VALVE BAG CLOSURE Filed June 20. 1929 INVENTOR Harrison R. Williams. BY @wWfM A TTORNEYS Patented June 7, 1932 UNETED ST TES HARRISON n. WILLIAMS, or new YORK, N. Y.
VALVE BAG otosunn Application filed June 20,
This invention relates to valve bags, and has for its principal object the provision in such a bag of a valve-control element slidable between the plies of the bag gusset to open and close the bag valve.
Another object of the invention is the provision of means for readily operating the valve-control element.
The invention will best be understood by in reference to the accompanying drawing, wherein is illustrated the present preferred embodiment thereof and in which Figure 1 is an illustration of a paper bag embodying the invention, a portion of said bag being shown as broken away in order to disclose the structural features and the position of the valve-control element when the valve is open.
Figure 2 is a fragmentary View similar to as Figure 1, but showing the bag valve as closed.
Figure 3 is a sectional view taken on the line 3-3 of Figure 1.
Figure 4 is a perspective view of the valvecontrol element. 7
Figure 5 is a fragmentary detailed view of the valve-control element illustrating one of the eyelets with which the same is provided.
39 Referring to the drawing, the paper bag here illustrated and designated generally by the reference numeral 1 is of the multipleply type, the ends thereof being folded over and sewn in order to close the same.
The two plies of the bag are indicated respectively by the reference numerals 2 and 3. It should be understood that instead of the two plies 2 and 3 many plies may be used. These plies are folded to form a gusset ex 4 0 tending along one side of the bag and denoted generally by the reference numeral at. The apex of the gusset is perforated near one end thereof to provide a valve or opening 5, through which a filler-tube may be inserted. Slidable in thepocket formed by the walls of the gusset 4 is a valve-control element preferably made of cardboard or similar material, and designated generally by the reference numeral 6. This valve-control 59 element is folded longitudinally in order to .contents.
1929. Serial no. 372,276.
conform generally to thepocket defined by the gusset walls, and has mounted in one of its leaves two eyelets 7 and 8.' Passing through eyelet 7 and tied therein is a valveclosing cord -9; and similarly tied in eyelet 8 is a valve-opening cord 10. As appears from Figs. 1,2-and 4,these cords are installed inthe pocket formed byrthe gusset walls, the valve-closing cord 9 extending beyond the top of-the bag body and the valve- (0 opening cord -10eXtending beyond the bottom thereof. Pulling ofcordlO results in the opening of the valve, as shown in Fig. 1, in order that it may be filled or discharged; while pulling of cord9 results in the closing 55 of the valve to prevent leakage of the bag i, The invention provides a valve bag which is simple in construction, economical to manufacture, and which readily and effectually 7 may be opened and closed. d
i I have describedwhat I believe to be the best embodiment of my invention. I do not wish, however, to be confined to the embodiment. shown, but what'I desire to cover by} 7 Letters Patent is set' forth in'the' appended claims.
I claim: 7 I I 1. A bag provided with a gusset having an aperature therein, a dihedral valve member 30 straddling the gusset, and a control element for said valve slidable longitudinally of the gusset.
2. A bag provided with a multiple-ply gusset apertured to form a valve and control means for said valve slidable in a pocket defined by the plies of said gusset.
3. A bag provided with a gusset apertured to form a valve, a control element for said valve slidable along the gusset, and means ex- '90 tending through opposite ends of the bag for manipulating said control element to open and close the valve.
4. A multiple-ply bag provided with a gusset apertured to form a valve, an opening and closing element for said valve, and cords extending through opposite ends of the body of the bag for actuating said opening and closing element between valve closing and valve opening position.
5. A bag provided with a multiple-ply gusset apertured to form a valve, the walls of said gusset defining a pocket, and a folded cardboard element slidable in said pocket and constructed and arranged to open and close said valve.
6. A bag provided with. a-fillingand.discharge aperture, afolded element interfitting with a bag fold and slidable talongmthe same for controlling saidaperture, and cords for manipulating said slidable element.
7. A bag provided with a fillinganddischarge aperture and a slidable cardboardele ment for controlling said; aperture, said cardboard element being provided with a plurality ofeyelets and with cords tiedthereimfor ,manipulatingi said element to ;.open1'andv close said aperture.
- =8. .A rbag'ihaving a-multiple-plyggusset apertured to provide a filling anddischarge valve and a manually-operable slidablecontrol element for said valve substantially coextensive in widthwiththe gusseted wall of the bag.
9. Abag having a multiple-ply: gusset apertured toiprovide a'filling and discharge valve and a 1 manually=operable control element for said valve slidable between the plies of said gusset.
10. A bag having a multiple-ply: gusset apertured to provide a filling and discharge valve and a control element for said val've constructed and arranged 'to conform 'to" the space defined b the wallsof'saidgus'set and slidable in sai Space.
11. A bag provided-with a-multipleply gusset apertured to'form avalve, and a folded cardboard controlclement for opening and closing said valve,-'said control element having a plurality of eyeleted apertures'with cords tied therein and extending 'beyoiid 'the body of the bag.
Intestilnony whereof I have afiix'edmysignature.
