HEAT SEALABLE PLASTIC MATERIAL BAGS FOR COINS Filed Dec. 29, 1966 SSheets-Sheet IS IN'Eung JOIN! Mingan United States Patent rma ABSTRACT OF THE DISCLOSURE An integral bag for coins is shown which is made entirely of transparent material. The bag includes a continuous first wall and a second wall which is provided with a transverse cut-out portion extending along its entire width. The cut-out portion commences at a point half way along the length of the second wall and terminating at a second point two thirds therealong. The top and bottom transverse edges of the walls and the longitudinal lateral edges thereof are heat sealed to one another so as to define a pair of pockets of unequal size. The larger of the pockets is substantially three times the size of the smaller of the pockets and is designed to retain a plurality of coins and to be folded into the smaller pocket. The coins within the larger pocket prevent displacement of the pockets from their folded position. Indicia are provided on the first wall adjacent the smaller pocket and the cut-out portion.
Description of the invention This invention relates to bags or envelopes and the method of forming them from heat sealable plastic material.
The invention has particular reference to bags or envelopes for use in containing coins more especially for use in banks and like institutions. Bags or envelopes at present in use are normally made from opaque paper material, but it is considered advantageous to be able to provide bags or envelopes for use for containing coins and to have these made of transparent material so that a bank employee can easily ascertain what the bags contain. For example, he can tell whether all the coins contained therein are of the silver or copper type or can tell what are the denominations of the coins contained in the bags or envelopes without having to open them.
It is an object of the present invention to provide an improved bag or envelope more especially to contain coins.
It is another object of the present invention to provide an improved method of making coin-containing bags or envelopes.
According to one aspect of the present invention a bag or envelope for containing coins comprises a length of transparent plastic material whose one side is folded over and heat sealed at its side edges to constitute a first pocket to contain coins and which extends substantially half the height of the bag and the other side is folded over and heat sealed at its side edges to constitute a second smaller pocket and being so arranged that the first pocket may be folded and tucked into the second smaller pocket and retained therein.
According to another aspect of the present invention a method of making bags or envelopes for containing coins includes the step of folding oppositely disposed side edges of a heat scalable transparent plastic material web inwardly in relation to the remainder of the web so that each free side edge ofthe web is folded to overlie the underlying portions of the web, applying heat along transverse lines at longitudinally spaced intervals of the Patented Dec. 19, 1967 ICC Web to seal the folded portions to the underlying portions of the web and cutting the web to divide it into separate bag or envelope-lengths with the folded portions constituting pockets, the larger pocket to contain the coins extending at least about half way across the bag or envelope and the smaller pocket extending substantially one quarter of the distance across the bag or envelope to retain the folded over larger coin-containing pocket.
A bag and a method of making a bag in accordance with the invention will now be described by way of example with reference to the accompanying drawings, wherein FIG. 1 is a perspective view of a bag;
FIG. 2 is a sectional view of a bag being closed;
FIG. 3 is a sectional view of a closed bag containing coins:
FIG. 4 is a diagrammatic view showing layout of the bag making machine; and
FIG. 5 is a series of diagrammatic views showing the steps of making a bag.
Referring to FIGS. l-3 there is shown a bag 1 made of transparent material and which comprises a rear wall 2 and a front wall 10. Front wall 10 is provided with a transverse cut-out portion 11. Cut-out portion 11 commences approximately half way along the length of the bag and continues until approximately two-thirds of the distance along the length of the bag. The top and bottom transverse edges 12 and 13 of walls 2 and 10 are heat sealed to one another. Likewise the longitudinal lateral edges 14 and 15 of walls 2 and 10 are heat sealed to one another. Thus a first pocket 4 which extends substantially half the height of the bag is defined. A receiving pocket 6 into which the first pocket 4 is folded over and retained is also defined.
' The bag is intended to contain five shillings worth of copper coins or five pounds worth of silver coils. It has a total height of 8" with the larger pocket having a depth of 4% and the smaller pocket having a depth of 1%". The bag has a width of 3 /2. When in use the coins are inserted in the larger pocket 4 as shown in FIG. 2 and the smaller pocket of the bag 5 is folded over and the lower end of the pocket 4 containing the coins is inserted in the pocket 6 as shown in FIG. 3 to retain the pocket 4 containing the coins in position in the pocket 6. It will be noted that because the height of the inwardly folded portion 3 is slightly more than half the height of the bag when open the mouth 16 of the pocket 6 receives the lower portion 17 of pocket 4 and retains it in position. The weight of the coins 18 within pocket 4 prevents displacement of the parts. This prevents the coins falling out of the bag.
The bags are preferably made from 200 gauge high impact low density polyethylene. However, gauge or gauge polyethylene may be suitable. Likewise transparent polypropylene may be employed.
A method of making the bag shown in FIGS. l-3 in accordance with the invention is illustrated in FIGS. 4 and 5. The bag is made from a continuous web of tubular transparent plastics material of 150 gauge high impact transparent polyethylene. This tubular web 7 is printed on the front and rear faces overall at 8 (FIG. 5). This printing 8 may take the form of an indication of the bank which is to use the bags when manufactured as well as some indication of the value and kind of coins to be contained in the bag (FIG. 1). This web is fed from a reel past a pair of web guide rollers 9 and a pre-slitter roller 10. The tubular web is then fed past a top slitter mechanism 11 and a bottom slitter mechanism 12 so that the tubular web is divided into two continuous folded webs as shown at 13 in FIG. 5. It will be apparent that the tubular web is divided at a distance from each side of the tube corresponding to the depth of the first pocket 4 and the remaining length of the rear wall extends to the total length of the rear walltogether with the width of the smaller pocket 6. The two webs then pass over capstan drive rollers 14 and over sets of compensating rollers 15. At the outfeed side of the compensating rollers 15 the Webs are divided and fed over respective folding rollers 16 and respective folding mechanisms 17 whereat the part of the bag constituting the smaller folded portion is folded as shown at 18 in FIG. 5. The webs are then merged together as shown at 19 (FIG. to pass around a. further set of rollers 20 and subsequently the smaller folded portion 5 is folded close to the back wall of the bag as shown at 21 (FIG. 5) to form the pocket 6. The two webs then pass over respective rollers 22 and 23 of which roller 23 acts to compensate for any discrepancies in the feeding of the two webs and thereby serves to synchronise the feeding of the two webs by taking up any slack in its webs. The two webs are then passed between draw rollers 24 to a heat sealing and cutting mechanism 25 Whereat the bags are sealed and cut at their side edges into bag lengths as shown in FIG. 1.
It will be apparent that although the invention has been described by way of a method of making bags employing the holding of a tube in two separate bag lengths, the bag can be made from a single web of transparent plastic material by folding the single width of web to form the required pockets and subsequently sealing and severing the folded web into bag lengths.
What I claim is:
1. An integral bag made entirely of transparent material including a continuous first wall and a second wall provided with a transverse cut-out portion extending along the entire width of said second wall, said cut-out portion commencing substantially at a point halfway along the length of said second wall and terminating at about two thirds along the length thereof, the top and bottom transverse edges and the longitudinal lateral edges of said walls being heat sealed to one another so as to define a pair of spaced pockets of unequal size therewithin, the larger of said pockets being substantially three times the size of the smaller of said pockets, said larger pocket adapted to retain a plurality of coins and to be folded into the smaller of said pockets, the coins within said larger pocket preventing displacement of said pockets from their folded position 2. An integral bag as defined in claim 1 including indicia upon said first wall adjacent said smaller pocket.
3. An integral bag as defined in claim 2 said indicia being also adjacent said cut-out portion.
