Description

A self-sealing straw cap

technical field

The invention relates to a beverage packaging container, in particular to a straw cover with an automatic sealing function.

Background technique

In the prior art, the container lid installed on the container opening has only a single function of opening and covering. For example, the lid on the beverage container is screwed on the container mouth in a screw-in manner. When opened, if the container If the drink is not finished and the drink in the container needs to be taken away, the cover must be re-screwed by hand. If the cover is not closed, the drink in the drink container will be easily contaminated. When the container body is overturned, the liquid in the container will Leakage. In addition, in order to prevent the liquid in the container from flowing out of the container mouth automatically when the container is under pressure, it is usually necessary to increase the thickness of the container body so that the container body has a certain strength. Doing so will increase the consumption of plastic raw materials , increase the product cost, moreover, the product with certain thickness cannot be folded or compressed, will take up a large amount of space.

Detailed ways

Referring to Fig. 1 to Fig. 12, a self-sealing straw cover includes a container mouth 1, a straw 2 and a sealing tray made of elastic material such as silica gel are installed in the container opening 1, and the sealing tray is made of a cone Shaped deformation part 3 and the holding part 4 located at the periphery of the deformation part 3, the deformation part 3 is provided with at least one water outlet slit 5, the water outlet slit 5 is located on the suction pipe 2 in the deformation part 3 Within the range of the axial projection above, when the deformed part is squeezed and deformed by the lower end of the straw, the outlet opening is opened to communicate with the core of the straw. The deformation part adopts a tapered structure, which facilitates the reset of the straw, push plate and water outlet.

The straw cover shown in Figures 1 to 6 constituted by the container mouth 1, the straw 2 and the sealing tray can be used alone as a straw lid for a packaging bag, etc. The container mouth 1 can also be integrally formed with the container, or can be inserted As shown in FIG. 7 to FIG. 12 , a container cover 6 is screwed on the container mouth 1 , and the container cover 6 is provided with a straw hole 7 through which the upper end of the straw 2 protrudes.

For the straw cover shown in Figures 1 to 6, a radial limit ring 13 can be set on the top or inner wall of the container mouth 1, and an upper limit ring 8 and a lower limit ring can be arranged on the outer wall of the straw 2 9. The bottom of the lower limit ring is flush with the bottom of the straw. After assembly, the limit ring 13 is located between the upper limit ring 8 and the lower limit ring 9 to prevent the straw from being pulled out or pressed in In the container, the purpose of the bottom of the lower limit ring being flush with the bottom of the straw is that, due to the thinner wall of the straw, when the straw is pressed down, the wall of the straw may pierce the deformed part of the sealing tray. The bottom of the bit ring is flush with the bottom of the straw, which is equivalent to increasing the wall thickness of the straw, which can prevent the deformed portion of the sealed tray from being pierced during use.

For the straw cover shown in Figures 7 to 12, the structure of the straw remains unchanged, that is, the outer wall of the straw 2 is provided with an upper limit ring 8 and a lower limit ring 9, and the bottom of the lower limit ring 9 is in contact with the straw. The bottom of 2 is flush. After assembly, the upper limit ring 8 and the lower limit ring 9 are respectively located on the upper and lower sides of the container cover 6 to prevent the straw from being pulled out or pressed into the container.

For the straw lid with a container lid as shown in FIG. 7 to FIG. 12 , the first fixing method of the sealing tray is that the holding part 4 is sandwiched between the container lid 6 and the end surface of the container mouth 1 . The second fixing method of the sealed tray is shown in Figure 7 and Figure 8, the top of the container cover 6 is provided with a hooking part 10 extending into the container mouth 1, and the lower end of the hooking part 10 is outward The buckle ring 11 is formed by flanging, and the inner wall of the holding part 4 is provided with a groove 12 adapted to the shape of the buckle ring 11 , and the groove 12 is sleeved on the buckle ring 11 after assembly. The third fixing method of the sealed tray is shown in Figure 9 and Figure 10, the inner wall of the container mouth 1 is provided with a radial support part 17, and the inner side of the support part 17 is turned up to form a connecting part 18, the The holding part 4 is provided with an assembly groove 19 with an opening downward. After assembly, the assembly groove 19 is sleeved on the connecting part 18 . The fourth fixing method of the sealed tray is shown in Figure 11 and Figure 12. The inner wall of the container mouth 1 is provided with a radial rest ring 20, the holding part 4 is cylindrical, and the lower end surface of the holding part 4 Rest on the rest ring 20.

For the straw lids without container lids shown in Figures 1 to 6, the first fixing method of the sealed tray is shown in Figures 1 and 2, and the lower end of the limit ring 13 is provided with an axial connecting column 14. The lower end of the connecting column 14 is flanged outward to form a buckle ring 15, and the inner wall of the holding part 4 is provided with a buckle concave ring 16 adapted to the shape of the buckle ring 15. After assembly, the The buckle concave ring 16 is sleeved on the buckle ring 15 . The second fixing method is shown in Figure 3 and Figure 4. This fixing method does not need to rely on the container cover, which is the same as the third fixing method of the sealing tray in the straw cover with a container cover. The third fixing method is shown in Figure 5 and Figure 6. This fixing method also does not need to rely on the container cover, which is the same as the fourth fixing method of the sealing tray in the straw cover with a container cover.

The deformation part of the present invention is provided with at least one water outlet slit. In the natural state, the water outlet slit is naturally closed by elastic action, and the liquid in the container will not spill. When the straw is pressed down, the straw moves down, and the lower end of the straw is squeezed and deformed. The water outlet on the deformed part is opened, and the liquid in the container can flow out. After the hand is released, the elastic action of the sealing tray moves the straw up to form a seal again. The structure is simple and easy to use.

In addition, due to the effect of the inclined sealing ring, when the container is pressurized, even if pressure is generated in the container, the pressure generated can only make the deformation part and the bottom of the straw fit closer together, the greater the pressure, the tighter the fit , to prevent the liquid in the container from flowing out automatically when not drinking or when the container is overturned. Due to the above effects, the wall thickness of the container can be greatly reduced, the use of plastic raw materials can be greatly reduced, and the product cost is saved. When filling liquids, the container can be folded and packaged, which is convenient for transportation and storage, and is also convenient for consumers to use and carry. It can be used in various containers, container barrels, seasoning containers, flexible packaging bags, etc.
