Patented Jan. 15, 1963 3,073,320 MAKE-UP KITS Donald A. Seaver, West Cheshire, Conu., assignor to Scovill Manufacturing Company, Waterbury, Coum, a
corporation of Connecticut Filed Juiy 9, 1959, Ser. No. 826,089 4 Claims. (61. 13279) This invention relates to make-up kits and especially to a tubular kit having a container for fluid material at one end with a closure cap carrying an applicator for such fluid material which is removable from the container with the cap. The cap may also carry an accessory tool projecting in the opposite direction from that of the applicator which may be surrounded by a removable cover so as to act as a handle in the use of the applicator. Also, when the accessory tool is used, the container acts as a handle for such tool.
One problem encountered with prior make-up kits of the above type is leakage of the volatile material in the container around the applicator and cap. In such makeup kits, an adaptor is inserted into the end of the container which serves to carry a rubber wiper ring surrounding the applicator and also has screw threads for the attachment of the cap.
Another problem encountered with such kits is that when the container and applicator are made of different metals which is desirable for reasons of appearance and cost; that is, when the container is made of brass and the applicator of aluminum, electrolytic action would develop between the two metals with the volatile material in the container serving as an electrolyte which after a time, would result in a leaky container. One of the objects, in addition to the seal normally provided between the wiper ring and the applicator, is to provide a second effective seal between the cap and the container so that any material which may escape under pressure around the wiper ring will, nevertheless, be confined. A further object of the container is to avoid any possibility of such electrolytic action.
Still another object of the invention has to do with ease and low cost of manufacturing, particularly of the assembly of applicator, accessory tool and cap which, for reasons understood in the art, will preferably be made of moldable plastic material.
A more detailed object of the invention is to provide an improvement in the adaptor and wiper ring assembly wherein a single cup-shaped piece of pliable plastic serves as:
. (l) A retainer for the wiper ring;
(2), A fluid-tight seal between the adaptor and the open end of the container; and,
(3) A separator of inert material preventing electrolytic corrosion as when the container is made of brass and the adaptor of aluminum.
Other objects and advantages will appear from the description of the preferred embodiment of the invention when considered in connection with the accompanying drawing, wherein:
PEG. 1 is a longitudinal vertical section through the make-up kit embodying my invention;
FIG. 2 is an exploded perspective view of the parts forming the adaptor and wiper ring assembly;
FIG. 3 is a similar view of the parts forming the cap and applicator unit;
FIG. 4 is an enlarged view ofthe adaptor and wiper ring assembly showing it in the process of being inserted into the open end of the container shell; and
FIG. 5 is a similar view showing these parts completely assembled.
Referring now to the drawing, the numeral 30 desig:
nates generally a make-up kit consisting of a container shell 11, an adaptor and wiper ring assembly 12, a cap and ap! plicator unit 13 having an accessory tool 14 (here shown as a comb) and a cover 15.
The cap and applicator unit 13 consists of a cap 16 carrying an applicator in the form of a cylindrical rod 17 which extends into the container shell 11 and wherein the inner end of said rod 17 is formed with a series of circumferential ridges and grooves indicated at 18, by which the material in the container is picked up and removed therefrom.
The container shell 11, preferably made of brass, is formed with a tapered rounded closed end 19 and an opposite open end 20. The material stored within the container shell 11 is often a volatile substance, such as mascara for eye make-up; therefore, it is important, when the cap and applicator unit is threaded into closed position, to provide sealing means which will insure against leakage when the kit is not in use or stored and to pervent deterioration and hardening of the material within the container.
