Description

  The present invention relates to a nozzle head of a pump that is assembled to a top tube portion of a container main body containing a content liquid and discharges the content liquid by a push-down operation, and more specifically, a pump that exhibits a virgin function. This relates to the nozzle head.

  Shampoos, rinses, body soaps, hand soaps, and pumps that are assembled in containers containing content liquids such as cosmetic liquids and discharge the content liquids by pushing down the nozzle heads Is extended relatively laterally outward so that the discharged content liquid is directly discharged to a target location such as a palm.

  The general structure of the nozzle head of the pump described above (refer to FIG. 1 below) is a nozzle that extends laterally outward while slightly curving and descending on the side surface of the head body 2 whose upper surface is a push-up surface by hand. A cylinder 3 is provided, and a head neck cylinder 6 in which a nozzle passage 4 of the nozzle cylinder 3 is opened at an upper end portion of the head main body 2 is suspended.

  The nozzle head 1 is closely fitted to the upper end of a stem 8 having a ball valve 9, which is a part of the main part of the pump, with a head neck tube 6, and the nozzle head 1 is pushed down. Due to the downward displacement of the stem 8, the ball valve 9 is opened to suck up the content liquid, and the sucked up content liquid is discharged through the nozzle cylinder 3 to a target location.

  In addition, the combination of the guide cylinder 7 provided in the nozzle head 1 and the support cylinder 10 provided on the main portion side of the pump stably stabilizes the up-and-down displacement posture of the nozzle head 1 without tilting to the illusion. It is for holding.

  As a means for ensuring quality assurance as a product of a container with a pump in which this nozzle head is assembled, a conventional technique disclosed in Patent Document 1, that is, a stopper that exhibits a virgin function by making it impossible to push down the nozzle head, is used as a guide cylinder. There is known a technique in which a lower end edge of the support member is brought into contact with and attached to a support cylinder.

  This prior art disables the nozzle head from being lowered by the stopper, prevents unauthorized operation, and demonstrates a high virgin function.In use, the stopper is partially broken and removed, and the nozzle head is pushed down in this state. The liquid is discharged.

Japanese Utility Model Publication No. 06-081653

  The above-mentioned conventional technology certainly exhibits a high virgin function, but if you reattach the stopper that has been partially broken and removed, it may be difficult to see the reattachment at first glance. There is a demand for a container of this type that is unsatisfactory and that discharges the content liquid even once, so that it can be easily identified and that it exhibits a higher virgin function.

  Therefore, the present invention was created to satisfy the above-mentioned demands in the prior art, and it is a technical problem to provide a virgin function to the nozzle port, so that the liquid in the container has never been discharged. It is an object of the present invention to make it possible to easily identify whether the liquid has already been discharged.

Among the means for solving the above technical problems, the main configuration of the present invention is as follows.
The nozzle head is provided with a nozzle cylinder extending laterally outward on the side of the head main body with the upper surface as a push-down surface by hand,
Assembling unused identifiers in the vicinity of the nozzle opening, which is at least the tip opening, in the nozzle cylinder,
The unused identification body is inserted into the nozzle cylinder without interfering with the discharge of the content liquid, so that it cannot be pulled out, and the identification section that covers and closes the nozzle opening is mounted. Comprising a connecting piece that can be easily connected to the shredder
The head body, that it Kumitsui covering the like covering the extending direction of the nozzle tube, providing a cover stopper for disabling the descending displacement of the head main body,
The identification unit is configured with a palate piece that covers and closes the nozzle port from outside without being assembled and fixed to the nozzle port, and a knob piece that is connected to the palate piece via a flexure part,
It is in.

  Since the identification unit covers and closes the nozzle port from the outside, it is impossible to discharge the content liquid unless the identification unit is removed from the nozzle port. It breaks and is separated from the mounting part and removed from the nozzle opening.

