Description

本発明は、押出しブロー成形による容器の口筒部の形状に関するものである。   The present invention relates to the shape of a mouth tube portion of a container by extrusion blow molding.

図3は押出しブロー成形法の概略を示した説明図であり、押出機Eで、溶融状態の樹脂をダイスDを介して押出し、円筒状のパリソンPを成形し、このパリソンPをブロー成形用の割金型Mで挟んで、下端部をピンチオフ部Poでシールした状態でエアブローして容器を成形する。
この際、ブロー成形と同時に容器の口筒部を形成する方法の中に、たとえば特許文献1の図5に示されるUPI(アッパープラグイン)と一般的に呼ばれる方法がある。
FIG. 3 is an explanatory view showing an outline of the extrusion blow molding method. In the extruder E, a molten resin is extruded through a die D to form a cylindrical parison P, and this parison P is used for blow molding. The container is molded by air blowing with the lower end portion sealed by the pinch-off portion Po.
At this time, among methods for forming the mouth tube portion of the container simultaneously with blow molding, for example, there is a method generally called UPI (upper plug-in) shown in FIG.

この方法は、図4に示すように、割金型Mに挟持されるパリソンPの上方からプラグPLを押し込んで、この割金型MとプラグPLとにより構成される喰切り部Cにより、口筒部102の上端面上方の不要部分であるバリBを切断除去するものであり、このUPI法によれば、後工程でバリを取り除く必要が無く、製造コストを低減することができる。
特開2001−384130号公報
As shown in FIG. 4, this method is such that a plug PL is pushed in from above the parison P sandwiched between the split molds M, and the mouthpiece C formed by the split mold M and the plug PL The burr B, which is an unnecessary portion above the upper end surface of the cylindrical portion 102, is cut and removed. According to this UPI method, it is not necessary to remove the burr in a subsequent process, and the manufacturing cost can be reduced.
JP 2001-384130 A

しかし、このUPI法によると、口筒部の上端面外周縁のバリを切断した部分に鋭利な切断痕が形成される場合がある。口筒部に中栓やポンプを嵌合して使用する場合はよいが、そのまま使用する場合にはこの鋭利な切断痕により、指先や、唇を傷つける恐れがある。   However, according to this UPI method, a sharp cutting trace may be formed in the part which cut | disconnected the burr | flash of the upper end surface outer periphery of a mouth_tube | cylinder part. Although it is good to use an inner plug or pump fitted to the mouth tube part, there is a risk of damaging the fingertip or lips due to this sharp cutting trace when used as it is.

本発明は、上記した従来技術における問題点を解消すべく創案されたものであり、口筒部の上端面に形成されるUPI法による切断痕への指先等の接触を口筒部の形状により抑制することを技術的課題とするものであり、もって安全で、安心して使用できる合成樹脂製容器を低コストで提供することを目的とする。   The present invention has been devised to solve the above-described problems in the prior art, and the contact of a fingertip or the like to the cut trace by the UPI method formed on the upper end surface of the mouth tube portion depends on the shape of the mouth tube portion. It is a technical problem to suppress, and an object is to provide a low-cost synthetic resin container that is safe and can be used with confidence.

上記技術的課題を解決する本発明の内、請求項1記載の発明の手段は、
押出しブロー成形による容器の口筒部において、
この口筒部の上端面を、上端面の内側周部に比較して外側周部を段差状に下位に位置させた形状とすること、
ブロー成形時に、ブロー成形用の割金型に挟持されるパリソンの上方からプラグを押し込んで、内側周部の外周縁部分で、この割金型とプラグにより構成される喰切り部により口筒部の上端面上方の不要部分切断除去されていること、
内側周部と外側周部の段差の平均値を、前記切断除去による内側周部の外周縁部分に形成される切断痕による指先の切傷の防止が可能に1mm以下に設定すること、にある。
Among the present invention for solving the above technical problems, the means of the invention according to claim 1 is:
In the mouth tube part of the container by extrusion blow molding,
The upper end surface of the mouth tube portion is made to have a shape in which the outer peripheral portion is positioned at a lower level in a step shape compared to the inner peripheral portion of the upper end surface,
At the time of blow molding, the plug is pushed in from the upper part of the parison sandwiched between the blow mold split molds, and the mouthpiece part is formed by the cutting part constituted by the split mold and the plug at the outer peripheral edge portion of the inner peripheral part. the upper end above the surface of the unnecessary portion of is cut and removed,
The average value of the level difference between the inner peripheral portion and the outer peripheral portion is set to 1 mm or less so that the fingertip can be prevented from being cut by a cut mark formed on the outer peripheral edge portion of the inner peripheral portion by the cutting and removal.

