Abstract

A massage ball having a plurality of adjacent foam layers including at least one first density foam layer, at least one second density foam layer and at least one third density foam layer, and a glue layer between each adjacent foam layer thereby adhering together the plurality of foam layers. A density of the first density foam layer is different from a density of the second density foam layer which is different from a density of the third density foam layer. The massage ball may also include a solid core in the center thereof.

First claim

What is claimed is:

1 . A massage ball comprising:
a plurality of adjacent foam layers including at least one first density foam layer, at least one second density foam layer and at least one third density foam layer; a glue layer between each adjacent foam layer thereby adhering together said plurality of foam layers; wherein a density of the first density foam layer is different from a density of the second density foam layer which is different from a density of the third density foam layer.

2 . The massage ball according to claim 1 , wherein a hardness of the at least one first density foam layer is greater than a hardness of the at least one second density foam layer.

3 . The massage ball according to claim 2 , wherein the hardness of the at least one second density foam layer is greater than a hardness of the at least one third density foam layer.

4 . The massage ball according to claim 3 , further comprising at least one fourth density foam layer, the hardness of the at least one third density foam layer being greater than a hardness of the at least one fourth density foam layer.

5 . The massage ball according to claim 4 , wherein the at least one first density foam layer includes two first density foam layers defining opposed end surfaces of the massage ball.

6 . The massage ball according to claim 5 , wherein the at least one second density foam layer includes two second density foam layers disposed adjacent the first density foam layers.

7 . The massage ball according to claim 6 , wherein the at least one third density foam layer includes three third density foam layers and the at least one fourth density foam layer includes two fourth density foam layers, the third density foam layers and the fourth density foam layers forming alternating central layers in the massage ball.

8 . The massage ball according to claim 1 , further comprising a solid core within a center of the massage ball.

9 . The massage ball according to claim 5 , wherein said solid core is made from a rubber material.

10 . The massage ball according to claim 1 , wherein said glue layers define a rib structure between said plurality of foam layers.

11 . The massage ball according to claim 1 , wherein the massage ball is spherical.
