Description

bottle cap with straw

technical field

The utility model relates to a packaging container, in particular to a bottle cap with a straw structure.

Background technique

In the prior art, the bottle cap installed on the bottle mouth has only a single function of opening and covering. For example, the cap on the beverage bottle is screwed on the bottle mouth in a screw-in manner. When opened, if the beverage in the bottle If the drink in the bottle needs to be taken away without finishing the drink, the cap must be re-screwed by hand. If the cap is not closed, the drink in the drink bottle will be easily contaminated, and the liquid in the bottle will leak out when the bottle body is knocked over. In addition, in order to prevent the liquid in the bottle from flowing out of the bottle mouth automatically when the bottle is under pressure, it is usually necessary to increase the thickness of the bottle to make the bottle have a certain strength, which 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 Figures 1 to 13, a bottle cap with a straw includes a cover body 1, the lid body 1 is provided with a straw hole, and a straw 3 that can move up and down is installed in the straw hole, and the top of the straw 3 Closed, the lower end is provided with a water inlet; the upper side wall of the suction pipe 3 has a water outlet 5 connected with the water inlet, and when the suction pipe 3 is moved down, the water outlet 5 is located at the bottom of the suction pipe hole. Side, in order to pull up the straw conveniently, the top of the straw can be provided with a handle 2 or a pull ring as shown in Figure 8, Figure 9, Figure 12, and Figure 13.

In normal state, the straw moves down, and the water outlet on the side wall of the upper end of the straw is located on the lower side of the straw hole. Because the seal is formed between the straw hole and the outer wall of the straw, the liquid in the bottle will not flow out. When in use, pull up the straw to make it The water outlet is exposed, the liquid in the bottle enters from the water inlet at the lower end of the straw, and flows out from the water outlet, and the water flows out smoothly. After use, press down the straw to form a seal again to prevent the liquid in the bottle from spilling. The structure is simple and easy to use convenient.

In this embodiment, there are two ways of sealing between the straw hole and the straw 3. The first one is that the outer diameter of the straw is equal to the inner diameter of the straw hole, and the straw 3 is tightly inserted into the straw hole. Both the straw 3 and the straw 3 are made of plastic material with certain elasticity, and the inner wall of the straw hole can form a seal with the outer wall of the straw 3. The second sealing method is to install an elastic material between the straw hole and the straw 3. The sealing ring 6, because the material of the sealing ring 6 is softer than the material of the straw hole and the straw 3, and more elastic, a better sealing effect can be formed between the straw 3 and the straw hole.

In this embodiment, there are three installation methods of the sealing ring 6, the first installation method is shown in Fig. 4 and Fig. Inside the step, adhesive is coated between the sealing ring and the contact surface of the step, and a seal is formed between the inner wall of the sealing ring 6 and the outer wall of the suction pipe 3 . The second installation method is shown in Figure 1 and Figure 2. The inner diameter of the straw hole is larger, and the outer periphery of the sealing ring is bonded in the step, and the inner part extends downwards to enclose the inner wall of the straw hole. The inner side walls of the holes do not touch. Refer to Figure 6 to Figure 8, Figure 10, Figure 12, and Figure 13 for the third installation method, the top of the cover 1 is provided with a connecting wall 8 extending downward, and the sealing ring 6 is installed on the connecting wall 8 Inside, glue is coated on the surface of the sealing ring 6 in contact with the connecting wall 8 and the cover body 1 .

The straw and the cover can be made separately and then assembled, or they can be integrally injection molded during the injection molding process. For the integral molding of the straw and the cover, it is necessary to set an easy-to-open structure between the straw and the cover. Two structures are provided in the embodiment. The first structure is shown in Fig. 8 and Fig. 9. A thin-walled part 9 or a closed tearing scratch is provided between the straw 3 and the cover 1. When pressing down on the straw or pulling it out upwards, the thin-walled part 9 or the tearing scratch will break, so that the straw is separated from the cover, and the straw can move up and down in the straw hole. The second structure is shown in Figures 10 and 12. As shown, two closed tearing parts 10 are provided between the straw 3 and the cover body 1, and the tearing parts 10 can be thin-walled or scratched, etc., and the two tearing parts 10 The part between them forms a tear ring 11, and the tear ring 11 is connected with a pull ring 12. When opening, hold the pull ring 12 and pull the tear ring 11 off along the two tear parts 10, so that the straw and the lid Once the body is separated, the straw can move up and down in the straw hole.

The shape of the straw can have many kinds. In the present embodiment, the straw used has two types: cylindrical and a truncated cone with the lower end larger than the upper end. In order to prevent the straw from being pressed into the bottle, an upper limit ring 7 is provided on the side wall of the upper end of the straw. , the outer diameter of the upper limit ring 7 is greater than the outer diameter of the straw hole, the end side wall of the straw is provided with a lower limit ring 4, the outer diameter of the lower limit ring 4 is greater than the inner diameter of the straw hole, which can prevent the straw from breaking away during the pull-up process bottle cap. For the frustum-shaped straw, when it is pulled up for a certain distance, the large end of the straw will block its further upward movement. On the one hand, it can play a position-limiting role. The tightness between the straws is better, and when in use, the liquid in the bottle will not flow out from the gap between the outer wall of the straw and the inner wall of the straw hole or the sealing ring.
