In the first posture shown in FIG. 1, the discharge port portion 30 is inserted into the insertion hole 71a so that the discharge surface of the discharge port 31 faces the ring-shaped portion (opening frame) 61 side of the discharge cover 60. In the first posture, the insertion hole 71a, the discharge port 31, and the opening 61a of the ring-shaped portion 61 are arranged coaxially with the central axis O. Even in the second posture shown in FIGS. 6 (b) and 8, the insertion hole 71a, the discharge port 31, and the opening 61a of the ring-shaped portion 61 are maintained in a coaxially arranged state. However, in the second posture, these are arranged in a direction substantially orthogonal to the central axis O.

As shown in FIGS. 1 and 5A, the side surface portion 72 is provided with the bearing hole 72a, and the rotating shaft portion 43d is inserted into the bearing hole 72a. The side surface portion 72 and the back surface portion 73 are provided so as to surround the upper head portion 43 from three sides. The mounting portion 70 is mounted on the upper head portion 43 so as to be rotatable approximately 90 degrees from the first posture shown in FIG. 7 to the second posture shown in FIG. 8 with the rotating shaft portion 43d as the rotation center. Further, as shown in FIG. 8, when the mounting portion 70 rotates to the second posture, the end portion of the top wall surface 71 comes into contact with the top wall surface of the lower head portion 42, and further rotation is restricted. Further, in the second posture, the back surface portion 73 is arranged above the mouth portion 11 in the axial direction. The back surface portion 73 has an area sufficient to cover the entire surface of the top wall portion 43b of the upper head portion 43 in the second posture.

As shown in FIG. 1, the discharge cover 60 has a ring-shaped portion 61 having an opening 61a arranged axially upward with respect to the insertion hole 71a provided in the top wall 71 of the mounting portion 70 in the first posture. It has a support portion 62 that supports the ring-shaped portion 61 with respect to the top wall surface 71 of the mounting portion 70. As shown in FIG. 5A, the ring-shaped portion 61 is formed of an annular plate-shaped member. Further, as shown in FIG. 1 and the like, the ring-shaped portion 61 is not flat and has a plurality of convex portions 61b, some of which project upward in a wavy shape in a side view. In the present embodiment, the ring-shaped portion 61 has four convex portions 61b.

Next, the configuration of the discharge cover 60 will be described in more detail with reference to FIG. As shown in FIG. 6A, the opening 61a of the ring-shaped portion 61 is arranged above the predetermined distance L1 in the axial direction from the insertion hole 71a provided in the top wall surface 71 of the mounting portion 70. The predetermined distance L1 is set to be 30 mm or less. The predetermined distance L1 refers to the separation distance between the insertion hole 71a and the opening 61a on the central axis O. The distance L1 is a value measured as follows. The insertion hole 71a is a through hole provided in the top wall surface 71 and is open. The upper surface of the opening is closed with a virtual surface orthogonal to the central axis O at the upper end opening edge of the insertion hole 71a. Similarly, the lower end opening edge of the opening 61a of the ring-shaped portion 61 is closed with a virtual surface orthogonal to the central axis O on the lower surface of the opening. The distance on the central axis O between the two virtual surfaces at this time is defined as the predetermined distance L1. When this predetermined distance L1 is 30 mm or less, the entire pump mechanism 50 is compact so that the heights of the discharge pump 100a and the pump container 100 in the axial direction do not become too high while ensuring a stroke for driving the pump mechanism 50. Can be configured in. In order to obtain the discharge pump 100a and the pump container 100 that are more compact as a whole, the predetermined distance L1 is more preferably 28 mm or less, and further preferably 25 mm or less. In the present embodiment, the outer peripheral edge of the upper end of the discharge surface of the discharge port 31 and the upper end opening edge of the insertion hole 71a are arranged at substantially the same height in the axial direction, but the discharge surface of the discharge port 31 is arranged. The discharge port portion 30 may be inserted into the insertion hole 71a so as to project upward in the axial direction from the upper end opening edge of the insertion hole 71a, or the discharge surface of the discharge port 31 may be more shaft than the upper end opening edge of the insertion hole 71a. The discharge port portion 310 may be inserted into the insertion hole 71a so as to be arranged slightly downward in the direction. The predetermined distance L1 is the distance between the insertion hole 71a and the opening 61a (opening surface) of the ring-shaped portion 61 regardless of the position of the discharge surface of the discharge port 31.

