Description

Technical Field

[0001] This application relates to the field of cosmetic packaging, and in particular to a dropper-type packaging bottle. Background Technology

[0002] For liquid cosmetics applied topically, the fluidity of the liquid makes it difficult to precisely control the application. To make these products easier to use, a dropper that connects to the cosmetic container is recommended. Simply draw up the cosmetic through the dropper and apply it to the desired area. This method is both time-saving and precise. Currently, most droppers for cosmetics use a manual method of pressing the rubber tip to dispense the liquid.

[0003] To facilitate easier liquid dispensing, packaging bottles with automatic dispensing capabilities have been introduced on the market. For example, a mechanically spun-type dropper cap and dropper bottle are disclosed in announcement number CN217649984U. The dropper cap includes an outer sleeve, an inner cap, a rubber cap, a push cap, and a dropper. The outer sleeve is fitted onto the inner cap and is rotatably connected to the inner cap along its axis. The rubber cap is connected to the inner cap, and the push cap and dropper are respectively connected to both ends of the rubber cap along the axis of the inner cap. The push cap is slidably connected to the inner cap along its axis. The outer sleeve is used to rotate relative to the inner cap under the action of external force and abut against the push cap to drive the push cap to move closer to the dropper, thereby compressing the rubber cap.

[0004] The dropper bottle described above can automatically dispense liquid during the actual opening / closing process, but the cap and inner cap are assembled using a snap-fit ​​structure, which is a rather cumbersome assembly method and needs further improvement. Utility Model Content

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a system, product, or device that includes a series of units is not necessarily limited to those units that are explicitly listed, but may include other units that are not explicitly listed or that are inherent to such products or devices.

[0038] See Figures 1-6 One embodiment of this application provides a dropper-type packaging bottle, including a bottle body 100, a cap 200, and a liquid-absorbing device 300. The bottle body 100 is used to hold cosmetics and includes a bottle head 110 and a bottle body 120. The bottle head 110 has an external thread 115. The top of the cap 200 is open and has a movably disposed pressing cap 330. The inner wall of the cap 200 has an internal thread 222 that mates with the external thread 115. The liquid-absorbing device 300 includes a deformable liquid-absorbing capsule 310 fixedly connected to the pressing cap 330 and a dropper 320 whose top end is connected to the liquid-absorbing capsule 310 and whose bottom end extends into the interior of the bottle body 120. Preferably, the liquid-absorbing capsule 310 has a wavy structure, which can increase the suction force of the liquid-absorbing capsule 310 to facilitate liquid absorption.

[0039] In the existing liquid suction device 300 and cover 200, the liquid suction bladder is generally axially limited to the inner cover 220 by a snap-fit ​​structure. For example, an annular groove is provided at the bottom of the liquid suction bladder, and an annular protrusion that matches the annular groove is provided in the inner cover 220. The annular groove and the annular protrusion cooperate to achieve axial limitation. In order to prevent the liquid suction bladder from detaching from the inner cover during transportation or use, the snap-fit ​​structure of the two is relatively deep. In actual assembly, the annular protrusion is not easy to engage into the annular groove, and there is even a risk of damaging the snap-fit ​​structure.

[0040] To address this issue, the liquid suction pod 310 of this application has a first base 311 at its bottom, a second base 321 at the top of the dropper 320, and a protrusion 221 on the cover 200. The first base 311 and the second base 321 are connected to clamp the protrusion 221, thus axially fixing the liquid suction device 300 and the cover 200. Therefore, compared to the prior art, the assembly of the liquid suction device 300 and the cover 200 of this application is simpler and easier to operate.

[0041] Regarding the connection between the first base 311 and the second base 321, they are connected by a plug-in joint. Specifically, the first base 311 has a first through hole 312 communicating with the suction capsule 310, and the second base 321 has a second through hole 313 communicating with the dropper 320. The top of the second base 321 is inserted into the first through hole 312 to achieve an interference fit, and the second through hole 313 is connected to the outlet of the suction capsule 310. Therefore, when the suction capsule 310 is pressed, air can be expelled, and when the pressing force is released, cosmetics can be drawn from the bottle 100 into the dropper 320.

