Description

Technical Field

[0001] The utility model relates to the field of packaging bottles, in particular to an anti-falling material releaser, a bottle cap assembly and a packaging bottle. Background Art

[0002] In the past, ready-mixed beverages on the market were welcomed by many consumers due to their novel drinking methods. The packaging bottle of ready-mixed beverages usually consists of a bottle cap, a material releaser assembled in the bottle cap, and a bottle body. The bottle cap includes a material bin, which contains solid powder and is sealed by a material seal. When the bottle cap is twisted open, the material seal is cut open by the material releaser, so that the solid powder falls into the liquid in the bottle body.

[0003] The user usually uses it by opening the bottle cap to allow the powder stored in the silo to enter the bottle body, then closing the bottle cap assembly and shaking the bottle to fully mix the powder and liquid. In the current bottle cap assembly structure, after opening and then closing, the material releaser returns to the original position, which may cause the cut material seal to fall off and enter the bottle body, or even the material releaser to fall off and enter the bottle body.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0070] First embodiment

[0071] The embodiment of the utility model provides an anti-falling material releaser 200, a bottle cap assembly and a packaging bottle 10.

[0072] like Figure 7 As shown, the bottle cap assembly provided in this embodiment includes an upper cover body 100, a lower ring body 300 and a material releaser 200 provided in this embodiment.

[0073] like Figure 7 and Figure 8 As shown, the upper cover body 100 includes a cover body 110 and a cylindrical silo 120 for storing powder, and the silo 120 includes a silo wall 121 and a material seal 122; one end of the silo wall 121 is connected to the inner top wall of the cover body 110, and the silo wall 121 forms a material cavity for storing materials, and the material seal 122 is made of a film material, and the material seal 122 is used to seal the material in the material cavity; the end of the other end of the silo wall 121 is the driving part 101, and the outer wall of the driving part 101 is provided with a first external drive component 130.

[0074] like Figures 1 to 3 As shown, the material releaser 200 includes a cylindrical body 210 and a material release member 220 disposed in the cylindrical body 210; one end of the cylindrical body 210 has a first opening 211 for the silo 120 to enter, and the opposite end has a second opening 212 for the powder in the silo 120 to pass through after being released.

[0075] In order to more clearly describe the structural relationship between the first inner drive member 213 of the material releaser 200 and the first outer drive member 130 of the cylindrical body 210, a simplified structural diagram is provided: Figures 4 to 6 .like Figures 4 to 6As shown, the cylindrical body 210 has a driving function part 215 and a recessed part 216, and the inner wall of the driving function part 215 is provided with a first inner driving part 213 that cooperates with the first outer driving part 130 of the outer wall of the silo 120. The end of the silo 120 provided with the first outer driving part 130 is the driving part 101, and the length of the driving part 101 in the axial direction of the silo 120 is a, and the length of the recessed part 216 in the axial direction of the cylindrical body 210 is b, b ≥ a, and the recessed part 216 is used to accommodate the first outer driving part 130 that loses the cooperation with the first inner driving part 213.

[0076] like Figure 7 and Figure 8 As shown, the inner wall of the cover body 110 is provided with a second inner drive member 111, and the outer wall of the lower ring body 300 is provided with a second outer drive member 301 matching the second inner drive member 111;

[0077] Initially, the upper cover body 100 is covered on the lower ring body 300, the material releaser 200 is located in the lower ring body 300, the first inner drive member 213 and the first outer drive member 130 are arranged in cooperation with each other, the end of the silo 120 away from the cover body 110 extends into the cylindrical body 210, and there is a gap between the material seal 122 and the material release member 220;

[0078] Open the bottle cap assembly, screw the upper cover body 100, and under the cooperation of the second inner drive member 111 and the second outer drive member 301, the upper cover body 100 moves upward relative to the lower ring body 300; and under the cooperation of the first outer drive member 130 and the first inner drive member 213, the material releaser 200 moves upward relative to the silo 120. During the upward movement of the material releaser 200, the cylindrical body 210 is gradually sleeved on the outer wall of the silo 120 through the first opening 211, and the material release member 220 cuts the material seal 122 and gradually enters into the silo 120. The silo 120 is opened, and the powder stored in the silo 120 is released through the second opening 212.

