Description

  The present invention relates to a bag that accommodates a disposable diaper and a disposable diaper package that accommodates the disposable diaper in the bag.

In general, disposable diapers such as paper diapers are folded and overlapped to form a diaper laminate, which is stacked in a plurality of stages and packaged entirely in a gusset bag such as a polyethylene film and is commercially available. In this bag, a handle for carrying is cut out at the top and an opening perforation for taking out the diaper is formed.
For example, a technique has been proposed in which a perforation is made to make a round in the longitudinal direction of the bag in order to facilitate the work of transferring the diaper to an arrangement chiffon (see Patent Document 1). Moreover, when a diaper laminated body is compressed and packaged, it becomes difficult to take out the diaper with a compressive force. Therefore, a technique has been proposed in which triangular perforations are formed in the gusset folding portion (see Patent Document 2).

By the way, in hospitals, nursing homes, etc., a paper diaper is placed on a cart and enters a patient's or resident's room to exchange the patient's or resident's paper diaper. At that time, there are many cases where it is difficult to clean up the disposable diaper after use. Therefore, there are cases where the opening of the paper diaper bag is greatly cut and widened with scissors or the like, the handle is hooked on a basket car, and used as a garbage bag. Since the paper diaper bag is made of a relatively thick and milky white film, the filth of the used paper diaper is difficult to see through and is suitable for use as a treatment bag. However, since the perforated paper diaper bag has a perforation that tears the packaging bag in the longitudinal direction, the opening cannot be widened and it is difficult to use it as a garbage bag. Also, as described above, cutting the paper diaper bag with scissors or the like and tearing it into a garbage bag becomes complicated.
That is, the present invention provides a disposable diaper bag that can be easily used as a trash bag by enlarging the opening and adjusting the position of the perforation line of the disposable diaper bag and hanging the handle on a hook or the like. The purpose is to provide disposable diaper packages.

In order to solve the above-mentioned problems, a disposable diaper bag according to the present invention is a gusset bag-like shape having a pair of opposed flat portions and gusset folds folded inward in a V shape from both ends of the flat portions. A disposable diaper bag, wherein the upper end side of the flat part is sealed, and a central part between the both ends is cut out to form a handle, and is located below the seal and in a lateral direction connecting the both ends. In addition, a perforation that penetrates the flat surface portion and the gusset folding portion is formed, and the perforation is not formed in the lower portion of the handle, or the ratio of the cut portion of the perforation is reduced. Yes.
Such a configuration works as follows. First, the perforation formed on the one plane portion side is broken, and the central portion is broken laterally with scissors and hands. When the handle is pulled up, each perforation located on one flat surface side of the gusset folding portion is broken, and the one flat surface portion and both gusset folding portions are separated from the seal portion, and the disposable diaper package ( The upper surface of the disposable diaper bag is opened with the maximum size (the same dimension as the cross-sectional shape). On the other hand, the other plane part remains integral with the seal part, and since there is no perforation (less) in the center part and the strength is maintained, the handle on the other plane part side is hooked to the hook or door knob of the car It can be used as a trash bag that is hooked on the door etc. and has a wide opening.

The lateral length of the handle is preferably 50 to 70 mm.
In the perforation excluding the lower part of the handle, the ratio represented by (the length of the cut part / the length of the bond part) is preferably 1/3 to 2/1.

  The disposable diaper package of this invention accommodates the diaper laminated body which piled up the surface of several folded disposable diapers in the said bag for disposable diapers.

  According to the present invention, there is provided a disposable diaper bag that can be easily used as a trash bag by enlarging the opening and adjusting the position of the perforation of the disposable diaper bag to hang a handle on a hook or the like. can get.

It is a perspective view of a disposable diaper package. It is an enlarged view of a perforation. It is process drawing which shows the aspect which opens a disposable diaper package. It is a figure which shows the guidance display part provided in the predetermined position of the center part.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 shows a plan view of a disposable diaper bag 10 according to an embodiment of the present invention. The disposable diaper bag 10 is made of a plastic film such as polyethylene, and has a pair of opposing flat portions 1 and 3 and both ends 1a and 1b (3a and 3b) of the flat portions 1 and 3 in a V shape inside. It is in the shape of a gusset bag having folded gusset folding portions 2 and 4. As shown in FIG. 2, the gusset bag has four side surfaces formed from a cylindrical bag body, and two opposing surfaces (corresponding to the gusset folding portions 2 and 4) face the center (folding vertex Z). It has a structure that is folded inward. The disposable diaper bag 10 can be formed of, for example, a polyolefin film such as PE or PP, or a composite material thereof. When the internal capacity is less than 1 to 3 kg, the thickness is 40 μm or more and the tensile strength is 8 N / cm or more. When the internal volume is 3 to 5 kg, it is preferable to use a material having a thickness of 50 μm or more and a tensile strength of 12 N / cm or more.
A direction L connecting both ends 1a and 1b (3a and 3b) of each plane portion 1 and 3 is referred to as a “lateral direction”. Further, in the disposable diaper bag 10, the side where the following seal portion 7 is formed is referred to as “upper end”, and the open end side opposite to the upper end is referred to as “lower side”.

