The specific embodiments of the present invention will be further described by the following examples and accompanying drawings.

Embodiments of the present creation will be described below based on Figs. 1 to 5 . This description is not intended to limit the implementation of the present invention, but is one of the embodiments of the present invention.

As shown in FIG. 1A and FIG. 1B, an airtight crisper 100 according to an embodiment of the present invention comprises an outer casing 1, an inner casing 2, and a button mechanism 3.

The outer casing 1 has a take-up space 11 and a take-up opening 12 that communicates with the front side of the pull-up space 11.

The inner casing 2 is slid through the take-up opening 12 in a pulling direction d, and the inner casing 2 is housed in the drawing space 11 of the outer casing 1. That is, the inner casing 2 is a drawer that is nested on the outer casing 1. The front side of the inner casing 2 has a door cover portion 21 corresponding to the take-up opening 12 when the inner casing 2 is slidably received in the receiving space 11, and tightly closes the receiving opening 12. As shown in FIGS. 3 and 4, the door cover portion 21 is provided with a vent hole 211 that communicates with the accommodating space 22 of the inner casing 2 and the outside of the accommodating space 22. The accommodating space 22 can be used to store items to be saved. When the door cover portion 21 is tightly closed to the receiving port 12, the air inside the accommodating space 22 can be extracted from the air hole 211 by a vacuuming device to prevent the article from being damp, spoiled or deteriorated, thereby prolonging the shelf life of the article. Preferably, the door cover portion 21 is provided with a plurality of air holes 211 for improving the efficiency of vacuuming.

The button mechanism 3 has a pull tab member 31 and a slide member 32 extending from the pull tab member 31. The slider member 31 is disposed outside the door cover portion 21 through the sliding member 32 to retract the inner casing 2 so that the user can hold the inner casing 2 from the outer casing 1 by holding the button member 31. Pull out in 11. The slider member 31 has a sealing abutting portion 311 corresponding to the air hole 211. As shown in FIG. 4, the seal abutting portion 311 is an end surface of the slider member 31, and the area of the seal abutting portion 311 is sufficient to cover the size of the air hole 211. Actually, the present invention is not limited thereto, and the sealing abutting portion 311 may be, for example, a convex portion that protrudes from the end surface of the pull button member 31, and is positioned to correspond to the air hole 211 for blocking the air hole 211. The sliding member 32 includes a threading shaft 321 and a blocking body 322. The threading shaft 321 penetrates a through hole 212 of the door cover portion 21. The blocking body 322 is located at one end of the threading shaft 321 and is disposed to prevent the button mechanism 3 from the inner box. Body 2 is detached. As shown in FIG. 2, the slider member 31 and the stopper body 322 are respectively located at the two ends of the threading shaft 321 , and the stopper body 322 is located in the accommodating space 22 of the inner casing 2 . Of course, this creation is not limited to this. The stopper 322 may also be buried inside the door cover portion 21.

As shown in FIGS. 3 and 4, the button mechanism 3 slides between the outer pull position P1 and the contracted position P2 in the pull direction d with respect to the door cover portion 21.

As shown in FIG. 3, when the slider member 31 is slid to the outer pull position P1 by an external force (for example, the user pulls the button member 31), the slider member 31 is away from the door cover portion 21, and is sealed. The abutting portion 311 is spaced apart from the air hole 211 in the drawing direction d, and the air hole 211 is in a ventilated state. Therefore, the accommodating space 22 of the inner casing 2 communicates with the outside of the accommodating space 22 through the air hole 211. The external gas enters the accommodating space 22 through the air holes 211, and the atmospheric pressure inside and outside the accommodating space 22 is equal. In this state, the user can easily withdraw the inner casing 2 from the drawing space 11 of the outer casing 1.

As shown in FIG. 4, when the slider member 31 is slid to the retracted position P2, the slider member 31 is in contact with the door cover portion 21, and the seal abutting portion 311 is sealed against the door cover portion 21. Specifically, the button mechanism 3 can be pushed to the retracted position P2 by the user or can be fixed to the retracted position P2 by a pressure difference. In detail, when the vacuuming device completes the vacuuming, since the external atmospheric pressure is large, the atmospheric pressure of the accommodating space 22 is small, and the pressure difference between the two will force the button mechanism 3 to move to the retracted position P2 and pull The button member 31 is pressed and attached to the door cover portion 21 in close contact. That is, when the slider member 31 is pressed to the retracted position P2 by the pressure, the seal abutting portion 311 can be sealed against the air hole 211 of the door cover portion 21 to make the air hole 211 into a closed state. As a result, the outside air of the accommodating space 22 does not re-enter the accommodating space 22 through the air holes 211, and the airtight isolation state of the accommodating space 22 can be maintained.

