PROTECTIVE SHATTERPROOF' OUTER CONTAINER FOR BOTTLE Filed Feb. 9, 1953 INVENTOR. f] /VALO G. /W/IG/ BY M i/ M PROTECTIVE SHATTERPROOF OUTER CQNTAINER FOR BOTTLE Donald G. Magill, Great Neck, N. Y., assignor to American Can Company, New York, N. Y., a corporation of New Jersey Application February 9, 1953, Serial No. 335,847

Claims. (Cl. 299-95) The present invention relates to protective containers or cans and has particular reference to a shatterproof outer container for pressurized glass bottles.

Certain types of insecticides and other liquids because of their high corrosive nature are preferably packed in glass bottles to overcome excessive corrosion of the container. Where such bottles are provided with a spray attachment for dispensing the contents, a gas under pressure is included in the bottle to provide a propellant for the liquid. The thus pressurized bottle often is dangerous to handle and is liable to explode with a resulting injurious blast of flying glass, if the bottle is dropped or the pressure becomes to excessive.

The present invention overcomes this danger by providing an enclosing economically constructed protective outer container for the bottle which effectively withstands the hazards of handling and shipping.

An object of the invention is the provision of a protective outer container for a pressurized glass bottle wherein the container completely encloses the bottle and is shatterproof so that dying glass caused by bursting of the bottle for any reason, is confined within the container and is thus prevented from inflicting personal injury.

Another object is the provision in such a protective container of a venting feature to permit ready escape from the container of the gas released from a burst bottle so as to greatly reduce the impact applied directly to the walls of the container.

Another object is the provision in such a protective container of cushioning and spacing means which cushion the bottle and which hold the bottle in a centralized position so as to prevent breaking of the bottle under minor impacts while yet protecting against injury in the event the bottle should explode.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawing:

Figure l is a perspective View of a protective outer container embodying the instant invention, with a portion broken away to disclose a portion of the bottle enclosed in the container;

Fig. 2 is an enlarged sectional view of the container shown in Fig. l, with the bottle enclosed therein shown in full;

Fig. 3 is a reduced scale sectional View taken substantially along the line 3 3 in Fig. 2; and

Fig. 4 is a fragmentary view of the lower corner of Fig. 2 and showing a slightly diiferent construction of the container. l

As a preferred or exemplary embodiment of the instant invention the drawings illustrate a protective outer container for a pressurized glass bottle 11 having a reduced neck 12 sealed with a cap 13 such as a crown cap or other closure. The cap 13 preferably carries a spray nite States Patent f' 2,756,105 Patented July 24, 1956 nozzle 14 of any conventional character for dispensing the liquid contents of the bottle.

The protective outer container 10 preferably is of the composite type, comprising a shatterproof cylindrical tubular body 16 of tough high tensile strength kraft paper or fibre and shatterproof sheet metal top and bottom end closure members 17, 13 respectively secured thereto in suitable seams 19 such as the conventional double seam or crimped seam effected by interfolding flange portions of the end members with the body.

The inside diameter of the fibre body 16 is slightly greater than the outside diameter of the bottle 11 to provide a clearance space around the outside of the bottle for the free escape of gas in the event the bottle breaks.

Inside the body 16 and adjacent the bottom end member 1S, the container 1l) is provided with a cushion 21 on which the bottle rests to cushion the bottle against breakage under minor impacts, such as accidental dropping of the container through a short space or extra hard impact of the container with a table or other support. This cushion 21 preferably comprises a corrugated fibre disc or member 22 having top and bottom smooth bre faces 23, 24.

ln order to provide for the free escape of gas in the event the bottle should break, the cushion 21 is formed with a central concentric opening 26 and a plurality of spaced smaller openings 27 (see Fig. 3) arranged in a circle around the central opening. These openings 26, 27 extend entirely through the cushion from face-toface to permit the outward passage therethrough of the gas. For cooperation with these openings, the bottom end member 18 is provided with a plurality of smaller openings 28 which are arranged in a circle below the openings 27 in the cushion but not directly in alignment with these openings, the openings 27, 28 being slightly staggered to prevent passage therethrough of fragments of glass in the event the bottle breaks.

At its upper end, the container 16 contains a centralizing or holding cushion 32 which is similar to the bottom cushion 21 and which ts snugly in the container body 16 and around the neck of the bottle to hold the bottle in a central location in the container. This cushion 32 comprises a fibre corrugated disc or member 33 having smooth top and bottom libre faces 34, 35. A central concentric opening 36 in the cushion from face-to-face is provided for the neck 12 of the bottle. Around this central opening, the cushion is provided with a plurality of spaced smaller openings 37 which are arranged in a circle and which extend entirely through the cushion from face-toface to permit of the free outward escape of gas in case the bottle should be broken.

The top sheet metal end member 17 attached to the body 16 by way of the end seam 19 preferably is formed with a raised re-enforcing panel 41 provided with a plurality of openings 42 arranged in a circle to permit of the free outward escape of gas from the container in the event the bottle is broken. The panel 41 is formed with a central raised panel 44 which is concentric with the container body 16 and the top end member 17 and sets off an inner locating recess 45 of a depth and diameter suicient to snugly accommodate and seat the cap 13 of the bottle 11 to rigidly hold the bottle 11 in its centralized location in the container. This locating panel 44 constitutes a portion of the end member 17 and is utilized even though the re-enforcing panel 41 is dispensed with. A central opening 47 in the locating panel 44 is provided for the dispensing nozzle 14 of the bottle. This dispensing nozzle 14 is the only portion of the bottle that extends outside of the container 10 and is usually made of some material other than glass so that it is nonshatterable.

3 Thus the entire shatterable portion of the bottle 11 is securely enclosed in a nonshatterable container which confines the fragments of glass and permits the free escape of gas in the event the bottle is broken.

Since the top and bottom cushions 32, 21 in the container absorb most of the endwise impact of an exploding bottle, the end members 17, 18 may be made of tibre material instead of sheet metal if desired. Figure 4 shows a container iitted with such ends. Although only the bottom end is shown the top end may be made identical with the bottom. In such a construction, a heavy fibre disc end member 52 of substantially the same diameter as the inside diameter of the body 16 is snugly fitted within the body and the marginal edge portion or ange of the body is turned inwardly and back on itself to provide a stop or supporting shoulder 53. This shoulder abuts against and firmly supports the end member 52 against outward displacement and in most cases is just as etective as a double or other interfolded seam.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes maybe made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