Further, when the discharge cover 60 is rotated from the first posture to the second posture, as shown in FIG. 6B, a part of the inner surface of the ring-shaped portion 61 and the outer cylinder 22 of the mounting portion 20 are continuously provided. The outer peripheral surfaces of the portion 22b and the lower outer cylinder 22a face each other. In the discharge pump 100a and the pump container 100 of the present embodiment, the distance L2 between the inner surface of the ring-shaped portion 61 and the outer peripheral surface of the outer cylinder 22 is secured to be 10 mm or more in the second posture. As shown in FIG. 8, in the second posture, when the back surface portion 73 of the mounting portion 70 is pressed with a finger, the vicinity of the continuous portion 22b of the mounting portion 20 is gripped by the finger. At that time, if the distance L2 is less than 10 mm, it becomes difficult to grip the mounting portion 20 with a finger, or the gripped finger abuts on the ring-shaped portion 61 and the back surface portion is gripped with the mounting portion 20. Operability is reduced, such as the inability to press 73. The distance L2 also changes depending on the outer diameter of the outer cylinder 22 of the mounting portion 20 and the like. By setting the predetermined distance L1 to 30 mm or less and the distance L2 to 10 mm or more, preferably 15 mm or more, operability in the second posture can be ensured. Further, in the present embodiment, as shown in FIG. 6B, the convex portion 61b of the ring-shaped portion 61 is provided at a position facing the outer peripheral surface of the outer cylinder 22 in the second posture. As a result, it becomes easy to set the predetermined distance L2 to 10 mm or more while setting the predetermined distance L1 to 30 mm or less. When the predetermined distance L1 is 30 mm, even if the ring-shaped portion 61 has a flat plate shape, that is, even if the convex portion 61b is not provided, a space for gripping the mounting portion 20 with a finger is secured. be able to.

Further, as shown in FIG. 6C, it is assumed that the inner diameter D1 of the opening 61a of the ring-shaped portion 61 is 40 mm or more and 85 mm or less. While maintaining the opening 61a of the ring-shaped portion 61 so as not to become too large, as shown in FIG. 7, when the ring-shaped portion 61 is pressed with the palm or the like in the first posture, the ring-shaped portion 61 is pressed from the child's hand to the adult's hand. The contents can be satisfactorily adhered to the palm or the like with a relatively wide adhesion area while having an easy size. The inner diameter D1 of the opening 61a of the ring-shaped portion 61 is more preferably 50 mm or more and 70 mm or less, and further preferably 55 mm or more and 65 mm or less. However, in the present embodiment, the opening 61a of the ring-shaped portion 61 has a circular shape, and the inner diameter D1 and the inner diameter D2 shown in FIG. 6C have the same length. When the opening 61a has an indefinite shape, it is preferable that both the minimum inner diameter and the maximum inner diameter passing through the central axis O are within the above range.

Further, when the ring-shaped portion 61 is viewed from above, the width W of the ring ring forming the ring-shaped portion 61 (see FIG. 6C) is preferably 3 mm or more. As shown in FIG. 7, when the ring-shaped portion 61 is pressed by the palm in the first posture, if the width W is too small, it is assumed that the ring-shaped portion 61 bites into the palm. When this width W is 3 mm or more, it is possible to suppress biting into the palm when the ring-shaped portion 61 is pressed. Therefore, even when the child is operated with a soft hand, the operability can be improved without causing the child to feel pain. In the present embodiment, the outer edge end and the inner edge end of the ring ring of the ring-shaped portion 61 are rounded with a predetermined curvature so that the palm does not bite into the corner portion during the pressing operation. Further, when the width W of the ring ring forming the ring-shaped portion 61 is not constant, the minimum width thereof is preferably 3 mm or more.

As the material of the ring-shaped portion 61, polypropylene resin (PP), ABS resin, polyacetal resin (POM (polyoxymethylene resin)), polyethylene terephthalate resin (PET), high-density polyethylene resin (HDPE) and the like can be preferably used. can. Since each of the listed resins has high strength, the ring-shaped portion 61 (and the entire discharge cover 60) is formed of these resins to reduce the thickness, and the width W can be set to 2 mm to 3 mm. It is possible to impart durability to withstand repeated pressing operations.

Next, the support portion 62 will be described. As shown in FIG. 5A, in the present embodiment, the support portion 62 is composed of four plate-shaped members 62a. Both ends of each plate-shaped member 62a are connected to the side surface portion 72 of the mounting portion 70 and the ring-shaped portion 61 to support the ring-shaped portion 61 with respect to the mounting portion 70 (FIGS. 1, 7, etc.). reference). Further, as shown in FIGS. 5A and 7 and the like, two plate-shaped members 62a are attached to the side surface portion 72, and are adjacent to each other on the front surface side and the back surface portion 73 side of the attachment portion 70. There is a large opening between the plate-shaped members 62a.

