DETAILED DESCRIPTION
(16) With reference to
(17) In some embodiments, the substrate 20 of the article of manufacture 10 may comprise a pliable element. Without limitation, such a substrate 20 may comprise a fabric. Any fabric suitable for the article of manufacture may be used. For example, in embodiments where the article of manufacture 10 is a weighted blanket, the substrate 20 may comprise a fabric that imparts a surface of the weighted blanket with one or more desired characteristics, such as a particular texture (e.g., softness to the touch, etc.), cooling properties (e.g., moisture wicking, ventilation, etc.), or the like. In some embodiments, the fabric may substantially lack stretchability; a fabric that substantially lacks stretchability may stretch due to a weave of the fabric, but lack stretchable fibers. In other embodiments, the fabric may be stretchable. Without limitation, a stretchable fabric may comprise a two-way stretch fabric or a four-way stretch fabric that may be stretched to its full extent without causing the elastomeric element 30 to delaminate from the substrate 20.
(18) With added reference to
(19) In various embodiments, the solid structures 31 of the elastomeric element 30 may be printed onto the substrate 20. In more specific embodiments, the solid structures 31 of the elastomeric element 30 may comprise continuous elongated elements that overlap themselves and/or each other to define the voids 33 of the elastomeric element 30. For example, such a solid structure 31 may follow a winding path (e.g., an elongated, interconnected series of partially superimposed loops 32; a meandering path, a path resembling a wave, etc.) over at least a portion of the substrate 20, over another portion of the same solid structure 31, and/or over another solid structure 31.
(20) Any of a variety of suitable materials may be used to define the solid structures 31 of the elastomeric element 30 and, thus, the elastomeric element 30 itself. In some embodiments, the solid structures 31 may be defined from an elastomeric polymer. The elastomeric polymer may adhere well to the substrate 20 and have a sufficient density to impart the elastomeric element 30 with a desired weight and density. The elastomeric polymer may also compress under a load and then resiliently return to a relaxed state once the load is removed. In embodiments where the substrate 20 is stretchable, a stretchability and a resilience of the elastomeric polymer may match or exceed a stretchability and a resilience of the substrate 20, which may enable the substrate 20 to be stretched to its full extent. Thus, the elastomeric element 30 may not hinder stretching of the substrate 20 or delaminate from the substrate 20. Without limitation, the elastomeric polymer may comprise an extended triblock copolymer, such as those disclosed by the '137 Patent.
(21) In embodiments where the article of manufacture 10 includes a cover 40, the cover 40 may comprise any material suitable for the intended use of the article of manufacture 10. In embodiments where the article of manufacture 10 comprises a weighted blanket, the cover 40 may comprise a fabric. The fabric of the cover 40 may have one or more desired characteristics, such as a particular texture (e.g., softness to the touch, etc.), cooling properties (e.g., moisture wicking, ventilation or breathability, etc.), or the like. The fabric may substantially lack stretchability. Alternatively, the fabric of the cover 40 may be stretchable.
(22) In some embodiments, peripheral edges 42 of the cover 40 may be secured to peripheral edges 22 of the substrate 20. The peripheral edges 42 of the cover 40 may be secured directly to the peripheral edges 22 of the substrate 20. Alternatively, the peripheral edges 42 of the cover 40 and the peripheral edges 22 of the substrate 20 may be joined to an intervening element, such as a gusset (e.g., a strip of fabric in embodiments where the substrate 20 and the cover 40 comprise fabrics, etc.), a trim element (e.g., piping, another embellishment, etc.), or the like. As an example, the peripheral edges 42 of the cover 40 may be sewn directly or indirectly to the peripheral edges 22 of the substrate 20. As another example, the peripheral edges 42 of the cover 40 may be adhesively secured directly or indirectly to the peripheral edges 22 of the substrate 20. As yet another example, the peripheral edges 42 of the cover 40 may be heat welded directly or indirectly to the peripheral edges 22 of the substrate 20. In any event, by securing the peripheral edges 42 of the cover 40 to the peripheral edges 22 of the substrate 20, the cover 40 and the substrate 20 may define an interior of the article of manufacture 10, within which the elastomeric element 30 of the article of manufacture 10 is contained.
