Description

The present disclosure relates to a compact container having improved airtightness inside a saucer member for accommodating contents.

Compact containers are generally used as cosmetic containers, but when the contents containing volatile components such as foundation and eye shadow are stored in the saucer member of the container body, between the container body and the lid body. Part of the contents may volatilize through the gap. In order to suppress the volatilization of such contents, a compact container is used in which the upper opening of the saucer member is closed with an inner lid to improve the airtightness inside the saucer container (see, for example, Patent Document 1).

Japanese Patent No. 3778308

In the above-mentioned conventional compact container, if the airtightness inside the saucer is increased, the pressure inside the saucer increases when the inner lid is closed, making it difficult to close the inner lid or raising the inner lid. It was necessary to apply a strong pressing force in order to completely occlude. Further, in order to avoid this, if a groove for bleeding air is provided in the fitting portion between the inner lid and the saucer container, the airtightness inside the saucer container is lowered and the contents are easily volatilized.

In this embodiment, the vertical direction is the vertical direction in FIGS. 1B and 1C, and the horizontal direction is the horizontal direction in FIG. 1B and the direction perpendicular to the paper surface in FIG. 1C. Further, in FIG. 1B, the direction toward the front perpendicular to the paper surface is the front, and the direction toward the back perpendicular to the paper surface is the rear. That is, the left side in FIG. 1C is the front, and the right side in FIG. 1C is the rear. Further, the radial outer side is a direction away from the central axis O along a straight line perpendicular to the central axis O through the central axis O, and the radial inner side is a direction perpendicular to the central axis O through the central axis O. It is assumed to mean the direction toward the central axis O along a straight line.

FIG. 2 is a plan view showing a state in which the lid 4 of the compact container 100 of FIG. 1A is opened. The lid 4 is rotatable around a pin P1 which is a rotation axis. Further, a hook piece 5 is provided on the side facing the pin P1 with the central axis O in between. When the user presses the hook piece 5 radially inward from the state where the lid 4 is closed and the engagement between the lid 4 and the container body 1 is released, the user puts the lid 4 around the pin P1. As shown in FIG. 2, the inner lid 8 can be exposed, and the inner lid 8 can be made removable from the saucer member 2. In the present embodiment, the inner lid 8 plays a role of closing the upper end opening of the saucer member 2 accommodating the contents in an airtightly sealed state, and the frame member 7 and the ceiling provided on the radial inside of the frame member 7. It has a wall 6.

The saucer member 2 is integrally provided with a side portion 2a having a substantially circular cross section and a bottom portion 2e that closes the lower end of the side portion 2a, and a storage space S for accommodating volatile cosmetics is provided inside the side portion 2a. It is formed (see FIGS. 3 and 4). As shown in FIG. 3 and the like, the side portion 2a is gradually reduced in diameter toward the bottom portion 2e, and the engaging protrusion portion 2h slightly protruding outward in the radial direction at the boundary portion between the side portion 2a and the bottom portion 2e. Is formed. By fitting the engaging protrusion 2h into the stepped portion 1h of the edge portion of the through hole 1g formed in the radial center portion of the bottom portion 1e of the container body 1, the saucer member 2 is moved back and forth with respect to the container body 1. , Left and right and height direction.

A peripheral wall 2b is integrally formed on the radial outer side of the side portion 2a of the saucer member 2 via a flange portion 2d extending radially outward from the upper end portion of the side portion 2a. The peripheral wall 2b has a substantially circular shape in a plan view, and the lower end portion of the peripheral wall 2b in the left-right direction protrudes outward in the radial direction to undercut and engage with the inner surface of the side portion 1a on the container body 1 side. The claw portion 2c is formed.

On the radial outer side of the side portion 2a of the flange portion 2d described above, an engaging wall 2g that undercuts and engages with the inner surface of the leg portion 7c of the frame member 7 is erected when the inner lid 8 is closed. Further, the upper end wall 2f of the side portion 2a of the saucer member 2 comes into contact with the outer peripheral surface of the seal wall 6a integrally formed with the top wall 6 described later when the inner lid 8 is closed. In this way, the engaging wall 2g engages with the leg portion 7c of the frame member 7 to maintain the inner lid 8 in a closed state, and the upper end wall 2f of the side portion 2a hits the seal wall 6a of the inner lid 8. The inner lid 8 and the saucer member 2 are hermetically sealed by being in contact with each other.

