Description
本発明は、合成樹脂製キャップ及びその製造方法に関し、より詳細には、容易に開封可能な合成樹脂製キャップに関する。 The present invention relates to a synthetic resin cap and a method for producing the same, and more particularly to a synthetic resin cap that can be easily opened.
従来、特に食料品等の分野では、内容物の品質等を保持するために容器内外の流通を防止する手段として上蓋がヒンジ結合された合成樹脂製キャップ（ヒンジキャップ）が用いられている。この様なヒンジキャップは、スコア等の弱化部が形成された開口予定部が形成されており、開口予定部に立設されたプルリング等を引っ張り、弱化部を破断して開口予定部を除去することで内容物の取り出しが可能となるものであった。しかしながら、この開口予定部の除去は、子供や高齢者等の手の力が弱い者にとっては容易といえるものではなかった。 Conventionally, in the field of foodstuffs and the like, a synthetic resin cap (hinge cap) with a hinged upper lid is used as a means for preventing the inside and outside of the container from flowing in order to maintain the quality of the contents. Such a hinge cap has a planned opening portion in which a weakened portion such as a score is formed, and pulls a pull ring or the like standing on the planned opening portion to break the weakened portion and remove the planned opening portion. Thus, the contents can be taken out. However, the removal of the planned opening portion has not been easy for a person with weak hand power such as a child or an elderly person.
一方、この開口予定部は、容器内外の流通を防ぐばかりでなく、ヒンジキャップを容器本体に装着する際に内容物がキャップ内に飛散することを防止する等の衛生上の観点からも重要なものであるため、開口予定部そのものをなくすことは困難である。そこで、特許文献１に開示された様な需要者が最初に上蓋を開蓋する際に当該開蓋と共に開封できるヒンジキャップが提案されている。 On the other hand, the planned opening portion is important not only from the inside and outside of the container but also from the viewpoint of hygiene such as preventing the contents from scattering into the cap when the hinge cap is attached to the container body. Therefore, it is difficult to eliminate the planned opening portion itself. Therefore, a hinge cap that can be opened together with the lid when a consumer like the one disclosed in Patent Document 1 first opens the top lid has been proposed.
特許文献１に開示されたヒンジキャップは、開口予定部に立設された係合壁を上蓋に垂設された垂下片に係合させることによって、上蓋の開蓋と共に係合壁ごと開口予定部を引っ張り上げることで弱化部を破断して開口予定部を除去するものである。 The hinge cap disclosed in Patent Document 1 engages an engagement wall erected on the planned opening portion with a hanging piece suspended from the upper lid, thereby opening the upper lid together with the engagement wall. By pulling up, the weakened part is broken and the planned opening part is removed.
しかしながら、特許文献１に開示されたヒンジキャップにおいては、ヒンジキャップは、上蓋が開蓋した状態で成形されると共に上蓋がヒンジを支点として回動されることによって閉蓋されるものであるため、係合壁を垂下片と係合させる際に、先ず、垂下片が係合壁に斜め方向から部分的に当接されることとなる。そのため、弱化部に局所的な負荷が掛ってしまいキャップの製造時に当該弱化部が破断する可能性がある、即ち、当該キャップが装着された容器の内外が連通してしまい、内容物の品質を保持できなくなる可能性があるという問題があった。 However, in the hinge cap disclosed in Patent Document 1, the hinge cap is formed with the upper lid opened, and the upper lid is closed by being rotated about the hinge as a fulcrum. When engaging the engaging wall with the hanging piece, first, the hanging piece is brought into partial contact with the engaging wall from an oblique direction. Therefore, a local load is applied to the weakened portion, and the weakened portion may break during the manufacture of the cap, i.e., the inside and outside of the container with the cap attached communicate with each other, and the quality of the contents is reduced. There was a problem that it may become impossible to hold.
そこで、本発明は、合成樹脂性キャップを製造する際に、開口予定部に形成された弱化部が破断することを防止しつつ需要者が最初に上蓋を開蓋する際に当該開蓋と共に容易に
開封できる合成樹脂製キャップを提供することを目的とする。
Therefore, when manufacturing a synthetic resin cap, the present invention prevents the weakened portion formed in the planned opening portion from breaking and easily opens together with the opening when the customer first opens the upper lid. An object of the present invention is to provide a synthetic resin cap that can be opened.
