Embodiment Construction

[0077] The resin container and the composite container according to the embodiment of the present invention, and the method for producing the above resin container will be described below with reference to the drawings. In addition, in each figure, the same code|symbol is attached|subjected to the same or the same structural part. In addition, the above-mentioned composite container refers to a container in which a resin inner container is filled in an outer container having a higher rigidity than the inner container, and corresponds to a double container.

[0078] 1st embodiment

[0079] exist figure 1 In , the resin barrel 101 of this embodiment is shown. Here, the resin barrel 101 corresponds to an example of a resin container. In addition, this resin container is not limited to the cylindrical shape like the resin barrel 101, For example, it may be square etc., The shape is not limited.

[0080] The resin barrel 101 is produced by blow molding a thermoplastic resin ma...

Abstract

The invention provides a resin barrel, which is manufactured by the blow moulding of thermoplastic resin.According to the invention, the accommodation object (3) is discharged out of the resin barrel (101) by a discharge hose (102) inserted into the barrel through an opening part (106b) formed on a top board (105) and the residual amount is reduced by a projection (110).The projection for reducing the residual amount formed on the bottom board (104) of the barrel projects toward the internal of the barrel.The barrel is also equipped with an inclined surface (111) arranged just below the above opening part.The inclined surface abuts against the top (102a) of the discharge hose for introducing the top toward the residual accommodation object.

Description

technical field [0001] The present invention relates to a resin container such as a resin drum made of, for example, polyethylene material, a composite container in which an inner container is filled in an outer container, and a method for manufacturing the resin container. Background technique [0002] There are resin barrels produced by blow molding using thermoplastic resin materials such as polyethylene materials, and given names such as polyethylene cylinders and plastic cylinders. Compared with steel tanks, such resin tanks are superior in chemical liquid resistance, corrosion resistance, etc., and therefore are often used as containers for accommodating chemical liquids in the semiconductor field and liquid crystal field, for example. In addition, examples of the above-mentioned chemical solutions include chemical mechanical polishing fluid, photoresist, developer, etching solution, cleaning solution, etc. in the field of semiconductors, and photoresist, color retenti...
