Container with lid

Abstract

A container with lid, in particular a bucket with lid, has a container wall, a container bottom and a container opening, which is defined by an upper edge of the container, and structure in the upper part of the container for fixing the lid or a peripheral, inwardly protruding frame, to which the lid can be detachably locked. The container wall has on its upper part an outwardly protruding shoulder, such that containers can be stacked one into the other. To provide a container with lid which can be easily manufactured at low cost, if possible also by an in-mold labeling process, at least one radially outwardly and/or axially projecting protrusion ( 16, 30 ) is provided on a shoulder ( 12 ) on the outside thereof, wherein (a) an upper container rim ( 5 ) is provided with at least one recess ( 35 ), which when the containers are stacked one into the other is engaged by the at least one protrusion ( 30 ) of the shoulder ( 12 ) while preventing twisting, and/or wherein (b) the at least one axially projecting protrusion ( 16 ) extends at least around a part of the container ( 1 ) and radially outwardly engages behind an upper rim portion ( 5, 7 ) of a respective lower one of the stacked containers.

1 . A container with lid, the container comprising a container wall, a container bottom, a container opening defined by an upper edge of the container, a lid, and (a) fixing means in an upper part of the container wall for fixing the lid or (b) a peripheral, inwardly protruding frame, to which the lid can be detachably locked, wherein the container wall includes an outwardly protruding shoulder on its upper part, and wherein plural containers can be stacked one into another,
 wherein externally on the shoulder at least one protrusion is provided which projects radially and/or axially outwardly from the container wall, and wherein:
 (1) an upper rim of the container is provided with at least one recess which, when plural containers are stacked one into another, is engaged by the at least one protrusion of the shoulder to form an anti-twist device, or 
 (2) the at least one protrusion projects axially at least around a part of the container and radially outwardly engages behind an upper rim portion of a respective lower one of stacked containers, or 
 (3) an upper rim of the container is provided with at least one recess which, when plural containers are stacked one into another, is engaged by the at least one protrusion of the shoulder to form an anti-twist device and the at least one protrusion projects axially at least around a part of the container and radially outwardly engages behind an upper rim portion of a respective lower one of stacked containers. 
   
   
   
       2 . The container according to  claim 1 , wherein the recess of the upper rim of the container is arranged on an upper edge of the container and a container rim portion engaged by the axially projecting protrusion is the upper edge of the container. 
   
   
       3 . The container according to  claim 1 , wherein an axial extension of one or more components of the group consisting of (i) the recess of the container rim, (ii) the anti-twist protrusions and (iii) the axially projecting protrusions is smaller than or equal to eight times a thickness of the container wall. 
   
   
       4 . The container according to  claim 1 , wherein a circumferential extension of the recess of the container rim or of the anti-twist protrusions or of the recess and the protrusions is smaller than or equal to eight times a thickness of the container wall. 
   
   
       5 . The container according to  claim 1 , wherein a radial extension of the shoulder is smaller than or equal to four times a thickness of the container wall. 
   
   
       6 . The container according to  claim 1 , wherein the container includes a handle supported on the container wall by articulation links and the recesses and the anti-twist protrusions are arranged in a region of the articulation links. 
   
   
       7 . The container according to  claim 1 , wherein the at least one of the radially projecting anti-twist protrusions is molded to the at least one protrusion which engages behind a container rim portion. 
   
   
       8 . The container according to  claim 1 , wherein the container is so constructed that, when plural containers are stacked one into another, a bottom side of the shoulder of an upper one of the containers on an external side of the container is seated on an upper edge of a lower one of the containers. 
   
   
       9 . The container according to  claim 1 , wherein the upper part of the container wall includes a radially inwardly or outwardly directed constriction formed by a fin all around the upper part, wherein the fin is set back from an outside or an inside of the container. 
   
   
       10 . The container according to  claim 9 , wherein the at least one axial protrusion engages behind the fin externally. 
   
   
       11 . The container according to  claim 9 , wherein fixing means or the frame that fixes the lid is formed on the fin. 
   
   
       12 . The container according to  claim 11 , wherein the fixing means are situated on a radial outside of the fin. 
   
   
       13 . The container according to  claim 1 , wherein the container wall above the shoulder increases in its thickness towards the upper edge of the container. 
   
   
       14 . The container according to  claim 1 , wherein the container is a bucket with a handle.
