[0001]

TECHNICAL FIELD The present invention relates to a contact lens case and a contact lens processing case using the same, and more particularly, by enclosing the contact lens together with a predetermined processing solution, cleaning, storage, disinfection, etc. of the lens. A case for contact lenses suitable for processing
The present invention relates to a contact lens processing case configured to include such a case and capable of performing an extremely effective cleaning operation.

[0002]

BACKGROUND ART Generally, when a contact lens is taken out of the eye, it is necessary to perform a series of cleaning, rinsing, and preservation processes, and for soft contact lenses, it is also necessary to periodically perform boiling disinfection. . That is, lipids, proteins, organic substances such as sugars and inorganic substances such as calcium and magnesium contained in the tears adhere to the contact lens during use, and thus must be removed by washing.

And, as one of the methods, Jitsuko Sho 5
As disclosed in Japanese Patent Publication No. 9-24015 and Japanese Utility Model Laid-Open No. 63-96533, a method of shaking a contact lens in a container using a dedicated cleaning container in which a cleaning liquid can be enclosed together with the contact lens is used. is there.

By the way, such a washing container for shaking washing is usually made extremely compact so that it can be easily grasped with one hand and shaken. Therefore, a smaller washing container fixed in a small washing container is used. The contact lens must be stored inside the contact lens holder, or the contact lens must be taken out from it.
There is an inherent problem that it is troublesome to handle.

On the other hand, in such a cleaning container, in order to obtain a high cleaning effect, it is necessary that the cleaning liquid, which is made to flow by the shaking operation, effectively contacts the surface of the contact lens. Therefore, in order to prevent the contact lens from flowing together with the flowing liquid, a contact lens holder is usually provided and the contact lens is housed inside the holder.

However, conventionally, the contact lens housed in the holder has not been effectively cleaned because the orientation of the lens at the time of cleaning has not been taken into consideration. For the most effective cleaning, the contact lens should be held in a vertical state (the axial direction of the lens and the flowing direction of the liquid are parallel) with respect to the flowing direction of the cleaning liquid. It is desirable.

In short, these problems have not been sufficiently dealt with in the conventional cleaning container, which may make the operator difficult to handle and may cause insufficient cleaning.

That is, in the cleaning container disclosed in Japanese Utility Model Publication No. 59-24015, by removing the cover of the container, the lens holder fixed inside the cover is also taken out of the container at the same time. However, in order to store the contact lens in the lens holder, it is necessary to insert the contact lens into the inside through a narrow cut opening (opening) of the holder. Further, in this container, the contact lens is fixedly arranged in a state parallel to the flow direction of the cleaning liquid (a state in which the axial direction of the lens and the flow direction of the liquid are vertical), so that the cleaning liquid does not hit well and No clean can be done.

Also, in the cleaning container disclosed in Japanese Utility Model Laid-Open No. 63-96533, the contact lens is fitted in the narrow groove of the lens holder having a saucer shape, so that it is inconvenient to take the lens in and out. is there. Moreover, this lens holder is more troublesome to handle because the contact lens needs to be taken out from the container one by one in addition to the removal of the lid. Furthermore,
Since the lens holder is in a state in which it can be slightly moved and rotated in the vertical direction in the cleaning container, the cleaning liquid does not hit the lens surface poorly and the rotation is uneven. However, there is a problem that the cleaning effect cannot be expected, and the container itself is complicated, so that the container is easily damaged.

In addition, each of the cleaning containers mentioned here is
It is for hard contact lenses, and cannot be actually used for soft contact lenses.

[0011]

The present invention has been made in view of such circumstances, and a problem to be solved is to clean, store, and disinfect by enclosing a predetermined treatment liquid together with a contact lens. In a case for a contact lens that can be subjected to such treatments, the lens can be easily taken in and out, and at the time of cleaning, the direction of the lens can be maintained in a state perpendicular to the flowing direction of the liquid to improve the contact of the cleaning liquid with the lens surface. However, effective cleaning can be performed. In addition, the flow of the liquid generated in the case at the time of cleaning can be effectively enhanced so that a more excellent cleaning effect can be obtained.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to clarify the present invention more specifically, a typical embodiment of the present invention will be described in detail below with reference to the drawings.