[0079] The cover body 100 is screwed on continuously, and the first external drive component 130 loses its cooperation with the first internal drive component 213 , and the first external drive component 130 enters into the empty portion 216 .

[0080] After the bottle cap assembly provided in this embodiment is assembled into a drink, the user usually uses it in the following ways: open the bottle cap assembly to allow the material stored in the silo 120 to enter the liquid in the packaging bottle 10, and then close the bottle cap assembly and shake the packaging bottle 10 to fully mix the powder and the liquid. When the bottle cap assembly is opened, the material seal 122 is usually clamped between the inner wall of the silo 120 and the outer wall of the material release 220 after being cut. When the bottle cap assembly is closed again, the material releaser 200 returns to the initial position so that the silo 120 and the material release 220 no longer clamp the material seal 122, which may cause the material seal 122 to fall into the lower bottle body, affecting the drinking experience, or even being swallowed by mistake and causing a safety accident. In addition, when the lower ring body 300 does not have a limiting function for the material releaser 200 in the height direction, the material releaser 200 may fall into the lower bottle body when it returns to the lower ring body 300, which also poses a safety problem of being swallowed by the drinker by mistake.

[0081] The material releaser 200 and bottle cap assembly provided in the present embodiment have a hollow portion 216 of suitable length without the first inner drive member 213 on the inner wall of the cylindrical main body 210. In this way, when the upper cover body 100 is screwed to the bottom, the first outer drive member 130 loses the cooperation with the first inner drive member 213 and enters the hollow portion 216. When the upper cover body 100 is screwed in the opposite direction to close the bottle cap assembly again, the first inner drive member 213 and the first outer drive member 130 lose their cooperation. At this time, the material releaser 200 will no longer be driven to move downward relative to the material bin 120 as the material bin 120 rotates. Therefore, even if the upper cover body 100 is re-covered on the lower ring body 300, the material releaser 200 is still sleeved on the outer wall of the material bin 120, and the material releaser 200 will not fall off from the outer wall of the material bin 120, which can effectively avoid the inconvenience or safety problems caused by the material releaser 200 falling off.

[0082] Optionally, the structure of the recessed portion 216 may be a smooth structure without the first inner drive part 213 on the side wall, or may be a structure with other structures on the side wall, but these structures do not form a matching relationship with the first outer drive part 130, and do not affect the structure of the silo 120 rotating relative to the cylindrical body 210. In short, the purpose of setting the recessed portion 216 is to accommodate the first inner drive part 213 that loses its matching effect with the first outer drive part 130, and to prevent the upper cover body 100 from screwing back and causing the material releaser 200 to move downward relative to the silo 120 due to the re-matching of the first inner drive part 213 and the first outer drive part 130. Therefore, as long as the structure of the recessed portion 216 can accommodate the first inner drive part 213 that loses its matching effect with the first outer drive part 130 and does not affect the rotation of the silo 120 relative to the cylindrical body 210, it should be within the protection scope of the present invention.

[0083] Optionally, the first inner drive component 213 is a first inner thread 213, and the first outer drive component 130 is a first outer thread 130; the second inner drive component 111 is a second inner thread 111, and the second outer drive component 301 is a second outer thread 301; the spiral directions of the second inner drive component 111 and the first outer drive component 130 are opposite.

[0084] When the upper cover body 100 is screwed, the upper cover body 100 moves up relative to the lower ring body 300 under the cooperation of the second internal thread 111 and the second external thread 301. At the same time, under the cooperation of the first internal thread 213 and the first external thread 130, the material releaser 200 moves up relative to the silo 120.

