The container body 11 can be used for accommodating a liquid, viscous liquid product such as cosmetics, daily chemicals, medicines, foods, etc., and the container body 11 shown in the drawing is a packaging hose, and has not been subjected to a sealing process state. The vacuum pump head is mounted on the container body 11 to pump the contents of the container body 11.

Specifically, as shown in FIG. 1, the container body 11 includes a body portion 110, a first tube portion 112, a second tube portion 113, a connecting portion 115, and a seal ring 116. The body portion 110 can be used for accommodating liquid, viscous liquid products such as cosmetics, daily chemicals, medicines, foods and the like. The first tube portion 112 and the second tube portion 113 are formed at the same end of the body portion 110, and the second tube portion 113 is located in the first tube portion 112 and communicates with the body portion 110. In the embodiment shown in Figure 1, the first tube portion 112 and the second tube portion 113 are both circular tubes and are disposed substantially coaxially. The connecting portion 115 is formed between the first pipe portion 112 and the second pipe portion 113 and connects the two. The seal ring 116 is formed on the connecting portion 115 and surrounds the second tube portion 113, in other words, the seal ring 116 is disposed to communicate with the body portion 110 around the second tube portion 113. In the embodiment shown in FIG. 1, a seal ring 116 is fixedly formed on the connecting portion 115.

The vacuum pump head includes a push head 121, a pump core 122, and a valve stem 123.

The head 121 includes a pressing portion 1210, a side wall 1211, a support wall 1212, a support column 1213, a chamber 1214, and a liquid outlet hole 1215. Among them, the pressing portion 1210 can be used for a pressing operation to pump the contents of the container body 11. The side wall 1211 is extendable along the circumference of the pressing portion 1210 and at an angle to the pressing portion 1210. The side wall 1211 is slidably disposed in the first tube portion 112 and is in contact with the first tube portion 112. The support wall 1212 is formed on the inner side of the pressing portion 1210 and is located in the side wall 1211 and can be used with the pump core 122 to function to open or close the liquid outlet hole 1215. The support post 1213 is formed inside the pressing portion 1210 and is located in the support wall 1212, and the support post 1213 extends into the second tube portion 113. In the embodiment shown in FIG. 1, the support post 1213 is generally tubular and can be used to mount the valve stem 123. The chamber 1214 is formed in the vacuum pump head 12, and the communication or closing between the chamber 1214 and the body portion 110 is controlled by the positional relationship between the pump core 122, the support column 1213, and the valve stem 123; the chamber 1214 and the liquid outlet The communication or closing between 1215 is controlled by the positional relationship between the pump core 122 and the support wall 1212. By adjusting the positional relationship between the pump core 122, the support column 1213, the valve stem 123, and the positional relationship between the pump core 122 and the support wall 1212, the contents can be sucked from the body portion 110 into the chamber 1214, and then It is discharged from the liquid outlet hole 1215 (to be further explained later). The liquid outlet hole 1215 is mainly used to discharge the contents.

The pump core 122 can be made of a soft rubber material such as TPE, TPU, silicone or rubber. As shown in FIG. 2, the pump core 122 includes a first hollow cylinder 1221, a second hollow cylinder 1223, an extension 1224, a first seal portion 1225, and a second seal portion 1226. The extension portion 1224 is disposed between the first hollow cylinder 1221 and the second hollow cylinder 1223 and connects the two. The first sealing portion 1225 and the second sealing portion 1226 are formed on the first hollow cylinder 1221 and the second hollow cylinder 1223, respectively. As shown in FIG. 1 , the second hollow cylinder 1223 is sleeved on the second pipe portion 113 , and the first hollow cylinder 1221 and the second hollow cylinder 1223 are sandwiched between the first pipe portion 112 and the second pipe portion 113 . between. The first sealing portion 1225 is thinner in thickness and can be engaged with the support wall 1212 to open or close the liquid outlet hole 1215 by its own deformation. The second sealing portion 1226 has a thin wall thickness that can be engaged with the support post 1213 to cause communication or closure between the chamber 1214 and the body portion 110 by its own deformation.

The valve stem 123 includes a rod body 1231, a flange 1235, and a seal groove 1236. The rod body 1231 may be disposed in the support column 1213 and located in the second tube portion 113. A flange 1235 is formed at an inner end of the rod body 1231. A seal groove 1236 is formed on a surface of the flange 1235 adjacent to the joint portion 115 for accommodating the seal ring 116. As shown in FIG. 1, the sealing groove 1236 is in contact with at least one side of the seal ring 116 to form at least one heavy seal. When the body portion 110 is squeezed, the two or multiple seals between the seal groove 1236 and the seal ring 116 will form a self-locking, the greater the external force, the greater the force exerted by the contents of the body portion 110 on the flange 1235, Further, the sealing effect between the sealing groove 1236 and the seal ring 116 is better, thereby preventing the body portion 110 of the packaging container 10 from being squeezed and leaking.

The above is a specific structure of the packaging container 10 in an embodiment of the present invention, and a practical method thereof will be briefly described below.

Figure 3 is a schematic illustration of the vacuum pump head as it is pumped from the packaging container 10. 4 is an enlarged schematic view of the pump core 122 of FIG. As shown in Figures 3 and 4, pressing the vacuum pump head causes the pump core 122 to deform to squeeze the contents of the chamber 1214. Specifically, when the vacuum pump head is pressed, the pressure of the contents in the chamber 1214 is increased, the first seal portion 1225 is pressed, and the second seal portion 1226 is pressed. After the pressure of the contents in the chamber 1214 causes the first sealing portion 1225 to be deformed, as shown in FIG. 3, the contents of the chamber 1214 pass through the gap between the deformed first sealing portion 1225 and the supporting wall 1212. The liquid hole 1215 flows to the outside of the packaging container 10. At the same time, the second sealing portion 1226 is pressed against the support post 1213 under pressure, so that the chamber 1214 and the body portion 110 are closed or not communicated, and therefore, the contents of the chamber 1214 cannot be returned to the body portion 110.

Figure 5 is a schematic illustration of the vacuum pump head as it draws contents into the chamber 1214. Figure 6 is an enlarged schematic view of the pump core 122 of Figure 5. As shown in FIG. 5 and FIG. 6, when the vacuum pump head is loosened, since the pump core 122 is made of an elastic body, the pump core 122 will return to the original shape to achieve a rebounding effect, so that the space in the chamber 1214 gradually becomes larger. The attraction is generated, and the first sealing portion 1225 is brought into close contact with the support wall 1212 to close the liquid outlet hole 1215, and the second sealing portion 1226 is separated from the support column 1213, so that the contents of the body portion 110 flow into the chamber 1214.

In addition, during the transportation, sale, etc., when the body portion 110 of the packaging container 10 is squeezed due to accident or inadvertent operation or the like, at least one heavy seal is formed due to the contact of the sealing groove 1236 with at least one side of the sealing ring 116, and the sealing is performed. The two or multiple seals between the slot 1236 and the seal ring 116 form a self-locking force. The greater the external force, the greater the force exerted by the contents of the body portion 110 on the flange 1235, and thus between the seal groove 1236 and the seal ring 116. The sealing effect is better, thereby preventing the body portion 110 of the packaging container 10 from being squeezed and leaking.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. Within the scope.
