Description

The present invention relates to a contact lens package and a set thereof.

Patent Document 1 describes a disposable contact lens package,
a) a rigid support having an upper surface and a lens mounting surface located on the upper surface;
and b) means for releasably, frictionally attaching two of said packages to one another in a stacked relationship.

Special Publication No. 11-508172

The inventor's research revealed the following problems:

In recent years, contact lens packages are not only handed over at contact lens specialty stores or eyeglass stores, but are also mailed. When mailing, a large number of contact lens packages (for example, several dozen) are packed into a box. This box is then dropped into the mailbox of the purchaser's home.

By adopting a contact lens package that can combine two contact lens packages of the same shape, such as the contact lens package described in Patent Document 1, it is possible to save space. However, the inventor's research has revealed that, depending on the size of the mailbox, a box filled with contact lens packages may not be able to pass through. If the box cannot be posted in the mailbox, it will usually be subject to redelivery.

In recent years, the number of parcels handled by home delivery services has increased due to the expansion of e-commerce and other factors. Of these parcels, redelivery accounts for approximately 20% of all deliveries. Issues such as increased costs, labor shortages, and _CO2 emissions due to redelivery have become major social issues.

In order to reduce the height of the box and reduce the possibility of redelivery, the vertical height of two contact lens packages combined vertically can be kept at the same level as the vertical height of one contact lens package. On the other hand, in the case of the contact lens package described in Patent Document 1, as shown in Figure 6 of Patent Document 1, the height of two contact lens packages combined vertically is greater than the vertical height of one contact lens package by an amount close to the thickness of the rigid support (the support portion as referred to in this specification).

The object of the present invention is to make the vertical height of two contact lens packages combined vertically equal to the vertical height of one contact lens package.

The following describes in detail the embodiments of the present invention with reference to the drawings. Note that any content not described in this specification may adopt the configuration of a known contact lens package.

The contact lens package according to this embodiment has the following configuration.
"A storage compartment for contact lenses,
A support portion that supports the storage portion;
A contact lens package comprising:
The storage portion is recessed from the support portion,
When the concave direction is downward and the opposite direction is upward,
The support part is
A protrusion formed downward;
a through-hole formed of at least one of a notch and a through-hole in the support portion;
Equipped with
A contact lens package having a configuration in which, when a virtual contact lens package having the same shape as the contact lens package is rotated 180 degrees from top to bottom and placed on a horizontal table, and the protrusion is fitted so as to fit within the virtual through-hole, the tip of the virtual protrusion is fitted so as to fit within the through-hole when the virtual contact lens package is placed on the horizontal table.

As described above, in this embodiment, the recessed direction of the storage section (the protruding direction of the storage section when viewed from the side) is defined as downward (the direction from top to bottom), and the opposite direction is defined as upward (the direction from top to bottom). In other words, the surface formed by the support section (the edge of the hole) near the storage section is defined as the horizontal plane, the direction perpendicular to this is defined as the up-down direction, and the recessed direction is defined as downward. When the contact lens package is viewed from below, it is defined as a bottom view, and when the contact lens package is viewed from above, it is defined as a top view. The up-down direction is defined as the Z direction, the upward direction is defined as the +Z direction, and the downward direction is defined as the -Z direction.

The long direction in which the storage section and the opening described below are aligned when the support section of the contact lens package is viewed from above is defined as the Y direction, the direction from the opening toward the storage section is defined as the +Y direction, and the opposite direction is defined as the -Y direction. The short direction perpendicular to the Z and Y directions when the support section of the contact lens package is viewed from above is defined as the X direction, the side on which the protrusion and through-hole are provided is defined as the +X direction, and the opposite direction is defined as the -X direction.

In this specification, "rotating the contact lens package 180 degrees from top to bottom" refers to rotation around the X-axis direction as the axis of rotation.

In this specification, the "outer edge" refers exactly as the name suggests, for example to the end of the support part when viewed from above. The "inner side" of the outer edge is the opposite side to the side facing the outer edge, for example, referring to the direction away from the outer edge of the support part.

The contact lens package set according to this embodiment has the following configuration.
"A contact lens package set is a combination of contact lens packages A and B, with contact lens package B of the same shape as contact lens package A rotated 180 degrees from top to bottom,
The protruding portion of the contact lens package A is fitted into the through-hole of the contact lens package B, and
When the through-hole of the contact lens package A and the protruding portion of the contact lens package B are fitted together,
A contact lens package set in which the vertical width of the contact lens package set is equal to the vertical width of contact lens packages A and B.

