This invention relates to a safety closure.

This invention relates to a safety closure screwed on to the neck of the container and provided with means whereby a child would be unable to effect removal therefrom, but a knowing adult could make the proper adjustment to permit removal.

It is an object of this invention to provide means to prevent accidental ingestion of toxic materials, whether medicidal or household by young children.

It is a further object of this invention to provide a safety closure in combination with a container so constructed as to prevent a child from effecting easy removal therefrom but permits a knowing adult to effect such removal.

Another object of this invention is to provide a safety closure and container combination that can be readily manufactured, inexpensively.

FIG. 11 is an opposing side sectional view showing the locking position of FIG. 9 in another locked position; and

FIG. 12 is an enlarged sectional view of the engaged closure threads and container threads showing an un locked position.

Heretofore it was generally required that a separate locking member be provided to ensure a safe and positive seal of a closure on a container. By this present invention there is now provided a closure and container combination wherein a positive locking member is integrally housed within the closure. After screw tightening the closure on the container in a usual manner, no further manipulation is required for positive locking of the closure on the container.

Referring now to FIGS. 1-8, there is shown the safety closure 10 screwed onto the neck portion 11 of container 12.

The neck 11 of container 12 has integrally formed thereon external threads 17, and at the base of the neck portion, actuating means 130, and on the neck portion below the end 17a of the external threads 17 is stop means 13b. Spaced opposed surfaces of actuating means 130 and stop means 13b and 13a] and 13b1, respectively.

The closure 10 comprises a horizontally disposed top wall 14, a vertically disposed cylindrical annular wall 15, internal side wall threads 16 (FIG. 4) for engaging external neck threads 17, and a transverse hole 25 in the annular wall. The closure 10 further comprises an outwardly protruding annular portion 24 on the outward surface of side wall 15, having central hole 25 therein and passing through the entire annular wall 15. On the surface that forms hole 25 is formed a radially extending slotted groove 23.

Pivoted locking means 18 is transversely disposed to closure annular wall and rotatably housed within the ing a groove slot 21a transversely disposed through said oblongated sides 21c. The dimensions of the oblongated raised portion are such that the smaller sides 21b of the oblong are sufficiently small to permit the oblongated raised portion 21 to slidably fit between adjacent thread portions of theneck thread 17, when the pivoted locking member is in a first pivoted position (see A of FIG. 8). The dimensions of the groove slot 21a are sufficient to blockingly engage a thread portion of the neck thread 17, when the pivoted locking member 18 is in a locking pivoted position (not shown).

Radially extending on the cylindrical body portion 19, are formed two diagonally disposed lock buttons 22 (typical). The lock buttons 22 are slidably movable within internal groove 23 of protruding portion 24 (FIG. 7).

The protruding annular portion 24 may be of flexible resilient plastic to permit the lock buttons 22 (typical) to snap-lock the pivoted locking means 18 into the closure wall 15. At the upward portion of annular portion 24 is formed a stop member 23a (position C of FIG. 8).

To pivot the pivoted locking member 18, wing 20 is arcuately moved to any desired position, the cylindrical body portion 19 being rotated within the hole 25 of closure wall 15 as the lock buttons slide within groove 23.

To screw closure 10 onto neck 11 of container 12, pivoted locking means 18 is firstly rotated to position A (FIG. 8). And the cap is then screwed down; the oblongated sides 21c of raised member 21 slidably engaging the sides of the neck threads 17. Prior to tightening down on the closure, the closure and pivoted locking means 18 are in a position as shown in FIG. 1 and FIG. 4. Further tightening of the closure causes wing portion 20 to contact actuating means 13a causing pivoted rotation of pivoted locking means 18 which in turn causes misalignment of oblongated raised portion 21 with the neck threads 17, as shown in FIG. 2, FIG. 5. Further continued screw tightening causes the rotation of wing portion 20 and oblongated raised portion 21 of pivoted locking means 18 to assume the position B as shown in FIG. 8. The closure is now in a safety locked position.

