6 Claims.
This invention relates to receptacle closures and more particularly to safety closures which are not readily loosened or removed from the receptacle or contatiner to which they are applied, whereby unauthorized or incompetent persons may be deterred from access to the containers.
The general object of the invention is the provision of a novel and improved safety closure of the class described which is of simple and economical construction, easy to manufacture, and effective in accomplishing its purpose. However, the novel closure, at the same time, is readily re- -movable by the use of one of a variety of simple household implements or other readily available accessories, but in a manner beyond the easy comprehension of a very young person or a person not entirely in possession of his faculties.
A very obvious practical application of my invention is its use in connection with caps or stoppers for bottles containing antiseptics, medicines, or poisons in homes where thereare young children, or in hospitals for the treatment of certain classes of patients. a
The invention in its preferred embodiment con templates the provision of a bottle, jar, or other necked container having a screw threaded cap applied thereto, the threaded body of the cap being substantially completely covered by a freely floating guard or casing capable of substantially frictionless rotative movement with regard to the body of the cap, or at least with a smaller degree of friction than that between the threaded contacting portions of the container and the body of the closure, or that between the container mouth and the closure gasket or washer. It is of course necessary that any area of the inner body part of the closure which may be exposed, be insuilicient to afford a grip by any ordinary manual means to efl'ect the unscrewing of the closure.
To permit the closure cap to be removed to provide access to the contents of the container, openings or recesses are provided in the inner cap body and in the outer casing which may be brought into registry by relative rotation of these members. With the openings in registration, an implement-preferably one of common use-may be inserted in both and the two parts of the closure rotated in unison until the cap is unscrewed. In the preferred form of the invention,
the openings comprise elongated narrow kerfs made in the two ordinarily independently movable members, so that a thin bladed instrument or object, suchas an ordinary table knife, a nail file, a letter opener, a coin, or the like may be used to interlock the members for simultaneous rotation.
Other objects and features of novelty will be apparent from the following specification when read in connection with the accompanying drawing in which certain embodiments of the invention are illustrated by way of example.
In the drawing:
Figure 1 is a vertical sectional view of. the upper part of a bottle and closure embodying the principles of my invention;
Figure 2 is a similar cross sectional view taken at right angles to Figure 1;
Figure 3 is a, top plan view of the container and closure;
Figure 4 is a fragmentary top plan view showing the two slots or kerfs in the respective elements of the closure, in displaced positions;
Figure 5 is a vertical sectional view similar to Figure 1 and showing a modified form of the invention;
Figure 6 is a vertical sectional view of another tainer to which the invention is applied comprises the bottle] l0 having the neck II which is provided with the screw threads [2. The safety cap of closure which is applied to the bottle is indicated generally by the reference numeral l5 and comprises the inner body member l6 preferably made of a suitable plastic material and internally threaded as at I! to correspond to the threads I! of the'bottle neck. Between the inner side of the top wall ll! of the member l6 and the upper edge I9.of the mouth of the bottle, there is interposed a washer or gasket 20 which may be made of any suitable slightly compressible composition of felted, laminated, fibrous, or plastic nature. It will be readily understood that when the member I6 is screwed upon the neck of the bottle, the gasket I6 will be compressed and suflicient friction to retain the closure tightly secured to the bottle will be developed between the cap IS, the gasket 20, and the bottle neck. Friction will also be. set up between the threaded parts of the bottle and cap.
In order to prevent the displacement or removal of the cap by unauthorized or incompetent persons, the inner cap I6 is enveloped by an outer guard member or casing 22 which inthis particular embodiment is made of sheet metal. The side walls of the casing 22 and also the top wall 23 of that member are preferably designed so as to fit snugly the outer contour of the inner member l6 but without any substantial friction when the parts are rotated relative to each other. In order to prevent the removal of the casing from the inner part of the cap the lower edges of the cylindrical portion are spun or turned under as at 24 to underlie the bottom edges of the inner member It.
The top wall ii of the inner member I3 is provided with a groove 25 which, in this embodiment.
extends entirely across the top of the member is and opens laterally outwardly at the ends thereof. The groove or slot 25 is preferably rather narrow, not much wider than the thickness of a knife blade or of a coin of medium size. A slot 21 of substantially the same width as the kerf or groove 25 is formed in the upper wall 23 of the ordinarily freely rotatable shell or casing member 22, and this slot also extends entirely,
try with the slot 31 of the inner member and a thin instrument such as the end of a knife blade or a coin may be inserted in the slots 31 and 48, interlocking the two elements of the cap, and permitting the removal thereof by a rotation of the outer casing. The gasket 35 may have a depressed central portion 41 to accommodate the inner end of the locking instrumentality.
Another embodimentof the invention is illustrated in Figure 6 of the drawing in which the inner member 53 is of sheet metal and is enveloped by an outer casing 52 of plastic or similar material, the two members being held together by means-of flanges l3 and 54 formed on the respective parts. The central portion of the top wall of the inner member 50 is pressed or Then, in order to reapply the cap, the thin or bladed instrument is reinserted in the registering groove and slot and the cap screwed on to the vbottle neck, suflicient pressure being applied to develop enough friction to retain the cap securely in place. Then after the tool or interlocking instrument is removed, the outer cap portion or casing 22 may be rotated through an angle of less than 180 to bring the slot 21 and the groove 25 into relatively displaced positions, as clearly shown in Figure 4 of the drawing.
In Figure 5 of the drawing, a modified form of the invention is shown in which there is applied to the neck I I of the bottle it a safety cap designated generally by the reference numeral 30 and comprising an inner threaded member 32 made of sheet metal and adapted to be screwed onto the neck of the container. The upper wall 33 of the inner member is provided with shoulders 34 which bear upon the margins of the gasket 35 which rest upon the upper end of the neck of the bottle, and the central portion of the wall 33 of the inner member israised as at 36. This raised portion is provided with a central transverse slot 31.
The metal inner member 32 of this form of the safety cap is enclosed by an outer guard member or casing which is preferably made of plastic or ceramic material and is arranged to loosely enclose the inner cap member for substantially frictionless relative rotative movement. The casing 40 is retained upon the inner metal member 32 by means of the interfltting or overlapping of 46 which may be brought into substantial regis- 7i bulged upwardly to form two semi-circular raised areas I! having a groove 3' formed centrally and extending transversely of the cap. The outer member 52 is provided in its top wall 58 with a slot 30 which may be brought into registry with the groove portion. and the members interlocked by a suitable instrument as in the case of the embodiments previously described. In this case, the inner cap member is not perforated and there is thus no possibility of leakage.
In Figure 8 there is shown still another embodiment of the invention in which the inner threaded metal closure portion 65 and the outer, preferably plastic casing portion 66 are rotatably secured together-by means of the rivet 61, or other similar fastening element, in the central portions of their upper walls. A gasket 68 is provided with a depressed central portion to accommodate a pointed instrumentality such as suggested at 69 which is adapted to be inserted through the registering small openings It and H in the upper walls, of the elements 66 and 65 respectively.
'These openings II and II are displaced radially It will be further understood that various changes and modifications may be made in the embodiment illustrated and described herein without departing from the scope of the invention as defined by the following claims.