First, FIG. 1 shows an entire contact lens case 10 according to the present invention. Here, 12 is a bottomed cylindrical container body, and a male screw 14 is formed on the outer circumference of the opening. Also, 16
Is a cap member that closes the opening of the container body 12, and a female screw 18 provided on the inner circumference of the opening,
The contact lens case 10 is screwed onto the male screw 14 of the container body 12 and attached in a liquid-tight state.
It is designed to form a sealed space inside. Although the container body 12 and the cap member 16 are attached by screwing here, any attachment method other than screwing may be used as long as the liquid-tight state can be maintained.

The cap member 1 is placed in the closed space formed by the container body 12 and the cap member 16.
The support member 20 fixed to the inside of the bottom of 6 and the lens holder 30 supported by the support member 20 are positioned. More specifically, the support member 20 is a plate material having a substantially U-shape, and is integrally fixed to the cap member 16 at a U-shaped back portion 22 having a length slightly shorter than the inner diameter of the cap member 16. -ing On the other hand, a pair of arm portions 24 extending vertically from both ends of the back portion 22,
Through holes 26, 26 are provided at the tip of 24. Then, in the through holes 26, 26, the mounting shafts 28, 28
The lens holder 30 capable of accommodating a pair of left and right contact lenses in the inserted state is rotatably supported by the support member 20.

By the way, the lens holder 30 is
As shown in FIG. 2, contact lenses are internally provided on both sides of a rectangular plate-shaped turntable 32 in which the mounting shafts 28, 28 are integrally formed at central portions of a pair of opposing side surfaces thereof. Rectangular plate-shaped opening / closing pieces 36, 36 having a dish-shaped portion 34 that forms a spherical recess that can be stored are connected by a hinge portion 38, and are formed. That is, the opening / closing piece 36,
The hinge unit 38 can be opened and closed with respect to the turntable 32. The opening / closing piece 36 is
A claw 40 provided at a portion facing the formation portion of the hinge portion 38 is retained in a closed state by being locked in a notch 42 provided in the rotary disc 32.

Further, the size of the spherical recess of the dish-shaped portion 34 of the opening / closing piece 36 is such that the diameter is slightly larger than the diameter of the contact lens housed and the depth is smaller than the height of the contact lens. The depth of the contact lens accommodated in the spherical recess of the dish-shaped portion 34 can be maintained in a state of being aligned with the orientation of the lens holder 30.

Further, a large number of through holes 44 are provided in a portion of the plate-like portion 34 of the opening / closing piece 36 and a portion of the rotating plate 32 corresponding to the dish-like portion 34. The liquid can freely come into contact with the contact lens housed in the spherical concave portion. The size, shape, number, etc. of the through holes 44 are not particularly limited,
A hole, a mesh, or the like, through which a predetermined processing liquid such as a cleaning liquid can pass and which prevents the contact lens from passing through, is appropriately provided. That is, in this embodiment, the spherical recesses of the dish-shaped portions 34, 34 of the opening / closing pieces 36, 36 are configured as a lens holding chamber capable of housing the contact lens.

The container body 12, the cap member 16, the support member 20, the lens holder 30 and the like are made of a material which is not affected by a liquid such as a cleaning liquid and does not affect the liquid. However, synthetic resin is preferable, but particularly when formed of an antibacterial resin material containing antibacterial zeolite or the like, the growth of bacteria or mold mixed in the contact lens case 10 is effectively prevented. You can

Here, on the side surface of the turntable 32, locking pieces 46, 46 projecting at a predetermined height are integrally formed at a position separated by a predetermined dimension from the position where the mounting shafts 28, 28 are formed. The end portion of the arm portion 24 of the support member 20 corresponding to the position where the locking piece 46 is formed has one of the corners, as shown in FIG. The circular arc portion 48 has a radius slightly larger than the distance between the mounting shaft 28 of the board 32 and the locking piece 46,
The other corner is an extension 50 extending in the side direction. And thereby, the locking piece 46
Only when the operator pushes and turns the turntable 32, the operator can pass through the circular arc portion 48 based on the elastic deformation, but cannot pass through the extension portion 50. Is there.

