Definitions

  • the invention relates to cosmetics container and more particularly to an environmentally friendly cosmetics container formed of food grade polyethylene terephthalate (PET).
  • PET polyethylene terephthalate
  • a cosmetics container is used for housing makeup products and implements a mechanism of ascending or descending makeup products by rotation.
  • a conventional cosmetics container mostly comprises six components, including a casing, a rotation body, a carrier, a core, a cap, and a lower exterior case.
  • the components are made of polyoxymethylene (POM) and acrylonitrile butadiene styrene (ABS) resin.
  • POM polyoxymethylene
  • ABS acrylonitrile butadiene styrene
  • Multiple components of the conventional cosmetics container are difficult to assemble with lower productivity.
  • POM is white and ABS resin is yellow, as a result, the color of the cosmetics container is limited to one.
  • it is required to add a great amount of other dyes to cover colors of both POM and ABS resin. It not only increases the manufacturing cost, but also makes it impossible of making the color of the cosmetics container to be a specific color.
  • EP 1 133 937 B1 discloses a device for storing and applying cosmetic care products.
  • Plastic components of the device are made of non-polyolefinic plastics, e. g. polyethylene terephthalate.
  • the case comprises an outer covering comprising a body or base, a removable cap and a drive mechanism intended to allow the axial displacement of a stick of product.
  • the mechanism consists of the assembly of three elements, namely a sheath, a stick cup and a casing.
  • the sheath and the cup are made of plastic material and the casing comprises a sleeve of metal lined by an inner jacket of plastic material.
  • the cup comprises two diametrically opposed lugs arranged to slide in two diametrically opposed guide slots of the sheath.
  • the upper and lower ends of the guide slots are extended in radial, opposite directions.
  • the ends of the lugs engage in helical grooves in the inner jacket, so that a rotational movement of the sheath relative to the casing is accompanied by an axial movement of the cup.
  • the body comprises a chimney which engages in the sheath and which is prevented from rotating relative to the latter. To cause the stick of product to come out, the user turns the casing relative to the body after removing the closure cap.
  • an environmentally friendly cosmetics container 10 in accordance with the invention is shown, which is formed of food grade PET and comprises a cap 11, a rotation tube 12, an ascending and descending tube 14, a support tube 16, and a lower exterior casing 18.
  • FIG. 1 shows a perspective view of the cap 11 and the lower exterior casing 18 being combined.
  • the cap 11 includes an annular groove 111 on an open bottom of an inner surface.
  • the rotation tube 12 is hollow and includes a plurality of spiral guide grooves 121 on an inner surface.
  • the ascending and descending tube 14 includes two opposite and protruded guide pins 141 on an outer surface, and a plurality of parallel longitudinal ribs 142 are formed on an inner surface and spaced apart.
  • the ascending and descending tube 14 houses a cosmetic product 20, and a bottom of the cosmetics product 20 is secured by the parallel longitudinal ribs 142.
  • the support tube 16 is hollow and includes two opposite longitudinal tunnels 161 on a surface, each of the longitudinal tunnels 161 having an upper horizontal end 1621 and a lower horizontal end 1622 oriented in a direction opposite to that of the upper horizontal end 1621.
  • the upper horizontal end is parallel to the lower horizontal end 1622.
  • the lower exterior casing 18 is a receptacle and includes an annular shoulder 181 being stepped on an outer surface.
  • a plurality of projections 182 disposed on a stair riser proximate a top end of the annular shoulder 181.
  • a protrusion 183 on a blind bottom of the lower exterior casing 18 is configured to dispose in the annular toothed member 165.
  • the rotation tube 12 is put on the support tube 16.
  • the ascending and descending tube 14 is disposed in the support tube 16 and the guide pins 141 are moveably disposed through the longitudinal tunnels 161 into the spiral guide grooves 121, so that the guide pins 141 are anchored in the upper horizontal ends 1621 or the lower horizontal ends 1622 at the end of the movement.
  • the lower exterior casing 18 houses the rotation tube12, the ascending and descending tube 14 and the support tube 16 when combined.
  • the protrusion 183 is secured to the annular toothed member 165.
  • the cap 11 is secured to the lower exterior casing 18 by resting upon the shoulder 181 and snapping the annular groove 111 onto the projections 182.
  • the support tube 16 further comprises a longitudinal cut 163 through a top edge and communicating with one of the upper horizontal ends 1621.
  • the longitudinal cut 163 has a width less than a diameter of the cylindrical guide pin 141.
  • the provision of the longitudinal cut 163 are providing the support tube 16 space for thermal expansion and facilitating the guide pins 141 to be disposed through the longitudinal tunnels 161.
  • the rotation tube 12 further comprises a curved top edge 123 to prevent an individual from being hurt when applying the cosmetics product 20.
  • the spiral guide grooves 121 are spirally formed on the inner surface of the rotation tube 12.
  • An annular trough 122 is formed at a bottom edge of the spiral guide grooves 121.
  • the support tube 16 comprises an annular ridge 164 configured to dispose in the annular troughs 122 when the rotation tube 12 is put on the support tube 16.
  • a joining strength of the rotational tube 12 and the support tube 16 increases.
  • the protrusion 183 is correspondently secured to the annular toothed member 165.
  • an individual may hold the lower exterior casing 18 with one hand and rotate the rotation tube 12 with the other hand.
  • the ascending and descending tube 14 moves upward or downward along the spiral guide grooves 121 in the inner surface of the rotational tube 12, lifting or lowering the cosmetics product 20.
