Description

  The present invention relates to a container for holding a stick-shaped cosmetic, and more particularly, to a configuration of a container for a stick-shaped cosmetic that can be replaced without disassembling a receiving cylinder that holds the stick-shaped cosmetic and an inner dish. Is.

  Stick-shaped cosmetic containers with a mechanism that feeds out stick-shaped cosmetics filled inside by rotating the outer cylinder are widely used as cosmetic containers for lipsticks, lip balms, concealers, etc. for ease of use (For example, refer to Patent Document 1 and Patent Document 2).

  A conventional stick-shaped cosmetic container is composed of, for example, an inner tray filled with a stick-shaped cosmetic and a receiving cylinder, an inner cylinder, a spiral cylinder, and an outer cylinder (see FIGS. 1 to 4). FIG. 1a shows a receiving cylinder and a middle dish of a conventional stick-shaped cosmetic container, and FIG. 1b shows a state where the middle dish is fitted to the receiving cylinder (however, the stick-shaped cosmetic is not shown). FIG. 2 shows a state where the inner plate and the receiving cylinder are mounted on the inner cylinder of a conventional stick-shaped cosmetic container. 3a shows a spiral tube of a conventional stick-shaped cosmetic container, and FIG. 3b shows a state in which the spiral tube is mounted in the state of FIG. Further, FIG. 4a shows an outer cylinder, and FIG. 4b shows a state where the outer cylinder is mounted in the state shown in FIG. 3b. Furthermore, FIG. 4c shows the state which expanded the container upper part in the state of FIG. 4b. In the figure, 1 is a receiving cylinder, 2 is an inner dish, 3 is an inner cylinder, 4 is a spiral cylinder, 5 is an outer cylinder, 11 is a small protrusion, 31 is a guide groove, and 32a and 32b are stop cutouts. , 33 indicates a protrusion slip prevention claw, and 41 indicates a spiral groove.

  Among these, a small protrusion 11 is provided on the outer peripheral portion of the receiving cylinder 1, a guide groove 31 is provided on the inner cylinder 3, and a spiral groove 41 is cut on the inner surface of the spiral cylinder 4. Then, the small protrusion 11 of the receiving cylinder 1 moves up and down along the guide groove 31 of the inner cylinder 3 according to the rotation of the spiral cylinder 4 fitted and integrated with the inner side of the outer cylinder. It is a mechanism that appears and disappears. Such stick-shaped cosmetic containers have the following problems.

  That is, in the conventional stick-shaped cosmetic container, when the middle dish 2 needs to be replaced at the time of defective processing in cosmetic molding, the fitting portion between the receiving cylinder 1 and the middle dish 2 must be disassembled. In other words, when the receiving cylinder 1 and the inner tray 2 are to be removed from the inner cylinder 3, the small protrusion 11 is locked to the protrusion removal prevention claw 33 provided in the guide groove 31. This is because it cannot be removed.

  Even if the locking is released, the outer dimensions (including the small protrusions) of the receiving cylinder 1 are larger than the diameter of the upper end opening of the outer cylinder, so that the receiving cylinder 1 and the inner tray 2 can be removed from the container body. Then, since the small projection 11 is locked to the end wall around the opening of the outer cylinder 5, the receiving cylinder 1 cannot be removed. In order to solve this problem, there may be a method in which a part of the end wall is cut away so that the small protrusion 11 is not locked so that the receiving cylinder 1 and the inner tray 2 can be detached from the container body. Since the cylinder 5 constitutes the beauty of a cosmetic container as a product, such a notch is undesirably detrimental to the beauty.

  Therefore, when exchanging the middle dish 2 at the time of defective processing in cosmetic molding, the fitting portion between the receiving cylinder 1 and the middle dish 2 must be disassembled, and only the middle dish 2 must be removed from the container body. As a result, in the part accuracy of the fitting portion between the receiving cylinder 1 and the inner tray 2, the fitting and disassembling are easy, and the accuracy in which the inner tray 2 does not come out of the receiving cylinder 1 during use is required.

  However, there is a limit to improving the accuracy of the parts of the receiving cylinder 1 and the inner tray 2. In fact, when the fitting is strong, an excessive force is applied to the receiving cylinder 1 when the defective molding is disassembled, and the container is When the damage is given or the fitting is loosened, there has been a situation in which the tray 2 comes out of the receiving tube 1 during use.

