Description

밸브-조절식 분배용 클로저{VALVE-CONTROLLED DISPENSING CLOSURE}VALVE-CONTROLLED DISPENSING CLOSURE

본 발명은 개구를 가지는 용기로부터 향수와 같은 액체를 분배하기 위한 분배 클로저에 관한 것이다. The present invention relates to a dispensing closure for dispensing a liquid such as perfume from a container having an opening.

미국 특허 제7,681,750호 문헌은 자유-유동 제품을 유지하는 용기용 클로저(closure)에 대해 설명하고 있다. 이 용기는 목부(neck)를 밀봉하기 위하여 용기 개구를 둘러싸는 용기 목부에 체결될 수 있는 고정형 하부; 자유-유동 제품용 통로를 형성하는 돌출 연결 부재를 포함하는 커버; 외부 휴지 위치와 내부 작동 위치 사이에 용기 방향으로 그리고 그에 대항하여 하부 위에서 동축으로 이동할 수 있는 이동가능한 상부; 상부의 하측을 밀봉하는 상부 에지와 신축성 탄성 소재로 적어도 구성되는 베이스를 가지는 브레이커 또는 접시-형상의 다이어프램 밸브; 상부의 시험 위치에서 닫혀지는 다이어프램 밸브의 베이스의 천공들; 및 연결 부재의 내부 단면보다 큰 베이스 직경부를 포함한다. 연결 부재의 외측 단부는 다이어프램 밸브의 베이스를 연속적으로 지지하고, 다이어프램 밸브의 베이스는, 축방향 압력이 용기 방향으로 상부에 가해지는 때에 다이어프램 밸브가 외측으로 굽혀져서 베이스의 천공들을 개방시킬 수 있도록, 휴지 위치의 방향으로 상부를 연속적으로 미리 긴장시킨다. US Pat. No. 7,681,750 describes a closure for a container holding a free-flowing product. The container has a fixed bottom that can be fastened to the container neck surrounding the container opening to seal the neck; A cover comprising a protruding connecting member defining a passageway for a free-flowing product; A moveable top movable coaxially from above to below in relation to and against the vessel between the external rest position and the internal operating position; A breaker or dish-shaped diaphragm valve having a top edge sealing the lower side of the top and a base at least composed of an elastic elastic material; Perforations in the base of the diaphragm valve closed at the upper test position; And a base diameter portion larger than the inner cross section of the connecting member. The outer end of the connecting member continuously supports the base of the diaphragm valve, and the base of the diaphragm valve allows the diaphragm valve to bend outward to open the perforations of the base when axial pressure is applied to the upper side in the container direction, The upper part is continuously pretensioned in the direction of the rest position.

그러나, 유체가 디스펜서에서 방출될 수 있게 하기 위해 너무 큰 압력이 용기에 가해지면, 유체 채널을 통해 공기가 용기에 유입할 수 있으며 유체 채널 내부의 압력이 유체 채널 외부 압력, 즉, 대기압과 달라짐에 따라 유체가 용이하게 스며 나올 수 있다.However, if too much pressure is applied to the vessel to allow fluid to be released from the dispenser, air may enter the vessel through the fluid channel and the pressure inside the fluid channel will be different from the pressure outside the fluid channel, i.e. atmospheric pressure. Therefore, the fluid can easily bleed out.

그러한 누설을 피하기 위하여 캡이 제공될 수 있는데, 이 또한 상기 문헌에 개시되어 있다. Caps may be provided to avoid such leakage, which is also disclosed in the above document.

미국 특허 출원 공개 US 2007/02843397호 문헌은 또한 밸브 위에 배치된 판에 복수의 노즐들을 가지는 분배 클로저를 개시한다. 복수의 노즐들에 의해 안개 등이 분무될 수 있다. 다시 누설을 방지하기 위하여 캡이 제공된다. The document US 2007/02843397 also discloses a dispensing closure having a plurality of nozzles in a plate disposed above the valve. Fog or the like may be sprayed by the plurality of nozzles. Again a cap is provided to prevent leakage.

