Abstract

Abstract A plastic self-reclosing safety cap is described which is made of two molded pieces, one fixed to the bottle or container which it closes, and the other piece nested over the first so as to normally close an aperture, but which can be opened by first pulling and then twisting the outer piece to align its aperture with the aperture in the first cap, against the resilience of an integral elastic annular band which restores the normal closed condition when the opening force is released.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 206 words
A. A dispensing container having a safety closure, b. said container comprising a fixed portion having a first top wall portion and a first side wall portion, c. said top wall portion having an off-center first dispensing aperture, d. an outer cap member having a movable section slidably covering at least a part of said neck portion and having a second side wall portion and a second top wall portion extending across said first top wall portion, and having a second dispensing aperture aligned with said first dispensing aperture in one radial position of said outer cap member, e. said second top wall portion covering said first aperture in another radial position of said outer cap member, f. an annular elastic band, having a lower and an upper edge, extending circumferentially around said neck portion and fixed at its lower edge with respect to said fixed portion and at its upper edge to the bottom edge of said movable member to normally retain said outer cap member in said other radial position wherein said first aperture is covered, g. said elastic band being circumferentially elastically distortable by manual force applied to said outer cap to permit said second aperture to be aligned with said first aperture.
Claim 2
Dependent Claim 206 words
A. A dispensing container having a safety closure, b. said container comprising a fixed portion having a first top wall portion and a first side wall portion, c. said top wall portion having an off-center first dispensing aperture, d. an outer cap member having a movable section slidably covering at least a part of said neck portion and having a second side wall portion and a second top wall portion extending across said first top wall portion, and having a second dispensing aperture aligned with said first dispensing aperture in one radial position of said outer cap member, e. said second top wall portion covering said first aperture in another radial position of said outer cap member, f. an annular elastic band, having a lower and an upper edge, extending circumferentially around said neck portion and fixed at its lower edge with respect to said fixed portion and at its upper edge to the bottom edge of said movable member to normally retain said outer cap member in said other radial position wherein said first aperture is covered, g. said elastic band being circumferentially elastically distortable by manual force applied to said outer cap to permit said second aperture to be aligned with said first aperture.
Claim 3
Dependent Claim 62 words
The invention according to claim 1, h. and a small plug integral with said second top wall and extending downwardly therefrom into said first aperture when said outer cap is in said other radial position, to prevent radial rotation of said outer cap until said outer cap is first pulled away axially from said fixed portion sufficiently to clear said small plug.
Claim 4
Dependent Claim 73 words
The invention according to claim 2, i. said container having a pouring aperture, j. and said outer cap and said fixed portion being of at least semi-rigid plastic material, the bottom of said neck portion being fixed to said neck container around said pouring aperture, k. and an annular rigid plastic rign surrounding said neck portion and fixed thereto, the bottom of said elastic band being fixed to a portion of said ring.
Claim 5
Dependent Claim 20 words
The invention according to claim 2, i. said fixed portion being integral with said container and of the same material.
Claim 6
Dependent Claim 33 words
The invention according to claim 2, and an annular rigid plastic ring surrounding said fixed portion and fixed thereto, the bottom of said elastic band being fixed to a portion of said ring.
Claim 7
Dependent Claim 75 words
The invention according to claim 5, i. at least said outer cap member being of rigid plastic material, and including said movable section and a lower section connected by said elastic band, said lower section being said annular plastic ring, j. and a thin frangible band of said rigid plastic material between said upper and said lower sections and serving to hold them together prior to application of said elastic band to the outer cap.
Claim 8
Dependent Claim 49 words
The invention according to claim 1, h. and mutually interlocking elements on the inner side of said second side wall portion and on the outer side of said first wall portion for retaining said outer cap member against rotation when lateral pressure is applied between said two wall portions.
Claim 9
Dependent Claim 18 words
The invention according to claim 7, i. said mutually interlocking elements being axially extending ridges having tapered sides.
