Technical Field
[0001] The utility model relates to a fresh-keeping box, in particular to a fresh-keeping box which can be vented and opened with one hand. Background Art
[0002] Fresh-keeping boxes are not only convenient and practical, but also can store food in different categories. As people's quality of life continues to improve, there are more and more types of fresh-keeping boxes.
[0003] Most existing food storage containers require you to first open the vent hole and then use both hands to press the edge of the lid, requiring multiple steps to open the lid. To simplify opening the lid, a food storage container has been proposed that allows both venting and opening the lid with one hand. However, the applicant has discovered that this container has the following problems: 1. Accidental contact with the handle during use can easily cause the hinged hole to fall off; 2. The recessed structure of the lid is complex to produce in a mold, resulting in high investment costs. Utility Model Content
[0004] In order to solve the above-mentioned defects in the prior art, the present invention proposes an improved fresh-keeping box that can be vented and opened with one hand, and optimizes the structure of the box lid and the air valve buckle. The solution is as follows:
[0005] The lid is opened and deflected, and the top of the lid is rotated to form a rotation point, and the bottom of the lid is rotated to form a rotation point.
[0006] The two groove channels extend close to the side wall of the box cover and penetrate the side wall of the box cover, but the outer circle of the top of the box cover, which is slightly higher, remains complete. This not only makes the box cover free of gaps in the prior art, forming an integrated beautiful appearance, but also simplifies the mold of the box cover and reduces investment costs.
[0007] Furthermore, a protrusion is provided on the air valve buckle, and the air valve sealing glue bean can be detachably mounted on the protrusion. When cleaning or replacing, only the air valve sealing glue bean needs to be removed, which is convenient for use and maintenance.
[0008] Furthermore, the slot includes a transition slot and a connecting slot, and the connecting slot is a vertical waist-shaped hole. This is more conducive to the smooth cooperation between the pin shaft and the slot, so that the air valve buckle is better connected to the box cover for rotation.
[0009] Furthermore, a spherical protrusion is provided on the hinge block near the end of the side wall of the first trough, and a long arc-shaped protrusion is provided at the corresponding position on the side wall of the first trough. The process of closing the air valve buckle and only opening the exhaust hole forms a slight interference to serve as a gear reminder, which is used to remind whether the position is in place.
[0010] Furthermore, two limiting columns are symmetrically provided on the side wall of the first sink to ensure that the air valve buckle and the box cover body are flush in the closed state.
[0011] Furthermore, a mounting groove is provided at the bottom of the box cover, and a sealing strip is provided around the mounting groove. The sealing strip is pressed against the inner wall of the box body to form a water-tight function, which prolongs the preservation time.
[0012] Furthermore, an identification hole is provided on the upper surface of the air valve buckle, and the position of the identification hole corresponds to the sealing plug, which effectively guides the user to align the sealing plug and quickly insert it into the vent hole.
[0013] Compared with the prior art, the advantages of the present invention are as follows:
[0014] The utility model optimizes the structure of the box cover and the air valve buckle, and a first sunken groove is arranged downwardly on the top of the box cover, and a second sunken groove is arranged in the first sunken groove near the end of the box cover side wall, which is opposite to the first sunken groove, so that the first sunken groove is separated from the second sunken groove to form two groove channels, and the two groove channels extend close to the box cover side wall and penetrate the box cover side wall without damaging the top outer ring of the box cover, and the outer ring also maintains a complete structure, which is not only beautiful but also simplifies the box cover molding mold and reduces investment cost; the air valve buckle is an overall U-shaped structure, the opening of the U-shaped structure is adapted to the second sunken groove, and the two parallel protruding end parts of the U-shaped structure are The hinge block is provided with a card slot which is rotatably connected with the pin shaft arranged on the first sink groove. Compared with the existing technology, the force strength of the rotation part is strengthened. At the same time, the upper part of the protruding end part abuts against the outer ring of the box cover to form a protective structure, and the problem of the buckle falling off due to accidental contact will not occur. At the same time, the air valve buckle is arranged as a U-shaped structure as a whole. The upper and lower surfaces of the two parallel protruding ends of the U-shaped structure abut against the box cover and the box body respectively. When the air valve buckle rotates, it forms two levers that work simultaneously to pry the box cover, which is easier and more labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.
[0028] like Figure 1 As shown, the utility model discloses a fresh-keeping box which can be vented and opened with one hand, comprising a box body 2, a box cover 1 and an air valve buckle 3.
[0029] like Figure 2 、 3 As shown, the top of the box cover 1 has a high-medium-outer-low structure, and a first sink groove 11 is set downwardly on the top of the box cover. A second sink groove 12 is set in the first sink groove 11 near the side wall end of the box cover 1 in the opposite direction of the first sink groove 11, so that the first sink groove 11 is separated from the second sink groove 12 to form two groove channels 111. The two groove channels 111 extend close to the side wall of the box cover and penetrate the side wall of the box cover. A vent hole 112 is provided on the bottom surface of the first sink groove 11 away from the side wall of the box cover, and the outer edges of the two groove channels 111 extend inward to form a pin shaft 113.
