The support frame 29 is attached to an annular recess 30 that is annularly recessed outside the lid piece storage portion 5a by fitting an outer peripheral edge portion 29a by ultrasonic bonding or the like. As a result, the lid piece 19 is floatingly supported by the lid body 5 via the central protrusion 19a so as to be swingable, and seals the rear storage portion 3. In other words, the floating support is such that the inner peripheral edge of the support frame 29 projects inwardly on the lower surface of the lid piece 19 so that the lid piece 19 is supported by the lid piece storage portion 5a and the upper surface of the lid piece 19 Is obtained by contacting only the central protrusion 19a without contacting the lower surface of the lid piece storage portion 5a.

  Further, an annular projecting piece 19b is formed on the lower surface of the lid piece 19 so as to protrude to substantially the same outer diameter as the cutout groove 23c of the cosmetic dish 23 and to be inserted into the cutout groove 23c. The annular projecting piece 19b has a substantially wedge-shaped cross section formed such that the lower end outer side protrudes downward from the lower end inner side, and the inner peripheral surface thereof is formed as an inclined surface 19c. In the closed state of the lid 5, the hermetic seal portion 20 constituted by the inclined surface 25 a of the annular elastic packing 25 in the cutout groove 23 c of the cosmetic dish 23 and the inclined surface 19 c of the annular protrusion 19 b of the lid piece 19 is pressed. By doing so, airtight maintenance in the cosmetic dish 23 becomes possible. The annular elastic packing 25 may be provided not on the cosmetic dish 23 side but on the lid piece 19 side.

  Next, the effect | action of the airtight cosmetics container 1 concerning this embodiment is demonstrated. In order to manufacture the hermetic cosmetic container 1, a pair of push pieces 9 having the arms 10 connected by the connecting pieces 11 are integrally formed. Next, in the space S, the elastic piece 12 is assembled between the raised portion 16 of the bottom wall 7 b of the main body portion 7 and the holding portion 12 b, and the arm 10 is engaged with the left and right cutout portions 8 of the main body portion 7. A pair of integrally formed push pieces 9 is assembled toward the unit 6. Then, the container frame 4 is covered and fixed from above the main body 7 to complete the container main body 4. On the other hand, the annular elastic packing 25 is attached to the cutout groove 23 c of the cosmetic dish 23. Then, the cosmetic dish 23 is fitted into the rear storage portion 3 of the container body 4.

  Further, the lid piece 19 is inserted into the lid piece storage portion 5 a of the lid body 5, and the support frame 29 is fitted to the lid body 5. And what is necessary is just to hinge the container main body 4 and the cover body 5 so that rotation is possible in those rear-end parts.

  When the container main body 4 is opened, the push piece 9 is pressed from the left and right sides of the container main body 4 toward the engagement position 6 with fingers or the like. When the push piece 9 is pushed in, the push piece 9 slides while the connecting piece 11 is flexibly elastically deformed, and each pressing portion 15 is formed on the elastic piece 12 via the arm 10 provided on the push piece 9. The left and right pressed portions 15a move toward the engaging position 6 while being in sliding contact with each other. As a result, the elastic piece 12 is elastically deformed via the left and right pressed parts 15a, the second engaging part 14 moves rearward, and the engagement with the first engaging part 13 is released.

  Subsequently, the left and right push-up portions 18 formed at the front ends of the pair of arms 10 via the hinge pieces 17 slid up while sliding on the ridge-side inclined surfaces 16a, respectively, and the engagement was released. 2 Push up the engaging portion 14 to open the lid 5.

  Thus, by performing the opening operation of the lid 5 in two stages, the engagement release operation and the push-up operation of the lid 5 after the engagement release, the lid can be easily operated with a light pressing force with one hand with good operability. The body 5 can be opened.

