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.

JP 2019-81592 A

Meanwhile, disinfectants placed at the entrances of various facilities are used by an unspecified number of visitors. The nozzle head is pressed down before disinfecting the hands, so there is a risk of viruses, bacteria, etc. adhering to the nozzle head. Visitors disinfect their hands after pressing down the nozzle head, so the viruses attached to the hands are removed and disinfected by touching the nozzle head. However, the contact area between the nozzle head and the palm of the hand, etc. is relatively large, and since an unspecified number of visitors touch it, it may give the impression of being unsanitary. In addition, it is preferable that the nozzle head is also disinfected and disinfected every time it is used. Furthermore, in these facilities, regular disinfection and disinfection of places that are touched by hands, such as doorknobs and handrails, is required. In such cases, it would be more preferable if the disinfectant dispensed from the container could be easily soaked into paper towels, etc., or if it could be used as a spray, such as by spraying the disinfectant directly onto the disinfected area, etc.

The objective of the present invention is to provide a discharge pump and pump container that are easy to operate and whose depression operation part can be easily maintained in a hygienic manner.

In order to solve the above problem, a discharge pump according to the present invention comprises an attachment part that is attached to the mouth part of a container body that contains contents, a discharge port part having a discharge port for discharging the contents to the outside, a discharge head that holds the discharge port part and is provided on the attachment part so as to be pressable toward the container body along the axial direction of the mouth part, a pump mechanism that sends the contents to the discharge port side as the discharge head is pressed down, and a discharge head cover that is attached in a predetermined orientation to the discharge head and is spaced a predetermined distance from the discharge port in the axial direction and includes a frame-shaped part that opens axially upward relative to the discharge port, and is configured so that when the frame-shaped part is pressed toward the container body along the axial direction with the discharge head cover attached in the predetermined orientation, the discharge head is pressed down and the contents are discharged from the discharge port through the inside of the opening to the outside of the frame-shaped part, and the discharge head cover is detachable from the discharge head, is oriented in the opposite axial direction to the predetermined orientation, and can be attached to the discharge head so that the frame-shaped part abuts against the container body .

Below, a first embodiment and a second embodiment of the discharge pump and pump container according to the present invention will be described with reference to the drawings.

First embodiment
Fig. 1 is a front view of a discharge pump 100a according to a first embodiment, and a part of the discharge pump 100a is shown in cross section. 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 via an attachment portion 20. In the following, a description will be given assuming that the contents are disinfectants such as disinfectant alcohol or a sodium hypochlorite aqueous solution, but the contents can contain various liquids.

The discharge pump 100a includes an attachment part 20 that is attached to the mouth part 11 of the container body 10 that contains the contents, a discharge port part 30 having a discharge port 31 for discharging the contents to the outside, a discharge head 40 that holds the discharge port part 30, a pump mechanism 50 that operates when the discharge head 40 is pressed down, a discharge head cover 60 (discharge cover) that is attached to the discharge head 40, and an attachment part 70 that attaches the discharge head cover 60 to the discharge head 40 so that the position of the discharge head cover 60 can be changed between a first position shown in FIG. 1 and a second position (see FIG. 6) rotated approximately 90 degrees from the first position.

The specific configuration of each part will be described below. In this specification, "upper" and "lower" indicate relative positional relationships, and when the container body 10 is placed in the upright position shown in Figure 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 is referred to as "lower" and the side on which the discharge head 40 is located is referred to as "upper." Additionally, "axial direction" refers to the axial direction of the central axis O of the mouth portion 11 of the container body 10. Additionally, Figure 1 is a front view of the discharge pump 100a and the pump container 100.

The container body 10 comprises a bottom 12, a body 13, a shoulder 14, and the mouth 11, which are integrally constructed. In the example shown in FIG. 1, the body 13 is erected around the bottom 12 and gradually reduces in diameter 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 part 20 is provided with a cylindrical mounting tube 21 that is open at the top and bottom. An inner lid surface 22 is provided at the axial middle position of the mounting tube 21. A female thread 21a is provided on the inner peripheral surface of the mounting tube 21 below the inner lid surface 22. The mounting part 20 is mounted to the mouth part 11 of the container body 10 by screwing this female thread 21a into a male thread 11a provided on the mouth part 11. The inner lid surface 22 is provided with an insertion tube 23 that is connected to a hole that penetrates in the thickness direction and protrudes downward from the underside of the inner lid surface 22. An insertion tube 45 provided on the discharge head 40 and a part of the pump mechanism 50 are inserted into the insertion tube 23 so that they can move up and down in the axial direction. This point will be described later.

It is configured as a spray nozzle that sprays liquid in a mist form from the discharge port 31. The discharge port portion 30 is held by the discharge head 40, and when the discharge head cover 60 is displaced from the first position to the second position, the discharge port portion 30 moves from a first position _P1 corresponding to the first position to a second position _P2 (see FIG. 6) corresponding to the second position. This point will be described later.

