TECHNICAL FIELD
The present disclosure relates to a cosmetic material feeding-out container, and more particularly to a cosmetic material feeding-out container including an outer tube of cylindrical shape, an inner tube disposed inside the outer tube, and a cosmetic material container disposed inside the inner tube.
BACKGROUND ART
Conventional cosmetic material feeding-out containers, such as the one disclosed in Japanese Unexamined Patent Publication No. H09-347 includes a rotor disposed inside an outer tube rotatable by a rotating cam mechanism, the rotor rotatable by operating the rotating cam mechanism using a knock mechanism, and a cosmetic material holder, rotatable in response to receiving a force of the rotation and linearly moveable along a tube axial direction in response to receiving an effect of a spiral, with which a cosmetic material of stick shape is fed out from the outer tube.
This type of cosmetic material feeding-out containers perform a good operability since the cosmetic material (e.g., lipstick) can be fed out from the outer tube by simply operating the knock mechanism using only one hand.
BACKGROUND ART DOCUMENTS
Summary
However, since component elements, such as a rotatable rod, are assembled between the rotating cam mechanism and the cosmetic material holder in the conventional cosmetic material feeding-out containers of this type, a further improvement in operability, including such as adjustment of feed-out amount and retraction, may be demanded. Further, since the component elements, such as the rotatable rod, are assembled for the conventional cosmetic material feeding-out containers of this type, a further improvement in reliable operability may be demanded. The present disclosure is devised in view of the above background, and is to provide a knock-operable cosmetic material feeding-out container employing a simpler configuration and improved operability, including such as adjustment of feed-out amount and retraction.

EMBODIMENTS
Hereinafter, a description is given of embodiments of the present disclosure with reference to the drawings. FIG. 1 is a side view illustrating an external appearance of a cosmetic material feeding-out container 10 according to a first embodiment of the present disclosure, and FIGS. 2A-2B are is a longitudinal cross-sectional views illustrating one state of the cosmetic material feeding-out container 10. FIG. 2A and FIG. 2B, respectively, illustrate a cross-sectional side view and a cross-sectional front view of the cosmetic material feeding-out container 10. As illustrated in the drawings, the cosmetic material feeding-out container 10 includes an outer tube 1 of a substantially cylindrical shape, an inner tube 2 of substantially cylindrical shape disposed inside the outer tube 1 in a state of protruding a portion of the inner tube 2 from one end of the outer tube 1 (the upper end in the drawing), an intermediate tube 3 of substantially cylindrical shape disposed between the outer tube 1 and the inner tube 2, a cosmetic material container 4 having a bottom and substantially cylindrical shape disposed inside the inner tube 2 with relatively movable along a tube axial direction (the vertical direction in the drawing), and a knocking operation piece 5 protruded from another end of the outer tube 1, that is, the lower end in the drawing. Further, the cross-sectional side view illustrated in FIG. 2A and the cross-sectional front view illustrated in FIG. 2A indicate cross-sectional shapes including the central axis of the outer tube 1, and plane views orthogonal to each other. Further, FIG. 13 illustrates an exploded perspective view of component parts 1 to 9 disposed inside the outer tube 1, and a component part 11 by disassembling the cosmetic material feeding-out container 10.
As illustrated in FIG. 2B, the inner tube 2 includes, for example, two partial extended members 2a provided at an angular pitch of 180 degrees (°) each other and extended downwardly. The extended members 2a are linked with a link portion 1a extended toward the center of the outer tube 1 at the lower portion of the outer tube 1. With this configuration, the inner tube 2 is integrated with the outer tube 1, and thus is prevented from moving relative to the outer tube 1. Further, the inner tube 2 includes, for example, a total of two guide spaces 2b, each formed by cutting away a portion of a tube wall of the inner tube and extended in parallel to a tube axial direction of the inner tube 2 at an angular pitch of 180 degrees with respect to each other. In FIG. 2B, a portion indicated by “2b” is the upper end edge of the guide space 2b.
Further, the cosmetic material container 4, disposed inside the inner tube 2, accommodates a base end portion of the cosmetic material 6 of stick-shape (lower end portion in the drawing), and accommodates and holds the cosmetic material 6 in a state of directing a tip end portion (upper end portion in the drawing) of the cosmetic material 6 into a direction opposite with respect to another end of the outer tube 1, that is, toward the upper end in the drawing. As illustrated in FIG. 2B, the lower portion of the cosmetic material container 4 is provided with two partial extended members 4a. Each of the extended members 4a is provided with an engagement member 4b protruded radially outward, and each of the engagement member 4b is moveable within the guide space 2b of the inner tube 2. With this configuration, whereas the cosmetic material container 4 is moveable linearly along the tube axial direction of the inner tube 2, the cosmetic material container 4 cannot perform a relative rotation about the tube axis of the inner tube 2.