本発明は、蓋部と、該蓋部が結合される中栓部と、を備え、該中栓部は、開口予定部を有し、該開口予定部は、弱化部を介して連結された分離片を有し、該分離片は、凸起部と、孔部とを有しており、該蓋部は、上蓋と、該上蓋がヒンジ部を介して連結された基部とを有し、該基部は、その底壁に該分離片が挿入可能に形成された挿入口部を有し、該上蓋は、天壁を有すると共に該天壁の内面には、掛止部と、該掛止部よりも内方に設けられたガイド突起とが設けられ、該掛止部は、該凸起部と掛合可能に設けれ、該ガイド突起は、該孔部に挿入可能に設けられており、該蓋部が該中栓部に結合された際に、該ガイド突起が該孔部に挿入されると共に該凸起部と該掛止部とが掛合することを特徴とするキャップである。 The present invention includes a lid portion and an inner plug portion to which the lid portion is coupled. The inner plug portion has a planned opening portion, and the planned opening portion is connected via a weakening portion. The separation piece has a protruding portion and a hole portion, the lid portion has an upper lid, and a base portion to which the upper lid is connected via a hinge portion, The base portion has an insertion port formed in the bottom wall so that the separation piece can be inserted, and the upper lid has a top wall, and an inner surface of the top wall has a latching portion and the latching portion. A guide protrusion provided inward of the portion, the hook portion is provided so as to be hookable with the protruding portion, and the guide protrusion is provided so as to be insertable into the hole portion, The cap is characterized in that when the lid portion is coupled to the inner plug portion, the guide protrusion is inserted into the hole portion, and the protruding portion and the latching portion are engaged with each other.
本発明は、前記分離片を、前記凸起部及び前記孔部が形成された頂部を有するものとし、該頂部を、前記キャップの前記ヒンジ部とは反対側の偏心位置に位置する様に設けられるものとすることができる。又、本発明は、前記上蓋が閉じられた際に、前記凸起部と前記掛止部が遊びをもって掛合する様にすることもできる。又、本発明は、前記掛止部を、前記ガイド突起を挟んでヒンジ部側とその反対側に１対で設ける様にすることもできる。又、本発明は、前記ガイド突起を、前記ヒンジ部側からその反対側に向かって、徐々にその幅が狭くなる様に形成することもできる。 In the present invention, the separation piece has a top portion in which the protruding portion and the hole portion are formed, and the top portion is provided so as to be positioned at an eccentric position on the opposite side of the hinge portion of the cap. Can be. Further, according to the present invention, when the upper lid is closed, the protruding portion and the hooking portion can be engaged with each other with play. Further, according to the present invention, the latching portion may be provided in a pair on the hinge portion side and the opposite side with the guide protrusion interposed therebetween. In the present invention, the guide protrusion may be formed so that its width gradually decreases from the hinge portion side toward the opposite side.
本発明では、合成樹脂製キャップを開蓋する際に、分離片は蓋部に掛止されているため、上蓋の回動と共に分離片が引っ張ることができ、その力によって弱化部を破断することが可能であるため、手の力が弱い者であっても容易に開蓋することが可能である。 In the present invention, when the synthetic resin cap is opened, since the separation piece is hooked to the lid portion, the separation piece can be pulled with the rotation of the upper lid, and the weakened portion is broken by the force. Therefore, even a person with weak hand power can easily open the lid.
又、本発明では、蓋部と基部とを別体としたため、該蓋部を該基部の上方より取り付けることが可能となり、そのため、分離片を筒壁に掛止する際にその力を開口予定部の弱化部全体に略均等に掛けることができ、その際の該弱化部の破断を防止することができる。 Further, in the present invention, since the lid portion and the base portion are separated from each other, the lid portion can be attached from above the base portion, so that the force is expected to be opened when the separation piece is hooked on the cylindrical wall. The entire weakened portion of the portion can be applied substantially evenly, and the weakened portion can be prevented from being broken at that time.
