Definitions

  • This disclosure relates to a technical field of packaging technology, and in particular to a bottle cap resistant to heat-induced removal and the fixed structure of its inner body and bottle neck.
  • Bottles typically consist of a bottle body and a bottle cap resistant to heat-induced removal. Generally, the wine is first filled into the bottle body, and then the bottle cap resistant to heat-induced removal is sealed on the neck of the bottle body.
  • Existing bottle cap resistant to heat-induced removal typically include a fixed component fixed to the bottle neck, a twist-off movable component, and an anti-counterfeiting structure positioned between the fixed component and the movable component. When opened for use, the anti-counterfeiting structure is irreparably damaged, achieving anti-counterfeiting by destroying the bottle cap.
  • the fixed component is usually secured to the bottle neck through snap fasteners and anti-rotation ribs, both made of plastic, heating the fixed component with a hairdryer or hot water can easily cause the snap fasteners and anti-rotation ribs to fail, allowing the fixed component to be easily removed. This enables counterfeiters to reuse bottles and bottle caps for fraudulent purposes, thereby compromising the anti-counterfeiting effectiveness.
  • a fixed structure of a bottle cap's inner body and bottle neck is provided, ensuring that the bottle cap cannot be removed without damage when heated, the fixed structure comprising:

  • the lower part of the fixing sleeve is equipped with multiple circumferentially arranged, collapsible claws, which can contract inward under the action of the lower end of the inner body, thereby tightly engaging with the first convex platform on the bottle neck.
  • the fixing sleeve and the inner plug are separable structures.
  • first anti-rotation structure between the fixing sleeve and the mounting segment to prevent relative rotational movement.
  • the first anti-rotation structure includes a second convex or concave portion on the outer wall of the fixing sleeve and a third concave or convex portion on the inner wall of the mounting segment, with the third concave or convex portion cooperating with the second convex or concave portion.

  • the flanged portion 22 extends radially outward from the outer wall of the inner plug body 21 and seals with the upper opening of the fixing sleeve 3.
  • a sealing bead 8 is installed inside the inner plug 2.
  • the fixing sleeve 3 is cylindrical in structure and is sleeved onto the mounting segment 11. Between the inner wall of the fixing sleeve 3 and the outer wall of the lower inner plug segment 212, there is a slot 37 for inserting the bottle neck 7.

  • the claws 31 are in an open state, allowing the bottle neck 7 to be inserted into the slot 37 between the inner plug body 21 and the fixing sleeve 3.
  • the inner body 1 moves downward relative to the fixing sleeve 3, and the lower end of the inner body 1 slides along the outer surface 312 of the claws 31, causing the claws 31 to contract and engage with the first protrusion 71.
  • the fixing sleeve 3 prevents relative rotational movement between itself and the bottle neck 7 through the cooperation of the first anti-rotation recess 74 and the first anti-rotation protrusion 33, and prevents relative axial movement between the fixing sleeve 3 and the bottle neck 7 through the cooperation of the claws 31 and the first protrusion 71.
  • This design enhances anti-removal functionality and improves the stability of the bottle cap during installation.
  • the fixed sleeve 3 and the inner plug 2 are of a split-type structure, with the fixed sleeve 3 made of hard plastic material. Between the fixed sleeve 3 and the mounting segment 11, there are anti-rotation structures to prevent relative rotational movement and axial limit structures to prevent relative axial movement. Because the fixed sleeve 3 is made of hard plastic material (such as ABS plastic), when heating the bottle cap with a hair dryer or hot water, the fixed sleeve 3 is not easily deformed. This prevents the fixed sleeve 3 from being pulled out from the bottleneck 7 using heating means alone, ensuring that the bottle cap can only be removed by destroying it.
  • hard plastic material such as ABS plastic
  • the fixed sleeve 3 and the inner plug 2 can be designed as a monolithic structure.

After crimping, at least one lower outer edge of claw 31 engages into at least one of the limiting grooves 112, thereby preventing relative axial movement between fixed sleeve 3 and inner body 1.
  • This design allows claw 31 to simultaneously serve as an axial limit, which simplifies the structure.
  • the limiting grooves 112 extend longitudinally along the circumferential direction as strip shapes, with a length greater than that of claw 31 along the circumferential direction. This configuration ensures that there is no directional requirement during the assembly of fixed sleeve 3, facilitating the assembly process. Such a design simplifies the installation procedure and enhances production efficiency.
  • the lower end of flanging section 22 is equipped with a sealing portion 221 that matches the upper opening of fixed sleeve 3.

  • the cylindrical body 53 is made of ABS plastic, while the top portion 54 is made of PE (polyethylene) plastic.
  • the lower surface of the top 54 has a downward-extending sealing ring 55, which is made of soft plastic.
  • This sealing ring 55 is designed to come into close contact with a dispensing port when the bottle cap is fully tightened, providing effective sealing to prevent liquid leakage.
  • the anti-counterfeiting structure comprises a first anti-counterfeiting ring 91 on the outer cap 6 and a second anti-counterfeiting ring 92 on the outer body 4.
  • the first anti-counterfeiting ring 91 has downward-extending first anti-counterfeiting teeth (not shown in the figure), and the second anti-counterfeiting ring 92 has upward-extending second anti-counterfeiting teeth (not shown in the figure).
  • rotating the outer cap 6 causes the first anti-counterfeiting teeth to rotate.
  • the first and/or second anti-counterfeiting teeth are designed to break upon rotation, and cannot be repaired once broken or twisted, thereby achieving anti-counterfeiting purposes.
  • a bottle body for use with the above-mentioned anti-heating extraction bottle cap, as shown in Figure 14 .
  • the bottle body includes a bottle body (not shown in the figure) and a bottle neck 7 set on the bottle body, which has a bottle mouth 76.
  • the outer wall of the bottle neck 7 is equipped with first protrusions 71 and second protrusions 72 arranged at intervals from top to bottom.
  • the first locking recesses 74 are wider at the top and narrower at the bottom to facilitate smooth insertion and automatic alignment of the first locking protrusion 33 into the first locking recess 74 during sealing.
  • Figure 16 shows the assembly diagram of the anti-heating extraction bottle cap with bottle neck 7, referring to Figures 1 and 16 .
  • the lower end of installation section 11 of inner body 1 is positioned above claw 31, which remains in an open state.
  • bottle neck 7 can be inserted into slot 37 between inner plug body 21 and fixing sleeve 3.
  • the first locking protrusion 33 on fixing sleeve 3 inserts into the first locking recess 74 on the outer wall of bottle neck 7.
  • downward pressure is applied to the anti-heating extraction bottle cap.
  • Inner body 1 moves downward relative to fixing sleeve 3, and the lower end of inner body 1 slides along the outer side 312 of claw 31, causing claw 31 to contract and grip the first protrusion 71 of bottle neck 7.
  • anti-pull buckle 422 locks onto the second protrusion 72, thus securely fixing the anti-heating extraction bottle cap onto bottle neck 7.
  • the anti-heating extraction bottle cap of the present disclosure utilizes a fixed assembly with retractable claws 31 on fixing sleeve 3 and first protrusions 71 on bottle neck 7 through an expansion structure design, creating an inverted buckle inside the bottle to firmly integrate inner plug 2 and inner body 1 with the bottle. Even when heated and softened, they cannot be separated. Additionally, anti-pull buckle 422 on outer body 4 engages with second protrusion 72 on bottle neck 7, further enhancing the bonding strength between the fixed assembly and bottle neck 7.