ここで、上記請求項1中に記載される、「ブロー成形用の割金型に挟持されるパリソンの上方からプラグを押し込んで、割金型とプラグにより構成される喰切り部により口筒部上端の不要部分を切断除去する」と云う方法を、以下、UPI法と略記する。
そして、請求項1記載の上記構成の基本的な考え方は、UPI法によるバリの切断痕を、指先等が最も触れ易くかつ切傷し易いエッジ部である口筒部の上端面外周縁位置から内周縁方向に近づけた位置に形成するようにして、この切断痕による指先等の切傷をなくすことにある。
Here, as described in the above-mentioned claim 1, "the plug portion is pushed in from above the parison sandwiched between the blow mold split molds, and the mouthpiece portion is formed by the cut-off section constituted by the split mold and the plugs. The method of “cutting and removing the unnecessary portion at the upper end” is hereinafter abbreviated as the UPI method.
The basic concept of the above-described configuration according to claim 1 is that the burr cutting trace by the UPI method is applied from the position of the outer peripheral edge of the upper end surface of the mouth tube portion, which is the edge portion most easily touched by the fingertip and the like. It is to be formed at a position close to the peripheral direction so as to eliminate cuts such as fingertips due to the cut marks.

すなわち、請求項1記載の上記構成により、口筒部の上端面の形状を、内側周部に比較して外側周部を段差状に下位に位置させた形状とすることにより、UPI法において、割金型とプラグにより構成される喰切り部をこの段差部分を利用するように配設することにより、バリの切断痕の形成位置を口筒部の内側周部の外周縁部分、すなわち口筒部の上端面外周縁から内周縁方向に近づけて位置させることができる。   That is, according to the above-described configuration of claim 1, the shape of the upper end surface of the mouth tube portion is a shape in which the outer peripheral portion is positioned in a lower step as compared with the inner peripheral portion. By arranging the cut-off portion constituted by the split mold and the plug so as to use this stepped portion, the formation position of the burr cutting trace is set to the outer peripheral edge portion of the inner peripheral portion of the mouthpiece portion, that is, the mouthpiece It can be located closer to the inner peripheral edge direction from the outer peripheral edge of the upper end surface of the part.

ここで、外側周部を段差状に僅かに下位に位置させることにより、この外側周部部分のブロック状の機能が発揮され、切断痕に指先等が直接触れ難くすることができ、たとえ触れたとしても段差が低いので切断痕が指先等に大きく食込むこともないので、切断痕による切傷を防ぐことができる。   Here, by placing the outer peripheral portion slightly lower in a step shape, the block-like function of this outer peripheral portion is exhibited, and it is possible to make it difficult for the fingertips or the like to touch the cutting trace directly, even if touched. However, since the level difference is low, the cutting trace does not bite into the fingertip or the like, so that the cut by the cutting trace can be prevented.

ここで、内側周部と外側周部の段差が高くなると、切断痕を内周縁方向に近づけて位置させた場合にも、指先が切断痕に直接接触し、指先等に深く食込む恐れがあるので、この段差は、割金型とプラグにより構成される喰切り部の喰切り性、耐久性等が損なわれない範囲で、できるだけ低くするのが好ましい。   Here, when the level difference between the inner peripheral portion and the outer peripheral portion becomes high, even when the cutting trace is positioned close to the inner peripheral edge, the fingertip may directly contact the cutting trace and deeply bite into the fingertip or the like. Therefore, it is preferable to make this step as low as possible within a range that does not impair the cutting ability, durability, and the like of the cutting portion constituted by the split mold and the plug.