Two contact lens packages according to this embodiment are prepared, and designated as A and B, A is in the normal position (the recess direction is downward, and the protruding portion 3a protrudes downward), and B is rotated 180 degrees from top to bottom around the X-axis direction as the rotation axis (i.e., the recess direction is upward, and the protruding portion 3b protrudes upward), and B in this state is brought close to A, whereby the protruding portion 3a of A and the penetrating portion 4b of B are fitted together as shown in FIG. 5. At the same time, the penetrating portion 4a of A and the protruding portion 3b of B are fitted together. The fitting of the two is also simply referred to as "combination." The symbol indicating the configuration of A has an a suffix (or no mark) added to the end, and the symbol indicating the configuration of B has a b suffix added to the end.

The technical concept of the present invention is reflected not only in the set of contact lens packages A and B combined vertically, but also in the contact lens package itself. In order to explain the configuration of the contact lens package itself (contact lens package A is exemplified), contact lens package B will be mentioned. In this case, contact lens package B will also be referred to as a virtual contact lens package, and in this specification, the word "virtual" will be added to the beginning of the word of each part (e.g., protrusion 3) that constitutes the virtual contact lens package (e.g., virtual protrusion 3).

The contact lens package A according to this embodiment includes a storage section 1 for storing a contact lens, and a support section 2 that contacts the storage section 1 and supports the storage section 1.

The storage section 1 and the support section 2 may be integrally molded from resin, and the contact lens package A may be disposable.

The storage section 1 is recessed when viewed from the support section 2, and there is no limitation on the shape of the storage section 1 as long as a contact lens (not shown) can be placed inside the recess. In this embodiment, the storage section 1 is exemplified as a roughly spherical or roughly elliptical bowl. In other words, the contact lens can be placed on the top bottom 11 of the bowl.

When actually placing the contact lens in the bowl, a sealing member (seal) (not shown) may be attached to the edge of the bowl (and possibly to the portion 21 of the support part 2 adjacent to the bowl) to seal the inside of the bowl.

At this time, the bowl-nearby portion 21 of the support portion 2 may be sealed using heat fusion. A step 22 connects the bowl-nearby portion 21 of the support portion 2 and the bowl, which is the storage portion 1. The step 22 is a part of the support portion 2. A taper may be used instead of the step.

There are no limitations on the shape of the support part 2, so long as it can contact the storage part 1 and support the storage part 1, except for the configurations (projection part 3, penetration part 4, opening part 5, notch part 6, and bent part 7) provided on the support part 2 described below. Except for the configurations described below, the support part 2 may be a plate-like shape that is generally rectangular when viewed from above. In this embodiment, an example is shown in which the storage part 1 is recessed downward relative to the plate-like support part 2.

The support part 2 has a protrusion 3 formed downward from the underside of the support part 2, and a through-hole 4 consisting of at least one of a notch and a through-hole in the support part 2. In this embodiment, a case where the periphery of the support part 2 is notched is illustrated, but a through-hole hollowed out in a part other than the periphery of the support part 2 may also be used.

In this embodiment, either the notch or the through hole that fits into the protrusion 3 is referred to as the through hole 4 in order to distinguish it from the notch 6 (described later) that is a notch in the corner of the support part 2 and the opening 5 (described later) that is formed in the support part 2 alongside the storage part 1.

In this embodiment, when a virtual contact lens package (i.e., B) having the same shape as contact lens package A is rotated 180 degrees from top to bottom and placed on a horizontal stand S, the protrusion 3a is fitted so as to fit within the virtual penetration portion 4b. When the protrusion 3a is placed on the horizontal stand S, the tip of the virtual protrusion 3b is fitted so as to fit within the penetration portion 4a.

In this specification, "fitting within the through-hole 4 (or opening 5 described below)" means that the object is positioned within the closed area that forms the through-hole or notch, i.e., within the area that is hollowed out from the support part 2 before the through-hole or notch is provided, or in other words, that the object does not protrude from the area. The term "within the area" also includes cases where the object is in contact with the boundary of the area. As an example, "the lower surface bottom 12a of the storage part 1a fits within the opening 5b" means that the apex of the lower surface bottom 12a does not protrude from the opening 5b.

When the contact lens package A is rotated 180 degrees from top to bottom and the virtual contact lens package B is placed on the horizontal stand S, it is preferable that the posture of the protruding portion 3a that is fitted to fit within the virtual through-hole 4b when placed on the horizontal stand S coincides with the posture of the contact lens package A alone when placed on the horizontal stand S. In other words, it is also preferable in terms of posture stability when placed still, that the contact lens package A in the contact lens package set according to this embodiment can stand on its own on the horizontal stand S even when set, just as it does when it is alone.

On the other hand, it is acceptable for another protruding part (not shown) that is in contact with the ground when placed stationary on the horizontal stand S in the standalone state to be placed on the underside of the support part 2 of B in the set state. However, in this case, a configuration is adopted in which the set state does not have a larger vertical height than the standalone state.

