Application December 9, 1931. Serial No. 579,912
This invention relates to new and useful improvements in containers, generally, and more particularly to a container or bag of the general 'character disclosed in Patent No. 1,833,675.
An object of the invention is to provide a container made of iiexible foldable material having closure flaps adapted to be folded in overlapping relation and secured together to seal the top of the container, one `of said flaps having a plurality of perforations in a wall thereof whereby, when said ap is unfolded from the remaining fiaps, the material in the container may be filtered through the perforations in said flap.
A further object is to provide an improved container or bag of the-character described having its top Walls adapted to be folded to provide a plurality of iiaps which may be folded in overlapping relation and secured together to seal the top of the bag, and the uppermost ap being adapted to be unfolded from the remaining flaps and having a plurality of perforations in awall thereof, through which the material in the container maybe filtered or discharged, when said flap is unfolded, and whereby the container may be used as a means for uniformly spreading the material over the area to be treated.'
A further object is to provide an inexpensive and simple container for dispensing in small quantities, such materials as grass seeds, commercial fertilizers, and other smally materials which are usually spread over the surface to be treated, having means incorporated in the construction thereof whereby the material in the container may be filtered therefrom through a 'series of small apertures provided in a wall of one of the iiaps providing the closure for the container, and whereby the container itself may be used as a means for uniformly spreading the material over the surface to be covered. 4
The primary object of the invention, therefore, is to provide a container for dispensing such materials as grass seed, various other .small seeds, and commercial fertilizers, having means incorporated in the construction thereof whereby the material may be filtered from the container in such a fashion as to simplify the operation of uniformly spreading the material over the surface to be treated, and whereby the material may be applied to the surface directly from the container.
Other objects of the invention will appear from the following description and accompanying drawing and will be pointed out in the annexed claim.
In` the accompanying drawing, there has been and numerous other small seeds, and also varimay be made within the scope of the claim 60 which follows.
In the drawing:
Figure 1 is a view showing the folded top or a bag with the invention applied thereto;`
Figure 2 is a view similar to Figure 1, showing the uppermost flap partially unfolded.
Figure 3 is a view showing the uppermost iiap completely unfolded, and also illustrating the material being ltered from the container through the perforations provided ina wall of said i'iap;
Figure d is a view showing an empty bag with one of its walls perforated; and
,Figure 5 is a view showing a modified con struction.
In the selected embodiment of the invention herein disclosed, there is illustrated a container or bag comprising a body portion composed of end walls 2--2 and side walls 3-3. The upper portions of the bag walls are adapted to be folded to provide a plurality of flaps 4, 5, 6, and 7, which subsequently are folded, one over the other, in overlapping relation and suitably secured together to seal the bag.
An important feature of this invention resides in the means provided whereby the bag or container may he used as a means for uniformly spreading the material contained therein over a surface to be treated. Lawn seeds,
ous commercial fertilizers, are now commonly dispensed in small containers. It is rather dificult for an inexperienced person to uniformly spread or distribute lawn seed by scattering it over the area to be seeded by hand, which appears to`be the common method of planting grass seed by theaverage person. To overcome this dimculty and to facilitate the operation of spreading the seed over the ground, and also whereby it may be substantially uniformly spread, I have found that by providing a plurality of perforations or apertures 8 in a wall of one of the naps of the container, that when said perforated nap is unfolded, the material may readily be filtered from the container andf105 uniformly spread over the surface to be treated, as shown in Figure 3.
In a bag or container of the class illustrated in the drawing, the naps are usually composed of a plurality oi plies of material adapted to .hej-110 lOO separated to provide a space connecting with the interior of the bag, as best shown in Fig- `ure 3. The perforations 8 are preferably provided in the outer wall of the uppermost ap 7, so that when said flap is unfolded from the remaining folded iiaps, and the bag is tilted to an inclined' position, the material will enter the space in said unfolded iiap, whereby it may be discharged through the perforations 8, as shown in Figure 3. It is to be understood that the plurality of plies of material constituting the inner wall 9 of the ilap 'l are suitably secured together so that when the iiap is unfolded, the plies thereof will not separate.
When the tops of the bag wallslare folded into bag-sealing relation with the flaps d and 'I disposed in overlapping relation, the outer and inner walls of the top flap 'l will be disposed in engaging relation vso that the material in the bag or container cannot leak therefrom, when said flaps are thus folded.`
It will thus be noted that by -the provision of the perforations 8 in the top lap 7, when said iiap is unfolded to the position shown in Figure 3, the material may readily and conveniently be filtered fromthe container through said apertures in a plurality of small streams, 'whereby the material may readily be uniformly spread over the surface to be treated. This novel container therefore, readily lends itself for use in the dispensing of lawn seeds and other small seeds, as Well as various kinds of commercial fertilizers. y
Figure illustrates'a modified construction wherein a plurality of score marks 9 are 'shown provided in the edges of the -lap 7 in lieu oi the perforatlons 8 shown in Figures 1 toll. The portions l0 defined by the score maries 9 may readily be torn or severed from the nap to pro aeerfesa closed, as it provides means whereby the con? tents of the bags may readily and conveniently be ltered therefrom by slightly shaking the bag so as to uniformly spread the material over the surface to be treated. `also, by providing the periorations 8 in the outer wall of the unfold-` able fiap 7, when the ap is folded to the position shown in Figure l, the perforations will'be sealed or closed so that the 'material cannot discharge or leak from the container.
I claim as my invention:
A bag made of eizible, foldable material comprising a plurality of walls cooperating to provide the body of the bag and having portions forming the walls of the bag mouth, said Wall portions being folded into a plurality of closure flaps which flaps are folded in overlapping relation and secured together to seal the top of the bag, at least one of said aps being composed of a lplurality ofl plies of material adapted to be separated to provide a space com municating with the interior of the bag, and said last-mentioned nap being substantially triangular in configuration and having a plural- |ity of spaced score marks in its edges whereby portions of said ap may readily be torn or detached therefrom to provide suitable aper` tures or openings through which the contents of the bag may be discharged or sifted, when the ap is unsealed and without unsealing the remaining aps.
