Storage jar

Abstract

A storage jar, including: a jar body with an accommodating cavity for accommodating stored substances; a lid body for covering the accommodating cavity; a buckling structure for detachably connecting the jar body to the lid body; and a limiting structure arranged offset from the buckling structure in a circumferential direction of the jar body and cooperating with the buckling structure to fix the lid body on the jar body.

         2 . The storage jar according to  claim 1 , wherein the limiting structure ( 40 ) comprises a limiting member ( 41 ) and a limiting hole ( 42 ) for accommodating the limiting member ( 41 ), and the limiting hole ( 42 ) has an axis extending in a radial direction of the jar body ( 10 ). 
     
     
         3 . The storage jar according to  claim 2 , wherein the limiting member ( 41 ) has a plate form, and the limiting hole ( 42 ) extends in the circumferential direction of the jar body ( 10 ) and is strip-shaped. 
     
     
         4 . The storage jar according to  claim 2 , wherein the limiting member ( 41 ) has a plate form, and the cross sectional shape of the limiting member ( 41 ) is set to be curved and/or bent. 
     
     
         5 . The storage jar according to  claim 1 , wherein the buckling structure ( 30 ) comprises a buckling arm ( 31 ) and a buckling portion ( 32 ) engaged with each other, and the buckling arm ( 31 ) is provided with a hand-held portion ( 33 ). 
     
     
         6 . The storage jar according to  claim 5 , wherein the buckling arm ( 31 ) is provided with a first hole portion ( 35 ) for accommodating the buckling portion ( 32 ). 
     
     
         7 . The storage jar according to  claim 6 , wherein the buckling portion ( 32 ) is provided with an anti-disengaging convex portion ( 34 ) or an anti-disengaging concave portion. 
     
     
         8 . The storage jar according to  claim 5 , wherein the buckling portion ( 32 ) has a plate form, and the cross sectional shape of the buckling portion ( 32 ) is set to be curved and/or bent. 
     
     
         9 . The storage jar according to  claim 1 , wherein the lid body ( 20 ) is provided with a flange within the accommodating cavity, a sealing ring ( 50 ) is sleeved on an outer side of the flange, and the sealing ring ( 50 ) and the accommodating cavity fit together to form a seal. 
     
     
         10 . The storage jar according to  claim 1 , wherein the jar body ( 10 ) is provided with an end surface abutting the lid body ( 20 ), and a sealing ring ( 50 ) is provided between the end surface and the lid body ( 20 ). 
     
     
         11 . The storage jar according to  claim 1 , wherein the jar body ( 10 ) is provided with an end surface abutting the lid body ( 20 ), a first turnup ( 11 ) is provided at an edge of the end surface, and the lid body ( 20 ) is accommodated on an inner side of the first turnup ( 11 ). 
     
     
         12 . The storage jar according to  claim 11 , wherein the buckling structure ( 30 ) and/or the limiting structure ( 40 ) are/is arranged at the first turnup ( 11 ). 
     
     
         13 . The storage jar according to  claim 11 , wherein the lid body ( 20 ) is provided with a second turnup ( 22 ) covering an end portion of the first turnup ( 11 ). 
     
     
         14 . The storage jar according to  claim 1 , wherein the lid body ( 20 ) is provided with a raised portion ( 21 ), and the raised portion ( 21 ) is arranged at a side of the lid body ( 20 ) facing away from the jar body ( 10 ). 
     
     
         15 . The storage jar according to  claim 1 , wherein the jar body ( 10 ) is made of a transparent plastic material.
