Description

Contact lens package

The present invention relates to a contact lens package that contains a contact lens together with a storage solution, and more particularly to a contact lens package that is suitably used when distributing a soft contact lens to the market.

Contact lenses are stored in contact lens packages in a sealed state after being manufactured by a lens manufacturer, distributed to the market, and provided to users from a dealer.

By the way, a hydrous soft contact lens is provided in a contact lens package together with a storage solution. Such contact lens packages are conventionally formed on a container body made of a hard resin as described in JP-A-7-322911 (Patent Document 1) and US Pat. No. 4,691,820 (Patent Document 2). A blister package in which a storage solution and a contact lens are accommodated in the hollow and sealed with a cover film is employed.

However, the blister package having such a conventional structure must be formed with a sufficient depth to accommodate the contact lens, and it is difficult to make it compact. For this reason, for example, when a large number of contact lenses are stocked or when a plurality of contact lenses are carried around, it is bulky, and it is often inconvenient to handle.

Japanese Unexamined Patent Publication No. 7-322911 US Pat. No. 4,691,820

The present invention has been made against the background of the above-mentioned circumstances, and a solution to that problem is to provide a contact lens package having a novel structure that can accommodate a contact lens together with a storage solution in a more compact manner. It is in.

A first aspect of the present invention is a contact lens package in which a contact lens is housed in a package exterior body together with a preservation solution, and the first plate portion and the second plate portion are connected to each other so as to be bent at the connecting portion. A contact lens in which a lens clip is accommodated in the package exterior body and is pressed and deformed in the lens axial direction with the contact lens sandwiched between the first plate portion and the second plate portion that are overlapped with each other. In the package.

In the contact lens package of this aspect, since the contact lens is pressed and deformed in the axial direction (optical axis direction) by the lens clip and accommodated in a compressed state, the contact lens package can be made more compact than a blister package having a conventional structure. .

Moreover, since the contact lens is held by being sandwiched between the lens clips in a state of being accommodated in the package, the contact lens is stably maintained in a predetermined shape in the pressed deformation state. Therefore, even when an external force is exerted in the accommodated state, the contact lens is prevented from being repeatedly deformed such as bending and expansion and contraction, and the compressed state of the contact lens in the package is stably secured. Further, since the compression shape of the contact lens can be defined and maintained by the lens clip, it is possible to prevent the occurrence of large local deformation or undesirable distortion due to the action of external force or the like.

In particular, since the lens clip has an integrated structure in which the first plate portion and the second plate portion are connected by the connecting portion, the first plate portion and the second plate portion that are overlapped with each other. The mutual misalignment can be prevented by the connecting portion. Therefore, the contact lens sandwiched between the first plate portion and the second plate portion is not subjected to external force due to the displacement of the plate portion, and the contact lens is more stable between the two plate portions. Can be positioned and held.

Preferably, in this aspect, the size of the accommodation region in the package is an equilibrium state in the storage solution of the contact lens in the overlapping direction of the first plate portion and the second plate portion in the lens clip. It is made smaller than the height dimension in the optical axis direction (floating state where no external force is exerted). Thereby, the thickness dimension of the contact lens package itself can be reduced.

According to a second aspect of the present invention, in the contact lens package according to the first aspect, the first sheet covers the lens clip from both sides in the overlapping direction of the first plate portion and the second plate portion. And the second sheet are sealed at the outer peripheral portion of the lens clip to constitute the package exterior body.

In the contact lens package of this aspect, the structure of the package exterior body can be simplified and the manufacture thereof can be facilitated. In particular, since the package exterior body is configured with a bag-like structure in which the first sheet and the second sheet are sealed at the outer peripheral portion, the entire package can be made thinner and more compact. And by thinning the whole package, you can easily carry it in a pass case when carrying it, etc. Also, when stocking many, you can stack many in a compact case such as a box It becomes possible to store efficiently.

According to a third aspect of the present invention, in the contact lens package according to the second aspect, the first plate portion and the second plate portion are compared to the first sheet and the second sheet. And has great rigidity.

In the contact lens package of this aspect, the member strength required for protecting and holding the contact lens in the lens clip can be advantageously ensured, and the package outer body is made soft so that it can be easily handled at the time of opening. It becomes possible to do. In short, the protection of the contact lens and the improvement of the unpacking usability can be achieved in a highly compatible manner.

According to a fourth aspect of the present invention, in the contact lens package according to the second or third aspect, the atmospheric pressure acting on each outer surface of the first sheet and the second sheet causes the lens clip to A holding force in an overlapping state is exerted on the first plate portion and the second plate portion.

