[0031] In the description of the present utility model, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present utility model. The following is a detailed description of various embodiments of the present utility model in conjunction with the drawings.

[0032] Example 1

[0033] See also Figures 1 to 9 The utility model preferably provides a technical solution: a bag-packed structure with a new valve body, comprising: a bag body 1, and a mounting piece 211 embedded in the top of the bag body 1; the mounting piece 211 is penetrated with an original feed port 411, which is used to form a first inlet and outlet channel of the bag body 1; and a first valve body feed port 311 arranged on the mounting piece 211, which is used to form a second inlet and outlet channel of the bag body 1, the first valve body feed port 311 penetrates the mounting piece 211 and is connected with the inside of the bag body 1; and the inner wall of the first valve body feed port 311 is formed by connecting the first circular cavity 312 and the second circular cavity 314 at the upper and lower parts; it also includes a valve body structure, the valve body structure includes a first valve core 511, and a first diaphragm 513 arranged in the first valve core 511, and a first opening groove 512 is opened in the middle of the first diaphragm 513; the first valve core 511 is made of elastic rubber material and is elliptical.

[0034] In this application, if Figure 1 , 2 , 3 and 4, a valve body structure as shown in the first valve core 511 is provided, the original feed port 411 is used as the first inlet and outlet channel of the bag body 1, which can be used as the filling port of food or medicine, and can be completely closed after filling, and the first valve body feed port 311 is used as the second inlet and outlet channel of the bag body 1, in order to be flexibly opened and taken, and also needs to have strong airtightness and not easy to fall off, for this reason, the valve body structure is designed;

[0035] Specifically, through the first diaphragm 513 and the first opening groove 512 provided in the middle of the first valve core 511, in combination with its own elastic rubber material and elliptical structure, since the inner wall of the first valve body feed port 311 is connected by the upper and lower first circular cavity 312 and the second circular cavity 314, when the first valve core 511 acts on the inside of the first valve body feed port 311 and moves downward, it is restricted by the shape of the second circular cavity 314. When the first valve core 511 is completely placed in the second circular cavity 314, the elliptical first valve core 511 is restricted by the second circular cavity The circular shape of the body 314 causes the long axis of the first valve core 511 to be compressed and narrowed, thereby squeezing the first opening groove 512 to seal it. Therefore, at this time, the action position of the first valve core 511 can be used to close the channel of the first valve body feed port 311, and when the first valve core 511 is pushed upward, when it is placed on the upper first circular cavity 312, its long axis contacts the inner wall of the first circular cavity 312. At this time, the first opening groove 512 is in a free and relaxed state to be opened, and a straw can be inserted through the channel of the first opening groove 512 to absorb the liquid inside the bag body 1.

[0036] The on-off effect is achieved when the first valve core 511 acts on different positions of the first circular cavity 312 and the second circular cavity 314. The operation is simple and convenient, and the cover body can be opened flexibly for quick and easy access. At the same time, it also has strong airtightness, and the cover body is not easy to fall off. At the same time, a straw can be inserted into the channel position of the first opening groove 512 to further improve its practicality.

[0037] Furthermore, a chamfered transition section 313 is provided at the transition position between the first circular cavity 312 and the second circular cavity 314. Figure 3 , 4 As shown, the arc surface transition section of the chamfered transition section 313 is set to facilitate the bottom of the first valve core 511 to be squeezed and deformed and smoothly enter the second circular cavity 314.

[0038] Furthermore, the diameter of the first circular cavity 312 is not less than the long axis of the first valve core 511. Figure 3 and 4 As shown, the first circular cavity 312 is a circular cavity, and its diameter is greater than or equal to the long axis length of the first valve core 511. Therefore, when the first valve core 511 is placed inside the first valve body feed port 311, it will not be squeezed, that is, the first opening groove 512 is in a free relaxation state to realize the opening of the channel of the first valve body feed port 311.

[0039] Furthermore, the mounting member 211, the first valve body feed port 311 and the original feed port 411 can be integrally injection molded. By integrally injection molding the three, production efficiency can be improved. At the same time, integral molding can reduce connection nodes and further improve the sealing performance of the bag body 1.

[0040] Furthermore, the cross section of the first valve core 511 is an "H" structure, and the cross section of the first opening groove 512 is a "V" structure. The structural strength and sealing performance are further improved by the structural shape setting of the first valve core 511.

[0041] Example 2

[0042] As another embodiment of the present utility model, the valve body structure also includes a second valve body feed port 611 and a second valve core 711. The second valve body feed port 611 passes through the mounting piece 211 and is connected to the bag body 1. The top of the second valve core 711 is connected to an end block 715. The lower surface of the end block 715 can act on the top of the second valve body feed port 611, and a flat cavity 716 passing through the second valve core 711 and the end block 715. A second diaphragm 714 is arranged in the middle of the flat cavity 716, and a second opening groove 712 is arranged in the middle of the second diaphragm 714; the second diaphragm 714, the flat cavity 716 and the second valve core 711 are all arranged in an elliptical shape.

[0043] Furthermore, a limiting slot 612 is provided at the top edge of the second valve body feed port 611 , and the limiting slots 612 are divided into two groups and are arranged opposite to each other. A limiting plug 713 is provided at the top edge of the second valve core 711 , and the limiting plug 713 can be adapted and plugged with the limiting slot 612 .

[0044] Furthermore, two groups of opposite protrusions 7131 are provided on the bottom edge of each limiting plug post 713 , and the second valve core 711 and the protrusions 7131 are both made of elastic rubber material.

[0045] In this embodiment, another valve body structure is provided, such as Figure 5 , 6 As shown in Figures 7, 8 and 9, it consists of a second valve core 711 and an end block 715 at the top, and the end block 715 acts as a top end cover, which is convenient for holding and acting inside the second valve body feed port 611. Compared with Example 1, it does not need to be completely embedded in the first valve body feed port 311, and the process of plugging and unplugging the second valve core 711 is very convenient, which improves the work efficiency of use. At the same time, in conjunction with the limiting groove 612 at the top edge of the second valve body feed port 611, when the second valve core 711 moves downward and acts on the second valve body feed port 611, the limiting plug 713 is inserted into the limiting groove 612, and under the action of two groups of relative protrusions 7131, it realizes elastic limitation with the limiting groove 612, which can further improve the tightness of the second valve core 711 when inserted, and can effectively reduce the probability of falling off, thereby further improving the sealing and safety of the bag body.
