Description

Technical Field

[0001] This invention relates to droppers, specifically a snap-on dropper bottle. Background Technology

[0002] A dropper is a device that uses a dropper head to dispense temporarily stored liquid from a bottle in a dripping manner. These droppers typically have a separate dropper tube inserted into the bottle opening. Liquid is drawn in or expelled through the dropper tube by pressing the rubber tip. Examples include Chinese patent application number 202111216212.X, published on January 13, 2023, entitled "Residue-Free Dropper Container"; and Chinese patent application number 202223319199.3, authorized on April 18, 2023, entitled "Single Material Dropper Pump Head". However, the aforementioned products use a straw to fix the rubber tip and extend it out of the large ring, making the rubber tip, straw, and large ring a single unit. They rarely use a structural design where the rubber tip and straw are connected as one unit and then the rubber tip is directly snapped to the large ring. In particular, existing similar products generally use screws to tighten and open and close the dropper bottle, and rarely use an inner and outer ring structure design at the bottom of the large ring. The dropper bottle is closed by the outer ring abutting against the shoulder of the bottle mouth below, and the dropper bottle is opened by interference fit separation. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a snap-fit ​​dropper bottle that addresses the technical problem of existing similar products rarely employing an inner and outer ring structure design with a large inner ring at the bottom, and achieving a snap-fit ​​closure by the outer ring abutting against the shoulder of the bottle mouth below, and an opening mechanism by interference fit separation. This objective is achieved through the following technical solution.

[0004] A snap-fit ​​dropper bottle is disclosed, wherein one end of the rubber dropper head is snap-fitted and fixed to the center hole of a large ring. A dropper column is located at the air chamber of the rubber dropper head within the large ring. A rubber tip at the air storage chamber near the other end of the dropper head extends out from the top of the large ring. The liquid inlet at the end of the dropper column extends into the bottle body through the bottle opening. The key structural design feature is that the large ring is a snap-fit ​​ring. The bottom of the snap-fit ​​ring has an inner diameter ring at a height lower than the outer diameter ring. The bottle opening has a protruding, inverted ring-shaped bottle opening fastener on its outer diameter. The bottle opening fastener corresponds to a protruding large ring fastener on the inner wall of the snap-fit ​​ring's inner diameter ring. When the large ring fastener of the snap-fit ​​ring engages with the bottle opening fastener to close the bottle opening, the outer diameter ring of the snap-fit ​​ring abuts against the shoulder below the bottle opening and deforms outwards. The opening and closing of the dropper bottle is achieved by the interlocking and separation of the bottle mouth fastener and the large ring fastener. That is, the above structure is a design that uses the squeezing and locking of the side wall of the large ring to make the dropper detach from the bottle body, so as to achieve the engagement or disengagement of the large ring fastener from the bottle mouth fastener.

[0005] The bottle body is either blow-molded or injection-molded, and the bottom opening of the injection-molded bottle body is fastened and sealed to the injection-molded bottom cap.

[0006] The bottom of the injection-molded bottle and the injection-molded bottom cap are connected at a sealing joint with a multi-stage reflux structure via at least two interlocking grooves. This multi-stage reflux structure significantly improves the sealing effect of the bottle.

[0007] The dropper column has two symmetrically arranged side through holes on the arc surface of the hemispherical head above the central through hole at the end of the liquid inlet head. The side through holes are rectangular.

[0008] The shoulder of the bottle body is provided with a protruding limiting ring; when the large ring of the buckle is engaged with the bottle mouth buckle to close the bottle mouth, the outer diameter of the large ring abuts against the shoulder below the bottle mouth and deforms outward, while the opening at the outer diameter of the large ring abuts against and is limited by the limiting ring.

[0009] The inner shoulder of the limiting ring on the bottle body is provided with an annular groove, and a sealing ring is embedded in the annular groove. When the large ring of the buckle is engaged with the bottle mouth buckle to close the bottle mouth, the outer diameter of the large ring and the lower shoulder of the bottle mouth slide into the annular groove and abut against the sealing ring inside the annular groove, causing outward deformation. Thus, when the large ring of the buckle is engaged with the bottle mouth buckle to close the bottle mouth, the outer diameter of the large ring slides into the annular groove until it abuts against the sealing ring.

