'7 Claims. 1
"This invention relates to closures and in par ticular to closures for containers of volatile fluid such as lighter liquid and spot remover.
It has been a practice heretofore to supply such volatile fluids in a type of small metal container containing four fluid ounces having an apertured flat top and an upstanding metal neck with an external circumferential groove. The groove is designed to receive the metal depending skirt of a spout type metal closure element, the closure applying operation being accomplished, for example, by a so-called Callahan capping machine, which squeezed the closure skirt circumrerentia'ny and caused the metal of the skirt to press or flow into and fill the external groove of'th'e can neck. This operation would frequently produce a satisfactory hermetical "seal between the spout skirt and the can neck, but due to the rigidity and inherent lack of resilience in the parts constituting this metal to metal seal, subsequentyibration or .joltihg in normal shipping or handling too frequently disrupted the sealing connection and thus permitted the inflammable fluid contents of the canto escape. The hazards of this conventional closure became well-known and damage experience became s'ufiiciently important as to create serious insurance, safety and indemnity problems.
"This artof closures for fluid containers is characterized by large volume and small unit value, hence solution of the fundamental problem, that is, how to maintain the durable and effective seal between spout skirt and can'neck, necessarily was accomplished within narrow cost limits for material, labor and equipment and, oicourse, the ideal sbliition would be eliminating the difficulties in such'ma'nner as to enable the use of pre-exi'stent equipment.
It therefore an object of the present invention speedily and economically to provide a tight and durable seal between can and spout.
'It is another object of the invention to provide a plastic spout to fit around the outside of the can heck.
it is another object of the invention to provide ablastic cap for the plastic spout Which Will .fiiovide an efiicient closure for the spout after the latter has been opened.
It-is another object of the invention'to prov de a plastic spoilt With a lengthened skirt to facilita'te the capping peration.
'It is another object of the invention to provide a plastic spout design which maybe made up in colors corresponding to or contrasting with the colors of the can.
another 'obiec't 6f the invention to provide 2 a closure element for containers of inflammable fluids comprising plural plastic elements which may be similarly or difierentially colored, respectively.
It is also an object of the invention to .Iiiovide a spout design which willpr'event leakage without requiring modification of the standard can neck and is adapted for convenient use in the conventional Callahan capping machines and other machines of 'stanqa'rd type and practice.
The above and further objects of the invention will be understood 'by referring to the following detailed description read in connection with the ac ompanying drawings wherein I Fig. 1 is a fragmentary eiip'loded view showing the can and completed closure, with the plastic spout tap; a
Fig. 2 shows an ehlai'gd i/eitibal section of the can spout and spout tap after assembly and before opening;

Fig. 9 is 'a schematic view in elevation showing method for attaching the plastic spout to a plurality of cans simultaneously;
Fig. 10 is an end elevation of the mechanism shown in Fig. '9; I
11 is an emerged detail showing another mechanism for applying the plastic spout to the can, this being designed primarily for individual manual operation; and i Fig. 12 is a perspective view of -the pressure plate shown in Fig. 11. v
Referring to the drawings wherein identical parts are indicated by similar referent:e'iiuinerals, the metal tan it for lighter fluid or spot remover has a metal top 20 surmounted by a plastic spout or cap 2| constituting important aspect of the invention. Spent '21 has a'base -2'2 and upwardly a finish lobe '23 formed in the molding process. The finish lobe "23 is formed integrally with the spout 2| and is abruptly reduced in section at the unction thereof with thespout'fl forfaci li tat'iii'g the severance of the finish Io'be from the plastic spout. It will be understood thatthe finish lobe is readily separable by a knife or with the fingernail when it is desired to open the container sealed in the practice of this invention. A plastic cap 24 surmounts the spout and protects lobe 23 before opening and seals the spout against accidental spillage or leaking after opening.
