BAG SUPPORT Filed Jan. 6, 1951 INVENTOR mam? ATTORNEY United States Patent BAG SUPPORT Robert M. Dunning, St; Paul, lVIinm, assignor to Waldorf Paper Products Company, St. Paul; Minn, a corporation of Minnesota Application January 6,1951, Serial No. 204,800

1 Claim. ((31. 20678) This invention relates to an improvement in bag supportand deals. particularly with a card of paperboard or the like tov which a relatively flexible and pliable bag is-secured.

In the packaging of nut meats. and similar materials, it has become; common practice to seal these products in bags of cellophane or similar thinplastic or cellulosic materials. Where the bags are designed tosupport considerable weight, difiiculty is sometimes experienced in mounting the bags on a display rack or the like. Furthermore, it is sometimes desirable to mount the. bags and their contents against a cardboard backgound so that the contents show up more effectivelythan wouldotherwise be the case. In View of the fact that the; complete products are sometimes sold at an extremely low price, the. cards must be extremely inexpensive. Furthermore, for the same reason the cost of mounting the bags upon; the cards must also be very low.

The. object of the present invention lies. in the provision of a card to which a bag containing. a product may be mounted; The card is possessed of dimensionsv only slightly greater than the size of the bagso-that a minimum amount of paperboard is used.

A feature of the present invention resides in the provision of a supporting card for a bagged product which acts to conceal the major portion of the bag ends. Bags of the type in question are often made by sealing the ends of a tubular bag body. In sealing the bag ends, the bag is often pressed between ribbed and heated dies which heat seal the opposite sides of the bag together. This ribbed and sealed end is usually made opaque by the.

sealing operation and is less attractive than the remainder of the bag. Furthermore, this sealed bag end is stronger than the remainder of the bag due to the fact that it comprises two plies of material secured together. Therefore by sealing the bag and by securing it through the sealed bag ends, a more attractive structure is provided and the resulting structure is stronger than would otherwise be possible.

A further feature of the present invention lies in the provision of a card support for bags and the like which require a minimum of paperboard. I provide one or more flaps cut from the body of the bag and foldable out of the plane of the remainder of the card so that the flaps may overlie the sealed bag ends. By inserting a staple or similar fastener through the bag and through the card, the bag may be supported with the sealed ends thereof concealed while at the same time the card is only slightly greater in length and width than the bag itself.

A feature of the present invention lies in the simplicity of the construction. The flaps are so arranged that they may be folded out of the plane of the center portion of the card by merely folding the ends of the card at right angles to the body. When thus folded the space between the flaps is suflicient to accommodate the entire bag. By then folding the flaps back toward the plane of the remainder of the card and by inserting a staple through Figure 3 is a perspective view showingtthe: bag support in position to receive the bag.

Figure 4 is a view ofadetail portion of a modified form of construction.

The bagsupporting card is indicated in general by the letter A and is designed to'support; a bagv B. The bagB is usually of the type illustratedin-Figure 3 of the. drawings. and. includes a, generally tubularbody .10-haviu'g sealed-ends 11 and 12. The sealed ends 11 and 12. are preferably produced by rolling the bags between. heat sealing rollers or: heat sealing; bars; although adhesive may be employed if desired.

The ends .11 and 1 2 ,of thesbagtbodry; are usually rendered. somewhat opaque. by thewhea-t sealing process and; are less-attractive than the body of the bag. The bag bodyis. usuallytransparent-to,- cl'early-show'the bag contents. One; of the purposes. of; the presem: invention is-to-provide a-backing sheet; for the: bag which provides abetter: display of the. contents. At the, same, time, how:- ever, the. cardprovides; a simpktmeans. of advertisingthe product as weliaspother; products; it: isallsua'lly less expensive to print upon the paperboard cards than it-fs to: print; upon transparentbags; euiaeeordinghr'part of the. cost of; the-card is compensated for by the. lower price. of theprint-ing operation.-

The: card A includes'a; fiatpard body,- 13: which extends substantially-the full length-ofwthe. bag: B..-. Aapairt of score lines 14 extend inwardly in aligned relation near one end of the bag, separating a portion of the bag body from the card end 15. A generally U-shaped out line 16 connects the inner ends of the score line 14. The cut line 16 includes a pair of generally

parallel cuts

17 and 19 connected by a transversely extending out line 2!). This out line forms a tab 21 designed to overlie one end 12 of the bag B to be secured thereto.

