Description

Technical Field

[0001] The present application relates to the technical field of drinking bottles, and in particular to a bottle cap and a drinking bottle. Background Art

[0002] According to a lot of market research conducted by the applicant, many beverages on the market are already mixed with additives, such as chrysanthemum tea. For these beverages, in order to ensure that they do not deteriorate, a large amount of preservatives and other additives are added to the beverages. When users need to drink, these beverages will have an adverse effect on their health. Another example is medicated diet beverages. For these beverages, since medicinal diet plants are easily spoiled when directly added to water, a large amount of additives must be added to the beverages. In this way, after a long period of light exposure, many medicinal ingredients will be decomposed, destroyed, and even produce toxic substances. When users need to drink, it will have a certain impact on their health. Therefore, it is particularly important to provide a drinking bottle that is not easy to have an adverse effect on the user's health. Utility Model Content

[0003] The present application provides a bottle cap and a drinking bottle which are not likely to have adverse effects on the health of users.

[0004] In a first aspect, the present application provides a bottle cap. The bottle cap comprises a cap body, an additive and an easy-tear film;

[0005] The cover body includes a top plate portion, a frame portion and a receiving portion, the top plate portion includes a top surface and a bottom surface arranged in a back direction, the frame portion is fixed to the bottom surface of the top plate portion, and the frame portion and the top plate portion enclose a first space;

[0006] The accommodating portion is fixed to the bottom surface of the top plate portion, at least part of the accommodating portion is located in the first space, the accommodating portion surrounds the second space, the top plate portion is provided with a through hole, the through hole runs from the top surface of the top plate portion to the bottom surface of the top plate portion, and the through hole is connected to the second space;

[0007] The easy-tear film is fixed on the top surface of the top plate, and the easy-tear film seals the through hole and the second space;

[0008] The additive is located in the second space.

[0009] It is understandable that when the bottle cap is applied to a drinking bottle, if the user needs to drink, the bottle cap of the drinking bottle can be removed from the bottle body first. Then the tear film can be torn off from the cap body. Finally, the additive in the second space is poured into the liquid in the bottle body, and it can be drunk after being fully stirred. Of course, the tear film can also be torn off first, and then the bottle cap of the drinking bottle can be removed from the bottle body. The specific operation can be based on the user's habits. This application is not limited.

[0010] For example, when the additive is dried chrysanthemum, dried lotus, dried honeysuckle, dried mint or dried rose, after the dried chrysanthemum, dried lotus, dried honeysuckle, dried mint or dried rose is poured into the liquid in the bottle, it can be directly consumed after waiting for a while. Of course, it can also be heated and brewed before drinking.

[0011] Compared with beverages on the market, many beverages are already mixed with additives, such as chrysanthemum tea. For these beverages, in order to ensure that they do not deteriorate, a large amount of additives such as preservatives are added to the beverages. When users need to drink, it will have an adverse effect on their health. Another example is medicated beverages. For these beverages, since solid plants of medicated diet are directly added to water, it is easy to deteriorate, so a large amount of additives must be added to the beverages. In this way, after a long period of light exposure, many medicinal ingredients will be decomposed, destroyed, and even produce toxic substances. When users need to drink, it will have a certain impact on their health. In this embodiment, by additionally arranging a second space and an easy-to-tear film on the cover body, and arranging the additive in the second space, the liquid and additive of the drinking bottle can be arranged separately. In this way, when the user needs to drink, the additive is taken out and poured into the liquid of the bottle body, and it can be drunk after being fully stirred. At this time, the liquid in the bottle body does not need to be added with a large amount of preservatives or other additives, ensuring that the liquid will not have an adverse effect on health.

[0012] It can be understood that compared with the solution of setting the easy-tear film inside the bottle body, this embodiment sets the easy-tear film on the outside of the bottle body. On the one hand, the easy-tear film is not easy to contaminate the liquid due to being soaked in the liquid in the bottle body, and on the other hand, the easy-tear film will not be difficult to tear off due to being soaked in the liquid.

[0013] It is understandable that when the bottle cap is mounted on the bottle body, the receiving portion can be located inside the bottle body. In this case, the shape of the receiving portion will not affect the appearance of the drinking bottle. In this way, the appearance of the drinking bottle is better. In addition, since the receiving portion can be located inside the bottle body, the receiving portion can be free from impact by external objects. In this way, the wall thickness of the receiving portion can be reduced to a large extent. In this case, the bottle cap can reduce the material cost of production to a large extent. In addition, the bottle cap can also be easier to produce and process.

