Cheeseburger in a cane

What could be the best way to protect the condition of cheeseburger which not only western countries but all the people around the World love to eat? The company named `Katadyn/Trekking-Mahizeiten` invented a really useful idea that keeping the cheeseburger in a can. It is very good idea since it keeps the condition of the cheeseburger and it is very easy to carry around.
In these days, a lot of people go to trip or vacation from schools, companies, or as a family trip. And when you go to those kind of trips, you also have to carry your own food to save money (because all those food at the sightseeing places are really expensive). A lot of people who go to trip would want to take food that they like the most. And cheeseburger would be one of the most favorite food to a lot of people who at least tried it. But how could people carry these burgers for a long time without making it rotten? `Katadyn company invented a new fresh idea that you can carry this kind of cheeseburgers around to trip or anyplace without worrying about it being rotten. This is really nice idea since that you can carry cheeseburger easily anywhere you want because it is not even big capacity. Due to these useful factors, I think a lot of people would love to buy these products. But one of the cons about this product is that people might just think that "Why would I bother to buy that canned burger, if I can just buy it from mc. Donalds". But this is absolutely true, I think they have to prove themselves by showing better pros such as that they have better nutrients or whatever that would satisfy customers.
As I kept saying, this product is really useful since it ensure the condition of the burger and also it is really easy to carry but the thing is it is not good enough product to attract people who buy from the Mc.Donalds. So it might have to try more options to it. Other than that, it is great!!
