Abstract
Abstract A safety closure for a container is provided with pivoted locking means rotatably mounted in and passing through the side wall of the closure to contact the neck of the container and having means slide through the neck threads in screwing on the closure. In fully tightening the closure on the neck, a portion of the locking means contacts abutment means on the neck of the container causing rotation of the locking means to fully locking position. After the closure is screwed on, in an attempted returning removal of the closure, an inward contacting portion of the locking means is placed in a position transverse of the neck threads, thereby preventing closure removal. The safety closure is thusly secured against opening by young children.

185 words
A container and safety closure combination, comprising: a closure comprising a vertically disposed side wall being formed with a transverse hole therethrough, and internal side wall threads and a top horizontally disposed to said side wall; a container integrally formed with a neck portion, said neck portion formed with external threads for engaging said closure wall threads; pivoted locking means comprising a cylindrical body and two ends thereof, transversely disposed to and extending through and rotatably housed within said hole of said side wall, said pivoted locking means having one end thereof inward of said side wall and the other end outward of said side wall, said locking means, said outward end thereof integrally formed with an extension thereon to rotate said locking means, said inward end thereof being integrally formed with means to slidably engage said neck threads when said locking means disposed in a first rotary position and means to blockingly engage at least a part of said neck threads when said extension rotates said locking means to rotate said locking means to a second rotary position other than said first rotary positions.
Claim 3
Dependent Claim
37 words
The combination of claim 1, said extension comprising a wing portion integrally formed with the outward end of said pivoted locking means, said wing portion perpendicularly disposed to said cylindrical body portion and extending radially away therefrom.
Claim 4
Dependent Claim
61 words
The combination of claim 1, said means to slidably engage said neck threads comprising an oblongated member integrally formed with the inward end of said cylindrical body of said pivoted locking means and raised up from said end and diagonally disposed on and to said cylindrical body, said oblongated member an oblongated surface thereof being slidably engageable with said neck threads.
Claim 5
Dependent Claim
30 words
The combination of claim 3, said oblongated member being formed with a groove transversely disposed thereto, whereby the lower end of said neck threads is blockingly engageable within said groove.
Claim 6
Dependent Claim
40 words
The combination of claim 2, said container further comprising means to actuate said wing portion so as to rotate said pivoted locking means from said first position to said second position as said closure is screw tightened on said container.
Claim 7
Dependent Claim
94 words
The combination of claim 5, said means to actuate said wing portion means comprising a raised member integrally formed with said container and said extension comprising a wing portion integrally formed with the outward end of said pivoted locking means, said wing portion perpendicularly disposed to said cylindrical body portion and extending radially away therefrom; whereby upon screw tightening said closure on said container said wing portion contacts said actuating means and is arcuately, upwardly displaced therefrom, in turn causing said pivoted locking means to rotate from said first position to said second position.
Claim 8
Dependent Claim
58 words
The combination of claim 4, said neck further comprising a member raised from the surface thereof and located below the end of the lowest neck thread, one surface of said member in a blockiNg relation with an opposed oblongated surface of said oblongated member of said pivot member when said pivoted locking means is in said second position.
Claim 9
Dependent Claim
22 words
The combination of claim 1, wherein said closure comprises and outwardly protruding annular portion surrounding and outwardly extending from said transverse hole.
Claim 10
Dependent Claim
48 words
The combination of claim 8, said transverse hole of said side wall, the transverse surface thereof having a radially extending groove therein and said cylindrical body portion of said pivoted locking means is formed with at least one radially extending lock button being slidably engageable within said groove.
Claim 11
Dependent Claim
38 words
The combination of claim 8, wherein said protruding annular portion is formed with a stop member thereon so as to blockingly engage said extension so as to limit the degree of rotational movement of said pivoted locking means.
Claim 12
Dependent Claim
25 words
The combination of claim 9, wherein said cylindrical body portion of said pivoted locking means is formed with two diagonally disposed, radially extending lock buttons.
Claim 13
Dependent Claim
54 words
The combination of claim 5, said inward end of said pivoted locking means being integrally formed with a semi-cylindrical member raised up inwardly from the cylindrical body portion of said pivoted locking means, said semi-cylindrical member being slidably engageable with said neck threads when said pivoted locking means is disposed in first rotary position.
Claim 14
Dependent Claim
43 words
The combination of claim 12, wherein a portion of the lowest neck thread is formed with a downwardly disposed semi-cylindrical groove therein, said semi-cylindrical raised portion of said pivoted locking means being slidably rotatably engageable within said semi-cylindrical groove of said neck thread.
Claim 15
Dependent Claim
