Description

Technical Field

[0001] This utility model belongs to the field of thermos bottle technology, specifically relating to a thermos bottle made of double-layer high-temperature resistant polyester material. Background Technology

[0002] Most existing polyester bottles adopt a single-layer structure, which is lightweight and easy to carry. However, due to limitations in thickness and material, their overall structural strength is poor and they are prone to deformation. At the same time, the single-layer structure results in poor heat preservation. In order to improve their structural strength and heat preservation performance, the bottle body is usually thickened, but this also leads to an increase in material costs.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a polyester bottle for easy sealing and storage of pesticides [202221053152.4]. The bottle body has a handle movably connected to one side, and a cap movably connected to the top. The bottle body includes an outer body, a neck fixedly connected to the top of the outer body, a fixing plate fixedly connected to the top of the neck, a bottle mouth fixedly connected to the top of the fixing plate, and a threaded connection to the outer side of the bottle mouth. An insulation cavity is formed inside the outer body, and the bottom of the cap is movably connected to the top of the bottle body via internal and external threads.

[0004] The above solution has solved the problem of insufficient structural strength of polyester bottles to some extent, but it still has many shortcomings, such as poor overall thermal insulation performance. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a well-designed, high-temperature resistant double-layered thermos made of polyester material with good heat preservation performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a double-layer high-temperature resistant polyester thermos, comprising an outer bottle body and an inner bottle body made of polyester material, the bottom of the outer bottle body being sealed by an insulation base, the insulation base having a support component extending between the outer bottle body and the inner bottle body, an insulation cap being provided at the bottle mouth of the outer bottle body and the inner bottle body, a sealing component being provided between the support component and the outer bottle body and the inner bottle body, and aerogel being filled between the outer bottle body and the inner bottle body.

[0007] In the above-mentioned double-layer high-temperature resistant polyester thermos, the outer bottle and the inner bottle each have a cylindrical body and a bottleneck that is integrally formed with the bottle body and extends upwards, with a gap of 1.0-2.0mm between the outer bottle and the inner bottle.

[0008] In the above-mentioned double-layer high-temperature resistant polyester thermos, the outer side of the heat preservation base is provided with a fixed step surface that fits and presses against the lower end of the outer bottle body. The fixed step surface has several recesses arranged in a centrally symmetrical manner distributed along the circumference. The lower end of the outer bottle body is heat-pressed into the recesses.

[0009] In the above-mentioned double-layer high-temperature resistant polyester thermos, the support assembly includes a support plate that is centrally symmetrically installed on the upper end of the thermos base. The support plate has a horizontal plate that presses against the lower end of the inner bottle and a vertical plate that is vertically set and fixed between the inner bottle and the outer bottle.

[0010] In the aforementioned double-layer high-temperature resistant polyester thermos, vertical plates are connected by support rings arranged in a vertical direction, and aerogel is filled between the support rings and the vertical plates.

[0011] In the above-mentioned double-layer high-temperature resistant polyester thermos, a sealing sleeve is provided between the bottle mouth of the outer bottle and the inner bottle. Anti-slip stripes are provided on the side of the sealing sleeve opposite to the outer bottle and the inner bottle. Anti-slip ribs are provided at the bottle mouth of the outer bottle and the inner bottle to press against the anti-slip stripes.

[0012] In the aforementioned double-layer high-temperature resistant polyester thermos, the thermos cap and the sealing sleeve are threaded together and a sealing ring is provided between them.

[0013] In the aforementioned double-layer high-temperature resistant polyester thermos, the sealing component includes sealing strips disposed at the bottle mouth and bottom gaps of the outer bottle body and the inner bottle body.

[0014] In the aforementioned double-layered high-temperature resistant polyester thermos, an indicator scale is provided on the outer bottle body.

[0015] In the aforementioned double-layer high-temperature resistant polyester thermos, a counterweight is provided at the lower end of the insulation base.