Since the identification part only covers and closes the nozzle opening from the outside, it is difficult to assemble the nozzle opening when the connecting piece is broken, so the connecting piece is broken once and separated from the mounting part. It is almost impossible to re-attach the identified part to the nozzle port. Therefore, the container can be used or not used simply by checking the presence or absence of the identification part or touching the identification part and confirming the state of attachment to the nozzle port. Can be easily and accurately identified. That is, since the palate piece is not assembled and fixed to the nozzle opening, it is almost impossible to reattach the identification part separated from the mounting part by breaking the connecting piece to the nozzle opening as it is. By picking and pulling the knob with a fingertip, it becomes easy to apply a strong external force to the identification part, which makes it easy to break the connecting piece, and the knob piece is integrated with the palate piece. As a result, the identification unit can be easily recognized in appearance, and thus the identification determination by the identification unit can be performed naturally.

Unless the cover stopper is removed from the head body, the downward displacement of the nozzle head is disabled and unauthorized use of the liquid content is disabled.Therefore, the unused identification action by the unused identifier and the unauthorized use prevention action by the cover stopper A high virgin function can be obtained.

Another configuration of the present invention is to cover the assembly of the cover stopper to the head main body including the identification portion of the unused identifier mounted on the nozzle cylinder in addition to the main configuration described above. is there.

When the cover stopper is attached to the head main body, including the identification part of the unused identification object mounted on the nozzle cylinder, the identification part of the unused identification object located at the tip of the nozzle cylinder is Since the cover stopper covers and protects, it is possible to prevent the occurrence of inconvenience that the identification unit comes into contact with other articles and unintentionally separates during handling.

In addition to the main configuration described above, another configuration of the present invention covers the assembly of the cover stopper to the head main body except for the identification portion of the unused identification body mounted on the nozzle cylinder, The opening portion opened to the cover stopper so as to face the mouth is sized so that the identification portion cannot pass through.

If the cover stopper is attached to the head body except for the identification part, and the opening part of the cover stopper is sized so that it cannot pass through the identification part, it is identified as unused. Since the part is conspicuously positioned, it is easy to recognize the unused state.To switch to the used state, in addition to the method of removing the cover stopper after separating the identification part, the operation of removing the cover stopper It is possible to carry out by a method of performing separation.

  In addition to the main configuration described above, another configuration of the present invention includes a main body piece that is inserted and assembled into the nozzle cylinder from the nozzle port, and a protruding end provided on the main body piece. A support piece that keeps the main body piece in a fixed position by making it non-rotatable contact with the inner peripheral surface of the nozzle cylinder, and a mechanism that is provided at the insertion end of the main body piece and that engages with the nozzle passage opening edge in the head body It consists of a stop piece.

  In the case where the mounting portion is composed of a main body piece, a support piece, and a locking piece, the mounting portion is engaged with the insertion end of the main body piece, that is, the base end opposite to the distal end where the identification portion is connected via the connection piece. Since the stop piece is provided, the mounting portion cannot be extracted to the nozzle cylinder inner shell nozzle port side. For this reason, the identification portion cannot be detached from the nozzle port unless the connecting piece is broken. In addition, since the support piece keeps the posture of the body piece inserted in the nozzle cylinder 3 constant and prevents the occurrence of unnecessary displacement such as rotational displacement, the mounting portion for the content liquid passing through the nozzle cylinder Can be made constant, and the occurrence of unauthorized breakage of the connecting piece due to unnecessary displacement can be prevented.

  In addition to the configuration of the mounting portion described above, another configuration of the present invention is configured such that the support piece is configured in the shape of an elongated corrugated plate.

  In the case where the support piece is formed in the shape of an elongated corrugated plate, the support piece imparts an appropriate flow resistance to the content liquid passing through the nozzle passage.

  Another configuration of the present invention is such that, in addition to the configuration of the mounting portion described above, the support piece is configured in a plate shape in which a part of the main body piece is widened.

  In the case where the support piece is configured as a plate piece in which a part of the main body piece is widened, the main body piece and the support piece are allowed to function as a “rectifying plate” for the content liquid passing through the nozzle passage. Can do.

  In addition to the configuration of the mounting portion described above, another configuration of the present invention makes the locking piece non-displaceable by contacting the main body piece portion in the vicinity of the locking piece in a non-rotatable manner with the inner peripheral surface of the nozzle cylinder. It is configured by projecting a regulating piece to be held.

