Description

  The present invention mainly relates to a method for forming a pattern such as condensation on the outer surface of a beverage container used for a display.

  For example, a display showcase is installed at a store such as a coffee shop or a restaurant, and sample products with dishes, desserts, and the like are displayed on the showcase. In addition to these sample products such as dishes, beverages such as alcohol are often displayed in the showcase.

  Such beverages for display are often displayed using commercially available beer bottles, beverage cans and the like. However, cold beverages that are actually provided in restaurants, etc., appear to have a refreshing sensation due to the condensed water adhering to the outer surface of the beverage container due to the temperature difference from the outside air. Has the disadvantage that it lacks the presence of condensed water and lacks reality.

  Therefore, if a commercially available beer bottle or the like is cooled and displayed in a showcase, it is possible to attach condensed water to the outer surface of the beer bottle or the like. However, in such a method, moisture evaporates with time and disappears. For this reason, it is impossible to maintain a state where condensation is constantly attached. In addition, it is conceivable to produce a beverage container having such a state that condensed water adheres to it using a resin sample. However, there is a disadvantage that costs increase such as manufacturing a mold. Furthermore, it is difficult for a resin sample by a mold to reproduce a fine portion of natural dew condensation water, resulting in a lack of realism.

In addition, although the coating method which prints a fine uneven | corrugated (peel-like) pattern on the surface of a drink can etc. like patent document 1 is known, the refreshing agglomeration like droplets by the said coating method It was difficult to form a feeling pattern.

  According to the method for forming a condensation pattern on a beverage container according to the present invention, a condensation pattern can be easily applied to the beverage container.

  Next, the method for forming a dew-like pattern on a beverage container according to the present invention will be described below with reference to the accompanying drawings by giving a preferred embodiment. In the examples, a case where a pattern is applied to a commercially available aluminum can filled with a soft drink or an alcoholic drink is illustrated. In addition, as a drink container which can apply this invention, it is not limited to an aluminum can, Beverage containers, such as a plastic bottle, glass, a beer mug, a glass, are employable.

  FIG. 1 is an overall perspective view showing an aluminum can 10 having a dew-like pattern formed by the method according to the present embodiment. The aluminum can 10 includes a main body 12 formed in a cylindrical shape and designed in various ways by printing or the like, and a cap 14 attached to an upper portion of the main body 12. Condensation is formed over the entire outer surface 16 of the aluminum can 10. Pattern (condensation pattern) is given. As shown in an enlarged view in FIG. 1, a water repellent layer 20 is formed on the outer surface 16 of the aluminum can 10 by applying a water repellent wax (water repellent). Any wax may be used as long as it has water repellency. For example, a commercially available wax used when washing a vehicle can be used. Various waxes such as solid wax and semi-solid wax can be employed.

  On the outer surface of the water repellent layer 20, a dew-like portion 24 is formed in which a colorless and transparent hydrophilic epoxy resin (thermosetting resin) 22 is condensed in the form of water droplets. That is, the dew-like portion 24 is formed in a random size and non-uniformly over substantially the entire outer surface 16 of the aluminum can 10, and forms a dew-like pattern such that dew condensation is attached to the aluminum can 10. Therefore, due to the water repellent action (repellent action) between the water repellent layer 20 and the epoxy resin 22, the epoxy resin 22 aggregates in the form of water droplets on the outer surface 16 of the aluminum can 10 and then hardens to form the dew-like part 24. is doing. In addition, the dew-like part 24 formed in the main body 12 of the aluminum can 10 has a shape that swells from the top to the bottom due to its own weight, as in the case of an actual water drop (see the enlarged part in FIG. 1).

  As shown in FIG. 2C, the epoxy resin 22 is applied to the aluminum can 10 by spraying in a mist form from a nozzle 26 such as a spray gun. Therefore, the epoxy resin 22 having a viscosity coefficient before curing set to about 220 to 250 mPa · s (millipascal second) is used. By setting the viscosity coefficient of the epoxy resin 22 in this range, the epoxy resin 22 can be suitably sprayed with a spray gun, and the epoxy resin 22 is securely attached to the outer surface 16 without dripping from the aluminum can 10. Can be.

  Next, a specific procedure for forming a dew-like pattern by the method according to the embodiment will be described.

