Description

[Technical field]

[0001] The present invention relates to a tube container. [Background technology]

[0002] Tube containers have been known for some time as containers for cosmetics and medicines in liquid, gel, cream, etc. Co-extrusion tube molded products of this type are best suited for products that require design, such as cosmetics, because they are multi-layered and impart barrier properties, but do not produce steps in the appearance due to seams.

[0003] In the case of products filled in such tube containers, consumers have no way of determining whether the contents of the product are genuine when it is unused. In addition, in general, for branded products such as high-end cosmetics, the added value of the product is high in the contents compared to the product price, whereas the cost ratio of the container is low. Therefore, by imitating the container, there is a risk that counterfeit products can be distributed at low prices.

[0004] Therefore, a method has been used in which anti-counterfeiting printing is applied to containers using black light ink that emits light in response to ultraviolet light. Although this is normally invisible, genuine products can be identified by irradiating them with ultraviolet light (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-176970 [Patent Document 2] Japanese Utility Model Application Publication No. 04-045081 Summary of the Invention [Problem to be solved by the invention]

[0006] The above-mentioned technology for applying anti-counterfeit printing to containers has the following problems. That is, the side surface of the container is a design surface, and is used for decoration by various secondary processes such as printing, labels, transfer, and glitter, and for indicating the contents, etc. For this reason, it is difficult to provide an anti-counterfeit printing frame in terms of the design of the container. Furthermore, in order to prevent the anti-counterfeit printing from being imitated, it is desirable to keep the anti-counterfeit printing secret, and it is undesirable to provide an unnatural unprinted area.

[0007] In addition, black light ink, which emits light in response to ultraviolet light, has weaker adhesion than inks used in regular printing. Furthermore, olefin resins such as polyethylene and polypropylene are often used as materials for moldings, but olefin resins are non-polar, making them difficult to print on, and so corona treatment or chemical treatment is required before printing.

[0008] Therefore, an object of the present invention is to provide a tube container capable of preventing counterfeiting without providing a mark on the design surface, a tube container filled with contents, a method for manufacturing a tube container, and a method for evaluating a tube container. [Means for solving the problem]

[0009] According to one aspect of the present invention, a tube container comprises a container body including a body on which a decorative surface is formed, a shoulder provided at one end of the body, and a head provided on the shoulder, the container body having a tube molded product forming the edge of the body side of the body and the shoulder, and a head molded product integrally molded with the tube molded product and forming the shoulder and the head, a cap fixed to the head, and an anti-counterfeiting display portion formed in the area forming the shoulder of the tube molded product.

[0010] According to one aspect of the present invention, a tube container containing a content includes the above-mentioned tube container and a content.

[0011] According to one aspect of the present invention, a manufacturing method for a tube container is a manufacturing method for a tube container having a container body with a body portion, a shoulder portion, and a head portion, which includes the steps of: forming a tubular molded product by co-extrusion molding; performing a surface treatment on a predetermined area including an area on which the design surface and the anti-counterfeiting mark of the molded product are to be printed; printing the design surface and the anti-counterfeiting mark on the surface-treated molded product in an area that will become the design surface and an area on which the anti-counterfeiting mark is to be printed; integrally molding the molded product and the head molded product; and providing the anti-counterfeiting mark printed on the molded product on the shoulder portion.

[0012] According to one aspect of the present invention, a method for judging a tube container includes a tube container having a container body including a body on which a decorative surface is formed, a shoulder provided at one end of the body, and a head provided on the shoulder, and the tube molded product forms the edge of the body side of the body and the shoulder, and a head molded product that is integrally molded with the tube molded product and forms the shoulder and the head, a cap fixed to the head, and an anti-counterfeiting display part formed in an area that forms the shoulder of the tube molded product, and contents to be filled into the container body, wherein a display process for the anti-counterfeiting display part is performed on the tube container in a predetermined attitude, information on the anti-counterfeiting display part is obtained, and the tube container is judged from the obtained information on the anti-counterfeiting display part. Effect of the Invention

[0013] According to the present invention, it is possible to provide a tube container capable of preventing counterfeiting without providing a mark on the design surface, a tube container filled with contents, a method for manufacturing a tube container, and a method for evaluating a tube container.