In preferred form an car 22 is provided centrally of the tab or flap 21, this ear being formed by an undulation of the out line Zil. The ear 22 lies beneath the bag or behind the bag, while the notch 23 formed in the flap 21 extends into this flap. A staple 24 may thus extend through the flap 21 on both sides of the car 22 and may extend about the ear 22 so as to hold the flap 21 substantially in alignment with the remainder of the card when the bag is in place.

The opposite end 25 of the card is similarly formed. A pair of aligned

score lines

26 and 27 extend into the card from opposite sides thereof. A U-shaped out line 29 connects the inner ends of the score lines 26 and 27 and forms a fiap 30 designed to overlie the bag end 11. The cut line 29 usually includes

parallel side portions

31 and 32 and a transversely extending out line 33 connecting the ends of the

lines

31 and 32. The transverse out line 33 may be provided with an undulation 34 forming an ear 35 which underlies the bag end 11. The corresponding notch formed in the flap 30 brings into view a portion of the bag end 11. A staple 36 may be inserted through the flap 30, the rear ends of the staple clinching over the ear 35 to fasten the flap 30 substantially in the plane of the remainder of the card.

It is not essential that the

staples

24 and 36 engage both the corresponding flap and ear as the staples extend 3 through the bag and fasten the bag to the

flaps

21 and 30, thereby holding these flaps in substantial alignment. However, the ears do have the advantage of reinforcing the staples and providing a better attachment with the bag.

In Figure 4 of the drawings, I disclose a modified form of card which is indicated in general by the letter C. Only one end of the card C is illustrated as both ends are similar in construction. In the card C, I provide a pair of U-shaped cuts 37 and 39 in side by side relation. The cut 37 includes side portions it; and 41 and a transverse connecting cut 42. The out line 39 similarly includes

side portions

43 and 44 and a transverse connecting portion 45. All of the cut lines 46, 41, 43 and 44 preferably terminate at substantially the same distance from the end 46 of the card.

Aligned score lines

47, 49 and 50 are provided extending transversely of the card. The score line 47 connects the out line 37 to the side edge of the card, while the score line 50 connects the out line 39 to the opposite edge of the card. The score line 40 connects the two out lines 37 and 39. Thus the cut lines form inwardly projecting

tabs

51 and 52 beneath which the major portion of the bag end may be inserted.

The manner of attaching the bag B to the card A or B is illustrated in Figure 3 of the drawings. The ends 15 and 25 of the card A are folded into substantially right angular relation to the center portion 13 of the card. As a result the

flaps

21 and 30 extend substantially vertically. This is usually done over a mandrel or stitching machine body to simplify the operation. The bag B is next dropped onto the body of the card, the ends 11 and 12 lying inwardly of the

flaps

30 and 21. The flaps are then folded back into substantially the plane of the card body and the staples are inserted at the proper location.

The card A or the card C will act to conceal the major portion of the bag ends and to hold the bags stretched tightly over the card surface. The card body may be printed to disclose the contents of the bag or to advertise the contents or other products. The card need be of but slightly greater dimensions than the bag itself in order to function in the manner described. The card C may be made slightly narrower than the card A as the card C is provided with three lines of connection between the central body portion and the end portions.

In accordance with the patent statutes, I have described the principles of construction and operation of my bag support and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that obvious changes may be made within the scope of the following claim without departing from the spirit of my invention.

I claim:

A bag support for supporting a filled tubular bag having fiat sealed ends, the support including a card having transverse cuts therein adjacent the ends thereof defining a central body portion and two end portions hingedly connected to said central body portion along parallel lines of fold, said transverse cuts extending inwardly from said fold lines and forming flap means on said end portions and foldable with said end portions, said cuts also forming an ear extending outwardly from said central body portion at each end thereof dividing the inner ends of each said flap means into two spaced flap portions, the flat ends of the bags overlying said central body portion and said ears and underlying said flap means, and staple means straddling said ears and extending through said spaced flap portions and said flat bag ends, and clinched beneath said ears.
