Hereinafter, a bottle cap and a bottle according to an embodiment of the present invention will be described with reference to the accompanying drawings.

Referring to fig. 1 to 8, a bottle cap 100 according to an embodiment of the first aspect of the present invention includes a bin 300 and a film cutting member 400. The cartridge 300 includes a first body 310 and a sealing film 340, wherein the first body 310 is provided with a receiving groove 320, and the receiving groove 320 is used for storing a solute. The receiving groove 320 has a groove bottom 321 and a notch 322 sequentially arranged in the axial direction of the cartridge 300, and the sealing film 340 is connected to the first body 310 and closes the notch 322, thereby sealing the solute in the receiving groove 320 and preventing the solute from directly contacting the solution. The circumferential outer surface of the first body 310 is provided with a guide groove 330, the guide groove 330 includes a first channel 331 and a second channel 332 communicating with each other, the first channel 331 and the second channel 332 are sequentially arranged in the circumferential direction of the first body 310, the first channel 331 extends obliquely in a direction toward the groove bottom 321 along the notch 322, and the second channel 332 extends in the circumferential direction of the first body 310.

The film cutting member 400 includes a second body 410, a first cutter 440, and a guide post 430, and the film cutting member 400 is provided with a first hole 420 penetrating the second body 410. The first cutting knife 440 and the guide post 430 are both connected to the second body 410 and located in the first hole 420, and along the direction from the groove bottom 321 to the notch 322, the guide post 430 and the first cutting knife 440 are sequentially arranged, and the guide post 430 is slidably connected to the first body 310 and inserted into the guide groove 330. When the guide post 430 moves in the first channel 331, the film cutting member 400 moves in the axial direction of the cartridge 300 under the guidance of the first channel 331 and causes the first cutting knife 440 to come close to the sealing film 340. After the guide post 430 moves to a set position in the first channel 331, the first cutting knife 440 contacts the sealing film 340 and cuts the sealing film 340 along with the movement. After the guide post 430 moves to the second channel 332, the first cutter 440 moves along the circumferential direction of the bin 300, so that the film cutting operation of the sealing film 340 is continued until the sealing film 340 is cut to drop, and the material in the accommodating groove 320 can fall out of the notch 322 of the accommodating groove 320.

It should be noted that, because the storage bin and the bottle body, and the storage bin and the film cutting member rotate relatively, the axial direction of the storage bin is the extending direction of the rotating axis when the storage bin rotates.

The bottle cap 100 of the embodiment of the invention guides the movement of the membrane cutting piece 400 through the matching of the guide groove 330 and the guide post 430, the movement of the membrane cutting piece 400 is not directly related to the thread matching position of the bottle cap 100 and the bottle body 610, and when the bottle cap 100 seals the bottle mouth 630 through threaded connection, the bottle cap 100 and the bottle body 610 are screwed tightly. Compared with the mode that the bottle cap 100 is screwed in along the threads and then is screwed out along the threads to enable the stripping piece to move relative to the sealing film 340 by utilizing the screwing-in direction of the bottle cap 100 in the related art, the bottle cap 100 does not need to be provided with a limiting ring on the bottle body 610, so that a drinker can conveniently strip and uncover the bottle, and the possibility that the limiting ring pollutes the environment is reduced.

The number of the accommodating grooves 320 and the number of the guide pillars 430 are not limited, and the accommodating grooves 320 and the guide pillars are arranged in a one-to-one correspondence manner, so that the stability of the relative movement between the film cutting piece 400 and the storage bin 300 can be improved by the cooperation of the accommodating grooves 320 and the guide pillars. The number of the first cutters 440 is not limited, and the plurality of first cutters 440 can enable the plurality of cutters to simultaneously cut the sealing film 340, so that the minimum relative movement distance required between the film cutting member 400 and the storage bin 300 when the film cutting operation is implemented can be reduced compared with the case that a single first cutter 440 is used for cutting, and the length of the second channel 332 can be reduced.

