Printing Column] Follow the mystery of cartons and cracks!

I was contacted by the company. This is a tough one. The photo shows that it is indeed cracked. I immediately took out a keep sample from our company and tried to wake it up.

Oh, that's not a crack.

We ran out of keep samples and none of the cracks occurred and we do not know what condition they are in. Since we could not determine the situation without seeing the actual product, we asked the sales representative to send us the customer's box in which cracks had occurred ASAP. When we received the product from the customer, we found that the bottom corner of the one-touch case had been torn diagonally upward. In addition, the ruled line around the crack is bulging outward.

Since the ruled lines were bulging outward, I thought something was caught somewhere when assembling, and tried various methods such as pushing and twisting various places to wake it up, but could not reproduce the problem. At any rate, I asked them to return the product once it was cracked and unusable.

Then, with the returned boxes, we try to put the boxes together.

Hey, the phenomenon that the customer pointed out doesn't occur? Why?

Nearly 50% of the boxes are broken at the customer, but Marushin cannot reproduce a single one.

Sales asked us to test as many boxes as we could use, so we also prepared 720 ml bottles for a reproduction test.
I was able to reproduce it in one shot when I verified that if the bottles were inserted with the one-touch box not assembled properly (not locked), the force might be applied to the outside of the box. After that, I tried about 10 bottles, and the same phenomenon was observed in all of them. This was a new discovery. After that, I explained to the sales staff that I could solve the problem by inserting the bottles after assembling them.

It was a new discovery that one-touch decorative boxes can tear from the bottom to the sides if the product is not placed in the box after the box is completely assembled. We are grateful to the customer for this new discovery, while thinking of a way to prevent cracking even in that condition.
