Definitions
- This invention relates to a synthetic resin bag which can be hand-carried with purchased goods received therein.
- a shopper picks up goods he or she wants to buy, puts them in a basket or cart of the store, brings the basket or cart to a cash counter, and puts the basket or the goods on the register counter.
- the cashier picks up the purchased goods from the basket one by one to scan the bar-codes, and transfers them in another basket, and, when all this work is done, hands one or more plastic shopping bag to the shopper.
- the shopper picks up the basket filled with the purchased goods and brings it to a separate table or counter, where the shopper puts the purchased goods into the plastic shopping bag or bags.
- self-service style is adopted.
- a cashier and another packaging assistant are stationed at each cash register counter.
- the packaging assistant selects a suitable bag or bags, puts the goods purchased by each shopper into the selected bag or bags, seals the bag and hands it to the shopper.
- any crooked shopper is discouraged from coming back into the store, sneak additional goods into the bag containing goods of which the payment has been finished, and leave the store, bypassing the cashier by virtue of the bag provided by the cashier and serving as evidence that the payment was already made.
- this is also a less conspicuous way to prevent or at least discourage shoplifting.
- Typical plastic shopping bags used in e.g. supermarkets to put purchased goods are polyethylene bags having grip portions at both sides on top. Numerous such bags are folded flat and stacked near each cashier. If a cashier also serves as a packaging assistant, a plurality of shelves for keeping bags of different size from the bags in the other shelves are arranged around the cashier on a single horizontal plane so that the cashier can easily pull out a bag from any shelf. Because the shelves are arranged on a single horizontal plane, they take up a large space. When the cashier pulls out the topmost bag from a selected shelf in an irritated hurried manner, the remaining bags tend to be ruffled and scatter. This makes it more difficult to pull out a single bag neatly next time.
- the cashier After pulling out a bag, the cashier has to open the bag using both hands. Thus, the cashier cannot do any other jobs while opening the bag. Moreover, in order to keep the mouth of the bag open, the casher has to keep holding the bag with one hand. This extremely lowers the efficiency of the cashier.
- An object of the present invention is to provide a bag of the abovementioned type which can be hung on a hanger device, which can be opened with a single hand, which can keep its mouth open without the need of a support by a hand, and which can be removed from the hanger device without scattering the remaining bags.
- a plastic shopping bag for receiving purchased goods, the bag being formed of a synthetic resin and comprising a front sheet, a back sheet, and pleats each connecting one side edge of the front sheet to a corresponding side edge of the back sheet, each of the pleats being folded inwardly such that a fold line is formed inside of the respective side edges of the front and back sheets, the front and back sheets and the pleats have their bottom edges welded together to close the bottom of the bag, the bag further including upwardly protruding handles at both ends of a top edge of the bag, each of the front and back sheets having a tongue portion formed on the top edge thereof between the handles, each of the tongues being formed with a first hole, each of the front and back sheets being formed two second holes for hanging up the bag itself, and further formed with a perpendicular cutting guide extending from each of the second holes to the top edge thereof, and a perforated cutting guide extending over the entire width of the tongue below the first hole.
- each of the front and back sheets is formed with a cut below a line connecting the second holes, the cut defining a tab.
- Each of the tabs is preferably formed with a finger catch that engages a finger and prevents slip of the finger on the tab.
- the handles are each formed with a hole through which a finger can be inserted to grab the handle.
- the bag of this invention may have a small semi-circular puller-tab shaped out by a half-moon slit located straight down from the hole in the tongue and just a little down from the invisible straight horizontal line extending between the two second holes.
- This puller-tab may have a slit or hole in the center with which the frontmost sheet alone can be easily singled out by just rubbing together the tips of the thumb and the index finger through the slit or the hole.
- the plastic shopping bag of this invention is made of polyethylene tubular material which is folded flat with two pleats with the lateral sides held between the two sheets, the frontal one and the rear one, cut to a required length and both the bottom side end and the pleat ends are welded together to provide tightly sealed bottom.
