ABSTRACT: A container-dispenser for cosmetics in solid stick form such as lip salves, the container being of the kind comprising a tubular body, an internally threaded follower slideably and nonrotatably fitted within the body, and a knob actuated screw-threaded spindle engaging the follower to ef fect sliding of the follower. The follower is formed as a double ended cup for assembly with the spindle either way round, the assembly being inserted into the container body so that a shoulder on the knob snaps past a retaining rib on the body. The follower is provided with a continuous ring of grooves on its periphery at least one of which tends to be aligned with a longitudinal rib in the body on assembly and a thin annular flange, pierced on assembly by the rib on the body, acts as a 401/75 sliding seal between the follower and the body.

/f i v0 i I i /9 /f l l PATENTED JUH29 l9?! INVENTORS I X/dQ/XK? MICHAEL BARNEY and JACK RAYMOND GREEN THEIR ATTORNEY CONTAINER-DISPENSER FOR COSMETICS This invention relates to container-dispensers for cosmetics in solid stick form such as lip salves and concerns containerdispensers of. the kind comprising a tubular body having an opening at each end, an internally threaded follower slideably and nonrotatably fitted within the body, and a knob-actuated, screw-threaded spindle engaging the follower to effect sliding of the follower.

The usual method of providing for the follower which carries the solid stick to be slideable and nonrotatable in the tubular body is to provide one of them with a longitudinal rib and the other with a complementary groove. Difficulty arises during assembly because of the need to align the rib and groove.

The follower is conventionally of cuplike form to carrythe solid stick of cosmetic, which is fed into the assembled container in melted liquid form to solidify in situ, and it is therefore also possible to assemble the follower wrong way round on the screw-threaded spindle.

The object of the invention is to provide a containerdispenser of the kind specified in which the above-mentioned disadvantages are avoided.

According to the invention there is provided a containerdispenser comprising a tubular body having an opening at both ends, an internally threaded follower slideably fitted within the body, the outer periphery of the follower having a continuous ring of alternate adjacent ribs and grooves at least one of the grooves aligning with a complementary rib on the body to prevent rotation of the follower within the body, and a knob-actuated screw-threaded spindle engaging the follower to effect longitudinal sliding of the follower within the body. Because of the number of grooves on the follower, one of the grooves tends to be aligned with a complementary rib of the container body, when the two are brought together for as sembly, whatever their relative rotational positions.

The grooves and ribs are preferably of Vee-shape in cross section so that the maximum number of grooves can be provided for possible engagement with the complementary longitudinal rib without unduly reducing the width of the rib where it joins the tubular body. I

ln a further feature of the invention, the follower is formed with a relatively thin external integral annular flange which acts as a sliding seal with the inner wall of the container body, which flange is thin enough to be pierced by the rib on the container body entering one of the grooves of the follower when the two are assembled together.

Further according to the invention the follower is in the form of a double-ended cup, both ends being open and an inner transverse central partition wall being provided, so that the follower can be assembled to the screw-threaded spindle either way round. With this reversible double-ended follower the external annular flange is preferably located centrally of the length of the follower.

Referring to the drawings, the container body is tubular and open at both ends, the mouth end being closable by the slide-on cap 11, the body preferably being moulded from polystyrene and the cap from polypropylene. The internal surface of the body 10 is generally cylindrical, and is formed with a longitudinal rib 12 the ends of which are spaced from the ends of the body 10. At the opposite end to the mouth end the body 10 is formed with an internal annular retaining rib l3, seem most clearly in FIG. 4.

The spindle and follower assembly comprises an externally threaded spindle 14 extending axially within the body 10 and having an integral rotatable actuating knob 15 which lies partly outside the body 10 for rotating the spindle 14, the periphery of the knob being serrated at 16. The knob 15 has an external annular shoulder adapted to snap past theinternal annular retaining rib 13 of the body 10. The spindle l4 and integral knob 15 preferably are moulded from polypropylene.

The follower 18 is moulded from softer material such as low density polyethylene and is open at both ends to be in the form of a double-ended cup having an axially central threaded bore In a still further feature of the invention the knob which carries the screw-threaded spindle is provided with an external annular shoulder adapted to snap past an internal annular retaining rib at one end of the tubular body, so that the assembly of the follower with the spindle and actuating knob can be inserted as a unit from said one end of the tubular body, and without regard to their relative rotational positions.

An embodiment of the invention will now be described with reference to the accompanying drawings, in which:

FIG. 1 is a sectional side elevation to an enlarged scale of a container-dispenser constructed according to the invention.

FIG. 2 is a plan view of the container-dispenser shown in FIG. 1, to a further enlarged scale and with the cap removed.

FIG. 3 is a side elevation of the follower.

FIG. 4 is a fragmentary sectional view to a further enlarged scale, showing a detail of construction of the body and the actuating knob.

to receive the spindle 14,.the cuplike recesses 19 at each end being separated from one another by an inner central transverse partition wall 20. The inner walls of the cuplike recesses 19 have annular grooves 21 for a cosmetic stick to key into.

The follower 18 has its outer periphery formed with a continuous ring of alternate adjacent ribs 22 and grooves 23 (H08. 2 and 3), preferably of Vee-shape as is the complementary rib 12 in the body 10.

The follower 18 is also provided with a relatively thin external integral flange 24, which in this embodiment involving a double-ended reversible follower is located centrally of the length of the follower 18. The flange 24 is thin enough to be pierced by the rib-l2 on the container body entering one of the grooves 23 of the follower.

The container body 10 is inverted and stands mouth-end down in a mould to be filled with melted cosmetic such as lip salve.

The follower 18 is screwed onto'the spindle 18 of the knobspindle unit, and since the follower 18 is reversible it does not matter which end of the follower leads as it is screwed on the spindle. Without any need for rotational orientation the follower and spindle assembly is pushed down into the upwardly presented open end of the body 10. The soft follower l8 readily passes the annular rib 13 at this end of the body 10, and the shoulder 17 of the knob 15 snaps past the rib 13 so that the knob and spindle unit is rotatably retained mounted in the body 10.

The follower 18 is forced into the melted cosmetic in the body 10, the cosmetic entering one of the cuplike recesses 19 of the follower, and being keyed therein, when it solidifies, by the annular grooves 21. As the follower 18 enters the body 10, one or other of the longitudinal grooves 23 in its periphery is more or less aligned with the longitudinal rib 12 on the inner wall of the body 10, without any need for more than the minimum of rotational orientation, and as the respective groove 23 slides along the rib 12 the latter pierces the thin flange 24 on the follower, but only where said flange 24 is opposite the rib 12. The remainder of the flange 24 is thus unbroken, and acts as a sliding seal, a very important function if the cosmetic material contains a volatile component.

It is advantageous to form a vent hole, indicated at 25 in FIG. 2, in the transverse partition wall 20 of the follower 18, both for escape of any air trapped before the follower during its insertion into the melted cosmetic material and as an overflow route for any excess material.

It will be seen that the invention provides a containerdispenser for cosmetics in solid-stick form in which many disadvantages are overcome, especially as regards ease of assembly and with the possibility of assembly errors practically eliminated. The feature of the follower being provided with a ring of adjacent ribs and grooves can be employed with a cuplike follower which is not double-ended and reversible, as also can the feature of providing a thin external annual sliding seal flange on the grooved and ribbed follower, and it is obvious that the inner wall of the body can have more than one longitudinal rib, for example two opposed ribs'can be employed.
