An outer container 23 including a mounting cap portion 22 that covers the top surface of the container body 21, and a bag container as an inner container that is replaceably arranged inside the outer container 23. And a container having a double structure. The decorative sheet 10 is attached by an adhesive or a pressure-sensitive adhesive or the like so as to cover the outer peripheral surface of the cylindrical body portion 21a of the container body 21 having a bottomed cylindrical shape. The outer peripheral surface of the portion 21a is formed.

Further, in the present embodiment, the spout member 25 is integrally attached to the upper end portion of the bag container 24 which is the inner container, and the mounting cap portion 22 is provided with the guide sleeve portion 22a formed in the central portion thereof. The pump dispenser 30 is detachably mounted as a unit so as to penetrate therethrough. By tightening the male screw ridge 25a provided on the outer peripheral surface of the spout member 25 to the female screw ridge 22c of the screwing sleeve 22b provided so as to project downward from the lower surface of the mounting cap portion 22, The bag container 24 is attached to the mounting cap portion 22 in a state where the pump housing 31 and the suction cylinder portion 35 of the pump dispenser 30 are arranged inside the spout member 25 and the bag container 24. The mounting cap portion 22 has an outer diameter similar to the outer diameter of the tubular body portion 21a of the container body 21, projects downward from the outer peripheral edge portion, and is attached to the top end portion of the tubular body portion 21a of the container body 21. It has a peripheral edge locking portion 22d to be locked. By locking the peripheral edge locking portion 22d to the top end portion of the tubular body portion 21a of the container body 21, the bag container 24 is supported from the mounting cap portion 22 via the spout member 25 and the pump dispenser 30. And is held in a state of being hung inside the outer container 23.

Further, in the present embodiment, the pump dispenser 30 attached to the bag container 24 is a known discharge tool including a pump housing 31, a suction cylinder portion 35, a nozzle head (pressing operation portion) 36, and the like. The pump housing 31 of the pump dispenser 30 is configured to include therein a pump chamber (not shown), a ball valve (not shown), a biasing means (not shown) preferably by a spring, and the like. The pump dispenser 30 includes a nozzle head 36 having a lateral discharge passage 36a formed therein and functioning as a pressing operation unit. The pump dispenser 30 expands and contracts the pump chamber in the pump housing 31 by the action of the piston 37, which is integrally connected to the nozzle head 36 and has a vertical discharge passage 37a continuous with the horizontal discharge passage 36a therein. Thereby, the content liquid is sucked up from the bag container 24 and discharged from the tip end discharge port 36b of the nozzle head 36. As a result, the decorative container 20 is a discharge container with a pump for discharging the content liquid by the pump dispenser 30.

Then, in the present embodiment, the decorating sheet 10 that is attached to cover the outer peripheral surface of the tubular body portion 21a of the container body 21 to form the decorative container 20 is preferably injection compression molded as described above. Thus, the sheet-shaped base portion 11 and the three-dimensional decoration portion 12 are integrally molded, and the sheet-shaped base portion 11 and the three-dimensional decoration portion 12 are formed by using the same synthetic resin material. As shown in FIGS. 3 and 4, the sheet-like base portion 11 preferably has a bendable thickness t1 of 0.2 to 0.8 mm, and the three-dimensional decoration portion 12 preferably has a tip in the protruding direction. The portion 12a has a solid three-dimensional shape in which the height h1 from the front surface 11a of the sheet-shaped base portion 11 is equal to or higher than the thickness t1 of the sheet-shaped base portion 11.

