JP 2003-245123 A

  By the way, in the said background art, rattling has arisen in the state in which the tray part of the refill container was engaged with the container main body. Specifically, the vertical dimension of the holding groove at the position where the locking protrusion gets over the holding protrusion and enters into the holding groove is set larger than the vertical dimension of the locking protrusion. However, when the cosmetic container is used or carried, the locking projections are relatively moved in the vertical direction in the holding groove, causing rattling. In order to prevent this rattling, for example, it is conceivable that the holding groove has a tapered shape by gradually reducing the vertical dimension in the vicinity of the tip. In such a case, for example, a refill container is attached. At that time, the locking projections are excessively engaged with each other, and the locking projections are too tightly engaged in the holding grooves, which may make it difficult to disengage them.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a cosmetic container capable of appropriately preventing the refill container from rattling in the engaged state.

  A cosmetic container according to the present invention is a cosmetic container including a refill container that is relatively rotated along an inner peripheral surface of a refill container storage portion of a container body and is detachably attached to the refill container storage portion. A locking projection is provided on the outer peripheral surface of the refill container, and a guide groove into which the locking projection is inserted is formed on the inner peripheral surface of the refill container storage portion, and the refill container storage portion extends from the guide groove. A holding groove is formed to extend continuously around the inner peripheral surface so that the locking protrusion enters and is detachably engaged, and the locking protrusion is inserted into the refill container storage portion. Refill container pushing-up means for pressing the refill container upward to be pressed against the upper edge is provided.

  In addition, a holding protrusion that allows the locking protrusion to enter the holding groove and prevents the locking protrusion from being easily detached from the holding groove is formed in the holding groove. It is characterized by.

The hook means 16 includes a protrusion 16b formed in a recess 16a formed at the front end of the refill body 11, and a hook 16 formed downwardly at the front end of the lid portion 12 toward the recess 16a. And a hook 16c.

  An operation portion 17 is integrally formed at the front end of the lid portion 12 and the upper portion of the hook so as to protrude from the upper surface of the lid portion 12 in a bowl shape. In a state where the refill container 5 is attached to the refill container storage unit 4, the operation unit 17 moves toward the cosmetic tool storage unit 6 at a position above the partition wall 7 between the refill container storage unit 4 and the cosmetic tool storage unit 6. And protrude. The opening / closing operation of the lid portion 12 can be performed while holding the operation portion 17 with fingers. Further, an elastic packing 18 is provided on the inner surface of the lid portion 12, and when the lid portion 12 is closed, the peripheral edge portion of the elastic packing 18 is pressed against the upper end of the peripheral wall 14 of the refill main body 11 and the refill main body 11. To keep it airtight.

  On the outer surface of the peripheral wall 14 of the refill main body 11, a cylindrical locking protrusion 19 is integrally formed so as to protrude laterally in the middle in the vertical direction. In this embodiment, two locking projections 19 are provided and have the same size and shape. One locking projection 19 is arranged on the outer surface of the peripheral wall 14 just next to the front end of the refill container 5 and the other on the opposite side of about 180 degrees. The specific number and shape of the locking projections 19 are not limited to those of the present embodiment, and are not necessarily formed integrally with the peripheral wall 14 of the refill container 5 as in the present embodiment. Instead of, it may be formed and attached as a separate body.

  The concave refill container storage portion 4 formed in the container body 2 has a size and shape that fits the peripheral wall 14 and the bottom portion 13 of the refill body 11 so as to be almost exactly aligned, that is, a circular bottom surface 20 and a cylindrical inner peripheral surface 21. And is partitioned. The refill container 5 is rotated relative to the inner peripheral surface 21 of the refill container storage section 4 and is detachably attached to the refill container storage section 4.

