Description

Technical Field

[0001] The present invention relates to a cosmetic container for storing cosmetics, and more particularly to a cosmetic container capable of preventing the stored cosmetics from deteriorating due to ultraviolet rays and capable of checking the remaining amount thereof.

Background Art

[0002] Conventionally, various cosmetics such as liquid and cream have been known. However, many of such cosmetics deteriorate when irradiated with ultraviolet rays. Therefore, it has been proposed to form a container for storing cosmetics from a material having an ultraviolet shielding effect. However, if the cosmetic container is formed from a material having an ultraviolet shielding effect, it becomes impossible or difficult to check the remaining amount of the cosmetics inside the container. Therefore, various cosmetic containers have been proposed that are formed from a material having an ultraviolet shielding effect while allowing the remaining amount of the cosmetics inside the container to be visible.

[0003] For example, Patent Document 1 discloses a container formed by mounting a structure having a pair of transparent plates arranged opposite to each other, one of which has a retroreflective structure on the opposing surface, and a mechanism for supplying and discharging a liquid to and from the retroreflective structure. According to this container, normally, the retroreflective structure is set in a light-reflecting state to block the incidence of ultraviolet rays into the container, and a liquid is supplied to the retroreflective structure only when it is desired to check the remaining amount of the contents of the container to make it in a light-transmitting state. After the remaining amount check is completed, the retroreflective structure can be returned to the light-reflecting state.

[0004] Further, Patent Document 2 discloses a cosmetic container in which an opaque inner container to which an airless discharge pump for discharging the contents is coupled is combined with a transparent outer container to form a double container. A disk is disposed inside the inner container, while an insertion groove is formed on the inner surface of the outer container, and a remaining amount display band connected to the disk is inserted into the insertion groove. According to this container, the remaining amount of the contents stored in the inner container can be checked by the height of the remaining amount display band.

[0005] Further, Patent Document 3 discloses a dispenser container in which an inner partition wall portion that is capable of rising and has a flow mechanism through which a liquid content can flow is fitted inside a container body that houses the liquid content. A viewing window is provided in the container body so that the partition wall portion can be seen through the viewing window. According to this dispenser container, the remaining amount of the liquid content can be confirmed by looking at the height position of the partition wall portion through the viewing window.

[0006] Further, Patent Document 4 discloses a container in which a remaining amount viewing window made of a transparent body for determining the remaining amount of the contents is formed on the side wall of an opaque container, and the remaining amount viewing window is covered with a light-shielding member. More specifically, the light-shielding member is a label piece that is removably attached to the outside of the remaining amount viewing window by an adhesive provided on the back surface, or a printed portion formed on a film-like winding body rotatably disposed on the outer peripheral surface of the side wall of the opaque container. According to this container, the remaining amount of the contents can be confirmed through the remaining amount viewing window by peeling off the label piece from the remaining amount viewing window or rotating the winding body to shift the printed portion from the position of the remaining amount viewing window.

[0007] Further, Patent Document 5 discloses a double container in which an outer container and an inner container for storing the contents are assembled so as to be rotatable. A transparent window portion is provided on the outer peripheral surface of the outer container, and a transparent portion and a display portion whose positions are switched according to the rotation angle with the outer container are provided on the outer surface of the inner container. A container is shown in which an opaque sticking sheet that covers the window portion is detachably attached via an adhesive portion to a portion corresponding to the window portion of the outer container. According to this container, the remaining amount and state of the contents can be confirmed by setting the rotation positions of the two containers so that the transparent window portion of the outer container and the transparent portion of the inner container are aligned.

[0008] Further, Patent Document 6 discloses a windowed container including an inner container for storing the contents and an outer container that is rotatable relative to the inner container, and window portions through which the inside can be visually recognized are provided on the outer peripheral walls of the inner container and the outer container. According to this container, the remaining amount and state of the contents can be confirmed by setting the rotation positions of the two containers so that the window portions of the inner container and the outer container are aligned.

