The bottle cap and the bottle according to the embodiments of the present utility model are described below with reference to the drawings.

Referring to fig. 1 to 8, a bottle cap 100 according to an embodiment of the first aspect of the present utility model includes a bin 300 and a film cutting member 400. The cartridge 300 includes a first body 310 and a sealing membrane 340, wherein the first body 310 is provided with a receiving groove 320, and the receiving groove 320 is used for storing solute. The receiving groove 320 has a groove bottom 321 and a groove opening 322 sequentially disposed along an axial direction of the cartridge 300, and the sealing film 340 is connected to the first body 310 and closes the groove opening 322, thereby sealing the solute in the receiving groove 320, preventing the solute from directly contacting the solution. The outer surface of the circumference 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 which are communicated with each other, the first channel 331 and the second channel 332 are sequentially arranged along the circumference of the first body 310, the first channel 331 extends obliquely along the direction of the notch 322 toward the groove bottom 321, and the second channel 332 extends along the circumference 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 cutter 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 of the groove bottom 321 towards the groove opening 322, the guide post 430 and the first cutter 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 guide of the first channel 331, and the first cutter 440 is gradually brought close to the sealing film 340. After the guide post 430 moves to a set position in the first channel 331, the first cutter 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 continuously performed until the sealing film 340 is cut to drop, so that the material in the accommodating groove 320 can drop out of the notch 322 of the accommodating groove 320.

The axial direction of the bin is the extending direction of the rotation axis when the bin rotates because the bin and the bottle body and the bin and the film cutting piece rotate relatively.

In the embodiment of the utility model, the bottle cap 100 guides the movement of the film cutting member 400 through the cooperation of the guide groove 330 and the guide post 430, the movement of the film cutting member 400 has no direct relation with the threaded cooperation 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 to the related art in which the bottle cap 100 is screwed in along the screw thread and then unscrewed along the screw thread to move the stripper relative to the sealing film 340, the bottle cap 100 of the present utility model does not require a stop collar on the bottle body 610, thereby facilitating the stripping and uncapping operations of the drinker and reducing the possibility of environmental pollution caused by the stop collar.

The number of the accommodating grooves 320 and the guide posts 430 is not limited, and the accommodating grooves 320 and the guide posts 430 are arranged in one-to-one correspondence, and the matching of the pairs of accommodating grooves 320 and the resulting guide posts can improve the stability of the relative movement of the film cutting member 400 and the stock bin 300. The number of the first cutters 440 is not limited, and the plurality of first cutters 440 may be configured such that the plurality of cutters simultaneously cut the sealing film 340, compared to a case where a single first cutter 440 cuts, a minimum relative movement distance required between the film cutting member 400 and the magazine 300 in a case where a film cutting operation is performed may be reduced, thereby reducing the length of the second channel 332.

Further, the first channel 331 and the second channel 332 are connected through an arc surface to realize smooth transition, so that the guide post 430 moves smoothly from the first channel 331 to the second channel 332, and the probability of jamming or locking of the guide post 430 is reduced. Because when cutting membrane piece 400 and guide pillar 430 are assembled, the deformation of cutting membrane piece 400 is utilized to make guide pillar 430 slide into accommodating groove 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 is still provided with along the easy dress groove 370 of axial extension, easy dress groove 370 communicates with first channel 331, reduces the deformation that takes place when guide pillar 430 supports with the surface of feed bin 300 through easy dress groove 370, makes guide pillar 430 slide into guide groove 330 more easily.

Specifically, the first cap 200 can be screwed to the body 610 between the cap 100 and the body 610, so that the cap 100 is screwed to the body 610 to seal the opening of the body 610. Wherein, the first cover 200 is provided with a first groove 210, the bin 300 and the first cover 200 can be fixedly connected in a bonding or clamping manner, and the bin 300 is located in the first groove 210, and the bin 300 is driven to rotate by the rotation of the first cover 200, so as to realize the relative movement between the bin 300 and the film cutting member 400.

