PAPER-BAG-SEALIN G MEANS.

Application filed June 17, 1924. Serial No. 720,693.

This invention relates to improved means for sealing paper bags and the novel features of the invention will appear from the detailed description taken in connection with the accompanying sheet of drawings forming part of this specification.

In the drawings, Fig. 1 is a perspective view of an ordinary paper bag provided with my improved sealing means.

Fig. 2 is a perspective view of a bag sealed by the sealing means shown in Fig. 1.

Fig. 3 is a perspective view similar to Fig. 1 showing a slightly different form of sealing means; and

Fig. 4 is a bag scaled up by the means shown in Fig. 3. V In the drawings, numeral 1 indicates a paper bag of standard form to the bottom of which is secured as at 2 a ribbon or tape 3 extending along one side of the bag and se cured at its top end to the top of the bag as indicated generally by numeral 4. The tape or ribbon 3 is provided with two parallelly extending rows of perforations 5 and with a transversely extending line of perforations 6 near the top of the bag. The middle portion of the tape 3 between the two rows of perforations 5 is indicated at 7 and theside parts of the tape by numeral 8. The tape or ribbon 3 is gummed on its side adjacent the wall of the bag and is secured to the top of the bag at 4 by means of the gum or adhesive 0n the tape. The tape is not secured to the bag intermediate its ,points of securement at 2 and 4.

When the bag is to be closed. the side strips 8 are detached from the main body of the tape on the line 6 and the top of the bag folded under as shown in Fig. 2. Thereafter the gummed side of the strips 8 are moistened and secured to the opposite wall of the bag as is clearly shown in Fig. 2. If desired. the stri or intermediate portion 7 of the tape can be severed on the line 6, the side strips remaining attached. It will be understood that if the middle strip 7 is to be used for sealing the bag it will be moistened on its gummed side and secured to the opposite wall of the bag the same as would be the case if the strips 8 were used.

In the form of sealing means shown in Fig. 3 the tape or ribbon 3 is secured to the lower edge of the side wall of the ba by means of the adhesive on the tape an the top of the tape is secured to the top of the bag as indicated at 4 by the adhesive on the tape. In this form of the invention as in the form already described the tape is not secured to the bag intermediate its points of securement at either end. The "tape in the form of the invention shown in Fig. 3 is provided with a longitudinally extending row of perforations 9 and a transversely extending row of perforations 6 adjacent the top of the tape. The row of perforations 9 divides the strips into two parts 10 and 11, a pair of tapes being provided in this form of the invention by reason of the fact that the ribbon is narrower than in the form shown in Fig. 1. When the bag is to be sealed, one of the strips 10 or 11 is detached from the top of thebag on the line 10 after which the top of the bag is folded under as shown in Fig. 4 and the detached ends or strips 10 moistened and secured to the side Walls of the bag.

By securing the tape 3 only at its ends to the top and bottom of the bag and allowing the user to detach the tape or portion thereof from the top of the bag. a very convenient arrangement of securing means is obtained. When the strip or tape 3 is left unattached as heretoforedone there is great likelihood of the tape becoming torn or loosened from the bag. According to my invention there are no loose ends connected with the securing tape and consequently there is no danger of the tape becoming torn or damaged but the same is always in condition ready for use. Furthermore. by securing the tape only at its bottom end to the bottom of the bag or adiacent the bottom thereof the entire strip can be detached from the top of the bag and wrapped around the bag and sealed thereto by moistening the same.

Another advantage of my invention is that the tape canbe' readily secured to the bag in the process of manufacture inasmuch as the strip is only of such length as to extend from the top of the bag to the bottom thereof.

The bag is preferably provided with marked graduations indicating fractional capacities of the bag. This permits ready filling of the bag in fractional. amounts, as will be readily understood.

What I claim is:

The combination with a flexible receptacle having one end open and adapted to be fold: ed upon itself to close the same, of a longi tudinal flexible strip extending the entire length of the receptacle and having both ends permanently attached thereto, the strip being provided with parallel Weakened lines and a transverse weakened line, the latter being disposed in close proximity to the open end of the receptacle and adapt ed to be torn transversely to free one end of the strip, the strip being further adapted to be torn along the parallel weakened lines to provide a pair of parallel securing tapes adapted to be aflixed to one Wall of the receptacle, when the latter has been filled with merchandise and closed.

In testimony whereof I aflix my signature.

CASIAH SAPP.