A slide guide 7 is fixed below the cosmetic material container 4 in a state of being sandwiched between the two extended members 4a. A slide member 8 is disposed below the slide guide 7. FIG. 14 is a perspective view illustrating shapes and the detailed positional relationship of the slide guide 7 and the slide member 8 viewed from a substantially lower side of FIG. 13. In FIG. 14, a coil spring 9, to be described later, is omitted. As illustrated in the drawing, the slide guide 7 includes an upper plate 7c, and two longitudinal members 7d extended downwardly from the upper plate 7c. A guide hole 7a is formed by cutting through the central portion of the upper plate 7c and extended through the upper plate 7c along the upper to lower direction. Further, two convex members 7b are provided at an end portion of each of the longitudinal members 7d at the side of the upper plate 7c with interposing the longitudinal member 7d between the two convex members 7b. Further, the slide member 8 includes a base member 8d, and two clamp members 8e integrated with the base member 8d and extended upwardly (toward the slide guide 7). A long convex member 8a protruded upwardly is formed at the central portion of the base member 8d, and the convex member 8a is accommodatable inside the guide hole 7a of the slide guide 7. Further, the two clamp members 8e are spaced apart from each other to slidably clamp the two longitudinal members 7d of the slide guide 7 between the two clamp members 8e. With this configuration, the slide member 8 guided by the guide hole 7a is movable relative to the slide guide 7, that is, relative to the cosmetic material container 4, along the upper to lower direction.
The upper portion of the knocking operation piece 5 is fitted and fixed to the slide member 8. The coil spring 9 is disposed between the slide member 8 and the slide guide 7 in a state of compression. The slide member 8 and the knocking operation piece 5 are biased resiliently downwardly by the coil spring 9. However, as illustrated in FIG. 2A, since convex members 8b, formed outwardly at the upper left and right ends of the slide member 8, contact, from the upper side, a receiving member 3b formed inwardly at the lower portion of the intermediate tube 3, the biased slide member 8 and knocking operation piece 5 are prevented from downwardly coming out from the intermediate tube 3.
The cosmetic material 6 of stick shape is, for example, lipstick, but is not particularly limited thereto. Since the upper end of the cosmetic material 6 may be exposed from the inner tube 2, a cover 11 of cylindrical shape having a bottom, freely removeable and engageable to the outer tube 1, is typically provided.
An inner circumferential face of the intermediate tube 3, made of a member of cylindrical shape, is formed with a helical groove 3R by repeatedly winding a groove along a circumferential direction and a tube axial direction. The above-described engagement member 4b of the cosmetic material container 4 is configured to engage with the helical groove 3R. FIG. 3A and FIG. 3B, respectively, illustrate a perspective view near the lower end portion of the intermediate tube 3 viewed from an outer side, and a partial cut-away view near the lower end portion of the intermediate tube 3 viewed from an inner side. Further, FIG. 3C illustrates a cross sectional perspective view of the inner circumferential face of the outer tube 1 disposed outside the intermediate tube 3 by partially cutting-away the outer tube 1. For example, as illustrated in FIG. 3A and FIG. 3B, four cam convex members 3a of mountain-like shape are formed and arranged at an angular pitch of 90 degrees each other, and protruded downwardly at the lower end portion of the intermediate tube 3. More specifically, the cam convex member 3a includes a straight line portion extended along the axial direction of the intermediate tube 3, and an inclined face extended upwardly from the lower end of the straight line portion. Further, a plurality of cam crest members 3c are formed near the lower end portion of the intermediate tube 3 with protruded toward the center of the intermediate tube 3 with a given uniform thickness, from the inner circumferential face of the intermediate tube 3. These cam crest members 3c are formed, for example, at an angular pitch of 45 degrees, which means a total of eight cam crest members 3c are formed along the entire circumference of the intermediate tube 3.
