Description

この発明は、例えば包丁、鋏、ナイフ等の刃物、或いは、調理器具、雑貨品、文房具、部品、食品等の被収容物を販売する際に用いられるプラスチックケースの封印方法及びその封印部材に関する。   The present invention relates to a sealing method and a sealing member for a plastic case used when selling stored objects such as knives, scissors, knives, etc., or utensils such as cooking utensils, miscellaneous goods, stationery, parts, foods and the like.

前記包丁や鋏等を透明なプラスチックケースに収容して販売する場合、プラスチックケースに収容された包丁や鋏が簡単に取り出せない方法が採用されている。   In the case where the kitchen knife or the bag is stored in a transparent plastic case for sale, a method is employed in which the knife or bag stored in the plastic case cannot be easily taken out.

その方法としては、図１７の（ａ）に示すように、プラスチックケース２０の上端側開口部の前側縁部に連設された上蓋部２１と、上端側開口部の後側縁部に連設された支持部２２との重ね合わせ部分を、例えば超音波溶着、高周波溶着、熱圧着、レーザー溶着等の熱溶着手段により熱溶着２６して封印する方法がある。また、プラスチックケース２０の上端側開口部を閉塞する上蓋部２１上に、粘着テープ２７を貼着して封印する方法がある。また、図１７の（ｂ）に示すように、プラスチックケース２０の上端側開口部の前側縁部に連設された上蓋部２１を後方へ折曲げて、上端側開口部の後側縁部に連設された支持部２２に重ね合わせた後、上蓋部２１と支持部２２との重ね合わせ部分に形成された複数の孔部２３…を介して、一対の封印部品２４，２５を互いに嵌着することで封印する方法がある。また、上方から見て４角形に組み立てられた箱の開口部を４角形蓋板で閉鎖し、４角形蓋板の両端部に形成された各小舌片を、箱の底板両側部に形成された各差込孔に挿入して封印する特許文献１の果実箱がある。   As the method, as shown in FIG. 17A, the upper lid portion 21 connected to the front edge of the upper end opening of the plastic case 20 and the rear edge of the upper end opening are continuously provided. There is a method in which the overlapped portion with the support portion 22 is sealed by heat welding 26 using heat welding means such as ultrasonic welding, high frequency welding, thermocompression bonding, laser welding, or the like. Further, there is a method of sticking and sealing the adhesive tape 27 on the upper lid portion 21 that closes the upper end side opening of the plastic case 20. Also, as shown in FIG. 17 (b), the upper lid 21 connected to the front edge of the upper end opening of the plastic case 20 is bent backward to form the rear edge of the upper end opening. After overlapping the support part 22 provided continuously, the pair of sealing parts 24 and 25 are fitted to each other through a plurality of holes 23 formed in the overlapping part of the upper lid part 21 and the support part 22. There is a method of sealing by doing. Moreover, the opening part of the box assembled into the quadrangular shape as viewed from above was closed with the quadrangular lid plate, and the small tongue pieces formed on both ends of the quadrangular lid plate were formed on both sides of the bottom plate of the box.

実開昭５２−１５５１２４号公報Japanese Utility Model Publication No. 52-155124

前記熱溶着２６により封印する場合、熱溶着２６するための熱溶着装置を設置する必要があり、１つのプラスチックケース２０を封印する作業に手間及び時間が掛かるだけでなく、熱溶着装置が設置された所定の場所でしか封印作業が行えないため、作業性が悪い。また、粘着テープ２７により封印する場合、粘着テープ２７を簡単に剥離することができるので、刃物や鋏等の被収容物が抜き取られるのを防止する効果が薄い。   When sealing by the heat welding 26, it is necessary to install a heat welding device for performing the heat welding 26, and not only the work for sealing one plastic case 20 takes time and labor, but also a heat welding device is installed. In addition, since the sealing work can be performed only at a predetermined place, workability is poor. Moreover, when sealing with the adhesive tape 27, since the adhesive tape 27 can be peeled easily, the effect which prevents to-be-contained objects, such as a blade and a scissors, is thin.

また、一対の封印部品２４，２５により封印する場合、封印部品２４，２５を互いに嵌着するための孔部２３…を、上蓋部２１と支持部２２との重ね合わせ部分に複数個設けなければならず、孔部２３の加工作業に手間及び時間が掛かる。また、孔部２３を加工する際に発生する打抜き片を手作業により１個ずつ除去しなければならず、加工費が高くなる。また、封印部品２４，２５を製作する際に用いられる射出成形機の電気代が高く、部品代として高価なものとなる。及び、封印部品２４，２５の嵌着作業にも手数を要する。   Further, when sealing with a pair of sealing parts 24, 25, a plurality of hole portions 23 for fitting the sealing parts 24, 25 to each other must be provided in the overlapping portion of the upper lid part 21 and the support part 22. In other words, it takes time and effort to process the hole 23. Further, the punched pieces generated when the hole 23 is processed must be manually removed one by one, which increases the processing cost. In addition, the electricity cost of the injection molding machine used when manufacturing the sealed parts 24 and 25 is high, and the parts cost is expensive. In addition, it takes time to fit the sealing parts 24 and 25.

