With the zipper 5, the upper portion 14 can be opened and closed, and the upper portion 14 can be wide open. Further, at least one heat fusable plastic sheet may be put between the films 11 and 12, so that a plural number of chambers can be formed. Also, the films 11 and 12 may be fused along a vertical line, so that a plural number of chambers can be formed.
Description
- The present invention relates to a plastic zipper bag, and more particularly to a plastic bag with a zipper on an inner surface of an upper opening portion, the zipper having a groove and a protrusion engaging with and disengaging from each other.
- Conventionally, various kinds of plastic bags with zippers, each having a groove and a protrusion engaging with and disengaging from each other, at their upper opening portions in the inner surfaces have been provided.
-
FIGS. 13 a, 13 b and 13 c show a typical type of these plastic bags. AsFIGS. 13 a, 13 b and 13 c show, both sides of twoplastic films zipper 5 is provided at an upper opening portion. (The hatched portions inFIG. 13 c are fused portions.) Thezipper 5 is a well-known type (seeFIG. 14 ) which comprises agroove 7 integrally formed on abase 6 and aprotrusion 8 integrally formed on anotherbase 6. - The
zipper 5 is fused with the plastic films at both ends 5 a with thegroove 7 and theprotrusion 8 engaged with each other. Therefore, even when thezipper 5 is opened, the both ends 5 a are closed, and in closing thezipper 5 again, the user pinches the ends 5 a with his/her fingers from outside and slides his/her fingers from the ends 5 a along thezipper 5 while pressing theprotrusion 8 and thegroove 7 against each other. - When the
zipper 5 of the plastic bag is opened, the area of the open portion 3 (hatched inFIG. 13 b) is small. The end portions where thezipper 5 is fused with the plastic films are large (see “2 a” inFIG. 13 c) because the amount of the melted resin there is large and because thegroove 7 and theprotrusion 8 are fixed on the inner surfaces of the plastic films. Accordingly, the items which can be put into and taken out of the plastic bag through the open portion 3 are of sizes not more than a dimension D3, which is calculated by subtracting a width of the portions where thegroove 7 and theprotrusion 8 are covered by each other from a dimension D2 smaller than an inner dimension D1. - Also, if the
zipper 5 shrinks due to its own rigidity, the open portion 3 cannot be open sufficiently wide. Therefore, narrow plastic bags with widths not more than 40 mm have not been manufactured. - An object of the present invention is to provide a plastic zipper bag which can contain larger items than conventional plastic zipper bags by effectively using the inner dimensions of the plastic bag.
- Another object of the present invention is to provide a narrower plastic zipper bag than conventional plastic zipper bags, which items can be put into and taken out of.
- In order to attain the objects above, a plastic bag according to the present invention has a zipper on an inner surface of an upper opening portion of a bag body, the zipper having a groove and a protrusion engaging with and disengaging from each other, and both sides in the upper portion of the bag body are open.
- In the plastic bag according to the present invention, because the both sides in the upper portion of the bag body are open, the upper portion of the bag body can be open wide in spite of the existence of the zipper. Thereby, effective use of the inner dimensions of the bag body becomes possible, and bigger items can be put in the plastic bag, compared with conventional plastic bags. Also, the opening of the bag is not restricted by the rigidity of the zipper, and it is possible to manufacture zipper bags with widths less than 40 mm, which has been the limit, for example, zipper bags with a width of approximately 10 mm.
- Further, making use of the characteristic that the both sides of the upper portion of the bag body are open, it is possible to draw cords and cables contained in the bag through the open portions at the both sides. Thereby, electrical connections can be kept while the cords and cables are contained in the bag, and redundant portions of the cords and cables can be put in order compactly.
- In the plastic bag according to the present invention, the groove and the protrusion are not fused even at ends, and therefore, there are no start points of engaging the groove and the protrusion with each other, which exist in conventional zipper bags. In order for the engagement, the user puts a part of the protrusion in the groove and presses the rear sides of the zipper by finger. When it is a narrow bag, the user must press only one time. When it is a wide bag, the user must press the zipper several times to close the bag.