本発明の第１実施形態を図１乃至図６に基づいて説明する。先ず、本実施形態の構成について説明する。合成樹脂製キャップ１（以下、単にキャップ１ともいう）は、蓋部２及び蓋部２に結合される中栓部３とを備えている。 A first embodiment of the present invention will be described with reference to FIGS. First, the configuration of the present embodiment will be described. A synthetic resin cap 1 (hereinafter also simply referred to as a cap 1) includes a lid portion 2 and an inner plug portion 3 coupled to the lid portion 2.
蓋部２は、上蓋４と、上蓋４とヒンジ部５を介して連結される基部６を有している。上蓋４は、天壁７と天壁７の外周縁より垂下するスカート壁８を有している。スカート壁８は、その一端がヒンジ部５と連続しており、他端には鍔部９が形成されている。又、スカート壁８の下端には係合突起１０が形成されている。天壁７の内面７ａにはインナーリング１１が垂設されている。インナーリング１１は、上蓋４が閉蓋された際に（以下、単に閉蓋ともいう）、注出筒１７の内面に当接し、シール性を確保できる様に形成される。 The lid 2 has an upper lid 4 and a base 6 connected to the upper lid 4 via a hinge portion 5. The upper lid 4 has a top wall 7 and a skirt wall 8 that hangs down from the outer peripheral edge of the top wall 7. One end of the skirt wall 8 is continuous with the hinge portion 5, and a flange portion 9 is formed at the other end. An engaging projection 10 is formed at the lower end of the skirt wall 8. An inner ring 11 is suspended from the inner surface 7 a of the top wall 7. The inner ring 11 is formed such that when the upper lid 4 is closed (hereinafter also simply referred to as “closed lid”), the inner ring 11 abuts against the inner surface of the dispensing cylinder 17 to ensure sealing performance.
インナーリング１１より内方の天壁内面７ａには掛止部１２が垂設されている。又、掛止部１２よりも更に内方の天壁内面７ａには、ガイド突起１３が設けられている。ガイド突起１３は、ヒンジ部３側から鍔部６側に向かって徐々に幅狭になるように、つまり、平面視略三角形状に形成される。本実施形態において、ガイド突起１３は、キャップ１の軽量化等の目的で中空になっているが、中空になっていないガイド突起１３も選択可能である。 A latching portion 12 is suspended from the inner surface 7a of the ceiling wall inward from the inner ring 11. A guide projection 13 is provided on the inner surface 7 a of the ceiling wall further inside than the latching portion 12. The guide protrusion 13 is formed so as to gradually become narrower from the hinge portion 3 side toward the flange portion 6 side, that is, in a substantially triangular shape in plan view. In the present embodiment, the guide protrusion 13 is hollow for the purpose of reducing the weight of the cap 1, but a guide protrusion 13 that is not hollow can also be selected.
掛止部１２は、その内面下端には掛止凸起１２ａが設けられており、好ましくは、ガイド突起１３を挟む様にヒンジ部３側及びその反対側、つまり、鍔部９側に１対として設けられる（以下、ヒンジ３部側の掛止部１２をヒンジ部側掛止部１２Ａと、鍔部９側の掛止部１２を鍔部側掛止部１２Ｂと呼称する）。本実施形態において、分離片２４の頂部２４ａをより偏心位置に設けるために、鍔部側掛止部１２Ｂは、ヒンジ部側掛止部１２Ａよりも幅狭に形成されているが、その大きさや形状等は必要に応じて適宜選択可能である。 The latching portion 12 is provided with a latching protrusion 12a at the lower end of the inner surface, and preferably a pair on the hinge portion 3 side and the opposite side thereof, that is, the flange portion 9 side so as to sandwich the guide projection 13. (Hereinafter, the latching part 12 on the hinge 3 part side is referred to as a hinge part side latching part 12A, and the latching part 12 on the collar part 9 side is referred to as a collar part side latching part 12B). In this embodiment, in order to provide the top part 24a of the separation piece 24 at a more eccentric position, the hook side latching part 12B is formed narrower than the hinge part side latching part 12A. The shape and the like can be appropriately selected as necessary.
