Application January 14, 1936, Serial No. 59,045 3 Claims. (Cl. 299-24) 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 5:1 improved fiunigating device which may be ap plied to boxes, bags, or other large or small arti~ cles 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 1.? 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 TD vi 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 some what similar to Fig. 2 but showing a modi?ed 4 O 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 func tion properly to give off gas or to supply gas to the contents of containers for fumigating pur poses. As shown in Fig. 1, bag I is an ordinary paper U bag and is supplied with a reinforcing bottom 2. rThis 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 10 slightly modi?ed 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 pro vided 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 pre sent a ?ange 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 ?aring edge i3 which extends outwardly radially almost as far as ?ange Hi. When the sections 5 and ii are screwed tightly together the flange ii] and 0 ID 3 edge l3 will tightly pinch the reinforcing bot tom 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 ?ange Ill and edge 3 ex I k, tend when these parts are permanently posi tioned. This provides a gas tight connection at this point. Section 6 is provided with an inturned ?ange l5 which in effect produces an aperture 16 through 4 i which the cartridge ll loosely extends. The car tridge ll is preferably made from one piece of sheet metal and is formed with a bottom I8 bent back at 19 to produce a ?ange, and said ?ange 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 50 size container, as for instance a bushel bag, ap proximately one tablespoonful of the disinfectant is ample, and as cap 22 is gas tight the disin fectant will remain in the cartridge l‘l until cap 22 has been removed. As shown in Fig. 3, the 2. 2,105,551 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 fric tion 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, vege tables, and other articles which need fumigation. 10 For this reason the cap ll‘is formed as just de scribed, and if desired may be ?lled with loose cotton or Waste, and then the article is shipped to the desired point. The various cartridges I‘! are ?lled by experienced Workers and then sealed by screwing cap 22 in place, after which a desired supply of these ?lled cartridges are shipped under proper authority to the same person receiving the bags and other articles. This person then un screws 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 ?ll the bag or other container and secure the desired fumigating and disinfecting action. If desired, instead of having a screw cap 22 a stop per of any kind which will be substantially gas tight would‘be 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 fumi 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, com prising a pair of interlocking sections, and means for holding a fumigating material in place, one of said sections presenting a bottom member hav ing an aperture, a radiating flange and a threaded tubular body, the other of said members present ing a threaded tubular body adapted to be screwed onto the ?rst mentioned body, said second men tioned section having a ?aring 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 ?ange, said ?ange 1 merging into a body having a centrally posi tioned aperture, and a plurality of slits radiating from said aperture, said capbeing formed with an outside section having an innerextending ?ange, a tubular body screwed onto the ?rst mentioned body, and a ?aring edge coacting with said ?ange 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 30 gating‘. material has been supplied. For instance, the cap 4 is adapted to be ?lled with loose cotton, and, if desired, a pastel’ of paper or other material ing part of the cap for clamping the same in place, said cap having an apertured bottom formed'with could be placed over opening 8. Bag l with its contents is then shipped to its desired point and radiating slits, and a iumigating materialcarry ing cartridge extending through said apertured 35 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 the bottom of a bag or other article, means form- ‘ bottom, said cartridge being of a size greater 5'1 in diameter than said aperture whereby portions of said threaded body are moved out of the way when the cartridge is forced into position.
