Description

The present invention relates to a discharge pump and a pump container that discharges the contents contained in the container body using a pump mechanism.

Recently, disinfection of hands has become necessary as a measure to prevent infection or the spread of infection. For example, disinfectants such as rubbing alcohol are placed at the entrances of various facilities, such as offices, stores, hospitals, and public facilities, to encourage visitors to disinfect their hands. The disinfectant is stored in a pump container equipped with a discharge pump, such as that disclosed in Patent Document 1. The discharge pump has a nozzle head with a nozzle from which the contents are discharged, and a pump mechanism, and is configured so that a simple operation such as pressing down on the nozzle head with the palm of the hand activates the pump mechanism, sucking up the contents stored in the container body and discharging a predetermined amount of disinfectant from the nozzle.

In addition, these facilities are required to regularly disinfect and sterilize doorknobs, handrails, and other areas that are touched by hands. Furthermore, restaurants and other establishments are required to disinfect and sterilize tables and other surfaces. In such cases, for example, hand wrap containers are used, which allow paper towels, etc. to be easily soaked in disinfectant dispensed from the container, and spray containers are used to directly spray disinfectant onto disinfected areas, etc.

JP 2019-81592 A

As such, at present, it is necessary to prepare multiple disinfectants contained in containers of different shapes depending on the application. For this reason, it would be preferable to have a single container that can be used for these various applications. However, the amount of disinfectant required for disinfecting hands and the direction in which the disinfectant is discharged are different from the amount of disinfectant required for disinfecting tables and the like. Therefore, it would be preferable to be able to easily switch to a method of use that suits the application, such as being able to discharge an appropriate amount of disinfectant for various applications in a direction that suits the application.

The objective of the present invention is to provide a discharge pump and pump container that can discharge an appropriate amount of contents in a variety of ways depending on the application and that is easy to operate.

In order to solve the above problem, a discharge pump according to the present invention includes an attachment part that is attached to a mouth part of a container body that contains contents, a press-down head that is provided on the attachment part so as to be pressable along an axial direction of the mouth part, a pump mechanism that discharges the contents inside the container body in response to a press-down operation of the press-down head, a discharge port part having a discharge port for discharging the contents discharged by the pump mechanism , a holding part that holds the discharge port part on the press-down head so as to be displaced between a first orientation in which the discharge port faces the same axial direction as the mouth part and a second orientation in which the discharge port faces a direction intersecting the axial direction, and a regulating part that is provided on the holding part and displaced in response to the displacement of the discharge port part, wherein the press-down head is movable downward in both the first orientation and the second orientation, and the contents discharged from the discharge port are discharged to the outside by the downward movement of the press-down head, and the regulating part regulates the range in which the press-down head can be pressed along the axial direction to different amounts in the first orientation and the second orientation .

The discharge pump according to the present invention is preferably configured to have an opening that is arranged coaxially with the discharge port, and an opening frame that is arranged at a predetermined distance from the discharge port, the opening frame being held in the holding portion so as to be displaceable in the first orientation and the second orientation together with the discharge port, and the contents are discharged to the outside through the inside of the opening frame at each of the positions in the first orientation and the second orientation.

In the discharge pump according to the present invention, it is also preferable that the discharge port portion has a discharge tube having the discharge port and a rotating tube communicating with the discharge tube, and the pressing head is configured to have a rotating tube holding portion that rotatably holds the rotating tube, and a flow path portion that communicates with the pump mechanism and the rotating tube.

To solve the above problem, the discharge container according to the present invention is characterized by comprising the above discharge pump and the above container body.

