Description

Technical Field

[0001] This application relates to the field of cosmetic packaging, and in particular to a cosmetic packaging bottle with a replaceable inner liner. Background Technology

[0002] Cosmetic packaging bottles are used to hold cosmetics, but they are generally discarded after use because they cannot be reused, which is not environmentally friendly. With social development, environmental protection and sustainable development have become new trends in the cosmetic packaging industry. Therefore, packaging bottles with replaceable inner liners have been launched on the market. For example, document CN 218432340 U discloses a packaging bottle with a replaceable inner bottle, including an outer cap, an inner cap, a shoulder sleeve, an outer bottle, and a replaceable inner bottle. The outer bottle is open at both the top and bottom. The outer cap is connected to the shoulder sleeve through the inner cap. The shoulder sleeve is snapped into the outer bottle. The replaceable inner bottle can be inserted into the inner cavity of the outer bottle from the bottom. The upper part of the replaceable inner bottle is placed inside the shoulder sleeve. The middle part of the replaceable inner bottle is provided with a buckle strip. The inner side of the outer bottle is provided with a limiting protrusion. The buckle strip can be snapped into the limiting protrusion.

[0003] Although the aforementioned packaging bottle can replace the inner liner, its overall structure is complex and not convenient enough when replacing the inner liner, requiring further improvement. Utility Model Content

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.

[0028] 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.

[0029] See Figures 1-5 One embodiment of this application provides a cosmetic packaging bottle with a replaceable inner liner 200, including an outer bottle 100 and an inner liner 200 disposed inside the outer bottle 100. The top and bottom of the outer bottle 100 are open, and the inner liner 200 extends into the inner cavity of the outer bottle 100 from the top.

[0030] The inner liner 200 includes a body portion 210 for holding cosmetics and a reduced-diameter portion 220 that is radially narrower than the body portion 210. The body portion 210 has a side wall 211 and a bottom wall 212. The reduced-diameter portion 220 protrudes from the bottom wall 212. The outer bottle 100 includes a cylindrical portion 110 adapted to the side wall 211 (in the figure, the two are in a clearance fit) and a radially extending portion 120 that bends inward relative to the cylindrical portion 110 and is adapted to the bottom wall 212. The cylindrical portion 110 defines a top opening 101 of the outer bottle 100, and the radially extending portion 120 defines a bottom opening 102 of the outer bottle 100. The reduced-diameter portion 220 extends into the bottom opening 102 and is provided with an engaging structure between itself and the radially extending portion 120.

[0031] In order for the reduced diameter portion 220 to smoothly extend into the bottom opening 102, the reduced diameter portion 220 and the radial extension portion 120 are fitted with a clearance.

[0032] The engaging structure includes a latching protrusion 121 disposed on one of the radial extension 120 and the reduced diameter portion 220, and a latching groove 221 disposed on the other. The latching groove 221 includes a circumferentially extending engaging portion 222 and an axially extending guide portion 223 connecting the engaging portion 222. The guide portion 223 extends to the edge of the radial extension 120 or the reduced diameter portion 220 to form an inlet 224. Preferably, the engaging portion 222 has two ends, specifically a first end 226 and a second end 227, wherein the guide portion 223 engages with the first end 226.

[0033] In this embodiment, preferably, the latching protrusion 121 is disposed on the radially extending portion 120. Specifically, the latching protrusion 121 is a protrusion that starts from the peripheral wall of the bottom opening 102 and extends radially, and the latching groove 221 is disposed on the reduced diameter portion 220. Of course, considering the stability of the structure, there are multiple latching protrusions 121 and corresponding latching grooves 221. For example, in the figure, there are two in total, arranged symmetrically. Since the latching protrusion 121 is a radial protrusion, the reduced diameter portion 220 cannot smoothly extend into the bottom opening 102 when the guide portion 223 is not aligned with the latching protrusion 121.

[0034] In order to keep the protrusion 121 at one end of the slot 221 and prevent the protrusion 121 from rotating relative to the slot 221 due to external factors such as transportation and drops, the side wall 211 of the engaging part 222 protrudes to form a stop part 225, which is located near the second end 227.

[0035] Of course, to facilitate assembly or disassembly, the locking protrusion 121 should pass over the stop portion 225, see [reference needed]. Figure 5 The two sides of the convex 121 have guide slopes.

[0036] See Figure 4The reduced diameter section 220 is a hollow structure with an open bottom, and the bottom surface of its cavity is provided with an operating part for operating the rotation of the inner liner 200. Furthermore, the operating part is a rib 240 protruding from the bottom surface, and the two ends of the rib 240 extend to the side wall 211 of the cavity. Preferably, there are two ribs 240, which makes it easier for the hand to grip and apply force, and also disperses the force applied to the ribs 240 during rotation, making the structure more stable.

[0037] Furthermore, the rib 240 is hidden in the cavity, making the overall shape more aesthetically pleasing.

[0038] When assembling the inner liner 200 and the outer bottle 100, the inner liner 200 is directly inserted into the top opening 101 of the outer bottle 100 until the narrowed section 220 abuts against the radial extension section 120 (generally, the locking protrusion 121 and the guide section 223 are difficult to align, at which point the narrowed section 220 abuts against the locking protrusion 121, and the narrowed section 220 cannot smoothly extend into the bottom opening 102). Then, the inner liner 200 is rotated relative to the outer bottle 100. During the rotation, when the locking protrusion 120... When the inner liner 200 is aligned with the inlet 223, the locking protrusion 121 can smoothly enter the inlet 223 from the inlet port 224. Correspondingly, the reduced diameter part 220 smoothly extends into the bottom opening 102. Then, the inner liner 200 is rotated relative to the outer bottle 100. At this time, the locking protrusion 121 moves along the locking part 222 until it abuts against the stop part 225. Then, force is applied until the locking protrusion 121 passes the stop part 225 and is held at the second end 227 of the locking part 222, thus completing the assembly of the two.

[0039] When it is necessary to disassemble the inner liner 200 and the outer bottle 100, hold the protruding rib 240 with one hand and the outer bottle 100 with the other hand. Then apply a force opposite to that used during assembly to the protruding rib 240. Under the action of a larger force, the locking protrusion 121 will extend beyond the stop part 225, allowing the inner liner 200 to rotate relative to the outer bottle 100 until the locking protrusion 121 abuts against the first end 226. Then apply axially opposite forces to the inner liner 200 and the outer bottle 100. At this time, the protrusion will disengage from the guide part 223, thus achieving the disassembly of the two.

[0040] In this embodiment, since the radial extension 120 needs to engage with the reduced diameter portion 220, the structural strength requirement of the radial extension 120 is higher. Preferably, the thickness of the radial extension 120 is greater than the thickness of the cylindrical portion 110.

[0041] Furthermore, the inner liner 200 has a flange 230 that rests on the top opening 101 of the outer bottle 100. The flange 230 makes the appearance more aesthetically pleasing and makes it easier to remove the inner liner 200 when disassembling it. Of course, the design of this locking structure reduces the force between the flange 230 and the top of the outer bottle 100 during assembly, making it less prone to damage.

[0042] The structure of the cosmetic packaging bottle with a replaceable inner liner of this application is simpler than that of the prior art, and there is no need to precisely align the protrusion 121 with the inlet 223 when assembling the inner liner 200, making the operation more convenient.

[0043] 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.

[0044] 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.