많은 다른 밸브 장치가 알려져 있다. 예컨대, 유럽 특허 공보 EP 1953432호 문헌은 압력해제 밸브로서의 우산-형태의 밸브를 도시한다. 일반적으로, 우산 밸브들은 다이어프램 형상의 실링 디스크 또는 우산 형상을 가지는 탄성 밸브 부품들이다. 이들 탄성 부품들은 일반적으로 역류방지기구 또는 일방향 밸브 등의 실링 부재들로서 사용된다. 시트에 장착될 때, 볼록한 다이어프램은 밸브 시트에 대해 평탄해지고 일정한시트 요철부들을 흡수하고 일정한 밀봉 힘을 생성한다. 일단 헤드 압력이 시트로부터 볼록한 다이어프램을 들어올리기에 충분한 힘을 생성하면 우산 밸브는 전방향으로의 흐름을 허용하며 이 밸브는 한 방향으로 정해진 압력에서 흐르는 것을 허용할 것이며 반대 방향으로 역류하는 것을 즉시 방지할 것이다. Many other valve arrangements are known. For example, the document EP-1953432 shows an umbrella-type valve as a pressure release valve. In general, umbrella valves are diaphragm sealing disks or elastic valve parts having an umbrella shape. These elastic parts are generally used as sealing members, such as a non-return mechanism or a one-way valve. When mounted to the seat, the convex diaphragm flattens against the valve seat and absorbs constant seat irregularities and creates a constant sealing force. Once the head pressure generates enough force to lift the convex diaphragm from the seat, the umbrella valve will allow flow in all directions and the valve will allow flow at a given pressure in one direction and immediately prevent backflow in the opposite direction. something to do.

그러한 우산 밸브는 큰 단점을 가진다. 예컨대, 5 mbar(0.5 kPa)의 압력에서 밸브는 통상적으로 적어도 8 cm의 직경을 가진다. Such umbrella valves have a big disadvantage. For example, at a pressure of 5 mbar (0.5 kPa), the valve typically has a diameter of at least 8 cm.

본 발명은 종래기술의 문제점들을 해소하기 위하여 착안된 것으로 첨부된 특허청구범위에 규정된 바와 같은 소형의 분배 클로저를 제공한다. The present invention provides a compact dispensing closure as defined in the appended claims as conceived to solve the problems of the prior art.

본 발명의 분배 클로저는 캡이 없이도 액체 밀봉을 보장하며, 예컨대, 표준의 병 목부 직경을 가지는 향수병에 사용될 수 있을 정도로 충분히 작다. The dispensing closure of the present invention ensures liquid sealing without a cap and is small enough to be used, for example, for perfume bottles with a standard bottle neck diameter.

본 발명의 다른 세부 사항들과 변형들은 종속 청구항들에 규정된다. Other details and modifications of the invention are defined in the dependent claims.

본 발명에 따른 분배 클로저의 바람직한 실시예가 이제 도면들을 참조하여 설명될 것이다. A preferred embodiment of the dispensing closure according to the invention will now be described with reference to the drawings.

도 1 및 도 2는 본 발명에 따른 분배 클로저(2)가 위에 장착된 유체 용기(3)를 도시한다. 용기와 삽착 클로저의 조합은 일반적으로 부호(1)로 표시된다. 1 and 2 show a fluid container 3 with a dispensing closure 2 according to the invention mounted thereon. The combination of the container and the insert closure is generally indicated by the symbol (1).

용기(3)는 로션, 크림, 향수 등과 같은 자유-유동 제품을 유지할 수 있으며 통상적으로 배출 개구를 가지는 목부(neck)가 구비된다. 용기는 유리나 세라믹, 또는 플라스틱과 같은 고체 재료로 구성될 수 있으므로, 플라스틱 용기의 벽은 단단하거나 신축성이다. 용기(3)의 목부에는 이 기술 분야에 잘 알려진 방식으로 분무용 상부가 목부에 삽착될 수 있도록 나사가 제공될 수 있다.The container 3 can hold free-flowing products such as lotions, creams, perfumes and the like and is typically provided with a neck having a discharge opening. Since the container can be made of a solid material such as glass, ceramic, or plastic, the wall of the plastic container is rigid or stretchable. The neck of the container 3 may be provided with screws such that the spraying top can be inserted into the neck in a manner well known in the art.

분배 클로저(2)는 기본적으로 용기를 액체 밀봉 방식으로 밀봉하기 위하여 용기(3)의 목부에 삽착될 수 있는 플러그에 대응한다. The dispensing closure 2 basically corresponds to a plug that can be inserted into the neck of the container 3 to seal the container in a liquid sealing manner.

