fig1 illustrates the main components of a test applicator for mascara . a substantially elongated cylindrical container 1 is provided . the main body 2 of this container 1 holds the mascara ( not shown ). a neck 3 is placed on the opening of the main body 2 , forming a single piece therewith ; a closure cap , which is designated by 4 in its entirety , is detachably insertable into the neck 3 . the closure cap 4 consists of a handle member 5 , which remains outside the neck ; a closing member 6 , which can be inserted and anchored in the container neck 3 , closing the container 1 ; and a shank 7 to be positioned in the container , serving for the mounting of the virtual applicator in the form of a mascara brush 8 . when the container 1 is filled and closed , the mascara brush 8 dips into mascara . in order for excess liquid to be removed that adheres to the brush 8 when it is withdrawn from the container 1 , provision is made for a stripping device 9 — a so - called “ wiper ”— which is located between the shank 7 of the closure cap 4 and the neck 3 of the container 1 . this wiper 9 is a substantially annular insert , which tapers in the direction of insertion e of the closure cap 4 and is equipped with a centrical orifice 10 for the mascara brush 8 and the shank 7 . the inside diameter of the orifice 10 is smaller than the outside diameter of the mascara brush 8 so that the mentioned mascara stripping effect is attained upon withdrawal of the brush 8 . for the closure cap 4 to be fixed in the container neck 3 , an encircling annular locking projection 12 is provided on the outer jacket 11 of the closing member 6 ( fig2 ), cooperating with an encircling annular locking - recess 13 in the form of a complementary groove on the inside 14 of the container neck . upon insertion of the closure cap 4 into the container neck 3 , the locking projection 12 and the locking recess 13 engage with each other , which ensures the container 1 to be safely mounted and tightly closed . as seen in particular in fig3 the edge 16 which encircles the insertion hole 15 of the neck is designed as a peripherally encircling , more or less serrated wave pattern 17 , which cooperates with a complementarily serrated counterpart wave pattern 18 on the end , on the side of the container , of the handle member . s of the closure cap 4 . the counterpart pattern 18 is roughly outlined by the noses 19 seen in a section in fig2 . the wave pattern 17 and the counterpart pattern 18 may be simplified to such an extent that only a slope and a counterpart slope will remain . in the position of interlocking of the locking projection 12 and the locking recess 13 , the wave pattern 17 and the counterpart wave pattern 18 rest within each other so that , upon rotation of the closure cap 14 about its axis of rotation 20 , the counterpart pattern 18 is lifted from the wave pattern 17 , which releases the interlocking . opening the closure cap 4 takes place conveniently by rotation as the consumer is used to . another special feature of the mascara tester resides in the attachment and mounting of the wiper 9 . in the intermediate stage of manufacture seen in fig2 the wiper 9 is placed by gentle press - fit , and thus fixed , on an annular shoulder 21 of the closing member 6 . the shank 7 for the mascara brush 8 reaches through the orifice 10 . an annularly encircling locking projection 22 is provided outside on the wiper 9 approximately centrally of the longitudinal extension thereof and cooperates with a corresponding encircling locking recess 23 on the inside 14 of the container neck 3 . in the direction of insertion e , this locking recess 23 is located further inwards than the mentioned locking recess 13 that cooperates with the locking projection 12 of the closure cap 4 . on the edge of the wiper 9 that is turned away from the orifice 10 — i . e . after the locking projection 22 in the direction of insertion e — an encircling annular stop projection 24 that sticks out is molded on in a single piece , cooperating with an annular stop shoulder 25 on the container neck 3 . counter to the direction of insertion e , the annular stop shoulder 25 is preceded by a flat , annularly encircling rear recess 26 , which ensures additional locking engagement of the wiper 9 via the annular stop projection 24 . as seen from the illustration of the handle member 5 of fig1 and 2 , the handle member 5 has a concave shape externally , which gives a recessed grip 29 and is especially handy . the handle member 5 is hollow virtually over its entire length and open counter to the direction of insertion e . this opening 27 of the handle member 5 is encircled by a plane ring surface 28 so that the handle member 5 can be seized and manipulated in a defined way by means of a handling tool of an automatic assembly machine . afterwards , the opening may be closed by a cap 30 ( roughly outlined by dashes in fig1 ). the process of mounting , filling and closing takes place mechanically by the closure cap 4 and the wiper 9 being pre - assembled as the unit seen in fig2 and then supplied to the course of manufacture . the container 1 is filled in the completely opened condition via the neck 3 which , as seen in fig3 has no constriction . then the automatic handling machine presses the unit formed by the closure cap 4 and the wiper 9 — mascara brush 8 first — in the direction of insertion e into the container 1 . the locking projection 22 of the wiper 9 engages with the corresponding locking recess 23 on the container neck 3 , fixing the wiper 9 . the locking projection 12 on the closing member 6 engages with the corresponding locking recess 13 on the container neck 3 , as a result of which the closure cap 4 is reliably retained on the container 1 . when the mascara tester is opened for the first time , the press - fit of the wiper 9 on the closing member 6 is released as the closure cap 4 is withdrawn and the wiper 9 retained in the container 1 by the interlocking 22 / 23 . for the sake of completeness , it must be added that the container 1 , the closure cap 4 and the wiper 9 may consist of customary plastic materials such as pp , pe , pet , pvc or pa . as for the design of the handle member 5 , various cross - sectional shapes are conceivable ; but , given the concavely recessed grip 29 , a round cross - sectional shape must be preferred for ergonomic reasons .
an applicator assembly for cosmetic liquids , in particular a mascara tester , is provided with a container for holding the cosmetic liquid , a closure cap for the container and a wiper for the cosmetic liquid , which lodges in the neck of the container . in an intermediate stage of manufacture of the applicator assembly , the wiper is detachably mounted on the closure cap . in a subsequent stage of manufacture , upon insertion of the closure cap into the container neck , the wiper is durably fixed there .
