Description

  The present invention relates to a spout that allows the contents in the container to flow out by tilting with the mouth of the container facing downward, or holding the container in an inverted posture and pushing the protrusion of the tip opening. It is intended to prevent the scattering of things.

The spout stopper that discharges the contents in the container by pushing the protrusion protruding from the tip opening will immediately restore the protrusion to the initial position due to the repulsive force of the elastic member when the pushing operation is released. There is an advantage that it can be closed, there is no dripping, and the contents in the container can be avoided as much as possible from the outside air, and it is often used for containers filled with cosmetics and medicines (for example, patent documents) 1).
Utility Model Registration No. 2553493

  By the way, this kind of spout taps out the contents of the container vigorously when the protrusion is pushed in and the tip opening is opened depending on the size of the tip opening, the filling capacity, the type of contents and the application. As a result, the contents may scatter.

  The subject of this invention exists in the place which proposes the pouring tap which can reduce the momentum of the content at the time of outflow.

The present invention is fixedly held at the mouth of the container, and is supported through an elastic member on the inside of the pouring cylinder and the pouring cylinder that causes the contents in the container to flow out to the outside through the opening at the tip. A valve body that abuts on the inner seating surface of the dispensing cylinder and maintains the tip opening in a sealed state, and is connected to the valve body, passes through the tip opening of the dispensing cylinder, and is exposed to the outside. A push projection that opens the tip opening by separating the valve body from the inner seating surface of the extraction cylinder by pushing the exposed portion;
The dispensing cylinder has a peripheral wall fitted to the base inner wall of the elastic member, and an air replacement inner cylinder that connects the internal space of the container and the internal passage of the dispensing cylinder is disposed, Provided on at least one of the wall between the peripheral wall of the inner cylinder and the base inner wall of the elastic member and between the outer wall of the base of the elastic member and the inner wall of the extraction cylinder, and at least one of the opposing wall surfaces The pouring tap is characterized in that a longitudinal groove is provided as a passage for allowing the contents to flow out and reducing the momentum at that time.

  A passage is provided between one or both of the cylindrical body and the base inner side wall of the elastic member, or the base outer side wall of the elastic member and the inner side wall of the outlet cylindrical body constituting the outlet plug, Since the contents are allowed to flow out through the passage, the momentum of the contents is reduced.

  In the initial stage of starting the dispensing of contents with the container tilted or reversed, the contents in the container may flow into the inner cylinder, but this may occur due to air replacement, By this air replacement, the contents in the container are formed either between the peripheral wall of the inner cylinder and the inner wall of the base or between the outer wall of the base of the elastic member and the inner wall of the extraction cylinder. It is smoothly discharged to the outside through the passage.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a sectional view showing an embodiment of a spout according to the present invention.

  In the figure, reference numeral 1 denotes a dispensing cylinder forming the basic skeleton of the dispensing tap. The pouring cylinder 1 has a tapered shape (nozzle shape) whose diameter gradually decreases toward the tip, and an inner passage 1a is formed on the inner side, and the tip is connected to the inner passage 1a. A tip opening 1b through which an object flows out toward the outside is formed.

  Reference numeral 2 denotes a flange integrally provided on the outer wall of the dispensing cylinder 1. The flange 2 abuts against the upper end surface of the mouth of the container and seals between them, and positions the outlet cylinder 1 with respect to the mouth. The lower portion of the flange 2 is the mouth of the container. The extraction cylinder 1 is fixedly held by being fitted to. The dispensing cylinder 1 is illustrated as being fitted and fixed by means such as undercut, but may be fixed by screwing or the like.

  3 is an elastic member (resin spring etc.) arrange | positioned inside the extraction | pouring cylinder 1 (internal channel | path 1a). The elastic member 3 includes a spring body 3a and an annular base 3b that is integrally connected to the spring body 3a and supports the spring body 3a. 4 is a valve body held by the elastic member 3. The valve body 4 abuts against an inner seat surface 1c provided in the internal passage 1a of the dispensing cylinder 1 to maintain the tip opening 1b in a sealed state.

