No. 777,723 Int. Cl. B65d 55/02 US. Cl. 21S-9 7 Claims ABSTRACT OF m DISCLOSURE A safety container closure for small plastic medicine bottles. A plug is inserted into the top or neck, in a tight friction-iit. The plug carries a key recess. An outer cap ts over the top of the container, and carries a key molded to it. The key is placed into the recess, and the plug engaged for withdrawal.
This invention relates to a safety-plug container closure of the type particularly adapted to contain medicine. While described with reference to ampules and the like, the medicament carrier may be in liquid form in the container. The device further relates to a container closure of the safety type wherein the contents of the container cannot be reached or exposed through a mere unscrewing, lifting or snapping-off action.
The prior art is aware of a variety of arrangements for preventing small children from opening medicine containers. In general, such devices include a closure member and some type of opening procedure or structure too complicated for a small child to comprehend and manippulate. Examples of such prior art devices are to be found in the following U.S. patents, although it will be understood that these arrangements do not represent the entire spectrum of such devices as known in the domestic art 2,793,777: 3,141,756: 3,160,301: 3,164,277: 3,181,718: 3,386,273. While these and other arrangements which are known in the art have been seemingly satisfactory and have presumably fulfilled their intended function they have in general been subject to various objections, such as cost of manufacture, reliability, and the like.
According to the practice of this invention, a novel arrangement of elements is employed for closing a container for medicine and includes a tight tting plug to seal or close olf the end of the container. A second closure or cap member ts over the first and also over a portion of the top periphery of the container. Entrance to the interior of the container is made possible by pulling olf the outer cap and then withdrawing the plug. The outer closure is provided with a tab or key, preferably integral therewith and which is inserted into a complementary aperture in the plug. The key is slightly rotated and is then pulled, thereby dislodging the plug. While it has already been known to employ a key slot in a closure plug for a container, and to withdraw the plug from the container by the insertion and pulling of a key element, as shown in U.S. Patent 124,277 to Marsh, the cooperation of elements according to the subject invention is different. Specifically, the key tab is an integral part of the outer closure to thereby preclude loss of the key. Further, it not only performs the function above described, but additionally serves as an abutment against which the thumb of the user may be placed to effect dislodgment of the closure from the container.
In the drawings:
FIG. l is an exploded view of a container, a plug and a top closure cap according to this invention.
FIG. 2 is a cross-sectional view of the top portion of a container, with the elements of FIG. 1 assembled.
3,473,631 Patented Oct. 21, 1969 FIG. 3 is a partially cut-away top view of the assembly of FIG. 2.
FIG. 4 is a View illustrating the plug withdrawal procedure.
FIG. 5 is a View similar to FIG. 3, but showing the opening tongue inserted in a slot in the plug.
Turning now to the drawings, the numeral 10 denotes a container of generally cylindrical form and according to present commercial practice formed of plastic. The container is adapted to contain ampules and the like, which define or carry various medicines such as anti-histamines, fungus produced drugs, etc. In general, such containers are rather small, typical dimensions being approximately two or three inches in height and one inch in diameter (six times two cm.). The side walls 12 of the container are of generally uniform thickness and are the same as the thickness of the bottom closure 14. The upper periphery of the container carries an integral and external bead 16 and the topmost portion of the interior of the periphery is chamfered or slanted away in a curved surface as indicated by the numeral 18.
The numeral 20 denotes a plug preferably formed of the same or a similar plastic as that employed in the construction of the container 10. The plug is defined by a generally circular top disc portion 22 from which depends an integral skirt 24. As illustrated, the skirt is tapered although it will be understood that it may be of uniform thickness. The numeral 26 denotes a curved surface extending completely around the periphery between the top surface edge of the disc 22 and the outer surface of skirt 24. The curvature and shape of the surface 26 is complementary to surface 18 shown in FIGURE 1. The numeral 28 denotes generally an aperture in the central portion of disc 22 and may be defined by the intersection of two slots. The lirst slot is designated by the numeral 30 and may be considered as a slot running parallel with one diameter of the disc. The second slot is designated by the numeral 32, and may be considered as intersection of a second diametrical slot which has a lesser length than slot 30 and intersects it at its medial portion at approximately 25 or 30 degrees.
The numeral 36 denotes an outer closure and is defined by a top disc portion 38 from which depends an integral skirt 40 whose lower and inner surface carries an integral bead 42. A key tab 44 is integral with the lower portion of the skirt over a limited angular extent thereof and is defined by a shank or neck portion 46 integral with the ange or skirt 40 and a radially outermost tongue portion 48 having side protrusions 49. The circumferential extent of the outermost portion 48 is only slightly less than the length of the slot 30, so that the entire key tab may be inserted through slot 30.
The elements above described are assembled as shown in FIGURE 2 of the drawing and it will be observed that the plug 20 makes a friction lit with the upper interior surface of the container 10. It will further be observed that the top surface of disc 22 is generally co-planar with the uppermost peripheral portion of the bead 16 of the container. A snap lit maintains the outer closure 36 on the container, with the annular bearing portion 43 of bead 42 abutting complementary portions 17 of bead 16. As shown at FIGURE 2, the axial extent of contact of the skirt 40 is such that the lower surface of the disc portion 38 abuts the top surface of disc 22 of the plug.
In use, with the container 10 closed or sealed as indicated at FIGURE 2, when it is desired to open and obtain access to the contents, the user grasps the container in one hand and with the thumb or other linger of the other hand pushes upwardly against the bottom surface of the key tab 44. This causes the closure to undergo displacement, with the bead 42 sliding over the bead 16. After the closure 36 has been entirely removed, it s manipulated as shown at FIG. 4 so that the key tab is opposite the opening 28. After insertion, as shown at FIG. 5, the clos-ure cap 36 is rotated in a clock-wise direction so that the outwardly flaring tips 49 assume a position underneath and slightly beyond the ends of slot 32. In this position, the closure 36 is now pulled and the plug 22 thus removed from the container. For replacement, the plug and top snap cap 3S are separated and the plug is first placed into position and then the cap snapped on, the bead 42 being pushed below the bead 16.
The above description has treated the cylindrical and plastic pill or ampule bottles currently in vogue. However, it will be observed that the invention displays utility as a closure for cross-sections other than circular, as well as with containers having distinct neck portions. While the plastic arts embrace a variety of manufacturing techniques, it has been found that injection molding of the several components of the invention will yield commercially acceptable quality.
