Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a stick-shaped cosmetic delivery container.
[0002]
[Prior art]
As a stick-shaped cosmetic delivery container represented by lipsticks and ticks, a combination of a spiral cylinder, a middle cylinder with a vertical slit, an outer cylinder, and a casing is known. There is a problem that it is complicated because it is necessary to pick and rotate the casing with the other hand, and the number of parts is large and the assembly is troublesome.
Therefore, Japanese Utility Model Laid-Open No. 58-112214, Japanese Utility Model Laid-Open No. 1-82819 and Japanese Utility Model Laid-Open No. 1-104912 are provided with a two-part main body having an opening at the upper end and a tray holding cosmetics at one end. This type of container has been proposed in which a belt provided with a shutter portion at the other end is arranged in a U shape, and the opening and closing of the shutter portion is opened and closed by sliding the belt to make cosmetics appear and disappear. .
According to these prior arts, a stick-shaped cosmetic can be made to appear and disappear by moving a button with the fingertip of the hand while holding the container with one hand, and there is an advantage in that parts such as caps can be omitted.
[0003]
However, in these prior arts, when the belt is slid by the operation piece protruding from the vertical hole of the container body, the belt bends in a wave shape in the thickness direction due to sliding resistance when the shutter part is bent toward the opening. There is a problem in that it is easy to deform, and the portion is in close contact with the inner surface of the container, so that a shuri is generated, and the cosmetic cannot be smoothly fed out.
Furthermore, in the prior art, since the belt guide surface has a straight section perpendicular to the axis, the section perpendicular to the axis of the container body has a mechanical characteristic shape with at least one flat surface. For this reason, there is a problem that the appearance is lacking in smartness and elegance as compared with a general-purpose rotary feeding container.
[0004]
As a countermeasure, the present inventor disclosed in Japanese Patent Laid-Open No. 8-126525, a split main body, a flexible belt having a saucer and an operation button, an inner diameter in which the saucer is fitted, and an outer shape closely contacting the inner surface of the main body. In cooperation with the inner surface of the main body so that the cross section perpendicular to the longitudinal direction of the flexible belt is curved on the surface facing the vertical hole of the main body and the surface displaced by 180 degrees. We proposed an assembly of Nakatsuto, each with a longitudinal groove with circumferential curvature to be shaped.
According to this prior art, cosmetics can be smoothly fed out with a light operating force, but the number of parts increases because of the use of the inner cylinder, and the inner dish moves up and down in the inner cylinder. Therefore, there is a problem in that the diameter of the container is increased, and the 180 ° symmetrical position is flat or close to the shape in order to prevent rotation of the middle cylinder.
[0005]
[Problems to be solved by the invention]
The present invention was devised in order to solve the above-mentioned problems, and the object of the present invention is to allow the cosmetics to be smoothly fed out with a light operation force, and the number of parts is extremely small. In addition, an object is to provide a smart stick-shaped cosmetic delivery container having a perfect circular cross section and a small diameter.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a main body comprising a pair of split parts in a bar-shaped cosmetic feeding container of a type in which a belt is slid by movement of an operation button to open and close an opening and bar-shaped cosmetic appears and disappears. A flexible belt having a cylindrical receiving tray to which a shutter section having a cross-sectional shape curved in the width direction for opening and closing the opening is provided at one end, an operation button is integrally provided in the vicinity thereof, and a stick-shaped cosmetic is attached to the other end. The pair of split parts is provided with a semi-opening for cosmetics appearance at the upper end, and a notch for projecting the operation button along the mating surface on the side surface. A semicircular arc-shaped curvature guide groove for U-turning the flexible belt around the axis is provided at the inner lower part of each of the two split parts, respectively, while a pair of two splits above the curvature guide groove. Inside the body, In order to guide the sliding of the flexible belt, a belt guide groove connected to one side opening of the curvature guide groove is provided at a position closest to the groove-shaped notch, and the belt guide groove is arranged in the inner circumferential direction from the belt guide groove. Each having a curvature that substantially matches the curvature of the shutter portion, and a wide curvature groove for the shutter portion guide that has a width that substantially matches the width of the shutter portion in the combined state of the two split portions, The end of the wide curvature groove has a stepped surface to form a thick portion in the circumferential direction, and the lower end of the curvature guide groove is 180 degrees symmetrical to the belt guide groove that is the end of the thick portion. of forms a belt guide groove connected with the other side opening, the thick portion has its inner surface substantially coincides with the plane formed of the outer diameter of the cylindrical pan, and allowed to coalesce the two split portions body peripheral total circumferential length in a state of cylindrical pan It is configured to have an arcuate curvature surface of the receiving portion guides of over 50%.
