Description

本発明は、容器内の内容物をノズルを通して適量取り出すのに適したディスペンサーのノズルカバーに関するものであり、該ディスペンサーのノズルの注出開孔を確実に封止することによりその注出開孔近傍域で発生しがちな内容物の乾燥、固化に起因したノズル閉塞を確実に防止しようとするものである。   The present invention relates to a nozzle cover of a dispenser suitable for taking out an appropriate amount of the contents in a container through a nozzle, and in the vicinity of the dispensing opening by reliably sealing the dispensing opening of the nozzle of the dispenser. It is intended to reliably prevent nozzle clogging caused by drying and solidification of the contents that tend to occur in the area.

シャンプーやリンス、化粧水あるいは液体石鹸等を入れた据え置きタイプの容器には、押圧ヘッドを作動させることで容器内の内容物をノズルを通して適量注出するためディスペンサーが装着されている。   A stationary type container containing shampoo, rinse, lotion, liquid soap, or the like is equipped with a dispenser in order to dispense an appropriate amount of the contents in the container through a nozzle by operating a pressing head.

ところで、内容物として流動性があり、即乾性を有するものが充填されている容器にあっては、注出に係わる内容物がディスペンサーのノズルの注出開孔近傍域に付着、固化することがありノズル閉塞を引き起こす不具合がたびたび見られた。   By the way, in the case of a container filled with fluidity and quick-drying contents, the contents relating to the pouring may adhere and solidify in the vicinity of the pouring hole of the dispenser nozzle. There were frequent defects that caused nozzle clogging.

この点に関しては、前部を開口した有頂筒状とし、ステム両側面及び後面と、噴出ヘッド上面及び両側面及び後面とを被覆する基部下端縁を、装着キャップ上面中央部に突設した環状の係止突条外周に着脱自在に嵌合させるとともに、基部の前部開口縁より、ノズル筒上面及び両側面を被覆するノズル筒被覆部を延設してなるキャップ本体と、ノズル筒被覆部の頂板前縁に回動可能に上縁を連結するとともに、裏面より突設した嵌合筒をノズル筒先端に着脱可能に嵌合させた蓋板とを設けたキャップを備えた液体噴出器が提案されている（例えば、特許文献１参照）。
特開平１１−４３１６５号公報 In this regard, it is a ring-shaped tube with an open front, and a base lower end edge that covers both the side and rear surfaces of the stem, and the upper surface of the ejection head, both side surfaces, and the rear surface. A cap main body formed by extending a nozzle cylinder covering portion covering the nozzle cylinder upper surface and both side surfaces from the front opening edge of the base portion, and a nozzle main body covering portion A liquid ejector comprising a cap provided with a lid plate that is pivotably connected to the front edge of the top plate and is detachably fitted to the tip of the nozzle cylinder with a fitting cylinder protruding from the back surface. It has been proposed (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-43165

上記のような従来のキャップを備えた液体噴出器は、キャップの蓋板がノズル筒先端に嵌合するものであることから、内容物の乾燥、固化を抑制する点では著しい改善効果は見られたが、該蓋板は頂板前縁に回動可能に連結されているため、該蓋板に不用意な力が作用した場合にノズル筒先端における嵌合が簡単に解除されてしまうことが懸念され、また、これに加え、蓋板はキャップ本体とは基本的に同材質にて構成されていることから、選択される樹脂によっては、嵌合部位からの空気の侵入を確実に回避する点では未だ十分であるとは言えないのが現状であって、とくに、シール性のより一層の改善が求められていた。   The liquid ejector having the conventional cap as described above has a remarkable improvement effect in terms of suppressing the drying and solidification of the contents because the cap cover plate is fitted to the tip of the nozzle cylinder. However, since the lid plate is rotatably connected to the top edge of the top plate, there is a concern that the fitting at the tip of the nozzle cylinder may be easily released when an inadvertent force is applied to the lid plate. In addition, since the lid plate is basically made of the same material as the cap body, depending on the resin selected, it is possible to reliably avoid the intrusion of air from the fitting site. However, the current situation is not enough, and in particular, there has been a demand for further improvement in sealing performance.

本発明の課題は、ディスペンサーのノズル先端部の注出開孔を構造の複雑化を伴うことなしに確実に封止してノズル注出開孔近傍域での内容物の乾燥、固化を確実に防止できる新規なノズルカバーを提案するところにある。   The object of the present invention is to reliably seal the dispensing opening at the nozzle tip of the dispenser without complicating the structure, and to ensure that the contents are dried and solidified in the vicinity of the nozzle dispensing opening. A new nozzle cover that can be prevented is proposed.

以下、図面を用いて本発明をより具体的に説明する。
図１は合成樹脂製のノズルカバーの実施の形態をディスペンサーに装着した状態で示した断面図であり、図２はその外観を示した図である。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a cross-sectional view showing an embodiment of a synthetic resin nozzle cover mounted on a dispenser, and FIG. 2 is an external view thereof.

