What is the content of ten questions and ten answers when buying a water cup? (two)

In the last article, the editor summarized five questions and five answers, and today we will continue the following five questions and five answers. What questions do you have when buying a water cup?

6. Does the thermos cup have a shelf life?

Strictly speaking, the thermos cup has a shelf life, but due to the material properties and material quality, many thermos cups with good quality can be used for a long time.However, according to the requirements of the national standard, the shelf life varies from 3 to 5 years for the corresponding materials.

7. Why is there no production date on the purchased water cup?

Due to the characteristics of long shelf life and long service life of the water cup, the market supervision department does not require the water cup manufacturer to mark the production date before leaving the factory.You may be confused.Since the water cup has a shelf life, but there is no production date on the production package, will you buy a water cup that has expired the shelf life?Can this water cup be used?

The water cup itself belongs to FMCG, and the production enterprises often make strict production plans during production.Once the problem of product backlog occurs, the inventory will usually be digested in the way of low price.However, it is not ruled out that there are many years of overstocked water cups in some channels or in some factories. It is difficult for consumers to judge when purchasing such cups.Usually, these cups will be cleaned and wiped again through the production line, but this situation is still rare, and we need not worry too much.

8. After washing the newly purchased water cup several times, it is found that there are still impurities floating in the water. Can this water cup be used?

This is often caused by the poor sand blasting process of the water cup, resulting in insufficient adhesion of the coating after sand blasting.In this case, it is recommended to vigorously clean the inner wall of the water cup for 2-3 times.If this phenomenon is found after cleaning, it is not recommended to use it, and return and replace the goods immediately.

9. Is the metal titanium water cup really as advertised?

A reader once left a message asking questions similar to the title.This question is not easy to answer. Now that you ask it, you are suspicious.Propaganda will certainly beautify and expand the effect, which is equivalent to seeing all kinds of advertisements. Do you really believe that what is said in the advertisements is true?

10. How to judge the quality of the cup?

Look at the material, the workmanship and the rationality of the design.Prices vary from person to person, but what is not expensive must be the best. Of course, the lower the price, the higher the cost performance.

At the very least, a good water cup should be made with enough work and materials.

Take the heat preservation cup as an example. In order to ensure the heat preservation effect, the normal eye is that the vacuum duration is 6 hours during the vacuum process. However, some factories will shorten the vacuum duration in order to improve efficiency, resulting in poor heat preservation effect, especially after a period of use, which is theft.

It is better to understand the material reduction. It is clearly said that the internal 316 and external 304 stainless steel are sold, but the actual production is changed to the internal 304 stainless steel and external 201 stainless steel, in order to save costs and obtain greater profits, which is material reduction.
