Description

Technical Field

[0001] This utility model relates to the field of cup auxiliary components, specifically to a cup with a decorative outer shell. Background Technology

[0002] A water cup, also known as a mug, is a common drinking utensil. With changing and increasing consumer demands, mugs have become increasingly diverse in design and production, boasting a wide variety of styles and structural forms. Currently, in the design process of water cups, to make them look aesthetically pleasing and high-end, a decorative silver shell with patterns is often added to the outside. However, if the silver shell is directly applied to the outside of the cup, it is prone to deformation due to the softness of the silver material during use. Therefore, a supporting inner shell made of stainless steel is usually added inside the silver shell to prevent deformation and damage during use, thus extending the lifespan of the water cup.

[0003] In the existing technology, specifically in the production process of cups with decorative shells, the supporting inner shell and the decorative shell are usually combined together by pressure expansion to process the entire decorative shell. Then, the inner liner of the cup is fixed to the inner circumference of the decorative shell to process the entire cup body, thereby achieving a stable combination of the silver decorative shell and the stainless steel supporting inner shell on the outside of the cup.

[0004] However, the above manufacturing method has at least the following defects in actual production: 1. When the inner shell is compressed with the outer shell, the bottom of the outer shell is easily pierced and damaged by the bottom of the inner shell due to the low strength of the bottom of the outer shell, resulting in a high scrap rate of the outer shell; 2. The inner liner is usually combined with the outer shell by a straight insertion method. Since the top joint of the inner liner and the outer shell is not treated, the seal at this position is not tight. Water can easily enter the space between the outer shell and the inner panel through this position. Over time, not only will an odor be produced, but the outer shell will also rust due to water immersion and produce waste. Utility Model Content

[0005] The purpose of this invention is to provide a cup with a decorative outer shell in order to solve the above-mentioned problems, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a cup with a decorative outer shell, comprising an inner liner body, a supporting inner shell, and a decorative outer shell body. The decorative outer shell body is fixed to the periphery of the supporting inner shell body. The inner bottom surface of the decorative outer shell body is coaxially filled with a reinforcing bottom pad in a sliding fit manner, and the bottom end of the supporting inner shell body is pressed against the top surface of the reinforcing bottom pad body around the periphery. The top periphery of the inner liner body is pre-integrated with a full ring of anti-loosening flanges, and the inner liner body is tightly connected to the supporting inner shell through the pre-integrated anti-loosening flanges.

[0007] Preferably, the top edges of both the supporting inner shell and the decorative outer shell are sealing flanges that are pressed against the top periphery of the anti-loosening flange.

[0008] Preferably, the junction of the sealing flange and the anti-loosening flange is filled with a full circle of insulating sealing filler around the perimeter.

[0009] Preferably, the insulating sealant is a food-grade silicone sealant with a coating thickness of not less than 0.5 mm.

[0010] Preferably, the decorative outer shell is a silver cylinder with an open top and a closed bottom, and the supporting inner shell is a stainless steel cylinder with open top and bottom.

[0011] Preferably, the inner liner body is a double-layer stainless steel heat-insulating inner liner with a vacuum heat insulation cavity, and the anti-loosening flange is integrally formed with the inner liner body.

[0012] Preferably, the outer periphery of the decorative outer shell is provided with decorative patterns, and the decorative patterns are formed by the expansion and pressing of the inner supporting shell to the outer decorative outer shell.

[0013] Preferably, the outer surface of the supporting inner shell is roughened by sandblasting, and the fit tolerance between the supporting inner shell and the decorative outer shell is controlled within H7 / h6.

[0014] In the production of a cup with a decorative outer shell, the reinforced bottom pad is coaxially and horizontally filled with a sliding fit at the bottom of the decorative outer shell. This prevents the supporting inner shell from piercing and damaging the bottom of the decorative outer shell by contacting the reinforced bottom pad, thus enhancing the load-bearing capacity of the bottom of the decorative outer shell and improving the yield rate. Simultaneously, since the inner liner is securely connected to the supporting inner shell via a pre-set anti-loosening flange, there is no need to add an additional ring fastener to the outer surface of the inner liner, facilitating the connection between the inner liner and the supporting inner shell. The supporting inner shell is fixed in place, and since the top edges of both the supporting inner shell and the decorative outer shell are sealing flanges that are pressed against the top periphery of the anti-loosening flange, and the joint position of the sealing flange and the anti-loosening flange is filled with a full circle of insulating sealing material, the joint position of the inner liner body with the supporting inner shell and the decorative outer shell can be insulated and sealed, preventing water from entering the gap between the inner liner body and the supporting inner shell through this position. This prevents the generation of odors and also prevents the inner liner body and the supporting inner shell from rusting and producing waste debris due to water immersion, thus avoiding galvanic corrosion at the source.