- handles are shaped out at the top by cutting into either of the front sheet and the rear sheet on both their inner sides leaving their outer parts left uncut.
- the handles are comprised of four sheets, namely, the front sheet, back sheet, pleated part now into two sheets.
- the handle parts are welded at the top ends and the cutting is made to go beyond the pleated end so that the handles will form a hollow loop so that the hand can go through for gripping.
- both the front sheet and the back sheet have on their central top area an upward protrusion or a tongue with the broader neck part extending into a narrower head part with an intermittent severing line made at the top area of the broader neck part.
- puller tab mentioned above is made inside the U-shape incision given to both the front sheet and the back sheet.
- This puller tab has a hole or a slit of various shapes.
- the bag 1 is formed of a synthetic resin, and comprises a front sheet 2, a back sheet 3 and inwardly folded pleats 4 connecting the side edges of the sheet 2 to the corresponding side edges of the sheet 3.
- the sheets 2 and 3 and the pleats 4 are welded together along their bottom edges as shown at 5 to close the bottom of the bag 1.
- the bag 1 has handles 6 each protruding upwardly from one end of the top edge of the bag. Between the handles 6, the top edges of the sheets 2 and 3 are not welded together to form a top opening of the bag 1 through which purchased goods can be put into the bag 1. In the middle of the top edge, each of the sheets 2 and 3 has an upwardly protruding tongue 8 that overlaps with the tongue 8 of the other of the sheets 2 and 3.
- each of the sheets 2 and 3 is formed with a pair of holes 9 aligned with the corresponding holes 9 of the other of the sheets 2 and 3.
- the tongues 8 of the sheets 2 and 3 are formed with a through hole 10 on its top area.
- a cutting line or guide 11 such as a perforation line is formed in each of the sheets 2 and 3 so as to extend from each hole 9 to the top edge of the sheet 2 or 3.
- a horizontal, cutting line or guide 12 such as a perforation line extends over the entire width of each tongue 8.
- the holes 10 are located above the holes 9 so that the holes 9 and 10 formed in each of the sheets 2 and 3 configure three vertices of an isosceles triangle.
- a plurality of such bags as described above are made from a thin tubular material of polyethylene, e.g., in the following manner: First, a thin synthetic resin tube is pressed with both sides folded inwardly in V shape as deeply as desired so that the sheets 2 and 3 and the pleats 4 are stacked one over another as shown in Fig. 1B. The tube is then cut to a plurality of portions having a desired length so that each portion comprises the front sheet 2, the back sheet 3 and the pleats 4. The sheets 2 and 3 and the pleats 4 are thereafter welded together along the bottom edges thereof to form the bottom of the bag.
- each handle 6 comprises a total of four overlapped sheet portions, i.e. a portion of the front sheet 2, a portion of the back sheet 3 and folded portions of each pleat 4.
- the four sheet portions have their top edges welded together as shown at 14.
- the portions of the pleats 4 forming the handles 6 are cut along their inner fold lines to form holes 15 through which a hand can pass to hold the handles 6.
- Each tongue 8 comprises a lower wide portion 8a, which connects to the top edge of the sheet 2 or 3, and an upper narrow portion 8b connecting to the wide portion 8a.
- the hole 10 is formed in the narrow portion 8a near its top end.
- the cutting line or guide 12 extends over the entire width of the wide portion 8a near its top end.
- a U-shaped cut 16 is formed to define a tab portion 17 in which a finger catch 18 to help to catch one single topmost/foremost tab in between the finger tips is formed.
- the finger catch 18 makes it easier for anyone to pick up only the topmost/foremost one of the tabs 17 by rubbing the tip of the thumb against that of the index finger passed through the catch 18 with a haphazardly picked up top layer part of the tabs held in between them to make sure that the mouth of only the first bag gets opened.
