Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
75 words
A method of manufacturing a bath sponge, comprising: stretching a plurality of tubes made of diamond-mesh resilient synthetic netting, in a direction transverse to a longitudinal axis of the tubes; binding all of the stretched tubes together near a common center of all of the stretched tubes; and releasing all of the tubes from their stretched condition, whereby the tubes through their resiliency rebound into a rounded sponge shape around the binding of the tubes.
Claim 2
Independent Claim
75 words
A method of manufacturing a bath sponge, comprising: stretching a plurality of tubes made of diamond-mesh resilient synthetic netting, in a direction transverse to a longitudinal axis of the tubes; binding all of the stretched tubes together near a common center of all of the stretched tubes; and releasing all of the tubes from their stretched condition, whereby the tubes through their resiliency rebound into a rounded sponge shape around the binding of the tubes.
Claim 3
Dependent Claim
35 words
A method according to claim 1 including stretching each tube between a pair of supports, each tube being gathered on its respective pair of supports before all of the tubes are bound to each other.
Claim 4
Dependent Claim
19 words
A method according to claim 2 including binding all of the tubes to each other using a plastic strip.
Claim 5
Dependent Claim
16 words
A method according to claim 3 wherein each tube of netting is made of diamond-mesh polyethylene.
Claim 6
Dependent Claim
78 words
A method according to claim 4 wherein each pair of supports comprises a pair of elongated supports each having one end connected at a fixed location and an opposite free end, whereby the opposite free ends of each pair of supports can be bent toward each other for receiving a tube of netting, the tube of netting being gathered toward the fixed ends of each support pair, for stretching each tube of netting between each pair of supports.
Claim 7
Dependent Claim
79 words
A method according to claim 1 wherein each pair of supports comprises a pair of elongated pole supports each having one end connected at a fixed location and an opposite free end, whereby the opposite free ends of each pair of supports can be bent toward each other for receiving a tube of netting, the tube of netting being gathered toward the fixed ends of each support pair, for stretching each tube of netting between each pair of supports.