[0085] Due to the setting of the recessed portion 216, when the upper cover body 100 is screwed to the bottom, the first external thread 130 slides off the first internal thread 213 and enters the recessed portion 216. When the upper cover body 100 is screwed back again to close the bottle cap assembly, the first internal thread 213 and the first external thread 130 no longer cooperate with each other. At this time, the silo 120 rotates in the cylindrical body 210, and the material releaser 200 will no longer move downward relative to the silo 120 as the silo 120 rotates. Even if the upper cover body 100 is screwed back onto the lower ring body 300, the material releaser 200 is still sleeved on the outer wall of the silo 120. Since the first internal thread 213 is located above the first external thread 130, it is equivalent to the material releaser 200 being hung outside the silo 120 by the first external thread 130. The material releaser 200 will not fall off the outer wall of the silo 120, and the inconvenience or safety problems caused by the falling off of the material releaser 200 can be effectively avoided.

[0086] It should be noted that the screw drive is only a preferred embodiment of the present invention. In other embodiments of the present invention, any other driving method that can realize the upward movement of the material releaser 200 by screwing the upper cover 100 can be used. In the present application, as long as the first external drive component 130 enters the empty portion 216, the cooperation between the first external drive component 213 and the first internal drive component 213 disappears, and the material releaser 200 can be effectively prevented from being separated. Other driving methods can be, for example: one of the first internal drive component 213 and the first external drive component 130 is a component with a spiral arc edge, and the other is a component that can abut against the spiral arc edge, and as the upper cover body is screwed, the first internal drive component 213 and the first external drive component 130 move relatively along the trajectory of the spiral arc edge.

[0087] The specific structure of the driving unit 101 can be of the following two types:

[0088] The first type: Figure 4 and Figure 5As shown, one end of the first external thread 130 extends to the edge of the end of the bin wall 121 away from the cover body 110, and in the axial direction, the length of the driving portion 101 is equal to the length of the first external thread 130;

[0089] The second type: Figure 6 As shown, there is a blank area 160 with a length of c between the first external thread 130 and the edge of the end of the warehouse wall 121 away from the cover body 110. In the axial direction, the length of the first external thread 130 is d, and the driving part 101 is composed of the part corresponding to the blank area 160 and the part corresponding to the first external thread 130, that is, a=c+d.

[0090] Alternatively, if Figure 7 and Figure 8 As shown, the cover body 110 has a cover opening 110 a , and the cover body 110 is covered on the lower ring body 300 through the cover opening 110 a , and the material bin 120 is located in the cover body 110 and does not extend out of the cover opening 110 a .

[0091] Taking the packaging bottle 10 as a beverage packaging bottle 10, the material bin 120 does not extend out of the cover opening 110a, that is, the bottom of the material bin 120 is not lower than the bottom edge of the cover body 110. Since some drinkers have the habit of opening the upper cover body 100 and placing the upper cover body 100 on the desktop at will, if the material bin 120 extends out of the cover opening 110a, the material bin 120 is easily contaminated by contact with the desktop. Generally speaking, the beverage in the bottle body will not be drunk all at once after the upper cover body 100 is opened. When the upper cover body 100 is covered on the lower ring body 300 again, the material bin 120 will bring pollutants into the bottle body, which is not good for human health when drinking again. Therefore, making the material bin 120 not extend out of the cover opening 110a can well avoid the above problems.

[0092] Optionally, in order to increase the friction between the hand and the upper cover body 100 when twisting, the outer wall of the cover body 110 can be provided with an uneven structure. Preferably, in order to meet market demand, these uneven structures can be patterns.

[0093] Alternatively, if Figure 7 As shown, the lower ring body accommodating chamber 150 is formed between the chamber wall 121 and the inner wall of the cover body 110. The lower ring body accommodating chamber 150 is provided with a circle of first convex rings 141 and a circle of second convex rings 142 on the top wall of the cover body 110 corresponding to the cover body 110. The second convex ring 142 is located inside the ring of the first convex ring 141. When the upper cover body 100 is covered on the lower ring body 300, the end of the lower ring body 300 is sandwiched between the first convex ring 141 and the second convex ring 142.