The discharge pump according to the present invention includes a holding part that holds the discharge port part on the pressing head so that the discharge port can be displaced between a first direction in which the discharge port faces the same axial direction as the mouth part and a second direction in which the discharge port faces a direction intersecting the axial direction, and a restricting part that restricts the range in which the press head can be pressed along the axial direction to different amounts in the first direction and the second direction. Therefore, when the discharge port part is displaced so that the discharge port faces the first direction, the content liquid is discharged at a discharge amount corresponding to the first direction, and when the discharge port part is displaced so that the discharge port faces the second direction, the content liquid is discharged at a discharge amount corresponding to the second direction, which is different from the first direction. The direction and discharge amount of the discharge port can be easily switched by displacing the discharge port part with the holding part. From these points, according to the present invention, it is possible to provide a discharge pump and a pump container that can discharge an appropriate amount of contents in various ways according to the purpose and have good operability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a discharge pump and a pump container
Fig. 1 is a partial cross-sectional view of a discharge pump 100a according to the present embodiment. As shown in Fig. 1, the pump container 100 includes a container body 10 and a discharge pump 100a attached to a mouth portion 11 of the container body 10. In this embodiment, the description will be given on the assumption that the container body 10 contains a disinfectant such as disinfectant alcohol or a sodium hypochlorite aqueous solution for disinfection as the contents. However, in the present invention, the container body of the pump container can contain various liquids other than the disinfectant.

The discharge pump 100a includes an attachment part 20 that is attached to the mouth part 11 of the container body 10, a discharge port part 30 having a discharge port 31 for discharging the contents to the outside, a press-down head 40 that is provided on the attachment part 20 so as to be pressed down toward the container body 10 along the axial direction of the mouth part 11, a pump mechanism 50 that operates in response to the pressing operation of the press-down head 40, a discharge cover 60 having an opening frame 61, and a rotating holding part 70 (holding part) that rotatably holds the discharge port part 30 and the discharge cover 60 on the press-down head 40 so that the discharge port 31 and the opening frame 61 are displaced in a first direction (FIGS. 1, 3, 4) and a second direction (see FIG. 5). Here, in the first direction, the discharge port 31 faces in the same axial direction as the mouth part 11, and in the second direction, the discharge port 31 faces in a direction intersecting the mouth part 11 in the axial direction. In this embodiment, the direction intersecting the axial direction means a direction approximately perpendicular to the axial direction. In this embodiment, the pump container 100 is configured so that when the discharge port 31 and the opening frame 61 are positioned in a first orientation and a second orientation, the amount of contents that corresponds to each position is discharged from the discharge port 31.

The specific configuration of each part will be described below. In the following, "upper" and "lower" indicate relative positional relationships, and when the container body 10 is placed in the upright position shown in FIG. 1 and the discharge pump 100a is attached to the mouth portion 11 of the container body 10, the side on which the container body 10 is located will be referred to as "lower" and the side on which the push-down head 40 is located will be referred to as "upper". Furthermore, "axial direction" refers to the axial direction of the central axis O of the mouth portion 11 of the container body 10. Furthermore, the direction perpendicular to the central axis O is referred to as the radial direction, and the direction going around the central axis O is referred to as the circumferential direction.

As shown in FIG. 1, the container body 10 comprises a bottom 12, a body 13, a shoulder 14, and the mouth 11, which are integrally formed. In the illustrated example, the body 13 is gradually tapered in diameter from the bottom 12 toward the shoulder 14. The mouth 11 has a smaller diameter than the body 13, and the mouth 11 and the body 13 are connected by the shoulder 14. A male thread 11a is provided on the outer circumferential surface of the mouth 11.

The mounting portion 20 comprises a cap portion 21 that is detachably mounted on the mouth portion 11, and an outer cylinder 22 that covers the outside of the cap portion 21, which are arranged coaxially with the central axis O. The cap portion 21 has a female thread 21a on its inner peripheral surface, which threads into the male thread 11a provided on the mouth portion 11. The top wall surface of the cap portion 21 is annular, and its central portion forms an insertion hole 21b into which the stem 52 of the pump mechanism 50 and the like are inserted. The top wall surface of the cap portion 21 covers the upper opening edge of the mouth portion 11.

The outer cylinder 22 is generally cylindrical in shape and comprises, from bottom to top in the axial direction, a lower outer cylinder 22a, a connecting portion 22b, and an upper outer cylinder 22c. The lower outer cylinder 22a covers the outside of the outer peripheral surface of the cap portion 21. The connecting portion 22b connects the lower outer cylinder 22a and the upper outer cylinder 22c. The cap portion 21 is connected to the inside of the connecting portion 22b. The upper end of the upper outer cylinder 22c is positioned above the top wall surface of the cap portion 21. The pressing head 40 is inserted into the upper outer cylinder 22c so as to be movable up and down along the axial direction.

