Abstract
Abstract A resiliently deformable toy ball which is soft and supple and provides an intriguing relaxing feeling when squeezed, and which possesses a low rebound percentage due to its resliently deformable nature. The ball has a highly plasticized PVC core which is resiliently deformable due to its highly plasticized state. The PVC core is encased in a flexible polymer shell and both the core and the flexible shell are further encased in a stretchable fabric outer cover.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
77 words
A toy ball having a soft and supple feeling and a rebound percentage of about 9%, which is directly proportional to the height from which the ball is dropped, comprising: a highly plasticized polyvinyl chloride core which resiliently deformable due to its highly plasticized state and bleeds plasticizer; a flexible polymer shell encasing said core for containing bleeding of the plasticizer from said core; and a stretchable fabric outer cover encasing said core and said flexible shell.
Claim 2
Dependent Claim
77 words
A toy ball having a soft and supple feeling and a rebound percentage of about 9%, which is directly proportional to the height from which the ball is dropped, comprising: a highly plasticized polyvinyl chloride core which resiliently deformable due to its highly plasticized state and bleeds plasticizer; a flexible polymer shell encasing said core for containing bleeding of the plasticizer from said core; and a stretchable fabric outer cover encasing said core and said flexible shell.
Claim 3
Dependent Claim
20 words
The toy ball of claim 1 wherein said core contains about 25% polyvinyl chloride and at least about 60% plasticizer.
Claim 4
Dependent Claim
25 words
The toy ball of claim 2 wherein said flexible polymer shell substantially prevents bleeding of said plasticizer from said core through said fabric outer cover.
Claim 5
Dependent Claim
28 words
The toy ball of claim 3 wherein said polymer shell includes about 80% latex, 14% kaolin and 4% zinc oxide, said shell being substantially impervious to said plasticizer.
Claim 6
Dependent Claim
21 words
The toy ball of claim 2 wherein said core further contains about 14% stabilizer and about 1% of a fragrance compound.
Claim 7
Dependent Claim
20 words
The toy ball of claim 1 wherein said stretchable fabric outer cover is about 80% nylon and about 20% spandex.
Claim 8
Dependent Claim
71 words
The toy ball of claim 1 wherein said ball has a weight W 1 , and has a first diameter D 1 when no external forces are exerted on said ball and a second diameter D 2 when the force of a test weight W 2 is exerted on said ball for about 2 seconds, and D 2 is about 1/2D 1 , when W 2 is about 12.5W 1 .
Claim 9
Dependent Claim
33 words
The toy ball of claim 7 wherein W 1 is about 150 grams, W 2 is about 1850 grams, D 1 is between about 60-67 mm, and D 2 is about 33 mm.
Claim 10
Dependent Claim
75 words
A toy ball having a soft and supple feeling and a rebound percentage which is directly proportional to the height from which the ball is dropped, comprising: a highly plasticized polyvinyl chloride core which is resiliently deformable due to its highly plasticized state and bleeds plasticizer; a flexible polymer shell encasing said core for containing bleeding of the plasticizer from said core; and a stretchable fabric outer cover encasing said core and said flexible shell.
Claim 11
Dependent Claim
75 words
A toy ball having a soft and supple feeling and a rebound percentage which is directly proportional to the height from which the ball is dropped, comprising: a highly plasticized polyvinyl chloride core which is resiliently deformable due to its highly plasticized state and bleeds plasticizer; a flexible polymer shell encasing said core for containing bleeding of the plasticizer from said core; and a stretchable fabric outer cover encasing said core and said flexible shell.
Claim 12
Dependent Claim
131 words
A toy ball having a soft and supple feeling and a rebound percentage which is directly proportional to the height from which the ball is dropped, comprising: a highly plasticized polyvinyl chloride core which is resiliently deformable due to its highly plasticized state and bleeds plasticizer; a flexible polymer shell encasing said core for containing bleeding of the plasticizer from said core; a stretchable fabric outer cover encasing said core and said flexible shell; and said ball has a weight of about 150 grams, and has a first diameter of between about 60-67 mm when no external forces are exerted on said ball and a second diameter of about 33 mm when the force of a test weight of about 1850 grams is exerted on said ball for about 2 seconds.
Claim 13
Dependent Claim
131 words
