QHA 7776s BY MPM A TTORNEYJ Patented Oct. 13, 1931 UNITED/ STATES PATENT OFFICE CHARLES H. AMES, OF WORCESTER, MASSACHUSETTS MEANS r03. SEALING rAcmeEs Application filed March 7, 1929. Serial No. 345,075.

spaced longitudinal edgeportions thereof treated with a suitable gum or adhesive and 15 having a central non-adhesive portion between said adhesive edge ortions.

The non-adhesive mi dle portion constitutes a tearing or severing strip which may be readily removed, thus freein the adjacent 2 edges of the wrapper or package. The removal of the tearmg strip ma be facilitated by providing one or more tabs by which it may be more easily grasped, and also by scoring or perforating thesealing strip lon itudinally between the adhesive and non-a hesive portions I My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particu- 80 larly pointed out in the appended claims.

A preferred form of the invention and certain modifications and developments thereof are shown in the drawings in which Fig. 1 is a'plan view of a portion ofa pack-. age or wrapping having my improved sealing strip applied thereto;

- Fig. 2 is a transverse sectional view, taken along the line2-2 in Fig. 1;

Fig. 3 is a plan view of a portion of a sealing strip provided with longitudinal perfora- Fig. 7 is a sectional view, taken along the line 7- 7 in Fig. 6.

Referring particularly to Figs. 1 and 2, I have shown my invention applied to a contamer or wrapping having an outer portion 8 overlapping an under portion 9. The edge of'the under portion is indicated at 10 and obviously may be extended any distance within the outer portion 8.

My improved sealing strip S is applied along the edge of the overlapping portion 8 and comprises a strip of suitable material provided with adhesively treated or gummed portions 11 along each longitudinal edge thereof.

The middle portion 14 of the strip S is not treated with adhesive and when in use does not attach itself to the wrapper or container to which the stri is applied.

It will be evi ent that a sealing strip as above described, when applied to a wrapper or container, will firmly secure the overlaping or adjacent parts together and will efectlvely seal the package, while at the same time the wrapper or package may be readily opened by removing the middle portion 14.

This may be readily done, due to the fact that the middle portion is not treated with adhesive and thus constitutes an effective tearing strip. The removal of this strip 14 is facilitated by providing an extension 15 at one or both ends of the portion 14, this extension forming a tab by which the portion 14 may be readily grasped and torn away from the adhesive portions 11. After this is done, the overlapping portion 8 of the wrapper is entirely free and the package may be opened or unfolded.

Certain modifications of my invention are shown in Figs. 3 to 7, to which reference will now be made.

In'Fig. 3 I have indicated the provision of longitudinal lines of perforations 16 between the adhesive and non-adhesive portions, which facilitate the removal of the tearing strip and assure the severing thereof along the desired lines.

In Fig. 4 I have indicated the attainment of similar results by scoring the strip longitudinally, as indicated at 17 The form shown in' Fig. 5 is "particularly designed for production in continuous strips or rolls and in this form adjacent tabs 18, separated by an opening 19, are provided.

5 A strip thus constructed may be cut or torn from a continuous roll and the tearing strip may be removed by starting at the middle of its length and tearing toward each end thereof.

In Fig. 6 I have indicated a form of my invention in which a separate strip 21 is secured to the under side of a sealing strip S, the strip 21 bein preferably gummed to the strip S along the middle portion thereof, 5 but substantially separated from the adhesive areas 11. The strip 21 may be extended to i provide a tab and the strip may be readily 'severed as previously described( While I have shown my improved sealing means as applied to a package having an overlapping covering, it will be evident that the invention is equally applicable to fibre board boxes and other containers in which the edges to be secured abut rather than overlap.

Having thus described my invention and the advantages thereof, I do'not wish t be limited to the details herein disclosed, otherwise than as set forth in the claims, but what so I claim-is:

1. A sealed package comprising a container 1 having an edge portion thereof adjacent some other-portion of said container, and a separate sealing means consisting of a sheet having two integral, longitudinally extended edge portions secured to said two adjacent portions of said container respectively, and a middle longitudinal portion integral with said edge portions said middleportion of said sealing means eing free from said container but overlying the extreme outer edge of one portion thereof, said free portion of the sealing means having an integral tab by means of which it may be readily grasped and severed from said attached portions of the sealing means.

2. As an articleof manufacture, a sealing strip consisting of a sheet having integral,

longitudinally extended edge portions treat ed with adhesive, and having its longitudinal middle portion free from adhesive, said middle portion being integral with-said edge portions, and provided with an integral tab by means of which said middle portion may be conveniently detached from said edge portions.

nally extended between said middle portion and said edge portions.

4. In a sealing strip, a plurality of body.,.

elements each comprising a single sheet hav- 7 ing an intermediate ortion and plural edge portions integral with said intermediate-portion, one of said edge portions being provided with an adhesive area ada ted when moistened to engage adjacent t e line of juncture, the overlapping surface of a package wrapper, and the other edge portion bein provided with an adhesive area and adapte to engagethe overl pping surface thereof, the said intermediate portion being non-adhesive and having means integral therewith, to which force may be applied for tearin away said intermediate portion from sale edge portions, said body elements being partially separated from each other by cutouts.

In testimony whereof I have hereunto aflixed my signature.

CHARLES H. AMES.

3. As an article of manufacture, a sealing strip consisting of a sheet having integral,

longitudinally extended edge portions treated with adhesive, and having its longitudinal middle portion free from adhesive, said middle portion, bein integral with said edge portions, and exten edat one end to provide an integral tab by means of which said middle portion may be conveniently detached from inc