Summary of the Invention

Problems to be Solved by the Invention

[0010] The containers shown in Patent Documents 1 and 2 are recognized to have problems of complex structure and high cost. Although the containers shown in Patent Documents 3 to 6 have a relatively simple structure, the following problems are recognized because they are provided with transparent window portions. That is, such window portions are often soiled or scratched with repeated use of the container. In particular, when a sticker sheet is adhered to this window portion, the window portion is often soiled by the adhesive layer. In such a state, it becomes difficult to accurately check the remaining amount of the stored contents.

[0011]

Means for Solving the Problems

[0012] The cosmetic container according to the present invention, as one embodiment, A bottomed container for storing cosmetics, comprising a container body having a transparent portion in at least a predetermined range from the bottom to a position above the bottom, A bottomless cylindrical member made of a light-shielding material, having a side opening formed to make at least the transparent portion of the container body visible from the outside, and surrounding the container body from the side outside, A lid made of a light-shielding material for holding the container body and the cylindrical member, A rotating shutter made of a light-shielding material, assembled to the cylindrical member and non-contact with the container body, The rotating shutter is relatively rotatable in the circumferential direction of the cylindrical member, and thus is rotatable with respect to the container body, the cylindrical member, and the lid, When the rotating shutter rotates relative to the cylindrical member The rotating shutter contacts the edge of the side opening to close the side opening (closed position), A part of the rotating shutter enters the inner diameter side of the cylindrical member and the rotating shutter moves away from the edge to open the side opening (open position), and it can selectively take these positions, which is characterized by this.

[0013] The opening formed in the bottomless cylindrical member is preferably a slit-shaped opening extending in the axial direction of the cylindrical member over a length close to the entire length of the cylindrical member. Further, the cosmetic container according to the present invention further includes a bottom plate made of a light-shielding material for closing the opening on the lower end side of the bottomless cylindrical member, and the bottom plate is relatively rotatable in the circumferential direction of the bottomless cylindrical member, and the rotating shutter is preferably fixed on the bottom plate and rotates together with the bottom plate.

[0014] Further, the cosmetic container according to the present invention preferably further includes a dip tube immersed in the liquid cosmetic stored in the container body, and a spraying device for spraying the liquid cosmetic sucked through the dip tube in a spray shape. Further, in the cosmetic container according to the present invention, it is desirable that the entire container body is transparent and the container body is composed of a cylindrical member.

Effect of the Invention

[0015] The cosmetic container of the present invention comprises a container body having a transparent portion in a predetermined range from at least the bottom to a position above the bottom, a light-shielding cover integrated with the container body in a state of surrounding the container body, and a movable light-shielding member that can selectively assume an open position where a gap is formed between the light-shielding cover by moving relative to the light-shielding cover while being assembled thereto, and a closed position where no gap is formed. Therefore, by simply operating the movable light-shielding member to move to the open position as appropriate, the remaining amount of the cosmetic in the container body can be easily confirmed. That is, according to the cosmetic container of the present invention, the remaining amount of the cosmetic can be confirmed more easily compared to the case of opening the container lid one by one for confirming the remaining amount of the cosmetic. On the other hand, if the light-shielding member is set to the closed position, it is possible to surely prevent the cosmetic in the container body from deteriorating due to ultraviolet rays.

[0016] Further, since the cosmetic container of the present invention is configured to view the container body inside thereof through the gap formed between the movable light-shielding member and the light-shielding cover, it is possible to accurately confirm the remaining amount of the cosmetic stored in the container body without causing the problems recognized in the conventional device, that is, the problem that the transparent window portion for confirming the remaining amount of the cosmetic becomes dirty or scratched.

Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 4. FIG. 1 shows the overall shape of a cosmetic container 1 according to a first embodiment of the present invention, and FIG. 2 shows the cosmetic container 1 partially disassembled and in a partially transparent state. As shown in these figures, the cosmetic container 1 includes, for example, a container body 10 formed in a bottomed cylindrical shape, and a bottomless cylindrical outer cylinder 11 arranged substantially coaxially with the container body 10 so as to cover most of the container body 10 from the side outside, a lid portion 12 disposed on the outer cylinder 11, and a cylindrical convex portion 13 formed at the upper end of the lid portion 12 and having a smaller diameter than the lid portion 12.