[0015] Hereinafter, a tube container 1 and a content-containing tube container 100 according to one embodiment of the present invention will be described with reference to Figs. 1 to 7. Figs. FIG. 1 is a side view showing the configuration of a content-containing tube container 100 according to an embodiment of the present invention, and FIG. 2 is a side view showing the configuration of a container body 11 before filling the content 2 of the tube container 1 used in the content-containing tube container 100. FIG. 3 is a cross-sectional view showing the configuration of the tube molded product 31 in the body part 21 and the shoulder part 22 and the area F1 in which the counterfeit prevention display part 13 is arranged as the main part configuration of the container body 11. FIG. 4 is a side view showing the relationship between the container body 11 and the cap 12 of the tube container 1. FIG. 5 is a flow chart showing an example of a manufacturing method of the content-containing tube container 100, and FIG. 6 is a flow chart showing an example of a manufacturing method of the container body 11. FIG. 7 is a flow chart showing an example of a counterfeit judgment of the content-containing tube container 100.

[0016] As shown in FIG. 1, the content-containing tube container 100 includes a tube container 1 and a content 2. The content-containing tube container 100 is distributed as a product in a sealed state with the content 2 filled in the tube container 1. Here, the content 2 is, for example, a relatively viscous liquid or semi-solid such as liquid, gel, or cream. For example, the content 2 is a cosmetic or a medicine. Specific examples of the content 2 include milky lotion, moisturizing cream, facial cleanser, cleansing agent, sunscreen, shaving agent, hair styling agent, hair care agent, and foundation.

[0017] As shown in FIG. 1, the tube container 1 includes a container body 11, a cap 12, and a counterfeit prevention display unit 13.

[0018] 1 and 2, the container body 11 includes a trunk portion 21, a shoulder portion 22, and a head portion 23. The container body 11 is formed by integrally molding a tube molded product 31 and a head molded product 32.

[0019] The body 21 is formed in a tube shape. One end of the body 21 is integrally provided with a head 23 via a shoulder 22. The other end of the body 21 is open before the content 2 is filled, as shown in FIG. 2. After the content 2 is filled, the other end of the body 21 is sealed by welding or adhesion using heat sealing or the like, as shown in FIG. 1. That is, after the content 2 is filled, the other open end of the body 21 is sealed by forming a seal portion. The body 21 is formed so as to be deformable when an external force is applied.

[0020] The shoulder portion 22 is continuous with the body portion 21 and the head portion 23. The shoulder portion 22 is inclined or curved with respect to the axial direction of the tube container 1 so that the width of the shoulder portion 22 becomes smaller from the body portion 21 side toward the head portion 23 side, for example.

[0021] The head 23 is formed in a cylindrical shape. A discharge hole for discharging the content 2 is formed at the tip of the head 23. In addition, the head 23 is appropriately formed with, for example, a male screw portion 23a into which the cap 12 is screwed, a protrusion into which the cap 12 is fitted, and the like.

[0022] The tube molded product 31 is formed in a cylindrical shape. As shown in Fig. 1 to Fig. 3, the tube molded product 31 forms the body 21 and the edge of the shoulder 22 on the body 21 side and on the upper surface side. That is, the tube molded product 31 forms a part of the exterior of the container body 11, and the outer surface is exposed to the outside.

