(croi- 614) 6 Claims.
This inventionrelates to liquid dispensers and more particularly to a novel form of the closure in such dispensers.
In dispensers of the type to which the invention relates, a bottle or other container containing adhesive or similar material in liquid form is mounted in an inverted position ready for manual actuation toward a dispenser base upon which the sheet or surface to be treated is placed. vAn example of such a mounting is shown in my copending application, Serial No. 325,227, filed March 21, 1940. 4Such adhesive dispensers present a special problem in the provision of a suitable closure, for inasmuch as the container is normally in an inverted position, the cap must provide an effective seal to prevent leakage of the adhesive from the closure and the container when the dispenser is not in use, or hardening or oxidation therein, but must nevertheless be capable of permitting the flow of the adhesive, at a suitable rate from the closure immediately upon contact thereof with the sheet or surface to be treated without leakage or dribbling thereafter.
It is among the important objects ofthis invention to provide a liquid dispenser having the aforesaid characteristics and yet being of simple, compact and inexpensive construction involving a minimum number of parts all of durable materials. In the preferred embodiment of the dispenser, as hereinafter disclosed, this closure comprises a cap of rigid material as metal adapted to be attached to the container and a single integral deformable elastic or resilient member as rubber which coacts with the cap to perform all the functions above indicated. Y
Further objects of the present invention will become more apparent from a consideration of the following detailed description taken in conjunction with the accompanying drawing which shows a central vertical section through an adhesive-dispensing container provided with a closure constructed in accordance with the `present invention,
Referring to the drawing, reference numeral I indicates a bottle or other suitable container having a reduced neck portion 2 and a relatively thick, externally-threaded annular lip 3. This lip has a boss 4 surrounding the orifice of the container, leaving a depressed or shouldered portion 5 adjacent the upper external circumference of the lip. An integral member 6 of deformable elastic or resilient material, as rubber, is provided with a boss l adjacent its outer circumference which boss is adapted to seat upon the'shoulderedV portion 5. The member 6 has an intermediate disc section with perforations 8 extending therethrough, and a raised boss 9 projecting centrally therefrom on the side opposite the annular boss l. A cap Ill of metallic'or other rigid material is provided with an internally screw-threaded cylindrical portion I'I adapted to engage the externally screw-threaded portion oi the lip 3, and a flat shouldered portion I2 adapted to press against the flat outer face of the member 6 and force the boss l into tight huid-sealing `contact with the lip of the container. The central part of the cap I0 projects outwardly to form a funnel-shaped portion I3, which terminate's in an opening I4 through which the outer end or tip 9' of the boss 9 projects. This outer end of the boss isrconical to conform to the slope of the funnel-shaped portion I3, and it provides a surrounding channel I5, open to the container I through the perforations 8 and normally containing a limited quantity of adhesive in close proximity to the orice I4.
Y When the dispenser'is not in use, the conical surface of the boss '9 is pressed rmly against the inner surface of the funnel-shaped portion I3 to forma tight closure for the container and effectivelyv prevent any leakage or dribbling therefrom, and also to prevent hardening or oxidizing of the adhesive therein. It will be observed that the weight of the adhesive within the container, together with the natural elasticity or resilience of the member 6, tends to force the boss 9 into aposition tightly closing the orifice -I4 and with the tip 9iI extending therethrough.
When it is desired to apply the adhesive, the container'is' lowered and the tip 9 is pressed against the point or along the surface to which the adhesive" is to be applied. This presses the boss 9 inwardly permitting an immediate flow of adhesive through the orice I4 from the limited quantity in the channel I5, which quantity is quickly replenished from the container I.
Where the container is normally supported with the cap down in the manner disclosed in my copendingapplication above mentioned, an orifice I6 may be provided in the base of the container to admit air to the space above the surface of the adhesive in the container, thereby permitting the fluid to ilow readily when the orifice I4 is opened in the manner above described. Also the bottle may then be filled with liquid through the opening I6. It will be understood, however, that the dispensing cap herein disclosed also possesses utility when used with a container that is normally supported in upright position, in which case the opening I6 is omitted.
From the above description it will be seen that I have provided a dispensing cap for adhesive or similar materials in which a single member 6, l, 9 with perforations 8 provides a valved closure of the dispensing orifice and at the same time provides a liquid-tight seal for the rim or lip of the dispensing container. The use of separate springs for pressing the valve in the closing position is .avoided land likewise separate members for sealing various places at which dribbling or leakage of the adhesive is likely to occur or as a result of which hardening or oxidation of the adhesive may occur. It will also be observed that the arrangement is such that the flexible member is not distorted by the weight of the material in the container except'to the extent that it is pressed into closing position against the rigid wall surrounding the orifice, even though a quantity, limited in this case to the volume of the channel I5, is normally in close proximity to the discharge orifice. It will further be observed that the perforations weaken the intermediate section of the member 6 so that the boss 9 is held by the liquid in the container in tighter sealing engagement with the interior wall of the funnel I3 while at the same time this sealing engagement may be more readily and easily broken by inward pressure executed on the tip 9.
While but a single embodiment of the invention has been described, other embodiments Within the scope of the appended claims will be obvious to those skilled in the art from a consideration of the form shown.
Having thus described my invention, what I claim is:

A liquid dispenser including, in combination, a container having an opening, and a closure for the opening, said closure comprising a rigid integral member vattached to the container and having an orifice, and al deformable integral member having -a portion extending between the rigid member and container to form a liquidtightseal for the joint therebetween, and also having another portion with a tip projecting through said orice in liquid-tight engagement therewith to seal the orifice as the sole result of the elasticity of the deformable member after the application of external pressure to the tip to open the orifice.
2. A liquid dispenser includingl in combination, a container having an opening, and a closure for the opening, said closure comprising a rigid integral'member having a rim attached to the container and also having a funnel projecting outwardly of the rim to an orifice, and an integral member of rubber having a peripheral portion clamped between the container and rigid member to form aliquid-tight seal for the joint therebetween, and also having a boss with a tip extending through and outwardly of the orifice in liquid-tight engagement with the interior of the funnel to seal the orifice as the sole result of the elasticity vof the rubber after the application of external pressure to the tip to open the orifice.