In the present embodiment, the side portion 2a and the bottom portion 2e of the saucer member 2 are formed of a synthetic resin containing polypropylene as a main material. However, the material of the saucer member 2 is not limited to this aspect, and may be made of various other synthetic resins or metals such as aluminum. Further, the material of the saucer member 2 is not limited to a single material, and a different material such as a metal material may be bonded to various synthetic resin members.

The container body 1 is integrally provided with a bottom portion 1e at the lower end of a side portion 1a having a substantially circular cross section, and a recess 1j for accommodating the saucer member 2 is formed inside the bottom portion 1e. A through hole 1g that penetrates the bottom portion 1e up and down is provided at the center of the bottom portion 1e of the container body 1 in the radial direction. Then, the engaging protrusion 2h protruding radially outward from the bottom 2e of the saucer member 2 is fitted to the stepped portion 1h of the edge portion of the through hole 1g, so that the saucer member 2 is attached to the container body 1 with respect to the container body 1. It is positioned in the front-back, left-right, and up-down directions. Further, the claw portion 2c provided at the lower end of the peripheral wall 2b of the saucer member 2 undercut engages with the engagement protrusion 1b provided on the inner surface of the side portion 1a of the container body 1, so that the saucer member 2 is engaged. It is detachably attached to the container body 1.

Further, the user can remove the saucer member 2 from the container body 1 and replace it by directly pressing the bottom portion 2e of the saucer member 2 through the through hole 1 g of the container body 1 from below. That is, the cosmetic can be refilled. The through hole 1g does not necessarily have to be provided. In the present embodiment, the engaging protrusion 1b is not provided on the entire circumference around the central axis O, but is provided on a part in the circumferential direction.

In FIGS. 3 and 4, reference numeral 4 is a lid body capable of opening and closing the upper end opening of the recess 1j. As shown in FIG. 4, the lid 4 includes a peripheral wall 4a and a top wall 4e that closes the upper end of the peripheral wall 4a. The lid 4 is connected to the container body 1 via a cylindrical pin P1 inserted into a shaft hole 4d located below the rear end of the peripheral wall 4a, and is rotatable around the pin P1.

The lid 4 may be urged by an urging portion (not shown) so that a rotational moment in a direction that rotates backward and is released around the pin P1 acts. With such a configuration, the user presses the hook piece 5 (unlocking member) inward (rearly) in the radial direction to release the engagement between the lid 4 and the container body 1, and the lid 4 is described above. It is released by rotating backward due to the rotational moment of. Further, the user can rotate the lid 4 forward around the pin P1 and engage the hook 4b with the hook 1k provided on the container body 1 to bring the lid 4 into the closed state shown in FIG. .. In the present embodiment, the mirror 19 is fixed to the lower surface of the lid 4.

The saucer member 2 may be configured to be fixed to the container body 1 via the shock absorbing member. With such a configuration, even when an impact is applied to the compact container 100 from the outside, the contents accommodated in the saucer member 2 and the accommodation space S can be protected from the impact.

As shown in FIGS. 3 and 4, the saucer member 2 is closed in an airtightly sealed state by closing the upper end opening with the inner lid 8. The inner lid 8 includes a top wall 6 on a thin plate and a frame member 7 that surrounds the top wall 6 from the outside in the radial direction.

In the present embodiment, the top wall 6 can be formed of an elastic member made of a soft material such as high-density polyethylene (HDPE) or polypropylene (PP). High density polyethylene (HDPE) is a synthetic resin in which the density value of polyethylene as a base polymer is defined in JIS K6922-1: 2018.

By forming the top wall 6 with a synthetic resin containing high-density polyethylene or polypropylene as a main material, the water vapor transmission rate of the top wall 6 can be reduced and the elastic modulus can be reduced. Therefore, even when the volatile contents are housed in the storage space S, the pressure rise when closing the inner lid 8 is increased while suppressing the contents from volatilizing and deteriorating. The inner lid 8 can be easily closed by suppressing the upward displacement of 6.

As shown in FIG. 3 or 4, the top wall 6 is a thin plate-shaped member whose height changes concentrically and wavy toward the outside in the radial direction. On the outer peripheral edge of the top wall 6, a seal wall 6a that seals between the inner lid 8 and the saucer member 2 when the inner lid 8 is closed is integrally formed with the top wall 6. As shown in FIGS. 3 and 4, the seal wall 6a is a member extending radially outward from the lower surface of the outer peripheral portion of the top wall 6 in a U shape. When the inner lid 8 is closed, the seal wall 6a is pushed inward in the radial direction by the upper end wall 2f of the side portion 2a from the state shown by the solid line in FIG. 5, and the upper end wall 2f and the hanging wall 7e of the frame member 7 are pushed. It is sandwiched between and. As a result, a seal region having a width W shown in FIG. 5 is formed between the inner lid 8 and the saucer member 2, so that the contents in the accommodation space S of the saucer member 2 volatilize and leak to the outside. It can be made difficult.

