Description

Technical Field

[0001] The invention relates to the technical field of food packaging barrel equipment, in particular to a disposable daily edible food packaging barrel. Background Art

[0002] Disposable practical food packaging barrels, as an important packaging link in the food industry, have been rapidly developed. In terms of food packaging applications, the quality and practicality of products have been improved. How to achieve both meeting the requirements of life and effectively controlling costs? The one-piece bottom groove process for the handle is currently the only injection molding process in the country. In the injection molding process, 1. It is necessary to combine the original split handle and the barrel as a whole, and add reinforcement ribs at the bend of the handle. After it has a certain strength, it prevents the handle from falling off when the user uses it again. 2. The bottom groove structure is used to buffer the impact force and prevent stacking deformation. An insulating air layer is established to reduce the risk of burns caused by heat conduction. The handle and the barrel body are integrated into one molding, reducing costs and improving structural reliability. Chinese patent publication number CN215795830U adopts an external handle design, which is assembled with the barrel body after injection molding. This solution has the following problems: Poor reliability: stress concentration at the handle connection increases the risk of breakage when the load exceeds 3kg (industry test data shows that the shedding rate is as high as 18%). High cost: an additional 0.12-0.15 yuan / piece of injection molding cost and assembly process; Insufficient environmental friendliness: Components made of different materials make recycling difficult, violating the European Union (EU) Directive 2019 / 904's requirement for a single material. Insufficient impact resistance of the bottom; Most mainstream products use a flat bottom design, resulting in: Fragile when stacked: The bottom is subjected to pressure exceeding 50N / cm during transportation 2 Plastic deformation occurs (laboratory simulation data shows that the breakage rate of 10 layers is 27%); Lack of thermal insulation: The flat structure directly conducts heat, and when filled with 80°C liquid, the outer surface temperature of the bottom reaches 68-72°C (posing a scalding hazard); Ineffective insulation solutions; Inefficient production processes; The industry's common production process has obvious shortcomings: Multi-step production: Step-by-step operations such as handle assembly and insulation layer lamination limit the production speed to less than 200 pieces per hour; High scrap rate: The composite process results in a 12-15% defective rate (mainly concentrated in the handle connection and bottom molding area); High mold complexity: Traditional anti-scalding structures require 4-6 sets of ejection mechanisms, increasing mold manufacturing costs by 35%; And it fails to effectively resolve the triangular contradiction of "structural strength-thermal insulation performance-cost control". Summary of the Invention

[0003] The object of the present invention is to provide a disposable food packaging barrel for daily use to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a disposable food packaging barrel, comprising a handle structure 1, wherein the handle structure 1 includes a handle 3, a transition block 4, and a reinforcing rib plate 5, wherein the side end of the handle 3 is fixedly connected to the transition block 4, and the side end of the transition block 4 is fixedly connected to the reinforcing rib plate 5, and the lower end of the handle structure 1 is integrally formed with the barrel body; A base 6 is provided at the bottom of the barrel body, and the handle structure 1, the barrel body and the base 6 are integrally formed by injection molding.

The handle ends are horizontally injected, and the middle of the handle is vertically injected. There is a connecting block 2 between the handle and the barrel body to ensure the product is fixed before use. The connecting block 2 is thickened to 1.6mm to reduce stress concentration. The R angle is 9.1mm. The arc surface functions to prevent bumps and collisions. The root thickness gradient design avoids sudden stress. The reinforcing rib 5 is 1.5mm high and 1.3mm wide. It serves to increase strength and prevent deformation of the connection when bending. The transition block 4 is the horizontal and vertical connection point of the handle. The transition position has a transition arc angle of 2.9mm and is connected to a 1.8mm straight line segment with another 2.9mm arc angle, thereby improving the strength and toughness of the handle.

Mechanical properties: Laboratory pressure test shows that 50N / cm 2 Deformation under load <0.3mm drop test (1.2m height) pass rate 100% (GB / T 4857.5 standard); Air layer effect: The outer edge of the groove is 1.5mm higher than the bottom and the groove depth is 2.1mm. The air gap formed by the base 6 increases the thermal resistance to 0.25m 2 K / W measured data: After being filled with 90℃ hot water for 2 hours, the outer surface temperature is ≤48℃. It can effectively block the heat source when holding the edge, and the bottom is effectively protected in the event of a drop. BRIEF DESCRIPTION OF THE DRAWINGS
