Abstract
Essentially "U" shaped endless elastic loops, with the opening facing inwardly, removably hold first foil covers over access openings of flanged containers. The foil is placed over the container opening and flange formed around the opening. The elastic loop is stretched to encompass the foil cover and flange and then released to secure the foil cover over the access opening. Clamping strips can be provided with the elastic loops to hold second foil covers onto the elastic loops and over the container openings. The clamping strips are provided with protrusions or recesses that match recesses or protrusions on the upper surfaces of the elastic loop to clamp foils between them and over the access openings.
Claims20
A flexible closure holder including:
- an endless elastic loop formed by a base with an upper leg and a lower leg extending from said base:
- said endless elastic loop upper leg and said endless elastic loop lower leg being parallel to each other and forming an inwardly opening elongated recess that has a depth essentially the width of said elastic loop upper leg and said elastic loop lower leg with said recess having a height between said elastic loop upper leg and said elastic loop lower leg being less than the thickness of said elastic loop upper leg and less than the thickness of said elastic loop lower leg along its entire length, so as to be capable of pressing on the upper and lower surface of a horizontally outwardly extending flange of a container while its base presses against the end of said flange on said container;
- said endless elastic loop being stretchable by more than 2% of its unstretched length with the ability to return to its unstretched length, so as to be able to elastically deform and hold in place a flexible closure over said container.
A detachable elastic loop retaining means in combination with a container for securing a flexible foil over said container wherein:
- said container has an open end with a flange extending outwardly around the periphery of said container open end;
- said elastic loop has an upper leg and a lower leg extending inwardly parallel to each other from a base forming an elongated recess facing inwardly;
- said recess having a height between said elastic loop upper leg and said elastic loop lower leg being less than the thickness of said elastic loop upper leg and less than the thickness of said elastic loop lower leg along its entire length, so as to be capable of pressing on the upper and lower surface of a horizontally outwardly extending flange of said container while its base presses against the end of said flange on said container;
- said elastic loop is endless with said base peripheral length being essentially the same as that of said container flange outer peripheral length;
- said elastic loop has enough elasticity to be stretched over said container flange and to return to its unstretched length so as to be able to secure and hold said flexible foil in place over said container open end.
