Field of the Invention The present invention relates to a thermos bottle in which a decorative film on which a character, a trade name, a product name, and the like is printed on a surface of a stainless steel vacuum thermos outer cylinder is bonded, and a method of manufacturing the same.

In general, a stainless steel vacuum thermos is composed of an inner cylinder, an outer cylinder, and a stopper to insulate the contents, so as to maintain the vacuum space between the inner cylinder and the outer cylinder.

In addition, the shape of the thermos outer cylinder is made of a variety of forms, such as a cylinder forming a straight line and curved surface in the longitudinal direction, or a angular cylinder forming a circumference, these are made of a narrow diameter to be opened and closed by injecting a beverage on the top. In order to form the thermos as described above, the cylindrical material is formed by a bulging operation for enlarging a portion excluding the opening and formed by inner tube welding. And stickers may not be attached in advance.Always, after the product is completed, the company name, brand name (symbol mark) and pictures, figures, characters, etc. suitable for the user's age may be printed directly on the surface of the outer cylinder, or attachments such as stickers may be used. It must be attached.

However, since the ink printed and attached stickers on the outer tube of the thermos are protruded from the surface, they are easily discolored and peeled off during use, and they are easily peeled off when heated for the characteristics and disinfection of the stainless material, resulting in loss of product value. As a result, the propaganda effect of the product is lowered and the seller's credit is lowered.

Due to the above problems, the outer cylinder of the currently sold stainless metal thermos is reluctant to attach a separate printing and stickers. Because of this, the conventional thermos will only display gray inherent in the cylindrical stainless material, there is a problem that does not easily recognize the seller's products to the consumer, and easily get tired.

The present invention was devised to solve the conventional problems as described above, the object of the present invention is a decorative hard film printed with the desired company name, brand name (symbol mark), pictures, figures, characters, etc. on the surface of the thermos outer cylinder By attaching the aesthetics to enhance the aesthetics of the appearance to be curious, to accurately deliver the source of the product to the consumer, and to differentiate the product value with other companies and enhance the competitiveness.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the method of manufacturing a thermos bottle bonded with a decorative film of the present invention will be described with reference to FIGS. 2 to 4. The high-temperature hard synthetic resin decorative film (1) and a molding and vacuum The finished stainless metal thermos 2 is prepared.

The decorative film 1 used in the present embodiment may use a brand name M87B8 or M9106 of LG Chem, which is a polyester resin film, and a thickness of 0.3 to 0.5 mm, but a resin having a high heat resistance may be used. .

In addition, the adhesive applied for attaching the decorative film 1 to the thermos 2 is used a conventional thermosetting adhesive composed of 70 to 90% by weight of polyester resin and 10 to 30% by weight of amino resin.

The prepared film 1 and the thermos 2 are preheated to a temperature of 180 to 250 ° C. while being kept in a normal thermal chamber to maintain the temperature.

The film 1 and the thermos 2 stored in the thermal chamber are preferably maintained at a temperature in the process of moving to the bonding process, and after the thermosetting adhesive is applied to the upper portion of the film 1 during the bonding process, the bonding process is performed. It is moved to the standby position of the thermos (2) is immediately moved to the standby position of the bonding process.

0.5-5.0 g / m <2> is suitable for the application amount of an adhesive agent, Preferably it is good to use in 1.0-2.5 g / m <2> range. In other words, when the coating amount is 0.5 g / m 2 or less, it is difficult to apply the film 1 evenly, and on the contrary, when the coating amount is excessive, the adhesive strength is remarkably lowered.

In the state where the film 1 with the adhesive applied to the upper portion and the thermos 1 are transferred to the standby position of the bonding apparatus 3 of FIG. 3, the thermos 2 is first placed on the roller 31 and then the film. (1) is pushed between the roller 31 and the outer cylinder 2 'of the thermos 2. When the roller 31 is rotated in the above state, the film 1 is attached to the circumference of the thermos 2 outer cylinder 2 'by the adhesive applied on the upper portion of the film 1. In the bonding process, it is preferable to perform thermal compression while maintaining a temperature of 180 to 250 ° C., and is adhered while being closely adhered by the compression of the roller 31 disposed on the upper portion.

In the bonding process, when the outer cylinder of the thermos 2 is formed with the same diameter as in the embodiment of FIG. 1, the film 1 is naturally sucked and attached when the thermos 2 are rotated by the pressing force of the roller 31. The method is used.

When the film 1 is to be attached up to this time, since the outer cylinder 2 'is not a garden in the bonding process, the occurrence of wrinkles due to the change in the length of the film 1 adhered to the outer cylinder 2' is prevented. In order to pull the back of the film (1) to the cylinder device 32 in order to increase the thickness of the film (1) by about 10 to 20% so as to be in close contact and finely thermally compressed.

In the above process, the film 1 bonded around the outer cylinder 2 'of the thermos 2 has a state where the start line and the end line overlap each other with a width of 0.5-1,5 cm, and the bent portion of the upper and lower outer cylinders has a width of about 0.3-0.8 mm. The work is completed in the bonded state while wrapping.

As soon as the bonding process of the film 1 is completed, the thermostable 2 is slowly cooled while transferring, and the thermostable thermos 2 is attached to the outer cylinder 2 'as shown in FIG. 4 before the adhesive is completely cured. The overlapped portions of the film 1 are cut in the vertical direction to precisely treat the seam cutting lines 11, and then the bent portion cutting lines 11 ′ of the upper and lower portions of the outer cylinder 2 ′ of the insulating tube 2 are removed. After cutting, the unnecessary cut film is removed to perform the final process of finishing.

The thermal insulation container (2) completed through the manufacturing process is a decorative hard film (2) is bonded to the surface from the lower end of the outer cylinder (2 ') to the neck of the upper portion to form a cutting cut line (11) in any part of the vertical direction The upper and lower portions of the bonded film 1 are formed to cover up to the upper and lower bent portions of the outer cylinder 2 'or to the bent extensions, and the film 1 bonded by the high temperature thermal bonding process is cut for disinfection. There is no peeling and discoloration even if put into water, and it is possible to increase the merchandise value by providing various characters, trade names, product names, etc. printed on the surface of the film 1, as well as providing decorative effects Suitable for portable thermos.

In addition, when the upper and lower portions of the film 1 bonded to the thermos 2 wrap around the upper and lower bent portions of the outer cylinder 2 ', the upper end is not exposed by the bottom of the lid 4, and the lower side is shown in FIG. As shown in FIG. 5, the lower cover 5 is shrunk or wrapped around the bottom of the lower cover 5.

In addition, since the lid 4 is mainly manufactured by injection molding of synthetic resin, it is more productive if the outside is formed to harmonize with each other by performing coloring or transfer printing to match the design and color of the film 1 of the present invention. It can increase the value.

In addition, in the above embodiment, the decorative film is attached to the thermos, but the present invention is not limited thereto, and the decorative film may be adhered to the periphery of a conventional product such as a thermostable and a mug formed of stainless metal.
