Description

  The present invention provides a liquid dispensing container, and in particular, a wide range of stable liquid flow regulation according to the liquid properties and the amount of liquid dispensed, with a high degree of freedom regarding the cross-sectional shape and flow channel shape of the flow regulating flow passage for regulating liquid flow. It is related with the liquid extraction container which can perform.

A handy plastic container that contains liquid contents such as seasonings and salad dressings, and the body of the container body is configured to be elastically squeezable, with a nozzle standing at the neck through the shoulder. Types of plastic liquid dispensing containers are widely used.
As such a container, it has a squeezable body (4) so that a small amount can be stably dispensed during liquid pouring, and a cylindrical nozzle (6) on the mouth and neck (5). And a rod-shaped plug (9) whose outer peripheral portion is in close contact with the inner peripheral portion of the nozzle (6) are attached to the nozzle (6) while being urged toward the spout (8) side.

JP 2004-331103 A

In the case of the above-mentioned container with a spout, the flow path diameter of the liquid flow path (a) is extremely small with respect to the inner diameter of the nozzle (6), so that the liquid flow flowing from the inside of the container to the spout (8) of the mouth neck (5) It regulates suitably, and, thereby, a small amount of liquid can be stably dispensed. In addition, the liquid can be prevented from being ejected (scattered) from the nozzle.
By the way, the liquid flow path (a) for regulating the liquid flow is formed by the outer peripheral surface of the rod-shaped plug (9) abutting on the inner peripheral surface of the nozzle (6).
Therefore, the internal shape of the nozzle (6) needs to be a reverse trumpet shape (tapered shape) so as to have a reduced diameter portion. Thus, in the case of the above-mentioned container with a pouring stopper, the internal shape of the nozzle (6) and the external shape of the rod-like plug (9) are in a mutually dependent relationship, and the liquid flow path (a It is difficult to freely set the cross-sectional shape and flow channel shape of (), and therefore there is room for further improvement in the regulation of liquid flow.
Therefore, the present invention has been made in view of the above-described problems of the prior art, and has a high degree of freedom with respect to the cross-sectional shape and the flow channel shape of the flow restricting flow channel that regulates the liquid flow, and the liquid property and liquid dispensing. An object of the present invention is to provide a liquid dispensing container capable of performing a wide and stable liquid flow regulation according to the amount.

A first means according to the present invention for solving the above technical problem includes: a container body having a body part; a nozzle part standing on the mouth-neck part of the container body; and a nozzle body outlet part of the nozzle part A liquid dispensing container having a cap portion for closing the cap,
A plurality of flow restricting plates having a through hole and a notch groove communicating with the through hole on the surface are assembled in multiple stages below the nozzle main body inlet of the nozzle portion.

In the above configuration, the flow restriction channel for restricting the flow of the liquid can be suitably formed by combining the flow restriction plates in multiple stages. That is, in two adjacent flow restriction plates, the notch groove forms the “flow path” of the flow restriction flow path, and the through hole is adjacent to the “inlet part” and “exit part” of the “flow path”. Each “relay part” connecting the “flow paths” can be formed. In addition, since the through hole and the notch groove have a simple structure formed on the plate surface, the hole position / shape and hole diameter of the through hole can be freely set, and the depth of the notch groove can be set. Also, the cross-sectional shape of the groove can be freely set. In this way, by combining the flow restriction plates in multiple stages, the cross-sectional shape and flow path shape of the flow restriction flow channel can be set freely to some extent. Note that the length of the flow restriction channel can be freely set by changing the number of stages of the flow restriction plate.
Therefore, by using the flow restricting plate, the flow restricting flow passage has a high degree of freedom with respect to the cross-sectional shape, flow passage shape and length, and as a result, according to the liquid properties and the amount of liquid dispensed. A wide range of liquid flow regulation can be performed.

  The second means according to the present invention is that a protruding rib is provided on a surface of the leading flow regulating plate facing the nozzle body inlet portion of the plurality of flow regulating plates.

  In the above configuration, the through hole as the “exit part” of the flow restricting channel is preferably prevented from being blocked by the nozzle body inlet, and the gap (flow channel) through which the liquid flowing out of the through hole flows is preferably provided. To secure.

  The third means according to the present invention is that the through hole is provided eccentrically with respect to the central axis.

  In the above configuration, the through-holes are eccentrically provided, and by appropriately setting the positional relationship and the vertical positional relationship of the holes of the adjacent flow-regulating plates, the shape of the flow-regulating flow channel is set as described later. Can be bent into a crank shape.

  The 4th means which concerns on this invention exists in the said notch groove being provided along the major axis of the said flow control board.

