Slide tye cosmetic stick vessels

Description

BACKGROUND OF THE INVENTION

Field of the Invention

[0001] The invention relates to an improved slide type vessel for a cosmetic stick such as lipstick. More particularly the present invention relates to a novel slide type cosmetic stick vessel comprising a cosmetic stick container portion in which a cosmetic stick slides and is contained and a slide portion which slides in the container portion in the longitudinal direction.

Description of the Prior Art

[0002] Recently, slide type cosmetic stick vessels having a smaller size and a shape suitable for handling are desired. However, a vessel in which the size is simply diminished is defective in that the operation of extending a cosmetic stick becomes difficult and the vessel is difficult to hold during use.

[0003] For eliminating the above disadvantage, Japanese Examined Patent Publication No. 50-31075 proposes a cosmetic stick vessel which is extendable to a length suitable for application of cosmetic when the cosmetic stick is in use and the vessel is contracted when the cosmetic stick is contained. However, this structure is complicated and the number of parts is increased, and the manufacturing cost is inevitably increased. Moreover, since the mechanism for extending the cosmetic stick is arranged in series to the mechanism for extending and contracting the vessel, the length of the cosmetic stick to be contained in the vessel is relatively short as compared with the length of the vessel in the contracted state.

[0004] DE-A-3,119,901 discloses a slide type cosmetic stick vessel comprising a middle cup for holding a cosmetic stick, which has an engaging projection formed on the outer wall thereof, a body cylinder having a longitudinal guide groove through which the engaging projection slides, a further cylinder fitted on the periphery of the body cylinder, said further cylinder having a first flight groove with which the engaging projection is engaged, and a cover cylinder in which the further cylinder is inserted and secured. However in this publication the cover cylinder is longitudinally fixed, with respect to the body of the vessel, and does not act as a "slide'portion" as in the present invention.

SUMMARY OF THE INVENTION

[0005] An object of the present invention is to eliminate the above defects of the conventional techniques.

[0006] The invention is characterised in that said cover cylinder has a second engaging projection formed on the outer wall of the lower portion thereof, a slide cylinder secured to the outer wall of the lower end of the body cylinder, said slide cylinder having a rotation-stopping piece formed on the outer wall thereof, an insert cylinder fitted to the outer, surface of the lower portion of the cover cylinder, said insert cylinder having a second flight groove with which the second engaging projection is engaged, one of said first and second flight grooves being right-handed and the other being left-handed, said insert cylinder also having a longitudinal engaging groove with which the rotation-stopping piece is slidably engaged; and a middle cylinder in which the insert cylinder is inserted and secured, wherein the middle cup and the slide cylinder are slidable longitudinally by rotating said cover cylinder with respect to said middle cylinder.

[0007] The above-mentioned insert cylinder and middle cylinder may optionally be integrally formed as a middle cylinder having said second flight groove provided on the inner circumferential wall thereof.

[0008] Optionally, the further cylinder and cover cylinder may be integrally formed as a threaded cylinder having said first flight groove formed on the inner circumferential wall thereof and having a second engaging projection formed on the outer wall of the lower portion thereof.

DESCRIPTION OF THE PREFERRED

EMBODIMENTS

[0010] Referring now to Figs. 1 through 4, a middle saucer 1 for holding a cosmetic stick A is a bottomed cylinder and an engaging projection 2 is formed on the outer wall thereof. A longitudinal guide groove 4 is formed on a body cylinder 3 in which the middle saucer 1 is slidably inserted, so that the engaging projection 2 slides through the longitudinal guide groove 4. A projection 5 is formed along the periphery of the top end of the body cylinder 3. A right-hand flight groove 7 is formed on a threaded cylinder 6 fitted to the periphery of the body cylinder 3. The threaded cylinder 6 is inserted and secured in the cover cylinder 8.

[0011] In the above-mentioned structure, the engaging projection 2 of the middle saucer 1 slides through the guide groove 4 of the body cylinder 3 and becomes engaged with the right-hand flight groove 7 of the threaded cylinder 6, and by this engagement and the rotation of the body cylinder, the cosmetic stick A is moved in the longitudinal direction. Thus, a portion for containing a cosmetic stick such as a lipstick in the body cylinder 3 is constructed.

[0012] A second engaging projection 9 is formed on the outer wall of the lower portion of the cover cylinder 8. A bottomed slide cylinder 10 is inserted and secured in the outer wall of the lower end portion of the body cylinder 3, and a rotation-stopping piece 11 is projected on the outer wall of the slide cylinder 10. An insert cylinder 12 is fitted on the periphery of the lower portion of the cover cylinder 8, and a left-hand flight groove 13 with which the second projection 9 of the cover cylinder 8 is engaged is formed on the insert cylinder 12 and a longitudinal engaging groove 14 with which the rotation-stopping piece 11 of the slide cylinder 10 is slidably engaged is also formed on the insert cylinder 12. Furthermore, the insert cylinder 12 is inserted and secured in a middle cylinder 15. The middle cylinder 15 is inserted and secured in a bottomed outer cylinder 16 and the top end periphery of the outer cylinder 16 is anchored on an anchoring projection 17 formed on the peripheral wall of the middle cylinder 15. A plurality of brackets 18 are projected on the middle cylinder 15 so that a topped cylindrical lid (not shown) is dismountably capped.

