摘要

#CMT# #/CMT# The cover has a slot, which is provided in a lower surface of the cover, for separating the cover into parts (30A, 30B). The part (30B) is rigidly connected to an upper opening of a cubic container (40). The part (30A) of the cover is pivoted towards the top and the bottom along the slot. A projection (34A) and complimentary notch (34B) are situated on opposite sides of the parts (30A, 30B), respectively, along the slot. The projection is engaged in the notch, for maintaining the part (30A) of the cover in an opening position, when the part (30A) is pivoted in an opening direction. #CMT#USE : #/CMT# Used for airtight closing of an upper opening of a cubic container (claimed). #CMT#ADVANTAGE : #/CMT# The parts of the cover allow to close the container in a secure manner when the cover closes the container. The projection is maintained in the slot such that one of the parts of the cover is maintained in the opening position in an automatic manner, thus allowing to access the interior of the container without the need for removing the cover, and hence maintaining the airtightness of the container when the cover is placed in a closed position. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a cubic container`s upper opening airtight closing cover. 30 : Cubic container`s upper opening airtight closing cover 30A, 30B : Cubic container`s upper opening airtight closing cover`s parts 34A : Projection 34B : Notch 40 : Cubic container 41A, 41B : Assembling elements.
