Description

  The present invention relates to a stick-shaped cosmetic container, and more specifically, a stick-shaped cosmetic container in which only the stick-shaped cosmetic filled therein can be easily replaced, and a stick-shaped cosmetic using the container. It relates to the preparation method.

  Stick-shaped cosmetic containers in which stick-shaped cosmetics filled inside appear by rotating the outer cylinder are cosmetics such as lipsticks, lip balms, and concealers for reasons of ease of use. Widely used as a container.

  A conventional container for stick-shaped cosmetics is composed of an outer cylinder 10, a sleeve 2, and an inner plate 7 filled with a stick-shaped cosmetic, for example, as shown in FIG. Is done. In FIG. 1, the right-side view is a cross-sectional view that shows only the inner dish 7 (however, the stick-shaped cosmetic is not shown), and the left-side view shows a cross-sectional view in which only the sleeve 2 is removed. .

  Among these, a small protrusion 8 is provided in the lower part of the outer surface of the inner plate 7, an inner plate guide groove 3 is provided in the sleeve 2, and a helical groove 11 is cut in the inner surface of the outer cylinder 10. The small protrusion 8 of the inner dish 7 moves up and down along the inner dish guide groove 3 of the sleeve 2 according to the rotation of the spiral groove 11 of the outer cylinder 10, and a stick-like cosmetic material appears and disappears accordingly. Yes.

  In this way, the small protrusion 8 of the inner plate 7 moves up and down along the inner plate guide groove 3 of the sleeve 2 according to the rotation of the outer cylinder 10, but if this moves to any extent, the inner plate 7 eventually becomes the sleeve. Therefore, it is necessary to limit the movement of the small protrusions 8 of the inner dish 7 to a certain range. For this reason, in the conventional stick-shaped cosmetic container, the inner plate 7 is prevented from falling off by closing both ends of the inner plate guide groove 3 or cutting the spiral groove 11 on the inner surface of the outer cylinder to the end. It was.

  The conventional stick-shaped cosmetic container having the above-described structure has no problem when used up, but it is very difficult to use when considering refilling and replacement. That is, since the inner plate is configured not to drop off, the inner plate itself needs to be replaced after the cosmetic container is once disassembled.

  By the way, in recent years, with the spread of resource saving and recycling movement, cosmetics that can be refilled or replaced are preferred. However, for stick cosmetic containers, only stick cosmetics are available due to the above-mentioned circumstances. The actual situation was that no exchangeable product was provided yet.

  Accordingly, the present invention provides a stick-shaped cosmetic container that can be easily refilled and replaced, but does not have a problem of falling off of the inner dish during normal use, and a stick using the container. The subject is a method for preparing a cosmetic.

  As a result of intensive studies to solve the above problems, the present inventors utilize the characteristic that the inner plate moves up and down along either one of the inner plate guide grooves due to the helical groove cut in the inner surface of the outer cylinder. In addition, if a notch is provided in the small projection of the inner plate and a locking protrusion having a specific shape is provided in the sleeve, it is possible to achieve both refilling and replacement and prevention of the inner plate from falling off. The present invention has been completed with the idea that it is possible to prepare sticky cosmetics with few defective products.

  That is, the present invention includes an inner cylinder filled with an outer cylinder, a sleeve, and a stick-shaped cosmetic, and the sleeve has a guide groove having a lower end opened and a locking projection at a lower portion thereof, and the inner dish Has a small protrusion provided with a locking notch, the small protrusion is guided by an inner dish guide groove of a sleeve, and moves up and down by a helical groove on the inner surface of the outer cylinder as the outer cylinder rotates, It is possible to make the stick cosmetic filled in the inner dish appear and disappear, and it is a stick-shaped cosmetic container placed in the locking protrusion, and the shape of the locking protrusion is from top to bottom. A gentle diagonal line toward the guide groove center line, a line parallel to the line forming the guide groove, a line perpendicular to the line forming the guide groove and toward the guide groove center line, and a line parallel to the line forming the guide groove And guide groove A stick cosmetic container, characterized in that it is intended to be configured in a gradual oblique lines back to the line to be formed.

  According to the present invention, a second locking protrusion is provided on an upper portion of the locking protrusion, and the shape of the second locking protrusion is perpendicular to the line forming the guide groove from the top to the bottom, and the guide The above-mentioned stick-shaped cosmetic for a stick-shaped cosmetic as described above, which has a shape composed of a line toward the groove center line, a line parallel to the line forming the guide groove, and a gentle oblique line returning to the line forming the guide groove Container.