The upper end side of each flat portion 1, 3 is sealed S at two locations parallel to the lateral direction L (specifically, near the upper end edge and two locations below the upper end edge). Part 7 is formed. Further, in the seal portion 7, a central portion B between both ends 1a, 1b (3a, 3b) is cut out to form an oval handle 6 which is long in the lateral direction L.
On the other hand, perforations 8 and 9 penetrating the flat surface portions 1 and 3 and the gusset folding portions 2 and 4 are formed below the seal S (seal portion 7) and along the lateral direction L. However, in this embodiment, since the perforation is not formed in the lower part of the handle 6 (central part B), the perforation 8 formed at the position A1 on the left side of the central part B and the right side of the central part B And perforation 9 formed at position A2.

In this embodiment, the perforations 8 and 9 are formed at positions separated from the both ends 1a and 1b (3a and 3b) by a distance Y in the lateral direction L, respectively. In this case, the disposable diaper package in which the disposable diaper is accommodated in the disposable diaper bag 10 is pulled and pulled from the cardboard case as compared with the case where the perforations 8 and 9 are formed from both ends 1a and 1b (3a and 3b). When taking out, the perforations 8 and 9 can be prevented from being accidentally broken from both ends 1a and 1b (3a and 3b).
The distance Y is preferably about 5 to 10 mm.

FIG. 2 shows a top cross-sectional view when the disposable diaper bag 10 is unfolded. As described above, the perforations 8 and 9 are formed through the flat portions 1 and 3 and the gusset folding portions 2 and 4 with the gusset folding portions 2 and 4 being folded between the flat portions 1 and 3. Yes. Accordingly, when the disposable diaper bag 10 is expanded, perforations 81 and 83 are formed in the flat portions 1 and 3 corresponding to the position A1, and the gusset folding portion 2 extends from the folding vertex Z to both ends 1a and 3a. Two perforations 82a and 82b are formed. Similarly, perforations 91 and 93 are formed in the flat portions 1 and 3 corresponding to the position A2, and two perforations 92a and 92b from the folding vertex Z toward both ends 1b and 3b are formed in the gusset folding portion 4. Is formed.
As shown in FIG. 1, in this embodiment, the end of each perforation 8, 9 extends beyond the folding vertex Z toward the center B side. For this reason, the perforations of each gusset folding part 2, 4 are continuous at the folding vertex Z. On the other hand, when the ends of the perforations 8 and 9 are formed on both ends 1a and 1b from the folding vertex Z, the perforations of the gusset folding portions 2 and 4 are not formed in the vicinity of the folding vertex Z. Any of these may be used, but the latter is stronger.

FIG. 3 shows a disposable diaper package 100 in which a disposable diaper bag 10 is accommodated in a disposable diaper bag 10 in which a plurality of folded disposable diapers 51, 52. The disposable diaper bag 10 is unfolded to form four side surfaces 1 to 4. Further, gable roof-like inclined surfaces 1k and 3k are formed from the flat portions 1 and 3 toward the seal portion 7, and the perforations 8 and 9 are provided on the inclined surfaces 1k and 3k. On the other hand, the gusset folding parts 2 and 4 form inclined surfaces 2k and 4k (only 4k is shown) toward the inside at positions corresponding to the inclined surfaces 1k and 3k.
In addition, after accommodating the diaper laminated body 50 from the lower side (open end) of the bag 10 for disposable diapers, this lower side is sealed and the disposable diaper package 100 is manufactured.

FIG. 4 shows an enlarged view of the perforations 8 and 9. In general, the perforation is formed by repeatedly forming a cut portion C cut into a slit shape and a bond portion D that is located between adjacent cut portions C and is not cut. In the present invention, in the perforations 8 and 9 excluding the lower part of the handle 6 (central part B), (the length in the lateral direction L of the cut part C / the length in the lateral direction L of the bond part D) The represented ratio is preferably 1/3 to 2/1. When the ratio is less than 1/3, the bond portion D becomes too long, and the perforations 8 and 9 may be difficult to break. On the other hand, if the ratio exceeds 2/1, the cut portion C becomes too long, and the perforations 8 and 9 may break carelessly.
The ratio is more preferably 2/3 to 1/1.
As a specific example, the length of the cut portion C in the lateral direction L is 2 mm, and the length of the bond portion D in the lateral direction L is 3 mm.

