This invention has been made by the members of MIMURA Seminar, College of Law, Nihon, Univ. as a team. The present invention relates to a bag, in particular, to a double structure bag having an inner bag and an outer bag, which make it harder to leak the smell of contents therein.
When a product such as hamburgers or fries is purchased to go at a leading fast food restaurant, it was stored in a paper bag 300, which is illustrated in
However, by using the bag with a zipper, there is another problem that it will not be easy to put the food in and out because of its zipper function. For these reasons, in order to put the food in to and out from the bag easily, the bag 300 is closed b folding itself at where the opening is located.
However, the closure of the opening be released by a small impact, and the opening of the bag 300 is re-opened easily and unexpectedly. Therefore, it is deficient as to the function for closing the opening of the bag. The present invention is to enable to solve the above problems.
An objective of the present invention is to resolve the above described problem and to provide a double-structure bag having an outer bag and an inner bag. The objective is achieved by a double-structure bag including an inner bag including a second food storage opening, wherein the inner bag includes a first and second bent portions located in an area adjacent to the second food storage opening, and wherein the first bent portion includes first openings at both side, and the second bent portion includes second openings at both side; an outer bag in which the inner bag is stored, having a first food storage opening, wherein the outer bag includes a tunnel, which having third openings at its both ends; and two elongated zipping members, each of which is placed in one of the first and second bent portions, respectively, wherein both ends of each elongated zipping member are placed outside the outer bag by passing through the tunnel and by coming out from the third openings, respectively, whereby the second food storage opening is closed by pulling the elongated zipping members from the side to side, and wherein the elongated zipping members are tied together after area where the first food storage opening is formed is folded.
The invention will be more particularly described with reference to the accompanying drawings, in which:
The first preferred embodiment of the invention as to a writing equipment with scale attached is explained together with drawings as follows. In each drawing, the same reference numbers designate the same or similar components through all embodiments.
The double structure bag is used as follows. First, in a first embodiment, the one of the elongated zipping members 30a is placed in the first bent portion 2a by passing from the first opening 22a and to another first openings 22b, and then, the elongated zipping member 30a is placed in the second bent portion 2b by passing from the second opening 22d and to another second opening 22c. Another elongated zipping member 30b is placed in the second bent portion 2b passing in the opposite pathway, namely, by passing from the second opening 22d and to another second opening 22c, and then, the elongated zipping member 30b is placed in the first bent portion 2a by passing from the first opening 22a and to another first opening 22b.
Next, the both ends of the elongated zipping member 30a are placed outside of double structure bag 100 by passing through the tunnel 1 and by coming out from the third openings 12a, 12b, respectively. As well as the elongated zipping member 30a, the both ends of the elongated zipping member 30b are placed outside the double structure bag 100 by passing through the tunnel 1 and by coming out from the third openings 12a, 12b, respectively. Then, the area, where tunnel 1 is formed, is folded inwardly one or several times so that the first food storage opening 11 is closed lightly. Finally, the elongated zipping members 30a and 30b encompasses the outside of the folded first food storage opening 11, and the elongated zipping members 30a and 30b are tied together on the surface which is opposite to folded one.
Then, after the content, such as foods, is placed in the inner bag 20, the second food storage openings 21 is closed by pulling both ends of the elongated zipping members 30a and 30b. According to the structure described above, since the zipping members 30a and 30b are tied on the location as described above, the zipping members 30a and 30b can maintain the state against the force, which returns the folded area to the pre-folded location, and it can also maintain the folded state even the impact is applied to the double structure bag 100 from the outside. In addition, the prevention of the leakage of the smell the inner bag 20 can be expected.
As well as the first embodiment, a double structure bag 200 of the second embodiment includes an outer bag 10, an inner bag 20 and two elongated zipping members 30a and 30b. As shown in
In the second embodiment, as well as the first embodiment, the zipping member 30a is placed in the second tunnel 2a by passing from the first opening 22a and to another first opening 22b, and then, the zipping members 30a is placed in the third tunnel 2b by passing from the second opening 22d and to another second opening 22c. Another zipping member 30b is placed in the third tunnel 2b by passing in the opposite pathway, namely, by passing from the second opening 22d and to another second opening 22c, and then, the zipping member 30b is placed in the second tunnel 2a by passing from the first opening 22a and to another first opening 22b. Then, after the content, such as food, is placed in the inner bag 20, the second food storage opening 21 is closed by pulling both ends of the zipping members 30a and 30b.
Then, the inner bag 20 is placed in the outer bag 10. Next, each of the elongated zipping members 30a, 30b passes through one of the fourth openings 40a, 40b, respectively, and area where the opening 11 is formed is bent and closed. Thereafter, by tying the elongated zipping members 30a, 30b, it is expected that the contents can hardly jump out from the inner bag 20.
In a first and a second embodiments, while the material of the outer bag 10 is paper, the material of the inner bag 20 is primarily aluminum or polyethylene. However, it is not necessary to limited to the above mentioned material. Further, paper, cotton, metal, vinyl and synthetic resin can be used for them. Moreover, the elongated zipping members 30a, 30b may be made of metal primarily, but other material such as paper, cotton, wire, polyethylene and synthetic resin can be used for them.
According to a first embodiment, since the plurality of openings, such as the first openings 22a, 22b and the second openings 22c, 22d, are formed in the inner bag 20, the durability may be is less than the other parts. Therefore, the area in which the first openings 22a, 22b and the second openings 22c, 22d are formed may be formed slightly thick. Similarly, according to a second embodiment, the first area in which the fourth openings 40a and 40b are formed slightly thicker than other area for the same reason.
While the invention has been described with reference to illustrative embodiments, this description is not intended to be construed in a limiting sense. Thus, shapes, size and physical relationship of each component are roughly illustrated so the scope of the invention should not be construed to be limited to them. Further, to clarify the components of the invention, hatching is partially omitted in the cross-sectional views. Moreover, the numerical description in the embodiment described above is one of the preferred examples in the preferred embodiment so that the scope of the invention should not be construed to limit to them.
Various other modifications of the illustrated embodiment will be apparent to those skilled in the art on reference to this description. Therefore, the appended claims are intended to cover any such modifications or embodiments as fall within the true scone of the invention.
