Device for containing, dispensing, and applying to an application surface a content in liquid, gel, cream, or paste form, in the closed/associated state prior to use, able to be placed in the open/separated state for use by means of an opening/separation operation, comprising, with an axis, a shaped semi-rigid wall, a closing wall, and an applicator having an attachment portion and an application portion that are extensions of one another, such that: ▪ the shaped semi-rigid wall comprises a flat peripheral edge and a recess located on one side of the plane of the edge and surrounded by it, having, as extensions of one another and in communication, a content receiving portion that is deformable by means of external pressure, an attachment part with inner projection and a protection portion respectively engaging with the attachment portion and the application portion of the applicator, ▪ the closing wall covers the shaped semi-rigid wall, is rigidly secured to the edge, and seals the recess to provide a content vessel, an attachment cavity for the attachment portion of the applicator, and a protective enclosure for the application portion of the applicator which is adapted, during the opening/separation operation, to separate from said application portion in order to expose it, ▪ a breakable means of the shaped semi-rigid wall and of the closing wall is located transversely between the attachment part and the protection portion, and is adapted to break for the opening/separation operation, ▪ a content-transfer passage extends along the axis between, and in communication with, the content vessel and the application portion of the applicator, so that, in order to use the device in the open/separated state, content is transferred from the content vessel to the application portion of the applicator when external pressure is exerted on the receiving portion of the shaped semi-rigid wall, characterized in that the content-transfer passage is made with a structure having radial spacing that ensures there is no peripheral sealing between the outer peripheral surface of the attachment portion of the applicator and the facing inner peripheral surface of the attachment part of the shaped semi-rigid wall, the structure with radial spacing extending in a communicating and continuous manner along the axis, between the content vessel on the one side, and the breakable means and application portion of the applicator on the other, and in that the content to be applied from the application portion of the applicator is supplied from its outer peripheral shell, while the content is capable of passing through the transfer passage and of being applied as though with a brush. ▪ the shaped semi-rigid wall comprises a flat peripheral edge and a recess located on one side of the plane of the edge and surrounded by it, having, as extensions of one another and in communication, a content receiving portion that is deformable by means of external pressure, an attachment part with inner projection and a protection portion respectively engaging with the attachment portion and the application portion of the applicator, ▪ the closing wall covers the shaped semi-rigid wall, is rigidly secured to the edge, and seals the recess to provide a content vessel, an attachment cavity for the attachment portion of the applicator, and a protective enclosure for the application portion of the applicator which is adapted, during the opening/separation operation, to separate from said application portion in order to expose it, ▪ a breakable means of the shaped semi-rigid wall and of the closing wall is located transversely between the attachment part and the protection portion, and is adapted to break for the opening/separation operation, ▪ a content-transfer passage extends along the axis between, and in communication with, the content vessel and the application portion of the applicator, so that, in order to use the device in the open/separated state, content is transferred from the content vessel to the application portion of the applicator when external pressure is exerted on the receiving portion of the shaped semi-rigid wall,