  In the case where the restricting piece protrudes from the main body piece portion in the vicinity of the engaging piece, it is possible to stably ensure that the engaging piece is attached to the nozzle passage opening edge in the head main body.

Since the present invention has the above-described configuration, the following effects can be obtained.
Since the identification unit covers and closes the nozzle port from the outside, it is impossible to discharge the content liquid unless the identification unit is removed from the nozzle port. It breaks and is separated from the mounting part and removed from the nozzle opening.

The identification part is difficult to be assembled to the nozzle opening when the connecting piece is broken, and therefore it is almost impossible to reattach the identification part once separated from the mounting part by breaking the connecting piece. Therefore, the use or non-use of the container can be easily and accurately identified simply by confirming the presence / absence of the identification part or the mounting state of the nozzle port. In other words, since the identification part is not the one in which the palate piece is assembled and fixed to the nozzle opening, it is almost impossible to reattach the identification part separated from the mounting part by breaking the connecting piece as it is to the nozzle opening. In addition, the connecting piece can be easily broken, and the identification judgment by the identification unit can be performed naturally, which makes the identification unit easier to handle and unused by the identification unit. Can be easily identified.

Unless the cover stopper is removed from the head body, the downward displacement of the nozzle head is disabled and unauthorized use of the liquid content is disabled.Therefore, the unused identification action by the unused identifier and the unauthorized use prevention action by the cover stopper A high virgin function can be obtained.

If the cover stopper is attached to the head body, including the identification part of the unused identification body attached to the nozzle cylinder, the identification part will come into contact with other articles during handling and will be unintentionally separated. Therefore, it is possible to prevent the occurrence of inconveniences, and thus safe handling can be obtained.

If the cover stopper is attached to the head body except for the identification part, and the opening part of the cover stopper is sized so that it cannot pass through the identification part, it is identified as unused. Since the part is conspicuously located, it becomes easy to recognize the unused state, and it is easy to identify, and the separation of the identification part can be achieved by removing the cover stopper, so that it can be used. Switching is easy.

  If the mounting part is composed of a main body piece, a support piece, and a locking piece, the identification part cannot be detached from the nozzle port without breaking the connecting piece. The action of the nozzle cylinder with respect to the content liquid can be conveniently set because the effect of the mounting part on the content liquid passing through the nozzle cylinder can be made constant. This makes it possible to prevent unnecessary breakage of the connecting piece and to obtain safe handling.

  In the case where the support piece is configured in the shape of an elongated corrugated plate, the support piece gives an appropriate flow resistance to the content liquid passing through the nozzle passage, and thereby the discharge state of the content liquid is desired. It becomes easy to assume.

  In the case where the support piece is configured as a plate piece in which a part of the main body piece is widened, the main body piece and the support piece are allowed to function as a “rectifying plate” for the content liquid passing through the nozzle passage. Therefore, the discharge state of the content liquid can be made safe and preferable.

  In the case where the restricting piece protrudes from the main body piece portion in the vicinity of the engaging piece, it is possible to stably secure the engaging piece of the engaging piece with respect to the nozzle passage opening edge in the head body. A reliable and stable discriminating action by the unused discriminator can be obtained.

Embodiments of the present invention will be described below with reference to FIGS.
A nozzle head 1 (see FIG. 1) according to the present invention is composed of a head body 2, an unused discriminator 12, and a cover stopper 25. A nozzle cylinder 3 extending in a laterally outward direction while being curved downward is integrally provided, and a head neck cylinder 6 having a nozzle passage 4 of the nozzle cylinder 3 opened at the upper end portion is suspended from the head body 2. Yes.

  The nozzle head 1 is a part of the main part of the pump, and is fitted to the upper end portion of the stem 8 with the ball valve 9 in a tightly and immovably fitted manner with the head neck tube 6. Due to the downward displacement of the stem 8 accompanying the depression, the ball valve 9 is opened to suck up the content liquid, and the sucked up content liquid is discharged through the nozzle cylinder 3 to a target location.

