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

  The above conventional airtight compact has a first release part for pushing up the outer lid and releasing the engagement with the container main body on the push piece rotatably incorporated on the container main body side for the purpose of improving the usability, and the inner lid And a second release portion for releasing the engagement with the inner tray to provide a mechanism for simultaneously opening the outer lid and the inner lid.

  However, the compact structure has a structure in which the push piece directly pushes up the inner lid by rotating the push piece. Therefore, when the push piece is operated, the push piece does not have to be pushed into the pushing portion. The force obtained as a force for pushing up the inner lid is smaller than the pushing force applied to the piece, and it may be difficult to release the engagement between the inner lid and the inner tray.

  On the other hand, if the push part of the push piece is widely secured and the distance between the rotation position of the push piece and the push position of the user is increased, the inner lid can be pushed up with a relatively light pushing force, but it is compact. However, if the ratio of the pressing part of the push piece is taken into consideration, even if the pressing part of the push piece is widely secured, the pushing force obtained when the push piece is rotated is not so large.

The problem to be solved by the present invention is that a push piece for releasing the engagement between the lid and the container body is used to operate a release portion provided integrally with the inner tray to push up the inner lid to engage with the inner tray. In the configuration to cancel
The purpose is that the push piece can be pushed in easily and has excellent operability, and the release part formed on the inner tray can be operated reliably to open the lid and the inner lid reliably. It is to provide a new airtight compact.

  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, and is held by the container main body so as to be opened and closed via a pivot, and is engaged with the container main body in a closed state. An airtight compact comprising: a lid body that can be opened and closed via a pivot, and an inner lid that maintains the inner tray in an airtight state; and a push piece that releases the engagement of the lid body by being pushed in. A pressing portion that performs a pushing operation and an extension portion that is connected to the pressing portion and is slidably held in the container main body, and the inner plate has a base portion that is connected to a side wall of the inner plate. A push-up piece is provided that is elastically deformed upward by pushing the push piece and is pushed upward to push up the inner lid.

  According to the present invention, as a configuration that enables elastic deformation of the push-up piece, for example, the push-up piece is made of an elastic material, and elastic deformation is realized by physical properties of the material, or the push-up piece and the base portion The structure which implement | achieves elastic deformation according to a shape by forming a thin part between these is mentioned. The pivot of the lid and the pivot of the inner lid can be configured as separate bodies or can be configured as the same pivot.

  The push-up piece according to the present invention may have a configuration in which a tip end portion thereof is disposed on a side farther than the push piece with the base portion interposed therebetween. Further, the push-up piece according to the present invention may be configured such that the tip end portion is disposed closer to the push piece than the base portion.

  In the present invention, it is preferable that the push-up piece has an inclined surface that assists the push piece to be submerged. Furthermore, it is preferable that the push piece has an inclined surface that assists the dive into an extension of the push piece.

  According to the present invention, by pushing the push piece, the engagement between the lid body and the container main body is released, while the extension part enters the lower side of the push-up piece connected to the inner plate and presses the push piece. The push-up piece is elastically deformed upward. As a result, the push-up piece connected to the inner plate pushes up the inner lid that engages with the inner plate, so that the engagement between the inner plate and the inner lid can be released together with the engagement between the container body and the lid. it can.

  In addition, conventionally, the push piece is configured to directly push up the inner lid by rotating the push piece.Therefore, when operating the push piece, if the push position with respect to the pressing portion of the push piece is not considered, the push piece Whereas the force to push up the inner lid relative to the force applied is insufficient and the engagement between the inner plate and the inner lid may be difficult to disengage, the present invention provides a push piece that slides the container body Because it is configured to sink into the lower side and indirectly push up the inner lid with the push-up piece, when operating the push piece, if you simply push the push piece without considering the push position with respect to the push piece, The engagement with the inner lid can be released.

  Therefore, according to the present invention, the push piece can be easily pushed in, the operability is excellent, and the lid and the inner lid can be reliably opened, which is convenient.

  In the present invention, if the tip of the push-up piece is disposed on the side farther than the push piece across the base, the push piece extension is guided by the bottom surface of the push-up piece and the bottom of the container body. Accordingly, it is possible to prevent the force to be applied to the push-up piece due to the elastic deformation of the extension portion, and to obtain a reliable operation of the push-up piece.

  In the present invention, if the tip of the push-up piece is disposed closer to the push piece than the base, the push piece extension can be set shorter, thereby elastically deforming the extension. Thus, the application of force to the push-up piece can be reliably transmitted without performing the above, and the push-up piece can be reliably operated.

  In addition, if the push-up piece according to the present invention is provided with an inclined surface that assists in the push piece dive, the push piece is easy to dive and the operability is further improved.

  In addition, even if an inclined surface that assists the dive is formed in the extension part of the push piece according to the present invention, the push piece is easily dipped and the operability is further improved.
