- the experimental material “LDPE”, “Novatec LJ802” manufactured by Nippon Polyethylene Co., Ltd., “Halolex NJ664N” manufactured by Nippon Polyethylene Co., Ltd. as “Metalocene PE”, and “PP” as manufactured by Nippon Polypro Co., Ltd. “M6900” manufactured by Keiyo Polyethylene Co., Ltd. was used as “HDPE”.
- the material of the sheet part 61 was polypropylene, the sheet part 61 was mounted at a predetermined position of the movable side mold, and the outer frame part 70 was primarily formed of metallocene polyethylene which is a different resin.
- the situation when the experiment was performed by changing the injection molding temperature of the primary injection molding from 180 ° C. to 250 ° C. is the result of the above experiment, and the polypropylene and the metallocene polyethylene can be substantially welded at 180 ° C. to 250 ° C. I understood that.
- the injection molding temperature is preferably 200 ° C. to 240 ° C., more preferably 210 ° C. to 230 ° C.
- the injection molding temperature at the time of secondary molding can be molded at a temperature lower by 10 ° C. to 30 ° C. than at the time of primary molding. Accordingly, the injection molding temperature at the time of secondary molding is 170 ° C. to 240 ° C., preferably 180 ° C. to 205 ° C., more preferably 180 ° C. to 200 ° C.
- the adhesion with 61 can be controlled. At that time, the secondary molding temperature can be easily controlled by molding at a temperature slightly lower than the primary molding temperature by 10 ° C. to 30 ° C.
- Examples of the polypropylene of the sheet portion 61 include those shown in Table 1 below.

- a plurality of discharge members 50 were prepared so that the PP sheet portion 61 and the metallocene PE outer frame portion 70 had different adhesion (welding) strengths.
- Nylon / polyethylene tubular portions 51 (tubes) having a folding diameter of 120 mm and a length of 200 mm are welded to these discharge members 50, and 700 g of water is filled in these tubular portions 51 so that no air remains as much as possible.
- the cylindrical part 51 was sealed and the sample of the container 1 was created.
- a drop test was performed in which the water-filled container 1 was dropped from a height of 90 cm onto a hard concrete floor.
- the evaluation is ⁇ when optimal adhesiveness with no water leakage is obtained, ⁇ when usable adhesiveness without water leakage is obtained, and may cause some problems in use
- the case where the adhesiveness felt to be obtained was ⁇ , and the case where an unusable adhesiveness with slight water leakage was obtained was indicated as x.
- Test 2 penetrant check
- the red penetrant was applied to the adhesion part between the sheet part 61 and the outer frame part 70 of the container 1 that was ⁇ , ⁇ or ⁇ in the drop test, and then left to stand for 30 minutes. The penetration state of the red penetrant into the welded portion of 70 was confirmed. It was confirmed again after 24 hours.
- AGELESS seal check spray manufactured by Mitsubishi Gas Chemical Co., Ltd. was used as the osmotic spray.
- Test 3 welding strength tensile test
- 20 discharge members 50 prepared under the same conditions as those of the container 1 that was ⁇ , ⁇ , or ⁇ in the drop test are prepared, and the discharge member 50 is turned upside down as shown in FIG.
- seat part 61 was pulled until the welding part of the sheet
- the reason why the welding width is not set to 100% is to delete the numerical value when a partial welding portion remains.
- the value of the tensile strength shown in FIG. 11 is a numerical value obtained by averaging the experimental results of 20 discharge members 50. Evaluation is ⁇ when optimal adhesiveness and sealability are obtained, ⁇ when usable adhesiveness and sealability are obtained, and adhesion that seems to cause some problems in use When the property and the sealing property were obtained, ⁇ , and when the unusable adhesive property and the sealing property were obtained, the symbol was ⁇ .
- the test specifications are as follows. Test equipment: Orientec Co., Ltd. Tensilon RTC-1225 Test method: T-type peel strength test Test speed: 50mm / min
- Test 4 Visual inspection of shape
- the molding state (sink marks, liquid flow, etc.) of the discharge member 50 was visually confirmed. Evaluation is ⁇ when an optimal molding state without sink marks is obtained, ⁇ when a usable molding state is obtained, and a molding state that seems to cause some problems in use. The case where it was obtained was indicated by ⁇ , and the case where an unusable molding state was obtained was indicated by ⁇ .
- the welding conditions for the PP sheet portion 61 and the metallocene PE outer frame portion 70 preferred ones can be selected from the results of the drop test, the permeation liquid check, the tensile strength test, and the shape visual inspection.
- the drop test of Test 1 is not unusable although it seems that there may be some problems in use when the tensile strength is 3 N / 15 mm. If the strength is 6 N / 15 mm or more, usable adhesiveness is secured. Furthermore, the best result is obtained in the case of 23 N / 15 mm or more.
- the test 2 penetrant check is similar to the test 1 drop test.