Further, the first channel 331 and the second channel 332 are connected by an arc surface to achieve a smooth transition, so that the movement of the guide post 430 from the first channel 331 to the second channel 332 is smooth, and the probability of the guide post 430 being stuck or jammed is reduced. Because cut membrane piece 400 and guide pillar 430 when assembling, utilize the deformation of cutting membrane piece 400 to make in guide pillar 430 slide into storage tank 320, in order to reduce the deformation of cutting membrane piece 400 when assembling, reduce the assembly degree of difficulty, the surface of feed bin 300 still is provided with along the easy dress groove 370 of axial extension, easy dress groove 370 communicates with first channel 331, reduce the deformation that takes place when guide pillar 430 supports with the surface of feed bin 300 through easy dress groove 370, make in guide pillar 430 slides into guide way 330 more easily.

Specifically, the first cap 200 and the body 610 are screwed together, so that the cap 100 is screwed to the body 610 to seal the opening of the body 610. Wherein, first lid 200 is provided with first groove 210, and fixed connection can be realized through the mode of bonding or joint to feed bin 300 and first lid 200, and feed bin 300 is located first groove 210, and the rotation through first lid 200 drives the rotation of feed bin 300 to realize feed bin 300 and cut the relative motion between the film element 400.

Further, referring to fig. 1 to 3 and 6, one of the outer surface of the cartridge 300 and the inner surface of the first cover 200 is provided with an annular boss 350, and the other is provided with an annular groove 220, along the circumferential direction of the first body 310, the annular boss 350 being fitted into the annular groove 220. Relative movement of the cartridge 300 and the first cap 200 in the axial direction can be restricted by the snap fit of the annular boss 350 with the annular groove 220. One of the inner surface of the first cover 200 and the outer surface of the cartridge 300 is provided with a limit boss 360, and the other is provided with a first limit groove 230, along the axial direction of the cartridge 300, and the limit boss 360 is embedded in the first limit groove 230. Through the joint cooperation of spacing boss 360 and first spacing groove 230, can restrict the relative rotation of feed bin 300 and first lid 200 to realize together with annular boss 350 and ring channel 220 that feed bin 300 is fixed with the joint of first lid 200, improve the stability of being connected of feed bin 300 and first lid 200, saved the use of glue under the bonding mode. And when the first cover 200 or the bin 300 is defective during manufacturing, the defective parts can be replaced, thereby reducing the cost increase caused by defective products.

Also can directly carry out threaded connection with body 610 through feed bin 300 between bottle lid 100 and the body 610, at this moment, feed bin 300 has the second connecting portion 550 of connecting in first main part 310, and the structure of second connecting portion 550 and first lid 200 is the same, and feed bin 300 can be regarded as first lid 200 and first main part 310 shaping structure as an organic whole, through carrying out the application of force to feed bin 300, can make feed bin 300 rotate for body 610, screw up and unscrew bottle lid 100.

When the first cutter 440 is cutting the film, since the first cutter 440 moves toward the bottom 321 of the containing groove 320 to perform the film piercing operation, and then performs the flat cutting on the sealing film 340 along the circumferential direction of the bin 300, the sealing film 340 is cut, and the sealing film 340 is tilted upward toward the bottom 321 of the containing groove 320 without sagging toward the separation direction of the material, which affects the falling of the solute in the containing groove 320. In order to solve the above problem, embodiments of the present invention also provide an improvement. Referring to fig. 5 and 6, the guide groove 330 further includes a third groove 333, the third groove 333 is communicated with the second groove 332, the first groove 331, the second groove 332, and the third groove 333 are sequentially disposed along the circumferential direction of the first main body 310, and the third groove 333 extends obliquely along a direction in which the first cutting knife 440 deviates from the groove bottom 321 of the receiving groove 320. Through the third channel 333, after the first cutter 440 performs the flat cutting operation on the sealing film 340, the guide post 430 slides to the third channel 333 from the second channel 332, at the moment, the first cutter 440 moves along the direction of the groove bottom 321 deviating from the accommodating groove 320 along with the movement of the guide post 430, the first cutter 440 applies a force to the sealing film 340 in the direction deviating from the groove bottom 321 of the accommodating groove 320, so that the film pressing operation is performed on the sealing film 340, the sealing film 340 is pulled in the direction deviating from the groove bottom 321 of the accommodating groove 320, the drooping probability of the sealing film 340 towards the separation direction of the material is improved, and the success rate of the correct falling of the material is improved.

