, COSMETIC CASING CAPABLE OF PROTRUDING COSMETIC MATERIAL
BACKGROUND OF THE INVENTION
This invention relates to a casing capable of protruding a cosmetic material such as lipstick contained in the casing.
Conventionally, an ordinary casing capable of putting : .. .....
out a cosmetic material such as lipstick contained therein has a structure wherein a stick of rouge is protruded from the body of the casing by a certain kind of prot~ruding operation, e.g., rotation of a member on the casing body.
It is convenient to design such an article so that the cap is automatically opened and closed in a linked relatioship with the protrudlng operation in order to eliminate the need for a separate operation of removing the cap. ~ ~;
In consideration of this point, the applicant of the present invention has proposed a stick-type cosmetic materlal casing which is disclosed in Japanese Utility Model Laid-Open No. 58-88914 and has a structure such as that shown in Figs. 11 and 12.
This casing is construc~ed as described below. A lid 242 is attached to the upper end of a screw tube 219. The screw tube 214 has an inner helical groove 215 formed in its inner peripheral surface and an engaging pro]ection 238 formed on the inner peripheral surface of its lower portion.
.
~ A tubular body 201 is fitted in the screw tube 214. The ` 133~96~ ;
tubular body 201 has an elongated aperture 202 extending in the axial direction and an outer helical groove 221 formed in the outer peripheral surface of its lower portion. The engaging projection 238 of the screw tube 214 is fitted in the outer helical groove 221.~ A closed inner tube 209 is fitted in the tubular body 201 while an engaging projection 210 formed on the inner tube 209 is fitted in the inner helical groove 215 of the screw tube 214 through the elongated`aperture 202 of the tubular body 201. A tail tube 220 is fitted on and fixed to the outer peripheral surface of the rear end portion of the tubular body 201.
As the tubular body 201 is rotated by an operation of turning the tail tube 220 while supporting the screw tube 214, the screw tube 214 is moved downward by the cooperation of the outer helical groove 221 and the engaging projection , : ::
238 and the inner surface of the lid 292 is brought into contact with the upper end of the tubular body 201 whereby the lid 242 is turned and opened, as shown in Fig. 12. At the same time, the inner tube 209 is moved upward by the cooperation of the inner helical groove 215 and the engaging ~ ;
pro~ection 210, thereby causing a lipstick 265 to pro~ect : : - ~ .:
from the casing.
This conventional cosmetic material casing is useful : :~ .. ::
because the rotary operation of the tubular body 201 moves both the llpstick 265 and the lid 242 so that the lipstick ~ ,'~, ' ::' 133196~
265 projects from the casing as the lid 242 is opened.
However, in this type of casing, a hinge 242a which is provided at the top edge of the screw tube 214 and to which the lid 242 is attached must be positioned in such a manner -that it protrudes outwardly beyond the top edge of the screw tube 214 in order to ensure that it does not obstruct the movement of the tubular body~201 and the inner tube 209. In addition to this protruberant structure of the hinge 242a, -the tail tube 203 also creates a protrusion in relation to the overall shape of the casing. Thus, there is a problem ;-~
of the appearance or the form of the casing being deteriorated contrary to the requirements for this kinds of cosmetic casing.
In the structure whereby the tail tube 220 is attached to the rear end of the screw tube 214, the inner and outer peripheral surfaces of these members repeatedly slide in contact with each other, and the appearance of the casing will be impared by scratches formed by this sliding on the outer peripheral surface of the rear end portion of the srew tube 214.
In addition, since the outer helical groove 221 and the engaging projection 238 which cooperate to retract the screw tube 214 are provided in a lower portion of the tubular body 201 while the inner tube 209 is disposed above the outer -~
helical groove 221, a large cavity formed below the inner ~ .
, 1 33~96 , .
tube 209 when the lipstick 365 is retracted, as shown in ~-Fig. 11, resulting in an increase in the overall length of :
the casing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Examples of the structure of the invention (1) Figs. 1 to 6 show a type of structure in accordance -with the present invention in which the tubular body is `~
advanced. In this example, the tubular member is illustrated as a guide tube 11, the tubular main body as a ':I.'~''"'''h~
holder guide tube 18, the longitudinal elongated aperture as a longitudinal slit 18b, the closed inner tube as a holder 20, the engaging projection as a second projection 21, and ;`
the inner helical groove as an inner screw groove 16B.
That is, the longitudinal slit 18b is formed in the holder guide tube 18, the hoIder 20 is fitted in the holder ~;~
guide tube 18 so that it can rotate in the longitudinal :
' ~7 ~ ~
., 133196~
direction while the second projection provided on the holder 20 is projected to the outside of the holder guide tube 18.
At the same time, a screw tube 16 is rotatably fitted around the holder guide tube 18, and the second projection 21 of the holder 20 is fitted in the internal screw groove 16B
formed in the screw tube 16 so that the holder 20 can be lifted by an operation of rotating the screw tube 16 in one ;
direction. The guide tube 11 which is fixed to the holder guide tube 18 is fitted around the screw tube 16 so that the screw tube 16 can rotate relative to the guide tube 11. A
lid 13 for closing the opening of the guide tube 11 is pivotally mounted while being urged by a spring 14 in a direction such that it closes the opening. The arrangement is such that when the holder 20 is moved toward the opening of the guide tube 11 by the rotation of the screw tube 16, the screw tube 16 advances beyond the top end of the guide tube 11; and the lid 13 is moved in the direction of the lower end of the casing relative to the screw tube 16, the inner surPace of the lid 13 contacting the top end of the screw tube 16 to turn and open the lid 13.
