Definitions
- the present invention relates to compressed rolls of wound material and, more particularly, to a package for storing compressed rolls in a compressed form.
- the distribution of rolled paper products represents a multibillion dollar industry in the United States with one of the largest segments represented by the toilet or tissue paper segment, as well as the paper towel or kitchen towel market.
- the process by which both tissue and towels are made can be broken-up into two general steps.
- the first step involves the creation of the paper base sheet from pulp, while the second step involves converting the base sheet (from a large jumbo roll) to finished smaller roll products.
- tissue is designed to be soft and degrade in septic tanks
- kitchen towels are designed to be much stronger for use in absorbing spills, for use as placemats, and for cleaning.
- Tissue and towels are generally made using multiple layers of base sheet. Tissue tends to have minimal glue between the layers, and generally at selected spots, while the individual plies in paper towels are generally adhered across their entire surface area. Both tissue and paper towels are embossed to create patterns which also help in strengthening the paper.
- the pulp drying process plays a significant role in the creation of the end product, with through air drying (TAD) producing the softest paper. Papers made using the TAD process are used to form the highest quality tissue and towel papers.
- the converting machines used in the second step of the process for making both tissue and towels incorporate unwinders, embossers, rewinders, core handlers, gluers, accumulators, and log saws.
- these machines can produce as many as 1000 rolls of toilet paper or 400 rolls of paper towels per minute. Additional steps of wrapping, packing, and case packing are done after the log saw and are generally connected to the converting operation via conveyors.
- tissue and towels typically include an inner core for dispensing individual rolls.
- the central core of tissue and towels is generally made of paper and is difficult to collapse without causing significant distortion and separation from the sheet. This is due to the amount of adhesive applied to the paper when attached to the core, as well as the type of adhesive used in forming the core. Additional innovations in the resiliency and fabrication of the core is needed.
- Embodiments of the invention address the above needs and achieve other advantages by providing a package for storing compressed rolls of material.
- the compressed rolls of material are stored within a tray and sealed under vacuum with a lid, such as a film.
- a lid such as a film.
- the package reduces the inherent bulkiness associated with conventional packages, which facilitates the storage and transport of the package.
- a method for forming the package may be employed that includes compressing the rolls of material and sealing the rolls within respective cavities defined in a tray.
- the compressed rolls may be sealed under vacuum such that the rolls are maintained in their compressed state.
- a package in one embodiment, includes a tray defining at least one cavity, as well as at least one compressed roll of material (e.g., a paper roll) positioned within a respective cavity.
- the package also includes a lid attached to a surface of the tray covering the cavity to define an enclosed volume and to enclose the at least one compressed roll within the enclosed volume.
- the package includes a core positioned within the compressed roll.
- the core could be paper, foam, metallic, elastomeric, and/or thermoplastic materials, or the core could be a polymer core having a strain relief area.
- the core may include a plurality of layers of paper, and an elastomeric adhesive may be applied between respective layers of paper.
- the package could include a supplemental core attached to the tray.
- the tray may be a thermoformable material and may include a plurality of cavities defined therein. At least one compressed roll of material could be positioned within each of the cavities.
- the tray may include lines of weakening between respective cavities such that each cavity is capable of being separated from the tray along respective lines of weakening.
- the lid may include lines of weakening such that at least a portion of the lid may be removed from the tray to expose at least one of the cavities.
- the lid could include lines of weakening proximate to each cavity such that each roll may be removed from a respective cavity without affecting the compression and pressure of the rolls within the remaining cavities.
- the bond between the lid and the tray may have a peel strength to the tray of less than about 0.5 to 4 pounds/inch such that the lid is peelable from the tray.
- the tray may include a greater bending stiffness than the lid.
- the pressure within the enclosed volume may be less than the pressure outside of the enclosed volume, and one or more cavities may be partially evacuated such that the pressure within the package is sub-atmospheric.
- the present invention also provides a method for packaging one or more rolls of material.
- the method includes providing a tray defining at least one cavity and compressing at least one roll of wound material.
- the method further includes positioning the compressed roll of material within a respective cavity, and sealing the compressed roll of material within the cavity by attaching a lid to a surface of the tray covering the at least one cavity.
