Description

  The present invention relates to a package that stores articles and a packaging bag used for the package.

  Conventionally, absorbent articles such as disposable diapers, training pants, sanitary napkins, panty liners (falling goods sheets), incontinence briefs, and roll toilet paper are stored in a packaging bag made of synthetic resin film material. Various packages are known. There are various forms of the package, but a typical one includes a rectangular parallelepiped package body for storing articles and a planar handle portion extending therefrom. Specifically, the side of the tubular film is gusseted to form a gusset, and the gusset is deeply folded inward at the upper end of the storage body to form a handle by stacking the film ( Patent Documents 1 and 2).

Hereinafter, the packaging body of the present invention will be described in detail with reference to the drawings based on preferred embodiments thereof.
FIG. 1 is a partially cutaway perspective view schematically showing a package 100 according to an embodiment of the present invention together with an article (disposable diaper 20) therein. FIG. 2 is a partially enlarged perspective view schematically showing a state in which the handle portion 7 of the package shown in FIG. The package 100 according to the present embodiment is formed by storing a plurality of disposable diapers 20 in a packaging bag 30 and sealing them. The packaging bag 30 has a main body 6 that houses a diaper and a rectangular handle portion 7 that extends continuously through a base line 9 on the main body 6. On the other hand, a plurality of disposable diapers 20, which are elastic plate-like articles, are arranged in the package body 6 with their thicknesses oriented in the extending direction of the base line 9. At this time, the diaper 20 is preferably in a housed state in which a compressive force is received in its thickness direction, which will be described in detail later with reference to FIG. The article stored in the packaging bag 30 is not limited to the disposable diaper 30, and may be, for example, an elastic plate-like article folded into a plate shape such as incontinence pants or sanitary goods, or roll-shaped toilet paper Arbitrary articles can be adopted as long as a plurality of articles are collected and stored in a packaging bag, such as a granular material such as a pet food.

  In the present embodiment, the package body 6 includes a front surface 1, a rear surface 2, a pair of side surfaces 3 (left side surface 3 l, right side surface 3 r), a bottom surface 5, and a top portion in a state where a plurality of superposed disposable diapers 20 are accommodated. 4 and a rectangular parallelepiped. In the present embodiment, unless otherwise specified, the “front-rear direction” means a direction x connecting the front surface 1 and the rear surface 2, and the “left-right direction” means a direction connecting the pair of left side surfaces 3 l and the right side surface 3 r. y means “up and down direction” means a direction z connecting the top 4 and the bottom 5. In the center of the handle portion 7 in the left-right direction y, a grip region (a grip hole 8) is formed so that the hand 100 can be gripped when the package 100 is lifted. In the present invention, the “cuboid” or “rectangular shape” is not limited to a rectangular parallelepiped or a rectangle, but includes a thing that can be functionally regarded as a cuboid as a whole. For example, each surface, each side or each vertex is slightly bent, chamfered with slightly rounded corners, given processing, or other members attached Including those with slightly modified shapes. In the present embodiment, the top part 4 constituting the main body 6 is not arranged in parallel with the bottom surface, and as shown in FIG. It is considered as a packaging form. Further, when the side surface 3 is viewed, a portion continuous from the side surface 3 that is gusset-folded as described later is inward so that the base end (9l, 9r) at the top of the top side that becomes both ends of the base line 9 is formed. The front surface 1 and the rear surface 2 are sandwiched between the folds. In this way, the ceiling 4 is generally composed of four surfaces, that is, a ceiling front surface 41, a ceiling rear surface 42, and right and left ceiling side surfaces 43.