In the contact lens package of this aspect, a special locking structure is used to maintain the first and second plate portions of the lens clip in an overlapped state (contact lens holding state), or It is not necessary to form the first and second sheets with a hard material, and the lens clip and the package outer package can be simplified.

A fifth aspect of the present invention is the contact lens package according to any one of the first to third aspects, wherein in the lens clip, the first plate portion and the second plate portion are overlapped. Locking means for maintaining the state is provided.

In the contact lens package of this aspect, the lens clip can be reliably locked in the contact lens holding state, and more stable lens holding and lens protection by the lens clip can be realized. Note that the locking means of this aspect includes, for example, a locking concave portion and a locking convex portion that lock the first plate portion and the second plate portion in an overlapping state, or a locking claw and a locked portion. The first plate portion and the second plate portion can be formed integrally with each corresponding position, or can be realized separately from the lens clip and overlapped with the first plate portion and the second plate portion. It is also possible to employ a fitting ring, a locking clip, or the like that is externally fitted to the second plate portion.

A sixth aspect of the present invention is the contact lens package according to any one of the first to fifth aspects, wherein in the lens clip, the first plate portion, the second plate portion, and the connecting portion. Are integrally formed.

In the contact lens package of this aspect, it is possible to reduce the number of parts in the lens clip and thus the entire package, facilitate the structure and manufacturing, and improve the reliability associated therewith. Note that the connecting portion can be made bendable by reducing the strength by partially reducing the cross-sectional area of the component by, for example, making it thinner than the plate portion or by reducing the width dimension. Thereby, the target lens clip can be easily realized by an integrally molded product made of a synthetic resin material.

In the contact lens package according to the first aspect or the like, the first plate portion and the second plate portion formed separately can be connected and integrated later with a connecting portion made of tape or other parts. It is. As a result, for example, the first and second plate portions and the connecting portion can be made of different materials, and the first and second plate portions use a hard material to hold and protect the contact lens. On the other hand, it is also possible to improve the opening / closing operation of the first and second plate portions using a soft material at the connecting portion.

A seventh aspect of the present invention is the contact lens package according to any one of the first to sixth aspects, in the overlapping surface of at least one of the first plate part and the second plate part, A positioning engagement portion for engaging and positioning with the contact lens is provided.

In the contact lens package according to this aspect, the contact lens can be easily positioned in the manufacturing process in which the contact lens is held between the lens clips. In addition, since the contact lens can be held more stably at a predetermined position even in the accommodated state where the contact lens is held between the lens clips, unstable distortion or deformation due to the positional deviation of the contact lens is prevented. It can be prevented more effectively, and the use of the contact lens at a predetermined position even when opened is facilitated by the user.

Note that the positioning engagement portion in this aspect covers, for example, an annular recess groove into which the lens edge portion is fitted, a recess having an appropriate shape such as a circle in which the entire lens is fitted, or a concave surface of the lens. By providing a convex part or the like that fits on the overlapping surface of the first plate part or the second plate part, it can be suitably realized.

According to an eighth aspect of the present invention, in the contact lens package according to any one of the first to seventh aspects, the contact lens is sandwiched between at least one of the first plate portion and the second plate portion. A through window that allows the contact lens to be visually recognized from the outside is formed at the site.

In the contact lens package according to this aspect, it is possible to visually check the presence or absence of the contact lens and to check the degree of deformation of the contact lens while the contact lens is sandwiched between the lens clips. Thereby, for example, in the manufacturing process of the contact lens package, it is possible to prevent the occurrence of defective products by checking the presence or absence of the contact lens when inserting the lens clip into the package exterior body.

In particular, by making the package outer body transparent at least in the area corresponding to the through window of the lens clip, the contact lens package can be checked for the presence or state of the contact lens from the outside of the package outer body at the time of shipment. It is also possible to check the presence or state of contact lenses before use.

In this aspect, a plurality of through windows may be formed, or the through window may be configured by forming a mesh structure in a region where the contact lens is sandwiched in the lens clip. Further, in the case of forming the through windows in both the first plate portion and the second plate portion, respectively, by making the formation regions different from each other, while ensuring the holding power to the contact lens, A wide area can be visually confirmed through both windows.

According to a ninth aspect of the present invention, there is provided the contact lens package according to the eighth aspect, wherein the through window is formed in a circular shape at a central portion in a region sandwiching the contact lens.

In the contact lens package of this aspect, for example, the amount of pressing deformation to the optical part provided in the central part of the contact lens can be suppressed to be smaller than that in the peripheral part by providing the through window. As a result, it is possible to reduce or avoid the risk of a change in optical characteristics accompanying the pressing deformation of the contact lens.

