2 Claims.

This invention relates to new and useful improvements in covers for bottles, jars, containers, and the like.

The object of this invention is to provide handy, quick and easily applied covers for many types of containers, so that covers of different dimensions may conveniently be kept on hand for almost every container, for instance, in a kitchen.

According to a feature of this invention, the covers are kept attached to one another, and are preferably formed into a roll. As a cover is needed it is unwound from the roll and torn free along a weakened line. e. g., perforations provided for that purpose. Several rolls of varyin lengths and widths can be conveniently placed in a rack. Preferably the covers are made of cellulose acetate partly coated on one side with pressure-sensitive adhesive substance.

These and other features of the invention will more clearly appear from the appended claims and the following detailed description of a preferred embodiment, in which:

Fig. 1 is a top plan view of a roll partly unwound;

Fig. 2 is a top plan view of three different sized I covers detached from their respective rolls;

Fig. 3 is a perspective view of three rolls in place on a rack;

Fig. 4 is a view of a cover on a small round container; and

Fig. 5 is a view of a cover on a rectangular container.

A roll 1 comprises a long web of cellulose acetate material, preferably transparent, which has transverse perforations or score lines 2 at predetermined intervals across its entire width. The length of an individual cover 3 is delimited by the perforations 2 and its width by the edges of roll I. The cover 3 is detached from the rest of the roll I merely by unwinding and tearing along the perforations 2.

A pressure-sensitive adhesive coating 4 is applied to the four margins on one side of cover 3. In the preferred embodiment of this invention the coating 4 is applied in a band close to the edges of cover 3, leaving uncoated a narrow strip 5 along the edges to facilitate the forming of pleats along the edges as shown in Figs. 4 and 5, and insuring that the cover will tightly fit the opening of the container and conform to the mouth thereof. However, the coating 4 may extend to the edges of the cover 3.

The coatings 4 will cause superimposed layers of the roll to stick together without marring the surface when the roll is unwound. The individual container covers 3 can be detached one-byone, leaving the rest of the roll intact, and individually applied to a container merely by stretching the cover 3 over the container openins and pressing the margins to the sides or the container wall, as shown in Fig. 4. The coating 4 will cling to the container, but can be detached therefrom without employing special tools, and without destroying the cover or smudging the container.

Three detached covers 3 of different sizes are shown at a, b and c in Fig. 2. The three rolls from which a, b and 0 were taken are shown in Fig. 3 at 6, 1 and 8 mounted in a rack 9. The rack 9 may be of any suitable material and shaped to accommodate different sized rolls which are rotatably supported therein. A supply of covers a, b and 0 can thus be kept readily accessible in roll form for application to different sized containers, e. g. like the ones shown in Figs. 4 and 5. As indicated in these figures, the cover 3 will be pulled taut on the containers, and the edges or margins of the cover pleated so as to conform to the contour of the container. The edges will not be sticky and will readily fold as well as furnish a grip for quick and clean removal of a cover from a container.

While the coating 4 is shown as applied in a continuous band, it may be interrupted.

What is claimed is:

1. A roll of container covers comprising a continuous web of cellulose acetate having transverse perforations along which it may be readily torn, and a pressure-sensitive adhesive coating applied in a continuous narrow band parallel with the four edges of each cover but spaced therefrom.

2. A roll of container covers comprising a continuous web of cellulose acetate having transverse perforations along which it may be readily torn into individual covers, a pressure sensitive adhesive coating applied in narrow bands, each parallel with at least one of the four edges of each cover, and a narrow uncoated strip of the cover hgng between each band and the nearest parallel e ge.