Here, in the injection compression molding for integrally molding the sheet-shaped base portion 11 and the three-dimensional decoration portion 12, in this embodiment, as will be described later, a gate for supplying resin to the cavity is fixed (see FIG. )-(D)) except that it is provided in the central portion, it can be easily carried out by using a molding apparatus having the same configuration as the injection compression molding apparatus described in JP-A-61-211012. can do. The injection compression molding device is known as a device capable of accurately forming a precision component such as a plastic lens in a stable state, and performs molding while controlling the flow rate and pressure of the resin supplied to the cavity. It is like this. By forming the decorative sheet 10 using an injection compression molding device, a thin sheet-like base portion 11 having a thickness t1 of 0.2 to 0.8 mm, which is preferably bendable, is easily formed with high precision. In addition to the above, it is preferable that the height h1 from the front surface 11a of the sheet-shaped base portion 11 is a height equal to or greater than the thickness t1 of the sheet-shaped base portion 11 and that has a solid three-dimensional shape. It is possible to accurately form the three-dimensional decorative pattern of the portion 12 so as to have a desired shape. Further, as will be described later, it becomes possible to easily form a three-dimensional decorative pattern of the brilliant-like three-dimensional decorative portion 12 including an angular ridge, and at the same time, a light is applied to the back surface 11b of the sheet-shaped base portion 11. It becomes possible to easily form the hologram-like fine unevenness of the interval of 380 nm to 50 μm and the height difference capable of causing interference or total reflection. Here, the solid three-dimensional shape of the three-dimensional decoration unit 12 can be various three-dimensional shapes such as a columnar three-dimensional shape and a cone-shaped three-dimensional shape, and is a donut shape or a drop-shaped three-dimensional shape. You can also do it.

The same synthetic resin material for integrally molding the sheet-shaped base portion 11 and the three-dimensional decoration portion 12 is, for example, polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), acrylic resin (PMMA), ethylene ionomer, A synthetic resin material such as polycarbonate (PC) or polycycloolefin can be used. Further, synthetic resin materials of the same kind, for example, a synthetic resin material in which hard acrylic and soft acrylic are blended in a predetermined ratio can be used as the same synthetic resin material. Further, a polymer alloy made of a plurality of blendable synthetic resin materials can be used as the same synthetic resin material. As the polymer alloy, for example, PC (polycarbonate)/PS (polystyrene) alloy can be preferably used. Since the synthetic resin material for integrally molding the sheet-shaped base portion 11 and the three-dimensional decoration portion 12 is the same synthetic resin material, the recyclability is improved and the number of manufacturing steps is reduced, which simplifies the process. In addition, it is possible to obtain a seamless integrally molded product and increase the strength of the integrally molded product. In addition, the same synthetic resin material is preferably a transparent or translucent resin. Since the same synthetic resin material for integrally molding the sheet-shaped base portion 11 and the three-dimensional decoration portion 12 is a transparent or semitransparent resin, the three-dimensional decoration portion 12 particularly has a solid three-dimensional shape. Thus, it becomes possible to realize a three-dimensional expression with depth, and to realize a transparent color and a sense of brightness by using a high refractive index material (eg, acrylic resin). In addition, it is possible to add a variety of expressions and a sense of quality using diffuse reflection and interference of light. It is also possible to adjust the transparency and flexural elasticity according to the purpose of use.

The transparency of the resin can be evaluated by the haze value measured using a haze meter according to JIS K7136:2000 (ISO 14782:1999), and the haze value measured with a sample having a thickness of 1 mm is 50. % Or less is preferable.

In the present embodiment, the decorative sheet 10 has a sheet-shaped base 11 having a thickness t1 of preferably 0.2 to 0.8 mm. As a result, the decorative sheet 10 can be molded at high speed with a reduced amount of resin, and can be flexibly processed. From such a viewpoint, the thickness t1 of the sheet-shaped base portion 11 of the decorative sheet 10 is more preferably 0.2 to 0.7 mm, further preferably 0.3 to 0.6 mm.