  The conventional stick-shaped cosmetic container having the above structure is very difficult to use when considering refilling or replacement. That is, as described above, the receiving cylinder and the inner dish are configured so that they cannot be easily removed. Therefore, the replacement of the inner dish itself may be performed after disassembling the cosmetic container or causing damage to the container. I had to do it.

Japanese Patent Laid-Open No. 2001-327330 Japanese Utility Model Publication No. 6-055512

  Accordingly, an object of the present invention is to provide a stick-shaped cosmetic container that can be easily refilled and replaced, but does not have a problem of dropping out of the inner dish during normal use. .

  The present invention is for solving the above-described problems, and includes an outer cylinder, a spiral cylinder, an inner cylinder, a receiving cylinder, and a small projection provided on the outer periphery of the receiving cylinder, which is filled with a stick-shaped cosmetic. Stick-shaped makeup that is guided by a guide groove provided in the inner cylinder and the small projections move up and down by the spiral groove of the spiral cylinder integrated with the inside of the rotatable outer cylinder, and is filled in the inner dish In the stick-shaped cosmetic container for feeding out the material, the upper end of the guide groove is opened, the small protrusion is provided in the lower part of the receiving cylinder, and further, between the upper end of the inner cylinder and the helical cylinder and the upper end opening of the outer cylinder. This is a stick-shaped cosmetic container characterized in that a space is provided in the container.

  The stick cosmetic container of the present invention does not depend on the accuracy of the member fitting portion, and does not pull out the fitted portion with excessive force, but takes out the fitted member itself from the container, In addition, since a new molded product can be set, there is an advantage that both easy refilling and replacement of cosmetics and prevention of dropping out of the inner dish can be achieved.

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

  FIG. 5a shows a receiving cylinder in the present invention, and FIG. 5b shows a state in which the inner tray in the present invention is fitted to the receiving cylinder in FIG. 5a. FIG. 6 shows the inner cylinder in the present invention. 7a shows a state in which the outer cylinder of the cosmetic container according to the present invention is mounted, FIG. 7b shows a state in which a part is cut out in the state of FIG. 7a, and FIG. 7c shows an enlarged upper part of the container in the state of FIG. The state which cut off the part is shown. FIG. 8 shows a state in which a part of a receiving cylinder, an inner dish, and a container body (a spiral cylinder is omitted) is cut out, and FIGS. 9a to 9d show a receiving cylinder in a container body (a spiral cylinder is omitted). And shows a series of operations for mounting the pan. In the figure, 1 is a receiving cylinder, 2 is an inner dish, 3 is an inner cylinder, 4 is a spiral cylinder, 5 is an outer cylinder, 6 is a space, 11 is a small protrusion, 31 is a guide groove, 32a and 32b are Stop notch, 41 is a spiral groove, X is the length of the space between the upper end of the inner cylinder 3 and the upper end opening of the outer cylinder 5, Y is the diameter of the upper end opening of the outer cylinder 5, and Z is the The outer dimensions of the cylinder 1 (including 11 small projections) are shown.

  The stick-shaped cosmetic container of this embodiment is basically the outer cylinder 5, the spiral cylinder 4, the inner cylinder 3, and the receiving cylinder 1 in the same manner as the conventional stick-shaped cosmetic container described with reference to FIGS. And the inner tray 2 filled with the stick-shaped cosmetic material, the upper end of the guide groove 31 is opened, the small protrusion 11 is provided at the lower end of the receiving cylinder, and the upper ends of the inner cylinder 3 and the spiral cylinder 4 The difference is that a space 6 is provided between the upper end opening of the outer cylinder 5.

  That is, the shape of the receiving cylinder 1 used in this embodiment is shown in FIG. 5, but the small protrusion 11 formed on the outer peripheral portion of the receiving cylinder 1 is the receiving cylinder 1 used in a conventional stick-shaped cosmetic container. Although it is formed slightly above the center (see FIG. 1), it is different in that it is formed at the lowermost end of the outer periphery. In this embodiment, the small protrusion 11 is located at the lowermost end of the outer peripheral portion, but this position is a position where the small protrusion 11 can be inserted into and removed from the space 6 of the outer cylinder 5 by tilting the receiving cylinder 1. I just need it.

  Further, in the inner cylinder 3 used in the conventional stick-shaped cosmetic container, the protrusion removal preventing claw 33 is formed at the upper end of the guide groove 31 (see FIG. 2), but as shown in FIG. The shape of the inner cylinder 3 to be used is different in that the upper end of the guide groove 31 is opened.

