SAFETY CLOSURE HAVING LOCKING RING BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to safety vials for storage of dangerous drugs and the like.

2. Description of the Prior Art Numerous safety vials have been proposed which include relatively complex caps having rotatable rings therein which are formed with notches that must be appropriately indexed with respect to lugs carried on the container in order to remove the cap from the container. Many of the containers of this type are objectionable because they are expensive to manufacture and require a high degree of alertness and dexterity to operate. Other combination containers have been proposed that include a first continuous flange disposed around the neck thereof and a second flange which is formed with peripheral notches. A cap assembly is provided which includes a cap liner that has a cap shell rotatably assembled therewith. The cap liner includes resilient flanges which hook below the continuous flange and are normally held in engagement therewith by the cap shell, such shell including lugs engaged below the notched flange. The cap shell is rotatable to a release position for releasing the fingers and when the liner is properly indexed with respect to the container, the lugs will pass upwardly through the notches in the notched flange to release the cap assembly for removal. A combination closure of this type is shown in US. Pat. No. 3,033,406. However, combination closures of this type suffer the shortcoming that they are relatively expensive to manufacture and an unauthorized person attempting to gain access thereto can determine the rotational position required for release of the cap shell and liner by feel as the shell and liner are rotated to the release positions.

SUMMARY OF THE INVENTION The combination closure apparatus of present invention is characterized by a container which is open on its top end and has a coaxial ring rotatably connected therewith. The container and ring include respective first and second lugs and a cover is provided which includes a neck that telescopes inside such ring and container and is formed with a pair of spaced apart continuous peripheral flanges that are formed with vertically aligned notches for passage of the lugs. lndicia is provided on the cover, ring and container for indicating when the ring lug is aligned with the container lug and when the notches in the cover are aligned with such lugs for convenient removal of the cover.

An object of the present invention is to provide a combination closure apparatus of the type described which is relatively convenient to operate so it can be operated by sick and feeble patients.

Another object of the present invention is to provide a combination closure apparatus of the type described which makes it highly difficult for unauthorized persons to gain access thereto.

A further object of the present invention is to provide a combination closure apparatus of the type described which can easily be assembled by a druggist or the like from a supply of components to provide a desired combination therefor.

A still further object of the present invention is to provide a combination closure apparatus of the type described which is pneumatically sealed.

These and other objects and the advantages of the present invention will become apparent from a consideration of the following detailed description when taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT The combination closure apparatus of present invention includes, generally, an upwardly opening container 31 having a locking ring 33 rotatably connected therewith. The container 31 and ring 33 include first and second sets oflugs 41 and 51. A cover, generally designated 55, is provided with a downwardly projecting neck which includes a pair of vertically spaced apart flanges, generally designated 57 and 59, thereon which are each formed with three respective vertically aligned notches 61 and 63. Consequently, the ring 33 may be rotated to align the lugs 51 with the respective lugs 41 of the container 31 and the cover 55 attached with such lugs passing through the respective notches 61 and 63. The cover 55 and ring 33 may then be rotated relative to the container 31 to dispose the lugs 41 and 51 out of alignment with the notches 61 and 63 in engagement below the respective flanges 57 and 59. When the container 31 is to be opened, the ring 33 may be rotated to realign the lugs 51 with the lugs 41 and the cover rotated to align the notches 61 and 63 with such lugs to release such cover for convenient removal.

Referring to FIGS. 1 and 3, the container 31 is generally cylindrically shaped and is formed on its interior with the three equally spaced downwardly raked pointed lugs 41 which are all of different width. The cover 55 is formed with a downwardly projecting neck which has the flanges 57 and 59 formed on the periphery thereof.

Referring to FIGS. 3 and 5, the flanges 57 and 59 are formed with respective upwardly and outwardly angled shoulders 65 and 67 which define grooves 68 and 69 that are shaped to complement the shape of the respective lugs 41 and 51.