ここで上記したように、段差は割金型とプラグにより構成される喰切り部の喰切り性、耐久性等が損なわれない範囲で、できるだけ低くするのが好ましいが、内側周部と外側周部の段差の平均値を1mm以下とすることにより、口筒部上端面の外側周部部分のブロック状の機能が十分に発揮され、切断痕による指先等の切傷を確実に防ぐことができる。
なお、割金型の型開きを容易にするために、通常外側周部は外周縁方向に斜め下方に若干傾斜させて成形するため、平均値で段差の設計基準を示している。
Here, as described above, the step is喰切-resistant of喰切Ri portion constituted by split mold and plug, to the extent that durability is not compromised, but preferably as low as possible, the inner side peripheral portion and the outer By setting the average value of the step of the peripheral portion to 1 mm or less, the block-like function of the outer peripheral portion of the upper end surface of the mouth tube portion is sufficiently exhibited, and it is possible to reliably prevent cuts such as fingertips due to cutting marks. .
In order to facilitate the mold opening of the split mold, usually the outer peripheral portion for molding by slightly inclined obliquely downwardly in the outer periphery direction, it shows a stepped design criteria in average value.

本発明は、上記した構成となっているので、以下に示す効果を奏する。
請求項1記載の発明にあっては、UPI法で口筒部を形成するにおいて、喰切り部によって形成されるバリの切断痕の形成位置を、口筒部の上端面外周縁の角部から内周縁方向に近づけて、さらに外側周部を段差状に僅かに下位に位置させることにより、この外側周部部分のブロック状の機能が発揮され、切断痕による指先等の切傷を防ぐことができる。
Since the present invention has the above-described configuration, the following effects can be obtained.
In the invention of claim 1, when forming the mouth tube portion by the UPI method, the formation position of the cutting mark of the burr formed by the biting portion is determined from the corner portion of the outer peripheral edge of the upper end surface of the mouth tube portion. By approaching the inner peripheral direction and further positioning the outer peripheral portion slightly lower in a step shape, the block-like function of this outer peripheral portion is exhibited, and it is possible to prevent cuts such as fingertips due to cutting marks. .

そして、内側周部と外側周部の段差の平均値を1mm以下とすることにより、口筒部上端面の外側周部部分がブロック状の機能が十分に発揮され、切断痕による指先等の切傷を確実に防ぐことができる。



Then, by the average value of the step on the inner side peripheral portion and the outer peripheral portion and 1mm or less, the outer peripheral portion of the mouth tube portion upper face of the block-shaped function is fully exhibited, such as the fingertip by the cutting marks Cuts can be reliably prevented.



以下、本発明を実施例に沿って、図面を参照しながら説明する。
図1は本発明の口筒部2の一実施例を示す縦断面図であり、この口筒部2は円筒状であり、外周面に螺条を形成している。
Hereinafter, the present invention will be described according to embodiments with reference to the drawings.
FIG. 1 is a longitudinal sectional view showing an embodiment of the mouth tube portion 2 of the present invention. The mouth tube portion 2 is cylindrical and has a thread on the outer peripheral surface.

この口筒部2の上端面は段差状に形成されており、内側周部3に比較して外側周部4は僅かに下位に位置している。この外側周部4は外周縁方向に斜め下方に若干傾斜しているが、内側周部3と外側周部4の段差hの平均値は0.5mmである。また、内側周部3の外周縁にUPI法によるバリBの切断痕6が形成されている。   The upper end surface of the mouth tube portion 2 is formed in a step shape, and the outer peripheral portion 4 is positioned slightly lower than the inner peripheral portion 3. The outer peripheral portion 4 is slightly inclined obliquely downward in the outer peripheral direction, but the average value of the level difference h between the inner peripheral portion 3 and the outer peripheral portion 4 is 0.5 mm. Further, burr B cut marks 6 are formed on the outer peripheral edge of the inner peripheral portion 3 by the UPI method.

