Description

  The present invention relates to a pressing head used for, for example, a discharger.

2. Description of the Related Art Conventionally, as a discharger, a pump having a pushable stem that stands up in an upward biased state, and a pressing head that has a nozzle having a nozzle hole for discharging contents and is attached to the stem are provided. The configuration is known.
With this dispenser attached to the mouth of the container containing the contents, the contents in the container are transferred by depressing the pressing head and moving the stem downward to operate the pump. The ink is discharged from the nozzle hole through the nozzle.

  However, in this type of dispenser, the content remains in the nozzle after solidification and solidifies, and then, when the content is ejected, it is scattered due to the influence of the already solidified content. there were.

Therefore, a pressing head for solving such a problem is known (see Patent Document 1). The pressing head includes a pressing portion attached to the upper end portion of a pushable stem that stands up in an upward biased state, a nozzle projecting forward from the pressing portion, and having a nozzle hole formed at the front end. And a plug member (hereinafter referred to as a nozzle cover) detachably attached to the front end portion of the nozzle.
The nozzle cover is a cap body that can be removed by being pulled out of the nozzle. The nozzle cover is connected to the pressing portion via a flexible connecting band, and is configured not to be separated from the pressing portion even when it is detached from the nozzle.

For this reason, the contents remaining in the nozzle are difficult to solidify.

JP 2003-292018 A

However, even with the above-described pressing head, it is not possible to completely suppress the entry of outside air or the like into the nozzle, so that the contents may still solidify in the nozzle. As a result, the newly ejected contents are affected by the solidified contents, and the problem of scattering still remains.
Furthermore, it is necessary to remove the nozzle cover from the nozzle every time the contents are discharged, and to attach the nozzle cover again after use. Therefore, it takes time and effort to remove and install the nozzle cover every time, and there is a problem that the operability is poor.

  The present invention has been made in view of such circumstances, and can discharge the contents without deteriorating the operability, and discharge while suppressing the scattering of the contents effectively. It is to provide a pressing head that can be used.

It is characterized by being open.

  In the pressing head configured as described above, the nozzle hole is opened forward while the nozzle cover is attached to the nozzle. Therefore, even when the nozzle cover is still attached to the nozzle, the contents can be discharged by pressing the pressing portion. Therefore, since the trouble of removing the nozzle cover as in the prior art is unnecessary, the contents can be discharged without deteriorating operability.

  Further, when the nozzle cover is attached to the nozzle, the nozzle cover extends forward from the nozzle hole. For this reason, even if there is a solidified content in the nozzle and the newly ejected content is ejected from the nozzle hole while being affected by the solidified content, the nozzle cover prevents scattering. Therefore, it is possible to perform ejection while effectively suppressing scattering.

Moreover, although the nozzle hole is opened, the nozzle cover extends forward from the nozzle hole, so that a part of the air flow flowing from the nozzle hole into the nozzle can be blocked. Therefore, it becomes difficult to dry the inside of the nozzle, and the progress until the content remaining in the nozzle is solidified can be slowed.
Furthermore, depending on the situation, the solidified contents in the nozzle may be removed by washing or the like. At this time, the nozzle cover can be rotated around the hinge and detached from the nozzle. Therefore, the removal operation can be performed efficiently without being obstructed by the nozzle cover.

It is locked to hold the nozzle. Thereby, the nozzle cover is fixed at a position where it is detached from the nozzle.
Further, when the nozzle cover detached from the nozzle is rotated around the hinge, the pair of locking portions are released from the nozzle, the locking of the nozzle cover is released, and the nozzle cover is attached to the nozzle.

(4) In the pressing head according to the present invention, as the locking means, a step is formed on the outer surface of the nozzle so as to descend from the rear side of the nozzle toward the front side. The nozzle cover is attached to the front side of the step, and the base end of the nozzle cover is able to get over the step as the nozzle cover rotates, and the nozzle cover is detached from the nozzle. It is preferable that the nozzle is locked to a portion on the rear side of the step.

O and the surface including the central axis L of the nozzle 3).

  The side plate portions 41 are plate portions that are arranged perpendicular to the upper plate portion 40, and are suspended from both side ends of the upper plate portion 40. The side plate portions 41 on both sides are disposed to face each other, and the nozzle 3 is disposed between the side plate portions 41 on both sides. Locking portions 42 are respectively provided at the base end portions of the side plate portions 41 on both sides, and the position where the nozzle cover 4 is detached from the nozzle 3 by the pair of locking portions 42 on both sides (shown in FIG. 4). A locking means for locking the nozzle cover 4 is configured.

