Description

Technical Field

[0001] This invention relates to a beverage bottle and its cap. Background Technology

[0002] In the field of beverage packaging technology, solid-liquid separation design has become an important technological direction for extending product shelf life and reducing reliance on additives. Traditional premixed beverages rely on preservatives or stabilizers to maintain stability because their active ingredients (such as probiotics, vitamins, and anthocyanins) are easily affected by factors such as light, oxygen, and microorganisms. However, these additives may pose potential health hazards. By storing solid additives separately from water, they can be mixed immediately upon use, avoiding the use of preservatives and maximizing the preservation of the efficacy of active ingredients. For example, the survival rate of live bacteria in probiotic beverages can be increased by more than 80%.

[0003] Since solid additives are usually located in the cap, and pure water is sealed in the bottle through a membrane, when the membrane is punctured, the solid additives, being non-flowing, cannot all enter the bottle. If the bottle is inverted to allow water to enter the cap, it must be screwed all the way to the bottom so that the top of the cap contacts the bottle opening for a complete seal. This requires the user to screw the cap on many times. Because the cap contains solid additives and has spikes, and the cap is relatively long, it requires even more turns to screw it all the way on, which is very inconvenient. If it is not screwed on properly, leakage is likely to occur at the threaded connection between the cap and the bottle opening, especially when the solid additives contain effervescent components, as the generated gas is more likely to cause the beverage to leak, affecting the user experience. Summary of the Invention

[0004] The purpose of this invention is to provide a beverage bottle and its cap that can maintain a continuous seal between the cap and the bottle opening, and eliminate the need to screw the cap all the way to the bottom before mixing by inverting, thereby improving the convenience of use.

[0005] The technical solution of the bottle cap of the present invention is as follows: The bottle cap includes:

[0006] The cover includes a top plate and a surrounding plate, the surrounding plate having internal threads;

[0007] Spikes are located inside the cover and on the top plate;

[0008] The dynamic sealing assembly includes an elastic telescopic tube that is elastically expandable and contractable along its axial direction. The upper end of the elastic telescopic tube is fixedly connected to a top plate, and the lower end of the elastic telescopic tube has an annular sealing portion. The lower surface of the annular sealing portion is used to seal against the upper opening edge of the bottle. The elastic telescopic tube and the spike form a receiving cavity for receiving solid additives.

[0009] Based on the above scheme, the following improvements are made: the elastic telescopic tube includes at least two telescopic sleeves and an elastic element that provides elastic force to the telescopic sleeves in the extension direction.

[0010] Based on the above scheme, further improvements are made as follows: the elastic telescopic tube includes an upper sleeve and a lower sleeve. The upper end of the upper sleeve is fixed to the top plate. The upper sleeve is a hollow tube with an annular space on its inner wall. The lower end of the annular space is open. The lower sleeve is slidably assembled in the annular space, which contains an elastic element.

[0011] Based on the above scheme, the following improvements are made: the elastic expansion tube is an elastic corrugated tube.

[0012] The technical solution of the beverage bottle of the present invention is as follows: The beverage bottle includes a bottle body and a bottle cap with threaded engagement; a sealing film is affixed to the upper rim of the bottle body; and the bottle cap includes:

[0013] The cover includes a top plate and a surrounding plate, the surrounding plate having internal threads;

[0014] Spikes are located inside the cover and on the top plate;

[0015] The dynamic sealing assembly includes an elastic telescopic tube that can elastically expand and contract along its axial direction. The upper end of the elastic telescopic tube is fixedly connected to a top plate, and the lower end of the elastic telescopic tube has an annular sealing part. The lower surface of the annular sealing part is sealed and fitted to the upper opening of the bottle. The elastic telescopic tube, the spikes, and the sealing film form a receiving cavity for accommodating solid additives.

[0016] Based on the above scheme, the following improvements are made: the elastic telescopic tube includes at least two telescopic sleeves and an elastic element that provides elastic force to the telescopic sleeves in the extension direction.

[0017] Based on the above scheme, further improvements are made as follows: the elastic telescopic tube includes an upper sleeve and a lower sleeve. The upper end of the upper sleeve is fixed to the top plate. The upper sleeve is a hollow tube with an annular space on its inner wall. The lower end of the annular space is open. The lower sleeve is slidably assembled in the annular space, which contains an elastic element.

[0018] Based on the above scheme, the following improvements are made: the elastic expansion tube is an elastic corrugated tube.

