Description

Technical Field

[0001] This utility model relates to the field of cosmetic containers, and in particular to a replaceable cosmetic container and a non-collinear sealing structure. Background Technology

[0002] Based on the EU's plastic ban, the various cosmetic containers currently used in the EU have gradually been replaced by a long-term metal outer bottle with a replaceable disposable inner bottle structure. The inner bottle is made of non-plastic products to reduce the cost of using the products for consumers.

[0003] To facilitate the removal of the inner bottle, most components of these replaceable lotion bottles are connected by threads, which also provide reliable pre-tightening force to seal the interface area. Some replaceable lotion bottles have a cap that presses down on the dispensing area to seal the outlet; therefore, the cap also uses a screw connection. This connection method is simple and does not affect the required clamping force for sealing due to repeated disassembly. For example, the ball bearing packaging bottle (patent PCT / CN2023 / 118942) requires the internal structure of the cap to press the ball bearing for sealing when not in use. This type of structure results in a larger thread tightening force. During normal use, opening the bottle can easily cause the threads between the outer bottle and the cap to rotate, leading to the need to disassemble the replaceable lotion bottle for non-disassembly replacement, causing inconvenience.

[0004] The existing Chinese patent CN220001091U, "Replaceable Cosmetic Container and Replaceable Inner Bottle," discloses a structure that restricts the rotation of the inner liner. To prevent rotation problems, a spiral guide groove and a limiting component are set to achieve relative fixation between the inner liner and the outer bottle. However, this restriction method is not entirely applicable to some replaceable lotion bottles. Therefore, a lotion bottle sealing structure with high reliability that can be applied to various lotion bottles is needed. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a replaceable non-collinear sealing structure for cosmetic containers. This non-collinear sealing structure is provided with two locking mechanisms with different force directions. The two locking mechanisms are respectively applied between the bottle cap and the emulsion delivery mechanism and between the emulsion delivery mechanism and the outer bottle, so that when one is opened, the other will not be opened at the same time, thus improving the reliability of use.

[0006] This utility model is implemented as follows: a replaceable cosmetic container non-collinear sealing structure includes an outer bottle, an emulsion delivery mechanism, and a cap. The outer bottle is provided with a cavity for placing a replacement inner bottle. The inlet end of the emulsion delivery mechanism is connected to the outer bottle through a first locking mechanism. The cap is fitted onto the coating end of the emulsion delivery mechanism, and the cap is connected to the emulsion delivery mechanism through a second locking mechanism. The first and second locking mechanisms are movable locking mechanisms. The emulsion delivery path of the emulsion delivery mechanism is taken as the X-axis, and a straight line on a plane perpendicular to the X-axis is taken as the Y-axis. The unlocking force of the first and second locking mechanisms is selected from one of three directions: movement along the X-axis, rotation around the X-axis, and rotation around the Y-axis. The unlocking force directions of the first and second locking mechanisms are different.

[0007] When the unlocking force is oriented to rotate along the X-axis, the movable locking mechanism is a threaded locking mechanism; when the unlocking force is oriented to rotate around the Y-axis, the movable locking mechanism is a flip-top locking mechanism; when the unlocking force is oriented to move along the X-axis, the movable locking mechanism is a pressure cap sealing locking mechanism, a magnetic core sealing locking mechanism, or a snap-on sealing locking mechanism.

[0008] The first locking mechanism is a threaded locking mechanism that rotates around the X-axis, including a first external threaded ring and a first internal threaded ring. The first external threaded ring is disposed on the outer bottle, and the first internal threaded ring is disposed on the side of the emulsion conveying mechanism near the liquid inlet. The emulsion conveying mechanism is connected to the outer bottle by screwing on the thread. The second locking mechanism is a flip-cap locking mechanism, a pressure cap sealing locking mechanism, or a magnetic core sealing locking mechanism.

[0009] The first locking mechanism is a capping and sealing locking mechanism that moves along the X-axis, including a retaining ring and a retaining ring. The retaining ring is disposed on the outer bottle, and the retaining ring is disposed on the side of the emulsion delivery mechanism near the liquid inlet end. The second locking mechanism is a flip-cap locking mechanism or a threaded locking mechanism.

[0010] The first locking mechanism is a snap-on sealing locking mechanism that moves along the X-axis, including a snap-on button and a snap-on head. The snap-on head is located at the top opening of the outer bottle, and the snap-on button is located on the bottom outer ring of the emulsion delivery mechanism and cooperates with the snap-on head. The second locking mechanism is a flip-top locking mechanism or a threaded locking mechanism.

