Problems solved by technology

[0004] However, pulp molded tableware is mainly made of raw materials such as paper, which has low hardness and is easily deformed during use. For example, tableware such as tableware, forks, and spoons are made, and the handles are easily deformed after being held by the user for a period of time. Moreover, the teeth of the fork have the problem of being easily broken, and there are also problems such as bending deformation between the handle of the table knife, fork, and spoon, and the operating part (hereinafter referred to as "main part").
Once tableware such as knives, forks, spoons are bent and deformed, the tableware can no longer be used, which limits the popularization and application of pulp molded tableware
[0005] For this reason, in some existing pulp molded tableware, thin sheets are provided on the periphery of the main body to increase the strength of the main body, but the problem of stress deformation at the handle is not considered. For example, the section at the handle includes the bottom wall and two When the user holds the handle, they often press their fingers against the two side walls of the handle, causing the two side walls to deform toward the middle. Due to the poor resilience of pulp molded tableware, when the user holds the handle for a long time After holding the handle, the handle is easy to deform, especially when holding a table knife to cut food forcefully, it is easier to deform the handle due to excessive holding force, which affects the use of pulp molded tableware
[0006] On the other hand, some existing pulp molded tableware are provided with reinforcing ribs on the main body or the handle, but the reinforcing ribs are sunken in one direction, that is, the reinforcing ribs are sunken from one plane to one direction, so that the reinforcing ribs The slope at the edge of the tableware has a sudden change, and the edge of the reinforcing rib is prone to cracking during molding, resulting in an increase in the defective rate of pulp molded tableware

no. 1 example

[0063] see Figure 1 to Figure 3 The high-strength environmentally friendly tableware in this embodiment is a pulp molded spoon, which has a long handle 10 and a main body 20 , and the main body 20 is arranged at one end of the handle 10 . When the spoon is used, the user usually holds the handle 10 with fingers, and the main body 20 is used to hold food. When the spoon is loaded with food, the main body 20 usually touches a hard object such as a plate, so the main body 20 and the handle 10 is the place where bending is most likely to occur. Once the main body 20 is bent relative to the handle 10, the spoon will no longer be usable. In order to strengthen the hardness of the connection between the main body 20 and the handle 10, in this embodiment Reinforcing ribs 30 are provided between the main parts 20 .

[0064] from figure 1 and figure 2 It can be seen that the reinforcing rib 30 is roughly elongated, extending from the handle 10 to the main body 20, see Figure 4 , ...

no. 2 example

[0081] see Figure 8 to Figure 10 The high-strength environmentally friendly tableware of this embodiment is a table knife made of environmentally friendly materials. The table knife includes a handle 40 and a main body 50 . Since the joint between the main body 50 and the handle 40 is the most prone to bending, in order to strengthen the hardness of the joint between the main body 50 and the handle 40 , a reinforcing rib 60 is provided between the handle 40 and the main body 50 in this embodiment.

[0082] The reinforcing rib 60 is roughly elongated, extending from the handle 40 to the main body 50, see Figure 11 , the reinforcing rib 60 is recessed from the upper surface of the table knife to the lower surface, and, on the cross-section of the extending direction of the reinforcing rib 60, the reinforcing rib 60 includes a concave portion 63 and a raised portion 64 located at both ends of the concave portion 63, 65.

[0083] The bottom wall of the recessed portion 63 is n...

[0092] see Figure 14 to Figure 16 The high-strength environmentally friendly tableware of this embodiment is a fork made of environmentally friendly materials. The fork includes a handle 70 and a main body 80. The handle 70 is elongated, and the main body 80 is located at one end of the handle 70. Since the joint between the main body 80 and the handle 70 is the most prone to bending, in order to strengthen the hardness of the joint between the main body 80 and the handle 70 , a reinforcing rib 90 is provided between the handle 70 and the main body 80 in this embodiment.

[0093] The reinforcing rib 90 is roughly elongated, extending from the handle 70 to the main body 80, see Figure 17 , the reinforcing rib 90 is recessed from the upper surface of the fork to the lower surface, and, on the section in the extending direction of the reinforcing rib 90, the reinforcing rib 90 includes a concave portion 99 and raised portions 95, 96 located at both ends of the concave portion 9...

Abstract

The invention provides high-strength environment-friendly tableware which comprises a handle and a main body part, and the main body part is located at one end of the handle; wherein the handle is provided with a recess, the recess forms a hollow part, the hollow part extends along the length direction of the handle, a reinforcer is arranged in the hollow part, and the first end of the reinforceris propped against the joint of the main body part and the handle. According to the high-strength environment-friendly tableware, the strength of the joint between the handle and the main body part can be improved, and the situation that the handle cannot be used due to the fact that the joint between the handle and the main body part is bent in the using process is avoided.

Description

technical field [0001] The invention relates to the field of tableware, in particular to a high-strength environment-friendly tableware made of paper pulp and other environment-friendly materials. Background technique [0002] Disposable tableware is common tableware. At present, disposable tableware is mainly plastic tableware, such as plates, knives, forks, spoons, forks and spoons made of plastic. Plastic tableware is usually made of materials that can be in direct contact with food. As people's awareness of environmental protection continues to increase, they realize that most of the plastic tableware on the market is not biodegradable, such as PP, PET, PE, etc. Therefore, people began to consider researching degradable tableware to replace plastic tableware. Among them, tableware made of polylactic acid (PLA) material is an industrially degradable tableware that can replace plastic tableware. However, due to the high cost of polylactic acid materials, polylactic acid ...
