LUNCH BOX WITH SLIPPAGE PREVENTIVE DENT (NON SLIP LUNCH BOX)

摘要

PROBLEM TO BE SOLVED: To solve problems that there is a risk of dropping of a cup or tray put on a lunch box while carrying the lunch box for having a lunch, etc. when the cup or tray must be held by one hand to open/close a door, etc. on the way or when a balance is lost in ascending/descending stairs because the surface of a lunch box lid is slippery, wherein there are concerns about the durability of a slippage preventive material in repeatedly washing the lunch box and about mixing of the slippage preventive material into food when the slippage preventive material applied or bonded to the lunch box starts to come off, and wherein setting of a storage place before or after carrying the lunch box and periodical hygiene management are necessary and inconvenient.;SOLUTION: A dent 1 is formed in each lunch box lid of a normal lunch box or a set of large and small lunch boxes. Grooves for air discharge are further applied on the dented surface of the lid of the normal lunch box or a lid of a small lunch box of a two-staged lunch box for improving slippage preventive effects. With this structure, safety of stacked articles not easily slipping off can be secured, and by making all the bottom corners of the dent 1 round faces, the cleaning effect in washing is improved and consideration is given to a hygiene aspect.;COPYRIGHT: (C)2013,JPO&INPIT
