[0001]

[Industrial applications]

 The present invention relates to a hermetically-sealed food storage container used as, for example, household products.

[0002]

[Prior art]

 Conventionally, as a closed container for storing food of this kind, as shown in FIGS. 8 to 11, for example, a container body 51 and a lid body 52 made of a synthetic resin are formed, and a sealed step portion 53 is formed on the inner surface of the upper portion of the container body 51. An expanding knob 54 is formed at the center of the upper surface of the lid 52, and the lid 52 can be mounted on the upper surface 53a of the closed step 53 at the peripheral edge of the lid 52, and the inner peripheral surface 53b of the closed step 53 is formed. A sealing member 56 made of a synthetic resin having a flexible elasticity and having a substantially shallow dish shape having a sealing portion 55 capable of being pressed against is fitted, and a pressing portion capable of penetrating the knob portion 54 in the central portion of the upper surface of the sealing member 56. A structure in which 57 is erected is known.

Then, when the forefinger and the middle finger in a bifurcated shape are applied to the back surface of the knob portion 54, the upper surface of the pressing portion 57 is pressed with the thumb, and this pressing causes the central portion of the sealing member 56 to move as shown in FIG. The sealing portion 55 is displaced to the inner side by a slight amount by pressing and bending it downward, and the lid 52 is inserted into the upper inner surface of the container body 51 while maintaining this state, and the sealing portion 55 is closed. When the sealing member 56 is brought into contact with the upper surface 53a of the 53 and the thumb is released from the pressing portion 57, the sealing member 56 restores due to the self-flexible elastic action of the sealing member 56, and by this restoring operation of itself, as shown in FIG. The sealing portion 55 is pressed against the inner peripheral surface 53b of the portion 53 to seal the air inside the container body 51, so that the inside of the container body 51 is sealed by the lid body 52. Further, when the lid 52 is removed, it can be easily removed by reversing the above.

[0004]

[Problems to be solved by the device]

 However, in the above-described conventional structure, when the elastic recovery capacity of the sealing member 56 is deteriorated due to aging or the like, if the knob portion is lifted or the knob portion 53 is pulled up with a strong force, the peripheral edge portion of the sealing member is sealed. The portion 55 may be displaced inward and the lid 52 may float or come off, resulting in an incomplete sealing.

[0005]

[Means for Solving the Problems]

 The present invention is intended to solve such a problem, and its gist is to include a container body and a lid body, and to form a closed step on the inner surface of the upper portion of the container body, and to center the upper surface of the lid body. A knob portion is formed on the cover, and a substantially shallow dish-like flexure having a sealing portion that can be placed on the upper surface of the sealing step portion at the peripheral edge of the lid body and can press the inner peripheral surface of the sealing step portion A sealing member which is made of synthetic resin having elasticity is fitted, and a pressing portion which can penetrate the knob is erected at the center of the upper surface of the sealing member. A closed container for food storage characterized by being configured with a possible locking mechanism.

At this time, as the lock mechanism, a guide groove is formed in the knob portion, a rotating portion is formed in an upper portion of the pressing portion, and the rotating portion is vertically slidably fitted in the guide groove. It is desirable to form a convex portion that can be pressure-contacted on the upper surface of the fitting and gripping portion.

[0007]

[Action]

 Put the bifurcated forefinger and middle finger on the back surface of the knob and press down the pressing part.This pressing presses the central part of the sealing member to bend it downwardly convexly and displaces the sealing part slightly inside. Then, while maintaining this state, insert the lid into the inner surface of the upper part of the container to bring the sealing part into contact with the upper surface of the sealing step, and when the pressing of the pressing part is stopped, the self-flexing elastic action of the sealing member causes The sealing member performs a restoring operation, and by this restoring operation of the sealing member, the sealing portion is pressed against the inner peripheral surface of the sealing step portion, and the inside of the container is sealed by the lid body. By blocking, the elastic deformation of the sealing member that bends downward in a convex shape is blocked, and displacement of the sealing portion inward is blocked.

【Example】

 1 to 7 show an embodiment of the present invention, in which 1 is a container body, 2 is a lid body, and in this case, it is molded from transparent synthetic resin, and a sealing step portion 3 is formed on the inner surface of the upper portion of the container body 1. Has been formed.

Further, an expanding knob 4 is integrally formed in the central portion of the upper surface of the lid body 2, and can be mounted on the upper surface 3a of the hermetically sealed step portion 3 at the peripheral edge portion of the lid body 2 so that the hermetically sealed step portion can be mounted. A state in which the sealing member 6 made of a synthetic resin having a substantially shallow dish-like flexibility and having the sealing portion 5 capable of press-contacting the inner peripheral surface 3b of 3 allows the lid 2 to move up and down slightly by the lip portion 6a. The pressing portion 7 which can be penetrated through the through hole 4a of the knob portion 4 is fixedly provided at the central portion of the upper surface of the sealing member 6.