The discharge port 30 is connected to the pump mechanism 50 by a bellows-shaped expandable and contractible connecting tube 35. Here, Fig. 2 is a side view of the discharge pump 100a and the discharge pump 100a, with a portion shown as a cross-section. Note that some reference numerals are omitted in Fig. 2. As shown in Fig. 2, the length of the connecting tube 35 is set to a length that allows it to bend sufficiently within the discharge head 40 when the discharge port 30 is held at the first position _P1 .

Refer to FIG. 1 again. As shown in FIG. 1, the discharge head 40 is inserted into the mounting tube 21 so as to be movable up and down in the axial direction. Specifically, it includes a lower cover part 41 that is inserted into the mounting tube 21, an upper cover part 42 to which the discharge head cover 60 is attached via an attachment part 70, a connecting part 43 that connects the lower cover part 41 and the upper cover part 42, and a base part 44 that is housed and held within the lower cover part 41.

The base 44 is formed in a short cylindrical shape with a top. An insertion tube 45 is provided on the top surface of the base 44, which is connected to a hole that penetrates in the thickness direction and protrudes downward from the bottom surface. The insertion tube 45 is inserted into the insertion tube 23 provided in the mounting tube 21 so that it can move up and down along the axial direction.

The lower cover part 41 is formed in a generally cylindrical shape. The lower cover part 41 is configured to be movable up and down in the axial direction within the mounting tube 21 while housing and holding the base part 44. A retaining part 21b that protrudes radially toward the axis is provided at the upper end of the inner peripheral surface of the mounting tube 21, and a retaining part 41a that protrudes radially outward is provided at the lower end of the outer peripheral surface of the lower cover part 41, which prevents the ejection head 40 from coming off the mounting tube 21. In addition, the lower cover part 41 abuts against the upper surface of the middle lid surface 22, thereby restricting the ejection head 40 from moving downward in the axial direction.

As shown in Fig. 1, the upper cover part 42 includes a cylindrical side wall part 42a and a top wall part 42b having a dome-shaped curved surface covering the upper part of the side wall part 42a. The upper cover part 42 is provided with a guide groove 48 that holds the discharge port part 30 and guides the discharge port part 30 to move from a first position _P1 corresponding to the first attitude to a second position _P2 corresponding to the second attitude (see Figs. 2 and 3(b)). The side wall part 42a of the upper cover part 42 is provided with a pair of fitting parts 49 that protrude in a direction substantially perpendicular to the axial direction on both sides thereof in a front view shown in Fig. 1, and a fitting hinge 71a provided on the inner surface of the side part 71 of the mounting part 70 is rotatably fitted into the fitting part 49 (see Fig. 3(a)).

Next, the guide groove 48 will be described with reference to Figures 2 and 3. Figure 3(b) is a cross-sectional view taken along the line CC in Figure 2. Figures 1, 2, and 3(b) show a state in which the discharge port portion 30 is held at a first position _P1 . As shown in Figures 2 and 3(b), the first position _P1 corresponds to a position where the top wall portion 42b intersects with the central axis O. A top wall portion-side through groove 48a having a width approximately equal to the width of the discharge port portion 30 is formed in the top wall portion 42b from a position corresponding to the first position _P1 toward the side wall portion 42a.

The second position _P2 corresponds to the position to which the insertion hole 61a of the bottom surface portion 61 moves when the ejection head cover 60 is rotated approximately 90 degrees about the central axis Q of the fitting portion 49 as the axis of rotation with the fitting hinge 71a fitted into the fitting portion 49 (see FIG. 6). As shown in FIGS. 2 and 3(b), the side wall portion 42a is formed with a side wall portion-side through groove 48c having a width approximately equal to the width of the ejection port portion 30, which is continuous with the top wall portion-side through groove 48a and extends to the second position _P2 . The guide groove 48 is formed by the top wall portion-side through groove 48a and the side wall portion-side through groove 48c.

2 and 3(b), the discharge port portion 30 is inserted into the guide groove 48 from the inside of the upper cover portion 42, and its tip is inserted into the insertion hole 61a provided in the bottom surface portion 61 of the discharge head cover 60 (see FIG. 4). Therefore, when the discharge head cover 60 is rotated so as to tilt from the first position shown in FIG. 2 to the second position shown in FIG. 6, the discharge port portion 30 is pushed by the insertion hole 61a of the bottom surface portion 61 and guided by the guide groove 48, and moves from the first position _P1 to the second position _P2 . Note that, when the discharge head cover 60 is rotated in the opposite direction to return the discharge head cover 60 from the second position to the first position, the discharge port portion 30 also moves from the second position _P2 to the first position _P1 .

The movement of the discharge port portion 30 is restricted at the first position _P1 and the second position _P2 by the following configuration. As shown in the enlarged view of FIG. 3B, a pair of recessed grooves 30a is provided on the outer peripheral surface of the discharge port portion 30. The recessed grooves 30a are provided parallel to the axial direction. The top wall side through groove 48a is provided with a pair of first restricting portions 48b that protrude from the groove surface toward the discharge port portion 30 at the first position _P1 . Therefore, when the discharge port portion 30 moves to the first position _P1 , the movement of the discharge port portion 30 is restricted by the groove surface of the top wall side through groove 48a and the first restricting portions 48b, and the discharge port portion 30 is held at the first position _P1 .