In addition, in the present embodiment, the three-dimensional decoration portion 12 of the decorative sheet 10 preferably has a height h1 from the front surface 11a of the sheet-shaped base portion 11 of the projecting direction tip portion 12a that is the thickness of the sheet-shaped base portion 11. It has a height of t1 or more and has a solid three-dimensional shape. Here, the height h1 is the maximum height of each three-dimensional decoration portion 12. Since the height h1 of the protruding direction tip portion 12a of the three-dimensional decoration portion 12 is higher than the thickness t1 of the sheet-shaped base portion 11, the three-dimensional effect of the three-dimensional decoration portion 12 can be effectively emphasized. Will be possible. Since the three-dimensional decoration part 12 has a solid three-dimensional shape, it is possible to improve the brightness and the three-dimensional effect due to the reflection of light, and the decoration sheet 10 is preferably transparent or translucent. When it is made of a different synthetic resin material, it is possible to improve the transparency. From these viewpoints, the viewpoint of being able to emphasize the depth feeling, and the viewpoint of formability, the height h1 of the protruding direction tip portion 12a of the three-dimensional decoration portion 12 having a solid three-dimensional shape is 0.3 to 2 mm. The thickness is preferably 0.4 to 1.5 mm, more preferably 0.5 to 1 mm.

Further, from the same viewpoint, the ratio h1/t1 between the thickness t1 of the sheet-shaped base portion 11 and the height h1 of the protruding direction tip portion 12a of the three-dimensional decoration portion 12 from the front surface 11a of the sheet-shaped base portion 11 is It is preferably 1 or more and 10 or less, more preferably 1.1 or more and 5 or less, and further preferably 1.2 or more and 2.5 or less.

Here, each of the three-dimensional decorations 12 formed on the front surface 11a of the sheet-shaped base 11 may be one continuous three-dimensional decoration, and on the front surface 11a of the sheet-shaped base 11, It may be an assembly of a plurality of unit three-dimensional decoration portions 12b (see FIG. 3) provided in a separated state. When the three-dimensional decorating part 12 is an assembly of a plurality of unit three-dimensional decorating parts 12b, at least one unit three-dimensional decorating part 12b has a surface on the front side of the sheet-shaped base 11 of the tip end portion 12a in the protruding direction. It is preferable that the height h1 from 11a is not less than the thickness t1 of the sheet-shaped base portion 11. The height h1 of the projecting direction tip portion 12a may be lower than the thickness t1 of the sheet-shaped base portion 11 in the aggregate of the unit three-dimensional decoration portions 12b.

Further, in the present embodiment, it is preferable that the three-dimensional decorative pattern of the three-dimensional decorative portion 12 is formed so that at least a part thereof includes a sharp ridge line 12c having an angle (see FIG. 3). Thereby, for example, it becomes possible to express light by irregular reflection of a brilliant cut of a diamond tone, and it is possible to form more various uneven patterns. In addition, the three-dimensional decorative pattern of the three-dimensional decorative portion 12 is formed by mixing both a portion including a sharp ridge line 12c with a square shape and a portion that is rounded and curved to form an even more diverse uneven pattern. It becomes possible (see FIG. 3).

Furthermore, in the present embodiment, the back surface 11b of the sheet-shaped base portion 11 is preferably a flat surface. Since the back surface 11b of the sheet-shaped base portion 11 is a flat surface, the decorating sheet 10 is attached to the outer peripheral surface of the tubular body portion 21a of the container main body portion 21 via an adhesive or an adhesive. , And can be easily attached. It suffices that the flat surface is flat from a macro point of view. For example, the flat surface 11b on the back side of the sheet-shaped base portion 11 can cause light to interfere with the same wavelength of visible light (380 to 780 nm). ), and fine irregularities having a height difference may be formed. Further, for example, like a prism sheet described in Japanese Patent Application Laid-Open No. 7-174910, a prism array capable of totally reflecting light and having an apex angle of 80 to 150° and a pitch of about 50 μm may be formed. .. The flat surface 11b on the back side of the sheet-like base 11 is provided with fine irregularities of 380 nm to 50 μm intervals and height differences capable of causing interference or total reflection of light, thereby providing a hologram-like or metallic luster. It is possible to form a tonal pattern, and it is possible to form an uneven pattern of a variety of expressions. Fine irregularities capable of interfering or totally reflecting light are easily formed by a simple work process without laminating a hologram-like film by injection compression molding using the above-mentioned injection compression molding device. can do.

