    摘要

    NOVELTY - Preparation of heterophasic propylene copolymers involves: a)polymerizing propylene, optionally together with at least one alpha-olefin comonomer, in the presence of hydrogen and catalyst to produce a crystalline polymer fraction; and b)copolymerizing ethylene with propylene and/or 1-butene, and optionally at least one 5-12C alpha-olefin comonomer under fast fluidization or transport conditions.

    USE - For gas-phase polymerization of propylene, particularly heterophasic propylene copolymers. Also useful in the manufacture of parts, components and materials in automotive industry, such as automotive interior trims and bumpers and items of industrial consumer market, including the medical, furniture, appliance industries, building/construction and recreation/sports industries.

    ADVANTAGE - The obtained heterophasic propylene copolymers show Izod impact values at 23degreesC higher than 44 kJ/m2, in combination with values of flexural modulus higher than 1115 MPa. The propylene copolymers are particularly suitable for producing items endowed with a good balance of stiffness and impact resistance; show high values of flowability.

    DETAILED DESCRIPTION - Preparation of heterophasic propylene copolymers by polymerizing propylene in the presence of a polymerization catalyst and hydrogen as a molecular weight regulator, the process comprising the following steps: a) polymerizing propylene in a gas- or liquid-phase, optionally together with at least one alpha-olefin comonomer, to prepare a crystalline polymer fraction; b) copolymerizing ethylene with propylene and/or 1-butene, and optionally at least one 5-12C alpha-olefin comonomer, in a gas-phase reactor having interconnected polymerization zones, the growing polymer particles flow upward through a first polymerization zone (riser) under fast fluidization or transport conditions, leave the riser and enter a second polymerization zone (down-comer) through which they flow downward under the action of gravity, leave the downcomer and are reintroduced into the riser, thus establishing a circulation of polymer between the two polymerization zones.

    [0001]CROSS REFERENCE TO RELATED APPLICATIONS
    [0002]This application is entitled to the benefit of provisional patent application No. 61/763,114, filed on Feb. 11, 2013, the specification of which is incorporated herein by reference.
    [0003]BACKGROUND OF THE INVENTION
    [0004]The present invention relates to a tool for easily applying lotion to a desired body part.
    [0005]DESCRIPTION OF THE PRIOR ART
    [0006]Applying lotions to certain areas of the body can be difficult and challenging. Typically, the lotion is first delivered to the hands, which are then used to spread the lotion over other desired body parts. However, the elderly or those who are otherwise inflexible are unable to reach certain areas of the back or other remote areas without assistance. Conventional lotion applicators that purportedly overcome the aforementioned problems typically include an elongated handle having a sponge or brush at a distal end. However, because neither the handle nor the brush is adjustable, a user is often unable to effectively access certain remote areas.
    [0007]Accordingly, there is currently a need for an improved lotion applicator that overcomes the above-described problems. The present invention addresses this need by providing a lotion applicator having a telescoping shaft and an angularly adjustable handle for easily positioning an applicator head, as desired.
    [0008]SUMMARY OF THE INVENTION
    [0009]The present invention relates to a lotion applicator comprising an elongated, telescoping shaft having an applicator head attached to an end thereof. Pivotally connected to an opposing end of the shaft is an angularly adjustable handle. Accordingly, a user places lotion on the applicator head and reciprocates it on a desired portion of the body. If necessary to reach a certain area, the shaft can be extended or retracted, and/or the handle can be adjusted to a desired angle.
    [0010]It is therefore an object of the present invention to provide a lotion applicator that allows a user to more easily access all areas of the body.
    [0011]It is another object of the present invention to provide a lotion applicator having an adjustable handle for more easily reaching otherwise inaccessible areas.
    [0012]Other objects, features and advantages of the present invention are readily apparent from the following detailed description of the preferred embodiment, the attached drawings and the appended claims.
    [0013]BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a top, plan view of the lotion applicator according to the present invention. FIG. 2 is a side view of the applicator. FIG. 3 an isolated, top view of the applicator head. FIG. 4 an isolated, side view of the applicator head. FIG. 5 is an isolated view of the shaft. FIG. 6 is an isolated view of the shaft in an extended position. FIG. 7 is an isolated view of the shaft with the handle obliquely positioned relative thereto. FIG. 8 is an isolated view of the spring-biased latch. FIG. 9 is an isolated view of the ball-detent mechanism.
    [0014]DESCRIPTION OF THE PREFERRED EMBODIMENT
    [0015]The present invention relates to a lotion applicator comprising an elongated shaft 1 formed of at least two length-adjustable sections. An inner section 2 having a plurality of longitudinal openings 3 is telescopically received within an outer section 10 having a spring-biased latch 4 at an end thereof. The latch includes a pivotal lever 30 with a pin 5 at a first end and a spring-biased button 31 at an opposing end. Depressing the button 31 lifts the pin 5 from a receiving aperture, allowing a user to adjust the length of the shaft, as desired.
    [0016]Attached to the distal end of the outer section is an ovate applicator head 6 formed of a rigid inner shell 11 encapsulated by an outer layer 12 of silicone rubber. The head includes a relatively planar lower surface 15 and an arcuate upper surface 16 , either of which can be used to apply lotion according to the contour of the target area. A handle 7 is pivotally connected to the distal end of the inner section with a spring-biased, ball-detent mechanism 8 that allows the handle to be locked in either of a 0, 30, 60 or 90-degree angle relative to the shaft. An accordion-style, rubber hinge-guard 9 covers the ball-detent mechanism.
    [0017]Accordingly, a user places lotion on either surface of the applicator head and reciprocates it on a desired portion of the body. If necessary to reach a certain area, the shaft can be extended or retracted, and the handle can be adjusted to a desired angle.
    [0018]The above-described device is not limited to the exact details of construction and enumeration of parts provided herein. Furthermore, the size, shape and materials of construction of the various components can be varied.
    [0019]Although there has been shown and described the preferred embodiment of the present invention, it will be readily apparent to those skilled in the art that modifications may be made thereto which do not exceed the scope of the appended claims. Therefore, the scope of the invention is only to be limited by the following claims.
