Harrison United States Patent 3,397,027 STICK-TYPE APPLICATOR CONSTRUCTION Mortimer J. Harrison, Santurce, Puerto Rico, assignor to Valve Corporation of America, Bridgeport, Conn., a corporation of Delaware Filed Jan. 25, 1966, Ser. No. 522,857 13 Claims. (Cl. 401-50) ABSTRACT OF THE DISCLOSURE An applicator construction for solidified stick-shape perfumed deodorant material of the like, comprising a tubular container having a removable screw cap provided with an interior configuration which is desired on the end of the stick material. The cap has a filling opening for engagement by a filling nozzle to deposit molten stick material in the container so that the material solidifies with an end shape conforming to said interior configuration. A closure plug is adapted to close the filling opening of the cap after the filling operation.

This invention relates to applicator-stick devices, and more particularly to the holder and dispenser structures of such devices.

In my copending patent application, Ser. No. 507,875 filed November 15, 1965, and entitled Method of Producing Stick-Type Applicator, there is disclosed a unique process for filling a dispensing container of the kind having a screw cap, wherein the viscous molten stick material is injected into the container through an opening in the cap while the latter is carried by the container.

The present invention solves the problem resulting from over filling or overspill in this type of dispenser construction, when and if this should occur during filling through the aperture in the screw cap.

Accordingly an object of the invention is to provide an improved holder and dispenser structure wherein filling is effected through the screw cap, which structure provides space to take care of overspill and eliminates the messiness caused by over-filling, thereby also elimimating the necessity for holding the filling charge to close volumetric tolerances.

Another object of the invention is to provide an improved holder and dispenser structure as above set forth, which stores and conceals any overspill which might occur, thereby eliminating clean-up operations normally due to overfilling.

Other objects of the invention are to provide an im proved holder and dispenser structure as above characterized, which may be economically molded of plastic substance in simple, inexpensive molds, which may be easily and quickly assembled, which is small, compact, reliable and foolproof in functioning, and which imparts a desired uniform configuration to the initially projecting portion of the stick material.

A feature of the invention resides in the provision of dual-plug or stopper means constituting part of the assemblage of the screw cap, which means simultaneously closes each of two axial openings of the cap body after the filling operation, one portion of such means simultaneously constituting the top wall of the cap body and enabling multi-color ornamentation and interchangeable name data to be readily utilized.

Other features and advantages will hereinafter appear.

In the drawings:

FIG. 1 is an axial sectional view showing a filled container ready for use and having a stick or bar substance such as a deodorant stick.

FIG. 2 is a top plan view of a filled container of FIG. 1.

ice

FIG. 3 is an axial sectional view of the container and ffileassembled screw cap body, in the process of being FIG. 4 is an exploded view of the container, showing the latter in section and with the screw cap removed, and further illustrating the advance or projection of the deodorant stick after it has been through a period of use and has become shorter.

FIG. 5 is a bottom plan view of a closure member for the screw cap, as used in FIG. 1.

Referring now to FIGS. l-4, there is illustrated a tubular container 10 which may be fabricated economically of plastic substance, said container having a cylindrical wall 11 and at its upper end external screw threads 12 disposed on a neck portion 14 which adjoins an annular exterior shoulder 16.

At its bottom end, the container 10 has an inner annular retainer flange 18 which defines a relatively large finger opening 20.

Adjoining the flange 18 is a manually operable plastic plunger 22 having an annular peripheral portion 24 engaged with the inner cylindrical surface of the container 10, said peripheral portion having a circular relief groove 26.

The plunger 22 has a socket or seat 28, in which one end of the stick deodorant material 30 is received.

In accordance with the present invention, a novel and improved plastic closure or screw cap assemblage 32 is provided, adapted to be carried by the upper end of the container 10 and to be unscrewed and removed when the deodorant stick is placed in use, said closure being especially organized to receive and contain any overflow which may occur from the filling process, and enabling such filling process to be effected through the bore of the screw cap.