  In the present embodiment, the packaging bag 30 is formed of one tubular film so that the main body 6 and the handle portion 7 are continuous via the base line 9 (see FIGS. 1 and 7). The constituent material of the packaging bag 30 can be a normal material applied to this type of product, and is not particularly limited, but it is preferable to use a film of polyethylene, polypropylene, PET or the like. Although the thickness is not particularly limited, for example, it is practical to use a film layer constituting the packaging bag 30 having a thickness of about 20 to 100 μm. In addition, the bonding method for forming the sheet-like handle 7 integrally above the base line 9 is not particularly limited, and a method usually applied to sealing of this type of package can be used, for example, heat sealing It can be bonded by the method.

In the present embodiment, as described above, the handle portion 7 extends continuously via the base line 9 on the top portion 4 of the main body 6, but the base line 9 extends from the handle portion 7 to the top portion 4. A base line rigid region 10 is formed so as to straddle (see FIGS. 1 and 2). In other words, the base line portion rigid region 10 is divided into a rigid upper portion 10a that extends from the base line 9 toward the handle portion 7 and a rigid lower portion 10b that extends from the base line 9 toward the top portion 4 (FIGS. 1 and 2). reference). The “rigid region” means a region in which the rigidity of the packaging bag 30 formed of a soft film material is higher than that of other regions. In the present embodiment, the base line portion rigid region 10 extending over both members across the base line is formed in this manner, so that shape restoring property is imparted to the film material of the portion, and the state is strongly pressed and folded. Is maintained over a long period of time, and returns to its original shape, and the rigid upper portion 10a rises while leaving the rigid lower portion 10b. Details will be described later. The rigidity of the base line portion rigid region 10 is preferably 1 to 25 gf and more preferably 5 to 15 gf when the curvature radius is 0.5 ⁻¹ cm.

  The formation of the baseline portion rigid region 10 is preferably performed by embossing. The embossing produces a concavo-convex shape in which the film is patterned, and the rigidity is improved. For embossing, a normal one applied to this type of product can be used, and is not particularly limited, but hot embossing or ultrasonic embossing is preferable. The heating during embossing is preferably performed at a temperature that exceeds the softening point of the film material and does not exceed the melting point. If the softening point of the film material is exceeded, the shape retention by embossing will be sufficient, and if the melting point of the film material is not reached, the film materials will not be fused together and the flexibility will not be impaired, and the film material will be perforated or torn. Is preferably suppressed.

  In the present embodiment, the baseline portion rigid region 10 is preferably formed in the vicinity of both ends 9 l and 9 r of the baseline 9. Thereby, when the upper part 10a of the base line part rigid region 10 rises by the restoring action described above, it is preferable that a finger can be easily inserted into the gap Q between the handle part 7 and the main body 6 formed there. From such inspection points, the base line rigid region 10 is preferably provided in the range of 0 to 80 mm from both ends 9l and 9r of the base line 9, and more preferably 10 to 40 mm.

  Here, the conventional situation and the idea in the present invention will be described in detail. Generally, a film material generally used for a package cannot obtain high rigidity only by being sealed, and the handle portion located at the upper part of the package is naturally shaped and easily falls into the main body. In particular, in recent years, the tendency to reduce the thickness of the film material from the viewpoint of cost reduction of the package manufacturing cost and consideration of environmental problems is also promoted. In particular, in transport packaging in which a plurality of packaging bodies are packed and packed in cardboard or the like without gaps, the handle portion is pressed against the top of the main body and the films are in close contact with each other. In this state, the original function of carrying the package cannot be smoothly exhibited, and when the package is taken out and displayed at the storefront, the handle is peeled off from the storage body one by one. The work must be started up. Moreover, since the said handle part will fall into the top part of a package body in the natural state also at the time of display, since it will also be difficult to take out from a display shelf, it becomes a factor which inhibits purchase promotion. However, none of the conventional packaging bodies has a structure that allows the handle portion to stand up from the packaging body body, and thus cannot solve the problems caused by such collapse.

