Description

To provide a storage bag with a zipper that allows the contents to be removed without touching the zipper and can be sealed after use.

Traditionally, the zipper of a storage bag with a zipper (hereafter referred to as a zipper bag) has been attached in a straight line with the recessed and protruding parts on the side of the product that contains the contents.

Patent Document 1 also discloses that by providing a movable, foldable, angled tag on the inside of the opening, the contents can be transferred out without soiling the uneven surface of the zipper. Patent Document 2 discloses that the uneven surface of the zipper is configured on the front and back of the bag. Patent Document 3 discloses that the contents can be transferred out by passing through the area near the inside of the folded part. Patent Document 4 discloses that the bag can be sealed using adhesive-applied parts and adhesive parts on the front and back of the bag.

Furthermore, in Patent Document 1, the bottom of the mountain-shaped tag is fixed, and the peak is left unglued so that it can be folded in and out through the opening. In Patent Document 2, both of the concave and convex parts of the zipper are composed of a single straight line. In Patent Document 3, the folded part can be stored. In Patent Document 4, the release material part and the adhesive part come together to seal the item.

In the case of the angle tag described in Patent Document 1, if the angle tag does not return to the contents after the contents are removed, it must be touched with a finger, and there is a concern that the contents may touch the surface that comes into contact with the finger, which may become unsanitary. Furthermore, when returning the angle tag without using a finger, a tool such as clean chopsticks must be used each time, which is inconvenient. In Patent Document 2, both zippers are shaped with only a single straight line, and with this structure, gaps are generated when the bag is sealed, and it is not possible to seal the bag to prevent dust and moisture from entering the bag. In Patent Document 3, the folded part is retractable, but gaps are generated when the bag is sealed, and it is not possible to seal the bag to prevent dust and moisture from entering the bag. In Patent Document 4, when the bag is opened, adhesive or release agent is applied to the edge, so the finger touches it, which is not sanitary. Even if the part coated with adhesive or release agent is replaced with the concave part of the zipper and the convex part of the zipper, the finger touches the concave part of the zipper or the convex part of the zipper when the bag is opened, which is not sanitary. In addition, the adhesive used weakens the seal, making it difficult to repeatedly open and close it, and when the seal is open, dust sticks to the adhesive, making it difficult to remove.

In addition, with conventional zipper bags, the contents come into contact with the zipper when they are removed, and the contents stick to the uneven parts of the zipper, leaving them dirty and unsanitary. For example, when removing granular toppings or liquid sauce, the contents cannot be completely removed by flicking the bag with a finger from the outside, and closing the zipper in this state does not provide a seal to prevent dust and moisture from entering the bag.

In addition, when using a spoon to scoop out powdered flour, the user must carefully scoop the flour without touching the zipper, making the process cumbersome.

In order to solve the above problems, the zippered storage bag described in claim 1 is characterized in that the zipper is provided on the inside of one side of the bag and on the outside of the other side, the positions of the zipper recess and zipper protrusion are symmetrical in the up-down direction with respect to the fold line formed by folding the two sides together when the zippered bag is fully opened, both ends of the zipper recess and both ends of the zipper protrusion always meet, a space surrounding the zipper on the inside of the bag is provided between the edge of the side on which the zipper is provided on the inside of the bag and the inner zipper, there is an opening for removing the contents, the opening is located via the fold line on the side with the zipper on the outside, and the opening is surrounded by the zipper recess and zipper protrusion and the fold line formed by folding the two sides together when the zipper recess and zipper protrusion are brought together, and is completely stored inside the bag, and the zipper is joined so that the contents can be sealed without coming into contact with the outside air. In such a zipper bag, the opening protrudes through the fold line of the side with the zipper on the outside, so the contents are restricted from being ejected and do not fly out here and there, making it easy to use. Also, since one zipper is attached to the outside of the bag, if the contents are liquid, the bag can be tilted and removed directly from the opening, if the contents are granular, the bag can be vibrated to remove it from the opening, and if the contents are powdery, the bag can be moved along the opening to remove it from the opening, without the contents touching either the recessed or protruding parts of the zipper. Also, when the joined zippers are separated, there is a space on the inside of the bag on the side where the zipper is attached, so it is okay to hold the space anywhere, and the bag can be opened without touching either the recessed or protruding parts of the zipper with your fingers. This space surrounds the zipper on the inside of the bag, so when the recessed and protruding parts of the zipper are joined together, the bag is sealed without any gaps, which prevents dust and moisture from entering the bag and allows for hygienic storage.

