Description

Technical Field

[0001] This utility model relates to a perfume bottle, specifically a liquid-filled bottle structure. Background Technology

[0002] With economic development and improved living standards, people are paying more and more attention to the quality of life. To attract attention, especially women, perfume is often used. As a relatively high-end daily necessity, perfume typically has exquisite packaging. Modern perfume bottles generally consist of a bottle body, a cap, and a spray nozzle. Some bottles are composed of an inner and outer bottle to prevent evaporation and better protect the perfume inside.

[0003] Current liquid-filled bottle structures mainly suffer from two types of problems: one type uses a permanent fixed connection between the inner and outer bottles, leading to difficulties in disassembly and maintenance; the other type relies solely on the friction between the inner and outer bottles for assembly, resulting in insufficient structural stability and a stiff operating feel. Particularly at the mating points between the inner bottle and the liquid-filling components, existing designs often lack precise positioning structures, making misalignment or loosening easy during assembly. Furthermore, the traditional mating method between the inner liner sleeve and the end cap fails to achieve multiple limiting functions, easily leading to sealing failure or component detachment during long-term use. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a bottle body structure for a liquid-filled bottle, which has the advantages of convenient assembly, precise positioning, and structural stability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A liquid-filled bottle structure includes an outer bottle and an inner bottle. A nozzle assembly is installed at the upper end of the inner bottle, and a liquid-filling assembly is installed at the bottom of the inner bottle. A tail cap is fitted over the liquid-filling assembly. A middle ring is installed on the outer bottle, and an inner liner sleeve is installed on the inner side wall of the outer bottle. A ribbed limiting block is provided in the lower inner part of the inner liner sleeve, and a contact baffle is provided at the lower part of the inner bottle. A protrusion is provided on the outer wall of the tail cap. When the inner bottle and the tail cap are inserted into the bottom of the inner liner sleeve, the contact baffle of the inner bottle contacts the upper surface of the limiting block, and the protrusion of the tail cap is in close contact with the side of the limiting block.

[0007] As a further improvement, the limiting top block is integrally formed on the inner side wall of the inner liner sleeve, and there are several limiting top blocks evenly distributed on the inner side wall of the inner liner sleeve.

[0008] As a further improvement, the limiting top block has a top horizontal surface, a curved transition surface and a side vertical surface. One side of the curved transition surface is connected to the top horizontal surface and the other side is connected to the side vertical surface. The top horizontal surface is used to contact the contact baffle at the bottom of the inner bottle. The elasticity of the inner sleeve material is used to make the protrusion of the tail cap fit tightly against the side vertical surface and be held in place by the curved transition surface.

[0009] As a further improvement, the curved transition surface includes an upper arc-shaped surface, a middle inclined surface, and a lower inclined surface connected in sequence. The middle inclined surface is inclined toward the center of the inner liner sleeve, and the lower inclined surface is inclined toward the side wall of the inner liner sleeve, so that the lower inclined surface engages with the protrusion of the tail cap.

[0010] As a further improvement, the upper part of the inner liner sleeve is provided with a clamping member that protrudes in the width direction and fits against the outer surface of the inner bottle.

[0011] As a further improvement, the bottom surface of the inner sleeve is provided with an elastic pad that contacts the bottom of the outer casing.

[0012] As a further improvement, the bottom surface of the inner liner sleeve is provided with an opening groove.

[0013] As a further improvement, the outer wall of the inner liner sleeve is provided with a reinforcing strip extending along the length of the inner liner sleeve, and the reinforcing strip is fitted and connected to the inner wall of the outer bottle.

[0014] As a further improvement, the protrusion is integrally formed on the tail cap and surrounds the circumference of the tail cap.

[0015] As a further improvement, the contact surface at the bottom of the inner bottle is arc-shaped.