It is understood that the second slot 332 and the third slot 333 may also be connected by an arc surface to achieve a smooth transition, so that the movement of the guide post 430 from the second slot 332 to the third slot 333 is smooth, and the probability of the guide post 430 being jammed or stuck is reduced.

As a further improvement of the above, referring to fig. 7 and 8, the first cutting blade 440 includes a third body 441, a first blade 442, and a second blade 443, the third body 441 is connected to the second body 410, the first blade 442 and the second blade 443 are both connected to the third body 441, and in the circumferential direction of the first body 310, the first blade 442 and the second blade 443 each extend in the direction from the first slot 331 to the second slot 332, wherein the first blade 442 extends longer than the second blade 443, and the first blade 442 and the second blade 443 are sequentially disposed in the direction from the slot bottom 321 toward the slot 322. During the movement of the guide post 430 in the first channel 331 toward the second channel 332, the first knife 442 first contacts the sealing film 340 to pierce and cut the film. When the guide post 430 moves to the second channel 332, the first blade 442 moves to a side of the sealing film 340 adjacent to the groove bottom 321 of the receiving groove 320, and the second blade 443 contacts the sealing film 340 to perform a flat cutting. When the guide post 430 moves to the third slot 333, the first blade 442 moves in a direction away from the bottom 321 of the receiving groove 320, and the bottom surface of the first blade 442 contacts the sealing film 340 to perform a film pressing operation. Compared with the method that the sealing film 340 is driven by the friction of the cutting edge of the first cutter 440, the film pressing is performed on the sealing film 340 through the bottom surface of the first cutter 442, so that the base area of the end surface, facing the bottom 321 of the accommodating groove 320, of the first cutter 442 and the sealing film 340 can be increased, the probability that the sealing film 340 sags in the separation direction of the material is further increased, and the success rate of the correct falling of the material is increased.

The present invention also provides an embodiment of the first aspect of the bottle 600, and referring to fig. 1 and fig. 2, the bottle 600 includes the bottle cap 100 and the bottle body 610 in the embodiment of the first aspect. The bottle body 610 has a receiving cavity 620 and a bottle mouth 630 communicating with the receiving cavity 620, the bottle cap 100 seals the bottle mouth 630, and the bottle cap 100 is in threaded connection with the bottle body 610. By applying the bottle cap 100 according to the embodiment of the first aspect of the present invention, the movement of the film cutting member 400 can be guided by the engagement of the guide groove 330 and the guide post 430, so that the film cutting operation of the sealing film 340 by the film cutting member 400 is realized. Compared with the screwing direction of the bottle cap 100 in the related art, the bottle cap 100 is screwed in along the threads firstly and then screwed out along the threads so that the stripping piece moves relative to the sealing film 340, a limiting ring does not need to be arranged on the bottle body 610, so that a drinker can conveniently strip and uncover the bottle, and the possibility of environmental pollution caused by the limiting ring is reduced.

When a drinker applies force to rotate the bottle cap 100 away from the bottle body 610 and the bin 300 and the film cutting member 400 rotate relatively, the film cutting member 400 rotates along with the rotation of the bin 300 due to friction generated by the contact between the guide post 430 and the wall of the guide groove 330, and the guide post 430 can move correctly along the guide groove 330 only by increasing the rotation speed of the bin 300 and adjusting the inclination angles of the first channel 331 and the third channel 333. In order to solve the above problem, referring to fig. 1, 4 and 7, the inner surface of the bottle body 610 is provided with a second limiting block 640, the circumferential outer surface of the film cutting member 400 is provided with a limiting tooth 460, the second limiting block 640 abuts against the limiting tooth 460, when the film cutting member 400 rotates along with the bin 300 due to friction, the second limiting block 640 contacts with the limiting tooth 460, so as to limit the rotation of the film cutting member 400, so that the guide post 430 can smoothly move along the guide groove 330, and the film cutting stability of the film cutting member 400 is improved.