基部６は、底壁１４と底壁１４の外周縁より垂下する嵌合筒１５とを有している。底壁１４の外周縁部には係止筒１６が立設されており、係止筒１６よりも内方の底壁１４には注出筒１７が立設される。注出筒１７より更に内方の底壁１４には、分離片２４が挿入可能に形成された挿入口部１８が形成されている。係止筒１６は、スカート部８の係合突起１０と係合可能に形成されており、上蓋４の閉蓋状態を保持するために設けられる。 The base 6 has a bottom wall 14 and a fitting cylinder 15 depending from the outer peripheral edge of the bottom wall 14. A locking cylinder 16 is erected on the outer peripheral edge of the bottom wall 14, and an extraction cylinder 17 is erected on the bottom wall 14 inward of the locking cylinder 16. An insertion port portion 18 in which a separation piece 24 can be inserted is formed in the bottom wall 14 further inside than the dispensing cylinder 17. The locking cylinder 16 is formed so as to be able to engage with the engagement protrusion 10 of the skirt portion 8 and is provided for maintaining the closed state of the upper lid 4.
中栓部３は、頂壁１９及び頂壁１９の外周縁から垂下する外筒２０を有している。頂壁１９の底面には内筒２１が垂設されており、外筒２０と内筒２１との間には容器本体（図示せず）の口部が嵌着される。外筒２０は、基部６の嵌合筒１５内に嵌合可能に形成されている。又、内筒２１よりも内方の頂壁１９には開口予定部２２が形成されている。 The inner plug portion 3 has a top wall 19 and an outer cylinder 20 that hangs down from the outer peripheral edge of the top wall 19. An inner cylinder 21 is suspended from the bottom surface of the top wall 19, and an opening of a container body (not shown) is fitted between the outer cylinder 20 and the inner cylinder 21. The outer cylinder 20 is formed so as to be fitted in the fitting cylinder 15 of the base 6. A planned opening 22 is formed on the top wall 19 on the inner side of the inner cylinder 21.
開口予定部２２は、弱化部２３により連結された分離片２４を有しており、本実施形態においては、平面視略菱形状をしているが、その形状・大きさ等は適宜選択可能である。分離片２４は、頂部２４ａ及び頂部２４ａより延在する裾部２４ｂを有している。頂部２４ａには、凸起部２５と孔部２６が形成されており、好ましくは、キャップ１の中心部Ｃよりも偏心した位置に設けられる。又、裾部２４ｂは、開口予定部２２の形状に合わせて形成される。尚、本実施形態では、キャップ１の軽量化等の目的で裾部２４ｂが中空となっているが、中空でない裾部２４ｂも選択可能である。 The planned opening portion 22 has a separation piece 24 connected by a weakening portion 23. In the present embodiment, the opening portion 22 has a substantially rhombus shape in plan view, but the shape and size thereof can be selected as appropriate. is there. The separation piece 24 has a top 24a and a skirt 24b extending from the top 24a. The top portion 24 a is formed with a protruding portion 25 and a hole portion 26, and is preferably provided at a position eccentric from the center portion C of the cap 1. Further, the skirt portion 24 b is formed in accordance with the shape of the planned opening portion 22. In the present embodiment, the skirt 24b is hollow for the purpose of reducing the weight of the cap 1, but a non-hollow skirt 24b can also be selected.
凸起部２５は、蓋部２と中栓部３とを結合した際に、掛止凸起１２ａと掛合、つまり、引っ掛かり合うことが可能に形成され、少なくともその際に掛止部１２と対向する位置に形成される。又、好ましくは、凸起部２５は、蓋部２と中栓部３とを結合した際に、掛止凸起１２ａとの間に遊びが生じる様に形成される。又、孔部２６は、蓋部２と中栓部３とを結合した際に、ガイド突起１３が挿入可能に形成される。 The projecting portion 25 is formed so as to be able to engage with, or be hooked with, the latching projection 12 a when the lid portion 2 and the inner plug portion 3 are coupled to each other, and at least at that time, it faces the latching portion 12. It is formed in the position to do. Preferably, the protruding portion 25 is formed so that play is generated between the protruding portion 12a and the hook portion 12a when the lid portion 2 and the inner plug portion 3 are coupled. The hole 26 is formed so that the guide protrusion 13 can be inserted when the lid 2 and the inner plug 3 are joined.
