Description

【０００１】
【発明の属する技術分野】
本発明は、容器内に収容した、香水、整髪料などの内容物を噴出させて用いるためのスプレー容器、特に容器を倒立状態にした場合でも内容物を噴出させることのできる、正倒立両用スプレーに関するものである。
【０００２】
【従来の技術】
かかるスプレー容器として、例えば実公昭60-36364号公報、実公昭60-26839号公報および実公昭61-899号公報に記載のものがある。
【０００３】
これらの容器は、いずれも、シリンダ内にボール弁式の吸込弁および空気阻止弁が上下に配置され、正立状態では通常のスプレー容器と同様に動作し、一方倒立状態では空気阻止弁が容器内の空気がシリンダ内に入り込むのを防ぐように働く。
【０００４】
しかしながら、こうした容器においては、弁体としてのボールにシリンダ内での跳びやガタつきといった不所望の運動が生じた場合、それによって噴霧される内容物の量が一定しなくなるという問題があった。
【０００５】
【発明が解決しようとする課題】
本発明は上記の問題点を解決し、常に一定量の内容物を噴霧することのできる正倒立両用スプレー容器を提案するものである。
【０００６】
【課題を解決するための手段】
すなわち本発明は、容器本体に固定されるキャップと、前記キャップの前記容器本体への固定と共に前記容器本体に固定されるシリンダと、前記シリンダ内部に配置したピストンガイドと、前記ピストンガイドに案内されて前記シリンダ内部を摺動するピストンと、前記ピストンと前記ピストンガイドとの間に配置したばねとを具え、前記シリンダ内部に吸込弁および空気阻止弁を直列に配置して設けた正倒立両用スプレー容器において、前記吸込弁および前記空気阻止弁の各弁体の移動を規制するストッパを一体に形成し、このストッパを前記シリンダ内を摺動可能としたことを特徴とするものである。
【０００７】
本発明による正倒立両用スプレー容器においては、吸込弁と空気阻止弁のそれぞれの弁体の移動を規制するストッパを一体化し、かつ、このストッパがシリンダ内を摺動可能としている。そのため、正立・倒立いずれの状態においても、吸込弁と空気阻止弁の各弁体の一方が弁座に着座し、かつストッパによって移動を規制された状態に置かれることとなる。それゆえ、弁体の跳びやガタつきといった不所望の運動を抑えることが可能となり、常に一定量の内容物を噴霧させることができるようになる。
【０００８】
【発明の実施の形態】
以下、図面を参照して本発明の好適な実施形態について説明する。
【０００９】
図１および図２は、本発明による正倒立両用スプレー容器の一実施形態を示すものである。図１は容器全体を、図２はポンプ部分の詳細をそれぞれ示すものである。図示の正倒立両用スプレー容器11は、容器本体12にねじ止めにより固定されるキャップ13と、シリンダ14と、シリンダ14内に延在させたピストンガイド15と、このピストンガイド15に案内されてシリンダ14内を上下方向に摺動するピストン16と、ピストン16下端部とピストンガイド15の基部15aとの間に介在させたばね17、容器本体12とシリンダ14との間に設けたパッキン18とを具える。
【００１０】
シリンダ14の下部には吸込弁19が形成されている。吸込弁19は、弁体であるボール20、弁座21、弁孔22および弁室23からなる。一方ピストンガイド15の下端部には空気阻止弁24が形成されている。空気阻止弁24も、弁体であるボール25、弁座26、弁孔27および弁室28からなる。
【００１１】
シリンダ14内の、吸込弁19と、空気阻止弁24との間には円筒体29が挿入され、この円筒体29内面を摺動するようにストッパ30が嵌挿されている。ストッパ30は、吸込弁19の弁体20および空気阻止弁24の弁体25の不用意な移動を規制するために設けられたものであり、３本の足31からなる吸込弁側ストッパ部32と、窪み33からなる空気阻止弁側ストッパ部34が、背中合わせに一体に形成されている。図３は、このストッパ30を下側、すなわち吸込弁側ストッパ部32から見たものである。図示のように、ストッパ30には、内容物が流通できるように流通孔35，36が設けられている。
【００１２】
次に、このストッパ30の作用について説明する。まず、図１および図２に示すような正立状態においては、吸込弁19の弁体20は弁座21に着座すると共に、その上にストッパ30が乗せられた状態になっている。このとき、図示のようにストッパ30の空気阻止弁側ストッパ部34上に空気阻止弁24の弁体25が着座しているため、弁体20は、ストッパ30およびその上に着座している空気阻止弁24の弁体25の重量により、不所望の移動が抑えられることとなる。
【００１３】
一方、倒立状態においては、ストッパ30が円筒体29の内側を空気阻止弁24側へと移動し、正立状態とは逆に、空気阻止弁24の弁体25が弁座26に着座すると共に、その上にストッパ30が乗せられた状態になる。このとき、吸込弁19の弁体20がストッパ30の吸込弁側ストッパ部32上に着座することとなり、それゆえ、弁体25は、ストッパ30およびその上に着座している吸込弁19の弁体20の重量により、不所望の移動が抑えられることとなる。
【００１４】
以上説明したように、本発明による正倒立両用スプレー容器においては、吸込弁および空気阻止弁それぞれの弁体のガタつき等の不所望の移動を抑えるため、吸込弁と空気阻止弁のそれぞれの弁体の移動を規制するストッパを一体化し、かつ、このストッパがシリンダ内を摺動可能としている。そのため、正立・倒立いずれの状態においても、吸込弁と空気阻止弁の各弁体の一方が弁座に着座し、かつストッパによって移動を規制された状態に置かれることとなる。したがって、弁体の跳びやガタつきといった不所望の運動を抑えることが可能となり、常に一定量の内容物を噴霧させることができるようになる。

BACKGROUND OF THE INVENTION
The present invention relates to a spray container for injecting and using contents such as perfume and hair styling contained in a container, and in particular, an upside-down dual-purpose spray capable of ejecting contents even when the container is inverted. It is about.
