Description

本発明はノズルカバーに関し、詳しくは、ノズルを先端に突設した噴出ヘッドを備えたディスペンサーに装着するノズルカバーに関する。   The present invention relates to a nozzle cover, and more particularly, to a nozzle cover that is attached to a dispenser that includes an ejection head having a nozzle projecting from its tip.

ディスペンサーとして、容器体上部に嵌着した装着キャップ中央を貫通したステムを介して上方付勢状態で上下動可能に突出した噴出ヘッドを押し下げることにより、容器体内液が噴出ヘッドの前部から突出したノズルより噴出する如く構成したものが知られている。この種のディスペンサーではノズル内に残存した液が乾燥，固化するという不都合が生じる場合がある。   As a dispenser, the fluid in the container protrudes from the front part of the ejection head by pushing down the ejection head that protrudes upward and downward in a biased state through a stem penetrating the center of the mounting cap fitted to the upper part of the container body What was comprised so that it might eject from a nozzle is known. In this type of dispenser, there may be a problem that the liquid remaining in the nozzle is dried and solidified.

ノズル内の液が固化すると液通路が狭くなり、また、通路の塞ぎ方によっては液が前方へ勢い良く噴出するという不都合が生じる。この様な場合、吐出方向が決まらず思わぬ方向へ噴出するような不具合を生じる虞れがある。   When the liquid in the nozzle is solidified, the liquid passage is narrowed, and depending on how the passage is closed, there is a disadvantage that the liquid is ejected vigorously forward. In such a case, there is a possibility of causing a problem that the ejection direction is not determined and the ink is ejected in an unexpected direction.

この様な点を考慮して、ノズル内の液の乾燥を防止し、簡単に着脱することができるキャップを備えたディスペンサーが提案されている。（例えば特許文献１参照）   In view of these points, a dispenser having a cap that prevents the liquid in the nozzle from drying and can be easily attached and detached has been proposed. (For example, see Patent Document 1)

特許文献１のディスペンサーは、前部を開口した有頂筒状で、且つ、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板下端縁を、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、ノズル上面及び両側面を被覆するノズル被覆部を延設してなるキャップ本体と、ノズル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先端に着脱可能に嵌合させた蓋板と、からなるキャップを設けている。
特開平１１−４３１６５号公報 The dispenser disclosed in Patent Document 1 has a cylindrical shape with an opening at the front, and the bottom edge of the substrate that covers both the side and rear surfaces of the stem, the upper surface of the ejection head, the both sides, and the rear surface projects into the center of the upper surface of the mounting cap. A cap body formed by extending a nozzle covering portion covering the nozzle upper surface and both side surfaces from the front opening edge of the base portion, and a nozzle covering portion that is detachably fitted to the outer periphery of the provided annular locking protrusion. A top plate is connected to the top edge of the top plate so as to be rotatable, and a cap plate is provided that includes a fitting plate protruding from the back surface and detachably fitted to the tip of the nozzle.
JP 11-43165 A

特許文献１のディスペンサーは、キャップの存在でノズル内の液の乾燥を防止でき、ノズル内の液の固化を防止することができる優れたものである。しかしながら、このディスペンサーは使用に当たりキャップを外す必要があり、また、使用後には再びキャップを装着しておかなければならないという使用上の不便がある。   The dispenser of Patent Document 1 is excellent in that the presence of a cap can prevent the liquid in the nozzle from drying, and the liquid in the nozzle can be prevented from solidifying. However, this dispenser requires the cap to be removed before use, and there is an inconvenience in use that the cap must be mounted again after use.