[0023] For example, the tube molded product 31 is formed by a co-extrusion molding method. The tube molded product 31 has, for example, a single-layer or multi-layer structure. The tube molded product 31 is formed of, for example, PE (Polyethylene). An example of a PE-based material is LDPE (Low Density Polyethylene). The material forming the tube molded product 31 may also be a multi-layer structure containing LLDPE (Linear Low Density Polyethylene) or HDPE (High Density Polyethylene) in addition to LDPE. As specific examples, several examples of layer configurations of the tube molded product 31 will be described.

[0024] As a first example, the tube molded product 31 has a multi-layer structure, and the layer configuration from the outer layer side to the inner layer side is LDPE (60-200 μm) / adhesive layer (1-30 μm) / middle layer (10-100 μm) / adhesive layer (1-30 μm) / LDPE (120-250 μm). In the tube molded product 31 of the first example, the inner side (inner layer) is formed from a PE-based material in order to fuse with the head molded product 32, and the LDPE can be a resin material derived from petroleum, biomass, recycled PE, or a mixture thereof.

[0025] Here, recycled PE is, for example, recycled low-density polyethylene resin. In the technical field, the term "recycled resin" refers to a material that is obtained by collecting used resin products or waste from the manufacturing process of resin products and processing them so that they can be used as materials or raw materials for new products. Therefore, recycled low-density polyethylene resin may be derived from used resin products or waste from the manufacturing process of resin products. It is preferable that recycled low-density polyethylene resin is derived from used resin products.

[0026] The recycled low-density polyethylene resin in this embodiment meets, for example, the following two requirements: (i) having an average molecular weight of 30,000 or more; and (ii) The endothermic peak obtained by differential scanning calorimetry is present only within the range of 100 to 140°C.

[0027] Requirement (i) means that the recycled low-density polyethylene resin used in the present invention is a recycled resin, and is therefore repeatedly subjected to a melt-solidification process for recycling, and although the molecular weight may decrease due to the thermal history, the level of decrease in molecular weight is low. Requirement (ii) means that the recycled low-density polyethylene resin used in the present invention is a recycled resin, and therefore may contain impurities, but the impurities are contained in small amounts that are not detectable by differential scanning calorimetry, or are not contained at all.

[0028] For example, the average molecular weight of recycled low-density polyethylene resin refers to the number average molecular weight (Mn) measured using gel permeation chromatography. Measurement of the number average molecular weight using gel permeation chromatography can be performed using a high-temperature gel permeation chromatograph (high-temperature GPC) device and a styrene-divinylbenzene-based packed column for high-temperature GPC. For example, measurement of the number average molecular weight using gel permeation chromatography can be performed under the following conditions. The number average molecular weight (Mn) can be obtained by creating a calibration curve using monodisperse polystyrene as a standard substance and calculating the molecular weight from the retention time.

[0029] The endothermic peak temperature of the recycled low-density polyethylene resin can be obtained by performing differential scanning calorimetry (DSC) to obtain a differential scanning calorimetry curve (DSC curve). Differential scanning calorimetry can be performed using a differential scanning calorimeter.

[0030] As a second example, the tube molded product 31 is made of LDPE (400 to 500 μm).

[0031] As a third example, the tube molded product 31 has a multi-layer structure, and the layer configuration from the outer layer side to the inner layer side is LDPE (100 to 300 μm) / HDPE (100 to 300 μm). As a fourth example, the tube molded product 31 has a multi-layer structure, and the layer configuration from the outer layer side to the inner layer side is LDPE (acid-modified) + LLDPE (acid-modified) (50 to 220 μm) / intermediate layer (10 to 100 μm) / LDPE (acid-modified) + LLDPE (acid-modified) (100 to 280 μm).

[0032] As shown in Fig. 3, at least a part of the region F1 forming the outer surface of the edge of the shoulder 22 of the tube molded product 31 on the side of the body 21 is provided with an anti-counterfeiting display 13. Also, as shown in Fig. 3, the region F2 forming the outer surface (side surface) of the body 21 of the tube molded product 31 is a design surface, which is used for decoration by various secondary processes such as printing, labels, transfers, and glitter, and for indicating the contents, etc.