[0016] This utility model has the following beneficial technical effects:

[0017] By engaging the contact surface of the inner bottle and the tail cap when they are inserted into the bottom of the inner liner sleeve with the limiting block, and by tightly fitting the protrusion with the side of the limiting block, multiple positioning and stable engagement are achieved, improving the operating feel. It has the advantages of convenient assembly, accurate positioning and stable structure. Attached Figure Description

[0029] like Figure 1-6 As shown, a liquid-filled bottle structure includes an outer bottle 1 and an inner bottle 3. A nozzle assembly 6 is attached to the upper end of the inner bottle 3, and a liquid-filling assembly 10 is attached to the bottom of the inner bottle 3. A tail cap 8 is fitted over the liquid-filling assembly 10. A middle ring 4 is installed on the outer bottle 3. An inner liner sleeve 2 is fitted to the inner wall of the outer bottle 1. Several evenly distributed limiting top blocks 9 are integrally formed in the lower inner part of the inner liner sleeve 2. A contact baffle 7 is provided at the lower part of the inner bottle 3, and a protrusion 14 is provided on the outer wall of the tail cap 8. When the inner bottle 3 and the tail cap 8 are inserted into the bottom of the inner liner sleeve 2, the contact baffle 11 of the inner bottle 3 contacts the upper surface of the limiting top blocks 9, and the protrusion 14 of the tail cap 8 is in close contact with the side of the limiting top blocks 9. Both the nozzle assembly 6 and the liquid-filling assembly 10 adopt existing technology structures, and a dust cover can also be fitted onto the nozzle assembly.

[0030] The inner liner sleeve 2 refers to the guide structure installed inside the outer bottle. Specifically, it can be an injection-molded cylindrical component, with a limiting block on its inner wall for vertical positioning and limiting of the inner bottle. The contact surface refers to the annular flange extending outward from the lower part of the inner bottle, which can be manufactured using an in-mold molding process. It is used to contact the upper surface of the limiting block to form an axial limit. The protrusion refers to the annular protrusion extending circumferentially from the outer wall of the tail cap. Typically, a single ring is provided to meet installation requirements. Specifically, it can be an integrally molded structure with the tail cap, achieving radial positioning by fitting against the side of the limiting block. A portion of the middle ring is embedded in the inner wall of the outer bottle, while another portion is exposed on the outside of the outer bottle. This serves both an aesthetic purpose and limits the upward movement of the inner liner sleeve.

[0031] Specifically, during assembly, the inner liner sleeve 2 is first assembled and secured to the outer bottle 1. The inner bottle 3, carrying the tail cap 8, moves axially along the inner liner sleeve 2. When the contact surface 7 of the inner bottle 3 contacts the upper surface of the limiting block 9, the inner bottle 3 is prevented from moving further downward. At this time, the protrusion 14 of the tail cap 8 is blocked by the side wall of the limiting block 9, forming a radial constraint. The limiting block at the bottom of the inner liner sleeve achieves bidirectional positioning of the inner bottle and the tail cap in both the axial and radial directions through the combination of the upper and lower surfaces and the side surfaces.

[0032] This solution forms a multi-directional constraint through the limiting top block 9 inside the inner sleeve 2, and maintains structural stability through the dual limiting of the contact baffle 7 and the protrusion 14.

[0033] Through the above technical solution, this application achieves rapid and accurate positioning of the inner and outer bottles, reducing operational effort while ensuring assembly stability. The cooperation between the limiting top block and the contact stop effectively prevents axial movement of the inner bottle, and the fit between the protrusion and the side of the limiting top block avoids radial displacement.

[0034] The limiting block 9 has a top horizontal surface 11, a curved transition surface 12, and a side vertical surface 13. One side of the curved transition surface 12 is connected to the top horizontal surface 11, and the other side is connected to the side vertical surface 13. The top horizontal surface 11 is used to contact the contact baffle 7 at the bottom of the inner bottle 3. The protrusion 14 of the tail cap 8 is tightly attached to the side vertical surface 13 and is held in place by the curved transition surface 12. The elasticity of the inner sleeve material allows the tail cap to fit tightly against the side vertical surface. The top horizontal surface can be a horizontal plane, used to contact and abut against the contact baffle at the bottom of the inner bottle, forming a limiting effect.

[0035] The curved transition surface 12 includes an upper arc-shaped surface 121, a middle inclined surface 122, and a lower inclined surface 123 connected in sequence. The middle inclined surface 122 is inclined towards the center of the inner liner sleeve 2, and the lower inclined surface 123 is inclined towards the side wall of the inner liner sleeve 2, so that the lower inclined surface 123 engages with the protrusion 14 of the tail cap 8. The arc-shaped surface 121 and the middle inclined surface 122 help the protrusion on the tail cap slide more smoothly from top to bottom, and after the protrusion slides to the side vertical surface, its upward direction is blocked by the lower inclined surface 123, thus forming stability.