[0002]
[Prior art]
Examples of such spray containers include those described in Japanese Utility Model Publication Nos. 60-36364, 60-26839 and 61-899.
[0003]
Each of these containers has a ball valve type suction valve and an air blocking valve arranged vertically in the cylinder, and operates in the same manner as a normal spray container in an upright state, while in an inverted state, the air blocking valve is a container. It works to prevent air from entering the cylinder.
[0004]
However, in such a container, when an undesired movement such as jumping or rattling occurs in the ball as the valve body, there is a problem that the amount of the content sprayed becomes unstable.
[0005]
[Problems to be solved by the invention]
The present invention solves the above-mentioned problems and proposes an upside-down dual-purpose spray container that can always spray a certain amount of contents.
[0006]
[Means for Solving the Problems]
That is, the present invention includes a cap fixed to a container body, a cylinder fixed to the container body together with the cap fixed to the container body, a piston guide disposed in the cylinder, and the piston guide. A spray that is disposed between the piston and the piston guide, and is provided with a suction valve and an air blocking valve arranged in series inside the cylinder. In the container, a stopper for restricting movement of each valve body of the suction valve and the air blocking valve is integrally formed, and this stopper can be slid in the cylinder.
[0007]
In the upside-down dual-purpose spray container according to the present invention, a stopper for restricting the movement of the valve body of each of the suction valve and the air blocking valve is integrated, and the stopper can slide in the cylinder. Therefore, in either the upright state or the inverted state, one of the valve bodies of the suction valve and the air blocking valve is seated on the valve seat, and the movement is restricted by the stopper. Therefore, it is possible to suppress undesired movements such as jumping and rattling of the valve body, and it becomes possible to always spray a certain amount of contents.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 and FIG. 2 show one embodiment of the upside-down dual-purpose spray container according to the present invention. FIG. 1 shows the entire container, and FIG. 2 shows details of the pump part. The illustrated upside-down dual-purpose spray container 11 includes a cap 13 fixed to the container body 12 by screwing, a cylinder 14, a piston guide 15 extending into the cylinder 14, and a cylinder guided by the piston guide 15. 14 includes a piston 16 that slides in the vertical direction, a spring 17 interposed between the lower end portion of the piston 16 and the base portion 15a of the piston guide 15, and a packing 18 provided between the container body 12 and the cylinder 14. Yeah.
[0010]
A suction valve 19 is formed in the lower part of the cylinder 14. The suction valve 19 includes a ball 20, which is a valve body, a valve seat 21, a valve hole 22, and a valve chamber 23. On the other hand, an air blocking valve 24 is formed at the lower end of the piston guide 15. The air blocking valve 24 also includes a ball 25 that is a valve body, a valve seat 26, a valve hole 27, and a valve chamber 28.
[0011]
A cylindrical body 29 is inserted between the suction valve 19 and the air blocking valve 24 in the cylinder 14, and a stopper 30 is inserted so as to slide on the inner surface of the cylindrical body 29. The stopper 30 is provided to restrict inadvertent movement of the valve body 20 of the suction valve 19 and the valve body 25 of the air blocking valve 24. The stopper 30 is composed of three legs 31. In addition, an air blocking valve side stopper portion 34 composed of a recess 33 is formed integrally back to back. FIG. 3 shows the stopper 30 viewed from the lower side, that is, the suction valve side stopper portion 32. As shown in the figure, the stopper 30 is provided with flow holes 35 and 36 so that the contents can flow.
[0012]
Next, the operation of the stopper 30 will be described. First, in the upright state as shown in FIGS. 1 and 2, the valve body 20 of the suction valve 19 is seated on the valve seat 21 and the stopper 30 is placed thereon. At this time, since the valve body 25 of the air blocking valve 24 is seated on the air blocking valve side stopper portion 34 of the stopper 30 as shown in the drawing, the valve body 20 includes the stopper 30 and the air seated thereon. Undesirable movement is suppressed by the weight of the valve body 25 of the blocking valve 24.
[0013]
On the other hand, in the inverted state, the stopper 30 moves inside the cylindrical body 29 toward the air blocking valve 24, and contrary to the upright state, the valve body 25 of the air blocking valve 24 is seated on the valve seat 26. In this state, the stopper 30 is placed thereon. At this time, the valve body 20 of the suction valve 19 is seated on the suction valve side stopper portion 32 of the stopper 30, so that the valve body 25 is the valve of the stopper 30 and the suction valve 19 seated thereon. Undesired movement is suppressed by the weight of the body 20.
[0014]
As described above, in the forward and reverse dual-use spray container according to the present invention, in order to suppress undesired movement such as rattling of the valve bodies of the suction valve and the air blocking valve, the respective valves of the suction valve and the air blocking valve A stopper for restricting the movement of the body is integrated, and this stopper can slide in the cylinder. Therefore, in either the upright state or the inverted state, one of the valve bodies of the suction valve and the air blocking valve is seated on the valve seat, and the movement is restricted by the stopper. Therefore, it is possible to suppress undesired movements such as jumping and rattling of the valve body, and it becomes possible to always spray a certain amount of contents.
