Sealable container arrangement

Abstract

A closable container arrangement includes a container, which includes a container material and has a container longitudinal axis and a container connecting element, a lid which includes a lid material, a sealing element, which includes a sealing material, for sealing the lid on the container, the sealing material includes a hardness which is less than the hardness of the container material and/or is less than the hardness of the lid material.

What is claimed is: 
     
         1 . A container arrangement, comprising:
 a container body;   a lid connectable to the container body for placing the container arrangement in a closed state; and   a sealing element, the lid comprising a circumferential groove configured to receive the sealing element in a captive manner, the groove being at least partially defined by an inner side flank, the container body having an end portion configured to contact the sealing element inside the groove when the container arrangement is in the closed state, and the container body being further configured to be spaced apart from the inner side flank when inside the groove and the container arrangement is in the closed state.   
     
     
         2 . The container arrangement in accordance with  claim 1 , further comprising:
 a displaceable bottom, wherein the container body has a container longitudinal axis, the displaceable bottom being arranged to sealably contact an inner wall of the container body and the displaceable bottom being configured to be movable along the container longitudinal axis.   
     
     
         3 . The container arrangement in accordance with  claim 1 , wherein the container body has a container longitudinal axis, wherein the inner side flank of the groove is inclined relative to the container longitudinal axis. 
     
     
         4 . The container arrangement in accordance with  claim 1 , wherein the end portion of the container body decreases in thickness towards an open end of the container body. 
     
     
         5 . The container arrangement in accordance with  claim 1 , wherein the end portion of the container body has an end face and an inner surface, the end face being configured to contact the sealing element when the container arrangement is in the closed state. 
     
     
         6 . The container arrangement in accordance with  claim 5 , wherein the sealing element is compressed by the end face of the end portion of the container body when the container arrangement is in the closed state. 
     
     
         7 . The container arrangement in accordance with  claim 5 , wherein the inner surface of the end portion of the container body is chamfered. 
     
     
         8 . The container arrangement in accordance with  claim 5 , wherein a radial gap separates the inner surface of the end portion of the container body and the inner side flank of the groove when the container arrangement is in the closed state, wherein the sealing element is reachable by fluid inside the container body via the gap when the container arrangement is in the closed state. 
     
     
         9 . The container arrangement in accordance with  claim 1 , wherein the groove is further defined by an outer side flank and the inner side flank extends further in the container longitudinal direction than the outer side flank. 
     
     
         10 . The container arrangement in accordance with  claim 1 , wherein part of the end portion is inside the groove when the container arrangement is in the closed state, and a thickness of the part of the end portion inside the groove is less than a width of the groove. 
     
     
         11 . The container arrangement in accordance with  claim 10 , wherein the part of the end portion inside the groove contacts only the sealing element and the part of the end portion inside the groove does not contact the lid. 
     
     
         12 . The container arrangement in accordance with  claim 1 , wherein the lid comprises a collar with a lid connecting element, wherein an outside of the container body and the collar of the lid comprise complementary threads to allow threading of the lid to place the container arrangement in the closed state. 
     
     
         13 . The container arrangement in accordance with  claim 12 , wherein direct contact between the container and the lid when the container arrangement is in the closed state is provided by only the complementary threads. 
     
     
         14 . The container arrangement in accordance with  claim 1 , wherein the sealing element is an O-ring. 
     
     
         15 . The container arrangement in accordance with  claim 1 , wherein the sealing element is a flat sealing ring. 
     
     
         16 . The container arrangement in accordance with  claim 1 , wherein an outside surface of the collar comprises gripping grooves to facilitate placing the container arrangement into the closed state and opening of the container arrangement from the closed state. 
     
     
         17 . The container arrangement in accordance with  claim 1 , wherein the lid comprises a central spout. 
     
     
         18 . The container arrangement in accordance with  claim 17 , further comprising a cap, wherein the central spout comprises an external thread, the cap comprising internal threads for complementarily engaging the external threads on the central spout. 
     
     
         19 . A container arrangement, comprising:
 a container body; and   a lid connectable to the container body for placing the container arrangement in a closed state, the lid comprising a circumferential groove configured to receive a sealing element, the groove being at least partially defined by an inner side flank, the container body having an end portion with an end face and a chamfered inner surface configured to be spaced apart from the inner side flank when the container arrangement is in the closed state.   
     
     
         20 . The container arrangement in accordance with  claim 19 , further comprising a displaceable bottom, the container body having a container longitudinal axis, the displaceable bottom being arranged to sealably contact an inner wall of the container body and the displaceable bottom being configured to be movable along the container longitudinal axis.