Similarly, the side wall through groove 48c is provided with a pair of second restricting portions 48d that protrude from the groove surface toward the outlet portion 30 at the second position _P2 (see Figs. 2 and 3(b)). Therefore, when the outlet portion 30 moves to the second position _P2 , the movement of the outlet portion 30 is restricted by the groove surface of the side wall through groove 48c and the second restricting portions 48d, and the outlet portion 30 is held at the second position _P2 .

Next, the pump mechanism 50 will be described with reference to Figure 1. The pump mechanism 50 includes a stem 51 formed in a short tube shape, a holder portion 52 connected to the lower end of the stem 51, a piston portion 53 held by the holder portion 52, a cylinder 54 that accommodates the piston portion 53 so that it can move up and down in the axial direction, a suction tube 55 connected to a suction port 54a provided at the lower end of the cylinder 54 and extending toward the bottom portion 12 of the container body 10, and a suction valve 56.

The holder portion 52 has an annular pressing portion 52a that protrudes circumferentially outward from the lower end of the stem 51, and a clamping portion 52b that is suspended from the pressing portion 52a and clamps the head of the piston portion 53. The piston portion 53 has a first piston 53a and a second piston 53b, and is held by the holder portion 52. The piston portion 53 is biased axially upward by a spring.

Next, the mounting structure of the pump mechanism 50 to the container body 10 will be described. The upper end of the cylinder 54 is provided with a flange portion 54b that protrudes outward from its outer circumferential surface. The outer diameter of the flange portion 54b is approximately the same as the outer diameter of the mouth portion 11, and the lower surface of the flange portion 54b abuts against the mouth portion 11 of the container body 10 via a flexible packing 57. When the mounting portion 20 is mounted to the mouth portion 11, the flange portion 54b is sandwiched between the mouth portion 11 and the inner lid surface 22, and the cylinder 54 and the like are held in the container body 10 with the cylinder 54 and the like inserted inside the container body 10.

At this time, the stem 51 and the holder part 52 are positioned above the mouth part 11. The stem 51 is press-fitted into the insertion tube 45 provided on the base part 44 of the discharge head 40, and the stem 51 is held immovable in the axial direction relative to the insertion tube 45. The lower end 45a of the insertion tube 45 abuts against the upper surface of the pressing part 52a of the holder part 52. The holder part 52 is inserted into the insertion tube 23 provided on the inner cover surface 22 of the attachment tube 21 so as to be movable up and down in the axial direction.

Next, the discharge head cover 60 will be described with reference to Figs. 1 and 4. Fig. 4 is a top view of the pump container 100. As shown in Figs. 1 and 4, the discharge head cover 60 has a bottom surface portion 61, a ring-shaped portion (frame-shaped portion) 62 made of an annular plate-shaped member having a substantially circular opening with an inner diameter larger than the outer diameter of the bottom surface portion 61, and a support portion 63 that supports the ring-shaped portion 62 at a predetermined distance in the axial direction relative to the bottom surface portion 61. The bottom surface portion 61 and the ring-shaped portion 62 are supported by the support portion 63 so as to be coaxial. In the first position shown in Fig. 1, the ring-shaped portion 62 is arranged axially upward relative to the bottom surface portion 61. The direction in which the ring-shaped portion 62 is arranged so as to have such a positional relationship is referred to as the predetermined direction in the present invention.

An insertion hole 61a is formed in the center of the bottom surface portion 61. The outlet portion 30 is inserted into the insertion hole 61a with the outlet 31 facing the ring-shaped portion 62. By inserting the tip of the outlet portion 30 into the insertion hole 61a, the outlet 31 and the ring-shaped portion 62 are arranged coaxially with a predetermined distance apart in the axial direction. In addition, as shown in FIG. 4, the ring-shaped portion 62 has a plurality of protrusions 62a on its upper surface that protrude upward. The plurality of protrusions 62a are arranged at predetermined intervals so as to describe a circle coaxial with the ring-shaped portion 62.

In the first embodiment, the support portion 63 is composed of three plate-shaped members 63a in the illustrated example. Both ends of each plate-shaped member 63a are connected to the bottom surface portion 61 and the ring-shaped portion 62, thereby supporting the ring-shaped portion 62 relative to the bottom surface portion 61. The plate-shaped members 63a are arranged at equal intervals when viewed from above (see FIG. 4). In addition, there is an opening between each of the plate-shaped members 63a. Of the three plate-shaped members 63a, one plate-shaped member 63a is positioned above the mounting surface of the container body 10 in the second position (see FIG. 6). Therefore, in the second position, the opening formed between the remaining two plate-shaped members 63a is positioned so as to face upwardly to the mounting surface.

