Cosmetics Box Having Damping Effect When Being Opened

Abstract

A cosmetics box includes a housing, a receiving tray secured in the housing, a lid pivotally mounted on the housing to cover the receiving tray, and two pivot mechanisms mounted between the lid and the receiving tray so that the lid is pivotally connected with the receiving tray. Thus, when the lid is pivoted relative to the housing, the rotation of the lid is damped and braked by the pivot mechanisms to largely reduce the rotation speed of the lid relative to the housing, thereby preventing the lid from violently hitting the housing and the receiving tray due to an excessive force and a higher rotation speed, and thereby protecting the articles contained in the receiving tray.

1 . A cosmetics box, comprising:
 a housing;   a receiving tray secured in the housing;   a lid pivotally mounted on the housing to cover the receiving tray; and   two pivot mechanisms mounted between the lid and the receiving tray so that the lid is pivotally connected with the receiving tray;   wherein each of the pivot mechanisms includes:   a main body;   an operation member rotatably mounted in the main body;   a damping member movably mounted in the main body and pressing the operation member to damp rotation of the operation member;   a stop member mounted on the main body; and   an elastic member mounted in the main body and biased between the stop member and the damping member to press the damping member toward the operation member;   the main body of each of the pivot mechanisms has a first end formed with a polygonal limit hole and a second end formed with a passage having a size smaller than that of the limit hole;   the operation member of each of the pivot mechanisms has a first end formed with a rotation disk rotatably mounted in the limit hole of the main body and a second end formed with a polygonal driven post extending through and protruding outward from the passage of the main body;   the rotation disk of the operation member of each of the pivot mechanisms has a side formed with two opposite first abutting blocks and two opposite first locking grooves disposed between the two first abutting blocks;   the rotation disk of the operation member of each of the pivot mechanisms has two opposite first oblique guide faces each extending from a respective one of the two first abutting blocks to a respective one of the first locking grooves;   the damping member of each of the pivot mechanisms has a side formed with two opposite second abutting blocks and two opposite second locking grooves disposed between the two second abutting blocks;   the damping member of each of the pivot mechanisms has two opposite second oblique guide faces each extending from a respective one of the two second abutting blocks to a respective one of the second locking grooves;   each of the two second abutting blocks of the damping member is detachably locked in a respective one of the first locking grooves of the operation member at a normal state and is movable to press a respective one of the two first abutting blocks of the operation member;   each of the two first abutting blocks of the operation member is detachably locked in a respective one of the two second locking grooves of the damping member at a normal state;   the stop member of each of the pivot mechanisms is inserted into the limit hole of the main body.   
     
     
         2 . The cosmetics box of  claim 1 , wherein
 the main body of each of the pivot mechanisms has an outer wall formed with a polygonal shank;   the damping member of each of the pivot mechanisms has a periphery formed with a polygonal limit portion movably mounted in the limit hole of the main body;   the housing has an inner portion formed with a mounting space to receive the receiving tray;   the housing has a side formed with an elongate opening;   the opening of the housing has two opposite sides each formed with a stop wall abutting the stop member of a respective one of the pivot mechanisms;   the receiving tray has an inner portion formed with at least one receiving chamber;   the receiving tray has a side formed with two spaced mounting seats to receive the pivot mechanisms respectively;   each of the mounting seats of the receiving tray is received in the opening of the housing and abuts the respective stop wall of the housing;   each of the mounting seats of the receiving tray has an inner portion formed with a polygonal locking hole locked onto the shank of the main body of a respective one of the pivot mechanisms;   the lid has a side formed with a pivot seat pivotally mounted between the mounting seats of the receiving tray;   the pivot seat of the lid has two opposite ends each formed with a polygonal driving hole locked onto the driven post of the operation member of a respective one of the pivot mechanisms.   
     
     
         3 . The cosmetics box of  claim 2 , wherein
 the driving hole of the pivot seat is aligned with the locking hole of a respective one of the mounting seats;   the driving hole of the pivot seat is deflected slightly and has a periphery that is staggered with the locking hole of the respective mounting seat through an angle;   the mounting space of the housing has a peripheral wall formed with at least one snap-fit groove;   the receiving tray has a periphery formed with at least one snap-fit block snapped into and locked in the snap-fit groove of the housing to lock the receiving tray in the mounting space of the housing.   
     
     
         4 . The cosmetics box of  claim 1 , wherein
 the main body of each of the pivot mechanisms has a periphery formed with a fixing portion;   the fixing portion of the main body is a fixing slot;   the stop member of each of the pivot mechanisms has a periphery formed with a locking portion engaging the fixing portion of the main body to lock the stop member onto the main body;   the locking portion of the stop member is a locking wedge locked in the fixing portion of the main body.   
     
     
         5 . The cosmetics box of  claim 1 , wherein
 the operation member of each of the pivot mechanisms has a central portion formed with a guide hole;   the damping member of each of the pivot mechanisms has a central portion formed with a guide rod inserted into the guide hole of the operation member;   the rotation disk of the operation member has a size greater than that of the passage of the main body so that the rotation disk of the operation member is not detached from the passage of the main body;   the limit portion of the damping member has a shape and size matching that of the limit hole of the main body so that the damping member of each of the pivot mechanisms is movable axially relative to the main body and is non-rotatable relative to the main body.   
     
     
         6 . The cosmetics box of  claim 1 , wherein
 the stop member of each of the pivot mechanisms has an inner portion formed with a receiving recess to receive the elastic member;   the operation member, the damping member and the elastic member of each of the pivot mechanisms are limited between the main body and the stop member;   the elastic member of each of the pivot mechanisms has a first end received in the receiving recess of the stop member and a second end received in the limit hole of the main body.
