Abstract
Official abstract text for this publication.
A tank made of resin provided with a barrier layer, which prevents the barrier layer from rolling up and has improved durability. In a tank made of resin that includes a barrier layer provided on an inner surface of a tank body made of resin, an opening part is provided in the barrier layer, a thick part projecting toward an inside or an outside of the tank body is provided in a resin layer at an outer peripheral part of the opening part, and the barrier layer and a casting flange part at a base of an oil filling port tubular part are molded with the resin of the tank body in a state in which the casting flange part is located at the thick part.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tank made of resin, comprising: a barrier layer provided on an inner surface of a tank body made of resin, wherein an opening part is provided in the barrier layer, a thick part projecting toward an inside or an outside of the tank body is provided in a resin layer at an outer peripheral part of the opening part, and the barrier layer and a casting flange part at a base of an oil filling port tubular part are molded with the resin of the tank body in a state in which a distal end of an end edge of the opening part in the barrier layer is located at the thick part and is located inside a recessed groove that is in an annular shape and that is formed in a lower surface of the casting flange part, wherein the end edge of the opening part in the barrier layer has a cylindrical shape or a conical shape with a section bent with a curvature, and a guide wall, along which an oil filling nozzle is guided, is provided at a lower portion of the oil filling port tubular part, and wherein the end edge is located outside the guide wall in a radial direction. 2. The tank made of resin according to claim 1 , comprising: a mouth fitting member provided at the oil filling port tubular part, and a roughly worked surface provided on an outer peripheral surface of the mouth fitting member, wherein the mouth fitting member and the oil filling port tubular part are integrated with a resin of the oil filling port tubular part bonded to the roughly worked surface. 3. The tank made of resin according to claim 1 , wherein a mouth fitting member is provided at the oil filling port tubular part, and the mouth fitting member includes an attachment part that is a lid member for an oil filling port and the guide wall located at the lower portion of the oil filling port tubular part. 4. The tank made of resin according to claim 1 , wherein a mouth fitting member is provided at the oil filling port tubular part, and a lower portion of the mouth fitting member includes a restricting part configured to restrict entrance of the oil filling nozzle at a location extending further downward than the barrier layer. 5. The tank made of resin according to claim 2 , wherein a mouth fitting member is provided at the oil filling port tubular part, and the mouth fitting member includes an attachment part that is a lid member for an oil filling port and the guide wall located at the lower portion of the oil filling port tubular part. 6. The tank made of resin according to claim 2 , wherein a mouth fitting member is provided at the oil filling port tubular part, and a lower portion of the mouth fitting member includes a restricting part configured to restrict entrance of an oil filling nozzle at a location extending further downward than the barrier layer.
