Description

  The present invention relates to a container for accommodating an optical element including, for example, a rectangular sheet glass, and a method for packaging an optical element using the container.

  For example, a cover glass used for an image sensor of a digital camera is an optical element formed by forming an optical filter such as an IR cut filter on a surface of a plate glass by vacuum deposition or the like. As this type of optical element, a very small rectangular one is used to be incorporated into an optical apparatus such as a digital camera. In order to produce such an optical element, usually, an optical filter is formed on the surface of a large-sized 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 or shipped in a container while being incorporated into the optical device.

  Conventionally, a container for packing which accommodates an optical element is provided with a tray-like container main body which accommodates a plurality of optical elements, and a lid which is put on the container main body. The optical element is usually accommodated in the container portion of the container body in an upright state, from the viewpoint of easy attachment and detachment with respect to the container body or effective protection of the effective surface thereof. In order to hold a large number of optical elements, a large number of grooves are formed in the housing portion of the container body.

  When the upper end of the optical element is projected from the container body when the optical element is accommodated in the accommodation portion, the left and right sides of the optical element are gripped without touching the effective surface of the optical element. , Or can be taken out of the containing portion, which facilitates its handling. The optical element is housed in the container body as described above, and is packaged by putting a lid on it.

  By the way, in order to make it easy to attach and detach an optical element with respect to a container main body, the groove part of the accommodating part has a width | variety slightly larger than the thickness of an optical element. Therefore, in the container, the optical element can move slightly in the direction along the groove, although in a limited range. In such a state, the optical element vibrates in the housing during transport of the container or the like, and slides with the inner surface of the container body due to the vibration. As a result, wear dust or broken pieces may be generated in the container due to wear or breakage of a part of the optical element or a part of the container. When foreign substances such as wear powder generated in this manner adhere to the effective surface of the optical element, the optical function is degraded.

  In order to prevent such dust generation of the optical element, Patent Document 1 accommodates the optical element in a container body (tray) and covers the optical element with a flexible protective sheet, and the container body and the protective sheet A container (housing case) is disclosed in which the space between the upper and lower end surfaces of the optical element is clamped by the bottom surface of the container body and the protective sheet by placing the ing.

  In this container, by covering the optical element with the protective sheet in a non-restrained state, the protective sheet is brought into pressure contact with the optical element only with the pressing force generated by the negative pressure without partially generating a strong tensile force (the same document) See paragraph 0027 of

  However, when the protective sheet is used in the unconstrained state as described above, depending on the pitch of the optical elements, the protective sheet may contact, damage or contaminate the effective surface of the optical element.

  The inventor of the present invention deforms the top plate portion of the lid to be put on the container main body with tension so as to reliably avoid the damage to the effective surface of the optical element as described above, and the top plate portion We came up with the idea of pressing the upper end of the optical element.

  Specifically, as shown in FIG. 11, the container 100 includes a container body 102 for housing the optical element 101, a lid 103 to be put on the container body 102, and a compression pack (vacuum pack) 104 for compressing these. Equipped with The container body 102 has a housing portion 102a for housing the optical element 101, and a flange portion 102c 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 the container 100, the plurality of optical elements 101 are accommodated upright in the container body 102, and the lid body 103 is placed on the container body 102. At this time, the flange portion 103 c of the lid 103 comes in contact with the flange portion 102 c of the container main body 102. Thereafter, the container body 102 and the lid 103 which are superposed 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 body 102 and the lid 103 by contracting.

  The top plate portion 103 a of the lid body 103 is at a position away from the optical element 101 before suction as shown by the solid line in FIG. 11, whereby the top plate portion of the optical element 101 and the top plate portion of the lid body 103 A gap is formed between it and 103a. When air in the compression pack 104 is sucked by the suction device, the lid 103 is pressed by the compression pack 104 and is concaved so that the top plate portion 103a approaches the upper end portion 101a of the optical element 101 (in FIG. (Denoted by a two-dot chain line). By this deformation, the top plate portion 103 a of the lid body 103 contacts the upper end portion 101 a of the optical element 101.

