Description

  The present invention relates to a bag filled with a powdery substance such as a powder detergent and suitable as a refill bag used in a box-shaped container.

  As a refill bag filled with granular or powdered powdery substances such as powder detergent, the bottom has a gusset, the top is a flat bag type, and the width of the outer method of the bag is the bottom end with respect to the top end There is a narrow reverse taper type film bag filled with a powdery substance. This bag is used by being housed in a box-shaped container having a box-shaped container body having an opening on the upper surface and a lid covering the opening of the container body.

  When the upper portion of the bag is torn while the bag is placed in the container body, the bag opens over its entire width, and the opened bag is pressed against the inner wall of the container body by the powdery substance in the bag. Therefore, a bag becomes a box shape along the inner wall of a container main body, and opens widely (patent document 1).

JP 2012-240688 A

  The refill bag accommodated in the above-mentioned box-shaped container is opaque because the box-shaped container is generally formed of cardboard or the like, and the bag itself is opaque for printing product information or the like. From the appearance of the box-shaped container, the remaining amount of the powdery substance in the bag cannot be known. In addition, when using the powdery substance in the bag with the lid of the box-shaped container open, the bag has a box shape along the inner wall of the container body, so the remaining amount is small enough to see the bottom. Otherwise, consumers are less likely to notice that the amount of powdered material is low. Therefore, the consumer knows that the refill bag to be used next should be prepared when the remaining amount in the bag becomes small and the bottom surface of the bag starts to be seen. There may be cases where the replacement bag is not ready.

  On the other hand, it is conceivable to print scales, characters, or the like indicating the remaining amount of the powdery substance on the inner surface of the film forming the body of the refill bag. However, because the outer surface of the film forming the body is printed with product information or decorative printing, the outer surface is printed even if a display indicating the remaining amount of the powdery substance is given on the inner surface of the film. It is difficult to understand because it shows through.

  As a method for preventing the printing on the outer surface of the bag from being seen through when the inner surface of the refill bag is viewed, a light shielding layer is formed between the outer surface printing and the inner surface printing of the bag as a film forming the bag. Although it is possible to use what has this, the material cost of a bag becomes high.

  On the other hand, for example, it is possible to print information that inspires consumers to purchase on a refill bag due to an amusement effect, such as a lottery whose product appearance does not indicate “win” or “miss”. This is useful from the viewpoint of sales promotion of replacement bags.

  Therefore, the problem to be solved by the present invention is that the information regarding the remaining amount of the powdery substance in the refill bag, the information having an amusement effect, etc. are clear and timely, and the material cost is not increased. It relates to making it easy to communicate to consumers.

  The inventor can omit printing of product information and decoration printing on the outer surface of the film forming the gusset, unlike the outer surface of the film forming the body portion, in the above-described refill bag, and therefore If a display indicating the remaining amount of the powdery substance is provided on the inner surface of the gusset-forming film, it is possible to make the display easier to see. In the container body of the box-shaped container, the triangles on both sides of the gusset Since the display area rises along the side surface of the container body, if the display indicating the remaining amount of the powdery substance, etc. is provided on the inner surface of this triangular area, the remaining amount of the powdery substance becomes so large that the bottom of the bag can be seen. Before it became small, consumers found it easier to notice that the remaining amount of powdered material was decreasing and came up with the present invention.

That is, the present invention relates to a film-made packing filled with a powdery substance, which is accommodated in a box-shaped container having a box-shaped container body having an opening on the upper surface and a lid covering the opening of the container body. A replacement bag,
It has a gusset at the bottom of the bag, the top of the bag is a flat bag type, both sides of the gusset and the bag body are sealed by an oblique seal that is inclined with respect to the bottom end of the bag, and the outer width of the bag Has a narrow reverse taper shape at the bottom end with respect to the top end,
Provided is a bag in which characters, symbols or figures are displayed in at least a triangular region adjacent to the oblique seal portion on the inner surface of the gusset bag.

  According to the bag of the present invention, information on the remaining amount of the powdery substance in the bag, information for prompting the preparation of the next refill bag, amusement such as a lottery, on the inner surface of the gusset bag by characters, symbols or figures Information having a special effect can be displayed. Since printing of product information and decorative printing can be omitted on the outer surface of the gusset bag, the display of the inner surface of the gusset bag according to the present invention can be made clear from the inner side of the bag. In this case, printing of product information and decoration printing can be arbitrarily performed on the outer surface of the bag body. Moreover, as a film which forms a gusset, the general thing without a light shielding layer can be used.

  With the bag in the container body of the box-shaped container, the triangular areas on both sides of the gusset stand up along the side of the container body, so that the powdery substance in the bag is slightly more visible as the bottom of the bag is visible. The triangular areas on both sides of the gusset are observed before becoming.

