Description

  The present invention relates to a portable insulated tank for storing liquid.

  In recent years, the number of people who perform various outdoor leisure activities has increased. Marine leisure activities such as surfing, windsurfing, and fishing are also available regardless of the season.

  Outdoor leisure generally provides a sense of satisfaction and refreshment, but the body is more easily soiled than indoor leisure, and marine leisure is particularly dirty due to the tide and sand. For this reason, after enjoying marine leisure, it is necessary to wash the body with fresh water. Otherwise, the refreshing feeling after leisure will not be obtained and the inside of a private car or train will be soiled with a dirty body on the way home.

  However, there are no water supply facilities other than specific beaches such as beaches where marine leisure is conducted. Moreover, the water supply facilities at the beach and the seaside rest area are usually not open during the season other than the beach season. In the warm season, it is not impossible to prepare water in a portable tank by yourself and wash your body with this water, but in cold seasons other than the hot summer season, It is hard to wash.

  On the other hand, hot water can be carried in a thermos bottle, but a large amount of hot water cannot be carried. In addition, thermos bottles and similar thermal insulation containers are relatively expensive and fragile and must be handled with care, and are not suitable as containers for carrying a large amount of hot water to the wild.

  For this reason, people who prefer wild leisure are looking forward to the emergence of a portable, insulated tank that is durable, inexpensive and easy to carry.

  Patent Document 1 proposes a technique related to a heat insulating container using a foamed resin material. Patent Document 1 includes a plastic outer container including a foam layer in a part thereof and having an upper opening, and an upper opening. There is disclosed a plastic heat insulating container including a plastic inner container disposed in an outer container and a plastic lid provided in an upper opening of the outer container.

JP 2010-2222037 A

  However, Patent Document 1 does not meet the expectation of people who perform marine leisure, but relates to a heat insulating container for beverages. Patent Document 1 describes that a large amount of liquid enough to wash the body is accommodated. We do not consider it and do not assume rough handling.

  The present invention has been made in view of the demands of people who prefer wild leisure. An object of the present invention is to provide a portable heat insulation tank that can easily store a large amount of liquid, is excellent in heat insulation and heat retention, is lightweight and easy to carry, and can withstand rough handling.

  The present invention for solving the above-mentioned problems is a portable heat insulation tank comprising a plastic container having an opening, a lid for covering the opening, and a coating layer made of foamed resin provided on the outer surface of the plastic container. It is.

  In this configuration, since the coating layer made of the foamed resin has a heat insulating action, the liquid inside the plastic container inside the coating layer can be kept warm. In addition, since the plastic container and the coating layer are light and the container itself is light, the portability when a large amount of hot water is added is excellent. Further, since the plastic container has a certain rigidity, the strength of the portable heat insulating tank can be maintained, and the impact resistance of the plastic container can be enhanced by the coating layer.

  The said structure WHEREIN: The said coating layer consists of foaming polyurethane, The average thickness is 10-30 mm, The said plastic container has a handle, The coating layer which consists of foamed resin is formed in the said handle. There can be no configuration.

  If the thickness of the coating layer made of polyurethane foam is too thin, the heat retention may be insufficient, and if it is too thick, the portability may be impaired. For this reason, the average thickness of the coating layer made of polyurethane foam is regulated within a range of 10 to 30 mm.

  In this configuration, a handle is provided on the plastic container so that a coating layer made of foamed resin is not formed on the handle. With this configuration, it is possible to realize a portable heat insulation tank that is easy to carry and has sufficient heat insulation properties.

  Here, as the foamed resin, foamed styrene, foamed polyethylene, foamed polypropylene, foamed polyurethane and the like are suitable. Among them, foamed polyurethane (urethane foam) is suitable as a material for the coating layer because it is easily available and inexpensive. It is.

  The said structure WHEREIN: At least the bottom part of the surface of a coating layer can be set as the structure by which the surface leveling is made | formed by the iron.

  The surface leveling by the trowel may be performed on the entire surface or only a part of the surface, but it is preferable to perform the surface leveling on the bottom surface in order to prevent the container from overturning. If the entire surface is smoothed, the surface is smoothed so that it is easy to see and to be stored and carried.

  The said structure WHEREIN: The said coating layer can be set as the structure by which foaming resin is apply | coated to the outer surface of the said plastic container by spraying.

  The coating layer can also be formed by sticking a foamed resin plate to the surface of the plastic container, but it is preferable because the method of applying to the surface of the plastic container by spraying is simple and highly productive.

  Moreover, it does not specifically limit as a plastic container, A commercially available plastic container can be used. For example, a container made of polyethylene, polypropylene, polyethylene terephthalate, or the like can be used. The capacity is not particularly limited, but is preferably 5 L or more, more preferably 10 L or more, and further preferably 18 L or more.

  Moreover, it is preferable not to provide a coating layer on the lid surface in order to facilitate the removal of the lid, and it is more preferable to provide the coating layer in a form that does not hinder the removal of the lid.