弱化部２３は、その肉厚が開蓋時に分離片２４が中栓部３から分離できる程度の厚さに形成され、好ましくは0.25 mm以下の厚さで形成される。この様にすることで、開封時に必要な力をより低減することが可能となる。 The weakened portion 23 is formed to a thickness that allows the separation piece 24 to be separated from the inner plug portion 3 when the lid is opened, and preferably has a thickness of 0.25 mm or less. By doing in this way, it becomes possible to reduce more force required at the time of opening.
蓋部２と中栓部３とは、同一の樹脂により成形してもよいが、各々を異なる樹脂で成形することも可能である。例えば、中栓部３をポリエチレン等の比較的可撓性が高い樹脂で成形し、蓋部２をポリプロピレン等の比較的可撓性が低く、耐熱性ある樹脂により成形することができる。この様にすることで、弱化部２３を容易に破断可能にしつつ、可撓性の高い樹脂の弱点である耐熱性を改善することが可能となる。又、掛止凸起１２ａの掛止力の確保もまた容易となる。 The lid portion 2 and the inner plug portion 3 may be molded from the same resin, but each may be molded from a different resin. For example, the inner plug portion 3 can be formed from a resin having a relatively high flexibility such as polyethylene, and the lid portion 2 can be formed from a resin having a relatively low flexibility such as polypropylene. By doing in this way, it becomes possible to improve the heat resistance which is a weak point of highly flexible resin, making the weakening part 23 easily fractureable. In addition, it is easy to secure the latching force of the latching protrusion 12a.
次に、本実施形態の製造方法について説明する。
（１）射出成形等の既存の成形手段によって、蓋部２及び中栓部３を別体として成形する。この際、上蓋４は開蓋させた状態で成形される。
Next, the manufacturing method of this embodiment is demonstrated.
(1) The lid portion 2 and the inner plug portion 3 are molded separately by existing molding means such as injection molding. At this time, the upper lid 4 is molded with the lid opened.
（２）上蓋４を閉蓋した後、打栓等の手段によって、蓋部２の嵌合筒１５に中栓部３の
外筒２０を嵌合することで、蓋部２と中栓部３とを結合（嵌着）させると共に分離片２４は、その凸起部２５が掛止部１２の掛止凸起１２ａに引掛けられ、分離片２４と掛止部１２とが掛合される。その際に、蓋部２のガイド突起１３が、分離片２４の孔部２６に挿入される様になっている。
(2) After the upper lid 4 is closed, the outer tube 20 of the inner plug portion 3 is fitted into the fitting tube 15 of the lid portion 2 by means such as plugging, whereby the lid portion 2 and the inner plug portion 3 Are connected (fitted) to each other, and the protruding portion 25 of the separating piece 24 is hooked on the hooking protrusion 12a of the hooking portion 12, and the separating piece 24 and the hooking portion 12 are hooked. At that time, the guide protrusion 13 of the lid portion 2 is inserted into the hole portion 26 of the separation piece 24.
この際、蓋部２は、上方より中栓部３に取り付けられることとなるため、その際の力（打栓力等）が弱化部２３全体に略均一に掛り、弱化部２３に局所的に掛ることを防止することが可能である。又、分離片２４は、ガイド突起１３によって位置決めされているため、凸起部２５と掛止凸起１２ａとが掛合する際に、分離片２４の位置がずれることを防止することができるので、より確実に弱化部２３の破断を防止することができる。尚、上記工程（２）は、中栓部３を容器本体に打栓等の手段によって取付けた後に行うことも可能である。 At this time, since the lid portion 2 is attached to the inner plug portion 3 from above, the force (plugging force, etc.) at that time is applied substantially uniformly to the entire weakened portion 23 and locally on the weakened portion 23. It is possible to prevent it from hanging. Further, since the separation piece 24 is positioned by the guide protrusion 13, it is possible to prevent the position of the separation piece 24 from shifting when the protruding portion 25 and the latching protrusion 12a are engaged with each other. Breakage of the weakened portion 23 can be prevented more reliably. In addition, the said process (2) can also be performed after attaching the inside stopper part 3 to a container main body by means, such as a stopper.
