Chapter 1525： Cover or plug? This is a problem ...

Since canned fruit and fruit juice beverages are to be treated as an industry, it is natural to consider packaging issues. Therefore, Marin, a semi-hanging "big designer", will naturally design the packaging shape. Nor can we say design, but plagiarism, plagiarism of later designs.

However, Marin remembers that many of the tins that appear to be hereafter are packed in aluminum boxes and tinplate sealed. Malin can't imitate and copy this kind of stuff, mainly because he doesn't have aluminum cans. In the 21st century, in the 21st century, many merchants specially designed canned bottles as water glasses in order to promote sales. In this way, the canned bottle can be used as a drinking cup after eating the canned food, making the canned food more popular. Therefore, this idea is worth learning from.

Therefore, Marin drew a cup-style can that was very popular in later generations. Then, a simple wooden hoop was added to the bottle, and an inverted "L" wooden handle was extended to let the user hold it. In this way, the buyer can use the canned bottle as a drinking glass after eating the canned food. The presence of the wooden handle allows the user to avoid being scalded by the boiling water in the cup.

In fact, the bottle is still very "designed", just copy the shape of later generations. However, the design of the bottle mouth part made Marin difficult.

The problem is mainly on the lid. In this era, European bottles are mainly popular with corks, rather than the threaded twisting cap that is popular in later generations.

Marin wanted to design a threaded screw cap for later generations, but after talking with the craftsmen, he gave up the idea decisively. Why? It is not that the craftsmen cannot manufacture threaded screw caps, but it is too difficult to manufacture.

In this era, the production of male and female threads for glass bottles and caps was not made by machines, but by hand. Only a craftsman with a high profit can create a male and female thread with a high degree of fit, so that the closure of the bottle cap can reach the standard. If you come to a worker and engrave the male and female threads by hand, you may not be able to meet the requirement of breathing. In this way, a bottle of canned food is scrapped.

If you ask the master to manually create the male and female threads, the output will be very low and the cost will be high. In this way, it is very cost-effective.

Marin reluctantly gave up the design of the threaded screw cap. In fact, there is no professional machine to make this year. He didn't work in industry in his previous life. He didn't know how to make the threads of bottles and caps, so he only regretted giving up.

Then, the rest can only be designed with corks ...

Cork stopper plus sealing wax, this kind of packaging method is very simple, any casual worker with general skills can do the job of air-tight packaging. But the biggest problem is-cork doesn't do it!

Portuguese cork trees take 25 years to grow and are currently harvested. Marin's plan is to make canned fruits into national food. The amount is large, and the production in Portugal is really not enough.

Therefore, Marin can only think of replacing cork with natural rubber. Natural rubber stopper, Marin first thought of the rubber stopper on the saline bottle when he was hanging water as a child.

That's the memory of a generation. Before Marin passed through, the saline had been used in plastic bottles or even plastic bags. But in the 1990s, hospitals hung water, all using glass bottles with rubber stoppers.

In addition to being used when hanging water, Marin was cold in winter when he was a child, and also used this saline bottle as a hot water bottle. The saline bottle in the hospital was used up and discarded. At that time, many people hung up the water, and it was possible to take back the saline bottle used to hang the water.

The saline bottle plugged with a rubber stopper has excellent sealing performance. Even if the hole was pierced to hang water, the hole will be closed after the needle is pulled out, and the bottle stopper will not leak.

Therefore, the saline bottle was used by many people as a hot water bottle for hand warming. Even when you sleep in winter, you can use it to warm your feet.

The Yangtze River Basin is a very embarrassing place. Winter is not as cold as in the north, so it is generally not equipped with heating, nor is it built in the countryside. But in winter when the temperature is below zero, it is also very cold, and it is wet and cold. So, in the ninety-nine years, when sleeping at night, Marin often put a saline bottle filled with hot water into my warm blanket first, and then I could fall asleep. Until the 21st century, with the advent of rubber hot water bottles, the saline bottle was eliminated.

