DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0021] Referring to FIGS. 2 and 5, the preferred embodiment of an
eyelash-adhesive dispensing pen according to this invention
includes a pen unit 20, an ejecting unit 30, a rear connecting
device 40, and a unidirectional rotation unit 50.
[0022] The pen unit 20 includes a pen body 21, a fixed member 22, a
front connecting device 23, a rear cap 24, a pen core member 25, a
pen tip member 26, and a front cap 27.
[0023] The pen body 21 has a front end 211, a rear end 212, and an
inner wall surface 213 surrounding an axis (I) and defining an
inner hole 214.
[0024] With further reference to FIGS. 3 and 6, the fixed member 22
is disposed fixedly in the pen body 21, and has an inner surface
221, an outer surface 222, and a flange 224 extending radially and
inwardly from the inner surface 221 and formed with a threaded hole
223 that extends along the axis (I). Alternatively, the fixed
member 22 may be formed integrally with the pen body 21.
[0025] With further reference to FIG. 9, the front connecting unit
23 includes a plurality of angularly equidistant ribs 231 extending
radially and inwardly from an inner wall surface of the pen body 21
to define a plurality of retaining grooves 231', and a plurality of
angularly equidistant retaining projections 232 extending radially
and outwardly from the fixed member 22 and engaging respectively
some of the retaining grooves 231', so as to prevent rotation of
the fixed member 22 in the pen body 21.
[0026] With particular reference to FIGS. 2, 5, and 6, the rear cap
24 has an inner surface 241 and an insert portion 242 inserted into
the rear end 212 of the pen body 21 and disposed behind the fixed
member 22 such that it is rotatable on the rear end 212 of the pen
body 21.
[0027] The pen core member 25 includes a connecting seat 251
disposed fixedly in the pen body 21 and defining a front end of an
adhesive receiving chamber 215, and a core tube 252 extending
forwardly from the connecting seat 251 and formed with an adhesive
outlet 253. The adhesive outlet 253 has a diameter smaller than
that of the inner hole 214 in the pen body 21.
[0028] The pen tip member 26 is disposed fixedly in the front end
211 of the pen body 21, is sleeved around the core tube 252, and
has a frustoconical front end 261 permitting the core tube 252 to
extend therethrough in a close fitting manner, so as to position
the core tube 252 in the pen body 21.
[0029] The front cap 27 is sleeved removably on the front end 211
of the pen body 21 for covering front ends of the pen core member
25 and the pen tip member 26.
[0030] The ejecting unit 30 includes a rotating shaft 31 and an
adhesive pushing block 32.
[0031] With particular reference to FIGS. 2 and 6, the rotating
shaft 31 has a threaded rod portion 311 engaging the threaded hole
224 in the fixed member 22, a frustoconical insert end 312, and two
opposite flat surfaces 313 that are parallel to each other and that
are symmetric about the axis (I).
[0032] The adhesive pushing block 32 is sleeved fixedly and
sealingly on the insert end 312 of the rotating shaft 31 and in
sealing contact with the pen body 21 to define the adhesive
receiving chamber 215 in the pen body 21 between the adhesive
pushing block 32 and the connecting seat 251 of the pen core member
25. The adhesive pushing block 32 is made of silicone or rubber
such that a liquid-tight seal is established between the adhesive
pushing block 32 and the pen body 21.
[0033] As such, the rotating shaft 31 is rotatable relative to the
fixed member 22 to move the adhesive pushing block 32 toward the
adhesive outlet 253 along the axis (I) to thereby eject the eyelash
adhesive out of the adhesive receiving chamber 215 through the
adhesive outlet 253.
[0034] With particular reference to FIGS. 2, 6, and 7, the rear
connecting unit 40 includes a plurality of angularly equidistant
insert strips 41 extending from the inner surface 241 of the rear
cap 24 and along the axis (I), and a plurality of engaging grooves
42 that are formed in the rotating shaft 31 and that engage
respectively some of the insert strips 41, so that the rotating
shaft 31 is co-rotatable with the rear cap 24. The flat surfaces
313 are positioned to prevent the remaining insert strips 41 from
contact with the rotating shaft 31.
[0035] With particular reference to FIGS. 2, 3, 5, 6, and 8, the
unidirectional unit 50 includes a rotating member 51, a plurality
of first ratchet teeth 52, a plurality of second ratchet teeth 53,
an intermediate connecting unit 54, and a resilient member 55.
[0036] The rotating member 51 is sleeved on the rotating shaft 31,
and has a rear portion disposed within the insert portion 232 of
the rear cap 24, a front portion extending into the fixed member
22, and a flange 513 extending radially and inwardly from the front
portion.
[0037] The first ratchet teeth 52 extend from the flange 513 of the
rotating member 51.
[0038] The second ratchet teeth 53 extend from the flange 224 of
the fixed member 22, and engage the first ratchet teeth 52.
[0039] The intermediate connecting device 54 includes a plurality
of first splines 541 extending inwardly from said rear cap 24, and
a plurality of second splines 542 extending outwardly from the
rotating member 51. Each of the first splines 541 extends into a
space defined by two adjacent second splines 542, so as to allow
for co-rotation of the rotating member 51 with the rear cap 24.
[0040] The distance between the axis (I) and the first splines 541
is smaller than that between the axis (I) and the ribs 231.
[0041] Due to the presence of the intermediate connecting unit 54,
the rear cap 23 is co-rotatable with the rotating member 51.
[0042] The resilient member 55 is configured as a compression
spring that is disposed in the rear cap 24 and the rotating member
51 and that is sleeved on the rotating shaft 31 between the flange
513 of the rotating member 51 and the insert strips 41. As such,
the rotating member 51 is biased by the resilient member 55 toward
the fixed member 22 to engage the first ratchet teeth 52 with the
second ratchet teeth 53.
[0043] With particular reference to FIGS. 5, 6, and 10, during use,
it is only necessary to rotate the rear cap 24 relative to the pen
body 21 so as to drive synchronous rotation of the rotating member
51 and the rotating shaft 31, thereby moving the adhesive pushing
block 32 toward the adhesive outlet 253 to eject the eyelash
adhesive out of the adhesive outlet 253. Since the rotating shaft
31 is threaded into the threaded hole 223 in the fixed member 22,
and a clicking sound is produced during relative rotation between
the first ratchet teeth 52 and the second ratchet teeth 53, the
rotational angle of the rotating shaft 31, the distance traveled by
the adhesive pushing block 32, and thus the amount of the eyelash
adhesive flowing from the pen can be controlled precisely.
Furthermore, due to the presence of the unidirectional rotation
unit 50, the adhesive pushing block 32 is limited to move toward
the adhesive outlet 253, thereby resulting in convenience during
operation.
[0044] In view of the above, the eyelash-adhesive dispensing pen of
this invention has the following advantages: [0045] 1. The amount
of the eyelash adhesive flowing of the pen can be controlled
precisely so as to avoid consumption of the eyelash adhesive.
Furthermore, the pen is easy to use. [0046] 2. Since the rotating
shaft 31 rotates in only a single direction, the eyelash adhesive
is ejected out as long as the rear cap 24 is rotated. That is, the
eyelash adhesive cannot be retracted into the pen, so that
undesired entrance of air into the pen can be prevented, thereby
further resulting in convenience during use.
[0047] With this invention thus explained, it is apparent that
numerous modifications and variations can be made without departing
from the scope and spirit of this invention. It is therefore
intended that this invention be limited only as indicated by the
appended claims.
