[0002] Vacuum extrusion bottles, also known as vacuum bottles, are special containers characterized by their ability to create and maintain a vacuum state within the bottle. Their unique structure and performance have led to their wide application in various fields. With continuous technological advancements and people's pursuit of a higher quality of life, the application areas of vacuum extrusion bottles will continue to expand and be optimized.

[0003] Currently, there are many shapes of vacuum extrusion containers on the market. Traditional vacuum extrusion containers usually have their air inlet valves installed on the side of the bottle body or the side of the bottle mouth. When installing the air inlet valve, it is necessary to first drill a hole on the side of the bottle body or the side of the bottle mouth, then press a connector into the hole, and then install the air inlet valve onto the connector, so that the air inlet valve fits perfectly with the hole.

[0004] The above method is cumbersome due to drilling, and the manufacturing and assembly are difficult, resulting in high production costs for this type of vacuum extrusion container. In addition, since the air inlet valve is installed on the side wall of the bottle body or the side wall of the bottle mouth by drilling, it occupies space in the vacuum extrusion container.

The soft one-way air inlet valve 7 is installed on the air inlet valve seat 6. An air inlet is opened at the bottom of the bottle body 1 (specifically, the bottom of the bottle body 1 has a concave bottom structure 5, and an air inlet is opened on the concave bottom structure). An air inlet channel is opened on the air inlet valve seat 6. The air inlet channel and the air inlet are separated by the soft one-way air inlet valve 7.

[0042] A bottle cap 2 is installed at the mouth of the bottle body 1. The bottle cap 2 includes a bottle cap body 21 and a bottle cap fastening part 22. The bottle cap body 21 and the bottle cap fastening part 22 are connected by a hinge. A liquid outlet 213 is provided on the bottle cap body 21 and is connected to the liquid outlet channel. The bottle cap fastening part 22 has an inner plug sealing part 221 corresponding to the liquid outlet 213. When the bottle cap fastening part 22 is fastened on the bottle cap body 21, the inner plug sealing part 221 seals and plugs the liquid outlet 213.

[0043] The bottle cap 2 has an outer skirt 211 and an inner skirt 212 along the direction from the bottle mouth to the bottle bottom. The inner skirt 212 is located outside the outer skirt 211 and extends into the inside of the bag body 10, while the outer skirt 211 extends into the outside of the bottle body 1. Specifically, the bottle cap body 21 has an outer skirt 211 and an inner skirt 212 along the direction from the bottle mouth to the bottle bottom. The inner skirt 212 is located outside the outer skirt 211 and extends into the inside of the bag body 10, while the outer skirt 211 extends into the outside of the bottle body 1. A liquid outlet valve seat 4 is fastened to the inner skirt 212. Specifically, a liquid outlet valve seat 4 is fastened to the inner skirt 212. It is also made of soft, one-way material. The dispensing valve 3 is installed on the dispensing valve seat 4 along the direction from the bottle mouth to the bottom of the bottle. The dispensing valve seat 4 is provided with a dispensing channel, which is connected to the dispensing nozzle 213 on the bottle cap 2. Specifically, the dispensing channel is connected to the dispensing nozzle 213 on the bottle cap body 21. The dispensing channel is blocked from the inside of the bag body 10 by a soft one-way dispensing valve 3. Specifically, the bottle cap 2 is fastened to the bottle mouth of the bottle body 1. More specifically, the outer skirt 211 has a bottle cap outer fastening part 2111, and the bottle mouth of the bottle body 1 also has a bottle mouth fastening part 101. The bottle cap outer fastening part 2111 and the bottle mouth fastening part 101 are fastened together to fix the bottle cap 2 to the bottle body 1.

[0044] The inner skirt 212 has an inner cap fastening part 2121, and the outlet valve seat 4 has an outlet valve seat first fastening part 41. The inner cap fastening part 2121 and the outlet valve seat first fastening part 41 are fastened together to fix the outlet valve seat 4 to the bottle cap 2.

[0045] Both the flexible one-way air inlet valve 7 and the flexible one-way liquid outlet valve 3 have umbrella-shaped structures, serving as the flexible one-way air inlet valve umbrella structure 71 and the flexible one-way liquid outlet valve umbrella structure 31, respectively. The flexible one-way air inlet valve umbrella structure 71 contacts the air inlet valve seat 6 and blocks the air inlet passage. Specifically, the air inlet valve seat 6 has a planar structure, and the air inlet passage is opened on this planar structure. The flexible one-way air inlet valve umbrella structure 7 on the air inlet valve 7 is laid flat on this planar structure to block the air inlet passage. More specifically, this planar structure is a countersunk hole 8, and the countersunk hole 8 has a plane that matches the flexible one-way air inlet valve umbrella structure 7. The flexible one-way liquid outlet valve umbrella structure 31 contacts the liquid outlet valve seat 4 and blocks the liquid outlet passage.

