Description

Technical Field

[0001] This application relates to the field of food packaging technology, and more particularly to a bottle cap and a bottle. Background Technology

[0002] Bottled beverages are very popular among consumers, as they can be consumed directly after opening the bottle, making them very convenient and quick.

[0003] Bottled beverage bottles typically consist of a bottle body and a cap, connected by threads. During production, the beverage is first prepared and poured into the bottle body, then the cap is screwed onto the bottle opening, thus sealing the prepared beverage within the bottle. To drink, simply unscrew the cap.

[0004] However, for some beverages containing nutrients or active ingredients, such as vitamins and probiotics, if the existing bottled beverage packaging is used to fill the liquid beverage containing nutrients or active ingredients into the bottle, the nutrients in the beverage will decompose due to factors such as storage time and light, which will affect the taste of the beverage and reduce its shelf life, or the active ingredients may easily lose their activity. Summary of the Invention

[0005] Based on this, this application provides a bottle cap and a bottle, the bottle cap of which can improve the taste and shelf life of beverages.

[0006] In a first aspect, this application provides a bottle cap, which includes an upper cap, a middle cap, and a lower cap. The lower cap is used to connect with the bottle body, and the upper cap is connected with the lower cap to seal the bottle body. The upper cap and the lower cap together form an installation cavity. The middle cap is located in the installation cavity and has a receiving groove for receiving basic raw materials. The installation cavity has a cutting element. The upper cap and the middle cap can rotate synchronously relative to the lower cap, and the cutting element cuts the middle cap to connect the receiving groove with the bottle body.

[0007] In one possible implementation, the bottle cap provided in this application includes a middle cap body and a sealing element, with a receiving groove located within the middle cap body, the opening of the receiving groove facing the upper cap, and the sealing element covering the opening to seal the receiving groove.

[0008] In one possible implementation, the bottle cap provided in this application has a protrusion on the side of the middle cap body facing away from the upper cap, and the side of the protrusion has a non-cutting part and a cutting part, which are connected. The cutting part is opposite to the cutting part, and when the middle cap rotates relative to the lower cap, the cutting part cuts the cutting part.

[0009] In one possible implementation, the bottle cap provided in this application includes a first lower cap body and a second lower cap body. The first lower cap body and the second lower cap body are coaxially connected. The first lower cap body is inserted into the upper cap, and the inner sidewall of the first lower cap body and the inner sidewall of the upper cap together form an installation cavity. The second lower cap body is used to connect with the bottle body.

[0010] The inner wall of the first lower cover body and the outer wall of the middle cover body have two positioning blocks, and the other has a stop block. When the middle cover rotates, the stop block abuts against one of the two positioning blocks respectively.

[0011] In one possible implementation, the bottle cap provided in this application has a retaining ring on the inner wall of the first lower cap body, and the cutting element is cut into the inner wall of the retaining ring.

[0012] The side of the middle cover that faces away from the top cover abuts against the retaining ring, with the protruding part located inside the retaining ring.

[0013] In one possible implementation, the bottle cap provided by this application has a straight non-cut portion and an arc-shaped cut portion, and the distance between the two positioning blocks is greater than or equal to the length of the non-cut portion.

[0014] In one possible implementation, the bottle cap provided in this application has at least one snap-fit ​​groove on one of the inner side wall of the top cap and the outer side wall of the middle cap body, and at least one snap-fit ​​part on the other, with the snap-fit ​​part and the snap-fit ​​groove corresponding to each other.

[0015] In one possible implementation, the bottle cap provided in this application has an inner wall of the upper cap with a first internal thread and an outer wall of the lower cap body with a first external thread, the first external thread engaging with the first internal thread.

[0016] In one possible implementation, the bottle cap provided in this application has a first connecting portion on the inner side wall of the first lower cap body, which is used to connect with a second connecting portion of the bottle body.