  Therefore, it is possible to inform the consumer in a timely manner that the amount of the powdery substance in the bag has decreased while using a general film for forming the gusset.

  In addition, when information having an amusement effect such as a lottery with “winning” and “out” is written on the inner surface of the gusset bag, the information indicates that the pulverized substance contained in the refill bag is the gusset. Since it appears in front of consumers for the first time after consumption so that the triangular areas on both sides can be seen, consumers will often consume powdered substances, and can promote sales of refill bags .

  Hereinafter, the present invention will be specifically described with reference to the drawings. In addition, in each figure, the same code | symbol represents the same or equivalent component.

  FIG. 1 is a perspective view of a film bag 10A filled with a powdery substance according to an embodiment of the present invention. FIG. 2 shows a front view (1), an AA view (2), and a BB view (3) of the bag 10A in a state in which the powdery substance is not filled for convenience of explanation.

  As shown in FIG. 2, in this bag 10A, a pair of front and back film sheets forming the bag body are sealed with side seals 12, and a film forming the bottom gusset 11 and a film sheet forming the bag body are formed. It is sealed with a hem seal 14 and its upper end is sealed with a top seal 13 having a wide seal width. The width L1 of the top seal 13 is preferably 10 mm or more so that the top seal 13 is picked and the bag 10A is easily torn from the side seal 12 at the top of the bag.

  On the bag bottom side of the side seal 12 on both sides of the bag 10A, both sides of the gusset 11 and the bag body are sealed with a band-like oblique seal portion 12a inclined with respect to the bottom end of the bag 10A. The angle θ between the edge of the oblique seal portion 12a and the extended line of the bottom end is preferably 40 ° or more and 50 ° or less, more preferably 45 °. Thus, since the outer shape of the bottom portion of the bag 10A is rectangular, when the bag 10A is accommodated in the container main body 2 of the box-shaped container 1, the outer shape of the bag 10A can be well adapted to the inner shape of the container main body 2. (See FIG. 4A). Note that the side of the side seal 12 can be linearly formed to the bottom end as in the so-called ship bottom type seal, but on the bag bottom side where the oblique seal 12a is formed as in the bag 10A. By not sealing the front and back films forming the body part, the bottom of the bag 10A can easily spread in a box shape, and the outer shape of the bag 10A can easily follow the inner shape of the container body 2 (see FIG. 4A). Further, in the bag 10A, when the bag-like substance is filled into the bag 10A by the hem seal 14 at the bottom end, the gusset 11 at the bottom of the bag 10A spreads in the thickness direction of the bag 10A, so that the refill bag itself is self-supporting. Is stable.

  Characters, symbols, or figures are displayed in at least the triangular area 11a (area marked with dots in FIG. 1) adjacent to the oblique seal portion 12a on the inner surface of the gusset 11 bag. These indications may be formed on the entire inner surface of the gusset 11 bag. On the other hand, the outer surface of the bag of the gusset 11 is plain on which characters, symbols, figures, etc. are not displayed.

  The triangular region 11a of the gusset 11 rises along the side surface from the bottom of the container body 2 when the bag 10A is accommodated in the container body 2 of the box-shaped container 1. Therefore, the triangular region 11a on the inner surface of the gusset 11 is not visible even when the bag 10A is observed from the inside in a state where the powdery substance in the bag 10A is sufficiently filled, but by using the powdery substance, As the remaining amount decreases, it gradually appears and the area that appears also increases. Therefore, it is preferable that at least one of the triangular regions 11a of the gusset 11 on the inner surface of the bag includes a display regarding the remaining amount of the powdery substance or a display prompting the preparation of the next refill bag. As an example of such a display, for example, a repetition of a character string such as “refill” for prompting the preparation of the next refill bag shown in FIG. 6A can be given. As shown in FIG. 6B, since the use of the refill bag reduces the environmental burden, a repetition of a character string such as “eco” that indirectly prompts for the preparation of the refill bag may be displayed. As shown in FIG. 6C, the user may be prompted to prepare a refill bag, display precautions when using a box-shaped container, or display related product guidance. You may display a scale, the number of remaining use, etc. In addition, it has amusement effects such as “winning” and “losing” of lottery with indications regarding the remaining amount of powdery substances, indications prompting the preparation of the next refill bag, or separately from these indications. Information may be displayed.

  The background color of the above-mentioned display on the inner surface of the gusset 11 is preferably a color that is different from the powdery substance and the appearance of the triangular region 11a is conspicuous. For example, when the powdery substance is white, the background color of the inner surface of the gusset 11 is set to a high density color or the like.

