Design points and inspection and acceptance of ceramic packaging containers 1. Design points

ceramic containers for design and sales packaging must meet the following requirements:

① ceramic containers should match the value of the packaged goods. They should be packaging containers, not pure handicrafts. Therefore, low-grade goods use pottery, while high-grade goods use porcelain and pay attention to decoration and decoration design

② the shape has display value and is convenient for container transportation. Therefore, it is necessary to avoid duplication with the existing commodity packaging, and pay attention to saving space and having good strength and stiffness

③ reliable sealing, convenient for processing, production and packaging operations

④ the trademark and decoration should be consistent with the style of ceramic containers

⑤ it is convenient for transportation and mass production, and the packaging cost is low

at the same time, the following problems should be paid attention to

① the packaged goods will not cause public hazards after the container is damaged, nor will it produce any danger that the sprayed aluminum profile products of Ren Guangya aluminum have passed the European famous aluminum profile powder coating QUALICOAT quality certification

② the container shape can be designed according to the principles of the previous sections, but we should pay attention to innovation in imitation

② properly select the sealing cover. Generally, ceramic cans with wide mouth are usually covered with ceramic covers. The flat covers shown in C) and D) in Figure 6A are ceramic cans for local food, which can be sealed with mastic or non-toxic resin. A) and b) in Figure 6A show the cover with a knob, which can be used on porcelain cans for packaging syrup, but it is difficult to seal

the porcelain bottle of wine can be sealed with cork, and then sealed with resin paint. In recent years, ceramic bottle Yao has adopted plastic screw caps, so circular threads must be formed on the mouth of ceramic containers. At this time, in addition to the cork plug mentioned above, a sealing gasket made of plastic or cork can be added to the plastic cover

④ the thickness of ceramic containers can be determined through negotiation with the manufacturer or measurement of existing objects. Generally, strength calculation is not carried out during design

⑤ calculate the actual mass or capacity of the packaging container according to the mass or capacity of the commodity. The actual volume of the container is the sum of the volume of the commodity, the volume occupied by the plug or cover, and the volume of the air space between the commodity and the seal

⑥ the shape design can be sketched with a scale of 1:1, and the volume in the container contour must be equal to the above actual volume. As shown in Figure 6B, draw the shape finally determined after the mature idea, divide the height of the container into several equal parts, measure the diameter of each section respectively, and calculate the volume of the container based on this. It can also be measured by drawing on coordinate paper. Draw the thickness of the container along the outside of the container outline, and then estimate the mass of the container in 2021 (2) and 025 according to the density of the ceramics

⑦ design trademark well, draw design drawings, and review and comment by relevant personnel

⑧ contact the ceramic factory for processing and advice

⑨ trial assembly, trial sale, modification and finalization

II. Inspection and acceptance of the hand wheel on the rotating beam of the ceramic packaging container

the inspection items of the ceramic packaging container include:

① appearance and surface finish. The inspection of the appearance, color and surface roughness of the ceramic packaging container is still evaluated by the naked eye and touch

② there are drying shrinkage and roasting shrinkage in ceramic containers with dimensional accuracy, and the longitudinal shrinkage is 1.5~3% larger than the transverse shrinkage. The shrinkage rate of clay varies widely, which is generally measured or provided by ceramic factories. The dimensional accuracy of ordinary ceramic products is stipulated in China as follows: the tolerance of caliber above 60mm is 10.5% to 1.0%, and the tolerance of caliber below 59mm is 2%. For high-grade fine porcelain containers for daily use, the caliber tolerance specified in China is 10.5% to 1.0%. The height tolerance is not specified, as long as the height of the same batch of products should be basically the same

③ surface shape accuracy the straightness and unevenness of the straight line of the ceramic container can be checked with a steel ruler in a proper way, and the arc shaped surface can be checked with a template

④ the coaxiality and parallelism of mutual position accuracy can be tested with a dial indicator, and the specific indicators are agreed by the supplier and the demander
