[0050] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0051] like Figure 1-6 As shown, this embodiment of the invention proposes a convenient and practical vacuum food storage container, including a bag body 1 and a vacuum valve 2.

[0052] Specifically, the bag body 1 has a bag opening 3; the vacuum valve 2 is detachably installed at the bag opening 3; and at least one side wall of the bag body 1 has a gas passage 4. The vacuum valve 2 is used to connect to a vacuum pump to achieve vacuum extraction.

[0053] In one embodiment, such as Figure 2 As shown, the bag body 1 is also equipped with a zipper 9. The zipper 9 allows food to be filled without disassembling the vacuum valve 2 simply by opening the zipper 9, making it simple and practical. Preferably, the zipper 9 can be located on one side of the bag body 1, along with the bag opening 3. Alternatively, the zipper 9 can be placed on other sides of the bag body 1 according to actual needs.

[0054] In this embodiment, reference continues to be made to Figure 4 and Figure 5 As shown, the bag body 1 includes a first bag layer 100 and a second bag layer 101. Specifically, a portion of the first bag layer 100 and a portion of the second bag layer 101 are connected; another portion of the first bag layer 100 and another portion of the second bag layer 101 form the bag opening 3; the first bag layer 100 is provided with a first embossed texture 1001, which forms the gas channel 4 when it is attached to the second bag layer 101; at least one side of the first bag layer 100 and the second bag layer 101 is provided with the first embossed texture 1001, and forms the gas channel 4 when it is attached to the other bag layer. The gas channel 4 prevents the formation of air bubbles 1000 inside the bag body 1 during vacuuming. This is because without the gas channel 4, air bubbles 1000 are easily formed (e.g., ...). Figure 1 and Figure 3 As shown, it is impossible to completely vacuum the bag. Or, gas may remain inside the bag, affecting food storage and making it impossible to guarantee the preservation time.

[0055] The actual dimensions of the bag opening 3 and the vacuum valve 2 can be set according to actual needs.

[0056] In one embodiment, reference continues Figure 4 As shown, the surface of the second bag layer 101 is smooth. By making the surface of the second bag layer 101 smooth, it is easy to print the desired patterns and text. Furthermore, even though the surface of the second bag layer 101 is smooth, the first embossing 1001 on the first bag layer 100 has a wavy shape, therefore, as... Figures 1-4 As shown, when the first embossing 1001 comes into contact with the second bag layer 101, it can form the gas channel 4, allowing the gas to be discharged more effectively through the gas channel 4. Even during the vacuuming process, if bubbles 1000 are formed, the bubbles 1000 can also be discharged through the gas channel 4.

[0057] In another embodiment, continue to refer to Figure 5As shown, the second bag layer 101 has a second embossed pattern 1010 symmetrical to the first embossed pattern 1001. The first embossed pattern 1001 and the second embossed pattern 1010 form the gas channel 4. If it is not necessary to print patterns and text on the bag body 1, the second embossed pattern 1010 can form a gas channel 4 when in contact with the first embossed pattern 1001 due to its symmetrical arrangement, and the diameter of the gas channel 4 can be increased, so that the gas can be discharged quickly through the gas channel 4.

[0058] Preferably, both the first embossing 1001 and the second embossing 1010 include dot-like embossing or strip-like embossing. The strip-like embossing is arranged in parallel or interlaced patterns; for example, it can be interlaced diagonal stripes, such as... Figure 1 (dot-like embossing) and Figure 3 As shown in the (strip embossing) diagram, the required process can be adopted according to actual needs. In addition, those skilled in the art will know that, to achieve the same effect, the first embossing 1001 and the second embossing 1010 can also be embossed in other shapes, for example, the first embossing 1001 and the second embossing 1010 can also be raised.

[0059] In this embodiment, the bag body 1 is made of a three-layer composite material of 1.2 filament PET, 1.5 filament PA and 17 filament PE, which makes it more tough and strong.

[0060] In this embodiment, combined with Figure 1 and Figures 6-7 As shown, the bag body 1 includes a bottom, two sides and a top. The two sides are located on the sides of the bottom and the top, respectively, and the bottom and the top are located at the ends of the two sides. The bag opening 3 is located on one side of the two sides, or on the top, or at the connection between the top and the side.

[0061] In this embodiment, a handle 5 is provided on one of the two sides or on the top of the bag to facilitate carrying and emptying the food inside the bag 1.