- the method includes cutting a log of rolled material into a plurality of rolls.
- the positioning step may include positioning each of the compressed rolls of material within a respective cavity.
- the method may also include providing a tray defining a plurality of cavities, as well as forming lines of weakening in the tray between respective cavities such that each cavity is capable of being separated from the tray along respective lines of weakening.
- the method could further include forming a sheet of material into a tray defining at least one cavity.
- the providing step could also include providing a tray having a handle.
- the method may include forming lines of weakening in a portion of the lid such that at least a portion of the lid is removable to expose a compressed roll of wound material positioned within a respective cavity.
- the method could include forming lines of weakening in the lid proximate to each cavity such that each roll may be removed from a respective cavity without affecting the compression of the rolls within the remaining cavities.
- Additional aspects of the method include compressing the roll of wound material with a platen.
- the method may include compressing the roll of wound material radially, while the compressing and positioning steps may occur approximately simultaneously.
- the method may further include the step of reducing the pressure within the at least one cavity before sealing the lid to the tray, and/or compressing the roll below the surface of the tray prior to sealing the lid to the surface of the tray.

Abstract
Description
- 1) Field of the Invention
- The present invention relates to compressed rolls of wound material and, more particularly, to a package for storing compressed rolls in a compressed form.
- 2) Description of Related Art
- The distribution of rolled paper products represents a multibillion dollar industry in the United States with one of the largest segments represented by the toilet or tissue paper segment, as well as the paper towel or kitchen towel market. The process by which both tissue and towels are made can be broken-up into two general steps. The first step involves the creation of the paper base sheet from pulp, while the second step involves converting the base sheet (from a large jumbo roll) to finished smaller roll products. While tissue is designed to be soft and degrade in septic tanks, kitchen towels are designed to be much stronger for use in absorbing spills, for use as placemats, and for cleaning.
- Tissue and towels are generally made using multiple layers of base sheet. Tissue tends to have minimal glue between the layers, and generally at selected spots, while the individual plies in paper towels are generally adhered across their entire surface area. Both tissue and paper towels are embossed to create patterns which also help in strengthening the paper. The pulp drying process plays a significant role in the creation of the end product, with through air drying (TAD) producing the softest paper. Papers made using the TAD process are used to form the highest quality tissue and towel papers.
- The converting machines used in the second step of the process for making both tissue and towels incorporate unwinders, embossers, rewinders, core handlers, gluers, accumulators, and log saws. Currently, these machines can produce as many as 1000 rolls of toilet paper or 400 rolls of paper towels per minute. Additional steps of wrapping, packing, and case packing are done after the log saw and are generally connected to the converting operation via conveyors.
- The sales of rolled paper products occur through retail stores, bulk discount stores, and more industrial “away from home” markets. One of the major difficulties for retailers involves the disposal of boxes and other packaging used to ship the finished rolls. The inherent bulkiness of rolled paper products also requires stores to order on-demand, with the overall cycle from production to sale occurring over several days (e.g., a 45 day period). Bulkiness also limits the ability of manufacturers to set-up production facilities far from end-users, as transportation of the finished goods can be cost-prohibitive. For end-users, the purchase, transport, and storage of tissue and towels also prove difficult because of the large inherent volume.
- Furthermore, tissue and towels typically include an inner core for dispensing individual rolls. The central core of tissue and towels is generally made of paper and is difficult to collapse without causing significant distortion and separation from the sheet. This is due to the amount of adhesive applied to the paper when attached to the core, as well as the type of adhesive used in forming the core. Additional innovations in the resiliency and fabrication of the core is needed.
- It would therefore be advantageous to provide a package that is capable of storing compressed rolls of material. In addition, it would be advantageous to provide a package that is economical and effectively stores the rolls of material in a compressed form, as well as a package that facilitates individual dispensing of individual rolls. Furthermore, it would be advantageous to provide a core for the compressed roll of material that is capable of collapsing and expanding without significant distortion of the core and/or compressed roll.
- Embodiments of the invention address the above needs and achieve other advantages by providing a package for storing compressed rolls of material. The compressed rolls of material are stored within a tray and sealed under vacuum with a lid, such as a film. Thus, the package reduces the inherent bulkiness associated with conventional packages, which facilitates the storage and transport of the package. Furthermore, a method for forming the package may be employed that includes compressing the rolls of material and sealing the rolls within respective cavities defined in a tray. The compressed rolls may be sealed under vacuum such that the rolls are maintained in their compressed state.
