First embodiment

Embodiments of the present utility model provide an anti-drop material release 200, a bottle cap assembly and a packaging bottle 10.

As shown in fig. 7, the bottle cap assembly provided in this embodiment includes an upper cap body 100, a lower ring body 300, and a material releaser 200 provided in this embodiment.

As shown in fig. 7 and 8, the upper cover 100 comprises a cover main body 110 and a cylindrical bin 120 for storing powder, the bin 120 comprises a bin wall 121 and a material sealing member 122, one end of the bin wall 121 is connected with the inner top wall of the cover main body 110, the bin wall 121 encloses a material cavity for storing the material, the material sealing member 122 is made of a film material, the material sealing member 122 is used for sealing the material in the material cavity, the end of the other end of the bin wall 121 is provided with a driving part 101, and the outer wall of the driving part 101 is provided with a first outer driving member 130.

As shown in fig. 1 to 3, the material releaser 200 includes a cylindrical body 210 and a material releaser 220 provided in the cylindrical body 210, one end of the cylindrical body 210 having a first opening 211 into which the bin 120 is introduced, and the opposite end having a second opening 212 through which the powder in the bin 120 is released.

To more clearly describe the structural relationship of the first inner drive member 213 of the material dispenser 200 and the first outer drive member 130 of the cylindrical body 210, a simplified construction is provided, FIGS. 4-6. As shown in fig. 4 to 6, the cylindrical body 210 has a driving function portion 215 and a hollow portion 216, and the inner wall of the driving function portion 215 is provided with a first inner driver 213 that is engaged with the first outer driver 130 of the outer wall of the magazine 120. The end of the bin 120 provided with the first external driving member 130 is a driving portion 101, the length of the driving portion 101 is a in the axial direction of the bin 120, the length of the clearance portion 216 is b, b is greater than or equal to a in the axial direction of the cylindrical main body 210, and the clearance portion 216 is used for accommodating the first external driving member 130 which is out of cooperation with the first internal driving member 213.

As shown in fig. 7 and 8, the inner sidewall of the cover main body 110 is provided with a second inner driving piece 111, and the outer sidewall of the lower ring body 300 is provided with a second outer driving piece 301 matched with the second inner driving piece 111;

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 driving member 213 and the first outer driving member 130 are mutually matched, one end of the storage bin 120, which is far away from the cover main body 110, extends into the cylindrical main body 210, and a gap is formed between the material sealing member 122 and the material releasing member 220;

The bottle cap assembly is opened, the upper cover body 100 is screwed, the upper cover body 100 moves upwards relative to the lower ring body 300 under the cooperation of the second inner driving piece 111 and the second outer driving piece 301, the material releaser 200 moves upwards relative to the storage bin 120 under the cooperation of the first outer driving piece 130 and the first inner driving piece 213, the cylindrical main body 210 is gradually sleeved on the outer wall of the storage bin 120 through the first opening 211 in the process of moving the material releaser 200 upwards, the material releaser 220 cuts the material sealing piece 122 and gradually enters the storage bin 120, the storage bin 120 is opened, and powder stored in the storage bin 120 is released through the second opening 212;

continuing to screw the upper cover 100, the first outer driving member 130 loses the cooperation with the first inner driving member 213, and the first outer driving member 130 enters the hollow portion 216.

After the bottle cap assembly is assembled into a beverage, the bottle cap assembly is generally used by a user in such a way that the material stored in the bin 120 is introduced into the liquid in the packaging bottle 10, and then the bottle cap assembly is closed, and the packaging bottle 10 is shaken to mix the powder and the liquid sufficiently. Since the material sealing member 122 is usually clamped between the inner wall of the bin 120 and the outer wall of the material releasing member 220 after being cut when the bottle cap assembly is opened, when the bottle cap assembly is closed again, the material releaser 200 returns to the initial position so that the bin 120 and the material releasing member 220 do not clamp the material sealing member 122 any more, which may cause the material sealing member 122 to fall into the bottle below to affect the drinking experience, and even cause a safety accident due to mistaking. In addition, when the lower ring 300 does not have a limiting function on the material releaser 200 in the height direction, the material releaser 200 may fall into the lower bottle body after returning into the lower ring 300, which also has a safety problem of being swallowed by a drinker.

