See Figure 1-16, a storage bottle cap comprising:

The outer cover 100 is provided with an extension sleeve 110;

The inner cover 200 is arranged under the outer cover 100, the inner cover 200 is provided with a silo 210 and a connecting through hole 230, the hopper 210 is arranged at the bottom of the inner cover 200, and the connecting through hole 230 runs through the The inner cover 200;

The silo cover 300 is arranged at the bottom of the silo 210, the silo cover 300 is provided with a connecting rod 310, and the connecting rod 310 extends into the outer cover 100 through the connecting through hole 230;

The first locking mechanism is arranged between the connecting rod 310 and the extension sleeve 110, and is used to connect the connecting rod 310 and the extension sleeve 110, so as to prevent the bin cover 300 from detaching from the outer cover 100;

Wherein, the silo cover 300 is opened by driving the connecting rod 310 in the extension sleeve 110 to move down.

In this embodiment, by setting the first locking mechanism, when the connecting rod 310 is driven to move down to open the bin 210, the bin cap 300 will not break away from the outer cap 100, preventing the bin cap 300 from falling into the bottle, which is safe. The coefficient is higher.

Wherein, the inner cap 200 is provided with an internal thread for being installed on the bottle.

In one embodiment, the connecting rod 310 is a tubular body with a cavity, the extension sleeve 110 is a rod body, the connecting rod 310 is sleeved on the extension sleeve 110, and the connecting rod 310 It is connected with the extension sleeve 110 through a first locking mechanism.

This embodiment is a variation of the embodiment in which the connecting rod 310 is extended to the extension sleeve 110 hereinafter, and those skilled in the art can derive the specific implementation principle from the following without creative thinking.

Please refer to Figures 1-8, 12. In one embodiment, the connecting rod 310 extends into the extension sleeve 110 through the connecting through hole 230, and the first locking mechanism includes a The first limiting member 311 on 310 and the second limiting member 111 arranged on the extension sleeve 110 can be rotated by rotating the first limiting member 311 relative to the second limiting member 111 and/or Move vertically to open the bin 210.

In this embodiment, there are three implementation situations, all of which are implemented without increasing the height of the bottle cap. The user experience is better, and it is easy to carry. It is suitable for standard machines such as existing vending machines. Carry out adaptive improvement and put it into market use faster.

In the first implementation situation (in the case that the bin cover 300 will move down by itself due to the extrusion of material gravity), the first stopper 311 can be rotated relative to the second stopper 111 to open the silo 210; the specific embodiment is that the second limiter 111 is an inverted L-shaped through hole on the side wall of the extension sleeve 110, and under normal circumstances, the first limiter 311 is arranged on the second limiter. In the positioning part 111, the first limiting part 311 and the second limiting part 111 cooperate to limit the downward movement of the silo cover 300. After the outer cover 100 is rotated at a certain angle, the first limiting part 311 will be opposite to the second limiting part 111. Move to the right-angle turn of the through hole, and then under the action of gravity, the bin cover 300 moves down. At this time, the bin cover 300 is opened, and the material in the bin 210 enters the bottle and mixes with the liquid in the bottle. Pay attention The most important thing is that the inverted L-shaped second stopper does not extend to the bottom of the extension sleeve, so the downward moving silo cover will not fall into the bottle.

In the second implementation situation (under the condition that the silo cover 300 will not automatically move down due to being squeezed by the gravity of the material), the first stopper 311 can be vertically moved relative to the second stopper 111 . to move to open the bin 210; the specific embodiment is that the second limiting member 111 is a concave or through hole on the side wall of the extension sleeve 110, the first limiting member 311 is a protrusion, and the first limiting member 311 is a protrusion. The positioning member 311 is located above the second limiting member 111, and the first limiting member 311 and the second limiting member 111 are located on the same vertical plane. When the material bin 210 needs to be opened, the outer cover 100 is lifted so that the first limiting member Part 311 snaps into the second limiting part 111, and presses down the outer cover 100, drives the connecting rod 310 to move down by external force, and opens the feed bin 210.

Specifically, in order to achieve the situation that the bin cover 300 will not automatically move down due to the extrusion of the gravity of the material, the material may be lighter, and the connecting through hole 230 may be provided with an additional connecting rod 310 and a connecting through hole 230. The first friction component (such as a rubber ring, which is tightly connected between the rubber ring and the connecting through hole 230), or the extension sleeve 110 is provided with an increase between the first stopper 311 and the extension sleeve 110. Between the friction force of the second friction component, and so on.

In the third implementation situation, the bin 210 can be opened by the first limiting member 311 rotating relative to the second limiting member 111 and moving vertically.