- In one embodiment of the present invention a package is provided and includes a tray defining at least one cavity, as well as at least one compressed roll of material (e.g., a paper roll) positioned within a respective cavity. The package also includes a lid attached to a surface of the tray covering the cavity to define an enclosed volume and to enclose the at least one compressed roll within the enclosed volume.
- In various aspects of the package, the package includes a core positioned within the compressed roll. The core could be paper, foam, metallic, elastomeric, and/or thermoplastic materials, or the core could be a polymer core having a strain relief area. In addition, the core may include a plurality of layers of paper, and an elastomeric adhesive may be applied between respective layers of paper. The package could include a supplemental core attached to the tray.
- Further variations of the package provide a tray having a handle defined therein. The tray may be a thermoformable material and may include a plurality of cavities defined therein. At least one compressed roll of material could be positioned within each of the cavities. Furthermore, the tray may include lines of weakening between respective cavities such that each cavity is capable of being separated from the tray along respective lines of weakening. Similarly, the lid may include lines of weakening such that at least a portion of the lid may be removed from the tray to expose at least one of the cavities. The lid could include lines of weakening proximate to each cavity such that each roll may be removed from a respective cavity without affecting the compression and pressure of the rolls within the remaining cavities. The bond between the lid and the tray may have a peel strength to the tray of less than about 0.5 to 4 pounds/inch such that the lid is peelable from the tray. The tray may include a greater bending stiffness than the lid. The pressure within the enclosed volume may be less than the pressure outside of the enclosed volume, and one or more cavities may be partially evacuated such that the pressure within the package is sub-atmospheric.
- The present invention also provides a method for packaging one or more rolls of material. The method includes providing a tray defining at least one cavity and compressing at least one roll of wound material. The method further includes positioning the compressed roll of material within a respective cavity, and sealing the compressed roll of material within the cavity by attaching a lid to a surface of the tray covering the at least one cavity.
- In various aspects of the method, the method includes cutting a log of rolled material into a plurality of rolls. The positioning step may include positioning each of the compressed rolls of material within a respective cavity. The method may also include providing a tray defining a plurality of cavities, as well as forming lines of weakening in the tray between respective cavities such that each cavity is capable of being separated from the tray along respective lines of weakening. The method could further include forming a sheet of material into a tray defining at least one cavity. The providing step could also include providing a tray having a handle. Moreover, the method may include forming lines of weakening in a portion of the lid such that at least a portion of the lid is removable to expose a compressed roll of wound material positioned within a respective cavity. In addition, the method could include forming lines of weakening in the lid proximate to each cavity such that each roll may be removed from a respective cavity without affecting the compression of the rolls within the remaining cavities.
- Additional aspects of the method include compressing the roll of wound material with a platen. The method may include compressing the roll of wound material radially, while the compressing and positioning steps may occur approximately simultaneously. The method may further include the step of reducing the pressure within the at least one cavity before sealing the lid to the tray, and/or compressing the roll below the surface of the tray prior to sealing the lid to the surface of the tray.
- Having thus described the invention in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
-

FIG. 5 is an enlarged isometric view of the compression process shown inFIG. 4 ; and -
FIG. 6 is an enlarged isometric view ofFIG. 4 illustrating the conveyors moving rolls of material from a cutoff saw to a vacuum packing area. - The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
- Referring now to the drawings and, in particular to
FIGS. 1 a-1 c, there is shown apackage 10 including a plurality of rolls ofmaterial 11 disposed therein. In particular, thepackage 10 includes atray 12 having a plurality ofcavities 13. As shown inFIG. 1 b, therolls 11 may be compressed and are capable of being positioned within arespective cavity 13. Thetray 12 may be sealed with alid 15 such that therolls 11 are maintained in a compressed configuration while positioned within thecavities 13. - As used herein, the term “package” is not meant to be limiting as the package could be any enclosure capable of storing compressed rolls therein. Thus, the package could be any suitable tray and lid combination that is capable of storing one or more compressed rolls of material. Furthermore, the term “roll” is not meant to be limiting, as the rolls may include various wound materials that are capable of being compressed. For example, the roll could be a paper, tissue, towel, or foam material wound about a core. The roll of material may be compressed into various shapes, but would typically be compressed radially (i.e., perpendicular to the longitudinal axis of the core), as will be explained in further detail below.
