It is provided at the corresponding position.
- the highest portion of the high portion 51 and the thinnest portion of the thin portion 49 are located between a pair of radially extending lines connecting both ends of the through hole 53 in the longitudinal direction to the center of the partition wall 45. ..
- the center of the central region 54 that is, the center of the partition wall 45 is provided with a mounting hole 59 for mounting the valve body 43.
- the valve body 43 includes a plate-shaped portion 57 for closing the through hole 53 and a mounting protrusion 58 protruding from the plate-shaped portion 57.
- the plate-shaped portion 57 includes a first surface 57a facing the partition wall 45 and a second surface 57b facing the second space 47 on the opposite side of the first surface 57a.
- the plate-shaped portion 57 has a size that can be arranged on the second outer peripheral wall 72 that partitions the second space 47, and has a circular plate shape here. As shown in FIG. 8, there is a slight gap 57c (see FIG.
- This gap 57c is a gap through which milk flows.
- the first surface 57a has a flat surface shape
- the second surface 57b has an annular protrusion 60 (see FIG. 3) so as to connect positions corresponding to a plurality of through holes 53. I have.
- the annular protrusion 60 suppresses the deformation of the plate-shaped portion 57 by increasing the thickness of the plate-shaped portion 57.
- the first surface 57a is an opposite surface toward the partition wall 45.
- the first surface 57a is frosted, and the surface of the first surface 57a is formed with fine irregularities.
- the first surface 57a is prevented from sticking to the partition wall 45 by frosting.
- the center of the first surface 57a is provided with a mounting protrusion 58.
- the mounting projection 58 is provided with an annular bulging portion 58a at the tip thereof, and thus has a locking groove 58b at the base of the bulging portion 58a.
- the plate-shaped portion 57 is arranged in the second space 47 so as to be close to and separated from the partition wall 45.
- the valve body 43 is attached to the cap 42, in the second space 47, between the outer peripheral end of the plate-shaped portion 57 and the inner surface (inner peripheral surface) 73 of the second outer peripheral wall 72 that partitions the second space 47.
- the through hole 53 is formed rather than the position corresponding to the connecting portion 56. The corresponding position divides a wider space.
- the milking machine 1 in the decomposed state is assembled as follows. First, the valve member 41 is in a state where the cap 42 and the valve body 43 are separated from each other. To assemble the valve member 41, the valve body 43 is inserted with the mounting projection 58 facing the partition wall 45 with respect to the second space 47 in the cap 42 while looking at the mounting direction display unit 50. That is, it is possible to prevent the user from accidentally inserting the cap 42 into the first space 46. Then, by inserting the mounting projection 58 into the mounting hole 59, the peripheral edge of the mounting hole 59 in the partition wall 45 is locked in the locking groove 58b. As a result, the cap 42 of the valve member 41 is integrated with the valve body 43.
- the first space 46 of the cap 42 is fitted onto the lower end 26a of the temporary storage portion 26. Since the cap 42 is a molded product of an elastic synthetic resin material, it is in close contact with the lower end 26a. At this time, the user can easily confirm the mounting direction of the valve member 41 to the lower end 26a by checking the mounting direction display unit 50.
- the pulling plate 17 and the insertion member 30 are integrated, and the insertion portion 30a is inserted into the negative pressure generation path 27.
- the connection protrusion 32 is inserted into the insertion hole 14a of the diaphragm 14, and the diaphragm 14 is attached to the mounting end 24.
- the handle base 16 is attached to the main body 11.
- the connecting protrusion 32 is engaged with the lift portion 37 of the handle 15.
- the support shaft portion 36 of the handle base 16 is engaged with the bearing portion 39 of the handle 15.
- the bottle 12 is attached to the bottle attachment portion 21 of the main body 11, and the hood 13 is attached to the hood attachment portion 22.
- the milking device 1 when milking, the milking device 1 is held by the user, and the hood 13 is applied to the user's breast so as to close the milking port 13c. As a result, a substantially enclosed space is partitioned in the internal passage 23.
