Patented May 11, 1937 PATENT OFFICE PACKAGING DEVICE Myron S. Strasser, Albany, N. Y. Application January 10, 1936, Serial No. 58,584

2 Claims.

My invention relates to packaging devices and particularly to a device for use in loading packages or containers of the type described in my copending application Serial No. 45,237 filed Oc- .5 tober 16, 1935.

In my said copending application I have disclosed a collapsible container comprising two principal elements; one, an open frame of cardboard or the like, and the other, an outer cover- .10 mg or envelope for the frame which may be an ordinary paper bag. The frame forms the interior sides and ends of the package, and the outer envelope forms the top and bottom thereof; the frame being of such size that when in 15 serted in the envelope it will distend the same substantially to capacity.

.In order to load or fill such a package the open frame is placed upon a substantially horizontal surface, the goods placed therein, and

the outer envelope or bag then slid over the frame and its contents. In the aforesaid application, forexample, I have disclosed a scoop like receptacle upon which the frame may be placed for loading. The goods to be packaged are then laid in the scoop. within the frame, and the whole is then inserted in the bag and the scoop afterwards withdrawn.

The primary object of the present invention is to provide a cheap, eificient loading device for packages of this character which may be afiixed to a table or other base and which will form a support for the frame during the filling thereof. When the frame is filled, the outer bag or envelope may be slipped over the loaded frame and 35 the supporting means and the envelope afterwards withdrawn from the support with the frame and its contents therein.

With these objects in view, my invention includes the novel elements and the combinations and arrangements thereof described below and illustrated in the accompanying drawing in which-- Fig. 1 is a perspective view of my device showing, in dotted outline, the frame positioned 45 therein;

Fig. 2 is a plan view of the device with the frame therein and showing a fragmentary portion of the envelope drawn over the frame and loader;

50 Fig. 3 is a sectional elevation view in the plane 3--3 of Fig, 2; and

Figs. 4 and 5 are perspective .views showing modifications of my invention.

Referring to the drawing, my device is pref- 55 erably made of thin sheet metal such as stainless steel, but of sufiicient thickness, however, to provide the necessary structural stiffness.

In the embodiment shown in Figs. 1, 2, and 3, the device is represented generally by the numeral l and comprises a base plate 2 and side plates forming

upstanding flanges

3 and 4. The side plates at one end are extended downwardly, as shown at 5 and 6, and the bottoms of the downwardly extending portions 5 and 6 bent inwardly, as shown at I and ,8, to form supports for the device and through which screws 9 may be inserted to secure the loader to a suitable base, such as a table top 50. There is thus formed a sort of open-end trough or scoop supported at one end only and extending horizontally outwardly from the supports as a cantilever to provide a clear space H between the table top and the bottom of the base plate 2. The end of the trough remote from the supports is open, as shown at l2, while a fixed diaphragm l3 extends across the trough near the supported end and forms a closure therefor. The distance between the open end of the trough and the diaphragm 13 may be substantially equal to the length of the frame used in the package, and the width of the trough, that is to say the distance between the inner sides of the

upstanding flanges

3 and 4 should be substantially equal to the width of the frame used in the package. If desired, a movable diaphragm Hi may also be provided to push the loaded package from the device and, in order to facilitate this operation, a push rod l5 may be connected to the diaphragm l4 and slide in a suitable bearing I6 secured to the diaphragm IS. The height of the

flanges

3 and 4 above the level of the base plate 2 should, of course, not exceed the depth of the frame employed in the package and is preferably made somewhat less than the depth of the frame.

In Fig. 4 I have shown a modified type of loader similar to that shown in Figs. 1, 2, and 3 except the diaphragms l3 and I4 are omitted and the device is essentially a trough open at each end.

In Fig. 5 I have shown a further modification which is an open end trough supported at the center and really forming two loaders because a bag may be slipped over the end of either cantilever.

In operation, the cardboard frame H, which is ordinarily foldable or collapsible, is opened or expanded and placed in the trough as shown; it being understood that if a movable diaphragm I4 is employed that this diaphragm is retracted so as to be substantially in contact with the fixed diaphragm l3 thus leaving an open space in the trough of a length and width substantially equal to the length and width of the frame placed therein. The goods or materials which are tobe packaged are laid within the frame I! and, of course, rest upon the base plate 2. When the frame is completely loaded, the outer envelope I8 is drawn over the open end of the trough, as shown in Figs. 2 and 3, and the envelope with the frame therein is then slid from the loading device either by pushing on the innermost end of the frame with the hand or by manipulating the push rod I to force the movable diaphragm I 4 against the end of the frame and thus push the whole loaded package from the device.

In order to prevent the bag or envelope from catching on the ends of the

upstanding flanges

3 and 4 these may be rounded off", if desired, as shown at l9 and 20.

ince the goods to be packaged would ordinarily be supported upon a table, I prefer to secure my device directly to the loading table. On the other hand, it is to be understood that the supports may be extended sufficiently so that the trough may be secured to the floor at a convenient elevation for the loading operation.

Wherethe goods to be packaged are of small size, such, for example, as a single tooth brush, the loading trough or channel may be conveniently held in the hand instead of being secured to a table. In such case no means for supporting the trough as a cantilever is necessary.

While I have described my invention in its preferred embodiments, it is to be understood that the words which I have used are words of description rather than of limitation. Hence, changes within the purview of the appended claims may be made without departing from the true scope and spirit of my invention in its broader aspects.

What I claim is:

1. A device for loading a package comprising an outer envelope or bag permanently closed at one end, and a flexible, collapsible frame adapted to fit closely within said envelope and to distend it substantially to capacity; said device comprising a substantially horizontal base plate and vertical side plates of thin sheet metal forming a trough or scoop-like structure open at least at one end; said trough or scoop having a vertical depth slightly less than the vertical depth of said frame, and a length and width approximately equal to the length and width, respectively, of said frame; said side plates extending horizontally beyond and vertically below the bottom of said trough at the end opposite the open end thereof and adapted to be secured to a table top or the like, whereby to support said trough as a cantilever over which said envelope may be freely drawn when said frame is positioned in said trough until the end of said frame is substantially contiguous to the permanently closed end of said envelope. 2. A device for loading a package comprising an outer envelope or bag permanently closed at one end, and a flexible, collapsible frame adapted to fit closely within said envelope and to distend it substantially to capacity; said device comprising a trough or scoop-like structure open at one end and closed at the other, and formed of thin sheet metal; said trough having a. length and width substantially equal to the length and width of said frame and a vertical depth not exceeding the depth of said frame; the sides of said trough extending rearwardly and downwardly beyond the closed end thereof to form supporting legs, and being provided at the bottom of said downward extensions with angularly disposed portions adapted to rest upon and be secured to a table top or the like to support said trough as a cantilever; the exterior bottom of said trough presenting a smooth, plane surface free of projections from end to end thereof, whereby said envelope may be drawn entirely over said trough and lie substantially in contact therewith throughout the exterior bottom thereof.