- The distortion of the
roll 11 once the package is opened and the roll is uncompressed can be appreciable. Through Air Dried tissue with an approximate density of 0.02 lbs/in3 compressed by 30% of its original volume, performs well and can be easily reshaped. However, therolls 11 may be various materials and densities if desired. For example, theroll 11 could be compressed between 20-70% of its original volume. - The
tray 12 may comprise one or more thermoformable materials such as one or more thermoplastic (e.g., one or more of polyethylene homo- or co-polymers and polypropylene homo- or co-polymers. Thetray 12 may define one ormore cavities 13 defined therein. Eachcavity 13 is sized and configured to receive a respective roll ofmaterial 11, and each cavity is separated from adjacent cavities by a divider orboundary 14 for separating individual rolls. As shown inFIGS. 1 a and 1 b, eachcavity 13 includes a rectangular cross section such that a roll ofmaterial 11 that is compressed may be positioned therein. Furthermore, thetray 12 may also include ahandle 16 that is formed in one end of the tray. Thus, thehandle 16 may be integrally formed in thetray 12 or separately attached thereto and be used to carry thepackage 10. Thehandle 16 could be an aperture extending completely through a portion of thetray 12, or a recess or the like formed in the tray, and could be formed at various locations on the tray. In addition, thetray 12 could include a hanging rack hole (not shown) formed therein such that thepackage 10 may be placed on hanging racks, such as for retail. - The
lid 15 may comprise a film that is sealed to thetray 12. Thelid 15 may be sealed at least about the outer periphery of thetray 12 and may also be sealed alongboundaries 14 definingindividual cavities 13. Thus, thelid 15 could be a single sheet of material that seals all of thecavities 13. Alternatively,individual lids 15 could be sealed torespective cavities 13 if desired. Various techniques may be employed to seal thelid 15 to thetray 12, such as with an adhesive or by heat sealing. Thelid 15 may be permanently affixed or peelable from thetray 12. For example, the peel strength between thelid 15 andtray 12 may be about 0.5 to 4.5 pounds/inch such that at least a portion of the lid is peelable from the tray. The peel strength is measured in accordance with ASTM F88-94. For further discussion of peel strength, see U.S. Pat. No. 6,630,237 to Rivett et al., entitled “Peelably Sealed Packaging, which is incorporated herein by reference. - The
lid 15 may be sealed to thetray 12 to not only maintainindividual rolls 11 withinrespective cavities 13, but also to help maintain a vacuum that is provided within the cavities. Although the seal between thelid 15 andtray 12 may be airtight, generally the seal between the lid and tray is capable of maintaining the pressure within thecavities 13 below atmospheric pressure. For example, the air pressure inside thepackage 10 may be at least about, and/or at most about any of the following: 14, 13, 12, 10, 8, 6, and 5 psia. In addition, the pressure differential between the external pressure and the internal pressure within the closed chamber may be at most about, and/or at least about any of the following, for example: 0.5, 1, 2, 3, 4, 5, 6, 8, and 10 psia. Furthermore, the pressure inside of the of theenclosed cavities 13 may be less than the pressure outside of the cavities (e.g., 14.7 psia) for at least about any of the following number of days: 30, 40, 50, 60, 90, 120, and 180 days. In an additional embodiment of the present invention, the pressure inside of thepackage 10 may less than the pressure outside of the package at least momentarily. Additionally, the volume of thecavities 13 may at least partially collapse over time (e.g., 1, 2, 12, and 24 hours) as the inherent counterforce of therolls 11 against thelid 15 andtray 12 equilibrates. - The
lid 15 may include one or more lines of weakening 17 (e.g., lines of a plurality of perforations or lines of scoring) such thatindividual cavities 13 can be opened along the lines of weakening without opening adjacent cavities. Thus, individual rolls 11 may be removed without affecting the compression of adjacent rolls. In other words, the remainingunopened cavities 13 remain closed, compressed, and under vacuum such that the rolls are also remain protected from contaminants. The lines of weakening 17 may be located along one or more edges orboundaries 14 about the periphery of thetray 12 or between eachcavity 13, or at any other desired location such that aroll 11 is capable of being accessed and removed via the lines of weakening. In addition or alternatively, thepackage 10 may include lines of weakening extending between eachcavity 13. Lines of weakening betweencavities 13 allows for the separation of individual cavities from adjacent cavities. - The
