[Industrial applications]
The present invention relates to a compact container suitable for storing volatile cosmetics, and more particularly to a compact container having excellent airtightness.
[0002]
[Prior art]
2. Description of the Related Art As a compact container for storing cosmetics requiring airtightness, a container provided with packing on a lid side has been proposed. As a conventional example of such a compact container, a device disclosed in Japanese Utility Model Laid-Open No. 4-318 shown in FIG. 5 is known.
[0003]
This conventional compact container has a container body 51 in which a storage recess 52 in which a cosmetic 58 is stored and an applicator storage 54 in which an applicator 53 is stored are engraved on the left and right, and a lid 56. A hinge mechanism 60 is provided on the front end face 55 on the opposite side of the hinge part 57 so as to hold the lid 56 in a closed state, with the hinge part 57 provided on the rear end face in the longitudinal direction. In a configuration in which a packing 59 for sealing the inside of the storage recess 52 of the body 51 is adhered to the body 51 or the lid 56, a hinge piece 61 constituting a hinge portion 57 of the lid 56, Is arranged so that the line connecting the hinge piece 61 and the locking mechanism 60 crosses the packing 59.
[0004]
By arranging the packing 59 so as to lie on a line facing the hinge mechanism 57 and the locking mechanism 60 for keeping the lid 56 closed, the sealing by the packing 59 is ensured.
[0005]
[Problems to be solved by the invention]
By the way, in the above-mentioned compact container, since the packing 59 is pressed into the storage recess 52 by the engagement force at the two positions of the hinge portion 57 and the locking mechanism 60, the packing 59 and the storage recess 52 Since the contact strength is uneven and uneven at two points, and the packing 59 is fixed to the body 51 or the lid 56, the deformation of the packing 59 due to the molding distortion of the body 51 and the lid 56 is also applied. The hit becomes more uneven, and it is difficult to reliably maintain airtightness.
[0006]
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a highly airtight compact container in which packing is uniformly applied when a lid is closed to securely seal a cosmetic storage section.
[0007]
[Means for Solving the Problems]
The compact container according to the present invention is a compact container in which each rear portion of a container body and a lid closing the upper surface of the container body is hinged, wherein the container body has an inner plate filled with cosmetics. An accommodating annular wall was provided upright from the bottom plate with a flange at the top, while a through-hole was provided in the lid, and a packing for sealing the cosmetic was attached to the through-hole in the through-hole. A push button is loosely fitted so that it cannot be disengaged and can move up and down, and an engagement piece provided with a projection that engages with the outer peripheral edge of the flange is provided on the back surface of the lid and around the through hole. It is characterized in that it is vertically provided at a plurality of locations at substantially equal intervals, and that a finger hook is further provided on the peripheral wall of the lid.
[0008]
[Action]
In the compact container according to the present invention, when the lid is closed, the packing adhered to the back surface of the push button loosely fitted in the through hole of the lid comes into pressure contact with the upper surface of the inner plate, and the back surface of the lid is In addition, engaging pieces vertically provided at a plurality of locations at equal intervals around the through hole engage with the outer peripheral edge of the flange of the annular wall accommodating the inner plate.
[0009]
As a result of this closing operation, the engagement pieces are arranged at equal intervals, so that the packing is evenly pressed and held on the upper surface of the inner plate, and the push button is loosely fitted in the through hole and can be moved up and down. As a result, the packing easily bends and conforms to the inner plate to keep the cosmetic airtight.
[0010]
Next, when opening the lid, the container body is held with one hand, and the push button is pushed in with the other hand sandwiching the finger hook at the lower end of the peripheral wall of the lid with the top surface of the push button.
[0011]
By this operation, the push button relatively descends from the closed position of the lid, so that the container body is pushed out by the push button to release the engagement with the lid.
[0012]
Then, since the lid can be opened while holding the finger hook and the top surface of the push button, the opening operation and the opening operation of the locking of the lid can be performed at the same time.
[0013]
【Example】
Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.
FIGS. 1 to 4 show a preferred embodiment of a compact container according to the present invention, in which a container body 1 and a lid 2 for closing the upper surface of the container body 1 can be opened and closed by a rear end wall. The container body 1 and the lid 2 are formed by using a general-purpose synthetic resin material such as SAN or ABS.
[0014]
As shown in the figure, a container body 1 composed of a flat box body has a puff storage portion 15 surrounded by a peripheral wall 16, and a makeup provided to stand in front of the puff storage portion 15 and stand up from the bottom plate 3. An annular wall 6 for accommodating the inner plate 4 filled with the material K.
[0015]
The top of the annular wall 6 is formed in a band-shaped flat flange 5 extending over the inside and outside of the annular wall 6, and an inner peripheral edge 27 of the flange 5 engages with a later-described locking groove 17 of the inner plate 4. The locking pieces 18 for fixing the inner plate 4 are vertically provided at a plurality of locations at equal intervals.
[0016]
On the other hand, the outer peripheral edge 28 of the flange 5 engages with a projection 10 protruding from an inner surface of an engagement piece 11 that is vertically provided at a plurality of locations from the back surface around the through hole 9 of the lid 2 to be described later. In order to maintain the state, it is provided around the annular wall 6 so as to protrude outward from the top.
[0017]
The upper surface of the flange 5 supports an inner plate flange 19 provided around the opening of the inner plate 4, and is formed to have substantially the same width as the inner plate flange 19.
