Description

Technical Field

[0001] This application relates to the field of cosmetic packaging, and in particular to a packaging bottle for powder cosmetics. Background Technology

[0002] In existing powder cosmetic packaging, the box body and powder sieve are generally connected by snap-fit ​​or threaded connections. For example, patent document CN208798760U discloses a new type of leak-proof detachable loose powder box, which includes an upper lid and a loose powder base box. The loose powder base box has a loose powder cavity, and a powder dispensing box is installed on the loose powder cavity inside the loose powder base box. A sealing powder cover is connected to the powder dispensing box, and a sealing fastening ring is provided on the outer wall of the powder dispensing box. A lifting buckle is provided at the front end of the powder placement cavity, and a powder support ridge is provided on the bottom surface of the powder placement cavity. A sealing leak-proof ridge is provided at the bottom of the sealing powder cover, and a sealing locking groove that cooperates with the sealing leak-proof ridge is provided on the inner edge of the powder dispensing hole.

[0003] However, the above materials are generally made of plastic. Considering environmental protection issues, the plastic powder sieves are now being replaced with metal. However, metal powder sieves are not flexible and are not suitable for snap-fit ​​connections. If an interference fit is used, it will affect the assembly of other accessories.

[0004] To address this issue, refer to the packaging bottle for a powdered cosmetic disclosed in publication number CN218551622U. A V-shaped sealing ring is fitted in the gap between the bottle mouth and the powder sieve to achieve a sealed packaging bottle through interference fit. However, when this type of sealing ring is actually fitted, the overall interference is relatively large, which increases the assembly difficulty and may damage the powder sieve during disassembly. Therefore, further improvements are needed. Utility Model Content

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.

[0038] 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.

[0039] 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.

[0040] See Figures 1-5 One embodiment of this application provides a packaging bottle for powder cosmetics, including a bottle body 100, a powder sieve 200, and a sealing ring 300.

[0041] The bottle 100 is used to hold powdered cosmetics and includes a bottle body 110 and a bottle mouth 120. The bottle mouth 120 has an inner peripheral surface 121 and an outer peripheral surface 122. The powder sieve 200 is formed by stamping a metal sheet and includes a cylindrical side wall 210 and a flat bottom wall 220 with powder outlet holes 221. There is a gap 230 between the side wall 210 and the inner peripheral surface 121 of the bottle mouth 120. The number of powder outlet holes 221 is multiple and they are arranged in a circle around the center of the bottom wall 220. Of course, the size and number of powder outlet holes 221 can be set according to needs, and this application does not make any special requirements. In this embodiment, the powder sieve 200 is preferably made of aluminum.

[0042] Of course, a typical packaging bottle also includes a cap 400, a gasket 410 fitted onto the cap for sealing, and a sealing film 420 to prevent powdered cosmetics from overflowing from the powder outlet after filling. The cap 400, gasket 410, and sealing film 420 are not the focus of this improvement, and will not be described in detail here.

[0043] Although existing packaging bottles also use sealing ring 300 to assemble bottle body 100 and powder sieve 200, the overall interference during actual assembly is large, which increases the assembly difficulty and may damage the powder sieve during disassembly.

[0044] Therefore, in order to solve the above problems, the sealing ring 300 of this application includes a main body 310, which is assembled in the gap 230 and is provided with a protrusion 320 that is interference-fitted with the outer peripheral surface 122.

[0045] The sealing ring 300 of the packaging bottle of this application uses a protrusion 320 to interfere with the outer peripheral surface 122. By setting the protrusion 320, the interference amount can be controlled to ensure a suitable separation force, which makes assembly more convenient compared with the prior art.

[0046] In this embodiment, preferably, the sealing ring 300 is made of nitrile rubber and the bottle body 100 is made of glass.

[0047] To ensure more even stress distribution after assembly, multiple protrusions 320 are provided and evenly distributed along the circumference of the main body 310. Of course, the number of protrusions 320 can be adjusted according to requirements; for example, in the illustration, there are three protrusions 320.

[0048] See Figures 3-6 The sealing ring 300 has an outer side 301 that mates with the inner circumferential surface 121 and an inner side 302 that is interference-fitted with the sidewall 210 of the powder sieve 200. The protrusion 320 is located on the outer side 301. The inner side 302 is provided with a clearance area 303 that is clearance-fitted with the sidewall 210 at the position opposite to the protrusion 320. On the outer side 301, only the position of the protrusion 320 is interference-fitted with the inner circumferential surface 121, while the other positions are clearance-fitted.

[0049] When the protrusion 320 is pressed against the inner circumferential surface 121, the clearance area 303 deforms under the pressure, causing the edge of the clearance area 303 to also fit tightly against the powder sieve 200, achieving an interference fit. Therefore, the interference amount can be controlled within an appropriate range by controlling the diameter of the protrusion 320 of the sealing ring 300, the fit tolerance between the sealing ring 300 and the powder sieve 200, and the fit tolerance between the sealing ring 300 and the bottle.

[0050] In one embodiment, the inner circumferential surface 121 includes a sealing section 123 that is interference-fitted with the sealing ring 300, a reduced-diameter limiting section 124, and an expanded-diameter section 125 that connects to the bottle body 110. The outer circumferential surface 122 is threaded and can be threadedly connected to the cap 400. For ease of assembly, the bottle opening 120 and / or the main body 310 are provided with chamfers 330. Preferably, both the bottom of the main body 310 and the bottle opening 120 are provided with chamfers 330 to facilitate assembly.

[0051] Furthermore, the sealing ring 300 includes a first flange 340 disposed at the top of the main body 310 and folded outward, the first flange 340 abutting against the end face of the bottle mouth 120; the powder sieve 200 has a second flange 240 folded outward, the second flange 240 abutting against the first flange 340. This design allows the first flange 340 to be clamped between the second flange 240 and the end face of the bottle mouth 120, that is, the first flange 340 is compressed and deformed to form an end face seal, achieving the airtightness requirement. Furthermore, the second flange 240 does not directly contact the end face of the bottle mouth 120, which can better protect the powder sieve 200 during disassembly.

[0052] Preferably, the second flange 240 covers the first flange 340. This makes the overall shape more aesthetically pleasing and also makes it easier to pick up the second flange 240 for disassembly.

[0053] Preferably, in the axial direction, the ratio of the height of the main body 310 to the height of the protrusion 320 is 1:0.5 to 0.8, and the ratio of the thickness of the main body 310 to the thickness of the protrusion 320 is 1:0.38 to 0.55.

[0054] During assembly, first, place the sealing ring 300 around the outer periphery of the powder sieve 200 (at this time, the inner side 302 of the sealing ring is interference-fitted with the powder sieve 200 and will not fall off). Then, install the above-mentioned components inside the bottle body 100. At this time, because the outer side 301 of the sealing ring 300 is clearance-fitted with the inner peripheral surface 121, the sealing ring 300 can be easily inserted into the bottle mouth 120 until the protrusion 320 abuts against the inner peripheral surface 121. Then, continue to apply force to press the sealing ring 300 into the bottle mouth 120 (the avoidance area 303 deforms and is interference-fitted with the powder sieve 200) until the first flange 340 is tightly clamped between the second flange 240 and the end face of the bottle mouth 120, thus completing the installation.

[0055] The packaging bottle for powder cosmetics provided in this application has protrusions on the main body that are interference fit with the outer circumferential surface of the bottle mouth, which can control the amount of interference and facilitate assembly. The design of the first flange not only ensures the sealing performance but also prevents damage to the powder sieve during disassembly.

[0056] 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.

[0057] 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.