The cylindrical saucer may be formed integrally with the flexible belt, or may be formed separately and fixed to the flexible belt.
[0007]
[Action]
In the present invention, since the curvature guide groove of the main body is formed in a semicircular arc shape centering on the axis, the flexible belt is U-turned with a large curvature radius, and the shutter portion is curved in the width direction. Because this slides along the wide curvature groove surface formed in the main body, an appropriate guide action is obtained, and even if the flexible belt is thin and soft, the stick-shaped cosmetic product can be fed smoothly and lightly. It can be carried out. Moreover, as a member, only a split part body and a flexible belt, or at most, a small number of parts that only add a saucer to it are sufficient, and even when assembled, the thick part of one of the split parts is a saucer. It is simple and the cost is low because it is only necessary to fit the other two split parts with the flexible belt fitted in the curvature guide groove and the shutter part positioned on the wide curvature surface. Can do.
In addition, a guide member that requires circumferential positioning, such as a middle cylinder, is not built in, but the cross-sectional shutter portion curved in the width direction is directly guided by the wide curvature groove surface formed on the inner surface of the main body. Therefore, the cross-sectional shape of the main body can be a perfect circle, and the cosmetic container can be a smart and elegant cosmetic product with a thin outer diameter.
[0008]

The flat surface 4a is provided with a hole 41 at a portion facing the projection 40, and the split body 1a, 1a is united by fitting the projection 40 and the hole 41 to constitute the main body 1. It is like that.
[0010]
The flexible belt 6 is slidably assembled to the main body 1 in order to open and close the opening 2 and to move the stick-shaped cosmetic A in and out. As shown in FIG. 4, the opening 2 of the main body 1 is closed at one end. A shutter portion 60 of a size that can be obtained is integrally formed, and a cylindrical tray 6 a is integrally formed at the other end via a connecting portion 61. An operation button 62 for sliding operation is integrally formed in the vicinity of the shutter portion 60. The shutter part 60 has a cross-sectional shape that is larger than the width of the belt and curved inward in the width direction as shown in FIG. And the boundary part with a belt can be moderately inclined now as a hinge.
The width of the curvature guide groove formed by the semicircular arc-shaped curvature guide grooves 4b, 4b is appropriately larger than the width of the flexible belt 6, and the depth is also appropriately larger than the thickness of the flexible belt. ing.
[0011]
A belt guide groove 8 for guiding the sliding of the flexible belt 6 is provided in the vicinity of the groove-shaped notch 3a on the inner side of the two split body 1a, 1a. The groove 8 extends in the axial direction and is connected to one side opening of the curvature guide groove 4b. The belt guide grooves 8 and 8 of the split part bodies 1a and 1a are appropriately larger than the width of the flexible belt in the combined state.
Further, a wide curvature groove 8a for guiding the shutter portion 60 is formed in the inner circumferential direction from the belt guide groove 8, and a step surface 81 is provided at the end of the wide curvature groove 8a. A thick portion 8b is formed in the circumferential direction, and a belt guide groove 8 'is formed at the end of the thick portion 8b, that is, at a position symmetrical to the belt guide groove 8 by 180 degrees.
