ES249888U - A neck and neck set for children (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

A child safety collar and plug assembly applicable to the mouth of a package of hygiene or cleaning products, such that in the normal closing position of said plug, it can be rotated freely in the neck of the container, but can not be extracted from it, although a considerable extraction force is applied, characterized in that the neck of the container has a first cylindrical part, followed upwards by a frustoconical surface of a smaller diameter greater than that of the cylindrical surface above, so that an annular shoulder is formed between them, the cylindrical surface having in diametrically opposite parts two triangular projections, the outer faces of which are on a cylindrical surface concentric with the former and forming two upper ramp surfaces, and because the stopper has, on the one hand, in diametrically opposed points, separate ejection projections directed towards dent ro, located near the lower edge of the stopper and at the same height as the above-mentioned ramp projections, when the stopper is normally applied in the container, in which position the distance between the inner faces of said facing ejection projections is slightly greater than the distance between the cylindrical outer surfaces of said ramp projections, so that the turning of the plug in its normal state of application, said elements do not interfere mutually, passing the ejection projections of the cap outside the outer surfaces of the projections mentioned ramp and, on the other hand, in two diametrically opposite areas of the cap and centered on ends of a diameter perpendicular to the diameter determined by the ejection projections, retaining projections are provided, in the normally applied position of the cap in the container, they are applied under the annular shoulder of the neck thereof, so that they retain in position firmly the cap on the neck of the container, while allowing freely rotate it, being such the arrangement that by pressing inward the plug in diametrically opposite points corresponding to the projections of the same and by rotating said cap in a clockwise direction said projections slide along the ramps of the neck of the container, while the retaining projections are separated from the annular shoulder of said neck, whereby the cap is displaced by the camming action of said ramps axially outward, separating from the neck of the cap.
