Description

A vessel covered with silver inside and out Technical Field

[0001] This utility model relates to the field of vessel and container technology, specifically to a vessel with silver cladding inside and out. Background Technology

[0002] Currently, most silverware (such as silver bowls and cups) is made of pure silver, which has the following technical drawbacks: excessive weight: pure silver has a high density (10.49 g / cm³). 3 This significantly increases the overall weight of the container, making it tiring to hold and especially unsuitable for prolonged use by children or the elderly. Rapid heat dissipation: Silver has a thermal conductivity as high as 429 W / m·K, causing heat to be rapidly conducted to the outer wall when hot drinks are contained, easily burning the user's hands and making it difficult to maintain a suitable drinking temperature. To address these issues, existing technologies have attempted various improvements, but all have significant shortcomings: Encasing the silver inner liner in melamine resin (such as patent CN205338430U) provides insulation and improves durability, but the melamine injection molding process is complex, and the silver inner liner still needs to be cast entirely, failing to substantially reduce the amount of silver used; Partial silver plating technology: such as silver plating on the inner wall of ceramic containers (patent document CN20655172U), while reducing silver consumption, is prone to peeling due to thermal expansion and contraction, and cannot achieve a complete seal, posing hygiene risks. Mechanical structure optimization: A spring-loaded cover (patent CN27443236U) is used to alleviate the difficulty of opening the cover, but this does not solve the inherent defects of silver material and increases the complexity and cost of the structure. Summary of the Invention

[0003] In view of this, this utility model proposes a vessel with silver coating inside and out, so as to reduce weight while improving heat preservation effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vessel with silver cladding inside and out includes a silver base having a receiving cavity; an inner layer attached to the inner surface of the receiving cavity, the inner layer comprising a heat-retaining material; and a silver liner fixedly covering the upper surface of the inner layer, such that the inner layer is sandwiched between the base and the silver liner.

[0006] To better achieve the above technical solution, the inner interlayer may optionally include a porous framework and paraffin or fatty acid filling the pores of the porous framework.

[0007] Optionally, the pore diameter in the porous skeleton is 3mm-5mm.

[0008] Optionally, the porous skeleton is made of rice husk or palm shell.

[0009] Optionally, the outer edge of the inner interlayer extends outward from the accommodating cavity to form a first flange, which wraps around the upper edge of the base.

[0010] Optionally, the outer edge of the silver bladder extends outward from the receiving cavity to form a second flange, the second flange wrapping around the first flange and connecting with the outer wall of the base.

[0011] Optionally, the inner interlayer is made of heat-insulating plastic, ceramic, or stainless steel.

[0012] Optionally, the vessel is a bowl, basin, or cup.

[0013] The beneficial effects of this utility model are:

[0014] Compared to traditional pure silver vessels, this utility model's silver-coated vessel solves the problems of heavy weight and poor heat retention by designing an interlayer, while significantly improving the vessel's heat retention effect while maintaining the safety of silver contact.

[0019] Base 10, inner layer 20, porous skeleton 21, paraffin or fatty acid 22, first flange 23, silver liner 30, second flange 31. Detailed Implementation

[0020] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0021] Please refer to Figures 1 to 3. This utility model embodiment discloses a vessel with silver cladding inside and out, including: a base 10, an inner layer 20, and a silver liner 30.

[0022] As shown in Figure 1, the base 10 is made of silver and has a recessed cavity. When the vessel is a bowl, basin, or cup, the recessed cavity is a placement cavity. The inner layer 20 is attached to the inner surface of the recessed cavity. The inner layer 20 includes a heat-storing material. Specifically, the inner layer 20 is tightly attached to the inner surface of the recessed cavity. The silver liner 30 is fixedly covered on the upper surface of the inner layer 20, so that the inner layer 20 is sandwiched between the base 10 and the silver liner 30, forming a vessel with the inner layer 20 in the middle and silver material on both sides, which is silver-clad inside and out.

[0023] This utility model discloses a vessel with silver cladding inside and out. The inner layer 20 replaces the original space of the silver material, which can reduce the weight of the vessel. At the same time, the inner layer 20, which uses heat-storing material, can quickly absorb the heat of the object in the cavity, so that the heat of the object in the cavity and the inner layer 20 can quickly achieve thermal equilibrium. In addition, the heat-storing material has a heat preservation effect, and its heat absorption and release properties extend the heat preservation time of the vessel.

[0024] In an optional embodiment of this invention, the inner interlayer 20 includes a porous skeleton 21 and paraffin or fatty acid 22 filling the pores of the porous skeleton 21. The pore size of the porous skeleton 21 is 3mm-5mm, and the material of the porous skeleton 21 is rice husk or palm shell. The porous skeleton 21 is formed after carbonization of rice husk or palm shell. After absorbing paraffin or fatty acid 22, the porous skeleton 21 forms a solid-solid phase change composite material. The thermal conductivity of this material can be increased to 1.5-2W / m·K. At the same time, the inner interlayer 20 is easy to shape and can be easily attached to the inner surface of the accommodating cavity. Using this inner interlayer 20 can significantly improve the heat preservation effect of the vessel.

[0025] In an embodiment of this utility model, the outer edge of the inner interlayer 20 extends outward from the accommodating cavity to form a first flange 23, which wraps around the upper edge of the base 10. The outer edge of the silver liner 30 extends outward from the accommodating cavity to form a second flange 31, which wraps around the first flange 23 and is in contact with the outer wall of the base 10. The first flange 23 of the inner interlayer 20 and the second flange 31 of the silver liner 30 form a double-wrapping structure, which enhances the bonding strength between the components through physical anchoring. In addition, the flange structure increases the contact area, thereby increasing the connection strength between the silver liner 30 and the base 10 by 3 times, preventing delamination caused by temperature changes or external forces.

[0026] In other optional embodiments of this utility model, the inner interlayer 20 is made of heat-insulating plastic, ceramic, or stainless steel.

[0027] The technical solution of this utility model has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of this utility model. Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
