ABSTRACT:
An applicator for delivering liquids or gels to solid surfaces. It comprises a liquid or gel filled hollow flexible bulb having a top and bottom. There is an opening in the bottom of the bulb containing a rupturable seal. A spike is fitted within the hollow bulb. This spike is positioned vertically above the rupturable seal and is capable of rupturing the seal in response to the application of downward pressure on the top of the bulb.
There is also present a sponge attachment plate having a top and a bottom which are connected by a channel. The top of the channel engages the opening in the bottom of the bulb. The bottom of the channel is in fluid communication with a sponge secured to the bottom of the sponge attachment plate. The applicator is particularly useful for delivering gelled antimicrobial products to localized areas of the body.