As illustrated in FIG. 3C, a cam plate 20 having a given uniform thickness is formed on the inner circumferential face of the outer tube 1 with protruded toward the center of the outer tube 1. The cam plate 20 includes a groove portion 20a, cut relatively deeper from the upper end as straight-line portion along the axial direction of the outer tube 1, a first inclined member 20b extended obliquely downward from the upper end at one side edge of the groove portion 20a and relatively longer in the lateral direction, and a second inclined member 20c having a top position on a straight line elevated from the lower-most end of the first inclined member 20b and extended obliquely downward from such position and continued to the other side edge of the groove portion 20a with relatively shorter in the lateral direction. For example, the same one is repeated along the circumferential direction of the tube at an angular pitch of 90 degrees for each of the groove portion 20a, the first inclined member 20b, and the second inclined member 20c to form four groove portions 20a, four first inclined members 20b, and four second inclined members 20c. Further, the lower-most end of the first inclined member 20b, from which the second inclined member 20c is rising, is located at a position sufficiently higher than the bottom face of the groove portion 20a.
FIG. 4 illustrates a schematic front view of near the lower end portion of the intermediate tube 3 and the above-described slide member 8 both viewed from an outer side. FIG. 4 illustrates a state that the intermediate tube 3 and the slide member 8 are not engaged with each other. Further, in FIG. 4, only two of the four cam convex members 3a are illustrated, and other two cam convex members 3a between them are omitted. Further, the cam crest member 3c, illustrated in FIG. 3B, is indicated with broken lines. As illustrated in FIG. 4, the slide member 8 includes a cam convex member 8c facing the cam crest member 3c illustrated in FIG. 3B. For the sake of description to be described later, in FIG. 4, the slide member 8 is particularly indicated with diagonal line, and the cam plate 20 of the outer tube 1, illustrated in FIG. 3C, is indicated with imaginary line.
Hereinafter, a description is given of an interaction of the cosmetic material feeding-out container 10 employing the above-described configuration according to the first embodiment. FIG. 2A and FIG. 2B illustrate a state of accommodating the cosmetic material 6, held in the cosmetic material container 4, inside the inner tube 2 with not protruded upwardly from the inner tube 2. Hereinafter, this state is referred to as the “state when the cosmetic material being accommodated”. On the other hand, the cosmetic material 6 can be in a state of slightly protruded upwardly from the inner tube 2 for providing a use by performing a given operation, to be described later. Hereinafter, this state is referred to as the “state when the cosmetic material being protruded”. FIG. 5A and FIG. 5B, respectively, illustrate a cross-sectional side view and a cross-sectional front view of the cosmetic material feeding-out container 10 during a transition from the “state when the cosmetic material being accommodated” to the “state when the cosmetic material being protruded,” and FIG. 6A and FIG. 6B, respectively, illustrate a cross-sectional side view and a cross-sectional front view of the cosmetic material feeding-out container 10 at the “state when the cosmetic material being protruded”. The cross-sectional views illustrated in FIG. 5A and FIG. 6A are viewed same as the cross-sectional view illustrated in FIG. 2A, and the cross-sectional views illustrated in FIG. 5B and FIG. 6B are viewed same as the cross-sectional view illustrated in FIG. 2B.
Further, FIG. 7 schematically illustrates side views A, C, and E, and cross-sectional side views B, D, and F of the cosmetic material feeding-out container 10, corresponding to each of the states of FIGS. 2, 5, and 6 described above. Further, the cross-sectional views illustrated in B of FIG. 7, D of FIG. 7, and F of FIG. 7 are viewed same as the cross-sectional view illustrated in FIG. 2A. A of FIG. 7 and B of FIG. 7 correspond to the state of FIG. 2A, C of FIG. 7 and D of FIG. 7 correspond to the state of FIG. 5A, and E of FIG. 7 and F of FIG. 7 correspond to the state of FIG. 6A. Further, FIGS. 8 to 11 sequentially illustrate the positional relationship between the intermediate tube 3 and the slide member 8 during the transition from the “state when the cosmetic material being accommodated” to the “state when the cosmetic material being protruded” for the same portion illustrated in FIG. 4. FIGS. 12A-12C illustrate views mainly illustrating a convex member 7b of the above-described slide guide 7, in which FIG. 12A illustrates a side view including a cross section of B-B where the convex member 7b exists, FIG. 12B illustrates a shape view at the cross section of B-B, and FIG. 12C illustrates the view at the cross section of B-B in a state different from FIG. 12B. In FIGS. 12A-12C, the above-described coil spring 9 is omitted.
