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).

Embodiment

[0094] Hereinafter, the present invention will be described more specifically with reference to examples. The present invention is not limited by the following examples, and within the range that can meet the above-mentioned and hereinafter-described purposes, of course, it can also be appropriately modified and implemented, and these are included in the technical scope of the present invention.

[0095] Steels having the chemical composition shown in Table 1 below were melted, held at 1250° C. for 30 minutes to 300 minutes, and then billet-rolled. The balance of the chemical composition shown in Table 1 is iron and unavoidable impurities. Thereafter, as shown in Tables 2 and 3, the pre-rolling heating temperature is 920° C. to 1100° C., and the heating retention time is 0.3 to 6 hours to perform hot rolling to obtain The hot-rolled material, that is, bar steel. Note that Steel No. 1 shown in Table 1 is a steel equivalent to the conventional steel SCr420H.
