Application June 10, 1947, Serial No. 753,652
My invention relates to caps for poison containers.
The primary object of my invention is to safeguard children and adults in the handling of poison containers, by providing a container cap which is not easily removed, and which therefore cannot be removed through mistake.
A further object of the invention is to provide a cap for poison containers which will signal the potential user of the poisonous contents as soon as the container cap is touched.
A still further object is to provide a container cap of the above mentioned character, which is extremely simplified and therefore very practical and inexpensive to manufacture.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is a perspective View of a poison container provided with a cap embodying my invention,
Figure 2 is an enlarged fragmentary central vertical longitudinal section through the same,
Figure 3 is a view similar to Figure 2, showing the outer cap in position to be removed,
Figure 4 is a perspective view of caps, and
Figure 5 is a fragmentary central vertical longitudinal section through a modified form of the invention.
In the drawings, where for the purpose of illustration are shown preferred embodiments of my invention, attention is called first to Figures 1 to 4 inclusive. wherein the numeral I!) designates a poison container or bottle of any suitable shape and size. The container or bottle III is provided with the usual vertical cylindrical dispensing neck II, externallv screw threaded at its upper end as shown at I2.
Mounted upon the screw threaded neck I I, and having screw threaded engagement therewith, is an inner closure member or cap I3. This inner cap I3 comprises a cylindrical tubular internally screw threaded skirt portion I4, to engage over the screw threads I2, and a flat circular top I5, providing an inner annular shoulder It to engage upon the top of the container neck II to seal the same. The upper end of the inner cap I3 is externally screw threaded, as at H, and these screw threads I I extend downwardly for a short distance only, such as two full threads, and terminate a substantial distance from the bottom of 3 Claims. (Cl. 215-9) the cap. The external screw threads I! are adjacent to the top I5. The outside diameter of the skirt portion I4 is equal to or less than the minor diameter of the screw threads I'I.
The numeral I8 designates an external safety or signal cap for the poison container. This external cap I? includes a cylindrical tubular skirt portion I9, internally screw threaded at its lower end for a short distance upward, such as two full threads. These internal screw threads terminate a substantial distance from the top of the external cap, and they are designated by the numeral 20. The internal cylindrical surface 2I of the skirt portion I9, above the screw threads 2!) is preferably slightly undercut so that its diameter is greater than the outside diameter of the external screw threads IT. The internal cylindrical surface 2| extends upwardly axially above the internal screw threads 20 for a distance slightly greater than the axial dimension of the external screw threads I! on the cap I3. The external cap I8 further includes a flat circular top 22. providing a flat internal circular surface or shoulder 23 to engage upon the top I5, when the caps 23 and I8 are both applied to the container, see Figure 2.
In use, the inner cap I3 is applied to the screw threaded neck II of the container in the usual manner, and tightened to seal in the contents of the container. The external safety cap I3 is then applied upon the inner cap I3, see Figure 3, and the screw threads I1 and 20 enter into engagement. The external cap I8 is screwed down.- wardlyupon the cap I3, until the screw threads 2!! disengage or overrun the screw threads I'I. When this occurs the external cap I8 is loosely connected with the inner cap I3. and will not become disengaged therefrom. The loose connection exists because the diameter of the internal surface 2! is greater than the outsidediameter of the screw threads II, and the axial dimension of the surface 2| is greater than that of these threads. The screw threads 29 are now out of engagement with the screw threads H, and disposed beneath the same. see Fi ure and the cap I8 is free to turn in either direction unon the cap I3. There is also considerable axial clearance or end play between the caps I3 and I8, thus assembled. and the outer cap I8 will rattle u on the cap I3 when it is touched by the user. This rattling provides an audible signal to the potential user of the poison container as soon as the cap is touched.
In order to remove the caps from the container, it is first necessary to axially lift the outer cap [8, and to simultaneously turn the same, until the screw threads I! and 20 enter into engagement. When this has been done the outer cap I8 can be removed, but it is still necessary to remove the inner 'cap l3 to reach the poison contents. It is unlikely that a small child could understand the operations required to open the container. The caps provide a simple and safe closure means for poison containers, and are capable of wide application. It is desired to mold the caps 13 and I8 from suitableplastics material, but any other material desired may be employed. Obviously, the external design of the outer cap I8 may be varied as. desired.
In Figure 5, I have shown a modification or" the invention, wherein the numeral 24 designates a container, having a neck externally screw threaded at its upper end for a short distance downwardly only, as shown at 2B. The neck 25 is provided with an internal cork or stopper El, having a top. 28: which extends above the top of the neck 25., providing a flat seat or shoulder. The numeral 29 designates an external cap, similar to the cap I8 and provided with internal screwthreads 30 at its lower end which extend upwardly for a short distance only. Cap 18 has an internal. bore 3|: of greater diameter than the outside diameter of the screw threads 25%; and this bore is of suchv length that when the top 32 of the cap engages upon the top of the stopper 28, the screw threads 30 are. disposed below the screw threads 26 and. out of engagement therewith. When this condition exists the cap 29 is loose and freely rotatable in either direction.
The operation of the cap 29 is identical with the operation of the cap l8, and it is meant to serve the same purpose. The form of the invention shown in Figure permits the use or the loose fitting and signaling upon a container provided with a stopper. The advantages and safety achieved are the same as with the first form of the invention.
It is to be understood that the forms of my invention herewith shown and described are to be. taken as preferred examples of the same, and that various changes in the shape, size, and arrangement may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims.
Having thus described my invention, what I claim is:
1. A poison container including a member provided with external screw threads which terminate short of the. innerend of the member, a cap having internal screw threads adjacent to its inner end and which terminate short of its outer end and providedbetween its internal screw threads and its outer end with a recess which has a diameter greater than the diameter of the external screw threads of the member and an axial dimension greater than the axial dimension of the internal screw threads, the cap having an internal axial dimension greater than the axial distance between the inner end of the external screw threads of the member and the exterior free end of the member, the arrangement being such that the cap may be screwed up so that its internal screw threads will move inwardly upon I and its outer: end, the outer cap having an internal axial dimension greater than the axial distance between the inner end of the external screw threads of the cap and the exterior free end of the inner cap and the recess havingan axial dimension greater than the axial dimen-.. sion of the exteriorscrew threads, the-v arrangement being such that the outer cap may: be screwed up so that its internal screw threads. will move inwardly upon and inwardlybeyond; theex-v ternal screw threads of the inner cap, the ex-.v ternal screw threads of the inner cap being then positioned within the recess of" theouter cap sothat the outer cap may'rotate while the internal and external screw threads are out of" mesh.
3. A poison container including a neck provided with external screw threads which terminateshort of the inner end of the neck, a cap having internal screw threads adjacent to its inner end: which terminate short of its outer end and provided between its internal screw threads and its outer end with a recess which hasa greater diameter than the external screw threads of the neck and an axial dimension greater than the axial dimension of suchexternal screw threads, the cap having an internal axial dimension greater than the axial distance between the inner end of the external screw threads of the neck and the outer end of the neck, the arrangement being such that the cap may be screwed up so that its internal screw threads will move inwardly upon and inwardly beyond the external screw threads of the neck, the external screw threads of the neck being then rotatable within the recess, and a stopper for insertion within the neck.