[0010] The bottom of the annular groove on the shoulder is provided with equidistant, ring-shaped toothed rings. When the large ring of the buckle is engaged with the bottle mouth buckle to close the bottle mouth, the outer diameter of the large ring and the shoulder below the bottle mouth slide into the annular groove and abut against the toothed rings in the annular groove until they are locked and stopped.

[0011] The rubber dropper head at the top of the buckle ring is provided with an outer cover. The opening of the outer cover fits into or is threaded to the protruding boss at the top of the buckle ring. The rubber dropper head is located in the anti-pressure cavity of the outer cover.

[0012] The outer cover includes a lower cover shell, an upper cover shell, and an inner plug sleeve. The rubber dropper head is fitted into the anti-pressure cavity of the inner plug sleeve. One end of the inner plug sleeve is interference-fitted past the limiting rib located on the inner diameter of the bottom of the lower cover shell. The other end of the inner plug sleeve extends out of the center hole at the top of the lower cover shell and is fastened to the upper cover shell. The top opening of the upper cover shell abuts against the bottom opening of the lower cover shell for limiting. The lower cover shell and the upper cover shell are connected by the inner plug sleeve to form an integral outer shell.

[0013] The inner sleeve has a partition that abuts against the top of the rubber dropper head. Above the central vent of the partition, there is a secondary cavity in the inner sleeve. Below the point where the inner sleeve fits with the rubber dropper head, there is a lower cavity that accommodates the longitudinal deformation of the rubber dropper head and expands outward. After opening the upper cover, pressing the top of the inner sleeve keeps the inner sleeve and the rubber dropper head in place, while the inner sleeve causes the rubber dropper head to deform.

[0014] The present invention has a reasonable structural design, is easy to open and close, has good sealing performance, and has various structural forms. In particular, it adds an outer cap to prevent accidental pressing of the rubber dropper head and an inner stopper sleeve to facilitate pressing operation. It is suitable for use as a snap-on dropper bottle and is a structural improvement of similar products. Attached Figure Description

[0027] The structure of the present invention will now be further described with reference to the accompanying drawings. For example... Figures 1-8 As shown, the rubber dropper head 1 of the dropper bottle is fixedly mounted on the outer diameter of the outer diameter of the dropper head at the center hole of the large ring. The air chamber of the rubber dropper head inside the large ring is provided with a dropper column 3. The rubber head at the air storage chamber near the other end of the dropper head extends out of the top of the large ring. The liquid inlet head at the end of the dropper column extends into the bottle body through the bottle mouth. The large ring is a snap-fit ​​ring. The outer diameter ring 201 at the bottom of the snap-fit ​​ring is provided with an inner diameter ring 202 that is lower than the height of the outer diameter ring. The bottle mouth has a bottle mouth fastening position 401 with a protrusion forming an inverted ring on the outer diameter. The bottle mouth fastening position has a protruding large ring fastening position 203 on the inner wall of the inner diameter ring of the snap-fit ​​ring. When the large ring fastening position of the snap-fit ​​ring is engaged with the bottle mouth fastening position of the bottle body to close the bottle mouth, the outer diameter ring of the snap-fit ​​ring abuts against the shoulder 402 below the bottle mouth and deforms outward.

[0028] Furthermore, the bottle body is either a blow-molded bottle body 4 or an injection-molded bottle body 5, wherein the bottom opening of the injection-molded bottle body is fastened and sealed to the injection-molded bottom cap 6. The connection between the bottom opening of the bottle body and the injection-molded bottom cap is provided with a multi-stage reflux structure through at least two fastening grooves.

[0029] Furthermore, the dropper column described above has two symmetrically arranged side through holes 301 on the arc surface of the hemispherical head above the central through hole at the end of the liquid inlet head. The side through holes are rectangular.