図における１は容器の口部に装着されたディスペンサーである。このディスペンサー１は押圧ヘッド１ａと、この押圧ヘッド１ａに設けられたノズル１ｂと、ディスペンサー１を容器の口部に固定保持するベースキャップ１ｃと、このベースキャップ１ｃを覆い隠す化粧カバー１ｄとを備えたポンプタイプのものを例として示してあり、押圧ヘッド１ａを押圧することで容器内の内容物をノズル１ｂを通して注出することができるようになっている。   In the figure, 1 is a dispenser attached to the mouth of the container. The dispenser 1 includes a pressing head 1a, a nozzle 1b provided on the pressing head 1a, a base cap 1c that fixes and holds the dispenser 1 on the mouth of the container, and a decorative cover 1d that covers the base cap 1c. The pump type is shown as an example, and the content in the container can be poured out through the nozzle 1b by pressing the pressing head 1a.

また、２はディスペンサー１に取り付けられノズル１ｂを格納、保護するためのノズルカバーである。このカバー２はディスペンサー１の少なくとも半周域をその頭部とともに取り囲んで後述の略Ｃ形状を呈する側壁部２ａ２の弾性変形力および化粧カバー１ｄの周壁に形成されたアンダーカットＣの如き係合手段にて着脱自在に係合保持される周壁２ａ（天面壁部２ａ１と側壁部２ａ２からなる）と、ノズル１ｂの先端に対面する行き止まり壁ｈを有し、該周壁２ａに連係する凹状空間Ｋを形成するとともにその空間Ｋ内にノズル１ｂを挿通、位置させて格納する格納壁部２ｂからなる。なお、図示の実施の形態では、格納壁部２ｂには行き止まり壁ｈ側に後述する軟質性シール部材の端部形状と合致する段部が形成されている。 Reference numeral 2 denotes a nozzle cover attached to the dispenser 1 for storing and protecting the nozzle 1b. The cover 2 surrounds at least a half-circumferential region of the dispenser 1 together with its head, and includes an elastic deformation force of a side wall portion 2a 2 having a substantially C shape, which will be described later, and an engagement means such as an undercut C formed on the peripheral wall of the decorative cover 1d. a freely peripheral wall 2a, which is engaged with and held (consisting covering panel portion 2a 1 and a side wall portion 2a 2) detachable at, have a dead end wall h facing the tip of the nozzle 1b, recessed space that links the peripheral wall 2a The storage wall portion 2b is formed to store the nozzle 1b in the space K. In the illustrated embodiment, the storage wall portion 2b is formed with a step portion matching the end shape of the soft seal member described later on the dead end wall h side.

３は格納壁部２ｂの凹状空間Ｋ内でその開放方向先端または周壁が、格納壁部２ｂの周壁に形成された環状または間欠状のアンダーカットＤの如き係合手段にて嵌合保持される軟質性シール部材である。軟質性シール部材３は、ノズルカバー２を取り付けるとき、ノズル１ｂの先端部が凹部３ａにて嵌合してその注出開孔を確実に封止する。   3 is fitted and held in the concave space K of the storage wall 2b by an engagement means such as an annular or intermittent undercut D formed on the peripheral wall of the storage wall 2b. It is a soft seal member. When the nozzle cover 2 is attached to the soft seal member 3, the tip end portion of the nozzle 1b is fitted in the recess 3a to securely seal the dispensing opening.

上記の構成になるノズルカバー２は図２のＡ−Ａ断面を図３に示すように、ディスペンサーの側面を取り囲む側壁部２ａ２が略Ｃ形状を呈しており、水平方向(図中Ｘ)に沿う差込みと引き抜きにより該側壁部２ａ２を弾性変位させてノズルカバー２の着脱を行う（カバーの着脱に際して押圧ヘッド１ａを押してしまうおそれがない）。なお、前述のアンダーカットＣ（化粧カバー１ｄ周壁に形成したもの）は、ノズルカバー２の上方への不用意な変位を防止するもので、ノズルカバー２の格納壁部２ｂに固定保持された軟質性シール部材３によるノズル１ｂの先端部の安定した嵌合を補助している。 The nozzle cover 2 having the above-described configuration has a substantially C-shaped side wall 2a 2 surrounding the side surface of the dispenser as shown in FIG. The side wall 2a 2 is elastically displaced by insertion and extraction along the axis, and the nozzle cover 2 is attached / detached (there is no possibility of pressing the pressing head 1a when attaching / detaching the cover). The undercut C described above (formed on the peripheral wall of the decorative cover 1d) prevents inadvertent displacement upward of the nozzle cover 2, and is a soft material fixedly held on the storage wall 2b of the nozzle cover 2. The stable fitting of the tip end portion of the nozzle 1b by the conductive seal member 3 is assisted.

