ABSTRACT: A closure cap generally of the screw-on type having exterior knurls at the periphery thereof, in combination with a safety overcap having complementary interior knurls and including yieldable, resilient interior filaments or pins maintaining the overcap rotarily unengaged with respect to said closure cap, but said knurls engaging upon the application of downward pressure on the safety overcap relative to the closure cap.
BACKGROUND OF THE INVENTION It has been a longstanding problem to provide against accidental or unauthorized opening of containers for e.g., pharmaceuticals, etc., especially by children. .Many suggestions have been made but in most cases the constructions involved are too expensive or too complicated for average or everyday use. The present invention provides an inexpensive but efficient construction normally preventing the unauthorized opening of containers particularly those having a more or less standard bottle cap of the screw-on or bayonet slot type and having a knurled or toothed periphery.
SUMMARY OF THE INVENTION The invention in this case contemplates in general the use of a more or less conventional bottle closure cap which is usually made of metal or of any other suitable material, which is adapted to screw onto the mouth of the container or to be secured thereto by similar rotarily actuated means as for instance cams, bayonet slots, all as is well known in the art.
In the present case this closure cap is provided with a knurled peripheral edge adjacent the top portion thereof, said knurled edge presenting a continuous series of teeth to provide a better grip for opening and closing the container by turning the closure cap. Such closure caps or equivalents are well known.
There is applied to the bottle closure cap a separate safety overcap which can be conveniently and inexpensively made, e.g., of suitable plastic or metal. This safety overcap comprises a base more or less conforming to the base of the closure cap and it has a peripheral skirt ending in an inturned lip which is snapped over the open usually crimped, edge of the skirt of the closure cap holding the two caps together as a unit.
The peripheral skirt of the overcap has a width (height) greater than the width (height) of the corresponding skirt of the closure cap. The skirt of the overcap has interior knurls complementary to those at the exterior of the closure cap, but those on the overcap are located adjacent the base thereof an the skirt in the area of its inturned lip is free of such knurls. At the interior of the base of the overcap, it is provided with a series of free-ended flexible resilient filaments or pins arranged normal to the base. These filaments or pins are in position to maintain the inturned lip on the skirt of the overcap adjacent the crimped edge of the skirt of the closure cap, and the base of the safety overcap in spaced relation with respect to the base of the closure cap, so that the respective knurls are out of engagement with each other.
In this situation, the safety overcap may be rotated freely with respect to the container and its closure cap and thus can not turn the latter in either direction; but when downward palm pressure is applied to the safety overcap, it moves downwardly in relation to the closure cap and the aforesaid filaments or pins yield to allow engagement of the knurls on the two caps thereby forming a positive interconnection between the overcap and the closure cap whereby the latter is turned as the overcap is turned in either direction, both to open the container and to close it.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view in elevation with parts broken away and in section illustrating the present invention with the safety overcap unengaged with respect to the container closure cap;
FIG. 2 is a similar view but showing the safety overcap engaged with respect to the closure cap in position for turning the same in either direction;
FIG. 3 is a bottom view of the interior of the overcap, part being broken away and in section and illustrating the freeended filaments or pins; and
FIG. 4 is a section on line 4-4 of FIG. 2.
PREFERRED EMBODIMENT OF THE INVENTION The reference character 10 indicates a container which may be any kind of bottle or jar. Such a container may be provided with a neck 12 and as shown it has a screwdhreaded indented construction as indicated at 14 for the reception of a closure cap generally indicated at 16, the latter having a skirt with an indented thread 18 for the purpose of securing the closure cap to the container as is old and well known in the art. Ordinarily such caps are provided with a crimped outwardly extending lip 20 at the open end thereof and they also have a closed portion or base which is indicated at 22 in FIG. 1. Any other similar connecting structure may be used to carry out the purposes of this invention, wherein the cap 16 is rotated relative to the mouth of the bottle or container 10 to open or close the same. Such caps are often knurled or toothed at their peripheries as at 24 for better grasp thereof.
The safety overcap 26 may be made of plastic or any other useful or convenient material, but in any event preferably it is molded in one piece. It has a closed portion or base 28 conforming in general to the base 22 of the bottle cap 16, and at the periphery of the base there is a depending skirt or flange 30 which extends continuously about the edge thereof. The skirt 30 terminates in an inturned lip 32. The skirt 30 has a width (height) greater than the width (height) of the corresponding skirt portion of the closure cap. The lip 32 underlies the edge at 20 of the closure cap 16 and permanently connects the two caps together. Skirt 30 has interior knurls, teeth, etc., 34, at its periphery complementary to those at 24 but located adjacent the base 28, the interior of the skirt below the knurls being plain.
Arranged interiorly of the safety overcap 26 a series of preferably molded-in, free-ended filaments or pins 36 which extend generally at a right angle with respect to the plane of the base of the overcap 26. These filaments or pins may be arranged as convenient, e.g., in a circle, cross, e.g., as clearly shown in FIG. 3 and they have a length which is substantially equivalent or less to the excess of the width of the skirt 30 of overcap 26 with regard to the corresponding skirt of the closure cap 16.
The filaments or pins 36 are deformable and resilient and normally they maintain the relative position of the overcap with respect to the closure cap in the position shown in FIG. I, where there is no positive engagement between the two caps and wherein rotation of the safety cap 26 does not result in any corresponding rotation of the closure cap 16.
It is only when the palm is pressed downwardly for instance in the direction of the arrow in FIG. 2 that the filaments or pins 36 are'deformed, see FIG. 2, and allow the knurled or toothed portion 24 at the periphery of the closure cap to engage and clutch to the like conformation at 34 of the safety cap. In other words, when pressure is applied in a downward direction to the overcap as explained above, and the knurls or teeth form a mechanical interconnection between the overcap and the closure cap by which means the closure ca is then easily turned in either direction to open and close the container 10, by rotating the safety overcap.
I claim:
1. The combination with a rotarily actuated closure cap for a container, and means for connecting the closure cap with respect to the container when the cap is turned in one direction, said cap being released from the container when the cap is turned in the opposite direction of a safety overcap, an inturned flange on the overcap connecting the two caps with respect to each other with the flange under the periphery of the closure cap and the safety overcap in superimposed relation to the closure cap, said caps being capable of a relative motion in an axial direction,
