Description

  In the invention of the present application, in order to pour out various liquid substances accommodated in the hollow container, a reciprocating suction pump is attached to the mouth and neck of the liquid container so that the liquid substance inside can be poured out. In particular, a vertical reciprocating liquid dispensing pump suitable for dispensing a high-viscosity solution contained in a hollow container has a jet head that is easy to press. The present invention relates to a liquid dispensing container provided.

  In the case of hollow containers containing solutions such as conventionally used detergents, shampoos, or various liquid cosmetics, the contents can be poured out when it is necessary to take out and use these contents. After opening the lids of various containers in such a state, hold the container in your hand and let the contents flow out while tilting, or hold a flexible liquid container such as synthetic resin in your hand In general, the wall is pressed and the contents are pushed out while being compressed and deformed.

  However, in the case of a container in which the internal solution is poured out by such a method, the container lid must be opened with both hands, and if the container is too large or heavy, In recent years, a container that is equipped with various dispensing devices at the opening of the liquid container so that the contents can be dispensed by the action of the pump, because it feels somewhat inconvenient to dispense, It has come to be used frequently.

  As a dispensing device used for such a liquid container, by moving up and down by an operating member a piston provided inside a cylinder screwed into the mouth neck of the hollow container and suspended in the container, The various solutions contained in the container are sucked into the cylinder via a suction valve provided at the lower end of the cylinder, and the solution is pressurized in the cylinder, so that the injection provided at the upper end of the cylinder Small-sized dispensing pumps configured to dispense from the injection nozzle through the head have come into general use.

  As a general form of a vertical reciprocating pouring pump that has been widely used conventionally, as shown in FIG. 5, a lid 33 screwed into the mouth-neck portion 32a of the container body 32 is suspended in the container. A stem having a cylindrical piston 36a that is provided so that a ball 35a is brought into close contact with a valve seat 35b formed at the lower end portion of the cylinder 35 to be provided, and is fitted in the cylinder so as to be movable up and down. A discharge valve provided so that the bolt 36c is in close contact with a valve seat 36b formed at the upper end of 36 forms a pump body, and at the upper end of the stem 36, a press head 38a and an injection nozzle 37 The piston of the extraction pump 31 configured by fitting and fixing the injection head 38 having the above is discharged by an up and down movement operation.

  To dispense the internal solution by operating the dispensing pump configured as described above, the fingertip and palm should be pressed against the pressure surface of the ejection head and pushed down to move the stem and piston up and down. However, it is general that the pressing surface of the ejection head portion that presses the fingertip or palm is formed into a flat surface having a circular shape, or a surface curved in an upward arc shape.

However, in order to push down the ejection head part during use, it is necessary to apply a force against the air pressure and an elastic member that urges the operating member such as the stem and piston upward, and a little larger in the initial operation. Sometimes pressing force is required or a fingertip is slid.
Therefore, as shown in FIG. 4A, the surface of the pressure head 21a of the ejection head 21 is covered with a soft material 22 such as rubber so that the repulsive force received by the fingertip is softened or prevented from slipping. -1454), and as shown in FIG. 4B, the depression head 26 curved downward is provided on the surface of the pressure head 25a of the ejection head 25 so that the fingertip slips off the pressure surface. Those which have been omitted are proposed in Japanese Utility Model Publication No. 4-15667 and Japanese Utility Model Publication No. 64-29162.
In addition, the dispensing pump having the pressure head portion formed in such a structure can reduce the initial dynamic pressure applied to the fingertip as compared to the conventional one, and can also prevent the fingertip from slipping. However, there is still room for improvement because it cannot be used with one hand and is somewhat inconvenient.

  In order to improve the above-mentioned problems, the present invention applies a fingertip to the pressing surface in a liquid dispensing container equipped with a vertical reciprocating dispensing pump so as to dispense the internal solution. When pushing down the jet head, the feeling of the initial dynamic pressure applied to the fingertip can be eased, and the fingertip can be prevented from slipping from the pressing surface of the jet head. An object of the present invention is to provide a liquid dispensing container having a structure that can be used by dispensing a solution.

  An injection head having a press head and an injection nozzle is fitted and fixed to the stem upper end of an operating member that is mounted on the mouth and neck of the container body and is vertically movable in a cylinder suspended in the container. In the dispensing pump configured to be able to dispense by moving the operating member up and down by pressing the pressing head portion, the thumb abutting on the pressing surface of the pressing head portion is engaged. By forming a recess having an optimal shape and forming the inner solution poured out from the spray nozzle on the palm when the thumb is brought into contact with the recess and the spray head is pushed down, In this way, a liquid pouring container configured to allow the pouring operation of the inner solution is formed.

Since the present invention is configured as described above, it is possible to perform the dispensing operation of the dispensing pump with one hand without causing the fingertip to slide from the pressing surface, thereby reliably dispensing the internal solution onto the palm. Therefore, the other hand can do other things, and a soft material layer is provided on the surface of the engaging concave portion of the thumb formed on the pressing portion of the ejection head, so that the touch feeling can be achieved. In addition, it is possible to prevent the fingertip from becoming painful by weakening the repulsive force of the initial dynamic pressure.
