Abstract
In a cap and container closure, the cap is integrally formed with a trigger sprayer housing and the cap and container have a bayonet-type closure that attaches the cap to the container by pressing the cap downwardly on the container without turning, or by no more than a quarter turn of the cap relative to the container, and the cap also has upper and lower lugs that engage against the top and bottom surfaces of ridges on the container neck to hold the cap securely on the container neck and prevent any rocking movement of the cap on the container.

A closure for a cap and container comprising:
- a cap having a center axis and a cylindrical interior surface with a lower lug projecting radially inwardly from the interior surface and an upper lug projecting radially inwardly from the interior surface, the upper lug being axially spaced from the lower lug;
- a container having an opening with a center axis and a cylindrical neck extending around the opening, a ridge extends radially outwardly from the container neck and the ridge is positioned on the neck where the lower lug will engage against a bottom of the ridge and the upper lug will engage against a top of the ridge when the cap is attached to the neck.
A closure for attaching a cap to a container neck surrounding an opening of the container, the container neck having a ridge projecting radially outwardly from the neck, the ridge having a leading end and a trailing end with an arcuate length therebetween, the closure comprising:
- a cap having a center axis and a cylindrical interior surface with a lower lug projecting radially inwardly from the interior surface and an upper lug projecting radially inwardly from the interior surface with an axial spacing between the lower lug and upper lug dimensioned to receive the container neck ridge therebetween when attaching the cap to the container neck.
A closure for a container for receiving a cap thereon, the cap having a cylindrical interior surface with a lower lug projecting radially inwardly from the interior surface and an upper lug projecting radially inwardly from the interior surface with a spacing between the upper lug and the lower lug, the closure comprising:
- a container having an opening with a center axis and a neck surrounding the opening, a plurality of arcuate ridges project radially outwardly from the neck and are arranged in a circle around the neck with a spacing between adjacent ridges, and each of the ridges has an axial width dimensioned to enable at least one of the ridges to pass between the lower lug and the upper lug of the cap when attaching the container neck to the cap.