  Furthermore, the present invention provides the stick-shaped cosmetic container, wherein the locking notch of the small protrusion and the locking protrusion provided in the guide groove are fitted, and the sealing means is attached to the opening of the sleeve, This is a method for preparing a stick-shaped cosmetic material in which the cosmetic material is filled from the bottom of the container.

  The container for stick-shaped cosmetics of the present invention will not drop off during use, but can be easily replaced by using fingers or a simple jig when the stick-shaped cosmetics are used up. It is. Therefore, it can be advantageously used for cosmetics such as lipsticks, lip balms, concealers, skin whitening sticks, sunscreen sticks, etc., as sticky cosmetic containers that can be saved and recycled.

  Hereinafter, the present invention will be described in more detail with reference to the drawings showing some embodiments of the present invention, but the present invention is not limited thereto.

  FIG. 2 is a drawing showing the structure of one embodiment of the stick cosmetic container according to the present invention. The left figure is a partially cutaway sectional view of the state where the stick cosmetic is stored, and the right figure FIG. 3 is a partially cutaway cross-sectional view showing a state in which the stick-shaped cosmetic is drawn out to the maximum. 3 shows the shape of the sleeve of the cosmetic container, FIG. 4 shows the shape of the inner dish, and FIG. 5 shows the shape of the outer cylinder.

  In the figure, 1 is a stick-shaped cosmetic container, 2 is a sleeve, 3 is an inner dish guide groove, 4 is a locking protrusion, 6 is an end of the guide groove, 7 is an inner dish, 8 is a small protrusion, and 9 is a cosmetic holder. The projection for use, 10 is an outer cylinder, 11 is a spiral groove, 13 is a knob, 14 is a locking notch, and A is a stick-shaped cosmetic.

  The stick-shaped cosmetic container 1 according to the present embodiment is basically the same as described with reference to FIG. 1, and is basically filled with the outer cylinder 10 with the spiral groove 11 cut on the inner surface, the sleeve 2, and the stick-shaped cosmetic. Although it is comprised from the plate | pan 7, it differs in the point by which the shape of the sleeve 2, the shape of the small protrusion 8 provided in the inner plate 7, and the spiral groove 11 of the inner surface of the outer cylinder 10 are cut to the last.

  The shape of the locking protrusion 4 provided on the sleeve 2 used in this embodiment is shown in an enlarged manner in FIG. 6, but in the guide groove 3 of the sleeve 2 from the upper part to the lower part in the direction of the center line of the guide groove 3. A gentle oblique line, a line parallel to the line forming the guide groove, a line perpendicular to the line forming the guide groove and toward the center line of the guide groove 3, a line parallel to the line forming the guide groove, and the guide groove Consists of gentle diagonal lines that return to the line forming More simply, the upper base of the trapezoid has a shape in which the shoulder at the top is partially cut off at a right angle.

  FIG. 7 shows the shape of the upper surface (top surface) of the small protrusion 8 provided on the inner plate 7. The upper surface is the upper part of the third quadrant of the circle (portion a in FIG. 7). The shape is cut out at a right angle so as to remain. And the small protrusion 8 is a short column shape which makes this a bottom face. In other words, it is a shape in which a portion between a portion corresponding to approximately 190 ° to 270 ° of a circle is cut off at right angles from a short cylinder as appropriate as a locking notch.

The small protrusion 8 moves in the guide groove 3 and is retained in the locking protrusion 4. For this purpose, the diameter x of the small protrusion 8, the width w of the guide groove, the locking protrusion There must be the following relationship between the distances y and y 'on the opposite side of the flat part and the guide groove.

w ≥ xy ≤ xy '<x (where w ≠ y)

  That is, in order for the small protrusion 8 to move smoothly in the inner dish guide groove 3, the width of the guide groove 3 needs to be the same as or larger than the diameter of the small protrusion 8. In order for the protrusion 8 to be securely placed in the locking protrusion 4, the distance between the protruding flat portion of the locking protrusion 4 and the guide groove opposite side is made smaller than the diameter of the small protrusion, and the material of the sleeve 2 (metal) Elastic stress corresponding to plastic, etc. must be generated. In actual design, for example, it is necessary to determine experimentally how much y ′ and x are to be large, but in general, when x is about 2 mm, y ′ is less than this. What is necessary is just to make about 1 mm small.

  On the other hand, the upper portion of the third quadrant of the remaining circle in the locking notch 14 of the small protrusion 8 is for smoothly moving to a gentle oblique line toward the center line direction of the guide groove 3. Therefore, it is sufficient to leave the upper part of the third quadrant of the circle about 10 to 20 ° in accordance with the inclination of the oblique line.