With this experience, Marin has a deep memory for the rubber stopper of saline bottle. Therefore, he "designed" the drawings of the saline bottle without thinking ... that was the thing that accompanied him growing up ...

But after "designing" the saline bottle, Marin realized a problem-the mouth of the saline bottle was too small ...

The bottle mouth is too small to fit pineapple slices. Even if it is packed in, it is difficult to take out to eat. what? You said shred the pineapple and put it in? Not bad, but lost the original intention of canned fruit-people come to eat fruit, not eat fruit residue ...

Therefore, the canned fruit bottle must not use the saline bottle design. However, fruit juice can be packed in this bottle ...

So, Marin made a big stroke, and set the packaging of the fruit juice-just use a saline bottle ...

Then, in the mind of Marin, the scene of the citizens of the North Sea country using the water bottle to drink juice ... Hehe, Marin was euphoric when he thought of it ...

Of course, his fun can only be enjoyed by himself. No one else has ever seen a saline bottle hanging from water.

...

After the music was over, Marin could only continue to "design" the lid of the can. This time it was really designed, because there is nothing to refer to.

Marin wanted to continue to use the saline bottle stopper design, but the middle stopper is only suitable for the small bottle mouth. Once the bottle mouth is large, the soft rubber is squeezed and easily deformed, causing leakage.

"What should I do?" Marin was blind.

So he went to the cannery to find inspiration ...

The Beihai Kingdom also has canned food. For example, there is a canned fish processing factory in the North Sea. When sealing steamed sauerkraut fish, workers often choose corks that are larger than the bottle mouth. In this way, the air tightness can be ensured sufficiently after being stuffed into the bottle mouth. Cork stoppers that are insufficiently processed are considered defective. Either be eliminated, or be collected, taken elsewhere, and processed into smaller sized stoppers.

And in the can packaging workshop, a water cup of the head of the workshop aroused his strong interest ...

The person in charge of this workshop seems to be able to wipe the public oil, for example, his drinking cup looks like a can. But the difference is that the canned bottle he used to drink water seems to be a knockout ...

This water glass bottle is no problem in itself, but the stopper seems to have been eliminated as an undersized cork stopper. But the head of the workshop, Hans, was very smart-he breaded this undersized cork with a cloth. Then, the cork stopper can stop the bottle and make sure that his water cup is not leaking. After all, the fabric doesn't have the good air tightness of cork.

However, this approach gave Marin a great inspiration ...

"Corks ... wrapping ... good idea ..." Marin cried out happily.

Of course, he didn't think of wrapping the corks, but thought-since I can wrap the corks, why can't I wrap the corks with rubber skin?

He remembered that when he was a kid, he had some cups because of poor processing accuracy. In order to prevent water leakage, many manufacturers put rubber aprons in the bottle caps.

Similarly, putting a rubber holster around the cork can prevent air leakage.

Moreover, he suddenly thought that if a rubber holster was added to the cork, then the cork would not necessarily need expensive cork. He can use ordinary wooden plugs of similar size, and then put a rubber holster on the ordinary wooden plug. In this way, it is also possible to ensure that the gas is closed and leak-proof. Moreover, it has successfully avoided the weakness that the rubber stopper cannot be made bigger.

Thinking of this, Marin was very excited. With a rubber holster, he didn't have to worry about finding cork in Portugal. The pit father's cork has a growth cycle of 25 years. Moreover, after peeling the cork bark, it takes another nine to ten years to peel it again (cork is processed from the bark of the cork tree).

Marin's mind suddenly sounded the rhythm of Chen Yixun's "Ten Years"-"Ten years later, I will peel again, peel your bark ..."

"Specially, it takes another ten years to peel a skin, enough for me to plant a lot of rubber trees!"

Marin no longer thought about cork, but continued to engage in his rubber stopper. And because the future demand for rubber bottle stoppers and rubber bottle stopper holsters is definitely great, Marin decided to expand the planting area of ​​rubber trees again ...
