A leak-proof, interlocking, stackable travel container assembly has a sealing plug and a plurality of travel containers. The sealing plug is designed to create an airtight seal when positioned within an opening. In order to do so, the sealing plug has a first sealing ring, a second sealing ring and a lip. Each of the plurality of travel containers has a neck portion, an opening, a body portion and a base portion. The opening perpendicularly traverses into the neck portion allowing an user to place and remove items within the travel container. When required, the sealing plug is placed within the opening. Next, a protective cap is used to surround the sealing plug. If multiple travel containers are to be used, a base interlocking mechanism and a neck interlocking mechanism are used for interlocking each of the plurality of travel containers.

The packaging box in the disclosure, which is a packaging box for packaging an object, includes a tubular box body having a first opening in an upper surface thereof, and a lid body detachably attached to the first opening to cover the first opening. The box body has a first turned-back section that is provided in at least one part of a peripheral edge of the first opening and turned back so as to be overlapped with an inner surface of the box body. The lid body has an insertion section that is provided in at least one part of a peripheral edge of the lid body and is to be inserted between the first turned-back section and the inner surface of the box body when the lid body is attached to the first opening.

A ventilated plug for a shipping, display, or other tube is provided. The ventilated plug is configured to frictionally connect to the tube to provide a ventilated interior of the tube. The plug may be particularly advantageous for transport and display of living organisms.

The present disclosure provides a container sealing plug. The container sealing plug including a plug body. The plug body is configured to seal a receiving opening of a container. The plug body includes a sealing part. The sealing part is configured to seal the receiving opening of the container. The sealing part is provided with a flexible sealing ring. The sealing ring is configured to press an inner wall that seals the receiving opening of the sealed container. A user can place food, liquid, or other objects into the container through the receiving opening of the container, and then seal the receiving opening of the container through the plug body. When the flexible sealing ring of the plug body is inserted into the receiving opening of the container, the inner wall of the receiving opening presses the flexible sealing ring.
