A waterproof container is disclosed. The container can include first shell and a second shell; a first rim extending around the first shell; a second rim extending around the second shell; and a latch for securing the first shell to the second shell and defining an enclosed storage volume in a mated position. The first shell can include a grip projection adapted for opening the container from a mated position. The latch defines a latch recess adapted for receiving the grip projection when the latch secures the first shell to the second shell in the mated position. The second rim can include a continuous recess, having a pair of continuous sides and a seal ridge between, but spaced apart from, the continuous sides, while the first rim can include inner and outer continuous sealing ridges that fit over the seal ridge and between the continuous sides.

A tamper-evident container generally includes a tray having an opening with a step section formed around the opening and including a first protrusion section that is provided with a first coupling unit with a first perforation line formed therebetween. The first coupling unit includes a coupling trough. A cover includes a concave groove having a bottom and an outside surface engageable with the step section to close the opening. The cover includes a second protrusion section and a second coupling unit between which a second perforation line is formed and projecting beyond the first perforation line. The second coupling unit has a coupling member receivable in and engageable with the coupling trough. Tearing off the first and second perforation lines allows the first and second coupling units to detach from the tray and the cover, respectively with the second protrusion section projecting outside the tray for easy gripping.