[0033] The head molded part 32 forms part of the shoulder portion 22 together with the tube molded part 31. The head molded part 32 also forms the head. The head molded part 32 is integrally connected to the inner surface of the part constituting the shoulder portion 22 of the tube molded part 31 and to the end face of the tube molded part 31 on the head molded part 32 side. The head molded part 32 is made of, for example, PE (Polyethylene).

[0034] The cap 12 is formed so as to be detachable from the head 23. The cap 12 is formed so as to be fixable to the head 23 by screwing or fitting. For example, when the head 23 has a male thread portion 23a, the cap 12 has an internal female thread portion which screws into the male thread portion 23a. Also, for example, when the head 23 has a protrusion, the cap 12 has an internal fixing portion which engages with or fits into the protrusion. The cap 12 is formed, for example, by injection molding. The cap 12 is formed, for example, from PP (Polypropylene) or HDPE.

[0035] The cap 12 is formed, for example, in a shape that allows at least a part of the counterfeit prevention display portion 13 to be visible from the outside when the cap 12 is fixed to the container body 11. For example, as shown in Fig. 4, the outer shape of the cap 12 is formed to be smaller than the outer shape of the container body 11. As shown in Fig. 4, the cap 12 is formed in a shape that exposes the shoulder portion 22 by a width H between the outer peripheral surface of the cap 12 and the boundary between the body portion 21 and the shoulder portion 22 of the container body 11 when the cap 12 is fixed to the head portion 23. In other words, the container body 11 and the cap 12 are formed in a shape that causes a dimensional difference (2H) between the outer peripheral surface of the cap 12 and the outer peripheral surface of the body portion 21 (the outer peripheral edge of the shoulder portion 22).

[0036] Here, the width H between the outer peripheral surface of the cap 12 and the boundary between the body 21 and the shoulder 22 of the container body 11 is set, for example, to a width that is equal to or greater than a width that allows at least a part of the anti-counterfeiting indication 13 to be visible from the outside. That is, in a state in which the cap 12 is fixed to the container body 11, the tube container 1 is formed such that the anti-counterfeiting indication 13 formed in the region F1 present in the shoulder 22 of the tube molded product 31 can be visible from the outside. For example, the width of the region F1 present in the shoulder 22 of the tube molded product 31 is set to 1.1 mm to 1.8 mm, and the width H between the outer peripheral surface of the cap 12 and the boundary between the body 21 and the shoulder 22 of the container body 11 is set to 0.5 mm or greater.

[0037] The counterfeit prevention display part 13 is provided on the shoulder part 22 of the container body 11. For example, the counterfeit prevention display part 13 is disposed in an area F1 constituting the shoulder part 22 of the tube molded product 31 shown in FIG. 3. The counterfeit prevention display part 13 is a display that enables identification of a counterfeit (imitation) of the content-containing tube container 100. The counterfeit prevention display part 13 is a display that enables identification of whether or not the product is a counterfeit, for example, printed with ink that emits light in response to ultraviolet light (hereinafter also referred to as "black light fluorescent ink"). For example, the counterfeit prevention display part 13 is a display that cannot be seen under natural light or fluorescent light, and emits light in response to ultraviolet light when irradiated with black light, enabling identification of the authenticity of the product.

[0038] The counterfeit prevention display unit 13 may be formed of ink other than the ink that emits light in response to ultraviolet light. For example, the counterfeit prevention display unit 13 may be formed of ink that changes color due to ultraviolet light or magnetism, or ink that changes color depending on the angle, or a hologram that shows letters or pictures when light is applied. The ink for printing the counterfeit prevention display unit 13 may be functional ink such as thermochromic ink, photochromic ink, or infrared ink. However, in order to prevent counterfeiting (imitation) of the counterfeit prevention display unit 13, it is preferable that the counterfeit prevention display unit 13 has a configuration that allows counterfeiting to be determined by a special process (display process) that displays the counterfeit prevention display unit 13, such as irradiating it with black light, and that allows concealment such as being invisible under normal circumstances.

