Since canned fruit and fruit juice drinks are to be made as an industry, it is natural to consider the issue of packaging. As a result, Marin, a half-baked "big designer", naturally wanted to design the packaging shape. It can't be said that the design is plagiarized, and the design of later generations is plagiarized.

However, Marin remembered that many of the cans that seemed to be in later generations were packaged in aluminum boxes and sealed with tinplate. This kind of thing Marin can't imitate and copy, the main thing is that he doesn't have aluminum cans. In the 21st century, in order to promote sales, many merchants specially designed canned bottles in the style of water cups. As a result, canned food has become more popular because it can be used as a drinking cup after eating canned food. Therefore, this line of thinking is very worthy of reference.

As a result, Marin drew the popular style of water cups and bottles. Then, a simple wooden hoop sleeve was added to the outside of the bottle, with an inverted "L" wooden handle sticking out for the user to hold. In this way, the buyer can use the canned bottle as a water cup after eating the can. The presence of wooden handles allows the user to avoid being burned by the boiling water in the cup.

In fact, the bottle body is still very "designed", and it can be copied from the appearance of later generations. But the design of the bottle mouth part is difficult for Marlin.

The problem was mainly in the lid, and in this era, the European bottle was still dominated by wooden stoppers, rather than the thread-meshing twist cap that was popular in later generations.

Marin wanted to design a thread-meshing twist cap for later generations, but after talking to the craftsmen, he decided to abandon the idea. Why? It's not that the craftsmen can't make the thread-meshing twist cap, it's that it's too difficult to manufacture.

In this era, the manufacture of yin and yang threads for glass bottles and caps is not made by machine, but by hand. Only craftsmen with high returns can create a yin and yang thread with a high degree of fit, so that the air closure of the cap can meet the standard. If a random worker comes and carves the yin and yang threads by hand, it is likely that he will not meet the requirements of breath-holding. In this way, a bottle of can is scrapped.

If you ask a master to create yin and yang threads by hand, then the output will be very low and the cost will be high. In this way, it is not cost-effective.

Marin reluctantly gave up the design of the thread mesh twist cap, in fact, there is no professional machine to make it these days. In his previous life, he was not engaged in industry, and he did not know how to make the threads of bottles and caps, so he could only give up with regret.

Well, the rest is left with a stopper design......

Cork stoppers and sealing wax, such a sealing method is very simple, any temporary worker with general skills can be competent for the work of air-tight sealing. But the biggest problem is that cork doesn't do it!

Cork trees in Portugal take up to 25 years to be harvested and are currently produced in limited quantities. Marin's plan is to make canned fruit into a national food, and the amount is very large, and Portugal's production is really not enough.

So, Marin had to think of replacing the cork with natural rubber. Natural rubber stopper, Marin first thought of the rubber stopper on the saline bottle when he was a child.

That is the memory of a generation, before Marin crossed, saline had been used in plastic bottles or even plastic bags. But in the 90s, hospitals hung water on people, all using glass bottles with rubber stoppers.

In addition to being used when hanging water, Marlin also used this saline bottle as a hot water bottle when he had cold hands in winter when he was a child. The normal saline bottle in the hospital was discarded when it ran out, and many people could take the normal saline bottle that they used to hang water back after hanging water.

The saline bottle with the rubber stopper is super sealed, even if it has been poked before, the hole will be closed after the needle is removed, and the cork will not leak.

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

The Yangtze River basin is a very embarrassing place, the winter here is not as cold as in the north, so there is generally no heating, and there are no ondols in the countryside. But in winter, when the temperature is below zero, it is also very cold, and it is wet and cold. Therefore, when I was in the nineties, when I went to bed at night, Marin often used a saline bottle filled with hot water to put it into my warm quilt before falling asleep. It wasn't until the 21st century, with the advent of hot water bottles made of rubber, that the saline bottle was eliminated.

With this experience, Marlin has a very deep memory of the rubber stopper of the saline bottle. Therefore, he "designed" the drawings of the saline bottle without thinking about it...... That's what he grew up with......

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

The mouth of the bottle is too small to fit the pineapple slices. Even if you put it in, it's hard to take it out and eat it. What the? You said you chopped the pineapple and put it in? It's not that it can't be done, but it loses the original intention of canned fruit - people are here to eat fruit, not fruit pomace......

Therefore, canned fruit bottles must not be designed with the neck of a saline bottle. However, fruit juice can be packaged in this bottle......

So, with a stroke of the pen, Marlin decided on the packaging of the fruit juice - using a saline bottle......

Then, Marin had in his mind the scene of the citizens of the North Sea Kingdom drinking juice with hanging water bottles...... Hehe, Marin is happy when he thinks about it......

Of course, this pleasure for him can only be enjoyed by himself. No one else has ever seen a saline bottle with hanging water, so I can't laugh at all......

……

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

Marlin would like to continue with the saline bottle stopper, which only fits the mouth of the vial. Once the bottle mouth is large, the soft rubber is squeezed and easily deformed, resulting in leakage.

"What to do?" Marlin was a little scratched.

So, he ran to the cannery in search of inspiration......

There are also canned food in Beihai now, for example, there is a canned sauerkraut fish processing plant in Beihai. When sealing steamed sauerkraut fish, workers often choose a cork that is a little larger than the mouth of the bottle. In this way, after the bottle is stuffed, it can ensure that the breath holding is good enough. And those cork stoppers that are not of sufficient size are considered defective. Either they are eliminated or they are pooled and taken elsewhere to be processed into smaller stoppers.

And in the canning and sealing workshop, a water cup from the workshop leader aroused his strong interest......

The person in charge of this workshop seems to be a little good at rubbing the oil of the public, for example, the cup he drinks from looks like a canned bottle. But the difference is that the canned bottle he uses to drink water seems to be a discarded product......

There is nothing wrong with the glass itself, but the stopper seems to be an undersized cork that has been eliminated. But Hans, the head of the workshop, had a good idea - he put a cloth on the undersized cork. The cork then plugs the bottle and keeps his glass from leaking.

Of course, this can only guarantee that there will be no water leakage, but not air leakage. After all, cloth doesn't have the good breath-holding properties of cork.

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

"Stopper...... Wrapping ...... Good idea......" Marin cried out happily.

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

He remembers that when he was a child, some water cups, because of the poor processing accuracy, in order not to leak, many manufacturers put rubber leather rings in the bottle caps.

In the same way, a rubber holster around the cork can also be used to prevent leakage and seal air.

And, it occurred to him that if the cork was covered with a rubber holster, then the cork would not necessarily need to be made of expensive and scarce cork. He can use a regular cork of about the same size, and then put a rubber holster on the ordinary cork. In this way, it is also possible to ensure that the air is closed and leak-proof. In addition, it successfully avoided the weakness that the rubber stopper could not be made bigger.

Thinking of this, Marin was extremely excited. With a rubber holster, he doesn't have to worry about going to Portugal to find cork. The growth cycle of the pit daddy's cork is 25 years. Moreover, after the bark of the cork tree has been peeled, it is not until another nine to ten years before it can be peeled again (cork is made from the bark of the cork tree).

Marin suddenly had a very magical rhythm in his mind to Eason Chan's "Ten Years" - "Ten years later, I will peel the bark again, peel your bark ......"

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

Marlin didn't think about the cork anymore, but continued to work on his rubber cork. And because there will definitely be a great demand for rubber stoppers and rubber stoppers in the future, Marin decided to expand the planting area of rubber trees again......
