DISPENSING CONTAINER Filed May 16, 1960 INVENTOR5. Pdu/ A Mara/20777 BY fianmVwef/a T @NEV.

United States Patent 3,095,598 DISPENSING CONTAINER Carmen J. Gonnella, Succasunna, N1, and Paul A. Marchant, Kansas City, Mo., assignors, by direct and mesne assignments, to The Mennen Company, a corporation of New Jersey and Consolidated Thermoplastics Company, a corporation of Delaware Filed May 16, 1960, Ser. No. 29,528 5 Claims. (Cl. 15-.571)

This invention relates to containers employing a roller element to dispense the liquid contents thereof and refers penser; the patent to De Brock, 2,700,784, issued February 1, 1955, for Ball-Type Liquid Applicator and Closure for Same; and the patent to Testa, 1,977,414, issued October 16, 1934, for Perfume Dispenser.

When applying liquids (such as deodorants) of various sorts to areas of the human skin or the like, it has been discovered desirable in various-applications to employ roller elements which vary from circular in cross section to elliptical in side view in one dimension or in cross section in one dimension. As a substantial elliptical shape is approached, greater area of contact is provided, which is desirable for applying deodorants, perfumes or the like. The problem of adequately sealing an elliptical roller element in its seat (to prevent liquid flow from the container when the top thereof is on) 'is very difficult, particularly when the seal is desired to be made in a plastic seat for the roller element. Such plastic seats are conventionally relatively deformable in themselves and, also, not commercially fabricable or formable beyond a certain level of accuracy. The more elongate the ellipse and the more flexible the material of the plastic seat, the less likelihood of obtaining a uniform satisfactory seal. Various additive sealing constructions have been built into plastic seats for elliptical rollers, but none have provided effective seals under all necessary conditions. Additionally, it is desired to minimize the expense of the roll-on fitting as the container and roll-on. element are regarded as disposable items.

Therefore, an object of the instant invention is to pro-' vide means for scaling in adequate fashion an elliptical roller element for dispensing liquids from containers.

Another object of the invention is to provide such means for sealing which are simple in construction, relatively easy to manufacture and relatively inexpensive.

Another object of the invention is to provide means for sealing elliptical rollers which involve the combination therewith of a resilient element, the latter preferably substantially cylindrical in form.

Another object of the invention is to provide an insert construction including an elliptical roller element, which insert is adapted to seal the container against flow therefrom when the container top is applied and dispense the liquid from the container when the top is removed.

Another object of the invention is to provide an elliptical roller element and seal therefor for roller dispenser containers which will meet all of the seal tests of conventional spherical roller element roll-on containers as to temperature, pressure and inverted position sealing.

3,095,598 Patented July 2, 1963 Another object of the invention is to provide a roll-on container construction which combines the applicator features of an elliptical roller with the sealing features of a spherical roller.

Other and further objects of the invention will appear in the course of the following description.

In the drawings, which form a part of the instant invention and are to be read in conjunction therewith, embodi merits of the invention are shown and, in the various views, like numerals are employed to indicate like .parts.

FIG. 1 is a side elevation, partly cut away and in section, of an inverted elliptical roll-on container embodying the invention with the top thereof in place.

FiG. 2 is a fragmentary sectional view taken along the line 22 of FIG. 1 in the direction of the arrows.

FIG. 3 is a fragmentary sectional view similar to that of FIG. 2 but with the container top removed and the roller element in dispensing position.

FiG. 4 is a top plan view of the roller assembly casing with the elliptical roller element removed therefrom.

FIG. 5 is a sectional view taken along the line 55 of FIG. 4 in the direction of the arrows.

FIG. 6 is a sectional view taken along the line 6-6 of H6. 4 in the direction of the arrows.

FIGS. 1 and 2 show the container in normal storage condition with FIGS. 1 and 2, however, inverted from the normal storage position. The invention comprises, in combination, a container body, a preferably elliptical roller element and a fitment including: a first socket for the elliptical roller element, a resilient element, the latter preferably of cylindrical form with an opening therethrough, a second socket for the resilient element and two openings communicating out of the second socketone opening into the first socket and one opening into the body of the container. This fitment may be applied to and mounted on the container body in a number of ways. The method of applying the roller element and fitment to the container body illustrated is only typical and should not be construed as limiting.

Referring first to FIG. 1, therein is shown a container construction having three basic parts. The first part is the container body portion generally designated at 10, the second the container top portion generally designated at 11, and the third the roller fitment generally designated at '12. These pants will be described in the order named. All container parts except the roller which is made of glass or like rigid material, may preferably be formed of polyethylene or like resilient plastic material.

The container body 18 has a circumferential side wall 10a, an upper unbroken end wall 10b continuously connected to or formed continuous with side wall 10a and lower end wall which has an opening 10d preferably centrally thereof, to be described. A continuous circumferential groove 102 is formed in side wall 10a of the container body 10 just above lower end wall 100. Wall 10a is preferably recessed inwardly to form groove 10c and an extension 10f defines the lower wall of the groove. The Wall 10c is preferably recessed at 10g the width of the roller insert skirt to be described.