Next, the operation of the discharge pump 100a will be described with reference to FIGS. 7 and 8. Note that some reference numerals are omitted in FIGS. 7 and 8. As shown in FIG. 7, when the discharge cover 60 is arranged so as to be in the first posture, the ring-shaped portion 61 functions as the first pressing operation portion. When the ring-shaped portion 61 is pressed in the axial direction with the palm of the hand or the like, the pressing head 40 moves downward in the axial direction. As the push head 40 moves, the stem 52 moves downward in the axial direction, and the pump mechanism 50 operates. The contents sucked up by the pump mechanism 50 are sent out axially upward through the flow path (arrow a) shown in FIG. 6A via the stem 52 and the fitting tube 41a. Then, as shown in FIG. 6A, the content storage portion 44c in the rotating cylinder holding portion 44 is pivoted via the flow path (arrow b) in the support base 44a at the upper end of the fitting insertion cylinder 41a. It is sent upward in the direction (arrow c). Then, it is delivered in the radial direction by the flow path (arrow d) in the thin tube portion 33a of the rotating cylinder 33. Then, the contents flowing into the discharge cylinder 32 are delivered upward in the axial direction (arrow e) toward the discharge port 31. The discharge port 31 faces the ring-shaped portion 61. Further, the contents are discharged in a state where a predetermined momentum is applied by the pump mechanism 50. Therefore, the contents are sprayed upward while increasing the diameter as compared with the case where the contents are discharged from the discharge port 31. Then, the sprayed contents were discharged above (outside) the ring-shaped portion 61 while passing through the inside of the circular opening 61a provided in the substantially center of the ring-shaped portion 61, and pressed the ring-shaped portion 61. The contents adhere to the palm of the hand.

On the other hand, as shown in FIG. 8, when the discharge cover 60 is arranged so as to be in the second posture, the back surface portion 73 functions as the second pressing operation portion. For example, when the back surface portion 73 is pressed in the axial direction with a finger or the like, the pressing head 40 is pushed down. In the second posture, the discharge port portion 30 is guided by the guide groove hole 43c and is arranged at the second position shown in FIG. That is, the discharge port 31 faces in the radial direction. Therefore, in the second posture, the contents delivered from the pump mechanism 50 are sprayed in the radial direction.

According to the discharge pump 100a of the present embodiment described above, when the discharge cover 60 is arranged so as to be in the first posture, the ring-shaped portion 61 is simply pressed toward the container body 10 by the palm of the user or the like. The contents can be attached to the palm or the like with various movements. At that time, by forming the first pressing operation portion as a ring-shaped portion 61, the contact area between the pressing operation portion and the palm can be reduced as compared with the case where the pressing operation portion is configured in a circular flat plate shape. can. Therefore, the area where dirt, viruses, and the like are transferred from the operator to the pressing operation unit during operation is reduced. In addition, the work of wiping them off after the operation becomes simple. From these things, it is easy to hygienically hold the pressing operation unit. Further, the excess contents that did not adhere to the palm or the like fall onto the ring-shaped portion 61 or the like. Therefore, if the disinfectant solution or the like is contained as the content, the disinfectant solution drops on the discharge cover 60 side each time it is used, and the discharge cover 60 can be hygienically held.

In the present embodiment, a convex portion 61b is provided on the upper surface (pressing surface) of the ring-shaped portion 61 in the first posture so as to project upward in a wave shape in a side view. Therefore, the contact area with the palm can be made smaller.

Further, in the present embodiment, the support portion 62 that supports the ring-shaped portion 61 with respect to the mounting portion 70 is composed of four plate-shaped members 62a, and there is an opening between 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 dropped from the palm side when the ring-shaped portion 61 is pressed are not stored in the discharge cover 60, and the discharge cover 60 can be hygienically held.

Further, in the present embodiment, the discharge cover 60 is attached to the pressing head 40 so as to be displaceable in the first posture and the second posture by the mounting portion 70. Therefore, it can be used as a 2-way container that can be used by being displaced to the first posture and the second posture according to the usage mode. For example, in the first posture, the contents may be directly attached to the palm or the like to be pressed as described above, or the contents may be attached to an applicator such as a paper towel such as a hand wrap container. .. Further, in the second posture, 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.

Further, in the present embodiment, when the discharge cover 60 is displaced to the second posture, the flat plate-shaped back surface portion 73 is arranged above the mouth portion 11, and the back surface portion 73 is pressed in the second position. Since it functions as a unit, the pressing operation of the pressing head 40 is easy even in the second posture.

Further, in the present embodiment, as described above, the support portion 62 is composed of four plate-shaped members 62a, and two of them are attached to the side surface portions 72 of the attachment portion 70. Therefore, in the second posture, a wide opening can be secured downward in the axial direction. Therefore, when the pressing head 40 is pressed in the second posture, when the spraying range for spraying the contents from the discharge port 31 is widened, the center of the ring-shaped portion 61 is not obstructed by the support portion 62. The contents can be sprayed to the outside from the opening between the plate-shaped members 62a in addition to the opening of the portion.

