  By the way, in Patent Documents 1 and 2, the push piece is not held in the initial position when the first cover is operated from the initial position where the first hook is engaged with the container body side and the outer lid is opened. Because it swings in the hole or in the recessed part, it is returned to the initial position for the first time by closing the inner lid after makeup, so that the swinging movement can be suppressed. In addition, there is a risk that abnormal noise may occur during use.

  On the other hand, in Patent Documents 3 and 4, a leaf spring is separately formed on the push piece so that the push piece can be returned to the initial position to prevent rattling thereof, but another part incorporated into the container body. However, since the leaf spring is provided on the push piece, there is a problem that the manufacture is complicated and the assembling property to the container body is not good.

  The present invention was devised in view of the above-described conventional problems, and the push piece is returned to the initial position without providing a leaf spring or the like separately to the push piece that is a component incorporated in the container body, and the backlash is reduced. An object of the present invention is to provide a cosmetic container capable of preventing sticking and having good productivity.

The cosmetic container according to the present invention is formed integrally with a synthetic resin container main body, and defines a storage portion for storing an inner tray that is opened and closed by an inner lid, in the container main body that is opened and closed by an outer lid. The inner lid is formed integrally with the wall portion through a wall portion, a hollow portion formed in the wall portion, and a slit formed by horizontally penetrating the wall portion from the hollow portion, and is elastically deformed to form the inner lid. An elastic repulsion piece that presses in the opening direction, a push piece that is movably provided on the container body, is detachably disengaged from the outer lid and releases its closed state, and is integrated with the push piece And a pressing piece portion that elastically deforms the elastic repulsion piece against the repulsive force as it moves.

  In the cosmetic container according to the present invention, without separately providing a leaf spring or the like to the push piece that is a component incorporated in the container body, the push piece can be returned to the initial position to prevent rattling thereof, The productivity can also be improved.

Hereinafter, a preferred embodiment of a cosmetic container according to the present invention will be described in detail with reference to the accompanying drawings.

The push piece 10 that is moved and released detachably from the outer lid 3 to release its closed state is formed integrally with the push piece 10, and the elastic repulsion piece 9 is used as the repulsive force with the movement. And a pressing piece portion 11 that elastically deforms against it. .

  The container body 2 includes an outer frame body 12 and a dish frame 13 formed of a hard synthetic resin material such as ABS resin. The outer frame body 12 is formed by an annular peripheral wall 12b erected integrally with the periphery of the bottom wall 12a. A cutout portion 14 reaching the bottom wall 12a is formed at the center of the front end portion of the peripheral wall 12b, that is, at the center of the front end portion of the cosmetic container 1.

  On the other hand, the dish frame 13 has an annular flange portion 13a along the peripheral wall 12b of the outer frame body 12 and a front end portion to a rear end portion, that is, a cosmetic container at the center so that the inside of the annular flange portion 13a is divided into left and right. A central flange portion 13b that extends from the front end portion toward the rear end portion, and a right side edge of the central flange portion 13b along the inner edge of the right side portion of the annular flange portion 13a. The formed right annular peripheral wall 13c and the left annular peripheral wall 13d suspended from the flange portions 13a and 13b from the left edge of the central flange portion 13b along the inner edge of the left portion of the annular flange portion 13a are integrally formed. The dish frame 13 includes the central flange portion 13b and right and left annular peripheral walls 13c and 13d suspended from the central flange portion 13b. The partition wall 7 of the hollow structure that partitions the outer frame body 12 to the left and right are formed integrally.

  The dish frame 13 is attached to the outer frame body 12 via a fitting portion 15 provided between the outer frame body 12 and the annular flange portion 13a at the upper end of the peripheral wall 12b of the outer frame body 12 It is locked while covering this. On the right side partitioned by the partition wall 7, a right-side annular peripheral wall 13c is surrounded on the bottom wall 12a to form a cosmetic storage part 17 such as a puff 16, and on the left side is a left side on the bottom wall 12a. A storage portion 6 for storing the inner tray 5 is defined by being surrounded by the annular peripheral wall 13d.

  Further, the annular flange portion 13 a of the dish frame 13 is formed with a window portion 18 that passes through the annular flange portion 13 a and communicates with the cutout portion 14 at a position corresponding to the cutout portion 14. Further, the partition wall 7 is formed with a recessed portion 19 in a form in which the height of the partition wall 7 is lowered at a substantially central portion in the front-rear direction.

  An outer lid 3 for opening and closing the container body 2 configured as described above is rotatably attached to the rear end portion of the container body 2 through a hinge 20. At the front end portion of the outer lid 3, a hook piece 22 having a locking projection 21 is formed in a hanging manner so as to correspond to the window portion 18. An end plate 23 is attached to the inner surface of the outer lid 3.

