Abstract
Abstract A teat dilator for insertion into the canal opening in a cow''s teat and characterized by a multi-sided frame of more than two members joined together; the frame providing a cavity which may be used for carrying a medicament into the canal and the members forming the frame being made of resilient plastic material so that the dilator will deform on insertion into the opening but expand again after passing through the opening to support and separate the canal walls, the dilator being adaptable to fit into and be useful with canals of varying length.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
193 words
A teat dilator adapted to be inserted into a canal opening of a cow''s teat and comprising a multisided, flexible, resilient, elongated open frame having four members joined together to form the frame, said frame being open at opposed sides providing an opening adapted to receive a medicament said members being formed of resilient plastic material, a first set of two members being joined together to provide an elongated nose portion for insertion into the canal opening, said first two members extending outwardly from said nose portion and connected at their most outwardly expanse to a second set of two members to form said frame, said second set being joined together at their ends away from the connection to said first set to provide a stop means and limit the extent of insertion of said frame into said canal, said frame members being spaced widest apart at the connection at the first set of members to the second set of members and its members being deformable inwardly on entering the canal opening whereby the deformed dilator may be gradually inserted therein and may expand and adjust to conform to various size teat openings.
Claim 2
Dependent Claim

A teat dilator adapted to be inserted into a canal opening of a cow''s teat and comprising a multisided, flexible, resilient, elongated open frame having four members joined together to form the frame, said frame being open at opposed sides providing an opening adapted to receive a medicament said members being formed of resilient plastic material, a first set of two members being joined together to provide an elongated nose portion for insertion into the canal opening, said first two members extending outwardly from said nose portion and connected at their most outwardly expanse to a second set of two members to form said frame, said second set being joined together at their ends away from the connection to said first set to provide a stop means and limit the extent of insertion of said frame into said canal, said frame members being spaced widest apart at the connection at the first set of members to the second set of members and its members being deformable inwardly on entering the canal opening whereby the deformed dilator may be gradually inserted therein and may expand and adjust to conform to various size teat openings.
Claim 3
Dependent Claim
52 words
A teat dilator as defined in claim 1 wherein shoulder portions are provided on the two members forming the nose, the shoulders being adjacent to the points where the two members are joined to the second set of members, said shoulders adapted to assist holding the dilator in place in the canal.