This construction will be described below in further detail. This example of the casing has an outer rear tube~ ~;
lOB which is fitted on and fixed to the outer peripheral surface of a base end portion of the guide tube 11, and an outer head tube lOA which is rotatably fitted around the ~, :' -8 - - ~
,' ,''., 133196~
outer peripheral surface of a top portion of the quide tube 11. .
The lid 13 urged by the spring 14 in the lid opening direction is attached to the outer head tube lOA in the vicinity of the top opening edge thereof, and the screw tube 16 is fitted in the guide tube 11 so that it can slide on the inner peripheral surface of the guide tube in the axial direction and can rotate in the peripheral direction.
The screw tube 16 rotates integrally with the outer head tabe lOA while sliding therein in the axial directlon. -~
An outer screw groove 16A is formed in the outer peripheral surface of the screw tube 16, and an outer horizontal groove 16C is formed in the outer peripheral surface of the base ~ ,s, end portion of the screw tube 16 so as to connect to the outer screw groove 16A.
A first pro~ection piece 17 is provided in the inner peripheral surface of the guide tube 11 so as to protrude. ` ~ :
beyond this surface. The first projection piece 17 is ~ .
engaged with the outer screw groove 16A. The first projectlon piece 17 functions to advance the screw tube 16 in response to initial rotation of ~he outer rear tube lOB.
The inner screw groove 16B i9 formed in the inner perlpheral surface of the screw tube 16, and an inner ~
horizontal groove 16D is formed in the inner peripheral :
surface of the base end portion of the screw tube 16 so as ~ :
":'''''", ';; ~ . ':~ :
- 9 ~ "."` :"
: :, ~ ,:, 133~9~
to connect to the inner screw groove 16B.
The holder guide tube 18 is fitted on the inner -peripheral surface of the screw tube 16 so that it can ;~
rotate in the peripheral direction but cannot move in the axial direction. The longitudinal slit 18b is formed in the -~
holder guide tube 18 so as to extend in the axial direction ~--thereof.
The holder guide tube 18 is capable of rotating integrally with the outer rear tube lOB and sliding therein in the axial direction at the same time. The holder 20 that supports a stick of cosmetic material 19 is slidably fitted on the inner peripheral surface of the holder guide tube 18.
:
The second projection 21 formed on the outer peripheral surface of the holder 20 passes through the longitudinal ;
slit 18b of the holder guide tube 18 and engages with the inner screw groove 16B of the screw tube 16.
The holder guide tube 18 and the holder 20 are integrally rotated relative to the outer head tube lOA and the screw tube 16 by the initial rotation of the outer rear tube lOB. As the screw tube 16 thereby advances inside the guide tube 11, the top end of the screw tube 16 is brought into contact with the lid 13 and opens the same against the force of the spring 1~.
During this operation, the second projection 21 of the holder 20 moves in the inner horizontal groove 16D in the : ' , ' - 1 0 - ,",,, ,,,;, 133~965 inner surface of the screw tube 16 to the starting end of :
the inner screw groove 16B. --AS the outer rear tube lOB further rotates after the initial rotation, the guide tube 11 and the holder guide -tube 18 are thereby rotated integrally relative to the screw ;~
tube 16, and the holder 20 further moves forward from the - ; ;~:
advanced position while being guided along the longitudinal :
slit 18b by the second projection 21 moving in the inner screw groove 16B, thereby protruding the cosmetic materlal ~ :
l9 out of the holder guide tube 18. .
During this operation, the first projection piece 17 exits out of the terminal end of the outer screw groove 16A
and then moves in the outer horizontal groove 16C, thereby allowing the guide tube 11 to be rotated relative to the screw tube 16. ;
~2) Next, a type of structure in which the lid recedes to open will be described below with reference to Figs. 7 to 10. An elongated aperture 102 is formed in a tubular main body 101 so as to extend in the axial direction thereof. A
closed inner tube 109 is fitted in the tubular main body 101 so that it can slide thereln in the axial direction while an ~ ~
engaging projection 110 formed on the inner tube 109 is ~ ~.
projected to the outside of the tubular main body 101 through the elongated aperture 102. A screw tube 114 is .
rotatably fitted around the tubular main body 101, and the ~33~965 ::
' ': ' ' engaging projection of the inner tube 109 is fitted in an inner screw groove 115 so that the inner tube 109 can be lifted as the screw tube 114 rotates in one direction. A ~ ~
tubular member 126 which is fixed to the tubular main body -126 is fitted around the screw tube 114 so that the screw tube 114 can rotate relative to the tubular member 126. A
slidable plate 136 is fitted to a longitudinal slide groove 128 formed in the tubular member 126 so that it can move in ~1 the axial direction thereof. An engaging projection 138 `
formed on the slidable plate 136 ls fitted in an outer helical slit 121 provided on the outside of the screw tube 119, thereby enabling the slidable plate 136 to move downward as the screw tube 114 rotates in one direction. A
lid 142 for closing the opening of the tubular member 126 is -pivotally attached to an upper portion of the slidable plate 136. The arrangement is such that as the slidable plate 136 is moved downward, the inner surface of the lid 142 is brought into contact with the upper end of the casing, thereby turning and opening the lid 142. The lld 142 is urged by a spring 143 in the direction of closing movement. `~
From the state in which the lid 142 is closed as shown in Fig. 7, the casing is operated to open the lid 142 and protrude the cosmetic material as described below. The screw tube 114 is rotated in one direction while the tubular member 126 is held so as to be stopped from rotating (in the ~ ~;;',. .',:
1331 ~
illustrated example, an outer head tube 148 which is formed separately from the tubular member 126 and which is mounted ; . ~
on the outside thereof is held instead of the tubular member . .
