CHANCELLOQ E CKHOF F & SL/CK y A 7'7'ORNEVS A MEMBER OF THE F/RM United States Patent 3,130,848 BGTTLE CAP WITH INTERRUPTED THREADS Roy 1). Chancellor, 1266 Naglee St, San Jose, Calif. Filed June 11, 1963, Set. N0. 287,073 4 Claims. (Cl. 215-9) This invention relates to a bottle or jar having a safety closure and more particularly to .such a structure requiring, to open, manipulations which are difiicult for small children.
It is an object of this invention provide a bottle or jar having a safety closure, all parts of which may be made of relatively inexpensive plastic material, if desired.
It is a further object of this invention to provide a safety closure for a bottle, jar or other container whichis relatively easily manipulated by adults but .sufiiciently difiicult for a small child that medicines, corrosive substances and poisons may be placed therein with relative safety.
Other objects and advantages of this invention, if not specifically set forth, will become apparent during the course of the description which follows.
In the drawings:
FIGURE 1 is an exploded view, partially in section, of the jar and closure of this invention.
FIGURE 2 is a plan view of the portion of the closure assembly which is second from the bottom in FIGURE 1.
FIGURE 3 is a sectional view through line 3-3 of FIGURE 4.
FIGURE 4 is a sectional side of elevation of the assembled structure of this invention taken through the line 4-4 of FIGURE 3.
FIGURE 5 is a plan view of the jar shown at the bottom of FIGURE 1 with the top assembly removed.
FIGURE 6 is a view similar to FIGURE 3 but showing the effect of depressing the deformable top.
FIGURE 7 is a side elevation, partially in section and similar to FIGURE 4 showing the effect of depressing the deformable top. 1
FIGURE 8' is a perspective view on a somewhat reduced scale showing the manipulations required to open the container.
Generally, this invention comprises a bottle, jar or other container having a top consisting of parts which may be partially or entirely made of inexpensive .fiex-ible plastic materialsand which is so constructed that it is necessary to depress the center of the top with one finger in order to unlock the top and permit it to be unscrewed from the container.
Referring now to the drawings wherein like characters refer to like parts throughout, there is shown a container 10 which, as seen in FIGURE 1, has helical threads 12 which are interrupted at least once at 14 and preferably at two or more places. For sealing. purposes, the lowermost of the threads should be continuous as at 12a.
The main portion of the closure consists of a collar, generally 16, which is internally threaded at 18. These threads register with the exterior threads ;12 and 12a of the container. Integral horizontal ring 20 has depending therefrom the generally cylindrical member 22 which has integral therewith and at right angles thereto the closure disc 24. As seen in FIGURES 1, 4 and 7, the lowermost edge of the cylindrical member 22 terminates in a sealing lip 26 which tightly engages the internal walls 28 of the container 10.
The ring 20 has at least one and preferably several holes 30 therethrough and a rectangular recess 31 is formed in the main body of collar 16 directly beneath each hole 30. Each recess is formed by interrupting internal threads 18. If there is more than one, as shown in FIGURE 2, they should be spaced to coincide with the areas of the interruptions 14 in the threads 12. Inte- "ice gral with the exterior-most portion of the ring 20 and with the upstanding rim 32 of the collar 16 the circular shoulder 34 having an interruption 36 which serves as a notch for the receipt of the tongue 38 on the ring 40. The ring also has at least one and preferably two or more depending tongues '42 which are proportioned to register with the holes 30 in horizontal flange "20 and to fit between the facing shoulders which form the interruptions 14 of the threads 12 as well as in the recesses 3-1 formed by the interruptions in the threads 18. The ring 40 is split at 44 so as topermit expansion and contraction and has at least two opposed inwardly extending tongues 46'. These are curved at their lead edges and form segments of a circle whichengage with the downwardly depending boss 48 on the flexible top member 50. 'The circular lip 52 on the inner edgeof the rim 32 of the closure member 16 grips the periphery of the top '50 to secure it in place. Hence, the elements 50, 40, and 16, while shown in an exploded form in FIGURE 1, form a unitary closure member when assembled.
In use, the three parts 50, 40 and 16 of the closure are assembled as shown in FIGURE 4 with the tongues 42 extending into the holes 30 and the tongue 38 gripped in the notch 36 of the shoulder 34. The tongues 42, when the ring '40 is in its normally constricted or relaxed position (FIGURE 4,), tend to lie flush against the walls of the container 10. 'When the coveris in place upon the container 10 and the top properly oriented relative to the container, the tongues '42 will rest between the shoulders on either side of the interruptions 14 of the threads '12. Because the tongue 38 permits no relative rotation between ring 4t and the collar 16, the entire closure will thus be locked to the container 10*. When the flexible plastic forming the top -50 is depressed as shown in FIGURE 7, the ring 40 will be expanded and tongues 46 will be forced outwardly into the recesses 31. FIGURE 6 shows the direction of application of force when the center of the top 50 is depressed. The entire assembly comprising uni-ts 16, '40 and 50 is thus released by withdrawal of tongues 42 from the interruptions 14 and may be turned and removed from the container.
Because removal of the cover requires a simultaneous application of force at the center of the deformable top 50 and application of a turning moment to the cover while the container '10 is held against rotation, it will be appreciated that removal of the cover by small children is difficult and the container is thus especially suitable for use with medicines, poisons, corrosive materials, etc.
The structure shown has two sealing features, one resulting from tight contact between the underside of the ring 20 and the upper surface of the jar or container while further assurance against leakage is provided by the complete thread 1201 which seals tightly with one of the internal threads 18 of collar member '16.
In FIGURE 5, a modification permitting the cover to be re-applied to the container 10 without depressing the centermost portion of the top 50 is seen. That is, assuming that the top is to be applied by clockwise rotation of the cover assembly to the container 10' shown in FIG- URE 5, it will be appreciated that the sloping shoulders shown in this figure will permit the tongues 42 to ride up over them so as not to interfere with clockwise rotation of the cap relative to the container 10.
Obviously, many modifications and variations may be made without departing from the spirit and scope of this invention, and therefore only such limitations should be imposed as are indicated in the appended claims.