[0062] For the best options, please continue to refer to them. Figures 1-3 and Figure 6 As shown, the bottom of the bag body 1 is provided with an extension 6, which supports the bag body 1 when unfolded. The extension 6 allows the bag body 1 to stand upright on a table or other surface without external force.

[0063] In a preferred embodiment, when the handle 5 is perpendicular to the extension 6, i.e., when the handle 5 is located on one of the two sides, it is not necessary to support the bottom of the bag when pouring out the food inside the bag body 1. If the handle 5 is located at the top of the bag body 1, i.e., the handle 5 is parallel to the extension 6, the bottom of the bag body 1 needs to be lifted up under gravity to pour out the food (because the width of the extension 6 is greater than the width of the top of the bag body 1, and the area where the extension 6 is located has the most food, making the bottom of the bag heavier). This device, by vertically positioning the handle 5 on the extension 6, eliminates the need to support the bottom of the bag body 1 when pouring out the food, thus facilitating the pouring of food.

[0064] In one specific example, the extension 6 has a fold line in the middle. By folding the extension 6 along the fold line, it is located between the first bag layer 100 and the second bag layer 101, reducing the space occupied by the bag body 1. More specifically, the two sides of the extension 6 are connected to the side wall of the first bag layer 100 away from the bag opening 3 and the side wall of the second bag layer 101 away from the bag opening 3, respectively.

[0065] In one specific embodiment, combined with Figure 1 as well as Figures 6-10 As shown, the bag opening 3 is provided with a hollow connector 7; one end of the hollow connector 7 is connected to the inner wall of the bag body 1 (the connection can be made by welding); the vacuum valve 2 includes a fitting 21, a silicone part 22 and a valve 23.

[0066] Specifically, the fitting 21 is threadedly installed on the hollow connector 7; a sealing ring 24 is provided between the hollow connector 7 and the fitting 21; the end of the fitting 21 away from the hollow connector 7 is provided with multiple through holes 210, mounting holes 211 and an annular member 212; the through holes 210 communicate with the interior of the bag body 1 through the hollow connector 7; the through holes 210 are arranged around the mounting holes 211; the annular member 212 is located in the middle of the fitting 21, and both the through holes 210 and the mounting holes 211 are located in the middle of the annular member 212; the silicone part 22 is installed on the mounting holes 211 and is located inside the annular member 212.

[0067] The annular component 212 has an opening 2120 on its side wall. Specifically, the valve 23 is threaded onto the annular component 212; the side wall of the valve 23 has a slot 230 corresponding to the opening 2120; when the valve 23 is rotated, the vacuum valve 2 exhausts air through the slot 230 corresponding to the opening 2120, or the bag 1 can be sealed by moving away from the opening 2120 through the slot 230.

[0068] In this embodiment, the vacuum valve 2 needs to be used in conjunction with a vacuum pump to achieve vacuum extraction. The vacuum pump can be an electric pump or a manual pump.

[0069] Preferably, the surface of the bag 1 is provided with a volume scale (not shown in the figure for simplicity). The scale unit is milliliters, which allows for easy observation of the amount of food inside the bag 1.

[0070] In addition, this embodiment also includes a folding funnel, which is provided with a snap-fit ​​part; when the vacuum valve 2 is removed, the snap-fit ​​part of the folding funnel snaps into the hollow connector 7, so that food can be poured in.

[0071] In one embodiment, the folding funnel may be made of plastic. For example... Figure 11 As shown, the folding funnel includes: a first connector 80, a second connector 81, and a plurality of third connectors 82. More specifically, the second connector 81 includes four sides; a portion of the first connector 80 is connected to one side of the second connector 81, and the first connector 80 is perpendicular to the second connector 81; the first connector 80 has a plurality of creases 800 perpendicular to the second connector 81, and the remaining portion of the first connector 80 contacts the other three sides of the second connector 81 along the creases 800, forming a rectangular box.

[0072] In this embodiment, the second connector 81 has a connecting hole 810 in the middle. When the vacuum valve 2 is removed, the hollow connector 7 passes through the connecting hole 810 and is snapped in place. The edge of the connecting hole 810 also has multiple symmetrical notches 811 to facilitate the smooth passage of the hollow connector 7 through the connecting hole 810.