  In the container 100, when the top plate portion 103a of the lid 103 is pressed by the compression pack 104 to press the upper end portion 101a of each optical element 101, each optical element 101 can be fixed at the storage position. . In this case, since tension is generated in the concavely deformed top plate portion 103a and the top plate portion 103a is going to return to the original flat state, it is difficult to get around the effective surface side of the optical element 101 It becomes. Therefore, the container 100 can reliably prevent the top plate portion 103 a 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 as a result of further examination. When the top plate portion 103a of the lid 103 is deformed in a concave shape to press the upper end portion 101a of the optical element 101, the degree of deformation of the top plate portion 103a is not constant in the direction of the row of the optical elements 101, but the center thereof The degree of deformation at the part side becomes greater, and the degree of deformation at the end side becomes smaller. For this reason, the optical element located at 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 vibrated during container conveyance. It was found that the sliding with the portion 103a and the inner surface of the container main body 102 was repeated, and this caused wear powder.

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

  The present invention is intended to solve the above-mentioned problems, and a container body for accommodating a plurality of optical elements, a lid to be put on the container body, and a compression pack for compressing the container body and the lid. And the container main body includes an accommodating portion for exposing the upper end portion of the optical element and accommodating the optical element in an upright state, and the lid includes a top plate portion; And a side wall portion connected to the top plate portion, wherein the top plate portion is compressed by the compression pack by the lid body and the container body in a state where the lid body is covered with the container body. While being in contact with the upper end of all the optical elements contained in the container main body, it is deformed in a convex shape, and the upper end of the optical element is pressed by the tension generated by the convex deformation. The lid of the lid 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 this configuration, the plurality of optical elements are housed upright in the housing portion of the container body, the lid is placed on the container 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 in a convex shape while in contact with all the optical elements by this compression. Due to this deformation, a 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 in its storage position by this pressing. In this case, by regulating the degree of deformation (the amount of deformation) of the top plate portion by the regulating portion, the top plate portion presses the optical element with an excessive tension or the pressing by the top plate portion becomes insufficient Such a situation can be avoided, and all the optical elements can be stably and suitably fixed in the storage position with an appropriate tension.

  Further, according to the container of the present invention, the restricting portion is a flange portion connected to the side wall portion of the lid, and the top plate portion is brought into contact by the flange portion contacting a portion of the container body. It is desirable to regulate the degree of said convex deformation in. In addition, the restriction portion may be a flange portion formed around the accommodation portion in the container main body, and a part of the lid contacts the flange portion, whereby the top plate portion The degree of convex deformation may be regulated. In addition, 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 thus configuring the restriction portion as the flange portion, it becomes easy to make a part of the container main body or a part of the lid come in contact with the flange portion, which makes it possible to securely fix the optical element. .

  Further, the present invention is for solving the above-mentioned problems, and for compressing a container main body for accommodating a plurality of optical elements, a lid to be put on the container main body, the container main body and the lid. A container comprising a compression pack, wherein the container main body is formed around an accommodating portion for exposing the upper end portion of the optical element and accommodating the optical element in an upright state, and the periphery of the accommodating portion The cover 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 lid body does not receive compression by the compression pack. When the lid body is covered with the container body, the top plate portion of the lid contacts all the optical elements contained in the container body, and the flange portion of the lid body is the container body Away from the flange of And the top plate portion is the upper end portion of all the optical elements accommodated in the container main body in a state where the lid and the container main body are compressed by the compression pack. And 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 compressed by the compression pack. In the compressed state, the flange portion of the lid contacts the flange portion of the container body, thereby restricting the degree of convex deformation of the top plate portion of the lid. Do.

  According to this configuration, the plurality of optical elements are housed upright in the housing portion of the container body, the lid is placed on the container 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 in a convex shape while in contact with all the optical elements by this compression. Due to this deformation, a 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 in its storage position by this pressing. In order to generate tension in the top plate, in a state not subjected to compression by the compression pack, cover the container body with the lid, and contact the top plate to the upper end of all the optical elements contained in the container body. Preferably, the flange portion of the lid body is spaced apart from the flange portion of the container body so as to be oppositely disposed. As a result, the lid has room for allowing the top plate to be deformed in a convex shape in accordance with the separation distance. Under this condition, the degree of deformation (amount of deformation) of the top plate can be regulated by pressing the lid with the compression pack and bringing the flange of the lid into contact with the flange of the container body. As a result, it is possible to avoid the situation where the top plate portion presses the optical element with excessive tension or the pressing by the top plate portion becomes insufficient. Thus, the container can stably and suitably fix all the optical elements in the storage position with a suitable tension.