[0042] Of course, in order to make the fit between the inner cover 220 and the second base 321 more secure, an annular groove 322 can also be provided. Correspondingly, the protrusion 221 extends inward to form an extension 224 that fits with the annular groove 322. The snap-fit ​​structure of the two is relatively shallow, and they can fit together more easily.

[0043] See Figures 1-4 The cover 200 includes an outer cover 210 and an inner cover 220. The inner cover 220 has an internal thread 222. A gap is provided between the outer cover 210 and the inner cover 220. The lower part of the press cap 330 is fitted into the gap, and the upper part protrudes from the outer cover 210.

[0044] Furthermore, the outer cover 210 and the inner cover 220 can rotate relative to each other. For example, one of the outer cover 210 and the inner cover 220 may be provided with a circumferentially arranged latching protrusion 213, and the other may be provided with an annular groove 225. In the figure, the latching protrusion 213 is provided on the inner wall of the outer cover 210, and the annular groove 225 is provided on the outer wall of the inner cover 220.

[0045] A circumferential limiting mechanism is provided between the pressing cap 330 and the inner cover 220 to allow the pressing cap 330 to move axially relative to the inner cover 220. In the figure, axially extending positioning ribs 226 are arranged on the outer wall of the inner cover 220, and correspondingly, a groove 332 is arranged on the inner wall of the pressing cap 330. Considering the stability of the structure during mating, there are two positioning ribs 226 and two grooves 332, arranged symmetrically.

[0046] To enable automatic cosmetic suction, the inner wall of the outer cover 210 is provided with a spiral bevel 211, and the outer wall of the pressing cap 330 is provided with a protrusion 331 that mates with the spiral bevel 211. During the tightening of the outer cover 210 and the inner cover 220, the pressing cap 330 is driven to move downwards to compress the suction capsule 310. This compression of the suction capsule 310 expels air, facilitating the suction of liquid.

[0047] Furthermore, the inner wall of the outer cover 210 is provided with a limiting part 212 that cooperates with the protrusion 331 to limit the rotation angle of the outer cover 210. Specifically, there are two spiral inclined surfaces 211 and two protrusions 331, which are arranged symmetrically. The limiting part 212 is located at both ends of the spiral inclined surface 211, so that the pressing cap 330 has a highest end and a lowest end. The spiral inclined surface 211 is opposite to the spiral direction of the external thread 115 and the internal thread 222.

[0048] When the bottle body 100 and the cap body 200 are screwed on, the outer cap 210 rotates circumferentially relative to the inner cap 220. At this time, the spiral inclined surface 211 guides the protrusion 331 to move to the bottom, and the corresponding pressing cap 330 moves downward to compress the suction capsule 310, expelling the air in the suction capsule 310. When the bottle body 100 and the cap body 200 are unscrewed, the spiral inclined surface 211 on the outer cap 210 guides the protrusion 331 to move to the top. At this time, the pressing cap 330 moves upward, and the suction capsule 310 returns to its original position, thus drawing the cosmetics in the bottle body 100 into the dropper 320, thereby realizing the automatic suction function.

[0049] To ensure that the pressing cap 330 is at the lowest end of the spiral slope 211 when the liquid suction device 300 is tightened, and that the liquid suction capsule 310 is at the highest end of the spiral slope 211 before the liquid suction device 300 is unscrewed to reposition and absorb cosmetics, a rib 116 is axially arranged at the bottom end of the external thread 115. Correspondingly, the bottom of the internal thread 222 has a positioning groove 223 that mates with the rib 116.

[0050] See Figure 8The bottle head 110 is provided with a bottle mouth 111, and an inner stopper 112 is arranged inside the bottle mouth 111. The inner stopper 112 is partially radially narrowed to form a scraping part 113 that fits with the dropper 320 with a clearance. The scraping part 113 is provided with a dispensing window 114. When the liquid suction device 300 is pulled out from the bottle body 100, the cosmetic residue on the outer wall of the dropper 320 can flow out from the dispensing window 114 under the action of the scraping part 113, avoiding the problem of residue inside the inner stopper 112.

[0051] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0052] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