  The upper part of the bag 10 </ b> A has a flat bag shape due to the top seal 13 and the side seal 12. Therefore, as shown in FIG. 2, the outer width W1 of the bag 10A at the bottom end is narrower than the outer width W2 of the bag at the upper end of the bag 10A, and the bag 10A is filled with a powdery substance. Then, as shown in FIG. 1, the width of the lower end is narrower than that of the upper end, and the area of the bottom formed by the gusset 11 is made equal to or less than the area of the bottom of the container body 2. Can do. Therefore, when the bag 10A in the container body 2 is refilled, the bag 10A can be easily inserted into the container body 2.

  On the top seal 13, a strip-shaped film reinforcing member 15 is stuck so that the lower side of the top seal 13 and the lower side of the film reinforcing member 15 overlap. This film reinforcing member 15 imparts to the bag 10A straight tearability in the width direction. That is, when the bag 10A is placed in the container body 2 and the top seal 13 is picked up and the bag 10A is torn from the upper part of the side seal 12, the bag 10A is easily torn linearly along the lower side of the film reinforcing member 15. . The straight tearability in the width direction of the bag 10A is also provided by using a film having tear straightness as the film forming the trunk of the bag 10A. In the present invention, the top seal 13 is provided as necessary. Provided.

  The band width L2 of the film reinforcing member 15 is preferably 3 mm or more from the viewpoint of sufficiently obtaining the effect of sticking the film reinforcing member 15. As a film for forming the film reinforcing member 15, films such as OPP (biaxially stretched polypropylene), PET, ONy (biaxially stretched nylon) can be used. These film thicknesses are 30 μm or less from the viewpoint of improving the tear straightness of the opening line when opening the bag 10A and preventing the step between the seal bar and the film when sealing the top seal 13. Preferably, it is 12 μm or more and 50 μm or less.

  The side seal 12 extends in the vertical direction on both sides of the bag 10A, and a notch 23 cut into a V-shape is provided in the side seal 12 at the top of the bag as an opening start portion. In the present invention, an I-shaped notch, a U-shaped notch or the like may be provided as an opening start portion instead of the V-shaped notch.

  The distance L5 between the opening start point (the tip in the opening direction of the notch 23) and the film reinforcing member 15 at the opening start portion is preferably within 10 mm from the viewpoint of improving the ease of opening. It is more preferable. Further, the distance L6 between the opening start point at the opening start portion and the bottom end portion of the bag 10A is such that the opening surface of the bag 10A is the opening surface of the container body 2 when the opened bag 10A is accommodated in the container body 2. Or the difference between the depth of the container body 2 and the distance L6 is 5 mm or more and 0 mm or less so that the opening surface of the bag 10A is located slightly below the opening surface of the container body 2. preferable.

  The circumferential length of the body portion of the bag 10 </ b> A is preferably substantially the same as the circumferential length of the inner dimension of the container body 2. As a result, as shown in FIG. 4A, after opening the bag 10A from the notch 23, the powdery substance P in the bag 10A is about to spread, so that the substantially entire circumferential surface of the bag 10A is the container body 30. Pressed against the inner wall. For this reason, the opening shape of the bag 10A is wide and stable, and the powdery substance P can be easily taken out with the measuring spoon. Here, “substantially the same size” means that the upper end opening of the bag 10A does not fall inside and the upper end of the bag 10A cannot sag in the container main body 2 and the container main body. This means that the inner circumference of 2 is the same.

  Films forming the body of the bag 10A include polyesters such as polyethylene terephthalate, polyamides such as nylon, low density polyethylene (LDPE), linear low density polyethylene (L-LDPE), expanded polypropylene (OPP), unstretched polypropylene ( CPP) and the like can be used, and can be used as a single layer or a laminated film. Among them, a film having straight tearability by stretching or the like is preferable. Particularly, when the film forming the bag 10A is a laminated film including an outer surface layer and / or an intermediate layer and an inner sealant layer, an inner sealant layer and an outer It is preferable that the surface layer and / or the intermediate layer has tear straightness in the width direction of the bag. As the inner sealant layer having straight tearability, linear low density polyethylene (L-LDPE) or the like is preferably subjected to an easy cut process.

  In addition, when using a film having tear straightness, the bag 10A may be used as a whole, but a gusset 11 at the bottom of the bag is formed from the viewpoint of improving the impact resistance of the bottom of the bag against dropping or the like. As the film to be used, it is preferable to use a laminated film having general physical properties (OPP, PET, LDPE, L-LDPE) which does not have straight tearability.

