Description

Technical Field

[0001] The invention belongs to the technical field of drinking dairy product containers, and in particular relates to an easy-to-open milk bottle. Background Art

[0002] The Chinese invention patent with authorization announcement number CN 110406794 B discloses an easy-to-twist bottle cap, which solves the technical problem that when the hot air in the bottle shrinks in volume due to the decrease in temperature, a certain degree of negative pressure is formed in the bottle, making it difficult to twist the bottle cap open.

[0003] The technical solution adopted is to set a friction plate and a drivable rotating sleeve on the bottle cap, and twist the disc spring at the same time to store energy. The friction plate is driven to rotate by repeatedly pulling and turning the pull rope. The rapidly rotating friction plate rubs against the heat conductive block, thereby causing the heat conductive block to heat up rapidly and transfer the heat to the air in the bottle, causing the air to expand due to the heat and increase its volume, thereby reducing the pressure difference between the inside and outside of the bottle, and making it easier to twist the bottle cap body.

[0004] Compared with the above technical problems, the temperature of dairy drinks is lower when they are canned, and negative pressure is not easily generated in the bottle. The main factor that makes it difficult to open the bottle cap is the tear strip connected to the bottom edge of the cap that shows that the bottle is unopened. Of course, adults and teenagers with a certain amount of arm strength can easily open it, but for children and the elderly, it is not easy to open it by their own strength alone.

[0005] On the other hand, dairy drinks have been stored for a long time, so it is best to shake them well before drinking (especially when opening them for the first time), but it is generally difficult for children to develop this habit. Summary of the invention

[0006] The present invention aims at solving the above problems and provides an easy-to-open milk bottle. After the safety bolt is pulled out, the bottle body of the milk bottle needs to be shaken a certain number of times before the bottle cap can be opened. At the same time, when the bottle cap can be opened, the bottle cap will automatically obtain torsional stress to help the bottle cap to be opened easily.

[0007] The object of the present invention is achieved by the following technical solutions: An easily openable milk bottle includes a bottle body and a bottle cap that are threadedly connected to each other, and the two are further connected to display a tear strip that has not been unsealed. The milk bottle further includes: a torsion assembly disposed in the bottle body that can form a torsional prestress, and a trigger assembly that releases the torsional stress by shaking the bottle body; the torsion assembly includes an actuating gear ring rotatably connected to the neck of the bottle body and a trigger for positioning the actuating gear ring. The circumferential surface of the actuating gear ring has a locking hole, and the front section of the trigger has a protrusion that can enter the locking hole. The middle section of the trigger is hinged to the bottle body, and a trigger torsion spring is installed at the hinge. The rear section of the trigger is a pressing portion; by continuously shaking the bottle body, the trigger assembly applies a force to the pressing portion. After being stressed, the pressing portion transmits to the protrusion to make it lift off the locking hole, thereby enabling the torsion assembly to release the torsion force, and this torsion force becomes the rotational force to assist in opening the bottle cap.

[0008] Preferably, the upper half of the bottle body is provided with an installation area for arranging the trigger assembly. The installation area is set as small as possible in the upper half of the bottle body to minimize the impact on its internal accommodation space.

[0009] Preferably, the two sides of the bottle body are planes and the rest is a circular rotating body. The installation area is recessed in the upper half of one of the planes. The design with two sides being planes makes the space utilization rate higher when packing compared to a cylindrical shape, and the bottles can be packed more stably with plane-to-plane contact with each other.

[0010] Preferably, the installation area is snap-connected with a cover. The cover protects the internal parts and also keeps parallel to the initial plane on the outside.

[0011] Preferably, the trigger assembly includes a sliding block with an upper end pressing against the pressing portion and a lower end being a free end. Below the sliding block, there is a cam that can form a rotational prestress and is rotatably installed on the installation area. A fixed slide seat is fixed on the installation area to install the sliding block.

[0012] Preferably, a notch is provided on the circumferential surface of the cam. The milk bottle is also provided with a shaking unlocking assembly for locking and unlocking the cam. The shaking unlocking assembly includes a stop pin that abuts against the notch, a spherical body bin fixed to the installation area for slidably installing the stop pin, a plurality of solid balls installed in the spherical body bin, a spherical body storage bin below the spherical body bin, a toggle gate that is hinged in the middle to the lower edge of the outer side wall of the spherical body bin, with one end abutting against the bottom surface of the lower opening of the spherical body bin to form a closure and the other end extending away from the spherical body bin; the extended end of the toggle gate is fixedly connected with a magnetic attraction block. The shaking unlocking assembly further includes a guiding channel fixedly installed on the installation area and closely arranged below the magnetic attraction block, and a solid sphere movably placed in the guiding channel.

[0013] Preferably, a notch is provided on the outer side of the guiding channel, and a movable plug-in blocking safety bolt is arranged between the notch and the upper surface of the toggle gate. An easy tear mark is provided at the position corresponding to the cover of the blocking safety bolt, and the tearing part of the blocking safety bolt is exposed at the edge of the side plane.