[0039] Next, an example of a method for manufacturing the content-containing tube container 100 thus configured will be described with reference to FIGS. First, an example of manufacturing the tube molded product 31 will be described. For example, a multi-layered tubular molded product is extruded by co-extrusion (step ST11). Next, the extruded molded product is solidified by water cooling (step ST12). The solidified molded product is cut to a predetermined length (step ST13). Next, a surface treatment is performed on a predetermined range of the cut molded product (step ST14). The surface treatment is performed on a range F3 of the molded product including an area F1 where the counterfeit prevention display portion 13 is printed and an area F2 that becomes the design surface, but as shown in FIG. 6, the surface treatment is not performed on both ends of the molded product.

[0040] Next, printing is performed on the surface-treated area that is to become the design surface of the container body 11 and the area where the anti-counterfeiting display unit 13 is to be provided, to form the design surface and the anti-counterfeiting display unit 13 (step ST15). Here, printing for forming the design surface and the anti-counterfeiting display unit 13 includes printing with ink, applying ink or paint, and attaching a label. Specific examples of printing for forming the design surface and the anti-counterfeiting display unit 13 include black light fluorescent ink printing or painting, offset printing, silk printing, hot stamping, cold stamping, label attachment, etc.

[0041] The area where the anti-counterfeiting mark 13 is printed or painted is an area provided on the shoulder 22, and is located inside the molded product relative to the edge of the surface-treated area. In other words, a part of the surface-treated area will be trimmed in the next process, and the anti-counterfeiting mark 13 is formed in a position adjacent to this trimming position. Next, the molded product is trimmed (step ST16). Trimming is performed by cutting the parts not used in the body 21 and shoulder 22 of the molded product, specifically, the end side that constitutes the shoulder 22 side. Through these processes, a tube molded product 31 is formed.

[0042] Next, the head molded product 32 is molded integrally with the tube molded product 31 by compression molding, injection molding, or the like (step ST17). At this time, the counterfeit prevention display part 13 printed on the tube molded product 31 is placed on the shoulder part 22. Note that, in order to prevent a step from occurring in the areas of the tube molded product 31 and the head molded product 32, it is preferable to melt and solidify the head molded product 32 with the inner surface of the tube molded product 31, and mold the tube molded product 31 and the head molded product 32 integrally.

[0043] Next, with the cap 12 fixed to the container body 11, the contents 2 are filled from the opening of the end of the body 21 opposite to the end where the shoulder 22 and the head 23 are provided (step ST18). The cap 12 is molded, for example, by injection molding using PP or HDPE separately from the container body 11. Then, the opening of the body 21 is sealed by, for example, heat sealing, ultrasonic sealing, hot air sealing, hot air sealing, etc., and a sealed part is formed, thereby sealing it (step ST19). Here, hot air sealing is, for example, a method of blowing hot air onto the inner surface of the opening side of the tube molded product 31 (body 21) to semi-melt the inner surface side of the tube molded product 31, and then crimping in the semi-melted state. Through these steps, the tube container 100 containing the contents is manufactured.

[0044] Next, an example of a method for judging the thus configured tube container 1 and the content-containing tube container 100 will be described with reference to Fig. 7. Here, the method for judging the tube container 1 includes judging whether the counterfeit prevention indication 13 is correctly formed in a shipping inspection at the time of manufacture, and judging the authenticity of the tube container 1 after shipping and before filling the content 2 into the tube container 1. In addition, the judgment of the content-containing tube container 100 includes judging the authenticity after filling the content 2 into the tube container 1 to become a finished product.

