Description

本発明は、内容物の注出にしたがい充填空間の減容を可能としたブロー成形薄肉容器に関するもので、容器を開封する際の切断操作を安定して行ない、かつ、栓体を確実に切断することを可能とするものである。   The present invention relates to a blow-molded thin-walled container that enables the volume of the filling space to be reduced according to the content being dispensed, stably performing the cutting operation when opening the container, and reliably cutting the plug body. It is possible to do.

シャンプーやリンス、液体石鹸、化粧料等を入れる容器の分野では、資源の有効活用、ゴミの減量化を図る観点から薄肉の容器が多用されるようになってきている（例えば、特許文献１参照）。
特開2004−352328号公報 In the field of containers for shampoos, rinses, liquid soaps, cosmetics, etc., thin-walled containers are increasingly used from the viewpoint of effective use of resources and reduction of waste (for example, see Patent Document 1). ).
JP 2004-352328 A

従来のこの種の容器は、注出部に予めノッチや破断予定線が設けられており、容器胴体側を把持して栓体部分に捻りを加え、ノッチや破断予定線に沿って該栓体を切断、分離して開封していたが、容器の胴体は薄肉で変形し易いことから容器を開封する際に安定した切断作業が行ない難く、この点に関して未だ改良の余地が残されていた。   A conventional container of this type is provided with a notch and a planned break line in the pouring part in advance, grips the container body side, twists the plug body, and plugs the plug body along the notch and the planned break line. However, since the container body was thin and easily deformed, it was difficult to perform a stable cutting operation when the container was opened, and there was still room for improvement in this regard.

本発明の課題は、容器を開封する際に生じていた上記のような従来の不具合を解消できる新規なブロー成形薄肉容器を提案するところにある。   The subject of this invention exists in the place which proposes the novel blow molding thin wall container which can eliminate the above conventional malfunctions which arose when opening a container.

本発明は、内容物の注出に従って充填空間の減容を可能とする薄肉の胴体を備えたブロー成形薄肉容器であって、
前記胴体の上端角部に、前記充填空間につながる通路を有し破断予定線に沿う栓体の切断、分離にて該通路を開通させて充填空間内の内容物を排出する注出部を設け、
前記注出部の本体側に、該栓体の切断、分離に際して把持する第１の摘み部を配置し、前記栓体側に、第１の摘み部と同一線上にて延在し該第１の摘み部から離間する向きに引っ張ることによって該栓体を切断予定線に沿って切断、分離する第２の摘み部を配置してなり、前記第１の摘み部及び第２の摘み部は、周縁部のみ厚肉に形成されていると共に、前記第２の摘み部は、破断予定線につながる縁部を有し、前記第１の摘み部の縁部とこの縁部に隣接する第２の摘み部の縁部によって略Ｖ字状のノッチを形成することを特徴とするブロー成形薄肉容器である。 The present invention is a blow-molded thin-walled container provided with a thin-walled body that enables volume reduction of the filling space according to the contents being poured out,
At the upper end corner of the body, there is provided a pouring part that has a passage connected to the filling space and opens the passage by cutting and separating the plug body along the planned breaking line to discharge the contents in the filling space. ,
A first knob that is gripped when the plug body is cut and separated is disposed on the main body side of the pouring section, and extends on the same line as the first knob section on the plug body side. A second knob for cutting and separating the plug body along a planned cutting line by pulling it in a direction away from the knob is arranged, and the first knob and the second knob have a peripheral edge. Only the portion is formed thick , and the second knob has an edge connected to the planned fracture line, and the edge of the first knob and the second knob adjacent to the edge. A blow-molded thin-walled container characterized in that a substantially V-shaped notch is formed by the edge of the part .

上記の構成になるブロー成形薄肉容器においては、前記第１の摘み部と第２の摘み部とを破断予定線を通過して相互に連結する薄肉片を設けるのが好ましい。 In blow molding thin-walled container made to the above configuration, preferably provided with thin pieces connected to each other through a breakable line the first knob portion and the second knob portion.

第１の摘み部と第２の摘み部を把持してそれらを相互に離反させる向きに引っ張ることで栓体が注出部の本体側から切り離されることとなり、容器の開封に際して容器の胴体が変形することがなく、安定した切断操作が実現でき、かつ、確実な切断が可能となる。   By grasping the first knob part and the second knob part and pulling them away from each other, the plug body is separated from the main body side of the extraction part, and the container body is deformed when the container is opened. Therefore, a stable cutting operation can be realized and reliable cutting can be performed.

以下、図面を用いて本発明をより具体的に説明する。
図１は本発明に従うブロー成形薄肉容器（合成樹脂製）である。図における１は内容物の充填空間を区画形成する容器の胴体である。この胴体１は厚さが薄くなっており内容物の注出度合にしたがって充填空間を減容させることができるようになっている。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows a blow molded thin container (made of synthetic resin) according to the present invention. In the figure, reference numeral 1 denotes a body of a container that defines a filling space for contents. The body 1 has a small thickness so that the filling space can be reduced according to the degree of the content to be poured out.

