Description

Technical Field

[0001] This utility model mainly relates to the field of plastic tableware technology, specifically a heat-insulating disposable plastic tableware. Background Technology

[0002] Plastic cutlery is relatively inexpensive and widely used in the takeout market where disposable cutlery is in demand. Currently, in Western food takeout scenarios such as steak, the knife, fork, and food container are usually stored separately. However, the knife and fork, due to their sharpness, can easily damage the external packaging structure, posing a certain risk. Furthermore, the knife and fork lack heat insulation during takeout delivery, and in cold weather, they can easily become too cold, affecting the taste of the food after cutting. Utility Model Content

[0003] In view of the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a heat-insulated disposable plastic tableware, which sets the fork and knife on the lunch box, with a stable structure and heat insulation for the fork and knife.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a heat-insulated disposable plastic tableware, including a lunch box, a lid on the lunch box, a fork and a knife on the lid, a fork cavity and a knife cavity formed on the lid, a heat-insulating layer on the inner wall of the fork cavity and the knife cavity, a high-strength layer on the inner wall of the heat-insulating layer, the fork and the knife respectively located within the two high-strength layers, and a heat-insulating plate slidably disposed on the top of the fork cavity and the knife cavity.

[0005] Preferably, the top of the lunch box has two sliding grooves, and the bottom of the heat insulation plate has at least one slider at the corresponding position of the two sliding grooves, and the sliding grooves and sliders are matched.

[0006] Furthermore, at least one set of elastic blocks is formed in pairs within any one of the sliding grooves, and a snap-fit ​​protrusion is formed at the bottom of any one of the sliding blocks. The snap-fit ​​protrusion slides along the sliding groove and is snapped into the set of elastic blocks.

[0007] Furthermore, the elastic block is a hemispherical structure, and the snap-fit ​​protrusion is also a hemispherical structure. The diameter of the snap-fit ​​protrusion is the same as the distance between the two elastic blocks in the same group. The elastic block and the snap-fit ​​protrusion elastically snap together to restrict the heat insulation plate from sliding along the groove direction.

[0008] Preferably, a fixing block is provided on each of the two side walls of the lid, and a connecting shaft is rotatably provided in any one of the fixing blocks. Buckles are fixed at both ends of the connecting shaft. A plate is provided on each of the two side walls of the lunch box. The buckles fit into the plate, and the lid and the lunch box are fixed by the buckles and the plate.

[0009] Furthermore, handles are fixed at both ends of the connecting shaft. The handles are perpendicular to the buckle. The position of the buckle on the handles ensures that the handles at both ends remain horizontal when the buckle is engaged with the mounting plate, making it easy to pick up the lunch box.

[0010] Preferably, a separation cavity is provided between the lunch box and the lid, the outer wall of the separation cavity is tightly against the inner wall of the lunch box, and the top of the separation cavity forms an outward flange.

[0011] Furthermore, an expansion groove is formed at the bottom of the lid, and the inner wall of the expansion groove is connected to the inner wall of the separation cavity to expand the accommodating space of the separation cavity, so as to accommodate more food through the expansion groove.

[0012] Furthermore, a locking block is formed at the bottom of the lid, a first locking groove is formed on the flange to fit the locking block, and a second locking groove is formed at the top of the lunch box to fit the locking block. The locking block is engaged by the first and second locking grooves to restrict the separation chamber from moving horizontally out of the lunch box.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The high-strength layers inside the fork and knife cavities accommodate the fork and knife, integrating them into the lid for enhanced structural stability. Furthermore, the heat insulation layer on the outer wall of the high-strength layer and the top heat insulation plate provide relative heat insulation and sealing to the outside of the food container. Simultaneously, the close proximity of the bottom of the fork and knife cavities to the expansion slots allows heat from the food inside the separation chambers to warm the bottom of the fork and knife cavities along the expansion slots, preventing the fork and knife from cooling down too quickly and affecting the taste of the cut food.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] This utility model provides a heat-insulating disposable plastic tableware, which sets the fork and knife on the food box, and has a stable structure and provides heat insulation for the fork and knife.

