Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an openable / closable slide fastener provided at an opening of a bag made of a synthetic resin sheet used as a package for foodstuffs or the like.

[0002]

2. Description of the Related Art In recent years, in a synthetic resin sheet bag used as a package for foodstuffs, etc., after opening the bag,
There is an increasing number of devices provided with a slide fastener so that the opening can be opened and closed many times without losing hermeticity.

In the slide fastener, a ridge member and a groove member which can be fitted to each other are provided on two synthetic resin sheet members constituting an opening of a bag body, and these ridges and grooves are formed. The opening is opened and closed by engaging and disengaging. Here, a method of fitting and releasing the convex and concave grooves only with fingers and a method of fitting and releasing the convex and concave grooves by an opening / closing member that slides along the opening. There are things.

[0004] By providing a slide fastener on a package bag of food or the like, the opening can be opened and closed many times while maintaining the sealing property even after the bag is opened, so that the food or the like in the package bag is stored. It is possible to prevent deterioration due to moisture absorption in the air, and the opening / closing operation itself is easy.

[0005]

In the case of a conventional slide fastener provided in a package bag, it is inconvenient to remove a stored item unless the fastener portion is separated and an opening is opened, which is inconvenient. Closing the fastener after the installation is troublesome.

Further, in the case of the conventional slide fastener, when the package bag is tilted obliquely to take out the powdery material or granular material as the storage material, the storage material is located near the ridge member and the groove member constituting the fastener. It may not be able to be taken out smoothly due to easy adhesion.

Furthermore, in this case, a part of the stored material often remains adhered to the ridge member and the groove member, and the fasteners cannot be completely closed due to the remaining adhered material, thus deteriorating the sealing performance. Sometimes. In particular, when the stored material is a fine powder or a granular material, it is likely to adhere to and remain on the ridge member and the groove member, so that the sealing property is significantly reduced.

An object of the present invention is to provide a slide fastener which can smoothly remove stored items without opening an opening of a bag or the like and does not cause a reduction in sealing performance. is there.

[0009]

In order to solve the above-mentioned problems, a slide fastener of the present invention is a slide fastener for opening and closing edges of a plurality of sheet materials,
An openable / closable fastener provided along the peripheral portion, and an open / close member slidably provided along the fastener while simultaneously opening and closing the fastener in close proximity. Wherein a through hole communicating with a gap formed between the sheet materials is formed.

[0010] With this configuration, the substance stored between the sheet members can be taken out through the through hole of the opening / closing member, so that it is possible to smoothly take out the stored material without opening the opening. In addition, since the stored item does not come into contact with the fastener portion, the deterioration of the sealing performance due to the attached of the stored item does not occur.

Therefore, for example, if the slide fastener of the present invention is used in a bag body having an interior partitioned into a plurality of spaces and having an opening formed in a direction transverse to these spaces, the bag has through holes. Because the opening and closing member has a structure that can slide along the fastener provided in the opening,
It is possible to selectively take out stored items in each space without opening the fastener portion.

Further, by providing an opening / closing means for opening / closing the through-hole formed in the opening / closing member, it is possible to ensure the sealing performance, so that the stored material leaks from the through-hole or foreign matter from the outside. It is possible to prevent intrusion of moisture and moisture.

In this case, by providing a detachable opening / closing lid in the through-hole as the opening / closing means, it is possible to effectively prevent leakage of stored items, intrusion of foreign matter or moisture, and the opening / closing operation itself. It will be easier.

[0014] Further, a structure in which a fastener portion which can be opened and closed is provided in a through hole of the opening and closing member can be provided. By adopting such a structure, the through hole itself can be easily opened and closed, so that the operability is improved and it is convenient.
The sealing performance in the closed state is improved.

Here, it is possible to provide a structure in which a plurality of fasteners are provided along the opening and the opening / closing member is slidable along the plurality of fasteners. With such a structure, the opening is closed by the plurality of fasteners, and the closing force is improved. Therefore, even if a strong force acting to separate the fasteners is applied, the opening does not arbitrarily open.

Further, by providing the opening / closing member with a measuring means for measuring the granular material or the fluid, the amount of the stored granular material or the fluid can be accurately measured when the powdered material or the fluid is taken out through the through hole of the opening / closing member. To be able to
The workability when taking out a fixed amount is improved.

In this case, the weighing means includes an opening / closing member,
It is possible to adopt a structure in which a measuring unit capable of storing a certain amount of powder or granules is provided. By adopting such a structure, the powder or the granular material or the fluid of the exact amount can be obtained by simply performing the simple operation of once storing the granular material or the fluid as the storage material in the measuring section and then discharging through the through hole. Can be taken out.

In the slide fastener 50 according to the present embodiment, a measuring portion 54 capable of accommodating a certain amount of the granular material 53 is provided below the opening / closing member 51. The measuring section 54 has the through hole 5
5 and continuously. The structure and functions of the other parts are the same as those of the slide fastener 10 of the first embodiment.

In the case of the slide fastener 50, the measuring section 54
Is provided, when removing the granular material 53 stored in the bag body 52 through the through hole 55 of the opening / closing member 51,
An aliquot can be accurately taken out.

Here, how to use the slide fastener 50 will be described with reference to FIG. First, as shown in FIG. 6A, the bag 52 is inverted so that the opening / closing member 51 faces downward, and the powder 53 in the bag 52 is stored in the measuring section 54. Then, as shown in FIG. 6B, the bag body 52 is bent such that the bottom of the bag body 52 faces down with the opening / closing member 51 facing downward. In this case, the powder 53 that has not been able to enter the measuring section 54 in the bag 52 is
Collect to the bottom of In this state, the opening / closing lid 5 of the opening / closing member 51
When 6 is opened, a certain amount of the granular material 53 stored in the measuring section 54 can be accurately taken out.

Therefore, for example, when the powder 53 is powdered milk, coffee, sugar or the like, it is possible to accurately measure a certain amount of the powder and pour it into the cup 57 or the like, which is convenient.

Next, referring to FIGS. 7 and 8, a fourth embodiment of the present invention will be described.
An embodiment will be described. FIG. 7 is a perspective view showing the slide fastener of the fourth embodiment, and FIG. 8 is a cross-sectional view taken along line CC of FIG.

The slide fastener 70 of this embodiment is for opening and closing the opening of the bag 73 composed of the sheet members 71 and 72.