126). (In the illustrated example, a skirt tube 155 is fixed on the outside of the screw tube 114, and a lower outer tube 161 is fixed on the outside of the skirt tube 161.
Therefore the lower outer tube 161 is rotated counterclockwise.) In response to this rotation, the slidable plate 136 is moved downward by a force downwardly applied to its engaging pro~ection 138 fitted in the outer helical slit 121. The inner surface of the lid 142 pivotally attached to the upper portion of the slidable plate 136 is thereby brought into contact with the upper end ~ :
of the casing, namely, the upper end of one of the tabular main body lO1, the tubular member 126 and the upper outer tube 148, and the lid 142 is thereafter opened against the urging force of the spring 143.
At the same time, the inner tube lO9 having its `~
engaging pro~ection llO fitted in the inner screw groove 115 .
of the screw tube 114 is lifted by the cooperation of the .
inner screw groove 115 and the elongated aperture 102 of the ;~
tubular main body 101 as the screw tube 114 rotates in one i ...... .
direction, thereby protruding out of the tubular member 126 ~:``. .

above-described constructions will be described below.
<Embodiment 1>
Figs. 1 to 6 shows an embodiment in which the casing has the type of structure described in ~
Referring first to Figs. 1 and 2, the head portion 10A
and the rear portion 10B of an outer tube assembly 10 have equal outside diameters and have outer surfaces flush with each other. The head and rear portions 10A and 10B are rotatable~relative to each other about the same axis while being interconnected by the guide tu~e 11 disposed inside the outer tube assembly 10. That is, the outer rear tube 10B closed at its bottom is fitted on and fixed to the outer peripheral surface of the guide tube 11, and the outer head tubeJ10A is connected by a ring 12 to the guide tube 11 so that it can rotate around the outer peripheral surface of the guide tube 11 while bordering a collar portion lla:
formed on the guide tube 11. A longitudinal slit llb is ~ormed in the guide tube 11 so as to extend from the base : ~ .. : .: :
end of the guide tube 11 in the axial direction thereof.
An attachment tube 15 is fitted in the top opening of ~ ~;
the outer head tube 10A, and the lid 13 is pivotally attached to the attachment tube 15 while being urged by a pair of torsion coil springs 19 in a direction such that it closes the top opening. One ends 14a of the springs 19 are embedded in the lid 13 while the other ends 14b are ~ :' -14 - ~ ;
,~.... ... , . :. ~ . . - , . ., ~ , ~333~
connected to each other and are inserted in a U-shaped attachment recess 15a formed in the outer peripheral surface of a top portion of the attachment tube 15. Th recess 15a is covered with the outer head tube lOA, thereby supporting the pair of springs 14. The coil ends 14b themselves have resiliency and inwardly urge the coiled portions 14c of the torsion coil springs 14 so that the rear end surface of the lid 13 in the closed state 1 is normally flush with the outer surface of the outer head tube lOA without outwardly -protruding therebeyond and that, in this state, the coil portions 14 do not protrude beyond these surfaces. When the lid 13 is opened, the ends 14 of the torsion coil springs 14 ::, . , : ~
are resiliently bent so that the coil portions are displaced ~
outwardly. -` ;
The screw tube 16 are fitted on the inner peripheral surface of the guide tube 11 so as that it can slide in the ~ `
axial direction and can rotate in the circumferential ~: :: .:, .:,...
direction. A guide groove 16f is formed in the outer : ~ `
peripheral surface of the screw tube 16 from the top to an intermediate portion of this tube, and a guide projection 16g formed on the inner surface of the attachment tube 15.
, Consequently, the screw tube 16 can rotate integrally with the outer top tube lOA and can slide in the axial direction inside the attachment tube 1, namely, the outer head tube ::
lOA.

The outer helical groove 16A is formed in the outer peripheral surface of the screw tube 16. As is clear from ~;
Fig. 2, the outer helical groove 16A is formed in such a manner that it slantingly extends downwardly from its top end 16a or starting end on the side of the top end of the screw tube 16 to a terminal end in the base end portion of the screw tube 16. The outer horizontal groove 16C is , formed in the outer peripheral surface of the base end portion of the screw tube 16 so that it extends continuously from the terminal end of the outer screw groove 16A in the circumferential direction to an extent generally corresponding to one circle.
The first projection piece 17 which is fixed on the guide tube 11 and which inwardly protrudes beyond the inner peripheral surface of the guide tube 11 is engaged with the outer helical groove 16A. As t~le first projection piece 17 is rotated integrally with the outer rear tube lOB, the ;~
screw tube 16 advances through a linear stroke corresponding ~: : ,:- : , :
to the distance between its top end 16a and the outer horizontal groove 16C.
The inner helical groove 16B is formed in the inner ~ , :"~ ~:
peripheral surface of the screw tube 16. The inner helical ~ ~
:::::
groove 16B connnects at its end on the side of the base end of the screw tube 16 to the inner horizontal groove 16D
which is formed in the inner peripheral surface of the base '' ,"`' ,:' : ' ':

end portion of the screw tube 16 and which extends in the circumferential direction to an extent generally corresponding to one circle.
