Description

  The present invention relates to a nozzle head of a manual push-down pump that is assembled to a mouth portion of a container and dispenses the content liquid stored in the container.

For example, Patent Document 1 describes an invention relating to a nozzle head of a manual push-down pump that is assembled to a mouth portion of a container and dispenses the content liquid stored in the container. This nozzle head is used by being closely fitted to the upper end of the pump, and is assembled with a foamed body that stirs the content liquid with air to foam.
Japanese Patent Laid-Open No. 10-296140

  In a dispensing container equipped with a manual push-down pump as described above, the content liquid can be poured out by the action of the pump by pressing the top wall of the nozzle head with a fingertip and pushing down the nozzle head. Since the repulsive force of the spring arranged in the pump acts on the fingertip during the push-down operation, a manual push-down pump should be configured so that the push-down operation can be performed stably regardless of the spring repulsion force. is required.

  Therefore, the technical problem of the present invention is to improve the pressing operability of the nozzle head pressed by the fingertip, particularly by the shape of the top wall of the nozzle head, and to make the shape of this nozzle head hygienic. ,It is in.

Among the means for solving the problems of the present invention, the means of the first invention is:
In the manual depressing pump nozzle head assembled to the mouth of the container,
To form a recess so that a fingertip for pressing fits in the center of the outer surface of the top wall, and to form a drainage groove for escaping water accumulated in the recess from the recess to the periphery is there.

With the above-described configuration of the first aspect of the invention , the nozzle head can be pushed down in a stable state without sliding the fingertip by applying the fingertip to the recess. In particular, when one hand is blocked, the nozzle head is pushed down with the thumb of the other hand while the dispensing container is placed on the table , and the content liquid is poured into the palm of the same hand. In this way, the extraction container is not fixed enough, but by fitting the fingertip of the thumb into the recess, the pump can be pushed down along the axial direction of the pump, and the extraction container is knocked down. The pressing operation can be easily performed with a relatively small force.

In addition, when a concave portion is formed on the outer surface of the top wall, water tends to accumulate in this portion (water drainage worsens), giving a non-hygienic impression, and actually causing mold, etc. However, in the first invention , such a problem can be solved by forming a drainage groove for escaping the water accumulated in the concave portion in the portion from the concave portion to the peripheral edge, and to be used hygienically. Can do.

  The finger to be pressed is an index finger or a thumb depending on the type of the content liquid, the shape of the container, the method of use, and the like. The shape of the recess is a design matter that can be determined according to these modes.

The means of the second invention is the first invention ,
Inclining the base plane of the outer surface of the top wall obliquely downward from the front to the rear,
On the base plane, forming a ridge on the peripheral edge from the vicinity of the side excluding the vicinity of the front to the rear and forming a recess so as to surround the center,
Forming drainage grooves across the ridges located from the center to the rear,
It is in.

The said structure of 2nd invention is an example which showed concretely the shape of a crevice and the formation position of a drain ditch. With the configuration of the second aspect of the invention , the base end plane of the outer surface of the top wall is inclined obliquely downward from the front part toward the rear part, and the ridge part located at the rear part from the vicinity of the central part is traversed. By forming the drainage groove, the water accumulated in the recess can be more efficiently discharged from the top wall outer surface.
In the present invention, the direction in which the nozzle is located is the front part.

Since the present invention has the above-described method and configuration, the following effects can be obtained.
In the first invention , the finger head can be pushed into the recess so that the fingertip does not slip and the nozzle head can be pushed down in a stable state, and the drainage groove is formed. Thus, the water accumulated in the recess can be efficiently discharged from the outer surface of the top wall. In particular, when one hand is closed, pressing and dispensing operations with one hand can be easily and stably performed with a relatively small force.

In the second invention , the base end plane of the outer surface of the top wall is inclined obliquely downward from the front portion toward the rear portion, and the drainage groove traverses the ridge portion located at the rear portion from the central portion. As a result, the water accumulated in the recess can be more efficiently discharged from the outer surface of the top wall.

Embodiments of the present invention will be described below with reference to the drawings.
1 to 4 show a first embodiment of a nozzle head according to the present invention. FIG. 1 is a partial longitudinal sectional view showing a state in which the nozzle head 1 is closely fitted to an upper end portion of a pump 21. FIG. Is a plan view of the nozzle head 1, FIG. 3 is a longitudinal sectional view taken along line AA in FIG. 2, and FIG. 4 is a longitudinal sectional view taken along line BB in FIG.

  The nozzle head 1 of the present embodiment is for foaming and pouring the content liquid. The (nozzle head) main body 1a, the nozzle 11 and the structure thereof are mesh-like, and the ejected content liquid is stirred with air. It consists of three members of the foamed body 12 to be foamed.

  The main body 1a has a double cylindrical shape with a top, and has a shape in which an outer cylinder 14 and an inner cylinder 13 are suspended from the top wall 2. The front half of the upper end portion is formed with an assembly recess 15 that is open toward the front with the outlet plate 16 that is a part of the inner cylinder 13 as a bottom portion. Exit 17 is established.