- the finger catch 18 may be a punched hole, a cut or a slit. Specifically, the finger catch 18 may be a vertical slit as shown in Fig. 6A, a horizontal slit as shown in Fig. 6B, or a circular hole as shown in Fig. 6C.
- the finger catch 18 may also be shaped in any other way. For example, it may be a vertical, horizontal or oblique groove, an oblique slit, an X-, V- or U-shaped slit, or a hole in the shape of a flower, a heart, spade, diamond or club of a playing cards, a company symbol or any other device. If the finger catch is a groove or a slit, it preferably terminates with circular holes 18a as shown to prevent the end of the slit from tearing further from the end of such a groove or slit. When a fingertip is thrusted into it to widen it, similar circular holes 18a are also preferably formed at both ends of the U-shaped cut 16 for the same effect against the pull by the tab 17.
- Cutouts 19 are preferably formed along the top edge of each of the sheets 2 and 3 on both sides of the tongue 8 so that when the front sheet 2 is pulled to open the mouth 7 of the bag, the tongue 8 of the sheet 2 more readily separates from the tongue 8 of the back sheet 3 and thus the mouth 7 of the bag 1 can be more readily opened and wider than when no such cutouts are made. This of course makes it easier to put purchased goods.
- a plurality of such bags are hung on three rods 21 and 22 (Fig. 4) by inserting the rods 21 into the holes 9 and the rod 22 into the holes 10.
- Each handle 6 is formed with a hole 20 near its top end, and a discontinuous cut-line 20a extending from the hole 20 to the outer edge of the handle.
- an elastic ring 26 is inserted in the holes 20 of the handles 6 on each side of the bags. The elastic rings 26 prevent the handles 6 of each bag from falling into the bag when the mouth 7 is opened, and also keep the mouth 7 wide open, so that large items can be easily bagged.
- the three rods 21 and 22 and the elastic rings 26 are elements of a bag hanger device A.
- the rod 22 is provided in the rear of the rods 21.
- the hanger device A further includes a support plate 23 on or through which are arranged the rods 21 and 22 to support upper portions of the bags as shown in Fig. 5, and another support plate 24 for supporting the bottoms of the bags.
- Each of the rods 21 and 22 is a metallic wire comprising a horizontal portion and a vertical portion extending vertically upwardly from one end of the horizontal portion. The distances between the rods 21 and 22 and the position of the support plate 24 are adjusted according to the distances between the holes 9 and 10 and the vertical dimension of the bags to be hung on the hanger device A.
- the three rods 21 and 22, which are to be inserted in the respective holes 9 and 10, are supported on the support plate 23 (Fig. 5) so as to be arranged on the respective vertices of an isosceles triangle.
- the support plate 23 is also substantially in the shape of an isosceles triangle with the rods 21 and 22 arranged near their respective apexes.
- the support plate 23 has a front edge which is located slightly in front of the line connecting the rods 21 (see Figs. 3 and 4).
- each bag is provided such that their top edges will substantially erect near-horizontally from the front edge of the support plate 23 when the bag is hung on the rods 21 and 22 by inserting the rods 21 and 22 into the respective holes 9 and 10.
- the portion of each bag above the horizontal line including the top edges of the tabs 17 rests on the support plate 23 with the remaining portion hanging from the front edge of the support plate 23.
- each bag is bent downward along the top edges of the tabs 17, the tabs tend to erect near-horizontally so as to be substantially flush with the top surface of the support plate 23 as clearly shown in Figs. 3 and 4.
- the tabs 17 can thus be easily picked with two fingers, the thumb and the index finger for example.
- the hanger device A may be a permanently fixed type in which both the rods 21 and 22 and the support plate 24 are mounted to a vertical, stationary wall 25. While not shown, the hanger device A may be of a type disclosed in (unexamined) JP patent publication 2001-315726, which was filed by the applicant of this invention. That is, the hanger device disclosed in this publication comprises a base, a vertical pillar supported on the base, a rotary cylinder rotatably mounted on the pillar, and a plurality of bag-engaging frames or plates mounted to the outer surface of the rotary cylinder and each carrying a bag-hanging member and a support plate at its upper and lower portions according to the size of bags to be hung.