Next, the mounting portion 70 will be described with reference to Figures 1 to 3. The mounting portion 70 is provided so as to surround the upper cover portion 42 by the side portion 71 having the above-mentioned fitting hinge 71a on the inner surface, the front portion 72 provided between the both side portions 71, and the back portion 73. As shown in Figures 2 and 3(a), the front portion 72 is large enough to cover only the top wall portion 42b of the upper cover portion 42. When the discharge head cover 60 is rotated from the first position to the second position, as shown in Figure 6, the front portion 72 abuts against the upper end and the connecting portion 43 of the lower cover portion 41, and functions as a stopper that restricts the rotational movement of the discharge head cover 60. The side portion 71 is of a length and shape that does not interfere with the lower cover portion 41 when the discharge head cover 60 is rotated from the first position to the second position. In the second position, the back surface 73 is disposed above the mouth 11 and has an area large enough to cover the entire surface of the top wall 42b of the upper cover 42 (see FIG. 6). The fitting hinge 71a is formed in a groove shape on the inside of the side surface 71, and its tip opens in a C-shape and fits rotatably into the fitting portion 49 as described above (see FIGS. 3(a) and (c)). As shown in FIGS. 2 and 3(a), the back surface 73 is disposed so as to be spaced apart from the back side of the upper cover 42.

Next, the operation of the discharge pump 100a will be described with reference to Figures 5 and 6. Note that some reference numerals are omitted in Figures 5 and 6.
As shown in FIG. 5, when the discharge head cover 60 is arranged to be in the first position, the ring-shaped portion 62 functions as a first pressing operation portion. When the ring-shaped portion 62 is pressed axially with the palm of the hand or the like, the discharge head 40 is pressed down. With this operation, the base portion 44 moves axially downward, and the stem 51 and the holder portion 52 move axially downward together with the base portion 44. Then, the piston portion 53 is pressed axially downward, and the pump mechanism 50 is operated. The contents sucked up by the pump mechanism 50 are delivered to the discharge port portion 30 side through the connecting tube 35. The discharge port 31 faces the ring-shaped portion 62. In addition, the contents are discharged with a predetermined momentum imparted by the pump mechanism 50. Therefore, the contents are sprayed upward while expanding in diameter from when they were discharged from the discharge port 31. The sprayed contents pass through the inside of a circular opening provided at approximately the center of the ring-shaped portion 62 and are ejected above (outside) the ring-shaped portion 62, and the contents adhere to the palm of the hand, etc., that is pressing down on the ring-shaped portion 62.

On the other hand, as shown in Fig. 6, when the discharge head cover 60 is arranged to be in the second position, the back surface portion 73 functions as a second pressing operation portion. For example, as shown in Fig. 6, when the back surface portion 73 is pressed in the axial direction with a finger or the like, the discharge head 40 is pressed down. In the second position, the discharge port portion 30 is guided by the guide groove 48 and held at the second position _P2 , and the discharge port 31 faces in a direction substantially perpendicular to the axial direction. Therefore, in the second position, the content delivered from the pump mechanism 50 is sprayed in a direction substantially perpendicular to the axial direction.

According to the discharge pump 100a of the first embodiment described above, when the discharge head cover 60 is arranged in the first position, the contents can be attached to the palm of the user's hand or the like by a simple action of pressing the ring-shaped portion 62 toward the container body 10 with the palm of the user's hand or the like. In this case, by making the first pressing operation portion into the ring-shaped portion 62, the contact area between the pressing operation portion and the palm can be made smaller than when the pressing operation portion is configured in a circular flat plate shape. Therefore, the adhesion area of dirt, viruses, etc. transferred from the operator to the pressing operation portion during operation is reduced. In addition, the work of wiping them off after operation is also simplified. For these reasons, it is easy to keep the pressing operation portion hygienic. Furthermore, excess contents that do not adhere to the palm of the user's hand or the like fall onto the ring-shaped portion 62 or the like. Therefore, if a disinfectant or the like is stored as the contents, the disinfectant falls onto the side of the discharge head cover 60 each time it is used, and the discharge head cover 60 can be kept hygienic.

In this embodiment, multiple protrusions 62a are provided on the upper surface (pressing surface) of the ring-shaped portion 62 in the first position. This allows the contact area with the palm to be reduced. Furthermore, the protrusions 62a act as a slip prevention device, allowing the ring-shaped portion 62 to be pressed downward in a stable manner.

In addition, in this embodiment, the support portion 63 that supports the ring-shaped portion 62 against the bottom portion 61 is composed of three plate-shaped members 63a. Therefore, the contents discharged from the discharge port 31 do not accumulate in the discharge head cover 60. Therefore, the contents that fall from the palm side when the ring-shaped portion 62 is pressed down do not accumulate in the discharge head cover 60, and the discharge head cover 60 can be kept hygienic.

Furthermore, in this embodiment, the discharge head cover 60 is attached to the discharge head 40 by the attachment portion 70 so as to be displaceable between a first position and a second position. Therefore, it can be used as a two-way container that can be displaced between the first position and the second position depending on the usage form. For example, in the first position, the contents may be applied directly to the palm of the hand that presses the container as described above, or the contents may be applied to an applicator such as a paper towel as in a hand wrap container. In addition, in the second position, 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, for example.

