ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a lipstick housing, and more particularly to a lipstick housing having an increased strength.
2. Description of the Prior Art
Typical lipsticks comprise a barrel, a tube rotatably received in the barrel, and a seat slidably received in the tube for receiving the lipstick material. The seat is to be moved along the tube for moving the lipstick material inward and outward of the barrel. The barrel is required to be held in place by one hand of the user when the other hand of the user rotates the tube. However, the barrel is weak and will be easily deformed inadvertently by the user.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional lipstick housings.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a lipstick housing having an increased strength for preventing the lipstick housing from being deformed by the user.
In accordance with one aspect of the invention, there is provided a lipstick housing comprising a barrel, a ferrule includes a tube extended therefrom and rotatably engaged in the barrel, the tube including at least one slot formed therein, a seat slidably received in the tube for holding a lipstick material, and means for guiding the seat to move along the tube when the tube is rotated relative to the barrel. The barrel includes a free end having a peripheral flange extended and curved radially inward therefrom and extended downward for forming a reinforcing end portion and for preventing the barrel from being deformed by a user when the user holds the barrel.
The guiding means includes a cylindrical member secured in the barrel and having a helical groove form ed therein, the seat includes at least one projection extended therefrom and slidably received in the slot of the tube and slidably received in the helical groove of the cylindrical member for guiding the seat to move along the tube when the tube is rotated relative to the barrel.
The tube includes a radially inner diameter no less than that of the peripheral flange of the barrel for preventing the lipstick material from engaging with the peripheral flange of the barrel when the lipstick material is moved outward of the tube by rotating the tube relative to the barrel with the ferrule.
A cover is further provided and includes at least one rib extended downward therefrom for engaging with the peripheral flange of the barrel and for allowing the cover to be secured to the barrel with a force-fitted engagement.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