[0046] The soft one-way intake valve 7 has a soft one-way intake valve fastening part 72, and the intake valve seat 6 has an intake valve seat first fastening part 61, which is fastened to the soft one-way intake valve fastening part 71; the soft one-way liquid outlet valve 3 has a soft one-way liquid outlet valve fastening part 32, and the liquid outlet valve seat 4 has a liquid outlet valve seat second fastening part 42, which is fastened to the soft one-way liquid outlet valve fastening part 32.

[0047] In this embodiment, air intake and liquid output are performed in the following manner:

[0048] First, open the bottle cap 2, then open the bottle cap fastening part 22, so that the inner stopper sealing part 221 is separated from the liquid outlet 213. Then, when the bottle body 1 of the bag in the bottle is squeezed, the internal pressure of the bottle body 1 increases, and the liquid in the bag body 10 pushes open the soft liquid outlet one-way valve 3, so that the umbrella structure 31 of the soft one-way liquid outlet valve is separated from the liquid outlet valve seat 4, thereby connecting the inside of the bag body 10, the liquid outlet channel and the liquid outlet 213. Then, the contents of the soft liquid outlet one-way valve are squeezed out by the pressure between the bottle body 1 and the bag body 10 through the liquid outlet channel and the liquid outlet 213.

[0049] When the pressure on bottle 1 is released, the internal pressure of bottle 1 decreases, and bottle 1 returns to its original shape, while bag 10 remains in a collapsed state. The outlet nozzle 213 and outlet channel are connected sequentially. Given that the second engaging part 42 of the outlet valve seat is engaged with the engaging part 32 of the soft one-way outlet valve (i.e., the soft one-way outlet valve 3 is not separated from the outlet valve seat 4), under external pressure, the soft one-way outlet valve 3 closes. The umbrella-shaped structure 31 of the soft one-way outlet valve contacts the surface of the outlet valve seat 4, blocking the air inlet channel. At this point, the outlet channel and outlet nozzle 213 are blocked by the soft one-way outlet valve. When the valve 3 is blocked, a negative pressure is formed between the bottle body 1 and the bag body 10. Then, the bottle cap fastening part 22 is closed, so that the inner plug sealing part 221 seals and plugs the liquid outlet 213. At this time, the air entering the bottle body from the outside will push open the soft one-way air inlet valve 7, that is, the soft one-way air inlet valve 7 located at the bottom of the bottle is opened. Even if the soft one-way air inlet valve umbrella structure 71 is separated from the air inlet valve seat 6, the air inlet valve seat guide hole 9, air inlet channel, opening and the inside of the bottle body 1 are connected. Air enters the bag body 10 and the bottle body 1 through the air inlet valve seat 9, air inlet channel, opening and the inside of the bottle body 1 to form a pressure balance.

[0050] Example 2

[0051] This embodiment is basically the same as embodiment 1, except that the air inlet valve seat 6 and the bottom of the bottle body 1 are laser welded in this embodiment.

[0052] The air intake and liquid outlet methods in this embodiment are the same as those in Embodiment 1, and will not be described in detail here.

[0053] Example 3

[0054] This embodiment is basically the same as embodiment 1, except that in this embodiment, the air inlet valve seat 6 is fastened to the bottom of the bottle body 1.

[0055] The air intake and liquid outlet methods in this embodiment are the same as those in Embodiment 1, and will not be described in detail here.

[0056] Specifically, such as Figure 13-14As shown: The edge of the air intake valve seat 6 has a second fastening part 62, and the bottom of the bottle body 1 has a bottom fastening part 102 that cooperates with the second fastening part 62. The bottom fastening part 102 is located on the side wall of the concave bottom structure 5. In addition, the air intake valve seat 6 also has an air intake valve seat positioning ring 63 in the vertical direction. When the second fastening part 62 of the air intake valve seat is fastened to the bottom fastening part 102, the top of the positioning ring 63 of the air intake valve seat abuts against the top of the concave bottom structure 5, and the bottom end of the air intake valve seat 6 is located inside the concave bottom structure 5. That is, when the bottom of the bottle body 1 supports an external object, the bottom surface of the air intake valve seat 6 is suspended from the ground. For example, when the bottle body 1 is placed on the ground, the bottom of the bottle is in contact with the ground, but the bottom surface of the air intake valve seat 6 is not in contact with the ground.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
