Description

  The present invention relates to an airtight container suitable for containing contents such as highly volatile cosmetics.

Conventionally, various types of cosmetic containers have been proposed as an airtight container such as a cosmetic container for storing cosmetics containing volatile components in order to maintain the airtightness of the interior. For example, there is a compact container shown in FIG. The compact container includes a container body 41 in which a dish part 41a is formed at the center of the upper surface and the dish part 41a is filled with cosmetics 41b, and a lid body 42 that covers the upper surface of the container body 41. An annular gasket 43 is fixed to the top surface of the lid body 42. And in the closed state, the airtightness is maintained by pressing the annular gasket 43 on the outer peripheral portion of the dish portion 41a of the container body 41 (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-272012

  However, in the above-described compact container, in the closed state, the portion surrounded by the container main body 41, the top surface of the lid body 42, and the annular gasket 43 is in an airtight state. Sometimes it is necessary to open the lid with a strong force. Moreover, since the rear end portion of the container body 41 and the rear end portion of the lid body 42 are hinge-connected when the lid is opened, the annular gasket 43 is not separated from the upper surface of the container body 41 as far as the rear portion. There is no time to be pressed against the upper surface of the main body 41, and the airtightness cannot be maintained due to damage or the like earlier.

  The present invention has been made in view of such circumstances, and an object thereof is to provide an airtight container that can be opened with a small force and that can maintain airtightness for a long period of time.

In order to achieve the above object, an airtight container according to the present invention includes a container main body having a recess formed on the upper surface, a lid that covers the upper surface of the container main body, and an inner dish accommodated in the recess of the container main body. A cosmetic container in which a hinge connecting portion protruding downward from the rear end portion of the lid body is rotatably connected to the rear end portion of the container body, and is along the peripheral side wall of the inner plate A sliding member that is slidable in the front-rear direction, a belt-like connecting member that connects the sliding member to the hinge connecting portion of the lid so as to be rewound, and the middle plate when the sliding member moves backward And raising and lowering means set to lower the inner tray when the slide member moves forward, and tilting the lid forward to rotate the hinge connecting portion in the closing direction. Roll the belt-like connecting material around the hinge connecting part and slide it The first aspect in which the member is moved rearward, the middle dish is raised by the lifting means in this state, and the upper surface of the middle dish is brought into airtight contact with the lower surface of the lid body, and the lid body is tilted to the rear side. By rotating the hinge connecting portion in the opening direction, the belt-like connecting member is fed forward, the slide member is moved to the front side, and the second plate is lowered by the lifting means in that state. The configuration is such that it can be selected.

  That is, the hermetic container of the present invention includes a slide member that is slidable in the front-rear direction along the peripheral side wall of the inner tray (accommodated in the recess of the container body), and the slide member as a hinge of the lid. A belt-like connecting member that is connected to the connecting portion so as to be rewound, and an elevating means for elevating and lowering the inner tray. Then, the lid is tilted forward and the hinge connecting portion is rotated in the closing direction, so that the belt-like connecting member is wound around the hinge connecting portion and the slide member is moved backward. A first mode in which the middle plate is raised and the upper surface of the middle plate is brought into airtight contact with the lower surface of the lid body, and the lid body is tilted rearward to rotate the hinge connecting portion in the lid opening direction. Thus, the belt-shaped connecting member is fed forward, the slide member is moved to the front side, and either one of the second mode in which the inner plate is lowered by the lifting means can be selected. Therefore, in the airtight container of the present invention, when the lid is closed, the middle dish can be raised and the upper surface of the middle dish can be strongly abutted against the lower surface of the lid body in an airtight manner, thus providing good airtightness. Moreover, when the lid is opened, the lid is turned upward and the inner pan is forcibly lowered, so that the inside of the container body is not immediately airtight and can be opened with a small force. The time when the elastic plate for the airtightness such as the annular gasket disposed between the lid and the intermediate plate is immediately separated from the upper surface of the container body and is pressed against the upper surface of the intermediate plate. Is extremely short and can be kept airtight for a long period of time without being damaged.

  If the slide member and the belt-like connecting material are integrally formed of the same resin material or rubber material, the number of parts is reduced, so inventory management and the like are simplified.

  The elevating means is formed with a predetermined interval in the front-rear direction on the spring member for biasing the middle dish upward, a mounting protrusion projecting from the peripheral side wall of the middle dish, and the slide member. A front-side mounting surface is formed at a position higher than the rear-side mounting surface among the two mounting surfaces. In the first aspect, the front-side mounting surface is By moving the mounting surface onto the mounting projection, the mounting projection is raised by the resilient biasing force of the spring member and the intermediate plate is raised. In the second aspect, in the second aspect, When the mounting surface is moved onto the mounting projection, the mounting projection is lowered against the elastic biasing force of the spring member and the intermediate plate is lowered. The upper surface of the inner plate can be strongly pressed and brought into contact with the lower surface of the lid by the biasing force, ensuring airtightness. It can be.