- the diaphragm 14 When the handle 15 is manually rotated in the direction of the arrow D1 in which the lever portion 38 is close to the side surface of the bottle 12, the diaphragm 14 is pulled up via the pull-up plate 17. At this time, by pulling up the diaphragm 14, the insertion portion 30a rises in the negative pressure generation path 27. Then, since the internal passage 23 is in a negative pressure state, the milked milk flows into the temporary storage unit 26 from the inflow passage 25. When the temporary storage unit 26 is in a negative pressure state, the valve member 41 closes the bottom of the temporary storage unit 26, so that the milk flowing from the inflow path 25 is stored in the temporary storage unit 26. That is, the valve member 41 can temporarily store milk in the internal passage 23 of the milking device 1 when the milking device 1 is in a negative pressure state.
- valve body 43 when the handle 15 is not rotated in the direction of arrow D1, the internal passage 23 is in a normal pressure state, and as shown in FIG. 8, the plate-shaped portion of the valve member 41 57 is arranged in the second space 47 so as to be close to and separated from the partition wall 45. That is, a gap 61 is formed between the partition wall 45 and the first surface 57a.
- the partition wall 45 and the plate-shaped portion 57 are both molded products of an elastic synthetic resin material, they are in close contact with each other when the internal passage 23 is in a negative pressure state. Therefore, the milk stored in the temporary storage unit 26 is less likely to leak from the through hole 53.
- the handle 15 rotates in the direction of arrow D2 due to the action of elastically returning the diaphragm 14, and the internal passage 23 returns to normal pressure.
- the valve body 43 of the valve member 41 loosens with respect to the partition wall 45, so that the valve body 43 is arranged so as to be close to and separated from the partition wall 45 again.
- the milk stored in the temporary storage portion 26 flows down through the through hole 53 and is received by the plate-shaped portion 57, and the partition wall 45 and the first surface 57a of the plate-shaped portion 57 are received.
- the valve member 41 is configured to allow the milk stored in the internal passage 23 to flow out when the milking device 1 is in a normal pressure state.
- the internal passage 23 is configured to connect the milking port 13c partitioned by the hood 13 to the bottle 12.
- the valve member 41 makes it possible to temporarily store milk from the hood 13 in the internal passage 23 when the milking device 1 is in a negative pressure state due to the negative pressure generation mechanism.
- the valve member 41 is further configured to allow the milk stored in the internal passage 23 to flow out to the bottle 12 when the milking device 1 is in a normal pressure state.
- the position of the thin portion 49 is higher than the position of the thick portion 48.
- a wider space is constructed by the person. That is, the gap 57c between the outer peripheral end of the plate-shaped portion 57 and the inner surface 73 of the second outer peripheral wall 72 that partitions the second space 47 corresponds to the through hole 53 rather than the position corresponding to the connecting portion 56. The position constitutes a wider space. Therefore, a part of the milk flowing down from the through hole 53 and received by the plate-shaped portion 57 smoothly flows in the direction of the thin portion 49 at the position of the through hole 53.
- the rest of the milk flows in the direction of the thick portion 48.
- the milk flowing through the thin portion 49 flows toward the tip portion (lower end) of the high portion 51.
- the milk flowing through the thick portion 48 flows from the thick portion 48 to the thin portion 49.
- most of the milk is dropped onto the bottle 12 from the tip (lower end) of the high portion 51 where the thin portion 49 is located.
- a part of the milk is directly dropped onto the bottle 12 from the outer peripheral end of the plate-shaped portion 57.
- Milking is performed by repeatedly reciprocating the handle 15, and the insertion portion 30a also reciprocates in the negative pressure generation path 27 in accordance with the reciprocating movement of the handle 15. As a result, the normal pressure state and the negative pressure state are repeatedly formed in the internal passage 23. Therefore, the milk is sequentially stored in the temporary storage unit 26, and the milk stored in the temporary storage unit 26 is dropped into the bottle 12.