Further, referring to fig. 1 and fig. 3, 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 along the circumferential direction of the first body 310, the other is provided with an annular groove 220, and the annular boss 350 is embedded in the annular groove 220. The relative movement of the cartridge 300 and the first cover 200 in the axial direction can be restricted by the snap fit of the annular boss 350 with the annular groove 220. Along the axial direction of the bin 300, one of the inner surface of the first cover 200 and the outer surface of the bin 300 is provided with a limit boss 360, the other is provided with a first limit groove 230, 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 the joint of feed bin 300 and first lid 200 together with annular boss 350 and ring channel 220 fixed, improve the connection stability 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, defective components can be replaced, so that the cost increase caused by defective products is reduced.

The bottle cap 100 and the body 610 may be directly screwed to the body 610 through the bin 300, at this time, the bin 300 has the second connection portion 550 connected to the first body 310, the second connection portion 550 and the first cap 200 have the same structure, the bin 300 may be regarded as an integral structure formed by the first cap 200 and the first body 310, and the bin 300 may be rotated relative to the body 610 by applying a force to the bin 300, so as to screw and unscrew the bottle cap 100.

When the first cutter 440 cuts the film, the first cutter 440 moves towards the bottom 321 of the accommodating groove 320 to perform film punching operation, then makes a flush cut on the sealing film 340 along the circumferential direction of the bin 300, and after the sealing film 340 is cut, a certain probability exists that the sealing film warps upwards towards the bottom 321 of the accommodating groove 320 and does not sag towards the separating direction of the material, so that the falling of the solute in the accommodating groove 320 is affected. In order to solve the above-described problems, embodiments of the present utility model 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 a circumferential direction of the first body 310, and the third groove 333 extends obliquely in a direction in which the first cutter 440 is away from the groove bottom 321 of the accommodating groove 320. Through setting up third channel 333 for first cutter 440 is carrying out the butt operation back to sealing membrane 340, guide pillar 430 slides to third channel 333 from second channel 332, and first cutter 440 follows the motion of guide pillar 430 this moment, along the direction motion of deviating from the tank bottom 321 of storage tank 320, first cutter 440 applys the force of the direction of deviating from the tank bottom 321 of storage tank 320 to sealing membrane 340 to carry out the press mold operation to sealing membrane 340, pull sealing membrane 340 to the direction of deviating from the tank bottom 321 of storage tank 320, improve the probability that sealing membrane 340 droops towards the separation direction of material, improve the success rate that the material correctly falls.

It can be appreciated that the second channel 332 and the third channel 333 may be connected by an arc surface to achieve a smooth transition, so that the guide post 430 moves smoothly from the second channel 332 to the third channel 333, and the probability of the guide post 430 getting stuck or dead is reduced.

As a further improvement of the above, referring to fig. 7 and 8, the first cutter 440 includes a third body 441, a first cutter 442, and a second cutter 443, the third body 441 is connected to the second body 410, the first cutter 442 and the second cutter 443 are connected to the third body 441, and in the circumferential direction of the first body 310, the first cutter 442 and the second cutter 443 extend in the direction from the first channel 331 to the second channel 332, wherein the first cutter 442 has an extension length greater than that of the second cutter 443, and the first cutter 442 and the second cutter 443 are sequentially disposed in the direction of the groove bottom 321 toward the groove opening 322. During movement of the guide post 430 within the first channel 331 toward the second channel 332, the first knife 442 first contacts the sealing membrane 340 to pierce and cut the membrane. When the guide post 430 moves to the second channel 332, the first blade 442 moves to a side of the sealing film 340 near the groove bottom 321 of the accommodating groove 320, and the second blade 443 makes contact with the sealing film 340 to make a flush cut. When the guide post 430 moves to the third channel 333, the first blade 442 moves in a direction away from the groove bottom 321 of the accommodating groove 320, and at this time, the bottom surface of the first blade 442 contacts the sealing film 340 for film pressing operation. Compared with the method that the sealing film 340 is driven by friction of the cutting edge of the first cutter 440, the sealing film 340 is pressed by the bottom surface of the first cutter 442, so that the basic area of the first cutter 442 and the sealing film 340 towards the end surface of the groove bottom 321 of the accommodating groove 320 can be increased, the probability that the sealing film 340 sags downwards towards the separation direction of materials is further increased, and the success rate of the materials falling correctly is further increased.