[0016] Compared with existing technologies, the advantages of this utility model are as follows: the space between the outer bottle and the inner bottle is filled with aerogel and fixed by the support component, which ensures the heat preservation effect of the polyester bottle itself; the support component provides good support for the inner bottle, which can ensure the structural strength of the inner and outer bottles; the sealing component completely seals the gap between the inner and outer bottles, ensuring the airtightness of the cavity and maintaining its long-term heat preservation effect.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-4 As shown, a double-layered high-temperature resistant polyester thermos includes an outer bottle body 1 and an inner bottle body 2, both made of polyester. The overall structure is lightweight. The bottom of the outer bottle body 1 is sealed by an insulating base 3. The insulating base 3 has a support component 4 extending between the outer bottle body 1 and the inner bottle body 2. Insulating caps 5 are provided at the mouths of the outer bottle body 1 and the inner bottle body 2. This assembly structure primarily maintains the relative structural stability of the outer bottle body 1 and the inner bottle body 2. A sealing component 6 is provided between the support component 4 and the outer bottle body 1 and the inner bottle body 2. Aerogel 7 is filled between the outer bottle body 1 and the inner bottle body 2. The aerogel 7, combined with the support component 4, maintains the overall structural strength and heat insulation performance of the thermos.

[0024] Specifically, the thermos bottle has a slender shape, with the outer bottle body 1 and the inner bottle body 2 having a cylindrical body and a neck that is integrally formed with the body and extends upward. There is a gap of 1.0-2.0mm between the outer bottle body 1 and the inner bottle body 2, which provides a certain filling space for the aerogel 7.

[0025] Specifically, the heat-insulating base 3 has a fixed step surface 31 on its outer periphery that fits and presses against the lower end of the outer bottle 1. The fixed step surface 31 has several centrally symmetrically arranged recesses 32 distributed circumferentially. The lower end of the outer bottle 1 is heat-pressed into place with the recesses 32. The bottom of the outer bottle 1 is detachable, facilitating the assembly of the internal support assembly 4 and the inner bottle 2.

[0026] Furthermore, unlike conventional support frame structures, the support component 4 in this embodiment includes a support plate 41 centrally symmetrically mounted on the upper end of the insulation base 3. The support plate 41 has a horizontal plate 42 pressing against the lower end of the inner bottle 2 and a vertical plate 43 vertically arranged and fixed between the inner bottle 2 and the outer bottle 1. The support plate 41 mainly supports the inner bottle 2, while the vertical plate 43 mainly maintains the stability of the gap.

[0027] In addition, vertically arranged support rings 44 are connected between the vertical plates 43, and aerogel 7 is filled between the support rings 44 and the vertical plates 43. The vertical plates 43 further strengthen the support plate 41, ensuring the stability of the central structure of the support plate 41. The support rings 44 also axially limit the aerogel 7. The combined cavity structure provides good protection for the block aerogel 7.

[0028] Meanwhile, a sealing sleeve 8 is provided between the bottle openings of the outer bottle 1 and the inner bottle 2. Anti-slip stripes 81 are provided on the side of the sealing sleeve 8 opposite to the outer bottle 1 and the inner bottle 2. Anti-slip ribs 82 are provided at the bottle openings of the outer bottle 1 and the inner bottle 2, pressing against the anti-slip stripes 81. The sealing sleeve 8 is usually made of a rigid material, and its gaps are completely filled by the sealing component 6.

[0029] As can be seen, the heat preservation cap 5 is threadedly connected to the sealing sleeve 8 and a sealing ring 83 is provided between them. The sealing ring 83 is made of silicone material, which ensures the sealing and waterproof effect at the bottle mouth after being pressed and fixed.

[0030] Clearly, the sealing assembly 6 includes a sealing strip 61 disposed at the bottle mouth and bottom gaps of the outer bottle body 1 and the inner bottle body 2. The sealing strip 61 is pressed and fixed between the bottle body 1 and the inner bottle body 2 and serves as an adhesive.

[0031] Preferably, the outer bottle 1 is provided with an indicator scale 11, which is used to determine the fluid content inside the inner bottle 2, thus avoiding errors in determining the internal capacity caused by the sandwich structure.

[0032] Obviously, a counterweight 12 is provided at the lower end of the heat preservation base 3. The thermos bottle is placed vertically, and the bottom counterweight 12 maintains its structural stability.

[0033] In summary, the principle of this embodiment is as follows: the outer bottle 1 and the inner bottle 2 are combined, with aerogel 7 filling the space between them and the structural stability maintained by the support component 4. The heat preservation base 3 and the heat preservation cover 5 achieve interlayer sealing, thereby maintaining the overall heat preservation effect of the thermos bottle.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0035] Although this document frequently uses terms such as outer bottle 1, indicator scale 11, counterweight 12, inner bottle 2, insulation base 3, fixed step surface 31, recess 32, support assembly 4, support plate 41, horizontal plate 42, vertical plate 43, support ring 44, insulation cover 5, sealing assembly 6, sealing strip 61, aerogel 7, sealing sleeve 8, anti-slip stripe 81, anti-slip rib 82, and sealing ring 83, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
