package design.
  • a liquid absorbing and concealing device which includes both a liquid absorbing bag and a tray is disclosed in DuPuiS, U.S. Patent No. 3,156,402.
  • the liquid absorbing bag is composed of two superposed sheets of material which are sealed by heat welding or adhesive around their marginal edges.
  • the sheets may be formed from material such as waxed paper, cellophane, polyethylene, or other thermoplastic or thermosetting plastic materials.
  • Each of the sheets contain a series of openings or holes to permit fluid to enter the bag from either the top or the bottom by the use of gravity and capillary action.
  • United States Patent No. 3,940,062 to Rainey discloses a moisture pad for use in hydration of consumable vegetables which have been sealed in plastic and refrigerated.
  • the pad includes a water containing reservoir element which is encased in a sheath of moisture-proof film with openings for escape of the moisture from the reservoir.
  • the pad consists of a sponge or other absorbent or porous pad which is saturated with water to act as the water reservoir.
  • the hydrated sponge is then located within a flexible water-impervious envelope which is sealed or otherwise closed about its periphery.
  • the envelope is then provided with openings to allow for the escape of moisture from the absorbent sponge within.
  • liquid-absorbing device in this case a liquid-absorbing sectional pack
  • the pack is formed from upper and lower contiguous filter sheets which are bonded to each other at the outermost contiguous edges thereof to form an enclosure.
  • the enclosure itself is divided into a plurality of sectional compartments which are isolated from each other by dissolving barrier sheets which consist essentially of a water-soluble carboxymethylcellulose compound.
  • barrier sheets consist essentially of a water-soluble carboxymethylcellulose compound.
  • Each of the sectional compartments contain a predetermined quantity of absorbent granules and the barrier sheets function to dissolve when the granules have absorbed a pre-determined amount of moisture so as to provide for increased space in which to contain the moist granules.
  • a receptacle for moisture-exuding food products is described in U.S. Patent No. 4,321,997 and U.S. Patent No. 4,410,578 both to Miller.
  • a receptacle is provided for containing and displaying food products which tend to exude juices or liquids which comprises a supporting member such as a tray or bag, and an absorbent pad associated therewith.
  • the absorbent pad comprises a mat of liquid-absorbent material such a wood fluff, an upper liquid-impermeable plastic sheet overlying the absorbent mat, and a bottom plastic sheet underlying the absorbent mat.
  • At least one of the sheets is perforated, and rigid spacer means is disposed between the two sheets to maintain their separation under a compressive load such that the ability of the pad to absorb liquids is unimpaired when the pad is subjected to compressive loading from the food product resting thereon or the like.
  • a receptacle and absorbent pad for containing and displaying food products which tend to exude juices or liquids are disclosed in U.S. Patent Nos. 4,275,811 and 4,382,507 both to Miller.
  • the pad comprises a mat of liquid absorbent material, an upper liquid impermeable sheet overlying the absorbent mat and a perforated bottom sheet underlying the absorbent mat.
  • the absorbent mat is composed of a relatively thick layer of wood fluff and a relatively thin layer of tissue-like paper wadding which may be interconnected by embossing.
  • various additives may be added to increase liquid absorbency.
  • the absorbent pad is made from a nonwoven fabric material such as viscose rayon, superabsorbent viscose rayon, or polyvinyl alcohol.
  • a nonwoven fabric material such as viscose rayon, superabsorbent viscose rayon, or polyvinyl alcohol.
  • One side of the pad has a layer of binder material to provide a surface with reduced absorbency as compared to the remainder of the pad with the remainder of the pad being free of binder.
  • the pad may have apertures formed therein to allow fluid to pass through the binder layer and into the remainder of the nonwoven material.
  • the fibers of the nonwoven material are entangled by needle punching or preferably by the use of high-pressure water jets. The web is then dried and after drying a binder is applied to the one surface of the pad.
  • a food tray for supporting, containing, and displaying food products which tend to exude or purge juices or liquids is disclosed in U.S. Patent No. 4,576,278 to Laiewski.
  • the tray has a false bottom which leads to an exudate reservoir.
  • the false bottom is made from a perforated liquid-­impermeable thermoplastic film such as polyethylene.
  • each of the above-described devices The primary function of each of the above-described devices is to absorb the fluids which are exuded from packaged food products. Leaky packages are among the foremost complaints received by food store operators. Their use in such products, therefore, adds to the cost of the overall product. As a result, a major driving force in the development of such products is to provide an absorbent structure which provides ample absorbency while employing cost-efficient components. Furthermore, such designs should yield products with good wet strength, resilience and fluid retention characteristics. Products such as tissue tend to break apart when wetted. Such materials also readily release their absorbed fluids when placed under a compressive load. This most notably happens when packages are stacked one upon the other.
  • the present invention also provides an absorbent structure which while having the capability of absorbing fluids does not aggressively extract the fluids from the food product.
  • the present invention relates to a new and improved structure for absorbing liquids from food products and in particular meat and poultry.