[0014] Preferably, the gear ring of the actuating gear ring is located on its upper surface. Correspondingly, the lower surface of the bottle cap has a matching gear ring. A prestressed torsion spring is arranged inside the actuating gear ring, one end of which is fixedly connected to the bottle body, and the other end of the torsion spring is fixed inside the actuating gear ring.

[0015] Preferably, the cam is provided with a disc spring and a fixed shaft on the back to complete the stress setting for the rotation of the cam.

[0016] Preferably, the working surface of the sliding block is set as an inclined plane, and the working surface of the pressing part is also set to be inclined downward at a certain angle.

[0017] In summary, compared with the prior art, the present invention has the following advantages:

[0018] The overall shape and internal structure of the original milk bottle are changed little in the present invention. It ingeniously uses shaking to unlock the first opening, which is extremely convenient to use. That is, it must be shaken first to open the bottle for the first time, thus solving the technical problem mentioned in the background art that it is difficult for children to have this habit before drinking. And the installation position of the prestressed torsion spring has sufficient space to adjust its size, so it is convenient to find a suitable specification to counteract the connection force of the easy tear tape, thereby achieving the purpose of assisting children and the elderly to easily open the bottle cap. Of course, if the milk cannot be finished at one time and the bottle cap needs to be tightened and opened repeatedly, after the adult tightens the bottle cap, children and the elderly can still obtain the auxiliary force to unscrew the bottle cap by pressing the switch.

[0019] In summary, after improving the existing defects, the present invention has little impact on the overall structure, the processing cost increases little, and multiple functional components interact and integrate with each other in the structure, with few components and convenient use.

Specific implementation mode

[0026] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings:

[0027] Embodiment 1

[0028] As Figure 1-2 shown, an easily openable milk bottle includes a bottle body 1 and a bottle cap 2 that are threadedly connected to each other. The two are further connected to show the unsealed tear strip 01. A torsion assembly 3 that can form a torsional prestress and a trigger assembly 4 that releases the torsional stress by shaking the bottle body 1 are arranged in the bottle body 1. The two sides of the bottle body 1 are planes and the rest is a rotary body with a circular shape. The upper half of one of the planes is provided with a concave installation area 11 for arranging the trigger assembly 4. The installation area 11 is buckled with a cap 12 so that the large surface is aligned with the side plane.

[0029] The torsion assembly 3 includes an actuating gear ring 31 that is rotatably connected to the neck of the bottle body 1 and a trigger 32 for positioning the actuating gear ring 31. The circumferential surface of the actuating gear ring 31 has a locking hole 311. The front section of the trigger 32 has a protrusion 321 that can enter the locking hole 311. The middle section of the trigger 32 is hinged to the bottle body 1, and a trigger torsion spring is installed at the hinge. The torsion of the torsion spring makes the protrusion 321 move towards the locking hole 311 under normal conditions. The rear section of the trigger 32 is a pressing part 322. The trigger assembly 4 includes a sliding block 41 with one end pressing upward on the pressing part 322 and the other end being a free end. Below the sliding block 41, a cam 42 that can form a rotational prestress and is rotatably installed on the installation area 11. The sliding block 41 is restricted to only slide up and down by a fixed sliding seat fixed on the installation area 11. During the rotation of the cam 42 after the stress is released, the outer circumferential surface of the cam abuts against the free end of the sliding block 41, so that the sliding block 41 moves upward and further presses the rear section of the trigger 32 until the protrusion 321 disengages from the locking hole 311. At this time, the torsional prestress of the torsion assembly 3 is released, that is, the actuating gear ring 31 rotates by a certain amplitude, and this rotation will cause the tearable part of the tear strip 01 to rupture or be close to rupture, thereby helping the person opening the cap to open the bottle cap without much effort.

[0030] In order to control the release of stress from the cam 42 only when needed, the milk bottle is also provided with a shaking unlocking assembly 5 for locking and unlocking the cam 42. For this purpose, a notch 421 is formed on the circumferential surface of the cam 42. The shaking unlocking assembly 5 includes a stop pin 51 that abuts against the notch 421, a sphere bin 52 fixed in the installation area 11 for slidably mounting the stop pin 51, a plurality of solid spheres 521 installed in the sphere bin 52, a sphere storage bin 53 below the sphere bin 52, a seesaw gate 54 that is hinged in the middle to the lower edge of the outer sidewall of the sphere bin 52, with one end abutting against the bottom surface of the lower opening of the sphere bin 52 to form a closure and the other end extending away from the sphere bin 52; a magnetic attraction block 541 is fixedly connected to the extended end of the seesaw gate 54. The shaking unlocking assembly 5 further includes a guiding channel 55 fixedly installed in the installation area 11 and closely arranged below the magnetic attraction block 541, and a solid sphere 56 movably placed in the guiding channel 55; for the hinge position between the seesaw gate 54 and the sphere bin 52, see Figure 4 , the hinge position has a limiting effect on the position of the seesaw gate 54, that is, the opening size of the seesaw gate 54 can be blocked and restricted.

