Description

A g- 9, 1956 s. SCHWARTZMAN SPIN WELDED PACKAGE Filed April 2, 1964 gm: 6% M INVENTOR. 4% 552/ J'dfiW/VETZMAA/ FIG.4
R 3,264,676 Patented August 9, 1966 3,264,676 SPIN WELDED PACKAGE Gilbert Schwartzman, 20 Wilmot Circle, Scarsdale,
Filed Apr. 2, 1964, Ser. No. 356,838 1 Claim. (Cl. 15-569) This invention relates to a fluid applicator and especially to a spin welded package for containing and for use in applying shoe polish, cosmetics, other fluids, medications, or for serving as a marking device.
An object of this invention resides in the provision of an applicator in the form of a cylinder having integrally formed therewith means for holding a fabric dauber head on the container while also having a base fused to the cylinder to form a container for various types of liquids including, but not necessarily limited to, shoe polish, marking inks and pigments, cosmetics and medications.
Another object of this invention resides in the provision of means for facilitating the application of cosmetics, medications, shoe polish, other fluids, or the like from an applicator having a dauber integral therewith.
In the past daubers have been constructed which are provided with projecting portions which are inserted in the necks of containers. These projecting portions have all been of reduced cross sectional dimensions to allow for proper construction and operation of the valve assemblies of these daubers. The containers used with such projecting portions have necessarily been constructed with elongated necks. Modern packaging techniques and styles are eliminating such containers with elongated necks in an attempt to render packages more space saving, compact, streamlined and eye appealing. Further, in modern packaging there is an ever increasing use of various synthetic plastics such as polyethylene and polyurethane for the production of substantially unbreakable containers.
Accordingly, it is another object of this invention to provide an applicator having a dauber which eliminates the necessity for a container having an elongated neck thereby saving on material costs.
It is highly desirable that packages for shoe polish, various medications, and cosmetics be spillproof and leakproof because of the permanent stains that can result if the material in the packages is released due to accident or inadvertence. Accordingly, it is an additional object of this invention to provide a spillproof, substantially shatterproof, leakproof unitary applicator which can be easily assembled and filled.
A further object of the invention is to mount a valve assembly within a container to form an applicator in a manner so as to seal the container so that liquid can pass out of the container only through the valve assembly, yet which applicator is of a construction to permit easy filling thereof even after complete assembly.
An additional object of this invention is to provide a container formed of synthetic plastic materials including a base having inner and outer flanges for receiving the lower edge of a cylinder for not only insuring a leakproof spin welded connection between the base and cylinder, but which flanges provide for a weighted bottom having an enlarged supporting surface thus allowing the material of the base to serve a plurality of purposes.
A yet further object is to provide an applicator which includes a base capable of being spin welded to a cylinder after a valve assembly has been inserted into position for controlling fluid flow out of the container.
Still another object of the invention resides in the provision of a valve assembly for a fluid applicator that is held in place by an integral portion of the container being swaged over a ring of the valve assembly in a convenient manner allowing for high speed mass production.
Still further objects and features of this invention reside in the provision of a dauber which is inexpensive to manufacture, simple to use, capable of metering fluid of various viscosities in an effective manner so that the dauber is especially adapted for use in applying shoe polish, medications, cosmetics, oils, polishes and the like, and which dauber may be made in any convenient size as desired.
These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this dauber, preferred embodiments of which have been illustrated in the accompanying drawings, by way of eX- ample only, wherein:
FIG. 1 is an exploded vertical sectional detail view of an applicator constructed in accordance with the concepts of the present invention;
FIG. 2 is a vertical cross-sectional view of an applicator in an assembled condition and illustrating the valve assembly in a closed position;
FIG. 3 is a top plan view of the container utilized in the applicator with a portion of the cover being broken away showing details of the valve assembly;
FIG. 4 is a partial sectional view of the applicator taken along the plane of line 44 in FIG. 3, shown in an operating position with the valve open; and,
FIG. 5 is a perspective view of the applicator with the cap removed to show details of the applicator.
With continuing reference to the accompanying drawings, wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 is used to generally designate the fluid applicator comprising the present invention. This applicator includes a cylinder 12 having a retaining ring 14 integrally molded therewith. The cylinder 12 may be formed of polyethylene, polyurethane, or other suitable synthetic plastic materials. The retaining ring 14 includes a flange 16 provided with a swaged lip 18 for retaining a fabric cover 20 in position between the lip 18 and a rib 22 of circular configuration.
The cover 20 is constructed of two layers, the upper layer 21 of which is formed of a nylon knitted brushed fabric so as to achieve a felt-like applicator surface and appearance, while having the chemical inertness and strength of the nylon. Laminated and bonded to the nylon knitted brushed fabric is the lower layer 23 of coarse polyurethane foam.
The cylinder is provided with a groove 25 therein into which the rib 27 on a cap 26 is adapted to be inserted. The cap 26 may alternatively be threadedly detachably secured to the cylinder 12. The cap 26 is provided with detent means 19 for facilitating removal thereof and is of any desired ornamental exterior configuration.
The retaining ring 14 includes a web 31 having an arcuate tapered opening 28 therein. Cooperating with the arcuate tapered opening 28, which serves as a valve seat, is the conical surface 30 of a molded valve head 29 forming a part of an integral molded plastic valve assembly 24. The valve assembly 24 further includes a spring 32 formed in helical strips, the lower portion being integrally formed with an enlarged circular mounting ring 34. The mounting ring is held in place within a tubular projection 42 extending a short part of the length of the cylinder 12, which projection is swaged at its lowermost end to hold the ring 34 with spring strips 32 always under at least some compression. The other end of the spring 32 engages the valve head 29 and thus the spring 32 which is in a continuously stressed condition under compression will continuously urge the valve head 29 into and through the opening 28 and against the valve seat for the purpose of closing the opening and preventing 3 fluid flow from the cylinder 12 into the space between the web Sland the cover 20.
The cylinder 12 is closed in a fluid tight manner by the base 60 including a disc 61 which hasintegrally formed,
therewith a pair of spaced cylindrical flanges 62 and 64 defining a recess 66 for receiving end 68 of cylinder 12. The base 60 isispin welded to the cylinder with the flanges 62 and 64 being integrally fused with the'cylinder end 68 to form a Weighted bottom for the applicator because of the mass of flanges and end 68. Further, the bottom is of a highly ornamental appearance while providing an enlarged supporting surface.
In' use the applicator is urged against a surface. The,
cover 20 pushes againstvalve head 29 opening the valve and allowing fluid in the container to flow outwardly.
The container is filled by using a hollow needle which i is urged through cover 20 and through opening 28 after depressing valve head 29.
A latitude of modification, substitution and change :is t
intended in the foregoing disclosure, and in ,somesyinw stances, some features of the invention Willbe employed 1 without a corresponding use of other features. Accordingly, it is appropriate that the appended claim be construed broadly and in a manner consistent with the spirit and scope of the invention herein.
