Description
A CHILD RESISTANT ENCLOSURE
This International Application claims priority from a complete patent application filed in India having Patent Application No. 201911038456, filed on September 24, 2019 and titled “A CHILD RESISTANT ENCLOSURE”
FIELD OF INVENTION
Embodiments of a present invention relate to a child resistant enclosure, and more particularly to a child resistant enclosure comprising a double wall squeeze.
BACKGROUND
Child-resistant packaging/ enclosure or CR packaging/ enclosure is special packaging used to reduce the risk of children ingesting hazardous materials. This is often accomplished by the use of a special safety cap. Different types of CR packaging are available. One such type includes one-piece push and turn CR enclosure. Such CR enclosure requires minimal pressure and turn on the CR enclosure to open or remove the enclosure from a bottle. However, such CR enclosures are very easy detachable from the bottle. Due to such limitations, the one-piece push and turn CR enclosure are less reliable as safety of children becomes a compromise.
Another type of CR enclosure includes Two-piece push-and-turn child-resistant (CR) closures which are observed to be safer than the one-piece push and turn CR enclosure. Such CR enclosures have two sections mostly on opposite directions to each other which has to be pushed together and turned in order to detach the enclosure from a bottle. However, such CR enclosure are notorious for being hard to open and reclose because of the poor design of locking lugs, causing user frustration, as well as potential cocked caps during application on the packaging line. Also, such CR enclosures are relatively expensive and less user friendly due to hardness in operating the CR enclosure. In addition, due to the poor design, the CR enclosure leads to misalignment and/or cocked caps, thereby making such CR enclosures less reliable.
Hence, there is a need for an improved child resistant enclosure to address the aforementioned issues.
