Extruded Spring Strap for Container and Packaging Applications

Abstract

An extruded spring strap that has the possibility to be folded around an axis parallel to its own axis of extrusion, creating the compression and release as of a spring. A base has a reach-in hole on its body. The lid is the base's capping object; it is designed to cover the reach-in hole. A spring strap clip allows the extension of the spring strap during the closing motion of the lid. The spring strap and the spring strap clip assembled to the lid and base. An area of hot melt fills a cavity on the spring clip ensuring proper position for the spring clip during usage and no disassembly. The extruded spring strap can store and release energy in order to displace the lid. The retention latch is the user interface on which he acts in order to have the lid pop-up.

1 . A closure system comprising an extruded spring strap in combination with a base, a lid, and a spring strap clip for creating container and packaging applications comprising:
 the extruded spring strap folded around an axis parallel to the extruded spring strap's own axis of extrusion;   the spring strap clip and spring strap having corresponding matching slots, bosses, and holes for assembly and position locking together;   the spring strap clip has fastening slots, bosses, and holes to be assembled to the rest of the closure system;   the spring strap connects to the spring strap clip, which then itself connects to the container base and lid;   the spring strap clip comprising a living hinge that separates the spring strap and the spring strap clip, which each connect to the lid and base;   an area of hot melt fills a cavity on the spring clip;   the extruded spring strap stores and releases energy in order to displace the lid; and   a retention latch is a part of the lid or an additional part assembled to the lid by fasteners.   
     
     
         2 . The closure system for a container of  claim 1 , wherein the area of hot melt used to fill a cavity on the spring clip prevents disassembly. 
     
     
         3 . The closure system for a container of  claim 1 , wherein the area of hot melt used to fill a cavity on the spring clip ensures proper position for the spring clip during usage. 
     
     
         4 . The closure system for a container of  claim 1 , wherein the retention latch is a user interface which acts to have the lid pop-up. 
     
     
         5 . The closure system for a container of  claim 1 , wherein the lid provides air sealing that allows the lid to effectively separate first and second environments above and below the lid. 
     
     
         6 . The closure system for a container of  claim 1 , wherein the base is connected to the lid by a physical bonding creating the living hinge. 
     
     
         7 . The closure system for a container of  claim 1 , wherein the base is connected to the lid by a snap fit creating rotation. 
     
     
         8 . The closure system for a container of  claim 1 , wherein the spring strap clip a comprises the living hinge that separates the spring strap clip into two distinctive halves. 
     
     
         9 . The closure system for a container of  claim 1 , wherein the retention latch is a user interface used to make the lid pop-up. 
     
     
         10 . The closure system for a container of  claim 1 , wherein the retention latch is more than 30 mm in width. 
     
     
         11 . The closure system for a container of  claim 1 , wherein a top surface of the retention latch is slanted at an angle comprise between 20 and 40 degrees. 
     
     
         12 . The closure system for a container of  claim 1 , wherein the retention latch further comprises walls protruding to prevent damage by accidental over traveling. 
     
     
         13 . The closure system for a container of  claim 1 , wherein
 the retention latch deforms, and a lip of the retention latch is displaced from its locked position and releases the engaged lip of the lid.   
     
     
         14 . The closure system for a container of  claim 1 , wherein the spring strap clip is connected to the lid and base by snap-in features, glue, fasteners, or a combination of snap-in features, glue, and/or fasteners. 
     
     
         15 . The closure system for a container of  claim 1 , wherein pressing on a retention latch releases a force stored in the extruded spring strap pushing back the lid allowing to access the content of a container through a reach-in area. 
     
     
         16 . The closure system for a container of  claim 1 , wherein
 the base, lid, and retention latch are made from a plastic; and   the extruded spring strap is made from extruded silicone.