Preferably, when the slider member 31 is located at the outer pull position P1, the stopper body 322 does not cover the opening of the air hole 211 located inside the accommodating space 22 to maintain the ventilating state, and the inner side of the door cover portion 21 has a bump 213. When the slider member 31 is located at the outer pull position P1, the stopper body 322 abuts against the protrusion 213 of the door cover portion 21, and the air hole 211 and the stopper body 322 are spaced apart along the drawing direction d, and the accommodation space 22 of the inner box body 2 is The air hole 211 is communicated with the outside of the accommodating space 22, and the air hole 211 is in a ventilated state. In addition, by designing the size and shape of the stopper 322 and the position at which the door cover portion 21 opens the air hole 211, the stopper 322 does not cover the air hole 211 when it abuts against the door cover portion 21. For example, the length of the stopper body 322 adjacent to one end surface of the door cover portion 21 in a specific direction is smaller than the distance between the two air holes to avoid covering the air hole 211.

Referring to FIG. 1A and FIG. 5, the airtight crisper 100 further includes a cover body 7. The door cover portion 21 has a recess 214, and the cover body 7 is engaged with the recess 214 for providing a vacuuming device. The gas of the accommodating space 22 of the inner casing 2 is extracted. The cover body 7 has a cover hole 71 for providing a nozzle engagement cover body 7 of a vacuuming device.

Referring to FIG. 1A and FIG. 1B again, the airtight crisper 100 further includes at least one magnet 4 disposed on at least one of the outer casing 1 and the inner casing 2 . When the inner casing 2 is received in the receiving space 11 of the outer casing 1, the magnet 4 can assist the outer casing 1 to be more tightly nested with the inner casing 2, so that the inner casing 2 is not easily taken from the outer casing Body 1 is detached. When at least one of the outer casing 1 or the inner casing 2 is composed of a ferromagnetic material, only one magnet 4 may be required. If both the outer casing 1 and the inner casing 2 are non-ferromagnetic materials (for example, thermosetting plastics), at least two magnets 4 are required.

Preferably, the airtight crisper 100 is designed to be stacked with other airtight crisper 100 or other items. Further, as shown in FIGS. 1A, 1B and 2, the airtight crisper 100 further includes a slip preventing member 5 which is provided on the outer surface of the outer casing 1. When the inner casing 2 is subjected to a pulling force in the pulling direction d, a frictional force can be provided between the outer casing 1 and a placement surface of the outer casing 1 by the anti-slip member 5, so as to avoid the outer casing 1 It is displaced by the pulling of the inner casing 2 together by the pulling force. Alternatively, when the airtight container 100 is stacked, the anti-slip member 5 facilitates fixing the outer casing 1 to the originally stacked position, preventing the outer casing 1 from moving and causing the objects stacked thereon to collapse.

Preferably, the airtight type crisper 100 is provided with an airtight member 6 which is disposed on the outer edge of one of the door cover portions 21 so that the door cover portion 21 covers the pull-out port 12, and the door cover portion can be more tightly sealed. 21 Avoid gas leakage from the outer edge and the outer casing 1.

With the above structure, the airtight crisper 100 of the present invention has a fixed box shape and is easy to stack, and the button mechanism 3 is pushed by the atmospheric pressure difference to seal the air hole 211, so that the airtight crisper 100 does not need to be matched. The additional sealing machine can maintain the airtight state of the accommodating space 22, and has a simple structural design, reduced production cost, and does not require a complicated airtight mechanism and a cumbersome sealing process to provide more convenient operation. Further, by fitting the magnet 4 and the airtight member 6, the outer casing 1 and the inner casing 2 of the airtight crisper 100 can be more tightly coupled to maintain the airtight state without being easily broken. That is, it is necessary to apply a certain degree of pulling force to overcome the magnetic force of the magnet 4, and the inner casing 2 is extracted from the drawing space 11 of the outer casing 1, so that the inner casing 2 is not easily externally damaged by vibration or other factors. The casing 1 is detached. Furthermore, in conjunction with the anti-slip member 5, a plurality of airtight crispers 100 are stacked on each other, and when the inner casing 2 of one of the airtight crisper 100 is withdrawn, the anti-slip member 5 can provide sufficient friction The outer casing 1 is allowed to stay in the original position, and is not displaced by the pulling force, causing the objects stacked thereon to collapse. In summary, the airtight crisper 100 proposed by the present invention has various advantages that cannot be achieved by prior art.