[0019] In FIG. 2, the outer cylinder 11 is shown in a transparent state. The outer cylinder 11 and the container body 10 are integrated with the lid portion 12 at the upper portion and held by the lid portion 12. In FIG. 2, the bottom of the container body 10 is shown as 10a. The container body 10 is formed of, for example, a transparent resin or transparent glass over its entire length so that the remaining amount of the cosmetic C can be visually recognized from the outside as will be described later. On the other hand, the outer cylinder 11 is formed using an opaque light-shielding material, more specifically, a member appropriately colored in a preferable color in consideration of the appearance, in order to prevent the cosmetic C from deteriorating due to being irradiated with ultraviolet rays through the transparent container body 10. The lid portion 12 is also formed using a light-shielding material and constitutes a light-shielding cover in the present invention together with the outer cylinder 11.

[0020] Inside the above-mentioned cylindrical convex portion 13, a spray button 15 having a laterally oriented spray port 14 is arranged. The spray port 14 communicates with a suction dip tube 16 arranged inside the container body 10 via a passage inside the spray button 15 and a spray unit (not shown). The above spray unit is a known unit applied to a spray device, also called a spraying device or an aerosol device, etc., and includes a metering chamber and a valve mechanism, etc.

[0021] Due to the action of this spray unit, first, when the spray button 15 is depressed to a certain extent, the connection between the metering chamber and the dip tube 16 is blocked. When the spray button 15 is further depressed, the cosmetic C stored in the metering chamber is sprayed (atomized) from the spray port 14. Then, when the spray button 15 is released, the spray button 15 returns to its original position, which is a high position, by a biasing means (not shown). At this time, the connection between the metering chamber and the dip tube 16 is opened, and the cosmetic C inside the container body 10 is sucked up through the dip tube 16 and stored in the metering chamber in a certain amount.

[0022] Below the outer cylinder 11, a bottomed cylindrical skirt part 20 is arranged. When the skirt part 20 is arranged below the outer cylinder 11 in a state where its upper end (the end opposite to the bottom) is in contact with the outer cylinder 11 as described later, it houses the part of the container body 10 that protrudes below the outer cylinder 11 inside. The skirt part 20 constitutes a moving light-shielding member in the present invention and is formed of an opaque light-shielding material similar to the outer cylinder 11. That is, the skirt part 20 is preferably colored in a dark color as appropriate in consideration of preventing the cosmetic C from deteriorating due to ultraviolet irradiation through the container body 10 and also considering the appearance. As an example, two connecting members 21 are connected to the upper end of the skirt part 20, and a substantially cylindrical screw part 22 is connected to these connecting members 21. The screw part 22 has a screw ridge 22a formed on its outer peripheral surface.

[0023] On the one hand, the above-described cylindrical outer cylinder 11 has a thread groove 11a as a spiral engaging portion formed on its inner peripheral surface. The thread ridge 22a of the screw part 22 is formed as an engaged portion that engages with the thread groove 11a of the outer cylinder 11. Therefore, as shown in FIG. 2, when the skirt part 20 is disposed below the outer cylinder 11 and the thread ridge 22a of the screw part 22 is engaged with the thread groove 11a of the outer cylinder 11 and then the skirt part 20 is rotated, the screw part 22 can be screwed forward and backward in the axial direction of the cylinder within the outer cylinder 11. By thus screwing the screw part 22 forward and backward, the skirt part 20 also moves in the axial direction of the outer cylinder 11 together with the screw part 22. Note that the thread groove 11a and the thread ridge 22a in the present embodiment are formed as two-start threads with a lead that is twice the pitch. Therefore, compared with the case where the thread groove 11a and the thread ridge 22a are ordinary single-start threads, the skirt part 20 can be moved a relatively long distance in the above-described axial direction of the cylinder by rotating the skirt part 20 by a relatively small angle.

