Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a paper-made flat envelope serving as a storage bag for a "small gift" or the like for example has a considerably excessive space left on the inner bottom of the bag since both corners of the bottom do not expand and the lower end of a bulky (or thick) article to be stored cannot be inserted to the vicinity of the inner bottom of the bag. <P>SOLUTION: L-shaped notches 6 and 6 extending into a lateral side 1a and a bottom side 1b of a bag body 1 by a predetermined small width are formed on both corners 5 and 5 on the bottom 4 of the paper-made flat envelope-like bag body 1. Thus the entire bag bottom including both corners can be easily expanded, so that the article can be inserted into the vicinity of the inner bottom of the bag. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a storage bag for storing a bulky article such as a folding towel.

  Towels are sometimes used as “participation awards” for events and “crude products” as gifts of regular patronage. When gifting towels as “crude products” etc., for example, as shown in FIG. As in the first conventional example or the second conventional example shown in FIG. 7 to FIG. 10, the towel 9 is provided in a storage bag 50 (or 60) in a state of being folded to an appropriate size. . In addition, when storing in the storage bag as “crude” etc., the towel 9 is folded several times in the length direction and width direction (folded to a total of about 12 to 16 folds). The thickness of 9 is about 25 to 35 mm in the face towel.

  The storage bag 50 of the first conventional example shown in FIG. 6 is made of a transparent plastic film. The towel is folded several times in the length direction and the width direction, and the outer side of the folded towel 9 is wrapped with candy paper 52. It is stored in a plastic film bag 50. In FIG. 6, since the bag 50 is transparent, the candy paper 52 and the folding towel 9 are seen through from the outside of the bag.

  Since the storage bag (plastic film bag) 50 used in FIG. 6 is flexible, the bag bottom 51 can be inflated relatively easily when the folding towel 9 is stored. Is easy to fit the outer surface of the storage. In addition, the plastic film bag 50 is inexpensive and has excellent rupture strength for its flexibility. Therefore, the plastic film bag 50 is frequently used as a storage bag for storing this type of storage item (folding towel 9). . In addition, as a reference example of this type of plastic film bag, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 2000-219245 (Patent Document 1).

  The storage bag of the second conventional example shown in FIGS. 7 to 10 is a flat envelope-shaped paper bag 60. 7 is a plan view of the front side of the paper bag 60, FIG. 8 is a plan view of the back side thereof, FIG. 9 is a plan view of the back side of the paper bag 60 with the folded towel 9 stored therein, and FIG. FIG.

  As shown in FIGS. 7 to 10, when a paper bag 60 is used as a storage bag, a paper material having a considerable thickness in terms of bag breaking strength is used, and a bottom lid material 61 is provided on the bag bottom 60a. Is folded and attached (see FIGS. 8 and 9). Further, a lid piece 64 is continuous with the opening 63 of the bag, but the left and right edge lower ends 64a, 64a of the lid piece 64 are continuous with the left and right outer ends of the opening width of the bag. .

  Further, as an article storage bag, there is a bag provided with gussets 71, 71 and 72 on both sides and bottom of a paper bag 70 as shown in FIG. 11 (third conventional example). A reference example of this type of gusseted paper bag 70 is disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-238792 (Patent Document 2).

  By the way, when an article is given as a “crude product” or the like, as shown in FIG. 6 or FIG. A source display 19 such as a company name is printed. Note that the type of title display 18 (characters such as crude products, participation prizes, appreciation, and congratulations) and the source display (company name etc.) 19 are printed on the surface of the storage bag each time depending on the contents of use or the client.

JP 2000-219245 A JP 2000-238792 A

  Since the plastic film bag 50 of FIG. 6 (first conventional example) is excellent in flexibility, when the article (folding towel 9) is stored in the bag, the thickness of the article (folding towel) 9 is as follows. Even if it is thick (for example, a thickness of 25 to 35 mm), the lower end 9a of the article 9 can relatively easily spread the bottom of the bag, so that the lower end 9a of the article is considerably close to the bottom 51 of the plastic film bag 50. Stored to a near depth.

  However, since the plastic film bag 50 cannot be incinerated at the time of disposal, it must be separated and disposed as landfill waste, which requires time and effort and is not good for the environment. Further, in the plastic film bag 50, it is difficult to print directly on the bag surface in the bag state (printing of the decorative display 16, 17, the title display 18, the source display 19, etc.). Is stored in the plastic film bag 50 together with the folding towel 9, but in this case, there is a problem that the foldable paper 52 is separately required and a process of wrapping the folded towel 9 with the foldable paper 52 is necessary. .