本発明は上記した点に鑑みてなされたもので、このタイプの既存のディスペンサーに装着して使用することができ、ノズル内の液の固化が生じた場合にも液が前方へ勢い良く飛び出すという不都合を確実に防止でき、しかも一旦装着すれば洗浄等の特殊事情がない限り取り外す必要がなく、取り扱いが便利なノズルカバーを提案する。また、構造が簡単で安価に製造できるノズルカバーを提案する。更に加えて、ノズル内の固化を併せて防止できるノズルカバーを提案する。また、簡単に取り外せて洗浄が容易であり、また、装着も容易なノズルカバーを提案する。   The present invention has been made in view of the above points, and can be used by being mounted on an existing dispenser of this type, and even when the liquid in the nozzle is solidified, the liquid jumps forward vigorously. We propose a nozzle cover that can reliably prevent inconveniences, and that is easy to handle once it is installed, without having to be removed unless there are special circumstances such as cleaning. We also propose a nozzle cover that has a simple structure and can be manufactured at low cost. In addition, a nozzle cover that can prevent solidification in the nozzle is also proposed. In addition, a nozzle cover that can be easily removed and easily cleaned and is easy to install is proposed.

本発明のノズルカバーはディスペンサーに装着して使用される。   The nozzle cover of the present invention is used by being mounted on a dispenser.

ノズルカバーを装着するディスペンサーは、ノズルを前方へ突設した噴出ヘッドを備えているものであれば良い。この種のディスペンサーとして、例えば、容器体上部に嵌着した装着キャップ中央を貫通して上方付勢状態で押し下げ可能にステムを突出し、ステムの上端にノズル付噴出ヘッドを嵌着し、噴出ヘッドを押し下げることにより、容器体内の液をノズルより噴出する如き内臓ポンプ機構を備えているものが挙げられる。また、ノズルは、噴出ヘッドより水平に真っ直ぐ前方へ延びるタイプ，或いは全体的に前方へ傾斜上昇するタイプ等が挙げられ、それに加えてそれぞれ先端部が若干下方へ傾斜下降するタイプ等が挙げられる。いずれにしろこれらのディスペンサーは既存のものを採用できる。   The dispenser to which the nozzle cover is attached may be any one provided with an ejection head having a nozzle projecting forward. As this type of dispenser, for example, the stem protrudes through the center of the mounting cap fitted to the upper part of the container body and can be pushed down in an upward biased state, and the ejection head with a nozzle is fitted to the upper end of the stem. One having a built-in pump mechanism that ejects the liquid in the container body from a nozzle by pushing down is exemplified. In addition, the nozzle includes a type that extends straight forward from the ejection head, a type that tilts upward as a whole, and a type in which the tip portion tilts and descends slightly downward. In any case, these dispensers can adopt existing ones.

ノズルカバーは合成樹脂或いはエラストマーで形成され、筒部と、本体部とから構成されている。合成樹脂としては、例えば、ポリエチレン，ポリプロピレン等のポリオレフィン系樹脂，ポリエチレンテレフタレート等のポリエステル樹脂等が挙げられ、また、エラストマーとしては、シリコーンゴム等のゴム類が挙げられるが当然これらに限られるものではない。   The nozzle cover is formed of a synthetic resin or an elastomer, and includes a cylindrical portion and a main body portion. Examples of synthetic resins include polyolefin resins such as polyethylene and polypropylene, polyester resins such as polyethylene terephthalate, and examples of elastomers include rubbers such as silicone rubber, but of course not limited thereto. Absent.

筒部は、ノズル先端部外周に一端を嵌着するとともに、他端を下方へ向けて開口する形態をなしている。ディスペンサーのノズルは上記した如き種々のタイプが存在するが、そられの全てに対応させて上記要件を満たすべき筒部を形成する。即ち、下端を下方に向けて開口すべくノズルのタイプにより筒部の形態を変化させ、必要に応じて湾曲或いは屈曲させた形態のものを採用する。   The tube portion has a form in which one end is fitted to the outer periphery of the nozzle tip portion and the other end is opened downward. There are various types of nozzles of the dispenser as described above, and a cylinder portion that satisfies the above requirements is formed corresponding to all of the nozzles. That is, a configuration in which the shape of the cylindrical portion is changed depending on the type of the nozzle so as to open the lower end downward, and a shape that is curved or bent as necessary is adopted.