[0094] The provision of the first convex ring 141 and the second convex ring 142 can increase the sealing performance between the upper cover body 100 and the lower ring body 300 .

[0095] Furthermore, the outer side of the second convex ring 142 bulges outward, so that the outer side of the second convex ring 142 abuts against the inner wall of the lower ring body 300, thereby further improving the sealing effect.

[0096] Optionally, a third protruding ring 143 is further provided on the top wall of the cover body 110 corresponding to the lower ring body accommodating cavity 150, and the third protruding ring 143 is located between the first protruding ring 141 and the second protruding ring 142. When the upper cover body 100 is covered on the lower ring body 300, the end of the lower ring body 300 abuts against the end of the third protruding ring 143.

[0097] The provision of the third protruding ring 143 can further improve the sealing performance between the upper cover body 100 and the lower ring body 300 .

[0098] Optionally, taking the illustrated structure of this embodiment as an example, the material seal 122 is a diaphragm, the material is disposed in the material cavity, and the diaphragm is disposed at one end of the bin wall 121 away from the top wall of the upper cover body 100 to seal the material cavity.

[0099] It should be noted that, in other embodiments of the utility model, the material sealing member 122 may also be a capsule, in which the material is sealed, and the capsule is disposed in the material cavity.

[0100] Alternatively, if Figures 1 to 3 As shown, the material release member 220 includes a stopper 240 and a material release structure 221 . The material release structure 221 is disposed at one end of the stopper 240 , and the other end of the stopper 240 is connected to the cylindrical body 210 via a connector 230 .

[0101] Optionally, the material releasing structure 221 is a cutting structure and / or a puncturing structure.

[0102] Preferably, the stopper 240 is a stopper ring 240, the connecting member 230 is a connecting ring 230, the inner side of the connecting ring 230 is connected to the stopper ring 240, and the outer side of the connecting ring 230 is connected to the cylindrical body 210. The opening formed in a circle on the inner side of the connecting ring 230 is the second opening 212.

[0103] During the upward movement of the material releaser 200 , the material release structure 221 punctures the material seal 122 . As the material releaser 200 moves upward, the material seal 122 is opened, and the opened material seal 122 is clamped between the retaining ring 240 and the inner wall of the silo 120 .

[0104] Alternatively, if Figure 7 As shown, the inner diameter of the silo 120 is 0.3-1.0 mm larger than the outer diameter of the retaining ring 240 .

[0105] When the bottle cap assembly is opened, the material release member 220 cuts the broken material seal 122 and gradually enters into the silo 120 . The cut broken material seal 122 is gradually sandwiched between the inner wall of the silo 120 and the outer wall of the retaining ring 240 , and the powder stored in the silo 120 is released through the second opening 212 .

[0106] When the bottle cap assembly is opened, the material releaser 200 moves upward from the lower ring body 300 to cut the material seal 122, and the silo 120 opens to allow the powder to fall below and mix with the liquid. Since the inner diameter of the silo 120 is 0.3 to 1.0 mm larger than the outer diameter of the retaining ring 240, the spacing between the silo 120 and the retaining ring 240 is 0.3 to 1.0 mm after the material releaser 200 moves upward. For the types and thicknesses of common membrane materials on the market, this size of gap can ensure that the cut material seal 122 is clamped into the gap, avoiding the problem that the material seal 122 is difficult to enter the gap, thereby effectively avoiding the material seal 122 from being stuck in the material releaser 200 after being cut, and the material seal 122 blocking the powder from falling.

[0107] Optionally, the material of the material seal 122 may be, for example, polyethylene (PE), polyvinyl alcohol (PVOH), polypropylene (PP), polyvinyl acetate (EVA), polyester (PET), aluminum foil, etc.