- the milking machine 1 is disassembled as shown in FIG. 2 for cleaning. That is, the bottle 12, the hood 13, the handle 15, the handle base 16, the diaphragm 14, and the pull-up plate 17 to which the insertion portion 30a is attached are removed from the main body 11. Then, the valve member 41 is also removed from the main body 11. The valve body 43 is separated from the cap 42 of the valve member 41.
- the milking machine 1 can be easily assembled and disassembled and easily cleaned with a finger or a brush.
- each member of the valve member 41 can be easily cleaned by using a finger or a brush.
- the cap 42 does not have a small recess such as a small through hole or a deep hole, the first space 46, the second space 47, and the through hole 53 can be easily cleaned. Since the valve body 43 also has no fine dents, the valve body 43 can also be easily cleaned. After cleaning, the milking machine 1 is assembled as described above.
- the valve member 41 can be easily cleaned by removing the valve body 43 from the cap 42 of the valve member 41. Therefore, the milking machine 1 can be kept clean.
- a part of the milk is transmitted from the outer peripheral end of the valve body 43 to the thick portion 48 and the thin portion 49, and flows from the tip of the outer peripheral wall 44 to the bottle 12.
- a part of the milk is rectified and flows from the tip end (lower end) of the second outer peripheral wall 72 that partitions the second space 47 to the bottle 12. Therefore, for example, the dripping sound can be reduced as compared with the case where the milk is scattered and dropped into the bottle.
- a lower portion 52 having a second height H2 is provided in a portion of the outer peripheral wall 44 that divides the second space 47. Therefore, for example, by providing the lower portion 52 of the second height H2, the outer peripheral wall 44 has elasticity, as compared with the case where the outer peripheral wall is formed on the high portion 51 having a uniform height so as to be aligned with the first height H1. The amount of synthetic resin material used can be reduced.
- the portion of the thin portion 49 configured at the position corresponding to the through hole 53 has the meat configured at the position corresponding to the connecting portion 56.
- the thick portion 48 There is a wider space than the thick portion 48. Therefore, a part of the milk flowing out from the through hole 53 tends to flow in the thin portion 49. Then, a part of the milk is transmitted from the outer peripheral end of the valve body 43 to the thick portion 48 and the thin portion 49, and most of the milk flows from the tip end portion of the outer peripheral wall 44 to the bottle 12.
- the valve body 43 comes into close contact with the partition wall 45, so that the through hole 53 can be firmly closed.
- the first surface 57a which is the surface facing the partition wall 45, is frosted so that sticking to the partition wall 45 can be suppressed.
- the above embodiment may be modified as follows. -On the first surface 57a of the plate-shaped portion 57, the frosting process suppresses the sticking of the first surface 57a to the partition wall 45.
- the frosting process does not necessarily have to be provided on the surface of the mounting projection 58.
- the frost processing may be provided at least at a position of the first surface 57a facing the connecting portion 56 of the partition wall 45.

- the valve body 43 is not limited to a synthetic resin material having the same elasticity as the cap 42.
- the cap 42 may be a molded product of a synthetic resin material having rigidity with respect to the valve body 43. This is because the valve body 43 only needs to be able to close the through hole 53.
- the number of through holes 53 may be one, two, or four or more. As an example, a large number of through holes 53 as a part of a perfect circle or a part of an elliptical shape may be provided in a scattered pattern around the mounting holes 59. Further, the shape of the through hole is not limited to the elongated hole having an arc shape. As an example, the through hole 53 may be a long hole having a linear shape extending in the radial direction.

- the height of the second outer peripheral wall 72 from the partition wall 45 may be uniformly aligned with the first height H1, which is the height of the high portion 51. As a result, the dropping sound can be reduced.
- the height of the second outer peripheral wall 72 from the partition wall 45 may be aligned with the second height H2 of the lower portion 52. As a result, the amount of synthetic resin material used can be reduced.