  According to the present invention, the above situation is improved. This will be described with reference to FIG. 3 showing the shape restoring action of the base line rigid region 10 of the present embodiment. According to the present embodiment, since the base line portion rigid region 10 is formed, a combined state is hardly generated when the facing rigid upper portion 10a and the rigid lower portion 10b are in contact with each other. The rigid lower portion 10b behaves like a solid scaffold and serves as a foundation, and the rigid upper portion 10a is gradually raised by its spontaneous shape restoring force (see FIGS. 3B and 3C). Therefore, even if the handle portion 7 falls and bends into the main body 6 and is strongly pressed during the transportation or the like, the rigid upper portion 10a naturally returns to the original shape in the baseline portion rigid region 10. As a result, the rigid upper portion 10a and its periphery rise naturally from the handle portion 7 simply by being displayed at a store, for example. However, the shape of the illustrated one is exaggerated for the purpose of explanation, and the present invention is not construed as being limited by the standing state.

  In this way, a gap Q is formed between the base 6 of the handle portion 7 and the main body 6 at both left and right ends. A finger can be easily inserted into that portion, and the entire handle portion 7 is pulled up. The package 100 can be carried with a palm. In addition, according to the present embodiment, the above-described action of naturally restoring the shape is realized without the need for special members or processing. Therefore, not only is the manufacturing efficiency high, but it is not overpacked and discarded. It also matches the packaging suitability suitable for sorting.

Furthermore, in addition to the baseline portion rigid region 10, the handle portion 7 in the present embodiment is formed with a handle portion rigid region 11 spaced apart from the baseline portion rigid region 10 (see FIG. 2). ). The handle portion rigidity region 11 has a higher rigidity than the periphery thereof in the same manner as the base line portion rigidity region 10. Thereby, as described above, when the root of the handle portion is raised through the shape restoring action of the base line portion rigid region 10, the portion toward the end edge 45 of the handle portion does not sag outside and is good. A gap Q having an open shape is secured (see FIG. 3C). From this point of view, it is preferable that the grip portion rigid region 11 has substantially the same height as the grip hole (gripping region) 8 when the grip portion hole 8 is gripped and the main body is lifted. Here, “substantially the same height” means that it may be a region that is biased up and down as long as it includes the center position t ₁ in the height direction of the gripping hole (grip region) 8. .

The distance S between the height-direction center position _{t 1} in the height direction position _{t 2} and gripping bore baseline 9 is not particularly limited, is preferably from 10 to 30 mm, and more preferably 15 to 25 mm. The distance R between the base line portion rigid region 10 and the handle portion rigid region 11 is not particularly limited, and may be continuous as long as they are functionally differentiated. It is practical to use 10 mm. In addition, the height T of the package body 6 is not particularly limited as long as it is usually the length of this type of package body.

The area of the base line rigid region 10 or the handle portion rigid region 11 is not particularly limited, but considering the good self-standing property and the gap securing property at the base of the handle portion 7, the area should be 50 to 400 mm ^2. Is more preferable, and 100 to 200 mm ² is more preferable. In the baseline portion rigid region 10, the ratio (Ma / Mb) of the area Ma of the rigid upper portion 10a and the area Mb of the rigid lower portion 10b is preferably 0.5 to 2.0, and 0.8 to 1.2. Is more preferable.

  As described above, the base line portion rigid region 10 is preferably provided in the vicinity of both ends of the base line 9. However, as the region, the base line portion rigid region 10 is provided in the four-layer structure region H which is sealed by gusset folding of the handle portion 7. It is preferable (refer FIG. 2). A method for forming the four-layer structure region will be described later. Here, film sheets constituting the packaging bag are laminated in four layers. However, in the present embodiment, the base line portion rigid region 10 is formed only on one layer of the four layers of film that is continuous with the front surface 1 of the main body. The base line portion rigid region 10 and the handle portion rigid region 11 may be arranged only on one side of the planar handle portion 7 instead of the present embodiment. Further, it may be arranged not on the front side of the top but on the rear side of the top, or may be arranged on both the front side of the top and the rear side of the top. Furthermore, the following other modifications are mentioned.