In other words, the lens holder 30 can rotate within a range of substantially 90 ° due to the presence of the locking piece 46, and moreover, unless the operator operates it, the axis of the container body 12 can be rotated. It is locked so as to be positioned in a direction perpendicular to the direction (see FIG. 3) or in a direction parallel to the direction (see FIG. 4), and either one of the locked states is held.
Further, the orientation of the contact lens housed in the lens holding chamber of the lens holder 30 is also determined by the lens holder 3
Corresponding to each of the two locking positions 0, the container body 1
The two can be positioned in parallel or perpendicular to the axial direction.

As is apparent from this, in the present embodiment, the locking mechanism is configured by including the locking piece 46 of the rotating plate 32, the arcuate portion 48 and the extending portion 50 of the supporting member 20. Is there.

Such a contact lens case 10
In order to clean the contact lens by using the lens holder, first, as shown in FIG.
It is rotated so as to be parallel to the axial direction of (1) and is fixed at that position by the locking mechanism (46, 48, 50). By doing so, the support member 20 and the cap member 16 do not interfere with the operation of the opening / closing pieces 36, 36, and the opening / closing pieces 36, 36 can be widely opened, so that the contact lens 51 can be easily taken in and out. It will be.

After the contact lens 51 is housed and the opening / closing piece 36 is closed, the turntable 32 is turned to bring the lens holder 30 to the locking position perpendicular to the axial direction of the container body 12. Fix (see Figure 3). In the present embodiment, even if this turning operation is forgotten, the cap member 16 cannot be screwed into the container body 12 when the lens holder 30 remains parallel to the axial direction of the container body 12. In addition, the lens holder 30 contacts the bottom of the container body 12 so that an erroneous operation can be avoided.

Next, the cap member 16 is screwed onto the container body 12 into which a predetermined amount of cleaning liquid has been injected in advance, and the lens holder 30 is housed in the hermetically sealed space so that they are liquid-tightly coupled. Of. The amount of the cleaning liquid sealed in the contact lens case 10 is preferably several ml to a little less than the amount for filling the case 10 in order to accelerate the flow of the liquid. Particularly preferably, about half of the case 10 is sealed.

Then, the contact lens 51 and the contact lens case 10 in which the cleaning liquid is sealed are grasped with one hand and are shaken or inverted in the axial direction, so that the cleaning liquid is stored in the container body 12. The contact lens 51 is washed with the flowing liquid by violently flowing in the axial direction. Here, since the lens holder 30 is locked in a state perpendicular to the axial direction of the container body 12, the contact lens 5 housed inside is held.
The direction 1 is also in a state perpendicular to the axial direction of the container body 12, that is, the flowing direction of the cleaning liquid. Therefore, the cleaning liquid that is made to flow hits the surface of the contact lens 51 very effectively, and an excellent cleaning effect is obtained.

Next, when the washing is completed, the washing liquid in the inside is discharged, the rinsing liquid is refilled, and the contact lens case 10 is shaken to perform rinsing. Further, when the rinsing is completed, the contact lens 51 is stored by newly refilling the storage solution in the contact lens case 10.

When the contact lens 51 is taken out from the lens holder 30 again, the lens holder 30 is rotated to the position shown in FIG. It is parallel to.

Further, even when the soft contact lens is sterilized by boiling, in the contact lens case 10 of this embodiment, the lens holder 30 is used as the support member 2.
Since it is removable from 0, the contact lens 51 is stored in the lens holder 30,
It can be transferred to a boiling sterilizer for disinfection operations.

As described above, by using the contact lens case 10 of the present embodiment, a series of operations such as cleaning, rinsing, and storage of the contact lens 51, and further boiling softening disinfection operation of the soft contact lens can be easily performed. You can do it. Moreover, since it is possible to secure a large opening / closing amount of the openable / closable lens holder 30, handleability when the contact lens 51 is taken in and out is good, and the contact lens case 10 itself has a simple structure. It is less likely to be damaged, and since the cleaning liquid can be made to hit the contact lens 51 from the vertical direction during cleaning, the cleaning effect can be effectively enhanced.
The contact lens case 10 of the present embodiment can be applied to both hard contact lenses and soft contact lenses.

Although an example of the contact lens case according to the present invention has been described in detail above, one embodiment of a processing case in which such a contact lens case is used to further enhance the cleaning effect will be described below. An example will be described.