[0017] In one possible implementation, the bottle cap provided in this application has a first connecting part with a second internal thread and a second connecting part with a second external thread;

[0018] Alternatively, one of the first connecting part and the second connecting part may be a slot, and the other may be a buckle that matches the slot.

[0019] In one possible implementation, the bottle cap provided in this application further includes an anti-reverse component, which includes a first anti-reverse member and a second anti-reverse member. The first anti-reverse member is located on the inner side wall of the upper cap, and the second anti-reverse member is located on the outer side wall of the first lower cap body. The first anti-reverse member and the second anti-reverse member abut against each other to prevent the upper cap from reversing relative to the lower cap.

[0020] In one possible implementation, the bottle cap provided in this application further includes an anti-theft component, which includes a positioning groove and a stop tooth.

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0044] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0045] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0046] Bottled beverage bottles typically consist of a bottle body and a cap, connected by threads. During production, the beverage is first prepared and poured into the bottle body, then the cap is screwed onto the bottle opening, thus sealing the prepared beverage within the bottle. To drink, simply unscrew the cap.

[0047] However, for some beverages containing nutrients or active ingredients, such as vitamins and probiotics, if the existing bottled beverage packaging is used to fill the liquid beverage containing nutrients or active ingredients into the bottle, the nutrients in the beverage will decompose due to factors such as storage time and light, which will affect the taste of the beverage and reduce its shelf life, or the active ingredients may easily lose their activity.

[0048] Alternatively, a bottle cap with a separate, sealed storage space can be used to seal the base ingredients within this space. The base ingredients are then placed into the bottle before consumption. This type of bottle cap with a separate, sealed storage space mainly consists of an upper cap and a lower cap. When the upper and lower caps are connected, the cavity is usually sealed using a heat-sealing method. Since both the upper and lower caps are made of plastic, they can release harmful gases at high temperatures, which can contaminate the base ingredients and compromise their food safety.

[0049] Based on this, this application provides a bottle cap and a bottle, the bottle cap of which can improve the taste and shelf life of bottled beverages.

[0050] The bottle cap and bottle of this embodiment will be described in detail below with reference to the accompanying drawings.

[0051] Figure 1 This is a schematic diagram of the bottle structure provided in an embodiment of this application. (Refer to...) Figure 1 As shown in the figure, this application embodiment provides a bottle, which includes a bottle body 20 and a bottle cap 10 connected to the bottle body 20.

[0052] The bottle can be a standard-diameter PET bottle, a can, or other container. The bottle body 20 is used to hold the base solution, and the cap 10 can be connected to the bottle body 20 by means of threads or snaps to seal the bottle body 20.

[0053] Figure 2 This is a schematic diagram of the structure of the bottle cap provided in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of the middle cap in the bottle cap provided in the embodiments of this application; Figure 4 This is a schematic diagram of the structure of the lower cap in the bottle cap provided in an embodiment of this application; Figure 5 for Figure 4 A top view. (Refer to...) Figures 2 to 5 As shown, the bottle cap 10 provided in this embodiment includes an upper cap 100, a middle cap 200, and a lower cap 300. The lower cap 300 is used to connect with the bottle body 20. The upper cap 100 is connected with the lower cap 300 to seal the bottle body 20. The upper cap 100 and the lower cap 300 together form an installation cavity. The middle cap 200 is located in the installation cavity and has a receiving groove for receiving basic raw materials. The installation cavity has a cutting element 400. The upper cap 100 and the middle cap 200 can rotate synchronously relative to the lower cap 300, and the cutting element 400 cuts the middle cap 200 to connect the receiving groove and the bottle body 20.

[0054] In this application, the lower cover 300 has openings at both ends, the upper cover 100 has an opening at one end, and the other end of the upper cover 100 is closed. The lower cover 300 is used to connect with the bottle body 20 so that the bottle cap 10 is fixed to the bottle body 20. The upper cover 100 is connected with the lower cover 300 to close the opening of the lower cover 300, thereby sealing the bottle body 20. The middle cover 200 is located in the mounting cavity formed by the upper cover 100 and the lower cover 300. The middle cover 200 is used to hold the base material and seal the base material in the receiving groove of the middle cover 200 to prevent the base material from contacting the outside air and deteriorating. Thus, the middle cover 200 can serve as a sealing component for the base material. The middle cover 200 can independently fill and seal the base material, and the middle cover 200 has good sealing performance.

