Sheafier Pen Company, Fort Madison, Iowa, a corporation of Delaware Application July 3, 1941,.Serial No. 490,907

2 Claims.

This invention relates to a pour-out closure and has special reference to a spout for directing the flow of fluid from a container, the spout extending from a main body portion which engages and seals the contents of the container when not in use.

More particularly, this invention relates to a pour-out closure for containers comprising a main body portion having an annular depending skirt with connecting means for detachable engagement with the neck of th bottle, the main body portion having an oblique spoutan'd an open-ended passage extending axially of the spout for discharging liquid from the container. A shoulder extends radially inwardly from the skirt for seating on the top and adjacent the outer edge of the neck of the container and an annulus is spaced from the shoulder for seating on the top and adjacent the inner, edge of the neck of the container, the shoulder and annulus providing a double seal for the container.

The present invention will hereinafter be described in the association of a pour-out closure with a bottle for containing writing fluids wherein it may be desirable to fill small individual bottles of writing fluid from a supply bottle. It is essential, of course", to seal hermetically the larger supply bottle when stored and not in use, while it is desirable to direct readily and conveniently the flow of fluid from the bottle when supplying the individual bottles.

' The spout is provided with an open-ended passage which is divided into pouring and vent openings. The vent opening permits air to enter the container for replacing the fluid poured from the bottle. The provision of the air vent avoids the pulsating efiect ordinarily accompanying a, single opening which is common to both the pouring and vent passages. The spout is preferably provided with a closure for sealing the divided passage forming the pouring and vent openings and the mouth of the neck of the bottle is provided with a double seal on theinside and the outside of the upper edge of theneck.

In the construction shown annulus depends from the top of the main body portion and occupies a spaced relation with the shoulder formed radially inwardly from the skirt which permits of a substantially uniform cross section throughout the entire closure. The snacin".

oflthe annulus from the shoulder permits stretching of the gasket disposed on the top of the neck ofe bottle. across the thickness of the material i'oti ng the neck and provides pressure on the on w inthe drawing, the

and inner edge portions thereof. Since the least there is a tendency for the annulus and the shoulder to be f rced in opposite directions, owing to the slight cu atures at the edges of the upper end of the neck.

One of the objects of this invention is to provide a pour-out closure of the character indicated above wherein a double seal is efiected'at the upper edges of the neck of the bottle or other container.

Another object of this invention is to provide a pour-out closure for bottles or other containers of the type hereinabove mentioned wherein the closure may be formed with a' substantially uniform cross section to obviate any so-called sinks in the material.

Itis also an object of this invention to provide a pour-out closure of the type indicated above wherein the gasket between the closure and the neck of the. bottle is stretched between the outer and inner edges thereof.

It is a further object of this invention to prois comparatively inexpensive to manufacture. is

efl'lcient and simple in operation and is durable.

Other objects and advantages of this invention will hereinafter be more particularly pointed out and for a more complete understanding of the characteristic features of this invention, reference may now be had to the following description when taken together with the accompanying drawing. in which latter:

When the closure is disposed on the neck of the bottle in a sealing relafion, the annulus 22 and the shoulder 2| are forced against the gasket 23 and onto ,the top of the neck ll of the bottle. The sealing/gasket is compressed between the edges of the bottle and the annulus and the shoulder at spaced areas about its periphery and by reason of the provision of a slight radius on the inner and outer edges of the top of the neck of the bottle there is a tendency for the annulus and the shoulder to spread apart and elect a stretching of the gasket over the top edge of the can themmmkforflhe ad is;