  Further, in the conventional stick-shaped cosmetic container, the upper end of the inner cylinder 3 and the inner upper part of the outer cylinder 5 are almost in close contact (see FIG. 4c), but as shown in FIG. The difference is that a space 6 is provided between the upper end of the inner cylinder 3 and the inner upper part of the outer cylinder 5. Such a space is obtained by extending the entire length of the outer cylinder 5 of the conventional stick-shaped cosmetic container, or shortening the entire length of the inner cylinder 3 and the spiral cylinder 4, or both. The length X of the space has a margin that allows the small protrusion 11 to be inserted into and removed from the space 6 by tilting the receiving cylinder 1 when both the small protrusions 11 of the receiving cylinder 1 are in the space (see FIG. 9b). In particular, about 3 mm to 5 mm is desirable.

  Next, in this embodiment, a mechanism for inserting and removing the receiving cylinder 1 and the inner tray 2 into and from the container body will be described with reference to FIGS.

  As shown in FIG. 8, the outer dimension Z of the receiving cylinder 1 is larger than the diameter Y of the upper end opening of the outer cylinder 5, so that the receiving cylinder 1 is inserted vertically into the container body while maintaining the posture shown in FIG. However, the end wall around the upper end opening of the outer cylinder 5 becomes a hindrance to the small protrusion 11 of the receiving cylinder 1 and further insertion is prevented.

  Therefore, first, the receiving cylinder 1 is inclined and the small protrusion 11 is obliquely inserted into the space 6 between the upper end of the inner cylinder 3 and the upper end opening of the outer cylinder 5 from one side (see FIG. 9a), and then the inserted small protrusion The other small protrusion 11 is also inserted into the space by returning the receiving tube 1 to the original vertical posture while pressing the side surface of the receiving tube 1 on the 11th side against the peripheral end wall of the upper end opening. (See FIG. 9b).

  After inserting the small protrusion 11 of the receiving cylinder 1 from the upper end opening of the outer cylinder 5, the small protrusion 11 is inserted from the opening of the guide groove 31 at the upper end of the inner cylinder 3, and thereafter the same as the conventional stick-shaped cosmetic container. (See FIGS. 9c and 9d).

  Next, in normal use, the small protrusion 11 of the receiving cylinder 1 moves up and down in the guide groove 31 of the inner cylinder 3 in accordance with the advancement and lowering of the cosmetic material. 11 is a mechanism that engages with a stop notch 32a provided in the upper part of the guide groove 31. Therefore, there is a possibility that the receiving cylinder 1 moves to an upper part from the position and comes out of the opening part of the guide groove 31. Not (see FIG. 9c).

  That is, by rotating the outer cylinder 5 counterclockwise, the small protrusion 11 engaged with the spiral groove 41 of the spiral cylinder 4 integrated with the inner side of the outer cylinder 5 is pushed up, and the receiving cylinder 1 itself is also moved accordingly. Although it goes up, since the stop notch 32a is provided in the upper part of the guide groove 31, the leftward force which was restrained by the left end of the guide groove 31 and the spiral groove 41 until now works, and the small protrusion 11 Is stored in the stop notch 32a, that is, the position indicated by the solid circle, instead of the position indicated by the broken circle in FIG. 9c. Even if the spiral cylinder 4 is further rotated, the small protrusion 11 is restrained by the stop notch 32a and cannot move further upward.

  On the other hand, when removing a used or poorly molded stick-shaped cosmetic from the container body, first, in the state of FIG. 9c, the inner plate 2 is grasped with a jig or the like, and the small protrusion 11 is stopped from the stop notch 32a to FIG. 9c. To the position indicated by the dashed circle. When moved so far, the upper end of the guide groove 31 is open, so that the receiving tube 1 can be moved to the position shown in FIG. 9b. By removing 11 from the upper end opening of the outer cylinder 5 one side at a time, the cosmetic can be easily taken out together with the inner dish 2 at the time of defective processing on the cosmetic molding.

  The stick-shaped cosmetic container of the present invention can be easily refilled and replaced with cosmetics, but has no problem of dropping out of the inner dish during normal use.

  Therefore, as a method that allows parts to be easily replaced from the container when molding is defective and the container body can be reused reliably, it has the effect of protecting resources and controlling waste, and in production, it generates complaints due to process stability and incompatibility. Since the amount of discarded containers is reduced, it is advantageous for cosmetics such as lipstick, lip balm, concealer, skin whitening stick, sunscreen stick, etc. It can be used for.
