Embodiment Construction

[0041] figure 1 An exemplary schematic diagram of a snap-fit ​​connection of a tank of the prior art is shown. The body wall 11 of the tank body 12 includes a first portion B5 located adjacent to the upper opening of the tank body and a second portion B6 below the first portion B5. The first part B5 comprises a protrusion B7 and a recess B1 and a step B2 between the first part B5 and the second part B6 , wherein the step B2 extends perpendicular to the vertical extent of the tank body wall 11 . The uppermost part B4 of the tank main body wall 11 is also figure 1 described in.

[0042] figure 1 Also disclosed is an exemplary illustration of a cover 14 comprising a disc-shaped top C6 and a peripheral skirt C5. The skirt C5 comprises a protrusion C1 and a recess C7 and the protrusions and recesses of the skirt C5 respectively interact with the first part B5 to provide a snap connection between the lid 14 and the can body 12 .

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 canister for containing an active agent, such as a desiccant, oxygen scavenger or fragrance, and for allowing the active agent to interact with the canister's environment, such as absorbing moisture, oxygen or odors, when the canister is closed, Or release moisture or fragrance. The invention is of course also applicable to other active agents intended to deliberately modify the surrounding atmosphere inside the package into which the can of the invention is introduced. [0002] The invention also relates to a method of manufacturing such a tank. Background technique [0003] Cans according to the above-mentioned technical field are generally common and well known to be placed inside the packaging of goods for increasing the shelf life of goods or substances sensitive to moisture, oxygen or other gases and contained in the packaging. Active agents such as desiccants or oxygen scavengers are well known in the art and...