[0014] In a possible implementation manner, the top plate portion is provided with a receiving groove, the receiving groove forms an opening on the top surface of the top plate portion, the receiving groove is connected to the through hole, and the easy-tear film is fixed in the receiving groove.

[0015] In a possible implementation manner, the top surface of the easy-tear film is flush with the top surface of the top plate portion, or the top surface of the easy-tear film is located in the accommodating groove.

[0016] In a possible implementation manner, the distance between the bottom surface of the accommodating portion and the top surface of the top plate portion is a first height, and the bottom surface of the accommodating portion is a surface of the accommodating portion away from the top plate portion;

[0017] The distance between the bottom surface of the frame portion and the top surface of the top plate portion is a second height, the second height is less than or equal to the first height, and the bottom surface of the frame portion is a surface of the frame portion away from the top plate portion.

[0018] In a possible implementation manner, the first height is in a range of 13 mm to 50 mm, and / or the second height is in a range of 10 mm to 15 mm.

[0019] In a possible implementation manner, a cross-sectional shape of an outer side surface of the accommodation portion is circular, elliptical, trapezoidal, triangular, or polygonal.

[0020] In a possible implementation manner, the outer side surface of the frame portion is provided with a plurality of grooves, and / or the outer side surface of the frame portion is provided with a plurality of protrusions.

[0021] In a possible implementation manner, the accommodating portion is connected to a middle portion of the top plate portion.

[0022] In a possible implementation manner, the cover body further includes a partition, the partition is located in the second space, the partition is connected to the accommodating portion, and the partition divides the second space into a plurality of sub-spaces;

[0023] The additive includes a plurality of sub-additives, and the plurality of sub-additives are arranged in a one-to-one correspondence in a plurality of the sub-spaces.

[0024] In a possible implementation, the additive includes a powdered edible additive, a liquid edible additive, a freeze-dried edible additive, or a sheet-like edible additive.

[0025] Exemplarily, the powdered edible additives include chrysanthemum powder, lotus powder, honeysuckle powder, mint powder, rose powder, tea powder, and the like.

[0026] Exemplarily, the liquid edible additives include ointments, honey, inorganic salt electrolytes, and the like.

[0027] Exemplarily, freeze-dried edible additives include dried chrysanthemum, dried lotus, dried honeysuckle, dried mint, dried rose, etc.

[0028] Exemplarily, the sheet-like edible additives include VC effervescent tablets and the like.

[0029] In other embodiments, the additives may also be other gifts or printed products, or lottery tickets, similar to scratch cards, or blind box toys, to increase the pleasure attribute of the beverage.

[0030] In one embodiment, the bottle cap further comprises a capsule, and the additive is arranged in the capsule.

[0031] It is understandable that, compared with the solution of placing additives directly in the second space, by placing the additives in the capsule, on the one hand, the additives are relatively clean and simple and not easily contaminated, and on the other hand, the additives will not be scattered or remain in the second space to avoid being scattered. It is understandable that the capsule can be made of animal and plant pectin, which is a natural ingredient and easily soluble in water. In this way, when the user needs to drink liquid, after opening the easy-tear film, the capsule is directly placed in the liquid. After the capsule dissolves, the additive can be dissolved in the liquid.

[0032] In a second aspect, the present application provides a drinking bottle, which comprises a bottle body and the bottle cap as described above, wherein the bottle mouth of the bottle body is installed in the first space of the bottle cap, and the receiving portion of the cap is located inside the bottle body.

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0044] Figure 1 A schematic structural diagram of an implementation manner of a drinking bottle 100 provided in an embodiment of the present application.

[0045] like Figure 1 As shown, the present application provides a drinking bottle 100. The drinking bottle 100 can be a bottle that can contain liquid, such as a mineral water bottle, a beverage bottle, a wine bottle, etc.

[0046] Figure 2 yes Figure 1 A partially exploded schematic diagram of an embodiment of a drinking bottle 100 is shown. Figure 3 yes Figure 2 The bottle cap 20 shown is a schematic structural diagram at another angle.