  FIG. 4 is a partially enlarged perspective view schematically showing another embodiment (Embodiments 2 and 3) of the baseline portion rigid region 10 in the present invention. In the second embodiment, the base line portion rigid region 10 is formed along the direction in which the base line 9 extends, as shown in FIG. In the case of heart-shaped embossing, it is desirable to use the upside down arrangement shown in FIG. 4A or other oblique arrangement because the area of the rigid upper portion 10a of the base line portion rigid region 10 can be easily increased and the rigidity is further increased. In the baseline portion rigid region 10 in the third embodiment, cross-shaped surface embossing shown in FIG. 4B is formed in the same manner as described above. In the case of cross-shaped embossing, it is more rigid in the base portion rigid region 10 that the intersection shown in FIG. 4B overlaps the base line 9 or the other one is parallel to and passes through the base line 9. This is desirable because the area of 10a can be easily increased and the rigidity can be further increased. The base line portion rigid region 10 in the second and third embodiments is formed across the base line 9, and can maintain the effect of increasing the rigidity and have a design. The shape is not limited to this, and any shape can be used. In the second and third embodiments, the two base line rigid regions 10 are formed in alignment along the direction in which the base line 9 extends, but the number thereof may be three or more. By providing the plurality of base line rigid regions 10 in this way, the range over which the effect of the rigid regions is substantially expanded, and the package 100 by the shape restoring force of the handle portion 7 is not affected by the compression state. The liftability of the can be further improved.

  FIG. 5 is a plan view schematically showing an example of point emboss forming a rigid region. The base line portion rigid region 10 shown in FIG. 5 does not have the entire rigid region as one surface emboss, but a plurality of small circular point embosses 12 are arranged in a predetermined pattern in the rigid region. In this case, the outer edge of the assembly of the embosses 12 defines the range of the rigid region formed across the base line 9. By forming the baseline rigid region 10 composed of such point embossing, the embossed region becomes inconspicuous and the tactile sensation is also improved. Moreover, even if one point of the embossed part does not generate rigidity by being constituted by point embossing, rigidity is generated by another embossed part, so that stable rigidity can be maintained.

FIG. 6 is a plan view schematically showing an example of line embossing that forms a rigid region. The base line portion rigid region 10 shown in FIG. 6 includes a line emboss 13 (FIGS. 6A and 6B) having the entire rectangular shape as one emboss, or a line emboss 13 having the entire arcuate shape as one emboss (FIG. 6 ( c)) is formed across a base line 9 to form one region. By forming the baseline rigid region 10 composed of such line embossing, the rigid region becomes inconspicuous and the tactile sensation is also improved. From the viewpoint of increasing rigidity, the line embossing is preferably not parallel to the base line 9, and more preferably perpendicular. The plurality of line embosses 13 to point embosses 12 need only straddle the base line 9 as the base line rigid region 10 as a whole, and the individual embosses do not have to straddle the base line 9.
It does not have to be.

With reference to FIG.7 and FIG.8, the formation process of the packaging bag 30 and the procedure which accommodates the subsequent disposable diaper 20 as a package body are demonstrated.
In the present embodiment, the packaging bag 30 (see FIG. 1) is formed using a tubular film 30A that is continuously fed as a raw material. FIG. 7 shows a process from the tubular film 30A through the packaging bag intermediate (1) 30B to the production of the packaging bag intermediate (2) 30C until the packaging bag handle 7 is formed ( In the figure, for the sake of understanding, a perspective view of one bag corresponding to the perspective view shown in FIG. 1 is shown. However, in actuality, a film further extends beyond the handle portion 7, while the reverse is the bottom. The portions that become the same may be continuous, and a plurality of packaging bags may be manufactured continuously.) In the tubular film 30A, the side surface of the tube is valley-folded inwardly along the valley fold lines m ₁ and m ₂ to form a gusset fold 3A (see FIGS. 7A and 7B). At this time, the base line portion rigid region 10 and the handle portion rigid region 11 are provided on one surface of the tubular film 30A (before the handle portion is formed, but the signs of the rigid regions 10 and 11 are not understood. And the name will be described without replacement.) Next, in the packaging bag intermediate (1), the tip line 45A is brought close to each other in the direction n so as to sandwich the gusset folding portion 3A in the top front planned portion 41A and the top rear planned portion 42A (see FIG. 7 (b) (c)).