[0024] Therefore, by moving the skirt part 20 to the maximum extent toward the outer cylinder 11, as shown in FIG. 1, the upper end surface of the skirt part 20 can be brought into contact with the lower end surface of the outer cylinder 11 so that the two are continuously connected without a gap. Further, by moving the skirt part 20 in a direction away from the outer cylinder 11 from that state, as shown in FIG. 3, the upper end surface of the skirt part 20 can be separated from the lower end surface of the outer cylinder 11 so that a gap is formed between the two. Note that the cosmetic container 1 in this state is shown in FIG. 4 with the outer cylinder 11 in a transmissive state. Here, the thread groove 11a and the thread ridge 22a are usually formed as right-handed threads. In that case, when the skirt part 20 is rotated clockwise, the skirt part 20 moves in a direction approaching the outer cylinder 11, and when the skirt part 20 is rotated counterclockwise, the skirt part 20 moves in a direction away from the outer cylinder 11.

[0025] When the use of the cosmetic C is repeated, its remaining amount gradually decreases, and the liquid level L of the cosmetic C drops to a position close to the bottom 10a of the container body 10. FIGS. 3 and 4 show a state where the liquid level L is at such a position. On the other hand, as described above, a part of the container body 10 including the bottom 10a is formed so as to protrude downward from the outer cylinder 11. That is, the overall length of the container body 10 is made larger than the overall length of the outer cylinder 11. Therefore, as shown in FIGS. 3 and 4, if the skirt part 20 is lowered to a position (open position) where a gap is generated between the outer cylinder 11, the part close to the bottom 10a of the container body 10 can be seen. Thereby, the user can confirm whether the liquid level L of the cosmetic C has dropped to a position close to the bottom 10a of the container body 10 and the remaining amount of the cosmetic C is small. And in the cosmetic container 1 of the present embodiment, since the container body 10 is viewed through the above-mentioned gap, the problem that the transparent window portion provided for confirming the remaining amount of the cosmetic is soiled or scratched is not caused, and the remaining amount of the cosmetic C can be accurately confirmed. This point is the same also in the cosmetic container 2 according to the second embodiment described below.

[0026] The confirmation of the remaining amount of the cosmetic C made as described above may be appropriately performed by the user based on his / her memory regarding the use of the cosmetic. In normal times other than when this remaining amount is confirmed, that is, when using or carrying the cosmetic container 1, the skirt part 20 is set to the position (closed position) in FIG. 1 where no gap is generated between the outer cylinder 11. If the cosmetic container 1 is in this state, the transparent container body 10 storing the cosmetic C is covered by the opaque outer cylinder 11 and the skirt part 20 on the outer periphery, and the outside of the bottom 10a is also covered by the skirt part 20. Also, the upper part of the container body 10 is originally covered by the lid part 12. Therefore, it is possible to prevent the cosmetic C in the container body 10 from deteriorating by receiving ultraviolet rays from the outside. Since the screw groove 11a and the screw protrusion 22a are two-threaded screws as described above, the operation of moving the skirt part 20 between the above-mentioned closed position and the open position can be performed quickly.

[0027] In addition to forming the entire container body 10 transparently, only a predetermined range (i.e., a predetermined range above the bottom 10a) that can be visually recognized when the skirt part 20 is set to the above-mentioned open position is formed of a transparent material, and the remaining part may be formed of a light-shielding material to more reliably prevent ultraviolet rays from entering the stored cosmetic C.

[0028] Also, it is desirable to prevent the skirt part 20 from inadvertently moving to the open position side from the above-mentioned closed position. For this purpose, for example, the screw protrusion 22a and the screw groove 11a may be configured so that an appropriate frictional resistance is generated between them when the skirt part 20 rotates, and the screw protrusion 22a is prevented from easily advancing and retreating with a small force. In addition to being a double-threaded screw, the screw groove 11a and the screw protrusion 22a may be a multi-threaded screw such as a triple-threaded screw or a quadruple-threaded screw. Since it is not necessary to maintain a particularly high airtightness between the outer cylinder 11 and the skirt part 20, it is desirable to apply such a multi-threaded screw while emphasizing the speed of operation. However, such a multi-threaded screw may not be applied, and the screw groove 11a and the screw protrusion 22a may be a normal single-threaded screw.

