BOTTLE CLOSURE Filed April 18, 1962 INVENTOR.
pm? s 9M? 4 TTORIVEYS.
Unite This invention relates to a bottle closure and, in particular, to a bottle closure incorporating a locking mechanism for securing the cap to the bottle whereby the same cannot be removed without the proper manipulation of the bottle. As many deaths and injuries each year, especially to children, are caused by easy access to a bottle containing poison or other harmful substance, this invention is directed to providing a bottle and cap locking means which renders it diflicult for a child under the age of six years to remove the cap, and yet fairly'simple for an adult or older child to overcome the locking mechanism and have access to the contents.
The prior art shows a variety of containers and mechanisms for securing the cap to the container proper. One
States atent ice Patented Aug. 27, 1963 2 as plastic, which contain suflicient structural strength to support a fluid or such, and yet are flexible enough to allow the sides of the container to be manually flexed inwardly. The neck 1'5 can be of the relative size shown in FIG. 1, joining the upwardly extending shoulder portion 11, or the neck can be connected directly to the container itself.' The top annular surface 11a of the such reference is the U.S. Patent No. 2,980,275, inventor R. A. I. Lundgren, issued April 18, 1961. The locking mechanism for jars as disclosed in that patent, necessitates the use of a separate, flexible ring which fits over the top of a jar and has a series of spurs which engage indentations in the cap. The mechanism disclosed by Lundgren has certain disadvantages which are overcome by the present invention. First, the Lundgren mechanism requires the use of a separate component which must be provided for each jar and cap and which must be of such size and construction as to fit tightly over the neck of the particular jar so as to engage a notch on the jar. Second, Lundgrens mechanism is substantially easier to disengage than that disclosed *by applicant, and does not provide locking means which grips'the cap as positively as does the mechanism disclosed by applicant.
Therefore, it is an object of this invention to provide locking means associated with the bottle for securing an ordinary screw-on bottle cap which allows the cap to :be removed only when the bottle'is manipulated correctl-y.
It is another object of this invention to provide a locking mechanism for a cap and bottle closure in which the parts may be quickly and easily operated to disengage the locking means by a person or older child who understands the mechanism involved.
It is a further object of this invention to provide a bottle locking mechanism which may be fabricated from commonly available materials according to a simple construction. These and other advantages will become more apparent from the description herein and the drawing attached hereto, in which:
FIG. 1 is a side elevational view showing one form of the top of the container of this invention;
FIG. 2 is a top: view of the container shown in FIG. 1;
FIG. 3 is a sectional View taken along the lines and arrows III-III of FIG. 2;
FIG.. 4 is a side elevational view of the cap of one form of this invention;
FIG. 5 is a side elevational view showing the capassembled on the bottle;
FIG. 6 is a perspective 'view showing the cap and the top of the container; and 5 FIG. 7 is an enlarged side elevational view partly in section, showing one form of the locking mechanism of this invention and the method of releasing the same.
One specific form or my invention is illustrated in FIG. 51, wherein the flexible wall container 10 is shown with an upwardly extending shoulder portion 11 and a neck 15 connected thereto. The container may be tabricated from any of a variety of flexible materials, such shoulder portion 11, I35 shown also in FIG. 2, is relatively flat and is provided with one or more saw-tooth protrusions or spurs 12 which extend outwardly from the flat surface 11a. The two protrusions 12 shown in FIGS. 1 to 3, are preferably positioned diametrically opposite to each other across the neck 15 of the cont-ainer and these protrusions'have a shape substantially that of a wedge. As shown, the spur 12 preferably is straight on one side 12a and tapered on the other 121). In addition, the spur 12 extends outwardly away from the neck of the container, as shown in FIG. 3, with the top edge of the spur substantially horizontal. It should be understood that any number of spurs or teeth 12 may be arnanged in the position desired around the top surface 11a of the shoulder 11. The neck 15 is equipped with a spiral thread 16 which complements the thread positioned in the interior surface of cap 20.
Cap 20, as shown in FIGS. 4 and 6, has a knurled surface 21 which extends around the cap 20 so as to provide a gripping surface. The bottom annular surface of the cap 20 is provided with a series of indentations 22 which are in the form of saw-tooth grooves. Each indentation 22, substantially similar in shape to the protrusion 12, has a straight side 2211 and a tapered side 22b whereby the protrusion 12 engages the straight side of the serration 22, shown in FIG. 5, and prevents the cap from rotating in the loosening direction, i.e., the direction of the arrow of FIG. 7. The internal surface of cap 20 is provided with a spiral thread 25 which is of such size as to engage thread 16 of neck 15. As the protrusions 12 are composed of the 53.1116 flexible material as the container 10 and are angularly disposed similar to the indentations, as described, the cap and indentations slip over the top of the protrusions as the cap is tightened in the direction of the arrow in FIG. 5, thus allowing the cap to be threaded into contact with the flat surface 11a of the shoulder 11.
As shown in FIGS. 5 to 7, the cap 21 is securely fastened to the neck 15 of the container 10 by rotating the cap in the direction of the arrow in FIG. 5. As the cap, and more specifically thread 25, progresses down the thread 16 of the neck, the indentations 22 around the annular bottom surface of the cap pass over the tapered spurs 12 until the bottom surface of the cap is firmly against the shoulder 11, at which time the spur 12 fits within one indentation as shown in FIG. 5. When the spur 12 is firmly within the serration, the cap is prevented from rotating in the loosening direction.
To allow the cap to be removed from the container, or rotated in the direction of the arrow of FIG. 7, the container body 10 is flexed inwardly as shown in FIG. 7. When the sides of the container 10 are flexed inwardly at a position adjacent the shoulder 11 and adjacent the protrusions 12, the top surface of the flexible shoulder I 9 a tainer sides inwardly so as to dislodge the spur from the indentation of the cap, and the second hand is used to rotate the cap in the loosening direction while the spur is displaced away from the indentation. Further, it should be understood that as the Container and cap may be composed of materials having varying degrees of flexibility, the degree of strength required to flex the container 1nwardly will vary according to the material used, and, correspondingly, a stifler material will require strength not found normally in younger children. As the opening of this container requires the dexterous use of both hands, the container hardly could be opened by chance by children at play.
In this single embodiment of my invention, the shoulder portion 11 is fitted with only two spurs. If desired, a single spur tor a plurality of spurs may be provided arranged around the shoulder at convenient positions. Similarly, a different locking mechanism may be used rnplace of the tapered protrusions and indentations shown without departing from the spirit of this invention.
Further, this invention is not [to be understood as restricted in other ways to the details set forth, since these may be modified to provide for a container with various shapes, sizes and uses to satisfy widely divergent needs in daily living. Such changes and modifications will be well within the scope of the appended claims without departing from the spirit and scope of this invention.
