Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a rotary injection type functional bottle cap. Background Art

[0002] Consumers are increasingly favoring beverages with health and wellness benefits. However, these existing beverages typically involve mixing these functional powders directly into water. To extend their shelf life, these beverages often require the addition of preservatives, antistaling agents, stabilizers, and other ingredients harmful to human health. Consequently, growing awareness of the health risks associated with bottled beverages has emerged. To address this issue, a beverage bottle cap has emerged that allows for instant mixing of ingredients. Prior to consumption, the ingredients are separated from the water, allowing for immediate, ready-to-use mixing without the use of additives.

[0003] To this end, the patent specification with publication number CN209351883U discloses a rotary injection functional bottle cap, comprising a lower bottle cap and an upper bottle cap rotatably connected to the lower bottle cap, a powder storage chamber is provided in the upper bottle cap, one end of the powder storage chamber is an open end, and the other end is a closed end, the lower bottle cap comprises an upper connecting part and a lower connecting part, the lower connecting part is provided with a bottom sealing plate for closing the open end of the powder storage chamber, the bottom sealing plate is provided with a sealing rib adapted to the inner surface of the open end of the powder storage chamber, the outer edge of the sealing rib is provided with a positioning groove engaged with the open end of the powder storage chamber, the lower connecting part is also provided with an inner ring wall extending vertically downward from the upper connecting part, the outer edge of the bottom sealing plate is evenly provided with a plurality of connecting ribs along the circumferential direction, the upper end of the connecting rib is connected to the inner ring wall, and a leakage port is formed between two adjacent connecting ribs.

[0004] The aforementioned rotary injection functional bottle cap has drawbacks. First, although it can form a leak opening by rotating, the upper bottle cap at the top of the powder storage chamber easily forms a negative pressure zone, making it difficult to quickly discharge the powder. Second, there is no flow guide at the penetration point. Therefore, its structure needs to be optimized and improved. Summary of the Invention

[0005] The purpose of the utility model is to overcome the above problems existing in the traditional technology and provide a rotary injection type functional bottle cap.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0007] A rotary injection functional bottle cap comprises an upper bottle cap and a lower bottle cap rotatably connected to the upper bottle cap, the upper bottle cap comprising an upper bottle cap body, a powder storage tube is mounted on the inner side of the top end of the upper bottle cap body, the bottom end of the powder storage tube is open, a powder plucking assembly is mounted inside the powder storage tube, the powder plucking assembly comprises a positioning block, a rotating head, a vertical shaft, an inclined baffle and a powder plucking plate, the positioning block is mounted on the top wall of the inner cavity of the powder storage tube, the top end of the vertical shaft is provided with a rotating head movably restricted in the positioning block, the bottom end of the vertical shaft is mounted with an inclined baffle, and the outer side of the vertical shaft is mounted with a plurality of powder plucking plates;

[0008] The lower bottle cap includes a lower bottle cap body, an insertion cavity is provided inside the lower bottle cap body for facilitating the insertion of a powder storage tube, a powder outlet is provided at the bottom side end of the insertion cavity, a guide cone is provided in the middle of the bottom plate of the insertion cavity, and a plurality of protrusions are evenly distributed along the circumference on the outer side of the guide cone for preventing the inclined baffle from rotating randomly.

[0009] Furthermore, in the above-mentioned rotary injection type functional bottle cap, an anti-theft ring is provided on the outer surface of the upper bottle cap body, and a first anti-slip ring is provided on the inner side of the portion of the upper bottle cap body below the anti-theft ring.

[0010] Furthermore, in the above-mentioned rotary injection type functional bottle cap, a second anti-slip ring cooperating with the first anti-slip ring is provided on the outer side of the lower bottle cap body below the external threaded portion.

[0011] Furthermore, in the above-mentioned rotary injection type functional bottle cap, the lower portion of the lower bottle cap body is provided with a snap-on groove portion or a screw-on groove portion for facilitating connection with the bottle body.

[0012] Furthermore, in the above-mentioned rotary injection functional bottle cap, an annular sealing groove is provided at the edge of the bottom plate of the insertion cavity, which cooperates with the bottom end of the powder storage tube.

[0013] Furthermore, in the above-mentioned rotary injection type functional bottle cap, the lower side surface of the inclined baffle is against the outer surface of the guide cone head.

[0014] Furthermore, in the above-mentioned rotary injection type functional bottle cap, the rotating head, vertical axis, inclined baffle and powder diverter plate are an integrated structure.

[0015] The beneficial effects of the utility model are:

[0016] The utility model has a reasonable structural design. By twisting the upper bottle cap and the lower bottle cap relative to each other, the anti-theft ring of the upper bottle cap is broken, and the upper bottle cap and the lower bottle cap can be freely detached. When the powder needs to flow out, the upper bottle cap is first rotated several times relative to the lower bottle cap. During the rotation of the upper bottle cap, the powder shifting component therein is blocked by the convex point in the lower bottle cap and will not rotate synchronously. Therefore, the powder shifting component can loosen the compacted powder in the powder storage tube. In this way, when the upper bottle cap and the lower bottle cap are detached, the powder can quickly flow out from the powder outlet under the action of the guide cone head.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