FIG. 5 shows the entire contact lens processing case 52 according to the present invention. There
Reference numeral 54 denotes an outer cylinder having a long cylindrical shape, which is composed of a bottomed cylindrical main body 56 and a lid 58 screwed into an opening of the main body 56, and has a space inside. ing. The outer cylinder has an outer diameter slightly smaller than the inner diameter of the outer cylinder 54 and has a length of about 1/3 of the outer cylinder 54, which is an inner cylinder as a contact lens storage container. 6
0 is accommodated so as to be slidable in the axial direction of the outer cylinder 54. The barrel body 56, the lid 58, and the container body 12 of the inner cylinder 60 are all made of transparent synthetic resin, and the cleaning state of the contact lens housed in the inner cylinder 60 is observed from the outside. Is ready to go.

Further, here, a cylinder body 56 of the outer cylinder 54 is provided.
The lid 58 and the lid 58 are attached by screwing,
Any attachment method may be adopted as long as it does not come off even if the inner cylinder 60 strikes, and a one-touch fitting method or the like can be adopted.

The inner cylinder 60 is slidable in the axial direction in the outer cylinder 54 in a state where the contact lens to be cleaned and a predetermined amount of cleaning liquid are enclosed therein. The contact lens is cleaned based on the flow of the liquid to be filled, but the structure is exactly the same as that of the contact lens case 10 described above. That is, the lens holder 3 includes the container body 12, the cap member 16, the support member 20, the lens holder 30, and the locking mechanism (46, 48, 50).
0 is rotatable with respect to the support member 20, and is locked so as to be positioned in a direction parallel or perpendicular to the axial direction of the container body 12 due to the existence of the locking mechanism (46, 48, 50). It is supposed to get.

Therefore, since the inner cylinder 60 having such a structure is adopted, in the contact lens processing case 52, by appropriately switching the locking position of the lens holder 30, the contact lens is favorably taken in and out. Because it is easy to handle, when cleaning,
The liquid can satisfactorily hit the contact lens, and the cleaning effect can be further enhanced.

The cleaning operation using the processing case 52 is performed by simply swinging the outer cylinder 54 in the axial direction or inverting the top and bottom while the inner cylinder 60 is housed. Often, this allows the inner tube 60 to be axially reciprocally slidable between the closed ends of the outer tube 54. As a result, compared to the actual operation amount (the swing width of the outer cylinder 54), the inner cylinder 6
A large movement width of 0 is ensured, and the inner cylinder 60 is impacted when the inner cylinder 60 hits both closed ends of the outer cylinder 54.
The flow of the cleaning liquid in the inside is remarkably increased, and thus the cleaning effect of the contact lens is effectively improved. Therefore, if such a processing case 52 is used, such as cosmetics,
Even if oily stains that are difficult to remove adhere to the contact lens, the stains can be removed well.

Further, another embodiment of the contact lens case according to the present invention and the outer cylinder forming the contact lens processing case including the contact lens case will be described with reference to FIGS. 6 to 16. Since the basic structure of those cases is the same as that of the above-mentioned embodiment, in the following description, the same structure as that of the above-mentioned embodiment is denoted by the same reference numeral and the description thereof is omitted.

First, in the contact lens case 70 shown in FIG. 6 and FIG. 7, annular convex portions 72, 7 are formed around the outer peripheral surface at the upper end portion and the lower end portion of the cylindrical wall portion of the container body 12.
2 is formed, whereby an outer cylinder 8 described later is formed.
When the cleaning operation is performed using 0, the sliding resistance with the outer cylinder 80 is advantageously reduced, and the case 70 is less likely to be scratched. Further, in this container body 12, since the peripheral portion of the bottom wall portion is formed in the raised bottom 74, the usage amount of the processing liquid such as the cleaning liquid can be advantageously saved and the container wall 12 is Since the water level line 76 is provided, the amount of liquid required for one treatment can be grasped very easily.

