A medical liquid applicator system that includes an applicator grip assembly, a flexible reservoir and an applicator head. The applicator grip assembly is composed of a first section with a first distal end and a second section with a second distal end, a longitudinal axis, a front side, a back side, a predetermined grip length, a predetermined grip width, a fold axis separating the first section and the second section, the fold axis being perpendicular to the longitudinal axis, and a fold-activated dispensing slit located on the fold axis. The flexible reservoir is joined to a back side of the applicator grip assembly and is in liquid communication with the fold-activated dispensing slit. The applicator head is joined to the front side of the applicator grip assembly at the fold axis and is in liquid communication with the dispensing slit. The applicator grip assembly is folded at the fold axis to bring the back side of at least a portion of the first distal end of the first section and the back side of at least a portion of the second distal end of the second section together to define a grip handle having the predetermined grip length and the predetermined grip width. Folding the applicator grip assembly ruptures the fold-activated dispensing slit thereby defining a dispensing opening and also applies pressure to the flexible reservoir element in liquid communication with the dispensing slit to urge flowable medical liquid through the dispensing opening and into the applicator head.

1. A single-use, disposable, hand-held medical liquid applicator system, the applicator system comprising: a substantially rigid, flat, planar applicator grip assembly comprising a first section having a first distal end and a second section having a second distal end, a longitudinal axis, a front side, a back side, a predetermined grip length, a predetermined grip width, a fold axis separating the first section and the second section, the fold axis being perpendicular to the longitudinal axis, and a fold-activated dispensing slit located on the fold axis;a flexible reservoir joined to a back side of the applicator grip assembly, the reservoir comprising a flexible pouch and containing at least 1 milliliter of a flowable medical liquid, and the flexible reservoir in liquid communication with the fold-activated dispensing slit;an applicator head joined to the front side of the applicator grip assembly at the fold axis and in liquid communication with the dispensing slit, the applicator head comprising a porous material adapted to receive the flowable medical liquid and to release the flowable medical liquid to a substrate;a spacer section intermediate the first section and the second section of the applicator grip assembly;a first fold axis between the first section and the spacer section and a second fold axis between the second section and the spacer section, each fold axis being perpendicular to the longitudinal axis, the spacer section having a length much shorter than the first section and the second section; anda first fold-activated dispensing slit located on a first fold axis and a second fold-activated dispensing slit located on a second fold axis;wherein the applicator grip assembly is adapted to fold at each fold axis to define a grip handle and further to rupture both fold-activated dispensing slits thereby defining multiple dispensing opening and apply pressure to the flexible reservoir element in liquid communication with the dispensing slit thereby urging flowable medical liquid through the dispensing opening and into the applicator head. 2. The applicator system of claim 1, wherein the applicator grip assembly is formed of substantially rigid material selected from plastic, cardboard, reinforced paper, metal and combinations thereof. 3. The applicator system of claim 1, wherein the predetermined grip length is from about 7 cm to about 20 cm and the predetermined grip width is from about 2 cm to about 10 cm. 4. The applicator system of claim 1, wherein at least a portion of the flexible reservoir overlaps the fold axis. 5. The applicator system of claim 1, wherein the flexible reservoir contains from at least about 1 milliliter to about 30 milliliters of the flowable medical liquid. 6. The applicator system of claim 1, wherein the fold axis is equidistant from the first distal end and second distal end of the applicator grip assembly and at least one section of the applicator grip assembly contains a grip enhancer or a fold assist feature. 7. The applicator system of claim 1, wherein at least one section of the applicator grip assembly has a concave cross-section along the longitudinal axis. 8. The applicator system of claim 1, wherein at least one section of the applicator grip assembly has at least one pressure resistance stopper along the longitudinal axis to resist the complete contact between the back side of the first distal end of the first section and the back side of the second distal end of the second section. 9. The applicator system of claim 1, wherein the system further includes a liquid distribution layer positioned between the flexible reservoir and the applicator head. 10. The applicator system of claim 1, wherein the system further includes a fastening system to engage the first distal end and the second distal end as they are brought together to define a grip handle. 11. The applicator system of claim 1, wherein the applicator head is a porous, liquid permeable cellular material. 12. The applicator system of claim 11, wherein the applicator head has a generally non-planar cross-sectional profile at the fold axis prior when the applicator grip assembly is in an unfolded state and a generally planar cross-section profile at the fold axis when the applicator grip assembly is folded. 13. The applicator system of claim 11, wherein the geometry of the applicator head allows the porous, liquid permeable cellular material of the applicator head to change position while avoiding substantial changes in the density of the porous, liquid permeable cellular material upon folding of the planar grip assembly at the fold axis.