  In the stick-shaped cosmetic container of the present invention as described above, when the inner plate 7 is loaded into the sleeve 2, the small protrusion 8 can get over the locking protrusion 4. The locking notch 14 provided on the small protrusion 8 and the locking projection 4 are fitted, and the inner dish 7 does not fall off in a normal state.

  Further, since the small protrusion 8 is firmly held by the locking notch 14 by the locking notch 14, it does not rattle at the detention position when lowered, and after the inner plate 7 is mounted, When filling, there is no generation of defective products due to blurring.

  In addition, although said small protrusion 8 is a short column shape as mentioned above, it is that at least one part of the top | upper surface part and the bottom part of the spiral groove 11 provided in the inner surface of the outer cylinder 10 contact. preferable. As means for bringing a part of the top surface portion of the small protrusion 8 into contact with a part of the spiral groove 13 provided on the inner surface of the outer cylinder, a method in which the center portion of the top surface portion is depressed and contacted only at the outer peripheral portion, For example, a method may be used in which a rib is provided in the portion and contact is made only at the portion. By doing so, it is possible to prevent blurring and the like in the direction perpendicular to the axis of the cylinder, and it is possible to determine the position more reliably, and the small protrusion 8 is always inserted into the inner dish guide groove 3 when descending. The force approaching to the left side works, and the retaining effect of the locking projection 4 can be obtained with certainty. Moreover, since moderate resistance works, it can give a high-grade feeling of use.

  Further, as shown in FIG. 8, a stick that is easier to use is provided on the inner plate 7 by providing a knob 13 having a length protruding from the sleeve 2 when the small protrusion 8 is placed in the locking protrusion 4. Container for cosmetics. By providing such a knob 13, it becomes easy to take out the inner dish 7 from the sleeve 2. That is, after the inner plate 7 is once mounted on the sleeve 2, the locking notch 14 provided in the small protrusion 8 and the locking projection 4 are fitted, and the inner plate 7 is dropped from the guide groove end 6 in a normal state. However, it is necessary to remove the inner plate 7 when, for example, the inner plate 7 is replaced (refilled) or there is a defective product. At this time, if there is a knob 13 as described above, the locking notch 14 and the locking protrusion 4 of the small protrusion 8 are removed by twisting it to the right with a finger or the like, and the sleeve 2 is elastically deformed. When the gap between the guide grooves 3 is slightly opened, the inner tray 7 is detached from the sleeve 2 and can be taken out from the guide groove end portion 6. The length of the knob 13 protruding from the sleeve is not particularly limited, but is preferably about 1 mm or more, more preferably about 2 mm or more.

  In order to prepare a stick-shaped cosmetic using the stick-shaped cosmetic container of the above aspect, the inner dish 7 is filled with a stick-shaped cosmetic composition (hereinafter referred to as “cosmetic composition”) and solidified in advance. This may be mounted in the sleeve, but conversely, the cosmetic composition is not filled, and after the inner dish 7 having no bottom is mounted in the stick-shaped cosmetic container 1, the molten makeup A stick-shaped cosmetic may be prepared by filling a predetermined amount of the cosmetic composition into the sleeve 2 or the inner dish 7 from the bottom of the cosmetic container 1 and solidifying it by cooling or the like.

  In this case, the sleeve 2 is used with the sealing means 15 attached to its opening, and this state is shown in FIG. In FIG. 9, as shown on the right side, after fitting the small protrusion 8 of the empty inner dish 7 to the locking protrusion 4, this is turned upside down, from the bottom of the stick-shaped cosmetic container, The heated and melted cosmetic composition is filled. This filled cosmetic composition fills the space formed by the sealing means 15, the sleeve 2, and the inner dish 7, and then solidifies by cooling.

  Then, after solidification, as shown on the left side of FIG. 9, the sealing means 15 is removed and the outer cylinder 10 is rotated to raise the inner dish 7 and release the cosmetic from the sleeve 2 to make the stick-like makeup. It is assumed to be a product. At the time of releasing, the flat portion on the locking protrusion 4 is moved at the beginning of the movement of the small protrusion 8, so that the inner dish 7 itself moves only upward, and the stick cosmetic filled therein No rotational movement is added. The stick-shaped cosmetic is easily broken when a rotational motion is applied when it is released from the sleeve 2, but if the stick-shaped cosmetic container of the present invention is used, the force that the stick-shaped cosmetic receives upon releasing is only upward. Because there is, it becomes possible to suppress the occurrence of defective products due to breakage,

  Next, a stick cosmetic container according to another embodiment of the present invention will be described.