The third implementation situation includes the first implementation situation.

The difference between the third implementation and the second implementation is only that the first limiting member 311 and the second limiting member 111 are located in different vertical planes, so it needs to be rotated so that the first limiting member 311 and the second limiting member 311 are located in different vertical planes. The limiter 111 is located in the same vertical plane, and the next operation is the same as the second case.

In one embodiment, the second limiting member 111 is arranged below the first limiting member 311, and by pushing the connecting rod 310 where the first limiting member 311 is located, the connecting rod 310 moves down, so that the first limiting member 311 moves downward. A limiting member 311 and the second limiting member 111 are engaged to restrict the connecting rod 310 from detaching from the outer cover 100 , so as to prevent the bin cover 300 from falling off.

In this embodiment, it is specifically the above-mentioned second implementation situation, the "moving down by pushing the connecting rod 310 where the first limiting member 311 is located" can be understood as directly pushing the connecting rod 310 down, or It is understood that after the outer cover 100 is lifted so that the first stopper 311 and the second stopper 111 are engaged and connected, the outer cover 100 is pressed down, and the connecting rod 310 moves down at this time.

Please refer to Fig. 1-8, in one embodiment, the included angle between the second limiting member 111 and the first limiting member 311 on the horizontal plane is a first angle, by rotating and pushing the first limiting member The connecting rod 310 where the positioning member 311 is located moves down, so that the first limiting member 311 and the second limiting member 111 are snapped together to restrict the connecting rod 310 from detaching from the outer cover 100 to limit The bin cover 300 falls off.

In this embodiment, it is specifically the above-mentioned third implementation situation.

Please refer to FIG. 12 , in one embodiment, the first limiting member 311 includes two elastic members facing oppositely, a first protrusion is provided on the outside of the elastic members, and the two elastic members respectively have The elastic force on the outside and abuts against the inner wall of the extension sleeve 110, the second limiting member 111 includes a first through hole oppositely arranged on the side wall of the extension sleeve 110, and the first protrusion The connecting rod 310 is restricted from detaching from the outer cover 100 by snapping into the first through hole.

In this embodiment, the elastic force of the elastic member enables the first protrusion to be completely locked into the first through hole.

Specifically, it is also possible for the first limiting member to include more than two elastic members, a plurality of elastic members in an equiangular circular array, and correspondingly, the second limiting member is provided with a plurality of first through holes corresponding to the first limiting member , which can be modified according to the actual situation.

Please refer to Fig. 15-16, in one embodiment, a second locking mechanism is provided between the connecting rod 310 and the extension sleeve 110, and the second locking mechanism is used for unlocking when the first locking mechanism is not locked. When connecting the connecting rod and the extending sleeve, the vertical movement of the connecting rod 310 relative to the extending sleeve 110 is restricted, so as to prevent the silo cover 300 from moving down and opening by itself.

In this embodiment, since the above-mentioned situation in which the hopper cover 300 will not automatically move down due to gravity is not reliable, over time, problems such as rubber aging are prone to occur, so by connecting the connecting rod 310 and the extension sleeve A second locking mechanism is arranged between the tubes 110. When the material in the bottle cap is not used, the vertical movement of the connecting rod 310 relative to the extension sleeve 110 is restricted by the second locking mechanism, so that the silo cover 300 will not be opened to avoid Due to the above-mentioned problems such as rubber aging, the hopper cover 300 is opened in advance, which affects the use.

In a preferred embodiment, the second locking mechanism includes a third limiting member 312 arranged on the connecting rod 310 and a fourth limiting member 112 arranged on the extension sleeve 110, the third The limiter 312 is disposed in the fourth limiter 112 , and the bin 210 is opened by rotating the third limiter 312 relative to the fourth limiter 112 and moving down.

In this embodiment, the second locking mechanism should not only restrict the vertical movement of the connecting rod 310 relative to the extension sleeve 110 under normal conditions (the silo is not opened), but also have the ability to connect when in use (the silo can be opened). The rod 310 can move vertically relative to the extension sleeve 110 to open the feed bin 210; therefore, by setting the third limiter 312 and the fourth limiter 112, the third limiter 312 is normally stuck in the fourth limiter. In the positioning part 112, the vertical movement of the connecting rod 310 relative to the extension sleeve 110 can be restricted. When it is required to use, the outer cover 100 is rotated so that the third limiting part 312 rotates relative to the fourth limiting part 112 to the fourth limiting part. 112, so as to push the connecting rod 310 down (here, pushing the connecting rod 310 down can be understood as directly pushing the connecting rod 310 down, and can also be understood as lifting the outer cover 100 to make the first stop After the member 311 is engaged and connected with the second limiting member 111, the outer cover 100 is pressed down, and the connecting rod 310 moves down at this time).