[0012]
The wide curvature grooves 8a, 8a have a curvature that substantially matches the curvature of the shutter portion 60, and in the combined state of the two split portions 1a, 1a, the width is substantially the same as the width of the shutter portion 60 as a whole. The lateral displacement of the shutter portion 60 is prevented by the step surfaces 81, 81 at the boundary with the thick portion 8b.
As shown in FIG. 5 (c), the thick portion 8b has an arcuate curvature surface 82 centered on the center C of the mating surface, and the diameter of the arcuate curvature surface 82 substantially coincides with the outer diameter of the tray 6a. In addition, the total area of the arc-shaped curvature surfaces 82 and 82 in a state where the two split parts 1a and 1a are combined is over 50% of the circumference of the tray 6a.
The thick portion 8b has a base end at the bottom portion 4 in the axial direction and extends from this position in a state of equal thickness and equal width in the axial direction. However, the thick portion 8b is inclined slightly from the front end of the groove-shaped notch 3a. Is reduced and ends at a position substantially matching the lower side of the locking groove 9.
Accordingly, as shown in FIG. 5B, the wide curvature groove 8a extends with the same width along the axial direction from the start end, and gradually expands slightly before the end of the groove-shaped notch 3a to form the end portion 8a ′. Thus, the shutter portion 60 is smoothly tilted forward and guided to the groove-shaped notch 3a.
[0013]
The belt guide grooves 8 ′ and 8 ′ are appropriately larger than the width of the flexible belt in the combined state of the split parts 1 a and 1 a, and the lower end side is the other of the semicircular arc-shaped curvature guide groove 4 b. It is connected to the side opening. As shown in FIG. 1, the upper end ends appropriately below the locking groove 9, that is, at a position corresponding to the maximum projecting position of the tray 6a.
The tray 6a has a cylindrical shape, and a groove-shaped notch 3a and a pin-shaped connecting portion 61 projecting radially from the outer peripheral surface at a 180-degree symmetrical position are connected to the end of the flexible belt 6. ing. In order to guide the parallel movement of the connecting portion 61 in the axial direction, a projection 83 is provided at the end of the thick portion 8b constituting the belt guide groove 8 ′ as shown in FIGS. Thus, in the combined state of the two split parts 1a, 1a, the belt guide grooves 8 ', 8' are formed with slits 84 inward as shown in FIG.
The tray 6a has an arcuate stopper projection 64 at a circumferential position corresponding to the groove-shaped notch 3a side and in the range of the lower half portion in the axial direction. However, as shown in FIG. 1 (b), the upper limit of the tray 6a is restricted by contacting the upper end corner 7 adjacent to the opening 2 of the main body 1.
[0014]
The operation button 62 has a shaft portion 620 that penetrates the vertical hole 3 of the main body 1, and the lower end of the shaft portion 620 is integrally connected to the flexible belt 6.
In this embodiment, the belt width is widened only in the region where the operation button 62 is formed so that the stable operation can be performed without wobbling the operation button 62, and the wide belt portion 6 ′ has a shaft portion 620. Window holes 621 and 621 penetrating in the thickness direction are provided at portions corresponding to both sides of the base end. The window holes 621 and 621 are for removing the belt operation button 62 easily, and are not particularly necessary. Thus, since the portion corresponding to the operation button 62 is the wide belt portion 6 ', the width of the belt guide grooves 8, 8 is wide so as to correspond to this width. However, the belt region in which the operation buttons 62 are formed does not necessarily need to be wide.