  Reference numeral 5 denotes a protrusion shown as an example integrally connected to the upper end surface of the valve body 4. The projection 5 passes through the tip opening 1b of the dispensing cylinder 1 and is exposed to the outside. As shown in FIG. 2, a plurality of passages for allowing the contents to flow out are formed on the outer peripheral wall. Vertical grooves 5a to 5d are formed.

Reference numeral 6 denotes an inner cylinder disposed inside the dispensing cylinder 1. The inner cylinder 6 is suspended and held on the inner wall of the base 3b of the elastic member 3, and has a passage for replacing air when the contents are discharged. Although the inner cylinder 6 has been shown as an example of a lower annular body 6a having a relatively small opening area and an upper annular body 6b (peripheral wall) having a slightly larger opening area than the lower annular body 6a. There it is also possible to apply the annulus straight all become the same among each other doorway, it is possible to perform efficient replacement of the air by reducing at least the inlet 6a ₁ of the doorway.

A passage 7 connects the internal space of the container and the internal passage 1a of the dispensing cylinder 1 to each other and efficiently flows the contents into the dispensing stopper. This passage 7 is formed by at least one narrow groove (longitudinal groove) 6 c provided on the outer peripheral surface of the inner cylinder 6. The narrow groove 6c can also be provided on the inner wall of the base 3b of the elastic member 3, and in some cases, a narrow groove may be provided on both of them to form the passage 7 (vertically on at least one of the opposing wall surfaces). A groove may be provided). In the illustrated example, the passage 7 is shown as being formed between the inner wall of the base 3b of the elastic member 3 and the peripheral wall of the inner cylinder 6, but the outer wall of the base 3b of the elastic member 3 and the dispensing cylinder 1 are shown. Between the inner wall of the base 3b of the elastic member 3 and the peripheral wall of the inner cylinder 6 and between the outer wall of the base 3b of the elastic member 3 and the extraction cylinder. It can also be formed both between the inner wall of the body 1.

  Further, 8 is a cover cap that is detachably screwed to the mouth of the container and stores the pouring stopper inside. The cover cap 8 is composed of a peripheral wall 8a that surrounds the dispensing cylinder 1, and a top wall 8b that is integrally connected at the upper end of the peripheral wall 8a to form a storage space on the inside thereof. The back surface of the top wall 8b Is provided with a seal cylinder 8c for contacting the distal end surface of the dispensing cylinder 1 and keeping it in a liquid-tight state.

  In order to allow the contents in the container to flow out in the spout configured as described above, the mouth of the container is tilted downward as shown in FIG. 3, or the container itself is inverted as shown in FIG. Then, the protrusion 5 may be directly pressed against the portion where the contents should flow out.

  As a result, the valve body 4 is separated from the inner seating surface 1c of the dispensing cylinder 1, the tip opening 1b is opened, and the content is passed through the passage formed by the longitudinal grooves 5a to 5d under the replacement of air by the inner cylinder 6. Things flow out.

  Since the contents always pass through the passage 7 when the contents flow out, the momentum is always reduced, and at this time, the inner cylinder 6 passes between the dispensing cylinder 1 and the container space. Since the air is exchanged between each other, the contents are efficiently dispensed without causing scattering.

  The elastic member 3 and the valve body 4 can be configured as an integrally molded product of a synthetic resin, thereby reducing the number of parts.

The base 3 b of the elastic member 3 can be sandwiched between the inner wall of the dispensing cylinder 1 and the peripheral wall of the inner cylinder 6, whereby the base 3 b is firmly fixed to the dispensing cylinder 1.

  It is possible to provide a spout that reduces the momentum when the contents flow out and does not cause jumping.

It is the figure which showed embodiment of the pouring tap according to this invention. It is an external appearance perspective view of the structural member integrated in the pouring stopper shown in FIG. It is explanatory drawing of the outflow situation of the content by the pouring tap shown in FIG. It is explanatory drawing of the outflow situation of the content by the pouring tap shown in FIG.
