A locking mechanism for locking an upper cover of a container to a side plate (2) of the container, the container (100) comprising a base (1), the upper cover (4) and the side plate, the upper cover (4) being provided with an edge guard; the locking mechanism comprises a lock hole (522) formed on the exterior of at least one of the side plate (2) and a groove (5411) formed on the upper cover; an end of the locking element (50) is mounted in the groove (5411); the other end of the locking element (50) is provided with a lock (5021); the lock (5021) passes through the edge guard and extends into the locking hole in a direction perpendicular to a direction of the side plate (2) to securely lock the upper cover (4) to the side plate (2); the driving element (51) is mounted in the groove (5411) and used to return element is mounted in the groove (5411) and used to return the mechanism, transportation and storage cost are reduced, and labor of operators is saved.

In one embodiment, a lid structure with latches is configured for sealing use with container vessels of different materials having differing manufacturing dimensional tolerances, such plastic vessels and glass vessels. Another feature of a lid and vessel combination is the provision of a lid receptacle feature, configured to capture the base of a vessel in a stacking arrangement, without utilization of special features on the vessel base. A method of merchandising lids and vessels is described, wherein a lid is provided for separate purchase, a plurality of vessels of different materials is provided for separate purchase which are configured to match to the lid.

According to an aspect of the invention, a latching mechanism/device is provided, as well as a method of maintaining a closed position between opposing first and second portions of a container. The latching mechanism includes a latch attached to the first portion and a latch keeper integrally molded to the second portion. The latch keeper includes an elongated keeper slot and a recessed pocket formed in the keeper slot, such that when at least a portion of the latch is received within the recessed pocket, the container is closed and/or sealed.

Disclosed is a container lid for vacuum sealing which generates negative pressure in the internal space of a container, which is provided by covering the open upper part of a container main body, and seals same. An annular packing is mounted so as to go around the inner surface of a lid main body, and a check valve is mounted in the inner part of the outer surface of the lid main body. The check valve generates negative pressure in the internal space of the container by allowing air inside the container to flow to the outside but preventing outside air from flowing into the container when a pressure difference occurs between the inside and outside of the container. A plurality of self catching protrusions are provided respectively at a plurality of points on the edges of the lid main body, and a plurality of locking members are mounted respectively and pivotably in sections adjacent to the plurality of self catching protrusions. Each locking member comprises: self-locking protrusions which are press-fitted and coupled to the self catching protrusions in a closed state so that the locking members are not released; and main body-locking protrusions which prevent the container lid from being taken off from the container main body by being caught by the circumference of the opening part of the container main body or a main body catching protrusion, even if the container lid rises due to the expansion of the packing as a result of a decrease in the negative pressure generated inside the container.

A case comprises a case body, a case cover, and a snap-fitting assembly comprising a snap-fitting member and a connecting member for fastening the case cover and the case body. The connecting member comprises a first end and a second end opposite to each other. The first end of the connecting member is rotatably connected to one of the case body and the case cover. The other one of the case body and the case cover is provided with a snapping block. The second end of the connecting member is rotatably connected to the snap-fitting member. The snap-fitting member comprises a snapping part configured to be snapped with the snapping block.

A reclosable elastomeric fastener and method for sealing storage and serving containers using same. The fastener consists of two complementary elastomeric profiles, having male and female interlocking elements, which extend around the periphery of the lid and container components of a storage receptacle. The reclosable fastener forms a water-resistant seal when the male and female elements of the complementary profiles are mutually occluded.

A replaceable latch and a container including the same are disclosed. The latch can include a latch plate; at least one clip, at least one projection for engaging a rod in the at least one clip; and a locking protrusion extending from the latch plate. Each clip can include a rod seat for rotatably engaging a rod. The container can include a first portion, comprising a mounting rod; a replaceable latch for rotatably coupling to the mounting rod; and a second portion, comprising a latch catch.