[0013] In the above-mentioned structure, the abovementioned cosmetic stick-containing portion is moved in the longitudinal direction by the slidable engagement of the second engaging projection 9 of the cover cylinder 8 with the left-hand flight groove 9 of the insert cylinder 12 and the rotation of the insert cylinder 12 inserted and secured in the middle cylinder 15. Thus, a slide portion for moving the cosmetic stick-containing portion in the longitudinal direction is constructed.

[0014] More specifically, by rotating the outer cylinder 16 while holding the cover cylinder 8, the middle cylinder 15, the insert cylinder 12 and the left-hand flight groove 13 of the insert cylinder 12 are turned. Since the second engaging projection 9 formed on the cover cylinder 8 is slidably engaged with the left-hand flight groove 13, the cover cylinder 8 is longitudinally moved with the rotation of the left-hand threaded groove 13. Since the rotation-stopping piece 11 projected on the slide cylinder 10 inserted and secured in the body cylinder 3 is slidably engaged with the engaging groove 14 of the insert cylinder 12, the body cylinder 3 is turned with the rotation of the insert cylinder 12. Since the engaging projection 2 formed on the middle saucer 1 holding the cosmetic stick A thereon pierces through the guide groove 4 of the body cylinder 3 and is slidably engaged with the right-hand flight groove 7 of the threaded cylinder 6, the middle cup 1 is longitudinally moved in the body cylinder 3 with the rotation of the body cylinder 3, whereby the cosmetic stick A is delivered out from the body cylinder 3 or retreated into the body cylinder 3.

[0015] As is apparent from the foregoing description, even if the slide type cosmetic stick vessel of the present invention has a short shape suitable for carrying, since the cover cylinder 8 having a length corresponding to the left-hand flight stroke is delivered out, the painting operation is facilitated. Moreover, since the threaded cylinder 6 of the cosmetic stick-containing portion is contained in the interior of the insert cylinder 12 of the slide portion for moving the cosmetic stick-containing portion in the longitudinal direction, the length of the vessel can be shortened to a length slightly longer than the length of the cosmetic stick. Accordingly, the cosmetic stick vessel of the present invention is very easy to handle and carry. Moreover, the number of constituent parts can be decreased and the manufacturing cost can be reduced.

[0016] According to another embodiment of the present invention, as shown in Fig. 5, a right-hand flight groove 7' with which the engaging projection 2 is engaged is formed on the inner circumferential wall of the threaded cylinder 6 and a second engaging projection (not shown) which is engaged with the left-hand flight groove 13 formed on.the insert cylinder 12 is formed on the outer wall of the lower portion of the threaded cylinder 6. In this embodiment, even if the cover cylinder 8 described above is omitted, a slide type cosmetic stick vessel having the same functions as those of the vessel of the first embodiment can be provided.

[0017] In a further embodiment of the present invention as shown in Figs. 6 and 7, the above- mentioned insert cylinder 12 and middle cylinder 15 are replaced by a middle cylinder 15' having two parallel left-hand flight groove 13' provided on the inner circumferential wall thereof. This embodiment will be described in detail below.

[0018] A middle saucer 1 for holding a cosmetic stick A is a bottomed cylinder and an engaging projection 2 is formed on the outer wall thereof. A longitudinal guide groove 4 is formed on a body cylinder 3 in which the middle saucer 1 is slidably inserted, so that the engaging projection 2 slides through the longitudinal guide groove 4. A projection 5 is formed along the periphery of the top end of the body cylinder 3. A right-hand flight groove 7-is formed on a threaded cylinder 6 fitted to the periphery of the body cylinder 3. The threaded cylinder 6 is inserted and secured in the cover cylinder 8. Thus, the delivering out of the cosmetic stick A is effected in such a manner that the engaging projection 2 of the middle saucer 1 slides through the guide groove 4 of the body cylinder 3 and becomes engaged with the right-hand flight groove 7 of the threaded cylinder 6.

[0019] Two second engaging projections 9' are formed on the outer wall of the lower portion of the cover cylinder 8. A bottomed slide cylinder 10 is inserted and secured in the outer wall of the lower end portion of the body cylinder 3, and a rotation-stopping piece 11 is projected on the outer wall of the slide cylinder 10. A middle cylinder 15' is provided so as to cover the cover cylinder 8 and two left-hand flight grooves 13' with which the engaging projections 9' of the cover cylinder 8 are engaged are formed parallel on the inner circumferential wall of the middle cylinder 15'. Further, a longitudinal engaging groove 14 with which the rotation-stopping piece 11 of the slide cylinder 10 is slidably engaged is formed on the middle cylinder 15'. Furthermore, the middle cylinder 15' is inserted and secured in a bottomed outer cylinder 16 and the top end periphery of the outer cylinder 16 is anchored on an anchoring projection 17 formed on the peripheral wall of the middle cylinder 15'. A plurality of brackets 18 are projected on the middle cylinder 15' so that a topped cylindrical lid (not shown) is dismountably capped.