[0108] Optionally, the material seal 122 has a thickness of 50 μm to 100 μm, for example, 50 μm, 55 μm, 60 μm, 70 μm, 75 μm, 80 μm, 90 μm or 100 μm.

[0109] Alternatively, if Figure 7 and Figure 8 As shown, the first external thread 130 is composed of at least one first spiral ridge 131; the first internal thread 213 is composed of at least one second spiral ridge 213a, all the second spiral ridges 213a surround at least one spiral groove 213b, the number of spiral grooves 213b is greater than or equal to the number of first spiral ridges 131, and each spiral ridge has at least one spiral groove 213b matching it. When the upper cover body 100 and the material releaser 200 are assembled, each first spiral ridge 131 is inserted into the corresponding spiral groove 213b.

[0110] Preferably, the number of the first spiral ridges 131 is the same as the number of the spiral grooves 213 b , and when the upper cover 100 and the material releaser 200 are assembled, the first spiral ridges 131 are inserted into the corresponding spiral grooves 213 b one by one.

[0111] Furthermore, one end of each first spiral convex strip 131 away from the cover body 110 is a starting end 131 a . Initially, the starting end 131 a of each first spiral convex strip 131 is located in the corresponding spiral groove 213 b .

[0112] Initially, the starting end 131a of each first spiral ridge 131 is located in the corresponding spiral groove 213b, so that when the cover body 100 is screwed on, the bin wall 121 can hook up the material releaser 200, so that the material releaser 200 moves upward together.

[0113] by Figure 8 Taking the structure shown as an example, the number of the second spiral ridges 213a is 3, and the number of the corresponding spiral grooves 213b is 3. Correspondingly, the number of the first spiral ridges 131 is also 3.

[0114] Alternatively, if Figures 1 to 3 As shown, the material release structure 221 is a cutting structure, which includes at least one pointed cone-shaped cutting knife 221 ; one end of the retaining ring 240 is connected to the cylindrical body 210 through the connecting ring 230 , and the other end of the retaining ring 240 is connected to each cutting knife 221 .

[0115] The pointed cone-shaped cutting knife 221 can more easily pierce the material seal 122 , and the specific configuration of the cutting knife 221 blade enables it to easily cut even the material seal 122 with high strength and toughness, without creating obvious resistance to the twisting of the upper cover body 100 .

[0116] Alternatively, if Figures 1 to 3 as well as Figure 7 As shown, there are multiple cutting knives 221, and the multiple cutting knives 221 pierce the material seal 122 from multiple positions, so that the material seal 122 can be cut more quickly when the cover 100 is screwed on. Taking the structure shown in the figure of this application as an example, the number of the cutting knives 221 is 2.

[0117] Optionally, a plurality of powder leakage holes 231 are evenly formed on the connection ring 230 , and a connection block 232 is formed between two adjacent powder leakage holes 231 .

[0118] The connecting ring 230 is used to connect the cylindrical body 210 and the material release member 220. A plurality of powder leakage holes 231 are arranged on the connecting ring 230 so that the powder falling into the gap between the connecting ring 230 and the bin wall 121 after cutting can fall out. On the other hand, it can also reduce the manufacturing materials of the material releaser 200 and save manufacturing costs.

[0119] Optionally, in order to ensure the stability of the connection between the material release member 220 and the cylindrical body 210, the number of the powder leakage holes 231 is 2 to 4. Taking the structure shown in the figure as an example, the number of the powder leakage holes 231 is 3.

[0120] Optionally, a circle of limiting ring 260 is provided on the outer wall of one end of the material releaser 200 corresponding to the first opening 211, and the inner wall of the lower part of the lower ring body 300 protrudes inward to form an annular boss, and the inner diameter of the annular boss is smaller than the outer diameter of the limiting ring 260. Initially, the limiting ring 260 is hung on the annular boss.

[0121] The arrangement of the limiting ring 260 and the limiting boss 312 can prevent the material releaser 200 from sliding downward from the lower ring body 300 into the bottle body during assembly.