The holder guide tube 18 is rotatably fitted on the inner periphery of the screw tube 1. The holder guide tube 18 has a guide lug 18a projecting from its bottom portion.
The guide lug 18a is engaged with the longitudinal slit llb -, of the guide tube 11 so as to guide the movement in the ;~ ~
.
axial direction of the holder 18 and enables the holder 18 to be rotated integrally with the guide tube 11 and the --outer rear tube lOB. The holder guide tube 18 is stopped from sliding in the axial direction of the screw tube 16 by the engagement of engaging pawls 18e and 18f. The longitudinal slit 18b is formed in the peripheral wall of the holder guide tube 18. Horizontal slits 18c and 18d are ` ``
formed at the top and base ends of the longitudinal slit 18b, respectively, as shown in Fig. 4. The sum of the length of horizontal slits 18c or 18d and the length of the outer hori20ntal groove 16C or the inner horizontal groove 16D corresponds to the circumference of the screw tube 16 on the outer peripheral surface or the inner peripheral surface thereof.
The holder 20 which retains a stick of cosmetic .:::
material 19 is fitted on the inner peripheral surface of the holder guide tube 18 so that it can move in the axial direction. The second projection 21 protrusively formed on the outer peripheral surface of the holder 20 is brought into engagement with the inner helical groove 16B of the screw tube 16 through the longitudinal slit 18b of the holder guide tube 18.
Next, the operation and effect of this embodiment will be described below.
In an initial state shown in Fig. 1, the first projection piece 17 is located at the starting end of the - `~
~ :.
outer helical groove 16A of the screw tube 16 while the ` -second projection 21 of the holder 20 is in contact with a terminal edge 16e of the inner horizontal groove I6 by -passing through the horizontal slit 18d.
As shown in Fig. 15, as the outer rear tube lOB is -rotated in an initial stage while the outer head tube lOA is held fixedly, the outer rear tube lOB, the guide tube 11, the holder guide tube 18 and the holder 20 are integrally rotated relative to the screw tube 16 integrally connected to the outer head tube lOA by the attachment tube 15. The , :,:
first projection piece 17 is thereby moved downwardly in the outer helical groove 16A of the screw tube 16 from the top :-~
end 16a along the sloping surface. Relative to this movement, the screw tube 16 advances toward the top of Fig.
:
15 to a predetermined extent in the guide tube 11 and in the ;~
outer head tube 12A.
:
: , , 133196~
During this forward movement of the screw tube 16, the top end of the screw tube 16 comes into contact with the : ends 14b of the torsion coil springs 14 from below so as to bend and displace the same. The coiled portions 14c of the : ~-:.,:: . :..
torsion coil springs 14 thereby;escape outward, and the lid 13 is opened by being moved upward against the force of the torsion coil springs 14. At the~same time, the holder guide .
tube 18 and the holder 20 also advance through the same :~

the elongated apertures 102 so as to inhibit the inner tube 109 from rotating.
The screw tube 119 is rotatably fitted around the tubular main body 101. The screw tube 114 has an engaging protrusion 16 formed on its outer suxface and a palr of :
inner screw grooyes 115 which are formed in its inner 13319~
surface and in which the engaging projections 110 of the inner tube 109 are fitted. The arrangement is such that as the screw tube 114 is rotated in one direction, the engaging projections 110 of the inner tube 109 are moved upward by the inner screw grooves 115 and the elongated apertures 102 - -so that the inner tube 109 is lifted. An outer screw tube - ;~

, COSMETIC CASING CAPABLE OF PROTRUDING COSMETIC MATERIAL
BACKGROUND OF THE INVENTION
This invention relates to a casing capable of protruding a cosmetic material such as lipstick contained in the casing.
Conventionally, an ordinary casing capable of putting : .. .....
out a cosmetic material such as lipstick contained therein has a structure wherein a stick of rouge is protruded from the body of the casing by a certain kind of prot~ruding operation, e.g., rotation of a member on the casing body.
It is convenient to design such an article so that the cap is automatically opened and closed in a linked relatioship with the protrudlng operation in order to eliminate the need for a separate operation of removing the cap. ~ ~;
In consideration of this point, the applicant of the present invention has proposed a stick-type cosmetic materlal casing which is disclosed in Japanese Utility Model Laid-Open No. 58-88914 and has a structure such as that shown in Figs. 11 and 12.
This casing is construc~ed as described below. A lid 242 is attached to the upper end of a screw tube 219. The screw tube 214 has an inner helical groove 215 formed in its inner peripheral surface and an engaging pro]ection 238 formed on the inner peripheral surface of its lower portion.
.
~ A tubular body 201 is fitted in the screw tube 214. The ` 133~96~ ;
tubular body 201 has an elongated aperture 202 extending in the axial direction and an outer helical groove 221 formed in the outer peripheral surface of its lower portion. The engaging projection 238 of the screw tube 214 is fitted in the outer helical groove 221.~ A closed inner tube 209 is fitted in the tubular body 201 while an engaging projection 210 formed on the inner tube 209 is fitted in the inner helical groove 215 of the screw tube 214 through the elongated`aperture 202 of the tubular body 201. A tail tube 220 is fitted on and fixed to the outer peripheral surface of the rear end portion of the tubular body 201.