It can be understood that when the guide post 430 moves to the end of the third channel 333, the guide post 430 will abut against the wall of the third channel 333, so as to drive the film cutting member 400 to rotate together with the storage bin 300, and at this time, if the second limit block 640 continues to abut against the limit tooth 460, the rotation of the storage bin 300 will be limited together, and the bottle cap 100 will not move continuously along the thread of the bottle body 610, resulting in being difficult to separate from the bottle body 610. Because the bottle cap 100 gradually keeps away from the bottle body 610 along the axial direction in the screwing-out process, the limiting teeth 460 just rise along with the whole movement of the bottle cap 100 to be separated from the support of the second limiting block 640 when the guide post 430 reaches the end of the third channel 333 by controlling the axial arrangement positions of the limiting teeth 460, the second limiting block 640, the guide post 430 and the guide groove 330, so that the whole bottle cap 100 can be smoothly screwed off the bottle body 610 along the thread of the bottle body 610.

Or, further, referring to fig. 1, 4 and 7, in the circumferential direction of the film cutting member 400, the limiting tooth 460 extends obliquely relative to the outer surface of the film cutting member 400 in the direction from the second groove 332 to the first groove 331, so that the limiting tooth 460 is more easily deformed when abutting against the second limiting block 640. The cross-sectional area of the second stopper 640 gradually decreases along the direction close to the film cutting member 400, so that both side surfaces of the second stopper 640 in the circumferential direction of the first body 310 are inclined surfaces, and the deformation guide is performed on the stopper teeth 460. When a user rotates the bottle cap 100 away from the bottle body 610, the limiting teeth 460 abut against the second limiting block 640, and move along with the guiding inclined plane and deform, so as to pass over the second limiting block 640. Due to the influence of the extending direction of the limiting tooth 460, the limiting tooth 460 deforms to pass through the second limiting block 640, which requires the drinker to apply a large force to the bottle cap 100, and therefore, the action of the limiting tooth 460 deforming to pass through the second limiting block 640 will occur after the guide post 430 moves to the end of the third channel 333, which will not affect the correct movement of the guide post 430 in the guide groove 330.

When a drinker rotates the bottle cap 100 away from the bottle body 610 and drives the storage bin 300 and the film cutting member 400 to rotate relatively, because the limiting teeth 460 extend obliquely relative to the outer surface of the film cutting member 400 along the direction from the second channel 332 to the first channel 331, when the film cutting member 400 rotates along with the storage bin 300 due to friction, the second limiting block 640 contacts with the top end of the extending limiting teeth 460, so as to limit the rotation of the film cutting member 400, so that the guide post 430 can smoothly move along the guide groove 330, and the film cutting stability of the film cutting member 400 is improved. When a user wants to seal the bottle cap 100 by replacing the bottle cap 100, the bottle cap 100 is rotated in the reverse direction to screw the bottle cap 100 onto the bottle body 610, and at this time, the second stopper 640 and the stopper tooth 460 are pressed against each other along the extending direction of the stopper tooth 460, so that the stopper tooth 460 can be deformed by a small driving force and the bottle cap 100 can be screwed onto the bottle body 610 again by the second stopper 640.

Or, as another modification, the guide groove 330 further includes a fifth groove channel, the fifth groove channel is communicated with the third groove channel 333, the fifth groove channel extends along the circumferential direction of the first main body 310, and the first groove channel 331, the second groove channel 332, the third groove channel 333 and the fifth groove channel are sequentially arranged along the circumferential direction of the first main body 310, so that the guide pillar 430 can continue to move in the fifth groove channel after moving to the end of the third groove channel 333, the film cutting member 400 continues to rotate along with the guide pillar 430, but the relative position of the film cutting member 400 and the cartridge 300 in the axial direction is unchanged until finally following the cartridge 300 to be separated from the bottle body 610.

In the above scheme, the second limit block 640 is arranged on the inner surface of the bottle body 610, so that the limit teeth 460 cooperate to limit the unidirectional rotation of the film cutting member 400. However, the second limiting block 640 is disposed on the bottle body 610, and process adjustment is required to be performed during production of the bottle body 610, and when the structure of the bottle cap 100 is changed, the bottle body 610 may also need to be changed, but the production of the bottle body 610 and the production of the bottle cap 100 are usually separated, which brings inconvenience to production and research and development.