Further, in the present embodiment, the guide groove hole 43c is provided in the upper head portion 43, and the discharge port portion 30 is moved along the guide groove hole 43c so that the direction in which the contents are discharged can be easily switched. .. At that time, in the present embodiment, the discharge port portion 30 can be moved along the guide groove hole 43c by a simple operation of tilting and rotating the discharge cover 60. Therefore, unlike the conventional 2-way specification discharge container, for example, it is not necessary to provide a plurality of discharge ports 31 and close the unused discharge ports 31 with a seal member, and the configuration can be simplified.

Further, in the present embodiment, the discharge port portion 30 is configured to include the rotary cylinder 33 and the discharge cylinder 32, and the rotary cylinder 33 is rotatably held by the rotary cylinder holding portion 44. Therefore, it is easy to rotate the discharge port portion 30 while connecting the stem 52 of the pump mechanism 50 and the discharge port portion 30, and the upper end of the stem 52 and the lower end of the discharge port portion 30. The distance between them can be reduced. In addition to this point, a tubular connecting member that directly connects the rotating cylinder 33 and the stem 52 is not used. When the rotary cylinder 33 and the stem 52 are directly connected by the connecting member, mechanical stress such as bending of the connecting member is applied when the rotary cylinder 33 is rotated, and the connecting member is deteriorated. It is also assumed. However, in the present embodiment, by adopting the above-mentioned configuration, it is not necessary to use a member susceptible to mechanical stress, so that the discharge pump 100a and the pump container 100 can be used satisfactorily for a long period of time. can.

The above embodiment is an example of the discharge pump and the pump container according to the present invention, and the discharge pump and the pump container according to the present invention are not limited to the above embodiment and do not deviate from the gist of the present invention. It can be changed as appropriate. For example, in the above embodiment, the ring-shaped portion 61 made of an annular 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, when the discharge cover 60 is attached to the discharge cover 60 in a predetermined direction, the ring-shaped portion 61 opens upward in the axial direction of the discharge port 31, and the opening is rectangular or polygonal. , An irregular shape or the like may be replaced with an opening frame formed in a frame shape of various shapes, and the opening frame may function as the first pressing operation unit. At this time, the opening frame does not need to have a similar shape between the opening shape and the outer shape. That is, the opening frame referred to in the present invention may have a different shape from the opening shape and the outer shape, and the specific shape of the opening frame is not limited.

Further, in the above embodiment, the opening frame is configured as a ring-shaped portion 61 composed of an annular ring ring which is a closed figure, but the opening frame according to the present invention does not have to have a closed figure shape, for example, FIG. In the second posture shown in the above, a C-shaped shape may be provided in which a notch is provided in the lower portion of the ring-shaped portion 61, or a notch may be provided in the upper and lower portions of the ring-shaped portion 61 in the second posture. Of course, even if the opening frame has another shape, such a notch may be provided.

Further, in the above embodiment, the discharge cover 60 is composed of four plate-shaped members 62a, and an opening is provided between the plate-shaped members 62a adjacent to each other, but the number of the plate-shaped members 62a is limited to four. It is not something that will be done. If the support portion 62 is composed of a plurality of plate-shaped members 62a and an opening is provided between the adjacent plate-shaped members 62a as in the above embodiment, the contents are suppressed from being stored in the discharge cover 60. can do. However, for example, the top wall surface 71, the support portion 62, and the ring-shaped portion 61 of the mounting portion 70 may be integrally formed into a cup shape or a dish shape. Further, at that time, a ring shape is provided by providing a plurality of openings in the support portion while being configured as a support portion that supports between the mounting portion 70 and the ring shape portion 61, such as providing a mesh shape or a large number of holes. The same effect as described above can be obtained by arranging the portion 61 upward in the axial direction with respect to the discharge port 31 and preventing the contents discharged from the discharge port 31 from being stored in the discharge cover 60. ..

Further, the configuration of the discharge port portion 30 and the specific configuration of the pump mechanism 50 and the like are not particularly limited, and conventionally known configurations can be appropriately adopted. Further, in the above embodiment, the discharge cover 60 may be configured to be easily attached to and detached from the pressing head 40 by the mounting portion 70. The discharge cover 60 can be cleaned at a desired timing by allowing the user to easily attach and detach the discharge cover 60 from the pressing head 40. Therefore, the discharge cover 60 as the operation pressing portion can be hygienically held.

Further, the pump container 100 and the discharge pump 100a are various resin materials used as container packaging materials (for example, polyethylene resin (PE) such as polypropylene resin (PP), low density polyethylene (LDPE) and high density polyethylene resin (HDPE)). In addition, polyethylene terephthalate resin (PET) or the like) can be appropriately adopted. Further, the discharge pump 100a and the pump container 100 may be made of a resin material or the like in which an antibacterial agent is kneaded, or the surface may be coated with an antibacterial coat or the like. Further, the container body 10 is not limited to the resin, but may be made of glass, metal, or the like.