When the cosmetic material is being accommodated, the cam convex member 3a at the lower portion of the intermediate tube 3, illustrated in FIGS. 3A-3C, is in a state of being inserted into the groove portion 20a of the cam plate 20. Further, the slide member 8 is being at a position away from the intermediate tube 3 downwardly. FIGS. 2 and 8 illustrate this state. If a user of cosmetic material performs a knocking operation (operation of pushing upward) of the knocking operation piece 5 against the elastic force of the coil spring 9 from this state, the cosmetic material container 4 is pushed up via the slide member 8 and the slide guide 7. With this operation, the cosmetic material container 4 slides and moves upwardly inside the inner tube 2. In this operation, the engagement member 4b of the cosmetic material container 4 moves within the guide space 2b of the inner tube 2. Further, the intermediate tube 3, which receives and engages the engagement member 4b in the helical groove 3R, also moves upwardly together with the cosmetic material container 4.
Then, the intermediate tube 3 elevates to a level such that the cam convex member 3a of the intermediate tube 3 comes out from the groove portion 20a of the cam plate 20 upwardly (a state illustrated in FIG. 9). When the intermediate tube 3 has elevated to such level, as illustrated in FIG. 12C, a stopper member 3d protruded from the inner circumferential face at the lower end portion of the intermediate tube 3 abuts against the convex member 7b formed on the slide guide 7 (see FIG. 12C), with which a further elevation of the intermediate tube 3 is stopped. FIGS. 5A-5B illustrates a state when the intermediate tube 3, that is, the cosmetic material 6 has elevated to the highest position by performing the above-described operation. Then, if the knocking operation piece 5 is further pushed upwardly against the elastic force of the coil spring 9, the slide member 8 is elevated accordingly, and the cam convex member 8c formed on the upper portion of the slide member 8 presses the cam crest member 3c of the intermediate tube 3 from the below (a state illustrated in FIG. 10). Then, the cam crest member 3c moves into the right side in FIG. 10 along the cam convex member 8c, with which the intermediate tube 3 rotates into this direction. When the intermediate tube 3 rotates as such, the engagement member 4b, engaged with the helical groove 3R of the intermediate tube 3, moves upwardly, that is, the cosmetic material container 4 moves upwardly. Thus, the cosmetic material 6 held in the cosmetic material container 4 further protrudes upwardly from the inner tube 2.
When a user of cosmetic material feels that the cam crest member 3c has moved along the cam convex member 8c, or confirms that the cosmetic material 6 has protruded from the inner tube 2, the user releases the knocking operation piece 5. Then, the intermediate tube 3 descends such that the cam convex member 3a passes through the second inclined member 20c of the cam plate 20, and is then placed on the first inclined member 20b (more specifically, a state of aligning the straight line portion of the cam convex member 3a with the straight line portion of the second inclined member 20c), and then the intermediate tube 3 comes to rest (a state illustrated in FIG. 11). This state corresponds to the state when the cosmetic material being protruded described above, and the state illustrated in FIGS. 6A-6B. Further, in this case, the portion of the cross-sectional view illustrated in FIG. 12B becomes the state illustrated in FIG. 12C. In this state, since the cosmetic material 6 is protruded from the inner tube 2, the user of cosmetic material can use the cosmetic material 6, such as lipstick, for performing a make-up.
The amount of protrusion (height) of the cosmetic material 6 from the inner tube 2 when the cosmetic material being protruded can be set by totaling one protrusion amount of, for example, 2 mm, when the cam convex member 3a of the intermediate tube 3 rides on the first inclined member 20b of the cam plate 20 and the intermediate tube 3 is elevated to a position higher than a position when the cosmetic material being accommodated, and another protrusion amount of, for example, 0.5 mm, when the cosmetic material container 4 moves upwardly in response to the rotation of the intermediate tube 3, as the total amount of protrusion (height) of 2.5 mm. If the cosmetic material 6 is a lipstick, the protruded amount is preferably an amount that can be used up by performing one-makeup.
In the first embodiment, when the intermediate tube 3 is in the state illustrated in FIGS. 5 and 9, that is, when the cam convex member 3a comes out upwardly from the groove portion 20a of the cam plate 20, a user of cosmetic material can freely rotate the intermediate tube 3. Then, the intermediate tube 3 can be freely rotated in either any one of the directions to move the cosmetic material container 4 along the upper to lower direction, with which the amount of the cosmetic material 6 protruded from the inner tube 2 can be increased, or conversely, the excessively-protruded cosmetic material 6 can be retracted into the inner tube 2.