As the tubular body 201 is rotated by an operation of turning the tail tube 220 while supporting the screw tube 214, the screw tube 214 is moved downward by the cooperation of the outer helical groove 221 and the engaging projection , : ::
238 and the inner surface of the lid 292 is brought into contact with the upper end of the tubular body 201 whereby the lid 242 is turned and opened, as shown in Fig. 12. At the same time, the inner tube 209 is moved upward by the cooperation of the inner helical groove 215 and the engaging ~ ;
pro~ection 210, thereby causing a lipstick 265 to pro~ect : : - ~ .:
from the casing.
This conventional cosmetic material casing is useful : :~ .. ::
because the rotary operation of the tubular body 201 moves both the llpstick 265 and the lid 242 so that the lipstick ~ ,'~, ' ::' 133196~
265 projects from the casing as the lid 242 is opened.
However, in this type of casing, a hinge 242a which is provided at the top edge of the screw tube 214 and to which the lid 242 is attached must be positioned in such a manner -that it protrudes outwardly beyond the top edge of the screw tube 214 in order to ensure that it does not obstruct the movement of the tubular body~201 and the inner tube 209. In addition to this protruberant structure of the hinge 242a, -the tail tube 203 also creates a protrusion in relation to the overall shape of the casing. Thus, there is a problem ;-~
of the appearance or the form of the casing being deteriorated contrary to the requirements for this kinds of cosmetic casing.
In the structure whereby the tail tube 220 is attached to the rear end of the screw tube 214, the inner and outer peripheral surfaces of these members repeatedly slide in contact with each other, and the appearance of the casing will be impared by scratches formed by this sliding on the outer peripheral surface of the rear end portion of the srew tube 214.
In addition, since the outer helical groove 221 and the engaging projection 238 which cooperate to retract the screw tube 214 are provided in a lower portion of the tubular body 201 while the inner tube 209 is disposed above the outer -~
helical groove 221, a large cavity formed below the inner ~ .
, 1 33~96 , .
tube 209 when the lipstick 365 is retracted, as shown in ~-Fig. 11, resulting in an increase in the overall length of :
the casing.

as to turn and open by contacting at its inner surface with an upper end portion of the casing.
Receding of the lid relative to the screw tube means that at least one of the screw tube and the lid is moved.
This operation is enabled by an arrangement wherein an engaging projection provided on the tubular member is fitted : . :
in a screw groove formed in the outer surface of the screw tube; and an engaging projectlon formed on the tubular main ;
body is fitted in an elongated groove formed in the inner surface of the tubular member; the screw tube is capable of sliding together with the tubular main body to an extent corresponding to the length of the elongated groove in the ... .

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Examples of the structure of the invention (1) Figs. 1 to 6 show a type of structure in accordance -with the present invention in which the tubular body is `~
advanced. In this example, the tubular member is illustrated as a guide tube 11, the tubular main body as a ':I.'~''"'''h~
holder guide tube 18, the longitudinal elongated aperture as a longitudinal slit 18b, the closed inner tube as a holder 20, the engaging projection as a second projection 21, and ;`
the inner helical groove as an inner screw groove 16B.
That is, the longitudinal slit 18b is formed in the holder guide tube 18, the hoIder 20 is fitted in the holder ~;~
guide tube 18 so that it can rotate in the longitudinal :
' ~7 ~ ~
., 133196~
direction while the second projection provided on the holder 20 is projected to the outside of the holder guide tube 18.
At the same time, a screw tube 16 is rotatably fitted around the holder guide tube 18, and the second projection 21 of the holder 20 is fitted in the internal screw groove 16B
formed in the screw tube 16 so that the holder 20 can be lifted by an operation of rotating the screw tube 16 in one ;
direction. The guide tube 11 which is fixed to the holder guide tube 18 is fitted around the screw tube 16 so that the screw tube 16 can rotate relative to the guide tube 11. A
lid 13 for closing the opening of the guide tube 11 is pivotally mounted while being urged by a spring 14 in a direction such that it closes the opening. The arrangement is such that when the holder 20 is moved toward the opening of the guide tube 11 by the rotation of the screw tube 16, the screw tube 16 advances beyond the top end of the guide tube 11; and the lid 13 is moved in the direction of the lower end of the casing relative to the screw tube 16, the inner surPace of the lid 13 contacting the top end of the screw tube 16 to turn and open the lid 13.
This construction will be described below in further detail. This example of the casing has an outer rear tube~ ~;
lOB which is fitted on and fixed to the outer peripheral surface of a base end portion of the guide tube 11, and an outer head tube lOA which is rotatably fitted around the ~, :' -8 - - ~
,' ,''., 133196~
outer peripheral surface of a top portion of the quide tube 11. .
The lid 13 urged by the spring 14 in the lid opening direction is attached to the outer head tube lOA in the vicinity of the top opening edge thereof, and the screw tube 16 is fitted in the guide tube 11 so that it can slide on the inner peripheral surface of the guide tube in the axial direction and can rotate in the peripheral direction.
The screw tube 16 rotates integrally with the outer head tabe lOA while sliding therein in the axial directlon. -~
An outer screw groove 16A is formed in the outer peripheral surface of the screw tube 16, and an outer horizontal groove 16C is formed in the outer peripheral surface of the base ~ ,s, end portion of the screw tube 16 so as to connect to the outer screw groove 16A.
A first pro~ection piece 17 is provided in the inner peripheral surface of the guide tube 11 so as to protrude. ` ~ :
beyond this surface. The first projection piece 17 is ~ .
engaged with the outer screw groove 16A. The first projectlon piece 17 functions to advance the screw tube 16 in response to initial rotation of ~he outer rear tube lOB.