- the outer peripheral wall 44 does not have the thick portion 48 and the thin portion 49, and may be configured to have the same thickness. For example, if the strength of the outer peripheral wall 44 can be secured, the thickness of the outer peripheral wall 44 may be made uniform by the second thickness T2 of the thin portion 49. As a result, the amount of synthetic resin material used can be reduced. On the contrary, the thickness of the outer peripheral wall 44 may be made uniform by the first thickness T1 of the wall thickness portion 48.

Abstract
Description
図1に示すように、搾乳器1は、使用者が片手で操作可能な大きさを有した手動の搾乳器である。搾乳器1は、本体11と、ボトル12と、フード13と、ダイヤフラム14(図2参照)と、ハンドル15と、ハンドルベース16と、引き上げプレート17とを備えている。
分解状態にある搾乳器1は、次のように組み立てられる。
まず、弁部材41は、キャップ42と弁体43とが互いに分離した状態にある。弁部材41を組み立てるには、取付方向表示部50を見ながら、キャップ42における第2空間47に対して、取付突起58を仕切壁45に向けて、弁体43が挿入される。すなわち、ユーザが誤って、第1空間46にキャップ42を挿入してしまうことを防ぐことができる。そして、取付突起58は取付孔59に挿入されることで、係止溝58bに、仕切壁45のうちの取付孔59の周縁が係止される。これにより、弁部材41のキャップ42は、弁体43と一体化される。この後、キャップ42の第1空間46は、一時貯留部26の下端26aに外嵌される。キャップ42は、弾性を有する合成樹脂材料の成形品であるので、下端26aに対して密着される。この際、ユーザは、取付方向表示部50を確認することで、下端26aへの弁部材41の取付方向を容易に確認できる。
(1)弁部材41のキャップ42から弁体43を取り外すことで、弁部材41を容易に洗浄できる。したがって、搾乳器1を清潔に維持できる。
(3)貫通孔53から第2空間47へ流出した乳汁は、弁部材41の板状部57で受けられてから外周壁44の方向に流れる。貫通孔53に続く外周壁44の内側の空間は、肉厚部48の部分より肉薄部49の部分の方が広い。したがって、貫通孔53から流出して板状部57で受けられた乳汁は、肉薄部49の部分において外周壁44へ流れ易くなる。乳汁の一部は、弁体43の外周端から、肉厚部48および肉薄部49へ伝わり、外周壁44の先端からボトル12へ流れる。このように、乳汁の一部は、整流されて、第2空間47を区画する第2外周壁72の先端(下端)からボトル12へ流れる。よって、例えば乳汁が飛散してボトルに滴下する場合と比べて、滴下音を小さくできる。
(8)仕切壁45との対向面である第1面57aは、フロスト加工が施されることで、仕切壁45に対する貼り付きを抑えることができる。
・板状部57の第1面57aにおいて、フロスト加工は、仕切壁45に対する第1面57aの貼り付きを抑える。フロスト加工は、取付突起58の表面には必ずしも設けられている必要はない。フロスト加工は、第1面57aのうち、少なくとも仕切壁45の連結部56に対向する位置に設けられていればよい。
・第2空間47を区画する第2外周壁72において、高部51と低部52との両方を備えていなくてもよい。一例として、仕切壁45からの第2外周壁72の高さを、高部51の高さである第1高さH1に均一に揃えてもよい。これにより、滴下音を小さくできる。これとは逆に、仕切壁45からの第2外周壁72の高さを、低部52の第2高さH2に揃えてもよい。これにより、使用する合成樹脂材料を少なくできる。第2空間47を区画する第2外周壁72の高さを揃えることで、外周壁44の構造を簡素化できる。
本明細書における記述「A及びBの少なくとも一つ」は、「Aのみ」または「Bのみ」または「AとBの両方」を意味するものとして理解されたい。
