A hand-held device, in particular a writing instrument, comprising a body, a single carriage carrying a first head and a second head, or a first carriage and a second carriage carrying respectively the first head and the second head, and a blocking device including a cavity and a ball, the ball) blocking the single carriage or the first carriage when the first end is below the second end, such that the first head is blocked and projecting while the second head is retracted, and the ball blocking the single carriage or the second carriage when the first end is above the second end, such that the second head is blocked and projecting while the second first head is retracted.

A cosmetic application device may include a housing having an opening on a top surface, an inner tube disposed within the housing, and a wheel actuator disposed on a side surface of the housing and rotatably coupled to the inner tube. The inner tube may be configured for holding a cosmetic product stick. Rotation of the wheel actuator may cause the cosmetic product stick to move axially through the housing and out of the opening.

A manual device extends in an axial direction and includes a housing having a first housing portion and a second housing portion. First and second heads are each axially movable between a use position and a stowed position. The first head is in the stowed position when the second head is in the use position, whereas the second head is in the stowed position when the first head is in the use position. The first head and the second head both are carried by a single carriage movable in the axial direction and arranged inside a barrel. A groove forming a cam track is formed by a first shoulder of the first housing portion and by a second shoulder of the barrel. A lug of the carriage cooperates with the groove.

Device for packaging, dispensing and applying a solid or pasty block of cosmetic product The present application relates to a device for packaging, dispensing and applying a block of solid or pasty cosmetic product, comprising a longitudinal tubular case having an open first end, intended for dispensing the cosmetic product, and an opposite second end that is closed by a base accommodating a mechanism for driving a support for holding said cosmetic product in translation along the case, characterized in that the device has, at the open first end of the case, an external envelope with a longitudinal central axis offset radially with respect to a longitudinal central axis of an external envelope of the device at the opposite end of the case that is closed by the base.

A rod-shaped object feeding container includes a cartridge unit and a knock mechanism unit. The cartridge unit includes a movable body and a female screw member. The knock mechanism unit includes a coupling member, a knock member, a spring member, a main body tube, and a rotary member. When the knock member is pressed, the knock member converts a force with which the knock member is pressed into a rotational force and causes the coupling member and the female screw member to be rotated in one direction so as to advance the movable body and the rod-shaped object. When the rotary member is rotated relative to the main body tube in an opposite direction, the rotary member causes the coupling member and the female screw member to be rotated in the opposite direction so as to retract the movable body and the rod-shaped object.

A mechanism for a case for applying a cosmetic product having a main axis includes a sleeve arranged around a head of a guide to which the sleeve is secured. The head of the guide includes snap-fitting attachment means configured to cooperate with complementary means of the sleeve in order to axially immobilize the sleeve with respect to the guide, and rotational blocking means intended to cooperate with the complementary means of the sleeve to rotationally block the sleeve with respect to the guide.

A feeding pencil includes a body, a leading tube, a middle tube, a pipe member including drawing materials, a movable body, a holding member, and a sliding part. The drawing material moves forward in the leading tube when the pipe member engages with the leading tube in a rotating direction by moving the sliding part forward by a predetermined amount, when the leading tube and the body are rotated relatively in one direction while the pipe member is engaged with the leading tube in the rotating direction. The sliding part includes a stick-like part with a spring, and the stick-like part is inserted into an opening of a housing, and the sliding part is urged rearward by the spring when one end of the spring abuts the housing, and the other end of the spring abuts a face protruding radially outwardly from the stick-like part.

A rod-shaped cosmetic material feeding container having a movable body housed in a container main body in which the movable body advances by an operation of an operating portion. A rod-shaped cosmetic material is fed by the advance of the movable body to project from an opening of a leading tube. The leading tube has the tip end and a main body, the tip end being made of a soft material, the main body being installed consecutively to the tip end and extending in an axial direction. Further, the main body of the leading tube is made of a hard material and has an elongated tube hole (e.g., having a drop or rhombic shape in cross-section) formed inside. A top end surface on the tip end has a tapered surface tapered to peak at an outside surface of the tip end when viewed from a tip side.

A writing instrument according to an embodiment of the invention including, a chuck that chucks a writing lead, wherein the chuck includes a first chuck pawl which comes into point contact or line contact with the writing lead to press the writing lead so as to apply first contact stress to the writing lead; and a second chuck pawl which presses the writing lead so as to apply, to the writing lead, second contact stress that is lower than the first contact stress, and the first contact stress is configured such that, when a prescribed impact is applied to the writing lead, a contact portion of the writing lead subjected to the first contact stress fractures and absorbs the prescribed impact.

A hand held device presenting a first head and a second head that are movable axially between a position for use and a retracted position, and a single side button configured to bring the first head and the second head, independently of each other, from the retracted position to the position for use and vice versa, the side button cooperating with a first ratchet mechanism in order to cause the first head to pass from the retracted position to the position for use and vice versa, and with a second ratchet mechanism in order to cause the second head to pass from the retracted position to the position for use and vice versa.