In the event a child would attempt to remove the closure 10 by returning the closure, the raised portion 21 blockingly contacts the end of neck threads 17 thereby preventing removal (see FIG. 6).

To remove the closure, pivoted locking means 18, specifically wing 20 thereof, is vertically aligned between opposed surfaces 13a1 and l3b1 of actuating means 13a and stop means 1312 respectively, as shown in FIG. 4. The oblongated member 21 is then slidably engageable between adjacent container neck threads.

To prevent alignment of oblongated member 21 between the neck threads, when the wing portion is turned 180 from said first position (A of FIG. 8), there is provided on protruding portion 24 a stop 23a. The stop 23a blockingly contacts wing 20 and thereby prevents further rotation of the pivoted locking means. As stated, blocking relationship is shown as position C in FIG. 8.

In FIGS. 9-l2, there is shown another embodiment of this invention, as described hereinafter.

Referring now to FIGS. 9-12, there is shown a closure 101 comprising a horizontally disposed top wall 102, a vertically disposed cylindrical annular wall 103 having a transverse hole 104 therethrough, said transverse hole having a radially extending groove 104a. Further said closure 101 is formed with internal threads 105 on the inward surface of annular wall 103. In combination with the closure 101, is a container 110 (partially shown) being integrally formed with a neck portion 111, said neck portion being integrally formed with external threads 112 for engaging said closure threads 10S. Near the lower portion of the neck, on the container, there is integrally formed therewith, actuating means 113, shown as an upwardly protruding member.

Rotatably housed within transverse hole 104 is pivoted locking means 120 comprising a cylindrical body or pin portion 120a, and outward end 1201; and an inward end 120c. inwardly extending from and raised up from and integrally formed with the inward end 120c is a semi-cylindrical portion 120d. Formed on said body portion 120 is a radially extending locking flange 120e for slidably engaging within groove 104a soas to rotatably support said pivoted locking means in said closure annular wall. The pivoted locking means further comprises a wing portion 120] integrally formed with the outward end 12% and extending radially away therefrom. The lower side portion 120fl of the wing portion is of sufficient dimensions so as to contact at least one portion of actuating means 113 when the closure is screw-tightened on the neck of the container.

Referring now again to the neck threads 112, there is a lowest thread portion 112b formed with semicylindrical groove 112a therein, said semi-cylindrical groove slidably, rotatably receiving the semi-cylindrical raised portion 120d of the pivoted locking means. The actuating means 113 is located at a point below said semi-cylindrical groove and is generally arcuately displaced from said groove in the direction of the lower end of said neck thread. This spatial relationship between the semi-cylindrical groove is dependent upon the wing portion configuration. This is so because, as the closure 101 is screw-tightenedon the container neck 111, the wing portion being vertically downward, the wing portion surface 120f1 contacts the actuating means 113 causing rotation of the pivoted locking means 120, thereby rotating the semi-cylindrical member 120d withing the semi-cylindrical groove 112a, as shown in FIG. 10. The pivoted locking'means 120 is thusly placed in a locking position. If desired, the wing portion may be manually aligned in a fully upright position as shown in FIG. 11, but this need not necessarily be done.

A child trying to remove the closure from the container would be unable to do so insofar as the semicylindrical portion I d is blocked by the semicylindrical groove 112a. To remove the closure, the wing portion must be returned to the original vertically downward position as shown in FIGS. 9 and 12.

In still another aspect of this invention the actuating means of the container may be eliminated and the pivoted locking member is manually rotated to the locking position. It is of course preferred to provide the actuating means so as to eliminate the need for manual lockmg.

While the aforesaid wing portion is generally perpendicularly disposed to said pivoted locking means, it is to be understood that the term perpendicularly, as used hereinbefore, thereinafter and throughout the specification and claims is to mean approximately as well as exactly perpendicular, as the case may be.

Although the description and drawings have primarily referred to container and cap, this is not meant to be construed or interpreted as limiting the invention or its application in any way. It can be used with any type of container or closure, and any material or method of construction; as well as any shape, and is so intended.