The discharge port section 30 is configured as a spray nozzle that sprays the liquid in a mist form from the discharge port 31. In this embodiment, the discharge port section 30 includes a discharge tube 32 having the discharge port 31, a rotating tube 33 that communicates with the discharge tube 32, and a sliding shaft section 35 that is connected to the rotating tube 33 via a partition wall 34.

As shown in Figs. 1 and 2(b), the central axis of the discharge tube 32 and the central axis of the rotating tube 33 are approximately perpendicular to each other. The lower end of the discharge tube 32 is connected to the rotating tube 33, and the discharge tube 32 and the rotating tube 33 form an approximately L-shaped flow path as shown by arrows e and f in Fig. 2(b). The downstream end of the rotating tube 33 has an expanded diameter, and the upper flow path section (flow path shown by arrow d (Fig. 2(b))) of the flow path section 45 (Fig. 1) described later is inserted inside. The rotating tube 33 and the sliding shaft section 35 are arranged coaxially in the radial direction of the mouth section 11. Therefore, the rotating tube 33, the sliding shaft section 35, and the discharge tube 32 have an appearance similar to a T-shaped pipe.

The rotating cylinder 33 is arranged in the pressing head 40 so that it can rotate around the central axis of the rotating cylinder 33 as the rotation axis. When the discharge cylinder 32 is arranged so that the direction of the discharge port 31 is in the first direction, if the discharge cylinder 32 is tilted, the rotating cylinder 33 rotates in the pressing head 40, and the direction of the discharge port 31 is displaced to the second direction. The reverse is also true; when the discharge cylinder 32 is arranged so that the direction of the discharge port 31 is in the second direction, if the discharge cylinder 32 is pushed up around its lower end as the center of rotation, the rotating cylinder 33 rotates, and the direction of the discharge port 31 is displaced to the first direction. In this way, the rotating cylinder 33 is supported from below by the rotating cylinder support part 44 provided in the pressing head 40 so that it can rotate. As shown in Figures 4 and 5, the sliding shaft 35 is sandwiched between the sliding shaft holder 47 that is suspended from the top wall 43b of the pressing head 40, and is rotatably held within the sliding shaft holder 47. In other words, the rotating cylinder support 44 and the sliding shaft holder 47 constitute the rotating cylinder holder of the present invention.

As shown in FIG. 1, the pressing head 40 includes, in order from the bottom to the top in the axial direction, a holding base portion 41, a lower head portion 42, an upper head portion 43, the rotating cylinder support portion 44, a flow path portion 45, an insert cylinder 46, and the sliding shaft holding portion 47.

The holding base 41 is housed and held inside the lower head 42, and holds the stem 52 of the pump mechanism 50, etc. A fitting tube 46 is inserted into the top wall surface of the holding base 41 so as to penetrate in the thickness direction. The lower end side of the fitting tube 46 is fitted into the inside of the stem 52 and communicates with the flow path inside the stem 52. The upper end side of the fitting tube 46 communicates with the flow path section 45.

The lower head portion 42 is formed in a short cylindrical shape. The lower head portion 42 is configured to be movable up and down in the axial direction within the outer tube 22 of the mounting portion 20 while the holding base portion 41 is housed and held inside.