[0055] When needed, the top cover 100 and the middle cover 200 can be rotated synchronously, causing the cutting element 400 to cut the middle cover 200, thereby connecting the receiving groove with the bottle body 20. This allows the base material to enter the bottle body 20 and mix with the base solution inside. The cooperation of the top cover 100, middle cover 200, and bottom cover 300 ensures the base material smoothly enters the bottle body 20 and mixes with the base solution. Before mixing, the base material is relatively stable within the dry and sealed middle cover 200, making it less prone to spoilage, thus extending the shelf life of the bottled beverage. Furthermore, immediate consumption after mixing enhances the taste of the bottled beverage. After consumption, the user can remove the middle cover 200 from the mounting cavity for bottle reuse.

[0056] In the production of the bottle cap 10 of this embodiment, the basic raw material can be pre-filled and sealed in the middle cap 200. Subsequently, only the middle cap 200, the upper cap 100, and the lower cap 300 need to be assembled. Therefore, filling the bottle cap 10 with the basic raw material is convenient. Furthermore, different basic raw materials can be filled in different middle caps 200 as needed to form a variety of different middle caps 200. Then, the upper cap 100 and the lower cap 300 are connected to the different middle caps 200 to form bottle caps 10 containing different basic raw materials. The bottle caps 10 filled with different basic raw materials are then connected to the bottle body 20 filled with the same basic solution to form different bottled beverages.

[0057] Understandably, to ensure the safety of the basic raw materials, the basic raw materials can be filled into the middle cover 200 and sealed in a sterile production environment, and the upper cover 100, middle cover 200 and lower cover 300 can be assembled in a normal production environment.

[0058] The basic raw materials can be beverage concentrates, effervescent tablets, protein powder, coffee powder, and probiotics, while the basic solution can be water.

[0059] The bottle cap 10 provided in this embodiment of the application has a lower cap 300 for connecting to the bottle body 20, an upper cap 100 on the lower cap 300 for sealing the bottle body 20, and a middle cap 200 for filling and sealing the base material. This facilitates the filling of the bottle cap 10 with the base material and improves the shelf life of the bottled beverage. Furthermore, various middle caps 200 containing different base materials can be formed as needed, resulting in different bottle caps 10. When needed, the upper cap 100 and the middle cap 200 are rotated synchronously relative to the lower cap 300, causing the cutting element 400 to cut the middle cap 200, allowing the base material to enter the bottle body 20 and mix with the base solution. Then, the lower cap 300 is separated from the bottle body 20, opening the bottle cap 10, allowing the user to immediately drink the mixed beverage with a better taste. Therefore, the bottle cap 10 can improve the taste and shelf life of bottled beverages.

[0060] Reference Figure 3 As shown, in a specific implementation, the middle cover 200 includes a middle cover body 210 and a sealing member 220. The receiving groove is located inside the middle cover body 210, and the opening of the receiving groove faces the upper cover 100. The sealing member 220 covers the opening to seal the receiving groove.

[0061] When filling the base material, the base material can enter the receiving tank through the slot opening, and then the sealing element 220 is placed on the slot opening of the receiving tank. Finally, the sealing element 220 is connected to the middle cover body 210 to seal the receiving tank, so as to prevent the base material inside the middle cover 200 from oxidizing and deteriorating.

[0062] The sealing element 220 can be a sealing film, which can be connected to the middle cover body 210 by thermoplastic or ultrasonic welding. This embodiment does not limit this. When the sealing element 220 is connected to the middle cover body 210, it will not produce harmful gases.