In the material releaser 200 and the bottle cap assembly provided in this embodiment, since the inner wall of the cylindrical main body 210 has a section of the hollow portion 216 with a suitable length, in which the first inner driving member 213 is not provided, so that when the upper cover body 100 is screwed to the bottom, the first outer driving member 130 loses the fit with the first inner driving member 213 and enters into the hollow portion 216, when the upper cover body 100 is screwed back again to close the bottle cap assembly, the material releaser 200 is not driven to move downwards relative to the bin 120 along with the rotation of the bin 120, and even if the upper cover body 100 is re-capped on the outer wall of the bin 120, the material releaser 200 is still sleeved on the outer wall of the bin 120, so that the problem that the material releaser 200 falls off from the outer wall of the bin 120 is avoided, and the inconvenience or the safety problem caused by the falling of the material releaser 200 can be effectively avoided.

Alternatively, the hollow portion 216 may be a smooth structure with a sidewall that is not provided with the first inner driving member 213, or may be a structure with a sidewall that is provided with other structures, but that does not form a mating relationship with the first outer driving member 130 and does not affect the rotation of the cartridge 120 relative to the cylindrical body 210. In summary, the purpose of the recess 216 is to accommodate the first inner drive member 213 that is out of engagement with the first outer drive member 130, and to prevent the upper cover 100 from being screwed back down, resulting in the material releaser 200 being moved down relative to the bin 120, due to the first inner drive member 213 and the first outer drive member 130 being in engagement again. It is within the scope of the present invention to provide a structure of the hollow 216 that is capable of receiving the first inner driving member 213 that is out of engagement with the first outer driving member 130 and does not interfere with the rotation of the cartridge 120 relative to the tubular body 210.

Optionally, the first inner driving member 213 is a first inner thread 213, the first outer driving member 130 is a first outer thread 130, the second inner driving member 111 is a second inner thread 111, the second outer driving member 301 is a second outer thread 301, and the spiral directions of the second inner driving member 111 and the first outer driving member 130 are opposite.

When the upper cap body 100 is screwed, the upper cap body 100 moves upward relative to the lower ring body 300 under the cooperation of the second internal thread 111 and the second external thread 301, and at the same time, the material releaser 200 moves upward relative to the bin 120 under the cooperation of the first internal thread 213 and the first external thread 130.

Due to the arrangement of the hollow part 216, when the upper cover body 100 is screwed to the bottom, the first external thread 130 slides away from the first internal thread 213 and enters the hollow part 216, when the upper cover body 100 is screwed back again to close the bottle cap assembly again, the first internal thread 213 and the first external thread 130 do not have a matching effect, at this time, the bin 120 rotates in the cylindrical main body 210, and the material releaser 200 cannot move downwards relative to the bin 120 along with the rotation of the bin 120, so that even if the upper cover body 100 is screwed back again to the lower ring body 300, the material releaser 200 is still sleeved on the outer wall of the bin 120, and the first internal thread 213 is positioned above the first external thread 130, which is equivalent to the fact that the material releaser 200 is hung outside the bin 120 by the first external thread 130, the problem that the material releaser 200 falls off from the outer wall of the bin 120 can not occur, and the inconvenience or the safety problem caused by the falling of the material releaser 200 can be effectively avoided.

It should be noted that, the screw driving is only a preferred embodiment of the present utility model, and in other embodiments of the present utility model, any other driving method capable of driving the material releaser 200 to move upwards by screwing the cover 100 may be used, and in the present utility model, as long as the first outer driving member 130 enters the hollow portion 216, the cooperation between the first outer driving member and the first inner driving member 213 disappears, so that the material releaser 200 can be effectively prevented from being separated. For example, the other driving method may be a method in which one of the first inner driver 213 and the first outer driver 130 is a member having a spiral arc edge, and the other is a member capable of abutting against the spiral arc edge, and the first inner driver 213 and the first outer driver 130 are relatively moved along a track of the spiral arc edge in accordance with the screwing of the upper cover.

The specific structure of the driving section 101 may be as follows:

First, as shown in fig. 4 and 5, one end of the first external screw thread 130 extends to an edge of one end of the bin wall 121 remote from the cap body 110, and the length of the driving part 101 in the axial direction is equal to the length of the first external screw thread 130;

Second, as shown in fig. 6, a blank region 160 having a length c is provided between the first male screw 130 and the edge of the end of the chamber wall 121 remote from the cap body 110, and the length d of the first male screw 130 in the axial direction is defined by a=c+d, which is a portion corresponding to the blank region 160 and a portion corresponding to the first male screw 130, of the driving unit 101.

