Abstract:
PROBLEM TO BE SOLVED: To provide a lid body with an increased commercial value by reducing the deformation of a side wall part and reducing the contact of a food material in a container body with the inside face of a lid body (when the lid body is opened, little rice, etc. is attached on the inside face of the lid body). SOLUTION: This lid body includes a base bottom part, a top face part and a side wall part joining the base bottom part and the top face part. The side wall part has a plurality of joined inclining faces with different inclination angles. The inclining face, has an inclination angle larger closer to the base bottom part and smaller closer to the top face part. The ratio of the inclining length of the adjoining inclining faces to the inclining faces is 3:7 to 7:3. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus that easily prepares a cleaning liquid, automatically controls the concentration of a cleaning liquid to prepare a cleaning liquid and smoothly functions the whole system and a method for using the apparatus in a pipe conduit cleaning apparatus using a powder detergent. SOLUTION: In a plant having a pipe conduit for mixing and processing a liquid, when the inside of the pipe conduit is cleaned by using a cleaning liquid composed of the powder detergent A in order to clean the pipe conduit, an apparatus for a cleaning liquid production process is installed separately from a plant main body and the process is divided into a high-concentration cleaning liquid preparation process and a diluted cleaning liquid C preparation process. Consequently, the detergent is uniformly dispersed, the concentration is easily adjusted and a plurality of powders are readily mixed and prepared. The automatic concentration control apparatus for a cleaning liquid is composed of a sensor such as a conductivity meter 5 etc., to be instantly and continuously used and a computer controller.
