  • Patent number: 12029304
    Abstract: A paper lipstick tube with threads, including a lipstick tube body which includes an A lipstick tubing, a B lipstick tubing, a C lipstick tubing, a pin, a D lipstick tubing, an F lipstick tubing, an M lipstick tubing, a K lipstick tubing, a cover tube H, a circular gasket and cream. The B lipstick tubing is rotatably installed inside the F lipstick tubing. The lipstick tube body is a container with a push-pull function made of only paper and a small amount of natural bamboo or wood materials. Through mutual rotation of the F lipstick tubing and the B lipstick tubing, upward and downward shearing forces are applied to the pin spirally through the threaded groove in the B lipstick tubing. At the same time, the pin is also in up-and-down guide openings of the D lipstick tubing, so that the C lipstick tubing can only move up and down.

    Abstract: A stick-shaped material extruding container for performing forward and backward movements of a stick-shaped material without trouble and prevent detachment of the stick-shaped material by an impact. A movable body having a piston-like extruding portion, closely attached within a filling member, is arranged within a container. The stick-shaped material is loaded in the filling member so as to be closely attached to the filling member and the piston-like extruding portion. When the stick-shaped material is pushed by a forward movement of the piston-like extruding portion to appear from an opening of the container, a sucking action is generated due to decompression between the piston-like extruding portion and the stick-shaped material by a backward movement of the piston-like extruding portion to retract the stick-shaped material, and the decompression prevents falling off of the stick-shaped material from the container.

A cam member is rotatably engaged with an adapter member in a mating relationship. An elevator member with a cosmetic retaining portion and an elevator rod move axially in response to a rotation of the cam member in relation to the adapter member. A proximal end of the elevator rod can be received through an elevator aperture in the adapter member to enable a sliding of lugs on the elevator rod along a helical thread of the cam member. Frictional drag between the cam member and the adapter member can be produced by one or more drag protuberances therebetween. Where the drag protuberances project from the adapter member, a thin wall portion therein can enable a resilient deflection of the drag protuberances.

The container includes a rod which extends along the central axis, the rod having an integral lower wall which has an annular skirt which engages an annular projection on the bottom of the outer body. The inner body has a integral partition wall extending radially (transverse to said axis) and having elastic tabs which slide on a toothed configuration fixed with respect to the outer body.

  • Patent number: 4984919
    Abstract: A lipstick-type cosmetic case with inner and outer coaxial sleeves with respective axial and helical cam tracks receiving cam followers for reciprocating a cosmetic pomade support within the sleeves. The axial cam tracks in the inner sleeve have inner restricted sections with upper tapered end pockets for receiving the cam followers and restricting inward axial movement therefrom. The helical cam tracks in the outer sleeve have upwardly facing continuous helical cam edges on one edge thereof and, on the opposite edge thereof, two inwardly facing stepped helical edge sections and an intermediate inwardly facing locking edge section for locking the followers against outward axial movement from the pockets.

  • Patent number: 4983059
    Abstract: An improved cosmetic preparation dispenser is provided which comprises a hollow body forming an elongated chamber for containing the preparation therein in a shape corresponding to the chamber. A holder member is slidably mounted inside the hollow body for holding one end of the preparation while being moved along a line of travel either in a first or second direction within the hollow body to respectively extend and retract the preparation through an opening at one end of the hollow body. Means are also provided spaced along the line of travel for lockingly detaining the holder member at at least two stations spaced along the line of travel, the lockingly detaining means being releasable under operator control to permit the holder member to be moved from station to station, whereby the preparation can be lockingly retained at predetermined stations along the line of travel.

  • Patent number: 4976561
    Abstract: A writing tool in which a core casing (3) or (3a) is inserted in an outer sleeve (2), and an end (6) of core casing (3) or (3a) can be projected out of the end of outer sleeve (2) by operating end (4a). End 6 of core casing (3) or (3a) can be withdrawn by reverse operation of the operating end (4a). A revolution-to-linear movement conversion arrangement for converting a revolutional movement of an operating end (4a) to a axial movement between a core casing (3) or (3a) and an outer sleeve (2) is provided. A retracting spring (5) between the outer sleeve (2) and the core casing (3) or (3a) and the operating end (4a) projecting out of a rear end of the outer sleeve (2) can be forcibly operated against the force of a retracting spring (5).

  • Patent number: 4865480
    Abstract: An applicator for dispensing metered amounts of medicaments in stick formulations is comprised of a hollow tube and a piston mounted to slidingly move within the tube. A finger operable base is rotatably mounted at one end of the tube and is mechanically linked by a screw member to the piston to urge the piston towards the other end of the tube. A depressible thumb piece is associated with the rotatable base. An extension or post is associated with the thumb piece to extend inward of the tube and to register with a race formed inside the tube. The race has a series of detents with which the extension may register upon rotation of the base. Registration between the extension and the detents signals certain increments of rotation or prevents further rotation of the base. The thumb piece is depressed inward to bring the extension out of registration with the detents.

  • Patent number: 4792251
    Abstract: A lipstick container having an attractive noncircular form includes a unique operating mechanism for reciprocating a cup member adapted to hold a mass of lipstick. The operating mechanism includes a friction ring which is fitted on the outer body member whereby a constant swivel torque is required to opereate the mechanism through the length of its stroke. The friction ring creates a smoothly operating, luxurious feeling mechanism, limits relative axial movement or "shuck" between the inner and outer body members, and eliminates the need for a bottom pair of lock extension slots.

  • Patent number: 4603989
    Abstract: The invention contemplates a cosmetic-container of the propel-repel variety wherein all parts are assembled and retained by interference fit and wherein metal-to-plastic interfaces characterize essentially all sliding engagements. The arrangement is such as to provide a luxury "feel" through controlled drag torque (resistance) to relative rotation of the parts. And provision is made to positively retain any retracted position of the pomade carrier, whatever the remaining useful extent of involved pomade.

  • Patent number: 4357117
    Abstract: A nib holder for a fine molded nib in a writing instrument is disclosed. The nib holder has an internal passageway into which the nib may be inserted and held by an abrasive ring or by projections, the nib being held without substantial deformation thereof. The nib holder includes a screw threaded portion which cooperates with mating screw threads on the casing of the writing implement. The nib holder may be screwed into the casing until the end of the nib contacts a fixed ink conducting core. Therefore, as the nib holder is screwed into the casing, the nib is forced out of the passage in the holder for compensating for wear of the nib. A cooperating prong and detent on the casing and nib holder control the rotation of the nib holder with respect to the casing.