[0063] Figure 6 for Figure 3 A bottom view. (Refer to...) Figure 3 and Figure 6 As shown, in some embodiments, the middle cover body 210 has a protrusion 230 on the side opposite to the upper cover 100. The side of the protrusion 230 has a non-cutting portion 231 and a cutting portion 232. The non-cutting portion 231 and the cutting portion 232 are connected. The cutting member 400 is opposite to the cutting portion 232. When the middle cover 200 rotates relative to the lower cover 300, the cutting member 400 cuts the cutting portion 232.

[0064] When the bottle is placed vertically, the bottom of the middle cap body 210 has a protrusion 230, and the side of the protrusion 230 has a cutting part 232 and a non-cutting part 231. When the user needs to pour the base material in the middle cap 200 into the bottle body 20, the upper cap 100 can be rotated so that the upper cap 100 and the middle cap 200 can rotate synchronously relative to the lower cap 300. During the rotation, the blade of the cutting piece 400 sequentially cuts through the cutting part 232, thereby cutting the cutting part 232 and breaking the bottom of the middle cap body 210, so that the base material falls into the bottle body 20 and mixes with the base solution. The non-cutting part 231 will not be cut to prevent the protrusion 230 from falling into the bottle body 20.

[0065] Alternatively, users can choose to drink the base solution directly. In this case, users can directly rotate the lower cap 300 to separate the cap 10 from the bottle body 20.

[0066] Reference Figure 2 and Figure 4As shown, in a specific implementation, the lower cover 300 includes a first lower cover body 310 and a second lower cover body 320. The first lower cover body 310 and the second lower cover body 320 are coaxially connected. The first lower cover body 310 is inserted into the upper cover 100, and the inner sidewall of the first lower cover body 310 and the inner sidewall of the upper cover 100 together form an installation cavity. The second lower cover body 320 is used to connect with the bottle body 20.

[0067] The first lower cap body 310 is inserted into the upper cap 100 and can be fixedly connected to the upper cap 100 and the first lower cap body 310 by means of threaded connection or snap-fit ​​connection. The second lower cap body 320 can be fixedly connected to the bottle body 20 by means of threaded connection or snap-fit ​​connection. That is, even when the bottle cap 10 does not have a middle cap 200, the upper cap 100 and the lower cap 300 can still be well connected and sealed to the bottle body 20. After the bottled beverage in the bottle is consumed, the user can remove the middle cap 200 to reuse the bottle. Therefore, the bottle cap 10 has a wide range of applications.

[0068] Reference Figures 3 to 5 As shown, one of the inner wall of the first lower cover body 310 and the outer wall of the middle cover body 210 has two positioning blocks 311, and the other has a stop block 211. When the middle cover 200 rotates, the stop block 211 abuts against one of the two positioning blocks 311. In this way, through the cooperation of the positioning block 311 and the stop block 211, the cutting part 400 can accurately cut the cutting part 232 without cutting the non-cutting part 231.

[0069] For example, at the starting position of the rotation of the middle cover 200, the stop block 211 abuts against a positioning block 311. The middle cover 200 rotates, and the cutting part 400 cuts the cutting part 232 in sequence until the stop block 211 abuts against another positioning block 311. This indicates that the cutting part 232 has been cut in place. At this time, the user can shake the bottle and then open the bottle cap 10 to drink the mixed beverage.

[0070] Reference Figure 3 , Figure 5 and Figure 6 As shown, in a specific implementation, the inner wall of the first lower cover body 310 has a retaining ring 312, the cutting part 400 is located on the inner wall of the retaining ring 312, the side of the middle cover body 210 facing away from the upper cover 100 abuts against the retaining ring 312, and the protrusion 230 part is located inside the retaining ring 312, that is, the cutting part 232 and the non-cutting part 231 are located inside the retaining ring 312.

[0071] Therefore, when the cover 200 rotates, the protrusion 230 can rotate relative to the retaining ring 312, so that the cutting edge of the cutting piece 400 passes through the side of the protrusion 230 in sequence, thereby cutting the cutting part 232.