When the unit is placed on the horizontal stand S by itself, the protrusion 3a is preferably used as the grounding point. A different protrusion (not shown) other than the protrusion 3a may be provided as the grounding point. In this case, it is preferable to provide a different through-hole (not shown) in B that corresponds to the different protrusion in A. The bottom 12 of the lower surface of the storage unit 1 may be used as the grounding point. The corners (-X direction, -Y direction) of the support unit 2 described below may be bent downward as the grounding point at the bent portion 7. When at least the protrusion 3, the lower surface of the storage unit 1, and the bent portion 7 described below are used as the grounding points, the unit is supported at three points, which is preferable because it provides a stable stationary state on the horizontal stand S.

When the protrusion 3a of the contact lens package A is fitted into the through-hole 4b of the contact lens package B, it is preferable that the opening 5a is formed in a position and shape that allows it to fit into the apex of the bottom 12b of the lower surface of the recess of the virtual storage section 1b.

When this configuration is adopted, when the contact lens packages of this embodiment are combined, the lower bottom portion 12b of the storage portion 1b of B can be accommodated in the opening 5a of the support portion 2a of A, as shown in Figure 6, thereby achieving further space savings.

The position and shape of the opening 5 are not limited as long as the fitting can be achieved. For example, the shape of the opening 5 may be elliptical, circular, rectangular, polygonal, or any other shape when viewed from above.

It is preferable that the vertical width of the protruding portion 3 is equal to the vertical width of the storage portion 1. In this case, the protruding portion 3 and the storage portion 1 become the ground contact points. In addition, the vertical widths of these become equal to the vertical widths when the device is set.

In this specification, "vertical width" refers to the maximum vertical width when contact lens packages A and B are placed individually on horizontal stand S, or when the combined set of A placed on top and B placed on the bottom is placed on horizontal stand S.

In this specification, "equal" includes a perfect match and a substantially equal match. "Substantially equal" also includes a difference between the two of less than 0.50 mm (preferably less than 0.30 mm, and more preferably less than 0.10 mm), for example.

In this embodiment, the protrusion 3 protrudes from the outer edge of the lower surface of the support part 2, but the present invention is not limited to this case. However, in consideration of space saving when the contact lens packages A and B are combined, it is preferable that the protrusion 3 protrudes downward from the outermost edge of the support part 2 or its vicinity (for example, more than 0 mm and less than 2 mm inside).

Furthermore, if the protrusion 3 and the through-hole 4 are formed on the outer edge of the support part 2 so that they are in contact with each other, it is possible to further save space and to easily align them when combining them. However, the protrusion 3 and the through-hole 4 may be formed with a distance between them (for example, a distance of more than 0 mm and less than 5 mm). Ultimately, as long as the arrangement of the through-hole 4 of A and the position of the protrusion 3 of B are symmetrical (for example in the Y direction), A and B can be combined, so there is no restriction on whether there is a distance between the protrusion 3 and the through-hole 4.

The shape of the protrusion 3 (bottom view, side view) is not limited. In addition, it is useful for the protrusion 3 to be molded integrally with the support part 2 from plastic or the like in disposable applications, but this is not essential.

It is also possible to provide a separate small protrusion 31 on the inside of the protrusion 3. In this case, the small protrusion 31 may protrude inward so as to come into contact with the underside of the support part 2 as shown in Figures 2 and 3, or it may protrude inward so as not to come into contact with the underside of the support part 2. In either case, the small protrusion 31 acts as a reinforcing material (rib) for the protrusion 3, thereby preventing damage to the protrusion 3.

The shape of the through-hole 4 may be determined according to the shape of the tip of the protrusion 3. When the through-hole 4 is a notch when the contact lens package is viewed from above, the outermost edge of the notch (the opening of the notch) may be wider than its inner side (for example, the part 1 mm inside from the outermost edge). There is no limit to the width of the innermost side of the notch (the bottom of the notch), but if it is narrower than the outermost edge of the notch (the opening of the notch), this is preferable because it makes it easier to detach the protrusion 3 and facilitates the release of the combined state of the contact lens packages.

For example, if the through portion 4 is a notch, the outer edge of the notch may be chamfered or rounded. This makes it easier to insert and remove the protrusion 3 of B from the outer edge into the notch of A (i.e., easier to insert and remove).

When the contact lens package is viewed from above, it is preferable that the protrusion 3 and the through-hole 4 are formed on the same side (+X direction) of the support part 2.

When contact lens packages using this configuration are combined and it is desired to release the combination, the mated state can be easily released by lifting the upper contact lens package A.

Furthermore, it is preferable that a notch 6 is formed in the support portion 2 by cutting out a corner (+X direction, -Y direction) on the side away from the storage portion 1 (-Y direction) and on the same side (+X direction) as the protrusion portion 3 and the through portion 4 are formed.