[0029] Also, the inner peripheral surface of the outer cylinder 11 on which the screw groove 11a is engraved needs to be the inner peripheral surface of a cylinder, but the outer peripheral surface of the outer cylinder 11 does not have to be the outer peripheral surface of a cylinder. For example, this outer peripheral surface may be the outer peripheral surface of a polygonal cylinder such as a square cylinder. On the other hand, the peripheral wall part of the skirt part 20 may have an inner peripheral surface and / or an outer peripheral surface formed of a surface other than a cylindrical surface. However, considering the aesthetics of the cosmetic container 1, it is desirable that the outer peripheral surface of this peripheral wall part has a shape that coincides with the outer peripheral surface of the outer cylinder 11 when the skirt part 20 is set to the above-mentioned closed position.

[0030] Also, in the present embodiment, a structure in which a screw ridge 22a is screwed into a screw groove 11a is applied to move the skirt part 20 between a closed position and an open position. However, the skirt part 20 may be made movable by other structures. Examples of such structures include applying a normal cylindrical member without a screw ridge 22a instead of the generally cylindrical screw part 22. When this cylindrical member receives an operating force, it is configured to be movable in the cylinder axis direction along the inner peripheral surface of the outer cylinder 11 while generating an appropriate frictional resistance. When applying such a configuration, in order to prevent the cylindrical member replacing the screw part 22 from falling off downward from the outer cylinder 11, for example, means for attracting them by magnetic force can be used.

[0031] Note that the cosmetic container of the present invention does not include the dip tube 16 described above and a spray device for spraying the liquid cosmetic sucked through this dip tube 16 in a spray form. For example, it may be formed such that a small cap provided partially on the lid part 12 is opened and the cosmetic is taken out from the upper opening of the container body 10 for use. However, a cosmetic container configured in such a manner generally needs to be tilted frequently when taking out the cosmetic, and it is easy for the user to recognize the remaining amount of the cosmetic from the required degree of tilt at that time. On the other hand, a cosmetic container provided with the above dip tube 16 and spray device is difficult for the user to recognize the remaining amount of the cosmetic until the cosmetic stops being sprayed in a spray form or the spraying amount decreases. Therefore, applying the present invention to that type of cosmetic container is particularly preferable because it has a high effect of preventing the sudden situation of running out of the cosmetic and being unable to use it.

[0032] Next, referring to FIGS. 5 to 9, the cosmetic container 2 according to another embodiment of the present invention will be described. In FIGS. 5 to 9, elements equivalent to those in FIGS. 1 to 4 described above are denoted by the same reference numerals, and descriptions thereof will be omitted unless particularly necessary. FIGS. 5 and 6 show the overall shape of the cosmetic container 2 according to the second embodiment of the present invention. In particular, FIG. 6 shows the outer cylinder 30 constituting the cosmetic container 2 in a transparent state. The outer cylinder 30 is formed in a substantially bottomless cylindrical shape using a light-shielding material, similarly to the outer cylinder 11 described above. However, this outer cylinder 30 has a slit-shaped opening (side opening) 30a that extends in the axial direction of the cylinder from a position slightly below the upper end to the lower end, different from the outer cylinder 11. The outer cylinder 30 and the container body 10 are integrated with and held by a lid portion 12 made of a light-shielding material at the upper part. The end opening on one end side (the upper end side in the figure) of the outer cylinder 30 is closed by this lid portion 12.