Further, in the present embodiment, a metallic or holographic film may be laminated on the back surface 11b of the sheet-shaped base 11 which is the flat surface of the decorative sheet 10. As a result, it becomes possible to form an uneven pattern of various expressions due to the metallic luster, and as in the case where fine unevenness is formed on the flat surface 11b on the back side of the sheet-like base 11 as described above, It is possible to form a concavo-convex pattern with a variety of hologram-like expressions that cause interference or total reflection.

Further, in the present embodiment, as shown in FIGS. 3 and 4, the through hole 40 is formed in the region of the sheet-shaped base portion 11 other than the portion where the three-dimensional decorative portion 12 projects. In the present embodiment, the through hole 40 preferably has a circular opening shape, and has an opening area of 0.2 to ⁴ cm ² , for example. Since the through hole 40 has a circular opening shape, processing for forming the through hole in the movable die 52 and the fixed die 51 (see FIGS. 5A to 5D) forming the cavity 54. As will be described later, without performing any step, in the step of compression-molding the decorative sheet 10, a gate cut is performed to close the gate 53, or a disc gate 55 (see FIG. 6) is punched as a gate. This makes it possible to easily form the circular through hole 40 in the sheet-shaped base 11. Since the through hole 40 has an opening area of 0.2 to 4 m ^{2, both} a sufficient resin flow rate at the time of molding and a good gate blocking property or a good punching property without distortion or burrs are compatible. Can be achieved.

Further, in the present embodiment, the through hole 40 is preferably formed in the central portion of the sheet-shaped base portion 11. Thereby, as will be described later, in the step of compression-molding the decorative sheet 10, a gate cut is performed to close the gate 53 (see FIG. 5C), or a gate such as a disc gate 55 (see FIG. 6) is used. When the circular through hole 40 is formed in the sheet-shaped base 11 by punching or the like, the gates 53 and 55 for supplying the synthetic resin material into the cavity 54 are necessarily in the central portion of the cavity 54. Will be placed. As a result, even when the rectangular sheet-shaped base 11 having a considerable size having an area of about 200 to 1000 cm ² is formed, the gate for supplying the synthetic resin material into the cavity is provided at the rectangular peripheral edge. It is possible to shorten the maximum flow length of the synthetic resin material for reaching the entire synthetic resin material from the gates 53, 55 in the central portion to the entire cavity 54 by about half as compared with the above. The synthetic resin material can be easily spread over the entire cavity 54 without any gaps, and the sheet-shaped base 11 has a good quality and a thin thickness of 0.2 to 0.8 mm, and has a relatively large area. The decorative sheet 10 can be easily formed by injection compression molding in a short production cycle.

In the present embodiment, the decorative sheet 10 in which the sheet-shaped base portion 11 and the three-dimensional decoration portion 12 are integrally molded using a synthetic resin material, which has the above-described configuration, can be easily formed by a molding method by injection compression molding. Obtainable. That is, for example, as shown in FIGS. 5(a) to 5(d), an injection compression molding apparatus 50 having substantially the same configuration as the injection compression molding apparatus described in JP-A-61-211012 is preferably used. A gate 53 for supplying a synthetic resin material is provided in the central portion of the fixed die 51, and between the fixed die 51 and the movable die 52 in which an uneven pattern having a shape corresponding to the three-dimensional decorative portion 12 is formed on the pressing surface. A synthetic resin material is supplied from the gate 53 into the cavity 54 (see FIG. 5A). After that, the movable die 52 is brought close to the fixed die 51, and the supplied synthetic resin material is pressed and compressed (see FIGS. 5B and 5C), so that the sheet-shaped base 11 is 0.2 to 0. The decorative sheet 10 having a thickness of 0.8 mm and integrally formed with the three-dimensional decorative portion 12 can be easily formed (see FIG. 5D).

