First embodiment

Embodiments of the present utility model provide a cutter 200, a bottle cap assembly that is not prone to storing liquids, and a packaging bottle 10.

As shown in fig. 1 to 3, the bottle cap assembly provided in this embodiment includes an upper cap body 100, a lower ring body 300, and a cutter 200 provided in this embodiment.

As shown in fig. 1 and 2, the cutter 200 provided in this embodiment includes a cylindrical main body 210 and a cutting member 220 disposed in the cylindrical main body 210, wherein one end of the cylindrical main body 210 has a first opening 211 for allowing the bin 120 of the upper cover 100 to enter, the opposite end has a second opening 212 for allowing the powder in the bin 120 to pass through after being released, and a plurality of diversion trenches 215 are formed in the sidewall of the cylindrical main body 210.

As shown in fig. 2 to 4, the upper cover body 100 includes a cover main body 110 and a bin 120 for storing powder, the bin 120 includes a bin wall 121 and a sealing film 122, one end of the bin wall 121 is connected with an inner top wall of the cover main body 110, the other end of the bin wall 121 is connected with the sealing film 122, and the sealing film 122 is used for sealing the bin 120;

The end of the bin wall 121, which is far from the top wall of the cover main body 110, is provided with a driving member, and the cutter 200 is provided with a matching member for matching with the driving member;

Initially, the upper cover 100 is detachably covered on the lower ring 300, the cutter 200 is located in the lower ring 300, the driving member and the matching member are mutually matched, one end of the storage bin 120 provided with the sealing film 122 extends into the cylindrical main body 210, and a gap is formed between the sealing film 122 and the cutting member 220;

The bottle cap assembly is opened, the upper cap body 100 moves upwards relative to the lower ring body 300, the driving piece drives the matching piece, the cutter 200 moves upwards relative to the bin 120, the cylindrical main body 210 is gradually sleeved on the outer wall of the bin 120 through the first opening 211 in the upward moving process of the cutter 200, the sealing film 122 is cut by the cutting piece 220 and gradually enters the bin 120, the bin 120 is opened, and powder stored in the bin 120 is released through the second opening 212.

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 powder stored in the bin 120 is put into the liquid in the packaging bottle 10, then the bottle cap assembly is closed, and the packaging bottle 10 is shaken to mix the powder and the liquid sufficiently. During shaking of the packaging bottle 10, liquid may enter the bottle cap assembly. Since the cylindrical body 210 of the cutter 200 is sleeved on the outer wall of the bin 120 after the bottle cap assembly is opened, a gap is formed between the inner wall of the cylindrical body 210 and the outer wall of the bin 120, and since the liquid enters the bottle cap assembly during the process of shaking the packaging bottle 10, the liquid is easily adhered to the inner wall of the cylindrical body 210 under the action of surface tension and the like, and is stored in the gap between the inner wall of the cylindrical body 210 and the outer wall of the bin 120. In the cutter 200 provided in this embodiment, the side wall of the cylindrical main body 210 is provided with the diversion trench 215, so that the liquid entering the gap can be diverted through the diversion trench 215 and rapidly discharged, thereby improving the problem of easy storage of the bottle cap assembly.

Optionally, the diversion trench 215 is a through trench penetrating the sidewall of the cylindrical main body 210. Preferably, the number of the through grooves is plural.

When the diversion trench 215 is a through trench, the liquid remaining between the inner wall of the cylindrical body 210 and the outer wall of the silo 120 is collected in the through trench and discharged out of the cutter 200 through the through trench.

Alternatively, as shown in fig. 3 and 4, the bin 120 is cylindrical, the cutting member 220 is annular, and the inner diameter of the bin 120 is 0.3-1.0 mm larger than the outer diameter of the cutting member 220.

When the bottle cap assembly is opened, the cutter 220 cuts the sealing film 122 open and gradually enters the bin 120, the cut sealing film 122 is gradually clamped between the inner wall of the bin 120 and the outer wall of the cutter 220, and the powder stored in the bin 120 is released through the second opening 212.