Thereafter, the region on the tip line 45 side from the base line 9 is entirely joined by heat sealing or the like to form the handle portion 7 (see FIG. 7C). At the same time, an oblong holding hole 8 extending in the left-right direction y is formed in the center of the handle portion 7. In the handle portion 7, a portion located laterally outward of the valley fold lines m ₁ and m ₂ is a four-layer structure region H in which four layers of films are laminated as described above.

In the packaging bag 30 of the present embodiment, the opening (bottom surface planned portion 5A) located on the opposite side of the packaging bag intermediate (2) 30C having the handle portion 7 formed as described above is opened. The disposable diaper 20 is accommodated from there (see FIG. 8). In the present embodiment, the diaper 20 has a shape folded at the crotch part C so that the back side F and the abdomen side R of the unfoldable diaper face each other. In the embodiment shown in FIG. 8, the disposable diaper 20 folded in a plate shape is arranged so that 10 sheets (20A to 20J) overlap each other in the thickness direction, thereby constituting a polymer 20Z of a plate diaper as a whole. Yes. Compressing the plate-like diaper polymer 20Z in the thickness direction (see step P _1), a somewhat smaller state than the natural shape overall, the bottom scheduled portion 5A of the opened packaging bag intermediates, towards the top part 4 Inserted. At this time, the packaging bag with the crotch part C, which is the folded portion in which the absorbent body is located, facing the top part 4 with the direction extending in the planar shape of the plate-like diaper parallel to the side surface 3 (3l, 3r) of the main body 6 installed inside of the intermediate 30C (see step _{P 2).} Then, (see step P ₃₎ solving the above compression, storage state is obtained that pressure broaden stable some packaging bag intermediates than inwardly while bulge diaper (1) 30C to the left and right sides. Further, the planned bottom portion 5A is folded and bonded in a caramel packaging shape to form a packaging bag 30 (see FIG. 1).

In this embodiment, it should be further noted that the aligned state of the diaper polymer 20Z accommodated through the above-described process is slightly collapsed, and usually the side surface planned portion 3A as shown in FIG. 8 (b). There is a tendency that the one close to is inserted shallower than the central one. In other words, it is harder to be inserted deeper as it is compressed (process P ₁ ) on the outer sides of both sides (20A, 20J and those close thereto). The reason for this is that when the crotch part C of the diaper is compressed because it is thicker (step P ₁ ), the polymer 20Z as a whole tends to be curved slightly on the arch, It is easy to receive resistance by contact with the planned side surface portion 3A of the body 20C. Then, the space G is formed in the direction of the top part of the diapers 20A, B and the diapers 20I, J on both the left and right sides of the top part 4A of the top part of the packaging bag intermediate body, that is, both ends in the polymerization direction of the diaper polymer 20Z. It will be.
Normally, the space G does not disappear even when the packaging bag 30 is formed. When a packaging bag is put in a cardboard or the like, there is a concern that the base portion rigid region 10 may be crushed by being compressed from above, but since the space G exists, the base portion rigid region 10 is not crushed, and corrugated cardboard or the like. Good self-standing characteristics are exhibited even when taken out from the container.

  In the packaging body 100 in the above-described embodiment, the diapers 20 are shown as aligned in one row. However, the packaging body 400 is not limited to this, and may be a two-stage and two-row packaging body 400 as shown in FIG. . Also in such an embodiment, according to the present invention, the above-described favorable operational effects can be obtained.