The adaptor and wiper ring assembly 12 consists of a bushing 21, a cup 22 of pliable plastic material and an annular rubber wiper or O-ring 23. Specifically, the bushing 21 is made, preferably of aluminum, and is formed to provide a cylindrical plug end 24 projecting into the container, a circumferential shoulder 25 and an exterior threaded end 26 projecting outside the container, The bushing 21 is provided with a central opening 27 through which the applicator rod 17 is adapted to be inserted or removed. The lower end of the plug end 24 is provided with a counterbore or annular recess 28 in 'which the O-ring 23 is located. The plastic cup 22, in
its initial state before assembly, is best shown in FIGS. 2 and 4, as having an end wall 29 and a cylindrical wall 30. The end wall 29 is provided with a central aperture 29a to accommodate the adaptor rod 17 when passing therethrough. The outside diameter of the cup near the end wall 29 is somewhat smaller than the remainder of the cup for the purpose of guiding same in the open end 20 of the container shell during assembly. It is to be noted that the outside diameter of the bushing plug 24 is considerably less than the inside diameter of the container shell open end 26. l Also from FIG. 4, it will be noted that the over-all length of the cup wall 39 in its initial state is somewhat less than the over-all length of the plug end 24. The wall thickness of the plastic cup is somewhat greater than the annular space between the bushing and container wall. Therefore, it will be apparent that when the adaptor and wiper ring assembly 12 is forced into the open end 20 of the container shell 11, the wall thickness of the cup will be reduced and at the same time, the wall length will be extended thus filling the annular space between the plug end 24 and the container open end 20. From the above dimensional fits, it will be apparent that after assembly, the cup wall 30 will be under a constant compressive force, thus assuring an efiective seal between the open end 20 of the container and the bushing plug end 24.
Also, the wiper ring 23 is dimensioned to have a snug or binding fit around the applicator rod '17; the use of a rubber Q-ring assures the-ring will conform to any irregularities which may occur in the surfaces of the rod, thus normally effecting a seal at that point.
'It is to be noted from FIG. 5 that when the adaptor and wiper ring unit 12 is force-fitted into the open end 20, it is driven to a position where the upper surface of the bushing shoulder 25 is positioned a noticeable distance below the terminal edge of the shell open end 20 thus leaving the edge of the shell exposed as indicated at 31 for reasons which will appear later.
Also in FIG. 5, it is to be noted that the outside diameter of the bushing shoulder is slightly less than the inside diameter of the open end 20 and by reason of the compressed cup wall 30, said shoulder will be centralized relative to said open end so that no part of the bushing will contact the container shell. This is desirable when the container shell and the bushing are made of different metals, such as brass and aluminum, in order to avoid any electrolytic action from developing which would set up a corrosive action between the assembled parts.
Considering now the constructural details of the cap and applicator unit 13, the cap 16 is preferably made of a pliable plastic material, such as polyethylene, and is formed with a larger cylindrical section 32 and a smaller cylindrical section 33. The larger section 32 is provided with an interior threaded recess 34 which engages with the bushing threaded extension 26 for removably joining the cap and applicator unit 13 to the container shell 11. The smaller section 33 is provided with a socket with in which is received a cylindrical connector portion 36 that integrally joins the accessory comb 14 to the applicator rod 17 together in alignment and on opposite sides thereof. A central passage connects the cap threaded recess 34 to the socket 35 for receiving the applicator rod 17 therein. The cylindrical connector portion 36 is formed with a circumferential recess 37, and the socket 35 of the cap smaller section 33 is formed with a complementary inwardly extending rib 38.
In assembling the applicator tool to the cap 16, the applicator rod 17 will first be inserted through the cap central passage 40 and finally the cylindrical connector portion 36 will be forced into the socket 35. Due to the fact that the cap 16 is made of pliable plastic material, it will be understood that the wall of the smaller diameter section 33 is of sutficient resiliency to permit the leading end of the cylindrical connector portion 36 to be forced past the rib 38 until the latter aligns with the connector recess 37 and there snaps in place to hold the applicator tool and cap 16 together as a unit.
When the cap 16 is assembled to the bushing threaded extension 26, the exposed annular edge 31 of the shell 11 will abut against the adjacent surface of the cap 16 which projects over the shell. Thus, the metal edge will seat itself into the pliable plastic material of the cap and assure against any possible leakage of material which might escape past the wiper ring 23 or around the plastic cup 22.
FIG. 1 shows a metal sleeve 39 surrounding the larger section 34 of the cap 16. While this sleeve may incidentally serve as a decorative piece, its primary purpose is to strengthen that portion of the cap 16 surrounding the interior threaded socket 34 and prevent the threaded extension from stripping out in case abnormal tightening pressure is applied to the cap 16 when assembling it to thecontainer shell 11.
While only one form of the invention is disclosed, it is to be understood that various modifications may be made in the invention without departing from the spirit of the following claims.
