Canister for containing an active agent

Abstract

The present application concerns a canister (10) for containing an active agent, such as a desiccant agent, an oxygen scavenger, or a scented agent and for allowing the active agent to interact with the environment of the canister (10), such as absorbing moisture or oxygen, when the canister is closed. The canister comprises a canister body (12) having a peripheral body wall (11) defining an upper opening (13) for inserting the active agent into the canister body (12), and a non-removable snap-on cap (14) cooperating with the canister body (12) so as to close the upper opening (13), the cap (14) comprising a peripheral skirt (C5). The peripheral body wall (11) comprises a step (B2) formed between a first portion (B5) of the peripheral body wall (11) located adjacent to the upper opening (13) and a second portion (B6) of the peripheral body wall (11) located beneath the first portion (B5). The first portion (B5) is at least partially thinner than the second portion (B6) so as to form the step (B2), wherein an inner shape of the peripheral skirt (C5) and an outer shape of the first portion (B5) of the peripheral body wall (11) are adapted to form a snap-on fit between the cap (14) and the canister body (12) wherein the cap (14) at least partially laterally surrounds the first portion (B5). According to the invention, a vertical extension of the peripheral skirt (C5) is smaller than a vertical extension of the first portion (B5) of the peripheral body wall (11) so as to form a gap (J8') between the step (B2) and the peripheral skirt (C5) when the cap (14) is snapped onto the canister body (12).

Description

technical field [0001] The present invention relates to a steel material for vacuum carburizing, and more specifically, to a steel material for obtaining a carburized part having excellent surface fatigue properties and bending fatigue properties after vacuum carburizing, and to a manufacturing method and a steel material using the same carburized parts, and methods of making such parts. The steel material of the present invention is useful as raw materials such as gears and shafts used in automobiles, construction machinery, and various other industrial machinery. Hereinafter, the case where it is applied to automobile gears will be described as an example, but it is not limited thereto. mean. Background technique [0002] Looking at the environment of automobiles, construction machinery, and various other industrial machinery, there are social demands for energy saving and performance improvement. In recent years, efforts to reduce the weight of automobile bodies and incr...

AI Technical Summary

Problems solved by technology

The purpose of the description is that surface hardening such as gas carburizing, vacuum carburizing, carbonitriding, high concentration carburizing (hypereutectoid carburizing) and shot peening can also be performed on this case hardened steel. In the technology of Patent Document 2, it is considered that the improvement of the softening property of the surface layer is insufficient.

Therefore, according to the technology of Patent Document 2, surface fatigue strength and bending fatigue strength that can sufficiently cope with the miniaturization of components and high stress load required recently cannot be obtained.