According to a tenth aspect of the present invention, there is provided the contact lens package according to any one of the first to ninth aspects, wherein a portion of the first plate portion and the second plate portion sandwiches the contact lens. Provided with a knob that extends to the outer periphery and overlaps each other so that the first plate and the second plate can be pinched with fingers while the contact lens is sandwiched between them. It is what has been.

In the contact lens package of this aspect, when the user uses the contact lens, after opening the package exterior body, the handle is picked with the fingertips of the hand, and only the lens clip is held with the contact lens held. Since it can take out from an exterior body, use becomes easy. In addition, with the first plate portion and the second plate portion being overlaid and holding the contact lens, the lens clip can be picked with a finger and taken out of the bag without touching the contact lens. It is also possible to drain the storage solution, and the convenience can be improved.

An eleventh aspect of the present invention is a contact lens package according to any one of the first to tenth aspects, wherein one of the first plate portion and the second plate portion is the first of them. Compared to the other of the plate portion and the second plate portion, a protruding plate portion is provided that extends and expands relatively large from the portion sandwiching the contact lens toward the outer peripheral side.

In the contact lens package of this aspect, it becomes easier to open the lens clip and take out the contact lens. That is, the lens clip taken out from the package exterior body is picked up by picking up the other plate part with the fingertip of the other hand while holding the protruding plate part of one plate part with the fingertip of one hand. The opening operation can be easily performed.

As is clear from the above description, in the contact lens package having the structure according to the present invention, the contact lens is accommodated in a state of being pressed and deformed, so that it is possible to achieve a compact size by reducing the thickness. The convenience of carrying a large number of stocks and carrying can be greatly improved.

In addition, by adopting a lens clip that can be held in a pressed state with the contact lens sandwiched therebetween, the contact lens can be stably positioned and held in the pressed state, thereby reducing adverse effects associated with deformation of the contact lens. It can be avoided.

The front view of the contact lens package as one Embodiment of this invention. II-II expanded sectional view in FIG. FIG. 2 is a plan view of a developed state of a lens clip constituting the contact lens package shown in FIG. 1. IV-IV enlarged sectional view in FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show a contact lens package 10 as one embodiment of the present invention. The contact lens package 10 has a bag-shaped package exterior body 12, and a storage solution 14 is accommodated in the package exterior body 12 and sealed. In addition, a lens clip 16 is accommodated in the package exterior body 12, and the contact lens 18 is held by the lens clip 16 so as to be immersed in the storage solution 14 and accommodated in the package.

More specifically, as shown in FIGS. 3 and 4, the lens clip 16 has a thin plate shape as a whole. The lens clip 16 has a structure in which a first plate portion 20 and a second plate portion 22 each having a flat plate shape are integrally connected by a connecting portion 23.

Both the first plate portion 20 and the second plate portion 22 are larger than the front shape of the contact lens 18 on the connecting end side by the connecting portion 23, and the pressing area has such a size that the contact lens 18 can be placed thereon. 24 and 26 are provided.

Further, both the first plate portion 20 and the second plate portion 22 extend toward the opposite sides from the

pressing regions

24 and 26 in the connecting direction by the connecting portion 23 (vertical direction in FIG. 3). The

knobs

28 and 30 are formed.

The knob portion 28 of the first plate portion 20 is wider than the knob portion 30 of the second plate portion 22, and greatly extends outward in the connecting direction of the connecting portion 23. It has spread. In the knob portion 28, a portion that greatly extends outward is a protruding plate portion 32. Further, the protruding plate part 32 is provided with unevenness on the front and back sides and is subjected to a non-slip process.

Furthermore, the connecting portion 23 has a narrow plate shape, and linearly connects the first plate portion 20 and the second plate portion 22 between each one end portion. A thin hinge 34 that extends over the entire length in the width direction is formed at an intermediate portion in the length direction of the connecting portion 23. In the hinge portion 34, the cross-sectional area of the connecting portion 23 is reduced and bent. It is easy to deform.

Then, as shown in FIGS. 1 to 3, the first plate portion 20 and the second plate portion 22 are overlapped so as to be folded back at the hinge portion 34 by being bent at the hinge portion 34. It can be done. By superimposing the first plate portion 20 and the second plate portion 22, the

pressing regions

24 and 26 are overlapped so that the contact lens 18 is sandwiched and held between the overlapping surfaces. It has become. In short, in the present embodiment, the

pressing regions

24 and 26 in the first plate portion 20 and the second plate portion 22 are portions that sandwich the contact lens.