The inner screw groove 16B i9 formed in the inner perlpheral surface of the screw tube 16, and an inner ~
horizontal groove 16D is formed in the inner peripheral :
surface of the base end portion of the screw tube 16 so as ~ :
":'''''", ';; ~ . ':~ :
- 9 ~ "."` :"
: :, ~ ,:, 133~9~
to connect to the inner screw groove 16B.
The holder guide tube 18 is fitted on the inner -peripheral surface of the screw tube 16 so that it can ;~
rotate in the peripheral direction but cannot move in the axial direction. The longitudinal slit 18b is formed in the -~
holder guide tube 18 so as to extend in the axial direction ~--thereof.
The holder guide tube 18 is capable of rotating integrally with the outer rear tube lOB and sliding therein in the axial direction at the same time. The holder 20 that supports a stick of cosmetic material 19 is slidably fitted on the inner peripheral surface of the holder guide tube 18.
:
The second projection 21 formed on the outer peripheral surface of the holder 20 passes through the longitudinal ;
slit 18b of the holder guide tube 18 and engages with the inner screw groove 16B of the screw tube 16.
The holder guide tube 18 and the holder 20 are integrally rotated relative to the outer head tube lOA and the screw tube 16 by the initial rotation of the outer rear tube lOB. As the screw tube 16 thereby advances inside the guide tube 11, the top end of the screw tube 16 is brought into contact with the lid 13 and opens the same against the force of the spring 1~.
During this operation, the second projection 21 of the holder 20 moves in the inner horizontal groove 16D in the : ' , ' - 1 0 - ,",,, ,,,;, 133~965 inner surface of the screw tube 16 to the starting end of :
the inner screw groove 16B. --AS the outer rear tube lOB further rotates after the initial rotation, the guide tube 11 and the holder guide -tube 18 are thereby rotated integrally relative to the screw ;~
tube 16, and the holder 20 further moves forward from the - ; ;~:
advanced position while being guided along the longitudinal :
slit 18b by the second projection 21 moving in the inner screw groove 16B, thereby protruding the cosmetic materlal ~ :
l9 out of the holder guide tube 18. .
During this operation, the first projection piece 17 exits out of the terminal end of the outer screw groove 16A
and then moves in the outer horizontal groove 16C, thereby allowing the guide tube 11 to be rotated relative to the screw tube 16. ;
~2) Next, a type of structure in which the lid recedes to open will be described below with reference to Figs. 7 to 10. An elongated aperture 102 is formed in a tubular main body 101 so as to extend in the axial direction thereof. A
closed inner tube 109 is fitted in the tubular main body 101 so that it can slide thereln in the axial direction while an ~ ~
engaging projection 110 formed on the inner tube 109 is ~ ~.
projected to the outside of the tubular main body 101 through the elongated aperture 102. A screw tube 114 is .
rotatably fitted around the tubular main body 101, and the ~33~965 ::
' ': ' ' engaging projection of the inner tube 109 is fitted in an inner screw groove 115 so that the inner tube 109 can be lifted as the screw tube 114 rotates in one direction. A ~ ~
tubular member 126 which is fixed to the tubular main body -126 is fitted around the screw tube 114 so that the screw tube 114 can rotate relative to the tubular member 126. A
slidable plate 136 is fitted to a longitudinal slide groove 128 formed in the tubular member 126 so that it can move in ~1 the axial direction thereof. An engaging projection 138 `
formed on the slidable plate 136 ls fitted in an outer helical slit 121 provided on the outside of the screw tube 119, thereby enabling the slidable plate 136 to move downward as the screw tube 114 rotates in one direction. A
lid 142 for closing the opening of the tubular member 126 is -pivotally attached to an upper portion of the slidable plate 136. The arrangement is such that as the slidable plate 136 is moved downward, the inner surface of the lid 142 is brought into contact with the upper end of the casing, thereby turning and opening the lid 142. The lld 142 is urged by a spring 143 in the direction of closing movement. `~
From the state in which the lid 142 is closed as shown in Fig. 7, the casing is operated to open the lid 142 and protrude the cosmetic material as described below. The screw tube 114 is rotated in one direction while the tubular member 126 is held so as to be stopped from rotating (in the ~ ~;;',. .',:
1331 ~
illustrated example, an outer head tube 148 which is formed separately from the tubular member 126 and which is mounted ; . ~
on the outside thereof is held instead of the tubular member . .
126). (In the illustrated example, a skirt tube 155 is fixed on the outside of the screw tube 114, and a lower outer tube 161 is fixed on the outside of the skirt tube 161.
Therefore the lower outer tube 161 is rotated counterclockwise.) In response to this rotation, the slidable plate 136 is moved downward by a force downwardly applied to its engaging pro~ection 138 fitted in the outer helical slit 121. The inner surface of the lid 142 pivotally attached to the upper portion of the slidable plate 136 is thereby brought into contact with the upper end ~ :
of the casing, namely, the upper end of one of the tabular main body lO1, the tubular member 126 and the upper outer tube 148, and the lid 142 is thereafter opened against the urging force of the spring 143.
At the same time, the inner tube lO9 having its `~
engaging pro~ection llO fitted in the inner screw groove 115 .
of the screw tube 114 is lifted by the cooperation of the .
inner screw groove 115 and the elongated aperture 102 of the ;~
tubular main body 101 as the screw tube 114 rotates in one i ...... .
direction, thereby protruding out of the tubular member 126 ~:``. .

above-described constructions will be described below.