도 3은 또한 플러그(2)로 표시된 분배 클로저를 보다 상세하게 도시한다. 플러그(2)는 플러그 캡(21), 듀얼밸브 다이어프램(22) 및 플러그 본체(23)의 세 부품들로 구성된다. 플러그로부터 방출하기 위하여 용기(3)의 액체로부터 플러그로 운송할 수 있도록 튜브 또는 로드(24)가 플러그 본체에 삽착될 수 있다. 플러그 본체(23)는 듀얼밸브 다이어프램(22)을 수용하도록 상부 부분을 가지며 플러그 캡(21)은 플러그를 밀봉하기 위하여 듀얼밸브 다이어프램(22)의 상부에 삽착된다. 3 also shows in more detail the dispensing closure indicated by plug 2. The plug 2 is composed of three parts: a plug cap 21, a dual valve diaphragm 22, and a plug body 23. Tubes or rods 24 may be inserted into the plug body for transporting from the liquid in the container 3 to the plug for ejection from the plug. The plug body 23 has an upper portion to receive the dual valve diaphragm 22 and the plug cap 21 is inserted on top of the dual valve diaphragm 22 to seal the plug.

도 4는 플러그의 단면도와 플러그 캡(21)의 평면도를 도시한다.4 shows a sectional view of the plug and a plan view of the plug cap 21.

도시로부터 알 수 있는 바와 같이, 플러그 캡(21)은 디스크-형상이며 중심 개구를 둘러싸는 하나 이상의 통기 슬롯(21c)을 가진 중심 개구(21d)가 구비된다. 이하에서 보다 상세하게 설명되는 바와 같이, 플러그 캡 아래 위치된 밸브 내로 튜브나 캐뉼러가 삽입될 때, 통기 슬롯(21c)과 중심 개구(21d) 사이에는 액체 누출을 방지하기 위하여 내부 링 시일(21a)이 제공된다. As can be seen from the figure, the plug cap 21 is provided with a central opening 21d having one or more vent slots 21c that are disc-shaped and surround the central opening. As described in more detail below, when a tube or cannula is inserted into a valve positioned below the plug cap, the inner ring seal 21a to prevent liquid leakage between the vent slot 21c and the center opening 21d. ) Is provided.

듀얼 밸브 다이어프램(22)은, 실리콘, 고무와 같은 신축성 탄성 소재, 폴리에틸렌과 같은 플라스틱, 또는 유사한 탄성 소재로 구성된다. 듀얼 밸브 다이어프램(22)은 밸브 시일(22c)에 의해 둘러싸인 중심 슬릿-형태의 오리피스(22a)를 가지는 중심 밸브 부분(22b)을 포함한다. 우산-형태 밸브(22d)를 구성하는 둘레 부분이 추가로 제공되어 밸브 시일(22c)을 둘러싼다. 그러한 슬릿-형태의 오리피스는, 예컨대, 위에 인용된 미국 특허 US 7,681,750호 문헌에서 공지된 것이다. 도시된 바와 같이, 복수의 슬릿들이 균등한 원주상 각도 거리들에서 중심 밸브 부분(22d)의 중심을 관통하여 직경상으로 단면-형상 또는 별-형상으로 연장한다. 슬릿들의 단부들은 밸브 시일(22c)로부터 적절한 반경 거리에 위치된다. The dual valve diaphragm 22 is made of a stretchable elastic material such as silicone, rubber, plastic such as polyethylene, or similar elastic material. The dual valve diaphragm 22 includes a central valve portion 22b having a central slit-shaped orifice 22a surrounded by a valve seal 22c. A circumferential portion constituting the umbrella-shaped valve 22d is further provided to surround the valve seal 22c. Such slit-shaped orifices are known, for example, from US Pat. No. 7,681,750, cited above. As shown, a plurality of slits extend through the center of the center valve portion 22d at equal circumferential angular distances and extend cross-sectional or star-shaped in diameter. The ends of the slits are located at an appropriate radial distance from the valve seal 22c.

플러그 본체(23)는 유체를 유지하는 용기의 목부에 삽착되기 위한 긴 원형의 주 몸통(23d)과 목부를 밀봉하기 위하여 목부 상부에 착좌되는 일반적으로 디스크-형상의 상부 부분(23e)을 가진 플러그 형상을 가진다. 상부 부분(23e)은 플러그(2)가 위에 삽착되는 용기의 목부와 실질적으로 같은 외경을 가진다. 예로서, 이 직경은 향수병에 대한 표준 FEA 15 크기인 15㎜일 수 있다. The plug body 23 is a plug having an elongated main body 23d for insertion into the neck of the container holding the fluid and a generally disk-shaped upper part 23e seated on the neck top to seal the neck. It has a shape. The upper part 23e has an outer diameter substantially equal to the neck of the container into which the plug 2 is inserted. By way of example, this diameter may be 15 mm, which is the standard FEA 15 size for perfume bottles.

