DETACHABLE SPOUT FOR CONTAINERS Filed Jan. 3, 1938 2 Sheets-Sheet 2 6 v JOSEPH B ENGLERT INVENTOR Pl 5 6 ATTORNEY Patented June 4, 1940 UNITED STATES PATENT OFFICE ll Claim.
This invention relates to improvements in detachable spouts for containers and while intended for use generally on any form of container to which it may be advantageously applied, it is particularly applicable as an improvement in spouts for milk bottles in which connection it will be illustrated in the drawing and hereinafter described.
Objects of the invention are to provide a spout of simple, durable construction, which may be manufactured at a low cost, which will fit bottles or other containers of different shapes and sizes; which may be quickly and conveniently positicned on a container or removed therefrom; which may be easily cleaned or sterilized and which will be very eflicient in use.
Other objects are to provide a closure member for bottles and other containers which will be composed of one piece of elastic material arranged to fitsnugly about the mouth of a bottle or other container, and which is provided with a self-closing spout arranged to permit the pouring of liquid from the container without spilling or otherwise wasting the liquid.
An additional object is to provide a spout composed of one piece of elastic rubber, with a lug forming a handle portion and arranged to hold a bottle cap during the pouring operation.
The above and additional objects are attained by the novel construction hereinafter described with reference to the accompanying drawings wherein there is shown a preferred form of the invention, it being understood that the invention may be adapted in various ways to various forms of containers and that changes and modifications may be made which come within the scope of the appended claim. e
In the drawings:
Figure 1 is a side elevational view showing the upper portion of. a milk bottle with a closure member constructed in accordance with this invention operatively positioned thereon,
Figure 2 is a central, vertical view of same taken as indicated by the lines 2-2 of Figure 3,
Figure 3 is a top plan view of same,
Figure 4 is a side elevational view of the upper portion of a container showing an adaptation of the invention in which the top wall is omitted.
Figure 5 is a top plan view of same,
Figure 6 is a vertical, sectional view taken as indicated by the lines 6-6 of Figure 5.
Proceeding now to a detailed description of the invention with reference to the particular adaptation thereof. illustrated in the drawing, the numeral 6 is used generally to denote a bottle or other container. The bottle 6 is provided around the top thereof with the usual flange 1 which in the particular bottle shown in the drawings is of rounded cross sectional shape. The mouth of the bottle 6 is enlarged at the outer 5 end thereof to provide a shoulder 8 which supports the closure cap ordinarily used in covering the mouth of the bottle.
A cap constructed in accordance with this invention is molded or otherwise formed of one 10 piece of rubber and is provided with a base portion 9 which is in the form of a band adapted to fit around the flange 1. The band 9 is preferably bulged outwardly to conform in shape to the flange I and is normally smaller than the flange 15 I on which it is to be positioned. A spout it projects upwardly from one side of the flange i.
The spout l0 conforms in shape to a portion of a wall of a hollow cylinder and is arranged with the upper edge thereof inclined downwardly 20 toward the central portion of the bottle.
The numeral ll denotes a top wall which is a continuation of the base 9. A portion of the top wall H extends straight across the mouth of. the bottle and is continued upwardly to form the in- 25 clined flap [2. The flap I2 is formed to be normally positioned against the upper end of the spout I0, whereby the elasticity of the material of which the cap is composed will normally hold the flap [2 in a closed position. The flat top portion II is provided with an aperture l3.
The numeral I5 denotes a flap which is composed of elastic rubber and is secured to the top Wall II at a point spaced from the aperture [3 with the free end of the flap covering the aperture I3 whereby air will be admitted to a bottle to cause a smooth flow of liquid from the spout Ill. The flap l5 covers the aperture when the container is in an upright position to exclude dirt, dust or other objectionable substances from entering the said aperture.
In the modification of the invention shown in Figures 4 and 5 and 6, the top wall I l and the lid I2 are omitted thereby forming a detachable 45 spout which may be positioned on a milk bottle or similar container without interfering with the use of the ordinary closure disk.
The ring 9 is provided on the outer side thereof at a point directly opposite thespout H! with an 5 integrally formed lug it which projects radially therefrom- The lug i6 is provided with a vertical slot ll for receiving and holding a disk ordinarily used as. a closure member. The portion l6a of. the lug I6 projects upwardly to form a handle 55 which may be used in placing the spout on a bottle and in removing the same therefrom.
The ring 9 is preferably provided with an outwardly projecting annular bead I8 on the lower edge thereof which is formed thereon to strengthen the lower edge thereof and to provide means for more securely holding the ring in an operative position on a container.
In use, the base portion 9 is stretched over the flange 1 of a bottle or other container with the spout II in the position shown in the drawings. As the structure herein disclosed is composed entirely of elastic rubber, it will be securely held in position on the container and will provide efiicient means through which liquid may be poured from the bottle without spilling. The flap l2 being formed of elastic rubber will be forced open by the weight of the liquid to be poured. The flap I5 is in a position where it can in the form of a flap.
readily be manipulated to admit air to the bottle during the pouring operation. If desired, pressure may be applied to the lid l l or to the lower I thereof, and an integrally formed top wall on said base, said top wall extending over said spout JOSEPH B. ENGLERT.