<Embodiment 1>
Figs. 1 to 6 shows an embodiment in which the casing has the type of structure described in ~
Referring first to Figs. 1 and 2, the head portion 10A
and the rear portion 10B of an outer tube assembly 10 have equal outside diameters and have outer surfaces flush with each other. The head and rear portions 10A and 10B are rotatable~relative to each other about the same axis while being interconnected by the guide tu~e 11 disposed inside the outer tube assembly 10. That is, the outer rear tube 10B closed at its bottom is fitted on and fixed to the outer peripheral surface of the guide tube 11, and the outer head tubeJ10A is connected by a ring 12 to the guide tube 11 so that it can rotate around the outer peripheral surface of the guide tube 11 while bordering a collar portion lla:
formed on the guide tube 11. A longitudinal slit llb is ~ormed in the guide tube 11 so as to extend from the base : ~ .. : .: :
end of the guide tube 11 in the axial direction thereof.
An attachment tube 15 is fitted in the top opening of ~ ~;
the outer head tube 10A, and the lid 13 is pivotally attached to the attachment tube 15 while being urged by a pair of torsion coil springs 19 in a direction such that it closes the top opening. One ends 14a of the springs 19 are embedded in the lid 13 while the other ends 14b are ~ :' -14 - ~ ;
,~.... ... , . :. ~ . . - , . ., ~ , ~333~
connected to each other and are inserted in a U-shaped attachment recess 15a formed in the outer peripheral surface of a top portion of the attachment tube 15. Th recess 15a is covered with the outer head tube lOA, thereby supporting the pair of springs 14. The coil ends 14b themselves have resiliency and inwardly urge the coiled portions 14c of the torsion coil springs 14 so that the rear end surface of the lid 13 in the closed state 1 is normally flush with the outer surface of the outer head tube lOA without outwardly -protruding therebeyond and that, in this state, the coil portions 14 do not protrude beyond these surfaces. When the lid 13 is opened, the ends 14 of the torsion coil springs 14 ::, . , : ~
are resiliently bent so that the coil portions are displaced ~
outwardly. -` ;
The screw tube 16 are fitted on the inner peripheral surface of the guide tube 11 so as that it can slide in the ~ `
axial direction and can rotate in the circumferential ~: :: .:, .:,...
direction. A guide groove 16f is formed in the outer : ~ `
peripheral surface of the screw tube 16 from the top to an intermediate portion of this tube, and a guide projection 16g formed on the inner surface of the attachment tube 15.
, Consequently, the screw tube 16 can rotate integrally with the outer top tube lOA and can slide in the axial direction inside the attachment tube 1, namely, the outer head tube ::
lOA.

The outer horizontal groove 16C is , formed in the outer peripheral surface of the base end portion of the screw tube 16 so that it extends continuously from the terminal end of the outer screw groove 16A in the circumferential direction to an extent generally corresponding to one circle.
The first projection piece 17 which is fixed on the guide tube 11 and which inwardly protrudes beyond the inner peripheral surface of the guide tube 11 is engaged with the outer helical groove 16A. As t~le first projection piece 17 is rotated integrally with the outer rear tube lOB, the ;~
screw tube 16 advances through a linear stroke corresponding ~: : ,:- : , :
to the distance between its top end 16a and the outer horizontal groove 16C.
The inner helical groove 16B is formed in the inner ~ , :"~ ~:
peripheral surface of the screw tube 16. The inner helical ~ ~

The guide lug 18a is engaged with the longitudinal slit llb -, of the guide tube 11 so as to guide the movement in the ;~ ~
.
axial direction of the holder 18 and enables the holder 18 to be rotated integrally with the guide tube 11 and the --outer rear tube lOB. The holder guide tube 18 is stopped from sliding in the axial direction of the screw tube 16 by the engagement of engaging pawls 18e and 18f. The longitudinal slit 18b is formed in the peripheral wall of the holder guide tube 18. Horizontal slits 18c and 18d are ` ``
formed at the top and base ends of the longitudinal slit 18b, respectively, as shown in Fig. 4. The sum of the length of horizontal slits 18c or 18d and the length of the outer hori20ntal groove 16C or the inner horizontal groove 16D corresponds to the circumference of the screw tube 16 on the outer peripheral surface or the inner peripheral surface thereof.
The holder 20 which retains a stick of cosmetic .:::
material 19 is fitted on the inner peripheral surface of the holder guide tube 18 so that it can move in the axial direction. The second projection 21 protrusively formed on the outer peripheral surface of the holder 20 is brought into engagement with the inner helical groove 16B of the screw tube 16 through the longitudinal slit 18b of the holder guide tube 18.
Next, the operation and effect of this embodiment will be described below.
In an initial state shown in Fig. 1, the first projection piece 17 is located at the starting end of the - `~
~ :.
outer helical groove 16A of the screw tube 16 while the ` -second projection 21 of the holder 20 is in contact with a terminal edge 16e of the inner horizontal groove I6 by -passing through the horizontal slit 18d.
As shown in Fig. 15, as the outer rear tube lOB is -rotated in an initial stage while the outer head tube lOA is held fixedly, the outer rear tube lOB, the guide tube 11, the holder guide tube 18 and the holder 20 are integrally rotated relative to the screw tube 16 integrally connected to the outer head tube lOA by the attachment tube 15. The , :,:
first projection piece 17 is thereby moved downwardly in the outer helical groove 16A of the screw tube 16 from the top :-~
end 16a along the sloping surface. Relative to this movement, the screw tube 16 advances toward the top of Fig.
