Description

Container and packing method

The present invention relates to a container for storing an optical element including, for example, a rectangular plate glass and a method for packing an optical element using the container.

For example, a cover glass used for an image sensor of a digital camera is an optical element in which an optical filter such as an IR cut filter is formed on a surface of a plate glass by vacuum deposition or the like. For this type of optical element, a very small rectangular element is used for incorporation into an optical apparatus such as a digital camera. In order to manufacture such an optical element, a method is generally used in which an optical filter is formed on the surface of a large plate glass and then the plate glass is cut into small rectangles. The optical element thus obtained is packaged and stored in a predetermined container until it is incorporated into an optical device, or shipped in a state of being accommodated in the container.

Conventionally, a packaging container that houses optical elements includes a tray-like container body that houses a plurality of optical elements, and a lid that covers the container body. From the viewpoint of being easily detachable from the container main body or effectively protecting the effective surface thereof, the optical element is usually accommodated in the container main body in an upright state. A large number of groove portions are formed in the housing portion of the container body in order to hold a large number of optical elements.

If the upper end of the optical element protrudes from the container body when the optical element is accommodated in the accommodating portion, the right and left sides of the optical element are gripped without touching the effective surface of the optical element. It can be accommodated in or taken out from the accommodating portion, and the handling becomes easy. An optical element is accommodated in a container main body as mentioned above, and is packed by covering this with a lid.

By the way, in order to allow the optical element to be easily attached to and detached from the container body, the groove portion of the accommodating portion has a width slightly larger than the thickness of the optical element. Therefore, in the container, the optical element is in a state where it can move slightly in the direction along the groove, although it is in a limited range. In such a state, the optical element vibrates in the housing portion when the container is transported and the like, and slides between the inner surface of the container body due to the vibration. As a result, a part of the optical element or a part of the container is worn or damaged, so that abrasion powder or broken pieces may be generated in the container. When foreign matters such as abrasion powder generated in this way adhere to the effective surface of the optical element, the optical function is deteriorated.

In order to prevent such dusting of the optical element, Patent Document 1 discloses that the optical element is accommodated in a container body (tray), and the optical element is covered with a flexible protective sheet, and the container body, the protective sheet, A container (containment case) is disclosed in which the inside of the vacuum pack is placed in a vacuum state, and the upper and lower end surfaces of the optical element are clamped by the bottom surface of the container body and the protective sheet. ing. *

In this container, the protective sheet is placed in an unconstrained state on the optical element, so that the protective sheet is pressed against the optical element only by a pressing force generated by a negative pressure without partially generating a strong tensile force (the same document). Paragraph 0027 etc.).

However, when the protective sheet is used in an unconstrained state as described above, the protective sheet may come into contact with the effective surface of the optical element depending on the pitch interval of the optical element, and this may be damaged or contaminated.

JP 2006-131288 A

The inventor of the present application deforms the top plate portion of the lid body covering the container body with tension in order to surely avoid the damage to the effective surface of the optical element as described above, and the top plate portion It came to the idea of pressing the upper end of the optical element.

Specifically, as shown in FIG. 11, the container 100 includes a container main body 102 that houses the optical element 101, a lid 103 that covers the container main body 102, and a compression pack (vacuum pack) 104 that compresses them. Is provided. The container body 102 includes a housing portion 102a that houses the optical element 101, and a flange portion 102c that is connected to the side wall portion 102b of the housing portion 102a. The lid 103 has a top plate portion 103a, a side wall portion 103b connected to the top plate portion 103a, and a flange portion 103c connected to the side wall portion 103b.

In this container 100, a plurality of optical elements 101 are accommodated upright in a container main body 102, and a lid 103 is placed over the container main body 102. At this time, the flange portion 103 c of the lid body 103 is in contact with the flange portion 102 c of the container main body 102. Thereafter, the overlapped container body 102 and lid 103 are accommodated in the compression pack 104, and the air in the compression pack 104 is sucked by a suction device (not shown). Thereby, the compression pack 104 compresses the container main body 102 and the lid 103 by contracting.

As shown by a solid line in FIG. 11, the top plate portion 103 a of the lid body 103 is located at a position away from the optical element 101 before the suction, whereby the top end portion 101 a of the optical element 101 and the top plate portion of the lid body 103. A gap is formed between the terminal 103a and the terminal 103a. When the air in the compression pack 104 is sucked by the suction device, the lid 103 is compressed by the compression pack 104 and has a concave shape so that the top plate portion 103a approaches the upper end portion 101a of the optical element 101 (in FIG. 11). (Denoted by a two-dot chain line). With this deformation, the top plate portion 103 a of the lid 103 comes into contact with the upper end portion 101 a of the optical element 101.

