Description

  The present invention relates to an airtight compact having a double structure in which an inner tray for filling contents is disposed in a container body having a lid, and the inner tray is kept airtight by the inner lid.

  Such compacts are mainly used to store contents containing volatile components, and examples of such contents include cosmetics such as foundations and eye shadows.

In addition, as a conventional structure for improving airtightness, a container with a lid for filling the contents and a container body with a lid for storing the dish with the lid are separately provided. When closing the lid (outer lid), the structure is used to increase the airtightness by pressing the lid (inner lid) of the middle dish against the opening of the middle dish with this outer lid (for example, Patent Documents) 1).
Japanese Patent No. 3778308

  However, the above-mentioned conventional airtight compact has a first release part for releasing the engagement between the outer lid and the container main body, the inner lid and the middle dish on the push piece incorporated on the container main body side for the purpose of improving usability. And a second release portion for releasing the engagement with the inner lid, and the inner lid is opened simultaneously with the opening of the outer lid.

  For this reason, for example, when the push piece is inadvertently pressed when carrying the compact, the engagement between the outer lid and the container body and the engagement between the inner lid and the middle dish are also released, and the contents of the middle dish There is a problem that things touch the outside air. In addition, when the content contains a volatile component, volatilization of the component is inevitable.

  The problem to be solved by the present invention is to solve these problems. The purpose of the present invention is to prevent the lid body of the container body from being opened carelessly, which is caused by that. The object of the present invention is to provide a novel airtight compact in which the lid is not opened and the airtightness can be maintained while maintaining the certain airtightness.

  The hermetic compact according to the present invention includes an inner tray filled with contents, a container main body in which the inner tray is disposed, a lid body that can be opened and closed by the container main body via a pivot, and a pivot. An airtight compact comprising an inner lid that is held openable and maintains the inner tray in an airtight state, wherein the inner lid protrudes outward from an edge facing the pivot of the inner lid, and a through hole is formed. A collar part, a lower base having a claw part that fits into a through hole of the collar part, and fitting to the lower surface of the collar part, and a pivotal side of the inner lid of the lower base are connected via a thin part An operation piece that can swing the lower side of the lower base with the thin-walled portion as a base point, and the operation piece includes a protruding piece that hangs down toward the bottom of the container body. The operation piece folded back through the thin part on the lower side of the lower base in the inner lid The protruding piece comes into contact, and the protruding piece has an action surface that slides by swinging of the operating piece and pushes up the operating piece to open the inner lid through the lower base. is there.

  The working surface may have a slope that rises as it moves away from the pivot axis of the inner lid. In this case, when the operation piece is swung in the direction of pulling up, the tip of the protruding piece comes into contact with the slope to open the inner lid. Can be pushed up.

  In addition, the inclined surface may be a flat surface or a curved surface as long as the tip of the protruding piece slides up by swinging the operation piece and pushes up so as to open the inner lid, Considering that the inner lid can be efficiently opened while suppressing the swinging of the operation piece, it is preferable to form a curved surface that protrudes outward with respect to the container body.

  Furthermore, the lower base according to the present invention may be configured separately from the collar portion or may be configured integrally. However, in configuring integrally, the lower base is connected to the collar portion via the hinge portion, and It is preferable to fit the lower surface of the collar portion by bending at the hinge portion.

  In addition, according to this invention, the pivot of a cover body and the pivot of an inner lid can be comprised as a different body, or can be comprised as the same pivot.

  According to the present invention, since the mechanism for opening the lid of the container main body and the mechanism for opening the inner lid are configured separately, even if the lid of the container main body is opened, only due to that Since the inner lid is not opened, the airtight state of the intermediate dish can be reliably maintained, and the contents filled in the intermediate dish do not need to be exposed to the outside air. Moreover, when the content contains a volatile component, the volatile component does not volatilize.

  In the present invention, since the operation piece is connected to the lower base through the thin part and can swing on the lower side of the lower base with the thin part as a base point, the material, thickness, and length of the thin part are provided. By appropriately setting, etc., it is possible to secure a large force required to bend the thin portion and a restoring force when it is released.