- the hanger device A is placed near a cashier counter loaded with a stack of a large number of the bags according to this invention hang thereon by inserting the rods 21 and 22 into the holes 9 and 10 of the respective bags with their upper portions supported on the support plate 23 and their bottoms supported on the support plate 24.
- elastic rings 26 are inserted in the holes 20 formed in the respective handles 6 of the bags near their top ends with the handles 6 bent forwardly.
- the cashier picks only the front tab 17 with fingertips. But the front and rear tabs 17 are often stuck together, so that the cashier may pick both the front and rear tabs 17 randomly with the fingertips pushed into the central opening of the tabs 17.
- the finger catches 18 of the top tab 17 comes off the other under it, so that the two fingers are separated from each other by the tabs 17.
- the cashier can thus easily recognize that the forefront one of the tabs 17 is now singled out, because if only the front tab 17 is held between the two fingertips, the two fingertips are fully in direct contact with each other at the area where there is the opening of the finger catch 18.
- the cashier detects that both the forefront and rear tabs 17 are held between the two fingertips, he or she pulls it toward them in opposite directions to each other while either of the fingertips is engaged in the finger catches 18 to separate them from each other until the rear tab 17 disengages from the fingers. With only the front tab 17 held between the fingers, the cashier pulls it. When the front tab 17 is pulled, the front sheet 2 only will be torn along the cut-lines 11 and 12, so that the front sheet 2 will disengage from the rods 21 with the narrow portion 8b of the tongue 8 still caught by the rod 22.
- the holes 15 formed in the handles 6 also expand as shown in Fig. 5. Fingers or a hand can thus be easily inserted into the holes 15 to grab the handles 6 and lift up the bag.
- the mouth 7 of the bag can be easily opened wide with two fingers of one hand.
- the cashier inserts fingers of both hands into the holes 15 to grab the handles 6, and pulls the handles 6 with a sufficient force such that the back sheet 3 is torn first along the cut-line 12 and then along the cut-lines 11.
- the bag is further pulled, it is torn along the cut-line 20a.
- the cashier then seals the mouth of the bag with e.g. adhesive tape and hands the bag to the customer.
- the mouth 7 of the bag 1 can be opened wide.
- the cashier can use the other hand to pick up goods and scan the bar-codes. Once the mouth 7 is opened, it remains open on its own. The cashier can thus use one hand to pick up goods and scan the bar-code, and the other hand to put goods into the bag.
- the narrow portions 8b of the tongues 8 will be still held by the rod 22, so that they will never scatter around. This eliminates the need to frequently clean the floor to remove debris of bags.

Description
- This invention relates to a synthetic resin bag which can be hand-carried with purchased goods received therein.
- In a typical Japanese supermarket, drugstore or any other large-scale store, a shopper picks up goods he or she wants to buy, puts them in a basket or cart of the store, brings the basket or cart to a cash counter, and puts the basket or the goods on the register counter. The cashier picks up the purchased goods from the basket one by one to scan the bar-codes, and transfers them in another basket, and, when all this work is done, hands one or more plastic shopping bag to the shopper. After payment, the shopper picks up the basket filled with the purchased goods and brings it to a separate table or counter, where the shopper puts the purchased goods into the plastic shopping bag or bags. Namely, self-service style is adopted.
- In some stores, a cashier and another packaging assistant are stationed at each cash register counter. The packaging assistant selects a suitable bag or bags, puts the goods purchased by each shopper into the selected bag or bags, seals the bag and hands it to the shopper.
- With this new system, it is possible to omit separate tables or counters on which shoppers put purchased goods into bags. This saves the facility cost and space and saves the shopper from the trouble of bagging on their own all the goods they purchased.
