[0018] The utility model provides a flexible cap and a packaging bottle containing the same. Compared with the prior art, the utility model has the following beneficial effects:

[0019] When the utility model of the swing cover is used, when the liquid in the container needs to be used, the container is squeezed to increase the pressure in the container, and the pressure in the container generates an opening pressure on the seal, and the opening pressure is directed toward the end away from the container. Under the action of the opening pressure, the seal moves in the first channel toward the end away from the container. Based on the direction from the inlet end to the outlet end of the first channel, the internal flow area of ​​the first channel gradually increases and then gradually decreases. Therefore, as the seal moves, the seal enters the middle area of ​​the first channel, and a liquid flow gap is formed between the seal and the first channel. At the same time, under the action of the opening pressure, the liquid in the container is squeezed out of the container and flows through the liquid flow gap and then flows out of the first channel for use by consumers; when someone maliciously injects liquid of other substances into the container from the outside, the pressure of the externally injected liquid will push the seal to move in the first channel toward the end close to the container until the seal is matched with the opening of the end of the first channel close to the container. Since the outer contour of the seal is matched with the inner contours of the two ends of the first channel, the seal will fit together with the end of the first channel close to the container to form a seamless match, thereby preventing the injection of other liquids.

DETAILED DESCRIPTION

[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] On the one hand, if Figure 1 As shown, a flexible cover 100 is used for sealing a container, the container 200 can be squeezed, and the flexible cover 100 includes a cover body 110, which is arranged at the open end of the container 200;

[0033] Among them, the cover body 110 is provided with a first channel 111, and the first channel 111 penetrates the cover body 110 in a direction parallel to the cover body 110 toward the container 200, and along the direction from the inlet end to the outlet end of the first channel 111, the internal flow area of ​​the first channel 111 gradually increases and then gradually decreases. A sealing member 310 is movably arranged in the first channel 111, and the outer contour of the sealing member 310 is conformed to the inner contours of the two ends of the first channel 111.

[0034] When the swing cover 100 of the utility model is used, when the liquid in the container 200 needs to be used, the container 200 is squeezed to increase the pressure in the container 200. The pressure in the container 200 generates an opening pressure on the seal 310, and the opening pressure is toward the end away from the container 200. Under the action of the opening pressure, the seal 310 moves in the first channel 111 toward the end away from the container 200. Based on the direction from the inlet end to the outlet end of the first channel 111, the internal flow area of ​​the first channel 111 gradually increases and then gradually decreases. Therefore, as the seal 310 moves, the seal 310 enters the middle area of ​​the first channel 111, and a liquid flow gap is formed between the seal 310 and the first channel 111. At the same time, under the action of the opening pressure, the liquid in the container 200 is squeezed out of the container 200 and flows through the liquid flow gap and then flows out of the first channel 111 for use by consumers; when someone maliciously injects liquid of other substances into the container 200 from the outside, the pressure of the externally injected liquid will push the seal 310 to move in the first channel 111 toward the end close to the container 200 until the seal 310 is matched with the opening of the end of the first channel 111 close to the container 200. Since the outer contour of the seal 200 is conformed with the inner contours of the two ends of the first channel 111, the seal 310 will fit together with the end of the first channel 111 close to the container 200 to form a seamless fit, thereby preventing the injection of other liquids.

[0035] In some embodiments of the present invention, the Qianqiu cover 100 further includes a top cover 120 mounted on the cover body 110, the cover body 110 is provided with a partition 112, the top cover 120 is provided with a second channel 121, and the top cover 120 has an open state and a closed state, such as Figure 1-2 As shown, when the top cover 120 is in the open state, the second channel 121 can communicate with the first channel 111, as shown in FIG. Figure 4-5 As shown, when the top cover 120 is in a closed state, the second channel 121 is disconnected from the first channel 111 by the partition 112 .

[0036] like Figure 2 , Figure 5As shown, the utility model of the swing cover 100 is provided with a first channel 111 in the cover body 110 and a sealing member 310 is placed inside the first channel 111, and a second channel 121 is provided in the top cover 120. When the top cover 120 is in a closed state, the first channel 111 and the second channel 121 are disconnected by the partition 112; when the top cover 120 is in an open state, the first channel 111 and the second channel 121 can be connected. Specifically, the sealing member 310 is located in the first channel 111 close to the container 200 under the action of its own gravity. , so that the first channel 111 is in a sealed state, and under the action of the pressure difference between the inside and outside of the container, liquid can be prevented from entering the container 200 from the outside, and foreign substances can be prevented from entering the container 200 through the first channel 111, thereby ensuring that the internal environment of the container 200 is not polluted; when in use, the container 200 is squeezed, and the sealing member 310 moves to the end of the first channel 111 close to the top cover 120 under the action of the squeezing force, and the liquid in the container 200 can flow out normally after passing through the first channel 111 and the second channel 121.

[0037] In some embodiments of the present invention, Figure 2 , Figure 5 As shown, the cross section of the seal 310 is the same as the cross section of the first channel 111 , and the cross section of the first channel 111 gradually decreases from both ends to the middle, so that the seal 310 can achieve a better sealing effect with the first channel 111 .