[0015] The beneficial effects are as follows: 1. The present invention has a reinforced bottom pad that is coaxially filled and flat in the inner bottom of the decorative shell in a sliding fit manner. By supporting the bottom end of the inner shell against the reinforced bottom pad, it can prevent the supporting inner shell from piercing and damaging the bottom of the decorative shell, thereby enhancing the load-bearing capacity of the bottom of the decorative shell and improving the yield rate. 2. The inner liner body is fastened to the supporting inner shell by the pre-set anti-loosening flange on the periphery, eliminating the need to install additional ring fasteners on the periphery of the inner liner body, which facilitates the combination and fixation of the inner liner body and the supporting inner shell. 3. The top edges of both the supporting inner shell and the decorative outer shell are sealed flanges that are pressed against the top periphery of the anti-loosening flange. The joint between the sealing flange and the anti-loosening flange is filled with a full circle of insulating sealing material. This provides insulation and sealing to the joint between the inner liner and the supporting inner shell and the decorative outer shell, preventing water from entering the gap between the inner liner and the supporting inner shell. This prevents the generation of odors and avoids the inner liner and supporting inner shell from rusting and producing debris due to water immersion, thus preventing galvanic corrosion at its source.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] See Figure 1 As shown, this utility model provides a cup with a decorative outer shell, including an inner liner body 1, a supporting inner shell 3, and a decorative outer shell body 2. The decorative outer shell body 2 is fixed to the periphery of the supporting inner shell 3. The inner bottom surface of the decorative outer shell body 2 is coaxially filled with a reinforcing bottom pad 5 in a sliding fit. The bottom end of the supporting inner shell 3 is pressed against the top periphery of the reinforcing bottom pad 5. The top periphery of the inner liner body 1 is pre-integrated with a full circle of anti-loosening flanges 101. The inner liner body 1 is tightly connected to the supporting inner shell 3 through the pre-integrated anti-loosening flanges 101. The reason for this design is that the inner liner body 1 is tightly connected to the supporting inner shell 3 through the pre-integrated anti-loosening flanges 101, eliminating the need to add an additional ring fixing component to the periphery of the inner liner body 1. At the same time, the way the bottom end of the supporting inner shell 3 abuts against the reinforcing bottom pad 5 can prevent the supporting inner shell 3 from piercing and damaging the bottom of the decorative outer shell body 2, thereby enhancing the load-bearing capacity of the bottom of the decorative outer shell body 2 and improving the yield rate.

[0021] See Figures 1-2As shown, the following optimizations were made to the supporting inner shell 3, the decorative outer shell 2, and the inner liner body 1. Specifically, for the supporting inner shell 3 and the decorative outer shell 2, the top edges of the supporting inner shell 3 and the decorative outer shell 2 are both sealing flanges 6 that are pressed against the top periphery of the anti-loosening flange 101. The joint position of the sealing flange 6 and the anti-loosening flange 101 is filled and covered with a whole ring of insulating sealing filler 7 around the periphery. The purpose of this setting is to provide insulation and sealing treatment at the joint position of the inner liner body 1 with the supporting inner shell 3 and the decorative outer shell 2, preventing water from entering the gap between the inner liner body 1 and the supporting inner shell 3 through this position. This not only prevents the generation of odors, but also prevents the inner liner body 1 and the supporting inner shell 3 from rusting and generating waste debris due to water immersion, thus avoiding galvanic corrosion at the source. Optionally, the insulating sealant 7 is made of food-grade silicone sealant with a coating thickness of not less than 0.5 mm. This ensures that the insulating sealant 7 can completely and stably fill the gaps at the joint between the inner liner body 1, the supporting inner shell 3, and the decorative outer shell 2, ensuring a good water-proof and insulating seal, cutting off the electrochemical pathway for galvanic corrosion, and preventing electrolyte (water, beverages) from seeping into the contact interface, thus avoiding galvanic corrosion at its source. Even more optionally, the decorative outer shell 2 is a silver cylinder with an open top and a closed bottom, and the supporting inner shell 3 is a stainless steel cylinder with open top and bottom. This design ensures that the decorative outer shell 2 and the supporting inner shell 3 have good strength and aesthetics when combined, and also allows the decorative outer shell 2 to be stably fitted to the outside of the inner liner body 1 with the help of the supporting inner shell 3.