The upper head portion 43 has a rectangular cylindrical peripheral wall portion 43a and a top wall portion 43b that covers the upper portion of the peripheral wall portion 43a. As shown in Figures 4 and 5, a guide groove hole 43c is formed in the top wall portion 43b from a position intersecting the central axis O toward the peripheral wall portion 43a. The discharge tube 32 of the discharge port portion 30 is inserted into this guide groove hole 43c. In addition, the top wall portion 43b is provided with a standing wall 43d that stands upward from the groove end portion of the guide groove hole 43c. When the discharge port portion 30 is arranged so that the discharge port 31 faces the first direction, the discharge tube 32 of the discharge port portion 30 and the standing wall 43d abut against each other, and the upper end of the standing wall 43d abuts against the lower surface of the top wall surface 71 of the rotation holding portion 70 (see Figure 4). In addition, the peripheral wall portion 43a is provided with a pair of pivot shafts 43e that protrude radially outward on both sides of the peripheral wall portion 43a when viewed from the front as shown in FIG. 1. The pivot shafts 43e are inserted into bearing holes 72a formed in the side surface portion 72 of the pivot holder 70.

The rotating cylinder support part 44 is connected to the holding base part 41. The rotating cylinder support part 44 supports the rotating cylinder 33 and the sliding shaft part 35 so that they can rotate around the central axis of the rotating cylinder 33 as the rotation axis. By being supported by the rotating cylinder support part 44, the discharge port part 30 moves in the axial direction in conjunction with the axial movement of the pressing head 40.

The flow path section 45 has a lower flow path section (a part constituting the flow path represented by the arrow b in FIG. 2B) that communicates with the upper end of the insertion tube 46, an upper flow path section (a part constituting the flow path represented by the arrow d in FIG. 2B) that communicates with the rotating tube 33, and a middle flow path section (a part constituting the flow path represented by the arrow c in FIG. 2B) that connects the lower flow path section (arrow b) and the upper flow path section (arrow d). The lower flow path section (arrow b) and the upper flow path section (arrow d) form a flow path in a direction approximately perpendicular to the axial direction, and the middle flow path section (arrow c) forms a flow path in the same direction as the axial direction. In other words, the flow path section 45 forms an approximately U-shaped flow path with these. As described above, the upper flow path section (arrow d) is inserted into the rotating tube 33, and the flow paths between the upper flow path section and the rotating tube 33 are connected. In other words, the downstream end of the discharge port 30 (the downstream end of the rotating cylinder 33) that has an L-shaped flow path is connected to the upstream end of the U-shaped flow path 45. By adopting this configuration, the discharge port 30 is connected to the flow path 45 in a rotatable manner.

A pair of sliding shaft holders 47 are vertically attached from the underside of the top wall 43b of the upper head 43, and hold the sliding shaft 35 rotatably by sandwiching the outer circumferential surface of the sliding shaft holder 47.

Next, the pump mechanism 50 will be described. As shown in FIG. 1, the pump mechanism 50 includes a cylinder 51, a stem 52, a coil spring 53, etc., and a piston (not shown) is disposed within the cylinder 51. However, the configuration of the pump mechanism 50 is not particularly limited, and any configuration, including conventionally known ones, may be used as long as it is capable of delivering the contents within the container body 10 to the discharge port portion 30 side in response to the pressing action of the pressing head 40.

The pump mechanism 50 shown in the figure is roughly configured as follows. The cylinder 51 hangs down from the mouth 11 to the inside of the container body 10. A mounting tube 51a extending downward is disposed at the lower end opening of the cylinder 51. A suction tube 51b for sucking up the contents contained in the container body 10 is inserted into the mounting tube 51a. The stem 52 is disposed so as to be movable up and down in the axial direction while being biased upward by a coil spring 53. The stem 52 is inserted inside the coil spring 53. The coil spring 53 supports the stem 52 while being biased upward so as to be movable downward. The lower end of the coil spring 53 is inserted into the upper end of the cylinder 51. The upper end of the coil spring 53 is clamped by a clamping portion 54 disposed at the top of the stem 52.

The discharge cover 60 includes the opening frame 61 and a support portion 62 that supports the opening frame 61 at a predetermined distance from the pivot holder 70. When the discharge port portion 30 is arranged so that the discharge port 31 faces in a first direction (FIG. 1), the press head 40 can be pressed axially downward by, for example, placing a hand on the discharge cover 60 and pressing the discharge cover 60 axially downward.

