Fastening assembly and articles comprising the same

Abstract

The disclosed subject matter is directed to a fastening assembly and a container system containing the same. The fastening assembly comprises a cylindrical neck member, comprising a series of convolutions axially extending around at least a portion of the external surface of the neck member and forming an interrupted helical thread of incomplete formation; a collar member configured for screw fastening with the neck member, comprising at least one rib configured for thread-engagement with the helical thread, the at least one rib forming a portion of an internal thread.

1 . A fastening assembly extending along a longitudinal axis and comprising:
 (a) a cylindrical neck member, comprising a series of convolutions axially extending around at least a portion of the external surface of the neck member and forming an interrupted helical thread of incomplete formation;   (b) a collar member configured for screw fastening with the neck member, the collar member having an inner cylindrical surface comprising at least one rib configured for thread-engagement with the helical thread, the at least one rib forming a portion of an internal thread; and   (c) wherein each convolution of the series of convolutions extends from a lead end to a brake end and wherein the brake end is spaced from the lead end forming therebetween a sliding gap constituted by the incomplete formation of the interrupted helical thread.   
     
     
         2 . A fastening assembly according to  claim 1 , wherein the sliding gap axially extends along at least a portion of the neck member parallel to the longitudinal axis. 
     
     
         3 . A fastening assembly according to  claim 2 , wherein the at least one rib is configured for slidable displacement along the gap. 
     
     
         4 . A fastening assembly according to any one of the previous claims, wherein the neck member comprises at least two radially displaced sliding gaps. 
     
     
         5 . A fastening assembly according to any one of the previous claims, wherein the brake ends parallelly extend and are axially connected by an arresting wall configured for preventing threading of the at least one rib thereover. 
     
     
         6 . A fastening assembly according to  claim 5 , wherein the arresting wall extends radially outwards from the external surface of the neck member and projects at least to a height corresponding to the height of the convolution. 
     
     
         7 . A fastening assembly according to  claim 1 , wherein the at least one rib is configured for threading through the lead end of any one of the convolutions. 
     
     
         8 . A container system having a longitudinal axis passing therethrough, comprising:
 (a) a receptacle member comprising a cylindrical neck member, comprising a series of convolutions axially extending substantially along and around at least a portion of the external surface of the neck member and forming an interrupted helical thread of incomplete formation;   (b) a closure member configured with a collar for fastening over the neck member, a collar member configured for screw fastening over the neck member, the collar member having an inner cylindrical surface comprising at least one rib configured for thread-engagement through the helical thread, the at least one rib forming a portion of the internal thread; and   (c) wherein each convolution of the series of convolutions comprises a lead end and a brake end, such that the convolution extends from the lead end to the brake end and wherein said brake end is spaced from said lead end forming a sliding gap constituted by the incomplete formation of the interrupted helical thread.   
     
     
         9 . A container system according to  claim 8 , wherein the incomplete formation is in a form of a gap radially extending between the brake end and the lead end, extending along the neck member parallel to the longitudinal axis thereof. 
     
     
         10 . A container system according to  claim 9 , wherein the rib is configured for slidable displacement along the gap. 
     
     
         11 . A container system according to any one of the previous claims, wherein the neck member comprises at least two radially displaced vertical gaps. 
     
     
         12 . A container system according to any one of the previous claims, wherein the brake ends parallelly extend and are axially connected by an arresting wall configured for preventing threading of the rib thereover. 
     
     
         13 . A container system according to  claim 12 , wherein arresting wall extends radially outwards from the external surface of the neck member and projects to a height corresponding to the height of the convolution. 
     
     
         14 . A container system according to  claim 8 , wherein the at least one rib is configured for threading through the lead end of any one of the convolutions.
