Description

  The present invention relates to a patterned container provided with a special watermark pattern.

A compact container, a lipstick container, and the like that contain cosmetics are required not only to have functionality but also to have a good design and a design that reflects the product image. For this reason, various techniques for decorating cosmetic containers have been proposed. For example, a technique for integrating a decorative film on a lid of a compact container without using an adhesive is disclosed (see Patent Document 1).
JP 2001-292828 A

  However, the one using the decorative film has a problem that the decorative film part changes in quality or wears / damages over time, resulting in poor appearance. Moreover, since it is only a thing which affixed the planar film, even if it attaches a pattern to a film, there exists a problem that there is no depth in a pattern and is not interesting. In addition, it is conceivable to use a transfer foil with a certain pattern as the decorative film, but in order to obtain a transfer foil with a fine pattern, advanced technology is required, and the processing process becomes complicated and the cost increases. In addition to the above factors, the production lot is restricted.

  The present invention has been made in view of such circumstances, is provided with a beautiful three-dimensional watermark pattern, and even if the pattern is fine, the problem of cost increase and production lot restrictions do not occur. The purpose is to provide a container with a patterned pattern.

In order to achieve the above object, the present invention is a container in which at least a part of a portion appearing on the surface of a container is composed of a transparent member in which a non-transparent or translucent thin film layer is formed on the front surface or the back surface. The thin film layer forming surface of the transparent member is provided with the following uneven pattern A integrally with the thin film layer, and the concave or convex thin film layer of the uneven pattern A is removed by laser irradiation, A patterned container in which the removal unit is a watermark is defined as a first gist.
(A) A concavo-convex pattern formed by mold transfer, and each concave portion is constituted by at least one of a pyramidal shape and a truncated pyramid shape having a concave opening as a bottom surface.

Further, the present invention is a container composed of a transparent member in which at least a part of the portion appearing on the front surface of the container is formed with a non-transparent or translucent thin film layer on the front surface or the back surface, and the thin film of the transparent member The following concave / convex pattern A is provided on the surface opposite to the layer forming surface, and the thin film layer corresponding to the concave portion or convex portion of the concave / convex pattern A is removed by laser irradiation, and the removed portion becomes a watermark pattern. The patterned container is the second gist.
(A) A concavo-convex pattern formed by mold transfer, and each concave portion is constituted by at least one of a pyramidal shape and a truncated pyramid shape having a concave opening as a bottom surface.

Furthermore, the present invention includes a colored layer formed directly on the back surface of the transparent member or on a different surface facing the back surface of the transparent member. A patterned container in which the color can be seen through is defined as a third gist.

Further, the present invention is its inter alia, in particular, the upper Symbol wearing color layer, a fourth aspect of the textured container formed by the hologram foil.

That is, the patterned container of the present invention is configured by a transparent member in which at least a part (for example, a lid) of a part appearing on the front of the container is formed with a non-transparent or translucent thin film layer on the front surface or the back surface. The thin film layer forming surface or the opposite surface is provided with a special concave / convex pattern formed by mold transfer , and the concave / convex pattern is formed integrally with the thin film layer on the thin film layer forming surface. If the concave / convex pattern or concave thin film layer is removed by laser irradiation and the concave / convex pattern is formed on the surface opposite to the thin film layer forming surface, the concave / convex pattern concave / convex pattern is formed. Alternatively, the thin film layer facing the convex portion is removed by laser irradiation, and the removed portion has a watermark pattern. According to this structure, the said watermark pattern is comprised by the recessed part or convex part of the uneven | corrugated pattern provided to the transparent member, and can give a three-dimensional impression.

  The watermark pattern is formed directly by a combination of a thin film layer and an uneven pattern integrally formed on one side of the transparent member without using a decorative film or a transfer foil. Will not be worn, damaged or peeled off. In addition, the uneven pattern can be easily applied by in-mold molding or the like, and since it is easy to add fine unevenness, no matter how fine the pattern is set, the cost increases and the manufacturing It has the advantage of being less likely to lead to lot constraints.

  Moreover, since one side of the transparent member of the container is covered with a thin film layer such as a metal foil except for the watermark pattern portion, a relatively high strength can be obtained even if the thickness of the transparent member is set thin, This part can be made into a thin and compact design.