The details of construction of the present cap are particularly shown in Fig. 2 wherein top 20 of can l9 has the usual aperture 25 communicating with upstanding neck 21 the latter having a circumferential groove forming an upper annulus 29. Spout 30 is preferably made of colored plastic of such a composition that it is flexible, proof against deterioration or dissolution by volatile or corrosive liquids and possessed of a greasy surface feel, the latter being of particular interest in that it facilitates the placing of the spout on the neck to seal the can as hereinafter described.
Spout 30 has a skirt 3! depending from base 22, such skirt, it being important to note, is at least one-sixteenth of an inch longer than previous spouts, the purpose or this additional length being to aid in uniting the cap and the neck. The skirt provides additional material so that the operator may place the spout on the neck of the can prior to subjecting it to the capping machine and the spout-mounted can may then move along the assembly line or link belt without being accidentally dislodged. The purpose of providing the additional length on the skirt 3! at least i% of an inch longer than previous spouts is to insure, by the resilient nature of the plastic material forming the spout, a snug engagement about the neck of the container below the sealing ring 39. That is to say, if the sealing ring 39 has moved to a position engaging beneath the beaded neck of the container the cylindrical skirt extends a sufiicient distance to establish a snug contact with the smooth exterior wall of the neck. Thus the resilient interior surface of the cylindrical part of the neck serves initially to position the spout on the neck of the container while the container is being moved along the assembly line as part of the process in applying the spout to the container, and thereafter the resilient interior wall serves to grip and maintain the spout in fixed position on the neck with the triple seal effected between sealing ring 39 and the exterior of the neck of the container; between the sealing shoulder 40 and the top of the neck of the container; and the seal effected between the resilient ring 44 and the interior of the neck of the container. The fact that the plastic material from which the spout is formed is resilient in nature insures yieldability of the sealing portion sufficiently to effect a dependable fluid tight closure. The relatively short skirt of conventional spouts is wholly inadequate for effecting the type of seal accomplished in the closure of my invention. Moreover, a spout formed from metal, such as lead, does not possess the quality of resiliency possessed by the plastic material from which the spout of my invention is formed, so that such metallic or lead spouts have necessitated additional operations thereon for effecting a seal. Such operations are unnecessary in applying the plastic spout of my invention.
Referring again to Fig. 2, spout 30 has a flat top or upper surface 32 which is useful in applying the cap to the neck during the closure operation.
Angle 33 between tapering spout 30 and flat top 32 may, of course, be arbitrary within limits of the art but its relation to angle 35 determining the inclination of the sides of cap 24 must be such that the inner wall of cap 24 when inserted firmly on the spout 39 will tend to bind thereto and thus prevent leakage after the spout has been opened as in use. For example, angle 33 may be 100 and angle 35 may be 95.
Externally the plastic cap 24 has vertical grooves which strengthen the structure, impart a pleasing ornamental appearance thereto and aid in the molding process and the means of plastic injection which may be used in manufacture of cap 24.
The spout 38 is provided with a continuous recess 31 extending axially thereof. At the bottom the spout skirt 3| is preformed to have an internal integral annular sealing ring 39 for snugly connecting in groove 28 in neck 21. In this assembly inherent possibility of dislocation or breaking of the seal by vibration or accident is very slight due to the resilient nature of they plastic material employed in forming of spout 30 and due to the particular construction of the cooperating parts as illustrated. Top 32 of the spout is provided on its undersurface with a supplementary sealing shoulder 40 which closely engages the top of the neck 21 and concentrically with an inner and longer supplementary sealing shoulder 4! which extends into the neck aperture to provide a third sealing agent.
It will be apparent from the above that the space relation between preformed sealing ring 39 and the concentric and cooperating supplementary rings 49 and 4| must be such that the fitting of sealing ring 39 into groove 28 of the neck pulls the supplementary sealing rings under tension to bear closely upon the respective adjacent portions of the neck structure. From the foregoing it will be apparent that spilling is pre-' vented by ring 4| which prevents the fluid from emerging from the neck. Any slight amount to escape is prevented from flowing over the top of the neck by ring 40, and a final hermetical seal is provided externally of the neck by the intimate placement of plastic sealing ring 39 in metal groove 28.