[0073] In one embodiment, a plurality of third connectors 82 are respectively connected to the other three sides of the second connector 81; a locking member 820 is provided on the side of the third connector 82 away from the second connector 81, and the first connector 80 is provided with a slot 801 for locking the locking member 820; when the third connector 82 is folded upward along the connection between the third connector 82 and the second connector 81 (upward means: the locking member 820 moves closer to the slot 801), the locking member 820 can be inserted into the slot 801.

[0074] In a specific example, continue to refer to Figure 11As shown, the first connector 80 has three creases 800, which divide the first connector 80 into a first device 802, a second device 803, a third device 804, and a fourth device 805. The second device 803 is located between the first device 802 and the third device 804, and the third device 804 is located between the second device 803 and the fourth device 805.

[0075] In this configuration, one side of the second device 803 is connected to one side of the second connector 81. The first device 802, the third device 804, and the fourth device 805 are folded around the second connector 81 along three creases 800, forming the rectangular box with the second connector 81. One side of the first device 802, the third device 804, and the fourth device 805 is in contact with the other three sides of the second connector 81.

[0076] Preferred, such as Figure 12 As shown, the first device 802, the third device 804 and the fourth device 805 are all provided with the slot 801; when the third connector 82 is folded upward along the connection between the third connector 82 and the second connector 81, the card 820 can be inserted into the slot 801.

[0077] In another embodiment, such as Figure 13-14 As shown, the folding funnel is made of silicone material; the folding funnel includes an integrally molded connector 83 and a telescopic component.

[0078] Specifically, the connector 83 has a hollow structure and is used to fit the hollow connector 7 for a snap-fit ​​operation; the outer wall of the connector 83 is provided with multiple reinforcing ribs 830; the telescopic member has a hollow structure and is connected to the connector 83.

[0079] In this embodiment, the telescopic component includes a first telescopic layer 840, a second telescopic layer 841, and a third telescopic layer 842; the second telescopic layer 841 is located between the first telescopic layer 840 and the third telescopic layer 842; one end of the third telescopic layer 842 away from the second telescopic layer 841 is connected to the connector 83; the diameter of the second telescopic layer 841 is smaller than the diameter of the first telescopic layer 840 and larger than the diameter of the third telescopic layer 842; the connector 83, the third telescopic layer 842, and the second telescopic layer 841 are folded sequentially in the direction toward the first telescopic layer 840 (to achieve the folding of the folding funnel); or, the connector 83, the third telescopic layer 842, and the second telescopic layer 841 are stretched sequentially in the direction away from the first telescopic layer 840 to form a funnel-shaped structure.

[0080] Preferably, the side wall of the first telescopic layer 840 is provided with a handle 85, and the handle 85 is provided with a hanging hole 850, which can be used to hang the folding funnel on a hook.

[0081] In this embodiment, the manufacturing process can be carried out in the following order: plate making, printing film, composite three-layer film, embossing one side of the bag body 1 (one side of the bag body 1 refers to the first bag layer 100 or the second bag layer 101), bag making, hot-pressing the suction nozzle, and attaching the handle 5.

[0082] Furthermore, this embodiment also proposes a method for using a vacuum food storage container, which specifically includes the following steps:

[0083] S1. Remove the vacuum valve 2 from the vacuum food storage container, snap the folded funnel into the hollow connector 7, and pour the food in.

[0084] S2. After the food is filled, install the vacuum valve 2 on the hollow connector 7 and connect the vacuum pump to the hollow connector 7 to perform a vacuuming operation.

[0085] S3. After vacuuming is complete, rotate valve 23 of vacuum valve 2 to seal the entire bag body 1.

[0086] In this embodiment, the vacuum pump is installed with the vacuum pump by rotating the valve 23 of the rotary vacuum valve 2, for example, by rotating the valve 23 clockwise, and the vacuuming operation begins. After the vacuuming is completed, the valve 23 is rotated counterclockwise to seal the entire bag 1.

[0087] In summary, the vacuum food storage container and its usage method proposed in this invention have the following advantages:

[0088] This device utilizes a bag body and a vacuum valve; the bag body has an opening; the vacuum valve is detachably mounted at the opening; and at least one side wall of the bag body has a gas passage. By connecting a vacuum pump to the vacuum valve, this device can vacuum-preserve food. Furthermore, during the vacuuming process, the two side walls of the bag can easily adhere together, causing air bubbles to form at the bottom of the bag, preventing the complete removal of gas from the bag. This device, with its gas passage, avoids this problem, allowing the gas to be completely released through the gas passage, thus improving the preservation time.

[0089] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