[0019] The beneficial effects of this application are as follows: When the beverage bottle and its cap are in use, initially, the bottle contains pure water and the upper rim is sealed by a sealing film. The cap is screwed onto the bottle, and the spikes do not contact the sealing film. The solid additive is located in the cavity between the elastic expansion tube, the spikes, and the sealing film. When the user wants to drink, they simply screw on the cap, causing the spikes to pierce the sealing film. During the screwing process, the lower annular sealing part of the elastic expansion tube of the dynamic sealing component is in constant contact with the upper rim of the bottle. As the spikes pierce the sealing film, the elastic expansion tube is gradually compressed, and the annular sealing part slides and seals with the upper rim of the bottle, preventing the liquid inside the bottle from flowing out through the gap at the contact point. This achieves a dynamic sealing effect, ensuring that the liquid does not leak between the cap and the bottle when the user inverts the beverage bottle later. Moreover, there is no limit to the number of turns the cap can be screwed on during the entire operation. It is convenient to use. After the pure water that has entered the cap has fully dissolved the solid additive, the cap can be unscrewed and the beverage can be drunk directly. Therefore, this application can maintain a continuous seal between the cap and the bottle opening throughout the entire process of twisting the cap to pierce the sealing film and inverting the beverage bottle. Before mixing by inverting, there is no need to twist the cap to the bottom, thereby improving the convenience of use. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0027] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0029] Example 1 of the beverage bottle of the present invention: as follows Figure 1-2 As shown, the beverage bottle includes a threaded bottle body 1 and a bottle cap 2. A sealing film 3 is attached to the upper edge of the bottle body 1, and the bottle cap 2 includes a cap body, a spike 24, and a dynamic sealing component 25.

[0030] The cover includes a top plate 21 and a surrounding plate 22, the surrounding plate 22 having an internal thread 23; spikes 24 are located inside the cover and are provided on the top plate 21.

[0031] The dynamic sealing assembly 25 includes an elastic telescopic tube that can elastically extend and retract along its axial direction. The upper end of the elastic telescopic tube is fixedly connected to the top plate 21, and the lower end of the elastic telescopic tube has an annular sealing part 2521. The lower surface of the annular sealing part 2521 is in sealing contact with the upper opening of the bottle body 1. The elastic telescopic tube, the spike 24, and the sealing membrane 3 form a receiving cavity for receiving the solid additive 4. The elastic telescopic tube includes at least two telescopic sleeves and an elastic element 2512 that provides elastic force to the telescopic sleeves in the extension direction. The elastic telescopic tube includes an upper sleeve 251 and a lower sleeve 252. The upper end of the upper sleeve 251 is fixed to the top plate 21. The upper sleeve 251 is a hollow tube with an annular space 2511 on its inner wall. The lower end of the annular space 2511 is open. The lower sleeve 252 is slidably assembled in the annular space 2511, and the annular space 2511 contains the elastic element 2512. In this embodiment, the bottle cap 2, the spike 24, and the dynamic sealing assembly 25 are all made of the same plastic material and can be manufactured as a single piece.

[0032] In Example 2, as Figure 3 As shown, the elastic telescopic tube is an elastic corrugated tube 253.

[0033] When the beverage bottle and its cap 2 are in use, initially, the bottle body 1 contains pure water, and the upper rim is sealed by the sealing film 3. The cap 2 is screwed onto the bottle body 1, and the spike 24 does not contact the sealing film 3. The solid additive 4 is located in the cavity between the elastic telescopic tube, the spike 24, and the sealing film 3. When the user wants to drink, they directly screw on the cap 2, causing the spike 24 to pierce the sealing film 3. During the screwing process, the lower annular sealing part 2521 of the elastic telescopic tube of the dynamic sealing assembly 25 is constantly in contact with the upper rim of the bottle body 1. The spike 24 pierces the sealing film 3, gradually compressing the elastic telescopic tube. The annular sealing part 2521 slides and seals with the upper edge of the bottle body 1, preventing liquid from flowing out through the gap at the contact point, thus achieving a dynamic seal effect. This ensures that when the user inverts the beverage bottle later, liquid will not leak between the cap 2 and the bottle body 1. Moreover, there is no limit to the number of turns the cap 2 can be turned during the entire operation, making it convenient to use. After the pure water entering the cap 2 has fully dissolved the solid additive 4, the cap 2 can be unscrewed and the beverage can be consumed directly. Therefore, this application can maintain a continuous seal between the cap 2 and the bottle mouth throughout the process of screwing the cap 2 to pierce the sealing film 3 and inverting the beverage bottle. Before inverting and mixing, there is no need to screw the cap 2 to the bottom, thereby improving the convenience of use.

[0034] Example 3 of the beverage bottle of the present invention: as follows Figure 4As shown, the difference from Embodiment 1 is that a dedicated elastic element is no longer provided. Instead, the elastic force is achieved by utilizing the conical structure of the upper sleeve 151 and the lower sleeve 252. Specifically, the annular space of the upper sleeve 151 is a conical structure that is larger at the bottom and smaller at the top. Correspondingly, the upper end of the lower sleeve 252 is also a matching conical structure. When the lower sleeve 252 and the upper sleeve 151 are relatively close, the clamping force provided by the upper sleeve 151 is applied to the lower sleeve 252. On the one hand, it provides the lower sleeve 252 with an elastic force in the direction away from the upper sleeve 151, so as to ensure that the annular sealing part 2521 at the bottom of the lower sleeve 252 can be elastically pressed against the upper edge of the bottle. On the other hand, the conical surface provides a two-stage seal, improves the sealing performance, and avoids liquid leakage.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
