LIFT CAP UP TO REMOVE It should be noted that the limited access closure depicted in the drawings herein relates, generally, to Example A, above, and also to subject matter of the Horvath US. Pat. No. 3,627,160; though the illustrated showing is not intended to be restrictive, and may take other forms, without departing from the spirit and the scope of the instant invention.
While child-resistant containers are successful in accomplishing their intended purpose toward small children, it has been found that certain adult groups have like-wise experienced at least a minor degree of frustration in opening them. For example:
a. Arthritics, or others, may lack the required manual dexterity.
b. Heart patients may panic if required medication is not immediately accessible; thus compounding their particular medical problem.
c. The visually infirm may find some alignment requirements to be beyond their physical capabilities.
d. 'Those endowed with a lesser than average degree of mechanical aptitude may also experience difficulty.
SUMMARY OF THE INVENTION It is therefor an object of this invention to provide a dual-mode container closure which permits the responsible user to select either limited (child-resistant) access to the stored materials, or unlimited (general) access to same. Whereas, households with vulnerable small children to protect, would obviously tend to select and use the limited access portion of the inventive closure; childless households could be free to utilize the unlimited accessportion, at-their option.
A further object of this invention is to provide a container closure which presents expanded gripping and leverage surfaces (when used in the limited access mode) without loss of any of its child-resistant capabilities. Whereas, households containing both small children PLUS elderly or infirm adults, may be assured that each group will be'served to the intended extent.
BRIEF DESCRIPTION OFTI-IE DRAWINGS Referring now to the drawings wherein:
FIG. 1 is a pictorial view of the inventive closure.
FIG. 2 is a side elevation (partially cut away) showing the inventive closure in the unlimited (general) access mode. 7
FIG. 3 is a side elevation showing the inventive closure in the limited (child-resistant) access mode.
FIG. 4 is a sectional view taken along line 4-4 of FIG. 3. FIG. 5 is a partial pictorial view showing the neck portion of 'a bottle adapted to receive and secured one form of limited access closure.
DETAILE DESCRIPTION oF THE DRAWINGS Referring again to the drawings, wherein like reference numerals designate like or corresponding parts throughout theseveral views; there is shown in FIG. 1 a preferred embodiment of the inventive reversible closure.
Closure 10 is comprised of stopper (or plug) portion 12 which may be integrally formed at flange 14D with cap (or skirt) portion 14. Removable disc 15, which rests atop inwardly projecting lugs 14A and 14B, fits snugly within cap 14 to form a secondary storage compartment within closure 10 itself, if desired, when said closure is utilized in the unlimited access mode of FIG. 2. Such an additional storage compartment would be especially useful for the daily storage of medicinal dosages. Of course, disc 15 must be removed when said closure is being utilized in the limited access mode of FIGS. 3 and 4.
As indicated in FIG. 3, stopper 12 represents the unlimited access portion of the closure 10, and cap 14 represents the limited access portion.
To attain the unlimited access (general) mode, as shown in FIG. 2, stopper 12 is inserted snugly into aperture 20A of bottle 20 until flange 14D becomes fully seated on mouth 20B. When this is accomplished, the cotton filler material 34 becomes downwardly compressed against pills (tablets, capsules or the like) 32 in the storage area of bottle 20; thus, allowing a minimum of vibration between pills 32 during shipment. Closure 10 may, of course, be pulled upwardly for easy removal from bottle 20.
In the limited access (child-resistant) mode, as shown in FIG. 3, cap portion 14 is placed over the neck por- Lug 14B is located along the same radial plain within a fi t cap eans on said closure having form ed cap 14 as corresponding lugs 14 An arrow Shaped thereon a securing surface for sealingly mating with b 14C th said access opening; ta on 6 Outer penphery of cap comcldes a second cap means extending from said first cap with the location of lug 14B.