また、２は胴体１の上端角部に設けられた注出部である。この注出部２は充填空間につながる通路2aを有しており、その先端には栓体2bが設けられている。３は切り込み等によって薄肉に形成された破断予定線、４は注出部２の容器胴体側に一体的に配置され栓体2bを切断、分離するに際して把持する第１の摘み部である。この第１の摘み部４はその縁部4aを肉厚とすることができ、該縁部4aの内側領域4bを薄肉とすることができ（周縁部、即ち、縁部4aのみが厚肉に形成される）、これにより指をあてがい易くする。 Reference numeral 2 denotes a pouring portion provided at the upper end corner of the body 1. The pouring part 2 has a passage 2a connected to the filling space, and a stopper 2b is provided at the tip thereof. Reference numeral 3 denotes a planned fracture line formed thinly by cutting or the like, and reference numeral 4 denotes a first knob part which is integrally disposed on the container body side of the pouring part 2 and is gripped when the stopper 2b is cut and separated. The edge 4a of the first knob 4 can be made thick, and the inner region 4b of the edge 4a can be made thin (only the peripheral edge , that is, the edge 4a is thick). This makes it easier to place a finger.

５は栓体2b側に一体的に配置された第２の摘み部である。第２の摘み部５は第１の摘み部４と同一線上にて延在し図２に示すように第１の摘み部４から離間する向きに引っ張ることによって該栓体2bを切断予定線３に沿って切断、分離するもので、その縁部5aは第１の摘み部４と同様に肉厚とし該縁部5aの内側領域5bを薄肉とすることができ（周縁部、即ち、縁部5aのみが厚肉に形成される）、とくに第２の摘み部５の縁部5a１を図３に示す如く破断予定線３まで延在させる（つなげる）ことにより栓体2bの切断、分離をより確実とすることが可能となる。 Reference numeral 5 denotes a second knob that is integrally disposed on the plug body 2b side. The second knob 5 extends on the same line as the first knob 4 and is pulled away from the first knob 4 as shown in FIG. The edge 5a can be made thick like the first knob 4 and the inner region 5b of the edge 5a can be made thin (periphery , ie, edge). 5a only is formed thicker), in particular the cutting of the second edge portion 5a 1 of the knob portion 5 extend until breakable line 3 as shown in FIG. 3 (connect) that the plug 2b, and separation It becomes possible to make it more reliable.

第１の摘み部４の縁部（破断予定線３側に位置する縁部）と、この縁部に隣接する第２の摘み部５の縁部のそれぞれにつき、下端から上端に向けて外開きになる傾斜を設け略Ｖ字状のノッチｎを形成することにより容器の開封作業を行ない易くする。   Each of the edge of the first knob 4 (the edge located on the planned fracture line 3 side) and the edge of the second knob 5 adjacent to this edge open outward from the lower end toward the upper end. The container is opened easily by forming a substantially V-shaped notch n.

また、第１の摘み部４と第２の摘み部５とを切断予定線３を通過して相互に連結する図４に示すような薄肉片６を設けることで商品の流通段階での栓体2bの不用意な切断、分離を回避し得る。   Moreover, the plug body in the distribution | circulation stage of goods is provided by providing the thin piece 6 as shown in FIG. 4 which connects the 1st knob | pick part 4 and the 2nd knob | pick part 5 through the cutting projected line 3, and mutually connects. Inadvertent cutting and separation of 2b can be avoided.

第１の摘み部４、第２の摘み部５の形状は適宜変更することが可能で、図示の例にのみ限定はされない。   The shape of the 1st knob | pick part 4 and the 2nd knob | pick part 5 can be changed suitably, and is not limited only to the example of illustration.

容器の接地面と破断予定線３とのなす角度θ（図１参照）は５〜90°、より好ましくは10〜60°とするのがよい。このような角度θに設定すると栓体2bを切断、分離しやすくなるだけでなく内容物が注ぎやすくなる。   The angle θ (see FIG. 1) formed by the ground contact surface of the container and the planned fracture line 3 is 5 to 90 °, more preferably 10 to 60 °. When the angle θ is set to such an angle, not only the plug 2b can be easily cut and separated but also the contents can be poured easily.

本発明の容器は合成樹脂にて構成することができる。成形法は従来公知のブロー成形法を適用して所望の形状に形成することが可能であり、図示の形状のみに限定されることはない。   The container of this invention can be comprised with a synthetic resin. The molding method can be formed into a desired shape by applying a conventionally known blow molding method, and is not limited to the illustrated shape.

本発明の容器に充填される内容物としては液状物、流動物、油脂含有物、界面活性剤を含む液剤、あるいは食品（例えば、ゼリー等の流動物やスープ等の液状物）等が挙げられる。   Examples of the contents filled in the container of the present invention include liquids, fluids, oils and fats, liquids containing surfactants, or foods (for example, fluids such as jelly and liquids such as soups). .

栓体を切断、分離して容器を開封する際の容器胴体の変形により生じる内容物のこぼれ等を防止し、安定した切断操作によって確実に栓体を切断することを可能としたブロー成形薄肉容器が提供できる。   Blow-molded thin-walled container that prevents the contents from spilling due to deformation of the container body when the container is cut and separated to open the container, and the stopper can be reliably cut by a stable cutting operation Can be provided.