In the storage bag with a zipper as described in claim 2, the zipper is provided on the inside of one side of the bag and on the outside of the other side, the positions of the recessed and protruding parts of the zipper are symmetrical in the vertical direction with respect to the fold line created by folding the side on the inside of the bag on which the zipper is provided when the zipper bag is fully opened, both ends of the zipper recess and both ends of the zipper protrusion are always aligned, a space surrounding the zipper on the inside of the bag is provided between the edge of the side on which the zipper is provided on the inside of the bag and the inner zipper, there is an opening for removing the contents, the opening is located on the side on which the zipper is provided on the outside, and when the recessed and protruding parts of the zipper are aligned with each other, the opening is surrounded by the zipper recess, the zipper protrusion and the fold line and is completely stored inside the bag, and the zipper is joined so that the contents can be sealed without coming into contact with the outside air. In such a zipper bag, one of the zippers is attached to the outside of the bag, so if the contents are liquid, the bag can be tilted and removed directly from the opening, if the contents are granular, the bag can be vibrated to remove the contents from the opening, and if the contents are powdery, the bag can be run along the side of the bag to remove the contents from the opening without touching the zipper. Also, when separating the joined zippers, by leaving a space on the side where the zipper is attached on the inside of the bag, the bag can be opened without touching either the concave or convex part of the zipper, so the concave and convex parts of the zipper can be kept hygienic. This space surrounds the zipper on the inside of the bag, so there is an effect that it does not matter where the space is. And after using the bag, the zipper can be joined without touching the opening, so there is an effect that the intrusion of dust into the bag is prevented and the bag can be stored hygienically.

In the storage bag with a zipper according to claim 3, the zipper is provided on the inside of one side of the bag and on the outside of the other side, and the positions of the zipper recess and zipper protrusion are such that when the zipper bag is fully opened, the zipper recess and zipper protrusion are vertically symmetrical with respect to the fold line formed by overlapping and folding the two sides, both ends of the zipper recess and both ends of the zipper protrusion always match, a space is provided between the edge of the side on which the zipper is provided on the inside of the bag and the inner zipper, there is an opening that is an opening for removing the contents, the opening is provided via the fold line on the side with the zipper on the outside, and the opening is when the zipper recess and the zipper protrusion are matched with each other The structure is characterized by the fact that the zipper recess and zipper protrusion are surrounded by a fold line formed by overlapping and folding the two surfaces, and the entire structure is stored inside the bag, and the zipper is joined so that the contents can be sealed without coming into contact with the outside air.Furthermore, the structure can include at least one structure selected from the group consisting of a structure in which a sealing seal is provided before the zippered storage bag is opened, a structure in which the two sides that intersect with the zipper are recessed into a gourd shape, a structure in which the bottom of the bag has depth so that the bag can remain in the opened state and stand on its own, a structure in which a guide for transferring the contents is attached to the opening through which the contents can be removed, and a structure in which the opening through which the contents can be removed is narrowed by sealing both ends toward the center in a limited manner. In addition to the effects of the zipper bag described in claim 1, this type of zipper bag has at least one of the following effects: the contents will not come out even if the product is accidentally turned upside down when moving or displaying the product; the gourd-shaped depression makes it easy to hold the zipper bag in your hand when holding the sides; the contents will collect at the bottom when placed on a table, making it easy to stand upright in a cylindrical shape; the contents can be removed by following a guide; and the width at which the contents can be removed is limited, making it even easier to remove.