(23) Turning now to
(24) The substrate 20′ of the article of manufacture 10′ may comprise a pliable element. Such a substrate 20′ may comprise a fabric. Any fabric suitable for the article of manufacture 10′ may be used. For example, in embodiments where the article of manufacture 10′ is a weighted blanket, the substrate 20′ may comprise a fabric that imparts a surface of the weighted blanket with one or more desired characteristics, such as a particular texture (e.g., softness to the touch, etc.), cooling properties (e.g., moisture wicking, ventilation or breathability, etc.), or the like. In some embodiments, the fabric may substantially lack stretchability; a fabric that substantially lacks stretchability may stretch due to a weave of the fabric, but lack stretchable fibers. In other embodiments, the fabric may be stretchable. Without limitation, a stretchable fabric may comprise a two-way stretch fabric or a four-way stretch fabric that may be stretched to its full extent without causing the elastomeric element 30′ to delaminate from the substrate 20′.
(25) The adhesion layer 34′ of the elastomeric element 30′ of the article of manufacture 10′ may comprise various spaced apart adhesion elements 35′. The adhesion elements 35′ may be secured to the substrate 20′ of the article of manufacture 10′. For example, the adhesion elements 35′ may be adhered to the substrate 20′. The material from which the adhesion elements 35′ are defined may adhere to the substrate 20′ (e.g., adhesively to a surface of the substrate 20′, by impregnating voids in the substrate 20′ (e.g., engagement voids formed in the substrate 20′, voids between fibers that define the substrate 20′, voids within fibers that define the substrate 20′, etc.), by a combination of adhesion and impregnation, etc.). Alternatively, a separate adhesive (e.g., an adhesive film, an adhesive pattern, etc., applied to the substrate 20′) may secure the adhesion elements 35′ of the adhesion layer 34′ to the substrate 20′.
(26) Each adhesion element 35′ may comprise a continuous elongated element that overlaps itself and/or portions of one or more other adhesion elements 35′. For example, an elongated element of an adhesion element 35′ may follow a winding path (e.g., an elongated, interconnected series of partially superimposed loops; a meandering path, a path resembling a wave, etc.) over at least a portion of the substrate 20′, over another portion of the same adhesion element 35′, and/or over another adhesion element 35′. Alternatively, each adhesion element 35′ may comprise a more solid structure, for example, a solid strip, spot, or grid of elastomeric polymer.
(27) The adhesion layer 34′ may cover only a portion of the area of the substrate 20′ over which the adhesion layer 34′ extends (e.g., substantially all of the surface of the substrate 20′, with the possible exclusion of peripheral locations of the surface, etc.). By way of example, the adhesion layer 34′ may cover, at most, one half of the area of the substrate 20′ over which the adhesion layer 34′ extends. As another example, the adhesion layer 34′ may cover, at most, one fourth of the area of the substrate 20′ over which the adhesion layer 34′ extends. In still another example, the adhesion layer 34′ may cover, at most, one tenth of the area of the substrate 20′ over which the adhesion layer 34′ extends.
(28)
(29) In other embodiments, the adhesion layer 34′ may substantially cover the area of the substrate 20′ over which it extends; i.e., the adhesion layer 34′ may comprise a confluent layer.
(30) Any of a variety of suitable materials may be used to define the adhesion layer 34′. In some embodiments, the adhesion layer 34′ may be defined from an elastomeric polymer. More specifically, the elastomeric polymer may comprise a material that will adhere well to both the substrate 20′ and the functional layer 36′. In embodiments where the substrate 20′ is stretchable, a stretchability and a resilience of the elastomeric polymer may match or exceed a stretchability and a resilience of the substrate 20′, which may enable the substrate 20′ to be stretched to its full extent. Thus, the adhesion layer 34′ may not hinder stretching of the substrate 20′ or delaminate from the substrate 20′. By way of example, the elastomeric polymer may comprise an extended triblock copolymer, such as those disclosed by the '137 Patent.
(31) The functional layer 36′ of the elastomeric element 30′ may likewise cover only a portion of the area of the substrate 20′ over which the functional layer 36′ extends. In embodiments where the adhesion layer 34′ and the functional layer 36′ both have configurations that cover only a portion of the area of the substrate 20′ over which they extend, the functional layer 36′ may cover only a portion of the adhesion layer 34′ or it may be superimposed over an entirety of the adhesion layer 34′, either substantially coextensive with the adhesion layer 34′ or in a manner that extends beyond the adhesion layer 34′.
