Closure device for hinged-lid containers

Abstract

A closure having a frame, a lid and a first closing means as well as at least one second closing means, apart from the first closing means. The closing means each have a lid portion and a frame portion, the first closing means can be opened by the frame portion being manipulated and the second closing means can be opened by the lid portion being manipulated. The lid portion of the second closing means has a pressure-exerting surface and a counter-pressure surface, the lid portion can be fixed by the retaining forces such that a pivoting force acting transversely to the retaining forces can be introduced into the lid portion, via the pressure-exerting surface and counter-pressure surface, in order for the lid to be pivoted out of the closed position.

What is claimed is: 
     
         1 . A closure device ( 10 ) comprising a frame ( 20 ) defining an opening, a lid ( 30 ), which covers the opening and is pivotably coupled to the frame ( 20 ) via a pivot axis ( 6 ) arranged on a side of the frame, and a first closure means ( 40 ), and at least one second closure means ( 50 ), which is distanced from the first closure means ( 40 ), wherein the closure means ( 40 ,  50 ) serve to hold the lid in a closed position and each have a lid portion ( 41 ,  51 ) and a frame portion ( 42 ,  52 ), wherein the first closure means ( 40 ) can be opened by direct action of an opening force on the associated frame portion ( 42 ) and the second closure means ( 50 ) can be opened by direct action of an opening force on the associated lid portion ( 51 ), characterized in that the lid portion ( 51 ) of the second closure means ( 50 ) comprises a pressure surface and a counter pressure surface, wherein the pressure surface serves as a contact surface for the opening force or for a first retaining force and the counter pressure surface serves as a contact surface for a second retaining force, which is opposite the first retaining force, wherein the lid portion ( 51 ) can be fixed by the retaining forces in such a way that a pivot force acting substantially transversely to the retaining forces can be introduced into the lid portion ( 51 ) via the pressure surface and counter pressure surface in order to pivot the lid ( 30 ) out from the closed position. 
     
     
         2 . The closure device ( 10 ) according to  claim 1 , characterized in that the lid portion ( 51 ) of the second closure means ( 50 ) comprises a detent hook ( 53 ), which in a locking position engages from behind with a detent undercut ( 58 ) of the frame portion ( 52 ) of the second closure means ( 50 ). 
     
     
         3 . The closure device ( 10 ) according to  claim 2 , characterized in that the lid portion ( 51 ) of the second closure means ( 50 ) comprises a tab ( 54 ) having a front side ( 59 ) and a rear side ( 60 ), wherein the front side ( 59 ) forms the pressure surface and the rear side ( 60 ) forms the counter pressure surface, and wherein the detent hook ( 53 ) is formed integrally with the tab ( 54 ). 
     
     
         4 . The closure device ( 10 ) according to  claim 3 , characterized in that the tab ( 54 ) is connected to the lid ( 30 ) via a flexible connection piece ( 56 ), which defines a pivot axis ( 57 ) for the detent hook ( 53 ). 
     
     
         5 . The closure device ( 10 ) according to  claim 4 , characterized in that the detent hook ( 53 ) is arranged between the pivot axis ( 57 ) and the detent undercut ( 58 ). 
     
     
         6 . The closure device ( 10 ) according to  claim 1 , characterized in that the first closure means ( 40 ) and the second closure means ( 50 ) are arranged on an arrangement side ( 11 ) of the closure device ( 10 ). 
     
     
         7 . The closure device ( 10 ) according to  claim 6 , characterized in that the arrangement side ( 11 ) is arranged opposite the pivot axis ( 6 ). 
     
     
         8 . The closure device ( 10 ) according to  claim 1 , characterized in that a distance between the first closure means ( 40 ) and the second closure means ( 50 ) is less than 15 cm. 
     
     
         9 . The closure device ( 10 ) according to  claim 1 , characterized in that the lid ( 30 ) and the frame ( 20 ) of the closure device ( 10 ) are formed as a one-part component. 
     
     
         10 . The closure device ( 10 ) according to  claim 1 , characterized in that the frame ( 20 ) and the lid ( 30 ) are pivotably interconnected by a living hinge. 
     
     
         11 . The closure device ( 10 ) according to  claim 1 , characterized in that a stable open position of the lid ( 30 ) is defined by the living hinge. 
     
     
         12 . A container having a closure device according to  claim 1 .