On the other hand, in the lens holder 30 housed in the container body 12 as described above, the open / close pieces 36 shown in FIG. 10 are provided on both sides of the turntable 32 shown in FIGS. 8 and 9, respectively. It is integrally connected by a flexible connecting plate member 90 and is configured to be openable and closable (see FIG. 6). Thus, the turntable 32 is integrally bonded with the two plate members 92, 92 having the convex portion 91 corresponding to the inner surface shape of the contact lens in the central portion, with their back surfaces facing each other. The convex portions 91 are projected on both sides of the rotary plate 32. Therefore, the turntable 32
The shape of the lens holding chamber formed between the plate-shaped portion 34 of the opening / closing piece 36 and the shape of the contact lens is substantially the same. Therefore, in the case where the contact lens is housed in the lens holding chamber of the lens holder 30 and the cleaning operation is performed, in addition to the cleaning effect by the flowing processing liquid hitting the surface of the contact lens, the contact lens is It is possible to obtain the effect of scrubbing by colliding with the dish-shaped portion 34 of the opening / closing piece 36 of 30 and the convex portion 91 of the rotating plate 32, and more efficient cleaning can be performed.

Further, as shown in FIG. 10, the notch 9 is formed in the opening / closing piece 36 of the lens holder 30 of this embodiment.
4 is provided so that the contact lens can be easily gripped with fingers or tweezers when the contact lens is taken in and out. Further, the claw 40 of the opening / closing piece 36 is provided with a symbol "R" or "L" so that it is possible to favorably prevent the lens from being mistaken for left and right when the contact lens is taken in and out. Furthermore, in such a lens holder 30, when the opening / closing piece 36 is closed with respect to the turntable 32, the notch 42 of the turntable 32 is provided so as not to accidentally pinch and crush the contact lens. By adjusting the engagement of the claw 40 of the opening / closing piece 36 with respect to the opening / closing piece 36, when the opening / closing piece 36 is closed, the turntable 3
A slight gap 95 is formed between the two (see FIG. 6).

Also in the contact lens case 70, the direction of the lens holder 30 is switched depending on the contact lens cleaning time and the contact lens removing time, respectively, and the contact position is shown in FIG. 6 or shown in FIG. A locking mechanism as described below is provided between the lens holder 30 and the support member 20 so that the locking mechanism can be positioned at the locking position.

That is, on the side of the lens holder 30, the locking pieces 46 are respectively provided on the pair of side surfaces of the turntable 32 facing each other at a predetermined distance from the mounting shafts 28, 28 formed in the substantially central portion. , 46 are formed.
On the other hand, on the support member 20 side, as shown in FIG. 11, a through hole 26 for fitting the mounting shaft 28 of the turntable 32 is enclosed on the inner side surface of the distal end portion of the arm portion 24, and Engagement recesses 96 for accommodating the engagement pieces 46 of the turntable 32 are formed at three locations on both sides and below. Further, between the lower locking recess 96 and the locking recesses 96, 96 on both sides, a step 98 having a height at which the locking piece 46 can jump due to elastic deformation of the arm 24 is provided. Each is formed.

Therefore, by passing over the stepped portion 98, the locking piece 46 of the turntable 32 can be moved between the three locking recesses 96, so that the lens holder 30 is moved to one position.
It can be rotated in the range of 80 °. Further, both of the opening / closing pieces 36 can be positioned below, and the opening portion of the opening / closing piece 36 is configured not to rotate to the cap member 16 side. Then, the position of the lens holder 30 is fixed by housing the locking piece 46 in one of the locking recesses 96. That is, here, the locking piece 46, the locking recess 9
6, the locking mechanism is configured to include the step portion 98.

Therefore, even if such a contact lens case 70 is used, by appropriately switching the locking position of the lens holder 30, good handleability can be obtained when the contact lens is taken in and out, and at the time of cleaning. Thus, the treatment liquid is satisfactorily applied to the contact lens, and the cleaning effect can be further enhanced.

Further, FIGS. 12 to 16 show different embodiments of the outer cylinder which houses the contact lens case 70 and constitutes the contact lens processing case. The outer cylinder 80 shown therein has a bottomed cylindrical shape 2
The two divided cylindrical bodies 82, 82 are integrally formed by fitting the divided cylindrical bodies 82, 82 to the fixing ring 84 with their openings abutting each other. A rail portion 86 is integrally formed on the inner peripheral surface of the outer cylinder 80 as a protrusion extending in the axial direction, and sliding resistance is advantageous when the contact lens case 70 is slid inside. In addition to being reduced, the surface of the contact lens case 70 is less likely to be scratched by sliding. Furthermore, the bottom surface of the two split cylinders 82, 82 of the outer cylinder 80 has a concave surface 87 on the outer surface.
The inner surface is formed as a convex surface 88, and at the concave surface 87,
While the outer cylinder 80 is easily gripped, the convex surface 88
Thus, the collision area between the outer cylinder 80 and the contact lens case 70 is reduced so that both are less likely to be scratched, and the collision noise is effectively reduced.