The present utility model also provides an embodiment of a first aspect of a bottle 600, referring to fig. 1 and 2, the bottle 600 includes the bottle cap 100 and the bottle body 610 in the above embodiment of the first aspect. The body 610 has a receiving cavity 620 and a mouth 630 communicating with the receiving cavity 620, the cap 100 seals the mouth 630, and the cap 100 is screw-coupled with the body 610. By applying the bottle cap 100 according to the first aspect of the present utility model, the movement of the film cutting member 400 can be guided by the cooperation of the guide groove 330 and the guide post 430, thereby achieving the film cutting operation of the film cutting member 400 on the sealing film 340. Compared with the prior art in which the screwing-in direction of the bottle cap 100 is utilized, the bottle cap 100 is screwed in along the screw thread first and then screwed out along the screw thread so that the stripping member moves relative to the sealing film 340, a limiting ring is not required to be arranged on the bottle body 610, thus facilitating the stripping and uncapping operations of drinkers and reducing the possibility of environmental pollution caused by the limiting ring.

When the drinker applies force to rotate the bottle cap 100 away from the bottle body 610 and rotates the bin 300 and the film cutting member 400 relatively, the film cutting member 400 rotates along with the rotation of the bin 300 due to friction force generated by the contact between the guide post 430 and the groove 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 and third grooves 331 and 333. In order to solve the above problems, 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, thereby limiting the rotation of the film cutting member 400, and the guide post 430 can smoothly move along the guide groove 330, so that the film cutting stability of the film cutting member 400 is improved.

It can be appreciated that when the guide post 430 moves to the end of the third channel 333, the guide post 430 abuts against the wall of the third channel 333, so as to drive the film cutting member 400 to rotate with the bin 300, and if the second limiting block 640 continues to abut against the limiting teeth 460, the rotation of the bin 300 is limited, so that the bottle cap 100 is difficult to continue to move along the thread of the bottle body 610, and is difficult to separate from the bottle body 610. Because the bottle cap 100 is gradually far away from the bottle body 610 along the axial direction in the unscrewing process, by controlling the setting positions of the limiting teeth 460, the second limiting block 640, the guide post 430 and the guide slot 330 in the axial direction, when the guide post 430 reaches the end of the third slot 333, the limiting teeth 460 just rise to be separated from the abutting with the second limiting block 640 along the integral movement of the bottle cap 100, so that the bottle cap 100 can be smoothly unscrewed from 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 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, so that the limiting teeth 460 are more easily deformed when abutting against the second limiting block 640. The cross-sectional area of the second stopper 640 is gradually reduced in a direction approaching the film cutting member 400, so that both sides of the second stopper 640 in the circumferential direction of the first body 310 are inclined surfaces to deformation guide the stopper teeth 460. When the drinker rotates the bottle cap 100 away from the bottle body 610 and the limiting teeth 460 are propped against the second limiting block 640, the drinker can move along with the guiding inclined plane and deform, so as to cross the second limiting block 640. Because the extending direction of the limiting teeth 460 is affected, the limiting teeth 460 deform beyond the second limiting block 640 to apply a larger force to the bottle cap 100, so that the action of the limiting teeth 460 deforming beyond the second limiting block 640 can occur after the guide post 430 moves to the end of the third channel 333, and the correct movement of the guide post 430 in the guide slot 330 is not affected.

When a drinker rotates the bottle cap 100 away from the bottle body 610 and drives the bin 300 and the film cutting member 400 to rotate relatively, 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, and when the film cutting member 400 rotates along with the bin 300 due to friction, the second limiting block 640 contacts with the top end extending from the limiting teeth 460, so as to limit the rotation of the film cutting member 400, and the guide post 430 can smoothly move along the guide groove 330, thereby improving the film cutting stability of the film cutting member 400. When the drinker wants to cover the bottle cap 100 for sealing, the bottle cap 100 is reversely rotated to screw the bottle cap 100 on the bottle body 610 through the screw thread, and at this time, the second limiting block 640 and the limiting teeth 460 are in the extending direction of the limiting teeth 460, so that the limiting teeth 460 can deform under a smaller driving force to pass through the second limiting block 640, and the bottle cap 100 can be screwed on the bottle body 610 again.