  On the other hand, a refill container 24 composed of the inner lid 4 and the inner tray 5 is detachably accommodated in the accommodating portion 6. The intermediate dish 5 is formed by integrally standing an annular peripheral side portion 5b on the periphery of the bottom portion 5a, and the cosmetic P is filled therein. On the other hand, the inner lid 4 is formed in a flat plate shape, and inner and outer double annular hermetic seal portions 25 and 26 for hermetically sealing the inside of the inner tray 5 are formed on the back surface thereof. The inner first hermetic seal portion 25 enters the inner tray 5 by covering the inner lid 4 with the inner tray 5 and is slidably contacted with the inner peripheral edge at the upper end of the peripheral side portion 5b. The outer second hermetic seal portion 26 is pressed against the upper end of the circumferential side portion 5b by covering the inner lid 4 with the inner tray 5.

  The inner lid 4 is pivotally attached to the left side portion of the peripheral side portion 5b via a hinge 27 so that the inner tray 5 can be opened and closed. Further, a flange 28 is formed at the right end of the inner lid 4 so as to cover the recess 19 so as to reach directly above the partition wall 7, and this flange 28 is suspended into the housing 6 from this. An engagement convex portion 29 is formed, and the right side portion of the peripheral side portion 5b of the inner tray 5 accommodated in the storage portion 6 is engaged with the engagement convex portion 29 so as to be freely disengaged. A projection 30 is formed, and the inner lid 4 closes the inner tray 5 and engages the engagement projection 30 with the engagement projection 30, so that the first and second hermetic seal portions 25 and 26 are hermetically sealed. The refill container 24 is closed.

  The refill container 24 is detachably mounted in the storage portion 6 via a fitting portion 31 provided between the refill container 24 and the storage portion 6. In the illustrated example, the hinge 27 is fitted into a recess 32 formed in the left side portion of the annular flange portion 13a.

  The elastic repulsion piece 9 is partitioned by a slit 8 formed horizontally along the front-rear direction from the recessed portion 19 to the front portion of the annular flange portion 13a on the partition wall 7 where the collar portion 28 of the inner lid 4 reaches immediately above. The upper portion of the wall 7 is integrally formed with the upper portion of the wall 7 so as to be elastically deformable like a cantilever in the upward direction, that is, in the direction of pressing the inner lid 4 in the opening direction via the flange portion 28.

  In particular, the elastic repulsion piece 9 is elastically deformed with a strong repulsive force because the dish frame 13 is formed of a hard synthetic resin material. At the tip of the elastic repulsion piece 9 on the recess portion side, a protrusion 33 that abuts against the flange portion 28 from below is formed.

  The push piece 10 moves in the front-rear direction on the bottom wall 12 a between the outer frame body 12 and the dish frame 13, specifically in a space extending from the notch portion 14 to the partition wall 7 having a hollow structure. It is provided freely. The push piece 10 is formed in a box shape whose upper side is opened so as to communicate with the window portion 18, and the front wall 10 a is fitted into the notch portion 14, and the rear wall 10 b is attached to the outer lid 3. A locking projection 34 that is detachably locked to the locking projection 21 of the hook piece 22 is formed.

  When the front wall 10a of the push piece 10 is pushed inward of the outer frame body 12, the push piece 10 moves on the bottom wall 12a of the outer frame body 12 so that the locking projection 34 is detached from the locking projection 21. The piece 10 is detached from the outer lid 3, and as a result, the outer lid 3 is detached from the container body 2 and the closed state is released.

  The pressing piece portion 11 is integrally formed on the rear wall 10 a of the push piece 10 so as to be directly below the elastic repulsion piece 9. In the illustrated example, the pressing piece portion 11 includes a horizontal arm portion 11a protruding rearward from the rear wall 10a, a swinging arm portion 11b that always contacts the elastic repulsion piece 9 from below, and a swinging arm portion 11b. It comprises a bendable thin bent portion 11c connected to the arm portion 11a in a swingable manner.

  The upper and lower surfaces of the swing-up arm portion 11b are formed by tapered surfaces 11d and 11e so that the thickness gradually increases from the bent portion 11c toward the tip. Further, the outer frame body 12 is formed with an adjusting portion for adjusting the movement of the push piece 10 and the pressing piece portion 11. In the illustrated example, the adjusting portion is formed of a raised portion 35 formed integrally with the bottom wall 12a of the outer frame body 12 so as to be positioned immediately below the pressing piece portion 11.