Alternatively, as shown in fig. 7 and 8, the cover main body 110 has a cover opening 110a, the cover main body 110 is covered on the lower ring body 300 through the cover opening 110a, and the bin 120 is located in the cover main body 110 and does not protrude from the cover opening 110a.

Taking the packaging bottle 10 as the beverage packaging bottle 10 as an example, the bin 120 does not extend out of the cover opening 110a, i.e. the bottommost end of the bin 120 is not lower than the bottom edge of the cover main body 110, because the habit of some drinkers is to place the upper cover body 100 on the tabletop at will after opening the upper cover body 100, if the bin 120 extends out of the cover opening 110a, the bin 120 is easy to contact with the tabletop to pollute, generally, the beverage in the bottle body after opening the upper cover body 100 cannot be completely drunk once, and when the upper cover body 100 is covered on the lower ring 300 again, the bin 120 brings the pollutant into the bottle body, which is unfavorable for the health of human body when drinking again. Therefore, the bin 120 does not protrude from the cover opening 110a, so that the above problem can be well avoided.

Alternatively, in order to increase friction between the hand and the upper cover body 100 during screwing, the outer wall of the cover body 110 may be provided with rugged structures, which may be patterns, preferably, in order to meet market demands.

Alternatively, as shown in fig. 7, a lower ring body accommodating cavity 150 is defined between the bin wall 121 and the inner wall of the cover main body 110, a circle of first convex rings 141 and a circle of second convex rings 142 are arranged on the top wall of the lower ring body accommodating cavity 150 corresponding to the cover main body 110, and the second convex rings 142 are positioned in the rings of the first convex rings 141. When the upper cover body 100 is covered on the lower ring body 300, the end portion of the lower ring body 300 is sandwiched between the first convex ring 141 and the second convex ring 142.

The provision of the first and second collars 141 and 142 can increase sealability between the upper cover body 100 and the lower ring body 300.

Further, the outer side of the second convex ring 142 is protruded outwards, so that the outer side of the second convex ring 142 is abutted against the inner wall of the lower ring body 300, and the sealing performance is further improved.

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

The provision of the third raised ring 143 can further improve the sealability between the upper cover body 100 and the lower ring body 300.

Optionally, taking the illustrated structure of the embodiment as an example, the material sealing member 122 is a membrane, where the material is disposed in the material cavity, and the membrane is disposed at an end of the bin wall 121 away from the top wall of the upper cover 100, so as to seal the material cavity.

It should be noted that, in other embodiments of the present 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.

Alternatively, as shown in fig. 1 to 3, 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 through the connection member 230.

Optionally, the material release structure 221 is a cutting structure and/or a piercing structure.

Preferably, the stopper 240 is a stopper ring 240, the connection member 230 is a connection ring 230, the inside of the connection ring 230 is connected with the stopper ring 240, and the outside of the connection ring 230 is connected with the cylindrical body 210. The opening formed by the ring side of the connecting ring 230 is the second opening 212.

During the upward movement of the material dispenser 200, the material release structure 221 pierces the material seal 122, and as the material dispenser 200 moves upward, the material seal 122 is opened, and the opened material seal 122 is sandwiched between the retainer ring 240 and the inner wall of the bin 120.

Alternatively, as shown in FIG. 7, the inner diameter of the bin 120 is 0.3-1.0 mm larger than the outer diameter of the baffle ring 240.

When the cap assembly is opened, the material releaser 200 moves up from within the lower ring 300 to cut the material seal 122 open and the bin 120 opens to allow powder to fall below to mix with liquid. Because the internal diameter of the bin 120 is 0.3-1.0 mm larger than the external diameter of the baffle ring 240, the distance between the bin 120 and the baffle ring 240 after the material releaser 200 moves up is 0.3-1.0 mm, and the gap with the size can ensure that the cut material sealing piece 122 is clamped in the gap according to the types and thicknesses of common film materials in the market, so that the problem that the material sealing piece 122 is not easy to enter the gap is avoided, and the phenomenon that the material releaser 200 is blocked after the material sealing piece 122 is cut is effectively avoided, and the material sealing piece 122 blocks powder from falling is avoided.

Alternatively, as shown in fig. 1-3 and 7, the number of cutting blades 221 is multiple, and multiple cutting blades 221 pierce the material seal 122 from multiple locations, thereby enabling the material seal 122 to be cut open more quickly when the cap 100 is screwed on.
