A. MATTER.

COVERED BOX.

APPLICATION FILED AUG.28, 1919.

Patented May 30, 1922.

fnvenfior- ALBERT J. MATTER, OF MERRIMAC, MASSACHUSETTS, .ASSIGNOR, BY MESNE ASSIGN- MENTS, TO GEO. J, KELLY, LNG, OF LYNN,MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

COVERED BOX.

Specification of Letters'Patent.

Patented May 30, 1922.

- T all whom it may concern:

Be it known that I, ALBERT J. MATTER, a citizen of the United States, residing at Merrimac, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Covered Boxes of which the following is a specification, rererence being had therein to the accompanying drawings.

The invention relates to boxes provided with removable covers having depending rims or flanges which surround and tightly clasp cylindrical portions or shells of the box-bodies. More particularly, it has relation to boxes of the class in which the depending rims or flanges of the. covers are formed with flaring portions, inward pressure upon which expands the rim or flange of a cover in a manner that loosens the lit of the cover upon the box-body and facilitates its removal from the latter.

A defect and drawback of boxes of the said class as heretofore made has been the fact that the flaring portions aforesaid,

which for convenience of designation may be termed expansion flares, are unprotected, and are exposed to blows and external pressure. From accidental causes, therefore, it happens with more or less frequency that'the boxcovers become prematurely expanded and loosened. This happens, for instance, in the case of filled boxes packed in cases, under conditions which produce movement and pressure of the boxes transversely against one another. When pressure due to transverse movement, or to weight, or to transmitted shock, takes effect against expansion flares it sometimes occasions the expansion and loosening of the box-covers. This may result in escape of the box-contents or of the volatile constituents thereof, or in injury to the said contents through the admission of air. In the case of shoe-blacking paste, for example, the boxes must remain sealed in air-tight condition, and loosening of the boxcovers is followed by injury to the paste.

The invention provides protection for the expansion flares in question, whereby they are shielded from simple pressure and from blows.

An embodiment of the invention is illustrated in the drawing, which shows in vertical cross-section a box containing the said embodiment.

In the drawing the box-body is marked 1,

and 2 is the box-cover. The upstanding cylindrical portion or shell of the box-body is marked 1 and the depending cylindrical rim or flange of the cover which fits upon the said upstanding cylindrical portion or shell is marked 2. The cover-rim or flange aforesaid is formed with an expansion flare or flares 2 2 and 2 is an inwardly projecting bead of the cover-rim or flange, which by contact with the top edge of the box-body serves as a stop to limit the extent to which the cover may be pushed down upon the body.

In accordance with the invention I provide the members of the box, with radial prominences a, a, the relations being such that when the body and cover are fitted together the prominences a, a, occupy positions respectively below and above the expansionflare or flares 2 2 so as to shield the latter. They preferably are formed by moulding the vertical portions of the body and cover, and may extend either continuously or only partially around the box, according as the cover is formed with a continuous flare or with one or more discontinuous flares. They may be of any approved shape in vertical cross-section and are sufliciently large vertically to ensure that those of adjoining boxes shall make contact with one another and thereby perform their intended function of preventing pressure upon the expansion flare or flares 2 2 which will operate to loosen a cover.

The shielding prominences a, a, prevent contact between the expansion flare or flares 2 2 of one box with adjoining boxes, or

between such flare or flares and the sides of the container in which the boxes are packed for transportation or storage.

lVhat is claimed as the invention is,

A box comprising a body and cover fitting together as described, said cover having an expansion flare construction by which its fit upon the box-body may be loosened through.

pressure, said box-members provided with radially projecting shields, respectively above and below the flare or flares.

In testimony whereof I aflix my signature in presence of two witnesses.

ALBERT J. MATTER.