The invention described not only provides a perfect seal to protect against subsequent leakage,
damage and indemnity problems but the structure is so designed as to be economical and conveniently attachable by conventional mechanisms, or manually.
A simple method for applying the spout to cans is indicated in Fig. 5 which utilizes the split pulley shown in Fig. 3. As indicated at the left in Fig. 5 the cans are subjected to a split pulley press or corking wheel 43 comprising opposed rims 44 and 44a which by engaging the upper surface of base 22 of the spout press the latter downwardly in intimate sealing contact with the neck of the can. The cans are carried upon a link belt conveyor 45 having clamps 46 thereon for holding the cans in spaced relation. When electric motor 41 is actuated to drive the pulley 43 in a counter-clockwise direction and the link belt conveyor in a clockwise direction capping and sealing proceeds rapidly, it being only necessary that the operator repeatedly place cans in the clamps 46 at the left of corking wheel 43 and then place the plastic cap with the lengthened skirt upon the top of the neck of each can before it is advanced rightward to the cork ing wheel. As will be apparent in Figs. 3 and 4 the split pulley or corking wheel 43 does the rest. In Fig. 3 the spout rests upon the neck befor receiving the pressure of the wheel. In Fig.
5. a the spout is subject to the wheel which dbwnwa'rdly on the spout to cause sealing ing 38- to press outwardly over neck an'n 2 9 thereafter snapping into sealing positionin groove 28 as shown in Fig. 2. a 3 another mechanism shown Fig. f7 a convenient adapter 48 is provided for use" inth'e Callahan capper. By removing the conventional clincher head on the Callahan capper it is possible to use a piece of steel rod 48 threaded at 49 on its upper end 5| with corresponding SAE thread that will fit the Callahan capper fragmentarily shown at 50 in Fig. 7. A short piece of one-half inch inside diameter pipe 52 welded to this steel rod and then either flanged out slightly as shown at 53 or built up slightly with weld may be used, the fianging out being described to prevent cutting action when the capper head is depressed on the spout. When the spout is set lightly on the can and placed under the capper head, depressing the latter completes the seating action of the plastic spout which cooperates with the can neck as shown in Figs. 4 and 2.
Another mechanism by which the invention may be practiced is shown in Fig. 9 for filling multiple cans simultaneously, twelve being illustrated. The cans may be placed on a tray 55 having suitable frames 56 and the press provided with a two inch square steel 5! drilled large enough to accept one spout in each hole. The steel is provided with holes 59 and attached to head 60 by screws 6|. The press 63 has hose 64 connecting to control mechanism (not shown). As shown in Fig. 10, suitable brackets 65 and 85a may be used to fix the press to any sturdy upright support or body 61.
A manual capper of simple design is shown in Figs. 11 and 12. This may be used for individual capping in sequence and is utilized manually. The manual capper comprises a base plate 69 having guide track 1| at one end and spaced support bolts 7212 at the other end and spring plate 13. Plate 13 has at one end holes 15 for the spaced bolts and at the other end is bifurcated to provide parallel fingers I1 and 11a having space 19 therebetween through which the spout may be advanced. Fingers 11 and 11a are curved upwardly at 80, see Fig. 11 so that when the can with mounted spout is moved to the left with the spout between the fingers 11 and Ha, the curvature of the spring will depress the spout to cause its inner rings to engage the neck of the can in useful hermetical seal.
A preferred type of material for the plastic is polyethylene, commonly known in the trade as polythene and the cap is molded under a pressure of the order of 13,000 lbs. per square inch (guage press of 600-700#) at a temperature of 100 F. The injection and gating may be done from the small end of the spout.
