Description

Technical Field

[0001] This utility model belongs to the technical field of disposable food packaging, and relates to disposable dinner plates. Background Technology

[0002] With the rapid development of the food delivery industry, disposable tableware has become a mainstream product in the food packaging field due to its convenience and low cost. Plates are flat, universal tableware with a wide range of uses. Most existing disposable plates feature a flat or shallowly curved bottom design. Due to cost considerations, disposable plates are all thin-walled, with a wall thickness of only 0.3-0.8mm. This results in poor bending resistance, making them prone to collapse and deformation when holding hot food or soup. As a basic consumable in the modern catering industry, achieving a balance between structural strength and lightweight design remains a key technical challenge for disposable plates.

[0003] To increase the strength of the bottom of disposable plates, some plates have radial straight ribs. However, the installation of these straight ribs can cause food to be stacked unevenly, and stress concentration can easily occur at the intersection of the ribs, leading to cracking. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a disposable plate that increases the structural strength of the plate, especially the bottom.

[0005] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

[0006] A disposable plate includes an integrally formed plate bottom, plate wall, and plate rim. The plate wall extends upward from the periphery of the plate bottom, and the plate rim is connected to the top of the plate wall. The plate bottom, plate wall, and plate rim form an open upper accommodating space. The plate bottom is provided with a wave-shaped reinforcement structure, which includes a plurality of continuously arranged concentric rings. Adjacent concentric rings have a height difference and / or arc undulations, so that the wave-shaped reinforcement structure forms a continuous wave shape in the radial cross section.

[0007] In the aforementioned disposable plate, a central circle is provided at the center of the bottom of the plate and an outer ring is provided at the edge. The wave-shaped reinforcing structure connects the central circle and the outer ring, and the central circle, concentric ring and outer ring are arranged concentrically.

[0008] In the aforementioned disposable plate, the concentric ring can be a planar ring structure or a curved ring structure; when the concentric ring is a planar ring structure, the wave-shaped reinforcement structure can form a stepped wave structure; when the concentric ring is a curved ring structure, the wave-shaped reinforcement structure can form an arc-shaped undulating wave structure.

[0009] In the aforementioned disposable plate, the outer edge ring is inclined, with its inclined surface tilting upward from the outside to the inside and its extended surface intersecting the central circle, and the wave-shaped reinforcing structure is arranged along the extended surface.

[0010] In the aforementioned disposable plate, the concentric rings are continuously distributed according to the same waveform periodicity, and each waveform period includes at least one peak segment and one trough segment; specifically, each waveform period includes multiple concentric rings, and includes at least one peak surface concentric ring and one trough surface concentric ring.

[0011] In the aforementioned disposable plate, the distance between the crests and troughs of the wave-shaped reinforcement structure is 0.5-2 mm.

[0012] In the aforementioned disposable plate, the rim of the plate is connected to the top of the plate wall by an auxiliary wave structure, which is composed of several concentrically arranged annular convex strips, and the annular convex strips are continuously undulating in the circumferential cross section.

[0013] In the aforementioned disposable plate, the outer edge of the plate rim is provided with a downward-facing flange, and the end of the flange is provided with an outwardly extending thickened edge.

[0014] The wave-shaped reinforcing structure provided by this utility model can be applied to plates made of all materials and processes. Preferably, the plate is formed by starch foaming and molding.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This invention provides a disposable plate with an added wave-shaped reinforcing structure. This structure utilizes the mechanical principles of waves to disperse external forces, enhancing the overall structural strength of the plate. Compared to conventional disposable plates with flat or simply shaped bottoms, it exhibits superior performance in terms of pressure resistance and deformation resistance. Furthermore, the wave-shaped bottom structure of this invention prevents soup and liquid from spilling, reducing liquid spillage when handling the plate. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 :

[0022] A disposable plate includes an integrally formed plate base 1, plate wall 2, and plate rim 3. The plate wall 2 extends upward from the periphery of the plate base 1, and the plate rim 3 is connected to the top of the plate wall 2. The plate base 1, plate wall 2, and plate rim 3 form an open upper accommodating space. The plate base 1 is provided with a wave-shaped reinforcement structure, which includes a plurality of continuously arranged concentric rings 4. Adjacent concentric rings 4 have a height difference and / or arc surface undulations, so that the wave-shaped reinforcement structure forms a continuous wave shape in the radial cross section.

[0023] In this embodiment, the structural strength of the plate bottom 1 is increased by a wave-shaped reinforcement structure. The plate is formed by foaming starch and molding. During the foaming and molding process, the wave-shaped reinforcement structure is formed synchronously with the plate. The concentric ring 4 in this embodiment can use different structures. For example, the concentric ring 4 can be a planar ring structure or a curved ring structure. When the concentric ring 4 is a planar ring structure, the wave-shaped reinforcement structure can form a stepped wave structure. When the concentric ring 4 is a curved ring structure, the wave-shaped reinforcement structure can form an arc-shaped undulating wave structure.

[0024] In this embodiment, the concentric rings 4 are continuously distributed according to the same waveform periodicity, and each waveform period includes at least one peak segment and one trough segment; specifically, each waveform period includes multiple concentric rings 4, and includes at least one peak surface concentric ring 4 and one trough surface concentric ring 4; for example, the continuous waveform periodic distribution can take the following form: peak surface concentric ring 4 - trough surface concentric ring 4 - peak surface concentric ring 4 - trough surface concentric ring 4; or planar concentric ring 4 - peak surface concentric ring 4 - trough surface concentric ring 4 - planar concentric ring 4 - peak surface concentric ring 4 - trough surface concentric ring 4.

[0025] Furthermore, a central circle 5 is provided at the center of the bottom plate 1, and an outer edge ring 6 is provided at the edge. The wave-shaped reinforcing structure connects the central circle 5 and the outer edge ring 6. The central circle 5, the concentric ring 4, and the outer edge ring 6 are concentrically arranged.

[0026] Furthermore, in order to further prevent the bottom of the tray 1 from collapsing and deforming during filling, the outer edge ring 6 is inclined, with its inclined surface tilting upward from the outside to the inside and its extended surface intersecting the central circle 5, and the wave-shaped reinforcing structure is arranged along the extended surface.

[0027] Preferably, the distance between the wave crest and the wave trough of the wave-shaped reinforcement structure is 0.5-2mm.

[0028] To enhance the overall strength of the plate, the rim 3 and the top of the plate wall 2 are connected by an auxiliary wave structure. The auxiliary wave structure is composed of several concentric annular convex strips 7, which are continuously undulating in the circumferential cross section.

[0029] Furthermore, the outer edge of the disc rim 3 is provided with a downward flange 8, and the end of the flange 8 is provided with an outwardly extending thickened edge 9.