[0045] As shown in FIG. 7, first, the tube container 1 or the tube container 100 containing the contents is placed at a predetermined position in a predetermined posture (step ST21). Here, the predetermined posture is a posture that allows information on the counterfeit prevention display part 13 to be obtained when the counterfeit prevention display part 13 is displayed, for example, a posture in which the container body 11 is downward and the cap 12 is upward. As a specific example, the predetermined posture is a posture in which, for example, when a single or multiple tube containers 1 or tube containers 100 containing the contents are stored in a presentation box or a storage box, the cap 12 is upward, and the cap 12 and a part of the shoulder part 22 are visually recognized. In addition, the predetermined position is a position where at least the next process is performed. The tube container 1 or the tube container 100 containing the contents may be transported to the predetermined position by a transport device such as a conveyor, or may be transported by an operator.

[0046] Next, a display process of the counterfeit prevention display part 13 is performed on the tube container 1 or the tube container 100 containing the contents (step ST22). In this embodiment, since the counterfeit prevention display part 13 is formed of ink that emits light in response to ultraviolet light, the display process of the counterfeit prevention display part 13 is the irradiation of black light (ultraviolet light) onto the area F1 where the counterfeit prevention display part 13 is provided. As a specific example, the display process is performed by irradiating black light from the cap 12 side of the tube container 1 or the tube container 100 containing the contents, that is, from above the tube container 1 or the tube container 100 containing the contents.

[0047] Here, the irradiation with black light may be performed by an irradiation device that irradiates black light arranged above one or more tube containers 1 or tube containers 100 containing contents, or, for example, black light may be irradiated by an operator using an ultraviolet LED or the like. When the black light is irradiated to the area F1, if the tube container 1 or the tube container 100 containing contents is genuine or the tube container 1 has been manufactured well, the counterfeit prevention display part 13 provided in the area F1 reacts to the ultraviolet light and emits light, whereas if the tube container 100 containing contents is counterfeit or the manufactured tube container 1 is defective, no emitting part appears in the area F1 since the counterfeit prevention display part 13 is not provided in the area F1.

[0048] Next, the information of the counterfeit prevention display part 13 is obtained (step ST23). For example, the information of the counterfeit prevention display part 13 emitted by irradiating it with black light is obtained by an imaging device such as a camera or a reading device such as a scanner. The information of the counterfeit prevention display part 13 may be obtained by an operator visually recognizing the information of the counterfeit prevention display part 13. Since the tube container 1 and the content-containing tube container 100 have a shape in which the container body 11 and the cap 12 are shaped such that the region F1 of the width H can be visually recognized from the outside, the information of the illuminated counterfeit prevention display part 13 can be obtained without removing the cap 12 from the container body 11.

[0049] Next, the tube container 1 or the tube container 100 with contents is judged as a judgment process based on the information acquired from the counterfeit prevention display section 13 (step ST24). Here, the judgment includes judgment of the quality of the manufactured tube container 1 and judgment of the counterfeit (authenticity) of the tube container 1 before the finished product is created or the tube container 100 with contents, which is the finished product. The quality judgment is a judgment process for judging whether the manufactured tube container 1 is a good product or a defective product. The counterfeit judgment is, for example, an authenticity judgment for judging whether the tube container 1 or the tube container 100 with contents is a regular product or a counterfeit product. For example, when the information of the counterfeit prevention display section 13 is acquired by an imaging device or a reading device, the judgment device judges the tube container 1 or the tube container 100 with contents as a good product or a regular product, and when the information of the counterfeit prevention display section 13 is not acquired by an imaging device or a reading device, the judgment device judges the tube container 1 or the tube container 100 with contents as a defective product or a counterfeit product.

[0050] Here, the judgment device includes, for example, a processor and a memory, and the memory stores information on the anti-counterfeiting marking part 13 of the genuine product, and a judgment program or the like that judges whether the tube container 100 containing the content is genuine or non-genuine based on the information on the anti-counterfeiting marking part 13 of the genuine product and the information on the anti-counterfeiting marking part 13 acquired.

