Problems solved by technology

[0010] A common disadvantage of prior art squeeze and twist closures is that the outer part pushes against the inner closure part
This pushing makes it difficult to align the outer and inner closure parts when the user needs to open the container

Embodiment Construction

[0025] Figure 1-10 A child resistant cover lock assembly 20 is shown. The cover locking assembly 20 includes an inner cover 22 and an outer locking cover 24 . The cap lock assembly 20 is adapted to be screwed into a container 26 that includes a threaded neck 28 and a volatile liquid 30 disposed within a reservoir 32 . In this embodiment, the container 26 further includes a core 34 and a core adapter 36 mated to the threaded neck 28 (see Figure 4 )Inside. Core 34 extends through reservoir 32 , up through core joint 36 , and finally into inner cap 22 . In order for the wick 34 to wick the volatile liquid 30 out of the container 26, it is preferred that the wick 34 is formed from a conventional wicking material. Suitable wicking materials include porous / sintered plastics such as UHDPE and polypropylene; bonded fibers such as polyester and polypropylene; glass sintered fibers; porous ceramics; carbon fibers; sintered carbon; compressed wood composites ; Bundled or woven nat...

Abstract

A cap-locking assembly (20) includes an inner cap (22) having a ribbed outer surface and a locking cap (24). The locking cap includes opposing first and second engagement mechanisms(102, 104), opposing first and second stabilizing ridges (106, 108), and a plurality of ramped tabs (96), all of which are disposed on the interior surface of the locking cap. When the ramped tabs engage a lower edge of the inner cap they retain the inner cap inside the locking cap. Further, the opposing first and second stabilizing ridges coaxially align the inner cap and the locking cap. Finally, the opposing first and second engagement mechanisms engage with the ribbed outer surface (48) of the inner cap upon application of an inward force to the locking cap.

Description

[0001] Cross-references to related applications [0002] Not applicable [0003] About federally funded research or development [0004] Not applicable [0005] sequence listing [0006] Not applicable technical field [0007] The present disclosure relates to container closures, and more particularly, to child resistant squeeze and twist closures. technical background [0008] Child-resistant closures are known to prevent children from opening containers, but which can still be easily opened by adults. Two known types of child resistant closures are "push and twist" and "squeeze and twist" closures. In pushing and twisting the closure, the user must push down on the closure before twisting it to remove the closure from the container. In squeeze and twist closures, the user must first squeeze a portion of the closure before twisting the closure to remove the closure from the container. [0009] Many existing squeeze and twist closures include an inner closure member a...
