UNITED STATES PATENT OFFICE.

CHARLES H. MACDONALD, OF MONTCLAIB, NEW JERSEY. AS'SIGNOR, BY MESNE AS- SIGNMENTS, TO IVERS-LEE COMPANY, OF NEWARK, NEW JERSEY, A CORPORATION OF DELAWARE.

PACKAGE.

Application filed June 7, 1919, Serial No. 302,548. Renewed October 30, 1924.

To all whom it may concern Be it known that I, CHARLES H. MAC- DONALD, a subject of Kin dom of Great Britain, residing in Montclair, in the county of Essex and State of New Jersey, have invented an Improvement in Packages, of

which the following is a specification.

The present invention relates to an 1mprovement in packages, more particularly of the kind adapted to contain products readily segregated as units, such as medicinal preparations or other chemical or edible a-rtlcles in tablet or similar form, small articles of, hardware, buttons and various other relatively small articles.

One of the principal objects of this invention is to provide a package which will afford an effective covering for articles of the character referred to and others, not only to protect such articles from dust, dirt and the like, but also, where the articles are soluble, to exclude moisture from contact therewith so that they may be transported or carried in stock without deterioration. I

lhe invention also, so far as it relates to a process or method, is intended to provide a sequence of operations in accordance with which a suitable package of the character described may readily be formed.

One form of package embodying my invention is illustrated in the drawings accompanying the present specification, said drawing also serving to illustrate a typical application of my improved method of making one form of package embodying my invention. In the drawings,

Figure 1 is a plan view of a web of material with spaced articles in position thereon,

Figure 2, a. plan view of the same or a similar web with the marginal portions folded to inclose articles and with the portions between the articles stifi'ened and pressed into adhering contact.

Figures 3 and 4. are longitudinal and transverse vertical sections respectively of a portion of the package illustrated in Fig ure'2.

In practicing the method forming a part pf the present invention, a strip 1 of flexible material, preferably paper, having a coating of paraflin on at least one side and, with the articles to be packaged arranged thereon in spaced relation may be folded lon itudi nally to form a tubular container wit continuous closed edges adapted to incloso articles 2, the folding being accomplished in such a manner that the interior surface will be paraffined and the inclosed articles arranged in spaced relation. Pressure may then be applied to the tubular container between the spaced articles in such amanner as to form adhering or sealing stiffened portions 3. One convenient way to accomplish this sealing and stiffening is to crimp the tube transversely, a suitable type of crimpmg being shown in Figure 2 of the drawing.

In pursuing the method hereinabove described, a package is produced in which spaced articles are inclosed in a container having. adhering or interlocking stiflened portions 3, formed either by crimping or otherwise pressing opposed interior portions into intimate adhering contact, between each two adjacent articles, said stiifened portions serving not only to space the articles but also when the strip is bent transversely with spacing portions interposed flatly between articles carrying compartments, to protect the articles from breakage. In manufacture this stiffening also enforces bending of the strip at unstiffened portions thereof, or across the compartments otherwise across the'stiffened spacing pon 'tion during the detaching of a unit or units from the package to prevent unsealing or exposure of the next succeeding unit.

in using packages embodying my inven- U011, or made in accordance with the method hereinabove set forth, the consumer or user may detach a single article simply by tear ing or cutting the material adjacent to said article, and without exposing the article next in succession. This form of package for many articles presents advantages in use [over packages heretofore commonly used, not

only in the additional protection from dust and moisture already referred to, but also in the facility with whlch such packages may be made, the, inofl'ensive character of the materials of the package, and the compactness and durability thereof, all of which are dethat the strip may be gripped manually or articles arranged thereon to form a tubular sirable qualities in packages intended for use with articles of. various kinds. I claim as mi invention: 1. The met 0d of packaging articles which includes coating a strip of flexible material with a plastic material arranging articles to be packaged on said strip in spaced relation, folding said strip longitudinally with a coated surface inside to enclose cles in spaced relation in a strip of paper having a coating of parafiin by folding over the longitudinal edges of said strip with the container, the coated surface of the strip forming the interior surface of the container, and pressing opposed interior surname to this specification this 3r faces of said container into adhering contact to form article isolating portions, between enclosed articles.

3. A package consisting of a strip of flexible material havin a coating of paraliin on one side and wit% its longitudinal edges folded toward and overlapping each other to form an article carryin tube with a paraffin coated interior sur ace, said tube being provided at spaced intervals across its entire width with tube deforming crimp-- ings extending lengthwise of the tube and through its walls to securely hold spaced portions of said walls in effective tube closmg and sealing contact and to impart relative rigidity tosaid tube closing portions.

In testimony whereof, I have si ed my day of June, 1919.

CHARLES H. MACDONALD.