  Further, when the container body 4 is opened, not only the push pieces 9 on both the left and right sides are pressed as described above, but the pressing portion 15 on one side can be operated by pressing only the push piece 9 on one side. The elastic piece 12 can be pushed backward to disengage the first engaging portion 13 and the second engaging portion 14, and only the push-up portion 18 on one side rushes up the ridge inclined surface 16a. The second engagement portion 14 that has been disengaged can also be pushed up. Similarly to when the push piece is pressed from both sides, the disengagement operation and the push-up operation of the lid 5 after the disengagement are performed. The opening operation of the lid body 5 becomes possible at a stage. Even in such a case, the lid 5 can be easily and easily opened with one hand.

  Then, when closing the container body 4 with the lid body 5, the lid body 5 is pushed downward from above with fingers or the like, and the first engagement portion 13 is engaged with the second engagement portion 14.

  In the airtight cosmetic container 1 according to the present embodiment, the lid piece 19 for sealing the opening 24 of the cosmetic dish 23 is floatingly supported by the lid 5 so as to be swingable. For this reason, even when the container main body 4, the lid piece 19, and the cutout groove 23 c of the cosmetic dish 23 have variations in manufacturing, the rear housing 3 The annular protrusion 19b of the lid piece 19 is inserted flexibly into the cutout groove 23c of the inner cosmetic dish 23, and the hermetic seal portion 20 can be easily and reliably crimped.

  In the present embodiment, the hermetic seal portion 20 is provided between the cosmetic dish 23 detachably attached to the rear storage portion 3 and the lid piece 19, and the rear storage portion 3 is hermetically sealed by the lid 5. It is trying to seal. Thereby, the structure of the back storage part 3 can be simplified. However, the rear storage portion 3 may be provided with an annular elastic packing, and the rear storage portion 3 may be directly hermetically sealed with the lid 5. In this case, since it is not necessary to provide the annular elastic packing 25 in the cosmetic dish 23, the structure can be simplified.

  In the present embodiment, since the pair of left and right push pieces 9 are integrally formed via the connecting piece 11, the push pieces 9 can be assembled to the container body 2 by a single operation, and the push pieces 9 are assembled individually. Compared to the above, since the assemblability is good, the work can be easily performed. In addition, this shortens the operation time, thereby reducing the manufacturing cost.

  6 to 7 show modifications of the above embodiment. In this modification, the connecting piece 11 is improved. The connecting piece 11 includes a fixed portion 11a formed in a flat plate shape, and a connecting portion 11b extending rearward from the left and right ends of the fixed portion 11a in a substantially L shape. The end of the left connecting portion 11b is connected to the front of the left arm 10, and the end of the right connecting portion 11b is connected to the front of the right arm 10, thereby a pair of push pieces having the arm 10. 9 is integrally formed through the connecting piece 11. Then, if the push piece 9 is pressed, the connecting portion 11b is elastically deformed, the push piece 9 is slid toward the engaging position 6, and if the finger or the like is released from the pressed push piece 9, it is elastically deformed. When the connecting portion 11b of the connecting piece 11 is elastically restored, the push piece 9 is pushed back to the original position.

  In addition, a positioning portion 31 is provided between the connecting piece 11 and the container body 4 to fix the attachment position of the connecting piece 11 to the container body 4. Specifically, the positioning part 31 protrudes upward from the two small holes 32 formed so as to penetrate the fixing part 11 a of the connecting piece 11 in the vertical direction and the bottom wall 7 b of the main body part 7. It consists of two protrusions 33, and the attachment position of the connecting piece 11 to the container body 4 is fixed by fitting these two.

  In the above modification, the positioning of the positioning piece 31 and fixing the position of the connecting piece 11 further improves the ease of assembling the push piece 9, and also the push piece 9 within the container body 4 during use. However, it is possible to prevent fears such as rattling. Other functions and effects are the same as in the above embodiment.

  In the above embodiment, the connecting piece 11 is elastic, but it may be only flexible. In this case, the push piece 9 is pushed back to the original position when the elastic piece 12 is elastically restored.
