Description

  The present invention relates to an improvement of a paper handbag.

  2. Description of the Related Art Conventionally, paper handbags have been widely used as a convenient container that is frequently used when a user finds a favorite product on the go, purchases it, and takes it home. The handbag is made of a thin paper member 1 and is formed into a box shape through folds so that it can be conveniently stored in a narrow space when not in use. Hand straps 8 and 8 are attached to the upper portions of the front portion and the back portion, which are both sides of the opening portion 7 provided on the upper portion of the bag body 6 formed so as to be folded with the bottom portion 5 so that it is convenient to carry. It is formed.

  To attach both ends of the hand straps 8 and 8 to both sides of the opening 7 located at the top of the bag body 6, the upper peripheral edge of the bag body 6 is shown in FIG. The folded piece 9 existing in the part is folded back to the inner surface of the opening to form a double layer, or the elongated reinforcing plates 10 and 10 are arranged inside the folded piece to form a triple layer. And the edge part of the hand straps 8 and 8 was inserted from the outer side into the insertion holes 11 and 11 formed in the upper part of the front part 2 and the back part 3 on both sides of the opening part of the bag body, and was positioned inside the opening part 7. Knots 12 and 12 are provided at the end portions and latched (see, for example, Patent Document 1).

  The knots 12, 12 provided at the ends of the hand straps 8, 8 require an operation of making a knot by manual work after being inserted into the insertion holes 11, 11 formed on both sides of the opening of the bag body 6, Mechanization was difficult. And since the knots 12 and 12 located on the inner surface of the opening 7 of the bag body 6 are formed large so as not to come out of the insertion hole, the knots are obstructive when the product is taken in and out of the bag body. Had the disadvantages.

  As an example of mechanizing the manufacture of the handbag, the existing hand portion 15 shown in FIG. 5 is used. This handle portion 15 is made of a wire such as an adhesive or a stapler on a reinforcing plate 17 such as a cardboard which is formed in a narrow and long shape at both ends of a strap 16 in which a flexible string material such as a braid is bent in an inverted U shape. It is fixed using. The reinforcing plate 17 of the handle portion is provided, for example, with a folding piece 9a on the upper peripheral edge of the bag body 6 shown in FIG. 7 via a folding line 19, and slightly below the folding line 19 (the paper body is unfolded). In the state, the reinforcing plate 17 of the handle 15 is bonded and fixed mechanically or manually to the inner surface of the bag body 6 located in the upper part (the state in which the folded piece is not yet folded). Further, the folded piece 9a is also folded and fixed to the inside of the opening 7 from the folding line by mechanical or manual work.

  Pull the strap 16 outward from the upper side of the substantially J-shaped cuts 20 and 20 provided in pairs in the middle portion of the folded piece 9a located above the front and back portions of the handbag, Pulled out from the inside of the folded piece 9a into the opening, the substantially J-shaped cuts 20 and 20 are provided to communicate with the lower end of the folded piece, and the substantially J-shaped cuts 20 and 20 are provided on the inner surface of the opening of the bag body. The insertion hole is not provided (for example, refer to Patent Document 2).

  However, a narrow space L may exist between the folding line 19 of the bag body and the upper portion of the reinforcing plate 17 of the handle portion 15, and there is a drawback that the paper material 1 is easily cut. Moreover, the reinforcing plate 17 is bonded and fixed from both sides by the bag body 6 and the folded piece 9a. However, since the folding line 19 and the upper part of the reinforcing plate 17 are separated from each other, the folding lines 9a and 9a are folded. Nineteen portions were not effectively used to increase the attachment strength of the handle. In addition, a substantially J-shaped curved pattern is generated on the folded piece on the inner surface of the opening. That is, a special pattern including not only a straight line in the vertical direction but also a horizontal line portion is conspicuous, and there is a disadvantage that it is difficult to obtain a high-class feeling.

  Further, in addition to the use of the handle 15 shown in FIG. 5, the embodiment will be described with reference to FIG. 8. The folded piece 9b provided on the upper peripheral edge of the bag body 6 is folded inside the opening of the bag body. A cut groove 21 having an interval length M between the straps is provided in the folding line 19a for the purpose, and the reinforcing plate 17 disposed inside the folded piece 9b is connected to the inner surface of the bag body 6 and the folded piece 9b. An inverted U-shaped strap 16 that is bonded to the inner surface and has both ends attached to the reinforcing plate 17 is formed to be drawn out of the cut groove 21, that is, outside the folding line 19 a. After pulling out the strap 16 there, it is necessary to close the cut by closely attaching the cut groove 21 with an adhesive (for example, see Patent Document 3).

However, since the cut grooves 21 on the folding line 19a other than the strap 16 located on both sides in the interval length M of the two reverse U-shaped straps 16 are cut open, they can be bonded to each other using an adhesive. Although it is closely closed, the closed cut groove 21 remains as a linear pattern or a linear trace. Since the folding line 19 is located at the upper end of the opening and is the most conspicuous place, there is a problem that the aesthetics of the bag body is deteriorated and a high-class feeling cannot be obtained.
Japanese Patent Application Laid-Open No. 2005-80705, FIGS. Japanese Patent Laid-Open No. 10-23916, FIG. Japanese Utility Model Publication No. 02-129046, FIG.