When two contact lens packages using this configuration are combined and it is desired to release the combination, the mated state can be easily released by inserting a finger into the notch 6, lifting the upper contact lens package A, and flipping it in the -X direction.

In the support section 2, the corner (-X direction, -Y direction) that is on the side away from the storage section 1 and that faces the above corner (+X direction, -Y direction) is preferably a bent section 7 formed by bending the corner (-X direction, -Y direction) downward. In this embodiment, the bent section 7 is configured separately from the protruding section 3.

The vertical width of the bent portion 7 is preferably equal to the vertical width of the protruding portion 3. More preferably, the vertical width of the bent portion 7 is equal to the vertical width of the protruding portion 3 and the vertical width of the storage portion. The downward bending angle of the bent portion 7 may be set appropriately to satisfy these conditions. Also, as shown in FIG. 7, the dimensions of the bent portion 7a may be set so that it comes into horizontal contact with the corners (-X direction, -Y direction) of the support portion 2b of the contact lens package B when it touches the horizontal table S.

By adopting this configuration, the corners (-X direction, -Y direction) of the support part 2 can be set as the grounding points. With this setting, at least the protrusion 3 and the bent part 7 can be set as the grounding points. By increasing the grounding area of the protrusion 3 and the bent part 7, stable support at two points is possible. On the other hand, if at least the protrusion 3, the bottom part 12 of the lower surface of the storage part 1, and the bent part 7 described below are set as the grounding points, support will be provided at three points, which is preferable because the resting state on the horizontal stand S will be more stable.

The technical scope of the present invention is not limited to the above-described embodiments, but also includes forms with various modifications and improvements within the scope that can derive specific effects obtained by the constituent elements of the invention and their combinations.

The contact lens package set of this embodiment employs a configuration in which two contact lens packages A and B are fixed simply by being placed on top of each other, rather than being fixed by friction, as described in Patent Document 1. In other words, as a means for fixing contact lens packages of the same shape, the two are fitted together, but are loosely fixed by simply placing contact lens package A on contact lens package B without friction. On the other hand, as a means for fixing the contact lens packages, in addition to the configuration in this embodiment in which they are fixed simply by being placed on top of each other, engagement using friction may also be employed. For example, the bent portion 7a of A can be engaged by friction with the corners (-X direction, +Y direction) of the support portion 2b of B on the side of the storage portion 1b.

This embodiment makes it possible to make the vertical height of two contact lens packages combined vertically equal to the vertical height of one contact lens package. Furthermore, by adopting a preferred example, it becomes easier to release the combined contact lens packages. However, the fixing force is reduced.

To supplement this fixing force, it is preferable to use the bent portion 7a (-X direction, -Y direction) of A to frictionally engage with the corner (-X direction, +Y direction) of the support portion 2b of B on the housing portion 1b side. To achieve frictional engagement, the bending direction and dimensions of the bent portion 7 (-X direction, -Y direction) or the shape of the corner (-X direction, +Y direction) of the support portion 2 may be set. Note that even in this case, the combination state can still be easily released. This is because the engagement between the protrusion 3a and the through portion 4b described above is easily released, and furthermore, if a finger is inserted into the notch 6a and A is lifted up, the frictional engagement by the bent portion 7 of A can be easily released.

In this embodiment, a protrusion 3 separate from the storage section 1 and a through-hole 4 corresponding to the protrusion 3 are provided. On the other hand, the storage section 1 may be recessed downward. In other words, when the contact lens packages A and B are combined, the storage section 1a may be grounded on the horizontal stand S.

In that case, in order to enable A alone to stand on its own when placed on a horizontal stand S, bent portion 7a at the corner of support portion 2a may be used instead of protruding portion 3a in this embodiment. In order to improve stability when it stands on its own, the corners (+X direction, -Y direction) of support portion 2a may not be cut out, and bent portion 7a may extend from corner (-X direction, -Y direction) of support portion 2a to corner (+X direction, -Y direction). Alternatively, instead of cutting out the corners (+X direction, -Y direction) of support portion 2a, another bent portion may be used.

In addition, in order to improve stability when the storage unit 1a stands on its own, a cross-shaped protrusion (not shown) may be provided as part of the bottom surface 12 of the storage unit 1a as viewed from below, as shown in FIG. 2 of Patent Document 1, so that the bottom surface 12a of the storage unit 1a makes surface contact with the horizontal stand S rather than point contact.

The configuration including the above-mentioned modified examples is as follows. In the configuration below, since the bent portion 7 can be considered to be protruding downward, it is considered to be a type of the protruding portion 3. In that case, the protruding portion 3 described so far may be called the first protruding portion, and the bent portion 7 may be called the second protruding portion. Similarly, the opening portion 5 is also considered to be a type of the through portion 4. In that case, the through portion 4 described so far may be called the first through portion, and the opening portion 5 may be called the second through portion.