  In the above configuration, it is possible to ensure a long flow path length per stage of the flow restriction flow path, and accordingly, it is possible to lengthen the flow path length of the entire flow restriction flow path.

  The fifth means according to the present invention resides in that the two adjacent flow restricting plates are coupled by a fitting pin and a fitting hole.

  In the above configuration, the fitting pin and the fitting hole serve as positioning guides for the positional relationship and the vertical positional relationship of the holes of the adjacent flow restriction plates. Also, it can be a coupling means for tightly coupling two adjacent flow restriction plates.

  The sixth means according to the present invention resides in that two adjacent flow restricting plates are coupled by a hinge portion.

  In the above configuration, when the hole positional relationship of the through holes and the vertical positional relationship of the notch grooves are positioned in advance and the respective flow restricting plates are coupled by the hinge portion, one of the flow restricting plates is folded back with respect to the hinge portion and the other By sequentially assembling the two flow restricting plates, it is possible to connect two adjacent flow restricting plates in the correct hole positional relationship and vertical positional relationship. That is, the above configuration eliminates the need for hole positioning and vertical positioning work, and allows the flow regulating plate to be easily assembled in multiple stages with the correct positional relationship.

  The seventh means according to the present invention is that the nozzle portion has a multi-stage hollow cylindrical shape whose diameter is reduced stepwise toward the outlet portion of the nozzle body.

  In the above configuration, it is possible to suitably secure a sufficient space for stably storing the flow restricting plate inside the nozzle portion while securing the fitting portion and the cap mounting portion for the container main body.

  The eighth means according to the present invention is that the flow restricting plate is accommodated in a hollow cylindrical flow restricting plate accommodating portion that is continuous with the inlet portion of the nozzle body.

  In the above configuration, a plurality of flow restricting plates assembled in multiple stages can be separately provided in the vicinity of the nozzle body.

  According to a ninth means of the present invention, the flow regulating plate storage portion forms a reduced diameter portion at an end opposite to the nozzle body.

  With the above configuration, a plurality of flow restriction plates assembled in multiple stages can be stably attached to the storage portion.

According to the liquid dispensing container of the present invention, the flow restriction plate having a through hole and a notch groove communicating therewith on the surface is assembled in a multistage manner below the inlet portion of the nozzle body, so that the cross-sectional shape and flow channel shape can be reduced. A flow restriction channel having a high degree of freedom can be suitably formed. That is, the inlet portion, the outlet portion, and the relay portion of the flow restriction channel are formed by through holes, while the flow restriction passage is formed by a notch. The through hole and the notch groove are a simple configuration formed on the plate surface, and the flow regulating plate is provided separately in the vicinity of the nozzle body (because it does not need to be provided inside the nozzle body), The hole position / shape and hole diameter of the through hole can be set freely, and the depth of the notch groove and the cross-sectional shape of the groove can also be set freely. Therefore, by setting the hole positional relationship and the vertical positional relationship of adjacent flow restriction plates appropriately and assembling in multiple stages, the flow restriction flow passage has a high degree of freedom with respect to the cross-sectional shape, flow passage shape and length. As a result, a wide range of liquid flow regulation can be performed according to the properties of the liquid and the amount of liquid dispensed. Furthermore, it is possible to suitably suppress the liquid outflow (scattering).
In addition, when the hole positional relationship of the through holes and the vertical positional relationship of the notch grooves are positioned in advance and the flow restricting plates are coupled by the hinge portions, they can be easily assembled in multiple stages.

The flow restricting plate accommodating portion 23 enables the flow restricting plates 40 and 40 to be provided in the vicinity of the inlet portion IN of the nozzle body 24 without being fitted into the nozzle body 24. As a result, the properties of the liquid and the liquid It is possible to suitably regulate the flow of the liquid according to the amount of the liquid dispensed.

  The nozzle body 24 has a divergent shape (trumpet shape) in this embodiment, but may have a tapered shape (reverse trumpet shape) or a straight pipe shape (straight pipe shape). Further, the outlet portion OUT of the nozzle body 24 has a shape that curls downward while expanding outward in order to prevent liquid adhesion to the outer peripheral surface of the nozzle body 24.

  On the inner peripheral surface of the side wall of the cap portion 30, a female screw portion 31 that is screw-coupled with the male screw portion 22a of the nozzle portion 20 is formed. On the inner peripheral surface of the top wall, a rod-shaped plug portion 32 is vertically formed. As the cap portion 30 is fastened to the nozzle portion 20, the rod-shaped plug portion 32 is pushed into the nozzle body 24 of the nozzle portion 20. The outlet portion OUT is configured to be watertightly closed.