[0011] A rotary locking mechanism is also provided between the outer bottle and the emulsion delivery mechanism. The rotary locking mechanism includes several vertical ribs, which are arranged in a circular array parallel to the X-axis on the outer ring of the outer bottle and the inner ring of the emulsion delivery mechanism. The gap between the vertical ribs matches the width of the root of the vertical rib.

[0012] The second locking mechanism is a magnetic core sealing locking mechanism that moves along the X-axis, including a magnetic ring and a metal ring. The magnetic ring is formed by an array of several small magnets in a ring on the bottle cap. The metal ring is set at the opening of the emulsion delivery mechanism and cooperates with the magnetic ring. The metal ring is made of ferromagnetic material. The first locking mechanism is a flip-cap locking mechanism or a threaded locking mechanism.

[0013] The second locking mechanism is a threaded locking mechanism that rotates around the X-axis, including a second internal threaded ring and a second external threaded ring; the first locking mechanism is a pressure cap sealing locking mechanism or a snap-lock sealing locking mechanism.

[0014] The second locking mechanism is a flip-top locking mechanism that rotates around the Y-axis, and the emulsion delivery mechanism is connected to one side of the outer wall of the bottle cap through a hinge assembly; the first locking mechanism is a threaded locking mechanism, a cap sealing locking mechanism, a magnetic core sealing locking mechanism, or a snap-on sealing locking mechanism.

[0015] A replaceable cosmetic container includes a collinear sealing structure. The emulsion delivery mechanism includes a ball bearing and an emulsion delivery channel with a sealing port. Part of the ball bearing is located within the emulsion delivery channel and engages with the sealing port, while the other part is exposed to form a coating end. When the cap is closed, the cap applies a pressing force directly or indirectly to the ball bearing to seal the sealing port.

[0016] The bottle cap includes an outer cap and an inner cap. The inner cap applies a clamping force to the ball bearing. The outer wall surface of the outer cap is on the same plane as the outer wall surface of the outer bottle.

[0017] This utility model relates to a replaceable cosmetic container non-collinear sealing structure. This non-collinear sealing structure is equipped with two locking mechanisms with different force directions. The two locking mechanisms are respectively applied between the bottle cap and the emulsion delivery mechanism and between the emulsion delivery mechanism and the outer bottle. This ensures that the emulsion delivery mechanism will not be accidentally disassembled when opening and closing the bottle cap during daily use, thereby improving the reliability of use and enhancing the user experience.

Detailed Implementation

[0028] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the description of the present invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims. Example

[0029] like Figure 1As shown, a non-collinear sealing structure for a replaceable cosmetic container includes an outer bottle 1, an emulsion delivery mechanism 3, and a cap 4. The outer bottle 1 has a cavity for placing a replacement inner bottle 2. The inlet end of the emulsion delivery mechanism 3 is connected to the outer bottle 1 via a first locking mechanism 5. The cap 4 is fitted onto the coating end of the emulsion delivery mechanism 3 and is connected to the emulsion delivery mechanism 3 via a second locking mechanism 6. The first locking mechanism 5 and the second locking mechanism 6 are movable locking mechanisms. The emulsion delivery path of the emulsion delivery mechanism 3 is taken as the X-axis, and a straight line on a plane perpendicular to the X-axis is taken as the Y-axis. The unlocking force of the first locking mechanism 5 and the second locking mechanism 6 is selected from one of three directions: movement along the X-axis, rotation around the X-axis, and rotation around the Y-axis. The unlocking force directions of the first locking mechanism and the second locking mechanism are different.

[0030] In this invention, different locking mechanisms are selected according to the direction of the unlocking force, so that the emulsion delivery mechanism 3 will not be disassembled when the bottle cap 4 is unlocked; when the direction of the unlocking force is rotation along the X-axis, the movable locking mechanism is a threaded locking mechanism; when the direction of the unlocking force is rotation around the Y-axis, the movable locking mechanism is a flip-cap locking mechanism; when the direction of the unlocking force is movement along the X-axis, the movable locking mechanism is a cap sealing locking mechanism, a magnetic core sealing locking mechanism, or a snap-on sealing locking mechanism. Example

[0031] like Figure 2 As shown, in this embodiment, the first locking mechanism is a threaded locking mechanism that rotates around the X-axis, including a first external threaded ring 11 and a first internal threaded ring 33. The first external threaded ring 11 is disposed on the outer bottle 1, and the first internal threaded ring 33 is disposed on the side of the emulsion conveying mechanism 3 near the inlet end. The emulsion conveying mechanism 3 is screwed onto the outer bottle 1. At this time, the second locking mechanism can be selected as follows: Figure 5 , 7 The flip-top locking mechanism, magnetic core sealing locking mechanism, or pressure cap sealing locking mechanism shown. Example

[0032] like Figure 3 As shown, in this embodiment, the first locking mechanism is a capping and sealing locking mechanism that moves along the X-axis, including a retaining ring 12 and a retaining ring 34. The retaining ring 12 is disposed on the outer bottle 1, and the retaining ring 34 is disposed on the side of the emulsion delivery mechanism 3 near the inlet end. At this time, the second locking mechanism can be selected as follows: Figure 6 , 7 The threaded locking mechanism or flip-top locking mechanism shown.

