Description

tray

The present invention relates to a tray on which a sheet provided with a paste-like photocurable layer can be placed.

Conventionally, regarding the packaging of a sheet having ultraviolet curability, a packaging body that is stored in an aluminum packaging body is known (see, for example, Non-Patent Document 1). This sheet is used for repairing resin parts and the like. By wrapping the sheet in an aluminum package, UV rays are blocked and the sheet is prevented from hardening. It also shuts off the outside air and prevents the sheet from drying out.

However, a package as in Non-Patent Document 1 cannot be used for a sheet having a paste-like photocurable layer. This is because the photo-curing layer comes into contact with the package or the like, and the surface roughness of the surface of the photo-curing layer is deteriorated.

The present invention has been made in view of the above-mentioned problems, and provides a tray capable of maintaining good surface roughness of the surface of the paste-like photocurable layer in the use, transportation, storage, etc. of the sheet. The purpose is to do.

In order to achieve the above object, the tray according to the present invention is for a sheet on which a sheet provided with a paste-like photocurable layer containing a photocurable resin is placed on one surface of a sheet-like base material. A tray, a contact blocking portion that prevents the photo-curing layer from coming into contact with the tray, and a positioning portion that positions the sheet on the tray are formed.

According to the present invention, the paste-like photocurable layer formed on the sheet is positioned in a non-contact state by the contact blocking portion and the positioning portion formed on the tray. Therefore, the surface roughness of the surface of the photocurable layer can be maintained in a good state.

<First Embodiment>
1 to 4 are views showing the first embodiment of the present invention.

As shown in FIG. 1, a plurality of sheets 9 are placed on the tray 1. In the present embodiment, a state in which a total of eight sheets 9 of 2 rows × 4 sheets are placed is shown.
[Sheet]

As shown in FIG. 3, the sheet 9 has a sheet-like base material 91 and a paste-like photocurable layer 92 on the lower surface 911 of the base material 91. The photo-curing layer 92 is formed inside the edge 912 of the base material 91. The shapes of the base material 91 and the photo-curing layer 92 are rectangular in a plan view, but are not limited thereto.

The sheet 9 forms a latent image of a pattern by irradiating a paste-like photohard layer with light. The sizes of the sheet and the photo-curing layer are appropriately set according to the size of the pattern to be formed.

The material of the base material 91 can be selected according to the purpose. If a material having high light transmission is used for the sheet 9, it is possible to irradiate light from the base material 91 side, and in that case, glass, polyolefin (PO) such as poly-4-methylpentene-1, etc. can be used. Can be mentioned.

Further, when a flexible substrate or the like is produced by using a material having an insulating property for the sheet 9, polyester such as polyethylene terephthalate (PET), liquid crystal polymer (LCP) and the like can be mentioned. In this case, the light is applied to the photocurable layer 92 side.

The photocurable layer 92 contains a photocurable resin. The photocurable resin is a component that polymerizes with each other by light (active energy ray) such as ultraviolet rays, electron beams, and gamma rays.

The photo-curing layer 92 may further contain a conductive material. As the conductive material, for example, silver, copper and the like are used, but the conductive material is not limited thereto. By including the conductive material, the pattern formed on the photocurable layer 92 can be a conductive pattern (circuit pattern).

Since the photo-curing layer 92 is in the form of a paste, it can adhere to or adhere to the surface of an object forming a pattern.

As shown in FIG. 2, the base material 91 has three positioning holes 93. These three positioning holes 93 are arranged at equal intervals in the lateral direction. The number of positioning holes 93 is not limited to this. Further, in the present embodiment, the shape of the positioning hole 93 is circular, but the shape is not limited to this.
[tray]

The tray 1 is made of a material having the property of being impermeable to ultraviolet rays. The "ultraviolet impervious" means a property that can block ultraviolet rays having a wavelength of 405 nm. This makes it possible to prevent ultraviolet rays from being incident on the tray 1.

Examples of the method of imparting the property of impermeable to ultraviolet rays to the tray 1 include a method of mixing an ultraviolet absorber (for example, a black pigment) and a method of depositing a metal thin film.

The ultraviolet transmittance of the tray 1 is preferably 0 to 10% and more preferably 0 to 5% at a wavelength of 405 nm.

It is also desirable that the tray 1 has antistatic properties. This makes it possible to prevent dust and dirt from adhering due to static electricity.

Further, the thickness (thickness) T1 of the tray 1 can be set to 0.8 to 1.5 mm according to the application, but is not limited to this. The thickness T1 may be appropriately set within a range in which impact resistance against dropping, vibration, etc. during transportation or the like is sufficiently secured.

Further, the tray 1 is manufactured by vacuum forming a thermoplastic resin. The material of the tray 1 is preferably composed of a non-foaming material such as an olefin resin such as polypropylene (PP).

As shown in FIG. 1, the tray 1 has a plurality of positioning portions 2 formed by the protruding portions 21, recesses 3, and a plurality of finger insertion portions 4, respectively.

FIG. 2 is an enlarged view of the area [A] shown in FIG. 1, and is a plan view showing a state in which the sheet 9 is placed and positioned on the tray 1. Three positioning portions 2, one recess 3, and four finger insertion portions 4 correspond to each sheet. When the sheet 9 is placed, the entire recess 3 and a part of the four finger insertion portions 4 are covered with the base material 91 in a plan view.

As shown in FIG. 3, the positioning unit 2 is composed of a columnar projecting portion 21 projecting upward. The protrusions 21 are arranged at equal intervals in the lateral direction, and the sheet 9 is positioned by inserting the protrusions 21 into the positioning holes 93 of the corresponding base material 91.

Since the outer diameter φD21 of the root portion of the protruding portion 21 is set smaller than the inner diameter φD93 of the positioning hole 93 of the base material 91, the sheet 9 can be easily inserted.

