Applicator tip for liquid applicator device

In a liquid applicator device comprising an applicator liquid container and a liquid dispensing mechanism having a valve element being movable between an open position and a closed position for controlling the flow of applicator liquid from the container, the applicator liquid dispensing mechanism having a hollow cylindrical respite for supporting an applicator tip with an inner end of the applicator tip communicating with the valve element for permitting the flow of applicator liquid from the container to the inner end of the applicator tip upon an axial displacement of the applicator tip to move the valve element into the open position for enabling the applicator liquid to migrate to an outer end of the applicator tip for applying the liquid to a surface, the improvement comprising:

• a recess defined in said applicator tip;
• a generally toroidal retaining ring;
• said generally toroidal retaining ring disposed in said recess of said applicator tip;
• and
• said retaining ring cooperating with said recess for preventing removal of the applicator tip from the a liquid applicator device.

• said applicator tip having an annular recess disposed between said outer end and said inner end;
• a generally toroidal retaining ring;
• said retaining ring being slideably disposed within said annular recess with said retaining ring forming an interference fit with said annular recess of the applicator tip for limiting movement of said retaining ring only within said annular recess;
• and
• said retaining ring forming an interference fit with the hollow cylindrical respite for preventing removal of the applicator tip from the liquid applicator device.

In a liquid applicator device comprising an applicator liquid container and a liquid dispensing mechanism, the liquid dispensing mechanism comprising an inner and an outer assembly, the inner assembly having a valve body receivable in an open end of the container with a valve element positioned within said valve body biased into engagement with a valve seal;

• the outer assembly including a hollow cylindrical respite for supporting an applicator tip with an inner end of the applicator tip communicating with the valve element for permitting the flow of applicator liquid from the container to the inner end of the applicator tip upon an axial displacement of the applicator tip to move the valve element out of engagement with the valve seal for enabling the applicator liquid to migrate to an outer end of the applicator tip for applying the liquid to a surface, the improvement comprising:
• the applicator tip having an annular recess disposed between said outer end and said inner end;
• a generally toroidal retaining ring disposed in said annular recess of said applicator tip;
• a hollow cylindrical closure having a shoulder disposed thereon for receiving said retaining ring disposed on said applicator tip;
• the outer assembly being securable to the inner assembly for entrapping the retaining ring disposed in said annular recess between the outer and the inner assemblies for preventing the removal of the applicator tip from the liquid applicator device.

In a liquid applicator device comprising an applicator liquid container and a liquid dispensing mechanism having a valve being movable between an open position and a closed position for controlling the flow of applicator liquid from the container, the liquid dispensing mechanism having a support portion for supporting an applicator tip communicating with the valve for permitting the flow of applicator liquid from the container to the applicator tip upon movement of the valve into the open position for applying the applicator liquid,

• the improvement comprising:
• said applicator tip having a recess extending between an inner shoulder and an outer
• shoulder;
• a retaining ring;
• said retaining ring defining an inner diameter and an outer diameter;
• said retaining ring being disposed for movement within said recess of said applicator tip;
• said retaining ring being disposed for movement within a respite defined in the liquid dispensing mechanism;
• said inner diameter forming an interference fit with said inner and outer shoulders of said recess for limiting the independent movement of said retaining ring within said annular recess;
• said outer diameter of said retaining ring forming an interference fit with said respite defined in the liquid dispensing mechanism for limiting the movement of said retaining ring within said respite;
• and
• said interference fit of said inner diameter cooperating with said interference fit of said outer diameter for preventing removal of the applicator tip from the liquid applicator device.