In addition, in this embodiment, when the ejection head cover 60 is displaced to the second position, 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 ejection head 40 can be easily pressed down even in the second position.

Furthermore, in this embodiment, as described above, the support portion 63 is composed of three plate-shaped members 63a, and in the second position, one plate-shaped member 63a is positioned axially above the mounting surface of the container body 10, and a wide opening between the remaining two plate-shaped members 63a can be secured above the mounting surface. Therefore, when the discharge head 40 is pressed down in the second position, the spray range when spraying the contents from the discharge port 31 is widened, and the contents can be sprayed to the outside from the opening in addition to the ring-shaped portion 62 without being blocked by the support portion 63.

Furthermore, in this embodiment, the guide groove 48 is provided in the upper cover part 42, and the discharge port part 30 is moved along the guide groove 48 from the first position _P1 corresponding to the first attitude to the second position _P2 corresponding to the second attitude, so that the direction in which the contents are discharged can be easily switched. At that time, in this embodiment, the discharge port part 30 can be moved along the guide groove 48 by a simple operation of tilting and rotating the discharge head cover 60. Therefore, as in the conventional 2-way discharge container, for example, it is not necessary to provide a plurality of discharge ports 31 and block the unused discharge ports 31 with a seal part, and a simple configuration can be achieved. In addition, when blocking the discharge port 31 with a seal part, a configuration in which the seal part is rotated is generally adopted. In this case, since it is necessary to rotate the seal part in a narrow space, the operation of rotating the seal part may be difficult or may require force. On the other hand, according to the above configuration, as described above, the discharge port part 30 can be moved along with the rotation of the discharge head cover 60 by simply pressing the ring-shaped part 62 with a light force, so this switching operation is also simple.

Furthermore, in this embodiment, the discharge port portion 30 and the pump mechanism 50 are connected by a bellows-shaped expandable connecting tube 35. The connecting tube 35 is also made long enough to bend sufficiently inside the discharge head 40. Therefore, the movement of the discharge port portion 30 during the change between the first and second positions is not hindered. In addition, when the discharge port portion 30 is moved, a load is applied to the connecting portion between the discharge port portion 30 and the connecting tube 35 and the connecting portion between the pump mechanism 50 and the connecting tube 35 (the insertion portion with the stem 51), which prevents the connecting tube 35 from being crushed and bent at a right angle, suppressing deterioration of the connecting tube 35 due to repeated switching between the first and second positions, and suppressing a state in which the connecting tube 35 is crushed and the contents cannot move to the discharge port 31 side.

The above-mentioned first 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-mentioned embodiment, and can be appropriately modified within the scope of the present invention. For example, in the above-mentioned embodiment, a ring-shaped portion made of a circular flat plate member having a circular opening is used as the first pressing operation portion. However, in the discharge pump according to the present invention, the ring-shaped portion 62 may be replaced with a frame-shaped portion 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 head cover 60 is attached in a predetermined direction, and the frame-shaped portion may function as the first pressing operation portion. In this case, the frame-shaped portion does not need to have a similar opening shape and outer shape. In other words, the frame-shaped portion according to the present invention may have a shape different from the opening shape and outer shape, and the specific shape of the frame-shaped portion is not limited.

In the above embodiment, the discharge head cover 60 is made of three plate-like members 63a, and the space between the adjacent plate-like members 63a is an opening, but the number of plate-like members 63a is not limited to three, and the number is not limited. If the support portion 63 is made of multiple plate-like members 63a as in the above embodiment, and the space between the adjacent plate-like members 63a is an opening, it is possible to prevent the contents from accumulating in the discharge head cover 60. However, the bottom portion 61, the support portion 63, and the ring-like portion 62 may be formed integrally into a cup shape or a dish shape. In addition, in this case, the support portion may be configured to support the space between the bottom portion 61 and the ring-like portion 62 by providing a mesh shape or a large number of holes, and the support portion may be provided with multiple openings, so that the ring-like portion 62 is positioned axially above the discharge port 31 while preventing the contents discharged from the discharge port 31 from accumulating in the discharge head cover 60, thereby obtaining the same effect as above.

Furthermore, the specific configuration of the discharge port portion 30 and the pump mechanism 50 are not particularly limited, and conventionally known configurations can be adopted as appropriate. In the above embodiment, the discharge head cover 60 may be configured to be easily detachable from the discharge head 40 by the attachment portion 70. By configuring the discharge head cover 60 to be easily detachable from the discharge head 40 by the user, the discharge head cover 60 can be washed at the desired timing. Therefore, the discharge head cover 60 as an operation depression portion can be kept hygienic.

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.

Second Embodiment
Next, a pump container 200 and a discharge pump 200a according to a second embodiment will be described with reference to Figures 7 to 12. Figures 7 and 8 are front views of the pump container 200 according to the second embodiment, with Figure 7 showing a state in which a discharge head cover 90 is attached to a discharge head 80 in a predetermined direction according to the present invention, and Figure 8 showing a state in which the discharge head cover 90 is attached in the opposite direction in the axial direction.