[0047] like Figures 1 to 3As shown, the drinking bottle 100 includes a bottle body 10 and a bottle cap 20, and the bottle cap 20 is installed on the bottle body 10. The bottle body 10 can be used to bottle liquid. For example, the liquid can be drinkable liquids such as water, beverages, wine, soup, etc.

[0048] Exemplarily, the bottle mouth 11 of the bottle body 10 is provided with an external thread 111. The bottle cap 20 is provided with an internal thread 201. Through the cooperation of the external thread 111 and the internal thread 201, the bottle cap 20 can be threadedly connected to the bottle body 10.

[0049] Figure 4 yes Figure 3 The bottle cap 20 is shown as a schematic structural diagram at another angle. Figure 5 yes Figure 4 The bottle cap 20 is shown in an exploded schematic diagram in one embodiment.

[0050] like Figure 4 and Figure 5 As shown, the bottle cap 20 includes a cap body 21, an additive 22 and an easy-tear film 23. It can be understood that Figure 4 and Figure 5 The additives 22 are schematically shown by rectangular frames. The structure, size and shape of the additives 22 are not specifically limited.

[0051] In a possible implementation, the additive 22 includes a powdered edible additive, a liquid edible additive, a freeze-dried edible additive, or a sheet-like edible additive.

[0052] Exemplarily, the powdered edible additives include chrysanthemum powder, lotus powder, honeysuckle powder, mint powder, rose powder, tea powder, and the like.

[0053] Exemplarily, the liquid edible additives include ointments, honey, inorganic salt electrolytes, and the like.

[0054] Exemplarily, freeze-dried edible additives include dried chrysanthemum, dried lotus, dried honeysuckle, dried mint, dried rose, etc.

[0055] Exemplarily, the sheet-like edible additive includes VC effervescent tablets.

[0056] In other embodiments, the additive 22 may also be other gifts or printed products, or lottery tickets, similar to scratch cards, or blind box toys, to increase the pleasure attribute of the beverage.

[0057] like Figure 3 Zhihe Figure 5As shown, the cover body 21 includes a top plate portion 211, a frame portion 212 and a receiving portion 213. It can be understood that the cover body 21 is an integrally formed structure, that is, the top plate portion 211, the frame portion 212 and the receiving portion 213 are various parts of the cover body 21. In this way, the structure of the cover body 21 is simpler, and the process of forming the cover body 21 is simpler, which is conducive to reducing the process cost.

[0058] The top plate portion 211 includes a top surface 2111 and a bottom surface 2112 disposed opposite to each other. The frame portion 212 is fixed to the bottom surface 2112 of the top plate portion 211, and the frame portion 212 and the top plate portion 211 enclose a first space 214. The first space 214 is used to install the bottle body 10 (see Figure 2 ) of the bottle mouth 11 (please refer to Figure 2 ), that is, the frame portion 212 and the top plate portion 211 can seal the bottle mouth 11 of the bottle body 10.

[0059] In one embodiment, the inner side surface of the frame portion 212 is provided with an internal thread 201, and the internal thread 201 of the frame portion 212 can be connected to the bottle body 10 (see Figure 2 ) external thread 111 (see Figure 2 ) threaded connection. In this way, the connection between the bottle cap 20 and the bottle body 10 is more firm and stable.

[0060] like Figure 3 Zhihe Figure 5 As shown, the receiving portion 213 is fixed to the bottom surface 2112 of the top plate portion 211. In a possible implementation manner, the receiving portion 213 is connected to the middle portion of the top plate portion 211.

[0061] In addition, at least a portion of the accommodating portion 213 is located in the first space 214. The accommodating portion 213 encloses a second space 215. The top plate portion 211 is provided with a through hole 216, which passes through from the top surface 2111 of the top plate portion 211 to the bottom surface 2112 of the top plate portion 211. The through hole 216 is connected to the second space 215;

[0062] In addition, the easy-tear film 23 is fixed to the top surface 2111 of the top plate portion 211 . The easy-tear film 23 seals the through hole 216 and the second space 215 .

[0063] Figure 6 yes Figure 4 The bottle cap 20 shown is a partial structural schematic diagram of an embodiment.

[0064] See also Figure 6 , and combined with Figures 3 to 5 As shown, the additive 22 is located in the second space 215. It is understandable that, since the tear film 23 seals the through hole 216 and the second space 215, when the additive 22 is located in the second space 215, the additive 22 is not easily affected by moisture and deteriorated.

