KNOCKING TYPE SOLID COSMETIC CONTAINER
BACKGROVND OF THE INVENTION
Field of the Invention
The present invention relates to a knocking type
cosmetic container capable of delivering an lipstick, eyeliner,
eneshadow or the like stick type solid cosmetics.
Prior Art
Hithexeto, in containers which deliverably contain
stick type of solid comsetics, there have been employed screw
delivery mechan-sms as a delivery means.
In such conventional containers that have delivery
means relying on the screw delivery mechanisms, since it is
necessary to rotate some portion of the container when deliver
the solid cosmetic for use, there has been involved such
inconvenience that it is difficult to handle the container one-
handed and thus both hands enevitably must be used.
Further, if the solid cosmetics are stored unused for
a long time, there is also involved such problem that, they so
stick to the container as to make the delivery thereof
difficult in an ordinary delivery operation at the start of
use.
The present invention is aimed to at provide a
knocXing type solid cosmetics container capable of delivering
operation for operation for allowing the operability to the
more simple and convenient cosmetics merely through one hand
knocking. Further, the present invention is aimed at providing
a knocking type solid cosmetics container capable of smoothly
delivering even such solid cosmetics that are stored unused for
2(~7~7
a long time.
SUMMARY OF THE INVENTION
According to the present invention, there can be
provided a knocking type solid cosmetics container which
comprises a tubularr container main body consisting of a first
shaft and a second shaft; a cylindrical pushrod housing pipe
inserted in the container main body, a rear end thereof being
projected out with a given length from the container main body;
a delivery chuck fixedly provided on a front end of the pushrod
housing pipe, a frontward outer periphery portion thereof being
flared or trumpet-shaped and said delivery chuck being formed
with wedge-shaped slits widening frontward; a pushrod inserted
passing through into the pushrod housing pipe and the delivery
chuck; a tubular cartridg having a pushrod holding member
therein: and a piston contained axially movably in the
cartridge and having a pushrod receiving portion.
The pushrod may be previously provided in the
container main body or in the cartridge by arranging the length
of the pushrod such that, when the container main body and the
cartridge are connected, the pushrod may push the piston by a
given distance as a result of such connection, the solid
cosmetic can be easily delivered even if it has been sticked to
the container.
The same effect can be achieved by an arrangement
wherein a cap is mounted on a rear end of the pushrod housing
pipe, a given idle space is left between a step portion of the
cap and the rear end of the first tubular shaft, and a given
idle space is left between the base portion of the piston and

DETAILED DESCRIPTION AND THE PREFERRED EMBODIMENTS
The present invention will now be described by way of
unlimitative embodiments applied to lipstick containers.
Referring to Figs. 1-4, there is illustrated a first
-- 3
20~72~7
embodiment. In these figures, the reference numeral 1 denote a
container main body, 2 a cartrid~e and 3 a pushrod~ In this
embodiment, the pushrod 3 is previously mounted in the
cont~iner main body 1.
The container main body 1 consists of a first tubular
shaft 4 and a second tubular shaft 5 screwed on the front
portion of the former.
In the container main body 1 is inserted a
cylindrical pushrod housing pipe 6 having a shorter length than
the container main body 1. The rear end of the pushrod housing
pipe 6 projects out with a given length from the rear end of
the container main body 1, and on the projecting end is put a
cap 7 serving as a knocking member. Between the step portion
of the cap 7 and the rear end of the container main body 1 is
left a given space which accounts for one stroke of knocking
motion of the pushrodhousing pipe 6. On the outer wall of a
central portion of the pushrod housing pipe 6 is provided a
flanged spring seat 8.
On the front end of the pushrod housing pipe 6 is
fixedly mounted a delivery chuck 9, which is cylindrical with
its frontward outer side flared or trumpet-shaped. On the
front end of the delivery chuck 9 are formed three wedge-shaped
slits 10 widening toward the end.
Between the front end of the first shaft 4 and the
delivery chuck 9 is provided a ring-shaped delivery chuck
fastener 11, which has such inner diameter as smaller than
maximum outer diameter but larger than minimum outer diameter
of the delivery chuck ~. The delivery chuck fastener 11 is
2057247
axially slidable a~ a predetermined distance together with the
delivery chuck 9.
On the inner wall of the front shaft 4 is provided a
step 12 which serves as a spring seat at a place frontward to
the spring seat 8 of the pushrod housing pipe 6, while between
the spring seat 8 and the step 12 is provided a coil spring 13
surrounding the pushrod housing pipe 6. The coil spring 13
always urges rearward both the pushrod housing pipe 6 and the
delivery chuck 9 fixed thereto with respect to the container
main body 1.
In the through holes of the pushrod housing pipe 6
and the delivery chuck 9 is inserted the pushrod 3 whose rear
end i5 first located at a rearmost position, namely a position
at which the rear end of the pushrod 3 abuts against the cap 7.
A stopper 24 which collides with a pushrod holding
member 20 may conveniently be provided projectingly from the
rear end of the pushrod 3, lest the pushrod 3 should lastly
slip out of the container when it is pushrod to the last
extremity.