- The plastic bag according to the present invention may have a plural number of chambers. For example, by putting at least one heat fusable plastic sheet between a front film and a back film composing the bag body, a plural number of chambers can be formed. Also, by fusing the front film and the back film along at least one vertical line, a plural number of chambers can be formed.

FIG. 14 is an illustration of a zipper composed of a groove and a protrusion. - Embodiments of a plastic zipper bag according to the present invention are hereinafter described with reference to the accompanying drawings.
-
FIGS. 1 a-4 b show aplastic zipper bag 10A according to a first embodiment of the present invention. - As shown in
FIGS. 1 a and 1 b, theplastic bag 10A is composed of twoplastic films sides 13 and in anupper portion 14. - As the
films upper ends 14 of thefilms zipper 5 composed of agroove 7 made in abase 6 and a protrusion formed on another base 6 (seeFIG. 14 ) is fused. Thezipper 5 may be formed integrally with thefilms - A conventional plastic zipper bag has right and
left sides 13 fused from the bottom to theupper portion 14 where azipper 5 is provided. With respect to thezipper bag 10A according to the present invention, however,upper parts 13 a of the right andleft sides 13 are not fused. - Further, the
zipper bag 10A has aperforated line 16 and aslit 17 in theupper portion 14. Theperforated line 16 is used to cut off the upper fused end when opening thebag 10A, and theslit 17 is to start the cutting-off. - An item P is put into the
bag 10A shown byFIGS. 1 a and 1 b through anopen bottom 15, and then, thebottom 15 is fused as shown by the hatched portion inFIG. 2 a. Thereby, theplastic bag 10A has anupper portion 14 with open right andleft sides 13 a. - A user receives the
bag 10A containing an item P in the state shown byFIGS. 2 a and 2 b. In order to take the item P out of thebag 10A, first, as shown byFIGS. 3 a and 3 b, the user cuts off the upper fused end along theperforated line 16 to open thebag 10A. - Next, as shown by
FIGS. 4 a and 4 b, thegroove 7 and theprotrusion 8 of thezipper 5 are disengaged from each other, and theupper portion 14 is folded back. Thereby, theupper portion 14 of thebag 10A becomes wide open. In this state, the item P sticks out of theupper portion 14 and can be taken out of thebag 10A easily. Further, it is easy to put the item P into thebag 10A again. - Thus, according to the first embodiment, since the
upper portion 14 of thebag 10A has unfused open right and left sides, theupper portion 14 can be wide open in spite of the existence of the zipper 5 (seeFIGS. 4 a and 4 b), putting in and out of an item P, which is of a width nearly equal to the inner width D1 of thebag 10A, is possible. - With respect to a conventional bag, when the width D is small, it is difficult to open the
upper portion 14 because of the rigidity of thezipper 5. With respect to thebag 10A, however, even when the width D is small, for example, approximately 10 mm, it is easy to open theupper portion 14. - The upper fused end and the
perforated line 16 of thebag 10A are not indispensable and can be omitted. Also, if a small hole is made in theupper portion 14, thebag 10A can be used to hang and display a commodity. -
FIGS. 5 a-6 show aplastic zipper bag 10B according to a second embodiment of the present invention. - The
bag 10B is, asFIGS. 5 a, 5 b and 5 c show, basically of the same structure as thebag 10A according to the first embodiment. Therefore, the same members and the same parts are provided with the same reference symbols as those inFIGS. 1 a-4 b, and descriptions of these members and parts are omitted. - A characteristic of the
bag 10B is that at least one heatfusable plastic sheet 18 is nipped between the front andback films bag 10B has at least twochambers 19 a and 19 b. Thesheet 18 may be a plastic film, a non woven fabric, a foam plastic sheet or the like. -