Reference numeral 8 denotes a lock mechanism. In this case, the lid body 2 is made of synthetic resin having flexibility and is formed in a shape that is slightly curved upward, and the through hole 4 a of the knob portion 4 is formed. Two guide grooves 9 are formed in the inner peripheral surface in the shape of a keyhole, and a rotating portion 10 which is fitted in the through hole 4a so as to be vertically movable is provided on the upper portion of the pressing portion 7 of the elastic claw portion 10a and the pressing portion 7. The keyhole-shaped fastening hole 7a formed in the upper wall allows the pusher 7 to be attached to the pressing portion 7 in a lockable and rotatable manner, and can be vertically slidably fitted to the rotating portion 10 in the guide groove 9 described above. Therefore, two convex portions 11 that can be pressed against the upper surface 4b of the knob portion 4 are formed, and the sealing portion 5 is brought into contact with the upper surface 3a of the sealing step portion 3 to seal the inner peripheral surface 3b of the sealing step portion 3. When the part 5 is pressed, the lower part of the rotating part 10 is formed in the inner groove 6 so that the lower part of the rotating part 10 is depressed. When the lower surface of the rotating portion 10 is lowered and positioned above the upper surface 4b of the knob portion 4, the rotating portion 10 is rotated, and when the finger is released from the rotating portion 10, the elasticity of the lid body 2 is reduced. Due to the restoring action, the bottom surface of the convex portion 11 is pressed against the upper surface 4b of the knob portion 4 to prevent the rotation portion 10 from unexpectedly rotating.

Since this embodiment has the above-described structure, as shown in FIGS. 2, 6 and 7, the rotating portion 10 is rotated with respect to the pressing portion 7 so that the convex portion 11 and the guide groove 9 face each other. In this state, the forked and middle fingers of the fork are placed on the back surface of the knob portion 4 and the upper surface of the rotating portion 10 of the lock mechanism 8 is pushed down by the thumb, and the pushing portion 7 is pushed down by this pushing, By this pressing, as shown in FIG. 6, the central portion of the sealing member 6 is pressed and bent downwardly to displace the sealing portion 5 slightly inside, and the lid body 2 of the container body 1 is maintained while maintaining this state. When the sealing member 5 is inserted into the inner surface of the upper portion and the sealing member 5 is brought into contact with the upper surface 3a of the sealing step portion 3 and the thumb is released from the rotating member 10, the sealing member 6 is restored by the self-flexible elastic action of the sealing member 6. By this self-restoring operation, the sealing portion 5 is pressed against the inner peripheral surface 3b of the sealing step portion 3. As a result, the air in the container body 1 may be sealed, so that the inside of the container body 1 is sealed by the lid body 2. At this time, the lid body 2 resists the elasticity of the lid body 2, 4 and FIG. 5, in this state, the rotating portion 10 of the lock mechanism 8 is rotated to make the convex portion 11 face the upper surface 4b of the knob portion 4, and then the finger is released from the lid body 2. The bottom surface of the convex portion 11 is pressed against the upper surface 4b of the knob portion 4 by the self-elasticity restoring action of the lid body 2, which prevents the downward movement of the pressing portion 7 and the rotation of the rotating portion 10. Therefore, the elastic deformation of the sealing member 6 can be prevented, the inward displacement of the sealing portion 5 can be prevented, the accidental disengagement of the lid 2 can be prevented, and the sealing of the container 1 can be ensured. It is possible to significantly improve the sealing effect.

Further, when removing the lid body 2, the lid body 2 is pushed down with a finger, and the rotating portion 10 is rotated so that the convex portion 11 and the proposed groove 9 are aligned and face each other. Due to the elastic restoring action, the lower part of the rotating part 10 is immersed in the guide groove 6, and in this state, the forked and middle fingers of the fork are put on the back surface of the knob part 4 and the rotating part 10 of the lock mechanism 8 is pressed with the thumb. The upper surface is pushed down, the pushing portion 7 is pushed down by this pushing, and the central portion of the sealing member 6 is pushed by this pushing to bend downward, and the sealing portion 5 is displaced slightly inward. By lifting the lid body 2 while maintaining the state, the lid body 2 can be easily removed.

Further, as the lock mechanism 8, a guide groove 9 is formed in the knob portion 4, a rotating portion 10 is formed in the pressing portion, and the rotating portion 10 is vertically slidably fitted in the guide groove 9. By forming a convex portion that can be pressed into contact with the upper surface of the fitting portion and the knob portion, the structure can be simplified and the manufacturing cost can be reduced.

The present invention is not limited to the above embodiment, and the sizes of the container body 1, the lid body 2 and the knob portion 4, the structure of the lock mechanism 8 and the like are appropriately changed and designed.

[0015]

[Effect of device]

 According to the present invention, as described above, the central part of the sealing member is pressed by the downward pressing of the pressing part to bend the sealing part to the downward convex shape, and the sealing part is slightly displaced inward, and the lid body is maintained while maintaining this state. When the sealing part is inserted into the upper inner surface of the container body and the sealing part is brought into contact with the upper surface of the sealing step part, and then the pressing of the pressing part is stopped, the sealing member restores by the self-flexible elastic action of the sealing member. By the operation, the sealing portion is pressed against the inner peripheral surface of the sealing step portion and the inside of the container is sealed by the lid body.In this state, the locking mechanism prevents the downward movement of the pressing portion to prevent the elastic deformation of the sealing member. It is possible to prevent displacement of the hermetically sealed portion to the inner side, ensure the hermetical sealing, and significantly improve the hermetically sealing effect.

Further, as the locking mechanism, a guide groove is formed in the knob portion, a rotating portion is formed in the pressing portion, and the rotating portion is vertically slidably fittable in the guide groove and the knob portion. By forming a pressable convex portion on the upper surface of the structure, a simple structure can be obtained and the manufacturing cost can be reduced.

As described above, the intended purpose can be sufficiently achieved.
