Description

  The present invention relates to a spout attached to the mouth of a container, and aims to reduce the number of parts and simplify the assembly work.

In recent years, the spout plug attached to the mouth of a container has been used in order to prevent unauthorized opening and to prevent a large amount of contents from flowing out by adding a flow control function and to avoid splashing at the time of opening. And edible oil, soy sauce, beverages, and other containers (see Patent Document 1).
Utility Model Registration No. 2548506

  By the way, the conventional pouring tap has a complicated structure and tends to increase the number of parts, and the production cost cannot be avoided.

  The subject of this invention exists in the place which proposes the novel extraction tap which can aim at reduction of manufacturing cost by implement | achieving simple assembly while reducing the number of parts.

The present invention has a base that has an opening connected to the inside of the container and is fitted and held in the mouth of the container, and is connected to the base through a hinge so as to be reversible. And a closing plate for sealing the opening of the base,
The closing plate is provided with a pouring opening or a pouring nozzle for pouring the contents in the container,
The outlet plug is formed by integrally forming a buffer wall for adjusting the outlet flow rate of the contents on the base.

  In addition, the present invention has a base that has an opening connected to the inside of the container and is fitted and held in the mouth of the container, and is connected to the base through a hinge so as to be reversible. A closing plate that seals the opening of the base by operation, and the closing plate is provided with a pouring opening or a pouring nozzle for pouring the contents, and when the contents are poured into the base separately from the opening A pouring plug is formed by integrally forming a hole for replacing air, and a buffer wall for adjusting the pouring flow rate of contents can be integrally formed in the base opening.

  In the pouring tap configured as described above, it is preferable that the pouring opening is formed by tearing along a planned fracture line of the closing plate by the pull ring.

  The buffer wall can be formed of a mesh.

  Since the base and the closing plate are connected via a hinge, the pouring tap can be configured with only one part.

  The assembly of the spout is only required by reversing the closing plate from the hinge and fastening the swinging end of the closing plate to the base using an engaging means such as an undercut. It does not take.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a cross-sectional view of the pouring tap according to the present invention before assembly, and FIG. 2 is a cross-sectional view of a state where the spout is attached to the mouth of the container.

  Reference numeral 1 in FIGS. 1 and 2 denotes a base that is fitted and held at the mouth of the container by undercut (or screw) engagement. The base 1 has an opening 1a connected to the inside of the container. At the upper part of the opening 1a, a protruding portion, which is engaged with an undercut of a bulging portion of a leg portion 2a described later, is formed annularly or intermittently so as to extend in the circumferential direction.

  Reference numeral 2 denotes a closing plate shown in the example having a dispensing cylinder. The closing plate 2 is integrally connected to the base 1 via a hinge h, and the leg 2a that is suspended from the closing plate by reversing the closing plate 2 with the hinge h as a base point is used as the opening 1a of the base 1. The opening 1a is sealed by engaging with an undercut at the inner wall portion. The upper leg portion 2a may be formed in an annular shape, or may be formed with a slit or the like in the vertical direction so as to facilitate elastic deformation of the leg portion 2a.

  Reference numeral 3 denotes a pull ring formed on a support column provided on the top surface of the closing plate 2 on the inner side of the dispensing cylinder. Is pulled out by a pull ring 3 to form a pouring opening.

  Further, 4 is a buffer wall provided integrally with the base 1. The buffer wall 4 is provided with a plurality of holes (mesh) 4a, and the content in the container passes through the buffer wall 4 to adjust the flow rate (decrease the dispensing speed) so that it flows smoothly. And prevents splashing of the contents when opened.

  The pouring stopper having the above-described configuration can be integrally formed using a single mold except for the cover cap 5, and the number of parts can be reduced.

  The assembly of the spout is only required by reversing the closing plate 2 with the hinge h as a starting point and fixing its swinging end to the base 1 by means of heat fusion, undercut or adhesive. Manufacturing becomes possible (the part of the hinge h can also be heat-sealed).

  FIG. 3 shows a state in which the contents in the container are being poured out through the dispensing opening.

  FIG. 4 is an external perspective view of another embodiment of the spout according to the present invention. In the above example, the structure in which the extraction opening is formed by tearing off the closing plate 2 with the pull ring 3 is shown. However, in the present invention, the discharging nozzle 6 integrated with the closing plate 2 is shown as shown in the figure. You may make it provide.

  As shown in FIG. 5, for the container filled with a relatively low viscosity such as Worcester sauce as the contents to be filled in the container, an opening 7 for passing the contents and a cylinder (hole) 8 for air replacement are provided. Also in this case, integration with the base 1 is possible. Further, the buffer wall 4 as shown in FIGS. 1 to 3 can be integrally formed in the opening 7.

  6 and 7 show another embodiment relating to the buffer wall 4.

  In the embodiment shown in FIG. 6, a side wall portion 9 having a diameter decreasing downward from the bottom of the opening 1 a of the base 1 is formed, a bottom wall portion 10 is provided at the lower end of the side wall portion 9, and the contents circulate in the side wall portion 9. A plurality of openings 9a are formed. The pouring tap of this configuration prevents the contents from jumping when the flow rate is adjusted and opened by making the contents abut against the bottom wall portion 10 when the contents are poured and bypassing to the side wall portion 9 side.

  The embodiment of FIG. 7 has a structure in which a plurality of fins 11 extending obliquely downward from the opening 1a of the base 1 are formed, and the contents are poured out through the gaps between the fins 11, and such a configuration is adopted. This also prevents the contents from jumping when adjusting the flow rate and opening.

  The flow rate adjusting mechanism is not limited to each of the above-described embodiments, and it is possible to adopt each known structure, and does not hinder the provision of the air replacement cylinder 8 shown in FIG.

  It is possible to provide an easy-to-assemble spout with fewer parts.

It is the figure which showed embodiment of the pouring tap according to this invention. It is the figure which showed the state which mounted | wore the opening part of the container with the pouring stopper shown in FIG. It is the figure which showed the state which is pouring out the content using the pouring tap shown in FIG. It is the figure which showed other embodiment of the pouring tap according to this invention. It is the figure which showed other embodiment of the pouring tap according to this invention. It is the figure which showed other embodiment of the buffer wall formed in the pouring tap according to this invention. It is the figure which showed other embodiment of the buffer wall formed in the pouring stopper according to this invention.