[0065] In one embodiment, the bottle cap 20 also includes a capsule (not shown). The additive 22 is arranged in the capsule. It is understandable that, compared with the solution of directly placing the additive 22 in the second space 215, by arranging the additive 22 in the capsule, on the one hand, the additive 22 is relatively clean and simple and not easily contaminated, and on the other hand, the additive 22 will not be scattered or remain in the second space 215 to avoid scattering. It is understandable that the capsule can be made of animal and plant pectin, which is a natural ingredient and is easily soluble in water. In this way, when the user needs to drink liquid, after opening the easy-tear film 23, the capsule is directly placed in the liquid. After the capsule is dissolved, the additive 22 can be dissolved in the liquid.

[0066] like Figures 1 to 6 As shown, when the user needs to drink, the bottle cap 20 of the drinking bottle 100 can be removed from the bottle body 10 first. Then the easy-tear film 23 can be torn off from the cover 21. Finally, the additive 22 in the second space 215 is poured into the liquid in the bottle body 10, and it can be drunk after being fully stirred. Of course, the easy-tear film 23 can also be torn off first, and then the bottle cap 20 can be removed from the bottle body 10. The specific operation can be based on the user's habits. This application is not limited

[0067] For example, when the additive 22 is dried chrysanthemum, dried lotus, dried honeysuckle, dried mint or dried rose, etc., after the dried chrysanthemum, dried lotus, dried honeysuckle, dried mint or dried rose is poured into the liquid in the bottle 10, it can be directly consumed after a short wait. Of course, it can also be heated and brewed before drinking.

[0068] Compared with beverages on the market, many beverages are already mixed with additives, such as chrysanthemum tea. For these beverages, in order to ensure that they do not deteriorate, a large amount of additives such as preservatives are added to the beverages. When users need to drink, it will have an adverse effect on their health. Another example is medicated beverages. For these beverages, since medicated solid plants are directly added to water and are prone to deterioration, a large amount of additives must be added to the beverages. In this way, after a long period of light exposure, many medicinal ingredients will be decomposed, destroyed, and even produce toxic substances. When users need to drink, it will have a certain impact on their health. In this embodiment, by additionally arranging a second space 215 and an easy-to-tear film 23 on the cover body 21, and arranging the additive 22 in the second space 215, the liquid and the additive 22 of the drinking bottle 100 can be arranged separately. In this way, when the user needs to drink, the additive 22 is taken out and poured into the liquid of the bottle body 10, and it can be drunk after being fully stirred. At this time, the liquid in the bottle body 10 does not need to be added with a large amount of preservatives or other additives, ensuring that the liquid will not have an adverse effect on health.

[0069] It can be understood that, compared with the solution of setting the easy-tear film 23 inside the bottle body 10, the present embodiment sets the easy-tear film 23 outside the bottle body 10. At this time, on the one hand, the easy-tear film 23 is not easy to contaminate the liquid due to the liquid soaked in the bottle body 10, and on the other hand, the easy-tear film 23 is not easy to tear off due to soaking in the liquid.

[0070] It is understandable that when the bottle cap 20 is installed in the bottle body 10, the receiving portion 213 can be located inside the bottle body 10. At this time, the shape of the receiving portion 213 will not affect the appearance of the drinking bottle 100. In this way, the appearance of the drinking bottle 100 is better. In addition, since the receiving portion 213 can be located inside the bottle body 10, the receiving portion 213 can be free from impact by external objects. In this way, the wall thickness of the receiving portion 213 can be reduced to a large extent. At this time, the bottle cap 20 can reduce the material cost of production to a large extent. In addition, the bottle cap 20 can also be easier to produce and process.

[0071] like Figure 5 and Figure 6 As shown, in one embodiment, the top plate portion 211 is provided with a receiving groove 217 , the receiving groove 217 forms an opening on the top surface 2111 of the top plate portion 211 , and the receiving groove 217 is connected to the through hole 216 .

[0072] See also Figure 4 , and combined with Figure 5 and Figure 6 As shown, the tear film 23 is fixed in the receiving groove 217. In this way, on the one hand, the tear film 23 does not occupy a large space in the thickness direction of the bottle cap 20. On the other hand, the top plate 211 can protect the tear film 23 and prevent the tear film 23 from falling off due to scratching.

