A weighing hopper includes a tubular main body having an upper end opening constituting a loading port and a lower end opening constituting a dispensing port and a gate provided on the main body swingably in such a way that the gate opens/closes the dispensing port, wherein the main body and the gate are formed by bending components after joining the components by diffusion.
1. A container comprising:
a main body, at least an inner surface of which is used to deliver an object, wherein
the main body is formed by bending components after joining the components by diffusion bonding, wherein
at least a part of a portion joined by the diffusion bonding is bent,
the part being bent has higher Vickers hardness than a remaining part of the portion joined by the diffusion bonding, and
an interface between the components has disappeared at the portion joined by the diffusion bonding.
2. The container according to claim 1 , wherein
the main body is formed in a tubular shape of which upper end opening constitutes a loading port and a lower end opening constitutes a dispensing port,
the container further comprising an opening/closing member provided on the main body swingably in a way that the opening/closing member opens/closes the dispensing port, and
the main body and the opening/closing member are formed by bending their components after joining their components by diffusion bonding.
3. The container according to claim 2 , wherein at least one of the main body and the opening/closing member is formed by bending the components after joining components by diffusion bonding and embossing a portion to form an inner surface of the container.
4. The container according to claim 2 , wherein at least one of the main body and the opening/closing member is formed by embossing a portion to form an inner surface of the container after joining the components by diffusion bonding and bending the components.
5. The container according to claim 2 , wherein at least one of the main body and the opening/closing member is made of stainless.
6. The container according to claim 3 , wherein at least one of the main body and the opening/closing member is made of stainless.
7. The container according to claim 4 , wherein at least one of the main body and the opening/closing member is made of stainless.
8. The container according to claim 1 , wherein at least a part of a portion joined by the diffusion bonding is bent by the bending.