If you integrally fixing the spring member to the bottom surface of the dish in the above, since the number of parts is reduced, inventory control is simplified.

  The elevating means includes a mounting protrusion protruding from the bottom of the container body or the lower part of the peripheral side wall, and a pair of front and rear mounting surfaces formed on the slide member at a predetermined interval in the front-rear direction. Of these two mounting surfaces, the front mounting surface is formed at a lower position than the rear mounting surface, and the inner plate is supported by the slide member so as to be movable up and down. In the aspect, by moving the front mounting surface up to the mounting protrusion, the slide member is raised and the intermediate plate is lifted. In the second aspect, the rear mounting surface is If the slide member is moved down to the mounting protrusion and the intermediate plate is lowered, the spring is not used, so the structure is simplified and the number of parts is reduced. Inventory management is simplified.

A plate spring 25 formed in a conical truncated conical shape is integrally fixed to the bottom surface of the intermediate plate 5, whereby the intermediate plate 5 is elastically attached to the plate spring 25. It is elastically biased upward by the force.

  The slide body 15 is made of Duracon (trade name) and is disposed on the left and right of the inner plate 5. Both the slide bodies 15 are formed by integrally forming a rod-like slide portion (slide member) 16 and a belt-like winding portion 17, and an outer portion of the rod-like slide portion 16 is formed by cutting out the lower frame 4. A groove-like portion formed between the recess 12 and the lower surface of the upper frame 3 is slid only in the horizontal direction (that is, in a state in which it hardly moves in the vertical direction). Therefore, the whole rod-shaped slide portion 16 is also configured to slide only in the horizontal direction (that is, in a state where it hardly moves in the vertical direction).

  Further, as shown in FIGS. 11 to 13, the rod-shaped slide portion 16 has a pair of front and rear notch portions 18 and 19 for a predetermined interval in the front-rear direction (the distance between the both lift projections 22 a and 22 b. And the same distance). The front raising / lowering cutout portion 18 includes a horizontal surface (front mounting surface) 18a extending horizontally from the front end surface 16a of the rod-like slide portion 16, and a front side of the rod-like slide portion 16 from the rear end portion of the horizontal surface 18a. And a taper surface 18b that inclines downward toward the horizontal lower end surface (rear mounting surface) 16b. The rear elevation notch 19 includes a horizontal plane (front mounting surface) 19a having the same height as the horizontal plane 18a, and a horizontal rear side of the rod-shaped slide section 16 from the rear end of the horizontal plane 19a. It consists of a tapered surface 19b that inclines downward toward the lower end surface (rear mounting surface) 16b, and a vertical surface 19c that hangs down from the front end of the horizontal surface 19a. Then, by sliding both the slide bodies 15 in the front-rear direction, both the raising and lowering protrusions 22a, 22b of the inner tray 5 are in contact with and positioned on the front and rear horizontal surfaces 18a, 19a of the both slide bodies 15. And a state in which the front and rear lower end surfaces 16b are contacted and positioned.

  Further, the belt-like winding part 17 can be wound around both small-diameter cylindrical parts 9b of the hinge connecting part 9 of the lid 2, and when the lid 2 is rotated in the closing direction, the hinge connecting part 9 is wound around both small-diameter cylindrical portions 9b so that the rod-shaped slide portion 16 is retracted, and when the lid 2 is rotated in the opening direction, it is wound around both small-diameter cylindrical portions 9b of the hinge connecting portion 9. The rod-shaped slide part 16 is advanced by pushing forward from the state.

  In the above configuration, when the lid is closed, the front and rear horizontal surfaces 18a, 19a of the slide bodies 15 and the lifting projections 22a, 22b of the inner tray 5 are engaged in contact with each other, and in this state, the plate The inner tray 5 is pushed up by the elastic force of the spring 25 (see FIG. 1). At this time, the tip of the airtight convex portion 24 on the upper end surface of the inner tray 5 is pressed against the lower surface of the airtight elastic plate 20 of the lid 2 so that the airtight state in the inner tray 5 is maintained. Further, the belt-like winding portions 17 of both slide bodies 15 are wound around both small diameter cylindrical portions 9 b of the hinge connecting portion 9 of the lid body 2. When the lid 2 is rotated backward from this closed state to open the lid (that is, the lid 2 is rotated in the direction of opening), the belt-shaped winding portions 17 of both slide bodies 15 are pushed forward. The rod-like slide portions 16 of both slide bodies 15 move forward. As a result, against the elastic urging force of the leaf spring 25, the both raising and lowering projections 22a and 22b of the inner plate 5 are pushed down while contacting the tapered surfaces 18b and 19b of the slide bodies 15, The abutment 5 is brought into contact with and positioned at the lower end surface 16b, and the intermediate tray 5 is lowered accordingly (see FIG. 14).