[0072] In one possible implementation, the non-cutting portion 231 is straight, the cutting portion 232 is arc-shaped, and the distance between the two positioning blocks 311 is greater than or equal to the length of the non-cutting portion 231.

[0073] In this way, the side of the middle cover body 210 facing away from the upper cover 100 is D-shaped. When the middle cover 200 rotates from the position where the stop block 211 abuts against one positioning block 311 to the position where the stop block 211 abuts against another positioning block 311, the cutting part 400 can only cut the cutting part 232 and will not cut the non-cutting part 231, ensuring that the protrusion 230 will not be completely cut open, so as to prevent the protrusion 230 from falling into the bottle body 20.

[0074] Understandably, when the distance between the two positioning blocks 311 is equal to the length of the non-cutting portion 231, the cutting element 400 completely cuts off the cutting portion 232, while the non-cutting portion 231 remains connected to the middle cover body 210. When the distance between the two positioning blocks 311 is greater than the length of the non-cutting portion 231, the cutting element 400 cuts off a portion of the cutting portion 232, while the other portion of the cutting portion 232 and the non-cutting portion 231 remain connected to the middle cover body 210.

[0075] Figure 7 This is a schematic diagram of the structure of the upper cap in a bottle cap provided in an embodiment of this application. (Refer to...) Figure 3 and Figure 7 As shown, in some embodiments, one of the inner wall of the upper cover 100 and the outer wall of the middle cover body 210 has at least one snap-fit ​​groove 212, and the other has at least one snap-fit ​​portion 110, with the snap-fit ​​portion 110 corresponding to the snap-fit ​​groove 212. Thus, the middle cover 200 and the upper cover 100, as well as the middle cover 200 and the lower cover 300, are detachably connected. The middle cover 200 can be filled and sealed separately with basic materials before being connected to the upper cover 100 and the lower cover 300 to secure it within the mounting cavity. After the beverage in the bottle is consumed, the user can easily remove the middle cover 200 from the mounting cavity.

[0076] For example, the inner wall of the upper cover 100 has one or more snap-fit ​​grooves 212, and the outer wall of the middle cover body 210 has snap-fit ​​parts 110 corresponding to the snap-fit ​​grooves 212. By snapping the snap-fit ​​parts 110 with the snap-fit ​​grooves 212, the upper cover 100 and the middle cover body 210 are connected. Thus, when the upper cover 100 is rotated, the middle cover 200 and the upper cover 100 can rotate synchronously relative to the lower cover 300.

[0077] Alternatively, the outer side wall of the middle cover body 210 has one or more snap-fit ​​grooves 212, and the inner side wall of the upper cover 100 has snap-fit ​​parts 110. The snap-fit ​​parts 110 and the snap-fit ​​grooves 212 are snapped together one by one, thereby connecting the upper cover 100 and the middle cover body 210, so that the middle cover 200 and the upper cover 100 can rotate synchronously relative to the lower cover 300.

[0078] Reference Figure 4 and Figure 7 As shown, in some embodiments, the inner wall of the upper cover 100 has a first internal thread 120, and the outer wall of the first lower cover body 310 has a first external thread 313. The first external thread 313 engages with the first internal thread 120, thereby fixing the upper cover 100 and the first lower cover body 310 together.

[0079] Reference Figure 1 and Figure 4 As shown, in one optional embodiment, the inner wall of the first lower cap body 310 has a first connecting portion 321, which is used to connect with the second connecting portion 21 of the bottle body 20. Thus, by connecting the first connecting portion 321 and the second connecting portion 21, the first lower cap body 310 can be connected to the bottle cap 10, thereby connecting the bottle cap 10 to the bottle body 20.

[0080] It should be understood that in some embodiments, the first connecting part 321 is a second internal thread and the second connecting part 21 is a second external thread. The first lower cover body 310 is connected to the bottle body 20 through the connection between the second internal thread and the second external thread, thereby connecting the bottle cap 10 to the bottle body 20.