[0015]
The flexible belt 6 may have a flat cross section perpendicular to the longitudinal direction as shown in FIG. 7B, but preferably has a curved shape in the molded state as shown in FIG. 7A. By doing so, an angle effect is produced, and the strength of the flexible belt 6 is substantially increased as compared with the conventional case of sliding in a straight line in the width direction, so that the flexible belt 6 is thin and flexible. Even if it is, it will be strong enough in use. It is also recommended that the bottom surface of the belt guide grooves 8, 8, 8 ′, 8 ′ be curved so as to correspond to this cross-sectional shape. In some cases, the tray 6a may be formed separately from the flexible belt 6 and may be integrated by mechanical connection. In this case, if the horizontal hole 65 is formed in the tray 6a as shown in FIG. 8, the connecting pin portion 66 is formed in the flexible belt 6, and the connecting pin portion 66 is inserted into the horizontal hole 65. Good.
[0016]
In any of the embodiments, a metallic gloss surface may be formed on the outer periphery of the main body 1 by means of vapor deposition, transfer adhesion, press fitting, or the like, if necessary.
The bar-shaped cosmetic product A may be directly fitted to the receiving tray 6a. When the capsule-type bar-shaped cosmetic product A is used, the receiving tray 6a is divided into two bodies, and a locking annular protrusion is formed on the inner wall of the first receiving tray. An annular groove is provided on the outer periphery of the second saucer (inner saucer), the bar-shaped cosmetic product A is pushed out of the capsule and held in the second saucer, and the second saucer is fitted to the first saucer in this state. What is necessary is just to make it combine.
Further, in this embodiment, the projection 40 and the recess 41 are used as the uniting mechanism of the split part bodies 1a and 1a. However, the present invention is not limited to this. Alternatively, a tongue-like projection may be provided, and a corresponding fitting groove may be provided along the edge of the mating surface of the other split part 1a.
[0017]
[Effect of the embodiment]
Next, the usage and operation of what is shown in the examples will be described.
In obtaining the bar-shaped cosmetic supply container according to the present invention, the disassembled state as shown in FIG. 4 is adopted. For example, the receiving tray 6a is brought into contact with the thick portion 8b of the left split body 1a, and the flexible portion ahead of the receiving tray 6a. As shown in the figure, the belt 6 is bent into a U-shape and fitted into the semicircular arc-shaped curvature guide groove 4b so that the shaft portion 620 of the operation button 62 faces the groove-shaped notch 3a, and the shutter portion 60 Is brought into contact with the wide curvature groove 8a. In this state, the right split part 1a may be aligned with the left split part 1a so that the split parts 1a and 1a are combined, and the receiving tray 6a is flexible. This is a finished product in which the sexual belt 6 is incorporated. Therefore, the assembly is very simple.
At the time of incorporation, the curvature guide groove 4b is formed in a semicircular arc shape centering on the axis of the main body, and the curvature radius of the U return portion is large. Therefore, the flexible belt 6 cannot be forcibly bent, and the springback hardly occurs in combination with the flexible belt 6 being thin and flexible.
[0018]
FIG. 1A shows a state in which the bar-shaped cosmetic product A is stored. The operation button 62 is positioned at the upper end of the vertical hole 3, and the shutter portion 60 of the flexible belt 6 closes the opening 2. The saucer 6a is in a position past the curvature guide groove 4b.
In use, the operation button 62 is slid downward along the vertical hole 3 as in the conventional case. Since the operation button 62 is integrated with the flexible belt 6, the flexible belt 6 is the main body. The shutter 60 that has moved in the clockwise direction 1 and closed the opening 2 thereby descends in a straight line from the inclined state, while the tray 6a positioned at the end of the curvature guide groove 4b is connected. Since it is integrated with the flexible belt 6 by the portion 61, it moves upward, and the bar-shaped cosmetic A is fed out from the opening 2 as shown in FIG. After application using the stick-shaped cosmetic A in this state, if the operation button 62 located below the vertical hole 3 is slid upward, the flexible belt 6 is counterclockwise along the curvature guide groove 4b. Move in the direction. Thereby, the shutter portion 60 is bent at the upper end corner portion 7 adjacent to the opening 2, moves across the opening 2, and the tip is inserted into the locking groove 9, while the tray 6 a is pulled down and the operation button 62 is operated. Is positioned at the upper end of the vertical hole 3, the bar-shaped cosmetic product A is again immersed in the main body 1 as shown in FIG.