ノズルカバーを合成樹脂により形成する場合には、噴出ヘッドへの装着がより容易となる様に筒部にスリット状の切溝を設けても良い。スリット状の切溝は筒部を縦断し設ければ良いが、筒部の背面側でノズル被覆部の下端開口部分に一端を開口する位置に設けると見栄えの点で好ましい。また、ノズルカバーを柔軟で弾力性に富むエラストマーにより形成した場合には、合成樹脂の場合と比較してより装着が容易となる。更に筒部内にノズルの先端開口を開閉可能に閉塞する弁板を一体に形成することもできる。弁板の突設によりノズル内の液の乾燥，固化を防止することができる。弁板は上部より下方に垂設した形態が一般的であるが、側方から横向きに突設しても下方から上向きに突設しても良い。   When the nozzle cover is formed of a synthetic resin, a slit-shaped cut groove may be provided in the cylindrical portion so that the nozzle cover can be easily attached to the ejection head. The slit-shaped kerf may be provided by cutting the cylinder part vertically, but it is preferable in terms of appearance if it is provided at a position where one end is opened at the lower end opening part of the nozzle covering part on the back side of the cylinder part. In addition, when the nozzle cover is formed of a flexible and elastic elastomer, the mounting becomes easier than in the case of a synthetic resin. Furthermore, a valve plate for closing the opening of the tip of the nozzle so as to be openable and closable can be integrally formed in the cylindrical portion. Protrusion of the valve plate can prevent the liquid in the nozzle from drying and solidifying. In general, the valve plate hangs downward from the upper part, but it may project laterally from the side or project upward from the lower side.

本体部は、筒部より一体に延設してノズルの両側及び頂部を覆い且つ噴出ヘッドの頂部及び周囲を被覆して嵌合する形態をなす。但し、噴出ヘッドの押し下げが可能な位置に被覆させる。ノズルカバーを合成樹脂により形成される場合には、噴出ヘッド頂部に位置する本体部の上面に滑り止め用の突部を突設すると良い。この突部の形態は種々採用でき、図示例の如く複数の突起をランダムに突設した形態であっても、或いは多数の線状突部を平行に設けても、格子状に設けても良く、突部の形態は特に限定されない。また、ノズルカバーの装着をより容易とするために、本体部の周壁部分後部に切欠窓を設けても良い。   The main body portion is integrally extended from the cylindrical portion, covers both sides and the top of the nozzle, and covers and fits the top and the periphery of the ejection head. However, it covers the position where the ejection head can be pushed down. When the nozzle cover is formed of a synthetic resin, a non-slip projection may be provided on the upper surface of the main body located at the top of the ejection head. Various forms of the protrusions can be adopted, and a plurality of protrusions may be randomly provided as in the illustrated example, or a large number of linear protrusions may be provided in parallel or in a lattice shape. The form of the protrusion is not particularly limited. Moreover, in order to make mounting | wearing of a nozzle cover easier, you may provide a notch window in the peripheral wall part rear part of a main-body part.

第１の手段として、以下の通り構成した。即ち、ノズル13を前方へ突出する噴出ヘッド14を備えたディスペンサーＡに装着するノズルカバーであって、ノズル13先端部外周に一端を嵌着するとともに、他端を下方へ向けて開口する筒部20と、筒部20より一体に延設してノズル13の両側及び頂部を覆い且つ噴出ヘッド14の頂部及び周囲を被覆して嵌合した本体部30とからなり、全体を合成樹脂により形成した。   The first means is configured as follows. That is, a nozzle cover that is attached to a dispenser A having an ejection head 14 that projects the nozzle 13 forward, and has a cylindrical portion that has one end fitted on the outer periphery of the nozzle 13 and opens the other end downward. 20 and a body portion 30 that extends integrally from the cylindrical portion 20 and covers both sides and the top of the nozzle 13 and covers and fits the top and the periphery of the ejection head 14, and the whole is formed of a synthetic resin. .

第２の手段として、以下の通り構成した。即ち、前記第１の手段に於いて、前記筒部20を縦断するスリット状の切溝32を設けた。   The second means is configured as follows. That is, in the first means, a slit-like kerf 32 that vertically cuts the cylindrical portion 20 is provided.

第３の手段として、以下の通り構成した。即ち、前記第１の手段又は第２の手段のいずれかの手段に於いて、前記噴出ヘッド14頂部に位置する本体部30の上面に滑り止め用の突部33を突設した。   The third means was configured as follows. That is, in either the first means or the second means, a non-slip protrusion 33 is provided on the upper surface of the main body 30 located at the top of the ejection head 14.