(32) Alternatively, as illustrated by
(33) In various embodiments, the solid structures 37′ of the functional layer 36′ may printed onto the adhesion layer 34′ and/or the substrate 20′. In more specific embodiments, the solid structures 37′ of the functional layer 36′ may comprise continuous elongated elements that overlap themselves and/or each other to define the voids 39′ of the functional layer 36′. For example, such a solid structure 37′ may follow a winding path (e.g., an elongated, interconnected series of partially superimposed loops 38; a meandering path, a path resembling a wave, etc.) over at least portion of the adhesion layer 34′ and/or the substrate 20, over another portion of the same solid structure 37′, and/or over another solid structure 37′.
(34) Any of a variety of suitable materials may be used to define the solid structures 37′ of the functional layer 36′ of the elastomeric element 30′. In some embodiments, the solid structures 37′ may be defined from an elastomeric polymer. The elastomeric polymer may adhere well to the substrate 20′ and have a sufficient density to impart the functional layer 36′ with a desired weight and density. In addition, the elastomeric polymer may compress under a load and then resiliently return to a relaxed state once the load is removed. The elastomeric polymer that defines the solid structures 37′ of the functional layer 36′ may comprise a different material from that used to define the adhesion layer 34′ or the same elastomeric polymer as that used to define the adhesive layer 34′. In embodiments where the substrate 20′ is stretchable, a stretchability and a resilience of the elastomeric polymer may match or exceed a stretchability and a resilience of the substrate 20′, which may enable the substrate 20′ to be stretched to its full extent. Thus, the functional layer 36′ may not hinder stretching of the substrate 20′ or delaminate from the substrate 20′. For example, the elastomeric polymer that defines the solid structures 37′ of the functional layer 36′ may comprise an extended triblock copolymer, such as those disclosed by the '137 Patent.
(35) With returned reference to
(36) In some embodiments, peripheral edges 42′ of the cover 40′ may be secured to peripheral edges 22′ of the substrate 20′. The peripheral edges 42′ of the cover 40′ may be secured directly to the peripheral edges 22′ of the substrate 20′. Alternatively, the peripheral edges 42′ of the cover 40′ and the peripheral edges 22′ of the substrate 20′ may be joined to an intervening element, such as a gusset (e.g., a strip of fabric in embodiments where the substrate 20′ and the cover 40′ comprise fabrics, etc.), a trim element (e.g., piping, another embellishment, etc.), or the like. By securing the peripheral edges 42′ of the cover 40′ to the peripheral edges 22′ of the substrate 20′, the cover 40′ and the substrate 20′ may define an interior of the article of manufacture 10′, within which the elastomeric element 30′ of the article of manufacture 10′ is contained.
(37)
(38) In addition, the weighted blanket/article of manufacture 10′ includes a further layer 50′, which may comprise a base layer, adjacent to (e.g., beneath, as shown in

(41) An extruder 74 of the manufacturing system 70 may then heat the elastomeric polymer 60 to a temperature that liquefies the elastomeric polymer 60. In embodiments where the elastomeric polymer 60 comprises an oil extended SBS or SEBS copolymer, as disclosed by the '138 Patent, the elastomeric polymer 60 may be heated to a temperature of about 450° F. (about 230° C.) to about 480° F. (250° C.).
(42) Once the elastomeric polymer 60 has been heated, the extruder 74 may then force the elastomeric polymer 60 into and through an extruder arm 76 and out of nozzles 78 that communicate with the extruder arm 76. The nozzles 78 may be spaced apart along the length of the extruder arm 76. In some embodiments, the nozzles 78 may be spaced equidistantly apart from each other. While
(43) As the liquefied elastomeric polymer 60′ is forced out of the nozzles 78, it may be applied to a substrate 20′. For example, as shown in

Similar effects may be achieved by moving the extruder arm 76 (e.g., back and forth along the second axis, over a small circular path, etc.) as the liquefied elastomeric polymer 62′ exits the nozzles 78.