Alternatively, as another improvement, the guide slot 330 further includes a fifth channel, the fifth channel is communicated with the third channel 333, the fifth channel extends along the circumferential direction of the first main body 310, and the first channel 331, the second channel 332, the third channel 333 and the fifth channel are sequentially arranged along the circumferential direction of the first main body 310, so that after the guide post 430 moves to the end of the third channel 333, the movement of the film cutting member 400 can be continued in the fifth channel, the film cutting member 400 rotates along with the guide post 430, but the relative position of the film cutting member 400 and the storage bin 300 in the axial direction is unchanged until the film cutting member is finally separated from the bottle body 610 along with the storage bin 300.

In the above-mentioned scheme, the second stopper 640 is provided on the inner surface of the bottle body 610, so that the restriction of the unidirectional rotation of the film cutting member 400 is realized in cooperation with the stopper teeth 460. However, the second stopper 640 is disposed on the bottle body 610, and the process needs to be adjusted during the 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 bottle cap 100 is usually separated, which brings inconvenience to the production and development.

In order to solve the above problems, the second aspect of the present utility model further provides a bottle cap 100, and referring to fig. 9 to 16, the bottle cap 100 further includes a second cap 500, the second cap 500 including a fourth body 510, the second cap 500 being provided with a second hole 520 penetrating the fourth body 510, an inner surface of the fourth body 510 being provided with an internal thread 530, the internal thread 530 being for screw-coupling with a body 610, the second cap 500 being rotatably coupled to an 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 rotational movement, thereby realizing the relative movement between the bin 300 and the film cutting member 400. The threaded connection of the second cover 500 and the bottle body 610 realizes the threaded connection of the whole bottle cap 100 and the bottle body 610, and the size of the internal thread 530 of the second cover 500 is matched with that of most of the general bottle bodies 610, so that the threaded connection can be realized with most of the general bottle bodies 610, the shape selection limit of the bottle bodies 610 is small, and when the structure is required to be changed, the second cover 500 is directly changed, the mutually matched structures are arranged on the whole bottle cap 100, and the cost of the structure change is 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 stopper 450, the first stopper 450 is connected to the circumferential outer surface of the second body 410, the inner surface of the second cover 500 is further provided with a second stopper groove 570 extending along the axial direction of the cartridge 300, and the first stopper 450 is inserted into the second stopper groove 570. The second limiting groove 570 is used for supporting the first limiting block 450, so that the rotation of the film cutting piece 400 relative to the second cover 500 can be limited, the guide pillar 430 cannot rotate along with the storage bin 300 when moving in the guide groove 330, the relative rotation of the storage bin 300 and the film cutting piece 400 is realized by the rotation of the storage bin 300, the relative movement of the storage 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 barrier 540, the sealing film 340 and the barrier 540 being sequentially disposed along the groove bottom 321 toward the groove opening 322, the barrier 540 being coupled to the inner surface of the second cover 500 and closing the second hole 520. By providing the separator 540, the solution can be further separated from the solute, the possibility of contact between the solution and the container can be further reduced, and the sealing property against the solute can be increased. The partition plate 540 is further provided with a cutter hiding groove 561 extending in a circumferential direction, and the cutter hiding groove 561 is provided at a side of the partition plate 540 facing the first cover 200 and is recessed in a direction facing away from the first cover 200. The first cover 200 further includes a second cutter 240, the second cutter 240 having a connection end 241 and a blade end 242, the connection 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 plate 540 and being at least partially located in the blade hiding groove 561. The second cutter 240 is capable of rotating with the first cover 200 and the second cover 500 when they are rotated relative to each other, thereby performing a cutting operation. The blade end 242 of the second cutter 240 is positioned in the cutter hiding groove 561 when the first cap 200 is not rotated, thereby ensuring the integrity of the sealing plate of the bottle 600 in the unopened state. And the cutter hiding groove 561 is recessed in a direction away from the first cover 200, and when the second cutter 240 performs cutting, a portion of the separation plate 540 other than the cutter hiding groove 561 can be cut in a circumferential direction, thereby cutting the separation plate 540.

