1 mwamrm l |SHAL J MAHKOWITZ SAFETY AEROSOL COVER CAP The present invention is a continuation-in-part of my copending application. Ser. No. 680,937. filed Nov. 6, I967, now U.S. Pat. No. 3,462,045. and entitled Safety Aerosol Cover Cap."
BACKGROUND OF THE INVENTION This invention relates to aerosol and pressurized containers of the type which are used for packaging and dispensing various products and to a method of assembling a safety two-piece cover cap as a unitary one-piece assembly to the container. In my copending application identified hereinabove, there is disclosed a novel safety cover cap construction for use specifically with aerosol containers. One of the disadvantages of said structure is its two-piece construction which of necessity requires two or more separate operations for assembling the cover cap to an aerosol container. Such multiple assembly steps comprise at least a separate assembly step for each of the cap elements which clearly increases the overall cost of providing a safety aerosol cover cap device. It is therefore, a purpose of the present invention to overcome this disadvantage and to provide a unique two-piece safety cover cap assembly which can be assembled to an aerosol container in a relatively simple operation.
Accordingly, it is a primary object of the invention to provide a safety aerosol cover cap which can be assembled to an aerosol container in one simple step.
A further object of the present invention is to provide a safety aerosol cap, of the above character, which can be economically manufactured and assembled. which is relatively simple in constructure, and easy to use.
Other object and advantages will appear hereinafter.
In the drawings accompanying this specification, similar characters of reference are used to designate like components throughout the several views, wherein:
FIG. I is an exploded perspective view, partly from above, of the elements of the present invention, together with a dispensing aerosol container of the type described.
FIGS. 2 and 3 are bottom views of both the upper and lower safety cover cap elements; and
FIG. 4. is an assembled sectional view taken along line 4-4 of FIG. I, further showing the details of the cover cap elements.
Referring now to the drawings, the aerosol or pressurized container is generally of the size adapted to be held by'the hand of a user. Such container is invariably of metal and has a cylindrical sidewall l2 terminating in annular beads I4 and 16. The top portion of the aerosol container 10 generally comprises a conical neck portion 18 which is closed by both the annular bead l4 and another upper annular bead 20 formed about the valve assembly opening 22. A valve-actuating button 24 extends upwardly from a valve stem 26 which is connected to a suitable valve assembly (not shown) and associated dip tube (also not shown) residing within the container 10 and being supported from the valve assembly opening 22.
The unique cover cap structure of the present invention is shown as comprising a lower cap element 28 and an upper cap element 30. The lower cap element 28 is rotatively secured in a loosely fitting manner about a suitable annular bead at the top of the container, such as the upper annular bead 20. An upper cap element 30 is securely fastened to the lower cap element 28 by means of suitable fasteners. such as threads, bayonet joints. etc. In the preferred example shown herein, a threaded connection 32 is provided between the upper and lower cap elements 28 and 30. This two-piece safety cover cap structure appears on the whole to the user as a one-piece assembly which is just like any other ordinary cover cap striicture. The main difference is, of course, in its function and operability.
order to open same for use. one must first recognize the secret for revealing or showing the aerosol button. As shown in said copending application, in order to open the container, one must first hold the container 10 and the lower cap element 28 in a fixed position with one hand and rotate the upper element cap element 30 with the other hand so as to unthread the cap elements from each other. The lower cap 28 element will remain on the bead 20 inasmuch as the aperture 32 in the radially inwardly extending flanged portion 34 is snapped about or forced over the bead 20 in such a manner that it still rotates freely thereabout although being fixedly retained in an axial position.
As best shown in FIG. 2, the lower cap element 28 is provided with ribs 33 beneath the flanged portion 34 and adjacent the sidewall 35 for reinforcing the structural rigidity of same. The aperture 32 is provided with suitable edge means 36 which facilitates mapping the lower cap element 28 about the bead 20. Within the upper cap element 30 is a downwardly extending cylindrical hollow tubelike member 38. This member 38 bears against the flanged portion 34 about the aperture 32 when the cap elements 28 and 30 are together as a unitary one-piece unit.
In the method of assembling the novel safety aerosol cover cap to a container, the upper and lower cap elements 28 and 30 are assembled to the container in one step as a unitary assembly. The tubelike member 38 reinforces and backs up the flanged portion 34 as the aperture 32 and edge means 36 of the flanged portion 34 is pressed about the bead 20. This tubelike member 38 is a critical feature of the upper cap element 30 without which the safety cover cap unit could not be assembled in a speedy, economical manner. The ribs 33 further reinforce and strengthen the flange portion 34 of the lower cap element 28.
The bottom edge 39 of the outer wall 40 of the upper cap element 30 resides and is seated within a small channellike groove 42 formed at the bottom outer periphery of the lower cap element 28. Am upwardly turned edge 44 of the lower cap element 28 facilitates concealing the separate nature of the two cap elements and further aids in retaining the wall 40 of the upper cap element 30 from being snapped off the lower cap element 28 should the threads be forced and broken apart by the twisting and bending of the upper cap element by a child who is determined to open the device.
It will be appreciated that the safety aerosol cover cap shown and described herein is only a preferred example of the invention and that various modifications and changes in the size, shape and arrangement of parts may be resorted to without departing from the scope of the appendant claims.