- Also, since the bags are sealed by the backaging assistant, any crooked shopper is discouraged from coming back into the store, sneak additional goods into the bag containing goods of which the payment has been finished, and leave the store, bypassing the cashier by virtue of the bag provided by the cashier and serving as evidence that the payment was already made. Thus, this is also a less conspicuous way to prevent or at least discourage shoplifting.
- But stationing two people at each casher's counter is of course uneconomical from the viewpoint of the labor cost.
- One way to save the labor cost is for a cashier to do the packaging assistant's job. But this doubles the cashier's job, thus putting an excessive burden on the cashier.
- Typical plastic shopping bags used in e.g. supermarkets to put purchased goods are polyethylene bags having grip portions at both sides on top. Numerous such bags are folded flat and stacked near each cashier. If a cashier also serves as a packaging assistant, a plurality of shelves for keeping bags of different size from the bags in the other shelves are arranged around the cashier on a single horizontal plane so that the cashier can easily pull out a bag from any shelf. Because the shelves are arranged on a single horizontal plane, they take up a large space. When the cashier pulls out the topmost bag from a selected shelf in an irritated hurried manner, the remaining bags tend to be ruffled and scatter. This makes it more difficult to pull out a single bag neatly next time.
- After pulling out a bag, the cashier has to open the bag using both hands. Thus, the cashier cannot do any other jobs while opening the bag. Moreover, in order to keep the mouth of the bag open, the casher has to keep holding the bag with one hand. This extremely lowers the efficiency of the cashier.
- An object of the present invention is to provide a bag of the abovementioned type which can be hung on a hanger device, which can be opened with a single hand, which can keep its mouth open without the need of a support by a hand, and which can be removed from the hanger device without scattering the remaining bags.
- According to this invention, there is provided a plastic shopping bag for receiving purchased goods, the bag being formed of a synthetic resin and comprising a front sheet, a back sheet, and pleats each connecting one side edge of the front sheet to a corresponding side edge of the back sheet, each of the pleats being folded inwardly such that a fold line is formed inside of the respective side edges of the front and back sheets, the front and back sheets and the pleats have their bottom edges welded together to close the bottom of the bag, the bag further including upwardly protruding handles at both ends of a top edge of the bag, each of the front and back sheets having a tongue portion formed on the top edge thereof between the handles, each of the tongues being formed with a first hole, each of the front and back sheets being formed two second holes for hanging up the bag itself, and further formed with a perpendicular cutting guide extending from each of the second holes to the top edge thereof, and a perforated cutting guide extending over the entire width of the tongue below the first hole.
- Preferably, each of the front and back sheets is formed with a cut below a line connecting the second holes, the cut defining a tab. Each of the tabs is preferably formed with a finger catch that engages a finger and prevents slip of the finger on the tab.
- Preferably, the handles are each formed with a hole through which a finger can be inserted to grab the handle.
- The bag of this invention may have a small semi-circular puller-tab shaped out by a half-moon slit located straight down from the hole in the tongue and just a little down from the invisible straight horizontal line extending between the two second holes. This puller-tab may have a slit or hole in the center with which the frontmost sheet alone can be easily singled out by just rubbing together the tips of the thumb and the index finger through the slit or the hole.
- This singling out of the frontmost sheet by the rubbing of the two fingertips makes it possible to open the mouth of the foremost one from all the other bags kept hung behind it on the hanger device. Besides this , a hole may be made near the top edge of each of the handle parts to keep the handles themselves aloof from the bag's mouth.
- The plastic shopping bag of this invention is made of polyethylene tubular material which is folded flat with two pleats with the lateral sides held between the two sheets, the frontal one and the rear one, cut to a required length and both the bottom side end and the pleat ends are welded together to provide tightly sealed bottom.
- Besides, two handles are shaped out at the top by cutting into either of the front sheet and the rear sheet on both their inner sides leaving their outer parts left uncut. Now the handles are comprised of four sheets, namely, the front sheet, back sheet, pleated part now into two sheets. The handle parts are welded at the top ends and the cutting is made to go beyond the pleated end so that the handles will form a hollow loop so that the hand can go through for gripping.