Further, in order to increase the cutting efficiency of the second cutter 240, an embodiment of the present utility model provides an improvement. Referring to fig. 16, the partition plate 540 includes a connection part 550 and a cutter hiding part 560 connected to each other, the connection part 550 is connected to the inner surface of the second cover 500, a cutter hiding groove 561 is provided at the cutter hiding part 560, and the blade end 242 protrudes from an end surface of one side of the connection part 550 facing away from the first cover 200 in a direction facing away from the first cover 200. By controlling the length of the blade end 242 so that the blade protrudes from the end surface of the side of the connection portion 550 away from the first cover 200, it is possible to ensure that the connection portion 550 can be cut through directly when the second cutter 240 cuts the connection portion 550 of the partition plate 540, thereby improving the cutting efficiency of the second cutter 240. The number of times the second cutter 240 cuts the separator 540 is reduced.

It will be appreciated that by extending the lengths of the first, second and third grooves 331, 332, 333 on the circumferential outer surface of the first body 310, it is ensured that the first cutter 440 completes the cutting of the separator 540 by the second cutter 240 while the punching is completed. The cutting action of the first cutter 440 on the sealing film 340 can be achieved by adjusting the slopes of the first and second channels 331 and 332 with respect to the second channel 332 and the extension lengths of the first, second and third channels 331, 332 and 333.

It can be appreciated 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 drives the second cover 500 to move together due to the abutting between the first limiting block 450 and the slot wall of the second limiting slot 570, so as to screw the second cover 500 away from the bottle body 610 along the screw thread of the bottle body 610.

Further, since the second cutter 240 cuts the separation plate 540, it is necessary that the drinker applies a certain rotational force to the first cover 200, and particularly, when the separation plate 540 is cut just at the beginning, the force required to be applied by the drinker is large with respect to the force required to be applied by the subsequent cutting action. And 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 sloped as the posts move within the first and third channels 331 and 333. Embodiments of the present utility model also provide an improvement in facilitating the opening of the closure 100 in order to reduce the force that the user needs to apply to the closure 100. Referring to fig. 13 and 14, the guide groove 330 further includes a fourth channel 334, the fourth channel 334 extending along the circumferential direction of the first body 310, the fourth channel 334 being in communication with the first channel 331, the fourth channel 334, the first channel 331 and the second channel 332 being sequentially disposed along the circumferential direction of the first body 310. Alternatively, the fourth channel 334 is communicated with the first channel 331, and the fourth channel 334, the first channel 331, the second channel 332, and the third channel 333 are sequentially disposed along the circumferential direction of the first body 310, on the basis that the third channel 333 is disposed. By providing the fourth channel 334, the guide post 430 moves in the circumferential direction of the first body 310 in the fourth channel 334 before entering the first channel 331, so that the film cutting member 400 and the bin 300 relatively rotate, and the relative position in the axial direction is unchanged.

By arranging the fourth channel 334, the guide post 430 moves in the circumferential direction of the first body 310 in the fourth channel 334 before entering the first channel 331, so that the film cutting member 400 and the bin 300 relatively rotate, 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 required to be overcome by the second cutter 240 for cutting the isolation plate 540 at first and the larger resistance required to be overcome by the guide post 430 along the first channel 331 and the second channel 332 are dispersed, the maximum driving force required to screw the bottle cap 100 is reduced, and a user can screw the bottle cap 100 conveniently.

The present utility model further provides a bottle 600 according to the second aspect, including the bottle cap 100 according to the second aspect, further including a bottle body 610 having a receiving cavity 620 and a bottle mouth 630 communicating with the receiving cavity 620, wherein the bottle cap 100 seals the bottle mouth 630, and the second cap 500 is rotatably connected to the bottle body 610. By applying the bottle cap 100 of the second aspect of the present utility model, the movement of the film cutting member 400 can be guided by the cooperation of the guide groove 330 and the guide post 430, thereby achieving the film cutting operation of the film cutting member 400 on the sealing film 340. Compared with the prior art in which the screwing-in direction of the bottle cap 100 is utilized, the bottle cap 100 is screwed in along the screw thread first and then screwed out along the screw thread so that the stripping member moves relative to the sealing film 340, a limiting ring is not required to be arranged on the bottle body 610, thus facilitating the stripping and uncapping operations of drinkers and reducing the possibility of environmental pollution caused by the limiting ring. On the basis, the second cover 500 is matched with most of threads of the universal bottle body 610, so that the requirement on the structure of the bottle body 610 when the bottle cover 100 realizes a film cutting function is reduced, and the applicability of the bottle cover 100 is improved.

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