Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fastener used for temporarily fixing a lid of a relatively thick paper bag, a cardboard box or the like.

[0002]

[Prior art]

 To temporarily secure a lid that can be opened and closed like a cardboard box, a stopper is provided on both lid pieces that are in contact with each other, and a string is wound between both stoppers. In addition, hooks are provided at both ends of the strip toward the inside, so that the strips abut on the lids that are in contact with each other, insert the hooks into the respective lids, and engage with the back of the lid. It has stopped.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional temporary fastening by winding the string is time-consuming and time-consuming, and in the temporary fastening using the hook portion, there is an insertion hole for inserting and removing the hook portion. There is a problem that there is rattling. The present invention solves such a problem, and its purpose is that it can be mounted on a cardboard box, a paper bag, etc. without being so bulky, and can be stopped and removed by a one-touch operation, and it can be used for a considerable number of times. The object of the present invention is to provide a fastening device for a lid that can withstand.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a lid fastening device, which is a feature of the present invention, is a plastic tightening band having one end formed in a fixing portion, a locking plate for locking the tightening band, and a locking plate. The fastening plate is provided with a stop plate and a stop piece used to fix the fixed part on the attached parts of the both members, and the edge of the tightening band on the front side is formed in the notched part, while the engagement part is formed. The stop plate is provided with a tunnel-shaped passage through which the tightening band can be inserted, and an engaging portion that is engaged and disengaged with the notched portion is provided on the outlet side of the passage.

Then, in order to increase elasticity of a portion of the tightening band which faces the notched portion, a window hole is provided at the portion so that the notched portion and the locking portion can be engaged and disengaged without trouble. preferable. Further, it is preferable that the upper surface of the locking plate is formed into a flat central surface portion and an inclined surface portion that gently descends from the central surface portion toward the peripheral edge so that apparent bulkiness is reduced.

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. Reference numeral 1 is a plastic tightening band, one end of which is formed in an enlarged fixing portion 2, and a pair of stopper shafts 3 are provided on the rear surface side of the fixing portion 2.

The tightening band 1 is formed with serrated notches 4 and 4 at both edges on the front side, and 4a is a valley part and 4b is gently lowered toward the tip 1a side of the tightening band 1. It is an inclined part. In addition, the tightening band 1 is provided with a window hole 1b in the portion facing the notch 4 in order to enhance elasticity.

Reference numeral 5 denotes a locking board provided with a tunnel-shaped passage 6 through which the tightening band 1 can be inserted, and the passage 6 has an outlet 6a side which is detachable from the notches 4 and 4 of the tightening band 1. Claw-shaped engaging portions 7, 7 are provided so as to face each other, and a pair of stopper shafts 8, 8 are provided on the rear surface side of the engaging plate 5 so as to project. The locking board 5 is formed with a flat central surface portion 5a and an inclined surface portion 5b gently descending from the central surface portion 5a toward the peripheral edge 5c so that the bulkiness of the locking plate 5 becomes small. The front part and the front part of the passage 6 are chamfered.

Reference numeral 9 is a prepared stopper piece for fixing each of the fixing portion 2 of the tightening band 1 and the locking board 5 to the attached portion (lid piece of a corrugated box, etc.) 11 described above. Used for. The stopper piece 9 is provided with an insertion hole 9a for fitting the stopper shafts 3 and 8 described above. The locking plate 5 and the stopper piece 9 are also made of plastic.

Next, the temporary fixing of the lid according to the embodiment will be described. The fixing portion 2 of the tightening band 1 is attached to one of the pair of lid pieces shown as the attached portion 11 by the stop shaft 3 and the stop piece 9, and the locking plate 5 is attached on the other side by the stop shaft 8 and the stop piece 9, respectively. Fix it. Then, when the tightening band 1 is inserted into the passage 6 formed in the locking plate 5, both lid pieces are temporarily fixed by the locking action of the notched portion 4 and the locking portion 7 (see FIG. 2). ).

On the other hand, in order to release the temporary fixing, the tightening band 1 may be pulled out from the locking plate 5, and this pulling out operation is performed by locking the notched portion 4 facing the window hole 1b and the locking portion 7. By removing the, one-touch operation becomes possible. In order to prevent the tightening band 1 from being excessively inserted into the locking board 5, a stopper 1c is provided on the edge of the tightening band 1 so that the stopper 1c can abut the corner 5d of the locking board 5. There is. In the figure, 3a and 8a are engaging portions for connecting the stopper piece 9 to the stopper shafts 3 and 8.

In addition, in order to apply the present fastener to a corrugated cardboard box, it is necessary to use a machined screw on the retaining shafts 3 and 8 and a female screw portion on the retaining piece 9. I want to use it. Although not shown in the drawings, the present fastener uses a double-sided adhesive tape instead of the above-mentioned stop piece 9, and the double-sided tape is used to attach the stop piece in advance to the fixing portion 2 and the back surface of the locking board 5. It can also be adhered to the surface of the fixed part 2 and the fixing part 2 can be fixed easily and quickly, and the fixing part 2 and the stop shafts 3 and 8 of the locking plate 5 are unnecessary. There are advantages.

[0013]

[Effect of device]

 The present invention is as described above, and in particular, the locking board is formed with a flat central surface portion and an inclined surface portion gently descending from the central surface portion toward the peripheral edge so that the locking plate is not so bulky to mount. Since it is possible, it is possible to eliminate problems such as being caught when stacking boxes whose lids are temporarily fixed by a fastener. Moreover, its practical value is extremely large, as it has the advantage of being able to withstand a considerable number of times of use and can be removed with one-touch operation.