The outer shape of the protruding portion 21 is cylindrical, but the outer shape is not limited to this. Further, the outer diameter of the protruding portion 21 gradually decreases upward, but the outer diameter is not limited to this.

Further, since the protruding amount H21 of the protruding portion 21 is sufficiently larger than the thickness T91 of the base material 91 of the sheet 9, the sheet 9 is prevented from falling off from the tray 1.

The number of protrusions 21 and positioning holes 93 may be at least two so that the sheet 9 does not rotate in the tray 1, but the number is not limited.

As shown in FIG. 3, the recess 3 is formed in a concave shape downward. Further, the recess 3 is formed by a flat plate-shaped bottom portion 31 and a side wall portion 32 surrounding the periphery of the bottom portion 31, and the side wall portion 32 has a tapered shape inclined in a direction extending upward with respect to the bottom portion 31. .. The recess 3 is set sufficiently larger than the area of the photocurable layer 92.

When the sheet 9 is placed on the tray 1, the base material 91 is on the upper side and the photocurable layer 92 is on the lower side. By doing so, the photo-curing layer 92 is located inside the recess 3. Further, the bottom portion 31 of the recess 3 is sufficiently separated from the photo-curing layer 92, and the side wall portion 32 is also sufficiently separated from the photo-curing layer 92. Since the base material 91 placed on the tray 1 is positioned, the sheet 9 does not move in the horizontal direction. In this way, the photocurable layer 92 is prevented from coming into contact with the tray 1. That is, the recess 3 is a contact blocking portion 6 with respect to the photocurable layer 92.

The finger insertion portion 4 is for removing the sheet 9 placed on the tray 1 with a finger FN. As shown in FIGS. 2 and 4, two finger insertion portions 4 are formed vertically so as to sandwich the concave portion 3, and are arranged at positions where the edge portion 912 of the base material 91 can be grasped by the finger FN. ..

As shown in FIG. 4, the finger insertion portion 4 is formed in a concave shape downward. Further, the finger insertion portion 4 is formed by a flat plate-shaped bottom portion 41 and a side wall portion 42 surrounding the periphery of the bottom portion 41, and the side wall portion 42 has a tapered shape inclined in a direction extending upward with respect to the bottom portion 41. ing.

The shape of the finger insertion portion 4 is not limited to the above shape as long as a finger can be inserted to remove the sheet 9. Hereinafter, the finger insertion portion located above the recess 3 is referred to as a “finger insertion portion 4A”, and the finger insertion portion located below is referred to as a “finger insertion portion 4B”.

The finger insertion part 4A and the finger insertion part 4B are arranged so as to be laterally separated from each other. In the present embodiment, the number of finger insertion portions 4 is 4, but the number is not limited to this.

Further, it is desirable that the depth DP4 of each finger insertion portion 4 and the depth DP3 of the recess 3 are set to the same depth.

<Second Embodiment>
The second embodiment of the present invention will be described with reference to FIGS. 5 to 16, but the differences from the above-described embodiments will be mainly described, and the same matters will be omitted.
In this embodiment, an embodiment in which a plurality of trays are stacked will be described.

A plurality of trays 1 can be stacked to form a tray set 10. 5 and 8 show a tray set 10 in which two trays 1 are stacked. In the following, the lower tray is referred to as "tray 1A" and the upper tray is referred to as "tray 1B".

In this embodiment, the tray 1A and the tray 1B have the same shape. The manufacturing cost is reduced by manufacturing with the same mold.

FIGS. 5, 6 and 7 show an embodiment when the sheet 9 is placed on the tray 1 to obtain the tray set 10.

As shown in FIG. 6, the recess 3, the finger insertion portion 4, and the positioning portion 2 formed in the tray 1 are not arranged point-symmetrically with respect to the center O1 of the tray 1. Therefore, when the tray 1B is inverted and overlapped in the horizontal direction with respect to the tray 1A, the respective portions are offset and overlapped in the vertical direction by the amount indicated by the solid line and the alternate long and short dash line.

As shown in FIG. 7, when the tray 1B is inverted and overlapped with respect to the tray 1A, the sheet 9 placed on the tray 1A is pressed by the flat plate-shaped bottom portion 31 of the recess 3 of the tray 1B in the vertical direction. It can be seen that it is fixed to. That is, if the trays 1B are inverted and used in an overlapping manner in this way, it is possible to prevent the sheet 9 from moving in the vertical direction.

An isosceles triangle marker 5 is attached to the front side of the tray 1. The marker 5 makes it easy to determine the orientation of each tray 1 when stacking a plurality of trays 1 while inverting them. The shape of the marker 5 is not limited.

On the other hand, FIGS. 8, 9, and 10 show an embodiment in which the tray set 10 is obtained without placing the sheet 9 on the tray 1.

As shown in FIG. 9, the tray 1B is stacked in the same direction with respect to the tray 1A. This form can be used for storage, transportation, etc. of an empty tray before or after placing the sheet 9.

As shown in FIG. 10, since the tray 1A and the tray 1B have the same shape, if the tray 1A and the tray 1B are stacked without being inverted, the recess 3 of the tray 1B slips into the recess 3 of the tray 1A. That is, the volume of the tray set 10 can be kept small. Therefore, it becomes easy to handle when storing, transporting, etc. the tray before or after use. Further, whether or not the sheet 9 is packed inside can be easily determined from the difference in the volume of the tray set 10.

Although the second embodiment has been described as an example of a case where the sheet 9 is manufactured with a common mold, the sheet 9 can be positioned on the tray while protecting the photocurable layer of the sheet 9, and the sheet 9 can be pressed from above. If it has a shape, a tray having a different shape may be adopted.