The upper end of the sidewall of the container 31 is formed with a peripheral continuous coupling groove 71 which projects downwardly in such sidewall and is formed on its lower extremity with an enlarged-in-cross section arrowhead-shaped chamber 73 which defines a pair of oppositely disposed downwardly facing shoulders 75 and 77. The locking ring 33 includes a circularly shaped downwardly projecting resilient coupling tab 81 which is formed on its lower extremity with an enlarged-in-cross section head 83 which is angularly shaped in cross section to complement the shape of the chamber 73 and engage behind the shoulders 75 and 77. The coupling tab 81 fits snugly in the coupling groove 71 but forms a sufficiently loose fit to provide for relatively free rotation of the lockingring 33.

The container 31 includes an upwardly pointing indexing arrow 91 and both the ring 33 and cover 55 have respective in- I dexing indicia 93 and 95 on the peripheries thereof. Naturally,

this indicia may be of any desired type and may be in the form of raised or depressed forms to be perceived by feel for operation by a blind patient.

In operation, a pharmacist may stock a quantity of the containers 31, rings 33 and covers 55 for assembly at the time a prescription is filled to provide a closure apparatus which may be made of somewhat resilient plastic and the lock ring may be installed on the container by merely pressing the coupling tab 81 downwardly in the receiving groove 71 to compress the locking head 83 for passage downwardly through the groove 71 and subsequent expansion within the locking chamber 73 to engage behind the shoulders 75 and 77 to positively prevent removal thereof.

In the particular apparatus shown in FIG. 1, the combination selected is 53 whereby the numeral 5 on the cover 55 and numeral 3 on the lock ring 33 must be aligned with the indexing arrowhead 91 on the container 31. Consequently, the prescription is placed in the container 31 and the lock ring 33 rotated to align the numeral 3 thereon with the indexing arrow 91 to thereby align the lugs 51 over the lugs 41 with the lugs of corresponding width in direct vertical alignment with one another. The cover 55 may then be installed by aligning the numeral 5 of such cover over the indexing arrow 91 and inserting the neck of such cover downwardly through the ring 33 to enable the respective lugs 41 and 51 to pass through the notches 61 and 63 of corresponding widths. Thereafter, both the cover 55 and ring 33 may be rotated to move the notches 61 and 63 out of alignment with the lugs 41 and the lugs 51 out of alignment with both the container lugs 41 and such notches. Consequently, the prescription will be locked securely within the container 31 and any attempt to forcibly pull the cover 55 from the container 31 will merely wedge the lugs 41 and 51 more securely into the respective grooves 68 and 69 to retain such cover in position.

The patient will be given the combination of 53 and such combination may be typed or otherwise inscribed on the back of the label attached to such container whereby the patient will have access thereto in case he forgets the combination. It will be noted that efforts to gain unauthorized access to the prescription within the container 31 will be relatively futile since the ring 33 may be rotated to numerous different rotational positions with respect to the container 31, and the cover 55 may also be rotated to even more positions relative to the ring 33 and the container 31 thereby providing a multiplying improbability of the correct combination being selected. Further, since the lugs 41 and 51 engage behind both the flanges 57 and 59, a party rotating the ring 33 and cover 55 in attempt to feel alignment of the lugs 41 and 51 with the notches 61 and 63 will be unsuccessful since, even if he is successful in aligning the notches in either flange 57 or ,59 with either set of lugs 41 or 51, the other set of lugs retain the cover 55 securely in position thereby preventing such person from sensing that the notches 61 or 63 are appropriately aligned with the corresponding set of lugs 41 and 51. Further, the fact that each lug in the respective sets of lugs 41 and 51 are ofdifferent widths and that the notches 61 and 63 are correspondingly of different widths, dictate that the lock ring 33 and cover 55 must be clocked to the correct relative rotational position with respect to the container 31 to enable the ap propriate lug 41 and 51 to pass through the notch 61 or 63 of corresponding width.

When the prescription is to be used, the patient merely rotates the ring 33 to align the numeral 3 over the arrow 91 and holds such ring stationary while he rotates the cover 55 to also align the numeral 5 with the arrow 91 thereby positioning the lugs 41 and 51 of equal widths in vertical alignment and aligning the notches of corresponding widths 61 and 63 therewith as shown in FIG. 6 to release such cover for being removed.

