Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a closing structure that can completely and reliably close an opening for storing things in a carry-on bag.

(Prior Art) A carrying bag usually includes a bag body having an opening for storing things at the upper end, and carrying straps are provided protruding from both opening pieces that constitute this opening and face each other. .

By the way, since the opening of the above-mentioned carrying bag remains open, there is an inconvenience that, for example, when the bag is placed horizontally on a luggage rack on a train, the contents easily roll out through the opening. Furthermore, even when the device is being held in the hand, there is a risk that someone else may inadvertently peek at the contents through the opening.

Therefore, the means for closing the opening is
Various proposals have been made in the past. These will be explained with reference to FIGS. 7 to 13.

(1) Figure 7 shows the first conventional example. In the figure, 2
Reference numeral 1 denotes a carrying bag, and this carrying bag 21 includes a square tube-shaped bag body 22 with a bottom, and the upper end of the bag body 22 forms an opening 23 for storing things. In addition, inverted U-shaped handbag straps 25 and 25' are protruded from front and rear opening pieces 24 and 24', which constitute the opening 23 and face each other in the front and rear, respectively.

Cover piece 2 from the upper end of the rear opening piece 24'
7 extends, and this cover piece 27 opens and closes the opening 23 by rotating downward. In this case, a slit 28 is formed in the middle of the cover piece 27 in the extending direction, and the front hand strap 25 is fitted into this slit 28.
Further, an adhesive means 29 is provided at the extending end of the cover piece 27. This is, for example, Magic Tape, adhesive glue or adhesive (adhesive) tape. 30 is a bending line, and after bringing the lower surface of the cover piece 27 into contact with the upper end of the opening 23, the extending end side of the cover piece 27 is bent around this bending line 30 as shown by the arrow in the figure. Moreover, if the adhesive means 29 is bonded to the front surface of the bag body 22, the opening 2
3 will be closed.

Since each of the following conventional examples has the same basic configuration as the first conventional example, the reference numerals are attached to the drawings and the explanation thereof will be omitted, and the different configurations will be explained.

(2) Figure 8 shows the second conventional example, in which the front and rear opening pieces 2
4 and 24' are joined to each other by a zipper 32 and can be opened, and the opening 23 is closed by this joining. 33 is an adhesive piece, each handbag string 25,
Each lower end of 25' is adhered to the bag body 22 by this adhesive piece 33.

(3) Figure 9 shows the third conventional example, in which the rear opening piece 2
Adhesive means 29 is attached to the inner surface of 4', and when the front and rear opening pieces 24, 24' are overlapped, they are bonded and the opening 23 is closed.

(4) FIG. 10 shows a fourth conventional example, in which adhesive means 29 is attached to adhesive piece 33. The other configurations are the same as the third conventional example.

(5) FIGS. 11 to 13 show the fifth conventional example. Arc-shaped slits 34, 34' are formed at the upper end of each opening piece 24, 24', and these slits 34, 34'
4, 24' and the adhesive piece 33.

When carrying this carrier bag 21 by hand, the first
2 and 13, the front hand strap 25 is inserted through the rear slit 34', the rear hand strap 25' is inserted through the front slit 34, and both hand straps 25, 25' are inserted.
Grip it integrally. In this way, both hand straps 25, 25' press the upper ends of both opening pieces 24, 24' to join each other, and the opening 23
is closed.

(Problems to be solved by the invention) However, each of the above conventional configurations has the following disadvantages. That is, (1) According to the first and second conventional examples, separate members such as the cover piece 27 and the zipper 32 are provided to close the opening 23, and therefore the structure is complicated. In addition, such a carrying bag 21
When manufacturing a bag, a device for attaching the cover piece 27 and zipper 32 as described above is added to the conventional manufacturing machine that manufactures the carrier bag 21 consisting of the bag body 22 and the carrier strings 25, 25'. If this were to be done, the manufacturing machine would need to be significantly modified, resulting in an inconvenience that the cost of manufacturing the carrier bag 21 would be high.

(2) In addition, in the case of the third and fourth conventional examples, even if the opening 23 can be closed in the part where the adhesive means 29 is provided, other parts cannot be closed sufficiently. It's inconvenient. Therefore, it is conceivable to provide the adhesive means 29 over the entire opening 23, but in this way, once the opening 23 has been closed, when it is opened again to take things in and out, the operation will be difficult. It becomes extremely complicated.

(3) Furthermore, in the case of the fifth conventional example, the above third and fourth
As with the conventional example, there is a disadvantage that the opening 23 cannot be completely closed.

(Purpose of the invention) This invention was made with attention to the above-mentioned circumstances, and it is possible to completely close the opening of a carrier bag with a simple structure, and it is possible to make such a carrier bag inexpensive. The aim is to make it possible to manufacture

(Structure of the device) The feature of this device for achieving the above object is that it includes a bag body having an opening for storing things at the upper end, and one of the two opening pieces forming the opening and facing each other. In a carrying bag in which a carrying strap is provided on one of the opening pieces from a position lower than its upper end, a perforation extending downward from the upper end of the other opening piece is made to correspond to the carrying strap. When the upper ends of both opening pieces are overlapped and folded integrally toward one side of the opening, the slit formed by breaking the perforation fits into the base of the handbag string. It's on point.