As shown in FIG. 2(a), the opening frame 61 has a ring shape when viewed from above. The opening frame 61 has an opening 61a at the center thereof that is concentric with the discharge port 31. In addition, when viewed from the front (FIG. 1, etc.) and from the side (FIGS. 4 and 5), the opening frame 61 has multiple protrusions 61b that protrude upward in a wavy shape rather than a flat plate shape.

The opening frame 61 can be preferably made of polypropylene resin (PP), ABS resin, polyacetal resin (POM (polyoxymethylene resin)), polyethylene terephthalate resin (PET), high density polyethylene resin (HDPE), etc. Since each of these resins has high strength, forming the opening frame 61 (and the entire discharge cover 60) from these resins can give the opening frame 61 durability that can withstand repeated pressing operations during use.

As shown in FIG. 2(a), the support portion 62 is composed of four plate-like members 62a in this embodiment. The lower end of each plate-like member 62a is attached to the side portion 72 of the rotating holder 70, and the upper end is attached to the opening frame 61. As shown in FIG. 1 and FIG. 2(a), two of each plate-like member 62a are attached to the side portion 72, and the adjacent plate-like members 62a are opened widely on the front side and the back side 73 side of the rotating holder 70. When the discharge port 31 and the opening frame 61 are oriented in the second direction, the opening between the plate-like members 62a is located above and below in the axial direction. In the second direction, the contents discharged from the discharge port 31 may be discharged from the opening between the plate-like members 62a to the outside of the discharge cover 60 (see FIG. 5).

As shown in Figures 1 and 2(a), the pivot holder 70 has a top wall surface 71 having an insertion hole 71a into which the discharge port 30 is inserted, a side surface portion 72 suspended from the top wall surface 71, and a back surface portion 73 provided between the side surface portions 72, and the front surface is open.

1, the side portion 72 is provided with the bearing hole 72a. As described above, the pivot shaft portion 43e is inserted into the bearing hole 72a. The pivot holder 70 is attached to the upper head portion 43 so as to be pivotable about 90 degrees from the orientation corresponding to the first orientation shown in FIG. 1 to the second orientation shown in FIG. 5, with the pivot shaft portion 43e as the pivot center. Also, as shown in FIG. 5, when the pivot holder 70 is pivoted to the orientation corresponding to the second orientation, the end of the top wall surface 71 abuts against the top wall surface of the lower head portion 42, and further pivoting is restricted. Also, in the second orientation, the back portion 73 is disposed axially above the mouth portion 11. Also, in the second orientation, the back portion 73 has an area sufficient to cover the entire surface of the top wall portion 43b of the upper head portion 43. Furthermore, in the second orientation, the upper end of the erected wall 43d and the top wall surface 71 are spaced apart.

The rotating holder 70 is further provided with a restricting portion 74 that restricts the range in which the pressing head 40 can be pressed to different amounts in the first and second directions. As shown in Figs. 1 and 2(a), the restricting portion 74 is formed as an abutment piece that protrudes radially from the lower end of the side portion 72. In this embodiment, the pressing head 40 is provided so as to be movable in the axial direction within the upper outer tube 22c of the mounting portion 20. When the discharge port 31 and the opening frame 61 are in the first direction, the restricting portion 74 abuts against the upper end of the upper outer tube 22c of the mounting portion 20 when the rotating holder 70 moves axially downward, restricting further axial downward movement of the pressing head 40 (see Figs. 3 and 4).

On the other hand, since the restricting portion 74 is provided on the side portion 72, when the rotating holder 70 rotates from the orientation corresponding to the first orientation to the orientation corresponding to the second orientation, the position of the restricting portion 74 also rotates approximately 90°. Therefore, in the second orientation, the position of the restricting portion 74 moves upward from the first orientation. Also, at that time, the restricting portion 74 is located inside the upper outer tube 22c, and is in a position that does not interfere with the upper outer tube 22c (see FIG. 5). The amount by which the pressing head 40 can be pressed down in the second orientation (maximum stroke amount S1) is represented by the distance that the pressing head 40 moves in the axial direction from a state in which no axial downward force is applied to the pressing head 40 until the lower end of the lower head portion 42 abuts against the top surface of the cap portion 21.

