detailed description

As shown in Fig. 1 and Fig. 2, it is the overall structure schematic diagram of the present utility model, and this container can be the rectangular container as shown in Fig. 1, also can be the circular container as shown in Fig. 2, and this container comprises lid 100 With the box body 200, the box cover 100 and the box body 200 cover each other to form a sealed cavity.

Specifically, the box cover 100 has a cover top 110, the center of which is a substantially flat plane, and an annular groove 130 is arranged on the central plane. The cover side 120 extends downward from the periphery of the cover top 110 , and extends horizontally outward from the cover side 120 to form the cover outer edge 103 . A lid sealing edge protrudes outward from the lid outer edge 103 , and the lid sealing edge includes an upwardly curved section 1001 , a transition section 1002 and a downwardly curved section 1003 . Wherein, the upper curved section 1001 is an annular shape bent upwards and connected with the outer edge 103 of the cover, and the upper curved section 1001 of the side surface 120 of the cover, the outer edge 103 of the cover and the sealing edge of the cover forms a V-shaped structure in cross section. The transition section 1002 is a substantially flat ring shape, and the downward bending section 1003 is a downwardly bent ring shape. The two arc sides of the transition section 1002 are respectively connected to the upper bend section 1001 and the lower bend section 1003, and the upper bend section 1001, the transition section 1002 and the lower bend section 1003 of the sealing edge of the cover form an inverted U-shaped structure in cross section.

Wherein, the sides corresponding to the upper curved section 1001 and the lower curved section 1003 are respectively the inner surface of the upper curved section 1001 and the inner surface of the lower curved section 1003, and the surface of the transition section 1002 connected to the inner surface of the lower curved section 1003 is the transition The lower surface of the section 1002 and the surface of the outer edge 103 of the cover connected to the inner surface of the upwardly curved section 1001 is the lower surface of the outer edge 103 of the cover.

A barb 1004 protruding from the sealing edge of the lid is provided at the inner side of the bent down section 1003 . A first sealing flange 1005 is disposed on the lower surface of the transition section 1002 , and the first sealing flange 1005 is concentric with the transition section 1002 . The lower surface of the cover outer edge 103 is provided with a second sealing flange 1006 , and the second sealing flange 1006 is concentric with the cover outer edge 103 .

The box body 200 has a box bottom 210. The center of the box bottom is a substantially flat plane, and an annular rib 230 is arranged on the center plane. The annular rib 230 serves as a foot for the box body to support the box body on the desktop. The box side 220 is extended upward from the outer periphery of the box, and the box outer edge 203 is formed horizontally and outwardly from the box side 220 . The box sealing edge extends outward from the box outer edge 203 , and the box sealing edge includes an upper extension 2001 , a connecting section 2002 and a lower extension 2003 . Wherein, the upper extension 2001 is an upwardly bent ring connected to the outer edge 203 of the box, and the upper extension 2001 of the side 220 of the box, the outer edge 203 of the box and the sealing edge of the box forms a V-shaped structure in cross section. The connecting section 2002 is substantially flat and annular, and the descending section 2003 is downwardly bent annular. The two arc edges of the connection section 2002 are respectively connected to the upper extension section 2001 and the lower extension section 2003, and the upper extension section 2001, the connection section 2002 and the lower extension section 2003 of the sealing edge of the box form an inverted U-shaped structure in cross-sectional view.

As shown in Figure 4, the lid sealing edge and the box sealing edge are formed into shapes that cooperate with each other. When the lid is closed, the downward bending section 1003 of the lid sealing edge and the lower extending section 2003 of the box sealing edge fit together, and the sealing edge of the lid The barb 1004 engages and holds up the sealing edge of the box so that the sealing edge of the box is close to the sealing edge of the lid. The first sealing flange 1005 presses against the connecting section 2002 of the sealing edge of the box, thereby forming a first sealing edge. The second sealing flange 1006 presses against the outer edge 203 of the box to form a second sealing edge.

Moreover, there is a bend between the barb 1004 and the first sealing flange 1005 on the sealing edge of the box. When the lid is closed, there is a gap between the box lid 100 and the box body 200 at this bent position, forming a first airtight air bubble chamber 301 . And there are two bends between the first sealing flange 1005 and the second sealing flange 1006. When the lid is closed, the lid 100 and the box body 200 leave a gap at these two bends to form a second seal. bubble chamber 303 and a third sealed bubble chamber 305 .

The traditional airtight container is sealed by a rubber seal ring with a large width, which has a significant effect on blocking the leakage of solid particles or the entry of air. However, the blocking effect on liquids is poor, and generally cannot prevent such as vegetable juice, soup, etc. Class extravasation. However, the utility model adopts the sealing flange, the width of the flange is small, and the box cover and the box body are clamped with each other through the barb, so that a large pressure is obtained when the top is pressed, and the sealing effect is remarkable, even if it is a liquid content, It also prevents extravasation. Furthermore, the utility model adopts two sealing flanges to form the first sealing edge and the second sealing edge, and establishes two lines of defense to well isolate the contents of the sealed container of the utility model from the outside world.

Further, the annular groove 130 of the cover top 110 and the annular rib 230 of the box bottom 210 have coincident projection positions and are shaped to match each other. When the box body 200 is placed on the top of the box cover 100, the annular rib 230 embedded in the ring groove 130 . Such a structure enables the box cover 100 to be stably placed under the box body 200 after opening, reducing the occupied space.

As can also be seen in FIG. 3 , the cover side 120 extends downward from the cover top 110 at a substantially vertical or outwardly expanding angle, so that a plurality of box covers 100 can be stacked up and down. The box side 220 is formed to extend upward from the box bottom 210 at a substantially vertical or outwardly expanding angle, so that a plurality of boxes 200 can be stacked up and down. After the lid 100 and the box body 200 are assembled as shown in Figure 3, a plurality of lids 100 can be stacked on top of the lid 100, and a plurality of box bodies 200 can be stacked on the bottom of the box body 200, so that The display space can be reduced during sales or home storage.

The box side 220 of the box body 200 gradually extends upward from the box bottom 210 and forms two stepped surfaces. The box body is not easily deformed by external force.

The box body 200 and the box cover 100 are made of plastic or rubber material, so that the box body 200 and the box cover 100 have certain plasticity.

The utility model is not limited to the above-mentioned embodiment, if the various changes or modifications of the utility model do not depart from the spirit and scope of the utility model, if these changes and modifications belong to the claims of the utility model and within the equivalent technical scope, Then the utility model is also intended to include these modifications and variations.