  More specifically, the inner peripheral surface 21 of the refill container storage portion 4 has a guide groove 22 formed in a groove shape downward from the upper end of the inner peripheral surface 21 to a middle position in the vertical direction. Two places are provided. The position of each guide groove 22 is a position corresponding to each of the two locking projections 19 provided on the outer surface 14 of the peripheral wall 14 of the refill main body 11, and when attaching the refill container 5 to the refill container storage portion 4, Stop projections 19 are inserted into these guide grooves 22 from above. In the present embodiment, the guide groove 22 has a wider shape on the upper side than on the lower side so that the locking protrusion 19 can be easily inserted.

  Further, a portion of the container main body 2 adjacent to the refill container storage portion 4, in the present embodiment, on the side opposite to the cosmetic tool storage portion 6 by 180 degrees, is recessed in a groove shape from the upper surface of the container main body 2. A hinge housing recess 23 is formed. When the refill container 5 is attached to the refill container storage portion 4, the hinge portion 15 of the refill container 5 is stored in the hinge storage recess 23. The length dimension of the hinge receiving recess 23 is set to be larger than the length dimension of the hinge portion 15 and is set to a length that allows the rotational movement distance for rotating the refill container 5 when the refill container 5 is attached. ing. The hinge portion 15 of the refill container 5 is not positioned between, for example, the upper surface of the container body 2 and the lid 3, but is provided in the hinge housing recess 23 formed by recessing the upper surface of the container body 2 as in this embodiment. By accommodating, the vertical dimension of the cosmetic container 1 as a whole can be reduced in a compact manner while maintaining the vertical dimension of the refill container 5 to be relatively large.

  From the lower end of the guide groove 22 of the refill container storage unit 4, the direction around the inner peripheral surface 21 of the refill container storage unit 4, that is, the direction in which the refill container 5 is rotated relative to the inner peripheral surface 21 of the refill container storage unit 4. A holding groove 24 is formed by extending continuously in a certain horizontal direction. Each locking projection 19 of the refill container 5 is lowered to the lower end of the guide groove 22, then enters the holding groove 24, and is moved to the back in the holding groove 24 as the refill container 5 rotates. Finally, it is engaged in the retaining groove 24 so as to be freely engaged and disengaged. The height at which the holding groove 24 is provided, that is, the vertical arrangement on the inner peripheral surface 21 of the refill container storage portion 4 is such that when the locking projection 19 of the refill container 5 passes through the holding groove 24, The bottom portion 13 is set so as to elastically abut on a refill container push-up means 25 provided on the bottom surface 20 of the refill container storage portion 4 described later.

  Further, at a position in the holding groove 24 close to the connection portion with the guide groove 22, the holding groove 24 is protruded in a semicircular shape downward from the upper edge of the holding groove 24, that is, the upper wall surface 24 b of the holding groove 24. A protrusion 26 is formed. The holding projection 26 is formed integrally with the upper wall surface 24 b of the holding groove 24, that is, formed integrally with the inner peripheral surface 21 of the refill container storage unit 4. Due to the presence of the holding protrusion 26, the vertical dimension of the holding groove 24 is reduced at the holding protrusion 26. Specifically, the vertical dimension of the holding groove 24 below the holding protrusion 26 is set to be slightly larger than the vertical dimension of the cross section of the locking protrusion 19. The vertical dimension in the other part of the holding groove 24 is set larger than that. When the refill container 5 is rotated, the locking projection 19 is inserted further into the holding groove 24 below the holding projection 26 having the narrowest vertical dimension.

  Further, the depth dimension of the holding groove 24 on the back side of the holding protrusion 26 (the end side of the holding groove 24, the side opposite to the guide groove 22), that is, the back end of the holding protrusion 26 and the end face of the holding groove 24. The distance to 24 a is set to be relatively small, and specifically, is slightly smaller than the diameter of the circular cross section of the locking projection 19. As a result, the locking projection 19 that has passed over the holding projection 26 is locked between the holding projection 26 and the end surface 24a of the holding groove 24 so that it does not move relative to the depth (the position in FIG. 4). C). As a result, the locking protrusion 19 is relatively moved in the depth direction in the holding groove 24 in a state where the locking protrusion 19 is engaged, and in other words, in a state where the refill container 5 is mounted in the refill container storage portion 4. As a result, rattling of the refill container 5 is prevented.