  FIG. 10 is a drawing showing the structure of another embodiment of the stick cosmetic container according to the present invention. The left figure is a partially cutaway sectional view of the state where the stick cosmetic is stored, and the right figure. FIG. 3 is a partially cutaway cross-sectional view showing a state in which the stick-shaped cosmetic is drawn out to the maximum. FIG. 11 is a drawing showing the shape of the sleeve of the cosmetic container.

  In the figure, 1 to 4 and 6 to 15 are the same as described above, and 5 indicates a second locking protrusion.

  In this aspect, a second locking projection 5 is further provided on the upper portion of the locking projection 4 of the sleeve 2, and the shape of the second locking projection 5 is a line that forms the guide groove 3 from top to bottom. The shape is composed of a line perpendicular to the center line of the guide groove 3, a line parallel to the line forming the guide groove 3, and a gentle oblique line returning to the line forming the guide groove, that is, the upper side is a right angle It is characterized by a trapezoidal shape.

  On the other hand, the shapes of the small protrusions 8 and the outer cylinder 10 used in this embodiment may be the same as those shown in FIGS.

In the sleeve 2 of the aspect shown in FIG. 11, the locking protrusion 4 is a temporary indwelling part until the stick cosmetic is manufactured. When the stick cosmetic is used, the second locking protrusion 5 is the original indwelling part. Become. Therefore, the diameter x of the small projection 8 of this aspect, the width w of the guide groove 3, and the distances z, y and y ′ on the opposite side of the guide groove from the flat portion of each locking projection 4, 5 in the sleeve 2 It is necessary to have the following relationship between them.

z <x w ≥ xy ≤ xy '<x
(However, w ≠ y. Also, y ′ = z may be satisfied.)

  Thus, when the locking protrusion 4 and the second locking protrusion 5 are set, the second locking protrusion 5 has a large locking surface with the locking notch 14 of the small protrusion 8 as shown on the left side of FIG. In the case of repeated daily use, the small protrusion 8 can be stably and reliably placed. On the other hand, the locking protrusion 4 has a narrow guide groove 3 at this portion, so that there is no blurring of the small protrusion 4 to the left and right, and as described above, at the beginning of the beginning of the movement of the small protrusion 4 upward. Since there is a flat portion that allows only the movement of the stick cosmetic after the filling and solidification, the rotational movement is not applied when the stick cosmetic is released, and the occurrence of defective products can be reduced. On the other hand, if the second locking protrusion 5 is set as the detention position at the time of filling, the guide groove width is wider than the diameter of the small protrusion 8, so that rotational movement may be applied to the stick cosmetic when the outer cylinder is rotated. May cause non-defective products.

  The stick-shaped cosmetic container of the above aspect is filled with the cosmetic composition to prepare the stick-shaped cosmetic, which may be substantially the same as in the first aspect, but the inner dish 7 having no bottom is stick-shaped. It is mounted in the cosmetic container 1, filled with a predetermined amount of the molten cosmetic composition from the bottom of the cosmetic container 1 into the sleeve 2 or the inner plate 7, and solidified by cooling or the like to be sticked. When preparing a cosmetic, it is desirable to devise its sealing means.

  That is, the locking protrusion 4 is a temporary detention position only at the time of filling, and the subsequent detention position is the second locking protrusion 5, so that when the normal sealing means 15 is used, Part of it will not fit into the sleeve 2. Therefore, as shown in FIG. 13, the position of the sealing surface 16 of the sealing means 15 is provided below the position where the tip of the sleeve hits, and this interval (b ′) is set to the locking surface of the locking protrusion 4 and the second surface. By making it the same as the interval (b) between the locking surfaces of the locking protrusions 5, it is possible to manufacture a stick cosmetic that has the same height as the upper end of the sleeve when stored.

  The stick-shaped cosmetic container of the present invention thus obtained has a stick-like shape that has been conventionally provided except for the shape of the sleeve 2 and the point that the spiral groove 11 of the outer cylinder 10 is cut to the end. The cosmetic container can be prepared in substantially the same material, size, shape and the like. That is, the tip of the inner dish may be in other shapes than a pointed shape, and various metals and plastics may be used for the sleeve 2 to be used, the inner dish 7 and the outer cylinder 10 as in the conventional case. Can do. Furthermore, the outside of the outer cylinder may be covered or covered with metal to form a decorative cylinder, or may be coated by various methods. A lid may be provided. Regarding the materials used for these, any material that can hold the shape, such as paper and ceramics, in addition to metal and plastic, can be used.