When the cap assembly is opened, cutter 200 moves upward from within lower ring 300 to cut seal 122 open and bin 120 opens to allow powder to fall below to mix with liquid. Because the inside diameter of the bin 120 is 0.3-1.0 mm larger than the outside diameter of the cutting member 220, the distance between the bin 120 and the cutting member 220 is 0.3-1.0 mm after the cutter 200 moves upwards, and the gap with the size can ensure that the cut sealing film 122 is clamped in the gap according to the types and the thicknesses of the sealing films 122 common in the market, so that the problem that the sealing film 122 is not easy to enter the gap is avoided, and the phenomenon that the cutter 200 is clamped after the sealing film 122 is cut and the sealing film 122 blocks powder from falling is effectively avoided.

Specifically, the inner diameter of the bin 120 is 0.3-1.0 mm larger than the outer diameter of the cutter 220, such as 0.3mm, 0.4mm, 0.5mm, 0.7mm, 0.8mm, 0.9mm, or 1mm.

Optionally, during the opening of the cap assembly, from the start of screwing to the end of screwing, the sealing film 122 is cut so as not to be completely detached from the silo 120, and a portion of the sealing film 122 is still connected to the end of the silo 120, so as to better ensure that the sealing film 122 is clamped between the cutting member 220 and the silo 120. One of the specific ways of realizing that the sealing film 122 is cut to be not completely separated from the bin 120 is to select a material with a certain toughness as the sealing film 122, so that the sealing film 122 is continuously ruptured at first, and the sealing film 122 is not completely cut due to the pushing-up action of the cutting member 220 and the sealing film 122 is gradually clamped between the bin 120 and the cutting member 220, so that the relative angle between the sealing film 122 and the cutting member 220 is changed, and the cutting member 220 can not continuously cut the sealing film 122 any more, thereby realizing that the sealing film 122 is not completely cut.

Alternatively, the material of the sealing film 122 may be, for example, polyethylene (PE), polyvinyl alcohol (PVOH), polypropylene (PP), polyvinyl acetate (EVA), polyester (PET), aluminum foil, etc.

Alternatively, the thickness of the sealing film 122 is 50 μm to 100 μm, for example 50 μm, 55 μm, 60 μm, 70 μm, 75 μm, 80 μm, 90 μm or 100 μm.

Alternatively, as shown in fig. 3 and 4, 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.

Optionally, as shown in fig. 1, a lower ring body accommodating cavity 150 is enclosed 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 located 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.

Further, as shown in fig. 3 and 4, the inner sidewall of the cap body 110 is provided with a first female screw 111, and the outer wall of the lower ring body 300 is provided with a first male screw 301 that mates with the first female screw 111;

The driving member mentioned above is a second external thread 130, the second external thread 130 is disposed at a position on the outer side of the bin wall 121 near the sealing film 122, the mating member is a second internal thread 213, the second internal thread 213 is disposed on the inner wall of the cylindrical body 210, and the spiral directions of the first internal thread 111 and the second external thread 130 are opposite.

A limiting part 310 for limiting the cutter 200 so that the cutter 200 can only move upward relative to the lower ring 300 is provided in the lower ring 300;

Initially, the upper cover 100 is detachably covered on the lower ring 300 through the cooperation of the first internal thread 111 and the first external thread 301, and the cutter 200 is arranged in the lower ring 300 and limited by the limiting part 310;

The bottle cap assembly is opened, the upper cap body 100 is screwed, the bin wall 121 rotates along the screwing direction of the upper cap body 100, and the cutter 200 moves upwards relative to the upper cap body 100 under the cooperation of the second external thread 130 and the second internal thread 213 due to the fact that the screwing directions of the first internal thread 111 and the second external thread 130 are opposite, so that the cutting member 220 cuts the sealing film 122.

Further, the second internal thread 213 includes at least one first spiral protrusion 213a, at least one first spiral protrusion 213a encloses at least one spiral groove 213b, the second external thread 130 includes at least one second spiral protrusion 131, and at least one spiral groove 213b is matched with at least one second spiral protrusion 131 in a one-to-one correspondence;

The end of each second spiral protrusion 131 near the sealing film 122 is a start end 131a, and initially, the start end 131a of each second spiral protrusion 131 is located in the corresponding spiral groove 213 b.