In the storage bag with a zipper according to claim 4, the zipper is provided on the inside of one side of the bag and on the outside of the other side, and the positions of the recessed and protruding parts of the zipper are symmetrical in the vertical direction with respect to the fold line formed by folding the side on which the zipper is provided on the inside of the bag when the zipper bag is fully opened, both ends of the zipper recess and both ends of the zipper protrusion are always aligned, a space is provided between the edge of the side on which the zipper is provided on the inside of the bag and the inner zipper to surround the zipper on the inside of the bag, an opening is provided as an opening for removing the contents, the opening is located on the side on which the zipper is provided on the outside, and the opening is located between the recessed and protruding parts of the zipper The zipper concave portion and the zipper convex portion are surrounded by the fold lines when the two pieces are put together, and the zipper is joined to seal the contents without exposing them to the outside air. The zippered storage bag can further include at least one of the following structures: a sealing seal is provided before the bag is opened; two sides that intersect with the zipper are indented into a gourd shape; a structure with depth at the bottom of the bag that allows the bag to be held in the open position and stand on its own; a structure with a guide for removing the contents at the opening where the contents are taken out; and a structure in which the opening where the contents are taken out is narrowed by being tightly attached from both ends toward the center. In addition to the effects of the zipper bag described in claim 2, this zipper bag has at least one of the following effects: the contents do not come out even if the product is turned upside down when it is moved or displayed; the gourd-shaped indentation makes it easy to hold the zipper bag in your hand when holding the sides; the contents accumulate at the bottom when placed on a table and easily stand on their own in a cylindrical shape; the contents can be taken out along the guide; and the width of the contents that can be taken out is limited, making it even easier to take out.

In order to solve the above problems, the present invention has a zipper with an opening for removing the contents that is attached to the outside of the bag, so that both solid and liquid contents can be removed without touching the zipper part. Also, if the zippers that are joined with a space on the inside of the bag can be separated, the bag can be used without touching either the concave or convex part of the zipper.

Figure 1 is a perspective view of the state in which the zipper inside the bag a and the zipper outside the bag b are opened after removing the sealing seal s of the product. In the conventional zipper bag, both of the uneven parts of the zipper are on the inside of the bag, and the shape of the zipper is only one straight line, but in the zipper of the present invention, one side is on the outside of the bag, like the zipper on the outside of the bag b, and the shape of the zipper is other than only one straight line. In addition, the uneven parts of the zipper are connected by the part where both ends of the zipper inside the bag j and the zipper on the outside of the bag meet, and there is no part where the uneven parts of the zipper are separated. The positions of the zipper inside the bag a and the zipper outside the bag b are symmetrical in the vertical direction with respect to the folding line on the surface where the zipper is provided on the inside of the bag c, which is used to join the zippers together when opening. Since this figure is a perspective view, the folding line on the surface where the zipper is provided on the inside of the bag c and the folding line on the surface where the zipper is provided on the outside of the bag n overlap. In addition, the zipper on the outside of the bag b and the opening for taking out the contents d are configured on the surface where the zipper is provided on the outside of the bag m. Furthermore, the edge of the opening o does not overlap with the zipper on the inside of the bag a, and the space q is the area between the zipper on the inside of the bag a and the edge of the face with the zipper on the inside of the bag r, and the edge of the face with the zipper on the inside of the bag r does not contact any other edges.

Figure 2 shows a product with an S-sealing seal attached. Even if the zippers come apart when the product is transported, displayed, or moved, the S-sealing seal will prevent the contents from spilling out. This figure is just one example, and the S-sealing seal can be placed so that it surrounds the zippers when they are joined.

Figure 3 shows a gourd-shaped zipper bag. f The indentation makes it easier to hold the zipper bag in your hand by holding the gourd-shaped side.

Figure 4 shows a zipper bag with depth. When this type of zipper bag is placed on a table, the contents tend to accumulate at the bottom, making it easier for the bag to stand upright in a cylindrical shape.

In Figure 5, the opening for removing the contents (d) has a guide (h) to make it easier to remove runny products or liquids. An example of a guide is a linear groove, notch, or depression. However, other structures are also acceptable as long as they function as a guide.

Figure 6 shows a zipper bag with a narrower opening. This further limits the width at which the contents can be removed, making them easier to take out.

Figure 7 shows the q space being pinched between fingers to separate the connected zipper recess and zipper protrusion. This q space surrounds the zipper on the inside of the bag, so it doesn't matter where the q space is. This action is hygienic because neither the zipper recess nor the zipper protrusion is touched.

