Tube container patent

  • February 24, 2021


Hello. This is Hiro.
I bought wasabi in a tube container, made and sold by S&B Foods Inc., with the patent number displayed.

When you open the cap, you can see that the shape around the screw part of the container and the inside of the cap have some designs to them.

Thanks to the locking part, it is difficult to loosen when the cap is closed, and it will not open without permission. Also, thanks to the screw part divided into four in the circumferential direction, it can be easily opened with a slight twist of the cap. In addition, the vertical grooves make it easy to crush the tip of the container and squeeze out the wasabi.

By the way, the problem to be solved by the invention of Japanese Patent No. 660532 is, “Compared to the conventional invention, the impact of outward convex of the container body constituting the loosening part just before overcoming the inward part of the lid is to be made stronger and the force required for this is to be increased. Furthermore, the distance to be overcome is shortened, thereby making the clearer feeling when the lid is closed.” Certainly, when you close the cap, you can clearly feel that it is closed.
I am surprised that such tube containers, which have been around for a long time, have been improved and made easier to use.