[0030] like Figure 2 As shown, in order to ensure that the air valve buckle 3 and the box cover body are aligned in the closed state, two limiting columns 115 are symmetrically provided on the side wall of the first sink.
[0031] like Figure 1 、 4 As shown in Figure 5, the box cover 1 is detachably provided with a valve buckle 3, which is a U-shaped structure as a whole. The opening of the U-shaped structure is adapted to the second sink groove 12, and the two parallel protruding ends 31 of the U-shaped structure are respectively located in the two groove channels 111. The bottom surface of the protruding end 31 extends downward to form a hinge block 32, and the hinge block 32 is provided with a card slot 321 which is rotatably connected to the pin shaft 113; a sealing plug is provided on the valve buckle 3 for sealing the vent hole 112.
[0032] The two grooves 111 extend close to the side wall of the box cover and penetrate the side wall of the box cover without damaging the slightly higher outer ring of the top of the box cover 1, and the outer ring remains intact. This not only eliminates the square notch in the prior art, forming a one-piece beautiful appearance, but also simplifies the mold for forming the box cover 1 and reduces investment costs. The use of a slot 321 on the hinge block 32 increases the force strength at the rotation point. At the same time, the upper part of the protruding end 31 abuts the outer ring of the box cover 1 to form a protective structure, which will not cause the problem of falling off due to accidental contact with the buckle. The upper and lower surfaces of the two parallel protruding ends 31 of the U-shaped structure abut against the box cover 1 and the box body 2 respectively. When the air valve buckle 3 rotates, it forms a similar two levers working simultaneously to pry the box cover 1, which is easier and more labor-saving.
[0033] Specifically, the valve buckle 3 is provided with a protrusion 33, on which a valve sealant bean 34 can be detachably mounted. When cleaning or replacing, only the valve sealant bean 34 needs to be removed, making it easy to use and maintain. The valve buckle 3 is an integrally molded structure, and the valve sealant bean 34 is then mounted when in use.
[0034] Specifically, the slot 321 includes a transition slot and a connecting slot, and the connecting slot is a vertical waist-shaped hole. Figure 4 、 5This is more conducive to the smooth cooperation between the pin shaft 113 and the card slot 321, so that the air valve buckle 3 is better connected to the box cover 1 in rotation.
[0035] like Figure 2 、 4 As shown in Figures 5 and 6, a spherical protrusion 322 is provided on the side wall end of the hinge block 32 close to the first sink 11, and a long arc-shaped protrusion 114 is provided at the corresponding position on the side wall of the first sink. The process of closing the air valve buckle 3 and only opening the exhaust hole forms a slight interference that serves as a gear reminder to remind whether the position is in place.
[0036] like Figure 4 As shown, an identification hole 35 is further provided on the upper surface of the air valve buckle 3 , and the position of the identification hole 35 corresponds to the sealing plug, which effectively guides the user to align the sealing plug and quickly insert it into the vent hole 112 .
[0037] like Figure 7 、 8 As shown, a mounting groove 13 is provided at the bottom of the box cover 1. A sealing strip 14 is provided around the mounting groove 13. The sealing strip 14 is pressed against the inner wall of the box body 2 to form a water-tight function, which prolongs the preservation time.
[0038] Specifically, the main body of the box cover 1 is an integrally formed structure, and a sealing strip 14 is mounted thereon when in use.
[0039] like Figure 7 、 9 Figure 11 shows four different states of the fresh-keeping box. Figure 7 The lid 1 of the fresh-keeping box is in a closed state, i.e., a completely sealed state; Figure 9 To put the lid 1 in the exhaust state, slightly open the valve buckle 3 to achieve exhaust. The lid 1 and the valve buckle 3 are made of food-grade materials and can be directly placed in the microwave for heating without removing the lid; Figure 10 When the box cover 1 is in the open state, using the principle of leverage, the air valve buckle 3 is pried open with one hand at the end away from the protruding end 31. The air valve buckle 3 rotates relative to the box cover 1, and the protruding end 31 abuts against the top of the side wall of the box body 2. At the same time, the protruding end 31 abuts against the outer ring of the box cover 1, overcoming the friction between the sealing strip 14 and the inner wall of the box body 2, so that the box cover 1 is easily opened. Figure 10 The box cover 1 is in a completely open state. Figure 10 The further actions are not described here.
[0040] Slightly open the air valve buckle 3 to exhaust, and forcefully open the air valve buckle 3 to open the lid. The operation is simple and one-step, and exhaust and lid opening can be performed with one hand, which is easy to use.
[0041] The above-described embodiments of the present invention do not limit the scope of protection of the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