[0019]
In the present invention, the shutter portion 60 is curved in the width direction, and this curved shape is accommodated in the wide curvature grooves 8a and 8a formed on the inner surface of the main body 1, and the upward or downward direction is maintained in such a curved state. Since it slides, it can be slid stably by the angle effect. The flexible belt 6 behind the shutter portion 60 is housed in the curvature guide groove 4b and the belt guide grooves 8, 8, 8 ′, 8 ′ and is moved, so that the flexible belt 6 is stable. Since the strength is increased by the angle effect when the material is bent at the time of molding, the waist becomes sufficiently strong even if it is thin and flexible and can move smoothly. Further, since the shutter portion 60 is curved in the width direction, the contact area with the lower surface of the opening 2 is small (sliding resistance is small), and the connecting portion 61 integrated with the tray 6a is between the belt guide grooves 8 ′ and 8 ′. Are smoothly guided by the slits 84.
Therefore, the flexible belt 6 and the bar-shaped cosmetic A can be smoothly moved by a simple operation force, and the opening and closing of the opening can be smoothly performed for a long time by the shutter unit 60.
[0020]
【The invention's effect】
According to the first aspect of the present invention described above, the semicircular arc-shaped curvature guide groove 4b centering on the axis line is provided at the inner lower portion of the split body 1a, 1a constituting the main body 1, which is possible. The return curvature radius of the flexible belt 6 can be increased, and the sliding resistance at this portion can be reduced. Furthermore, the shutter part 60 has a cross-sectional shape curved in the width direction, and the split part bodies 1a and 1a are formed with wide curvature grooves 8a and 8a for shutter part guides inside the belt guide grooves 8 and 8, respectively. Therefore, the waist of the flexible belt 6 is strengthened by the wide curvature grooves 8a, 8a and the curved shutter portion 60, and is not bent or broken during sliding. Further, the lateral displacement of the shutter portion 60 is prevented by the step surfaces 81 and 81 at the boundary with the thick portion 8b. Therefore, the stick-shaped cosmetic product can be fed out smoothly.
Moreover, a thick wall portion 8b having an arcuate curvature surface 82 that substantially matches the outer diameter of the cylindrical tray 6a is formed in the circumferential direction from the ends of the wide curvature grooves 8a, 8a, and the cylindrical tray 6a can be moved up and down directly only by the main body. Since the parts are guided, the number of parts such as the two split parts 1a, 1a and the flexible belt 6 is sufficient, and even when assembled, the cylindrical saucer is thick in one split part 1a. Since it is only necessary to place the flexible belt 6 in the curvature guide groove 4 and place a U-turn on the portion 8b and to make the other two split portions 1a together, it is very simple and inexpensive.
Further, the shutter portion 60 having a cross-sectional shape curved in the width direction is directly guided by the wide curvature groove surfaces 8a and 8a formed on the inner surfaces of the two split portions 1a and 1a, and the thick portion 8b has an inner surface substantially coincident with a surface formed by the outer diameter of the cylindrical tray 6a, and the total circumferential length in a state where the two split portions 1a and 1a are combined is the circumferential length of the cylindrical tray 6a. By having an arcuate curvature surface 82 for the saucer guide exceeding 50% and guiding the elevation of the saucer 6a directly, the cross-sectional shape of the main body 1 can be made into a thin perfect circle and the outer diameter is narrow. The excellent effect that it can be made into a smart and elegant cosmetic container is obtained.
[0021]
According to the second aspect, since the tray 6a is integrally formed with the flexible belt 6, the excellent effect that the number of parts can be reduced to three is obtained.
According to the third aspect, since the cross section perpendicular to the longitudinal direction of the flexible belt 6 is curved, the waist is strong due to the angle effect, and even the thin flexible belt moves stably and smoothly. The excellent effect that it can be made is obtained.