  As described above, in the above embodiment, when the lid is closed, the inner tray 5 is raised and the upper surface of the inner tray 5 and the airtight convex portion 24 are strongly and airtightly applied to the airtight elastic plate 20 on the lower surface of the lid body 2. It can be contacted and has good airtightness. In addition, when the lid is opened, the lid body 2 is rotated rearward and upward, and the inner tray 5 is forcibly lowered. Therefore, the lid 5 is not immediately airtight and can be opened with a small force. In addition, when the lid is opened, the lid 2 and the inner tray 5 are immediately separated from each other. Therefore, the airtight elastic plate 20 is also immediately separated from the upper surface of the inner tray 5 and the airtight convex portion 24, so that the inner plate 5 is quickly removed. Airtightness can be maintained over a long period without being damaged.

  15 and 16 show another embodiment of the hermetic container of the present invention. In this embodiment, a pair of left and right elevation protrusions (mounting protrusions) 31 are formed on the horizontal bottom surface 1c of the recess 1a of the container body 1 with a predetermined interval in the front-rear direction. Both the elevation protrusions 31 are formed with a horizontal upper surface 31a and a tapered surface 31b that inclines downward from the front end of the upper surface 31a toward the front (see FIG. 17). On the other hand, both slide bodies 15 are provided with a groove portion 32 formed at the lower end portions of the inner peripheral surfaces of the left and right side walls of the container body 1 over the entire width in the front-rear direction, and a notch recess portion 22 (in this embodiment) The protrusions 22a and 22b for raising and lowering are not formed in the notch recess 22), and are slidable in the front-rear direction and arranged to be raised and lowered. Further, the upper surface of the notch recess 22 of the middle dish 5 is placed on the upper surfaces of the both slide bodies 15, whereby the both right and left sides of the middle dish 5 are supported by the both slide bodies 15 from below.

  In both the slide bodies 15, an elevation recess 34 is formed in a portion corresponding to the both elevation projections 31 on the horizontal lower end surface (front mounting surface) 16 b of the rod-like slide portion 16. (See FIG. 18). That is, the upper and lower recesses 34 are formed with an upper surface (rear mounting surface) 34a at a portion corresponding to the upper surface 31a of the both lifting protrusions 31, and at the portions corresponding to the both tapered surfaces 31b. A tapered surface 34b is formed so as to incline downward from the front end portion of the upper surface 34a. In this embodiment, the middle frames 3 and 4 are not provided. For this reason, the stopper 11 which prevents the engaging convex part 23 of the inner tray 5 from coming out upward is formed on the container body 1. Other parts are the same as those in the above embodiment, and the same reference numerals are given to the same parts.

  In the above configuration, when the lid is closed, the horizontal lower end surfaces 16b of the rod-like slide portions 16 of the slide bodies 15 are placed on the upper surfaces 31a of the both raising and lowering projections 31 of the container body 1, and in this state, both The slide body 15 rises from the bottom surface 1 c of the container body 1, and the inner tray 5 is pushed up by both slide bodies 15 and rises from the bottom surface 1 c of the container body 1. Thereby, the front-end | tip of the cyclic | annular convex part 24 of the inner tray 5 contact | abuts to the lower surface of the airtight elastic board 20 of the cover body 2 in the press shape, and the airtight state in the inner tray 5 is maintained. Further, the belt-like winding portions 17 of both slide bodies 15 are wound around both small diameter cylindrical portions 9 b of the hinge connecting portion 9 of the lid body 2. When the lid 2 is rotated backward from this closed state to open the lid (that is, the lid 2 is rotated in the direction of opening), the belt-shaped winding portions 17 of both slide bodies 15 are pushed forward. The rod-like slide portions 16 of both slide bodies 15 move forward. As a result, the horizontal lower end surface 16b of the rod-like slide portions 16 of both slide bodies 15 descends while contacting the tapered surfaces 31b of the both raising and lowering projections 31, and reaches the bottom surface 1c of the recess 31 of the container body 1. Along with this, the middle tray 5 is lowered. In this state, both the elevation protrusions 31 of the container body 1 and the elevation depressions 34 of the slide bodies 15 are engaged with each other (see FIG. 19).

  This embodiment also has the same operations and effects as the above embodiment. Moreover, since the leaf spring 25 is not used as compared with the above embodiment, the structure is simplified, the number of parts is reduced, and inventory management and the like are simplified.

  In the above embodiment, the rod-shaped slide portion 16 and the strip-shaped winding portion 17 of the slide body 15 may be formed separately, or the intermediate plate 5 and the leaf spring 25 may be formed separately. Good. Moreover, in the other embodiment described above, both elevation protrusions 31 may be formed on the left and right side walls of the container body 1.