In contrast, by providing the regulating portion 74 at the lower end of the side portion 72 of the rotating holding portion 70, in the first orientation, as shown in Figures 3 and 4, the regulating portion 74 abuts against the upper end of the upper outer tube 22c before the push-down head 40 reaches the maximum stroke amount S1 in the second orientation. Therefore, the maximum stroke amount S2 of the push-down head 40 in the first orientation is shorter than that in the second orientation. The amount of contents delivered by the pump mechanism 50 varies depending on the amount of depression of the push-down head 40. By providing the regulating portion 74 on the rotating holding portion 70 and moving the position of the regulating portion 74 upward and/or to a position that does not interfere with the upper outer tube 22c in the second orientation, the maximum stroke amount of the push-down head 40 can be changed, and different amounts of contents can be discharged in the first orientation and the second orientation.

Next, the operation of the discharge pump 100a will be described with reference to Figures 1 to 5. Note that the display of the container body 10 and some of the reference numerals are omitted in Figures 4 and 5.

(First Orientation)
With reference to FIG. 4, a description will be given of the discharge operation by the discharge pump 100a when the discharge port portion 30 and the discharge cover 60 are arranged so that the discharge port 31 and the opening frame 61 are oriented in a first direction.

In the first orientation, the opening frame 61 (discharge cover 60) functions as the first pressing operation part. When the opening frame 61 is pressed in the axial direction by placing the palm of the hand or the like against it, as shown in FIG. 4(a), the force applied to the rotating holding part 70 via the support part 62 is transmitted to the pressing head 40 via the upper end of the erected wall 43d that abuts against the top wall surface 71. As a result, the pressing head 40 moves axially downward. This state is shown in FIG. 3 and FIG. 4(b).

When the push-down head 40 moves, the stem 52 moves axially downward, and the pump mechanism 50 is activated. The contents sucked up by the pump mechanism 50 are sent axially upward by the stem 52 and the fitting tube 46 (arrow a) (see FIG. 2(b)). The contents then flow from the upper end of the fitting tube 46 into the lower flow path section (arrow b) that intersects with the axial direction, and pass through the middle flow path section (arrow c) and the upper flow path section (arrow d) in that order, passing through the U-shaped flow path in the flow path section 45, and flowing into the rotating tube 33 (arrow e). The contents that flow into the rotating tube 33 are sent axially upward through the discharge tube 32 (arrow f) toward the discharge port 31.

The discharge port 31 and the opening frame 61 are arranged coaxially. The contents are discharged from the discharge port 31 with a predetermined force imparted by the pump mechanism 50. Therefore, the contents are sprayed upward while expanding in diameter compared to when they were discharged from the discharge port 31. The sprayed contents are then discharged above (outside) the opening frame 61 while passing through the inside of the opening 61a of the opening frame 61, and the contents adhere to the palm or the like that presses down on the opening frame 61. At this time, the maximum stroke amount of the pressing head 40 is set to S2 by the regulating part 74 as described above. Therefore, the amount of contents that adhere to the palm or the like corresponds to the maximum stroke amount S2 in the first direction.

(Second Orientation)
Next, with reference to FIG. 5, a description will be given of the discharge operation by the discharge pump 100a when the discharge port portion 30 and the discharge cover 60 are arranged so that the discharge port 31 and the opening frame 61 are oriented in a second direction.

In the second orientation, the back portion 73 functions as a second pressing operation portion. For example, when the back portion 73 is pressed in the axial direction with a finger or the like, the end of the top wall surface 71 abuts against the top wall surface of the lower head portion 42, so the force applied to the rotating holding portion 70 is transmitted to the pressing head 40 via the lower head portion 42. As a result, the pressing head 40 is pressed down. When the pressing head 40 is pressed down, the contents are sent from inside the container body 10 to the discharge port portion 30 side by the pump mechanism 50, as in the first orientation, and are discharged from the discharge port 31. Since the discharge port 31 faces in a direction intersecting the axial direction, the contents are also discharged in that direction.