(Function) When trying to close the opening 3 of the carrying bag 1 by overlapping the upper ends of both opening pieces 5a and 5a' and folding them together, the perforation 11 of the opening piece 5a is broken and formed. Slits 11
a fits into the base of the handbag string 9'. For this reason,
Both opening pieces 5 to be bent as above
a, 5a' and the handbag strings 9, 9' do not interfere with each other. Therefore, both opening pieces 5a, 5a' can be bent over their entire width direction to close the opening 3.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In FIGS. 1 and 2, 1 is a carrying bag, and this carrying bag 1 includes a square tube-shaped bag body 2 with a bottom.
The upper end of this bag body 2 serves as an opening 3 for storing things. The bag body 2 is composed of front and rear main bag pieces 5, 5' facing each other, side bag pieces 6, 6' facing left and right, and a bottom bag piece 7, which are made of paper, resin film, or other materials. They are integrally formed by overlapping each other.

The upper parts of each of the main bag pieces 5, 5' are front and rear opening pieces 5a, 5a' that constitute the opening 23, and the inner surfaces of these opening pieces 5a, 5a' have an inverted U-shaped handbag. Strings 9, 9' are provided protrudingly. in this case,
The lower end of each of these handbag straps 9, 9' on the base side is firmly adhered to the inner surface of each opening piece 5a, 5a' by an adhesive piece 10. It is located a certain distance below the top of '.

The above-mentioned two-hand straps 9 and 9' are of the same shape and size,
They are placed facing each other in the front and back. Also, corresponding to the base of each handbag string 9, 9', each opening piece 5a,
Perforations 11,1 extending downward from the upper end of 5a'
1' are formed, and each perforation 11,
The lower end of the adhesive piece 11' is located near the upper end of the adhesive piece 10 and extends to form an inverted T-shape. in this case,
Each perforation 11, 11' is formed by discontinuously arranging minute cuts or through holes, and any method of forming the perforation may be used as long as it can be easily broken.

In addition, 12 is a folding line, and this portion is folded when the carrying bag 1 is folded flat.

3 and 4, the carrying bag 1 is further constructed as follows in order to enable the opening 3 to be closed. That is, Figures 3 and 4
As shown by the arrow A and the solid line in the figure, both opening pieces 5
When the upper ends of a and 5a' are overlapped and folded integrally and over the entire width direction toward the rear opening piece 5a' side (rearward), the perforation of the front opening piece 5a A slit 11a formed by breaking 11 is adapted to fit into the base of the rear strap 9'.

Then, as shown by the arrow B and the imaginary line in FIGS. 3 and 4, if the upper ends of both opening pieces 5a and 5a' are further folded back downwards, as shown in FIG. The opening 3 is completely closed.

In the above case, since the distance between the opposing edges of the slit 11a is narrow, the opposing edges of the slit 11a pinch the base of the rear hand strap 9' due to the elasticity of the opening piece 5a. Also, since both opposing edges of this slit 11a are formed by breaking the perforation 11 and have many minute irregularities, the state in which the slit 11a pinches the rear hand strap 9' is relatively difficult. firmly held,
That is, the closed state of the opening 3 is reliably maintained.

In addition, when closing the opening 3 by bending both opening pieces 5a and 5a' backward as described above,
The perforation 11' of the rear opening piece 5a' may not be provided. Moreover, contrary to the above, both opening pieces 5a, 5
When folding a' forward to close the opening 3, do the same as above at the perforation 1 of the rear opening piece 5a'.
The slit formed by breaking 1' fits into the base of the front hand strap 9, and at this time,
The perforations 11 in the front opening piece 5a may not be provided. In addition, in the above embodiment, each perforation 11, 1
Although 1' is shown as having one strip, it may be two strips that are close to each other and substantially parallel to each other.

Furthermore, in order to more securely close the opening 3, adhesive means as shown in the conventional example is provided between the opposing surfaces of the bent opening pieces 5a, 5a' and the main bag pieces 5, 5'. may be provided in advance, or the bent opening pieces 5a, 5a' may be adhered to the main bag pieces 5, 5' with separate adhesive tape or the like.

FIG. 6 shows another embodiment.

In this embodiment, both hand straps 9 and 9' are provided protruding from the outer surfaces of the opening pieces 5a and 5a'. In this case, when both opening pieces 5a, 5a' are bent in the direction of arrow A in the figure, both perforations 11, 11'
Both slits 11a, which are formed by breaking the slits, sandwich the base of the rear carry strap 9' so that the two slits fit together.

Other configurations and functions are the same as those in the previous embodiment, but
According to this configuration, since the two slits 11a sandwich one of the handbag straps 9, 9', the opening 3 can be maintained in a closed state more reliably.

(Effect of the invention) According to this invention, the upper ends of both opening pieces can be folded over the entire width direction when they are overlapped, so the opening of the handbag can be folded over the entire width of the opening pieces. will be closed. Therefore, it is possible to reliably prevent the contents from accidentally rolling out or being viewed by a third party. In particular, when the slits formed by breaking the perforations when both opening pieces are bent are fitted with the handbag string, if the slits are made to sandwich the handbag string, the closed state of the opening will be better. Reliably held.

In addition, since this invention simply forms perforations on the opening piece to correspond to the carrying strap, firstly, the above effect can be obtained without increasing the number of parts, i.e., with a simple structure, which is extremely useful. Secondly, when manufacturing this carrier bag, it is sufficient to simply add a device for forming perforations to a conventional manufacturing machine that manufactures carrier bags consisting of a bag body and a carrying strap, so that the conventional manufacturing machine can be easily repurposed, and therefore the carrier bag of this invention can be manufactured inexpensively.