  The nozzle 11 has a simple cylindrical shape, and is assembled in a posture protruding forward from the main body 1a by closely fitting and assembling the latter half of the nozzle 11 into the assembling recess 15, and a foamed body is formed therein. 12 is disposed. Further, the latter half of the nozzle 11 is inserted to the front of the jet port plate 16 which is the bottom of the mounting recess 15, and the mounting recess 15 between the rear end edge of the nozzle 11 and the jet port plate 16 is inserted. A pair of air holes 18 opened between the inner cylinder 13 and the outer cylinder 14 are formed on both side portions of the peripheral wall portion, that is, on both side portions of the peripheral wall portion of the assembly recess 15 adjacent to the jet port 17. (See Figure 3)

  Next, the base end plane 2b of the outer surface of the top wall 2 of the main body 1a of the nozzle head 1 is formed so as to be inclined obliquely downward from the front portion F where the nozzle 11 is located toward the rear portion B. (Refer to FIG. 3) The ridge portion 3 is formed in the peripheral edge portion (region indicated by the one-dot chain line in FIG. 2) from the vicinity of the side portion S to the rear portion B excluding the vicinity of the front portion F and surrounds the central portion In this way, the recess 4 for fitting the fingertip during pressing is formed. In addition, the height of the protruding portion 3 gradually decreases from the vicinity of the side portion S toward the front portion F and reaches the proximal end plane 2b (see FIG. 3).

  Moreover, the drainage groove 5 is formed so that the bottom part may follow the base end plane 2b inclined so that the protrusion 3 part located in the rear part B may be crossed from the center part. For example, when used in a bathroom or bathroom, water tends to accumulate in the recess 2 formed for finger contact, and it looks bad and has hygiene problems. Water can be discharged naturally.

  Then, the nozzle head 1 is closely fitted to the upper end of the pump 21, and the pump 21 is screwed and assembled to the mouth of the container 24 with the assembly cap 22 (see FIG. 1). Is pushed down so that the fingertip fits into the recess 2, the content liquid is ejected vigorously from the ejection port 17 by the action of the pump 21, and the air is ejected from the inner cylinder 13 and the outer cylinder 14 by the ejection operation of the content liquid Through the space between the air holes 18 and introduced into the assembly recess 15 in a state where the left and right are evenly sucked, and the foamed content liquid is poured out through the foamed body 12 together with the content liquid. It is.

  FIG. 5 is an explanatory view showing a typical example of the usage mode of the dispensing container in which the manual push-down type pump 21 having the nozzle head 1 according to the second embodiment of the present invention is attached to the housing 24. In this state, the pouring container is placed on a table or the like, the outer cylinder 14 of the nozzle head 1 is sandwiched between the index finger and the middle finger of one hand H (right hand in FIG. 5), and the thumb is placed in the recess 4 of the top wall 2. This is a method in which the nozzle head 1 is pushed down while being pushed down, and the content liquid is poured out into the palm of the same hand. For example, when holding an infant with one hand and washing the hair with the other hand, This is a very convenient method of dispensing when the hand is blocked.

  In the case of such a pouring method, since the fixing of the pouring container is not sufficient, the direction of pressing with the thumb tends to shift, and a large force is required for the pressing operation. There was a problem of defeating. Therefore, by forming the recess 4 in the top wall 2 as described above, the thumb can be guided to the center of the top wall 2 without being particularly conscious, and the fingertip of the thumb can be fitted into the recess 4. Now it is possible to place it in the middle and stably down. That is, since the thumb can be surely pushed down along the axial direction of the pump, it is possible to easily perform the pressing operation with a relatively small force without tilting the pouring container.

  As mentioned above, although embodiment of this invention was described along the Example, the aspect of this invention is not limited to these Examples. For example, in the first embodiment, the nozzle head of the type in which the content liquid is foamed and poured out has been described. However, the effect of the shape of the top wall of the nozzle head of the present invention is, of course, In addition, for example, it is generally exhibited in various types of nozzle heads such as a liquid shampoo, a nozzle head for pouring a detergent and the like, and a nozzle head for spraying the content liquid in a mist form. Further, a plurality of drain grooves can be provided, or the nozzle head main body and the nozzle can be integrally formed.

  As described above, the nozzle head of the present invention can be easily and stably carried out with a relatively small force by pushing a finger with a concave portion formed on the top wall and pushing down with one hand, and a dispensing operation. The accumulation of water on the top wall can be prevented, and it can be deployed in a wide range of applications in combination with a manual pump.

It is a partial vertical side view which shows the state which attached the 1st Example of the nozzle head of this invention to the pump. It is a top view of the nozzle head of FIG. It is a longitudinal cross-sectional view shown along the AA line in FIG. It is a longitudinal cross-sectional view shown along the BB line in FIG. It is explanatory drawing which shows an example of the usage condition of the extraction container which attached the pump of the manual depression type which has 2nd Example of the nozzle head of this invention to the housing.