In the second orientation, by adjusting the distance between the discharge port 31 and the opening frame 61 and the force of the contents being discharged, the contents discharged from the discharge port 31 can be made to pass through the inside of the opening frame 61 and be discharged to the outside of the discharge cover 60, or a part or all of the discharged contents can be made to be discharged to the outside of the discharge cover 60 through the opening between the plate-shaped members 62a. Also, as described above, in the second orientation, the regulating portion 74 is moved to a position where it does not interfere with the upper outer tube 22c. Therefore, the maximum stroke amount of the pressing head 40 is set to S1 as described above. Therefore, in the second orientation, more contents can be discharged than in the first orientation.

(Switching operation)
Next, the switching operation of the orientation of the discharge port 31 and the opening frame 61 and the discharge amount of the contents will be described. In the pump container 100 of this embodiment, the rotating holder 70 is held rotatably with the rotating shaft 43e as the center of rotation with respect to the pressing head 40. Therefore, when the discharge cover 60 is arranged so that the opening frame 61 is in the first direction, when the opening frame 61 is pressed with a finger or the like to tilt the discharge cover 60 forward, the rotating holder 70 rotates with the rotating shaft 43e as the center of rotation. At this time, since the discharge port part 30 is inserted into the insertion hole 71a provided in the top wall surface 71 of the rotating holder 70, the outer peripheral surface of the discharge tube 32 is pressed against the inner surface of the insertion hole 71a, and the discharge port part 30 rotates together with the discharge cover 60. In addition, since the restricting part 74 is provided on the side surface part 72 of the rotating holder 70, it rotates together with the rotating holder 70 and moves to a position where it does not interfere with the upper outer tube 22c. In this way, by tilting the discharge cover 60 by, for example, pressing the opening frame 61 with a finger, the direction of the discharge port 31 and the maximum stroke amount of the press-down head 40 can be easily changed.

According to the discharge pump 100a of the present embodiment described above, when the discharge cover 60 is positioned in the first direction, the contents can be attached to the user's palm or the like by the simple action of pressing the opening frame 61 toward the container body 10 with the palm or the like. Furthermore, any excess contents that do not adhere to the palm or the like will fall into the opening frame 61 or the like. Therefore, if a disinfectant or the like is stored as the contents, the disinfectant will fall onto the discharge cover 60 side each time it is used, and the discharge cover 60 can be kept hygienic.

In addition, in this embodiment, the support part 62 that supports the opening frame 61 relative to the rotating holding part 70 is composed of four plate-shaped members 62a, and there is an opening between each of the plate-shaped members 62a. Therefore, the contents discharged from the discharge port 31 do not accumulate in the discharge cover 60. Therefore, the contents that fall from the palm side when the opening frame 61 is pressed down do not accumulate in the discharge cover 60, and the discharge cover 60 can be maintained hygienic.

Furthermore, in this embodiment, the discharge cover 60 is attached to the press-down head 40 by the rotating holder 70 so that it can be displaced between a first orientation and a second orientation. Therefore, it can be used as a two-way container that can be displaced between a first orientation and a second orientation depending on the usage form. For example, in the first orientation, as described above, the contents can be applied directly to the palm of the hand by placing the palm or the like on the opening frame 61 and pressing it down. In addition, in the second orientation, the pump container 100 can be used like a spray container in which the contents are sprayed in a direction intersecting the axial direction when the head is pressed down, for example.

In addition, in this embodiment, when the discharge cover 60 is displaced to the second orientation, the flat back portion 73 is positioned above the mouth portion 11, and the back portion 73 functions as a second pressing operation portion, so that the pressing operation of the pressing head 40 is easy even in the second orientation.

Furthermore, in this embodiment, as described above, the support portion 62 is composed of four plate-like members 62a, and two of each are attached to the side portion 72 of the rotating holder 70. Therefore, when in the second position, a wide opening can be secured downward in the axial direction. Therefore, when the press-down head 40 is pressed down in the second orientation, when the spray range is widened when spraying the contents from the discharge port 31, the contents can be sprayed to the outside not only from the opening in the center of the opening frame 61 but also from the opening between the plate-like members 62a without being blocked by the support portion 62.

