This application is based upon and claims the benefit of priority from Japanese patent application No. 2017-209313, filed on Oct. 30, 2017, the disclosure of which is incorporated herein in its entirety by reference.
The present invention relates to a packaging bag and a method of using a packing structure.
Japanese Unexamined Patent Application Publication No. H6-286759 discloses a reclosable zipper bag with male and female engaging zipper profiles made of synthetic resin placed on an inner surface of a bag opening.
When packaging a product in the field of car navigation devices, an instruction manual and an SD memory card (registered trademark) in which map data is stored are packed into different packaging bags in general. This is because there is a possibility that a new version of map data is released after a product is shipped and before it is sold to an end consumer, and in such a case it is necessary to replace the SD memory card in the product with another SD memory card in which the new version of map data is stored, or rewrite the map data in the SD memory card in the product.
Further, because a packaging bag for packing an SD memory card (which is referred to hereinafter as SD packaging bag) is smaller than a packaging bag for packing an instruction manual (instruction manual packaging bag), it has been considered preferable to attach the SD packaging bag on a certain part of the instruction manual packaging bag by a tape in order to prevent the SD packaging bag from getting lost in a packaging box.
However, the attaching the SD packaging bag onto the instruction manual packaging bag by a tape has the following problem. When a new version of map data is released, it is necessary to peel the tape off the instruction manual packaging bag and take the SD memory card out of the SD packaging bag in order to replace the SD memory card or rewrite the map data in the SD memory card, and this can damage the instruction manual packaging bag, which causes the need for replacement of the instruction manual packaging bag or the degradation of the appearance of the instruction manual packaging bag.
According to a first aspect of the embodiment, there is provided a packaging bag including a packaging bag body having a bag opening, and an exposed zipper profile part having a male or female engaging surface, the engaging surface being exposed outside when the bag opening is closed.
According to a second aspect of the embodiment, there is provided a method of using a packing structure including a step of preparing two packaging bags, each including a packaging bag body having a bag opening and an exposed zipper profile part having a male or female engaging surface, the engaging surface being exposed outside when the bag opening is closed, and a step of joining the two packaging bags by engaging the exposed zipper profile parts with each other.
The above and other aspects, advantages and features will be more apparent from the following description of certain embodiments taken in conjunction with the accompanying drawings, in which:
A first embodiment is described hereinafter with reference to
Further, the below-described embodiments show a structure and a method for implementing the technical idea of the present invention by way of illustration only, and the technical idea of the present invention does not limit the material, shape, structure, arrangement or the like of the elements to those described below. Various modifications may be made to the technical idea of the present invention within the spirit and scope of the appended claims.
An instruction manual 4 of a car navigation device, for example, is packed into the large packaging bag 2. The instruction manual 4 is one specific example of a large object to be packed. An SD memory card 5 in which map data to be used for a car navigation device, for example, is packed into the car navigation device. The SD memory card 5 is one specific example of a small object to be packed. Each of the instruction manual 4 and the SD memory card 5 is in the shape of a thin rectangular sheet. The instruction manual 4 is larger than the SD memory card 5 in height, width and thickness.

As shown in
The front sheet part 7 and the rear sheet part 8 are connected through a folded part 10 at the lower end of the large packaging bag 2. The front sheet part 7 and the rear sheet part 8 may be connected by welding at the lower end of the large packaging bag 2. The front sheet part 7 has an upper end 7a. The rear sheet part 8 has an upper end 8a. The rear sheet part 8 extends more upward than the upper end 7a of the front sheet part 7. In other words, the upper end 8a of the rear sheet part 8 is located upper than the upper end 7a of the front sheet part 7. To be specific, the rear sheet part 8 has an upper extension 8b, which is a part that extends more upward than the upper end 7a of the front sheet part 7. Referring back to
As shown in
Specifically, the front sheet part 7 has an inner surface 7c that faces the rear sheet part 8. Likewise, the rear sheet part 8 has an inner surface 8c that faces the front sheet part 7.
The male zipper profile part 20 is formed near the bag opening 6 on the inner surface 7c of the front sheet part 7. The male zipper profile part 20 is formed to project from the inner surface 7c of the front sheet part 7 toward the rear sheet part 8. The male zipper profile part 20 is formed along the width direction.
The male zipper profile part 20 has a male engaging surface 20a. The male zipper profile part 20 has a thin part 20b and a thick part 20c which is larger than the thin part 20b in height. In other words, the cross-sectional shape of the male zipper profile part 20 gets thicker as it goes from the front sheet part 7 toward the rear sheet part 8.
As shown in
As shown in
The female zipper profile part 21 has a female engaging surface 21a. In other words, the female zipper profile part 21 is formed in a substantially 2 shape that branches into two parts as it goes from the rear sheet part 8 toward the front sheet part 7.