ここで、上記のように口筒部2の上端面に段差を設けることにより、切断痕6の形成位置を口筒部2の上端面の外周縁から、内周縁方向に寄った位置にすることができ、段差hを本実施例の0.5mmと1mm以下に、十分低くしておけば、たとえ指先が口筒部2上端面の外周縁部分に接触したとしても(図1中の二点鎖線で表した指先Fを参照)、外側周部4部分がブロック状の機能を発揮し、切断痕6で指先を傷つけることはない。   Here, by providing a step on the upper end surface of the mouthpiece part 2 as described above, the formation position of the cut mark 6 is made a position closer to the inner periphery direction from the outer periphery of the upper end face of the mouthpiece part 2. If the step h is sufficiently low to 0.5 mm and 1 mm or less in the present embodiment, even if the fingertip contacts the outer peripheral edge portion of the upper end surface of the mouth tube portion 2 (two points in FIG. 1). The fingertip F represented by a chain line is referred to), and the outer peripheral portion 4 portion exhibits a block-like function, and the fingertip is not damaged by the cut marks 6.

ここで、口筒部2の上端面の上方から指先を接触しようとした場合には、この指先が切断痕6に直接触れることもあるが、この切断痕の先端の鋭利な部分には斜めに接触し、さらに段差hを本実施例のように十分低くしておけば、切断痕6の指先への食込みは限定されたものとなるので、切傷するまでには至らない。   Here, when a fingertip is to be contacted from above the upper end surface of the mouth tube portion 2, the fingertip may directly touch the cutting trace 6, but the diagonal portion at the tip of the cutting trace is inclined. If contact is made and the level difference h is made sufficiently low as in the present embodiment, the biting of the cut marks 6 into the fingertips is limited, so that the cut does not occur.

図2は図1に示す口筒部2を形成するためのUPI法に係る概略説明図である。ブロー成形用の割金型Mに挟持されるパリソンPの上方開口部からプラグPLを押し込んで口筒部2の上端面上方の不要部分であるバリBを切断除去する際に、この金型MとプラグPLにより構成される喰切り部Cを図2に示されるように段差状にすることにより、バリBの喰切り部分を口筒部2上端面の内側周部3の外周縁とすることができ、図1に示すようにバリBの切断痕6の形成位置を内側周部3の外周縁とすることができる。
また、本実施例のように外側周部4を外周縁方向に斜め下方に若干傾斜した形状とすることにより、ブロー成形後の型抜きを容易に達成することができる。
FIG. 2 is a schematic explanatory diagram relating to the UPI method for forming the mouth tube portion 2 shown in FIG. When the plug PL is pushed from the upper opening of the parison P sandwiched by the blow molding split mold M to cut and remove the burrs B which are unnecessary portions above the upper end surface of the mouth tube section 2, this mold M The cut-off portion C constituted by the plug PL is formed in a step shape as shown in FIG. 2, so that the cut-off portion of the burr B is set as the outer peripheral edge of the inner peripheral portion 3 of the upper end surface of the mouth tube portion 2. As shown in FIG. 1, the formation position of the cut mark 6 of the burr B can be set as the outer peripheral edge of the inner peripheral portion 3.
Moreover, the die-cutting after blow molding can be easily achieved by making the outer peripheral part 4 into the shape slightly inclined diagonally downward in the outer peripheral direction as in this embodiment.

なお、図4に示される従来の喰切り部Cでは、口筒部102上端面の外周縁に切断痕が形成される。   In the conventional cut-off portion C shown in FIG. 4, a cut mark is formed on the outer peripheral edge of the upper end surface of the mouth tube portion 102.

以上、実施例に沿って本願発明の実施形態とその作用効果について説明したが、本願発明はこの実施例に限定されるものではない。たとえば、本実施例のように螺条を形成した口筒部に限定されるものではないし、また単層の容器であっても多層の容器であってもよい。   As mentioned above, although embodiment of this invention and its effect were demonstrated along the Example, this invention is not limited to this Example. For example, it is not limited to the mouth tube portion in which the thread is formed as in this embodiment, and may be a single layer container or a multilayer container.

以上説明したように、本発明の押出しブロー成形による容器の口筒部は上端面に形成されるUPI法による切断痕への指先等の直接的な接触を抑制するものであり、安全で安心して使用できる合成樹脂製容器を低コストで提供でき、幅広い展開が期待される。   As described above, the mouth tube portion of the container by extrusion blow molding of the present invention suppresses direct contact of fingertips and the like to the cut mark by the UPI method formed on the upper end surface, and is safe and secure. We can provide usable synthetic resin containers at low cost, and a wide range of development is expected.