  • the absorbent structure comprises a top sheet of fluid permeable material such as a nonwoven spunbonded or meltblown material.
  • the top sheet may be constructed of a fluid impermeable material such as plastic with at least one perforation therein to allow fluid passage therethrough.
  • the bottom sheet is constructed of a fluid impermeable material.
  • An absorbent inner core of pulp coform material is positioned between and joined to the top and bottom sheets.
  • the pulp coform material contains between 50 and 90 percent by weight wood pulp fluff (based upon the weight of the absorbent core) and between 10 and 50 percent by weight synthetic fibers. Included within the absorbent core there may be placed superabsorbent material such as carboxymethyl­cellulose.
  • the top and bottom sheets are sealed about their periphery to create a fluid collection pouch with an inner chamber to house a stratified absorbent core.
  • the stratified absorbent core includes a first layer of pulp coform material adjacent the top of the pouch and a second layer adjacent the bottom of the pouch.
  • the first layer is substantially devoid of superabsorbent material and the second layer contains a superabsorbent such as carboxymethylcellulose in a weight percent add on of from 5 to 100 percent based upon the total weight of the absorbent inner core.
  • the present invention relates to an absorbent pad for collecting and retaining fluids from foods, most notably meat and poultry.
  • Much of the meat and poultry sold in stores today is prepacked in styrofoam trays and wrapped with transparent polymeric film.
  • the packages when stacked are rarely in a completely horizontal plane. As a result, the juices absorbed by the pad will commonly be compressed, at least partially, back out of the pad and pool in the lowest point of the package. Consequently, there is still a high probability that the package will leak.
  • an absorbent structure 10 for collecting and retaining fluids released from foods.
  • the structure 10 has an outer cover including a fluid permeable top sheet 12 and bottom sheet 14 of fluid impermeable material such as polyethylene film.
  • a fluid absorbent inner core 16 Positioned between and joined to the top and bottom layer 12 and 14 is a fluid absorbent inner core 16 which is joined to the outer layers 12 and 14 by suitable means such as adhesives or embossments.
  • at least one perforation 18 in the top sheet 12 which may take the form, for example, of a hole, slit, or capillary funnel.
  • the top sheet 12 is supplied with a plurality of perforations 18 to facilitate transfer of fluid into the absorbent core 16.
  • the top sheet 12 may be formed from a fibrous nonwoven material such as a spunbond or meltblown which will allow the passage of fluids to the absorbent core 16.
  • the design of the absorbent core 16 of the present invention provides both good absorbency and structural integrity to resist the release of fluids when the core material 16 is placed under compression.
  • the absorbent core material 16 is comprised of a pulp coform material which is made from a mixture of wood pulp fluff and extruded thermoplastic synthetic fibers.
  • a pulp coform material which is made from a mixture of wood pulp fluff and extruded thermoplastic synthetic fibers.
  • One way to make this material is referred to as the pulp coform process which is disclosed in United States Patent No. 4,100,324 to Anderson, et al, which is commonly assigned to the Kimberly-Clark Corporation and incorporated herein by reference.
  • the pulp coform material contains between 50 and 90 percent by weight of wood pulp fluff and between 10 and 50 percent by weight of synthetic fibers based upon the total weight of the wood pulp fluff and synthetic fibers.
  • the wood pulp acts as the absorbent while the synthetic fibers, which are disposed throughout the wood pulp, make the composite more resilient both when wet and dry.
  • the wood pulp fluff is 100 percent softwood pulp, or softwood pulp containing up to 30 percent hardwood fiber.
  • Softwood pulp fibers generally exhibit fiber diameters in the range of 35 ⁇ m to 45 ⁇ m and lengths of 3 mm to 5 mm. After processing into coformed structures the fiber length is reduced and averages approximately 2 mm.
  • Hardwood fibers exhibit fiber diameters from about 14 ⁇ m to 32 ⁇ m with lengths in the range of approximately 1 mm to 2 mm.
  • the synthetic fibers are most typically made from extrudable meltblown thermoplastic materials such as poly­propylene or polyethylene fibers with an average fiber diameter of up to 10 ⁇ m and more preferably in the range of 2 to 6 ⁇ m. These fibers are discontinuous and as a result have a length generally in excess of the staple fiber wood pulp fluff material.
  • Densities for the pulp coform material used in the present invention range from about 0.03 g/cm3 to about 0.20 g/cm3 with various absorben­cies when tested using deionized water as the absorbing fluid. (See the absorbency graph of Figure 4).
  • a superabsorbent material 20 may be added to the pulp coform material of the core 16.
  • One method of adding such material is disclosed in United States Patent No. 4,604,313 which is assigned to the Kimberly-Clark Corporation and incorporated herein by reference. Any number of superabsorbents may be used with the absorbent structure 10, however, because the absorbent structure 10 is used in conjunction with food, the superabsorbent should be cleared by the United States Food and Drug Agency or any other re­levant authority.