  On the bottom surface 20 of the refill container storage portion 4, three refill container push-up means (hereinafter referred to as push-up means) 25 are formed to push the refill container 5 upward so as to press the locking projection 19 against the upper edge of the holding groove 24. ing. Specifically, both of them are formed as a slit in which a semi-oval outer peripheral portion is punched integrally with the bottom surface 20 in the middle of the circular bottom surface 20 of the refill container storage unit 4 in the radial direction. The thickness, that is, the vertical dimension of the push-up means 25 is set to be smaller than the thickness of the bottom surface 20 of the refill container storage unit 4, that is, the thickness of the bottom surface of the container body 2. A columnar abutting portion 27 that abuts against the bottom portion 13 of the refill container 5 is integrally provided in the vicinity of the arc-shaped tip (radially outer end) of each of the push-up means 25. The base side of the push-up means 25 (the center side of the bottom face 20) is integrally connected to the bottom face 20, and the front end side of the push-up means 25 can be elastically deformed up and down with this root part as a base point.

  The vertical dimension of the contact portion 27 is such that when the locking projection 19 of the refill container 5 is positioned in the holding groove 24, the upper surface of the contact portion 27 elastically contacts the bottom portion 13 of the refill container 5. It is set to press the bottom 13 of the container 5 upward. When the push-up means 25 presses the bottom portion 13 of the refill container 5 upward through the contact portion 27, the locking protrusion 19 of the refill container 5 is the upper edge of the holding groove 24, that is, the upper wall surface of the holding protrusion 26 and the holding groove 24. 24b. Since the push-up means 25 and the contact portion 27 of the present embodiment are formed integrally with the bottom surface 20 of the refill container storage portion 4, labor and cost in manufacturing are compared with the case where they are formed separately and attached. This is advantageous.

  Note that the number, shape, dimensions, and the like of the locking protrusions 19, the guide grooves 22, and the holding grooves 24 are not necessarily limited to those of the present embodiment. For example, the holding groove 24 is not limited to the shape extending in the horizontal direction as in the present embodiment, and may be inclined so as to be slightly lowered. In this case, the push-up means 25 does not necessarily need to press the locking projection 19 against the upper edge in the entire process of passing through the holding groove 24. For example, the locking projection 19 exceeds the holding projection 26 in the holding groove 24. The bottom portion 13 of the refill container 5 may be pressed upward only in the state where it has moved to (engaged state). Further, the guide groove 22 and the holding groove 24 are not necessarily clearly distinguishable as in this embodiment, and may be like a series of single grooves.

  Further, the position, shape, number, and the like of the push-up means 25 are not necessarily limited to those of the present embodiment, and may be provided on the inner peripheral surface 21 of the refill container storage unit 4, for example. Moreover, it is not formed integrally with the bottom surface 20 or the inner peripheral surface 21 of the refill container storage unit 4 but may be formed and attached as a separate body.

  Next, the operation of the cosmetic container 1 according to this embodiment will be described. The cosmetic container 1 of the present embodiment is sold alone or in combination with a cosmetic tool such as a refill container 5 or a puff, and the refill container 5 is attached to the refill container storage unit 4 for use. In order to attach the refill container 5 to the refill container storage section 4, first, as shown in FIG. 2, each locking projection 19 is inserted into the upper end of each guide groove 22 from above the refill container storage section 4. The outer surface of the peripheral wall 14 of the refill container 5 is slid along the inner peripheral surface 21 of the refill container storage part 4 so that the hinge part 15 of the refill container 5 is stored in the hinge storage recess 23 of the container body 2. Thereafter, each locking projection 19 descends in each guide groove 22 (see position A in FIG. 4), and when it reaches the lower end thereof, the refill container 5 is relatively rotated around the refill container storage portion 4 to thereby change each engagement. Each holding protrusion 26 is moved over the stop protrusion 19 and further moved into each holding groove 24.