Furthermore, textured container of the present invention, particularly, since each concave portion constituting the concavo-convex pattern imparted to the transparent member is constituted by at least one of a pyramid shape and a truncated pyramid shape that a recess opening and a bottom, will be transparent tapered surfaces in the recesses are formed a large number by changing the angle, in the watermark pattern obtained by the thin film layer is removed, a variety reflection of light is seen, it becomes rich in interest.

  In the present invention, in particular, a colored layer is formed directly on the back surface of the transparent member or on a different surface facing the back surface, and the color of the colored layer can be seen through the transparent portion of the watermark pattern. The patterned container is more interesting because the watermark pattern appears as a three-dimensional color pattern along with various light reflections due to unevenness.

  And in the present invention, since the colored layer is formed of a hologram foil, the three-dimensional color pattern by the colored layer becomes a complex color pattern whose color changes to rainbow colors depending on the viewing angle. It will be even more interesting.

  Next, the best mode for carrying out the present invention will be described.

  FIG. 1 is a perspective view of a compact container that is the best mode for carrying out the present invention, and FIG. 2 is a sectional view taken along line XX ′. In these drawings, reference numeral 1 denotes a main body portion, and a cosmetic material such as a foundation is accommodated and held in a concave portion 2 provided on the left side toward the inside thereof. Further, a puff for applying cosmetics to the skin is accommodated and held in the recess 3 provided on the right side.

  Furthermore, as shown in FIG. 4 which is an exploded perspective view, the lid body 4 that covers the upper opening of the main body 1 has a lid frame body 6, a hologram foil 7 adhered to the entire upper surface, It is comprised with the cover plate 8 joined and integrated on the upper surface of the lid frame 6 to which the hologram foil 7 was stuck.

  A hinge portion 6a protrudes downward from the rear end portion of the lid frame 6, and the hinge portion 6a engages the rear end portion of the main body portion 1 so that it is indicated by a chain line in FIG. In addition, the lid 4 opens upward. A mirror 5 is attached to the inner side surface of the lid frame 6 (see FIG. 2).

  Moreover, the said cover plate 8 is comprised with the transparent member which consists of a transparent acrylic resin molded object, and the aluminum thin film layer 9 is formed in the back surface. The surface on which the aluminum thin film layer 9 is formed is provided with a concavo-convex pattern that is a combination of a large hexagonal frustum-shaped concave portion and a large hexagonal pyramid-shaped concave portion. Among them, the aluminum thin film layer 9 in the relatively large regular hexagonal frustum-shaped recess is removed, and the watermark pattern P is formed by making the inside of the recess transparent.

  The watermark pattern P can be obtained as follows, for example. That is, first, a mold for shaping the cover plate 8 is prepared. The surface of the mold on the side where the back surface of the lid plate 8 is shaped is also provided with a concavo-convex portion for transferring a concavo-convex pattern made up of large and small regular hexagonal truncated cone-shaped recesses and regular hexagonal pyramid-shaped recesses. ing. Then, the mold is closed by placing the aluminum foil transfer sheet on the side of the mold on which the back surface of the cover plate 8 is shaped, and molding is performed by injecting a resin material (in-mold molding). . Thereby, as shown to Fig.3 (a), integration of the aluminum thin film layer 9 to the back surface side of the cover plate 8, and shaping of the cover plate 8 to which the uneven | corrugated pattern was provided can be performed simultaneously. However, in this state, the entire back surface of the cover plate 8 provided with the uneven pattern is covered with the aluminum thin film layer 9.

  Therefore, as shown in FIG. 3 (b), among the aluminum thin film layer 9 in the concave pattern, in the concave part to be the watermark pattern P (in this example, a relatively hexagonal frustum shape constituting the concave and convex pattern is relatively The aluminum thin film layer 9 in the large concave portion is vaporized and removed by laser irradiation. As a result, the inside of the specific recess becomes transparent, and the watermark pattern P is formed on the lid plate 8.

  For the laser irradiation, an Nd: YAG laser or the like conventionally used for metal processing or the like can be used. And the processing method and processing conditions which remove thin film layers, such as the said aluminum thin film layer 9, can be suitably selected according to the laser apparatus to be used, the kind of metal thin film, etc. Further, in the laser irradiation, the recess position data of the portion to be removed can be easily obtained by using the mold data for forming the recess pattern, and based on this, the operation control of the laser irradiation can be performed. it can.