第４の手段として、以下の通り構成した。即ち、前記第１の手段に於いて、全体を合成樹脂により形成する代わりに全体をエラストマーで形成した。   The fourth means is configured as follows. That is, in the first means, the whole is made of elastomer instead of the whole made of synthetic resin.

第５の手段として、以下の通り構成した。即ち、前記第４の手段に於いて、前記筒部20内にノズル13の先端開口を開閉可能に閉塞する弁板22を突設した。   The fifth means is configured as follows. That is, in the fourth means, a valve plate 22 is provided in the cylindrical portion 20 so as to close the tip opening of the nozzle 13 so that it can be opened and closed.

第６の手段として、以下の通り構成した。即ち、前記第１の手段乃至第５の手段のいずれかの手段に於いて、前記本体部30の後部外周部分に切欠窓34を形成した。   The sixth means is configured as follows. That is, in any one of the first to fifth means, a notch window 34 is formed in the rear outer peripheral portion of the main body 30.

本発明のノズルカバーは、ノズル13先端の開口を下方に向けることができるため、仮にノズル13の先端部分での中身乾燥固化が生じ、中身が通常の狙いの方向に向かなくなるような不具合が確実に防止できる。また、既存のディスペンサーに装着して使用することができるため、簡単に既存のディペンサーの欠点を改良することができる。また、構造は極めて簡単であるため、安価に製造できる利点も兼ね備えている。また、ノズルカバーは比較的簡便に取り付け、取り外しができ、同じノズルに繰り返し使用することができるため実用面での利点もある。   In the nozzle cover of the present invention, since the opening at the tip of the nozzle 13 can be directed downward, there is a problem that the content of the nozzle 13 is dried and solidified at the tip of the nozzle 13 and the content does not face the normal target direction. It can be surely prevented. Moreover, since it can be used by being mounted on an existing dispenser, the drawbacks of the existing dispenser can be easily improved. Moreover, since the structure is extremely simple, it also has the advantage of being inexpensively manufactured. Further, the nozzle cover can be attached and detached relatively easily, and can be used repeatedly for the same nozzle, so that there is an advantage in practical use.

前記筒部20を縦断するスリット状の切溝32を設けた場合には、比較的柔軟性に乏しい合成樹脂材を使用した場合でも、容易に装着が可能となる。   When the slit-like kerf 32 that cuts the cylindrical portion 20 is provided, it is possible to easily attach even when a synthetic resin material having relatively low flexibility is used.

前記噴出ヘッド14頂部に位置する本体部30の上面に滑り止め用の突部33を突設した場合には、噴出ヘッド14の押し下げ操作時に指が滑る等の不都合を防止できる。特に、水場での使用、洗剤等を扱っている場合には有効である。   When the non-slip protrusion 33 is provided on the upper surface of the main body 30 located at the top of the ejection head 14, inconveniences such as a finger slipping when the ejection head 14 is pushed down can be prevented. This is especially effective when used in water or when handling detergents.

全体を合成樹脂により形成する代わりに全体をエラストマーで形成した場合には、全体が柔軟性を備えているため、噴出ヘッド14への装着が容易に行える利点がある。更に吐出口先端部もソフトであるため手触りも良く、安全に使用できる利点も兼ね備えている。また、一般にエラストマーは摩擦係数が大きいものが多く、特に滑り止め用の突部を設けなくても噴出ヘッド14の押し下げ操作時に指が滑る等の不都合を防止できる。   In the case where the whole is formed of an elastomer instead of being formed entirely of synthetic resin, the whole has flexibility, so that there is an advantage that the mounting to the ejection head 14 can be easily performed. Furthermore, since the tip of the discharge port is soft, it is easy to touch and has the advantage of being safe to use. In general, many elastomers have a large coefficient of friction, and in particular, it is possible to prevent inconveniences such as finger slipping when the ejection head 14 is pushed down without providing a non-slip projection.