  The paper bag 60 shown in FIGS. 7 to 10 (second conventional example) is paper, so that it can be incinerated at the time of disposal and printed easily in the bag state (for example, requested title display 18, source display). 19 etc.).

  However, in the paper bag 60 of the second conventional example, since a paper material having a considerable thickness is used in terms of bag breaking strength, the bottom cover material 61 is folded and attached to the bottom of the bag. The bottom 60a (particularly both corners 62, 62) of the paper bag 60 is less likely to swell. When the stored article is bulky (thick) like the folded towel 9, when the article (folded towel) 9 is stored in the paper bag 60, the bag body is inflated relatively easily. However, since both corners 62 and 62 (FIG. 9) of the bottom 60a cannot be expanded, the lower end 9a of the storage article 9 is considerably separated from the bag bottom 60a as shown in FIGS. It can only be inserted to the position (shallow position). That is, as indicated by the symbol L in FIGS. 9 and 10, the residual depth from the lower end 9a of the article to the inner bottom 60a of the bag is about 25 to 30 mm, and the surplus space S (FIG. 10) is increased. There was a problem that the surplus space S portion was jerky.

  Moreover, when the bulky folded towel 9 is stored in the paper bag 60, the opening 63 is pushed out into an oval shape (or an oval shape), but the left and right side edge lower ends 64a and 64a of the lid piece 64 are the bags. When the left and right outer ends of the opening width are continuous at the same position, the left and right side edges of the lid piece 64 are also curved. At that time, when an unnatural action works on the left and right side edge lower ends 64a and 64a of the lid piece 64, the side edge lower ends 64a and 64a are easily broken, and the left and right side edges of the lid piece 64 are curved. There is also a problem that the lid piece 64 is difficult to bend when the lid piece 64 is folded back.

  Further, in the above-described gusseted paper bag 70 of FIG. 11 (third conventional example), each gusset portion 71, 71, 72 is easily spread when the article (folding towel) 9 is stored, so that the lower end of the article Since it is fully inserted and made of paper, it can be printed in the form of a bag and incinerated at the time of disposal (does not need to be disposed of separately).

  However, this type of gusseted paper bag 70 has an extremely high manufacturing cost as compared to a flat envelope-shaped paper bag (the one shown in FIGS. 7 to 8), and is used for this type of “crude product”. Not suitable for storage bags.

  Therefore, in view of the problems of the respective storage bags, the present invention easily inserts the lower end portion of the stored article (folded towel) to the vicinity of the inner bottom of the bag even in the case of a paper flat envelope storage bag. It is intended to be able to be stored in an open state.

  The present invention has the following configuration as means for solving the above problems.

Invention of Claim 1 The invention of claim 1 of the present application is directed to a vertically long rectangular storage bag for storing a bulky article such as a folded towel. When a towel is used as a stored item, the towel is folded several times in the length direction and width direction (folded to a total of about 12 to 16 folds), and the size of the folded towel is a vertically long face towel. Is 23 to 24 cm, the width is 11 to 12 cm, and the thickness is about 25 to 35 mm. In addition, the storage bag of this application can employ | adopt an appropriate | suitable article | item as long as it has a moderate thickness in addition to the said folding towel as a storage article.

  The storage bag according to claim 1 is a paper-made flat envelope-shaped bag body formed with saddle-shaped notches that extend across the side and bottom sides of the bag body by a predetermined small width. It is characterized by that.

  The bag body portion of the storage bag has a flat envelope shape and is formed to have a size (for example, a vertical length of about 24 to 25 cm and a horizontal width of about 14 to 15 cm) that can store the folded towel with almost no excess. Further, since the storage bag is made of paper, a paper material having a thickness that can ensure the bag breaking strength is used. A lid piece for closing the opening is integrally formed on the upper portion of the bag body, and a bottom lid material is folded and adhered to the bottom portion.

  The notch at each corner of the bottom of the bag body is notched in a bowl shape in the range of about 6 to 10 mm (preferably about 8 mm) in the width direction and the height direction. In this way, when the hook-shaped notches are formed at both corners of the bag bottom, the side edges and the bottom edge of the bag body function as gussets.