tray 12 andlid 15 can be various sizes, configurations, and materials in various aspects of the present invention. For instance, thetray 12 andlid 15 could be a thin flexible film or a thick and substantially inflexible material, but are generally capable of withstanding a vacuum that is drawn from the tray. For example, thetray 12 andlid 15 could be any of the following thicknesses: 0.25, 0.5, 1, 2, 4, 5, 8, 10, 12, 15, and 20 mils. Generally, thetray 12 includes a greater bending stiffness than thelid 15 to provide support and facilitate transport and storage of thepackages 10. Moreover, althoughFIGS. 1 a-1 c illustrate atray 12 having fourcavities 13, the tray may include one or more cavities. In addition, although thetray 12 andcavities 13 are illustrated as having a rectangular cross section, the tray and/or cavities could be various cross sections, such as a square or circle, and could be capable of receiving compressed rolls 11. - Furthermore, each of the
tray 12 andlid 15 can include one or more barrier resins to reduce the air (i.e., oxygen) permeation rate through the tray and lid. For example, thetray 12 andlid 15 could include ethylene/vinyl alcohol copolymer (“EVOH”), polyvinyl alcohol (“PVOH”), vinylidene chloride polymers (“PVdC”), polyalkylene carbonate, polyester (e.g., PET, PEN), polyacrylonitrile (“PAN”), and polyamide. Thetray 12 andlid 15 may include various amounts of barrier resins such as, for example, 50%. For a more detailed discussion of barrier resins, see U.S. Pat. No. 6,769,227 to Mumpower et al., entitled “Package Including a Lidstock Laminate,” which is incorporated herein by reference. Thetray 12 andlid 15 could also be metallized or include a foil laminate to decrease the air permeation rate. - Each roll of
material 11 is wound about arespective core 19. Thecore 19 is typically cylindrical having a hole defined along its longitudinal axis, where the hole may receive a spindle of a dispenser or other mechanism for facilitating unrolling of theroll 11. The core 19 could be various materials such as a paper, foam, metallic, elastomeric, or thermoplastic material. Thecore 19 is capable of being compressed, as well as expanding when thelid 15 is removed from thetray 12. An external force, such as pushing radially on theroll 11, may be required to aid in expanding thecore 19 to its original shape or near original shape. However, thecore 19 may experience some distortion during the compression and expansion of theroll 11. -
FIG. 2 illustrates a modified extrudedplastic core 19 with astrain relief area 28 designed to store the energy during collapse of the tissue core indirection 29. Thestrain relief area 28 extends parallel to the longitudinal axis of thecore 19 and provides a flexible hinge for facilitating compression of the core. For example, thestrain relief area 28 could be made by extruding a hinge along the inner wall of the core, where the hinge comprises a small flexible section of plastic with a “V” notch located at its bending point such that the hinge may bend about the “V” notch. In addition, paper cores including a plurality of layers of paper secured together with elastomeric adhesives may be employed to prevent disintegration or peeling when compressing therolls 11 andcores 19. Moreover, thecore 19 could be configured to self-expand to its original shape or near original shape without any external force. - While replacement of the core 19 with a more compressible energy-storing core is possible, it is typically not practical to do so. Instead, a modified insertion core can be provided as an adjunct to the package. For example,
FIG. 3 shows the attachment of anextra core 19′ to thepackage 10 to form apackage 30. Theextra core 19′ is provided to allow consumers to either replace the core currently positioned within theroll 11, or position the core within the existing core to maintain consistent rolling characteristics in a dispenser. In one embodiment of the present invention, an additional cavity may be formed in thetray 12 for accommodating the core 19′. Furthermore, although thecore 19 andextra core 19′ are typically hollow, the core could be solid in order to achieve a desired resiliency and/or to provide additional support for a particular material. -
