Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic cup technology, specifically a plastic cup with an anti-scalding partition structure. Background Technology
[0002] Plastic cups are widely used in daily life due to their advantages such as being lightweight, durable, and inexpensive. However, when traditional single-layer plastic cups are filled with hot water, the cup walls conduct heat rapidly, causing the outer surface temperature to become too high and easily scalding the user.
[0003] Currently, most anti-scalding plastic cups on the market adopt a double-layer structure design, achieving heat insulation by setting an air gap between the inner and outer cup bodies. However, this fixed double-layer structure has a significant drawback: when either layer (inner or outer cup body) breaks due to drops, aging, or long-term use, the entire cup becomes unusable, forcing users to replace it with a completely new cup, resulting in resource waste. Therefore, we propose a plastic cup with an anti-scalding air gap structure. Utility Model Content

Please refer to [link / reference]. Figures 1-4 The plastic cup provided in this embodiment has a heat-resistant partition structure, and its main body includes a plastic cup assembly 100.
[0027] The plastic cup assembly 100 includes an outer cup body 110 and an inner cup body 120 disposed inside the outer cup body 110. A heat-insulating cavity is formed between the outer cup body 110 and the inner cup body 120. A first external thread 111 is provided on the upper side of the outer wall of the outer cup body 110. A heat dissipation hole 112 is provided at the bottom of the outer cup body 110 located in the heat-insulating cavity. A rubber stopper 113 is provided in the heat dissipation hole 112. An outwardly turned connecting part 121 is provided on the upper side of the outer wall of the inner cup body 120. An internal thread is provided on the inner wall of the connecting part 121. The connecting part 121 is threadedly connected to the outer cup body 110. A cup lid 122 is provided on the inner cup body 120. Preferably, in this embodiment, a circular base 114 is provided on the outer bottom of the outer cup body 110. A through hole 115 is provided on the circular base 114, which is adapted to the size of the rubber stopper 113. The circular base 114 provides support for the outer cup body 110, preventing it from directly contacting the ground or tabletop and causing wear, thus effectively extending the service life of the outer cup body 110. The rubber stopper 113 can be placed through the through hole 115 on the circular base 114, keeping the heat dissipation hole 112 open to allow heat to dissipate from the insulation cavity. A mounting groove 116 is provided on the lower outer side of the outer cup body 110. An external thread is provided on the upper side of the outer wall of the circular base 114, and the circular base 114 is threadedly connected to the mounting groove 116. The circular base 114 is threadedly installed on the lower end of the outer cup body 110 by the external thread and the mounting groove 116. The operator can manually rotate the circular base 114 later. Remove it from the outer cup 110 to allow for the disassembly and replacement of the annular base 114. A sealing plate 117 is provided on the outer wall of the outer cup 110 at the lower end of the first external thread 111. A sealing ring is provided on the sealing plate 117, and the sealing ring abuts against the connecting part 121. The sealing plate 117 and the sealing ring seal the connection between the connecting part 121 of the inner cup 120 and the outer cup 110. Multiple heat dissipation holes 112 are provided, and the multiple heat dissipation holes 112 are evenly distributed in a ring along the bottom center of the outer cup 110. The multiple heat dissipation holes 112 facilitate the dissipation of heat, so that the heat in the heat insulation cavity can be dissipated more quickly. Both the outer cup 110 and the inner cup 120 are made of transparent PET material. The inner cup 120 is provided with scale lines. The use of transparent PET material for the outer cup 110 and the inner cup 120 allows the operator to know the amount of hot water in the inner cup 120 by looking at the outer cup 110 and the scale lines.
[0028] Combination Figures 1-4This embodiment of a plastic cup with an anti-scalding partition structure is used as follows: The inner cup body 120 is installed inside the outer cup body 110 under the action of the connecting part 121 and the first external thread 111. When the inner cup body 120 or the outer cup body 110 is damaged, the operator can manually rotate them to separate them so that the damaged body can be disassembled and replaced, saving resources. The heat dissipation holes 112 opened on the outer cup body 110 facilitate the dissipation of heat in the heat insulation cavity, further enhancing the anti-scalding effect of the plastic cup. The heat dissipation holes 112 can be sealed by the rubber stopper 113, so that the outer cup body 110 and the inner cup body 120 can be separated and used separately, thereby enhancing the practicality of the plastic cup. The outer cup body 110 and the inner cup body 120 are made of transparent PET material so that the operator can know the amount of hot water in the inner cup body 120 by looking at the outer cup body 110 and the scale lines.