Conventionally, if the inner lid 8 and the saucer member 2 are airtightly sealed, the pressure inside the saucer member 2 rises when the inner lid 8 is closed, making it difficult to close the inner lid 8, or the inner lid 8 is closed after the inner lid 8 is closed. 8 sometimes came up. In the present embodiment, when the pressure in the accommodation space S rises when the inner lid 8 is closed, the top wall 6 formed of the elastic member, which is a soft member, faces upward as shown in FIGS. 3 and 4. It is elastically deformed and acts to absorb the pressure rise (the top wall 6 after elastic deformation is shown by a two-dot chain line). With this configuration, even if the inner lid 8 is closed in a manner capable of maintaining airtightness, the pressure increase in the content accommodating space S is suppressed, so that the inner lid 8 becomes difficult to close or the inner lid 8 is difficult to close after closing. It is suppressed that 8 floats up. In particular, in the present embodiment, since the height of the top wall 6 changes in a wavy shape, elastic deformation is performed so that the height of the wave becomes low when the pressure in the accommodation space S rises. By doing so, the top wall 6 can be greatly displaced upward. Therefore, it is possible to more effectively suppress the pressure increase in the accommodation space S.

The frame member 7 is provided on a disk-shaped frame 7a that surrounds the radial outer side of the top wall 6, a hanging wall 7e that hangs downward from the radial inner end of the frame 7a, and a radial outer side of the hanging wall 7e. A guide wall 7f that guides the upper end wall 2f of the saucer member 2 inward in the radial direction, an upright portion 7b that is erected upward from the frame body 7a, and a portion that hangs downward from the frame body 7a and engages with the saucer member 2. It is provided with a leg portion 7c fixed by undercut engagement with the joint wall 2g, and a bearing recess 7d that receives the pin P2 and rotates the inner lid 8 around the pin P2.

As shown in FIGS. 2 and 3, a knob portion 7g protruding outward in the radial direction is provided at a position in the circumferential direction facing the pin P2 across the central axis O in the vertical portion 7b. As shown in FIG. 2, when the grip portion 7g is picked and pulled upward with the lid 4 open, the engagement between the leg portion 7c of the frame member 7 and the engagement wall 2g of the saucer member 2 is disengaged, and the inside is inside. The inner lid 8 can be opened by rotating the lid 8 around the pin P2.

As shown in FIG. 5 and the like, the outer peripheral portion of the top wall 6 and the hanging wall 7e of the frame member 7 are configured to be undercut engaged. With this configuration, the top wall 6 and the frame member 7 having different elastic coefficients can be easily mounted and handled as one member (inner lid 8).

The lid 4 forms a space inside the lid 4 for storing a cosmetic tool T such as a puff. On the other hand, as shown in FIG. 4, a hook 1k that engages with the hook 4b provided on the lid 4 to prevent the lid 4 from opening is provided on the container body 1 side, and the hooks 4b and 1k are engaged with each other. Can be provided with a hook piece 5 (unlocking member) that is released by pushing the hook piece 5.

The hook piece 5 includes a pressing portion 5a extending in the vertical direction, a base portion 5c extending radially inward from the lower end portion of the pressing portion 5a, and an acting portion 5b extending radially inward from the pressing portion 5a above the base portion 5c. It is equipped with. When the user presses the pressing portion 5a of the hook piece 5 inward from the state of FIG. 4, the base portion 5c moves rearward in the insertion recess 1f provided in the container body 1, and the acting portion 5b moves. It moves upward toward the rear along the inclined portion 1n provided on the container main body 1. As a result, the acting portion 5b pushes up the hook arm 4c of the lid 4, so that the hook 1k and the hook 4b are disengaged, the lid 4 rotates backward around the pin P1, and the lid 4 opens. Will be done. The hook piece 5 is prevented from coming off in the front-rear direction by the claw portion 5d provided on the bottom surface of the substrate portion 5c entering the recessed portion 1 m provided on the lower surface of the insertion recess 1f.

When using the compact container 100 of the present embodiment having the above configuration, first, the hook piece 5 is pushed inward in the radial direction from the state where the lid 4 shown in FIGS. 3 and 4 is closed. As a result, the acting portion 5b of the hook piece 5 moves upward along the inclined portion 1n and pushes up the hook arm 4c upward, so that the hook 4b and the hook 1k are disengaged and the lid 4 is disengaged. It rotates backward around the pin P1 and is released.