Here, as shown in FIGS. 14 and 15, on the fixing ring 84, locking claws 110 having a high protruding height are provided at four positions at equal intervals in the circumferential direction on one end side of the inner peripheral surface. Four locking claws 112 having a low protruding height are provided on the other end side of the inner peripheral surface at equal intervals in the circumferential direction. On the other hand, as shown in FIG.
Four locking grooves 114 into which the locking claws 110 or 112 are fitted are provided at equal intervals in the circumferential direction on the outer peripheral surface of the opening, and at the entrance of the locking groove 114,
A locking projection 116 is provided which is locked in the locking claw 110 or 112 fitted in the locking groove 114. Therefore, when the divided cylindrical bodies 82, 82 are assembled by rotating relative to the fixing ring 84, the locking claws 110, 112 exceed the locking projections 116 and enter the locking groove 114. By being inserted, the split cylindrical bodies 82, 82
And the fixing ring 84 are integrally fixed. Then, when detaching it, it is rotated in the opposite direction. However, since the heights of the locking claw 110 and the front locking claw 112 are different, the split that is assembled on the side of the locking claw 112 with a low protruding height. Barrel 82
Only the release ring 84-2
It is possible to favorably prevent the two divided cylindrical bodies 82, 82 from coming off at the same time.

Even when such an outer cylinder 80 is used,
It is possible to remarkably enhance the flow of the treatment liquid in the contact lens case 70 that can slide inside, and to effectively improve the cleaning effect of the contact lens.

By the way, when the contact lens processing case 52 having the structure shown in FIG. 5 is actually used to wash the contact lens to which the eye shadow (cosmetic) is attached, the stain can be completely removed. done. The dimensions and shape of the case used are as follows:
5 ml of a commercially available cleaning liquid (manufactured by Menicon Co., Ltd., Meniclean) was enclosed in the inner cylinder 60. Further, in the shaking operation, the outer cylinder 54 was held by hand, and was shaken in the axial direction about 20 times back and forth. (A) Outer cylinder-Outer diameter: 33 mm-Inner diameter: 29 mm-Thickness: 2 mm-Overall length: 104 mm (b) Inner cylinder-Outer diameter: 26 mm-Inner diameter: 22 mm-Thickness: 2 mm-Total length: 34 mm (C) Lens holder- Diameter of the spherical recess of the dish-shaped part: 16 mm-Depth of the spherical recess of the dish-shaped part: 5 mm-Thickness of the turntable and opening / closing piece: 1 mm-5 mm from the lower surface of the holder to the lower wall of the inner cylinder, of the holder It was supported at a position where the distance from the upper surface to the upper wall of the inner cylinder was 10 mm.

Although the typical embodiments of the contact lens case and the contact lens processing case according to the present invention have been described in detail above, the present invention is subject to any restrictions due to the description of such embodiments. Is not
Needless to say. Further, it should be understood that various changes, modifications and improvements can be added to the present invention based on the knowledge of those skilled in the art without departing from the spirit of the present invention. For example, the number of lens holding chambers formed is not limited to two, but may be one or three or more. Further, the locking mechanism is not limited to the illustrated one.

[0051]

As is apparent from the above description, in the case for a contact lens according to the present invention, the orientation of the contact lens housed in the holder can be changed by switching the locking position of the contact lens holder. Since it can be positioned in a state parallel or perpendicular to the axial direction of the container body, when the lens is taken in and out, the holder is rotated so that the operation is easy, so that the contact lens case can be handled easily. On the other hand, while cleaning, the holder is rotated so that the liquid to be flowed can effectively collide with the lens so that the lens is positioned in the direction perpendicular to the axial direction of the container body. At the very least, the cleaning effect can be effectively improved.

Further, in the contact lens processing case according to the present invention, since the contact lens case is used as the inner cylinder, the above-described effect is obtained, and the inner cylinder is axially moved in the outer cylinder. It is designed to be slidable back and forth, and the impact when the inner cylinder hits both closed ends of the outer cylinder causes a significantly large liquid flow compared to the actual amount of shaking operation, which is extremely effective. It is possible to perform various cleaning.
