SPREADING NOZZLE FOR ADHESIVE CONTAINERS Filed May 31, 1935 Patented Sept. 10, 1935 PATENT OFFICE SPREADING NOZZLE FOR ADHESIVE 7,: CONTAINERS William s. Stafford, New York, N. Y., assignor to S. S. Stafford, Inc., New York, N. Y., a corporation of New York Application May 31, 1935, Serial No. 24,184

4 Claims.

The present invention relates to improvements in the well-known type of flexible distributing nozzles for containers of fluid such as mucilage, such nozzles being formed with a normally closed slit which seals the closure against the entry of air and opens under flexing pressure to permit the fluid to exude when applied with slight pressure to the surface upon which the fluid is to be spread.

There are various forms of this type of distributing closure nozzles in use, but they are all subject to certain disadvantages when applied to packages of mucilage. Some of the mucilage left upon the exterior of the nozzle after each use, quickly hardens and seals the discharge slit and makes it diflicult to further operate until after the hardened discharge has been removed. Furthermore, some forms of this type of closure nozzle present too great a drag upon the surface operated upon.

To obviate these objections I have devised an improved flexible closure nozzle of the type referred to in which I provide a liquid spreading surface formed with longitudinal grooves which gradually deepen toward the tip of the nozzle and are traversed adjacent to the tip by the fluid releasing slit which extends through the wall transversely of the grooves. With this improved form of closure nozzle the mucilage is released by slight flexing pressure upon the grooved tip and is.

spread evenly upon the surface to which it is applied by the yielding ribs defining the grooves, causing the mucilage to be equally spread and leaving a minimum in the grooves at the completion of the spreading operation. The improved form of spreading nozzle is self-cleaning to a large extent, and the presentation of the grooved and ribbed portion of the spreading surface reduces the drag of the nozzle upon the surface being treated.

In order that the invention may be fully understood it will first be described with reference to the accompanying drawing and the novelty afterwards pointed out in the annexed claims.

Figure 1 is a front perspective view of the improved spreading nozzle or closure cap.

Figure 2 is a front elevation of the same.

Figure 3 is a longitudinal sectional view of the same.

Figure 4 is' a similar view showing the device in action.

The improved closure nozzle comprises a hollow molded cap of soft rubber having a base collar 5 designed to fit the externally flanged mouth 2 of a glass bottle 3 in which liquid mucilage is commonly sold. The walls of the cap or nozzle project from the base flange l in any preferred shape, such as the modified hollow cone shown, having the tip 4 which is the terminal of a substantially flat spreading face-5 which is presented I practically in line with one side of the bottle 3. The side walls 6 are substantially flat, though concaved slightly toward the base flange I, and the rear wall I is curved to meet the flat spreading surface 5 at the tip 4. The rear curved wall 10 l is preferably slightly thicker and stiffer than the other walls to retain the normal shape of the cap.

The flat distributing face 5 is formed in its outer portion with a series of longitudinal grooves 16 8 defined by the flexible longitudinal ribs 9. The grooves 8 are slightly tapered in depth, they being shallowest at their inner or base ends and deepest at the tip 4 or intersection of the distributing face 5 with the rear curved wall 1. 20

I0 is a normally closed liquid releasing slit cut through the front wall transversely of the distributing surface 5 adjacent to the outer tip end and extending transversely of and intersecting the grooves 8 and ribs 9. The elasticity of the 26 rubber retains the lips of slit l0 close together to prevent the escape of mucilage or the entrance of air to the bottle.

In using the container of mucilage provided with the improved distributing cap or nozzle the 30 grooved distributing face is presented toward the surface to which the mucilage is to be applied and with slight flexing pressure is drawn over the surface with the result that mucilage will be exuded through the opened outlet slit l0 and be 35 evenly spread by the grooved and ribbed distributing surface. With care the amount of mucilage applied can be nicely regulated by the amount of pressure applied. In applying the band of mucilage to a surface the grooved face causes prac- 40 tically all of the exuded mucilage to be deposited and evenly spread, the grooved distributing face being left with only a minimum of mucilage to dry upon it. When it is next desired to use the device a slight pressure upon the opposite flat- 45 tened side walls 6 with the thumb and finger readily spreads the lips of the slit Ill and breaks loose any slight dried film of mucilage left on the grooved spreading face from the preceding use.

The improved closure nozzle is practically self- 50 cleaning and is more delicate in operation and presents a minimum of drag upon the surface to which the mucilage is applied, while, at the same time, there is a more uniform distribution of the mucilage. Another advantage of the improved 55 form of spreading nozzle is the economy of manufacture, both as to cost of molds and the price of the finished article.

I claim:-

1. A self-cleaning elastic closure nozzle for liqquid receptacles having a longitudinally grooved spreading surface and a normally closed liquid releasing slit in said spreading surface extending transversely of said grooves.

2. A self-cleaning flexible elastic closure nozzle for liquid receptacles having a longitudinally grooved and ribbed spreading surface and a normally closed liquid releasing slit in said spreading surface extending transversely of said grooves and ribs.

3. A self-cleaning flexible closure for liquid receptacles comprising an elastic hollow cap adapted to fit the mouth of a container and having a spreading surface formed with longitudinal grooves adjacent its outer tip, and a normally closed liquid releasing slit in the wall of said surface transversely oi said grooves adjacent to said outer tip.

4. A self-cleaning flexible closure for liquid receptacles comprising an elastic hollow cap adapted to fit the mouth of a closure and having a spreading surface formed with longitudinal tapered grooves increasing in depth toward the outer tip of the cap, and a normally closed liquid releasing slit in the wall of said cap transversely of said grooves adjacent to the outer tip.