Next, the user disengages the engagement between the leg portion 7c of the frame member 7 and the engagement wall 2g of the saucer member 2 by picking the grip portion 7g of the frame member 7 and lifting it upward. As a result, the contact between the upper end wall 2f forming the airtight seal and the seal wall 6a is also released, and the upper end opening of the saucer member 2 is opened.

When the user finishes using the contents in the saucer member 2, the grip portion 7g or the like is grasped again and the inner lid 8 is rotated around the pin P2 to close it. When closing the inner lid 8, as shown in FIG. 5, the inner lid 8 is closed by undercuting the leg portion 7c of the frame member 7 and the engaging wall 2g of the saucer member 2. Can be done. Further, the U-shaped seal wall 6a integrally formed with the top wall 6 is pressed inward in the radial direction by abutting on the inner peripheral surface of the upper end wall 2f from the shape shown by the solid line in FIG. 5, and is shown in FIG. As shown by the two-dot chain line, it is sandwiched between the upper end wall 2f and the hanging wall 7e. As a result, the seal region shown by the width W in FIG. 5 is formed, so that the airtight seal between the inner lid 8 and the saucer member 2 can be reliably performed. Due to this airtight seal, the pressure in the accommodating space S of the saucer member 2 increases when the inner lid 8 is closed, but the volume in the accommodating space S increases due to the elastic deformation of the top wall 6 upward as described above. Therefore, the pressure rise is suppressed. As a result, it is possible to prevent the pressure inside the saucer member 2 from increasing and making it difficult for the inner lid 8 to close, or to prevent the inner lid 8 from floating after being closed.

As described above, in the present embodiment, the saucer member 2 for accommodating the contents, the container body 1 in which the recess 1j for installing the saucer member 2 is formed, and the upper end opening of the saucer member 2 can be closed.

The inner lid 8 has a top wall 6 having an elastic member. The top wall 6 is elastically deformed upward when the inner lid 8 is closed, so that the increase in the internal pressure of the saucer member 2 is suppressed. By adopting such a configuration, when the upper end opening of the saucer member 2 is closed by the inner lid 8, the top wall 6 of the inner lid 8 is elastically deformed upward, and the pressure increase in the accommodation space S can be suppressed. .. Therefore, it is possible to secure the airtightness inside the saucer member 2 and to easily close the inner lid 8.

Further, in the present embodiment, the inner lid 8 further has a frame member 7 that surrounds the top wall 6 from the outside in the radial direction, and the outer peripheral edge of the top wall 6 is covered with the inner lid 8 when the inner lid 8 is closed. A seal wall 6a that seals between the saucer member 2 is integrally formed, and when the inner lid 8 is closed, the seal wall 6a is formed from the side portion 2a (upper end wall 2f) of the saucer member 2 and the frame member 7. It was configured to be sandwiched between the hanging wall 7e and the hanging wall 7e. By adopting such a configuration, the inner lid 8 can be configured by combining the top wall 6 formed of the elastic member which is a soft member and the frame member 7 for securely mounting the tray member 2. can. Therefore, it is possible to suppress the increase in pressure in the saucer member 2 and to mount the inner lid 8 on the saucer member 2 more reliably.

Further, in the present embodiment, the top wall 6 is fixed to the frame member 7 by engaging the outer peripheral portion of the top wall 6 with the hanging wall 7e. By adopting such a configuration, even if the elastic modulus of the top wall 6 and the frame member 7 are different, they can be easily connected and handled as one member (inner lid 8).

Further, in the present embodiment, the top wall 6 is configured so that the height changes concentrically and wavy toward the outside in the radial direction. By adopting such a configuration, the radial central portion of the top wall 6 can be largely displaced upward without being biased in the circumferential direction when the inner lid 8 is closed, so that the pressure increase in the accommodation space S can be efficiently suppressed. can do.

Further, in the present embodiment, the top wall 6 is configured to be formed of a synthetic resin whose main material is high-density polyethylene or polypropylene. By adopting such a configuration, the water vapor permeability of the top wall 6 can be reduced and the elastic modulus can be reduced, so that the contents volatilize even when the volatile contents are housed in the storage space S. It is possible to suppress the pressure increase when the inner lid 8 is closed due to the elastic deformation of the top wall 6 upward while suppressing the deterioration due to the deterioration, so that the inner lid 8 can be easily closed.