This container 100 can fix each optical element 101 in the accommodation position by the top plate part 103a of the cover body 103 being pressed by the compression pack 104 and pressing the upper end part 101a of each optical element 101. . In this case, tension is generated in the top plate portion 103a deformed into a concave shape, and the top plate portion 103a is about to return to the original flat plate state, so that it is difficult to go around the effective surface side of the optical element 101. It becomes. Therefore, this container 100 can reliably prevent the top plate 103a from coming into contact with the effective surface of the optical element 101.

However, the inventor of the present application has found that the following problems occur in the container 100 having the above-described configuration by further study. When the top plate portion 103a of the lid 103 is deformed into a concave shape and the upper end portion 101a of the optical element 101 is pressed, the degree of deformation of the top plate portion 103a is not constant in the direction of the rows of the optical elements 101, and the center The degree of deformation in the portion side portion increases, and the degree of deformation in the end portion portion decreases. Therefore, the optical element located on the end side of the top plate portion 103a, that is, the optical element 101A located at the head or tail of the row is not suitably pressed by the top plate portion 103a, and the top plate is caused by vibration during container transportation. It was found that abrasion powder was generated due to repeated sliding with the portion 103a and the inner surface of the container body 102.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a container and a packaging method capable of suitably fixing all the contained optical elements in a stable state.

The present invention is to solve the above-described problems, and a container main body that accommodates a plurality of optical elements, a lid that covers the container main body, and a compression pack for compressing the container main body and the lid. The container body includes an accommodating portion that exposes an upper end portion of the optical element and accommodates the optical element in an upright state, and the lid body includes a top plate portion, A side wall portion connected to the top plate portion, and the top plate portion is compressed by the compression pack with the lid body and the container body in a state where the lid body is covered with the container body. It is configured to deform in a convex shape while being in contact with the upper end portions of all the optical elements accommodated in the container body, and to press the upper end portion of the optical element by a tension generated by the convex deformation. And the lid body The regulating portion for regulating the degree of the convex deformation of the plate portion, characterized in that it comprises at least one of the container body and the lid.

According to such a configuration, a plurality of optical elements are accommodated in an upright state in the accommodating portion of the container main body, and the lid is placed on the container main body, and the top plate portion is brought into contact with the upper end portions of all the optical elements. When the container body and the lid are compressed by the compression pack, the top plate portion of the lid is deformed into a convex shape while being in contact with all the optical elements. Due to this deformation, tension is generated in the top plate portion, and the top plate portion presses all the optical elements with this tension. The container can fix the optical element to the accommodation position by this pressing. In this case, by restricting the degree of deformation (deformation amount) of the top plate portion by the restricting portion, the top plate portion presses the optical element with excessive tension, or the pressure by the top plate portion becomes insufficient. Such a situation can be avoided, and all the optical elements can be stably and suitably fixed to the accommodation position with an appropriate tension.

Moreover, according to the container which concerns on this invention, the said control part is a flange part connected with the said side wall part of the said cover body, The said top plate part is obtained when the said flange part contacts a part of said container main body. It is desirable to regulate the degree of the convex deformation at. Further, the restricting portion may be a flange portion formed around the accommodating portion in the container main body, and when the part of the lid body contacts the flange portion, The degree of convex deformation may be regulated. Further, the degree of convex deformation of the top plate of the lid may be regulated by bringing the flange (regulator) of the lid into contact with the flange (regulator) of the container body.

By configuring the restricting portion as a flange portion in this way, it becomes easy to bring a part of the container main body or a part of the lid into contact with the flange portion, thereby making it possible to securely fix the optical element. .

Moreover, this invention is for solving said subject, The container main body which accommodates a some optical element, The cover body covered on the said container main body, For compressing the said container main body and the said cover body A container including a compression pack, wherein the container body is formed around a housing portion that exposes an upper end portion of the optical element and accommodates the optical element in an upright state, and the housing portion. A flange portion, and the lid includes a top plate portion, a side wall portion connected to the top plate portion, and a flange portion connected to the side wall portion, and is not subjected to compression by the compression pack, When the lid body is put on the container body, the top plate portion of the lid body contacts all the optical elements accommodated in the container body, and the flange portion of the lid body includes the container body. From the flange part In the state where the lid and the container main body are compressed by the compression pack, the top plate portion is arranged at the upper end of all the optical elements accommodated in the container main body. The upper end of the optical element is pressed by the tension generated by the convex deformation, and the lid and the container main body are formed by the compression pack. In a compressed state, the flange portion of the lid body is in contact with the flange portion of the container body, thereby restricting the degree of the convex deformation in the top plate portion of the lid body. And

