Embodiment Construction

[0021] Such as Figure 1-5 As shown, a plastic container structure 1 according to an embodiment of the present invention includes a lid 2 , a gasket 3 and a container 4 . The lid 2 is configured to be connected to the container 4 by movement of the lid 2 along the joining direction D relative to the container 4 to close the container 4 . The container 4 has an opening defined by a peripheral edge 5 having a peripheral seat 6 for receiving the gasket 3 . Furthermore, the lid 2 has a peripheral wall 7 configured to surround the peripheral flange 5 of the container 4 . The seat 6 is arranged on the outer side of the flange 5 of the container 4 opposite to the peripheral wall 7 of the cover 2, and the seat 6 and the peripheral wall 7 of the cover 2 are configured such that the gasket 3 is compressed between the peripheral wall 7 of the cover 2 and the container 4. Between seats 6.

[0022] The plastic material chosen for the container 4 and lid 2 is a thermoplastic material sui...

Abstract

The present invention relates to a plastic container structure (1) comprising a lid (2), a gasket (3), and a container (4). The lid (2) is configured to be attached to the container (4) to close it by movement of the lid (2) relative to the container (4) along an engagement direction (D). The container (4) has an opening defined by a circumferential flange (5) having a circumferential seat (6) for receiving the gasket (3). Also, the lid (2) has a circumferential wall (7) configured to surround the circumferential flange (5) of the container (4). The seat (6) is provided on the outside of the flange (5) of the container (4) opposite the circumferential wall (7) of the lid (2) and the seat (6) and the circumferential wall (7) of the lid (2) are configured such that the gasket (3) is compressed between the circumferential wall (7) of the lid (2) and the seat (6) of the container (4). The circumferential flange (5) of the container and / or the wall (7) of the lid (2) are convex in a plane substantially perpendicular to the engagement direction (D).

Description

technical field [0001] The present invention relates to a waterproof plastic box suitable for injection molding. More particularly, the present invention relates to a joint structure for waterproof joints between plastic parts, and in particular, to a waterproof plastic case suitable for containing electronic components. Background technique [0002] Plastic containers with removable lids are well known in the art and can be used to store and protect eg objects or cooked food. Plastic containers are generally not airtight and are therefore not suitable for protecting sensitive electronic equipment. Another problem with known plastic containers is that they must be designed in such a way that they can be injection molded. Therefore, a plastic container that can be manufactured by injection molding and is airtight would be advantageous. Yet another problem is how to design plastic containers that can be manufactured with cheap molds with high tolerances, less wear on the mo...