[0020] In the above-mentioned structure, when the outer cylinder 16 is rotated in the right-hand direction while holding the cover cylinder 8, the left-hand flight grooves 13' formed on the inner wall of the middle cylinder 15' contained and secured in the outer cylinder 16 are concurrently rotated in the right-hand direction. Then, since the engaging projections 9' formed on the cover cylinder 8 are engaged with the left-hand flight grooves 13', the cover cylinder 8 is moved to increase the length exposed from the inside of the middle cylinder 15'. At that time, since the rotation-stopping piece 11 projected on the slide cylinder 10 inserted and secured in the body cylinder 3 is slidably engaged with the engaging groove 14 longitudinally formed on the wall of the middle cylinder 15', the body cylinder 3 is rotated in the right-hand direction with respect to the cover cylinder 8 and the threaded cylinder 6.

[0021] Thus, the middle saucer 1, along with the cosmetic stick A, is longitudinally moved in the body cylinder 3, since the engaging projection 2 formed on the outer wall of the middle saucer 1 contained in the body cylinder 3 and holding the cosmetic stick A thereon pierces through the guide groove 4 and is engaged with the right-hand flight groove 7. After use, if the outer cylinder 16 is rotated in the left-hand direction while holding the cover cylinder 8, the cover cylinder 8 is moved to decrease the length exposed from the middle cylinder 15' and the cosmetic stick A draws back into the body cylinder 3 to complete the contraction for containing the cosmetic stick A.

[0022] A modification of the above-mentioned embodiment of the present invention is shown in Fig. 8. In the modification, a right-hand flight groove 7' with which the engaging projection 2 is engaged is formed on the inner circumferential wall of the threaded cylinder 6 and engaging projection 9' which are engaged with the left-hand flight grooves 13' formed on the inner circumferential wall of the middle cylinder 15' are formed on the outer wall of the lower portion of the threaded cylinder 6. In this case, even if the cover cylinder 8 described above is omitted, a slide type cosmetic stick vessel having the same functions as those of the vessel of the above- mentioned embodiment can be provided.

[0023] In a still further embodiment of the present invention as shown in Figs. 9 and 10, an anchoring portion 20 is provided at the upper end of the body cylinder 1 by projecting a part of the upper end outside. The anchoring portion 20 contacts with the curled upper end of the cover cylinder 8 when the cover cylinder 8 moves down with respect to the body cylinder 1. Thus, the curled upper end of the cover cylinder 8 is prevented from moving down through the upper end of the body cylinder 1, even when an excessive power to force down the cover cylinder 8 is erroneously applied thereto. In this embodiment, a projection 5' is formed at a position near the top end of the body cylinder 3 but below the anchoring portion 20.

[0024] The topped cylindrical lid 19 as shown in Fig. 9 may be provided with an inner lid 21 as illustrated in Figs. 11 and 12. The topped cylindrical lid 19 dismountably capped to be fitted to the upper portion of the middle cylinder 15 or 15' has the inner lid 21 inserted therein. The inner lid 21 is made of a convex metal with an open bottom b, which is provided, on its intermediate, with a shoulder a, and is secured to in the topped cylindrical lid 19 so as to prevent the inner lid 21 from coming out of the topped cylindrical lid 19, so that the open bottom b of the inner lid 21 opens in the same direction as that of the topped cylindrical lid 19. The shoulder a acts to contact with the upper end of the cover cylinder 8 so as to prevent the cover cylinder 8 from coming out. Thus, if the topped cylindrical lid 19 is firmly capped, the cosmetic stick A is prevented from coming out to be damaged by the contact with the lid 19 during carrying.

[0025] The slide type cosmetic stick vessel of the present invention may have a marking on the outer wall of the cover cylinder 8 to make clearly visible the contracted and extended states, as shown in Figs. 13 and 14. The marking may be made by dividing the outer wall surface of the cover cylinder 8 to be exposed from the middle cylinder 15 or 15' in the extended state into two zones 22 and 23 by coloring or drawing a ine. Thus, the zone 23 is exposed from the middle cylinder 15 or 15' in the extended state of the slide type cosmetic stick vessel, while the zone 23 is hidden by the middle cylinder 15 or 15' in the contracted state. If desired, the zones 22 and 23 may have differently colored protective coatings and/or may be indicated as the zone 22 being a zone to be exposed and the zone 23 being a zone to be hidden.