주 몸통(23d)은 용기(3)의 목부에 꼭 맞게 삽착되는 외측의 길다란 원통형 부분을 가진다. 링 시일(23a)은 용기와 플러그 사이의 누설을 방지하기 위하여 주 몸통(23d)의 외주 위에 제공될 수 있다. 주 몸통(23d)은 또한 그 자체 딥(dip)-튜브(24)를 수용하기 위한 중공 딥 튜브 시트(23c)를 가지는 외측의 길다란 원통형 부분으로부터 이격된 내부의 길다란 원통형 부분을 가진다. 하나 이상의 링들, 도시된 예에서는 3개의 링들이 용기 내측으로부터 딥-튜브로의 공기 유입을 방지하기 위하여 제공될 수 있다. The main body 23d has an outer elongate cylindrical portion that fits snugly into the neck of the container 3. The ring seal 23a may be provided on the outer circumference of the main body 23d to prevent leakage between the container and the plug. The main body 23d also has an internal elongated cylindrical portion spaced from the outer elongated cylindrical portion with a hollow dip tube sheet 23c for receiving the dip-tube 24 itself. One or more rings, in the example shown three rings, may be provided to prevent air entry into the dip-tube from inside the vessel.

상부 부분(23e)에는 또한 상면에 이들 부재들 사이의 기밀 조립을 보장하기 위하여, 예컨대, 레이저 용접 등에 의하여(도 5의 C 부분 참조), 플러그 캡(21)의 하면에 적절히 배치된 슬롯에 고정되는 용접 링(23f)이 제공된다. 또한 이들 부재들 사이의 기밀 조립을 보장하기 위하여 플러그 캡(21)의 하면에 적절히 배치된 추가적인 슬롯과 정렬되는 측벽(23g)들에 의해 제한되는 중심 리세스(23h)가 제공된다. 리세스(23h)는 듀얼밸브 다이어프램(22)을 수용하도록 구성되고 다이어프램(22)의 통기 슬롯(21c)들과 적절하게 축방향으로 정렬되는 통기 슬롯들이 제공된다. 주 몸통(23d)의 내부의 긴 부분이 이러한 리세스 내로 연장하며 다이어프램 편향 챔버를 구성하는 상부의 중공 부분(23b)을 가진다. 이는 딥-튜브(24)가 다이어프램과 튜브 사이의 충돌을 방지하기 위하여 삽입될 때 사용되는 공간이다. 이러한 중공 부분(23b)의 측벽들은 그와 정렬된 다이어프램(22)의 밸브 시일(22c)을 수용하기 위한 어깨부를 구성한다.The upper part 23e is also fastened to a slot properly disposed on the lower surface of the plug cap 21, for example, by laser welding or the like (see part C of FIG. 5) to ensure an airtight assembly between these members on the upper surface. The welding ring 23f is provided. A central recess 23h is also provided, which is limited by sidewalls 23g that align with additional slots appropriately disposed on the bottom surface of the plug cap 21 to ensure hermetic assembly between these members. The recess 23h is configured to receive the dual valve diaphragm 22 and is provided with vent slots that are properly axially aligned with the vent slots 21c of the diaphragm 22. An elongated portion inside the main body 23d has an upper hollow portion 23b extending into this recess and constituting the diaphragm deflection chamber. This is the space used when the dip tube 24 is inserted to prevent a collision between the diaphragm and the tube. The side walls of this hollow portion 23b constitute a shoulder for receiving the valve seal 22c of the diaphragm 22 aligned therewith.

다이어프램(22)은, 플러그 캡(21)이 플러그를 닫기 위하여 삽착될 때에 밸브 시일(22c)이 측벽들과 플러그 캡 사이에서 압축되어 편향 부재(23b)의 액체 밀봉을 보장할 수 있도록, 리세스(23h)에 삽착된다. 도 4에 도시된 바와 같이, 이들 어깨부들은, 둘레 밸브 부분; 슬릿-형태의 오리피스(22a)를 가지는 정상적으로 닫히는 밸브를 구성하는 내부 밸브 부분, 여기서 상기 오리피스는 내부 밸브 부분이 휴지 위치에 있을 때 닫혀짐; 우산 형태의 밸브(22b)를 구성하는 외부 밸브 부분으로 구분하여 다이어프램(22)을 고정한다. 우산-형태 밸브(22b)는 또한 휴지 위치에서 플러그 캡(21)의 통기 슬롯들을 닫으며 플러그 캡(21) 위에 밸브 시트가 있는 정상적으로 닫힌 밸브이다. 위로부터 알 수 있는 바와 같이, 우산-형태 밸브(22b)는 이어서 플러그 캡(21)의 통기 슬롯(21c)을 차단한다. The diaphragm 22 is recessed so that when the plug cap 21 is inserted to close the plug, the valve seal 22c can be compressed between the side walls and the plug cap to ensure liquid sealing of the deflection member 23b. It is inserted in 23h. As shown in FIG. 4, these shoulders include a circumferential valve portion; An inner valve portion constituting a normally closed valve having a slit-shaped orifice 22a, wherein the orifice is closed when the inner valve portion is in the resting position; The diaphragm 22 is fixed by dividing into an outer valve portion constituting the umbrella-shaped valve 22b. The umbrella-type valve 22b is also a normally closed valve that closes the vent slots of the plug cap 21 in the rest position and has a valve seat over the plug cap 21. As can be seen from above, the umbrella-type valve 22b then blocks the vent slot 21c of the plug cap 21.

