Description

Technical Field

[0001] This utility model relates to a switch-press cosmetic dropper bottle. Background Technology

[0002] Chinese patent CN203467894U discloses a novel cosmetic liquid dispensing dropper, comprising a bottle body, a dispensing dropper, and a connecting assembly between the bottle body and the dispensing dropper. The bottle body contains cosmetic liquid. The dispensing dropper includes a suction section and a dropper section. The bottom end of the dropper section is located at the bottom of the bottle body, and the suction section is located outside the top of the bottle body. A dropper outlet is provided at the top of the bottle body, and the dropper section passes through the dropper outlet. The suction section is a flexible suction tip, and the dropper section is a hollow tube with a tapered bottom. The bottom end of the flexible suction tip is sealed and detachably fixed to the upper part of the dropper section. The suction section is connected to the connecting assembly. Although the dispensing method only requires one finger and is easy to operate, avoiding contamination of the cosmetic liquid in the bottle, there is a problem of accidental pressing to draw liquid, which can cause the flexible suction tip to react and be damaged if the liquid remains inside. Summary of the Invention

[0003] The purpose of this invention is to address the problem of accidental liquid aspiration in existing dropper bottles by providing a switch-operated, push-button cosmetic dropper bottle.

[0004] The purpose of this utility model is achieved as follows: A push-button cosmetic dropper bottle includes a bottle body and a dropper dispensing assembly. The dropper dispensing assembly includes a flexible suction head, a glass straw, an inner cap, an outer cover, and a button. The flexible suction head is fastened to the inside of the inner cap and is sealed to the glass straw, which connects the liquid in the bottle body. The inner cap is tightly fitted to the outer cover through its lower cylindrical part, and the inner cap cooperates with the bottle opening to install the dropper dispensing assembly on the bottle body. The button has a ring-shaped design on its upper side. The outer cover has a shoulder sleeve on its upper side, which blocks the annular shoulder and limits the button when subjected to the upward elastic force of the elastic suction head. The button is fitted into the upper cylindrical part of the inner cover through its cylindrical part. The inner wall of the button's cylindrical part is provided with a protruding rib. The lower end face of the protruding rib slides and engages with the sliding shoulder provided on the upper side of the inner cover, forming a structure in which the button can rotate axially around the inner cover. The inner cover is provided with a slot that can be inserted into the protruding rib. The insertion of the protruding rib into the slot allows the button to compress the elastic suction head downward to draw liquid, thus forming an open liquid drawing structure.

[0005] In this invention, the outer cover has a positioning ridge on its inner wall, which is positioned and installed in accordance with the positioning groove of the lower cylinder of the inner cover. In this way, the positional relationship between the outer cover and the inner cover is stable, ensuring that the dropper liquid dispensing component can be screwed out when a rotational force is applied to the outer cover.

[0006] In this invention, the button is connected to the top of the elastic suction head through a horizontal rib formed inside it. Since the contact area between the horizontal rib and the top of the elastic suction head is relatively small, they are easy to separate, preventing jamming and ensuring that the suction action is unobstructed.

[0007] The positive effects of this utility model are that by providing a protruding ridge on the inner wall of the button's cylindrical part, and the lower end face of the protruding ridge slidingly engaging with the sliding shoulder provided on the inner cover, the button can rotate axially around the inner cover; by providing a slot in the inner cover, the protruding ridge of the button can be inserted into the slot of the inner cover, allowing the button to compress the elastic pipette head downwards to start liquid aspiration; thus, it can prevent accidental liquid aspiration from the dropper bottle and extend the service life of the elastic pipette head.

[0008] The following embodiments, in conjunction with the accompanying drawings, further illustrate the present invention. Attached Figure Description

[0017] Reference Figures 1 to 7This embodiment is a push-button cosmetic dropper bottle, including a bottle body 1 and a dropper dispensing assembly. The dropper dispensing assembly includes a flexible suction head 2, a glass straw 3, an inner cap 4, an outer cover 5, and a button 6. The flexible suction head is fastened to the inside of the inner cap and is sealed to the glass straw, which connects the liquid in the bottle body. The inner cap is tightly fitted onto the outer cover through its lower cylindrical part, and the inner cap fits with the bottle opening to install the dropper dispensing assembly on the bottle body. The button has a ring shoulder 7 on its upper side, and the outer cover has a ring shoulder 7 on its upper side. A shoulder sleeve 8 is provided, which blocks the annular shoulder to limit the button when subjected to the upward elastic force of the elastic suction head; the button is fitted into the upper cylindrical part of the inner cover through its cylindrical part, and a pair of protruding ribs 9 are provided on the inner wall of the button's cylindrical part. The lower end face of the protruding ribs slides and engages with a pair of sliding shoulders 10 provided on the upper side of the inner cover, forming a structure in which the button can rotate axially around the inner cover; the inner cover is provided with a pair of slots 11 that can be inserted into the pair of protruding ribs, and the insertion of the protruding ribs into the slots allows the button to compress the elastic suction head downward to draw liquid, thus forming an open liquid drawing structure.

[0018] In this utility model, the outer cover has a positioning ridge 12 on the inner wall. The positioning ridge is positioned and installed in the positioning groove 13 of the lower cylinder of the inner cover. In this way, the positioning ridge and the positioning groove are combined to ensure that the inner cover and the outer cover no longer have relative rotational movement after they are combined. The positional relationship between the outer cover and the inner cover is stable, ensuring that the dropper liquid dispensing component can be screwed out when a rotational force is applied to the outer cover.

[0019] In this invention, the button is connected to the top of the elastic suction head through the internally formed horizontal rib 14. Since the contact area between the horizontal rib and the top of the elastic suction head is relatively small, they are easy to separate, preventing jamming and ensuring that the liquid aspiration action is unimpeded.

[0020] Reference Figure 2 When using this invention, the lower surface of the button is in elastic contact with the top of the elastic suction head. First, rotate the button. After the button rotates around the inner cover axially, the protrusion of the button is allowed to insert into the slot of the inner cover. The button compresses the elastic suction head downward, so that a negative pressure is formed inside the elastic suction head. Then, after releasing the top button, under the action of the negative pressure, the bottom end of the glass straw begins to draw the cosmetic liquid into the elastic suction head. At the same time, the top button returns to its original shape and pops up under the elastic action of the elastic suction head until the ring shoulder of the button is blocked by the shoulder sleeve of the outer cover and is limited.

[0021] Reference Figure 1 , Figure 2 Rotating the dropper assembly causes the inner cap to rotate relative to the bottle opening, separating the dropper assembly from the upper part of the bottle. Pressing the button dispenses the dispensed cosmetic liquid from the glass straw. After the button resets, rotating it causes the lower end of the raised ridge to slide along the sliding shoulder on the upper side of the inner cap to its stop position, preventing further downward movement of the button. The dropper assembly is now in its optimal position. Figure 3 , Figure 4 The device is in the off state.
