Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slider, an interlocking device with a slider, and a hermetically sealed bag provided with this interlocking device.

[0002]

BACKGROUND OF THE INVENTION Traditionally, resealable containers have been used in many packaging applications to store or enclose various types of articles and materials. These packaging bags can be used to store food products, non-food consumer products, medical supplies, waste materials, and many other items. Resealable packaging bags are convenient because they can be closed and resealed after the initial opening to hold the enclosed contents.

As a structure that can be easily resealed, a technique relating to a sealed bag using an engaging device with a slider has been proposed (WO00-28851). This articulation tool with slider is configured such that a slider having a U-shaped cross-section having a side wall and an upper wall is mounted on the upper ends of a pair of interlocking male and female engaging members. On the inside of the upper wall of the slider, there is formed a separation part for separating the pair of occlusal members. By inserting this separation part between the pair of occlusal members, the sliding of the slider opens and closes the articulation device. It can be carried out. Specifically, the separating portion is formed in a triangular prism shape having a cross section of an isosceles triangle whose bottom is the closing side end of the slider, and when the slider is moved in the opening direction of the engaging device, the oblique side portion of the triangle is formed. A pair of occlusal members are spread along and separated.

When manufacturing the sealed bag having the slider as described above, the separating portion of the slider has to be inserted between the pair of occlusal members. There is a problem that the base of the triangle interferes with the occlusal member and is difficult to insert. For this reason, conventionally, by forming a notch or notch in the slider mounting portion of the occlusal member and arranging and mounting the bottom portion of the separating portion in this portion, interference with the bottom portion has been avoided.

[0005]

However, making a notch in the occlusal member each time during manufacturing causes a problem in that the manufacturing process is increased and the manufacturing cost is increased.

An object of the present invention is to provide a slider, an engaging device with a slider, and a sealing bag provided with this engaging device, which can reduce manufacturing costs.

[0007]

In order to achieve the above object, an articulation tool provided with a pair of articulation members that interlock with each other is provided, and the pair of articulation members are slid in the extending direction of the articulation tool. A slider that opens and closes
A slider body having a U-shaped cross section including a pair of side wall portions that engage with each of the bite members at their lower ends, and an upper wall portion that connects the upper end portions of the side wall portions, and a slider body that hangs from the inside of the upper wall portion of the slider body. And a separating portion that separates the occlusal portions of the pair of occlusal members, and the separating portion is formed with a pair of inclined guide surfaces that gradually approach each other toward the distal end in the hanging direction. Further, the articulating tool with slider of the present invention is characterized by including a pair of occlusal members that occlude each other and the slider.

Here, the slider can be made of any material as long as it has flexibility. Specifically, for example, any of nylon, polypropylene, polystyrene, ABS resin or the like can be appropriately adopted depending on the purpose. Further, as the material of the engaging device with a slider, in consideration of occlusal property, fusion property to the inner surface of the bag body film, low-density polyethylene, ethylene-α-olefin copolymer,

Specifically, for example, the ridge member may have a convex shape or a semicircular shape, and may have an arbitrary shape such as a triangle or a trapezoid. In addition, the concave strip member may have a shape corresponding to the convex strip member.

According to this, since the interlocking device with the slider is provided with the contact member, the interlocking member is moved toward the opening side in the opening of the bag to which the interlocking device with the slider is attached. By setting the inner side, in addition to the sealing by the engaging device, the sealing by the contact member can be taken into consideration, so that the sealing performance can be further improved.

Further, it is preferable that the convex ridge member and / or the concave ridge member of the close contact member include an adhesive resin material. Here, as a material of the adhesion member, an ethylene-polar vinyl copolymer or a resin containing these can be preferably exemplified. Here, as the ethylene-polar vinyl copolymer, ethylene-vinyl acetate copolymer,
Examples thereof include ethylene-methacrylic acid copolymer and ethylene-ethyl acrylate copolymer. An adhesive resin material may be mixed with these materials, or only the surface may be made of the adhesive resin material.

The adhesive resin material is an ethylene / α-olefin copolymer, propylene / butene-1 / having 5 to 1 carbon atoms.
Various resins such as an α-olefin copolymer of 0, a styrene / ethylene / butylene / styrene block copolymer, a styrene / butadiene / styrene block copolymer, and a styrene / isoprene / styrene block copolymer can be exemplified. These adhesive resin materials can be appropriately selected according to the characteristics, application, size, etc. of the bag in which the articulator with slider is to be attached by combining the content of polar vinyl monomer and the compounding ratio with other resins or elastomers. It is determined.