  And when the bowl-shaped notch is formed in each corner of the bag bottom as described above, each corner of the bottom of the bag body is stored when the article (folded towel) is stored in the storage bag. Can be inflated almost without resistance. In addition, although there is no room for swelling at a normal corner portion having no notch at the bottom, it can be easily inflated if a notch is formed at the corner as in the present application.

Invention of Claim 2 of the Invention The invention of claim 2 of the present application is the storage bag of claim 1, wherein the storage bag has a lid piece for closing the opening of the bag body, and the left and right side edges of the base part of the lid piece are covered with the bag. It is characterized in that it is moved inward by a predetermined small width from the left and right side edges of the main body.

  That is, the left and right side edges of the base part of the lid piece are cut out by a predetermined small width (for example, about 6 to 10 mm, preferably about 8 mm), so that the width of the base part of the lid piece is slightly smaller than the opening width of the bag body.

  Thus, when the width of the base portion of the lid piece is reduced, the width of the base portion of the lid piece is short even if the opening swells into an oval shape (or an oval shape) when the article (folding towel) is stored in the bag. Therefore, there is no bending allowance, and the entire lid piece maintains a flat state.

  Each of the storage bags according to claims 1 and 2 of the present application can store a folded bag such as a Japanese towel that is relatively thin. In that case, the bag body does not swell so much.

Advantages of the Invention of Claim 1 In the storage bag according to claim 1, since the hook-shaped notches are formed at the corners of the bag bottom, the side edges and the bottom edge of the bag body are respectively mated. To function as a part. Therefore, even if the bag body is made of paper and formed into a flat envelope shape, when the article (folding towel) is stored in the storage bag, each corner near the bottom of the bag body is easily inflated. There is an effect that the lower end of the stored article (folding towel) can be easily inserted to the vicinity of the bottom in the bag. In this way, when the lower end portion of the stored article is inserted to the vicinity of the bottom portion in the bag, the excess space in the inner bottom portion of the bag is reduced, and the storage state is improved.

Advantages of the Invention of Claim 2 In the invention of claim 2 of the present application, in the storage bag of claim 1, the left and right side edges of the lid base portion are moved inward by a predetermined small width from the left and right side edges of the bag body. As a result, when the article (folding towel) is stored in the bag, the left and right sides of the lid piece are maintained in a flat state even if the opening swells into an oval shape (or an oval shape). Become.

  Therefore, in the storage bag of claim 2, in addition to the effect of claim 1, the left and right side portions of the base portion of the lid piece are not easily broken when the article is stored, and there is no problem when the lid piece is folded back and covered. There is an effect that it can be bent.

  Each of the storage bags according to claims 1 and 2 of the present application is made of paper, so that it is easy to print and can be incinerated at the time of disposal, so that no separate disposal is required as in the case of plastic film. Due to the shape, the manufacturing cost is low.

  Hereinafter, the storage bag of the present embodiment will be described with reference to FIGS. In addition, in this Example, although the folding towel 9 which folded the face towel is employ | adopted as a storage article, this folding towel 9 is 23-24 cm in length in a folded state (total 12-16 folding state). The width is about 11 to 12 cm and the thickness is about 25 to 35 mm.

  As shown in FIGS. 1 and 2, the storage bag of this embodiment is made of paper and is formed in a vertically long rectangular flat envelope shape. Since the storage bag is made of paper, a paper material having an appropriate thickness is used in terms of bag breaking strength.

  The size of the portion of the bag body 1 is such that the folding towel 9 can be accommodated almost without deficiency, and is formed, for example, in a length of about 24 to 25 cm and a width of about 14 to 15 cm.

  The storage bag of this embodiment is used to store the folding towel 9 for “crude”, and as shown in FIG. 1, decorative display such as funnel decoration 16 and water draw 17 on the surface of the storage bag, “ The title characters 18 such as “crude” and the origin indication 19 such as the company name are printed. In addition, decorative displays such as the candy decoration 16 and the water draw 17 (in this embodiment, one strip-shaped red line) are pre-printed on the surface of the storage bag as a common display, but the type of the title display 18 (crude, participation) Letters such as awards, appreciation, and congratulations) and a source display (company name, etc.) 19 are printed on the surface of the storage bag each time depending on the contents of use or the client.