[0051] Also, for example, when there is a possibility that a counterfeit anti-counterfeiting mark equivalent to the anti-counterfeiting mark 13 is formed on a counterfeit tube container 1 or a tube container containing contents, or when there is a possibility that the anti-counterfeiting mark 13 is formed on a defective tube container 1 but is printed differently in position, size, shape, etc. from the anti-counterfeiting mark 13 of a good product, thresholds for the shape, size, position information, etc. of the anti-counterfeiting mark 13 of a genuine product (good product) may be stored in a memory of the determination device, and the determination device may determine whether the anti-counterfeiting mark 13 is genuine or good from the acquired shape, size and / or position information, etc. of the anti-counterfeiting mark 13 and the thresholds. Also, the determination may be made by an operator judging the authenticity or goodness of the anti-counterfeiting mark 13 based on visual confirmation of the anti-counterfeiting mark 13.

[0052] In the content-containing tube container 100 and tube container 1 thus configured, the counterfeit prevention mark 13 is not provided in the area F2 which is the design surface of the body 21 of the tube molded product 31, but is provided in the area F1 located on the shoulder 22. Therefore, the counterfeit prevention mark 13 can prevent counterfeiting without compromising the design of the tube container 1. In addition, since it is not necessary to provide the counterfeit prevention mark 13 on the design surface, the print frame of the counterfeit prevention mark 13 does not appear on the design surface, making it possible to conceal the counterfeit prevention mark 13 and preventing imitation of the counterfeit prevention mark 13.

[0053] Furthermore, since the shoulder portion 22 is a portion that does not look unnatural even if it is a non-printed area, providing the counterfeit prevention indication portion 13 on the shoulder portion 22 can improve concealment.

[0054] Furthermore, by forming the region F1 where the counterfeit prevention display part 13 is provided in a part of the tube molded product 31, it is possible to perform a surface treatment before printing in order to obtain adhesion to the black light fluorescent ink. This makes it possible to prevent the printing of the counterfeit prevention display part 13 from peeling off during transportation or handling.

[0055] In addition, the tube container 1 and the tube container 100 containing the contents can be easily identified as counterfeit by forming the shape of the container body 11 and the cap 12 such that the region F1 can be seen from the outside by the width H. That is, the region F1 can be seen from the outside when the tube container 1 and the tube container 100 containing the contents are placed side by side in a box for transportation or the like with the cap 12 facing upwards and stored in the box. This makes it possible to irradiate the region F1 with black light while the tube container 1 and the tube container 100 containing the contents are stored in the box, thereby making it possible to see the counterfeit prevention display section 13. Therefore, the tube container 1 and the tube container 100 containing the contents can be easily identified as counterfeit.

[0056] According to the tube container 1 and the content-containing tube container 100 according to the above-described embodiment, counterfeit prevention is possible without providing a mark on the design surface.

[0057] The present invention is not limited to the above-described embodiment. For example, as in a modified example shown in Fig. 8, the area F1 in which the counterfeit prevention display part 13 is arranged may be provided in the head molded part 32 of the shoulder part 22. However, since it is difficult to perform surface treatment of the head molded part 32 before printing, when providing the counterfeit prevention display part 13 on the head molded part 32, it is preferable to provide the counterfeit prevention display part 13 by digital printing, insert molding, hydraulic transfer, thermal transfer, pad printing, or the like.

[0058] The present invention is not limited to the above-mentioned embodiment, and can be modified in various ways without departing from the gist of the present invention. The embodiments may be combined as appropriate, and in that case, the combined effect can be obtained. Furthermore, the above-mentioned embodiment includes various inventions, and various inventions can be extracted by combinations selected from the multiple components disclosed. For example, if the problem can be solved and the effect can be obtained even if some components are deleted from all the components shown in the embodiment, the configuration from which the components are deleted can be extracted as an invention.
