9 Claims.

The present invention relates to closures for liquid containers such as bottles and Jars and the primary object of the invention is to provide a dispenser cap or closure for liquid containers which normally forms a closure for the container and is capable of being temporarily distorted at one portion so as to open a passageway and permit pouring all or any desired portion of the liquid contents of the container.

A further object of the invention is to provide a moulded, one piece dispenser cap for liquid containers, having a novel vent passageway arrangement whereby the container will be properly vented when a portion of the cap is distorted to open a passageway therethru.

A further object resides in the novel shape and construction of the dispenser cap whereby the cap will retain its general shape against collapsing when one end portion thereof is distorted to open a pouring passageway.

A further object is to provide a dispenser cap which may be readily applied and removed from a bottle or jar, and which maybe easily opened by exerting a slight pressure upon opposite sides of the cap adjacent the discharge end of the cap.

Other objects and advantages of the invention will be apparent from the folowing detailed description taken in connection with the accompanying drawing, forming a part of this specification and in which drawing:

Figure 1 is a top plan view of the cap or closure shown applied to a bottle.

Figure 2 is a side view of the cap attached to a bottle and in its normally closed condition.

Figure 3 is a view similar to Figure 2 but showing a fragmentary portion of the mouth or discharge end of the cap in section and opened.

Figure 4 is an enlarged longitudinal section thru the cap applied to a bottle.

Figure 5 is an enlarged transverse section on the line 5-5 of Figure 2.

Figure 6 is an enlarged transverse section on the line 6-6 of Figure 3.

Figure '7 is a top plan view showing a slightly modified form of closure cap.

Figure 8 is a longitudinal section thru the cap shown in Figure '7.

Figure 9 is an enlarged transverse section on the line 9-9 of Figure 8.

Referring to the drawing in detail and wherein like reference characters designate corresponding parts thruout the several views, the form of dispenser cap A disclosed in Figures 1 to 6 inclusive is preferably moulded in one piece from rubber and is substantially of L-shape in formation,

The dispenser cap A in the example illustrated is in the form of a spout designed for attachment to the neck of a bottle B, altho it is to-be understood that the attaching end of the cap may vary slightly in shape and size to permit attachment of 5 the cap to jars or any other liquid container to form a normally closed dispensing cap therefor. The cap A embodies a hollow arcuate-shaped intermediate or body portion I0 having walls of uniform thickness and being of a relatively hard 10 rubber as indicated by the heavy section lines in Figure 4 whereby the intermediate portion i0 is sufliciently stifl so as to retain its shape against collapsing. This elongated body portion [0 preferably tapers towards its outer end, the inner or 15 bottle attaching end of the body being of circular formation and gradually running into oval-shape at the outer or discharge end of the body. i

Formed at the inner end of the body portio i0 is a tubular coupling or attaching portion ll 20 adapted to snugly engage over the neck of the bottle B and provided at its open end with a retaining bead or ring I! adapted to engage in an annular external groove on the bottle neck to securely retain the cap against displacement. Provided in the coupling portion II at its point of juncture with the body portion i0, is an internal rest ring or stop flange i4 forming an abrupt shoulder which engages upon the end of the bottle neck and limits movement of the attaching portion over the bottle neck. The attachin portion H is of a relatively softer rubber than that of the intermediate body portion l0 so that the portion I I may readily yield to permit attachment and removal of the dispenser cap from the bottle.

The outer oval-shaped end of the body portion ID has formed thereon, a hollow oval-shaped head portion l5 formed of a relatively softer rubber than that of the body portion In where- 40 by this head portion may be readily distorted to open a normally closed passageway therethru. This head portion I5 is formed with a companion pair of flat lips it which are normally held in close contact with one another providing a slit between the lips which may be opened by pressure exerted upon the head at opposite ends of the slit. The head portion I5 is provided at its inner end with a pair of stiffening ribs I! which extend transversely of the head along the inner portion of each lip l6 and have their ends tapering off and terminating in shallow recesses l8 formed diametrically in the head portion. These recesses it provide gripping points for the thumb and forefinger whereby whenapressureisexertedupontheheadatthe recesses II, the ribs 11 will be spread apart at their intermediate portions as shown in Figure 6 and cause the flat lips II to spread apart and form an opening therebetween providing a passageway for escape of liquid from the bottle. Upon releasing pressure at the ends of the ribs i I, the lips I! will automatically close upon one another as in Figure 4. The ribs II will not only provide a stiffening means for the head ll, but also serve to return and retain the lips It in closed engagement upon one another by normally exerting a pulling action upon the ends of the lips tending to lengthen the lips.

. Extending along the longitudinally concaved inner side or the intermediate body portion I is a hollow venting rib is providing a vent passageway II for admitting air into the bottle while the liquid is being poured. This hollow venting rib is is open at both ends and has its inner open end terminating in slightly spaced relation above the stop flange ll whereby the inner end of the vent passageway will not become closed when the cap isapplied to a bottle for use. The outer open end of the venting rib ll terminates just inwardly or the closure lips I whereby the cap is airtight when not in use.

The venting rib I! is of a relativeLv hard rubber similar to that of the intermediate cap portion III to prevent collapsing and closing of the vent passageway 20. The outer end portion of the venting rib, where it extends between the stiflening ribs I1, is preferably of the relatively harder rubber on its inner half as shown more clearly in Figures and 6 so that this outer end portion of the venting rib will not be collapsed and close the vent passageway when the outer end of the cap is distorted for opening the lips I.

Thus it will be seen that by having the intermediate body portion I ll of relatively hard rubber of a substantially rigid character, the cap is retained in proper shape and against collapsing, and by having the ends of the cap of a relatively softer rubber of a yieldable character, the end portion ll maybe readily and easily applied to a bottle, while the outer end or head portion i5 may be readily distorted to open the lips I.

In the form of the invention disclosed in Figures 7, 8 and 9, the dispenser cap C is moulded from rubber of a flexible character and is also substantially L-shape in formation like that of the cap A. The cap C embodies a hollow arcuate-shaped intermediate or body portion l0 formed at its inner end with a tubular coupling or attaching portion ll having the retaining head or ring i2 and the internal stop flange l4. The outer oval-shaped end of the body portion II is formed with the head l5 provided with the pair of flat lips it which normally contact one another to close the outer end of the cap. The head It is also provided with the transverse stiifening ribs ll' terminating at their ends in recesses ll. A hollow venting rib l9, providing a vent passageway 20', extends along the longitudinal concaved inner side of the body it with its inner end terminating adjacent the stop flange l4 and its outer end terminating just inwardly of the lips l6.

Embedded in the intermediate or body portion II and extending longitudinally thereof, is a suitable' number of stiffening wires 22 which serve to retain the shape of the portion Ill and prevent ready collapsing thereof. These stiffening wires 22 have their ends terminating in slightly spaced relation to the stop flange I4 and the stifleninggribs l1 whereby the end portions of the cap n iay readily yield for accomplishing their intended functions.

' Thus, in both forms of the dispenser caps A and C there is provided an intermediate or body portion which is sufllciently still! to function nicely as a cap of predetermined shape and provided at one end with a flexible portion for ready attachment to a bottle or jar and at its opposite end with a flexible head portion having lips which may be opened by distorting the head portion.

With a dispenser cap of the specific shape shown it will be seen that liquidv when poured from the bottle will flow along the longitudinally convexed inner side of the cap and will not enter and prevent proper functioning of the vent passageway extended along the longitudinally concaved inner sic'e of the cap.

Changes in details may be made to the forms of invention herein shown and described, without departing from the spirit of the invention or the scope of the following claims.