[0030] In use, when you pinch the outer diameter of the large buckle ring, squeezing it firmly will transfer the force through the angled direction to the central buckle rib. This causes the large buckle 102 to cleverly deform, separating it from the bottle opening buckle, thus achieving this function and making it convenient for consumers to use. The novelty and innovation of this structure lies in the fact that most products on the market open and close using a screw-on mechanism. This structure significantly reduces the time required for customers to open and close the device, making it much more convenient to use.

[0031] Based on the above structural characteristics, such as Figure 9 As shown, the bottle body has a raised retaining ring 4021 on its shoulder. When the large ring of the buckle is engaged with the bottle mouth buckle to close the bottle mouth, the outer diameter of the large ring abuts against the shoulder below the bottle mouth and deforms outward. Simultaneously, the opening at the outer diameter of the large ring abuts against and is limited by the retaining ring. Furthermore, the inner shoulder of the retaining ring has an annular groove 4022, in which a sealing ring 7 is embedded. When the large ring of the buckle is engaged with the bottle mouth buckle to close the bottle mouth, the outer diameter of the large ring slides into the annular groove and abuts against the sealing ring within the annular groove, deforming outward. The retaining ring and the annular groove, while limiting the deformation at the outer diameter of the large ring, simultaneously seal the bottle and prevent further spillage and contamination of the bottle. Based on the above structural features, an equally spaced, annular toothed ring is provided at the bottom of the annular groove on the shoulder. When the large ring of the buckle is engaged with the bottle mouth buckle to close the bottle mouth, the outer diameter of the buckle and the shoulder below the bottle mouth slide into the annular groove and abut against the toothed ring in the annular groove until they are locked and stopped, thereby further improving the locking and stopping action between the outer diameter ring and the shoulder.

[0032] Based on the above structural characteristics, such as Figures 10-11As shown, an outer cover 8 is provided on the outside of the rubber dropper head at the top of the aforementioned buckle ring. The opening of the outer cover is fitted with or threaded to the protruding boss at the top of the buckle ring. The rubber dropper head is located in the anti-pressure cavity of the outer cover. The outer cover includes a lower cover shell 801, an upper cover shell 802, and an inner plug sleeve 803. The rubber dropper head is fitted into the anti-pressure cavity of the inner plug sleeve. One end of the inner plug sleeve is interference-fitted past the limiting rib located on the inner diameter of the bottom of the lower cover shell. The other end of the inner plug sleeve extends out of the center hole at the top of the lower cover shell and is fastened to the upper cover shell. The top opening of the upper cover shell abuts against the bottom opening of the lower cover shell for limitation. The lower cover shell and the upper cover shell are connected by the inner plug sleeve to form an integral outer shell.

[0033] Furthermore, the inner sleeve is provided with a partition 8031 ​​that abuts against the top of the rubber dropper head. Above the central vent hole at the partition, the inner sleeve is provided with a secondary cavity. Below the point where the inner sleeve and the rubber dropper head fit together, there is a lower cavity that accommodates the longitudinal deformation of the rubber dropper head and expands outward. After opening the upper cover, pressing the top of the inner sleeve keeps the inner sleeve and the rubber dropper head fitted together, while the inner sleeve causes the rubber dropper head to deform.

[0034] When using, simply open the outer cap to access the rubber dropper head. The method of using the rubber dropper head is to squeeze it to draw liquid from the bottle into the dropper column. Alternatively, if only the top cover of the outer cap is opened, the protruding inner stopper can also be pressed to deform the rubber dropper head and draw liquid from the bottle. However, the amount of liquid drawn by pressing the rubber dropper head is less than the amount drawn by squeezing it after opening the outer cap.

[0035] Based on the above structural features, the dropper bottle comes in four models: 30ml blow-molded bottle, 30ml injection-molded bottle, 50ml blow-molded bottle, and 50ml injection-molded bottle.

[0036] The above description is intended to illustrate the technical means of the present invention and is not intended to limit the scope of the invention. Any obvious improvements or substitutions made to the present invention by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of the present invention.