As shown in
As shown in
The small packaging bag 3 is described hereinafter with reference to
A method of using the packing structure 1 is described hereinafter with reference to
As shown in
In an actual use, when map data is updated, an operator first pulls the exposed zipper profile part 25 of the small packaging bag 3 out of the exposed zipper profile part 25 of the large packaging bag 2 and thereby detaches the small packaging bag 3 from the large packaging bag 2.
Next, the operator takes the SD memory card 5 out of the small packaging bag 3, and rewrites the map data stored in the SD memory card 5 or replaces it with the SD memory card 5 in which new map data is stored. Then, the operator packs the written or new SD memory card 5 into the small packaging bag 3, and closes the bag opening 6 of the small packaging bag 3.
After that, the operator engages the exposed zipper profile part 25 of the large packaging bag 2 and the exposed zipper profile part 25 of the small packaging bag 3 with each other, thereby joining the large packaging bag 2 and the small packaging bag 3 again.
In this manner, by using the exposed zipper profile part 25 of the large packaging bag 2 and the exposed zipper profile part 25 of the small packaging bag 3, it is possible to easily attach and detach the large packaging bag 2 and the small packaging bag 3. When the small packaging bag 3 is attached onto the large packaging bag 2 by using an adhesive tape or the like, for example, it is necessary to peel the adhesive tape off the large packaging bag 2, which can damage the large packaging bag 2. Therefore, the above-described way of attaching and detaching the large packaging bag 2 and the small packaging bag 3 with use of the exposed zipper profile part 25 of the large packaging bag 2 and the exposed zipper profile part 25 of the small packaging bag 3 also has the effect of avoiding the damage of the large packaging bag 2.
The first embodiment is described above. The above-described first embodiment has the following features.
Specifically, as shown in
Further, as shown in
Further, as shown in
Further, as shown in
The above-described first embodiment can be modified as follows.
Specifically, because the male zipper profile part 20 and the female zipper profile part 21 are complementary to each other in the above-described first embodiment, the following embodiments and modified examples, the male zipper profile part 20 (and the engaging surface 20a) may be replaced with the female zipper profile part 21 (and the engaging surface 21a), and the female zipper profile part 21 (and the engaging surface 21a) may be replaced with the male zipper profile part 20 (and the engaging surface 20a).
Further, in the above-described first embodiment, the packaging bag body 9 has the opening 22 for the exposed zipper profile part 25 to be exposed outside as shown in
A second embodiment is described hereinafter with reference to
In the above-described first embodiment, the front sheet part 7 of the packaging bag body 9 has the opening 22, so that a part of the female zipper profile part 21 serves as the exposed zipper profile part 25, as shown in
On the other hand, in this embodiment, the front sheet part 7 of the packaging bag body 9 does not have the opening 22, and the male zipper profile part 20 extends continuously from the left side welded part 11 to the right side welded part 12 as shown in
Further, in this embodiment, a female zipper profile part 31 having a female engaging surface 31a is formed on the inner surface 8c of the upper extension 8b of the rear sheet part 8. The female zipper profile part 31 is one specific example of the exposed zipper profile part. The female zipper profile part 31 that is formed on the inner surface 8c of the upper extension 8b of the rear sheet part 8 is not covered with the front sheet part 7 in the thickness direction, and therefore it is exposed outside when the bag opening 6 is closed. In this structure, because the male zipper profile part 20 and the female zipper profile part 21 engage with each other continuously from the left side welded part 11 to the right side welded part 12, it is possible to close the bag opening 6 more tightly than in the above-described first embodiment. Further, because the female zipper profile part 21 and the female zipper profile part 31 are formed on the same inner surface 8c, it is possible to form the female zipper profile part 31 at low costs, and it is thereby possible to reduce the costs of the large packaging bag 2.
The second embodiment is described above. The above-described second embodiment has the following features.
The packaging bag body 9 includes the front sheet part 7 as a first resin sheet part on which the male zipper profile part 20 having the male engaging surface 20a is formed and the rear sheet part 8 as a second resin sheet part on which the female zipper profile part 21 having the female engaging surface 21a is formed. The bag opening 6 closes by engaging the male zipper profile part 20 and the female zipper profile part 21 with each other. The rear sheet part 8 extends more upward than the upper end 7a of the front sheet part 7, and the female zipper profile part 31 that serves as the exposed zipper profile part is formed on this extended part, which is the upper extension 8b. In this structure, one specific example of the placement of the female zipper profile part 31 that serves as the exposed zipper profile part is provided.
Further, the female zipper profile part 31 that serves as the exposed zipper profile part is formed on the same surface as the inner surface 8c on which the female zipper profile part 21 is formed. In this structure, it is possible to form the female zipper profile part 31 at low costs, and it is thereby possible to reduce the costs of the large packaging bag 2.