The combination closure apparatus shown in FIGS. 2, 4 and 7 is similar to that shown in FIG. 1 except that the container 101 is provided with a peripheral interior flange, generally designated 103, surrounding its opening and formed with a plurality of vertical notches 105. The lock ring, generally designated 107, is also formed with a peripheral interior flange 109 having a set of through vertical notches 111 therein for selective alignment with the notches 105. The cover, generally designated 113, is formed with a downwardly projecting neck having two sets of vertically spaced apart and vertically aligned exterior lugs 115 and 117 for selective receipt in the notches 111 and 105. Consequently, the container shown in FIGS. 2, 4 and 7 is operated the same as the container shown in FIG. 1 except that the lock ring 107 is rotated to align the notches 111 with the notches of corresponding width and the cover 113 is rotated to align the lugs 115 and 117 with the notches 105 and 111 of corresponding width to thereby free such cover for removal.

The combination closure apparatus shown in FIG. 8 is also similar to that shown in FIG. 1 except that the container, generally designated 121, is formed with two sets of exterior lugs 123 and 125. The lock ring, generally designated 127, is formed with an interior inwardly projecting flange 129 having a set of notches 131 formed therein for passage of the respective lugs 123 and 125. The cover, generally designated 131, is rotatably secured to the locking ring 129 and is also formed with an inwardly turned peripheral flange 133 having a set of notches 135 formed therein for passage of the respective lugs 125.

Still referring to FIG. 8, the locking ring 127 is formed with an upwardly opening circular coupling groove 139 which is formed in its lower extremity with an arrowhead-shaped enlarged chamber 141. The cover 131 is formed with a downwardly projecting coupling tab, generally designated 143, which is formed on its lower extremity with an enlarged arrowhead-shaped head for receipt in the chamber 141. Consequently, operation of the closure apparatus shown in FIG. 8 is substantially the same as that for the closure apparatus shown in FIG. 1 except the cover 131 and ring 127 are coupled together for relative rotation and require that the respective notches 131 and 135 of corresponding widths be aligned over one another for passage of the lugs 123 and 125 to enable the cover 131 to be removed from the container 121.

The, closure apparatus shown in FIG. 9 is a modification of the closure apparatus shown in FIG. 8 and includes a container, generally designated 151, which is formed with backto-back inner and outer peripheral flanges 153 and 155 which have respective notches 157 and 159 formed therein for receipt of respective lugs 161 and 163 depending from the respective cover, generally designated 167, and the lock ring, generally designated 169. Consequently, the cover 167 and lock ring 169 are coupled together for relative rotation whereby the lugs 161 and 163 may be aligned with the respective notches 157 and 159 to enable the combination lock ring and cover assembly to be removed from the container 151.

The combination closure apparatus shown in FIGS. 10, 11 and 12 includes a container, generally designated 173, formed with a set of inwardly projecting lugs having a radially inwardly projecting and upwardly angled resilient seal skirt 177 disposed therebelow. A locking ring, generally designated 179, is rotatably mounted on the container 173 and includes a set of inwardly projecting lugs 181. A cover, generally designated 185, is provided and includes a downwardly pro jecting neck having a pair of vertically spaced peripheral exterior locking flanges 187 and 188 formed thereon. The lower extremity of the neck terminates in a downwardly projecting and radially outwardly angled resilient seal skirt 189 for engagement with the sealing flange 177 as shown in FIG. 11. The locking flanges 187 and 188 are each formed with a set of upwardly opening respective sockets 191 and 193 disposed equidistant thereabout for selective registration with downwardly projecting balls 195 and 197 depending beneath the respective lugs 175 and 181. Consequently, the cover 185 may be placed on the container 173 and both it and the locking ring 179 rotated as a unit to register the sockets 191 and 193 with the respective balls 195 and 197 to press the cover 131 downwardly to the position shown in FIG. 11 to positively engage the sealing skirts 189 and 177 with one another to provide an airtight seal.

From the foregoing detailed description, it will be apparent that the combination closure apparatus of present invention provides a convenient and foolproof means for maintaining prescriptions and other dangerous drugs under lock whilc locked in a closure which is relatively convenient to open by a person having the combination therefor. Further, the combination closure apparatus is relatively straightforward in design and economical to manufacture thereby making it feasible for such apparatuses to be sold after the drugs furnished therein have been used.

Various modifications and changes may be made with regard to the foregoing detailed description without departing from the spirit of the invention.