According to this, since the convex strip member and / or the concave strip member of the close contact member is configured to contain the adhesive resin material, the close contact member has adhesiveness and can be locked. Further, it is possible to further improve the sealing property of the bag or the like provided with the slider-attached engaging device.

Characterize. In the above, when the contact member is provided on the base piece of the occlusal member that constitutes the slider-equipped occluder, the contact member is attached so as to be inside the bag as compared with the occlusal member when viewed from the opening side of the bag body. Is preferably provided. Since the contact member is provided inside the bag rather than the occlusal member, even if the bite of the pair of occlusal members is separated, it is possible to maintain the sealing by the contact member, so that impurities and the like can be prevented from the opening of the bag body. It can be prevented from being mixed.

Further, in the above-mentioned bag body, when a pair of edges of the sheets to be overlapped are opposed to each other and the edges sandwiched by the pair of the welded edges are openings, The interlocking device with a slider is preferably provided inside the bag so that the slider is hidden inside the bag. Here, the bag body is formed by folding a sheet made of one thermoplastic resin in half to form a bag,
It is possible to adopt a bag-shaped product obtained by stacking sheets of thermoplastic resin on top of each other. The thermoplastic resin is not particularly limited, but a polyolefin resin can be adopted because it is easy to mold. Examples of the polyolefin resin include polyethylene and polypropylene.

According to the present invention as described above, since the interlocking device with the slider is attached to such a depth that the slider is concealed inside the bag, after the bag is manufactured, a pair of welded edges, particularly It is possible to prevent the edge in the bag closing direction from falling off from the articulation tool.

Further, it is preferable that the above-mentioned hermetically sealed bag is provided with a deaeration part for discharging the air in the bag to the outside of the bag. Since the air inside the bag can be discharged to the outside of the bag by the degassing unit, the capacity of the sealed bag can be reduced,

The degassing section 60 is formed as a cylindrical sheet made of the same material as the sheet forming the bag body 10, and an adhesive is applied to the inside of the cylindrical shape. The degassing portion 60 is a heat seal portion 13 formed at an intermediate portion of the bag body 10, the tip of which is welded to the bag body 10,
A hose such as a vacuum cleaner can be inserted into the degassing unit 60 to discharge the air inside the sealed bag 2 to the outside. After the internal air is removed, the degassing unit 60 is removed by the adhesive applied inside.
The sheets forming the sheet adhere to each other and prevent air from entering from the outside. In other words, the degassing section 60 also has a function of a check valve for preventing backflow of air by applying an adhesive inside.

According to the second embodiment as described above, the first
In addition to the effects described in the embodiment, the following effects are provided. (1) In the opening 12 to which the articulation tool 20 is attached,
By providing the contact member 40 inside the bags of the occlusal members 21 and 22, in addition to the sealing by the occlusal device 20, the contact member 40
Since the sealing by can be added, the sealing performance can be further improved. (2) Since the bulging portions of the convex ridge member 41 and the concave ridge member 42 of the close contact member 40 are configured to include the adhesive resin material, the sealing property at the close contact portion is further improved by utilizing the property of the adhesive material. It can be improved, and impurities and the like do not enter from the opening 12 of the bag body 10. Further, unlike the case of the first embodiment, it is not necessary to weld the closing direction end portion of the articulation tool 20 for a certain length to form the seal portion.

(3) Since the deaeration part 60 is provided in the sealed bag 2, the air in the bag can be discharged to the outside. Therefore, after storing a bulky material such as a futon in the sealed bag 2,
A hose such as a vacuum cleaner can be inserted into the deaerator 60 to deaerate the internal air and reduce the size of the air, thereby reducing the storage space of the packaged object. Further, since the air in the bag is degassed by the degassing unit 60, it is possible to achieve long-term storage of foods and the like that are easily air-oxidized.

[Third Embodiment] Next, a third embodiment of the present invention will be described. In the second embodiment, the sealed bag 2
The corners of the ends in the closing direction and the opening direction on the side of the opening 12 were separated by 90 °.