全体をエラストマーで形成し、前記筒部20内にノズル13の先端開口を開閉可能に閉塞する弁板22を突設した場合には、弁板22により常時ノズル13内を外部から遮断できるため、ノズル13の液の乾燥固化も併せて防止できる利点がある。また、エラストマーで形成されているため、筒部20内の所定位置に単に板状に突設するだけで弁板22の機能を発揮できる利点もある。   The whole is formed of an elastomer, and when the valve plate 22 that closes the opening of the nozzle 13 so as to be openable and closable is projected in the cylindrical portion 20, the inside of the nozzle 13 can always be blocked from the outside by the valve plate 22, There is an advantage that the liquid of the nozzle 13 can be prevented from being dried and solidified together. Further, since it is formed of an elastomer, there is also an advantage that the function of the valve plate 22 can be exhibited simply by projecting in a plate shape at a predetermined position in the cylindrical portion 20.

前記本体部30の後部外周部分に切欠窓34を形成した場合には、装着が極めて容易となる。   When the cutout window 34 is formed in the outer peripheral portion of the rear portion of the main body 30, the mounting becomes extremely easy.

以下、本発明の実施例の形態を図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１はディスペンサーＡに装着した本発明ノズルカバーＢの一例を示す。ディスペンサーＡは、容器体Ｃの口頸部２に装着キャップ10を嵌合させて容器体Ｃに装着しており、装着キャップ10の中央を貫通して上方付勢状態で押し下げ可能にステム11を突設している。ステム11内上端部には吐出弁12を設けており、また、ステム11の上端にノズル13付の噴出ヘッド14を嵌着している。噴出ヘッド14は、ステム11の上端に下部を嵌着した縦筒15を頂壁16の裏面中央部より垂設しており、頂壁16の周縁部から周壁17を垂設している。また、縦筒15の上端部に基端を開口し、周壁17前部を貫通して前方へ筒状のノズル13を突設している。そして、噴出ヘッド14を上方付勢力に抗して押し下げることにより、内蔵ポンプ機構の作用で吐出弁12を介してノズル13より液を噴出する如く構成している。   FIG. 1 shows an example of a nozzle cover B of the present invention mounted on a dispenser A. The dispenser A is attached to the container body C by fitting the mounting cap 10 to the mouth-and-neck portion 2 of the container body C, and penetrates the center of the mounting cap 10 so that the stem 11 can be pushed down in an upward biased state. It is protruding. A discharge valve 12 is provided at the upper end of the stem 11, and an ejection head 14 with a nozzle 13 is fitted to the upper end of the stem 11. In the ejection head 14, a vertical cylinder 15 having a lower portion fitted to the upper end of the stem 11 is suspended from the center of the back surface of the top wall 16, and a peripheral wall 17 is suspended from the peripheral edge of the top wall 16. Further, a base end is opened at the upper end of the vertical cylinder 15, and a cylindrical nozzle 13 is projected forward through the front part of the peripheral wall 17. Then, by pushing down the ejection head 14 against the upward biasing force, the liquid is ejected from the nozzle 13 through the discharge valve 12 by the action of the built-in pump mechanism.

ノズルカバーＢは、筒部20と、本体部30とから構成していおり、全体がポリプロピレン樹脂により一体に形成されている。筒部20は円弧状に湾曲した断面円筒状をなし，一端部内面にノズル13の先端部を嵌合させるための拡径した嵌合部21を形成している。そして、嵌合部21内にノズル13の先端部を嵌合させた際に先端の開口が下方を向く如く湾曲している。   The nozzle cover B is composed of a cylindrical part 20 and a main body part 30, and the whole is integrally formed of polypropylene resin. The cylindrical portion 20 has a circular cross-sectional shape that is curved in an arc shape, and a fitting portion 21 having an enlarged diameter for fitting the tip portion of the nozzle 13 is formed on the inner surface of one end portion. When the tip of the nozzle 13 is fitted into the fitting part 21, the opening at the tip is curved so as to face downward.