[0073] In a possible embodiment, the top surface 231 of the easy-tear film 23 is flush with the top surface 2111 of the top plate portion 211, or the top surface 231 of the easy-tear film 23 is located in the receiving groove 217. In this case, the easy-tear film 23 can be completely located in the receiving groove 217. On the one hand, the easy-tear film 23 does not occupy a large space in the thickness direction of the bottle cap 20. On the other hand, the top plate portion 211 can protect the easy-tear film 23 and prevent the easy-tear film 23 from falling off due to scratching.

[0074] like Figures 3 to 5 As shown, in a possible implementation manner, the distance between the bottom surface 2131 of the accommodating portion 213 and the top surface 2111 of the top plate portion 211 is the first height. The bottom surface 2131 of the accommodating portion 213 is the surface of the accommodating portion 213 away from the top plate portion 211.

[0075] In addition, the distance between the bottom surface 2121 of the frame portion 212 and the top surface 2111 of the top plate portion 211 is a second height, which is less than or equal to the first height. The bottom surface 2121 of the frame portion 212 is a surface of the frame portion 212 away from the top plate portion 211.

[0076] It is understandable that by setting the second height to be less than or equal to the first height, the volume of the receiving portion 213 can be greatly increased, that is, the volume of the second space 215 can be greatly increased. In this way, the second space 215 can accommodate more additives 22.

[0077] In a possible implementation, the first height is in the range of 13 mm to 50 mm. Exemplarily, the first height can be 13 mm, 20 mm, 25 mm, 30 mm, 36 mm, 40 mm, 45 mm or 50 mm.

[0078] In a possible implementation, the second height is in the range of 10 mm to 15 mm. For example, the second height may be 10 mm, 12 mm, 13 mm or 15 mm.

[0079] like Figures 3 to 5 As shown, in one embodiment, the outer side surface 2123 of the frame portion 212 is roughened. In this way, when the user removes the bottle cap 20 from the bottle body 10, it is not easy to slip off, thereby making it more convenient for the user to remove the bottle cap 20 from the bottle body 10.

[0080] In one embodiment, the outer side surface 2123 of the frame portion 212 is provided with a plurality of grooves, and / or the outer side surface 2123 of the frame portion 212 is provided with a plurality of protrusions. In this way, the roughness of the outer side surface 2123 of the frame portion 212 can be greatly improved.

[0081] like Figures 3 to 5 As shown, in one embodiment, the outer side surface 2113 of the top plate portion 211 may also be roughened. The roughening of the top plate portion 211 may refer to the roughening of the outer side surface 2123 of the frame portion 212. The details are not repeated here.

[0082] In a possible implementation manner, the cross-sectional shape of the outer side surface 2133 of the accommodating portion 213 is circular, elliptical, triangular, trapezoidal, or polygonal.

[0083] Figure 7 yes Figure 2 The bottle cap 20 is shown in an exploded schematic diagram in another embodiment.

[0084] like Figure 7As shown, in one embodiment, the cover 21 further includes a partition 218, the partition 218 is located in the second space 215, the partition 218 is connected to the receiving portion 213, and the partition 218 divides the second space 215 into a plurality of subspaces 2151. It can be understood that Figure 7 It is schematically shown that the partition 218 divides the second space 215 into two subspaces 2151. In other embodiments, the partition 218 can also divide the second space 215 into three subspaces 2151, four subspaces 2151, or more subspaces 2151.

[0085] Exemplarily, the additive 22 includes a plurality of seed additives 221 , and the plurality of seed additives 221 are disposed in a one-to-one correspondence in the plurality of subspaces 2151 .

[0086] It is understandable that by dividing the second space 215 into a plurality of sub-spaces 2151, the plurality of sub-spaces 2151 are utilized to accommodate different sub-additives 221. In this way, the cover 21 can hold more types of additives 22, and the user has more choices, which is conducive to improving the user experience.

[0087] It should be noted that all the above drawings are illustrative illustrations of the present application and do not represent the actual size of the product. Moreover, the size ratio relationship between the components in the drawings is not intended to limit the actual product of the present application.

[0088] The above description is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.

[0089] In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application, that is, the multiple embodiments described above can also be combined arbitrarily according to actual needs. Therefore, the protection scope of this application shall be based on the protection scope of the claims.