In addition, in this embodiment, a guide groove hole 43c is provided in the upper head portion 43, and the discharge direction of the contents can be easily changed by moving the discharge port portion 30 along the guide groove hole 43c. In this case, in this embodiment, the discharge port portion 30 can be moved along the guide groove hole 43c by the simple operation of tilting and rotating the discharge cover 60. Therefore, unlike conventional 2-way discharge containers, for example, it is not necessary to provide multiple discharge ports 31 and block unused discharge ports 31 with a seal member, and a simple configuration can be achieved.

Furthermore, in this embodiment, the discharge port portion 30 is provided with a rotating tube 33 and a discharge tube 32, and is an L-shaped flow path, and is connected to the stem 52 of the pump mechanism 50 by a flow path portion 45 having a U-shaped flow path. Furthermore, the rotating tube 33 is supported rotatably within the pressing head 40. By adopting this configuration, the distance between the upper end of the stem 52 and the lower end of the discharge port portion 30 can be reduced. For example, if the stem 52 and the discharge port portion 30 are connected by a flexible tube or the like, mechanical stress such as bending of the tube is applied when the direction of the discharge port portion 30 is changed, and it is assumed that the tube will be crushed, making it impossible to smoothly discharge the contents, or the tube will deteriorate. However, in this embodiment, by adopting the above-mentioned configuration, there is no risk of part of the flow path being crushed, and the discharge pump 100a and the pump container 100 can be used well for a long period of time.

The above embodiment is an example of the discharge pump and pump container according to the present invention, and the discharge pump and pump container according to the present invention are not limited to the above embodiment, and can be appropriately modified within the scope of the present invention. For example, in the above embodiment, the opening frame 61 made of a circular flat plate member having a circular opening is used as the first pressing operation part. However, in the discharge pump according to the present invention, the opening frame 61 may be replaced with an opening frame formed in a frame shape of various shapes such as a rectangle, a polygon, or an indefinite shape, which opens axially above the discharge port 31 when the discharge cover 60 is attached in a predetermined direction, and the opening frame may function as the first pressing operation part. In this case, the opening shape and the outer shape of the opening frame do not need to be similar. In other words, the opening frame in the present invention may have a shape different from the opening shape and the outer shape, and the specific shape of the opening frame is not limited. In addition, a part of the opening frame 61 may be cut out, and the shape of the opening frame 61 is not limited to a closed figure shape.

In the above embodiment, the discharge cover 60 is made up of four plate-like members 62a, and an opening is provided between adjacent plate-like members 62a, but the number of plate-like members 62a is not limited to four. If the support part 62 is made up of multiple plate-like members 62a as in the above embodiment, and an opening is provided between adjacent plate-like members 62a, it is possible to prevent the contents from accumulating in the discharge cover 60. However, for example, the top wall surface 71 of the rotating holding part 70, the support part 62, and the opening frame 61 may be formed integrally into a cup or dish shape, and the pump container 100 may be, for example, a so-called hand wrap container in the first orientation.

Furthermore, the specific configuration of the discharge port portion 30 and the pump mechanism 50, etc., are not particularly limited, and conventionally known configurations can be adopted as appropriate. In addition, in the above embodiment, the discharge cover 60 may be configured to be easily detachable from the press head 40 by the rotating holder 70. By configuring the discharge cover 60 to be easily detachable from the press head 40 by the user, the discharge cover 60 can be washed at the desired timing. Therefore, the discharge cover 60 as the operation press portion can be maintained hygienically.

The pump container 100 and the discharge pump 100a can be made of various resin materials used as container packaging materials (for example, polypropylene resin (PP), polyethylene resin (PE) such as low-density polyethylene (LDPE) and high-density polyethylene resin (HDPE), polyethylene terephthalate resin (PET), etc.). The discharge pump 100a and the pump container 100 may be made of a resin material with an antibacterial agent kneaded into it, or the surface may be coated with an antibacterial coating. Furthermore, the container body 10 is not limited to being made of resin, but may be made of glass, metal, etc.
