Description

May 21, 1957 H. STEWART v CONTAINER AND SPOUT THEREFOR Filed June 3, 1955 IN V EN TOR. flail 5Z'ez1/czr This invention relates to a spout for a container and to the container including the spout.
One of the features of this invention is to provide a spent for a container adapted to be attached to a wall thereof and extend outwardlythrough anopening therein comprising a spoutbase of plastic" material adapted to extend through said opening, an outerplastic' flange integral with said base and adaptedto bear against an outer surface portion of' said wall adjacent to said: opening and make sealing contact therewith; an'dan inner plastic flange integral with said base and adapted tobear against aninner surface portion of said wall adjacent to said opening and make sealing? contact therewith, the inner and outer flanges each adapted to cover an area greater than that of said opening so as to embrace the wall portion defining the opening, the spout base being tapered inwardly from said inner flange to s'aid inner end to aidin inserting said base into said opening, the extreme inner and of the spout having a diameter less than that of said opening.
Another feature is to provide an improved container comprising a wall having an opening defined by an inwardly turned substantially cylindrical wall portion, and a spout positioned in said opening including a spout base of plastic material extending through said opening, an outer plastic flange integral with said base and bearing against an outer surface of the wall adjacent to said inwardly turned wall portion and in sealing contact therewith, and an inner plastic flange integral with said base and bearing against the inner edge of said inwardly turned wall portion, the inner flange being of small width to provide a step construction and said inwardly turned wall portion being located between said flanges, the spout base being tapered inwardly from said inner flange to said inner end to aid in inserting said base into said opening, the extreme inner end of the spout having a diameter less than that of said opening, the portion of the spout between said flanges being relativelythick in order to aid in preventing accidental inward distortion thereof, the outer flange having an extreme outer edge tapered rearwardly toward the inner end of the spout.
A further feature is to provide an improved container comprising a wall having an opening defined by an inwardly turned substantially cylindrical wall portion, and a spout positioned in said opening including a spout base of plastic material extending through said opening, an outer plastic flange integral with said base and bearing against an outer surface of the wall adjacent to said inwardly turned wall portion and in sealing contact therewith, and an inner plastic flange integral with said base and bearing against the inner edge of said inwardly turned wall portion, the inner flange heing. of small width to pro vide a step constructionand said inwardly turned wall portion being located between said flanges, the spout base being tapered inwardly from said inner flange to said inner end to aid in inserting said base int'os'aid opening, the extreme inner end of the spout having a diameter i States Patent O 2,792,976 Patented May 21, 1957 2. lessthan that of said opening, the portion of the spout between said flanges being relatively thick in order to aid in preventing accidental inward distortion thereof, the outer flange having an extreme outer edge tapered rearwardly toward the inner end of the spout.
Other features and advantages of the invention will be apparent from the following description of the invention, particularly as related to the accompanying drawings. Of the drawings:
Figure 1 is a perspective view of a container and spout embodying the invention.
Figure 2 is a longitudinal section through the spout and the adjacent portion of the container.
Figure 3 is a fragmentary perspective view of an alternate embodiment of the invention.
Figure 4 is aview similar to Figure 3 but with the tip of the spout removed.
Figure 5 is a view similar to Figures 3 and 4 but with a nozzle cap in place on the end of the spout.
Figure 6 is a fragmentary perspective view of the invention with the flexible plastic tube in place in the manner illustrated in Figure 1 and the tube arranged in closed position.
Thecontainer 10 illustrated in the drawings includes an end walll'l. This end wall is provided with an opening adjacent to an edge thereof defined by an inwardly directed substantially cylindrical flange 11a. This flange 11a is of relatively short height and is uniform in height, and define a substantially circular opening 11b.
Normally positioned within the opening 111: is a spout 12"of reluctantly deformable relatively rigid plastic material; This plastic spout includes a base 13 extending through the openingll'b. The base has an outer plastic flange 14 integral therewith and bearing against the outer surface of the wall 11 adjacent to the inwardly turned flange 11a. The base 13 is also provided with an inner plastic flange 15 integral with the base and bearing against the inner edge of the wall flange 11a. This inner flange 15 is of small width in order to provide. a step construction. The container wall portion 11a is normally located between the spout flanges 14 and 15. when the spout is in position in the opening 11b.
