Single use toothbrush and whitening touch up device and dermatological applicator
View Patent ↗An applicator having a squeezable vessel, an applicator tip, a crenellated ring and a sponge. The vessel contains contents that react upon contact with a reactive ingredient treated onto the sponge. By squeezing the vessel, the contents are urged to leave the vessel to pass through a hollow of the applicator tip to reach the sponge. The sponge has a peripheral edge that faces inward facing surfaces of elastomeric formations of the crenellated ring. The elastomeric formations are each separated from each other in succession. The elastomeric formations at the distal end of the crenellated ring may have a greater depth than that of the sponge, which in turn may have a greater depth than elastomeric formation(s) at a proximal end of the crenellated ring.
1. An applicator, comprising a vessel, an elongated applicator tip, a sponge and a crenellated ring surrounding the sponge, each extending outwardly from a side of an end of said applicator tip, the crenellated ring having a plurality of elastomeric formations, each spaced from each other in succession by respective gaps, each elastomeric formation having a distal surface with at least one recessed area, the vessel containing contents and a mechanism that enables the contents to be urged out of the vessel through an opening in the vessel under manual pressure, the applicator tip being in fluid communication with the opening to receive the contents urged out from the vessel, the applicator tip being hollow to allow the contents to pass through the applicator tip to dispense through a distal opening of the applicator tip to reach the sponge, the distal opening being spaced away from the vessel, the sponge being treated with a reactive ingredient that reacts upon contact with the dispensed contents that reach the sponge.
2. The applicator of claim 1 , wherein the elastomeric formations each have an outward surface configuration including said at least one recessed area, the outward surface configuration being selected from a group consisting of a recessed V-shape, a projecting V-shape, and a sinusoidal, wavy shape.
3. The applicator of claim 1 , wherein the sponge has a peripheral edge facing outward toward inward facing surfaces of the elastomeric formations of the crenellated ring.
4. The applicator of claim 3 , wherein the inward facing surfaces of the elastomeric formations abut the outward facing peripheral edge of the sponge.
5. The applicator of claim 1 , wherein the crenellated ring has a distal end portion and a proximal end portion, the distal end portion being further away from the vessel than the proximal end portion, the elastomeric formations at the distal end portion having a height that is greater in dimension than that of proximally located elastomeric formations.
6. The applicator of claim 5 , wherein the height of the elastomeric formations at the distal end portion is greater in dimension than a height of the sponge.
7. The applicator of claim 5 , wherein a height of the elastomeric formations at the proximal end portion is smaller in dimension than the height of the sponge.
8. The applicator of claim 1 , wherein the contents of the vessel include a gel and the reactive ingredient of the sponge is bicarbonate soda.