  The stem 8 having a cylindrical shape forms a stepped portion for setting a limit position with a fitting assembly on the outer peripheral surface of the upper end portion that is tightly inserted into the head neck tube 6, and is inclined and contracted downward on the inner peripheral surface of the upper end portion. A ball seat 9 is assembled by surrounding a diameter inner flange piece and a ball valve 9 is assembled, and a plurality of vertical stripes are provided on the inner circumferential surface on the upper side of the inner collar piece forming the valve seat surface. Thus, a passage that is not closed by the ball valve 9 is secured, and a projecting piece that prevents the ball valve 9 from coming out of the stem 8 is formed at the upper end of each vertical strip.

  The combination of the guide cylinder 7 suspended from the head body 2 in a form surrounding the nozzle neck cylinder 6 and the support cylinder 10 erected from the assembly cylinder 11 on the main portion side of the pump is vertically By fitting in a slidable manner in the direction, the up-and-down displacement posture of the nozzle head 1 can be stably held without being inclined to the illusion.

  The combination of the guide cylinder 7 and the support cylinder 10 may be provided with a detent function portion using a key structure, but this may be provided as necessary.

  1 to 7, a mounting portion 20 that is inserted and assembled in the nozzle cylinder 3 without impeding the discharge of the content liquid, and an identification portion 13 that covers and closes the nozzle port 5 from the outside, A configuration is shown in which a first configuration example of an unused identification body 12 configured from a connecting piece 19 that easily couples the identification portion 13 to the mounting portion 20 is shown.

  In the first configuration example of the unused identifier 12, the identification unit 13 includes a palate piece 14 that covers and covers the nozzle port 5 from the outside without being assembled and fixed to the nozzle port 5. The pawl piece 14 (see FIG. 6) is configured with a gripping piece 17 that is continuously provided via a flexible portion 18 that is easily bent and is easy to pick with a fingertip. And the rear surface of the flange piece 15 is formed with an insertion piece 16 that protrudes with an outer diameter sufficiently smaller than the opening diameter of the nozzle port 5 and provides a connection portion with the connection piece 19. It is impossible to assemble the identification unit 13 alone into the nozzle port 5.

  In addition, a plurality of lateral protrusions for preventing slipping are provided on the surface of a plate-like tab piece 17 that is provided in a hanging manner on the palate piece 14 via a lateral groove-like bending portion 18. By picking the knob 17 with the fingertip and pulling it slightly upward in the extending direction of the nozzle cylinder 3, the connecting piece 19 can be broken to achieve the removal of the identification portion 13 from the nozzle port 5. it can.

  The mounting portion 20 is provided with an elongated corrugated plate-like support piece 22 integrally formed on an elongated plate-like main body piece 21 over substantially the entire length of the main body piece 21, and is locked to a base end that is an insertion end of the main body piece 21. The support piece 22 is configured such that the edge of each wave head is brought into non-rotatable contact with the inner peripheral surface of the nozzle cylinder 3, that is, the passage surface of the nozzle passage 4, in the support piece 22. The assembly posture of the main body piece 21 in the cylinder 3 is fixed and fixed, and the locking piece 23 is locked to the opening edge of the nozzle passage 4 in the head main body 2, so that the nozzle opening 5 of the mounting portion 20 is fixed. As is apparent from the overall perspective view of the unused identifier 12 shown in FIG. 5, the elastic deformation is used so that insertion from the nozzle port 5 side is possible. It is composed of a pair of projecting pieces inclined in an arrow shape.

  A pair of restricting pieces 24 are attached to the main body piece 21 in the vicinity of the locking piece 23 so that the projecting ends thereof are brought into non-rotatable contact with the inner peripheral surface of the nozzle cylinder 3. By the contact with the inner peripheral surface of the cylinder 3, the locking that prevents the locking piece 23 from coming out of the opening edge of the nozzle passage 4 is secured.

  The cover stopper 25 (see FIG. 1) that covers and assembles the nozzle head 1 in a cover shape from the extending direction side of the nozzle cylinder 3 has a cylindrical shape with the entire rear open, A hook cylinder piece 26 having a hook-like protruding portion covering the entire head main body 2 including the nozzle cylinder 3 is provided, and the lower half portion is positioned on the upper surface of the assembled cylinder 11 on the pump main body side, and the support cylinder 10. And an inner flange-like stopper piece 29 that abuts against the lower end of the guide cylinder 7 of the head body 2 is provided in the lateral direction on the inner surface of the assembled cylinder piece 28. The stopper piece 29 prevents the cover stopper 25 from being assembled to the nozzle head 1 unless the cover stopper 25 is slid from the extending direction side of the nozzle cylinder 3.

