I Th s invention relates ltotzbags'and more .particularlyto bags constructed for ventilation and viewing-of the. contents :of the'bag. I

invention;features"=the provision: of a improved ventilating bag made in part of an imperforate bagmaterial "such as paper andin part of afiperforate bag material such as an openmesh woven material,- of such construction that it may-be bottomed bystanda'rd-bag bottoming apparatus, wherein the imperforate bag material is used to form the lower end of thebag and is formed with a folded bag bottom of the type adapted to unfold flat when the bag is filledso that it will stand upright, for example, a satchel bottom, and wherein the perforate bag material is use'd'to form theupper or mouth end of the bag so that the bag mouth may be readily pro vided with a draw cord type of closure. Other features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the ele-.

ments and combinations of elements, features of construction, and arrangements of parts which will be exemplified in the structures hereinafter described, and the scope of the'application of which will be indicated in the followingclaims.

In the accompanying drawings, in which several of various possibleembodiments of the invention are illustrated, V a

H to expose their inside faces for application of adlres ive 'l ti .theretol One of the 'flaps ;(th e'flap Has illustr'at'ed) is provided with a 'thumb'" notch- TI to facilitate folding back the flaps.

The'upper tube section is designated 19 and V is shown in Fig. 1 to comprise a pre-formed tube of open-mesh woven material having an inturned stitchedside seam BI. Tube 19 may be made of any open-mesh material such as is ordinarily used in bag manufacture, for example -a leno or plain weave fabric woven from any suitable yarn, such as wet-strength paper yarn. A draw tape 83 is incorporated in the open-mesh material adjacent the upper open end of the tube 19 defining the mouth of the bag. Narrow ribbonsor tapes 85 of paper are. interwoven with the open-mesh material adjacent the open lower end of the tube 19 in the manner illustrated in U. S.-Patent 2,416,747 to close the mesh at the lower end. Thus, the lower margin of the openmesh tube is'formed as a substantially. imperforate band. The width of this imperforate band is at least equal to the width of the flaps H and I3.

The pre-formed open-mesh tube 19 is assembled with the pre-formed lower paper section 6| by applying its lower end between the adhesivefor the upper section of the bag of Figs. 1 and ,2.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings, Figs. 1 and 2 illustrate a bag. made in accordance with this invention having a lower tube section of imperforate bag material which is completely formed, including the forming of the bag bottom, prior to the application of an upper tube section of perforate materialallowing forventilation and viewing of the bag contents, the uppertube section also being completely formed prior to its assembly with the lower section. The lower tube section is designated 6| and is shown to be in the form of a conventional paper bag 63having asatchel bottom 65. in conventional manner by forming a paper .bag tube having theusual pasted seam 61 and then This'lower section maybe made bearing flaps H and 13 of the lower section 6| and pressing the flaps against the lower end of the tube'19 to cause them to adhere together. This results in the bag shown in Fig. 2. The ribbons 85 close the mesh throughout the area of the band of the tube 19 between the flaps H and 13 and thus prevent the adhesive from penetrating through the band and sticking the front and back walls of the finished bag together.

Fig. 3 illustrates a modified form of the openmesh upper section for a bag of the Fig. 2 type wherein the upper section, generally designated 89, is made of material woven with a close-mesh band 9| at its margin which is to form the lower end of the upper section. This close-mesh band or section is substantially imperforate to prevent adhesive from penetrating through the woven. material and sticking together the front and v back walls of the bag.

While the paper lower section 6| is shown as made of single-ply paper, it is contemplated that it may be made of multiple-ply paper. In this case, the plies would be united, as by adhesive or in any other suitable way, across the top of the section.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

We claim:

1. A bag comprising a tubular lower section made of imperforate bag material and formed with a bottom, said lower section having flaps at its upper end, and a tubular upper section made of perforate material allowing for ventilation and viewing of the bag contents having a substani. f

tially imperforate band at its lower end which is adhesively secured to the inside of the flaps,

the upper end of the upper section defining the tubular upper section made of open-mesh woven -0 material allowing for ventilation and viewing of the bag contents having a substantially imperforate band at its lower margin which is adhesively secured to the inside of the flaps, the upper end of the upper section defining the mouth of the bag. 7