  • One such preferred superabsorbent is carboxymethylcellulose (CMC) such as is sold by the Aqualon Company of Wilmington, Delaware under the designation A-250.
  • the superabsorbent may be added to the pulp coform material in powder or other form either during the formation of the coform material or thereafter.
  • the measure of the increase in fluid absorbency in the absorbent core 16 is dependent upon the amount of superabsorbent 18 added to the pulp coform material.
  • the superabsorbent 20 is added to the absorbent core 16 in a weight percent add on of from 5 to 100 percent based upon the total weight of the absorbent core material 16.
  • the absorbent structure 10 is placed between the food product (not shown) and the tray or other packaging material (not shown) with the perforated top sheet 12 in contact with the food product. As juices, etc., are released from the food product, they pass through the perforations 18 or the nonwoven material of the top sheet 12 and are collected and retained within the absorbent core 16. Unlike simple wood pulp fluff, the pulp coform material of the present invention is more resistant to compression when wet due to the use of the synthetic fibers. As a result, the absorbent structure 10 is less likely to release its fluids when compressed, especially if a superabsorbent 20 is being used.
  • FIG. 2 and 3 of the drawings A more self-contained and preferred embodiment 30 of the present invention is shown in Figures 2 and 3 of the drawings.
  • the absorbent structure 30 has a top sheet 32 and a bottom sheet 34 of the same materials as previously mentioned and an absorbent core 36 of pulp coform material.
  • One or more perforations 38 are present in the top sheet 32 if it is not made from a nonwoven material and a superabsorbent 40 as previously discussed may be used within the pulp coform material.
  • the top and bottom sheets 32 and 34 are sealed about their periphery 35 by adhesive, heat or other means.
  • the absorbent structure 30 may be made of two separate sheets 32 and 34 which are sealed about their entire periphery 35.
  • the top and bottom sheets 32 and 34 may be formed from a single sheet of material which is folded over on itself, thus only requiring sealing on three sides.
  • the absorbent structures 10 and 30 are not limited to square or rectangular shapes and may be designed in any other shape to suit the particular application.
  • the absorbent core 36 is comprised of a first layer 36a adjacent the top sheet 32 and a second layer 36b adjacent the bottom sheet 34. Both the first layer 36a and the second layer 36b are formed from the same pulp coform material as described with respect to the embodiment of Figure 1. Again, the pulp coform material should contain between 50 and 90 percent by weight wood pulp fluff and between 10 and 50 percent by weight synthetic fibers. If desired, the layers 36a and 36b may have the same or different ratios of wood pulp fluff and synthetic fibers.
  • the super-­absorbent 40 is only present in the second layer 36b.
  • the superabsorbent concentration should be from 5 to 100 percent by weight based upon the combined weight of the wood pulp fluff and synthetic fibers.
  • the superabsorbent material 40 is located away and separated from the fluid permeable top sheet 32. As a result, there is less likelihood that the superabsorbent 40 will filter through the perforations 38 in the top sheet 32 and come in contact with the food product.
  • a superabsorbent is used in an absorbent material, it increases the capillary action or "drawing power" of the absorbent. With food products, this can result in a premature dehydration of the food product. By distancing the superabsorbent from the food product, this drawing power is reducing while still allowing the enhanced utilization of the fluid retentive properties of the superabsorbent.
  • the absorbent structure 30 of Figures 2 and 3 may be provided with a fluid reservoir area 42 within the absorbent structure 30 between the absorbent core 36 and the sealed periphery 35.
  • the absorbent structure 30 is provided with a contained fluid run-off area for temporary storage of the fluids when the structure 30 is under severe compression or when the structure 30 has received more fluid than the absorbent core 36 can hold.
  • the absorbent structure of the present invention can more readily receive and contain fluids received from the food product stored within the food package (not shown).
  • by providing a self-contained system with perforations directly in contact with the food product there is less likelihood of pooling of fluids within the food tray and ultimate leakage from the container.
  • a pulp coform sample devoid of carboxymethylcellulose was subjected to the test procedure outlined above.
  • the sample had a basis weight of 75 g/m2 with 80 percent by weight pulp and 20 percent by weight polypropylene fiber.
  • Sample thickness was 1.02 mm and the bulk density was 0.073 g/cm3.
  • water absorbency was 1.05 g/6.45 cm2 surface area.
  • a pulp coform sample again devoid of carboxymethyl­cellulose was subjected to the test procedure outlined above.
  • the sample had a basis weight of 200 g/m2 with 80 percent by weight pulp and 20 percent by weight polypro­pylene fiber.
  • Sample thickness was 4.04 mm and the bulk density was 0.050 g/cm3.
  • water absorbency was 2.93 g/6.45 cm2 surface area.
  • the absorbency of pulp coform material can be increased by the addition of a superabsorbent material.
  • a thinner super­absorbent containing pulp coform material can be used in place of a thicker non-superabsorbent containing pulp coform material.
  • a thinner product with equal absor­bency can be achieved if so desired.