  In the case of the first embodiment of the cover stopper 25 shown in FIG. 1, the cover stopper 25 covers the entire nozzle head 1 including the identification portion 13 of the unused identification body 12 (see FIG. 2). In addition to preventing the head body 2 from being lowered and displaced, the identification unit 13 is protected, and the safety of the identification unit 13 is sufficiently enhanced.

  In the first embodiment of the cover stopper 25, the removal operation of the cover stopper 25 and the separation operation of the identification unit 13 in the unused identification body 12 are performed completely separately.

  In the case of the second embodiment of the cover stopper 25 shown in FIG. 3, the opening 27 formed at the tip of the flange piece 26 of the cover stopper 25 is formed in a size that prevents the identification portion 13 from passing through. The cover stopper 25 covers the nozzle head 1 except for the identification portion 13 of the unused identification body 12, so that the identification portion 13 is exposed to the most prominent tip portion of the rod piece 26. (See FIG. 4), its presence is emphasized, which makes it very easy to identify used and unused.

  In the second embodiment of the cover stopper 25, when the cover stopper 25 is removed after the identification portion 13 is separated, it is more reliable to check the unused state of the container with the pump. When the separation of the identification unit 13 is achieved together with the removal of 25, switching to the use state is simplified.

  In the case of discharging the content liquid, in the case of the first embodiment, after the cover stopper 25 is removed, the knob 17 is pulled to separate and remove the identification portion 13 to open the nozzle port 5 ( In this state, the mounting portion 20 of the unused identification body 12 remains attached in this state, but the remaining mounting portion 20 is connected to the nozzle passage 4. Appropriate discharge flow resistance is given to the content liquid discharged through the nozzle, so that the discharge operation of the content liquid is made safe, and an appropriate adhesion force to the content liquid remaining in the nozzle cylinder 3 is given. This prevents the residual liquid in the nozzle cylinder 3 from dripping unnecessarily from the nozzle opening 5 and becoming dirty.

  When discharging the content liquid, in the case of the second embodiment, the cover stopper 25 is removed after the identification portion 13 is separated and the nozzle port 5 is opened, or together with the removal of the cover stopper 25. The identification unit 13 is separated, thereby enabling the operation of pushing down the nozzle head 1 to discharge the content liquid. However, the mounting unit 20 remaining in the nozzle cylinder 3 performs the same operation as in the first embodiment. Demonstrate.

  FIG. 8 shows a second configuration example of the unused discriminator 12, and the second configuration example of the unused discriminator 12 includes the bending portion 18 of the discriminating portion 13 and the elongated plate piece in a wave shape. The support piece 22 of the mounting portion 20 is constituted by a short corrugated piece positioned in the vicinity of the nozzle port 5, and the support piece 22 is shortened compared to the first configuration example. Since the discharge flow resistance with respect to the content liquid becomes small, it is preferable to apply to the content liquid having a relatively high viscosity.

  FIG. 9 shows a third configuration example of the unused identification body 12, and the third configuration example of the unused identification body 12 includes the support piece 22 of the mounting portion 20 in the vicinity of the nozzle opening 5. The support piece 22 is fixed by, for example, fitting the side edge to the inner peripheral surface of the nozzle cylinder 3 to rectify the content liquid. The liquid is discharged in a state to prevent the occurrence of defective scattering of the discharged liquid.

  In addition, although the 1st-3rd example was shown as a structural example of the unused identification body 12, the structure of the unused identification body 12 is not limited to this, For example, the identification part in each illustrated structural example 13 and the mounting part 20 may be rearranged.

  As described above, the nozzle head of the pump according to the present invention discriminates the use or non-use of the pump-equipped container based on the presence or absence of the identification unit that is sufficiently conspicuous by directly closing the nozzle opening. As a simple means to enhance the virgin function of a container with a pump, a wide range of usage can be expected.
