Abstract

A compression shirt operable to apply compression to the torso of a wearer. The compression shirt broadly includes a knitted tubular fabric receptacle to be received on the torso of the wearer. The receptacle is knitted of core-spun yarn. The receptacle is generally undersized in an unstretched condition relative to the torso, such that the receptacle is resiliently stretched when the shirt is donned to thereby apply a compressive force to the torso. The receptacle includes integrally knitted front and back sections that cooperatively form a pair of spaced apart shoulder caps. The receptacle includes a neck opening and a pair of arm openings.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A compression shirt operable to apply compression to the torso of a wearer, said compression shirt comprising:
 a knitted tubular fabric receptacle to be received on the torso of the wearer,   said receptacle being knitted of core-spun yarn,   said receptacle being generally undersized in an unstretched condition relative to the torso, such that the receptacle is resiliently stretched when the shirt is donned to thereby apply a compressive force to the torso,   said receptacle including integrally knitted front and back sections that cooperatively present opposite receptacle side margins, with the front and back sections being seamlessly joined along the receptacle side margins,   said front and back sections cooperatively defining an open lower receptacle margin,   said front and back sections cooperatively forming a pair of spaced apart shoulder caps spaced from the lower receptacle margin,   said receptacle including a neck opening located between the shoulder caps, with the neck opening configured to receive the neck of the wearer,   said receptacle including a pair of arm openings, each being positioned laterally outside a respective one of the shoulder caps and configured to receive one of the arms of the wearer.   
     
     
         2 . The compression shirt as claimed in  claim 1 ,
 said receptacle being formed of knitted courses,   said receptacle including a plurality of laid-in elastic threads that are laid into spaced apart ones of the courses.   
     
     
         3 . The compression shirt as claimed in  claim 2 ,
 said elastic threads being laid into every fourth course.   
     
     
         4 . The compression shirt as claimed in  claim 2 ,
 said receptacle being formed of a 1×1 rib-knit stitch pattern.   
     
     
         5 . The compression shirt as claimed in  claim 1 ,
 said shoulder caps including opposite cap portions defined by the front and back sections, respectively,   said cap portions of each cap being sewn together along a cap seam.   
     
     
         6 . The compression shirt as claimed in  claim 5 ,
 said receptacle being devoid of seams except for the cap seams.   
     
     
         7 . The compression shirt as claimed in  claim 6 ,
 said cap seams defining an upper receptacle margin opposite the lower receptacle margin.   
     
     
         8 . The compression shirt as claimed in  claim 7 ,
 each of said cap seams being formed by a line of overlock stitching.   
     
     
         9 . The compression shirt as claimed in  claim 8 ,
 said opposite cap portions of each shoulder cap presenting edges, with the cap portions of each shoulder cap being sewn together while overlying one another and having the edges aligned.   
     
     
         10 . The compression shirt as claimed in  claim 9 ,
 said line of overlock stitching being cooperatively formed by a looper thread and a needle thread.   
     
     
         11 . The compression shirt as claimed in  claim 10 ,
 said receptacle presenting interior and exterior surfaces, said looper thread being sewn along the exterior surface and said needle thread being sewn along the interior surface.   
     
     
         12 . The compression shirt as claimed in  claim 11 ,
 said looper thread being about 280 denier and said needle thread being about 100 denier.   
     
     
         13 . The compression shirt as claimed in  claim 12 ,
 said looper thread being sewn with a stitch count of 26 stitches per inch and said needle thread being sewn with a stitch count of 24 stitches per inch.   
     
     
         14 . The compression shirt as claimed in  claim 10 ,
 said looper thread being about 280 denier and said needle thread being about 100 denier.   
     
     
         15 . The compression shirt as claimed in  claim 14 ,
 said looper thread being sewn with a stitch count of 26 stitches per inch and said needle thread being sewn with a stitch count of 24 stitches per inch.   
     
     
         16 . The compression shirt as claimed in  claim 9 ,
 said shirt presenting interior and exterior surfaces, said line of overlock stitching being cooperatively formed by an exterior thread sewn along the exterior surface and an interior thread sewn along the interior surface.   
     
     
         17 . The compression shirt as claimed in  claim 16 ,
 said exterior thread being about 280 denier and said interior thread being about 100 denier.   
     
     
         18 . The compression shirt as claimed in  claim 17 ,
 said exterior thread being sewn with a stitch count of 26 stitches per inch and said interior thread being sewn with a stitch count of 24 stitches per inch.   
     
     
         19 . The compression shirt as claimed in  claim 1 ,
 said core-spun yarn including a pre-tensioned elastomeric core and a twisted fiber sheath.   
     
     
         20 . The compression shirt as claimed in  claim 19 ,
 said elastomeric core comprising spandex fiber,   said sheath including non-elastomeric fibers wound about the elastomeric core,   said non-elastomeric fibers comprising a textured polyester yarn.   
     
     
         21 . The compression shirt as claimed in  claim 1 ,

         22 . The compression shirt as claimed in  claim 1 ,
 said receptacle providing a measured compression determined for a designated stretched circumference of the receptacle greater than a relaxed circumference of the receptacle.   
     
     
         23 . The compression shirt as claimed in claim  77 ,
 said measured compression ranging from about 10 mmHg to about 20 mmHg.   
     
     
         24 . The compression shirt as claimed in  claim 23 ,
 said measured compression ranging from about 15 mmHg to about 20 mmHg when the stretched circumference is about 50% greater than the relaxed circumference.   
     
     
         25 . The compression shirt as claimed in  claim 24 ,
 said measured compression ranging from about 10 mmHg to about 15 mmHg when the stretched circumference is about 25% greater than the relaxed circumference.   
     
     
         26 . The compression shirt as claimed in  claim 1 ,
 said front and back sections each having a downwardly projecting recess extending between the shoulder caps,   said recesses cooperatively defining the neck opening.   
     
     
         27 . The compression shirt as claimed in  claim 26 ,
 each of said recesses being semicircular in shape.