According to such a configuration, a plurality of optical elements are accommodated in an upright state in the accommodating portion of the container main body, and the lid is placed on the container main body, and the top plate portion is brought into contact with the upper end portions of all the optical elements. When the container body and the lid are compressed by the compression pack, the top plate portion of the lid is deformed into a convex shape while being in contact with all the optical elements. Due to this deformation, tension is generated in the top plate portion, and the top plate portion presses all the optical elements with this tension. The container can fix the optical element to the accommodation position by this pressing. In order to generate tension on the top plate, the lid is put on the container body in a state where it is not compressed by the compression pack, and the top plate is brought into contact with the upper ends of all the optical elements accommodated in the container main body. In this case, it is desirable that the flange portion of the lid body is disposed to be opposed to the flange portion of the container body. As a result, there is room in the lid body that allows the top plate portion to be deformed into a convex shape in accordance with the separation distance. Under this condition, the degree of deformation (deformation amount) of the top plate can be regulated by pressing the lid with a compression pack and bringing the flange of the lid into contact with the flange of the container body. Thereby, the situation where a top plate part presses an optical element with excessive tension, or the press by a top plate part becomes inadequate can be avoided. As described above, the container can stably and suitably fix all the optical elements to the accommodation position with an appropriate tension.

In addition, the present invention is for solving the above-described problem, and is a container including a container main body that houses a plurality of optical elements, and a lid body that covers the container main body, An upper end portion of the optical element is exposed, and the optical element is accommodated in an upright state; and a flange portion formed around the accommodating portion, the lid includes a top plate portion, A side wall portion connected to the top plate portion and a flange portion connected to the side wall portion, and the top plate portion is housed in the housing portion when the lid is put on the container body housing the optical element. The flange portion of the lid body is disposed so as to be opposed to the flange portion of the container main body while being in contact with the upper end portions of all the optical elements.

When the lid is compressed in this state, the top plate of the lid can be deformed into a convex shape, but at this time, the top plate of the lid has the flange of the lid from the flange of the container body. During the separation, the convex deformation is continued without being restricted by these flange portions. Moreover, a cover body makes a top-plate part deform | transform into convex shape, and makes the flange part approach the flange part of a container main body. When the flange portion of the lid comes into contact with the flange portion of the container body, the convex deformation of the top plate portion is restricted. By this regulation, the top plate portion is in a state where the convex deformation at that time is maintained without further increasing the deformation amount. In this way, when the top plate portion is brought into contact with the upper ends of all the optical elements accommodated in the container body, the flange portion of the lid body is spaced from the flange portion of the container body and is disposed oppositely. The lid has room to allow the top plate to deform into a convex shape, and the top plate presses all the optical elements with the tension generated by this deformation, and stabilizes them in its accommodation position. Thus, it can be suitably fixed.

In addition, the present invention is for solving the above-described problem, and a first step of storing the plurality of optical elements in the storage portion of the container body, and after the first step, all the top plate portions are The lid is placed on the container body so as to be in contact with the upper end of the optical element, and the flange part of the lid is arranged so as to be opposed to the flange part of the container body. After the step and the second step, the container body and the lid are inserted into the compression pack, air in the compression pack is sucked, and the lid is compressed by the compression pack. The top plate portion is deformed into a convex shape while keeping the top plate portion in contact with the upper end portions of all the optical elements housed in the optical element, and the tension of the optical element is caused by the tension generated by the convex deformation. The top edge A third step of pressing by the top plate portion, and in the third step, the top portion of the lid body by bringing the flange portion of the lid body into contact with the flange portion of the container body. The degree of the convex deformation in the portion is regulated.

According to such a configuration, in the second step, the top plate portion of the lid body is brought into contact with the upper end portions of all the optical elements accommodated in the container body, and the flange portion of the lid body is separated from the flange portion of the container body. By making them face each other, there may be room for allowing the top plate portion to deform into a convex shape on the lid. From this state, when the container main body and the lid are compressed by the compression pack in the third step, the top plate portion of the lid is deformed into a convex shape while being in contact with all the optical elements by this compression. . Due to this deformation, tension is generated in the top plate portion, and the top plate portion presses all the optical elements with this tension. The container can fix the optical element to the accommodation position by this pressing. In this case, the top plate portion presses the optical element with excessive tension by regulating the degree of deformation (deformation amount) of the top plate portion by bringing the flange portion of the lid into contact with the flange portion of the container body. Or the situation where the press by a top-plate part becomes inadequate can be avoided. By this method, all the optical elements can be stably and suitably fixed to their accommodation positions with an appropriate tension.