  Of course, the portable heat insulation tank according to each of the above configurations is suitable not only for storing hot water but also for storing cold water.

  As described above, according to the present invention in which a coating layer made of foamed resin is formed on the outer surface of a plastic container, the two main components of the container and the coating layer are made of plastic, so that the two members are in close contact with each other. Since the bonding property is good and the plastic is light, a portable heat insulating tank excellent in durability, light weight, heat retaining property and heat insulating property can be realized at low cost with high productivity.

1A and 1B are diagrams showing a portable heat insulating tank according to the present invention, in which FIG. 1A is a perspective view and FIG. 1B is a cross-sectional view taken along line AA in FIG. FIG. 2 is a perspective view of a plastic container used in the portable heat insulation tank according to the present invention. FIG. 3 is a perspective view showing a coating layer manufacturing process. FIG. 4 is a perspective view showing surface leveling by a trowel.

  Embodiments of the present invention will be described below with reference to the drawings. 1A and 1B are diagrams showing a portable heat insulating tank according to the present invention, in which FIG. 1A is a perspective view and FIG. 1B is a cross-sectional view taken along line AA in FIG.

  As shown in FIGS. 1A and 1B, the portable heat insulation tank 100 includes a plastic container 10 and a coating layer 20 made of a foamed resin that covers the outer surface of the plastic container 10. The plastic container is provided with a handle 13 and two openings (not shown), and lids 11 and 12 are attached to the openings, respectively.

  Here, the coating layer 20 made of foamed resin is not provided in the vicinity of the opening, the lids 11 and 12, and the handle 13. For this reason, the main-body part of the plastic container does not appear in FIG. Moreover, since the cover layer 20 is not provided in the lid | covers 11 and 12, and the handle 13, carrying property and sealing performance do not fall. In addition, you may provide a coating layer in these. Further, the number of openings, the presence / absence of a handle, and the arrangement thereof are not particularly limited.

  Further, a thread is engraved on the outer surface of the opening, and a screw groove is engraved on the lids 11 and 12 so as to be fitted to the thread.

  The plastic container 10 is not particularly limited, and commercially available plastic containers can be widely used. The material of the plastic container 10 is not particularly limited, but preferably has heat resistance of 60 ° C. or more and cold resistance of −10 ° C. or less. For example, polyethylene terephthalate, polyethylene, polypropylene and the like can be suitably used.

  Although it does not specifically limit as foamed resin which comprises the coating layer 20, It is preferable that it has 60 degreeC or more heat resistance and -10 degreeC or less cold resistance, and is excellent in adhesiveness with the plastic container 10. FIG. For example, foamed polyurethane can be suitably used.

  Next, a method for providing the coating layer 20 on the outer surface of the plastic container 10 will be described. FIG. 2 is a perspective view of a plastic container used for a portable heat insulating tank, and FIG. 3 is a perspective view showing a coating layer manufacturing process.

  As shown in FIGS. 2 and 3, a coating layer 20 made of foamed polyurethane can be applied to the outer surface of the plastic container 10 using a foamed polyurethane spray 30. As shown in FIG. 3, the coating layer 20 is formed so as to rise from the plastic container 10 by spray coating.

  Here, the average thickness of the coating layer 20 is preferably 10 mm or more from the viewpoint of ensuring heat retention. Further, if the average thickness of the coating layer 20 is too thick, the storage property and the portability may be impaired. Therefore, the average thickness of the coating layer 20 is preferably 30 mm or less. Here, as shown in FIG.1 (b), in the case of the coating layer 20 with an unevenness | corrugation, thickness does not need to be always 10-30 mm.

  The covering layer 20 of the portable heat insulating tank 100 manufactured in this way has a structure with a large number of irregularities on the surface as shown in FIG. 1 due to uneven foaming or the like. Thereafter, as shown in FIG. 4, the surface of the coating layer 20 may be smoothed using a trowel 40. As a result, the non-normalized region 21 with many irregularities of the coating layer 20 becomes a flattened region 22 (flat with few irregularities).

  In this portable heat insulating tank 100, since the heat insulating and heat insulating action is enhanced by the coating layer 20 made of foamed resin, the liquid inside the plastic container inside the coating layer can be kept warm. Moreover, since the plastic container 10 and the coating layer 20 made of foamed resin are both lightweight, they can be easily carried even when a large amount of hot water is added. Further, since the plastic container 10 has a certain rigidity, the strength of the portable heat insulating tank 100 is maintained, and the impact resistance of the plastic container 10 can be enhanced by the coating layer 20.

  Such a portable heat insulation tank 100 can be manufactured by spraying foamed polyurethane spray on the surface of the plastic container 10, for example. That is, according to the present invention, it is possible to realize a lightweight portable heat insulating tank excellent in heat retention by a simple method.

  As described above, according to the present invention, a lightweight portable heat insulating tank excellent in heat retention can be provided. Therefore, industrial applicability is great.