First, referring to FIG. 7, the pump container 200 and the discharge pump 200a of the second embodiment are described. As shown in FIG. 7, the pump container 200 includes a container body 210 and a discharge pump 200a attached to the mouth 211 of the container body 210 via an attachment part 25. The discharge pump 200a includes the attachment part 25, a discharge port part 30 having a discharge port 31 for discharging the contents to the outside, a discharge head 80 that holds the discharge port part 30, a pump mechanism 50 that operates in response to a pressing operation of the discharge head 80, and a discharge head cover 90 that is attached to the discharge head 80. The discharge head cover 90 includes a ring-shaped part 92. In the pump container 200 and the discharge pump 200a of the second embodiment, the discharge head cover 90 is configured to be detachable from the discharge head 80 by rotating it around an axis.

The pump container 200 and the discharge pump 200a are also configured so that when the discharge head cover 90 is attached to the discharge head 80 in a predetermined direction, the ring-shaped portion 92 is pressed toward the container body 210 along the axial direction, thereby pressing down the discharge head 80, and the contents contained in the container body 210 are sprayed from the discharge port 31 through the inside of the opening of the ring-shaped portion 92 to the outside of the ring-shaped portion 92 (see FIG. 11). Also, in the pump container 200 of the second embodiment, when the discharge head cover 90 is attached in a predetermined direction, it is possible to displace between a first position in which the discharge port 31 and the ring-shaped portion 92 are arranged so as to be coaxial, and a second position (see FIG. 12) rotated approximately 90 degrees from the first position, and in the second position, the contents are sprayed in a direction approximately perpendicular to the axial direction.

In addition, in the pump container 200 and the discharge pump 200a, as shown in FIG. 8, the discharge head cover 90 can be attached to the discharge head 80 in the "opposite direction" in the axial direction from the "predetermined direction" shown in FIG. 7. Note that in the second embodiment, the "predetermined direction" refers to the direction in which the ring-shaped portion 92 is positioned above the discharge port 31 when the ring-shaped portion 92 and the discharge port 31 are arranged coaxially.

In the pump container 200 and the discharge pump 200a, the discharge head cover 90 is detachably attached to the discharge head 80, and therefore the configuration of the discharge head 80 and the discharge head cover 90 differs in part from the pump container 100 and the discharge pump 100a of the first embodiment. The following mainly describes the differences in configuration from the first embodiment. Note that the same names and reference symbols are used for components that are substantially the same as those in the first embodiment, such as the discharge port portion 30 and the pump mechanism 50, and description thereof is omitted. Also, in Figures 7 to 12, some reference symbols are omitted for components that are substantially the same as those in the first embodiment.

The mounting part 25 will be described with reference to Figure 7. The mounting part 25 includes a cap part 26 that is mounted on the mouth part 211 of the container body 210, an insertion tube 27 provided below the top surface 26a of the cap part 26, a mounting tube 28 provided above the cap part 26, and an overcap part 29 that is mounted on the cap part 26.

The cap portion 26 is formed in a short cylindrical shape with a top, and a female thread (not shown) provided on the inner surface of the outer periphery of the cap portion 26 screws into a male thread 211a provided on the mouth portion 211 of the container body 210, thereby attaching the attachment portion 25 to the mouth portion 11 of the container body 210. The top surface 26a has an annular shape with an opening in the center.

The insertion tube 27 is connected to the opening of the top surface 26a of the cap portion 26 and is arranged to hang down inside the mouth portion 211 of the container body 210. A part of the pump mechanism 50 is inserted into the insertion tube 27 so that it can move up and down in the axial direction.

The mounting tube 28 is erected on the upper surface of the top surface 26a. The outer diameter of the mounting tube 28 is smaller than that of the cap portion 26, but larger than that of the insertion tube 27. A part of the discharge head 80 is inserted into the mounting tube 28 so that it can move up and down in the axial direction. A retaining portion 28a is provided at the upper end of the mounting tube 28, which prevents the discharge head 80 from falling out. The overcap portion 29 is an overcap that covers the cap portion 26 and part of the mounting tube 28, and the cap portion 26 is fitted into the lower portion of the overcap portion 29.

Next, the configuration of the discharge head 80 will be described. The discharge head 80 includes a lower cylindrical portion 81 that is inserted into the mounting tube 28 so as to be movable up and down in the axial direction, an upper cylindrical portion 82 that is connected to the lower cylindrical portion 81, and a rotor 85 that is rotatably attached to the upper cylindrical portion 82.

