5 Claims.

My invention relates to containers such as bottles and the like, and particularly to containers designed for holding pharmaceutical or chemical preparations in liquid form.

It is well known that in pouring a liquid from a bottle a drop of the liquid always adheres to the neck when the bottle is tilted back to its vertical position, and, since the drop hangs from the outer edge of the neck, when the bottle is righted the drop usually runs down the outside of the bottle. Furthermore, when the bottle is placed upright, the liquid remaining on the edge of the neck usually spreads over the top of the neck of the bottle, forming a film of liquid thereon. This characteristic of bottles or containers is extremely objectionable when the liquid is of a corrosive or sticky nature or tends to harden are dangerous to handle if the liquid is corrosive and present an extremely unsightly appearance when streaked with colored or sticky liquid. When caps are applied to receptacles of this type the film of liquid on the top of the neck tends to corrode or rust the cap and threads, contaminating the liquid and rendering it extremely difficult to remove th cap after the bottle has stood for some time.

Containers for paint, varnish, lacquers and so forth, which tend to harden on drying, are also subject to this objection, and for this reason paint cans are not ordinarily provided with threaded necks, although threaded closures provide considerable advantages over closure of other types for use on containers having liquids therein which tend to evaporate.

Attempts have been made to overcome the disadvantages inherent in bottles formed with rounded upper edges at the top of the neck by forming an outwardly turned tapering-lip which is considered to reduce the amount of liquid adhering to the edge of the bottle. However, even with such construction the outlet opening in the neck of the bottle is circular so that the liquid in passing over the edge of the neck flows over a relatively large portion of the circumference thereof, wetting the same and causing the liquid to flow laterally over the top of the neck when the bottle is righted so that corrosion and sticking of the cap is not materially reduced.

Furthermore, 'it is common practice to provide containers with internally threaded necks formed with an externally located pouring spout,

the container being closed by an externally threaded plug or closure fitting within the neck so that the pouring spout is always exposed. How-- ever, this construction is not adapted for use on bottles or glassware wherein the pouring spout is liable to be injured during shipment or handling of the bottle.

. In accordance with my invention, the fore- 5 going objections and difiiculties presented by the use of bottles and containers of the prior art are overcome and a container provided which is formed with an externally threaded neck adapted to'receive and engage an internally threaded cap 10 formed with complementary threads, the neck being provided with a pouring spout designed to be covered by the closure member and formed to confinethe liquid being discharged from the container to a limited area of the neck of the 16 container. The provision of a pouring spout serves to prevent the flow of liquid down the outside of the bottle or laterally about the top of the neck when the bottle is righted.

In the present invention the container is pro- 20 vided with a threaded neck having a pouring spout formed thereon. However, in the present instance the neck is threaded substantially to the top thereof and the pouring spout may be located in whole, or' in part, within the threaded portion 25 of the neck.

One of the objects of my invention is to prevent the fiow of liquid down the exterior of the neck or laterally over the top of the neck of a container. 30

Another object of my invention is to prevent the corrosion and sticking of threaded caps to the necks of containers.

A further object is to provide a container having an externally threaded neck formed with a 35 pouring spout thereon.

Another object is to provide a container having a pouring spout adapted to be covered by the closure for the receptacle.

A further object of my invention is to provide 40 a bottle adapted to contain pharmaceutical or chemical preparations in liquid form which is free from the difiiculties and disadvantages inherent in bottles formed with circular outlet openings. as

Another object of my invention is to provide a container having a neck threaded substantially to the top thereof and having a pouring spout formed in the neck.

These and other objects and features of my in- 50 vention will appear from the following description of preferred forms thereof, in which Fig. 1 is a plan view of a preferred: structure as applied to a bottle;

Fig. 2 is a vertical sectional view of a bottle drical throughout with a cap thereon taken on the line 2-2 of Fig. 1.

Fig. 3 is a perspective of a bottle having the neck thereof formed as shown in Figs. 1 and 2, with the cap removed.

Figs. 4 and 5 respectively, show a side and a perspective of an alternative form of structure embodying my invention.

In the form of the 1, 2, and 3, of the drawing the container is in the form of a bottle 2 having a neck 6 provided with a. thread 6. A shoulder 8 may be formed on the: neck of the bottle below the thread to limit the downward movement of the cap if desired. The thread 6 at the point In is interrupted for a suflicient distance to permit the formation of a pouring spout E2. The pouring spout is formed by a contraction of the material from which the neck is formed at the points it on either side of the spout l2 and within the space it in the interrupted portion of the thread e. The interior of the neck of the container is substantially cylinthe portion id thereof and is formed with depressed portions 56 on either side of the pouring spout it. The pouring spout thus constitutes an angularly formed lateral projection on the neck of the container which serves to confine the liquid as it is poured therefrom.

I prefer to construct the pouring spout with inwardly and sloping lower sides so asto cause liquid to drain back into the bottle from the pouring spout when the bottle is righted after pouring liquid therefrom.

The top of the neck of the container is preferably flat, so that the entire top of the neck lies within a single plane. The neck thus provides a flat surface against which a packing member may bear to seal the container against leakage during handling and shipping thereof.

A cap i formed with a continuous thread it is adapted to engage the thread 6 on the neck of the container. Packing member 22 is carried by the cap in the top thereof so that upon screwing the cap down on to the neck of the container the packing member will engage the top of the neck to seal the container against leakage.

By this arrangement, the container is formed with a pouring spout within the threaded portion of the neck thereof and at the same time the usual threaded cap employed for closing, such containers may be used. The outer extremity of the pouring spout i2 is located in alignment with, or within the inner diameter of the thread t, as determined by the vertical portion of the neck. of I the bottle. For this reason the pouring spout does not interfere in any way with the application or, the removal of the cap from the con tainer. When the cap is applied the po spout is wholly covered by the cap so that injury thereto in handling the container is avoided.

In the alternative form oi the invention, illustrated in Figs. 4 and 5, the thread 6 is formed so that it begins at one side of the pouring side it and terminates at the opposite side thereof. The pouring spout is thus located between the ends of the thread and does not interfere in any way with the application of a cap thereto. In this form of the invention the outer extremity of the pouring spout i2 may be positioned 'so that it extends into the thread on the cap forming in efiect a. portion of the thread 5. This construction has the added advantage that the pouring spout l2 may extend beyond the vertical portion of the neck d and into alignment with the outer However, the edge may invention illustrated in Figs.

diameter of the thread 6. For this reason the pouring spout it may be formed somewhat larger than in the construction illustrated in Figs. 1, 2, and 3, without interfering with the application of the cap to the neck of the bottle.

In the drawing I have illustrated bottles in which the edge of the top of the neck is fiat. of course be rounded or bevelled if desired, but in any case I prefer that the top of the neck should be entirely in a single plane so as to provide a suitable surface against which the packing member may engage to seal the container against leakage.

While I have illustrated and described two alternative forms of my invention, it will be apparent that the invention is not limited to these. particular structures or to the use thereof on bottles or glass receptacles, but may be applied to other containers whether formed of metal, resinous compositions or other material. It should therefore be understood that I do not wish to confine my invention to the preferred forms thereof herein illustrated and described except as defined by the claims.
