Container

A container comprising:

• a port part;
• a barrel part continuous with the port part;
• a bottom part provided on a side opposite to the port part via the barrel part;
• and
• a depression-protrusion structure configured to develop a lotus effect on at least an inner surface of the barrel part,
• wherein, when a direction passing through the port part and the bottom part is defined as a height direction, a width in a direction intersecting the height direction of a protruded part of the depression-protrusion structure at a certain position in the height direction is less than a width in the direction intersecting the height direction of the protruded part of the depression-protrusion structure at a position on a bottom part side relative to the certain position in the height direction, or a width in the direction intersecting the height direction of a depressed part of the depression-protrusion structure at a certain position in the height direction is greater than a width in the direction intersecting the height direction of the depressed part of the depression-protrusion structure at a position on the bottom part side relative to the certain position in the height direction.

A container comprising:

• a port part;
• a barrel part continuous with the port part;
• a bottom part provided on a side opposite to the port part via the barrel part;
• and
• a depression-protrusion structure configured to develop a lotus effect on at least an inner surface of the barrel part,
• wherein a width of a protruded part at a position on a port part side relative to a bottom part side of the depression-protrusion structure is different from a width of the protruded part at a position on the bottom part side relative to the port part side of the depression-protrusion structure, or a width of a depressed part at a position on the port part side relative to the bottom part side of the depression-protrusion structure is different from a width of the depressed part at a position on the bottom part side relative to the port part side of the depression-protrusion structure.

A container comprising:

• a port part;
• a barrel part continuous with the port part;
• a bottom part provided on a side opposite to the port part via the barrel part;
• and
• a depression-protrusion structure configured to develop a lotus effect on inner surfaces of the barrel part and the bottom part,
• wherein, when a direction passing through the port part and the bottom part is defined as a height direction, the depression-protrusion structure of the barrel part is configured to include, in a direction intersecting the height direction, a plurality of protruded parts or depressed parts arranged in a stripe pattern extending in the height direction, and the depression-protrusion structure of the bottom part is configured to include a plurality of protruded parts or depressed parts separate from one another arranged two-dimensionally.