  The raised portion 35 is disposed so as to face the rear wall 10b of the push piece 10, and is formed in a stepped and high position behind the stopper portion 35a and a stopper portion 35a that abuts against the pushed push piece 10 to limit the pushing stroke. And a swing-up part 35b on which the swing-up arm part 11b is placed.

  An inclined surface 35c is formed at the upper end of the swing-up portion 35b so as to be in sliding contact with the tapered surface 11d below the swing-up arm portion 11b. The inclined surface 35c is formed with an inclination that gradually increases from the front toward the rear, and the bent portion 11c is disposed at a lower height than the inclined surface 35c, and the push piece 10 is pushed backward. Accordingly, the swing-up arm portion 11b mounted thereon moves on the inclined surface 35c. At this time, the bent portion 11c lower than the position of the inclined surface 35c is bent deeply, and the swing-up arm portion 11b has a tapered shape. Is swung upward with a larger swing amount.

  Thus, the pressing piece portion 11 is elastically deformed so that the elastic repulsion piece 9 is pushed upward against the repulsive force with a small pushing stroke of the push piece 10. Further, since the pressing piece portion 11 is always in contact with the elastic repulsion piece 9, when the pressing operation of the push piece 10 is released, the pressing piece portion 11 is pushed back downward by the elastic repulsion piece 9. By pushing back the piece portion 11, the front wall 10 a of the push piece 10 is returned into the notch portion 14 or is held in position.

  Next, the operation of the cosmetic container 1 according to this embodiment will be described. When opening the outer lid 3 of the cosmetic container 1 containing the refill container 24 and applying makeup, the front wall 10a of the push piece 10 located at the cutout portion 14 that is the initial position is placed inside the container body 2 with fingers. Press toward

  When the push piece 10 is pushed in, the locking projection 34 of the push piece 10 is released from the locking projection 21 of the hook piece 22, the outer lid 3 is released from the container body 2, and the closed state by the outer lid 3 is released. At the same time, the swing-up arm portion 11b of the pressing piece portion 11 slides backward on the swing-up portion 35b.

  In the sliding process, the swing-up arm portion 11b is gradually swung up by the inclined surface 35c of the swing-up portion 35b, and elastically repels the elastic repulsion piece 9 upward against the repulsive force. The elastically repelling piece 9 that has been elastically deformed pushes up the flange portion 28 of the inner lid 4 upward through the projection 33, and this push-up causes the engagement projection 29 of the inner lid 4 to engage with the engagement projection of the inner tray 5. The inner lid 4 can be slightly opened by being pushed up and released.

  When the push piece 10 is pushed in as described above, the closed state by the outer lid 3 is released and the inner lid 4 is opened. In particular, the inner lid 4 is pushed up by the pressing piece portion 11 through the elastic repulsion piece 9. The outer lid 3 can be pushed up by pushing up the inner lid 4, and both the inner lid 4 and the outer lid 3 can be opened at once by a single pushing operation by the push piece 10. The outer lid 3 can be opened widely by placing a finger on the 3, and the inner lid 4 can also be opened largely in the same manner.

  When the outer lid 3 and the inner lid 4 are opened, when the finger is released from the push piece 10, the elastic repulsion piece 9 elastically deformed by a considerable repulsive force is elastically restored, and the elastic repulsion piece 9 is restored. By the operation, the pressing piece portion 11 is pushed back on the swing-up portion 35b, whereby the pressing piece portion 11 is pushed forward to return the push piece 10 to the notch portion 14 which is the initial position before the pressing operation. it can.

In the cosmetic container 1 according to the present embodiment as described above, the recess 19 is formed in the partition wall 7 of the dish frame 13 formed of a hard synthetic resin material, and the partition wall is formed from the recess 19. An elastic repulsion piece 9 that can be elastically deformed integrally is formed through a slit 8 that is formed by horizontally penetrating 7, and a pressure piece portion 11 that elastically deforms the elastic repulsion piece 9 against the repulsive force. Is formed integrally with the push piece 10, so that it is not necessary to separately form a leaf spring for returning the push piece to the initial position as in the prior art, and therefore the push piece incorporated in the container body 2. 10 can be configured simply, and its manufacturability and assemblability can be improved, and the pressing piece portion 11 is pushed back by the elastic repulsion piece 9 so that the push piece 10 is moved to the initial position. Notches 14 fixedly can be positioned, it can be appropriately prevented its looseness.

  In the present embodiment, the cosmetic container 1 including the left and right storage units 6 and 17 is illustrated, and the case where the elastic repulsion piece 9 is formed on the partition wall 7 has been described. Of course, an elastic repulsion piece may be formed on the peripheral wall of a cosmetic container having one storage portion, and the elastic repulsion piece may be elastically deformed by the pressing piece portion of the push piece.