  More specifically, the locking portion 42 is separated from the nozzle 3 in a state where the nozzle cover 4 is attached to the nozzle 3 (the state shown in FIG. 1), and the nozzle cover 4 is detached from the nozzle 3 (FIG. 4). In the state shown in FIG. 2, the rectangular plate piece is engaged with the outer peripheral surface of the nozzle 3. The locking portion 42 protrudes from the base end of the side plate portion 41 and protrudes toward the inside of the opening 22. Further, the locking portions 42 are provided on the side plate portions 41 on both sides, and the pair of locking portions 42 on both sides are disposed to face each other and the side wall portion 22a of the opening 22 described above. It is arrange | positioned along the inner surface (surface mutually opposed). 3 and FIG. 4, the nozzle 3 is clamped from both sides when the nozzle cover 4 is detached from the nozzle 3 as shown in FIGS. 3 and 4, and the rotation operation of the nozzle cover 4 with respect to the nozzle 3 is restricted. Is done.

  A plurality of substantially hemispherical protrusions 42 a are formed on the inner surface of the locking portion 42 (surfaces facing each other). The plurality of protrusions 42a are juxtaposed along the axial direction in a posture (shown in FIG. 1) in which the nozzle cover 4 is attached to the nozzle 3, and a posture in which the nozzle cover 4 is detached from the nozzle 3 (FIG. 4). 2), the plurality of protrusions 42a are engaged with the outer peripheral surface of the nozzle 3, respectively.

On the outer surface of the locking portion 42 (the surface facing the side wall portion 22a of the opening 22), an engaging convex portion 42b is formed. The engaging convex portion 42b extends along the axial direction in a posture in which the nozzle cover 4 is attached to the nozzle 3, and is undercut fitted to the engaging convex portion 22c of the side wall portion 22a. .

  Next, the operation of the pressing head 1 having the above configuration will be described.

  First, when the pressing head 1 (discharger 10) is not used, as shown in FIGS. 1 and 2, the engaging convex portion 42b on the outer surface of the locking portion 42 is engaged with the engaging convex portion on the side wall portion 22a of the opening portion 22. Since the undercut fitting to 22c is performed, the upward rotation around the hinge 5 of the nozzle cover 4 is restricted, and the nozzle cover 4 is held in a state of being attached to the nozzle 3.

  In a state before use such as when a product is transported or displayed, the male screw 23 of the communication cylinder portion 21 is screwed to a female screw (not shown) of the head holding portion 13 and the pressing head 1 is pushed down. Is retained. This prevents the pressing head 1 from being inadvertently operated and discharging the contents. At this time, the communicating tube portion 21 is screwed into the head holding portion 13 until the lower end of the convex rib 24 provided on the communicating tube portion 21 is locked to the upper surface of the head holding portion 13. Thereby, since the pressing head 1 is arrange | positioned in a predetermined height position, the height dimension of the several discharger 10 can be arrange | equalized.

Next, the case where the pressing head 1 (discharger 10) is used will be described.
First, in a state where the nozzle cover 4 is attached to the nozzle 3, the nozzle hole 3a is opened forward. Therefore, even when the nozzle cover 4 remains attached to the nozzle 3, the contents can be discharged by pressing the pressing portion 2.
The discharge operation of the contents will be described in detail. The upper surface of the top wall portion 20a of the outer shell portion 20 of the pressing portion 2 is pressed with a finger or the like to press the pressing portion 2 along the axial direction. Press down. As a result, the contents in the container (not shown) flow into the communicating cylinder part 21 through the stem 11 by the pump 14 and flow into the nozzle 3 from the communicating cylinder part 21. As a result, the contents can be discharged from the nozzle hole 3a.
In particular, unlike the conventional pressing head, which requires time and effort to remove the nozzle cover each time it is discharged, the nozzle cover 4 can be left attached, so that the contents can be discharged without deteriorating the operability. Can do.

  Further, when the nozzle cover 4 is attached to the nozzle 3, the nozzle cover 4 extends forward from the nozzle hole 3a. Therefore, even if there is a solidified content in the nozzle 3 and the newly discharged content is discharged from the nozzle hole 3a while being affected by the solidified content, the nozzle cover 4 prevents scattering. Is done. Thus, even if there is a solidified content in the nozzle 3, it is possible to discharge while effectively suppressing scattering.

  Moreover, although the nozzle hole 3a is opened, the nozzle cover 4 extends forward from the nozzle hole 3a, so that part of the flow of air flowing from the nozzle hole 3a into the nozzle 3 is blocked. Can do. Therefore, drying in the nozzle 3 can be suppressed, and the progress until the contents remaining in the nozzle 3 solidify can be delayed.