FIG. 6 shows a state where theupper portion 14 of thebag 10B is folded back and becomes open. In this state, the upper end of thesheet 18 is located above the folded-down zipper 5 (groove 7 and protrusion 8), and items can be put into and put out of thechambers 19 a and 19 b through wide-open portions bag 10B can be used, for example, as a container for two CDs. When a non woven fabric or a foam plastic sheet is used as thesheet 18, thesheet 18 functions as a cushion. Also, printing may be performed on thetransparent films bag body 10B. -
FIGS. 7 a-8 b show a manufacturing method ofplastic zipper bags 10C according to a third embodiment of the present invention. - First, as
FIG. 7 a shows, while aplastic film 30 is extruded from a die into a tube, agroove 7 and aprotrusion 8 composing a zipper are extruded such that thegroove 7 and theprotrusion 8 are stuck integrally on the inner surface of thefilm 30. By adjusting the amount of resin extruded from the die and the volume of air blown into the tube, the size of the bag and the thickness of thefilm 30 are determined. Next, thefilm 30 is folded such that thegroove 7 and theprotrusion 8 face each other (seeFIG. 7 b). - Thereafter, as
FIG. 8 b shows, while the foldedfilm 30 is transported in a direction (shown by arrow F) step by step by a distance G, thefilm 30 is melted and cut at a position shown by the alternate long and dash line H. Before this melting/cutting step, cut-offs 31 are made in theupper portion 14. This is to permit each producedbag 10C to have anupper portion 14 with open right and left sides. Further, a perforated line may be made in theupper portion 14. - The
plastic zipper bag 10C produced by the above-described method is basically of the same structure as thebag 10A according to the first embodiment and has the same advantages as those of thebag 10A. - A
plastic zipper bag 10D according to a fourth embodiment is used to contain cords and cables of electric appliances such as a TV, a personal computer, an audio set, etc. - As
FIG. 9 shows, thebag 10D is basically of the same structure as thebag 10A according to the first embodiment. Therefore, the same member and the same parts are provided with the same reference symbols as shown inFIGS. 1 a-4 b, and descriptions of these members and parts are omitted. - A characteristic of the
bag 10D is that theupper portion 14 has relatively large cut-offs 35 at right and left sides, resulting in open right and left sides in theupper portion 14. Therefore, asFIG. 11 shows, it is possible to open theupper portion 14 of thebag 10D considerably wide. - In the rear side of a TV, a personal computer, an audio set or the like, usually, redundant portions of cords and cables are left disordered and entangled. As
FIG. 10 shows, by putting the middle portions of the cords and cables in thebag 10D and by drawing the cords and cables through the cut-offs 35, the redundant portions of the cords and cables can be put in order compactly while the electrical connections are kept. - The
bag 10D has asmall hole 36 in the bottom fusedportion 15. Thishole 36 is to permit thebag 10D to be hung from a hook on a column or a wall. - Further, if the
bottom portion 15 is made into a gusset, thebag 10D will have a wide bottom. -
FIG. 12 shows aplastic zipper bag 10E according to a fifth embodiment of the present invention. - This
bag 10E is basically of the same structure as thebag 10A according to the first embodiment. The same members and the same parts as those shown inFIGS. 1 a-4 b are provided with the same reference symbols, and description of these members and parts are omitted. - A characteristic of the
bag 10E is that the front andback films bag 10E is divided into threechambers 42 a, 42 b and 42 c. - The
bag 10E have the same advantages as thebag 10A, and moreover, thechambers 42 a, 42 b and 42 c can be used separately. - Plastic zipper bags according to the present invention are not limited to the embodiments above, and various changes and modifications are possible within the scope of the invention.
- The shapes of the sections of the protrusion and the groove of the zipper are arbitrarily designed. The method for manufacturing the bag bodies can be arbitrarily adopted, and also, the size of the bags can be arbitrarily designed for the purpose.
- Further, it is possible to combine the second embodiment and the fifth embodiment to produce a plastic bag with a large number of chambers.
