Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, and in particular to a PE bottle sealing cap. Background Technology

[0002] Bottle caps are used to seal bottles. Depending on their function, bottle caps come in different shapes and have different operating methods. Bottle caps are a crucial part of food and beverage packaging and are the first point of contact between the consumer and the product. They maintain the airtightness of the contents and also provide anti-theft and security functions, thus being widely used in bottled products. Currently, plastic bottles are the most widely used, including PE bottles.

[0003] A document with publication number CN214242010U discloses a double-layer high-sealing PE cap, including an outer cap. During packaging, the bottom cap can be placed on the bottle opening and rotated clockwise to seal the bottle. The inner cap seals the bottle opening, and a sealing gasket further seals the opening. A patch ensures a tight fit between the PE cap and the bottle, further enhancing the sealing effect. After tightening the bottom cap, rotating the knob clockwise simultaneously rotates the turntable, causing it to move downwards and expel air from the top cap through the vent hole into the bottom cap. Since the bottom cap is already sealed, this increases the air pressure inside, providing a certain airtight seal and further improving the sealing effect of the bottle opening. This double-layer sealing structure (bottom cap + top cap) significantly improves the sealing effect of the bottle compared to ordinary bottle caps, greatly reducing the probability of leakage and improving the packaging quality of the product.

[0004] However, while this type of cap provides a good seal, it cannot regulate the flow rate of the liquid inside the bottle from the opening, making it unsuitable for liquids that require slow pouring.

[0005] Therefore, it is necessary to provide a PE bottle sealing cap to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a PE bottle sealing cap that can conveniently control the outflow rate of liquid.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The PE bottle sealing cap includes a bottom cap and an upper cap rotatably mounted on the bottom cap. A stopper is threaded onto the inner side of the upper cap. The stopper has a central protrusion. A guide mechanism is provided between the stopper and the bottom cap so that the stopper can only move in a straight line. A drain hole is provided on the top of the upper cap. A third sealing ring is installed inside the drain hole. The top of the stopper is pressed tightly against the third sealing ring. Multiple liquid channels are provided on the stopper.

[0009] Preferably, the guiding mechanism includes a guide hole opened on the bottom cover, and a guide rod installed at the bottom of the top cover, with the guide rod inserted into the guide hole.

[0010] Preferably, the bottom cover and the top cover have the same thread direction.

[0011] Preferably, a first sealing ring is installed inside the bottom cover.

[0012] Preferably, a second sealing ring is installed between the bottom cover and the top cover.

[0013] Preferably, a sealing sticker is installed on the top of the cover.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) This utility model sets a bottom cover, a top cover and a plug. By rotating the top cover alone, the plug can be lowered inside the top cover. The distance between the plug and the drain hole can be adjusted, thereby making it easier to control the flow rate of the liquid. It also has multiple usage modes and is more flexible in use.

[0016] (2) By installing a sealing sticker on the top of the cap, this utility model can seal the outside of the drain hole, thereby improving the sealing performance of the cap.

[0017] (3) By setting a guiding mechanism including a guide hole and a guide rod, this utility model can conveniently guide the plug. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0023] Example 1:

[0024] like Figure 1-3 As shown, the PE bottle sealing cap provided by this utility model includes: a bottom cover 1 and an upper cover 2 rotatably connected to the bottom cover 1. The bottom cover 1 is threadedly installed at the bottle mouth 3 of the PE bottle. A first sealing ring 4 is installed inside the bottom cover 1, which seals the bottom cover 1 and the bottle mouth 3 of the PE bottle. A second sealing ring 5 is installed between the bottom cover 1 and the upper cover 2, which seals the gap between them. A stopper 6 is threadedly installed inside the upper cover 2. The top of the stopper 6 has a raised center. A guide mechanism is provided between the stopper 6 and the bottom cover 1, which allows the two to slide together, so that the stopper 6 can only move up and down in a straight line. A drain hole 9 is opened on the top of the upper cover 2. A third sealing ring 10 is installed inside the drain hole 9. The top of the stopper 6 presses tightly against the third sealing ring 10, so that the drain hole 9 is sealed. Multiple liquid channels 11 are opened on the stopper 6. When using the PE bottle, the first method is to unscrew the bottom cap 1 to remove the cap and pour out the liquid. However, the pouring speed is not easy to control. The second method is to keep the bottom cap 1 still and rotate the top cap 2 to move the stopper 6 so that its top is no longer in contact with the third sealing ring 10. When pouring the PE bottle, the liquid in the bottle passes through the liquid channel 11 of the stopper 6, then through the gap between the stopper 6 and the third sealing ring 10, and finally flows out from the drain hole 9. By adjusting the distance between the three stops 6 and the third sealing ring 10, the pouring speed can be easily controlled, which is especially suitable for liquids that need to be poured slowly.

[0025] By setting a bottom cover 1, an upper cover 2, and a stopper 6, the stopper 6 can be lowered inside the upper cover 2 by rotating the upper cover 2 alone. The distance between the stopper 6 and the drain hole 9 can be adjusted, thereby making it easy to control the outflow speed of the poured liquid. It also has multiple usage modes and is more flexible to use.

[0026] Example 2:

[0027] like Figure 2-3 As shown, a sealing sticker 12 is installed on the top of the cap 2 to seal the outside of the drain hole 9, thereby improving the sealing performance of the cap. When in use, the sealing sticker 12 is removed to expose the drain hole 9, making it convenient to pour out the liquid inside the bottle.

[0028] By installing a sealing sticker 12 on the top of the cap 2, the outside of the drain hole 9 can be sealed, thus improving the sealing performance of the cap.

[0029] Example 3:

[0030] like Figure 2-3 As shown, the guiding mechanism includes a guide hole 7 opened on the bottom cover 1, and a guide rod 8 installed at the bottom of the top cover 2. The guide rod 8 is inserted into the guide hole 7. When in use, when the top cover 1 rotates, the plug 6 descends, and the guide rod 8 slides in the guide hole 7, thereby preventing the plug 6 from rotating.

[0031] By setting a guiding mechanism including a guide hole 7 and a guide rod 8, the plug 6 can be easily guided.

[0032] Example 4:

[0033] In this embodiment, the threads on the bottom cover 1 and the top cover 2 are in the same direction, so that when the bottle cap is installed on the PE bottle, you only need to hold the top cover 2 and turn it clockwise to tighten the bottle cap onto the bottle mouth 3 of the PE bottle. Hold the bottom cover 1 with one hand and the top cover 2 with the other hand, and turn the top cover 2 counterclockwise to make the bottom cover 1 and the top cover 2 rotate relative to each other, and the sealing relationship between the bottom cover 1 and the PE bottle remains unchanged, and the stopper 6 can descend.

[0034] By setting the bottom cap 1 and top cap 2 with the same thread direction, the bottle cap can be easily tightened and installed.

[0035] Working principle: When using the product, if you need to pour out liquid from the PE bottle:

[0036] The first method is to unscrew the bottom cap 1 to remove the bottle cap and pour out the liquid in the PE bottle. However, the liquid pouring speed is not easy to control and is more suitable for occasions where liquid needs to be poured quickly. The second method is to keep the bottom cap 1 still and rotate the top cap 2 to move the stopper 6 so that its top is no longer in contact with the third sealing ring 10. When pouring the PE bottle, the liquid in the bottle passes through the liquid channel 11 of the stopper 6, then through the gap between the stopper 6 and the third sealing ring 10, and finally flows out from the drain hole 9. By adjusting the distance between the three blocks 6 and the third sealing ring 10, the liquid pouring speed can be easily controlled, which is especially suitable for liquids that need to be poured slowly.