  The thickness of the film forming the body of the bag 10A is preferably 40 μm or more and 200 μm or less, more preferably 100 μm or more and 150 μm or less so that the film has a firmness to the extent that the bag 10A is self-supporting even when there is no content. And Thereby, after opening the bag 10A, the powdery material decreases with the use of the powdery material in the bag 10A, and even if the position where the powdery material presses the bag 10A against the inner wall of the container body 2 is lowered, An open state can be maintained and the ease of taking out a powdery substance can be maintained. Note that the self-supporting property of the bag 10A can also be improved by forming the hem seal 14 at the bottom of the bag 10A as described above.

  7A to 7F are process explanatory views of an example of a bag making method of the bag 10A. First, as shown in FIG. 7A, a film 110 that does not have a straight tearing property for forming the gusset 11 and is provided with an indication regarding the remaining amount of the substance or the preparation of the next refill bag on the inner surface of the bag. Print the display that prompts the bag, and the outer surface of the bag is plain, and the bag is folded in half with the inner surface of the bag on the outside. The long strip-shaped film 100 is stacked. Next, as shown in FIG. 7B, a seal 120 that becomes the side seal 12 and a continuous seal 140 that becomes the hem seal 14 are formed, and as shown in FIG. And squeeze together with a roller. Thereafter, as shown in FIG. 7D, the side seals 12 of the adjacent bags are cut off, the bottom V-cut, and the notch 23 are formed. Thus, the bag 10X shown in FIG. 7E is obtained, and the powdery substance as the contents is filled from the upper end opening of the bag 10X, and then the bag is closed with the top seal 13. Thus, the bag 10A of FIG. 1 can be obtained.

  On the other hand, the container body 2 of the box-shaped container 1 that accommodates the bag 10A can be a rectangular parallelepiped container formed using a paperboard-like material such as a paperboard, a plastic sheet, or a plastic box. Further, the lid 3 of the container body 2 may be anything as long as it covers the upper surface opening of the container body 2. For example, a lid whose one edge is coupled to the back surface of the container body 2 in a hinge shape can be used ( 4A and 4B).

  This bag 10 </ b> A is used as a refill product for using the powdery substance in the box-shaped container 1. Therefore, as a specific method of using this bag 10A, first, an unopened bag 10A filled with a powdery substance is placed in the container body 2 of the box-shaped container 1, and then, as shown in FIG. With the bag body 10A placed on the container body 2, the bag 10A is torn from the notch 23 in the width direction. As a result, the bag 10A is linearly torn across the entire width, the upper end of the bag 10A is removed, and the remaining bag 10A is, as shown in FIG. 4A, the inner wall of the container body 2 by the powdery substance P in the bag 10A. It is pressed as shown by the arrow to open wide. After appropriately taking out the powdery substance P in this state, the opening surface of the container body 2 is closed with the lid 3 as shown in FIG. 4B.

  Thus, when the powdery substance P is taken out from the bag 10A, initially, the gusset triangular area 11a is buried in the powdery substance P and cannot be seen (FIG. 5A). As the remaining amount of the powdery substance P decreases, the triangular area 11a of the gusset 11 appears (FIG. 5B), and the area where the triangular area 11a appears gradually increases (FIGS. 5C and 5D). And the central part of the gusset 11 along the bottom surface of the refill container 2 also starts to appear (FIG. 5E), and the area where the central part of the gusset 11 appears increases (FIG. 5F).

  In the triangular area 11a on the inner surface of the gusset 11 and the central portion of the gusset 11, there is a display regarding the remaining amount of the powdery substance P, a display prompting the preparation of the next refill bag, a display having an amusement effect, and the like. Thus, when the consumer begins to see the triangular area 11a of the gusset 11, the consumer notices this indication and knows that a refill bag to be used next should be prepared. Alternatively, the area in which the triangular area 11a of the gusset 11 can be seen increases, so that the consumer is prompted to prepare a refill bag to be used next. Thus, the consumer can prepare a refill bag to be used next timely. Moreover, when the display which has an amusement effect is displayed on the gusset 11, the consumer can enjoy the display.

  The bag of the present invention can take various forms. For example, the straight tearability imparted to the bag can be easily opened by embossing, half-cutting, or incision formed intermittently in the band-like region along the lower side of the top seal, regardless of the attachment of the film reinforcing member 15. A processing region may be provided.

  In addition, the deformation | transformation aspect of the above-mentioned bag can be combined suitably.

  Examples of the powdery substance to be filled in the bag include granular detergents such as powder detergents, sugars and salts, and powdery substances. The bulk density of the powdery substance is preferably 700 g / L or more in that the powdery substance opens the bag widely by pressing the bag against the inner wall of the container body 2.

  The bag of the present invention is suitable as a refill for powdery substances such as powder detergents.