[0031] To ensure the stability of the solid sphere 56 and the seesaw gate 54 in the normal state, a notch is provided on the outer side of the guiding channel 55, and a movable plug-in blocking safety bolt 6 is arranged between the notch and the upper surface of the seesaw gate 54. At the position of the cover 12 corresponding to the blocking safety bolt 6, an easy tear mark 122 is provided. In this way, when the blocking safety bolt 6 is inserted, it just fixes the solid sphere 56 and the seesaw gate 54 simultaneously, and the tearing part of the blocking safety bolt 6 is exposed at the side plane edge.

[0032] For the milk bottle of the present invention, the first opening must be achieved by shaking the bottle body, while subsequent openings do not require this. The purpose of this design is that milk or milk containing fruit ingredients is prone to precipitation after long-term standing. Therefore, it is set that the first opening requires shaking the bottle body to unlock the trigger 32 first. For the second opening, a push switch 121 is provided at the position of the cover 12 corresponding to the pressing part 322, and the trigger 32 can be unlocked by directly pressing the push switch 121. This is because when opening for the first time, the lower part of the sliding block 41 falls on the circumferential surface of the cam 42, and a small part of the upper part of the sliding block 41 is above the pressing part 322. In this way, the position of the sliding block 41 is limited. When the push switch 121 is pressed down, it first touches the upper surface of the pressing part 322. Therefore, the push switch 121 cannot press down the pressing part 322 to unlock the trigger 32. When the second opening is required, after the cam 42 rotates, the movable range between the sliding block 41 and the cam 42 increases. At this time, when the push switch 121 is pressed, it will not touch the sliding block 41. Or even if it touches the sliding block 41, after the movable range increases, the sliding block 41 can move downward, so as not to block the push switch 121.

[0033] From Figure 3As can be seen, the gear ring of the actuating gear ring 31 is located on its upper surface. Correspondingly, the lower surface of the bottle cap 2 has a matching gear ring. One end of the prestressed torsion spring 02 arranged inside the actuating gear ring 31 is fixedly connected to the bottle body. It can be seen from the figure that the position of the bottle body at this location has reinforcement treatment. The other end of the torsion spring is fixed inside the actuating gear ring 31, and reinforcement treatment is also required here (not shown in the figure). When the bottle cap 2 is fully closed, the gear ring parts of the actuating gear ring 31 and the lower surface of the bottle cap 2 are fully engaged, and the torsion spring is compressed to generate torsional stress. The locking hole 311 of the actuating gear ring 31 is positioned by the protrusion 321. It can also be seen from the figure that there is a certain space for the position of the torsion spring, which is sufficient to allow it to select an appropriate diameter to obtain an appropriate torque. The cam 42 completes the stress setting for the rotation of the cam by arranging a disc spring and a fixed shaft on the back. The prestressed torsion spring 02 can also be other components with torsional performance, such as a disc spring.

[0034] The positional relationship and working state of the above components after installation: The lower end of the stop pin 51 lands on the solid ball 521, and the upper end of the stop pin 51 abuts against the notch 421, whereby the cam 42 is positioned. The guide channel 55 is made of a magnetizable metal material. The solid sphere 56 impacts the magnetic attraction block 541 through external up and down shaking in the guide channel 55. After being impacted, the magnetic attraction block 541 moves upward and then resets under the action of magnetic force. Repeatedly like this, the section of the toggle gate 54 sealing the lower opening of the sphere bin 52 continuously opens and closes. When it opens, the solid ball 521 slides into the sphere storage bin 53. Repeatedly like this, the number of solid balls 521 in the sphere bin 52 becomes less and less, and the support height of the stop pin 51 immediately drops until the limit on the cam 42 is completely released. When opening the bottle cap for the first time, apply force to the blocking safety bolt 6 towards the tear mark 122 side and pull it out, then shake the bottle body 1 up and down. As described above, the solid sphere 56 causes the stop pin 51 to move away from the cam 42 with the shaking. The cam 42 pushes the sliding block 41 to move upward. The sliding block 41 presses the pressing part 322, causing the trigger 32 to unlock the actuating gear ring 31. The actuating gear ring 31 rotates under the torsional force of the torsion spring, driving the bottle cap 2 to rotate synchronously. The rotation of the bottle cap 2 is an upward movement to loosen, while the actuating gear ring 31 cannot move upward. Therefore, the tear strip 01 between the two is in a torn or about-to-be-torn state. At this time, it will be extremely easy to rotate the bottle cap synchronously by hand.

[0035] It should be noted that in order to make the sliding block 41 more easily press the pressing part 322, the contacting surface of the sliding block 41 is set as an inclined surface, and the pressing part 322 is also set to be inclined downward at a certain angle; in order to lock the bottle cap 2 when closing the bottle cap, strengthening parts are respectively arranged on both sides of the locking hole 311, and arc transition treatment is performed on this part, so that the protrusion 321 can smoothly enter the locking hole 311, thereby locking the bottle cap 2. To open it again, just press the push button switch 121 as described above.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
