TECHNICAL FIELD OF THE INVENTION
The present invention relates to a refill staple case used for a stapler, and more particularly, to a staple case that facilitates handling and simplifies packaging.
[0002]
[Prior art]
Conventionally, when the staples in the staple cartridge of the stapler are used up, a disposable staple cartridge that replaces the entire staple cartridge is generally used, but staples are replenished to the staple cartridge to save resources and reduce waste. The shift to refillable staple cartridges that can be performed is progressing.
[0003]
Staple cartridges include those that accommodate unformed staples and accommodate them as staple packs in which flat sheet staples are stacked, and those that accommodate roll-shaped roll staples.Laminated sheet staples are made of plastic or paper. (For example, see Patent Document 1). Also, the roll staple is held in a roll shape by sticking the outer peripheral end to the outer peripheral surface of the roll with an adhesive tape, and the gap to be used is peeled off the adhesive tape, and the leading end is freely set in the cartridge. Some are known (for example, see Patent Document 2).

[Problems to be solved by the invention]
In conventional roll staples, when peeling off the adhesive tape stuck on the outer periphery of the roll staple and loading the cartridge into the cartridge, it takes time to unwind and rewind the roll staple, or the roll staple is accidentally dropped and removed. Staples may be broken and become unusable, and there is a difficulty in handling. In addition, roll staples are shipped in paper boxes and packed in the space inside the carton to prevent damage during transportation.However, after removing the roll staples from the carton, these packing materials are no longer necessary. There is also a problem that resources are wasted and wasteful. Further, for example, a container in which paper is folded such as that described in Patent Literature 1 has a problem that the stored sheet staples are broken or broken when dropped. Further, since it is difficult to determine the direction of the staples in the staple case, the staples may be loaded in the opposite direction. Therefore, there arises a technical problem to be solved in order to facilitate the handling of staples and to reduce the amount of packing material to reduce waste of resources, and an object of the present invention is to solve the above problem.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an empty staple case 1, and FIG. 2 shows a state where the leading end of a roll staple S accommodated in the staple case 1 is pulled out. The staple case 1 is vertically divided into two parts at the front and rear center. For example, a front case half 2 and a rear case half 3 are formed by means of blow molding or vacuum molding using a sheet material such as a polypropylene sheet containing calcium carbonate. Then, the roll staple S is placed in a hollow cylindrical roll staple storage chamber 4 formed by the front case half 2 and the rear case half 3, and the flange portions 2a, 3a of the front case half 2 and the rear case half 3 are placed. Glue.
[0013]
As shown in FIGS. 1 to 7, hollow pillow portions 5, 6, 7, 8 each having a substantially rectangular shape are formed on both left and right side surfaces in the roll staple storage chamber 4. When one or a plurality of staple cases 1 are accommodated in a paper box having an internal capacity matching the outer dimensions of the staple case 1, the rectangular cushion portions 5, 6, 7, 8 serve as a packing, and the staple case 1 in the paper box is provided. The cushion portions 5, 6, 7, 8 absorb the impact and prevent the roll staple S from being damaged when an external impact is applied. Also, as shown in FIG. 4, the top surfaces of the upper cushion portions 5, 7 are different from the bottom surfaces of the lower cushion portions 6, 8, and the bottom surfaces of the lower cushion portions 6, 8 are different from each other. , 7 are smaller in curvature than the upper surface.
[0014]
A staple outlet 9 is opened in the upper and lower middle part of the front surface of the roll staple storage chamber 4, and the roll staple S is pulled out from the staple outlet 9. The staple outlet 9 may be formed by forming a perforation or a thin portion in the staple case 1 and removing the portion at the time of use.
[0015]
As shown in FIGS. 1 and 4, the front surface of the front lower cushion portion 6 below the staple outlet 9 has an inclined surface facing forward and downward from the staple outlet 9 so that the staples can be smoothly drawn out. I have to. Further, on both right and left sides of the roll staple accommodating chamber 4, downward arrow marks 10 are embossed to show the direction of insertion into the staple cartridge. Further, in the center of the rear surface (left side in the figure) of the staple case 1, a vertically long cushion portion 11 having both a marking function for front / rear discrimination and an erroneous insertion prevention function is provided so that the shapes of the front and rear surfaces are different. In the above, the case where the staple case 1 is inserted into the staple cartridge has been described. However, it is needless to say that the staple case 1 may be directly inserted into the staple accommodating chamber of the stapler. Although illustration is omitted, if a fragile portion such as a perforation or a thin portion is formed in the flange portions 2a and 3a, which are bonding portions between the front case half 2 and the rear case half 3 of the staple case 1, for example, In the event that a roll staple breaks or is defective, the staple case 1 is split into a front case half 2 and a rear case half 3 to take out the roll staple S, and the staple case 1 and the roll staple S And can be discarded separately.
[0016]
FIG. 8 shows a state in which the staple case 1 is loaded in the staple cartridge C. The inside of the staple cartridge C has a shape and dimensions corresponding to the staple case 1, and it is not necessary to open the roll staples. The staple case 1 can be loaded directly, and loading is extremely simple.
[0017]
Further, the bottom surface is a concave surface conforming to the shape of the lower cushion portions 6 and 8, and a projection 12 for preventing erroneous insertion is provided at the left and right center of the front wall surface of the staple storage chamber. Therefore, when the staple case 1 is inserted upside down, the staple case 1 is not completely inserted into the staple accommodating chamber, and the upper lid of the staple cartridge C cannot be closed. Further, when the staple case 1 is inserted with the front and rear directions reversed, the cushion portion 11 at the center of the rear surface of the staple case 1 hits the convex portion 12 and cannot be inserted, thereby preventing erroneous insertion.
[0018]
FIG. 9 shows another embodiment, which is a staple case 21 in which sheet staples are stacked and accommodated. The staple case is formed by bulging four ridges to form a cushion portion 22, and a cushion formed by a case half flange on the top and bottom surfaces. A portion 23 is formed. The opening 24 on the upper surface is for inserting a pressing portion (not shown) provided on the stapler to be loaded, and the reference numeral 25 is for pulling a sheet staple appearing by removing a portion surrounded by a fragile portion such as a perforation. Exit. Also in this staple case, the sheet staples accommodated at the time of dropping or transporting do not come apart, and the staple case and the staple case 21 can be loaded.
[0019]
It should be noted that the present invention is not limited to the above embodiments, and various modifications are possible within the technical scope of the present invention, and it is natural that the present invention extends to those modified ones.
[0020]
【The invention's effect】
As described above, since the staple case of the present invention is provided with the staple draw-out port and can be directly loaded into the staple cartridge, the work of replenishing staples into the staple cartridge is extremely simple, and it is necessary to make the roll staples naked. Since there is no staple, the risk of breakage of the roll staple when replenishing staples is eliminated. Further, since the staple case is provided with a cushion portion at a corner portion and is substantially square, there is no need to pack packing in the packing box, which is effective in cost reduction and resource saving. In addition, the front and back sides of the staple case, as well as the top and bottom sides, have different shapes so that they cannot be inserted into the case storage section of the cartridge in the wrong direction, simplifying the staple filling operation and preventing insertion errors. it can.