Furthermore, the solidified contents in the nozzle 3 may be removed by washing or the like depending on the situation. At this time, the nozzle cover 4 can be rotated around the hinge 5 to be detached from the nozzle 3. Therefore, the removal operation can be performed efficiently without being obstructed by the nozzle cover 4.
Here, the above-described detaching operation of the nozzle cover 4 will be described in detail. First, the nozzle cover 4 attached to the nozzle 3 is pushed upward. Thereby, the engaging convex part 42 b on the outer surface of the locking part 42 is disengaged from the engaging convex part 22 c of the side wall part 22 a of the opening 22, and the nozzle cover 4 can be rotated around the hinge 5.

  Subsequently, as shown in FIGS. 3 and 4, the nozzle cover 4 described above is rotated upward around the hinge 5, and the nozzle cover 4 is detached from the nozzle 3. At this time, the pair of locking portions 42 provided on the nozzle cover 4 are locked to the outer peripheral surface of the nozzle 3 to sandwich the nozzle 3. As a result, the nozzle cover 4 is fixed at a position separated from the nozzle 3 while maintaining a substantially vertical posture. That is, since there is a locking position by the pair of locking portions 42 (locking means) on the trajectory of the rotation operation of the nozzle cover 4, the nozzle cover 4 is engaged with the pair of engagement by the operation of detaching the nozzle cover 4 from the nozzle 3. It is fixed by the stopper 42. Since the plurality of protrusions 42 a are formed on the inner surface of the locking portion 42 described above, the locking portion 42 is reliably locked to the outer peripheral surface of the nozzle 3.

  Accordingly, the nozzle cover 4 can be fixed at the position where it is detached. Therefore, when the content solidified in the nozzle 3 is removed by washing or the like, the nozzle cover 4 can be kept in a detached state. Therefore, the removal operation can be performed very efficiently.

  In addition, after the operation of removing the solidified contents is completed, the nozzle cover 4 in a posture standing substantially vertically is pressed and tilted forward, and the nozzle cover 4 is rotated downward around the hinge 5. Thereby, after the pair of locking portions 42 are detached from the nozzle 3 and the locking of the nozzle cover 4 is released, the nozzle cover 4 is directly attached to the nozzle 3. That is, since there is a locking position by the pair of locking portions 42 (locking means) on the trajectory of the rotation operation of the nozzle cover 4, the nozzle cover is moved by the operation of releasing the locking of the nozzle cover 4 by the locking portion 42. 4 is attached to the nozzle 3. At this time, the engaging convex portion 42 b on the outer surface of the locking portion 42 is undercut fitted to the engaging convex portion 22 c of the side wall portion 22 a of the opening 22. Thereby, the upward rotation around the hinge 5 of the nozzle cover 4 is restricted, and the nozzle cover 4 is held in a state of being attached to the nozzle 3.

According to the pressing head 1 described above, the pressing portion 2 can be pushed in and the contents can be discharged while the nozzle cover 4 is still attached to the nozzle 3, so that the operability is not deteriorated. Smooth discharge work can be performed.
Further, since the nozzle cover 4 extends from the front of the nozzle hole 3a, even if there is a solidified content in the nozzle 3, it is possible to discharge while effectively suppressing scattering. it can. Furthermore, since the nozzle cover 4 can be rotated around the hinge 5 to be detached from the nozzle 3, the removal operation can be performed efficiently without being obstructed by the nozzle cover 4.

  In the pressing head 1 described above, since the nozzle cover 4 is provided with a pair of locking portions 42 that sandwich the nozzle 3 when the nozzle cover 4 is detached from the nozzle 3 as the locking means, the nozzle cover 4 The nozzle cover 4 can be more reliably fixed simultaneously with the operation of separating the nozzle 3 from the nozzle 3.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS.
In addition, about the structure similar to 1st Embodiment mentioned above, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As shown in FIGS. 5 and 6, a step 130 is formed on the upper surface of the nozzle 103 so as to descend from the base end side (rear side) of the nozzle 103 toward the front end side (front side). More specifically, the base end portion (nozzle base end portion 131) of the nozzle 103 is a cylindrical tube portion, and the base end of the nozzle base end portion 131 is communicated with the communication tube portion 21. Further, the tip end portion (nozzle tip portion 132) of the nozzle 103 in which the nozzle hole 103a is formed is a cylindrical portion having an outer peripheral surface formed in a flat shape, and the inner peripheral surface is the same as that of the nozzle base end portion 131. It has a circular shape. A step 130 rising along the radial direction of the nozzle 103 is formed between the upper surface of the nozzle base end portion 131 and the upper surface of the nozzle tip end portion 132.