Further, a positioning recess 36 as a positioning engagement portion is formed on the overlapping surface of the pressing region 24 of the first plate portion 20. The positioning recess 36 is formed as a recess that opens in the approximate center of the overlapping surface of the pressing region 24 in a circular region having a diameter slightly larger than the outer diameter (DIA) of the contact lens 18.

On the other hand, a circular through window 38 is formed in a substantially central portion of the pressing region 26 of the second plate portion 22. In short, when the lens clip 16 is bent at the hinge portion 34 and the first plate portion 20 and the second plate portion 22 are overlapped, the through window 38 is positioned substantially at the center of the positioning recess 36. ing.

As a result, the contact lens 18 is placed in the positioning recess 36 of the first plate portion 20 and restricted in displacement, so that the first lens portion 20 and the second plate portion 22 are positioned substantially at the center. The

pressing regions

24 and 26 are sandwiched in the lens axis direction (optical axis direction) and held in a pressed deformation state. Further, the central portion of the contact lens 18 where the optical portion is formed is exposed to the outside through the through window 38 of the second plate portion 22, and the first plate portion 20 and the second plate portion 22 are exposed. It is visible from the outside through the through window 38 while being sandwiched between the

pressing regions

24 and 26.

Preferably, the contact lens 18 is disposed in the positioning recess 36 of the first plate portion 20 with the lens concave surface facing the bottom surface of the positioning recess 36, and the lens convex surface in the optical portion is the second plate. It is held in an exposed state through the through window 38 of the portion 22. Thereby, the positioning effect | action by engagement with the outer periphery level | step difference of the positioning recessed part 36 of the edge part of the contact lens 18 is exhibited more effectively. In addition, since the action of the pressing force on the convex surface side of the optical part is reduced by the through window 38, the concern about the adverse effect on the optical characteristics due to the deformation of the optical part can be alleviated or avoided.

Further, the first plate portion 20 and the second plate portion 22 held with the contact lens 18 interposed therebetween are portions that are separated from the

pressing regions

24 and 26 of the contact lens 18, and the

knob portions

28 and 30 are overlapped. ing. Then, by pressing the overlapping portions of the

knob portions

28 and 30 with the fingertips of the hand in the overlapping direction, the contact lens 18 is pushed between the first plate portion 20 and the second plate portion 22. The lens clip 16 can be easily picked and held while applying pressure and holding force.

Further, in the overlapped state of the

knobs

28 and 30, the protruding plate part 32 of the knob 28 of the first plate part 20 extends outward from the knob 30 of the second plate part 22. Therefore, the first plate portion 20 and the second plate can be obtained by picking up the protruding plate portion 32 with the fingertip of one hand and lifting the picking portion 30 of the second plate portion 22 with the fingertip of the other hand. The part 22 can be easily opened.

Then, by opening the first plate portion 20 and the second plate portion 22 in this manner, the entire contact lens 18 sandwiched between the first plate portion 22 and the second plate portion 24 is exposed. It can be used by picking it up with fingers. In particular, in the present embodiment, the contact area of the contact lens 18 with the pressing region 26 of the second plate portion 22 is reduced by the through window 38, so that the first plate portion 20 and the second plate portion 22. When the lens is opened, the contact lens 18 can be stably positioned in the positioning recess 36 of the first plate 22.

By the way, the material of the lens clip 16 having the above-described structure is not particularly limited, and in consideration of manufacturability, cost, stability, strength, etc., polyethylene, polyvinyl chloride, polypropylene, polyamide, etc. A synthetic resin material can be suitably employed. In particular, the lens clip 16 can be advantageously formed as an integrally molded product integrally including the first and

second plate portions

20 and 22 and the connecting portion 23. Further, in order to make the entire size of the contact lens package 10 compact, each part such as the first and

second plate portions

20 and 22 constituting the lens clip 16 has a thickness of about 0.3 to 1.5 mm, for example. Although it is desirable to have a size, it can be appropriately set according to the material, required strength, and the like.

On the other hand, the package exterior body 12 that accommodates the lens clip 16 as described above can be constituted by, for example, a hard resin case or the like, but in the present embodiment, the film-like first sheet 40 and the second sheet 40 are respectively formed. These sheets 42 are overlapped and their outer peripheral edge portions 44 are sealed by welding or the like.

