Description
Technical Field
[0001] This utility model relates to the field of bottle cap technology, and in particular to a novel medicine bottle cap. Background Technology
[0002] Existing medicine bottles consist of a bottle body, a rubber stopper, and a cap. The bottle body has an opening, and the rubber stopper is located between the bottle body and the cap. The rubber stopper seals the opening, and the cap is threaded or snap-fitted to the opening to seal the medicine within the bottle body. When people take oral liquids, they need to remove the cap and take out the rubber stopper to consume the medicine. However, with this bottle structure, if the rubber stopper is put on and then the cap is placed on the opening, the bottle appears unopened, making it impossible for people to determine whether the bottle has been tampered with, posing a safety risk.
[0003] Existing technology also includes an easy-tear medicine bottle cap with a tamper-evident tear strip design. The cap can be opened simply by tearing off the strip, making it simple and convenient to use. For ease of manufacturing, most caps have a retainer and tear strip between the top and bottom caps. The bottle is opened by tearing off the strip. However, after tearing the strip from between the top and bottom caps, the bottle appears unopened, making it impossible for consumers to determine if the bottle has been tampered with. This poses a security risk, as consumers may perceive the cap as consisting only of the top and bottom caps, leading to misjudgment. Therefore, we propose a novel medicine bottle cap. Utility Model Content
[0004] The main purpose of this utility model is to propose a new type of medicine bottle cap, which can effectively solve the problems in the background art.

[0026] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.
[0027] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] Please see Figure 1-5 This utility model provides a technical solution: a novel medicine bottle cap, comprising:
[0030] The upper cover 1 has a lower cover 2 below it. The upper cover 1 is a bottle cap structure with an open bottom. The lower cover 2 is a ring structure with threads on the inner wall for threaded connection with the mouth of the medicine bottle. A connecting piece 7 is fixedly connected to the lower end of one side of the upper cover 1.
[0031] Hinge 3 is fixedly connected between the upper cover 1 and the lower cover 2 and is integrally molded. The upper cover 1 can be folded relative to the lower cover 2 by means of hinge 3. It should be noted that hinge 3 is made of plastic material with a certain degree of flexibility and elasticity, such as common plastics such as polypropylene (PP) and polyethylene (PE). These plastics have good toughness and can be bent to a certain extent without breaking. During the production process, these materials are further optimized for flexibility through specific formulas and processing technology to meet the requirements of frequent bending of the hinge.
[0032] Easy-tear groove 4 is a slot formed between the upper cover 1, the lower cover 2 and the hinge 3.
[0033] The easy-tear section 5 is located inside the easy-tear groove 4. The easy-tear section 5 includes a tear strip 51, which is looped within the easy-tear groove 4. A second easy-tear strip 52 is fixedly connected to both the top and bottom ends of the tear strip 51. The top end of the second easy-tear strip 52 at the top of the tear strip 51 is heat-pressed to the bottom end of the upper cover 1, and the top end of the second easy-tear strip 52 at the bottom of the tear strip 51 is heat-pressed to the top end of the lower cover 2. A connecting block 53 is fixedly connected to the side wall of the tear strip 51 near the hinge piece 3. A tear piece 8 is fixedly connected to the connecting block 53, and both the top and bottom ends of the tear piece 8 are fixedly connected... A third easy-tear strip 9 is attached. The ends of the two third easy-tear strips 9 away from the tear strip 8 are respectively heat-pressed to the outer wall of the upper cover 1 and the outer wall of the lower cover 2. When the tear strip 8 is pulled, since the tear strip 8 and the tear strip 51 are fixedly connected by the connecting block 53, and the second easy-tear strips 52 at the top and bottom of the tear strip 51 are respectively heat-pressed to the bottom of the upper cover 1 and the top of the lower cover 2, under the force of pulling the tear strip 8, the weakened part of the second easy-tear strip 52 connected to the upper cover 1 and the lower cover 2 is torn open by force, so that the tear strip 51 can be torn off between the upper cover 1 and the lower cover 2.
[0034] The connecting part 6 is fixedly connected between the side walls of the upper cover 1 and the lower cover 2. The connecting part 6 includes a connecting strip 61. A fixing strip 62 is fixedly connected to the lower end of one side of the connecting strip 61. The other side of the fixing strip 62 is fixedly connected to the side wall of the lower cover 2. A first easy-tear strip 63 is fixedly connected to the upper end of one side of the connecting strip 61. The end of the first easy-tear strip 63 away from the connecting strip 61 is heat-pressed to the side wall of the upper cover 1. When the tear strip 51 is torn off, it will pass through the location of the connecting part 6. At this time, the tear strip 51 will pull the connecting strip 61. After the connecting strip 61 is stressed, the first easy-tear strip 63, which is heat-pressed to the upper cover 1, will separate from the upper cover 1. The fixing strip 62 will remain fixedly connected to the lower cover 2. In this way, after the tear strip 51 is torn off, a connecting part 6 that is separated from the upper cover 1 will remain on the lower cover 2, thereby reminding the person that the bottle cap has been opened.
[0035] It should be noted that the bottle cap is a plastic product made entirely of PET or HDPE. The hot-press connection mentioned above is a commonly used easy-tear strip connection. For plastic bottle caps, a hot-press process is often used to connect the easy-tear strip to the bottle cap body. During the hot-press process, by heating and applying pressure, the plastic material at the contact area between the easy-tear strip and the bottle cap melts and fuses together to form a strong connection. However, a weakened structure is designed at the connection point, such as forming some small gaps or thinner areas at the connection point, so that it can be torn along these weakened areas when needed.
[0036] It should be noted that this utility model is a novel medicine bottle cap. When using it, hold the medicine bottle, locate the tear strip 8 on the cap, pinch the tear strip 8 with your fingers, and pull it forcefully in the direction of application (usually outwards). With the pulling force, the second easy-tear strip 52 at the top and bottom of the tear strip 51, which connects to the upper cap 1 and lower cap 2 respectively, begins to tear. The tear strip 51 gradually separates from the upper cap 1 and lower cap 2. Once the tear strip 51 is torn off... During the process, the device passes through the connecting part 6 and pulls the connecting strip 61. The first easy-tear strip 63 on the connecting strip 61, which is heat-pressed to the upper cover 1, separates under force, while the fixing strip 62 remains fixedly connected to the lower cover 2. Finally, the connecting part 6, which is separated from the upper cover 1, remains on the lower cover 2, indicating that the bottle cap has been opened. After the tear strip 51 is completely torn off, the upper cover 1 is flipped open relative to the lower cover 2 using the flexibility and elasticity of the hinge 3. At this point, the medicine bottle can be opened and the medicine can be taken out. Compared with existing new medicine bottle caps, by designing the easy-tear part and connecting part structure, when the bottle cap is opened, the connecting part remains on the lower cover while the tear strip is torn off, which can intuitively remind people that the medicine bottle has been opened and effectively avoid safety risks.