Central opening 10d is preferably, though not necessarily, circular in form. Opening 10d is defined by circumferential flange or ring 1011, fixed to or formed integral with wall 19c and having groove 101' formed centrally of the inner face thereof. Alternatively (and not shown) an inwardly-extending ridge or raised portion may be formed on' the flange 16h if the engagement between the roller element and opening" 10d is desired to be reversed. The thickness of flange 1011 is preferably greater than the thickness of wall whereby to provide greater rigidity for the engagement to be described.

The container top 11 is congruent in transverse section to the transverse section of container body and must be of sufficient depth to receive the roller assembly when the top is engaged with the container body. Means for engaging container body 10 are provided and comprise, in the instance shown, bead 11a formed circumferentially inwardly of the peripheral wall 11d of top 11. Bead 11a engages groove ltle to form a circumferential sealing fit of the top of the container. Fixed to the inner side of lower end wall 11b of top 11 are flange extensions 1'10 adapted to contact the roller element when the top is in positive engagement with the container body and force the roller element or other means in contact therewith into sealing roller relationship with its seat. It should be noted that the groove-head engagement of groove 10c and bead 11a may be reversed (if desired) with the bead on the container and the groove in the top. However, it is preferred that the wall of the container be in line with the wall of the top when in engagement and this is most easily achieved in the construction shown.

The roller assembly shown employs a roller elliptical along one axis in combination with a resilient perforated element wherein the elliptical roller provides the desired large area dispensing, with the resilient element providing a proper seal when the top is on to avoid underside passage of liquid from the container body proper.

Referring particularly to the roller assembly, elliptical roller 13 (elliptical in one dimension and round in the dimension normal thereto) is received in socket 12a, the latter provided with a plurality of extensions 12b uniformly and circumferentially positioned to opening 120. Cylindrical resilient element 14 of rubber, resilient plastic, or the like, having axial opening 14a therethrough is received in a recessed well or socket defined by upwardly-extending flange 12d, the latter having inwardlyextending upper edges 12c which taper interiorly to define upper opening 12]. Depending upon the engagement desired, either a ridge 12g (shown) or groove (not shown) is provided to engage an opposite means on flange 10h. Socket 12a surrounds, engages and overlies a sufficient portion of roller 13 so as to maintain it 'within the socket in use. Wells 1211 at the extremities of the seat receive the elongate roller ends for rotational motion. Skirt 121" is preferably circumferentially fixed to the lowermost periphery of socket 12a and is so formed and of such length as to be received in recess or groove 10g of the container body 10.

Reference may be made to FIG. 2 to ascertain that the engagement of the roller fitment with the top of the container is solely and primarily, as far as rigid fixing and positioning goes, effected by the central engagement of flange 12d with flange 10h. Thus this connection must be of suflicient rigidity and tenacity to retain position of the roller assembly on the container proper in normal operation of the container in dispensing liquid therefrom. Skirt 12: serves to keep foreign matter out of the container body 10 and out of the space between the roller insert and the container and, additionally, improve the appearance thereof. Additionally, some protection is provided to the central engagement by the skirt (depending upon the strength and rigidity thereof) against lateral forces applied. Additionally, skirt 12i in its abutment on wall 100 aids in resisting further insertion of flange 12d into the opening 10d under excessive upward pressure.

In operation of the device, the container, in inverted position as shown in FIG. 1, is filled with the liquid to be dispensed. Then the roller fitment is snapped vertically downwardly into place so that bead or ridge 12g fits into slot or groove 101' circumferentially. Skirt 12i aids in such positioning by fitting into groove or recess 10g. When top 11 is fitted over the roller assembly and container so that bead 11a fits into groove 10c, means 11c abuts the surface of roller 13, forcing cylindrical grommet 14 into an expanded sealing engagement with flange 12d, the roller 13 on top thereof sealing the outward extension of the opening or passage 14a as shown in FIG- URE 2 and thus preventing any influx of liquid into the space surrounding the roller and the socket 120. Removal of the top permits the movement of roller 13 and grommet 14 into the position of FIG. 3 and permits flow of liquid into socket 12a to be transferred onto the roller by rotation thereof. The diameter of opening 14a may be varied as desired according to the viscosity of the liquid dispensed to permit flow of ample liquid to roller 13. Extensions or projections 12b, which are flexible, serve to elevate the roller 13 on removal of the top to free opening 14a, yet are forceable outwardly to enable the roller to seal the grommet 14 opening 14a on top application.

From the foregoing it will be seen that this invention is one Well adapted to attain all of the ends and objects hereinabove set forth together with other advantages which are obvious and which are inherent to the structuire.

It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.
