JP6138707B2 - Pump type dispenser - Google Patents

Description

  The present invention relates to a pump-type dispenser that discharges a content liquid filled in a container toward the outside.

  In containers filled with content liquids such as shampoos, body soaps, hand soaps, face wash, etc., the liquids are suspended from the mouths of the containers, and the liquids are discharged from the nozzle tip openings by pushing down and restoring the nozzle head. Many are equipped with a pump-type dispenser.

  This type of pump-type dispenser, especially a stationary type container, is often used with both hands to push down the nozzle head with one hand and receive the liquid content with the other hand. Depending on the situation, there is a case where the operation can be performed with one hand.

  As such a dispenser, for example, in Patent Document 1, an auxiliary member that exhibits a finger-hooking function in the push-down operation of the pump can be attached to an assembly cap that fixes the manual push-down pump to the mouth tube portion of the container body. A pump dispenser is shown. Since the auxiliary member is provided with an outer plate-like locking plate piece, an index finger or the like can be applied to the lower surface of the locking plate piece when the nozzle head is pushed down with the thumb of one hand. As a result, the position of the palm that receives the content liquid can be stabilized, so that the content liquid can be reliably discharged onto the palm. In addition, since the nozzle head and the locking plate piece can be operated with the thumb and index finger held between them, a pressing force can be effectively applied to the nozzle head.

  By the way, in the pump type extractor of patent document 1, since the number of parts will increase with respect to the conventional extractor which does not have an auxiliary member, the subject remains by the point that cost and used material increase. . In addition, since the locking plate piece always protrudes when the auxiliary member is attached, the locking plate piece is an obstacle for those who are accustomed to the operation of the conventional dispenser having no finger hook function. It is also assumed. In this case, if the auxiliary member is removed, it can be used in the same manner as a conventional container, but it is necessary to secure a place for the removed auxiliary member, and it is necessary to attach the auxiliary member every time it is operated with one hand. It will take time and effort.

  The present invention is intended to solve such problems, the purpose of which can be increased with the provision of a finger-hook function for operation with one hand, the cost and materials used can be suppressed, It is another object of the present invention to provide a new pump-type dispenser that can easily switch the presence / absence of the finger-hook function according to the use situation.

The present invention includes a base cap that is held at the mouth of a container, a pump that is suspended and held at the mouth by the base cap, and that pumps up the liquid contained in the container, and the pump is driven by repeatedly pushing down and restoring. In a pump-type dispenser comprising a nozzle head that discharges the content liquid from the nozzle tip opening,
Provide a lever that is swingably supported on the base cap,
The lever is a pump-type dispenser having a contact portion that presses against the base cap to cause the lever to stop swinging in a posture facing the nozzle.

  It is preferable that the lever is integrally connected to the base cap via a hinge.

  It is preferable that the lever includes an engaged portion that is locked to the engaging portion of the base cap and holds the lever in a posture to face the nozzle.

  The pump type dispenser of the present invention includes a lever supported by a base cap so as to be swingable. This lever presses against the base cap to cause a swing displacement of the lever in a posture facing the nozzle. Since the contact portion to be stopped is provided, it can function as a finger hook when operating the raised lever with one hand. For this reason, if you do not need the finger hook function, use it with the lever tilted, and if you need the finger hook function, such as when you operate it with one hand, use it by raising the lever. You can easily switch between function and non-function.

  When the lever is integrally connected to the base cap via a hinge, the number of parts can be reduced compared to the conventional dispenser with a finger hooking function, thus reducing costs and materials used. It becomes possible to do.

  If the lever is provided with an engaged portion that holds the lever in a posture to be opposed to the nozzle by being engaged with the engaging portion of the base cap, it is not necessary to pull up the lever each time it is operated with one hand. , It improves usability.
