Anderson, West (Ialdwell, NJL, assignor to Scandia Packaging Machinery Company, North Aisling ton, N..l., a corporation of New lersey Griginal application .lan. E3, 1961, Ser. No. 82,422.

2 Qiairns. (U1. 229-87) This invention relates to wrapper sheets and to packages wrapped therewith, and is a division of application Serial No. 82,422, filed January 13, 1961, now abandoned.
When wrapped packages are sold, as, for instance, by wholesalers, it often becomes necessary or desirable for retailers to break open the package so that the prices can be marked on the packaged articles. With the ordinary package the wrapping, after being broken, often becomes unusable.
This invention has for its salient object to provide a package so formed that it can be readily broken open for price marking or any other desired purpose and can be thereafter rescaled.
Another object of the invention is to provide a package having perforations across one face and registering perforations at the ends of the package so that the package can be readily broken open.
Another object of the invention is to provide a wrapper sheet so perforated that one face of the wrapped package formed with the sheet will have a line of perforations across the width of the face and the two ends of the package will have lines of perforations registering with the perforations on the face.
Further objects of the invention will appear from the following specification taken in connection with the drawings which form a part of this application, and in which PEG. 1 is a perspective elevational view of a wrapper sheet;
FIG. 2 is a diagrammatic view showing the package and the wrapper sheet in position to be pushed by the package into folding and wrapping mechanism;
FIG. 3 is a collective elevational view looking at the end of the package and showing three stages of the folded wrapper;
FIG. 4 is a collective view of the end of the package looking in the direction of the arrow indicated as 4 in the bottom figure of FIG. 3, FIG. 4 showing two views of the package end in successive stages of the folding wrapper;
FIG. 5 is a perspective view of the wrapped package;
P16. 6 is a perspective view showing the wrapped package with the perforations thereon; and
FiG. 7 is a perspective view showing the package broken open along the perforations.
In the embodiment of the invention illustrated in the drawings, there is shown a Wrapper sheet S having a line of perforations across the width of the sheet, as shown at A, and having perforations B and B at the edges of the sheet spaced from the perforations A.
These perforations are so formed that when the wrapper is folded into a package the perforations indicated at A will extend across one face of the package and along the two ends and the perforations B and B will extend across the ends in registration with the ends of the line of perforations shown at A in PEG. 6. Thus, when the package is broken open, as shown in FIG. 7, the perforations will permit the two halves of the package to be broken apart along the lines A, B and B. After the package has been so broken access can be had to the contents which can be price-marked without removing them from the package. These two halves can then be swung together along the hinge formed by the back face and can be secured by "ice taping them together and the packages can be stored for future use.
The Wrapper sheet passes downwardly until it is positioned opposite a channel 39, in which position it is disposed in the path of articles 36 fed by a plunger into the channel 39 which leads to folding mechanism of the usual well-known construction and which is not illustrated.
The wrapper is folded by the usual well-known folding mechanism, but the folds formed therein are shown particularly in FIGS. 3, 4 and 5. When the articles 36 are pushed into the channel 39, the wrapper sheet is folded across the side on of the package and across the upper and lower faces 61 and 62. This leaves the ends of the sheet extending beyond the end 64 of the package. This is shown in the top figure in MG. 3. In this stage of the wrapping, the wrapper sheet extends beyond the ends of the package.
In the next stage of the wrapping, the projecting ends at the edge 60 of the package are tucked against the ends of the package, as shown in the middle figure in FIG. 3. Thereafter, the wrapper is folded against the ends, as shown in the bottom figure in FIG. 3.
in the final stage of the wrapping, tucks are formed at the opposite side of the package, as shown in FIG. 5, and the upper and lower flaps are folded and secured by suitable sealing means.
When the package has been formed in the manner described, it will be seen that the line of perforations A extends across the top of the package, viewing FIGS. 6 and 5, and also across portions of the ends of the package, and the perforations B, B extend across the remaining portions of the ends in registration with the extended ends of the line of perforations A. A slit 43 is formed at the central part of perforations A.
Thus, the package can be broken or opened in the manner shown in FIG. 7 to permit access to the contents thereof. Thereafter, the package can be again closed and sealed with suitable sealing tape.
Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
What I claim is:
1. A wrapper for forming a resealable package comprising a single rectangular sheet element including parallel upper and lower margins normal to longitudinal side edges, a first line of perforations spaced below the upper margin of said sheet element and parallel thereto, said first line of perforations extending across the entire width of said sheet between said longitudinal side edges, said sheet element including two collinear lines of perforations spaced from and parallel to said lower margin and said first line perforations, said two collinear lines of perforations terminating short of each other.
2. A wrapper sheet as claimed in claim 1 in which said first line of perforations includes an intermediate slit.