이제부터는 본 발명에 따른 듀얼 밸브 다이어프램의 작동에 대해 도 5를 참고하여 설명한다. The operation of the dual valve diaphragm according to the present invention will now be described with reference to FIG. 5.

듀얼 밸브 다이어프램(22)은 자체-닫힘 슬릿-형태 밸브(22a)와 정상적으로 닫힌 우산-형태의 밸브를 가진 정상적으로 닫힌 오리피스를 포함한다. 용기로부터 액체가 분배될 때, 펌프에 의해 흡입이 실행되거나 슬릿-형태 오리피스(22a)를 통해 용기에 가해진 압력에 의해 흡입이 실행된다. 도 5에 도시된 화살표, "통로 B" 방향으로 플러그와 용기의 외부로 유체가 흐를 수 있도록 슬릿-형태의 오리피스(22a)는 개방된다. 이로써, 용기 내부에 압력이 생성되고 액체는 개방된 오리피스(22)를 통해 딥-튜브(24)와 플러그로부터 배출된다. 이러한 압력은 예컨대, 향수 분무시, 5 내지 10 mbar 정도이다. The dual valve diaphragm 22 includes a normally closed orifice having a self-closing slit-type valve 22a and a normally closed umbrella-type valve. When liquid is dispensed from the container, suction is performed by a pump or by pressure applied to the container through the slit-shaped orifice 22a. The slit-shaped orifice 22a is opened to allow fluid to flow out of the plug and container in the direction shown by the arrow, “Path B”. This creates a pressure inside the vessel and the liquid exits the dip tube 24 and the plug through the open orifice 22. This pressure is on the order of 5 to 10 mbar, for example when spraying perfume.

이러한 압력에 기인하여, 우산-형태의 밸브는 개방되고 통기 슬롯(21c)과 플러그 캡(23)의 대응하는 슬롯을 통해 도 5 도시와 같은 화살표 “통로 A" 방향으로 용기(3) 내로 공기가 유동할 수 있다. 이와 같이, 용기 내측의 디프레션(depression)은 일정 양의 액체가 분배될 때 생성된다. 분무된 부피는 생성된 디프레션에 의해 개방된 우산-형태의 밸브에 의한 공기 흐름에 의해 얻어진 용기 내외측의 평형 압력을 가지기 위하여 공기에 의해 대체된다. Due to this pressure, the umbrella-shaped valve is opened and air is introduced into the container 3 in the direction of the arrow “path A” as shown in FIG. 5 through the corresponding slot of the vent slot 21c and the plug cap 23. In this way, the depression inside the vessel is produced when a certain amount of liquid is dispensed in. The sprayed volume is obtained by the air flow by an umbrella-shaped valve opened by the resulting depression. It is replaced by air to have an equilibrium pressure inside and outside the vessel.

이와 같이, 밸브들이 닫히면, 도 5에 도시된 바와 같이, 유지력 A와 유지력 B에 의해 액체가 저장실에 유지된다. 이로써 병이 캐뉼러 시스템에 연결되지 않은 때나 병이 리드를 가지지 않은 때, 액체의 비산을 방지할 수 있다. As such, when the valves are closed, the liquid is held in the storage chamber by the holding force A and the holding force B, as shown in FIG. This prevents the liquid from scattering when the bottle is not connected to the cannula system or when the bottle has no lead.

이제 본 발명의 바람직한 실시예들이 설명되었으므로, 그의 개념을 구현하는 다른 실시예들이 사용될 수 있음은 이 기술 분야의 통상의 기술자에게 명백할 것이다. 따라서, 본 발명은 개시된 실시예들에 제한되지 않으며, 오히려 첨부의 특허청구범위의 범위에 의해서만 제한되어야 한다.