また、特許文献１の果実箱は、４角形蓋板により箱の開口部を直接閉鎖するので、例えば蓋部外面に封印部材を装着するよりも構造的強度が弱く、蓋板を破るだけで、箱の開口部が簡単に開口されてしまう。また、蓋板の前後端部には小舌片がなく、蓋板の前後端部と、箱の前後縁部との隙間から手を差し込んで、箱内に収容された果実等を抜き取ることが可能である。   Moreover, since the fruit box of Patent Document 1 directly closes the opening of the box with a quadrangular lid, the structural strength is weaker than, for example, mounting a sealing member on the outer surface of the lid. The opening of the box is easily opened. In addition, there are no small tongue pieces at the front and rear ends of the lid plate, and it is possible to pull out the fruit stored in the box by inserting a hand through the gap between the front and rear end portions of the lid plate and the front and rear edge portions of the box It is.

The notches 3d and 3d are locked to both side edges of the insertion hole 1J to prevent it from being removed (see FIG. 9).

封印部材３の両側短辺部に連設された差込み片３Ｂ，３Ｂを、側面部１Ｂａ，１Ｂｂと折込み部１Ｅ，１Ｅとの折り曲げ部分に形成された差込み孔１Ｋ，１Ｋに差し込み、差込み片３Ｂの両側縁部に形成された切込み部３ｄ，３ｄを差込み孔１Ｋの両側縁部に係止して抜止めする（図９参照）。これにより、ケース本体１ａの上端側開口部１ｂを閉塞する上蓋部１Ｆ及び折込み部１Ｅ，１Ｅが開けられないように封印している。   The insertion pieces 3B and 3B connected to the short side portions on both sides of the sealing member 3 are inserted into insertion holes 1K and 1K formed in the bent portions of the side surface portions 1Ba and 1Bb and the folding portions 1E and 1E, and the insertion piece 3B is inserted. The notches 3d and 3d formed on the both side edges are locked to the both side edges of the insertion hole 1K to prevent removal (see FIG. 9). Thus, the upper lid 1F and the folded portions 1E, 1E that close the upper end side opening 1b of the case body 1a are sealed so that they cannot be opened.

ケース本体１ａの下端側開口部１ｃを閉塞する下蓋部１Ｇ，１Ｉが開けられないように封印部材４で封印する場合、図５に示す封印部材４の一側短辺部と両側長辺部を、各部の折り曲げ部分に形成した折り曲げ罫線２に沿って上方に向けて起立する状態に折り曲げた後、下蓋部１Ｇ，１Ｉによって閉塞されたケース本体１ａの下端側開口部１ｃの角隅部外面に対して下方から装着する（図６、図８参照）。   In the case of sealing with the sealing member 4 so that the lower lid portions 1G and 1I closing the lower end side opening 1c of the case body 1a cannot be opened, one short side and both long long sides of the sealing member 4 shown in FIG. Is bent in a state of standing upward along the folding ruled line 2 formed in the bent portion of each part, and then the corner corner portion of the lower end side opening 1c of the case body 1a closed by the lower lid portions 1G and 1I. It is mounted on the outer surface from below (see FIGS. 6 and 8).

封印部材４の一側短辺部に連設された差込み片４Ａを、ケース本体１ａの前面部１Ａの下端側外面に形成された差込み孔１Ｎに差し込み、差込み片４Ａの両側縁部に形成された切込み部４ｄ，４ｄを差込み孔１Ｎの両側縁部に係止して抜止めする（図９参照）。   The insertion piece 4A connected to the short side of one side of the sealing member 4 is inserted into the insertion hole 1N formed on the outer surface on the lower end side of the front surface portion 1A of the case body 1a, and formed on both side edges of the insertion piece 4A. The notches 4d and 4d are locked to both side edges of the insertion hole 1N to prevent it from being removed (see FIG. 9).

また、封印部材４の両側長辺部に連設された差込み片４Ｂ，４Ｂを、前面部１Ａ及び後面部１Ｃの下端側外面に形成された差込み孔１Ｍ，１Ｍに差し込み、差込み片４Ｂの両側縁部に形成された切込み部４ｄ，４ｄを差込み孔１Ｍの両側縁部に係止して抜止めする（図９参照）。これにより、ケース本体１ａの下端側開口部１ｃを閉塞する下蓋部１Ｇ，１Ｉが開けられないように封印している。   Further, the insertion pieces 4B and 4B connected to the long side portions on both sides of the sealing member 4 are inserted into the insertion holes 1M and 1M formed on the lower end side outer surfaces of the front surface portion 1A and the rear surface portion 1C, and both sides of the insertion piece 4B are inserted. The notches 4d, 4d formed at the edge are locked to both side edges of the insertion hole 1M to prevent the removal (see FIG. 9). Thus, the lower lid portions 1G and 1I that close the lower end side opening portion 1c of the case main body 1a are sealed so as not to be opened.

