Abstract
Abstract A throw-away single-use combined plastic container and applicator contains a viscous liquid such as an underarm deodorant. The container is a one-piece member having a flexible plastic tubular body portion which is sealed at one end and a plastic applicator head portion.
The head portion has a three-dimensionally curved exterior wall, such as a hemisphere, which spreads the liquid, a bore through the exterior wall, an integral seal to seal the bore, and a knob which is twisted by the fingers. The knob is connected to the seal so that when it is twisted it breaks off the seal and unseals the bore.
The head portion has a three-dimensionally curved exterior wall, such as a hemisphere, which spreads the liquid, a bore through the exterior wall, an integral seal to seal the bore, and a knob which is twisted by the fingers.

When the ; ;; knob 21 is twisted by the fingers, ~he seal 22 is rotated and broken ~ff, exposing the bore 17 through which the liquid 25 flows. Since the liquid 25 is thick and viscous, it will flow only when the tube 11 is squee~ed by the fingers of the user.
.,, The seal 2Z consists of an upper solid p~rtion 23 and a lower . . annular portion 24. The annular portion of the seal, being the weaker portion, is broken when the seal is twisf~ed by the knob 21.
The viscosity of the liquid deoclorant is in the range of 1500-7000 centipoise, tested b~ the Brookfield RTV instrument at 100 RPM.
; ~ A suitable gellant may be added as a thixotrope to adjusS the visco~ity to f the preferred range.
The ridges ancl valleys 37 may be of various forms or may be omitted to ~rovide a smooth surface. In the embodiment of Figure 4 the ~j 15 curved wall has parallel grooves 28. In the embodiment of Fi~ure 5 the .
., curved wall has small rounded depressions 29. In Figure 6, showing the ~-~ curved wall after the seal is broken, the wall has curved protruding bumps ~, 30. I n Figure 7 the curved wall has a crinkled surface 31 .
In use, the user squee2es inwardly on the siclewall 11 of the container 10. The tube's sidewalls will press inwardly on the liquid 25 .~ in the eontainer 10. The liquid will be squeezed out through the bore 17 and will flow on the outer surface 26 of the curved portion 15. The .
liquid will be caught by the ridges and valleys 27 of the hemispherical ~' portion 15. The user will then use the curved portion 15 to spread the ! 25 liquid over the skin. The user continues to squirt liquid from the container by squeezing inwardly on its tubular sidewalls 11 until the use is completed ~`, or until the container is empt~. The container will then be disposed of, for example, by throwing it in the trash.
In the roll-on type of deodorant con~ainer, usin~ a rollable ball~
-`; 30 the rotation of the ball spreads a thin layer of the liquid deodorant on ~,, the surface of the ball. The liquid does not generally drip onto the user's fingers, by the force of gravitV, because the layer is t~lin, the liquid is thick [viscousl and the ball does not repel the liquld.

13282~ 1 In the container and applier of the present invention, it is I important that the liquid which issues from the opened bore is able to be ; spread over the curved wall without dripping on the user's fingers. To obta;n this result, as explained above, a thick ( viscous I liquid is used . Theplastic resin of the container, pre~erably polyethylene, permits wetting of its surface by the liquid, i.e., the contact angle lies between 0 and 90.
If necessary, a small amount of a detergent may be added to the liquid to increase its wetting on the curved wail and reduce its surface tension ., (force acting on the liquid tending to minimize its surface).
Alternatively, the surface of the curved wall, i.e., the hemisphere, may be treated with a suitable wetting agent to increase its wettability to the !iquid,i.e., reduce the liquid-solid contact angle. The remainder , of the container would not be treated with the wetting agent.
The surface of the curved wall in the embodiment described above is a hemisphere. Al$ernatively, other wall shapes may be used for the dome curved portion 15; for example, the dome may be oval (egg-shaped ';! or conical.