FIG. 1 a illustrates rolls ofmaterial 11 placed above athermoformed tray 12 with correspondingcavities 13 and anintegrated handle 16. Therolls 11 are compressed into the form shown inFIG. 1 b and positioned intocavities 13. Therolls 11 are shown as having a rectangular cross section; however, the rolls could be compressed to various cross sections (e.g., oval) depending on the type of material or the amount and/or direction of the compressive force on the roll. The process of compressing therolls 11 can be done outside or inside of thecavity 13 and, in some cases, may be used to create the shape of thecavity 13. Alid 15 is secured to theouter edges 18 of thetray 12 forming the completedpackage 10. Upon removal of thelid 15, theroll 11 may expand outwardly to its original shape or to a shape that includes some distortion due to the compression of the roll andcore 19. - Moreover,
sequential cavities 13 can be formed, filled, and sealed to produce a completed cluster ofcompressed rolls 11 stored within thepackage 10. Filling of thecavity 13 with acompressed roll 11 may be performed in such a manner to prevent the roll from expanding past the open top end of the cavity. Theroll 11 may be compressed to a greater degree than required due to the fact that the roll may expand towards its original shape before the roll is sealed within acavity 13. Therefore, during the time theroll 11 expands to the open top end, the top end may be sealed with thelid 15 while the pressure is reduced. -
FIGS. 4, 5 , and 6 illustrate one embodiment of the present invention, which provides a production system for forming and filling the package in the sequence described inFIGS. 1 a, 1 b, and 1 c. The production of thepackage 10 is typically situated immediately after alog cutter 50 that slices tissue logs 24 into individual rolls, and therolls 11 are transported in groups 31 via aconveyor 25 to astation 22 for compressing the rolls within respective packages.Base tray material 60 is unwound fromroll 61 and formed atstation 21 intotrays 12.Individual cavities 13 are formed within each tray, and ahandle 16 may also be formed therein if desired. Therolls 11 are compressed in group 31 atstation 22 by aplaten 40 and forced intocavities 13. A top layer 26 (i.e., lid 15) is sealed to thetray 12 atstation 23 while therolls 11 are compressed and air is evacuated from thecavities 13.Station 23 may also print, cut, and perforate both thetop layer 26, as well as thetray base material 60 betweencavities 13. In some cases,station 27 applies asupplementary core 41 to thepackage 10 to form thepackage 30. Thepackage area 70. Transport of thefinished packages packages - Various processes or techniques may be employed to form the
packages rolls 11 could be compressed with theplaten 40 before positioning the rolls within respective cavities 13 (FIG. 5 ), orstations 21 and 22 (FIGS. 4 and 5 ) could be combined into a single operation such that compressing the rolls while positioned on thetray base material 60 also forms individual cavities. Furthermore, rolls 11 may be cut, compressed, and/or sealed individually rather than as a group 31.Trays 12 may be formed using various processes such as thermoforming or injection molding. Moreover, additional processes may be employed such as a converting process for making rolls of tissue or towels. - The present invention may provide one or more advantages. For example, the
package 10 stores compressed rolls of wound material, such as rolled tissue and towels, which significantly reduces the inherent bulk of these products and facilitates the purchase, transport, and storage of the rolls. Thus, packages are aesthetically pleasing, and the amount of packaging required to ship the rolls of material from a manufacturing facility to a retailer is reduced. The packages may be formed consistently into regular shapes such that handling and storage of the packages, such as by stacking multiple packages, is improved. In addition, the process for packaging the compressed rolls of material may be integrated with current manufacturing processes generally used to make rolls of material. Moreover, the package can maintain the compressed rolls in a compressed state without bulging, and each compressed roll may be stored within individual cavities defined in the tray. The package may provide for individual opening of sequential cavities of the package, as well as the separation of a cavity from the tray itself. When removed from the tray, the compressed rolls of material and/or core may expand to a usable form. The core may be specifically configured to collapse and expand between compressed and uncompressed positions, which reduces the incidence of damage to the core and/or roll of material. - Many modifications and other embodiments of the invention set forth herein will come to mind to one skilled in the art to which the invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the invention is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