  That is, in a state in which the state in which the inner lid is closed with respect to the inner dish is maintained by the engaging (fitting) means such as a hook, the reaction force due to the bending of the thin portion is caused by the inner dish and the inner lid. Since the reaction force can be used as a larger engagement force in the engagement means, as the force is applied in the direction in which they are separated from each other, the airtight state of the inner dish can be maintained more reliably, while the fitting means Immediately after being released, the inner lid can be reliably opened as the restoring force of the thin portion exerts a force in the direction of pressing the inner tray and the inner lid away from each other.

  Furthermore, according to the present invention, since the inner lid is opened by pulling up the operation piece, it is possible to prevent unintentional opening of the inner lid without the user's positive pulling operation.

  In addition, when the working surface according to the present invention has a slope that rises as it moves away from the pivot axis of the inner lid, when the operation piece is swung from the thin-walled portion as a base point, the inner plate and the inner lid are pressed against each other. Since a large force acting in the direction of separating can be secured, more reliable opening of the inner lid can be realized.

  Furthermore, in this case, if a curved surface that protrudes outwardly with respect to the container body is formed on the inclined surface, the inner lid can be moved while suppressing the movement of the operation piece on the inclined surface, that is, the operation required for opening the user. It can be opened efficiently.

  In addition, in the present invention, if the lower base is fitted to the lower surface of the flange portion by bending at the hinge portion, the operation piece including the protruding piece is configured as an integrated object with the inner lid, Since it can be assembled, it becomes possible to quickly and mass-produce airtight compacts having the above-described effects.

  In addition, the container main body which concerns on this invention is effective in order to be able to open | release an inner lid, after taking out an applicator, when applicators, such as a puff and an eyeliner, can be arrange | positioned with an intermediate plate.

By appropriately setting the material, thickness, length, and the like of the thin portion 9, the force required to bend the thin portion 9 and the restoring force when it is released can be largely ensured.

  That is, in a state where the state in which the inner lid 5 is closed with respect to the inner tray 2 is maintained by the engagement between the claw portion 2a of the inner tray 2 and the claw portion 5a of the inner lid 5, the thin portion 9 is bent. Engagement of the reaction force between the claw portion 2a of the inner plate 2 and the claw portion 5a of the inner lid 5 by the reaction force exerting a force in the direction of pressing the inner plate 2 and the inner lid 5 away from each other. Can be used as a larger engagement force at the same time, so that the airtight state of the inner tray 5 can be maintained more reliably, while immediately after the engagement between the claw portion 2a of the inner tray 2 and the claw portion 5a of the inner lid 5 is released. Since the restoring force of the thin-walled portion 9 presses the inner tray 2 and the inner lid 5 and exerts a force in the direction of separating them from each other, the inner lid 5 can be reliably opened.

  Furthermore, according to the cosmetic compact according to the present invention, since the inner lid 5 is opened by pulling up the operation piece 10, it is possible to prevent the user from unintentionally opening the inner lid 5 without an active pulling operation. be able to.

  Further, the working surface 10 according to the present embodiment has an inclined surface 13f that rises away from the pivot S2 of the inner lid 5, so that when the operating piece 10 is swung with the thin portion 9 as a base point, the inner plate 2 and the middle plate 2 Since it is possible to ensure a large force acting in the direction in which the lid 5 is pressed and separated from each other, a more reliable opening of the inner lid 5 can be realized.

  Furthermore, if the curved surface that protrudes outwardly with respect to the container body 1 is formed on the inclined surface 13f as in this embodiment, the movement of the operation piece 10 on the inclined surface 13f, that is, the operation required for opening the user is suppressed to a small level. In addition, the inner lid 5 can be efficiently opened.

  In addition, the cosmetic compact according to the present invention is such that the lower base 8 is joined to the lower surface 6f of the collar portion 6 by bending at the hinge portion H, so that the operation piece 10 including the protruding piece 11 can be placed inside. Since it is configured as an integral body with the lid 5 and can be easily assembled, it is possible to quickly and mass produce an airtight compact that exhibits the above-described effects.

  In addition, when the container main body which concerns on this invention can arrange | position the applicator M, such as a puff and an eyeliner, with the inner tray 2 like the same form, after taking out an applicator, the inner lid | cover 5 is attached. It is effective because it can be opened.