The first sheet 40 and the second sheet 42 may be a hard resin film or a metal sheet such as an aluminum alloy, but are preferably a thin and flexible soft resin film or the like. A laminated film in which a resin layer such as polypropylene is attached to the aluminum layer may be employed. That is, the contact lens 18 to be accommodated preferably includes the first plate portion 20 and the second plate portion 22 which are preferably rigid as compared with the first sheet 40 and the second sheet 42 as described above. It is held by the lens clip 16 and is accommodated in the package exterior body 12. Therefore, the first and

second sheets

40 and 42 are not required to have a high protective strength against the contact lens 18, and a soft film material that can be easily handled, manufactured, opened, and the like can be suitably used.

Further, the first sheet 40 and the second sheet 42 may be entirely or partially transparent. By employing the first and

second sheets

40 and 42 that are at least partially transparent, it is possible to confirm that the lens clip 16 or the like is accommodated, or the contact lens through the through window 38 of the lens clip 16. The presence of 18 can be confirmed.

The first sheet 40 and the second sheet 42 have a proper amount of the lens clip 16 holding the contact lens 18 and an appropriate amount before the outer

peripheral edge portions

44 and 44 are sealed to form a sealed bag structure. The preservation solution 14 is contained inside. For example, at the stage where the first sheet 40 and the second sheet 42 are welded, leaving a part of the outer peripheral edge, the lens clip 16 and the storage solution 14 are put through the unwelded opening, and then applied. The outer peripheral portion of the lens clip 16 is sealed by welding and sealing the opening portion, and the target contact lens package 10 can be manufactured.

In addition, the preservation | save liquid 14 enclosed in a package can be suitably selected according to the material etc. of the contact lens 18 accommodated as conventionally well-known. Moreover, after sealing the package exterior body 12, sterilization treatment by ultraviolet rays, electromagnetic waves, heating, or the like may be performed as necessary.

In the contact lens package 10 having such a structure, the contact lens 18 is accommodated in a compressed state in which the contact lens 18 is pressed slightly in the optical axis direction, and the contact lens is immersed and stored in an uncompressed floating state (equilibrium state). Compared with a blister package having a conventional structure, the thickness dimension can be greatly reduced. Moreover, since the contact lens 18 is stably held in a predetermined compressed state by the lens clip 16, it can be protected from an external force exerted from the outside of the package exterior body 12.

In particular, in the present embodiment, the first sheet 40 of the package exterior body 12 is directly superimposed on the outer surface of the first plate portion 20 of the lens clip 16 while being in contact with the second plate portion of the lens clip 16. The second sheet 42 of the package outer package 12 is directly overlapped with the outer surface of the package 22 in a contact state. The atmospheric pressure exerted via the first sheet 40 and the second sheet 42 is exerted as a pressing force in the overlapping direction on the first plate portion 20 and the second plate portion 22. Thus, a locking means for maintaining the pressed holding state of the contact lens 18 by the lens clip 16 is configured.

Therefore, there is no need to provide a special locking structure for holding the first plate portion 20 and the second plate portion 22 in an overlapped state in the lens clip 16, and the contact lens 18 by the lens clip 16 has a simple structure. It is possible to stably maintain the holding state. However, the two plate portions 20 are formed by forming a concave portion and a convex portion that are engaged and press-fitted with each other at the corresponding positions in the state where the first plate portion 20 and the second plate portion 22 are overlapped. , 22 can also be provided with mechanical locking means for holding them in an overlapped state.

Further, in the present embodiment, the package exterior body 12 in which the lens clip 16 is directly sandwiched between the first sheet 40 and the second sheet 42, both of which are film-shaped as described above, is employed. Thus, the overall thickness dimension of the contact lens package 10 can be further reduced. Therefore, it can be easily and safely carried in a pass case, and a large number can be stacked and efficiently stored in a case such as a small box.

Furthermore, the use of the package outer package 12 configured by sealing the outer peripheral edge portion 44 by overlapping the first and second

soft sheets

40 and 42 each having a film shape, It is also possible to open the package outer package 12 by cutting with fingers. In order to make the opening with fingers easier, it is desirable to make a cut 46 as a cutting start portion in the outer peripheral edge portion 44 of the package exterior body 12.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the specific descriptions in the embodiments, and various changes, modifications, improvements, and the like are added based on the knowledge of those skilled in the art. It should be understood that any of these embodiments can be included in the scope of the present invention without departing from the spirit of the present invention.

For example, in the present embodiment, the positioning engagement portion is formed on the first plate portion 20, but it may not be formed, and the first plate portion 20 and the second plate portion 22 may not be formed. It may be formed on at least one of the overlapping surfaces. Further, the through window may not be formed, or may be formed in at least one of the pressing region 24 and the flange 26 of the first plate portion 20 and the second plate portion 22.
