Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a reusable double-layered cream packaging bottle, including an outer shell 1 and an outer shell cap 2 movably installed on the top of the outer shell 1. The inner shell 1 has a placement groove 3, and a ring plate 4 is fixedly connected to the upper inner side of the outer shell 1. A fixing hole 5 is opened at the top of the ring plate 4. An inner bottle 6 is movably engaged inside the placement groove 3, and a fixing component 7 located above the inner bottle 6 is movably engaged at the top of the ring plate 4. The fixing component 7 includes a pressure ring 71, which is engaged at the top of the ring plate 4. A locking post 73 is fixedly connected to the bottom of the pressure ring 71, and a protrusion 74 is fixedly connected to the bottom of the locking post 73. The internal part of the locking post 73 is provided with a squeezing groove 75, which is movably engaged with the inside of the fixing hole 5. When the pressure ring 71 is pulled upward, it moves upward, causing the protrusion 74 in the fixing hole 5 to be squeezed and deformed towards the squeezing groove 75, thereby pulling the protrusion 74 out of the fixing hole 5, realizing the disassembly of the pressure ring 71, releasing the restriction on the inner bottle 6, and the inner bottle 6 can be taken out for replacement. By aligning the protrusion 74 with the fixing hole 5, the pressure ring 71 is pressed down to make it deform and engage with the limiting pressure ring 71 inside the fixing hole 5. The pressure ring 71 limits and fixes the inner bottle 6 to complete the replacement. It can be reused through the fixing component 7, without the need for additional processing of the inner bottle 6, thus improving economy.

[0024] The locking posts 73 are arranged in a ring at equal intervals at the bottom of the pressure ring 71. The positions of the fixing holes 5 are corresponding to the locking posts 73. The ring-shaped and equidistant distribution of the locking posts 73 ensures the uniformity of force on the pressure ring 71 during installation and disassembly, thereby improving the overall stability of the fixing component 7. The corresponding arrangement of the fixing holes 5 and the locking posts 73 simplifies the operation steps and enhances the positioning accuracy of the inner bottle 6 in the placement groove 3, effectively avoiding loosening or displacement caused by external forces. At the same time, it also makes it easier for users to quickly identify the matching positions of the locking posts 73 and the fixing holes 5, improving the convenience of actual use.

[0025] The bottom of the pressure ring 71 is provided with a stepped groove 72, and the inner bottle 6 is set inside the stepped groove 72. The stepped groove 72 allows the inner bottle 6 to be more securely embedded in the pressure ring 71 during installation, avoiding displacement caused by external impact or vibration. At the same time, the inner side of the stepped groove 72 is smooth, reducing the friction between it and the inner bottle 6, making disassembly smoother. It can also effectively disperse the pressure distribution of the pressure ring 71 during the force process, improving reliability.

[0026] The top of the pressure ring 71 is fixedly connected to a buckle plate 76 arranged in a ring at equal intervals. The buckle plate 76 provides a force application point in actual operation, making it convenient for users to install and remove. The top of the buckle plate 76 is provided with anti-slip texture, which increases the friction when the fingers are in contact with it and can also effectively avoid operation errors caused by wet or oily hands. The buckle plate 76 is made of high-strength plastic, which ensures its durability.

[0027] The outer side of the protrusion 74 is arc-shaped. The arc-shaped transition design of the outer side of the protrusion 74 allows the protrusion 74 to deform against the inner wall of the fixing hole 5 when the user pulls or presses the pressure ring 71. This makes it easy for the user to stably insert or pull the protrusion 74 into or out of the fixing hole 5 when applying force, ensuring that the amount of force applied by the user is appropriate, so as not to damage the structure and to ensure the limiting and fixing effect of the inner bottle 6.

[0028] Please see Figure 2 and Figure 5 The inner bottle 6 is movably secured to the top of a sealing cap 8. The bottom of the sealing cap 8 has a cover plate 81, and a silicone ring 82 is movably secured to the inner side of the cover plate 81. The outer cap 2 includes a cap body 21, with a retaining ring 22 at the bottom and a threaded groove 23 on the inner side of the cap body 21. The cap body 21 is threaded to the top of the outer cap 1 through the threaded groove 23. The silicone ring 82 inside the cover plate 81 fits into the annular groove on the inner bottle 6. After the cap body 21 is tightened above the outer cap 1, the retaining ring 22 on the inner side of the cap body 21 presses against the cover plate 81. The retaining ring 22 presses and limits the cover plate 81 while squeezing the silicone ring 82 to ensure a tight fit with the inner bottle 6, thus improving the sealing effect.

[0029] The diameter of the abutment ring 22 corresponds to the diameter of the silicone ring 82, which ensures that the abutment surface of the ring 22 is evenly stressed, avoiding seal failure due to insufficient local pressure, thereby improving the overall sealing performance.

[0030] Working principle: The cap 21 can be removed by screwing it on. The inner bottle 6 can be opened and accessed by pulling out the cap plate 81 and causing the silicone ring 82 to detach from the inner bottle 6. After closing, the silicone ring 82 inside the cap plate 81 fits into the annular groove on the inner bottle 6. After the cap 21 is tightened above the outer shell 1, the abutment ring 22 on the inner side of the cap 21 presses against the cap plate 81. The abutment ring 22 presses and limits the cap plate 81 while squeezing the silicone ring 82 to ensure that it fits tightly with the inner bottle 6, thus improving the sealing effect.

[0031] When replacing the inner bottle 6, the buckle plate 76 is pulled upward to move the pressure ring 71 upward. The upward movement of the pressure ring 71 moves the protrusion 74, which is stuck in the fixing hole 5, upward. The protrusion 74 is subjected to tension and is squeezed into the extrusion groove 75, causing it to deform and shrink inward. The protrusion 74 can then be pulled out of the fixing hole 5 to remove the pressure ring 71. After removing the pressure ring 71, the restriction on the inner bottle 6 is released, and the inner bottle 6 can be taken out of the placement groove 3 for replacement. Then, the protrusion 74 is pressed down on the pressure ring 71 corresponding to the fixing hole 5, causing it to deform and be stuck into the interior of the fixing hole 5. The protrusion 74, located in the fixing hole 5, expands outward to limit the pressure ring 71. The pressure ring 71 limits and fixes the inner bottle 6, completing the replacement. The fixing component 7 can be reused, and no additional processing of the inner bottle 6 is required, improving economy. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