本体部30は、筒部20の端部より一体に延設し、ノズル13の両側及び頂部を被覆し、また、噴出ヘッド14の頂部及び周囲を被覆してノズル13及び噴出ヘッド14に嵌着固定している。本体部30は、ノズル13の頂部及び両側を被覆するノズル被覆部30a と、噴出ヘッド14を被覆するヘッド被覆部30b とで構成している。ヘッド被覆部30b の周壁部分内周下端縁に係合突条31を突設して、噴出ヘッド14の周壁17下面に当接係止させ、抜け出し防止を図っている。   The main body 30 extends integrally from the end of the cylindrical portion 20, covers both sides and the top of the nozzle 13, and covers the top and the periphery of the ejection head 14 and is fitted to the nozzle 13 and the ejection head 14. It is fixed. The main body 30 includes a nozzle covering portion 30a that covers the top and both sides of the nozzle 13, and a head covering portion 30b that covers the ejection head 14. An engagement protrusion 31 is provided on the lower end edge of the inner peripheral portion of the peripheral wall portion of the head covering portion 30b, and is brought into contact with and locked to the lower surface of the peripheral wall 17 of the ejection head 14, thereby preventing the head from coming out.

図４及び図５は他の例を示し、図１の例に於いて、筒部20にスリット状の切溝32を設け、また、ヘッド被覆部30b の周壁部分後部に切欠窓34を形成し、更に、ヘッド被覆部30b の頂壁部の上面に滑り止め用の突部33を突設した例を示す。この場合にはスリット状の切溝32の存在で筒部20のノズル13先端への嵌着が容易に行える利点があり、また、切欠窓34の存在でヘッド被覆部30b の嵌合がより容易に行える利点がある。更に、滑り止め用の突部33の存在で噴出ヘッド14の押し下げの際に指が滑るのを防止できる。その他の構成は図１の例と同様であるため、同符号を付して説明を省略する。   4 and 5 show another example. In the example of FIG. 1, a slit-like groove 32 is provided in the cylindrical portion 20, and a notch window 34 is formed at the rear portion of the peripheral wall portion of the head covering portion 30b. Furthermore, an example in which a non-slip protrusion 33 is provided on the upper surface of the top wall portion of the head covering portion 30b is shown. In this case, the presence of the slit-like groove 32 has an advantage that the cylindrical portion 20 can be easily fitted to the tip of the nozzle 13, and the presence of the cutout window 34 makes it easier to fit the head covering portion 30b. There is an advantage that can be done. Furthermore, the presence of the anti-slip protrusion 33 can prevent the finger from slipping when the ejection head 14 is pushed down. The other configuration is the same as that of the example of FIG.

図６及び図７は更に他の例を示し、図１の例に於いて、ノズルカバーＢ全体をポリプロピレンに代えてシリコーンゴムで形成しており、また、筒部20内にノズル13の先端開口を開閉可能に閉塞する弁板22を突設している。また、この場合の筒部20は図８に示す如く、半楕円形状をなしている。この場合には、弁板22の存在でノズル13内の液の乾燥、固化を防止できる作用を兼ね備える。また、シリコーンゴムでノズルカバーＢを形成しているため、噴出ヘッド14の押し下げの際に滑ることがない。その他の構成は図１の例と同様であるため、同符号を付して説明を省略する。   6 and 7 show still another example. In the example of FIG. 1, the entire nozzle cover B is made of silicone rubber instead of polypropylene, and the tip end of the nozzle 13 is opened in the cylindrical portion 20. A valve plate 22 that closes so as to be openable and closable is provided. In this case, the cylindrical portion 20 has a semi-elliptical shape as shown in FIG. In this case, the presence of the valve plate 22 also serves to prevent the liquid in the nozzle 13 from drying and solidifying. Further, since the nozzle cover B is formed of silicone rubber, it does not slip when the ejection head 14 is pushed down. The other configuration is the same as that of the example of FIG.

各例のノズルカバーＢを装着したディスペンサーＡを使用する場合には、噴出ヘッド14の上方を押し下げれば液がノズル13先端より噴出するが、筒部20の存在で噴出された液は下方に方向変換されて噴出する。   When the dispenser A equipped with the nozzle cover B of each example is used, if the upper part of the ejection head 14 is pushed down, the liquid is ejected from the tip of the nozzle 13. The direction is changed and it gushes.