  The nozzle cover 104 is a cover that extends forward with respect to the nozzle hole 103a and opens the nozzle hole 103a forward with respect to the step 130 when attached to the nozzle 103. Are combined. More specifically, the nozzle cover 104 is a cover in which the tip side and the lower side of the nozzle tip part 132 are opened to cover the upper side and both side sides of the nozzle tip part 132, respectively. An upper plate portion 140 disposed above 132 and side plate portions 141 disposed on both sides of the nozzle tip portion 132 are provided.

  The upper plate portion 140 is a plate portion that extends radially outward from the tip of the step 130 and extends to the tip of the nozzle 103. The base end portion of the upper plate portion 140 is locked to the step 130 described above. The side plate portion 141 is a plate portion that is disposed perpendicular to the upper plate portion 140 and is suspended from both side ends of the upper plate portion 140. The side plate portions 141 on both sides are disposed to face each other, and the nozzle 103 is disposed between the side plate portions 141 on both sides.

  The nozzle cover 104 described above is integrally connected to the nozzle 103 via a hinge 105 and is rotatable around the hinge 105. More specifically, the base end portion of the upper plate portion 140 is integrally connected to the nozzle 103 via hinges 105 disposed on both sides of the nozzle 103, and the pressing portion 2, the nozzle 103, and the nozzle cover 104 described above. Are integrally formed.

  The hinge 105 is a strip-shaped connecting piece laid between the base end portion of the upper plate portion 140 and the outer peripheral surface of the nozzle base end portion 131, and one end of the hinge 105 is connected to the base end portion of the upper plate portion 140. The other end of the hinge 105 is connected to the outer peripheral surface of the nozzle base end portion 131. The hinges 105 are respectively disposed on both sides of the nozzle base end portion 131, and the nozzle cover 104 is rotatably supported through a pair of hinges 105 on both sides. A bent portion 150 is formed at an intermediate portion of the hinge 105. When the nozzle cover 104 is attached to the nozzle 103, the bent portion 150 is bent.

  Next, the operation of the pressing head 1 having the above configuration will be described.

  Even in the case of the present embodiment, since the nozzle hole 103a is opened forward when the nozzle cover 104 is attached to the nozzle 103, the nozzle cover 104 is attached to the nozzle 103. The pressing unit 2 can be pushed in while being attached, and the contents can be discharged.

  Further, when the nozzle cover 104 is attached to the nozzle 103, the nozzle cover 104 extends forward from the nozzle hole 103a. Therefore, as in the first embodiment, there is temporarily solidified content in the nozzle 103, and the newly ejected content is ejected from the nozzle hole 103a while being affected by the solidified content. However, the nozzle cover 104 can prevent scattering. Therefore, it is possible to perform ejection while effectively suppressing scattering.

  Further, since the nozzle cover 104 extends forward from the nozzle hole 103a and can partially block the flow of air flowing from the nozzle hole 103a into the nozzle 103, drying in the nozzle 103 can be suppressed, It is possible to slow down the progress until the content remaining in the nozzle 103 solidifies.

Here, when the content solidified in the nozzle 103 is removed by washing or the like, the nozzle cover 104 is rotated upward around the hinge 105 as shown in FIG. As a result, the base end of the nozzle cover 104 (upper plate portion 140) gets over the step 130, the nozzle cover 104 is detached from the nozzle 103, and the base end of the nozzle cover 104 is locked to the upper surface of the nozzle base end portion 131. Then, the nozzle cover 104 is fixed at a position where it is detached from the nozzle 103.
As a result, the nozzle cover 104 can be kept in a detached state, so that the operation of removing the solidified contents can be performed very efficiently.

  In addition, after the operation of removing the solidified contents is completed, the nozzle cover 104 is pressed forward and tilted, and the nozzle cover 104 is rotated downward around the hinge 105. Thereby, after the base end of the nozzle cover 104 is removed from the upper surface of the nozzle base end portion 131 and the locking of the nozzle cover 104 is released, the nozzle cover 104 is directly attached to the nozzle tip end portion 132.

  According to the pressing head 1 described above, the step 130 is formed on the nozzle cover 104 as the locking means, and the base end of the nozzle cover 104 is locked to the upper surface of the nozzle tip portion 132. The nozzle cover 104 can be easily fixed at the same time as the operation of removing the nozzle cover 104 from the nozzle 103.
