BOTTLE CAP I* Filed Oct. 5l 1942 Y llv INV ENFOR. i
Patented July 23, 3946 l 2,404,110 .i BOTTLE CAB Thomas R. smith, Newton, Iowa, assigiior to The Maytag Company, Newton, Iowa., a corporation of Delaware Application October 3, 1942, Serial No. 460,638
2 Claims.
The present invention relates to bottle caps and more particularly to a novel form of closure which may be readily removed and replaced as often as found necessary or desirable, and when replaced effectively seals the contents of the bottle.
Among the objects of the presentrinvention is the provision of a novel replaceable cap or closure in which the sealing effect isV independent of the tightness of the cap and whereby the cap or closure need not be screwed down tightly in order to obtain a perfect seal. This provides a considerable advantage over prior types of caps now' being used upon various forms of bottles, such as catsup bottles and the like, in which the screw caps must be tightly screwed down in order to effectively seal and preserve the contents of the bottle.
Further objects are to provide a construction of maximum simplicity, efficiency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.
The invention further resides in the construction, combination and arrangement of parts illustrated in the accompanying drawing, and while there is shown therein a preferred embodiment, it is to be understood that the same is susceptible of modification and change, and comprehends other details, arrangements of parts, features and. constructions without departing from the spirit of the invention. l
In the drawing: i
Figure 1 is a View, part in side elevation and part in vertical cross section, showing the novel cap or closure applied to a bottle.
Figure 2 is an enlarged fragmentary view in vertical cross section showing the novel sealing ring and its application to the cap.
Figure 3 is a fragmentary view in Vertical cross section of an alternate form of seal.
Referring more particularly to the .disclosure in Figures 1 and 2 of the drawing, the embodiment therein selected to illustrate the invention comprises a bottle I of any suitable design or configuration, a cap or closure 2 and a sealing ring 3 mounted or received within-an annular substantially V-shaped groove or recess 4 formed within a depressed, centrally disposed portion 5 of the cap.I This depressed portion is adapted to depend into the neck 6 yof the bottle with the base or outer surface 1 of the seal 3 in contact with the interior surface of the neck of the bottle.
is preferably formed with a threaded flange 8` adapted to threadedly engage with complementary threads 9 formed on the exterior surface of the neck of the bottle. This permits the novel cap or closure to be employed upon the ordinary or standard types of bottles now in general use for containing catsup, syrup, etc.
As more clearly shown in Figure 2, the groove or recess 4 is of substantially V-shape with the base I0 rounded and the side walls II diverging at an angle of approximately The seal or sealing ring 3 is of substantially wedge-shape with its Vertex I2 curved upon a radius preferably slightly less than but substantially conforming to the radius of the base IIJ. The opposite sides I3 of the seal are disposed at an angle of approximately 45 whereby to permit the seal to pivot within the groove or recess for most effective sealing contact of the base or outer surface I of the seal with the interior surfacey of the neck of the bottle. This base is curved or roundyshape and mounted within a substantially channel-shaped groove or recess I'I in the cap or closure I8. This groove or recess is formed of. a width greater than and of a depth somewhat less than the diameter or cross section of the sealingrring, whereby the exterior surface of the ring applies and maintains a predetermined amount of compression and sealing effect against the interior surface of the neck 6 of the bottle I. In other respects the cap or closure is similar in construction to that shown in Figure 1.
Having thus disclosed the invention, I claim:
1. A bottle cap providing a closure for a bottle and having a threaded portion for engagement with threads on the exterior of the bottle, comprising ay cap member having a centrally depressed portion adapted to extend into the neck of the bottle, an outwardly opening substantially V-shaped recess formed in the depressed portion, and a resilient sealing ring of substantially wedge-shape in cross section carried in the recess `with its outer end rounded and adapted to Vhave Wheneverfthe capis mounted on the bottle.
2. In .combinations bonne provided' .with f" threaded neckfa threaded cap forming a. closure' for the neck and provided with a depressed central portion adapted to project into the bottle,"
invand to either side Yof the recess.
an outwardly opening substantially V-shapedrrela cess provided in the depressed portion and' a resilient sealin'igring having dii/erging side walls forming an acute angle, a reduced and rounded inner end pivotally seating inthe base of the recess and a relatively wide and rounded outer end forming a sealing face projecting beyond the confines of the recess and into sealing Contact WithhvtheV interior surface of, the Aneck of the bott1e`jthefside walls'v of theI ring being"disposed at an angle` substantially less than theangle formed Y by the side Walls of the recess and spaced there- 'from suiicient to permit the ring to pivot With-