The extreme inner end of the spout base. 13 has its outer surface 13a tapered inwardly from the inner flange 15 to the inner end 16 of the spout. This inner end 16 has an outer diameter that is less than the diameter of the opening defined by the wall flange 11a. The spout has the portion of the base 13 between. the flanges 14 and 15 relatively thick in order to prevent accidental inward distortion of the plastic base at this point to aid in preventing accidental breaking of the seal between the spout base and the container wall.
The outer spout flange 14 is of relatively large diameter compared to the remainder of the spout and to the diameter of the opening 11b in the container wall 11. The outer surface 14a of this flange 14 is curved outwardly and inwardly toward the container wall 11 in order to mesh smoothly therewith. In its undistorted position before the spout has been fixed in place within the opening 1112, this outer flange 14 is generally inwardly concave. Thus, positioning of the spout within the opening 11b in the manner illustrated in Figure 2 results in the flange 14a being pressed firmly against outer surface of the container wall 11.
As has been pointed out, the surface 13a of the base between the end 16 and the inner flange 15 is tapered in order to aid in inserting the base into the container opening 11b. To further aid this insertion, the bottom 15a of the inner flange 15 is similarly tapered.
When the container 11 and the spout 12 are sealed, theextre'me end 12a is closed so as toprovide a sealed tip. When it is desired to expel the contents of the other greases container or a portion thereof, this tip 12a may be removed as by cutting the extreme end of the spout with a knife 17 in the manner illustrated in Figure 3.
In the preferred construction, a flexible plastic tube 18 is provided for use with the spout 12. Then if desired the tube 18 may have one end 13a slipped over the outer end of the spout 12 so that the end 18a is frictionally held on the spout. With this construction, the tube 18 operates as an extension of the spout 12 to guide the contents of the container to the desired destination. The tube 18 can, of course, be used only if desired.
One method of sealing the spout if only a portion of the contents of the container are expelled so that there is a portion of the contents remaining is illustrated in Figure 6. By this method, the tube 18 is bent back upon itself and the contacting portions squeezed together as by paper clip 19.
Another method of sealing the end of the spout 12 is illustrated in Figures 3, 4, and 5. In this embodiment, a molded plastic cap is attached to the outer spout flange 14 as by narrow neck 20a of plastic material. When it is desired to use this cap 20, the neck 20a is served as by using the knife 17 and the cap pressed down on the end of the spout 12 to make frictional sealing contact therewith in the manner illustrated in Figure 5.
The spout 12 may be made of any inert plastic material that is not attacked by the contents of the container 10. In one embodiment, both the spout 12 and the tube 18 were constructed of polyethylene. The polyethylene of the spout 12 is relatively rigid yet deformable under pressure. In contrast, the polyethylene of the tube 18 is flexible so that the tube can be easily bent in the manner illustrated in Figure 6. It is, of course, obvious to those skilled in the art that any of a large number of plastic materials or resinous materials may be used in place of the polyethylene.
In inserting the spout 12 into the opening 11b, the base 13 of the spout is heated by any means desired to a temperature above the softening point of the plastic material. At this temperature, the base 13 is deformable so that the base can be then inserted through the outer end of the opening 11b. The spout is thereupon pressed inwardly until the outer spout flange 14 bears firmly against the outer surface of the container wall 11 and the inner flange 15 springs in behind the wall flange 11a to the position illustrated in Figure 2.
In the illustrated construction, the flanges 14 and 15 are spaced apart so that the wall flange 11a is grasped firmly therebetween. Furthermore, the diameter of the portion of the base 13 of the spout between the spout flanges 14 and 15 is slightly larger than the diameter of the opening 11b before the spout has been placed within the opening 11b. These factors, plus the relatively large area of contact of the base 13 and spout flanges 14 and 15 with the wall 11, including the wall flange 11a, insure a tight leakproof seal between the spout and the container.
As pointed out above, it is preferred that the nozzle 12 and the tube 18 be made of a similar plastic material. Thus, the preferred plastic material is polyethylene with the nozzle 12 being relatively hard, self-supporting, and resistant to deformation, while the tube 18 is flexible. When both the nozzle and the tube are made of polyethylene, it is noted that the end 18a of the tube when telescoped over the tip of the nozzle '12 in the manner illustrated in Figure 2 results in a joint that is very strong. Thus, it takes a tremendous outward pull of the tube 18 in order to break the contact. This is a surprising result as the polyethylene has a relatively low coefiicient of friction on metal, wood, and similar surfaces.
