Description

Technical Field

[0001] This utility model relates to the field of disposable containers, specifically to a disposable container with a flange on the top. Background Technology

[0002] In a disposable paper container strong shaping process disclosed in Chinese patent document CN113619190B, the inventors pressed strong indentation lines into the bottom of the lid and body of the product made in step 2. This strong indentation line formation increases the bottom support strength. Simultaneously, a groove structure for engaging with a snap-fit ​​structure is cut into the sloping surface of the body, and a protrusion is pressed into the end edge of the lid, while a groove is pressed into the end edge of the body. When the lid and body are closed, the protrusion engages with the groove, forming a better snap-fit ​​connection and providing horizontal shaping. However, this primarily protects a strong shaping process, and the groove structure cut into the body requires engagement with the protrusion on the lid for a snap-fit ​​connection. In disposable containers that do not require a lid, such as paper bowls, paper plates, paper food containers, or paper food platters, it is generally considered unnecessary to design a groove and protrusion engagement structure. However, the inventors discovered that the top flange design also has some specific technical effects in these disposable containers that do not require a lid, thus leading to this utility model. Utility Model Content

[0003] In view of this, in order to solve the above-mentioned technical problems, the purpose of this utility model is to propose a disposable container with a flange at the top, which can enhance the stiffness and strength of the entire disposable container.

[0004] The technical solution adopted is as follows:

[0005] A disposable container with a flange on the top, characterized in that it comprises a body, the body including a bottom, a side and a top, the side being formed by multiple separate folds that are pressed together in pairs or by adhesive parts, the multiple folds surrounding the bottom to form an accommodating space in the shape of a frustum or approximately a frustum, the top surrounding the side; and the top having a three-dimensional flange.

[0006] Furthermore, the top of the main body includes an interior, a middle section, and an exterior. The interior is a transitional plane, the middle section is provided with the three-dimensional flange, and the cross-sectional shape of the three-dimensional flange is square, trapezoidal, or semi-circular. One end of the exterior is integrally connected to the middle section.

[0007] Furthermore, the outer edge is either straight or curved.

[0008] Furthermore, the outer side is a straight edge with an inwardly folded edge, the end of which may or may not abut against the side portion.

[0009] Furthermore, the outer part is arc-shaped and has an inwardly folded edge, the end of which may or may not abut against the side portion.

[0010] Furthermore, the outer edge is a straight edge with a vertically downward folded edge.

[0011] Furthermore, the three-dimensional flange is either entirely curved or partially curved.

[0012] Furthermore, the bottom is provided with a downwardly protruding support foot.

[0013] Furthermore, the disposable container is a paper bowl, paper plate, paper food dish, or paper food tray.

[0014] Furthermore, the bottom is a polygon or a circle with four or more sides, and the supporting leg is a polygon or a circle with four or more sides.

[0015] The beneficial effects of this utility model are as follows:

[0016] Because the top has a three-dimensional flange, it can enhance the stiffness and strength of the entire disposable container top; because the side is made up of multiple separate and independent folds pressed together in pairs, and the multiple folds surround the bottom to form a frustum-shaped or near-frustum-shaped accommodating space, it can enhance the stiffness and strength of the entire disposable container side.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example 1

[0042] See Figure 1 As shown, a disposable container with a flange on the top includes a main body, which includes a bottom 1, a side 2, and a top 3. The side is formed by multiple separate folds that are pressed together in pairs or by adhesive parts. The multiple folds surround the bottom to form a frustum-shaped accommodating space. The top 3 surrounds the side 2. The top 3 of the main body includes an inner part 31, a middle part 32, and an outer part 33. The inner part 31 is a transitional plane. The middle part 32 is provided with a three-dimensional flange. The cross-sectional shape of the three-dimensional flange is square, trapezoidal, or semi-circular. One end of the outer part is integrally connected to the middle part. In this embodiment, the three-dimensional flange is square.

[0043] In one specific embodiment, the side part is formed by pressing and fixing multiple separate folds together in pairs, which involves partially overlapping the folds and pressing them together to form a two-layer connection structure; in another specific embodiment, the side part is formed by pressing and fixing multiple separate folds together in pairs through adhesive parts, which involves bonding the folds together in pairs through adhesive parts to form a three-layer connection structure.

[0044] In this embodiment, the outer edge of the top 3 is straight.

[0045] Because a three-dimensional flange is provided in the middle section, such as a square three-dimensional flange in this embodiment, the three-dimensional flange has a certain height and width, which can enhance the rigidity and edge strength of the entire disposable container.

[0046] This makes the entire disposable container less prone to deformation when subjected to inward squeezing forces.

[0047] The disposable container can be, for example, a paper bowl, paper plate, paper food dish, or paper food platter. This embodiment uses a paper bowl. The bottom of the disposable container can be a polygon with four or more sides, such as a square, pentagon, hexagon, heptagon, or octagon. This embodiment uses an octagon as an example. That is, the disposable container in this embodiment is a paper bowl with an octagonal bottom, or simply an octagonal bowl.

[0048] In one preferred embodiment, the octagonal bowl has a downwardly protruding support foot at the bottom. The support foot has a V-shaped cross-section. The support foot serves three purposes: first, it provides an anti-slip function, preventing increased friction on the table; second, it provides heat insulation, so that if the paper bowl contains hot food, hands do not directly touch the hot bottom; and third, it increases the overall strength of the bottom edge.