図４〜６は本発明に従うノズルカバー２の実施の形態を示したものである。この例は、ノズルカバー２の側壁部２ａ２の各伸延末端部の少なくとも一箇所にそれぞれ、ディスペンサー１に連係させてノズルカバー２を係止する、ノズル１ｂに向けて内向きに折返した爪部４を設ける一方で、軟質性シール部材３に平坦面３ｂを形成して、この平坦面３ｂをノズル１ｂの先端部に押し当てる構造のものである。 4 to 6 show an embodiment of the nozzle cover 2 according to the present invention. In this example, the claw portion 4 folded inward toward the nozzle 1b is engaged with the dispenser 1 to lock the nozzle cover 2 at least at one location of each extended end portion of the side wall portion 2a2 of the nozzle cover 2. On the other hand, a flat surface 3b is formed on the soft seal member 3, and the flat surface 3b is pressed against the tip of the nozzle 1b.

この構成のノズルカバー１は軟質性シール部材３との接触部が平坦面３ｂであり、ただ単に軟質性シール部材３を接触させただけではノズル１ｂの注出開孔を確実に封止することはできないが、ノズルカバー２をディスペンサー１に取り付けるべく、ノズル１ｂに向けて内向きに折返した爪部４をディスペンサー１に連係させて、軟質性シール部材３をノズル１ｂの先端部に強く押し付けることでノズル１ｂの注出開孔を確実に封止する。 The nozzle cover 1 having this structure has a flat surface 3b in contact with the soft seal member 3, and the discharge opening of the nozzle 1b can be reliably sealed simply by contacting the soft seal member 3. In order to attach the nozzle cover 2 to the dispenser 1, the claw portion 4 folded inward toward the nozzle 1b is linked to the dispenser 1 and the soft seal member 3 is strongly pressed against the tip of the nozzle 1b. Thus, the dispensing hole of the nozzle 1b is securely sealed.

この例のノズルカバー２も図６に図５のＢ−Ｂ断面を示すように側壁部２ａ２が略Ｃ形状を呈するもので、水平方向に沿う差込みと引き抜きにより該側壁部２ａ２を弾性変位させてノズルカバー２の着脱を行う。なお、図示の例では、前述の如く、爪部４をディスペンサー１に連係させるためディスペンサー１の押圧ヘッド１ａの周壁に形成された溝部に係合させる構造を示した（図６参照）が、本発明はこれに限るものではなく、例えば押圧ヘッド１ａに突起又は縦突条を設けノズルカバー２の装着の際、爪部４が同箇所を乗り越えて係合させる構成を採用してもよい。 The nozzle cover 2 of this example also has a substantially C-shaped side wall 2a 2 as shown in FIG. 6 which shows a cross section BB of FIG. 5, and the side wall 2a 2 is elastically displaced by insertion and withdrawal along the horizontal direction. The nozzle cover 2 is attached and detached. In the illustrated example, as described above, the structure in which the claw portion 4 is engaged with the groove portion formed in the peripheral wall of the pressing head 1a of the dispenser 1 to link the dispenser 1 is shown (see FIG. 6). The invention is not limited to this. For example, a configuration in which a protrusion or a vertical protrusion is provided on the pressing head 1a and the claw portion 4 climbs over and engages with the nozzle cover 2 may be employed.

なお、本発明の実施の形態では、側壁部２ａ２を弾性変位させてノズルカバー２の着脱を行うものを例として示したが、天面壁部２ａ１を弾性変位させてノズルカバー２の着脱を行うようにしてもよく、この点については限定されない。 In the embodiment of the present invention, the side wall 2a 2 is elastically displaced and the nozzle cover 2 is attached / detached as an example. However, the top wall 2a 1 is elastically displaced and the nozzle cover 2 is attached / detached. However, this point is not limited.

軟質性シール部材３は、ブチルゴムやシリコンゴム、エラストマー、発泡ポリエチレン、パッキン等を適用することが可能である。また、ノズルカバー２と同系の材質（例えば、軟質性シール部材３としてオレフィン系のエラストマー樹脂を使用し、ノズルカバー２をオレフィン系の樹脂にて構成する）のものを使用するのが好ましく、これにより例えば、軟質性シール部材３をノズルカバー２に対してインサート成形した場合に相互に融着することが可能となり、該軟質性シール部材３の格納壁部２ｂに対する固定をより強固とすることができる。   As the soft seal member 3, butyl rubber, silicon rubber, elastomer, foamed polyethylene, packing, or the like can be applied. In addition, it is preferable to use a material similar to the nozzle cover 2 (for example, an olefin elastomer resin is used as the soft seal member 3 and the nozzle cover 2 is made of an olefin resin). Thus, for example, when the soft seal member 3 is insert-molded with respect to the nozzle cover 2, it becomes possible to fuse the soft seal member 3 to the storage wall portion 2b. it can.

着脱が簡単で、ノズルの注出開孔を確実に封止できるノズルカバーが提供できる。   It is possible to provide a nozzle cover that is easy to attach and detach and can reliably seal the nozzle opening.
