Description

Technical Field

[0001] The present invention relates to the technical field of beverage bottles, in particular to a marking bottle cap. Background Art

[0002] A plastic beverage bottle consists of two main parts: the bottle body and the cap. The bottle body is primarily made of materials such as polyethylene or polypropylene, with the addition of various organic solvents. Plastic bottles are widely made from polyester (PET), polyethylene (PE), and polypropylene (PP). After adding the appropriate organic solvents, they are heated to high temperatures and then blow-molded, extruded, or injected into a plastic mold. These plastic containers are characterized by their durability, low cost, high transparency, and food-grade quality. The cap is typically made of polyolefin and formed through processes such as injection molding and hot pressing. Its function is to ensure ease of opening while maintaining a tight seal to prevent leakage. While plastic bottle caps meet the basic needs of beverage storage, there is one situation in our daily lives where ordinary beverage bottles fall short. At cultural and sports events or conferences, organizers often distribute the same beverage to participants. Among multiple opened and used bottles of the same type, it can be difficult to distinguish which one belongs to you. Existing beverage bottles lack the ability to distinguish between users. Surveys have shown that this problem is quite common among the public. Summary of the Invention

[0003] The purpose of the present invention is to address the defects and shortcomings of the existing technology and provide a rationally designed marking bottle cap with the function of distinguishing owners. Although the cost is slightly increased, it improves the competitiveness of beverages equipped with this bottle cap among similar products on the market, thereby increasing the sales volume of beverages.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: it comprises an upper cover, a middle cover and a lower cover; the inner wall of the lower cover is provided with a lower cover thread, a marking disk is integrally formed on the upper part of the lower cover, a plurality of lower cover distinguishing marks are engraved at equal angles on the marking disk, a plurality of limit slots are opened at equal angles on the outer wall of the marking disk, each limit slot is arranged at the middle position between two adjacent lower cover distinguishing marks, a plurality of lower cover limiting convex points are integrally formed on the outer wall of the root of the marking disk, the lower cover limiting convex points are movably clamped in the middle cover rotation groove opened on the inner wall of the middle cover, and the middle cover is movably sleeved on the marking disk; the middle cover is located above the middle cover rotation groove. A middle cover limiting protrusion is fixed on the inner wall, and the middle cover limiting protrusion is movably locked with the limiting slot; a reading hole is provided at a position where the cover surface of the middle cover deviates from the central axis, and a middle cover marking convex point is integrally formed on the cover surface of the middle cover on the side of the reading hole; the reading hole and the lower cover distinguishing mark are movably arranged in correspondence with each other; a middle cover shaft is integrally formed upward from the center position of the cover surface of the middle cover, and a middle cover limiting slot is provided on the outer ring wall of the middle cover shaft, and the middle cover limiting slot is movably locked with the upper cover limiting convex point integrally formed on the inner wall of the upper cover, and the upper cover is movably sleeved on the middle cover shaft, and several upper cover distinguishing marks are engraved at equal angles on the outer wall of the upper cover.

[0005] Furthermore, the outer wall of the middle cover is provided with a middle cover anti-slip groove.

[0006] Furthermore, the outer wall of the lower cover is provided with a lower cover anti-slip groove.

[0007] Furthermore, 12 lower cover distinguishing marks are engraved at equal angles on the marking plate, and 6 upper cover distinguishing marks are engraved at equal angles on the outer wall of the upper cover.

[0008] The working principle of the present invention is as follows: the whole is tightened on the mouth of the beverage bottle using the lower cover thread (the lower cover thread matches the existing beverage bottle mouth thread). After opening the beverage bottle cap (lower cover) for drinking, the middle cover is rotated and one of the lower cover distinguishing marks is selected to correspond to the reading hole. At this time, the middle cover uses the middle cover limiting protrusion on the inner wall to cooperate with the limiting card slot to limit and fix it. Then the upper cover is rotated again and one of the upper cover distinguishing marks is selected to correspond to the position of the middle cover marking convex point. At this time, the lower cover distinguishing mark and the upper cover distinguishing mark constitute an identification combination. Multiple lower cover distinguishing marks and multiple upper cover distinguishing marks constitute multiple groups of identification combinations for distinguishing multiple drinkers.

[0009] After adopting the above structure, the beneficial effect of the present invention is: the present invention provides a marked bottle cap with the function of distinguishing owners. Although the cost is slightly increased, it improves the competitiveness of beverages equipped with this bottle cap among similar products on the market, thereby increasing the sales volume of beverages.

[0017] like Figure 1-Figure 4As shown, this specific embodiment adopts the following technical solution: it includes an upper cover 1, a middle cover 2 and a lower cover 3; the outer wall of the lower cover 3 is provided with a lower cover anti-slip groove 3-4, the inner wall of the lower cover 3 is provided with a lower cover thread 3-5, the upper part of the lower cover 3 is integrally formed with a marking plate 3-1, 12 lower cover distinguishing marks 3-6 are engraved on the marking plate 3-1 at equal angles, and 12 limit slots 3-2 are opened at equal angles on the outer wall of the marking plate 3-1, each limit slot 3-2 is set at two adjacent lower cover areas At the middle position of the sub-marker 3-6, the outer wall of the root of the marking disk 3-1 is integrally formed with several lower cover limiting protrusions 3-3, and the lower cover limiting protrusions 3-3 are movably clamped in the middle cover rotation groove 2-5 opened on the inner wall of the middle cover (to prevent axial movement of the upper cover 1), and the middle cover 2 is movably sleeved on the marking disk 3-1; the outer wall of the middle cover 2 is provided with a middle cover anti-slip groove 2-6; the inner wall of the middle cover 2 above the middle cover rotation groove 2-5 is glued and fixed with a middle cover limiting protrusion made of soft plastic material 2-4, the middle cover limiting protrusion 2-4 is movably locked with the limiting card slot 3-2 (the outer end surface of the middle cover limiting protrusion 2-4 is an arc-shaped structure, and it has a certain elasticity, which can meet the normal rotation of the middle cover 2 relative to the lower cover 3. When it encounters the limiting card slot 3-2, it is locked into the limiting card slot 3-2 under its elastic action); a reading hole 2-3 is opened at a position deviating from the central axis of the cover surface of the middle cover 2, and a middle cover is integrally formed on the cover surface of the middle cover 2 on the side of the reading hole 2-3. Marking convex point 2-2; the reading hole 2-3 and the lower cover distinguishing mark 3-6 are arranged to correspond to each other in an upward and downward movement; a middle cover shaft 2-7 is integrally formed with the center position of the cover surface of the middle cover 2, and a middle cover limiting card groove 2-1 is opened on the outer ring wall of the middle cover shaft 2-7. The middle cover limiting card groove 2-1 is movably engaged with the upper cover limiting convex point 1-1 integrally formed on the inner wall of the upper cover, and the upper cover 1 is movably sleeved on the middle cover shaft 2-7. Six upper cover distinguishing marks 1-2 are engraved at equal angles on the outer wall of the upper cover 1.

[0018] The working principle of this specific embodiment is: the whole is tightened on the bottle mouth of the beverage bottle using the lower cover thread 3-5 (the lower cover thread 3-5 matches the existing beverage bottle mouth thread). After opening the beverage bottle cap (lower cover 3) for drinking, the middle cover 2 is rotated, and one of the lower cover distinguishing marks 3-6 is selected to correspond to the reading hole 2-3.