[0033] like Figure 9As shown, when the first locking mechanism is a cap sealing locking mechanism that moves along the X-axis, and the second locking mechanism is a mechanism that rotates around the X-axis to unlock, during the unlocking and locking process of the second locking mechanism, because the retaining ring 12 and the retaining ring 34 cannot provide sufficient rotational damping force, the outer bottle 1 and the emulsion delivery mechanism 3 will rotate together, affecting the use; even if the second locking mechanism is of other types, this rotation may still occur in daily use, affecting the user experience.

[0034] Therefore, in this embodiment, a rotation locking mechanism is also provided between the outer bottle 1 and the emulsion delivery mechanism 3. Preferably, the rotation locking mechanism includes a plurality of vertical ribs 62, which are arranged in a circular array parallel to the X-axis on the outer ring of the outer bottle 1 and the inner ring of the emulsion delivery mechanism 3. The gap between the vertical ribs 62 matches the width of the root of the vertical rib 62. After the retaining ring 12 and the retaining ring 34 are locked, each vertical rib 62 naturally meshes like gears, locking the degree of freedom of rotation of the outer bottle 1 and the emulsion delivery mechanism 3 around the X-axis. The specific locking method disclosed in this patent is only one embodiment and does not indicate that the specific locking structure is limited. Other embodiments that can limit the degree of freedom of rotation of the outer bottle 1 and the emulsion delivery mechanism 3 around the X-axis should also be protected by this patent as equivalent technical features.

[0035] like Figure 6 As shown, the second locking mechanism is a threaded locking mechanism that rotates around the X-axis, including a second internal threaded ring 42 and a second external threaded ring 31; the first locking mechanism is a pressure cap sealing locking mechanism or a snap-lock sealing locking mechanism.

[0036] like Figure 7 As shown, the second locking mechanism is a flip-top locking mechanism that rotates around the Y-axis, and the emulsion delivery mechanism 3 is connected to one side of the outer wall of the bottle cap 4 through a hinge assembly 61; the first locking mechanism is a threaded locking mechanism, a cap sealing locking mechanism, a magnetic core sealing locking mechanism, or a snap-on sealing locking mechanism. Example

[0037] like Figure 4 As shown, in this embodiment, the first locking mechanism is a snap-fit ​​sealing locking mechanism that moves along the X-axis, including a snap-fit ​​button 36 and a snap-fit ​​head 13. The snap-fit ​​head 13 is located at the top opening of the outer bottle 1, and the snap-fit ​​button 36 is located on the bottom outer ring of the emulsion delivery mechanism 3 and cooperates with the snap-fit ​​head 13. At this time, the second locking mechanism can be selected as follows: Figure 6 , 7 The threaded locking mechanism or flip-top locking mechanism shown. Example

[0038] like Figure 5As shown, in this embodiment, the second locking mechanism is a magnetic core sealing locking mechanism that moves along the X-axis, including a magnetic ring 41 and a metal ring 35. The magnetic ring 41 is formed by a ring array of several small magnets on the bottle cap 4. The metal ring 35 is disposed at the opening of the emulsion delivery mechanism 3 and cooperates with the magnetic ring 41. The metal ring 35 is made of ferromagnetic material. At this time, the first locking mechanism is as follows: Figure 2 The threaded locking mechanism or flip-top locking mechanism shown.

[0039] like Figure 8 As shown, a replaceable cosmetic container includes a collinear sealing structure. The emulsion delivery mechanism 3 includes a ball bearing 37. An emulsion delivery channel is provided inside the emulsion delivery mechanism 3. The emulsion delivery channel has a sealing port 32. Part of the ball bearing 37 is located inside the emulsion delivery channel and cooperates with the sealing port 32, while the other part is exposed to form a coating end. When the bottle cap 4 is closed, the bottle cap 4 applies a pressing force to the ball bearing 37 directly or indirectly to seal the sealing port 32.

[0040] In this embodiment, the bottle cap 4 includes an outer cap 43 and an inner cap 44. The bottle cap 4 applies a pressing force to the ball bearing 37 through the inner cap 44. The outer wall surface of the outer cap 43 is on the same plane as the outer wall surface of the outer bottle 1, making the overall shape of the product more aesthetically pleasing.