The lower cylindrical portion 81 is formed in a short cylindrical shape with a top, and a stopper portion 81a is provided at its lower end. When the lower cylindrical portion 81 moves axially upward relative to the mounting tube 28, the stopper portion 81a and the stopper portion 28a provided on the mounting tube 28 restrict the movement of the lower cylindrical portion 81 and prevent it from falling off. In addition, a hole is provided in the thickness direction at approximately the center of the top surface 81b of the lower cylindrical portion 81. An annular fitting groove 81c that protrudes downward so as to surround the periphery of this hole is provided on the lower surface of the top surface 81b of the lower cylindrical portion 81. The stem 51 of the pump mechanism 50 is press-fitted into the annular fitting groove 81c. In addition to the stem 51, the pump mechanism 50 is provided with a holder portion 52 connected to the lower end of the stem 51, as in the first embodiment, and a piston portion 53. In the second embodiment, the pump mechanism 50 is provided with a seal member 58 that is interposed between the outer surface of the holder portion 52 and the inner surface of the lower cylindrical portion 81.

The upper cylindrical portion 82 is formed in a cylindrical shape with the same diameter as the lower cylindrical portion 81, and is connected to the outer peripheral surface of the lower cylindrical portion 81. The outer peripheral surface of the upper cylindrical portion 82 is provided with a pair of fitting portions 82a that protrude radially outward.

Next, the rotating body 85 will be described with reference to Figures 7, 9, and 10(a). Figure 9(a) is a top view of the rotating body 85, (b) is a cross-sectional view taken along the line D-D in (a), (c) is a bottom view, (d) is a cross-sectional view taken along the line E-E in (a), and (e) is a view showing the rotating body 85 rotated approximately 90 degrees about the central axis Q of the fitting portion 82a of the upper cylindrical portion 82. Figure 10(a) shows the engagement state of the ejection head 80 and the ejection head cover 90, and is a cross-sectional view taken along the line A-A in Figure 7.

As shown in Fig. 7, 9(a) and 9(b), etc., the rotating body 85 has a side wall portion 85a formed in a cylindrical shape with a larger diameter than the upper cylindrical portion 82, and a top wall portion 85b having a dome-shaped curved surface that covers the upper portion of the side wall portion 85a. As shown in Figs. 9(a) and 9(b), a part of the side wall portion 85a is cut out so that the side wall portion 85a does not interfere with the upper cylindrical portion 82 and the lower cylindrical portion 81 when the rotating body 85 is rotated from the first position shown in Figs. 7 and 9(b) to the second position shown in Figs. 9(d) and 12.

As shown in Figs. 7 and 9(b), the inner peripheral surface of the side wall portion 85a is provided with a fitting hinge 85c to which the fitting portion 82a (see Figs. 7 and 10(a)) is rotatably fitted. As shown in Fig. 9(b), a guide groove 85d is provided axially below the fitting hinge 85c. The guide groove 85d has a gradually wider groove width axially below. When assembling the discharge pump 200a, the fitting portion 82a is positioned to be inserted into the guide groove 85d, and the rotor 85 is placed over the upper cylindrical portion 82 and pressed downward, whereby the fitting portion 82a is rotatably fitted into the fitting hinge 85c as described above.

9(a)-(e), a holding portion 85e is provided in the approximate center of the top wall portion 85b, into which the discharge port portion 30 is inserted and held. As shown in FIG. 7, the discharge port portion 30 is pressed into the holding portion 85e and held by the holding portion 85e. Also, as shown in FIG. 9(c), a plurality of reinforcing ribs 85f are provided on the inner surface of the top wall portion 85b, which extend radially from the periphery of the holding portion 85e toward the side wall portion 85a. Furthermore, as shown in FIG. 9(a) and other figures, the outer peripheral surface of the side wall portion 85a is provided with two engaging protrusions 86a and 86b with which the locking claws 91a and 91b of the discharge head cover 90 engage (see FIG. 10(a) and (b)). The sizes of the two engaging protrusions 86a and 86b are different. By rotating and inserting each of the engagement protrusions 86a, 86b into the corresponding locking claws 91a, 91b, the engagement protrusions 86a, 86b engage with the recesses 91c, 91d provided on the locking claws 91a, 91b, respectively.

Next, the discharge head cover 90 will be described with reference to Figures 7, 8, and 10. Figure 8 is a front view showing the discharge head cover 90 attached to the discharge head 80 so that the discharge head cover 90 is oriented in the opposite direction to the above-mentioned predetermined direction, Figure 10(b) shows the locking claws 91a and 91b, and Figure 10(c) is a top view of the pump container 200 when the discharge head cover 90 is attached to the discharge head 80 so that the discharge head cover 90 is oriented in the predetermined direction. The discharge head cover 90 is formed in a cylindrical shape and has a cylindrical mounting cover part 91 that is inserted onto the discharge head 80, a ring-shaped part (frame-shaped part) 92, and a support part 93 composed of three plate-shaped members 93a.

When the discharge head cover 90 is attached to the discharge head 80 in a predetermined direction, the discharge port 31, the mounting cover part 91, and the ring-shaped part 92 are positioned so as to be coaxial, as shown in FIG. 7. As in the first embodiment, the upper surface of the ring-shaped part 92 is provided with a plurality of protrusions 92a that protrude upward (see FIG. 10(c)). Although the ring-shaped part 92 and the support part 93 have some differences in their specific shapes, they have substantially the same configuration, action, and effect as the ring-shaped part 62 and the support part 63 of the first embodiment. However, in the second embodiment, since there is no bottom part 61 as in the first embodiment, the support part 93 is connected to the mounting cover part 91 and the ring-shaped part 92.

