Description

  The present invention relates to a pump container that can be easily operated with one hand.

  As this type of pump container, there is proposed a hand pump that can be used with one hand in which a hand plate linked to these is provided on the head of the pump or the neck of the pump, and the hand plate is provided below the pump nozzle (for example, a patent Reference 1). In addition, in a liquid dispensing apparatus that is assembled to a mouthpiece of a container for storing liquid and moves up and down a stem having a piston structure at the bottom, the liquid in the container is poured out from the nozzle of the stem. The upper end is bent to the side, and a pressure plate is mounted on the upper end of the stem, and further, the tip nozzle is directed upward and bent toward the center of the pressure plate. There has also been proposed a liquid pouring device for a liquid container characterized by assembling a lead-out tube (see, for example, Patent Documents 2 to 5). Each of these pump containers presses the pressure plate at the tip of the stem with the back of the hand, but unlike the palm, the back of the hand is difficult to apply force and feels pain, especially when the viscosity of the contents increases. May be necessary and may cause pain. In addition, if a strong force is applied with the back of an unfamiliar hand, it is expected that the container will be frequently overturned in a bathroom that is slippery due to excessive force.

  On the other hand, it is also a pump that can be operated with one hand, and is provided at a position where the operator's hand is in a position where the contents discharged from the nozzle can be received, using the principle of spear An operation lever comprising: an operating portion that is provided; an action portion that pushes down the push-down portion by a pressing force by the pressing operation; a fulcrum portion having a support shaft portion that is an operation center; and a fixing portion that is disposed on the cap. In addition, a dispenser characterized in that a fixed support portion including a support portion that supports the fulcrum portion of the operation lever is provided, and the cap and the fixed portion are integrated (for example, a patent document). 6). However, this is a structure in which the vicinity of the nozzle is pressed with one thumb, and although it uses the principle of heels, it places a considerable burden on the thumb, especially when the contents are highly viscous, and it is expected to be difficult to operate. Is done. Further, the tip of the nozzle is likely to come into contact with the palm, and the nozzle may become dirty or clogged, which may cause sanitary problems. Furthermore, in such a structure, you must adjust the angle of the palm other than the thumb yourself and receive the contents well, but if you are not used to it, it will be difficult to operate and you will probably drop the contents on the floor Be done

  Similarly, using the principle of scissors, an assembly piece to be assembled to the mounting cap of the pump, a support column extending upward from the assembly piece, and a pivotal attachment to the upper part of the support column, The operating arm extends over the top of the head, a push bar directed from the operating arm to the top surface of the head, and a connecting tube that fits into the discharge port and opens at the tip of the operating arm. There has also been proposed a container with a pump provided with an operation mechanism in which a push-down bar pushes down the head when the tip is pulled down, and the content liquid is poured out from the opening of the connecting pipe (see, for example, Patent Document 7). This is different from the operation with one thumb as in the above-mentioned Patent Document 6, and conversely, the operation is performed by pulling down with four fingers other than the thumb, and the operability is high when the viscosity of the contents is high. However, it is necessary to hold the tip of the operation arm well so that the nozzle is positioned between the middle finger and the ring finger while keeping the palm up, and it is definitely necessary to pull it down downward. If you pull the operation arm toward you, the container may fall down. Further, as in the case of Patent Document 6, the tip of the nozzle is likely to come into contact with the palm, which may cause similar sanitary problems.