:
15 to a predetermined extent in the guide tube 11 and in the ;~
outer head tube 12A.
:
: , , 133196~
During this forward movement of the screw tube 16, the top end of the screw tube 16 comes into contact with the : ends 14b of the torsion coil springs 14 from below so as to bend and displace the same. The coiled portions 14c of the : ~-:.,:: . :..
torsion coil springs 14 thereby;escape outward, and the lid 13 is opened by being moved upward against the force of the torsion coil springs 14. At the~same time, the holder guide .
tube 18 and the holder 20 also advance through the same :~
distance by~following the 5crew tube 16. - :~
During this operation, the second projection 21 of the .
holder 20 moves in the inner horizontal groove 16D formed in the inner surface of the~ screw tube 16 to the starting end of the inner helical groove 16B, exits out of the horizontal "- -slit 18d and reaches the base end of the longitudinal slit 18b.
As shown in Fig. 6, to perform the operation of :: ~... -: ~
protruding the cosmetic material 19, the outer rear tube 10B
iS rotated in the sate where the lid 13 has been opened by the initial rotation of the outer rear tube lOB, thereby integrally rotating the guide tube 11 and the holder guide tube 18 relative to the screw tube 16. This rotation :
applies an upward force to the second projection 21 of the :.
'.:: . ~' holder in engagement with the inner helical groove 16B, and : :~
:. ~
the second projection 21 is thereby lifted while being guided along the longitudinal slit 18b of the holder guide ~' i :
~331~6~
tube 18 so that the holder is further moved from the advanced position, thereby protruding the cosmetic material 19 out of the holder guide tube 18.
During thls operation, the first projection piece 17 exits out of the terminal end of the outer helical groove ~ ~
16A and then moves in the outer horizontal groove 16C, ;
thereby allowing the guide tube 11 to rotate relative to the screw tube 16. After the first pro~jection piece 17 has come ;
into contact with a terminal edge 16b of the outer horizontal groove 16C, the second projection 18a of the holder guide tube 18 which has reached the top end of the longitudinal slit 18b enters the horizontal slit 18c.
The operation of retracting the cosmetic material 19 is performed in accordance with the procedure reverse to the above.
As described above, the overall outside configuration oP the cosmetic material casing constituted by the outer head tube lOA, the outer rear tube lOB and the lid 13 in accordance with the present invention is simple and the outside surfaces thereoP are Pormed without any protrusions.
Thus, the caslng oP the present invention is improved in the appearance and form to satisPy requirements Por cosmetic casing~
The above-described structure enables the protruding operation to be smoothly performed and enables the lid 13 to ~ ' ' .
~ :: ' .~ ' ' ' - 13 31 9 6 ~ ~
be automatically opened or closed in a linked relationship -with the operation of protruding or retracting the cosmetic .
matexial 19 or the lipstick, thus making the casing :~ :
convenient. ;~
<Embodiment 2>
In this embodiment, the casing has the type of ;~
structure described in (2). :
The tubular main body 101 has an upper annular projection 103 and a lower annular~projection 105. An , :: ~
engagement recess 104 is formed in the upper annular projection 103. A pair of elongated apertures 102 are - ~.
formed in the cylindrical portion of the tubular main body 101. Each elongated aperture 102 has left and right horizontal extensions formed at its upper and lower :
portions.
The inner closed tube 109 is fitted in the tubular main ~ -body 101 so that it can slide in the axial direction while ~ ~.
engaging projections 110 formed on the inner tube 109 projects to the outside of the tubular main body 101 through .: ::

The screw tube 119 is rotatably fitted around the tubular main body 101. The screw tube 114 has an engaging protrusion 16 formed on its outer suxface and a palr of :
inner screw grooyes 115 which are formed in its inner 13319~
surface and in which the engaging projections 110 of the inner tube 109 are fitted. The arrangement is such that as the screw tube 114 is rotated in one direction, the engaging projections 110 of the inner tube 109 are moved upward by the inner screw grooves 115 and the elongated apertures 102 - -so that the inner tube 109 is lifted. An outer screw tube - ;~
120 in which the outer helical slit 121 is formed is fitted around a head portion of the screw tube 114, and the ~ -engaging protrusion 16 of the screw tube 114 is fitted in a longitudinal slit 122 of the outer screw tube 120, thereby inhibitlng the outer screw tube 120 from rotating relative -~
to the screw tube 114.
The tubular member 126 is fitted around the screw tube 114 so that it can rotate relative to the tubular member -:, ,:
126. The tubular member 126 is fixed on the tubular main body 101 by engaging its inner engaging protrusion 130 formed on its inner surface with the engagement recess 104 of the tubular main body 101. The tubular member 126 has an upper annular projection 127, an outer fitting protrusion : : : .
131, an end cutout 129 and a screw tube fitting portion 132 ;
formed over its inner surface except for an upper portion.
The tubular member 126 also has the longitudinal slide groove 128 formed on the outside of the end cutout 129. The longitudinal slide groove 128 are formed as an aperture over the area facing the screw tube fitting portion 132. ;

such that as the screw tube 114 is rotated in one direct~ion, the outer helical slit 121 applies a downward force to the ~ :
engaglng projection 138 of the slidable plate 136, thereby ;~
moving the slidable plate 136 downward.
The outer head tube 148 is fltted around the tubular main body 126; a fitting recess 50 formed in the outer head tube 148 is fitted to the outer fitting protrusion 131 of ~ :
the tubular member 126; and portions of the upper head tube ~ ~