[0081] Alternatively, in some other embodiments, one of the first connecting part 321 and the second connecting part 21 is a slot, and the other is a buckle that matches the slot. The first lower cover body 310 is connected to the bottle body 20 by the buckle engaging in the slot, thereby connecting the bottle cap 10 to the bottle body 20.

[0082] Reference Figure 4 and Figure 7 As shown, in one possible implementation, the bottle cap 10 provided in this application embodiment further includes an anti-reverse component. The anti-reverse component includes a first anti-reverse member 130 and a second anti-reverse member 314. The first anti-reverse member 130 is located on the inner side wall of the upper cap 100, and the second anti-reverse member 314 is located on the outer side wall of the first lower cap body 310. The first anti-reverse member 130 and the second anti-reverse member 314 abut against each other to prevent the upper cap 100 from reversing relative to the lower cap 300.

[0083] For example, the top cap 100 and the middle cap 200 can rotate clockwise relative to the bottom cap 300 simultaneously, causing the cutting element 400 to cut the cutting section 232, thus allowing the base material to fall into the bottle body 20. The bottle is then shaken to ensure the base material and base solution are evenly mixed. Afterward, the bottom cap 300 is rotated counterclockwise relative to the bottle body 20, causing it to separate from the bottle body 20, allowing the user to drink the mixed solution inside the bottle body 20. During the counterclockwise rotation of the bottom cap 300, an anti-reverse component prevents the top cap 100 from rotating counterclockwise relative to the bottom cap 300, ensuring that both the top cap 100 and the bottom cap 300 rotate counterclockwise relative to the bottle body 20 until the cap 10 separates from the bottle body 20.

[0084] Alternatively, the upper cap 100 and the middle cap 200 can rotate counterclockwise relative to the lower cap 300 simultaneously to allow the cutting element 400 to cut the cutting portion 232. Then, the lower cap 300 can be rotated clockwise to separate it from the bottle body 20. When the lower cap 300 is rotated clockwise, the anti-reverse component prevents the upper cap 100 from rotating clockwise relative to the lower cap 300, thereby allowing the upper cap 100 and the lower cap 300 to rotate clockwise relative to the bottle body 20 simultaneously until the cap 10 separates from the bottle body 20.

[0085] Continue to refer to Figure 4 and Figure 7 As shown, in order to identify whether the top cover 100 has been opened, the bottle cap 10 provided in this application embodiment also includes an anti-theft component. The anti-theft component includes a positioning groove 140 and a stop tooth 322. The positioning groove 140 is located on one of the inner side wall of the top cover 100 and the outer side wall of the second bottom cover body 320, and the stop tooth 322 is located on the other of the inner side wall of the top cover 100 and the outer side wall of the second bottom cover body 320. The stop tooth 322 is inserted into the positioning groove 140.

[0086] For example, the inner wall of the upper cover 100 has a positioning groove 140, and the outer wall of the second lower cover body 320 has a retaining tooth 322, which is inserted into the positioning groove 140. If the position of the retaining tooth 322 relative to the positioning groove 140 changes, it indicates that the upper cover 100 has rotated relative to the lower cover 300, and the upper cover 100 has been opened. If the position of the retaining tooth 322 relative to the positioning groove 140 does not change, it indicates that the upper cover 100 has not rotated relative to the lower cover 300, and the upper cover 100 has not been opened. Thus, the user can quickly identify whether the upper cover 100 has been opened by observing the relative positions of the positioning groove 140 and the retaining tooth 322.

[0087] Alternatively, the inner wall of the upper cover 100 has a stop tooth 322, and the outer wall of the second lower cover body 320 has a positioning groove 140. The stop tooth 322 is inserted into the positioning groove 140. The user can quickly identify whether the upper cover 100 has been opened by observing the relative position of the positioning groove 140 and the stop tooth 322.