In order to solve the above problems, in a second aspect of the present invention, there is provided a bottle cap 100, and referring to fig. 9 to 16, in addition to the first cap 200, the bottle cap 100 further includes a second cap 500, the second cap 500 includes a fourth body 510, the second cap 500 is provided with a second hole 520 penetrating through the fourth body 510, an inner surface of the fourth body 510 is provided with an internal thread 530, the internal thread 530 is used for being screwed with a bottle body 610, and the second cap 500 is rotatably connected to the inner surface of the first cap 200. Through the rotational connection between the second cover 500 and the first cover 200, the first cover 200 can drive the bin 300 to move under the in-situ rotation motion, so that the relative motion between the bin 300 and the film cutting member 400 is realized. Threaded connection of second lid 500 and body 610 has realized the whole threaded connection with body 610 of bottle lid 100, and the size of the internal thread 530 of second lid 500 is matchd with most general body 610, can realize threaded connection with most general body 610, the lectotype restriction to body 610 is little, and when needs carry out structural modification, directly change second lid 500 can, the structure that will mutually support all sets up on bottle lid 100 is whole, the cost of structural modification has been reduced.

Further, in order to limit the rotation of the film cutting member 400, referring to fig. 9, 12 and 16, the film cutting member 400 further includes a first limit block 450, the first limit block 450 is connected to the circumferential outer surface of the second main body 410, the inner surface of the second cover 500 is further provided with a second limit groove 570 extending in the axial direction of the cartridge 300, and the first limit block 450 is inserted into the second limit groove 570. The first limiting block 450 is supported by the second limiting groove 570, so that the film cutting piece 400 can be limited to rotate relative to the second cover 500, the guide pillar 430 cannot rotate along with the bin 300 when moving in the guide groove 330, the relative rotation between the bin 300 and the film cutting piece 400 is realized by the rotation of the bin 300, the relative movement between the bin 300 and the film cutting piece 400 in the axial direction is realized by the film cutting piece 400, and the film cutting operation of the film cutting piece 400 on the sealing film 340 is realized.

As a modification of the above, referring to fig. 9, 15 and 16, the second cover 500 further includes a partition plate 540, the sealing film 340 and the partition plate 540 being disposed in order along the groove bottom 321 toward the notch 322, the partition plate 540 being attached to the inner surface of the second cover 500 and closing the second hole 520. By providing the isolation plate 540, the solution can be further isolated from the solute, the possibility of contact between the solution and the container is further reduced, and the sealing performance to the solute is increased. The partition 540 is further provided with a knife-hiding groove 561 extending along the circumferential direction, and the knife-hiding groove 561 is disposed on one side of the partition 540 facing the first cover 200 and is recessed in a direction away from the first cover 200. The first cap 200 further includes a second cutter 240, the second cutter 240 having a connecting end 241 and a blade end 242, the connecting end 241 being connected to the groove bottom 321 of the accommodating groove 320, the blade end 242 extending in a direction toward the partition 540 and being at least partially located in the blade groove 561. The second cutter 240 can rotate when the first cover 200 and the second cover 500 rotate relatively, thereby performing a cutting action. The blade end 242 of the second cutter 240 is located in the knife groove 561 when the first cap 200 is not rotated, thereby ensuring the integrity of the sealing plate of the bottle 600 in an unopened state. And the hidden blade groove 561 is recessed in a direction away from the first cover 200, and when the second cutter 240 cuts, the part of the partition plate 540 except the hidden blade groove 561 can be cut in the circumferential direction, thereby realizing the cutting of the partition plate 540.

Further, in order to improve the cutting efficiency of the second cutting knife 240, the embodiment of the present invention provides an improvement. Referring to fig. 16, the partition 540 includes a connecting portion 550 and a knife hiding portion 560 connected to each other, the connecting portion 550 is connected to the inner surface of the second cover 500, a knife hiding groove 561 is formed in the knife hiding portion 560, and the blade end 242 protrudes from an end surface of the connecting portion 550 on a side away from the first cover 200 in a direction away from the first cover 200. By controlling the length of the blade end 242, the blade protrudes from the end surface of the connecting portion 550 on the side away from the first cover 200, so that when the second cutter 240 cuts the connecting portion 550 of the isolation plate 540, the connecting portion 550 can be directly cut through, thereby improving the cutting efficiency of the second cutter 240. The number of times the second cutter 240 cuts the insulation sheet 540 is reduced.