As shown in Figures 10(a) and (b), the above-mentioned locking claws 91a and 91b are provided on the inner surface of the lower part 91e of the mounting cover part 91. In addition, the upper part 91f of the mounting cover part 91 has a larger diameter than the lower part 91e. When the discharge head cover 90 is attached to the discharge head 80 in a predetermined direction, as described above, the locking claws 91a and 91b are engaged with the engaging protrusions 86a and 86b, respectively, and the lower end of the lower part 91e abuts against the step part 85g (see Figures 7, 8, 9(b) and (d)) that is provided on the lower part of the rotor 85 and has a larger diameter radially outward.

In the second embodiment, as shown in FIG. 8, the discharge head cover 90 can be attached to the discharge head 80 in the axial direction opposite to the specified direction. At this time, the mounting cover part 91 is inserted onto the rotating body 85, and the rotating body 85 is pressed against it by the lower part 91e of the mounting cover part 91. In addition, the ring-shaped part 92 is fitted into the fitting groove 213 provided in the shoulder part 212 of the container body 210. By attaching the discharge head cover 90 to the discharge head 80 in the opposite direction in this way, the discharge head cover 90 can function as a stopper to prevent the discharge head 80 from being pushed in.

Next, the operation of the discharge pump 200a will be described with reference to FIG. 11. Note that some reference numerals are omitted in FIG. 11. FIG. 11 shows a state in which the discharge head cover 90 is attached to the discharge head 80 in a predetermined direction and arranged to be in a first position. In the first position, the ring-shaped portion 92 functions as a first pressing operation portion, as in the first embodiment. When the ring-shaped portion 92 is pressed in the axial direction with the palm of the hand or the like, the discharge head 80 is pushed axially downward. At this time, the stem 51 of the pump mechanism 50 is pressed into the annular fitting groove 81c provided in the lower cylindrical portion 81, so that the pump mechanism 50 is operated and the contents are sucked up. The sucked up contents are sent to the discharge port portion 30 side through the connecting tube 35 and sprayed upward from the discharge port 31.

On the other hand, as shown in FIG. 12, when the ring-shaped portion 92 of the discharge head cover 90 is rotated so as to tilt it, the rotating body 85 rotates about the central axis Q (see FIG. 12) of the fitting portion 82a (see FIG. 7) provided on the upper cylindrical portion 82 as the rotation axis, and the discharge head cover 90 rotates approximately 90 degrees. When the discharge head cover 90 is positioned so as to assume this second position, a part of the mounting cover portion 91 of the discharge head cover 90 functions as a second pressing operation portion. In this second position, the contents delivered from the pump mechanism 50 are sprayed in a direction approximately perpendicular to the axial direction.

As for the discharge pump 200a of the second embodiment described above, the discharge head cover 90 can be displaced between a first position and a second position depending on the mode of use, and used as a two-way container, and in the first position, the ring-shaped portion 92 can be used as a pressing operation portion. Therefore, it is possible to obtain substantially the same effect as the first embodiment.

On the other hand, in the second embodiment, the rotating body 85 is rotatably provided relative to the upper cylindrical portion 82, and the ejection head cover 90 is detachably attached to the rotating body 85. Therefore, in this embodiment, the ejection head cover 90 can be simply configured. Also, the user can remove the ejection head cover 90 at a desired timing and wash the ejection head cover 90. Therefore, compared to the first embodiment, the ejection head cover 90 can be kept more hygienically.

Furthermore, in this embodiment, as shown in FIG. 8, the discharge head cover 90 can be attached to the discharge head 80 in the axial direction opposite to the above-mentioned predetermined direction. At this time, the ring-shaped portion 92 is fitted into the fitting groove 213 provided in the shoulder portion 212 of the container body 210, so that the discharge head 80 cannot be pressed down. By making it function as a stopper in this way, it is possible to prevent the discharge head 80 from being accidentally pressed down during distribution, sale, or when not in use, and the contents from being discharged to the outside. Furthermore, by attaching the discharge head cover 90 in the opposite direction to the discharge head 80 in this way when not in use or when packaged for distribution, the pump container 200 can be made more compact in the axial direction compared to when it is in use. Therefore, the space required for storage or packaging can be reduced.

The second embodiment is also 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 various modifications such as those described in the first embodiment are possible within the scope of the present invention. In the second embodiment, the discharge head cover 90 is configured to be detachable from the discharge head 80 by rotating it around an axis, but the method of detachably attaching the discharge head cover 90 to the discharge head 80 is not limited to the above method. In addition, as in the second embodiment, if the discharge head cover 90 is configured to be detachable from the discharge head 80 in the opposite direction to the above-mentioned predetermined direction, it can be used as the stopper, which is preferable, but the present invention is not limited to this. The discharge head cover 90 may be configured to be simply detachable from the discharge head 80.