- Still besides, both the front sheet and the back sheet have on their central top area an upward protrusion or a tongue with the broader neck part extending into a narrower head part with an intermittent severing line made at the top area of the broader neck part.
- Further, the puller tab mentioned above is made inside the U-shape incision given to both the front sheet and the back sheet. This puller tab has a hole or a slit of various shapes.
- Other features and objects of this invention will become apparent from the following description when taken with reference to the accompanying drawings, in which:
- Fig. 1A is a front view of the bag according to this invention;
- Fig. 1B is a cross-section taken along line B-B of Fig. 1A;
- Fig. 2 is a partial perspective view of the bag of Fig. 1A, showing its upper portion;
- Fig. 3 is a partial perspective view of the bag of Fig. 1A, showing how it is hung on a hanger device;
- Fig. 4 is a view similar to Fig. 3 when the mouth is opened.
- Fig. 5 is a side view of the bag of Fig. 1A when it is hung on a hanger device with its mouth open; and
- Figs. 6A to 6C show bags of the present invention formed with different finger catches in the puller tab portions.
-
- Referring to the drawings, the
bag 1 according to this invention is formed of a synthetic resin, and comprises afront sheet 2, aback sheet 3 and inwardly foldedpleats 4 connecting the side edges of thesheet 2 to the corresponding side edges of thesheet 3. Thesheets pleats 4 are welded together along their bottom edges as shown at 5 to close the bottom of thebag 1. - The
bag 1 has handles 6 each protruding upwardly from one end of the top edge of the bag. Between thehandles 6, the top edges of thesheets bag 1 through which purchased goods can be put into thebag 1. In the middle of the top edge, each of thesheets tongue 8 that overlaps with thetongue 8 of the other of thesheets - Near the top edge at both sides and adjacent to the inner end of the two
pleats 4, each of thesheets holes 9 aligned with thecorresponding holes 9 of the other of thesheets tongues 8 of thesheets hole 10 on its top area. A cutting line or guide 11 such as a perforation line is formed in each of thesheets hole 9 to the top edge of thesheet hole 10, a horizontal, cutting line or guide 12 such as a perforation line extends over the entire width of eachtongue 8. - The
holes 10 are located above theholes 9 so that theholes sheets - A plurality of such bags as described above are made from a thin tubular material of polyethylene, e.g., in the following manner:
First, a thin synthetic resin tube is pressed with both sides folded inwardly in V shape as deeply as desired so that thesheets pleats 4 are stacked one over another as shown in Fig. 1B. The tube is then cut to a plurality of portions having a desired length so that each portion comprises thefront sheet 2, theback sheet 3 and thepleats 4. Thesheets pleats 4 are thereafter welded together along the bottom edges thereof to form the bottom of the bag. - The
handles 6 and thetongues 8 are formed by cutting out the top edge of thebag 1 substantially in the shape of an upended M as shown at 13. As shown in Fig. 2, eachhandle 6 comprises a total of four overlapped sheet portions, i.e. a portion of thefront sheet 2, a portion of theback sheet 3 and folded portions of eachpleat 4. The four sheet portions have their top edges welded together as shown at 14. As shown in Figs. 4 and 5, when the top edge of the bag is cut out substantially in the shape of an upended M, the portions of thepleats 4 forming thehandles 6 are cut along their inner fold lines to formholes 15 through which a hand can pass to hold thehandles 6. - Each
tongue 8 comprises a lowerwide portion 8a, which connects to the top edge of thesheet narrow portion 8b connecting to thewide portion 8a. Thehole 10 is formed in thenarrow portion 8a near its top end. The cutting line or guide 12 extends over the entire width of thewide portion 8a near its top end. - In each of the
sheets holes 9, aU-shaped cut 16 is formed to define atab portion 17 in which afinger catch 18 to help to catch one single topmost/foremost tab in between the finger tips is formed. - The