又、この際、掛止部１２が、一対のヒンジ部側掛止部１２Ａ及び鍔部側掛止部１２Ｂで構成されていることが好ましい。凸起部２５は、掛止凸起１２ａを乗り越える様に掛合されることとなるが、この様にすることで、蓋部２と中栓部３とを結合する際に、弱化部２３に掛る力を低減することが可能となり、より確実にその際の弱化部２３の破断を防止することが可能となる。 At this time, it is preferable that the latching portion 12 is composed of a pair of hinge-side latching portions 12A and a hook-side latching portion 12B. The protruding portion 25 is hooked so as to get over the latching protrusion 12a. By doing so, when the lid portion 2 and the inner plug portion 3 are coupled, the protruding portion 25 is hooked on the weakened portion 23. The force can be reduced, and the weakened portion 23 can be more reliably prevented from breaking at that time.
更に、本実施形態が打栓等の手段によって装着された容器（図示せず）の開封方法について説明する。上蓋４を、ヒンジ部５を支点として回動させると、掛止部１２の掛止凸起１２ａが分離片２４の凸起部２５が引っ掛るため、分離片２４は上蓋４の回動方向に引っ張り上げられ、その際に係る力によって弱化部２３が破断し、開口予定部２２は除去され、連通口２２Ａが形成されることで容器は開封される。 Furthermore, the opening method of the container (not shown) with which this embodiment was mounted | worn by means, such as a stopper, is demonstrated. When the upper lid 4 is rotated with the hinge portion 5 as a fulcrum, the latching projection 12a of the latching portion 12 is caught by the projection 25 of the separation piece 24, so that the separation piece 24 is in the pivoting direction of the upper lid 4. The weakened portion 23 is broken by the force applied at that time, the planned opening portion 22 is removed, and the communication port 22A is formed, whereby the container is opened.
この際、分離片２４の凸起部２５と掛止部１２の掛止凸起１２ａとの間に遊びがあることが好ましい。開蓋する際に、スカート部８の係合突起１０と係止筒１６との係合解除のタイミングと弱化部２３の破断のタイミングとをずらすことが可能となり、それらの力が合算されて掛ることを防止することが可能となる。従って、本実施形態は、開封の際に必要な力をより低減することが可能であり、より開封がし易いものとなっている。 At this time, it is preferable that there is play between the protruding portion 25 of the separating piece 24 and the hooking protrusion 12 a of the hooking portion 12. When the lid is opened, it is possible to shift the timing of disengagement between the engagement protrusion 10 of the skirt portion 8 and the locking cylinder 16 and the timing of breakage of the weakening portion 23, and these forces are added together. This can be prevented. Therefore, this embodiment can further reduce the force required for opening, and is easier to open.
又、この際に、分離片２４の頂部２４ａが鍔部９側の偏心位置にあることが好ましい。この様にすることで、開封の際にヒンジ部５を支点としてより大きな力を、分離片２４を介して弱化部２３に掛けることが可能となるため、より容易に開封することができるようになる。 At this time, it is preferable that the top 24a of the separation piece 24 is in an eccentric position on the flange 9 side. By doing in this way, it becomes possible to apply a greater force to the weakened portion 23 via the separation piece 24 when the hinge portion 5 is opened as a fulcrum, so that the opening can be performed more easily. Become.
以上、本発明を上記実施形態により説明したが、本発明は上記実施形態に限定されるものではなく、発明の要旨を変更しない範囲で適宜変更可能である。又、蓋部２と中栓部３とを螺合や接着等の他の方法によって結合することも可能である。 As mentioned above, although this invention was demonstrated by the said embodiment, this invention is not limited to the said embodiment, In the range which does not change the summary of invention, it can change suitably. Moreover, it is also possible to couple | bond the cover part 2 and the inside plug part 3 by other methods, such as screwing and adhesion | attachment.