[0033] A disk-shaped bottom plate 40 made of a light-shielding material is arranged on the other end side (the lower end side in the figure) of the outer cylinder 30 as will be described later. The container body 10 is surrounded by the bottom plate 40, the lid portion 12, and the portions of the outer cylinder 30 other than the opening 30a. That is, the bottom plate 40, the lid portion 12, and the portions of the outer cylinder 30 other than the opening 30a constitute a light-shielding cover in the present invention that blocks the entry of external light into the container body 10.

[0034] On the above bottom plate 40, a rotary shutter 43 composed of a thick portion 41 and a thin portion 42 that both extend in the longitudinal direction of the outer cylinder 30 is erected. This rotary shutter 43 is also formed of a light-shielding material and is combined with the outer cylinder 30. Here, FIGS. 7 and 8 show an enlarged view of the peripheral portions of the outer cylinder 30 and the rotary shutter 43. FIG. 7 is a cross-sectional plan view showing a position near the middle within the entire length of the outer cylinder 30 cut in a plane perpendicular to the axial direction of the outer cylinder 30. On the other hand, FIG. 8 is a side cross-sectional view showing the portion along the Y line shown in FIG. 7 as viewed from the direction of the arrow in FIG. 7 across the entire width of the outer cylinder 30. In FIG. 8, the disk-shaped bottom plate 40 and the similarly disk-shaped holding members 44, 45, 46 are shown in a state as viewed from the side without showing the cross-section.

[0035] As shown in FIG. 8, between the disk-shaped holding members 44 and 45, a holding member 46 having an outer diameter smaller than theirs is arranged, and these holding members 44, 45, and 46 are fixed on the bottom plate 40. In FIGS. 7 and 8, the rotary shutter 43 erected on the bottom plate 40 (the thick portion 41 through which the cross section passes in FIG. 8) is shown in a state separated from the holding members 44 and 45 for easy understanding. However, actually, the inner surface of the rotary shutter 43 is a curved surface along the outer peripheral surfaces of the holding members 44 and 45, and the inner surface is slidable with the holding members 44 and 45 and is arranged in a state of contacting the outer peripheral surfaces of these holding members 44 and 45.

[0036] Also, the bottom plate 40 is arranged so as to be slightly separated from the lower end surface of the outer cylinder 30 and is relatively rotatable with respect to the outer cylinder 30. For this purpose, on the inner peripheral surface of the outer cylinder 30, an annular convex portion 31 is formed which projects inward of the cylinder in a substantially annular shape in a portion excluding the rotation range of the rotary shutter 43 that rotates as described later. This annular convex portion 31 is loosely fitted between the holding members 44 and 45, defines the vertical position of the bottom plate 40 with respect to the outer cylinder 30 as described above, and enables the bottom plate 40 to rotate relative to the outer cylinder 30. When the bottom plate 40 rotates in this way, the holding members 44, 45, 46 and the rotary shutter 43 integrated with the bottom plate 40 also rotate together with the bottom plate 40.

[0037] FIG. 7 shows the combined state of the rotary shutter 43 and the outer cylinder 30. As shown here, the flat cross-sectional shape of the outer cylinder 30 is made to correspond to the flat cross-sectional shape of the rotary shutter 43 consisting of the thick portion 41 and the thin portion 42, allowing the rotary shutter 43 to rotate together with the bottom plate 40. The rotary shutter 43 constitutes the moving light-shielding member in the present invention, and by rotating, it can selectively take a closed position where it closes the opening 30a of the outer cylinder 30 and an open position where it opens a part of the opening 30a. That is, as shown in FIG. 7, among the edges extending in the vertical direction (the direction perpendicular to the paper surface of FIG. 7) of the opening 30a, the portion of the outer cylinder 30 adjacent to the edge on the thin portion 42 side is a thin portion having an inner peripheral surface 30b that allows the outer peripheral surface of the thin portion 42 to slide. Also, among the edges extending in the vertical direction of the opening 30a, the portion of the outer cylinder 30 adjacent to the edge on the thick portion 41 side is also shaped to receive the short convex portion protruding leftward in the figure from the thick portion 41.