finger catch 18 makes it easier for anyone to pick up only the topmost/foremost one of thetabs 17 by rubbing the tip of the thumb against that of the index finger passed through thecatch 18 with a haphazardly picked up top layer part of the tabs held in between them to make sure that the mouth of only the first bag gets opened. - The
finger catch 18 may be a punched hole, a cut or a slit. Specifically, thefinger catch 18 may be a vertical slit as shown in Fig. 6A, a horizontal slit as shown in Fig. 6B, or a circular hole as shown in Fig. 6C. - The
finger catch 18 may also be shaped in any other way. For example, it may be a vertical, horizontal or oblique groove, an oblique slit, an X-, V- or U-shaped slit, or a hole in the shape of a flower, a heart, spade, diamond or club of a playing cards, a company symbol or any other device. If the finger catch is a groove or a slit, it preferably terminates withcircular holes 18a as shown to prevent the end of the slit from tearing further from the end of such a groove or slit. When a fingertip is thrusted into it to widen it, similarcircular holes 18a are also preferably formed at both ends of theU-shaped cut 16 for the same effect against the pull by thetab 17. -
Cutouts 19 are preferably formed along the top edge of each of thesheets tongue 8 so that when thefront sheet 2 is pulled to open themouth 7 of the bag, thetongue 8 of thesheet 2 more readily separates from thetongue 8 of theback sheet 3 and thus themouth 7 of thebag 1 can be more readily opened and wider than when no such cutouts are made. This of course makes it easier to put purchased goods. - A plurality of such bags are hung on three
rods 21 and 22 (Fig. 4) by inserting therods 21 into theholes 9 and therod 22 into theholes 10. Eachhandle 6 is formed with ahole 20 near its top end, and a discontinuous cut-line 20a extending from thehole 20 to the outer edge of the handle. With a plurality of bags according to the present invention hung on the three rods, anelastic ring 26 is inserted in theholes 20 of thehandles 6 on each side of the bags. The elastic rings 26 prevent thehandles 6 of each bag from falling into the bag when themouth 7 is opened, and also keep themouth 7 wide open, so that large items can be easily bagged. - With a plurality of bags hung on the three
rods elastic rings 26, thetab 17 of one of thesheets mouth 7 to bag purchased goods. - As shown in Figs. 3-5, the three
rods elastic rings 26 are elements of a bag hanger device A. As shown, therod 22 is provided in the rear of therods 21. The hanger device A further includes asupport plate 23 on or through which are arranged therods support plate 24 for supporting the bottoms of the bags. - Each of the
rods rods support plate 24 are adjusted according to the distances between theholes - Since the
holes rods respective holes support plate 23 is also substantially in the shape of an isosceles triangle with therods support plate 23 has a front edge which is located slightly in front of the line connecting the rods 21 (see Figs. 3 and 4). Thetab portions 17 of each bag are provided such that their top edges will substantially erect near-horizontally from the front edge of thesupport plate 23 when the bag is hung on therods rods respective holes tabs 17 rests on thesupport plate 23 with the remaining portion hanging from the front edge of thesupport plate 23. - In this state, because each bag is bent downward along the top edges of the
tabs 17, the tabs tend to erect near-horizontally so as to be substantially flush with the top surface of thesupport plate 23 as clearly shown in Figs. 3 and 4. Thetabs 17 can thus be easily picked with two fingers, the thumb and the index finger for example. - As shown in Fig. 5, the hanger device A may be a permanently fixed type in which both the
rods support plate 24 are mounted to a vertical,stationary wall 25. While not shown, the hanger device A may be of a type disclosed in (unexamined) JP patent publication 2001-315726, which was filed by the applicant of this invention. That is, the hanger device disclosed in this publication comprises a base, a vertical pillar supported on the base, a rotary cylinder rotatably mounted on the pillar, and a plurality of bag-engaging frames or plates mounted to the outer surface of the rotary cylinder and each carrying a bag-hanging member and a support plate at its upper and lower portions according to the size of bags to be hung. - The hanger device A is placed near a cashier counter loaded with a stack of a large number of the bags according to this invention hang thereon by inserting the