As seen in FIG. 1, the screw cap 32 comprises essentially a cylindrical body portion 34 having a domed transverse apertured wall 36, and a separate plastic closure plug member designated generally by the numeral 38.

The body portion 32 has a bottom rim 40 of slightly enlarged diameter, having internal screw threads 42 which are cooperable with the external threads 12 of the container 10 for the purposes of removably carrying the screw cap on the container.

The transverse wall 36 of the screw cap is preferably of partially spherical shape, having a central filling opening 44 and an upstanding collar portion 46 adapted to receive the tip of a filling nozzle 48. The nozzle 48 may have the usual air vent opening 50 to provide for egress of air during the filling of the container 10 with the melted deodorant stick substance.

At its upper end, the cap body portion 32 has an internal annular shoulder 52 which is arranged to be engaged by a closure disk 54 0f the closure plug 38. Preferably also, the closure plug 38 includes a depending tapered separate stub 56 which is adapted to be received in the collar 46 of the transverse wall 36.

It will be understood that the closure plug 38 is initially removed from the cap body portion 34 for the purpose of admitting the filling nozzle 48 by which the deodorant stick material 30 is injected into the container 10'. Said stick material during the filling is in a heated, molten state, and as seen in FIG. 3 a predetermined charge of such material may be injected in the container 10 with the screw cap body 34 in place, that is, screwed onto the container 10.

During the filling operation any slight excess material, such as that indicated at 58 in FIG. 3, may be contained and carried by the upper chamber area 60 of the screw cap body 34.

After filling, and upon removal of the filling nozzle 48,

the closure plug 38 is merely applied to the screw cap body 34 of the filled container, such closure plug having a press-fit by virtue of slight interference dimensions in the diameters. The depending stub 56 of the plug may have a tight press-fit in the collar 46 and also the closure disk 54 may have a tight press-fit in the top rim of the cap body 34. If desired, a suitable cement may be employed in addition to the press-fit, or a sonic-welding procedure may be used to join the disk 54 to the side walls of the cap body 34. However, under normal conditions of use, the stated press-fit is satisfactory without additional securing means, since in the use of the article there are no forces tending to dislodge the closure plug 38.

After filling of the container 10 and applying of the closure plug 38, the article is ready for distribution and sale. The consumer, in placing the article in use, merely unscrews the screw cap assemblage 32 and applies the rounded end of the deodorant stick material 30 to the desired areas of the body. After continued use, the wear or consumption of the stick material is compensated for, by advancing the stick with finger pressure on the bottom plunger member 22, in the manner illustrated in FIG. 4, to advance the deodorant stick.

It will be understood from the foregoing that I have provided a novel and improved screw cap closure assemblage in combination with a container intended to be filled with viscous deodorant stick material, whereby the screw cap supplies a storage space for accommodating a slight amount of overfill of the material. The container is filled by the use of a filling nozzle applied to as to force the,

deodorant substance through a central opening in the screw cap, and after filling of the container and removal of the filling nozzle, the filling opening in the screw cap is closed and concealed by a plug member subsequently applied. The ultimate appearance of the screw cap is thus that of a solid object without filling openings, as may now be understood.

The provision of the upper chamber space 60 in the screw cap body 34 constitutes an advantageous feature, since it eliminates the presence of excess filling material at the filling station, which might otherwise cause a messy and undesirable condition.

The rounded shape of the wall 36 is imparted to the stick material 30, which becomes evidenced when the screw cap is first removed for use.

The plug 54 may have name indicia, and different brands may be indicated by the use of different plugs. Also, the plug 54 may have a contrasting color.

If the cap body 34 has an aging shrinkage which is slightly greater than that of the plug 54, the tight press-fit will be maintained.

Variations and modifications may be made within the scope of the claims, and portions of the improvement may be used without others.