Specifically, the maximum rotation angle of the third limiting member 312 relative to the fourth limiting member 112 needs to be greater than or equal to the first angle, and the rotation direction is the same as that from the first limiting member 311 to the second limiting member 111 The direction of rotation is the same (the direction of rotation is based on the arc of the smaller angle formed by the two, and the full text is similar).

Please refer to Fig. 2-8, in one embodiment, the third limiting member 312 is arranged under the first limiting member 311, and the fourth limiting member 112 is arranged under the second limiting member 111 below, the vertical distance from the fourth limiter 112 to the second limiter 111 is smaller than the vertical distance from the first limiter 311 to the third limiter 312, and the third limiter 312 is opposite to The maximum rotation angle of the fourth limiting member 112 is the first angle.

In this embodiment, by setting "the vertical distance from the fourth limiter 112 to the second limiter 111 is smaller than the vertical distance from the first limiter 311 to the third limiter 312", the first limiter If the position member 311 wants to be stuck into the second limiter 111, the outer cover 100 needs to be lifted up, and then the outer cover 100 is pressed down to open the feed bin 210, so as to increase the connecting rod 310 to move down the thread, wherein the fourth limiter The difference between the vertical distance from the positioning member 112 to the second limiting member 111 and the vertical distance from the first limiting member 311 to the third limiting member 312 is the length that the connecting rod 310 can move down.

By setting "the maximum rotation angle of the third limiting member 312 relative to the fourth limiting member 112 is the first angle", so that the third limiting member 312 rotates first relative to the fourth limiting member 112 Angle, the first limiter 311 and the second limiter 111 are just in the same vertical plane, so that when the connecting rod 310 is pushed down, the first limiter 311 can just snap into the second limiter 111 , easy to operate.

Specifically, in another embodiment, the only difference from the previous embodiment is that the third limiting member 312 is arranged above the first limiting member 311 , and the fourth limiting member 112 is arranged above the second limiting member 111 , the first stopper 311 is located above the second stopper 111, when the third stopper 312 is rotated by a first angle relative to the fourth stopper 112, after the outer cover 100 is lifted up, the first stopper 311 is snapped into the second limiter 111, and the outer cover 100 is pressed down to open the feed bin 210, and corresponding functions can also be realized, so the first limiter 311, the second limiter 111, the third limiter 312 and The combined relationship between the fourth limiting members 112 is not fixed, and can be changed according to the actual situation.

In one embodiment, the third limiting member 312 includes two second protrusions oppositely disposed, and the fourth limiting member 112 includes two second protrusions oppositely disposed on the extension sleeve. The second through hole on the tube 110.

In this embodiment, by setting the extension sleeve 110 in an oval shape, the second through hole is arranged on the extension sleeve 110 and extends along the extension sleeve 110. As the second through hole moves from one end of the short axis to the long axis When one end is extended, the straight-line distance passing through the center of the ellipse between the two second through holes is constantly increasing. Therefore, when setting the second protrusion, set the second protrusion so that it can just snap into the second through hole and lie on the ellipse. At one end of the short shaft, after the second protrusion rotates by a first angle, the second protrusion breaks away from the second through hole so that the extension sleeve 110 can move vertically relative to the connecting rod 310, so as to facilitate the lifting of the outer cover 100 to pass through the first The locking mechanism fixedly connects the connecting rod 310 and the extension sleeve 110 .

In another embodiment about "the third limiting member 312 rotates and moves down relative to the fourth limiting member 112", the extension sleeve 110 is circular, and the two second through holes are respectively along the The first angle extends clockwise or counterclockwise, and one end of the second through hole extends downward to form an inverted L shape.

In this embodiment, by setting the extension sleeve 110 in a circular shape, and the two second through holes respectively extend the first angle in the clockwise or counterclockwise direction, the extension direction of the second through holes One end extends downward to form an inverted L shape. After the second protrusion extends to the extending direction of the second through hole at a first angle, the second protrusion will be located at the corner extending downward in the second through hole. At this time, the first The stopper 311 is in the same vertical plane as the extension starting end of the second through hole (here the relative position of the first stopper 311 and the first through hole can be other situations, as long as it can make after the outer cover 100 is lifted, The first stopper 311 can be snapped into the first through hole), at this time, the outer cover 100 is lifted, the second protrusion moves down along the second through hole extending downward, and the connecting rod is locked by the first locking mechanism. 310 is fixedly connected with the extension sleeve 110, and at this time, the outer cover 100 is pressed down to open the feed bin 210.