rods holes support plate 23 and their bottoms supported on thesupport plate 24. - As shown in Figs. 3 and 4,
elastic rings 26 are inserted in theholes 20 formed in therespective handles 6 of the bags near their top ends with thehandles 6 bent forwardly. - In this state, in order to put purchased goods into the forefront bag, the cashier picks only the
front tab 17 with fingertips. But the front andrear tabs 17 are often stuck together, so that the cashier may pick both the front andrear tabs 17 randomly with the fingertips pushed into the central opening of thetabs 17. By simply rubbing the fingertips against each other with thetabs 17 squeezed in between them, the finger catches 18 of thetop tab 17 comes off the other under it, so that the two fingers are separated from each other by thetabs 17. The cashier can thus easily recognize that the forefront one of thetabs 17 is now singled out, because if only thefront tab 17 is held between the two fingertips, the two fingertips are fully in direct contact with each other at the area where there is the opening of thefinger catch 18. If the cashier detects that both the forefront andrear tabs 17 are held between the two fingertips, he or she pulls it toward them in opposite directions to each other while either of the fingertips is engaged in the finger catches 18 to separate them from each other until therear tab 17 disengages from the fingers. With only thefront tab 17 held between the fingers, the cashier pulls it. When thefront tab 17 is pulled, thefront sheet 2 only will be torn along the cut-lines front sheet 2 will disengage from therods 21 with thenarrow portion 8b of thetongue 8 still caught by therod 22. - When only the
front tab 17 is pulled in the above-described manner, no tension is applied to theback sheet 3, so that theback sheet 3 is never affected and remains engaged by therods front sheet 2 now separated from theback sheet 3. Themouth 7 of thebag 1 is thus opened wide as shown in Figs. 4 and 5. - When the
mouth 7 is opened wide, theholes 15 formed in thehandles 6 also expand as shown in Fig. 5. Fingers or a hand can thus be easily inserted into theholes 15 to grab thehandles 6 and lift up the bag. - As will be apparent from the above description, the
mouth 7 of the bag can be easily opened wide with two fingers of one hand. - With the mouth of the bag wide open, the
elastic rings 26 keep thehandles 6 bent as shown in Fig. 4, thus preventing thehandles 6 from dropping into themouth 7 of the bag. Thus, even large items can be bagged easily. - With the mouth of a bag wide open, a cashier picks up, one by one, the goods the customer has selected, scans them, and immediately puts them into the bag in regular and rapid sequence. Since the
bag 1 has its bottom supported on thesupport plate 24, no tension is applied to theback sheet 3 no matter how heavy the contents of the bag are. Theback sheet 3 is thus stably kept hanging from therods - When all the purchases have been bagged and the payment has been made, the cashier inserts fingers of both hands into the
holes 15 to grab thehandles 6, and pulls thehandles 6 with a sufficient force such that theback sheet 3 is torn first along the cut-line 12 and then along the cut-lines 11. When the bag is further pulled, it is torn along the cut-line 20a. Now thebag 1 is free from therods - As described above, simply by pulling the
tab 17 of thefront sheet 2 of abag 1 hanging from therods mouth 7 of thebag 1 can be opened wide. Thus, while opening the mouth of a bag with one hand, the cashier can use the other hand to pick up goods and scan the bar-codes. Once themouth 7 is opened, it remains open on its own. The cashier can thus use one hand to pick up goods and scan the bar-code, and the other hand to put goods into the bag. After bags have been removed from therods narrow portions 8b of thetongues 8 will be still held by therod 22, so that they will never scatter around. This eliminates the need to frequently clean the floor to remove debris of bags. - Since numerous bags are hung from the
rods