  An enlarged view of the watermark pattern P of the cover plate 8 obtained in this way is shown in FIG. In this watermark pattern, a concave / convex pattern made up of large and small regular hexagonal frustum-shaped concave portions provided from the back side of the cover plate 8 is a pattern in which flowers are arranged, and a transparent bottom surface in each concave portion The six transparent side surfaces with a taper are reflecting surfaces that reflect light in different directions. In addition, even in a recess where the aluminum thin film layer 9 is not removed (in this figure, a small regular hexagonal pyramid-shaped recess), the six side surfaces of the regular hexagonal pyramid are glossy reflecting surfaces by the aluminum thin film layer 9 covering the inside of the recess from the back side. It has become.

  The lid plate 8 on which the watermark pattern P is formed is joined and integrated with the lid frame body 6 on which the hologram foil 7 is adhered. The bonding is performed by applying an adhesive on the upper surface of the hologram foil 7 or the back surface of the cover plate 8 so as not to overlap the watermark pattern P, or using an adhesive tape or the like. Of course, both of them may be joined and integrated by providing engaging portions and engaging each other.

  According to this configuration, since the underlying hologram foil 7 can be seen through the watermark pattern P of the cover plate 8, the bottom and side surfaces of each recess of the watermark pattern P shine in different rainbow colors depending on the viewing angle. It becomes a very three-dimensional and beautiful pattern. Further, the concave portion covered with the aluminum thin film layer 9 also has a very three-dimensional glossy pattern due to the reflective surface in the glossy concave portion.

  The rainbow watermark pattern P and the glossy pattern are formed from the back side of the transparent cover plate 8, and the surface itself of the cover plate 8 maintains its original smoothness. Will not be worn, damaged or soiled over time. In addition, the concave pattern that is the basis of the watermark pattern P can be easily applied by in-mold molding, and it is easy to give a fine shape. However, there is an advantage that it is difficult to lead to a large cost increase and a restriction on a production lot.

  Further, the back surface of the cover plate 8 is covered with an aluminum thin film layer 9 except for the portion where the watermark pattern P is formed, and further joined and integrated with the cover frame body 6 to which the hologram foil 7 is adhered. Therefore, even if the thickness of each of these members is set to be relatively thin, the lid 4 as a whole can have high strength, and this portion can be made thin and compact.

  In the above example, the transparent member constituting the cover plate 8 may be any transparent member as long as it is conventionally used for molded products such as containers. Examples thereof include polystyrene, ABS resin, and polycarbonate. These must be transparent in order to show the watermark P, but need not be colorless, and even if they are slightly colored, there is no problem as long as the opposite side can be seen through.

  The aluminum thin film layer 9 integrally formed on the back surface of the cover plate 8 is vapor-deposited, sputtered, plated, hot stamped on the back surface of the cover plate 8 on which a concavo-convex pattern has been formed in addition to in-mold molding. For example, the aluminum thin film layer 9 can be formed integrally with the uneven pattern.

  Furthermore, the thin film layer formed on the back surface of the cover plate 8 is not limited to aluminum but may be stainless steel or the like. Furthermore, you may use the coating layer and resin film of non-transparent or translucent resin other than a metal. However, it is preferable to use a metal thin film from the viewpoint of maintaining strength and surface smoothness. In the present invention, the term “non-transparent or translucent” refers to a difference in the appearance of the removed portion and the non-removed portion of the thin film layer when the thin film layer is partially removed by laser irradiation. The thin film layer is not transparent as much as possible.

In the above example, the shape of each concave portion constituting the concavo-convex pattern is a regular hexagonal pyramid shape or a regular hexagonal truncated pyramid shape. It takes into account that the three-dimensional impression becomes more complex. Thus, polygonal conical shape or, Ru preferably der be a polygonal frustum shape. The watermark pattern P was formed by removing the aluminum thin film layer 9 in a specific recess (a relatively large regular hexagonal frustum-shaped recess in the above example) among the recesses, but the entire recess was changed to the watermark pattern P. It is arbitrary whether to select a specific concave portion to make the watermark pattern P.