- the tensile strength test of Test 3 shows that there may be some problems in use when the tensile strength is 6 N / 15 mm, but it is not impossible to use, but there is no problem in use at 15 N / 15 mm, and 23 N / 15 mm. If it is above, the best result will be obtained, and if the number is large, it can be understood that there is no upper limit.
- Test 4 The shape visual inspection of Test 4 is a check of the molding condition (sink, warp, etc.), which is different from the functions of adhesive strength and sealability. Although it is felt that there may be some problems in use when the tensile strength is 3 N / 15 mm, it is not impossible to use. If the tensile strength is 6 N / 15 mm or more, usable adhesiveness is ensured. Furthermore, the best result is obtained in the case of 15 N / 15 mm or more. However, unlike the tests 1 to 3 described above, the tensile strength of 100 N / 15 mm is not an optimal state, and has been lowered to a usable state.
- a tensile strength of 6 N / 15 mm or more can be used in terms of adhesive strength and sealing performance, and a more preferable range is 15 N / 15 mm or more.
- the upper limit in this case cannot be specified.
- a preferable range as the welding condition is a range where the tensile strength is 15 N / 15 mm to 100 N / 15 mm.
- the discharge member 51 having a certain level of function of the container 1. Since the outer frame portion 70 and the cylindrical portion 51 can be reliably welded by selecting the same material, the drop strength can be ensured by selecting a composite resin as the material of the cylindrical portion 51. .
- the present invention it is useful for stably discharging a food content in a desired amount in a discharge member of a container attached to a dispenser.

Abstract
Description
(1)射出成形温度が180℃、190℃の場合、シート部と外枠部との溶着は弱い。
(2)射出成形温度が200℃の場合、シート部と外枠部との溶着はやや良いが強くない。
(3)射出成形温度が210℃、220℃の場合、シート部と外枠部との溶着は強く溶着している。
(4)射出成形温度が230℃、240℃の場合、シート部と外枠部との溶着はさらに強く溶着している。
(5)射出成形温度250℃以上の場合、シート部と外枠部との溶着は強いが、ヒケや反りが発生しやすくなり、成形不良の原因となる。
従って、一次成形では射出成形温度を200℃~240℃が好ましいが、より好ましくは、210℃~230℃が望ましい。
テスト1では、先ず、PPのシート部61とメタロセンPEの外枠部70が異なる接着(溶着)強度になるように吐出部材50を複数作成した。これらの吐出部材50に、折り径120mm、長さ200mmのナイロン/ポリエチレンの筒状部51(チューブ)を溶着し、これらの筒状部51内に700gの水を充填し極力エアーが残らないように筒状部51を密封して容器1のサンプルを作成した。水入りの容器1を高さ90cmの高さから堅固なコンクリートなどの床に落下させる落下試験を行なった。評価は、水漏れが全くない最適な接着性が得られた場合を◎、水漏れが認められない使用可能な接着性が得られた場合を○、使用上多少の問題を生じる可能性があると感じられた接着性が得られた場合を△、水漏れがわずかでも認められた使用不可能な接着性が得られた場合を×とした。
テスト2では、落下試験で◎、○または△であった容器1のシート部61と外枠部70の接着部分に赤色浸透液を塗布し、その後30分放置し、シート部61と外枠部70の溶着部への赤色浸透液の浸透状態を確認した。さらに24時間後にも再度確認した。浸透液スプレーとして、三菱ガス化学株式会社製エージレス シールチェックスプレーを使用した。評価は、溶着部に浸透液の進入が全くない最適な接着性が得られた場合を◎、溶着部に浸透液の進入が認められない使用可能な接着性が得られた場合を○、使用上多少の問題を生じる可能性があると感じられた接着性が得られた場合を△、使用不可能な接着性が得られた場合を×とした。
テスト3では、先ず、落下試験で◎、○または△であった容器1と同条件で作成した吐出部材50を20個準備し、図12に示すように吐出部材50を、裏面が上を向くように引っ張り試験機で保持し、所定位置の溶着部分で幅15mmとなる短冊状に切られたシート部61を上方に引っ張る。そして、シート部61と外枠部70の溶着部が溶着幅の0%から50%乃至80%剥がれるまでシート部61を引っ張り、最大値を引っ張り強度とした。溶着幅の100%としない理由は部分的な溶着部分が残った場合の数値を削除するためである。
試験器具:株式会社オリエンテック テンシロンRTC-1225
試験方法:T型剥離強度試験
試験速度:50mm/min
テスト4では、吐出部材50の成形状況(ヒケ、液流れ他)を目視で確認した。評価は、ヒケなどがない最適な成形状態が得られた場合を◎、使用可能な成形状態が得られた場合を○、使用上多少の問題を生じる可能性があると感じられた成形状態が得られた場合を△、使用不可能な成形状態が得られた場合を×とした。
