Ceramic packaging container design and inspection

First, the design points

Ceramic containers designed for sales packaging must meet the following requirements:

1 The ceramic container should be compatible with the value of the packaged goods. It should be a packaging container, not pure craftwork. Therefore, pottery is used for low-grade goods, while porcelain is used for high-end goods and attention is paid to decoration and interior design.

2 Modeling has display value and is convenient for container transportation. For this reason, it is necessary to avoid duplication with existing product packaging, and pay attention to space saving and have good strength and rigidity.

3 reliable sealing, easy processing and production and packaging operations.

4 Trademarks and decorations should be consistent with the style of ceramic containers

5 Easy to transport and mass production, low packaging costs.

At the same time should pay attention to the following questions;

1 The packaged product will not cause public hazard after the container is damaged, nor will it cause any danger.

2 The shape of the container can be designed in accordance with the principles of the preceding sections, but attention should be paid to innovation in imitation.

2 Select the sealing cap properly. Generally, a wide-mouth ceramic jar has a multi-purpose ceramic lid. The flat lid shown in Figs. 6a, c) and d) is a native food ceramic jar lid, which can be sealed with cement or non-toxic resin. Figure 6a, a), b) shows the lid with the handle, can be used to package porcelain cans such as syrup, but more difficult to seal.

Porcelain bottles for packaging wine can be sealed with cork stoppers and the mouth is sealed with resin paint. In recent years, ceramic bottles have adopted plastic screw caps. Therefore, circular threads must be formed on the ceramic containers. At this time, besides the aforementioned cork stopper, a seal made of plastic or cork may be added to the plastic cover.

4 The thickness of the ceramic container can be determined by the manufacturer and determined by measuring or measuring existing material. The strength calculation is generally not performed at design time.

5 Calculate the actual quality or capacity of the packaging container according to the quality or capacity of the product. The actual volume of the container is the sum of the product volume, the volume occupied by the plug or lid, and the volume of the air space between the product and the seal.

6 Modeling The sketch can be drawn in a 1:1 ratio. The volume in the outline of the container must be equal to the actual volume mentioned above. As shown in Fig. 6b, the shape of the shape determined to be mature is drawn and the height of the container is divided into several equal parts. The diameter of each segment is measured by the well and the volume of the container is calculated accordingly. It can also be plotted on the coordinate paper. The thickness of the container is plotted along the outside of the outline of the container, and the quality of the container is estimated based on the density of the ceramic.

7 Design trademark wells to draw design drawings and review and comment by related personnel.

8 Contact the ceramics factory for processing and ask for opinions.

9 test equipment, test sales, modification and finalization.

Second, ceramic packaging capacity inspection and acceptance

Ceramic packaging container inspection items include:

1 Appearance and surface finish Inspection of the appearance, color, and surface roughness of ceramic packaging containers is still evaluated by visual inspection and touch.

2 dimensional accuracy

The ceramic container has drying shrinkage and roasting shrinkage, and the longitudinal shrinkage is 1.5-3% larger than the transverse shrinkage. The shrinkage of the clay material has a wide range of variation. Generally, the ceramics factory determines or provides data. The dimensional accuracy of ordinary ceramic products, our country provides as follows: the tolerance of the diameter above 60mm is 0.15%~1.0%, and the tolerance of the diameter below 59mm is 2% of the soil. Advanced fine porcelain containers for daily use, China's caliber diameter tolerance is from 1.5% to 1.0%. The height tolerance is not regulated, and only the height of the same batch of products should be basically the same.

3 Surface Shape Accuracy The straightness and unevenness of the straight surface of the ceramic container can be tested in an appropriate manner with a steel rule, and the arc shape surface is checked with a template.

4 mutual position accuracy Concentricity, parallelism can be used dial indicator test, specific indicators agreed by the supply and demand sides.