In the first embodiment, the intermediate tube 3 is rotatable by 45 degrees about the tube axis by performing one knocking operation of the knocking operation piece 5. Therefore, if the one knocking operation is further performed at the state when the cosmetic material being protruded, the intermediate tube 3 is rotated by 45 degrees in the same manner as described above, and then returns to the state when the cosmetic material being accommodated.
As described above, FIG. 7 illustrates the cross-sectional side view of the cosmetic material feeding-out container 10, corresponding to each state of FIGS. 2, 5, and 6 described above. In FIG. 7, in order to compare the height positions of each component part, the upper end position of the inner tube 2 and the lower end position of the outer tube 1, not moved by a knocking operation, are aligned for all of the states as indicated by lines H and L, respectively.
Although the mechanism illustrated in FIGS. 3 and 4 configure the rotating cam mechanism of the present disclosure, this type of rotating cam mechanism has been known to a person skilled in the art. Further, the arrangement angle of the cam elements in the rotating cam mechanism described above and the numbers of cam elements corresponding to the arrangement angle are depicted as merely one example, and it should be noted that these angle and numbers are not limited to those of the first embodiment.
Hereinafter, a description is given of a cosmetic material feeding-out container 30 according to a second embodiment of the present disclosure. FIG. 15 is a side view illustrating an external appearance of the cosmetic material feeding-out container 30 according to the second embodiment. In FIG. 15 and the subsequent drawings, component elements equivalent to those in FIGS. 1 to 14 described above are denoted with the same reference numerals, and the description thereof will be omitted unless otherwise necessary. FIGS. 16A-16B are is cross-sectional views illustrating one state of the cosmetic material feeding-out container 30. FIG. 16A and FIG. 16B, respectively, illustrate a cross-sectional side view and a cross-sectional front view of the cosmetic material feeding-out container 30. Further, FIG. 17 C illustrates an inner circumferential face of the outer tube 1 disposed outside the intermediate tube 3 by partially cutting-away the outer tube 1. As illustrated in FIG. 17 C, a cam plate 20F is formed on the inner circumferential face of the outer tube 1 with protruded toward the center of the outer tube 1 with a given uniform thickness.
The cosmetic material feeding-out container 30 according to the second embodiment is basically different from the cosmetic material feeding-out container 10 of the first embodiment such that the cam plate 20F is different from the cam plate 20 illustrated in FIG. 3 C. That is, as similar to the cam plate 20 illustrated in FIG. 3 C, the cam plate 20F includes eight first inclined members 20b arranged in a state of repeating along the circumferential direction of the tube at an angular pitch of 45 degrees. Further, the mutual positional relationship between the near of lower end portion of the intermediate tube 3 and the slide member 8 in the second embodiment is similar to that illustrated in FIG. 4.
Therefore, in the second embodiment, each time the knocking operation piece 5 is knock-operated, the four cam convex members 3a formed at the lower end portion of the intermediate tube 3 sequentially move onto the next first inclined member 20b, and thus the intermediate tube 3 rotates 45 degrees for each time. If a state when each of the four cam convex members 3a being placed on the first inclined member 20b is referred to as an initial state, the initial state is set for each time the knocking operation of the knocking operation piece 5 is performed. Also in this configuration, if the knocking operation piece 5 is pushed up completely between one initial state and the next initial state, the cam convex member 8c of the slide member 8 pushes up the cam crest member 3c of the intermediate tube 3 to the highest position, and thus the intermediate tube 3 and the cosmetic material container 4 (that is, the cosmetic material 6) can reach the highest position accordingly. When the knocking operation piece 5 is released after this state, the intermediate tube 3 and the cosmetic material container 4 slightly descend from the highest position and become the initial state. In FIG. 18, A of FIG. 18, B of FIG. 18, and C of FIG. 18, respectively, indicate the above-described initial state, the state that the intermediate tube 3 and the cosmetic material container 4 have reached the highest position, and the next initial state. C of FIG. 18— illustrates the state after performing the knocking operation for five times.
As can be understood from the above description, different from the first embodiment, in the second embodiment, the intermediate tube 3 is not configured to directly move relative to the inner tube 2 along the tube axial direction using the rotating cam mechanism. That is, in the second embodiment, the cosmetic material 6 is fed out from the inner tube 2 simply using the rotation of the intermediate tube 3 and the effect of the helical groove 3R. In this configuration, a user of cosmetic material may perform a knocking operation continuously with a greater force, and thus may feed out an excessive amount of the cosmetic material 6. Therefore, the amount of the cosmetic material 6, protrude-able from the inner tube 2 in response to the one knocking operation, may be preferably set relatively smaller.
