Description
Technical Field
[0001] This utility model relates to the field of tableware technology, and in particular to a microwave-resistant PP bowl with heat-conducting reinforcing ribs. Background Technology
[0002] Polypropylene (PP) bowls are widely used in food packaging and catering due to their advantages such as being lightweight, non-toxic, and inexpensive. To meet the demands of modern fast-paced lifestyles, many PP bowls are designed for direct microwave heating. Existing technology incorporates upward-protruding support rings around the inner bottom of the bowl to increase its structural strength. The lid connects to both the bowl body and the inner support, allowing the bowl to withstand greater pressure. Polypropylene bowls are lightweight, easy to carry, and not easily broken.
[0003] For example, Chinese patent application number CN 201721069176.8 discloses a PP soup bowl, including a bowl body, an inner tray, and a lid. The bowl body has an upwardly protruding support ring around its inner bottom, and the inner tray rests on the support ring. Several vertical grooves are evenly distributed on the side wall of the bowl body, which, separated from the bowl body by the inner tray, can dissipate heat from the food inside the inner tray in a timely manner, providing excellent ventilation and heat dissipation. The grooves also increase the bowl's structural strength. However, during microwave heating, heat often concentrates in a localized area of the food or bowl, making it difficult to distribute evenly. This leads to uneven heating, causing localized softening, deformation, or even collapse of the bowl. Therefore, its thermal conductivity and resistance to deformation need improvement. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a microwave-resistant PP bowl with thermally conductive reinforcing ribs to solve the technical problem that in the microwave heating process, heat is often concentrated in a local area of the food or bowl, which is difficult to diffuse evenly, resulting in local softening, deformation or even collapse of the bowl due to uneven heating, and the thermal conductivity and deformation resistance need to be improved.
[0005] Based on the above objectives, this utility model provides a microwave-resistant PP bowl with thermally conductive reinforcing ribs, comprising a bowl body and an insulated inner liner disposed inside the bowl body. The insulated inner liner is integrally formed with the bowl body. A plurality of storage slots are evenly distributed on the outer side of the bowl body, and each storage slot contains a thermally conductive reinforcing rib body. Each of the thermally conductive reinforcing rib bodies can be flipped onto the bowl body. The microwave-resistant PP bowl also includes: A retaining ring is movably fitted onto the outside of the bowl body, and the inside of the retaining ring is provided with a limiting protrusion; The top end of the thermally conductive reinforcing rib body can be inserted into the slot located inside the fixing ring.
[0006] Furthermore, the bowl body is provided with guide grooves between adjacent storage slots, the width of the guide grooves gradually decreases from top to bottom, and the limiting protrusions are slidably disposed within the guide grooves.
[0007] Furthermore, the degree of protrusion of the limiting protrusion gradually decreases from top to bottom.
[0008] Furthermore, the rim of the bowl is folded outward to form a reinforced rolled edge.
[0009] Furthermore, the width of the reinforced rolled edge covers the fixing ring.
[0010] Furthermore, a movable gap is provided between the reinforcing rolled edge and the fixing ring.
[0011] Furthermore, the bottom of the bowl is provided with an anti-slip concave ring.
[0012] Furthermore, the bowl body is made of heat-resistant polypropylene material.
[0013] The beneficial effects of this utility model are as follows: When in use, the fixing ring is slid down, and the slot inside the fixing ring will lock the top of the heat-conducting reinforcing rib body. The limiting protrusion inside the fixing ring provides damping and staged positioning during the sliding process, forming a stable reinforcing structure, which simultaneously enhances the thermal conductivity and deformation resistance.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.
[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0019] The first aspect of this utility model proposes a microwave-resistant PP bowl with thermally conductive reinforcing ribs, such as... Figure 1-5 As shown, the bowl includes a bowl body 1 and an insulated inner liner 2 located inside the bowl body 1. The insulated inner liner 2 is integrally formed with the bowl body 1. Several storage slots 3 are evenly distributed on the outer side of the bowl body 1. The storage slots 3 are provided with heat-conducting reinforcing rib bodies 4. Several heat-conducting reinforcing rib bodies 4 can be flipped onto the bowl body 1. The microwave-resistant PP bowl also includes: A retaining ring 5 is movably fitted onto the outside of the bowl body 1, and a limiting protrusion 6 is provided inside the retaining ring 5; The top end of the heat-conducting reinforcing rib body 4 can be inserted into the slot 7 located inside the fixing ring 5.
[0020] In this embodiment, during use, the inner side of the bowl 1 has an insulated inner liner 2, which plays a basic role in heat preservation. The outer side of the bowl 1 is provided with multiple storage slots 3. Each storage slot 3 is equipped with a rotatable heat-conducting reinforcing rib body 4. When heating is required, the fixing ring 5 is slid down. The slot 7 inside the fixing ring 5 will lock the top of the heat-conducting reinforcing rib body 4. The limiting protrusion 6 inside the fixing ring 5 provides damping and staged positioning during the sliding process, forming a stable reinforcing structure, which simultaneously enhances the thermal conductivity and resistance to deformation.
[0021] In this embodiment, as Figure 2 As shown, a guide groove 8 is provided on the bowl body 1 between adjacent storage grooves 3. The width of the guide groove 8 gradually decreases from top to bottom. The limiting protrusion 6 is slidably disposed in the guide groove 8. The guide groove 8 provides a precise path for the up and down movement of the fixing ring 5, preventing it from deflecting or getting stuck. Since the guide groove 8 gradually narrows from top to bottom, when the fixing ring slides down to lock the rib body, the limiting protrusion 6 and the gradually narrowing groove wall will generate an increasing squeezing force, forming a self-locking effect, making the fixing ring less likely to loosen during heating and vibration, and the locking more reliable.
[0022] In this embodiment, as Figure 5 As shown, the protrusion of the limiting protrusion 6 gradually decreases from top to bottom, so that the resistance of the fixing ring 5 is small when it initially slides down, and the resistance increases gradually as it goes down, providing a clear sense of phased positioning and improving the operating experience.
[0023] In this embodiment, as Figure 2 As shown, the rim of the bowl 1 is folded outward to form a reinforced rolled edge 9, which greatly enhances the strength and rigidity of the rim and prevents it from deforming under stress or heat.
[0024] In this embodiment, as Figure 2 As shown, the width of the reinforced rolled edge 9 covers the fixed ring 5, and there is an movable gap 10 between the reinforced rolled edge 9 and the fixed ring 5, which ensures that the fixed ring 5 will not be pressed down by the rolled edge, and retains its necessary movable space, so that the up and down sliding operation is always smooth and unobstructed.
[0025] In this embodiment, as Figure 2 As shown, the bottom of the bowl 1 is provided with an anti-slip concave ring 11, which reduces the contact area between the bottom of the bowl and the table surface, increases static friction, and effectively prevents the bowl from sliding on the table surface, especially when eating with a spoon.
[0026] In this embodiment, the bowl body 1 is made of heat-resistant polypropylene material. Heat-resistant PP can withstand the high temperature environment of microwave oven heating without releasing harmful substances or undergoing severe softening, thus ensuring the usability and safety of the product from the material source.
