[0033] Example

[0034] Please refer to Figures 1-4 The utility model provides a disposable paper bowl, comprising an outer bowl body 1, an inner bowl body 2, an extension layer 3, a telescopic layer 4, a base 5, and a fastener 6.

[0035] Furthermore, the outer bowl body 1 is a harder paper structure, which is used to stabilize the shape of the entire paper bowl. The outer surface of the bowl body is covered with a waterproof film to enhance the waterproofness.

[0036] Furthermore, an inner bowl body 2 is arranged inside the outer bowl body 1 , an extension layer 3 is arranged inside the bowl edge of the outer bowl body 1 , and an extension end of the extension layer 3 is connected to the bowl edge of the inner bowl body 2 .

[0037] When the extension layer 3 is subjected to external force, such as the gravity generated by the food contained in the inner bowl body 2, it will extend, causing the inner bowl body 2 to move, thereby increasing the capacity of the inner bowl body 2.

[0038] A telescopic layer 4 is connected between the two bowl bodies. The telescopic layer 4 will shrink when subjected to external force. The telescopic layer 4 will generate elastic force when shrinking, thereby providing elastic shock absorption for the inner bowl body 2 when holding food.

[0039] Please refer to Figure 2 In this embodiment, the extension layer 3 includes a rib 301 and a winding paper sheet 302 .

[0040] Specifically, a ring-shaped rib 301 is fixed to the inner wall of the bowl edge of the outer bowl body 1, and the bottom of the rib 301 is fixedly connected to one end of the rolled-up paper sheet 302, and the other end of the rolled-up paper sheet 302 is fixedly connected to the bowl edge of the inner bowl body 2. The rolling structure of the rolled-up paper sheet 302 is spiral-shaped.

[0041] Preferably, the inner bowl body 2 itself is also made of a hard paper structure coated with a waterproof film, which is difficult to deform to prevent it from being broken when holding hard food or when guests are dining. When the inner bowl body 2 is filled with food, the inner bowl body 2 is subjected to gravity, which will cause the paper sheets in the rolled paper sheet 302 to extend, ensuring that the inner bowl body 2 moves toward the inner bowl of the outer bowl body 1, thereby increasing the capacity of the inner bowl body 2.

[0042] The annular rib 301 on the edge of the outer bowl body 1 can prevent soup from spilling out when the soup is placed in the bowl body; and the double-layer bowl body can effectively prevent overly hot food from being transferred to the outside of the outer bowl body 1 and causing burns.

[0043] In this embodiment, the telescopic layer 4 is configured as a bent paper sheet, and a plurality of bent paper sheets are evenly arranged between the outer bowl body 1 and the inner bowl body 2 .

[0044] Preferably, the bent paper sheet is bent multiple times, and the paper sheet after multiple bends will generate elastic force at the bends, so that the bent paper sheet has elastic force. Therefore, when several bent paper sheets are arranged between the two bowl bodies, they will act as elastic members.

[0045] Preferably, when the inner bowl body is filled with lighter food, such as vegetable leaves, the inner bowl body 2 will basically maintain its original shape and the displacement will be small; when the inner bowl body is filled with heavier food, such as soup, porridge, etc., the inner bowl body 2 will be displaced by gravity, the extension layer 3 will be extended synchronously, and the bent paper will be elastically displaced. At this time, when the bowl body is picked up by hand or transported for takeout, the shaking of the external environment will be transmitted to the outer bowl body 1. At this time, the active state of the bent paper can absorb part of the shaking force transmitted by the outer bowl body, which has a shock-absorbing and anti-swaying effect, and reduces the occurrence of food spilling from the inner bowl body.

[0046] It is worth noting that the rolled paper sheet 302 is located inside the inner bowl body 2 and will therefore come into contact with food. When serving soup, a small amount of soup will enter the spiral structure of the rolled paper sheet 302 during shaking, which will not affect the extension function of the rolled paper sheet 302, but will make it difficult to clean. However, since the bowl body is a disposable paper bowl, there is no need to consider subsequent cleaning issues.

[0047] Furthermore, a base 5 is provided at the bottom of the outer bowl body 1 to increase the firmness of the bottom of the bowl body.

[0048] In this embodiment, the base 5 includes a supporting edge 501 and a cross paper board 502 .

[0049] The support edge 501 is fixed to the bottom surface of the outer bowl body 1. The support edge 501 is formed into a ring structure or a rectangular structure. The support edge 501 has a certain height to prevent water from seeping into the bottom surface of the outer bowl body when the bowl body is placed on a water surface, causing the outer bowl body to soften and crack under long-term contact.

[0050] A cross cardboard 502 is arranged in the annular structure or rectangular structure of the support edge 501. The cross cardboard 502 is made up of several cardboards arranged crosswise to increase the firmness of the support edge 501 so that the support edge 501 is not easily softened after being in contact with water for a long time.

[0051] Furthermore, a fastener 6 is sleeved on the outer wall of the outer bowl body 1 to increase the stability of the entire bowl body.

[0052] Please refer to Figure 2-Figure 4 In this embodiment, the fastener 6 includes an elastic ring 601 , a paper film 602 , and a bending piece 603 .

[0053] Specifically, the elastic ring 601 is an elastic rubber structure. The elastic ring 601 is sleeved on the outer wall of the outer bowl body 1, and can apply elastic force to the bowl wall of the outer bowl body 1, thereby increasing the stability of the outer bowl body 1 and preventing it from being easily deformed by guests or being stretched by the food inside.

[0054] In addition, one end of the paper film 602 is fixedly connected to the elastic ring 601, and the surface of the paper film 602 matches the shape of the outer wall of the outer bowl body 1. The paper film 602 is an annular membrane structure, which is covered in an annular shape on the surface of the outer bowl body 1. The paper film 602 has a certain thickness and can wrap the outer wall of the bowl body to provide protection and increase the stability of the outer bowl body 1.

[0055] A bending piece 603 is fixed on the paper film 602 , and two bent ends of the bending piece 603 are fixedly connected to two ends of the paper film 602 respectively.

[0056] The bending piece 603 is configured as an arc-shaped rubber pad, which is elastic.

[0057] Preferably, when the food contained in the bowl is too heavy and difficult to be lifted by hand, the arc-shaped rubber pad can be manually pressed to move one end away from the elastic ring 601. Due to its arc-shaped elastic structure, the arc-shaped rubber pad will bend and deform during the pressing, and the opening formed after the bending is directed toward the center of the outer bowl body 1. At this time, the two curved ends of the arc-shaped rubber pad will slowly approach each other until both ends of the arc-shaped rubber pad abut against the elastic ring 601 and are blocked, and the arc-shaped rubber pad will also synchronously drive the paper film 602 to bend and deform, forming an annular platform composed of the paper film 602 and the arc-shaped rubber pad at the elastic ring 601 for human hands to hold in order to lift the entire bowl body.

[0058] It is worth noting that the outer surface of the paper film 602 can be painted with the store's logo to attract customers. In addition, the end of the paper film 602 away from the elastic ring 601 is pleated (not shown in the figure). After being bent by the curved rubber pad, the pleated structure of the paper film 602 can expand, increasing the annular diameter of the paper film 602 at this end so that it can fit the larger outer wall of the bowl body.

[0059] Thus far, various embodiments of the present invention have been described in detail. To avoid obscuring the concept of the present invention, some details known in the art have been omitted. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions of the present invention. The scope of the present invention is defined by the appended claims.
