1. A potty training device comprising: an enclosure of generally oval shape having an open end and a closed end, adapted to fit around a toilet seat, having two orifices aligned over each other and concentric to the toilet seat; a multiplicity of first fastening means positioned around the perimeter of the orifices; a multiplicity of first straps having a first fastening means positioned at each end portion of each first strap for connecting each first strap through the orifices to the first fastening means positioned around the perimeter of the orifices; a sleeve connected to the open end and adapted to receive a chord; the chord being positioned within the sleeve and having its end portions protruding from the enclosure; and a second fastening means positioned on at least one of the end portions of the chord for securing the enclosure to a toilet.
2. The potty training device of claim 1, wherein the orifices are small enough to permit a child to seat over them without falling through.
3. The potty training device of claim 2, wherein the enclosure is formed by a top layer, a bottom layer, and at least one resilient band connecting each other at their outer edge portions except for the open end.
4. The potty training device of claim 3, wherein the top layer and bottom layer are made of lightweight, easy-to-wash, and quick-drying material.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An easy-open end having a polyester film applied, via a primer, onto the inner surface of the end of an aluminum base sheet forming a surface-treating layer that contains a zirconium compound andor a titanium compound and an organic compound, wherein said primer contains a polyester resin that contains not less than 30% by weight of a carboxyl group-introduced polyester resin, and a phenol resin at a weight ratio of 50:50 to 85:15.
2. The easy-open end according to claim 1, wherein said carboxyl group-introduced polyester resin has not less than two carboxylic anhydride groups in a molecule thereof.
3. The easy-open end according to claim 1, wherein said carboxyl group-introduced polyester resin has an acid value of 150 to 800 meqkg.
4. The easy-open end according to claim 1, wherein said phenol resin is an m-cresol resole type phenol resin.
5. The easy-open end according to claim 1, wherein said surface-treating layer is an organicinorganic composite surface-treating layer containing the zirconium compound in an amount of 2 to 20 mgm2 calculated as zirconium atoms, the phosphorus compound in an amount of 1 to 10 mgm2 calculated as phosphorus atoms, and the organic compound in an amount of 5 to 60 mgm2 calculated as carbon atoms, said organic compound is an organic polymer having a structural unit represented by the following formula (1),
wherein \u03c6 is a benzene ring, and X is a hydrogen atom or a group Z represented by the following formula (2),
wherein R1 and R2 are hydrogen atoms, alkyl groups having 1 to 10 carbon atoms or hydroxyalkyl groups having 1 to 10 carbon atoms,
the introduction ratio of the groups Z being 0.3 to 1.0 groups per a benzene ring,
and when Xs are all hydrogen atoms, said organic polymer has an average molecular weight of 1,000 to 100,000.
6. The easy-open end according to claim 1, wherein said surface-treating layer is an organicinorganic composite surface-treating layer containing the zirconium compound andor the titanium compound in an amount of 4 to 30 mgm2 calculated as zirconium atoms andor titanium atoms, the organic phosphonic acid compound in an amount of 0.2 to 9 mgm2 calculated as phosphorus atoms, and the tannin in an amount of 2 to 90 mgm2 calculated as carbon atoms.
