An improved swab applicator is provided including a swab (3) connected to an elongate stick (5). The swab applicator further includes a sleeve (1) encapsulating the swab and stick including a handle portion (9), receptacle portion (17)and transition portion (13). The handle portion is preferably hollow and cylindrical in shape extending a substantial part around the length of the stick, while the receptacle portion of the sleeve is also hollow and cylindrically shaped having a substantially greater cross section than the handle portion. Meanwhile, the transition portion is preferably hollow and fristoconically shaped to connect the handle portion to the receptacle portion of the sleeve. The transition portion is substantially non-deformable when the receptacle portion of the sleeve is compressed creating a significant level of sheer stress to be imparted between the receptacle portion and transition portion of the sleeve causing the receptacle portion to sever from the rest of the sleeve.

La présente invention concerne un écouvillon applicateur amélioré comprenant un écouvillon (3) relié à un bâton allongé (5). L'écouvillon applicateur comprend également un manchon (1) dans lequel sont encapsulés l'écouvillon et le bâton, ledit manchon comportant une partie manche (9), une partie réceptacle (17) et une partie de transition (13). De préférence, la partie manche est creuse et de forme cylindrique et s'étend en grande partie autour de la longueur du bâton, tandis que la partie réceptacle du manchon est creuse également et de forme cylindrique mais possède une section transversale sensiblement plus grande que la partie manchon. La partie de transition est de préférence creuse et de forme tronconique afin de relier la partie manche à la partie réceptacle du manchon. La partie de transition est sensiblement non déformable lorsque la partie réceptacle du manchon est comprimée, ce qui crée un niveau significatif de contrainte de cisaillement entre la partie réceptacle et la partie de transition du manchon entraînant la rupture de la partie réceptacle qui se sépare alors du reste du manchon.