  In the above example, the hologram foil 7 is attached to the lower surface (the upper surface of the lid frame body 6) that can be seen through the watermark pattern P so that it can be seen from the watermark pattern P. Even if the hologram foil 7 is simply sandwiched between the lid frame 6 and the lid plate 8, there is no problem. Alternatively, the hologram foil 7 may be directly attached to the back side of the cover plate 8 on which the aluminum thin film layer 9 is formed. In this case, it is not necessary to divide the lid body 4 into two members, that is, the lid frame body 6 and the lid plate 8, and a single member can be obtained.

  The same effect can be obtained by using a glossy sheet whose color tone changes depending on the viewing angle, such as an aurora tone sheet or an opal tone sheet, instead of the hologram foil 7. Furthermore, instead of these glossy sheets, simple colored sheets may be used. In that case, since the light reflection effect on the watermark pattern P is weak, a strong impression like a glossy sheet cannot be obtained, but the watermark pattern P still has a certain effect that it looks three-dimensional with the color of the colored sheet. Obtainable. In addition, it may replace with sticking the said colored sheet | seat and may make it form a colored layer by applying a colored coating material. Alternatively, without using the hologram foil 7 or a colored sheet or forming a colored layer or the like, the watermark pattern P can show the color of the member itself below or the color of the contents contained in the container. There is no problem.

  In the case of using the hologram foil 7 or the colored sheet, they may be opposed to each other with a certain space, instead of directly contacting the back surface side of the cover plate 8. For example, as shown in FIG. 6, in the same manner as in the above example, in a compact container or the like having a lid 4 ′ on which a watermark pattern P is formed and an inner lid 10, the hologram foil is placed on the inner lid 10. The same effect as in the above example can be obtained simply by sandwiching 7 or a colored sheet. Further, as shown in FIG. 7, the hologram foil 7 or a colored sheet may be directly attached to the upper surface of the inner lid 10 or a colored layer may be formed.

  Further, in the above example, the concave and convex pattern is formed integrally with the aluminum thin film layer 9 on the back surface side of the cover plate 8, and then the aluminum thin film layer 9 in the concave portion of the concave and convex pattern is removed to form the watermark pattern P. (Refer to FIG. 3) The form of the watermark pattern P is not limited to this example. For example, as in FIG. 3A, an uneven pattern is provided integrally with the aluminum thin film layer 9 on the back surface side of the cover plate 8, and then the aluminum thin film layer 9 in the concave portion is left and the aluminum thin film layer 9 on the convex portion side is left. As shown in FIG. 8, among the concavo-convex patterns provided on the cover plate 8, a pattern in which the convex portion side is a watermark pattern P can be obtained. Also in this case, it is arbitrary whether to remove the aluminum thin film layer 9 of all the convex portions or select a specific convex portion and remove the aluminum thin film layer 9 (the same applies to the following examples).

  Alternatively, as shown in FIG. 9, the concave / convex pattern integrated with the aluminum thin film layer 9 is not provided on the back surface side of the cover plate 8 but on the front surface side of the cover plate 8. After applying the pattern, as shown in FIG. 10 (a), the aluminum thin film layer 9 in the concave portion is removed to form a watermark pattern P, or as shown in FIG. 10 (b), the convex portion side The watermark pattern P can be formed by removing the aluminum thin film layer 9.

  Further, in the present invention, for example, as shown in FIG. 11, the front surface side of the cover plate 8 is covered with an aluminum thin film layer 9, and a concavo-convex pattern is provided on the back surface side. Then, as shown in FIG. Of the concavo-convex pattern on the side, the portion of the aluminum thin film layer 9 on the surface side facing the concave portion 10 is removed to form the watermark pattern P, or as shown in FIG. The watermark pattern P can be formed by removing the portion of the aluminum thin film layer 9 on the surface side facing the convex portion 11.

  Furthermore, conversely to the above example, as shown in FIG. 13, for example, the back surface side of the cover plate 8 is covered with the aluminum thin film layer 9, and a concavo-convex pattern is given to the front surface side, and then shown in FIG. 14 (a). As shown in FIG. 5B, the watermark pattern P is formed by removing the portion of the aluminum thin film layer 9 on the back side facing the concave portion 10 ′ from the concavo-convex pattern on the front side. The watermark pattern P can be formed by removing the portion of the aluminum thin film layer 9 on the back side facing the convex portion 11 ′.

  In these examples, the present invention is applied to a compact container, but the type and shape of the container are not limited thereto.