Figure 8 shows an oblique view of a zippered bag with the zipper open and the contents visible.

Figure 9 shows an example of how to use the bag when the contents e are liquid or granular. Hold the side of the bag where the two sides meet with your hand, vibrate the bag, and pass the contents d through the opening for removing the contents. The contents e will not come into contact with either the zipper on the inside of the bag a or the zipper on the outside of the bag b.

Figure 10 shows an example of how to use the bag when the contents e are in a powder form, such as wheat flour. When using the spoon to scoop the contents, if you take them out along the opening for taking out the contents d, the contents e will not come into contact with either the zipper on the inside of the bag a or the zipper on the outside of the bag b.

Figure 11 is a cross-sectional view of the process of aligning the zipper on the inside of the bag (a) with the zipper on the outside of the bag (b) after the contents have been removed. The surface with the zipper on the inside (l) is aligned with the opening for removing the contents (d), and then the fold line on the surface with the zipper on the inside (c) is aligned with the fold line on the surface with the zipper on the outside (n), and the bag is folded toward the zipper on the outside of the bag (b).

Figure 12 is a cross-sectional view of the zipper bag after the zipper unevenness p is connected. The opening d for removing the contents can be completely stored inside the bag when the zipper on the inside of the bag a and the zipper on the outside of the bag b are connected.

Figure 13 shows an example of a zipper that changes the shape of the zipper on the inside of the bag a and the zipper on the outside of the bag b in Figure 1, and shows a zipper that draws an arc k. j Any shape is acceptable as long as there is a part where both ends of the inner zipper and the outer zipper meet.

Figure 14 shows a variation of the shape of the opening for removing the contents in Figure 1 (d), with no fold line on the surface where the zipper is provided on the outside (n). This is just one example, and the edge of the opening (o) can be configured to overlap with the fold line on the surface where the zipper is provided on the inside (c), or be positioned closer to the zipper on the outside of the bag (b).

Figure 15 is a front view of the zipper bag and the zipper part after the zipper unevenness is joined, p. The opening for removing the contents, d, is surrounded by the zipper after the zipper unevenness is joined, p, and the fold line on the surface where the zipper is provided on the inside, c, and is completely stored inside the bag. The zipper unevenness is connected by the part where both ends of the inner zipper and the outer zipper meet, j, creating a seal to prevent dust from entering the bag. Since this is a transparent view, the fold line on the surface where the zipper is provided on the inside, c, and the fold line on the surface where the zipper is provided on the outside, n, overlap, and the opening for removing the contents, d, overlaps with the surface where the zipper is provided on the inside, l.

As described above, if the opening is surrounded by the zipper and the fold lines when the zipper is attached and can be completely contained within the bag, then a zipper bag can be constructed that can be sealed and prevents dust from entering the bag even if the shape of the zipper or the size and shape of the opening are changed, as shown in Figures 13 and 14. Furthermore, no matter what state the contents are in, if they are removed from the side where the zipper is attached to the outside of the bag, the contents will not get into the uneven parts of the zipper on the inside of the bag A and the zipper on the outside of the bag B.

In known zipper bags, one side of the zipper unevenness is composed of only a single straight line, but in this application, it is a shape other than just a single straight line. Although it is stated that one side is , the other side must have the same shape, otherwise the bag cannot be sealed to prevent dust from entering the bag, and this will be omitted. If zipper unevenness is provided on both the front and back of the bag, one side of the zipper must be a shape other than just a single straight line, and both ends of the zipper unevenness must always be joined together, otherwise the bag cannot be sealed to prevent dust from entering the bag. Furthermore, by providing an opening that is an outlet for the contents, it is easy to use and can be stored hygienically. It is these characteristics that are the invention of this application.

Depending on the type of contents and the purpose of use, the structure of the zipper bag in Figures 1, 13, and 14 can be changed by including at least one structure selected from the group consisting of the structures in Figures 2 to 6.

In conventional zipper bags, the zippers are attached to the inside of the bag, so when removing the contents, they come into contact with the zipper, making it difficult to achieve the ideal sealing effect. However, with the present invention, the contents can be removed without touching the zipper, so the ideal effect of a zipper bag can be achieved, which is to prevent dust from entering the bag and to seal it.