According to the present invention, it becomes possible to suitably fix all the contained optical elements in a stable state.

The compression pack 5 is sealed after the air inside is sucked.

Hereinafter, a method for packing the optical element 2 using the container 1 having the above configuration will be described.

First, the rectangular optical elements 2 formed in a predetermined size (area) are sequentially accommodated in the container body 3 (first process or accommodation process). At this time, the optical element 2 accommodated in the accommodating portion 6 of the container main body 3 has its side portion fitted into the groove portion 6c of the accommodating portion 6 and is in an upright state, and its upper end portion 2a is from the base portion 7 of the container main body 3. Projecting upward (exposed).

When the predetermined number of optical elements 2 are accommodated, the lid 4 is put on the container body 3 (second step or assembly step). At this time, as shown in FIG. 7, the top plate portion 12 of the lid body 4 is in a state where its inner surface is in contact with the upper end portions 2 a (upper end surfaces) of all the optical elements 2 accommodated in the container body 3. In addition, since the top plate portion 12 is configured in a flat plate shape and all the optical elements 2 housed therein are of the same size, the inner surface of the top plate portion 12 of the lid 4 is connected to the container body 3. It will be in the state which contacted the upper end part 2a of all the optical elements 2 accommodated.

When the lid body 4 is put on the container body 3, the first flange portion 14 of the lid body 4 is in a state of facing the first flange portion 8 of the container body 3. In this case, as shown in FIG. 7, the first flange portion 14 of the lid body 4 is not in contact with the first flange portion 8 of the container body 3, and is at a position spaced upward from the first flange portion 8. Will stay.

Next, as shown in FIG. 8, these are accommodated in the compression pack 5 in a state where the lid body 4 is still on the container body 3 and compressed (third step or compression step). A suction device is connected to the compression pack 5 and suction of air in the compression pack 5 is executed. As the suction proceeds, the compression pack 5 gradually contracts and compresses the container body 3 and the lid body 4.

By being compressed by the compression pack 5, the lid body 4 is deformed into a convex shape (a convex shape upward) with the top plate portion 12 kept in contact with the upper end portion 2 a of the optical element 2. Further, the first flange portion 14 of the lid body 4 approaches the first flange portion 8 of the container body 3 by being compressed by the compression pack 5 as the top plate portion 12 is deformed. Similarly, the second side wall portion 15 of the lid body 4 approaches the side wall portion 9 of the base portion 7 of the container body 3, and the second flange portion 16 approaches the second flange portion 10 of the container body 3. .

It continues to increase until the part 14 contacts the first flange part 8 of the container body 3. When the first flange portion 14 of the lid body 4 comes into contact with the first flange portion 8 of the container body 3, the first flange portion 14 is restrained by the compression of the compression pack 5 and maintains the contact state. Thereby, the increase in the deformation | transformation in the top-plate part 12 stops, and the state with the top-plate part 12 deform | transforming into convex shape is maintained at that time. At this time, the top plate portion 12 of the lid body 4 is deformed into a convex shape to generate tension, and all the optical elements 2 are pressed by this tension.

By such pressing of the top plate 12, the lid 4 presses the upper end portions 2 a of all the optical elements 2 accommodated in the container main body 3, and fixes all these optical elements 2 to their accommodation positions. Will do.

According to the container 1 and the packaging method according to the present embodiment described above, the optical element 2 is accommodated in the accommodating portion 6 of the container body 3, the lid body 4 is covered on the container body 3, and these are accommodated in the compression pack 5. Thus, the top plate portion 12 of the lid 4 can be deformed into a convex shape while being in contact with the upper end portions 2a of all the optical elements 2. The top plate 12 presses and fixes all the optical elements 2 by the tension generated by this deformation.

Moreover, when the 1st flange part 14 of the cover body 4 contacts the 1st flange part 8 of the container main body 3, the increase in a deformation | transformation of the top-plate part 12 stops, At this time, the top-plate part 12 becomes convex shape. The deformed state is maintained. Thus, the 1st flange part 14 of the cover body 4 and the 1st flange part 8 of the container main body 3 can control the deformation | transformation degree of the top-plate part 12 by mutually contacting. That is, each

1st flange part

8 and 14 functions as a control part which controls the degree of a deformation | transformation of the top-plate part 12 (Hereafter, common code |

symbols

8 and 14 are used for each flange part and a control part).