[0038] Optionally, the cross-section of the seal 310 and the cross-section of the first channel 111 are both circular. Preferably, the seal 310 is a sphere so that the seal 310 can better seal with the first channel 111 under its own gravity to prevent external substances from entering the container 200.

[0039] It can be understood that when the container 200 is placed normally, the seal 310 is located at the bottom of the first channel 111 under its own gravity, and the diameters at both ends of the first channel 111 are smaller than the maximum diameter of the seal 310. Thus, the seal 310 can achieve sealed contact with both ends of the first channel 111; and in order to allow the substance in the container 200 to flow out through the first channel 111 and the second channel 121, the seal 310 and the middle part of the first channel 111 are matched with a gap greater than zero, and the liquid in the container 200 can flow out by squeezing the container 200.

[0040] In some embodiments of the present invention, Figure 2 , Figure 5 As shown, a stopper 320 is also included. The stopper 320 is connected to one end of the sealing member 310 close to the top cover 120 . The stopper 320 can pass through the outlet end of the first channel 111 and abut against the top cover 120 .

[0041] It is understandable that when squeezing the container 200 to allow the liquid to flow out, there is a situation where the seal 310 is stuck in the first channel 111 at one end close to the top cover 120 and cannot be reset. Therefore, a limit member 320 is added. When the above situation occurs, by closing the top cover 120, a force is applied to the seal 310 in the direction of the container through the limit member 320, so that the seal 310 moves until the seal 310 is located entirely inside the first channel 111.

[0042] In some embodiments of the present invention, Figure 2 , Figure 5 As shown, the partition 112 is arranged around the outer side of the first channel 111 and forms a third channel 113. When the top cover 120 is in the open state, the first channel 111 and the second channel 121 are connected through the third channel 113; the inner side of the top cover 120 is provided with a mounting groove 122, and the partition 112 extends from the opening end of the container 200 to the direction of the top cover 120 and can abut against the mounting groove 122 to disconnect the first channel 111 and the second channel 121.

[0043] like Figure 2 As shown, by pressing the top cover 120, the top cover 120 is in an open state, at which time the first channel 111 and the second channel 121 are connected through the third channel 113, and by pressing the top cover 120, the top cover 120 is in a closed state, as shown in FIG. Figure 5 As shown, the installation groove 122 cooperates with the partition 112 so that the partition 112 is exactly located in the installation groove 122 , so that the second channel 121 is disconnected from the first channel 111 and the third channel 113 .

[0044] In some embodiments of the present invention, Figure 2 , Figure 5 As shown, a reinforcing rib 114 is provided at one end of the cover body 110 close to the top cover 120 . When the top cover 120 is in an open state, one side of the top cover 120 can abut against the reinforcing rib 114 to increase the strength of the joint surface between the top cover 120 and the cover body 110 .

[0045] Optionally, the top cover 120 is provided with a buffer portion 123, and the end of the cover body 110 close to the top cover 120 is provided with a support portion 115 slidably connected to the buffer portion 123, and the support portion 115 is located between the partition 112 and the reinforcing rib 114; preferably, the buffer portion 123 has a first curved surface, and the support portion 115 has a second curved surface, and the first curved surface and the second curved surface are adapted to each other. Specifically, one of the first curved surface and the second curved surface is a concave curved surface and the other is a convex curved surface. When the top cover 120 is opened or closed by a pressing operation, the relative movement of the curved surfaces can make the pressing operation smoother and more flexible.

[0046] On the other hand, an embodiment of the utility model further provides a packaging bottle, comprising a container 200 and a swing cap 100 according to any one of the above embodiments.

[0047] Alternatively, if Figure 2 , Figure 3 , Figure 5 As shown, an end of the container 200 near the top is provided with an external thread 210 and a plurality of buckles 220, and the buckle 200 is located at the bottom of the external thread 210; the hinged cover 100 is provided with an internal thread and a plurality of grooves, the internal thread cooperates with the external thread 210, the buckle 220 cooperates with the groove, and along the tightening direction of the internal thread and the external thread 210, the protruding height of the first end of the buckle 220 to the second end of the buckle 220 relative to the outer circumferential surface of the container 200 gradually increases, thereby realizing a locking connection between the hinged cover 100 and the container 200.

[0048] It can be understood that the packaging bottle of the present invention adopts two structures, namely, thread and buckle, to realize the connection between the swing cover 100 and the container 200, and the directions of the thread and the buckle are opposite, so that the swing cover 100 and the container 200 are completely locked, which can ensure that the packaging bottle cannot be opened after use to prevent secondary use.

[0049] To sum up, the packaging bottle of the utility model, on the one hand, improves the swing cover itself, which can prevent external substances from entering the container and ensure that the internal environment of the container is not polluted; on the other hand, the connection relationship between the swing cover and the container is improved, so that the swing cover and the container are completely locked and cannot be opened under the action of external force, preventing the packaging bottle from being used a second time.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
