Proposed is a press-fit structure for sealing fastened portions while detachably fastening a first member and a second member to each other, the improved press-fit structure including: a male seal formed to protrude to a predetermined length on the first member, a female seal formed on the second member in a groove shape corresponding to the length of the male seal, and configured such that the male seal is press-fitted thereinto; and air discharge portions formed in portions of the male seal, and configured to provide discharge paths for air inside the female seal during the process of press-fitting the male seal.

A storage and transportation device, which relates to the technical field of storage and transportation apparatuses are disclosed. The storage and transportation device comprises a cover, a supporting plate and a sealant. The supporting plate covers an opening of the cover to form a space for accommodating an item to be transported. The storage and transportation device further comprises a first sealant groove and a second sealant groove arranged at a sealed junction between the cover and the supporting plate, the sealant is contained in each of the first sealant groove and the second sealant groove, and the two parts of the sealant are connected.

The present disclosure relates generally to containers and container lids. In at least one embodiment, the disclosed containers and container lids provide a liquid-tight seal with the inclusion of a separately attached ring that generally eliminates material-trapping seams. For example, in certain embodiments, a container and a container ring for attaching to the rim of the container is disclosed. In these embodiments, the container ring attaches to the rim of the container such that a liquid-tight vertical seal is formed, thereby reducing or eliminating material-trapping seams.

An embodiment relates to a press-fit structure for sealing fastened portions while detachably fastening a first member and a second member to each other, the improved press-fit structure including: a male seal formed to protrude to a predetermined length on the first member; a female seal formed on the second member in a groove shape corresponding to the length of the male seal, and configured such that the male seal is press-fitted thereinto; and air discharge portions formed in portions of the male seal, and configured to provide discharge paths for air inside the female seal during the process of press-fitting the male seal.
