JP5564826B2 - Sleeve case-shaped packaging container with microlenses - Google Patents

Description

  The present invention relates to a packaging container with a microlens in which a microlens sheet is bonded to the surface of the packaging container.

  As a conventional packaging container with a microlens, a flat plastic microlens sheet (for example, a lenticular screen sheet) and a printing pixel sheet (for example, a stereoscopic printing pixel sheet) for optical viewing by the microlens are provided. There is a packaging container with a microlens in which an optical image sheet (for example, a three-dimensional printing sheet) formed by matching the lens pitch and the pixel pitch and pasting them together is adhered to the surface of a packaging container such as a paper box with an adhesive.

  In addition, there is a packaging container with a microlens formed by bonding a flat plastic lenticular screen sheet (microlens sheet) to a stereoscopic printing pixel surface printed directly on the surface of a packaging container such as a paper box. . Moreover, as a packaging material and packaging container which performed various printing on the base-material surface of the packaging material, and improved the designability, there exist patent document 1, 2, etc., for example.

  And a lenticular screen sheet and cubic lens sheet (micro convex lens array sheet) for generating a visual three-dimensional effect, or a linear Fresnel lens array sheet and a rotary Fresnel lens array sheet for generating a visual magnification effect, etc. Various visual expression methods such as a three-dimensional effect and a magnification effect using a microlens sheet have been proposed.

  Various methods for visual expression using a microlens sheet such as a lenticular screen have been proposed. These basic configurations have a transparent layer (transparent substrate) on the design layer (pixel layer) that generates the visual effect (enlarged image, stereoscopic image, etc.) applied to the packaging material substrate surface. A microlens sheet having a lens layer (lens array) formed thereon by a hot press molding method or a printing method is covered.

  Usually, it is desirable that the distance between the pixel layer on the base material surface for generating a visual effect and the transparent layer of the microlens sheet is constant according to the focal length of the lens layer of the microlens sheet. .

  In addition, the microlens sheet used for attaching to such a packaging container with a microlens has no trouble in the packaging function of the container body and the manufacturing process using the blank sheet, and the packaging container blank. In order to be flexible and easy to bend as a film used for the sheet, it is necessary to use a relatively thin sheet or film.

  In order to generate a visual effect on the surface of a packaging container such as a paper box, when a microlens array and a transparent substrate are arranged on the pixel layer applied to the surface of the packaging container base material (packaging material), As the transparent substrate, a microlens configuration such as a transparent sleeve case in which a lens array is arranged on the outer surface on which a container such as a paper box can be loaded can be considered.

In the case of a sleeve case, the sleeve case and the container do not completely adhere to each other, and a slight gap is generated between the container and the sleeve case, particularly at the center of the container. The distance between the pixel layer on the surface and the lens array of the sleeve case varies,
There was a drawback that the visual effects such as the expansion effect and three-dimensional effect of the micro lens would change.

  An object of the present invention is to provide a certain distance between a microlens and a pixel (pattern) by providing irregularities on an arbitrary part of a packaging container base material on which a visual expression pattern is printed by pressing or hot pressing. The goal is to keep it at a distance.

The invention according to claim 1 of the present invention includes a pair of convex ridges 2 that are spaced apart from each other on the surface of the structure base layer 1 of a sleeve case-shaped packaging container, or a U-shape or an annular shape in a pattern. with each of Totsutsutsumi 2 that surrounds the said structural groups to comprise a pixel layer 3 for generating visual effects on the inside of Totsutsutsumi 2 of the respective people, bridging the Totsutsutsumi 2 and the pixel layer 3 of each of s microlens sheeting 4 in timber 1 Men及 beauty Totsutsutsumi two faces, by a gap portion between the pixel layer 3 and the micro lens sheet 4 (air layer) 7 is formed, coated is mounted at a predetermined distance A sleeve case-shaped packaging container with a microlens.

The invention according to claim 2 of the present invention is a pixel having a concave portion 8 having a desired area on the surface of the structural base material layer 1 of the sleeve case-shaped packaging container, and generating a visual effect inside the concave portion 8. The microlens sheet 4 is provided on the surface of the structure base 1 so as to bridge the concave portion 8 and the pixel layer 3, and a gap portion (air layer) 7 between the pixel layer 3 and the microlens sheet 4. Is formed into a sleeve case-shaped packaging container with a microlens, which is covered with a predetermined interval.

According to the present invention, the substrate surface of the packaging container provided with a pixel layer for generating a visual expression effect such as three-dimensional or enlargement for an image, a pattern, a color tone, or the like is lifted or lifted by pressing or the like. because we have mutually spaced opposing pair of each Totsutsutsumi, or to form a Totsutsutsumi portion or concave portion of each surrounding in a pattern shape or circular-shape, subjected to a pixel layer on the inside, the packaging A gap is formed between the transparent base material layer surface constituting the microlens sheet mounted on the surface of the container and the pixel layer on the surface of the packaging container, and the lens focal length is kept constant by placing the gap. Can do.

The microlens sheeting to be coated superimposed pixel layer formed on the packaging container, the Totsutsutsumi portion or concave portion of each formed on the surface of the packaging container base, be kept constant intervals with a gap portion Therefore, even when the thickness of the lens array layer or the transparent substrate layer of the microlens sheet is thin, a gap (air layer) is formed between the microlens sheet and the pixel layer, so that the thickness is relatively thin. The lens focal length between the pixel layer and the microlens sheet can be set appropriately. In addition, even when the microlens sheet mounted on the surface of the packaging container is gently curved, the microlens sheet can maintain a more stable focal length with respect to the pixel layer, thereby generating a lens visual effect. It becomes possible.

According to the present invention, when the microlens sheet to be mounted on the packaging container is in the shape of a sleeve case, the inner surface of the sleeve case (microlens sheet) and the pixel layer on the surface of the container that faces the sleeve case have a constant height. It is possible to maintain a constant distance by placing a gap portion (air layer) with good contact through the protruding ridge portion and the recessed portion. Therefore, not only at the end of the packaging container but also at the center, the microlens sheet and the packaging container are in close contact with each other through the convex ridge part and the recessed part, and therefore, at the center and outside of the packaging container, the lens array layer, At the same distance between the pixel layer facing to the container surface does not vary, via the Totsutsutsumi portion or concave portion of each of the predetermined height can be held constant distance, visual, etc. steric effect and expanding effect of the microlens sheeting effect Will not be damaged.