  Further, the present invention is to solve the above-mentioned problems, and is a container comprising a container main body for housing a plurality of optical elements, and a lid to be put on the container main body, wherein the container main body is The housing includes: a housing portion for exposing the upper end portion of the optical element and housing the optical element in an upright state; and a flange portion formed around the housing portion, wherein the lid body is a top plate portion The top plate is accommodated in the accommodating portion when the lid body is covered with the container body containing the optical element, and the side wall portion connected to the top plate portion and the flange portion connected to the side wall portion. In addition to being in contact with the upper end portions of all the optical elements, the flange portion of the lid is disposed so as to be apart from and facing the flange portion of the container body.

  As described above, in the present invention, when the lid is put on the container body, the top plate portion of the lid contacts the upper end portions of all the optical elements contained in the container body, and the flange portion of the lid It will be positioned to face away from the flange portion of the container body. In this state, if the lid is compressed, the top plate portion of the lid can be deformed in a convex shape, but at this time, in the top plate of the lid, the flange portion of the lid is from the flange portion of the container main body While being separated, the convex deformation continues without being restricted by these flanges. In addition, the lid deforms the top plate in a convex shape, and causes the flange to approach the flange of the container body. When the flange portion of the lid contacts the flange portion of the container main body, the convex deformation of the top plate portion is restricted. Due to this restriction, the top plate portion maintains the convex deformation at that time without increasing the amount of deformation further. Thus, when the top plate portion is brought into contact with the upper end portions of all the optical elements accommodated in the container main body, the flange portion of the lid is disposed to face the flange portion of the container main body, The lid has room to allow the top plate to be deformed in a convex manner, and the top plate presses all the optical elements with the tension generated by this deformation and stabilizes them in their storage position Can be suitably fixed.

  Further, the present invention is for solving the above-mentioned problems, and a first step of accommodating the plurality of optical elements in the accommodation portion of the container main body, and all of the top plate portion after the first step. The cover is placed on the container body to be in contact with the upper end of the optical element, and the flange of the cover is disposed to face the flange of the container at a distance After the step and the second step, the container body and the lid are inserted into the compression pack, the air in the compression pack is sucked, and the container pack is compressed by pressing the lid with the compression pack. While the top plate portion is in contact with the upper end portion of all the optical elements contained in the top plate portion, the top plate portion is deformed in a convex shape, and the tension generated by the convex shape deforms the optical element Top end front And a third step of pressing by a top plate portion, wherein, in the third step, the top plate portion of the lid is brought into contact by bringing the flange portion of the lid into contact with the flange portion of the container body. The present invention is characterized in that the degree of the convex deformation is restricted.

  According to this configuration, in the second step, the top plate of the lid is brought into contact with the upper ends of all the optical elements contained in the container body, and the flange of the lid is separated from the flange of the container body By making the lid face each other, there may be room for the lid to allow the top plate to be deformed in a convex shape. From this state, in the third step, when the container body and the lid are compressed by the compression pack, the top plate portion of the lid is deformed in a convex shape while keeping in contact with all the optical elements by this compression. . Due to this deformation, a 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 in its storage position by this pressing. In this case, the top plate portion presses the optical element with an excessive tension by restricting the degree of deformation (the amount of deformation) 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 pressing by the top plate becomes insufficient can be avoided. According to this method, all optical elements can be stably and suitably fixed in the storage position with an appropriate tension.

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

The top plate 12 has a projection 17 which positions each container 1 when the containers 1 are vertically stacked. The projection 17 is formed in a rectangular shape in plan view as shown in FIG. When a plurality of containers 1 are stacked, the projection 17 of the lid 4 associated with the lower positioned container 1 is positioned between the two containers 6 of the container body 3 associated with the upper container 1. It will be. By doing this, the projection 17 of the lower container 1 locks the container body 3 of the upper container 1 so that the upper container 1 does not fall from the lower container 1. It is locked to.

  As shown in FIGS. 5 and 6, the first side wall portion 13 of the lid 4 is formed so as to project downward from the edge portion of the top plate portion 12 so as to surround the periphery of the top plate portion 12. By providing the first side wall 13 on the lid 4, the inner surface of the lid 4 includes a recess having a predetermined depth. In this case, the concave portion has a housing space of the optical element 2 in the lid 4 and is constituted by the first side wall portion 13 and the top plate portion 12 which is the bottom surface thereof.