Further, in this embodiment, the through hole 40 formed in the sheet-shaped base portion 11 of the decorative sheet 10 can be easily provided at the time of molding by the injection compression molding described above. That is, as shown in, for example, FIGS. 5B to 5D, in order to prevent the synthetic resin material supplied into the cavity 54 from flowing backward through the gate 53 during compression molding by the movable mold 52, the movable mold 52 is movable. When performing a gate cut to project the closing pin 52a from the mold 52 to close the outlet 53a of the gate 53 (see FIGS. 5B and 5C), the closing pin 52a is formed into a sheet-shaped base portion. It is left in a state of penetrating the central portion of 11 (see FIG. 5C). Thereby, when the decorative sheet 10 is taken out from the movable mold 52 and the fixed mold 51 as a product after the synthetic resin material is cured, the closing pin 52a is pulled out from the decorative sheet 10 so that the through hole 40 is formed. It is possible to easily form the central portion of the base portion 11.

In the present embodiment, the through hole 40 formed in the sheet-shaped base 11 of the decorative sheet 10 is preferably a disc gate 55 as shown in FIG. 6 as a gate for supplying the synthetic resin material into the cavity 54. By using it, it can be provided at the time of molding by injection compression molding. That is, the disc gate 55 is a gate used when molding a product having a hole in the central portion or a ring-shaped or cylindrical product, and includes a thin disk-shaped gate 55a. Further, the disc gate 55 has a function of preventing the resin material from being deformed due to the flow orientation and preventing the formation of a weld line. Since the disc gate 55 is punched out by a punch die after the decorative sheet 10 is formed or removed by machining, the removed portions form the large through holes 40 and the central portion of the sheet-shaped base portion 11. Can be easily formed. By using the disc gate 55, it is possible to shorten the molding cycle of the decorative sheet 10.

Further, in the present embodiment, the sheet-shaped base 11 can be subjected to printing, foil stamping, ruled stamping, or thermoforming. As a result, it becomes possible to further improve the decorativeness and design of the decorative sheet 10. For example, by performing these processes on the flat surface portion of the sheet-shaped base 11, it is possible to efficiently process and to easily improve the variety of decoration. The ruled line can be easily formed on the sheet-shaped base 11 at the time of molding by injection compression molding, for example, by providing a convex line on a corresponding portion of the movable die 52. Since the sheet-shaped base portion 11 is scored, it is possible to bend the decorative sheet 10 along the score and easily process it to have a predetermined three-dimensional shape, for example, without jointing. This makes it possible to create a daily-use size individual box.

Further, according to the decorative sheet 10 of the present embodiment having the above-described configuration, it is possible to preferably use it by bending it, and it is possible to form a variety of three-dimensional patterns and the like, and to add another accent. By applying it, it becomes possible to further improve the decorative property and the design property, and also the functionality is excellent.

That is, according to the present embodiment, since the decorative sheet 10 preferably has the sheet-shaped base portion 11 having a thickness of 0.2 to 0.8 mm, it can be easily curved to have a bottomed cylindrical shape. It becomes possible to easily attach it integrally to the curved outer peripheral surface of the tubular body portion 21a of the container body 21. Further, since the three-dimensional decoration unit 12 has a solid three-dimensional shape, it is possible to effectively emphasize the three-dimensional effect, and it is possible to emphasize the brightness feeling and the depth feeling due to the reflection of light. As a result, it is possible to easily form the decorative container 20 excellent in decorativeness and design, and the through hole 40 is provided in the region other than the portion of the sheet-shaped base 11 where the three-dimensional decorative portion 12 projects. Since the openings are formed, the through holes 40 serve as another accent, and the decorativeness and the design can be further improved.

Further, since the through hole 40 is formed in the area other than the portion of the sheet-shaped base 11 where the three-dimensional decoration portion 12 projects, it is possible to reduce the weight of the decoration sheet 10 and at the same time, When the decorative sheet 10 is attached to, for example, the outer peripheral surface of the tubular body portion 21a of the container body 21, it is possible to cause the through hole 40 to function as an air bleeder and firmly adhere to the outer peripheral surface. It is possible to improve drainage and unique appearance. Further, the through hole 40 can be made to function as a locking hole, and it is possible to attach an additional decorative part or the like for self-arrangement.