The cartridge 2 is cylindrical and has a large
diameter portion 14 for containing a solid cosmetic 22 and a
small diameter portion 15 for connecting to a front portion of
the container main body 1. A piston 16 is provided in the
large diameter portion 14. The piston 16 is concentrically
provided on one side of its base 17 with a front rib 18 having
the same outer diameter as the inner diameter of the large
diameter portion 14 and on the opposité side thereof with a
rear rib 19 having the same outer diameter as the inner
20~7247
diameter of the small diameter portion 15. On a state with the
rear rib 19 and the ~ront rib 18 of the piston 16 respectively
inserted in the small diameter portion 15 and the large
diameter portion 14, the solid cosmetic is charged in the
cartridge 2 and the piston 16 is pushed by the pushrod 3 to
advance the solid cosmetic.
At a position rearward the rear rib 19 of the small
diameter portion 15 is provided a tubular pushrod holding
member 20 made of rubber. The pushrod holding member 20 may be
formed integrally with the cartridge 2 as shown in Fig. 5.
On the outer wall of the small diameter portion 15 is
formed a screw thread 21 which cooperates with a corresponding
screw thread formed on the frontward outer wall of the
container main body 1 to engage with each other.
Now, the operation of the container willl be
described. In the sate shown in Fig. 1, with the coil spring
13 urging the pushrod housing pipe 6 rearward, the delivery
chuck 9 is closed tight with its outer wall abutting against
the delivery chuck fastener 11 and it fastens the pushrod 3,
thereby bringing the entire container to a state of standstill.
Pushing or knocking the cap 7 advances the pushrod housing pipe
6 by one stroke. On first knocking, the cap 7 simultaneously
pushes the pushrod 3 which advances by one stroke to push the
piston 16 of the cartridge 2 and the advance of the piston 16
causes the solid cosmetic to be delivered through front end
opening in an amount corresponding to said one-stroke.
When the cap 7 is released from knocking, both the
pushrod housing pipe 6 and the delivery chuck 9 are forcibly
2~7247
urged rearward by the action of the coil spring 13, and the
delivery chuck 9 is closed tight by the delivery chuck fastener
11 to fasten the pushrod 3. Then, the pushrod 3 is restrained
from moving back by the pushrod holding member 2~ and thus is
left as it stands at the advanced position. Upon the next
knocking operation, the pushrod 3 is moved forward by the
delivery chuck 9 which is effectively holding the p~lshrod 3 and
thus the solid cosmetic is delivered as described above. By
only repeating these knocking operations, the solid cosmetic is
successively delivered for use.
In case of necessity, when the solid cosmetic thus
delivered is required to be drawn in, it can be pushed back
while leaving the cap 7 in fully knocked condition. Then, as
shown in Fig. 8, the delivery chuck 9 is released from the
fastening by the delivery chuck fastener ll and the front end
of the delivery chuck 9 opens to free the pushrod 3 to allow
the solid cosmetic to be easily pushsed back.
Figs. 7-9 illustrate another embodiment of the
lipstick container. Though the pushrod 3 is previously housed
in the container main body 1 in the above embodiment, it is
housed in this embodiment in the cartridge 2. Further, the
length of the pushrod 3 is arranged a little longer than that
in the above embodiment. Except for the above, structures and
operation thereof are the same as those in the above
embodiment.
In this embodiment, as shown in Figs. 7, 8 and 9, the
pushrod 3 is such arranged that, the length a from the rear end
of the pushrod 3 to the rear end step 19 of the large diameter
20~7247
portion 14 is a little longer, for example by several mm, than
the length b from the abutting face 23 of the cap 7 against the
pushrod 3 to the front end of the container main body 1.
Accordingly, when connecting the container main body 1 with the
cartridge 2, the pushrod 3 obstructs the complete connection of
the container main body 1 and the cartridge 2 and if they are
forcedly connected, then the piston 16 is pushed forward by the
length difference (a-b) to force out the solid cosmetic. Since
the foxce for forcedly connecting them is far stronger than
that caused by the knocking operation of the cap 7, even if the
solid cosmetic is sticked to the container, it can be delivered
with its sticked state easily broken off, thereby allowing the
subsequent operation to be smoothly performed.
This arrangement can also be applied substantially in
the same way to the container of the above first embodiment
wherein the pushrod 3 is previously provided in the container
main body 1. Namely, by designing the dimension such that the
length c shown in Fig. 3 is somewhat longer than that d shown
in Fig. 4, the same function and effect can be obtained.
Fig. 10 shows a further embodiment of the present
invention. In this embodiment, as shown in Fig. 10, when the
cartridge 2 is first connected to the container main body 1,
the pushrod 3 under unknocked state and the piston 16 are not
yet completely connected to leave a given gap ~ between the
front end of the pushrod 3 and the base portion of the piston
16. And, there is so designed that the gap ~ i5 smaller than
the space ~ between the step portion of the cap 7 and the rear
end edge of the first shaft 4.
2~72~7
When the cap 7 is fully knocked to advance from the
state of Fig. 10 until the front end thereof abuts against the
rear end edge of the container main body 1, the front end of
the pushrod 3 first abuts against the base portion of the
piston 16 at t~e state ~he pushrod 3 has advanced by ~ and
further knocking of the cap 7 causes the piston 16 to further
advance by the distance corresponding to the difference (~
thereby advancing the solid cosmetic together with the piston
16.
The container according to the present invention may
be made of any conventional material. For example, all the
parts except for the coil spring 13 may be made of synthetic
resins, while the delivery chuck 9 and the delivery chuck
fastener 11 may be made of metalic materials.