  The first flange portion 14 of the lid 4 is configured to surround the edge of the first side wall portion 13, and is configured in a flat plate shape substantially parallel to the top plate portion 12. The first flange portion 14 is configured to face the first flange portion 8 of the container body 3 when the lid 4 is placed on the container body 3.

  The compression pack 5 is made of, for example, a transparent resin bag. By the suction device, the air in the compression pack 5 is contracted by being sucked, and thereby, the container main body 3 and the lid 4 housed inside can be compressed. The compression pack 5 is sealed after the internal air is sucked.

  Hereinafter, the method to pack the optical element 2 using the container 1 of the said structure is demonstrated.

  First, the rectangular optical element 2 formed in a predetermined size (area) is sequentially accommodated in the container body 3 (first process or accommodation process). At this time, the optical element 2 housed in the housing portion 6 of the container main body 3 is erected by fitting the side portion thereof into the groove portion 6 c of the housing portion 6, and the upper end portion 2 a is from the base 7 of the container main body 3 Also, it is in the state of projecting upward (exposure).

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

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

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

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

  Finally, as shown in FIG. 8, in the container 1, the first flange portion 14 of the lid 4 contacts the first flange portion 8 of the container body 3, and the second side wall portion 15 of the lid 4 is the container The second flange portion 16 of the lid 4 is in contact with the second flange portion 10 of the container main body 3 in contact with the side wall portion 9 of the base 7 in the main body 3.

  The top plate portion 12 of the lid 4 deforms in a convex shape in a state of being in contact with the upper end portion 2 a of the optical element 2 housed in the container main body 3, but the amount of deformation is the first flange of the lid 4 It continues to increase until the portion 14 contacts the first flange portion 8 of the container body 3. When the first flange portion 14 of the lid 4 contacts the first flange portion 8 of the container main 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 of the top plate 12 stops, and at that time, the state in which the top plate 12 is deformed in a convex shape is maintained. At this time, the top plate portion 12 of the lid 4 is deformed in a convex shape to generate tension, and the tension causes all the optical elements 2 to be pressed.

  While the lid 4 presses the upper end portions 2a of all the optical elements 2 housed in the container main body 3 by such pressing of the top plate portion 12, the lid 4 fixes all these optical elements 2 in the housing position It will be done.

  According to the container 1 and the packing method according to the present embodiment described above, the optical element 2 is housed in the housing portion 6 of the container main body 3, the lid 4 is covered on the container main body 3, and these are housed in the compression pack 5 By compression and compression, the top plate portion 12 of the lid 4 can be deformed in a convex shape while being in contact with the upper end portions 2 a 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.

  Further, when the first flange portion 14 of the lid 4 comes into contact with the first flange portion 8 of the container main body 3, the increase in deformation of the top plate portion 12 stops, and at this time, the top plate portion 12 becomes convex. The deformed state is maintained. As described above, when the first flange portion 14 of the lid 4 and the first flange portion 8 of the container main body 3 contact each other, the degree of deformation of the top plate portion 12 can be regulated. That is, each of the first flange portions 8 and 14 functions as a restricting portion that restricts the degree of deformation of the top plate 12 (hereinafter, common symbols 8 and 14 are used for each flange portion and the restricting portion).

  Thus, by regulating the degree of deformation of the top plate 12 by the regulating portions 8 and 14, the top plate 12 presses the optical element 2 with an excessive force, or the pressing by the top plate 12 It is possible to avoid the situation that becomes insufficient. Thereby, the container 1 can stably and preferably fix the optical element 2 with an appropriate tension. In addition, 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 4 from being deformed too much and largely deviating from the original shape. Even when stacked vertically, these do not break the balance.

  In addition, when the compression pack 5 is unsealed when taking out the optical element 2, the top plate portion 12 which has been deformed in a convex shape is restored to the original flat plate shape, and the first flange portion 14 of the lid 4 The first flange portion 8 of the container body 3 is separated, and similarly, the second flange portion 16 of the lid 4 is also separated from the second flange portion 10 of the container body 3. As a result, a gap is generated between the second flange portion 16 of the lid 4 and the second flange portion 10 of the container main body 3 so that the lid 4 can be easily removed from the container main body 3. As a result, it is possible to efficiently carry out the work of taking out the optical element 2 after opening at the shipping destination.

  FIG. 9 shows a second embodiment of a container according to the present invention.