The corners 5 and 5 of the bottom 4 of the bag body 1 are respectively provided with saddle-shaped notches 6 and 6 straddling the side portions 1a and 1b of the bag body 1 by a predetermined small width (H, W ₁ ). Is formed. The size of each cutout portion 6, 6 is a vertical length H and the width W ₁ of about 8mm, respectively.

Further, the lid member 3 for closing the opening 2 of the bag body 1, the right and left side edges 3b of the base portion 3a, 3b of the bag body 1 of the right and left side edges 1a, inner respectively predetermined small width W ₁ than 1a It is formed in the state brought close to. That is, the left and right side edges 3b and 3b of the base portion 3a of the lid piece 3 are each cut out by a predetermined small width W ₁ (about 8 mm like the notch portion 6 at the bottom) (notch portions 7 and 7), and the lid piece root portion 3a. Is slightly smaller than the opening width of the bag body 1.

  As shown in the developed view of FIG. 3, the storage bag has a front surface portion 11, a back surface portion 12 (continuous in a halved state on the left and right of the surface portion 11), an upper lid portion 13, and a bottom lid portion 14. Cutout portions 6 and 6 are formed at the left and right end portions of the bottom portion 4, respectively, and the cutout portions 7 and 7 are formed at the left and right side edges 3 b and 3 b of the base portion 3 a of the upper lid portion 13, respectively. And it folds in each dotted-line part of FIG. 3, and while sticking the side edges of each back surface part 12 and 12, the bottom cover part 14 is stuck to the lower end part of the back surface part 12, and it forms in a flat envelope shape. ing. In addition, a funnel decoration 16, a waterbrush 17 and the like are printed in advance on the outer surface of the front surface portion 11 and the rear surface portions 12 and 12.

The storage bag of this embodiment has the following characteristics. First, the bottom portion 4 of the bag body 1 has a relatively strong rigidity because the bottom lid member 14 is folded and attached as shown in FIG. Since the bowl-shaped notches 6 and 6 are formed, the side edges 1a and 1a and the bottom edge 1b of the bag body 1 each function as a gusset. That is, the opposite side edge portions 1a of the bag body 1, with 1a is gusseted portion of the folded outer each one by a width W _1, the gusseted portion of the folded outer only the bottom edge 1b the height H of the bag body 1. In addition, before the folding towel 9 is stored, the lateral width W remains wide (W = 14 to 15 cm) with the bag body 1 being thin (in a state of a flat envelope).

4 and 5, when the folding towel 9 is stored in the bag body 1 from the opening 2, the front and back surfaces of the body portion of the bag body 1 are pushed outward, and at that time side portions (the gusset portions) 1a, the width W ₀ is small of the bag body 1 is inflated 1a is over the entire length (W ₀ is about 10~15mm smaller than the original width W). Moreover, the bottom part 4 can swell the bottom part (becomes a gusset part) 1b without much resistance by pushing the lower end part 9a of the folding towel 9 deeply, and the lower end of the folding towel 9 is shown in FIG. The portion 9a can be inserted to a position close to the inner bottom portion of the bag. This can be achieved by forming the notches 6 and 6 in the corners 5 and 5 of the bottom 4 respectively. In the article storage state, the notches 6 and 6 at the bottom corners are small as shown in FIG. 4, and the stored items 9 inside the notches 6 and 6 are difficult to see.

  When the folded towel 9 is stored, the opening 2 of the bag body 1 also swells in an oval shape (or an oval shape). At that time, the left and right side edges 3b and 3b of the base 3a of the lid piece 3 are inward in advance. Since it is close (forms the notches 7, 7), there is no room for bending at the side edges 3 b, 3 b of the lid piece 3. Accordingly, even when the folded towel 9 is stored, the entire lid piece 3 maintains a flat state.

  Thus, in the storage bag of this embodiment, even if it is made of paper and has a flat envelope shape, the article (folding towel) 9 is easily inserted into a position where the lower end portion is close to the inner bottom portion of the bag. As a result, the excess space at the inner bottom of the bag is reduced and the storage state is improved. Further, since the entire lid piece 3 is maintained in a flat state in the article storage state, the left and right side portions 3b and 3b of the lid piece root portion 3a are not easily torn and the lid piece 3 is folded back to be covered. Can be bent without any problem.

  Since the storage bag of this embodiment is made of paper, it is easy to print, can be incinerated at the time of disposal, and has a flat envelope shape, so that the manufacturing cost is low.
