Description

Butter bottle straw stop attachment structure

technical field

The utility model is related to a plastic bottle, and more specifically, especially refers to an anti-adhesion structure for setting a straw in a plastic bottle.

Background technique

Plastic bottles have the characteristics of large capacity, easy to carry, good sealing, unbreakable, and low cost. Therefore, they are widely favored by the beverage industry and have become the most widely used beverage containers. However, for drinking beverages in plastic bottles, other cups must be provided in addition, otherwise it is necessary to drink from the bottle. It is inconvenient to prepare additional cups, and it is difficult for female consumers to accept the bottle by mouth. Therefore, many people still use straws to drink beverages from plastic bottles. However, the size of the current general-purpose straw is usually shorter than the shaft of the plastic bottle. When using it, you must pull out and hold the straw with your fingers, but once you let go, the straw will fall into the bottle, making it difficult to take it out for use.

Contents of the invention

In view of this, the inventors conducted research on the straw attached to the plastic bottle, and then created a structure with a simplified structure, simple installation, and good straw-stopping function.

The problem solved by the utility model is to provide a special structure for the suction pipe of the special bottle, so that the suction pipe can be positioned in the straight direction in the special bottle, and is not subject to unstable situations such as shaking, sinking, floating, and detaching from the bottle body. impact; and the straw can be extended for use, and can also be retracted and hidden in the bottle cap. At the same time, the anti-attachment structure can also be used as the inner pad of the bottle cap to play the sealing function of eliminating the gap between the bottle mouth and the bottle cap. And when the straw is not attached, you can also drink directly from the bottle or pour out the drink in the bottle.

Another purpose of the present utility model is to provide a suction pipe stop structure for plastic bottles, which is simple in structure and low in cost. The design method is simple.

The technical solution of the utility model is as follows:

An anti-attachment structure for a straw of a plastic bottle, the anti-adhesion structure includes a set of rings, which are set in the mouth of the bottle; the top of the ring forms a lap and overlaps the top of the bottle mouth; Several anti-adhesion walls are extended toward the center of the circle at intervals, and several openings are formed between the several anti-adhesion walls. The open ends of the several anti-adhesion walls are connected by a ring, and a suction pipe can pass through the center of the ring. A shallow groove is arranged on the outside of the collar, and a ring pattern is protruded on the inner wall of the bottle mouth. The collar is placed in the bottle mouth, and the ring pattern is clipped into the shallow groove.

The positive progressive effect of the present utility model is:

1. The structure is simple and the cost is low. It can be manufactured in different sizes with various special bottle mouths. It is positioned on the bottle mouth by a sleeve, and the installation method is simple.

2. The collar provides a good anti-adhesion effect for the straw, so that the straw can be positioned straight in the plastic bottle without being affected by unstable situations such as shaking, sinking, floating, and detaching from the bottle.

3. The straw can be extended for use, and can also be shrunk and hidden in the bottle cap, which is quite convenient for drinking beverages in the bottle in batches.

4. When the straw is stored in the bottle cap, it has the protection effect of dustproof and anti-pollution, ensuring the hygiene of drinking next time.

5. In addition to the function of stopping the straw, the collar can also be used as a gasket in the bottle to seal the gap between the bottle mouth and the bottle cap.

6. Even if the user does not use the attached straw, when drinking from the bottle or pouring out the beverage in the bottle, the beverage can flow out through the opening formed between the attached wall without affecting drinking. And the collar is positioned by the shallow groove and the ring pattern of the bottle mouth, the collar has no possibility of detaching from the bottle mouth, and has safety in use.

7. In addition, the collar can also adapt to the current existing bottle cap mode.

Detailed ways

As shown in Fig. 1 to Fig. 4, the utility model is a special bottle suction pipe stop attachment structure, and the attachment stop structure includes:

A set of rings 10 is an annular sleeve made of a slightly elastic material (such as plastic), and its outer diameter is equivalent to the inner diameter of the bottle mouth 21 of the special bottle 20, and is sleeved in the mouth of the bottle 21. The inner wall of the bottle mouth 21 is closely attached; the collar 10 is provided with a shallow groove 15, and the inner wall of the bottle mouth 21 is protruded with a ring pattern 211. When the collar 10 is placed in the bottle mouth 21, the ring pattern 211 snaps into the shallow groove In 15, the collar 10 is positioned without the possibility of breaking away from the bottle mouth. The top of the collar 10 is turned outward to form a lap 11 , and the lap 11 is lapped on the top of the bottle mouth 21 , so that the collar 10 is limitedly placed in the bottle mouth 21 .

Several anti-adhesion walls 12 extend several thin slices at equal intervals from the bottom of the collar 10 to the center of the circle, and a hollow 13 is formed between each anti-adhesion walls 12; The ring 14 is connected, and a suction pipe 30 can be passed through the ring 14, and the bottom end of the pipe extends to the bottom of the bottle.

The pipe body of the straw 30 is provided with a circularly inwardly concave locking portion 31 near the top, for positioning the ring 14 in the center of the attachment wall 12, and the structure of the locking portion 31 is designed to facilitate the suction pipe 30 from above. It penetrates downwards into the ring 14, but it has a stop effect when pulled in the opposite direction. An embodiment of the locking part 31 of the present invention is to set a groove on the body of the suction pipe 30 with a section that is inclined upwards and flattened downwards. The pipe body of the straw 30 is adjacent to the top of the locking portion 31 and is provided with a telescopic section 32, so that the pipe section above the mouth of the straw 30 can be stretched and stretched. A bottle cap 40 (as shown in Figure 2) is screwed on the mouth 21; Unscrew the bottle cap 40 and stretch this straw 30 with fingers so that the top end of the pipe protrudes from the bottleneck 21 and is in a stand-by state for the user to drink (such as Figure 4).

The bottle cap 40 can be in several patterns; as shown in Figure 2, when the straw 20 shrinks and is accommodated in the bottle mouth 21, the bottle cap 40 can adopt the existing flat cap pattern, and utilize the edge 11 of the collar 10 for the The inner top of the bottle cap 40 is pressed to eliminate the gap between the bottle cap 40 and the top of the bottle mouth 21 to achieve an airtight effect. As shown in Fig. 5, a convex part 42 is set on the top of the bottle cap 41, and the straw 30 extended in the convex part 42 protrudes from the pipe end of the bottle mouth 21, so that when the bottle cap 40 is opened, it can be seen that it is in a standby state. straw 30. As shown in Figure 6, the overall interior of the bottle cap 43 is sufficient to accommodate the straw 30 whose pipe end protrudes from the bottle mouth 21 and is in a standby state. The inner wall is extended to the sealing block 44 of the inner wall of the bottle mouth 21, and the bottle cap 43 is spun on the bottle mouth 21, and the gap between the bottle cap 43 and the bottle mouth 21 is eliminated by the sealing block 44 to achieve an airtight effect.