[0022] See Figures 1-2 As shown, specifically regarding the inner liner body 1, the inner liner body 1 is a double-layer stainless steel insulated inner liner with a vacuum insulation cavity, and the anti-loosening flange 101 is integrally formed with the inner liner body 1, so that there is no need to install additional ring fasteners on the outside of the inner liner body 1, which facilitates the combination and fixation of the inner liner body 1 and the supporting inner shell 3. At the same time, since the inner liner body 1 has good heat insulation capabilities, it can avoid heat conduction to the decorative outer shell 2 and the supporting inner shell 3, and prevent structural deformation, connection cracking and sealing failure of the insulating sealing filler 7 caused by the difference in thermal expansion between the decorative outer shell 2 and the supporting inner shell 3. Optionally, the outer periphery of the decorative outer shell 2 is provided with decorative patterns 4, and the decorative patterns 4 are formed by the expansion and pressing of the inner supporting inner shell 3 towards the outer decorative outer shell 2. Preferably, the decorative patterns 4 can be in the form of floral patterns, text patterns or patterns, so as to further enhance the aesthetics of the outer periphery of the decorative outer shell 2. It should be noted that the decorative patterns 4 are ultimately located on the outer surface of the decorative outer shell 2, and the supporting inner shell 3 is completely wrapped by the decorative outer shell 2.

[0023] See Figures 1-2As shown, optionally, the outer surface of the supporting inner shell 3 is roughened by sandblasting, and the fit tolerance between the supporting inner shell 3 and the decorative outer shell 2 is controlled at H7 / h6 (clearance fit based on hole basis). The consideration for this setting is that, firstly, by roughening the outer surface through sandblasting, the bonding area between the supporting inner shell 3 and the decorative outer shell 2 can be increased, and the structural stability after the two are bonded can be significantly improved by the expansion sleeve process. At the same time, by controlling the fit tolerance between the supporting inner shell 3 and the decorative outer shell 2 within the aforementioned tolerance, the assemblability during expansion sleeve can be guaranteed, and a small buffer space can be reserved for thermal expansion.

[0024] With the above structure, in actual production, a reinforcing bottom pad 5 is coaxially and horizontally filled in the inner bottom of the decorative outer shell 2 in a sliding fit manner. This prevents the supporting inner shell 3 from puncturing and damaging the bottom of the decorative outer shell 2 by the supporting inner shell 3 against the reinforcing bottom pad 5, thus enhancing the load-bearing capacity of the bottom of the decorative outer shell 2 and improving the yield rate. Simultaneously, since the inner liner body 1 is tightly connected to the supporting inner shell 3 via a pre-set anti-loosening flange 101, there is no need to add an additional ring fastener to the outer surface of the inner liner body 1, facilitating the connection between the inner liner body 1 and the supporting inner shell 3. The combination is fixed, and since the top edges of the supporting inner shell 3 and the decorative outer shell 2 are both sealed flanges 6 pressed against the top periphery of the anti-loosening flange 101, and the joint position of the sealing flange 6 and the anti-loosening flange 101 is filled with a whole ring of insulating sealing filler 7, the joint position of the inner liner body 1 with the supporting inner shell 3 and the decorative outer shell 2 can be insulated and sealed, preventing water from entering the gap between the inner liner body 1 and the supporting inner shell 3 through this position. This not only prevents the generation of odor, but also prevents the inner liner body 1 and the supporting inner shell 3 from being immersed in water and rusting, thus preventing galvanic corrosion from the root.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
