[0044] A tooth cap 2, the tooth cap 2 is detachably connected to the opening of the bottle body 1, and a connection port 21 is arranged at the upper end of the tooth cap 2;

[0045] A soft rubber head 3, the middle part of the soft rubber head 3 is clamped in the connection port 21, the upper part of the soft rubber head 3 protrudes out of the tooth cap 2, the lower part of the soft rubber head 3 is located inside the tooth cap 2 and at the same time inside the opening of the bottle body 1, and an elastic connection part 4 is arranged at the lower part of the soft rubber head 3; and

[0046] A dropper part 6, the upper part of the dropper part 6 is connected to the elastic connection part 4, the lower end of the dropper part 6 extends into the bottle body 1. In the closed state, the lower end of the dropper part 6 contacts the bottom of the bottle body 1, and the elastic connection part 4 is in a compressed state.

[0047] Further, it further includes an inner plug 5. The outer side wall of the inner plug 5 is connected to the inner side of the opening of the bottle body 1. An inward inner convex platform 51 is arranged on the inner side wall of the inner plug 5. The inner convex platform 51 is arranged in a ring shape and contracts inward from top to bottom, and at the same time contacts the outer wall of the dropper part 6. Generally, it is arranged in an interference fit, which can realize the scraping of the outer wall of the dropper part 6 and avoid waste of the material.

[0048] Further, the outer side wall of the inner plug 5 and the inner side of the opening of the bottle body 1 are connected by a snap connection. That is, the cooperation of the protrusion and the groove can make the connection between the two more stable.

[0049] Further, a positioning protrusion 52 is also arranged on the upper part of the inner plug 5, and the positioning protrusion 52 contacts the upper end surface of the bottle body 1. It can ensure the replacement effect of the inner plug 5. When the inner plug 5 is damaged, the replacement is realized through the positioning protrusion 52.

[0050] Further, the elastic connecting portion 4 is made of rubber or silica gel. By choosing the material, automatic resilience can be achieved. At the same time, it can be set in a corrugated shape to better achieve resilience. Even a spring can be sleeved to assist in resilience. In this product, it is recommended to use a corrugated rubber material, which has a simple and reliable structure.

[0051] Further, the connection mode between the tooth cap 2 and the outer side of the opening of the bottle body 1 is any one of screw thread, magnetic attraction or snap connection. Screw thread connection is a relatively common way and is also the recommended way in this structure.

[0052] Further, a shoulder sleeve 7 is also arranged on the outer side of the tooth cap 2.

[0057] Further, the first snap 31 is located above the second snap 32, and the outer side of the first snap 31 is inclined. The smooth connection between the second snap 32 and the tooth cap 2 is ensured through the inclined slope.

[0058] Further, the second snap 32 extends outwards and contacts the upper end of the opening of the bottle body 1. The stable installation of the soft rubber head 3 is ensured.

[0059] Further, a diversion channel is arranged on the lower end surface of the dropper portion, and the diversion channel is composed of a diversion protrusion or a diversion groove. Through the setting of the diversion channel, the smooth inhalation of the material into the dropper can be ensured. When the diversion protrusion is set, see Figure 9 as shown; when the diversion groove is set, it is generally arranged radially to ensure that the material flows into the dropper portion from the outside, and at least one diversion groove is set. For details, see Figure 10 .

[0060] Compared with traditional dropper bottle packaging materials, this product has an added self-suction device. Through the automatic rebound of the elastic connecting part 4, when consumers use it, the dropper automatically sucks the material, and it can be used as soon as it is opened without manual material extraction. The entire self-suction structure can be achieved with only one soft rubber, and the rebound stroke of the soft rubber can be adjusted according to different materials to control the single dosage. The structure is simple and the design is novel, and it can be applied to various materials. Due to the need to reserve a safety gap between the dropper and the bottom of the bottle, most dropper bottles on the market currently have a large problem of residual amount. The added self-suction device of this product is made of soft material, there is no need to leave a gap between the dropper and the bottom of the bottle, there is no residue during use, waste is reduced, and it is more environmentally friendly.

[0061] Basic assembly steps:

[0062] The soft rubber head and the elastic connecting part are integrally set (usually integrally injection molded);

[0063] First, assemble the soft rubber head into the tooth cap from bottom to top, and the first buckle and the second buckle are snap-connected;

[0064] Assemble the dropper part from bottom to top, and after snap-connection, the first protrusion abuts against the lower end of the elastic connecting part;

[0065] The button is assembled into the shoulder sleeve from bottom to top; the tooth cap assembly is assembled into the shoulder sleeve from bottom to top, and at the same time, the top of the soft rubber head is in interference fit with the inner side of the button to complete the assembly of the entire dropper head (this step is omitted when there is no shoulder sleeve and button);

[0066] Assemble the inner plug (the inner plug is made of plastic material) into the bottle body from top to bottom. The inner convex platform of the inner plug is snap-connected to the side wall of the dropper part, and the positioning protrusion abuts against the bottle mouth to complete the assembly.

[0067] Finally, the tooth cap is screwed into the bottle body clockwise. At this time, the dropper part is inserted into the bottle along the inner plug, and the inner convex platform part of the inner plug abuts against the outer wall of the dropper part. When the dropper part is pulled out, it scrapes the material on the outer wall. When the dropper is not pulled out, it can stabilize the dropper part and prevent the dropper part from shaking.

[0068] When in use, unscrew the bottle cap combination counterclockwise. When gradually rising, the elastic connecting part rebounds and automatically sucks the material. Press the button or squeeze the top of the soft rubber head to use it. After use, screw it in clockwise.

[0069] The bottom of the dropper part contacts the bottom of the bottle body, and the elastic connecting part is compressed. According to different materials, dropper parts of different lengths can be selected to achieve different degrees of compression of the elastic connecting part. That is, the rebound stroke of the elastic connecting part can be adjusted according to different materials to control the single dosage and reduce material waste. During the whole process, the inner plug scrapes off the excess material on the outer wall of the dropper part, which is also the key to avoiding material waste.

[0070] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
