Abstract
A plug and wickholder is configured to be reliably sealed to the neck of a bottle which contains a liquid to be atomized and to a cap which seals the bottle during storage. The plug and wickholder includes a first generally tubular wall which contains a wick and which fits tightly into a cap sealing wall, and it further includes a generally cylindrical sealing wall which fits tightly into a bottle neck. A second generally vertical tubular wall is interposed between the first generally tubular wall and the generally cylindrical sealing wall.
Claims22
A plug and wickholder comprising a unitary molded plastic piece which includes:
- a first, generally vertical tubular wall for containing a wick
- a second, generally vertical tubular wall extending around and concentric with said first tubular wall, said first and second tubular walls being connected to each other near their lower ends thereof and tapering slightly away from each other in a direction toward their upper ends;
- a generally horizontal upper wall which can be fitted over the top of a bottle neck, said upper wall being integral with and extending radially outwardly from said second tubular wall near its upper end;
- a circumferential skirt extending down from the outer edge of said radially extending upper wall, said skirt being formed on its internal surface near the bottom edge thereof with at least one latch element to hold said skirt to the neck of a bottle;
- and
- a generally cylindrical sealing wall extending down from said upper wall between said skirt and said second tubular wall for fitting inside of and becoming sealed to the inside surface of a bottle neck when said at least one latch element holds said skirt to said bottle neck, said cylindrical wall being free of other structure at its lower edge.
3 more elements
A combination comprising:
- a plug and wickholder comprising a unitary molded plastic piece which includes:
- a first, generally vertical tubular wall for containing a wick
- a second, generally vertical tubular wall extending around and parallel to said first tubular wall, said first and second tubular walls being connected to each other near their lower ends thereof;
- a generally horizontal upper wall which can be fitted over the top of a bottle neck, said upper wall being integral with and extending radially outwardly from said second tubular wall near its upper end;
- a circumferential skirt extending down from the outer edge of said radially extending upper wall, said skirt being formed on its internal surface near the bottom edge thereof with at least one latch element to hold said skirt to the neck of a bottle;
- and
- a generally cylindrical sealing wall extending down from said upper wall between said skirt and said second tubular wall for fitting inside of and becoming sealed to the inside surface of a bottle neck when said at least one latch element holds said skirt to said bottle neck, said cylindrical wall being free of other structure at its lower edge;
- and
- a sealing cap removably connected to said plug and wickholder, said sealing cap having a tubular cap sealing wall extending down from a top wall and sealingly fitted to the outer surface of said first generally vertical tubular wall.

- a generally horizontal upper wall which can be fitted over the top of a bottle neck, said upper wall being integral with and extending radially outwardly from said second tubular wall near its upper end;
- a circumferential skirt extending down from the outer edge of said radially extending upper wall, said skirt being formed on its internal surface near the bottom edge thereof with at least one latch element to hold said skirt to the neck of a bottle, and
- a generally cylindrical sealing wall extending down from said upper wall between said skirt and said second tubular wall for fitting inside of and becoming sealed to the inside surface of a bottle neck when said at least one latch element holds said skirt to said bottle neck, said cylindrical wall being free of other structure at its lower edge;
- and
- a bottle having a neck which fits between said circumferential skirt and said generally cylindrical sealing wall.