  In view of the above problems, the present invention provides a T-shaped notch on the folded piece at the upper peripheral edge of the bag body so that the strap can be inserted, and the strap is inserted on both sides of the opening of the bag body. The attachment of the strap is simplified by making it possible to attach the strap without needing to make a hole in the strap, and the strap attachment portion is strengthened, and a high-quality handbag is obtained without deteriorating the aesthetics. With the goal.

In order to solve the above-mentioned problems, the present invention is a paper handbag, and has a handle 15 attached to both ends of a strap 16 that is bent in an inverted U-shape and attached to a reinforcing plate 17. A bag body in which a folding line 19 is provided on the upper peripheral edge, and a T-shaped cut 23 is formed on each of the folding piece 9 and the folding line 19 located on both sides of the rectangular bag body 6 having the folding piece 9 on the upper peripheral part. 6, the handle 16 is disposed on the inner surface of the upper portion of the bag body 6, and the strap 16 having an inverted U shape is hooked in the T-shaped notch 23. The piece is folded back and adhered and fixed to the inner surface of the opening 7, and the strap 16 is pulled out from the transverse cut 23a of the T-shaped cut.
Pull out the reverse U-shaped strap from the lateral cut provided in the folding line located at the upper end of the opening of the bag body, and make any cut in the folding line other than the horizontal cut. In addition, the folded piece bonded to the inner surface of the opening only has a vertical line pattern, so that a high-class feeling can be obtained.

The T-shaped cut 23 is composed of a horizontal cut 23 a and a vertical cut 23 b having a width S of the strap 16, and the horizontal cut 23 a is paired on the folding line 19. The vertical cut 23b is formed continuously from the middle part of the horizontal cut to the end of the folded piece 9 in the vertical direction.
As described above, the T-shaped notch for allowing the strap to pass through the folded piece is a simple shape combining straight lines, so the strap can move smoothly in the T-shaped notch, Since the incision is constituted by a straight line, even if the incision groove is bonded to close the incision groove, it merely becomes a linear pattern and does not become a noticeable scar.

On the folding line 19 provided horizontally at the upper peripheral edge of the bag body 6, a pair of horizontal cuts 23 a having a length equal to the horizontal width length S obtained by crushing the strap 15 are formed. The reinforcing plate 17 of the handle portion is adhered and fixed to the lower inner surface of the folding line 19 so that the upper part is in close contact with the folding line 19 that turns the folding piece 9 inward of the opening 7, and the T-shaped notch The vertical cuts 23b are bonded to each other.
Since the reinforcing plate 17 of the handle portion that is arranged and bonded inside the folded piece is matched with the folding curve 19 provided at the base of the folded piece, it is adhered to the inner surface of the bag body and the inner surface of the folded piece. Thus, the opening is reinforced, and the upper portion of the reinforcing plate 17 is bonded to the inside of the folding line 19 so that the weight of the product accommodated in the bag body is reinforced at the folding line 19 portion. Therefore, it is possible to provide a handbag in which the attachment portion of the strap 16 is further strengthened.

  Since the present invention is configured so that the strap is pulled out from the folding line portion provided at the upper end of the opening of the bag body, it is not necessary to provide insertion holes on both sides of the opening for inserting the strap. The notch that passes through is a T-shaped notch that is a simple shape and is a combination of straight lines, so it is easy for the strap to move through the vertical notch, and the notch is straight Therefore, there is an advantage that it is bonded to form a simple straight line pattern and does not deteriorate the sense of quality.

  FIG. 1 is a perspective view in which a paper handbag according to the present invention is partially omitted, and FIG. 2 is an enlarged perspective view of an essential part of an inner surface of an opening portion in which the hand is attached to the bag body. 3 is a developed view in which a part of the paper member constituting the bag body is omitted, FIG. 4 is an enlarged cross-sectional view of the main part in which the upper part of the paper member showing the T-shaped incision is developed, and FIG. FIG. 1 is a normal paper member, and the front portion 2 and the back surface portion 3 are integrally formed continuously through folds and both side surface portions 4 and 4, respectively, and one side end of the paper member 1, for example, the front portion 2 is bonded to the other end of the paper member, for example, the inner surface of one side surface portion 4, and has a bottom surface portion 5 to form a rectangular foldable bag. A main body 6 is formed, and this structure is the same as a conventional paper handbag.

  A folding piece 9 is provided above the folding line 19 provided in the horizontal direction on the upper peripheral edge portion of the bag body 6, and the reinforcing plate 17 of the handle portion 15 shown in FIG. The folded piece 9 wraps a reinforcing plate 17 inside, and is bonded and fixed to the reinforcing plate 17 and the inner surface of the bag body 6, and an opening 7 is provided in the upper part of the bag body. The folded pieces located above the front part 2 and the back part 3 of the paper member 1 are each formed with a pair of T-shaped cuts 23 as shown in FIGS.