Note that, in the above-described second embodiment, the rear sheet part 8 extends more upward than the upper end 7a of the front sheet part 7, and the female zipper profile part 31 is placed on this extended part, which is the upper extension 8b. Alternatively, the front sheet part 7 may extend more upward than the upper end 8a of the rear sheet part 8, and the female zipper profile part 31 may be placed on this extended part. Further, as described earlier, the male zipper profile part, instead of the female zipper profile part 31, may be formed as the exposed zipper profile part.
A third embodiment is described hereinafter with reference to
In the above-described first embodiment, the male zipper profile part 20 is formed on the inner surface 7c of the front sheet part 7, the female zipper profile part 21 is formed on the inner surface 8c of the rear sheet part 8, and the male zipper profile part 20 and the female zipper profile part 21 engage with each other to thereby close the bag opening 6 as shown in
On the other hand, in this embodiment, the male zipper profile part 20 and the female zipper profile part 21 are omitted, and the bag opening 6 closes by folding back the upper part of the packaging bag body 9 and fastening it with an adhesive tape 32 as shown in
Note that, the female zipper profile part 33 that serves as the exposed zipper profile part may be formed on an outer surface 8d of the rear sheet part 8 of the packaging bag body 9, rather than on the outer surface 7d of the front sheet part 7 of the packaging bag body 9.
According to each of the embodiments described above, it is possible to avoid the damage of a packaging bag even when another item is attached to and detached from the packaging bag.
The first to third embodiments can be combined as desirable by one of ordinary skill in the art.
A reference embodiment is described hereinafter with reference to
As shown in
The first packaging bag 51 has a bag opening 53 that opens upward. To be specific, the first packaging bag 51 has a front sheet part 54 and a rear sheet part 55. The front sheet part 54 and the rear sheet part 55 constitute a packaging bag body 56 of the first packaging bag 51. The front sheet part 54 and the rear sheet part 55 are connected by welding at the lower end of the packaging bag body 56. As shown in
Likewise, the second packaging bag 52 has a bag opening 60 that opens upward. To be specific, the second packaging bag 52 has a front sheet part 61 and a rear sheet part 62. The front sheet part 61 and a rear sheet part 62 constitute a packaging bag body 63 of the second packaging bag 52. The front sheet part 61 and a rear sheet part 62 are connected by welding at the lower end of the packaging bag body 63. The front sheet part 61 has an upper end 61a. The rear sheet part 62 has an upper end 62a. The rear sheet part 62 extends more upward than the upper end 61a of the front sheet part 61 and has an upper extension 62b, which is the extended part. A female zipper profile part 64 having a female engaging surface 64a is formed on an inner surface 62c of the upper extension 62b.
The first packaging bag 51 and the second packaging bag 52 are connected by welding at the lower end of the packing structure 50. The first packaging bag 51 and the second packaging bag 52 may be formed separately and then joined by welding, or the first packaging bag 51 and the second packaging bag 52 may be formed simultaneously by blocking in the internal space of one cylindrical packaging bag by welding at the center in the longitudinal direction.
A method of using the packing structure 50 is as follows. As shown in
When map data is updated, an operator first pulls the female zipper profile part 64 of the second packaging bag 52 out of the male zipper profile part 57 of the first packaging bag 51 and thereby opens the bag opening 53 and the bag opening 60 at the same time.
Next, the operator takes the SD memory card 70 out of the first packaging bag 51, and rewrites the map data stored in the SD memory card 70 or replaces it with the SD memory card 70 in which new map data is stored. Then, the operator packs the written or new SD memory card 70 into the first packaging bag 51, engages the male zipper profile part 57 of the first packaging bag 51 and the female zipper profile part 64 of the second packaging bag 52 with each other again, thereby closing the bag opening 53 of the first packaging bag 51 and the bag opening 60 of the second packaging bag 52 at the same time.
In this structure, because the first packaging bag 51 and the second packaging bag 52 are joined at all times at the lower end of the packing structure 50, the first packaging bag 51 is not lost in any case. Further, this is convenient because the bag opening 53 of the first packaging bag 51 and the bag opening 60 of the second packaging bag 52 can be closed at the same time simply by engaging the male zipper profile part 57 and the female zipper profile part 64 with each other.
While the invention has been described in terms of several embodiments, those skilled in the art will recognize that the invention can be practiced with various modifications within the spirit and scope of the appended claims and the invention is not limited to the examples described above.
Further, the scope of the claims is not limited by the embodiments described above.
Furthermore, it is noted that, Applicant's intent is to encompass equivalents of all claim elements, even if amended later during prosecution.