In this way, by restricting the degree of deformation of the top plate portion 12 by the regulating

portions

8 and 14, the top plate portion 12 presses the optical element 2 with an excessive force, or the top plate portion 12 does not press. The situation where it becomes insufficient can be avoided. Thereby, the container 1 can fix the optical element 2 stably and suitably with moderate tension. Further, by restricting the degree of deformation of the top plate 12 by the restricting

portions

8 and 14, it is possible to prevent the lid body 4 from being deformed too much and greatly deviating from the original shape. Even if they are stacked up and down, they do not break the balance.

When the compression pack 5 is opened when the optical element 2 is taken out, the top plate portion 12 that has been deformed into a convex shape is restored to the original flat plate shape, and the first flange portion 14 of the lid 4 is The first flange portion 8 of the container body 3 is separated, and similarly, the second flange portion 16 of the lid body 4 is also separated from the second flange portion 10 of the container body 3. Accordingly, a gap is generated between the second flange portion 16 of the lid body 4 and the second flange portion 10 of the container body 3, and the lid body 4 can be easily detached from the container body 3. As a result, it is possible to efficiently take out the optical element 2 after opening at the shipping destination.

FIG. 9 shows a second embodiment of the container according to the present invention. In said 1st Embodiment, although the 1st flange part 14, the 2nd side wall part 15, and the 2nd flange part 16 were provided in the cover body 4, in this embodiment, the cover body 4 has these. It is comprised only by the top-plate part 12 and the side wall part 13 connected to this top-plate part 12.

The base portion 7 of the container body 3 includes the first flange portion 8, the side wall portion 9, and the second flange portion 10 as in the first embodiment, but in the present embodiment, the first flange portion 8 has a recess 18. Is different from the first embodiment.

In this embodiment, the lid body 4 is put on the container body 3 containing the optical element 2, and these are accommodated in the compression pack 5 and compressed, so that the top 12 is convex as in the first embodiment. Deform. At this time, the side wall portion 13 of the lid body 4 is fitted into the concave portion 18 formed in the first flange portion 8 of the container body 3, thereby restricting the degree of deformation of the top plate portion 12. Thus, the 1st flange part 8 and its recessed part 18 of the container main body 3 function as a control part which controls the deformation | transformation degree of the top-plate part 12 by contacting a part of the top-plate part 12. FIG. Accordingly, the container 1 can stably and suitably fix all the optical elements 2 accommodated in the container body 3.

FIG. 10 shows a third embodiment of the container according to the present invention. In the first embodiment, the first flange portion 8, the side wall portion 9, and the second flange portion 10 are provided on the base portion 7 of the container body 3. However, in the present embodiment, the container body 3 has these. Not done. In this embodiment, when the side wall part 6b of the accommodating part 6 contacts the 1st flange part 14 of the cover body 4, the convex-shaped deformation | transformation in the top-plate part 12 will be controlled. Thus, in this embodiment, the 1st flange part 14 of the cover body 4 functions as a control part which controls the degree of deformation | transformation of the top-plate part 12 by contacting a part of container main body 3. FIG. Accordingly, the container 1 can stably and suitably fix all the optical elements 2 accommodated in the container body 3.

In addition, this invention is not limited to the structure of the said embodiment, It is not limited to the above-mentioned effect. The present invention can be variously modified without departing from the gist of the present invention.

In the above embodiment, an example in which the two container parts 6 are formed in the container body 3 is shown, but the present invention is not limited to this, and the number of the container parts 6 may be 1 or 3 or more.

In said embodiment, the 1st flange part 8 of the container main body 3 and the 1st flange part 14 of the cover body 4 were illustrated as a control part which controls the degree of the convex-shaped deformation | transformation in the top-plate part 12 of the cover body 4. FIG. However, it is not limited to this. For example, the second flange portion 10 of the container body 3 and the second flange portion 16 of the lid body 4 may function as the restricting portion. When the restricting portion is formed in a shape other than these flange portions, in addition to the concave portion 18 exemplified in the third embodiment, a protrusion that contacts and locks a part of the lid 3 is formed on the container body 3. The protrusion 3 or the recess may be formed in a part of the lid 3 and brought into contact with a part of the container body 3 to regulate the degree of deformation of the top plate 12 of the lid 3. You may do it.
