PACKAGE AND METHOD OF PACKING Original Filed April 20, 1939 INVENTOR C424 JJCH/V/D Patented Dec. 11, 1945 Carl J. Schmidt, New York, N. Y., assignor to Julius Schmid, Inc., New York, N. Y., a corporation of New York Original application April 20, 1939, Serial No.

269,026. Divided, and this 1943, Serial No. 485,566

3 Claims.

This invention relates to packages and the method of packing and is a division of my copending application Serial No. 269,026 filed April 20, 1939, now Patent No. 2,321,254.

One of the objects of the present invention is the production of a simple andeificient package for rolled tubular goods and the like.

A further object of this invention is the provision of a novel method of packing such goods, wherein the articles are compressed transversely whereby to reduce the diameter to substantially the diameter of a wrapper, then inserting the same in the wrapper and allowing the article to expand into frictional engagement with the walls of the wrapper and be confined thereby as will be more fully explained presently.

Other objects and advantages of the present invention will appear throughout the following specification and claims.

In the drawing:

Figure 1 is a top plan view of the package showing the manner of inserting the rubber goods therein, a portion of the wrapper being broken away;

Figu e 2 is an edge elevational view of the package showing the goods in position;

Figure 3 is an edge elevation of the wrapper, a certain portion being broken away and illustrating the position of the goods just before the rubher article engages the lip-portion of the wrap- Figure 4 is a view similar to Figure 3, showing the article contacting the extending lip portion;

Figure 5 is a view somewhat similar to Figure 4, showing the rubber article partly inserted I in the wrapper;

Figure 6 is a perspective view of the wrapper;

Figure 7 is a plan view of the article before being compressed for packing.

By referring to the drawing, it will be seen that In designates the wrapper which is preferably formed of flexible paper to provide a, relatively fiat tube-like structure. The ends of the wrapper are out upon either side thereof to provide notches H to define upper lips l2 and lower extension lips I3. As shown in the drawing, the wrapper I0 is preferably provided with an uper lip I2 and a lower extension lip [3 at each end of the wrapper. The article to be inserted, indicated by the numeral I4, is squeezed to gether, as shown in Figure 1 in dotted lines, by means of the fingers of the operator, or by any other suitable or desired means to provide a rounded insertable end indicated in dotted lines by the numberal IS in Figure 1. The wrapper I0 application May 1,

and the article 14 is moved across the outer end of the upper lip l2, as shown in Figure 3, and rests upon the upper face of the lower. extension lip I3, in the manner as shown in Figure 4, which lip I3, should pressure be exerted thereon, will flex downwardly in the manner shown in Figure 4, thereby enlarging the opening at the end of the wrapper l0 and facilitating the insertion of the article 14 into the wrapper ID by moving the article in the direction of the arrows shown in Figures 4 and 5. The article l4 may then be moved longitudinally of the wrapper 10 until the article is completely encased within the wrapper and moved to the position shown in Figure 1.

It has been found by actual experiment, that it is highly important to provide a wrapper or container for an article such as is illustrated, so that the article may be easily inserted within the wrapper or package without fear of crimping the ends or distorting or marring the entrance edge of the wrapper. been illustrated has resulted in a great saving in the cost involved in placing the article within the wrapper due to the fact that the process of inserting the article into the wrapper has been greatly speeded up, and the fact that the lower extension lip i3 provides a guide and rest for contacting the end of the article greatly facilitates the insertion of the article. The fact that the upper and lower lips l2 and I3 are of different lengths is also a very important item in that the movement necessary to insert the article into the wrapper will permit the end of the article to brush against the extension end of the upper lip l2 and come to rest upon the extension lip I3 and then allow the article to be moved inwardly, the extension lip l3 providing a guide for the insertion of the article into the wrapper.

It will be noted from Figure 1, that when the pressure of the fingers of the operator is released, after the article has been inserted to the full line position of Figure l, the article will expand and engage the walls of the longitudinally sealed tubular wrapper and be confined thereby and frictionally held in the wrapper.

It should be understood that certain detail changes in the structure may be employed without departing from the spirit of the invention, so

The particular structure which has long as such changes fall within the scope of the appended claims.

WhatIclaim is:

1. The method of packing a tenacious thin film article of substantially cup-shape, which comprises first the step of rolling the article upon itself in successive peripheral folds from itsppen end to its closed end to form a circular ring of high resilient resistance to radial distortion and of spiral rim section webbed by the closed end "01 the cup. second, the step of radially distorting. the

ring into an elongated closed loop having slightly laterally spaced substantiallyparallel sides constituted by portions of the rim, and third, the step of encasing the article in a shield of less tenacity and resilience around the article entirely protecting and holding it in said loop shape and providing for finger tip gripping of edge portions of the shield whereby the latter may be opened or torn for the removal of the article and-the gripping and removal eiiected without injury to the article.

2. The method of packing a tenaciousthin film article of substantially cup-shape, which comprises first the step of rolling the article upon itself in successive peripheral folds from its open end to its closed end to form a circular ring of high resilient resistance to radial distortion and of spiral rim section webbed by the closed endof the cup, second, the step of radially distorting the ring into an elongated closed loop having slightly laterally spaced substantially parallel sides constituted by portions of the rim, and third, the step of forming a less tenacious and resilient flat sided elongated casing having at least one open end from which the flat sides have extensions, fourth, the step of pressing one end of said loop laterally against the inner tip side of one of said? extensions, and thereby pressing the latter outwardly to provide an enlarged entrance to the casing, and fifth, the step of sliding said loop ionrg'itudinally into said casing through said entrance untilthe trailing end of the loop is in the casing beyond the outer end of said extensions.

3i Inconmination in a package, a tenacious thin film article ofsubstantially cup-shape rolled upon itsell'in successive peripheral folds from its open end, to its closed endin the form of a circular ring 'ofhighresilient resistance to radial distortion and of spiral layer rim section webbed by the closed end of the cup, said ring being radially distorted into-aneiongated closed loop having slightly laterally, spacedsubstantially parallel sides constitutedby portions of the rim, and-a less tenacious and, resilient flat sided elongated, casing around the article entirely protecting and holding it in said loop shape. said casing having at least one open. end extendedbeyond the article providing for finger tip gripping of edge portions of the shield whereby the latter may be opened or torn for the removal of the article and the gripping and removal effected without injury to the article.