When the starting end 131a of each second spiral protrusion 131 is located in the corresponding spiral groove 213b, it is well ensured that the compartment wall 121 can hook the cutter 200 when the cover 100 is screwed on, so that the cutter 200 moves upwards together.

It should be noted that, due to the arrangement of the diversion trench 215 on the inner wall of the cylindrical main body 210, each first spiral protrusion 213a is not a continuous protrusion, and the spiral protrusion is broken at the location where the diversion trench 215 is arranged, but even if the first spiral protrusion 213a is broken at a plurality of locations, the mutual cooperation between the spiral groove 213b and the second spiral protrusion 131 is not affected.

Taking the illustrated structure as an example, the number of the first spiral ribs 213a is 3, and the number of the corresponding spiral grooves 213b is 3, and correspondingly, the number of the second spiral ribs 131 is 3.

Further, the first external thread 301 has a first start point, a release point and a first end point, and the first internal thread 111 has a second start point and a second end point;

initially, the position of the first starting point corresponds to the position of the second starting point;

When the upper cover body 100 is unscrewed, the second starting point is located at a position corresponding to the first ending point;

In the process of screwing the upper cap body 100 onto the lower ring body 300, the second starting point moves along the screw direction of the first external screw thread 301, when the second starting point moves to correspond to the disengagement point, the second screw convex strip 131 is completely disengaged from the screw groove 213b, the upper cap body 100 is continuously screwed down, the bin wall 121 moves down, the starting end 131a of the second screw convex strip 131 gradually shows a trend of being pressed into the screw groove 213b along with the downward movement of the bin wall 121, and when the second starting point is screwed to correspond to the first starting point, the starting end 131a of the second screw convex strip 131 is clamped into the screw groove 213b again.

At the moment when the start end 131a of the second spiral protrusion 131 is again caught in the spiral groove 213b, a slight upward jumping motion of the cutter 200 occurs, and the user can also hear a click like "click".

Specifically, in order to achieve complete removal of the second spiral protrusion 131 from the spiral groove 213b, the start end 131a may be engaged again in the spiral groove 213b during screwing and pressing of the upper cover 100, and the condition to be satisfied may be, for example, that at least one of the first spiral protrusion 213a and the second spiral protrusion 131 is made of a material that can be deformed and can be restored immediately after being deformed, or that at least one of the bin wall 121 and the cylindrical body 210 is made of a material that can be deformed and can be restored immediately after being deformed.

Optionally, the material of the first spiral protrusion 213a and/or the second spiral protrusion 131 is HDPE (high density polyethylene) or PP (polypropylene copolymer), and/or the material of the bin wall 121 and/or the cylindrical body 210 is HDPE (high density polyethylene) or PP (polypropylene copolymer).

When the first spiral protrusion 213a, the second spiral protrusion 131, the bin wall 121, or the cylindrical main body 210 are made of the above materials, it is possible to screw the upper cover 100 until the second starting point corresponds to the first starting point (i.e., the upper cover 100 is screwed to the bottom), and the starting section of the second spiral protrusion is again clamped into the spiral groove 213 b.

Alternatively, as shown in fig. 1 to 3, the cutter 220 includes a ring body 240 and at least one cutting blade 221 having a tapered shape, one end of the ring body 240 is connected to the cylindrical body 210 through a connection ring 230, and the other end of the ring body 240 is connected to each cutting blade 221.

The sharp-tapered cutter 221 is easier to pierce the sealing film 122, and the specific arrangement of the blade edge of the cutter 221 makes it possible to easily cut the sealing film 122 having high strength and toughness even if it faces the sealing film, without making significant resistance to screwing of the upper cover body 100.

Alternatively, as shown in fig. 1 to 3, the number of the cutting blades 221 is plural, and the plurality of cutting blades 221 pierce the sealing film 122 from plural positions, thereby enabling the sealing film 122 to be cut more quickly when the cap body 100 is screwed on.
