Description

  The present invention relates to a spout for taking out the contents of a container by tilting with the mouth of the container facing downward or holding the container in an inverted posture and pushing a protrusion at a tip opening.

The extraction stopper that removes the contents of the container by pushing the protrusion protruding from the tip opening will immediately restore the protrusion to the initial position by the repulsive force of the elastic member when the pushing operation is released, and close the tip opening. And is free from dripping, and has the advantage of avoiding as much as possible the contents of the container from touching the outside air, and is frequently used for containers filled with cosmetics and medicines (for example, see Patent Document 1). .
Utility Model Registration No. 2553493

  However, since such a spout tap increases the internal pressure of the container, for example, when the temperature rises in the container during storage, if the lid is opened as it is, a large amount of liquid will be poured out. There has been a problem that the content liquid has been poured out and scattered.

  The problem to be solved by the present invention is that the contents are excessively poured out as the internal pressure of the container increases, and the object of the present invention is to reduce the increase in the internal pressure of the container at the time of dispensing. The object is to provide a spout capable of pouring contents in a range.

The present invention is fixedly held at the mouth of the container, and is supported through an elastic member on the inside of the dispensing cylinder, the dispensing cylinder that causes the contents of the container to flow out to the outside through the tip opening, A flow rate adjusting valve element that contacts the inner seating surface of the dispensing cylinder and maintains the opening of the tip in a sealed state. The flow regulating valve element passes through the tip opening of the dispensing cylinder. Provided with a push-in projection that opens the tip opening by exposing the exposed portion to the outside and separating the flow rate adjusting valve body from the inner seat surface of the extraction cylinder,
An internal passage that leads to the outside through the tip opening of this push-in projection is formed in the valve body for flow rate adjustment,
Provided below the flow regulating valve body is a member that forms an internal space with the valve body,
In this member, while forming a first small hole that allows the mouth of the container to communicate with the internal space,
The flow rate adjusting valve element is formed with a second small hole that allows the internal space to communicate with the outside through the internal passage.

  Each of the first and second small holes according to the present invention is preferably set so as to allow the flow of air while preventing the flow of the internal solution. However, the cross-sectional areas of the two small holes (for example, “diameter” in the case of a round hole) may be the same, or one of them may be larger than the other. Furthermore, in the present invention, a ball valve can be disposed in the internal space.

  According to the present invention, even if the internal pressure of the container is increased, the internal pressure is introduced into the internal space from the first small hole, and then is passed through the internal passage through the second small hole to open the tip of the pushing protrusion. Escape from the hole to the outside world. Therefore, according to the present invention, the increase in the internal pressure of the container can be reduced and the contents can be poured out in a suitable range.

  Further, in the present invention, the first small hole communicates with the internal space, and this internal space further communicates with the outside through the second small hole. Therefore, even when the inner solution flows from the first small hole, Since the space functions as a liquid reservoir, the dripping is delayed until a certain time without being dripped quickly from the tip opening of the pushing protrusion. For this reason, in the present invention, even when the inner solution flows from the first small hole, liquid dripping hardly occurs.

  In addition, in the present invention, if a ball valve is disposed in the internal space, liquid dripping from the second small hole can be more reliably prevented.

  Reference numeral 4 denotes an elastic member (resin spring or the like) disposed inside the dispensing cylinder 2 (internal passage 2a). The elastic member 4 includes an elastic portion main body (spring main body) 4a and a hollow annular base portion 4b that is integrally connected to the spring main body 4a and supports the spring main body 4a.

Reference numeral 5 denotes a flow rate adjusting valve element (hereinafter referred to as “flow rate adjusting valve element”) integrally held by the elastic member 4 (spring body 4a). The flow rate adjusting valve body 5 has a tapered surface F ₁₅ that abuts against an inner seat surface F ₁₂ provided in the internal passage 2 a of the dispensing cylinder 2, and the tip opening 2 b is formed by the urging force from the elastic member 4. Keep sealed.

  The flow rate adjusting valve body 5 is integrally provided with a pushing projection (hereinafter referred to as “projection”) 5b. The protrusion 5b passes through the tip opening 2b of the dispensing cylinder 2 and is exposed to the outside. In addition, a plurality of vertical grooves 5c are formed on the outer peripheral wall of the protrusion 5b to form a passage for allowing the inner solution to flow out.

  Further, the flow regulating valve body 5 is formed with an internal passage 5d that communicates with the outside through the tip opening A of the protrusion 5b. In addition, the annular body 5e hangs down from the lower side of the flow rate adjusting valve body 5 and is integrally connected to the elastic member 4 (spring body 4a). In the present embodiment, the flow rate adjusting valve body 5, the elastic member 4, and the push-in protrusion 5b are integrally formed. However, according to the present invention, those formed separately may be combined.

  Furthermore, the flow regulating valve body 5 is provided with a concave member 6 that forms an internal space R between the valve body 5 and the valve body 5. The concave member 6 has a peripheral wall 6a fitted inside the annular body 5e, and the lower end thereof is sealed by the bottom wall 6b. Thereby, when the concave member 6 is fitted to the valve body 5, an internal space R is formed therebetween.

The bottom wall 6 b is formed with a first small hole (hereinafter referred to as “first small hole”) 7 that allows the container opening 20 a to communicate with the internal space R. The first small hole 7 is composed of a small cross-sectional area D ₁ than the cross-sectional area D _r of the internal space R.