以上のように、ケース本体１ａの上端側開口部１ｂを閉塞する上蓋部１Ｆ及び折込み部１Ｅ，１Ｅが開けられないように封印部材３で封印し、下端側開口部１ｃを閉塞する下蓋部１Ｇ，１Ｉが開けられないように封印部材４で封印するので、ケース本体１ａに収容された刃物Ｚが抜け落ちるか、刃物Ｚが抜き取られるのを防止することができる。また、上端側開口部１ｂを閉塞する上蓋部１Ｆ外面に封印部材３を装着し、下端側開口部１ｃを閉塞する下蓋部１Ｇ外面に封印部材４を装着して封印するので、特許文献１のように蓋板のみで閉塞するよりも開けにくく、封印状態を維持するのに必要な構造的強度が得られる。   As described above, the upper lid portion 1F and the folding portions 1E and 1E that close the upper end side opening 1b of the case body 1a are sealed with the sealing member 3 so as not to be opened, and the lower lid portion that closes the lower end side opening 1c. Since sealing is performed by the sealing member 4 so that 1G and 1I cannot be opened, it is possible to prevent the cutter Z accommodated in the case body 1a from falling off or being pulled out. Further, since the sealing member 3 is attached to the outer surface of the upper lid portion 1F that closes the upper end side opening 1b, and the sealing member 4 is attached to the outer surface of the lower lid portion 1G that closes the lower end side opening 1c, sealing is performed. Thus, it is harder to open than closing with only the lid plate, and the structural strength necessary to maintain the sealed state can be obtained.

また、封印部材３の差込み片３Ａ，３Ｂ，３Ｂを、ケース本体１ａの上端側開口部１ｂに近い差込み孔１Ｊ，１Ｋ，１Ｋに差し込み、封印部材４の差込み片４Ａ，４Ｂ，４Ｂを、ケース本体１ａの下端側開口部１ｃに近い差込み孔１Ｎ，１Ｍ，１Ｍに差し込むだけの簡単な封印構造であるので、封印作業が簡単且つ容易に行えるだけでなく、組立作業及び封印作業に要する時間が短くなり、作業の能率アップを図ることができる。また、封印装置等が不要となるため、封印作業が所望する場所で行え、作業性が向上する。   Further, the insertion pieces 3A, 3B, 3B of the sealing member 3 are inserted into the insertion holes 1J, 1K, 1K close to the upper end side opening 1b of the case body 1a, and the insertion pieces 4A, 4B, 4B of the sealing member 4 are inserted into the case. Since the sealing structure is simply inserted into the insertion holes 1N, 1M, 1M close to the lower end side opening 1c of the main body 1a, not only can the sealing work be performed easily and easily, but also the time required for the assembly work and the sealing work. It becomes shorter and can improve work efficiency. Further, since a sealing device or the like is not required, the sealing work can be performed at a desired place, and workability is improved.

また、封印部材３，４をケース本体１ａの開口部１ｂ，１ｃ外面に沿って装着するので、外観上の見栄えが向上する。また、ケース本体１ａの構造を変更する必要が無く、ケース本体１ａを製作する際に要するコストの低減を図ることができる。また、ケース本体１ａ及び封印部材３，４を安価な型で製作することができる。   Moreover, since the sealing members 3 and 4 are mounted along the outer surfaces of the openings 1b and 1c of the case main body 1a, the appearance of the appearance is improved. Further, it is not necessary to change the structure of the case main body 1a, and the cost required for manufacturing the case main body 1a can be reduced. Further, the case main body 1a and the sealing members 3 and 4 can be manufactured with an inexpensive mold.

また、プラスチックケース１を製作するための製造機を用いて、封印部材３，４を製作することができるという利点を有している。また、封印部材３，４の型抜きもトムソン型の製造機を用いるため、従来例の封印部品２４，２５を製作する際の数％の製作費で製作することができる。   In addition, the sealing members 3 and 4 can be manufactured using a manufacturing machine for manufacturing the plastic case 1. In addition, since the Thomson type manufacturing machine is used for die cutting of the sealing members 3 and 4, the sealing members 24 and 25 of the conventional example can be manufactured at a manufacturing cost of several percent.

また、封印部材３，４を、プラスチックケース１を構成するプラスチックシートの肉厚より厚いシートで製作することにより、より強固に封印することができる。   Further, when the sealing members 3 and 4 are made of a sheet thicker than the thickness of the plastic sheet constituting the plastic case 1, the sealing members 3 and 4 can be sealed more firmly.

また、ケース本体１ａの大きさ及び形状に応じて、封印部材３，４を所望する肉厚に変更することができ、封印するのに適した肉厚の封印部材３，４を選定することができる。   Further, according to the size and shape of the case body 1a, the sealing members 3 and 4 can be changed to a desired thickness, and the sealing members 3 and 4 having a thickness suitable for sealing can be selected. it can.

なお、ケース本体１ａの下蓋部１Ｇ，１Ｉと封印部材４を、ケース本体１ａの下端側開口部１ｃの全体が閉塞される大きさ及び形状に形成してもよい。   Note that the lower lid portions 1G and 1I and the sealing member 4 of the case main body 1a may be formed in a size and shape so that the entire lower end side opening 1c of the case main body 1a is closed.