  When the locking projection 19 is positioned in the holding groove 24, the refill container push-up means 25 elastically abuts against the bottom 13 of the refill container 5 and presses it upward. Press against the top edge of 24. As a result, a click feeling is obtained when each locking projection 19 passes under the holding projection 26 while being pressed against the holding projection 26 (see position B in FIG. 4).

  Each locking projection 19 passes under each holding projection 26 and further moves toward the end face 24a side of the holding groove 24 (see position C in FIG. 4), so that each locking projection 19 enters the holding groove 24. As a result, the refill container 5 is attached to the refill container storage section 4. In the present embodiment, the engagement state of each of the locking projections 19 is inclined by approximately 90 degrees (substantially horizontal direction) at least with respect to the direction of the guide groove (extending substantially in the vertical direction) 22 (substantially vertical direction). In other words, it is maintained by the shape of the holding groove 24 refracted in a key shape with respect to the guide groove 22, so that the locking protrusion 19 does not easily come off from the holding groove 24. Further, the locking protrusion 19 is pressed against the upper edge of the holding groove 24 by the action of the push-up means 25, so that the engagement is more reliably engaged. Furthermore, the presence of the holding projection 26 makes it possible to more reliably engage the locking projection 19 from the inside of the holding groove 24, that is, prevent disengagement. Further, the respective locking projections 19 in the engaged state are pressed against the upper edge of the holding groove 24 by the push-up means 25, so that the respective locking projections 19 do not move relative to each other.

  When removing the refill container 5 for replacement, the refill container 5 is rotated around the inner peripheral surface 21 of the refill container storage portion 4 in the opposite direction to that during the attachment operation. What is necessary is just to carry out by making the latching protrusion 19 get over each holding protrusion 26, make it detach | leave from the holding groove 24, and also let it pass through the guide groove 22, and make it detach | leave upward.

  When the cosmetic in the refill container 5 is used, the hook mechanism 10 is disengaged by the same method as that for a normal cosmetic container 1 to open the lid 3, and the hook means 16 of the refill container 5 is further released. And the lid portion 12 of the refill container 5 may be opened.

  As described above, in the cosmetic container 1 according to the present embodiment, the refill container that is relatively rotated along the inner peripheral surface 21 of the refill container storage unit 4 and is detachably attached to the refill container storage unit 4. 5 is provided with a locking projection 19 on the outer surface of the peripheral wall 14, and a guide groove 22 into which the locking projection 19 is inserted on the inner peripheral surface 21 of the refill container storage portion 4. 4 is continuously extended around the inner peripheral surface 21 to form a holding groove 24 into which the locking projection 19 enters and removably engages, and the refill container storage portion 4 holds the locking projection 19. Since the refill container push-up means 25 that presses the refill container 5 pressed against the upper edge of the groove 24 is provided, it is possible to appropriately prevent the refill container 5 from rattling in the engaged state. .

  In addition, a holding protrusion 26 that allows the locking protrusion 19 to enter the holding groove 24 and prevents the locking protrusion 19 from being easily detached from the holding groove 24 is formed in the holding groove 24. As a result, it is possible to more reliably prevent the locking projection 19 from being removed from the holding groove 24 and, consequently, the refill container 5 from being removed from the refill container storage portion 4, and the locking projection 19 to be A good click feeling can be obtained in combination with the upward pressing force by the refill container push-up means 25 during the rotation operation to enter and engage the holding groove 24.

  The specific shape and the like of the holding projection 26 are not limited to those of the present embodiment, and are not necessarily formed integrally with the inner peripheral surface 21 of the refill container storage portion 4 as in the present embodiment. Instead, it may be formed and attached as a separate body. Further, it is not always necessary to project from the upper side to the lower side as in the present embodiment, and at least the locking projection 19 enters the rear of the holding groove 24, that is, the end surface 24a side. Any shape and size may be used that allows it and prevents it from being easily removed. In addition, in order to obtain a good click feeling in combination with the push-up action of the refill container push-up means 25, at least the locking protrusion 19 enters the depth of the holding groove 24 while passing below the holding protrusion 26 instead of above. In this manner, the holding protrusion 26 may be formed.