Next, with reference to FIG. 5, the aspect which opens the disposable diaper package 100 is demonstrated. First, the perforations 8 and 9 formed on the flat portion 1 side of the disposable diaper package 100 (disposable diaper bag 10) are broken (FIG. 5A). Specifically, only the perforations 81 and 91 formed on the flat surface portion 1 and the perforations 82a and 92a of the gusset folding portions 2 and 4 adjacent to the flat surface portion 1 are broken (FIG. 5B). At this time, it is preferable to tear the perforations 8 and 9 at the corners of both ends 1a and 1b of the plane portion 1 as starting points. In this way, it is possible to split up to both sides of the central part B of the plane part 1.
Next, the central portion B of the flat portion 1 is broken in the lateral direction L with scissors and hands (FIG. 5C). If the film has a thickness of 50 to 70 μm and has a tensile strength of up to about 25 N / cm, it can be cut relatively easily by hand. In this way, the flat surface portion 1 is separated from the seal portion 7, and the upper surface on the flat surface portion 1 side (front side) of the disposable diaper package 100 is opened (FIG. 5D).

When the handle 6 is pulled up, the perforations 82b and 92b located on the flat portion 3 side of the gusset folding portions 2 and 4 are broken (FIG. 5E). Here, since the disposable diaper package 100 normally has a weight of about 1 to 4 kg, the perforations 82b and 92b can be easily broken simply by pulling the handle 6 upward. Further, when the handle 6 is pulled up, the stress concentrates on the connecting portion (= folding vertex Z) between the perforations 82a and 92a and the seal portion 7 which have already been broken in FIG. For this reason, unless the lifting force of the handle 6 is excessive, the perforations 83 and 93 (see FIG. 5 (f)) of the flat surface portion 3 are not broken, and only the perforations 82b and 92b can be broken. .
In this way, the flat surface portion 1 and the two gusset folding portions 2, 4 are separated from the seal portion 7, and the upper surface of the disposable diaper package 100 is opened with the maximum size (the same size as the cross-sectional shape) (FIG. 5 (f )). On the other hand, since the flat portion 3 remains integral with the seal portion 7, the handle 6 of the seal portion 7 can be hooked on a hook 200 or a door knob of a basket car and used as a garbage bag with a wide opening. . If the paper diaper bag is made of a relatively thick and milky white film, the filth of the used paper diaper is difficult to see through and is suitable for use as a treatment bag.

As described above, the perforations 8 and 9 passing from the both ends 1a and 1b (3a and 3b) of the flat surface portion 1 (3) toward the central portion B and passing through the flat surface portions 1 and 3 and the gusset folding portions 2 and 4 are provided. On the other hand, by not providing a perforation in the lower part of the handle 6 (central part B), when the disposable diaper package 100 is transported or the like, even if the perforations 8 and 9 are accidentally broken, When the portion B remains without breaking and the disposable diaper package 100 is opened, if the central portion B is broken with scissors or hands, it can be easily used as a garbage bag.
In this respect, it is preferable that the length in the lateral direction L of the central portion B (the handle 6) is 50 to 70 mm. When the length of the central portion B is less than 50 mm, when the disposable diaper package 100 is transported, the central portion B is easily broken as the perforations 8 and 9 are broken by mistake. On the other hand, when the length of the central portion B exceeds 70 mm, when used as a garbage bag, the length of breaking the central portion B with scissors or hands becomes long, and the operation tends to be complicated.

In addition, as shown in FIG. 6, it is good to provide the guidance display part 13 in the predetermined position of the center part B between the perforations 8 and 9 so that a user can recognize easily the part fracture | ruptured with scissors or a hand. In this embodiment, the guidance display unit 13 is composed of an explanatory text “Please cut this part with scissors or the like” on the flat surface parts 1 and 3 and a part displaying scissors or a part to be broken by hand with scissors. ing.
In the embodiment, the second guidance display portions 14 and 15 having an explanatory note “please open along the perforations” are also provided on the perforations 8 and 9.

In the above-described embodiment, the perforation is not formed in the central portion B, but the perforation may be formed in the central portion B. However, in that case, the ratio of the cut portion of the perforation in the central portion B is made smaller than the ratio of the cut portions of the perforations 8 and 9. As a result, the perforation at the center B is less likely to break than the perforations 8 and 9 at both ends, so that when the disposable diaper package 100 is transported, even if the perforations 8 and 9 are accidentally broken, It becomes easy to remain without breaking.
When the perforation is formed in the central portion B, the ratio represented by (the length of the cut portion / the length of the bond portion) in the perforation of the central portion B is set to 1/3 or less, and the perforations 8 at both ends are formed. , 9 should be larger than 1/3.

  It goes without saying that the present invention is not limited to the above-described embodiments, and extends to various modifications and equivalents included in the spirit and scope of the present invention.