[0018]
Further, as shown in FIG. 3, the distal end of the bottom plate 3 of the container body 1 is formed in a concave portion 21 which is curved rearward and cut away. The recess 21 is provided so that a finger can be easily hooked on the finger hook 13 provided at the tip of the lid 2. Therefore, as shown in FIG. 4, if the finger hook 13 is provided so as to protrude forward from the front end of the lid 2, the recess 21 is unnecessary.
[0019]
As shown in FIG. 3, the inner plate 4 stores a cosmetic K such as a foundation, and is formed using a rigid material such as synthetic resin, aluminum, and steel. A locking groove 17 is provided on the periphery, and engages with a locking piece 18. An intermediate plate flange 19 is provided on the opening and supported by the flange 5 to be fixed in the annular wall 6. I have.
[0020]
Next, a makeup mirror 22 is mounted on the back surface of the lid 2 surrounded by the peripheral wall 12 having the lower surface of the tip as a finger hook 13, and the upper surface of the inner plate 4 is closed in front of the mirror 22. A circular through hole 9 into which the push button 8 is loosely fitted is provided.
[0021]
The through-hole 9 has an inner wall in which a rib 23 is provided along an upper opening edge to move the push button 8 up and down, and an inward rib at a lower opening end which prevents the push button 8 from falling downward. 24 are provided around.
[0022]
On the other hand, the push button 8 is formed in a disc shape with a flat upper surface corresponding to the inner plate 4, and has a downward step 25 on the peripheral wall which abuts the inward rib 24 from above to prevent it from falling downward. And outward ribs 26 which come into contact with the inward ribs 24 from below to prevent them from falling upward, are provided around the upper and lower predetermined intervals.
[0023]
Then, the limited distance between the downward step portion 25 and the outward rib 26 is a range in which the push button 8 can move up and down, and the push button 8 is loosely fitted into the through hole 9 so that it cannot be removed. I have.
[0024]
On the back surface of the push button 8, a packing 7 formed by laminating a film on a synthetic resin foam is provided so as to be in contact with the inner plate flange 19 to hermetically seal the cosmetic K. . Incidentally, the packing 7 is not limited to this embodiment, and it goes without saying that a molded packing made of synthetic resin by injection molding may be attached.
[0025]
When the lid 2 of the compact container of the present embodiment configured as described above is closed, the lower surface of the inward rib 24 comes into contact with the outward rib 26, and the push button loosely fits into the through hole 9 of the lid 2. The packing 7 adhered to the back surface of the inner plate 8 comes into contact with the upper surface of the inner plate flange 19, and is provided on the back surface of the lid 2 at a plurality of places at equal intervals around the through hole 9. 11 engages with the outer peripheral edge 28 of the flange 5 of the annular wall 6 containing the inner plate 4.
[0026]
By this closing operation, the engagement pieces 11 are arranged at equal intervals, so that the packing 7 is evenly pressed and held by the inner plate flange 19, and the push button 8 to which the packing 7 is bonded is loosely inserted into the through hole 9. Since the fitting 7 is movable up and down, the packing 7 easily bends and conforms to the upper surface of the inner plate flange 19 to securely hold the cosmetic K in an airtight manner.
[0027]
Next, when the cover 2 is opened, as shown in FIG. 2, the container body 1 is held with one hand, and the finger rest 13 provided at the lower end of the peripheral wall 12 of the cover 2 and the top of the push button 8 are held with the other finger. The push button 8 is pressed in such a manner as to hold the surface.
[0028]
By this operation, the downward step portion 25 descends to the upper surface of the inward rib 24 and comes into contact therewith, and the push button 8 relatively descends from the closed position of the lid 2 so that the container body 1 is pushed out by the push button 8. Then, the engagement with the lid 2 is released.
[0029]
Then, since the lid 2 can be opened while holding the finger hook 13 and the top surface of the push button 8, the engagement between the container body 1 and the lid 2 and the lid opening operation can be performed simultaneously.
[0030]
In this embodiment, the rear end of the short side of the compact container is hinged, and the finger hook 13 is provided at the opposite end. However, the hinged position is not limited to the short side. Needless to say, a configuration may be adopted in which a finger hook 13 is provided at the rear end in the longitudinal direction and the periphery of the annular wall 6 on the opposite side is provided (not shown).
[0031]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to the compact container which concerns on this invention, the through-hole in which the push button to which the packing which seals cosmetics was adhered was loosely fitted so that it cannot be pulled out and was able to move up and down is provided in the lid. On the back side, around the through hole, the engaging pieces that engage with the outer peripheral edge of the flange around the cosmetic storage location were arranged at a plurality of locations at substantially equal intervals, so that the lid was When closed, the packing can be pressed down evenly on the upper surface of the inner plate flange. Can be increased.
[0032]
Furthermore, according to the compact container of the present invention, when opening the lid, hold the container body with one hand, and hold the finger hook at the lower end of the peripheral wall of the lid and the top surface of the push button with the other finger. When the push button is pushed in, the downward step descends to the upper surface of the inward rib and makes contact with it, and the push button relatively descends from the closed position of the lid. The engagement with the body can be released.
[0033]
Then, since the lid can be opened while holding the top surface of the finger hook and the push button, the opening of the engagement between the container body and the lid and the opening operation can be performed at the same time, which is convenient.