[0036] Specifically, when the inner bottle 3 is inserted into the inner liner sleeve 2, the contact surface 7 at the bottom of the inner bottle 3 contacts the top horizontal surface 11, achieving axial positioning. During installation, the protrusion 14 of the tail cap 8 slides along the curved transition surface 12 until it is completely fitted with the side vertical surface 13. At this point, the curved transition surface 12, through its curved shape, acts as a locking mechanism for the protrusion 14, fixing the tail cap 8 both axially and circumferentially. This structure, through multi-directional positioning, ensures precise and stable assembly of the inner bottle and tail cap. This application solves the problems of inaccurate positioning and weak fixation caused by the single positioning structure in existing liquid-filled bottle assembly. By using a multi-faceted mating structure, it achieves rapid alignment and reliable fixation of the inner bottle and tail cap, avoiding sealing failure or increased operating resistance caused by component misalignment.

[0037] The upper part of the inner liner sleeve 2 is provided with a clamping member 15 protruding in the width direction. The clamping member 15 fits against the outer surface of the inner bottle 3, and multiple clamping members are formed along the circumference of the inner liner sleeve 2.

[0038] The clamping element protruding along the width direction refers to an elastic protrusion extending outward from the upper part of the inner liner sleeve. Specifically, it can be implemented using a sheet-like component with an arc-shaped cross-section, which forms contact with the outer surface of the inner bottle through pressure generated by its own deformation. "Fitting" refers to a gapless contact state between the clamping element 15 and the outer surface of the inner bottle 3. This can be achieved by adjusting the curvature or thickness of the clamping element, causing it to elastically deform and apply radial pressure during assembly.

[0039] Specifically, when the inner bottle 3 is inserted into the inner liner sleeve 2, the clamping member 15 undergoes elastic deformation due to the compression of the outer wall of the inner bottle 3. The reverse force generated by the deformation causes the clamping member to continuously press against the surface of the inner bottle. Since the clamping member protrudes along the width direction of the inner liner sleeve, its coverage area increases, which can form a uniformly distributed constraint force in the circumference of the inner bottle, thereby restricting the displacement of the inner bottle in the vertical direction.

[0040] This solution utilizes the elastic fit of the clamping components to avoid the difficulties in disassembly and assembly caused by rigid connections, while also improving the stability of the inner bottle through multi-point uniform pressure application. At the same time, it can achieve reliable positioning without the need for additional fixing structures.

[0041] Through the above technical solution, this application can form a detachable elastic fixing structure between the inner bottle and the outer bottle, effectively preventing the inner bottle from shaking or falling off during transportation or use, while simplifying the assembly steps and improving the handling feel.

[0042] The bottom surface of the inner liner sleeve is provided with an elastic pad, which contacts the bottom of the outer shell and serves to eliminate the manufacturing gap between the inner liner sleeve and the bottom of the outer shell.

[0043] The bottom surface of the inner liner sleeve 2 is provided with an opening groove 17. Specifically, when the inner bottle 3 and the tail cap 8 are inserted into the bottom of the inner liner sleeve 2, the presence of the opening groove 17 allows the bottom of the inner liner sleeve to undergo slight deformation when squeezed by the tail cap, thereby reducing assembly resistance. The size and position of the opening groove can be adjusted according to the thickness and material properties of the inner liner sleeve. For example, a rectangular groove or an annular groove can be provided in the central area of ​​the bottom surface, so that the tail cap and the inner liner sleeve can achieve a tight fit through the elastic buffer of the opening groove when they come into contact.

[0044] The outer wall of the inner liner sleeve 2 is provided with a reinforcing strip 18 extending along the length of the inner liner sleeve, and the reinforcing strip 18 is fitted and connected to the inner wall of the outer bottle 1.

[0045] The reinforcing strip can be formed into continuous or intermittent raised strips using injection molding. Its function is to increase the contact area and improve the connection strength between the inner liner sleeve and the outer bottle. The fitted connection refers to the surface contact between the outer surface of the reinforcing strip and the inner wall of the outer bottle, which can be achieved using interference fit or snap-fit ​​structure. Its function is to enhance the stability of the inner and outer bottle assembly through mechanical interlocking.

[0046] This structure allows the reinforcing strips to disperse stress and prevent relative sliding between the inner liner sleeve and the outer bottle when the inner and outer bottles are subjected to external forces.

[0047] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