It can be understood that by extending the extension lengths of the first, second and third slots 331, 332 and 333 on the circumferential outer surface of the first body 310, it is ensured that the first cutter 440 completes the cutting of the partition 540 by the second cutter 240 at the same time as the film-piercing is completed. The cutting action of the first cutter 440, particularly the sealing film 340, can be achieved by adjusting the slope of the first and second channels 331 and 332 with respect to the second channel 332 and the extension length of the first, second and third channels 331, 332 and 333.

It can be understood that when the guide post 430 moves to the end of the third slot 333 and abuts against the slot wall of the third slot 333, the film cutting member 400 will drive the second cap 500 to move together due to the abutting of the first limiting block 450 and the slot wall of the second limiting slot 570, so as to screw the second cap 500 off the bottle body 610 along the thread of the bottle body 610.

Further, since the second cutting blade 240 is required to apply a certain rotational force to the first cap 200 when the partition 540 is cut by the user, particularly, a force required to be applied by the user is relatively large with respect to a force required to be applied by a subsequent cutting operation when the partition 540 is initially cut. And the stud moves within the first and third channels 331 and 333, the resistance applied to the guide post 430 is greater than that of the second channel 332 because the first and third channels 331 and 333 are inclined. Embodiments of the present invention also provide an improvement in order to reduce the force required by the consumer to apply to the closure 100 and facilitate opening of the closure 100. Referring to fig. 13 and 14, the guide groove 330 further includes a fourth channel 334, the fourth channel 334 extends along the circumferential direction of the first body 310, the fourth channel 334 communicates with the first channel 331, and the fourth channel 334, the first channel 331 and the second channel 332 are sequentially disposed along the circumferential direction of the first body 310. Alternatively, the fourth groove 334 is communicated with the first groove 331 on the basis of the third groove 333, and the fourth groove 334, the first groove 331, the second groove 332, and the third groove 333 are sequentially arranged in the circumferential direction of the first body 310. By arranging the fourth channel 334, the guide post 430 moves in the fourth channel 334 along the circumferential direction of the first main body 310 before entering the first channel 331, so that the film cutting member 400 and the magazine 300 rotate relatively and the relative position in the axial direction is unchanged.

By arranging the fourth channel 334, the guide post 430 moves in the fourth channel 334 along the circumferential direction of the first main body 310 before entering the first channel 331, so that the film cutting member 400 and the storage bin 300 rotate relatively and the relative position in the axial direction is unchanged. After the second cutter 240 performs a cutting operation on the isolation plate 540 for a period of time, the first cutter 440 performs a film cutting operation on the sealing film 340, so that the larger resistance which needs to be overcome when the second cutter 240 starts to cut the isolation plate 540 and the larger resistance which needs to be overcome when the guide post 430 moves along the first channel 331 and the second channel 332 are dispersed, the maximum driving force required for screwing the bottle cap 100 is reduced, and a user can conveniently screw the bottle cap 100.

The invention also provides a bottle 600 of a second aspect embodiment, which comprises the bottle cap 100 of the second aspect embodiment, and further comprises a bottle body 610, which is provided with a containing cavity 620 and a bottle mouth 630 communicated with the containing cavity 620, wherein the bottle cap 100 seals the bottle mouth 630, and the second cover 500 is rotatably connected with the bottle body 610. By applying the bottle cap 100 according to the embodiment of the second aspect of the present invention, the movement of the film cutting member 400 can be guided by the engagement of the guide groove 330 and the guide post 430, so that the film cutting operation of the sealing film 340 by the film cutting member 400 is realized. Compared with the screwing direction of the bottle cap 100 in the related art, the bottle cap 100 is screwed in along the threads firstly and then screwed out along the threads so that the stripping piece moves relative to the sealing film 340, a limiting ring does not need to be arranged on the bottle body 610, so that a drinker can conveniently strip and uncover the bottle, and the possibility of environmental pollution caused by the limiting ring is reduced. On the basis, the second cover 500 is matched with the threads of most of the universal bottle bodies 610, so that the requirement on the structure of the bottle bodies 610 when the bottle cap 100 achieves the membrane cutting function is reduced, and the applicability of the bottle cap 100 is improved.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