  The T-shaped cut 23 is formed by turning a folded piece 9 provided at the upper peripheral edge of the bag body inward of the opening, and is positioned on a folding line 19 provided at the upper end of the opening to make a pair. A notch 23 is formed and communicated from the middle part of the lateral notch 23a to the end of the folded piece 9 (upper end in FIGS. 3 and 4), and a vertical notch 23b is integrally provided in the vertical direction to form a T-shape. Is formed. Therefore, in FIG. 4, the strap 16 is moved in the vertical cut 23b provided in the folded piece 9 positioned above the front portion and the back portion and folded back, and the strap 16 is moved in the horizontal cut 23a. The strap is in a state of passing through the folded piece 19.

  The lateral width S of the lateral cut 23a provided on the folding line 19 is equal to the lateral length in a state in which the strap 16 deformable by a flexible member is crushed by the bag body 6 and the inner surface of the folded piece 9. It is formed in length. Of course, the strap 16 can also be used by a strap made of a hard synthetic resin having flexibility. Further, the length of the folded piece 9 in the vertical direction is made longer than the length of the reinforcing plate 17 in the vertical direction so as to wrap the reinforcing plate 17 and finish the inner surface of the opening beautifully.

  In order to attach the handle 15 to both sides of the opening of the bag body 6, the inner surface of the front part 2 and the rear part 3 of the developed paper member 1 shown in FIG. The reinforcing plates 17 and 17 of the hand portion 15 are bonded to each other with an adhesive by mechanical or manual work. Subsequently, each fold of the bag body is folded and a narrow adhesive piece 13 provided at one end is adhered and fixed to the side surface portion 4 at the other end, forming a bottom surface portion and opening 7 at the upper side. The bag body 6 is formed in a rectangular box having a bottom, but the bottom surface portion may be formed last. The folded piece 9 is folded inward of the opening 7 by mechanical or manual work, and adhered to the inner surface of the bag body to reinforce the opening.

  A vertical cut 23b of the T-shaped cut 23 provided in a pair with the folded piece 9 positioned above the front and back portions is provided continuously with the horizontal cut 23a. For this reason, no insertion holes are provided in the front and back portions of the bag body, and the strap 16 located inside the folded piece 9 can be pulled out to the outside of the folded piece, that is, into the opening. 16 is passed from the inside of the folding piece 9 through the vertical cut 23b provided in the vertical direction, and is hooked into the horizontal cut 23a provided on the folding line 19 positioned at the upper end of the opening and pulled out outward. It has a configuration.

  Therefore, a clean and high-quality handbag can be formed, but the folded piece 19 has a linear line pattern extending in the vertical direction from the middle portion of the horizontal cut 23a, that is, from the opening portion to the lower portion of the bag body. However, the line pattern is not conspicuous because it is not in the horizontal direction but in the vertical direction, and is not conspicuous from the outside because it is located on the inner surface of the opening, so that the sense of quality is not impaired.

  After the strap 16 passes through the vertical cut 23b, the folded piece 19, particularly the vertical cut 23b is brought into close contact with the adhesive applied to the inner surface of the folded piece 19 or the surface of the reinforcing plate 17. After the straight line in the vertical direction or a straight line pattern is formed. A horizontal cut 23a provided continuously to the vertical cut 23b is located on a folding line 19 located at the upper end of the opening 7, and is provided on a reinforcing plate located inside the folded piece. The string 16 passes through the vertical cuts 23b and moves in the horizontal cuts 23a, and is pressed and thinned from the front and back by the inner surface of the front portion 2 and the inner surface of the folded piece 19, and is expanded in the left-right direction. It becomes the same length as the horizontal width length S, is hooked in the horizontal cut 23a, becomes thin and is drawn upward, and gradually becomes the original rounded state. The horizontal cuts 23a are manufactured so as not to form gaps by adhering around the straps.

  Unlike the conventional bag body, a pair of insertion holes are provided on both side surfaces of the opening 7 of the bag body, the ends of the straps are inserted through the insertion holes one by one, and the end portions of the straps This eliminates the need for manual operations such as providing knots, and does not provide knots at the ends of the straps, and since there are no knots inside the opening, there is no hindrance to taking in and out of products.

  Furthermore, the reinforcing plate 18 disposed inside the folded piece 9 does not necessarily have to be attached in contact with the folding line 19. Due to machining limitations, there is almost no problem even if there is a gap S between the upper end of the folding line 19 and the upper part of the reinforcing plate 17 disposed and bonded inside the folded piece 9. That is, the strap is pulled out from the horizontal cut 23a provided in the folding line 19 located at the upper end of the opening, and only a vertical pattern is formed on the inner surfaces on both sides of the opening. The handbag can be finished neatly.

  The strap 16 is preferably made of a flexible cloth, and the cross section of the flexible cloth string may be circular or belt-shaped. If it is formed so as to match the inside of the lateral cut 23a with S, it can be finished beautifully.