[0122] like Figure 1 and Fig. 9 As shown, optionally, the outer wall of the material releaser 200 is provided with a plurality of limiting ridges 270 parallel to its axial direction, and the inner wall of the lower ring body 300 is provided with a plurality of limiting grooves 311 parallel to its axial direction, the number of the plurality of limiting grooves 311 is an integer multiple of the number of the limiting ridges 270, the distribution positions of the plurality of limiting grooves 311 match the distribution positions of the plurality of limiting ridges 270, and each limiting ridge 270 can be inserted into any limiting groove 311; initially, the plurality of limiting ridges 270 are inserted into the corresponding limiting grooves 311.

[0123] The arrangement of the limiting convex strip 270 and the limiting groove 311 can ensure that when the upper cover body 100 is screwed, the material releaser 200 will not be driven to rotate, thereby achieving the material releaser 200 to rotate and move upward relative to the silo 120 .

[0124] Optionally, the number of the limiting ridges 270 is 4 to 7, and the number of the limiting grooves 311 is 2 to 4 times the number of the limiting ridges 270. Taking the structure shown in the figure as an example, the number of the limiting ridges 270 is 6, and the number of the limiting grooves 311 is 18.

[0125] Generally speaking, the more limiting ridges 270 and limiting grooves 311 are set, the easier it is for the material releaser 200 to be inserted into the corresponding limiting groove 311 from a suitable angle. However, taking into account the simplification of the structure and the reduction of manufacturing costs, the above-mentioned number of settings is selected to take into account the convenience of installation of the material releaser 200 and save manufacturing costs.

[0126] like Figure 7 As shown, this embodiment further provides a packaging bottle 10, which includes a bottle body 510 and a bottle cap assembly provided in this embodiment; in the packaging bottle 10 provided in this embodiment, the lower ring body 300 serves as a bottle mouth 520 and is integrally formed with the bottle body 510 to form a bottle body.

[0127] Second embodiment

[0128] This embodiment provides a bottle cap assembly and a packaging bottle 10, which are similar to the first embodiment, and reference is made to the first embodiment for matters not mentioned.

[0129] Fig.10 As shown, the bottle cap assembly provided in this embodiment further includes a bottle mouth connecting ring 400, which is connected to the lower ring body 300 and formed integrally. The bottle cap assembly is covered on the bottle mouth 520 of the bottle body through the bottle mouth connecting ring 400. Fig.11 As shown, the material bin 120 of the upper cover body 100 of the bottle cap assembly provided in this embodiment is different from that in the first embodiment, and it extends out of the cover opening 110a.

[0130] like Fig.10 As shown, the packaging bottle 10 provided in this embodiment includes a bottle body and a bottle cap assembly provided in this embodiment, and the bottle mouth 520 of the bottle body is threadedly connected to the bottle mouth connecting ring 400, that is, the inner wall of the bottle mouth connecting ring 400 is provided with an internal thread, and the outer wall of the bottle mouth 520 is provided with an external thread, and the connection is achieved by the cooperation of the internal thread and the external thread.

[0131] In summary, the material releaser and bottle cap assembly provided by the embodiment of the utility model, since the inner wall of the cylindrical main body has a hollow portion of suitable length, it can be achieved that when the upper cover body is screwed to the bottom, the first outer drive component loses the cooperation with the first inner drive component and enters the hollow portion. When the upper cover body is screwed in the opposite direction again to close the bottle cap assembly again, the first inner drive component and the first outer drive component lose their cooperation. At this time, the material releaser will no longer be driven to move downward relative to the material bin as the material bin rotates. Therefore, even if the upper cover body is re-covered on the lower ring body, the material releaser is still sleeved on the outer wall of the material bin, and the material releaser will not fall off from the outer wall of the material bin, which can effectively avoid the inconvenience or safety problems caused by the falling off of the material releaser.

[0132] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
