DETAILED DESCRIPTION

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] like Figure 1-3 A sealed packaging bag shown in the figure comprises a bag body 1, on which a liquid cavity 7, a main opening 11 connecting the liquid cavity 7 with the outside, and an air opening are provided. A tearing opening 4 is also provided on the edge of the bag body 1 on one side close to the main opening 11, a sealing assembly 2 is provided at the main opening 11, and the air opening comprises two groups of main openings 12 located on one side close to the main opening 11 and a bottom opening 13 on the other side relatively far from the main opening 11. A telescopic straw 14 is also provided in the main opening 12, and sealing members 15 are provided on the outside of the main opening 12 and the bottom opening 13, and the diameter of the end of the telescopic straw 14 exposed from the main opening 12 is smaller than the inner cavity of the sealing member 15.

[0018] As a further configuration of the above solution, the sealing assembly 2 and the sealing member 15 are both connected to the bag body 1 by threaded sealing and fixing to seal the liquid cavity 7 of the bag body 1 .

[0019] As a further configuration of the above scheme, the main mouth 12 is tilted relative to the bag body 1, the size of the telescopic straw 14 extending into the liquid cavity 7 is matched with the size of the liquid cavity 7, and the front end of the telescopic straw 14 abuts against the bottom of the liquid cavity 7 on the other side.

[0020] As a further configuration of the above solution, a constricted step 122 with an inclined surface 121 is provided at the front opening 12 , and a frustum ring edge 141 matching the constricted step 122 is provided on the telescopic suction tube 14 .

[0021] As a further configuration of the above solution, a hanging opening 8 is further provided on the bag body 1 , and the hanging opening 8 is provided on a side of the bag body 1 relatively far away from the main opening 11 .

[0022] Example 1: Figure 1The sealing bag of the present embodiment shown includes a bag body 1 with a liquid cavity 7. The liquid cavity 7 is provided with three openings for connecting to the outside, including a main opening 11, a front opening 12 and a bottom opening 13. The main opening 11 is used for the main liquid injection and liquid discharge, while the front opening 12 and the bottom opening 13 are mainly used for corresponding opening for exhaust or intake when the main opening 11 is in effect. In addition, a telescopic straw 14 is provided in the front opening 12 for special groups of people, such as people with injured lips who are not suitable to open their lips or small children who are not convenient to use the main opening 11 directly. In addition, when the bag body 1 is heated, the front opening 12 can also be opened to pull out the telescopic straw 14 therein, such as Figure 2 As shown, the pulled-out telescopic straw 14 can be used as an air inlet of the liquid chamber 7 to prevent the bag body 1 from thermally expanding during heating and causing sealing problems of the bag body 1 .

[0023] As described above, the telescopic straw 14 of the present embodiment includes a tube body and a frustum ring edge 141 extending from the tube body. When the telescopic straw 14 is inserted into the bag body 1, the tapered side of the frustum ring edge 141 cooperates with the inclined surface 121 of the necking step 122 to allow it to extend into the bag body 1. When the telescopic straw 14 is inserted into the bag body 1, the right-angle side end abuts against the plane of the necking step 122, thereby preventing the telescopic straw 14 from easily falling out.

[0024] When injecting liquid, the user can open the main opening 12 and pull the telescopic straw 14 to the highest side. At this time, when injecting liquid into the main opening 11, the telescopic straw 14 is located at the uppermost end for exhaust, thereby preventing the internal air from being discharged from the main opening 11 and causing difficulty in injecting liquid. When discharging liquid, the bag body 1 can be inverted, the main opening 11 can be opened first, and then the bag body 1 can be inverted. After inversion, the seal 15 of the bottom opening 13 can be unscrewed to release the seal, thereby preventing bottom drainage. The liquid cavity 7 of the inverted bag body 1 can shrink due to air pressure, resulting in incomplete drainage. The main opening 11 and the bottom opening 13 can also be opened again after inversion to pour liquid.

[0025] In addition, a tearing hole 4 is also provided on the side of the bag body 1 of this embodiment. After pouring out the liquid, if some liquid remains in the bag body 1 and cannot be poured out or there is no need to pour out the liquid directly through the tearing hole 4, the bag body 1 can be sealed and the liquid inside can be quickly and completely poured out.

[0026] As described in 1-3 above, the sealed packaging bag of the utility model comprises a bag body having a main opening with a larger opening and two sets of opposite air openings and liquid cavities. When injecting liquid, the main opening side can be opened to exhaust gas synchronously to facilitate the injection of liquid. When pouring liquid from the main opening, the air opening on the other side is opened to break the seal to facilitate pouring out. In addition, a telescopic straw is provided to facilitate special personnel to drink medicine and can be pulled out when heated to avoid the problem of bag bulging due to the increase in temperature of the liquid in the bag. A tearing opening is also provided, which can be used to directly tear open the bag body to pour out the liquid or to pour out the residual liquid in the bag. It can adapt to the types of liquid seals.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
