3 Claims. (Cl- 215-9) This invention relates to caps for bottles and more particularly to screw caps.
An object of the present invention is to provide a safety screw cap particularly designed for use on bottles containing a poison or the like and which is of such a construction, combination and arrangement of parts as only one thoroughly familiar with the structure of the cap can, other than by chance, properly remove the cap from the bottle.
The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawing wherein:
Figure 1 is a view showing in section the improved cap with the parts so arranged as to permit the relative movement thereof.
Figure 2 is a view similar to Figure 1 with the parts so relatively arranged and engaged as to transmit movement of one part of the cap to the other to effect a removal or replacement of the cap.
Figure 3 is a detail view taken substantially on the line 33 of Figure l, and
Figure 4 is a sectional view through the outer or false cap member.
Referring to the drawing by reference numerals it will be seen that the cap, in the preferred embodiment thereof, comprises in accordance with the present invention a main cap I consisting of a suitably shaped body, preferably a cylindrical body having a threaded socket portion 8 for the threaded reception of the neck 9 of a conventional bottle I0. If desired there may be suitably arranged in the inner end of thesocket of the cap I a cork or other sealing element II.
The cap member 1 is housed within what may be termed a false cap member I 2.
The cap'member I' 2 which may be formed of metal or other suitable material is materially larger than the cap member 1 and is in the form of a closed casing except for an opening I3 in the bottom thereof: registering with the socket 8 and accommodating the neck 9 of the bottle III.
The cap member;'I- 2- is normally loosely mounted with respect tofthe cap member I so that the member I2 may be'rotated or otherwise manipulated without normally affecting the cap member I.
Further in accordance with the present invention the cap member I in the crown thereof is provided at any two desirable points thereon with sockets or recesses I4 while the cap member I2 on the under side of the crown part thereof is providedwith protuberances or pins I5 cooperable with the sockets It for placing the cap member I2 in such engagement with the cap member I that a rotative movement of the member I2 will be imparted to the cap member I either for screwing the cap onto the neck or for unscrewing the cap from the neck of the bottle.
Interposed between the crowns of the cap members I and I2 is a spring device in the form of a disk I6 of spring metal or the like secured to the crown of the cap I at the center of said crown and in any suitable manner, Radiating from the disk 6 are upwardly directed curved fingers I! that normally engage the crown of cap I2 to yieldably hold the crown of the cap I2 raised with respect to the crown of the cap 1 and consequently the projection I5 out of engagement with the recesses I4.
From the above it will be apparent that normally the cap members are in the relative position shown in Figure 1.
When for example it is desired to remove the cap from the neck 9 a downward pressure is exerted on the cap member I2 against the opposition of spring fingers I1 and the member I2 is also properly rotated relative to the member 1 to position the protuberances or projections I5 into engagement with the recesses I4 for locking the cap members I2 and I together. When thus locked together rotative movement of the cap member I2 in the proper direction will be imparted to the member I for unscrewing the member I to remove the cap from the bottle.
To replace the cap pressure is exerted on the cap member I2 to engage the projections I5 with the recesses I4 and while so engaged the rotation of the member I2 in the proper direction will result in a transmission of movement to the member I for threading the same onto the bottle neck 9.
It will be seen that a cap of this character will require certain knowledge on the part of the user as to the construction of the cap before a removal of the cap can be eifected other than perhaps by chance. Thus a cap of this character will be especially useful for use by druggists and the general public for containers containing poison or other kinds of medicine or the like that is not to be opened by children or persons under irrational impulses.
Having thus described the invention, what is claimed as new is:
1. In a cap of the character described, inner and outer complemental cap members, said inner cap member fitting loosely within the outer cap member, a disk interposed between the crowns of said cap members and secured to the crown of the inner cap member, and upwardly directed curved fingers integral with the edge of said disk and engaging the crown of the outer cap member for yieldably retaining the crowns or said capmembars in spaced relation, and inter-engaging means on the'crowns oi. said cap members adapted to be'engaged in opposition to said fingers for transmitting movement of the outer cap member to the inner cap member.
2; A cap for bottles or the like comprising an inner cap adapted to be applied to a bottle or the like by turning it, an outer cap covering the inner cap. means retaining the caps assembled but permitting relative rotary movement thereof, a spring device interposed between the crowns 0! said cap members yieldably spacing said crowns apart, said inner cap member having recesses in the crown thereof, and said outer cap member and normally free to rotate relative to the main cap member, a spring device interposed between the crown ends of said cap members for normally spacing said crown ends relative to one another, and inter-engaging means on said crown ends of said cap members adapted to be engaged in opposition to said spring means for transmitting movement of the false cap member to the main cap member.