[0038] FIG. 7 shows the state where the rotary shutter 43 is in the above-described closed position. However, due to the portion of the outer cylinder 30 adjacent to the edge of the opening 30a being shaped as described above, when the rotary shutter 43 is set in this closed position, external light is prevented from entering the inside of the outer cylinder 30 through the opening 30a. When the rotary shutter 43 is rotated counterclockwise in the figure from the state of FIG. 7, the rotary shutter 43 rotates such that its thin portion 42 slides on the inner peripheral surface of the thin portion of the outer cylinder 30, and the thick portion 41 moves away from the edge of the opening 30a. Thus, when the thick portion 41 moves away from the edge of the opening 30a and opens the opening 30a even partially, the position of the rotary shutter 43 is the open position.

[0039] When the rotary shutter 43 rotates and moves to the position where the opening 30a is fully opened, the side end of the thick portion 41 of the rotary shutter 43 abuts against the side end of the outer cylinder 30 that forms the edge of the opening 30a, preventing further rotation of the rotary shutter 43 (the state shown in Fig. 9). The rotation operation of the rotary shutter 43 can be performed by directly moving, for example, the thick portion 41 of the rotary shutter 43, or by rotating the bottom plate 40. The rotary shutter 43 is basically formed concentrically with the outer cylinder 30 and rotates concentrically. This concentric rotation is achieved by a mechanism that combines the annular convex portion 31 and the outer cylinder 30 with the holding members 44, 45, 46 integrated with the rotary shutter 43.

[0040] Figs. 5 and 6 show the cosmetic container 2 when the rotary shutter 43 is in the closed position. If the rotary shutter 43 is in the closed position and blocks external light, the cosmetic C in the container body 10 is prevented from deteriorating due to ultraviolet rays from the outside. On the other hand, Fig. 9 shows the cosmetic container 2 when the rotary shutter 43 is in the open position. In this case, the user can see almost the entire length of the container body 10 inside the outer cylinder 30 through the partially opened opening 30a. Thereby, the user can appropriately confirm whether the remaining amount of the cosmetic C is small.

[0041] In addition to forming the entire container body 10 transparent, only a predetermined range that can be visually recognized when the rotary shutter 43 is set to the aforementioned open position may be formed of a transparent material, and the remaining portion may be formed of a light-shielding material to more reliably prevent ultraviolet rays from entering the stored cosmetic C. The aforementioned "predetermined range" may be, for example, a slit-shaped portion with a predetermined width extending over the entire length of the container body 10 facing the opening 30a side of the outer cylinder 30, or even more specifically, only a predetermined length portion from the bottom 10a upward that is necessary for confirming the remaining amount of the cosmetic C among such slit-shaped portions.

[0042] Also, it is desirable to prevent the rotary shutter 43 from inadvertently moving to the open position side from the above-described closed position. To this end, during the rotation of the rotary shutter 43, for example, an appropriate frictional resistance acts between the surfaces on the holding member 46 side of the holding members 44 and 45 shown in FIG. 8 and the annular convex portion 31, or between the outer peripheral surfaces of the holding members 44 and 45 and the outer cylinder 30, so that the rotary shutter 43 does not rotate easily with a small force. Further, a plurality of slit-shaped openings 30a as side openings in the outer cylinder 30 may be provided apart from each other in the circumferential direction of the outer cylinder 30. Thereby, when the opening 30a is opened, the inside of the outer cylinder 30 becomes brighter, so that the remaining amount of the cosmetic C can be confirmed more reliably and easily. In that case, the plurality of openings 30a may be opened and closed in conjunction with different portions of one rotary shutter, or may be independently opened and closed by individual rotary shutters.

[0043] Also, as described above, examples of the liquid cosmetic C used in a spray form include perfumes, lotions, antiperspirants, etc., but are not limited thereto. Further, the cosmetic container of the present invention is not limited to the cosmetic C as described above, and can store various cosmetics such as liquid cosmetics that are not in a spray form, cream cosmetics, and solid cosmetics, and further can store chemicals that may be deteriorated by ultraviolet rays.