  First, as shown in FIG. 2 (a), the aluminum can 10 is wiped dry with a cloth 28 to remove dirt adhered to the outer surface 16. Next, a wax is applied to the outer surface 16 of the aluminum can 10 in the form of a thin film. At this time, the aluminum can 10 may be polished using the cloth 28 so that the wax spreads over the entire outer surface 16 of the aluminum can 10. As a result, as shown in FIG. 2B, a water-repellent layer 20 made of wax is formed on the outer surface 16 of the aluminum can 10.

  Next, as shown in FIG. 2C, the epoxy resin 22 is spray-coated on the water-repellent layer 20 from the nozzle 26 of the spray gun. At this time, since the epoxy resin 22 whose viscosity coefficient is set to 200 to 250 mPa · s is used, the epoxy resin 22 can be sprayed in a mist form. In addition, the epoxy resin 22 sprayed on the aluminum can 10 reliably adheres to the outer surface 16 and does not flow down on the outer surface 16. When the epoxy resin 22 adheres to the water-repellent layer 20, the hydrophilic epoxy resin 22 aggregates like water droplets by a repelling action with the wax (water-repellent layer 20), and the dew-like part 24 which becomes the main body of the dew-like pattern. Is formed.

  Here, since the condensed water adhering to the actual beverage container has various sizes, the condensed water formed on the aluminum can 10 in order to apply a more realistic condensed pattern to the aluminum can 10. It is desirable that the size of the shape portion 24 is also non-uniform. Therefore, by changing the amount of the epoxy resin 22 applied depending on the location of the aluminum can 10, the dew-like portions 24 of various sizes can be formed. Specifically, since the size of the condensation-like portion 24 is proportional to the amount of the epoxy resin 22 that condenses, the amount of the epoxy resin 22 applied to the aluminum can 10 is adjusted for each part. That is, when the large dew-shaped part 24 is formed, the application amount of the epoxy resin 22 is increased. On the other hand, in order to reduce the dew-shaped part 24, the application amount of the epoxy resin 22 is decreased.

  When spray application of the epoxy resin 22 is completed, the aluminum can 10 is dried at room temperature. As a result, as shown in FIG. 2D, the epoxy resin 22 (condensation-like portion 24) is cured on the outer surface 16 of the aluminum can 10, and a condensation-like pattern is formed.

  As described above, according to the method for forming a dew-like pattern according to the embodiment, a dew-like pattern can be easily formed on the outer surface 16 of the aluminum can 10. Thereby, a realistic refreshing feeling can be given to the aluminum can 10, and it can be suitably used as a display product. Further, since the dew-like pattern can be formed without using a mold or the like, the manufacturing cost can be reduced. By changing the coating amount of the epoxy resin 22 at the site of the outer surface 16 of the aluminum can 10, it is possible to form a dew-like portion 24 having a different size, and a more realistic dew-like pattern on the aluminum can 10. Can be applied. In addition, the dew-like portion 24 formed on the side surface of the aluminum can 10 can form a natural droplet form by the gravitational action.

  Since the epoxy resin 22 is set to an appropriate viscosity, the epoxy resin 22 can be suitably sprayed onto the aluminum can 10, and the epoxy resin 22 does not drop after being applied to the aluminum can 10. . Furthermore, since a commercially available wax can be used as the water repellent, the raw material cost does not increase.

  In the examples, the case where wax is employed as the water repellent is exemplified, but other water repellents may be used as long as they have water repellency and can be applied to beverage containers such as aluminum cans and bottles. It is possible to use. Moreover, as a thermosetting resin, it is not necessarily limited to the epoxy resin 22 used in the Example, For example, if it is a colorless and transparent resin and hydrophilic resin, a polyester resin etc. can be employ | adopted. Furthermore, the water repellent agent does not necessarily have to be applied to the entire outer surface of the beverage container, and may be applied to the outer surface in a patchy manner. Thereby, an epoxy resin concentrates on the site | part which is not apply | coated with the water repellent among the outer surfaces of a drink container, and it becomes possible to form a dew-like part suitably.

It is a whole perspective view which shows the aluminum can in which the dew-like pattern was given. It is explanatory drawing which shows the process which gives a dew-like pattern to an aluminum can, (a) shows the state which wiped the aluminum can, (b) shows the state which applied the wax to the aluminum can, (c), The state where the epoxy resin is spray-coated on the aluminum can is shown, and (d) shows the state where the condensation pattern is applied to the aluminum can.