[0020] like Figures 1 to 5 As shown, a heat-insulated disposable plastic tableware includes a lunch box 1. A lid 2 is provided on the top of the lunch box 1. A fork 5 and a knife 6 are provided on the lid 2. A fork cavity 28 and a knife cavity 29 are formed on the lid 2. The inner walls of both the fork cavity 28 and the knife cavity 29 are provided with a heat-insulating layer 7. The heat-insulating layer 7 is made of polystyrene foam, which is lightweight, has good heat retention, and is not easily affected by moisture. A high-strength layer 8 is provided on the inner wall of the heat-insulating layer 7. The high-strength layer 8 is made of polycarbonate plastic, which has high strength and is resistant to high temperatures. The fork 5 and the knife 6 are located within the two high-strength layers 8, respectively, making it difficult to damage the high-strength layers 8. A heat-insulating plate 3 is slidably provided on the top of the fork cavity 28 and the knife cavity 29. The heat insulation board 3 is made of polypropylene plastic, which is inexpensive and has good heat insulation performance.

[0021] The top of the lunch box 1 has two sliding grooves 22, and any one of the sliding grooves 22 has an inverted T-shaped structure. The bottom of the heat insulation plate 3 has two sliders 31 at the corresponding positions of the two sliding grooves 22. The sliding grooves 22 and the sliders 31 fit together. Two sets of elastic blocks 23 are formed in pairs in any one of the sliding grooves 22. A snap-fit ​​protrusion 32 is formed at the bottom of any one of the sliders 31. The snap-fit ​​protrusion 32 slides along the sliding groove 22 and is snapped into a set of elastic blocks 23. The elastic blocks 23 have a hemispherical structure. The snap-fit ​​protrusion 32 also has a hemispherical structure. The diameter of the snap-fit ​​protrusion 32 is the same as the distance between the two elastic blocks 23 in the same set.

[0022] A fixing block 24 is respectively provided on the front and rear side walls of the lid 2. A connecting shaft 25 is rotatably provided inside any fixing block 24. Both ends of the connecting shaft 25 penetrate the fixing block 24 and are fixed with buckles 27. The buckles 27 have a U-shaped structure. A plate 12 is respectively provided on the front and rear side walls of the lunch box 1. The cross section of the plate 12 is hook-shaped. The U-shaped horizontal axis of the buckle 27 is engaged with the hook part of the plate 12. The buckle 27 is preferably made of polyethylene plastic, which has good flexibility and elasticity and is easy to engage or disengage from the plate 12. Handles 26 are also fixed at both ends of the connecting shaft 25. The handles 26 are perpendicular to the buckles 27. When the buckles 27 are engaged with the plate 12, the handles 26 remain horizontal and easy to grip.

[0023] A separation cavity 4 is provided between the lunch box 1 and the lid 2. The outer wall of the separation cavity 4 is close to the inner wall of the lunch box 1. The top of the separation cavity 4 forms a flange 41, the length of which is the same as the thickness of the side wall of the lunch box 1. The bottom of the lid 2 forms an expansion groove 210. The inner wall of the expansion groove 210 is connected to the inner wall of the separation cavity 4 to expand the accommodating space of the separation cavity 4. The bottom of the lid 2 forms a locking block 21. A first locking groove 42 that fits into the locking block 21 is formed on the flange 41. A second locking groove 11 that fits into the locking block 21 is formed at the top of the lunch box 1. The locking block 21 is inserted into the first locking groove 42 and the second locking groove 11 in sequence to restrict the separation cavity 4 from moving horizontally away from the lunch box 1.

[0024] The implementation principle of this application embodiment is as follows: When using this product, refer to... Figures 2 to 5As shown, each structure is initially kept separate. Part of the food is placed into the lunchbox 1 and then along the inner wall of the lunchbox 1 into the separation cavity 4. The remaining food is then placed along the inner wall of the separation cavity 4, and the lid 2 is closed. The buckle 27 is flipped until it engages with the latch plate 12 to secure the lunchbox 1, lid 2, and separation cavity 4. Next, the fork 5 and knife 6 are placed along the inner walls of the two high-strength layers 8 into the fork cavity 28 and knife cavity 29, respectively. The knife 5 and fork 6 are less likely to damage the high-strength layer 8, making the structure relatively stable. Finally, the heat insulation plate 3 is slid along the slide groove 22 to overcome the elasticity of the elastic block 23 until the latching protrusion 32 is precisely positioned between the two elastic blocks 23. At this point, the overall structure is as follows (refer to the previous section). Figure 1 As shown, the heat insulation layer 7 on the outer wall of the high-strength layer 8 works in conjunction with the heat insulation plate 3 to isolate the fork 5 and knife 6 from the external space of the food container 1. At the same time, the hot air emitted by the food in the separation cavity 4 heats the bottom of the fork cavity 28 and knife cavity 29 along the expansion groove 210, thereby preventing the fork 5 and knife 6 from losing temperature too quickly and affecting the taste of the food after cutting.
