Jan. 18, 1938. w. c. PURDY FUMIGATING DEVICE Filed Jan. 14, 1936 INVENTOR ZUZZZZam O. Pura ly BY P M W ATTORNEYS lb in esses Patented Jan. 18, 1938 ra s FATENT GFFICE 3 Claims.

This invention relates to fumigating devices, and particularly to improved devices adapted to sup-ply desired fumigation to bags, boxes, or other containers of any size.

An object of the invention is to provide an improved fiunigating device which may be applied to boxes, bags, or other large or small articles in such a way that the fumigating material may be supplied at any time.

Another object of the invention is to provide a fumigating device in the nature of a cap adapted to be more or less permanently mounted and coacting with a removable cartridge which is designed to carry the fumigating material.

An additional object is to provide a fumigating device which may use a cartridge for supplying the fumigating material.

An additional and further object is to provide a fumigating device wherein a cap is presented which may be quickly and easily applied to a paper bag, a box, or other object, and when so applied will present a substantially air tight con nection with the bag or other article.

In the accompanying drawing:

Fig. 1 is a longitudinal vertical sectional view through a bag having an embodiment of the invention applied thereto;

Fig. 2 is an enlarged fragmentary sectional view through the center of the cap and certain associated parts shown in Fig. 1;

Fig. 3 is a view similar to Fig. 2 but showing a fumigating carrying cartridge;

Fig. 4 is a bottom plan View of the cap shown in Fig. 1;

Fig. 5 is an edge view of a foraminous plate which may be used in connection with the cap shown in Fig. 2;

Fig. 6 is a fragmentary sectional view somewhat similar to Fig. 2 but showing a modified form of the invention.

Referring to the accompanying drawing by numerals, I indicates a bag which may be an ordinary paper bag of any size or shape. This bag may have a fumigating device embodying the invention applied directly thereto, or the bag may be placed in a crate or box and the device applied to the bag and box as a unit. This sometimes is desirable as boxes quite often become broken more or less during handling, with the result that fumigating gases will escape. Where a paper bag lines the box, a slight breaking of the box would not break the bag, and consequently a fumigating gas in the bag would remain and perform its desired function. However, regardless of how the container is formed, the cap and associated parts forming the invention will function properly to give off gas or to supply gas to the contents of containers for fumigating purposes.

As shown in Fig. 1, bag I is an ordinary paper bag and is supplied with a reinforcing bottom 2. This bottom may be corrugated paper, ordinary pasteboard, laminated wood, or other material which will provide means whereby the device may be connected to the bag. As shown in Fig. 6, a slightly modified structure is provided wherein a rather small ring 3 of corrugated paper or other material is secured to the bottom of the bag by adhesive and thereby presents ample thickness and ample strength for receiving the cap 4. The cap 4, as shown in Fig. 2, is formed in two parts, namely the inner part or section 5 and the outer part or section 6. Section 5 is provided with a bottom I having an aperture 8, and radiating from this aperture is a number of slits 9 as shown particularly in Fig. 4.

The bottom 7 is bent back upon itself to present a flange l6 which merges into a tubular threaded portion H. The threaded portion H is adapted to receive the threaded portion l2 of section 6, which section at the lower end as shown in Fig. 2 is provided with a flaring edge i3 which extends outwardly radially almost as far as flange Hi. When the sections 5 and ii are screwed tightly together the flange ii] and 0 edge l3 will tightly pinch the reinforcing bottom 2 and also the bottom of bag 1. If desired, glue or other sealing means may be provided near the edge of the aperture or hole M of mem ber 2 into which the flange Ill and edge 3 extend when these parts are permanently positioned. This provides a gas tight connection at this point.

Section 6 is provided with an inturned flange l5 which in effect produces an aperture 16 through which the cartridge ll loosely extends. The cartridge ll is preferably made from one piece of sheet metal and is formed with a bottom I8 bent back at 19 to produce a flange, and said flange merges into a tubular body 20. The body 20 has a threaded end 2| onto which the threaded cap 22 is screwed; The cartridge l! is adapted to carry the disinfectant and may be supplied with loose cotton or waste 23, and to this Waste is poured the liquid disinfectant. For an ordinary size container, as for instance a bushel bag, approximately one tablespoonful of the disinfectant is ample, and as cap 22 is gas tight the disinfectant will remain in the cartridge ll until cap 22 has been removed. As shown in Fig. 3, the

diameter of body 26 is larger than the aperture 8, and consequently the parts or prongs are bent up- Wardly as indicated at 25. When the cartridge is forced into position, this produces a certain friction which holds the cartridge in place.

Most disinfecting material is more or less dangerous and consequently railroads will not ordinarily transport the same with nuts, vegetables, and other articles which need fumigation. For this reason the cap l is formed as just described, and if desired may be filled with loose cotton or Waste, and then the article is shipped to the desired point. The various cartridges I! are filled by experienced Workers and then sealed by screwing cap 22 in place, after which a desired supply of these filled cartridges are shipped under proper authority to the same person receiving the bags and other articles. This person then unscrews cap- 22 from the respective cartridges and forces the cartridges? into the caps 4 as shown in Fig. 3, whereupon the gas from the disinfectant will fill the bag or other container and secure the desired fumigating and disinfecting action. If desired, instead of having a screw cap 22 a stopper of any kind which will be substantially gas tight wouldbe satisfactory.

In all forms of the invention it will be observed that the container is substantially sealed at all times both before and after the gas or other fumigating material has been supplied. For instance, the cap 4 is adapted to be filled with loose cotton, and, if desired, a pastel of paper or other material could be placed over opening 8. Bag l with its contents is then shipped to its desired point and at the desired point someone could insert the cartridge H after cap 22 has been removed. In this way the articles being shipped are shipped in a substantially sealed condition without an fumigating material therein. This will readily comply with all the rules and regulations of the railroad companies and insurance companies. After the goods have arrived the fumigation may take place as above described.

I claim:

1. A fumigating structure for a container, comprising a pair of interlocking sections, and means for holding a fumigating material in place, one of said sections presenting a bottom member having an aperture, a radiating flange and a threaded tubular body, the other of said members presenting a threaded tubular body adapted to be screwed onto the first mentioned body, said second mentioned section having a flaring edge coacting with said flange for pinching the bottom of a bag or other article.

2. In a device of the character described, a cap comprising a tubular body threaded substantially for its entire length, said body at one end merging into an annular radiating flange, said flange 1 merging into a body having a centrally positioned aperture, and a plurality of slits radiating from said aperture, said capbeing formed with an outside section having an innerextending flange, a tubular body screwed onto the first mentioned body, and a flaring edge coacting with said flange for pinching the bottom of a bag or other article.

3. In a device of the character described, a. cap formed with a body adapted to extend through the bottom of a bag or other article, means forming part of the cap for clamping the same in place, said cap having an apertured bottom formed'with radiating slits, and a iumigating materialcarrying cartridge extending through said apertured bottom, said cartridge being of a size greater in diameter than said aperture whereby portions of said threaded body are moved out of the way when the cartridge is forced into position.
