Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the waterproofing of containers formed using mv containers.

The paper tube is formed by rolling it into a cylindrical shape, and is it wide and thick? You can choose freely, and you can use water-resistant tape such as synthetic resin tape for the inner and outer surfaces.1.It can be used not only as a single KWJ-shaped object but also as a container. This is possible. In particular, since the molding cost of this product is much lower than that of other cylindrical bodies, it is desired to use it as a container for consumption by large rats, such as a soft drink container. However, as mentioned above, I don't like paper tubes! Since it is molded by forming x layers, the inner layer surface and outer surface can be fully water resistant, but the cut end is extremely susceptible to water, and if water or other liquid gets into this part, it will cause damage.汓) Penetration between the layers may cause the laminated state to break or the edges to swell. Therefore, it is essential that the container be made in a manner that prevents water droplets from forming at the edges. Limited to unreasonable cases, methods have been tried, such as condensation of uJ symptoms where water is condensed in a container, or making the cut end in a format that does not expose the cut end. It was.

However, with this method, the 3fs of the container could be saved and reduced to a certain limit, so it could not be used for soft drinks or processed foods. For example, the entire cancerous area of ``A'' is immersed in VC water-resistant coating agent solution, and this area is coated with water-resistant coating agent! Cloth wrapping is another option, but most of these types of containers are easy-to-open, and the lid is glued to the top of the paper tube, which is the main body of the container, and if you pull it up with a certain amount of force, Since it can be removed by peeling, the physical conditions of the bonding surface between the two are severely restricted, especially in terms of peel strength, so coating this surface with a water-resistant thin film will meet the requirements of the bonding surface. This method cannot be used because it would exceed the limit of peel strength and the m1ei of Easy Beer would be lost.

The present invention has been made in view of the above-mentioned points, and after attaching a lid to a paper tube to form a container, a water-resistant coating 014 is applied to the cut end of the paper tube. The container is made waterproof without sacrificing any of its functions, thereby increasing the overall range of uses of the container.

The present invention will be specifically explained below based on the drawings. First, the top lid 2 is attached to the container body 1 by gluing it. Container body 1
The fall tube is formed by cutting it to a desired size, and the top lid 2 is glued to the inner circumferential surface of the end of the container body 1.

This top lid 2 is a so-called easy beer, and the contact force with the container body 1? If you pull up the knob 31rt9r provided in advance on the periphery of the upper lid 2 with the force of your foot, it will peel off and be adjusted to the extent that it can be removed. Therefore, does the adhesive have an appropriate multiplication force? Since the one with the inner layer is selected, the tape that covers the entire inner layer is polyethylene or ionomer 5 violet laminated. Take a horse,
On the other hand, the lower surface of Upper Meng 2 is fully laminated with polyethylene and ionomer 6, and the thermal heat is fully utilized to save both γ.
They fit together. Like this, jacket 2? After the container is installed, the cut end of the main body of the container will be exposed, so next apply Riko water-resistant coating mJk to this part. There are no particular limitations on the coating method. It is sufficient to coat the cut end of the paper tube to make it water resistant, and the spray coating method or dip coating method is used.
There are no particular limitations on the coating agent,
An appropriate container is selected depending on the purpose of the container.
For example, when the content is food or drink, polyvinylidene is used. The above-mentioned coating can be performed not only when the upper lid 2 is attached to the container body 1, but also after the container Vζ is filled with the contents and the lower lid 4 is attached. In this way, when the water-resistant coating agent is applied, since the container body l and the upper chamber 2 are already joined,
The Easy Beer function of Kamiyuki 2 is added to the casing that retains this function and is water resistant. In particular, if the coating agent has been disintegrated by the dipping method,
Even if there is a weak joint between the container body 1 and the top lid 2, and there is a slight gap between the two, the coating agent will enter this gap and cause all the light to disappear, so the container will not be covered with paper. This not only ensures the water resistance of the cut FfT end of the tube, but also ensures the airtightness of other parts.

As described in detail above, the present invention is a container body formed by cutting an m-tube, and a top lid that is completely easy-to-beer. The paper tube is glued together and then coated on the cut end of the paper tube,
Since the container is water-resistant without impairing the functionality of Easy Beer, it can be widely used as a prize or other container for beer.

[Brief explanation of drawings]

The figure is an example of a container that was completely destroyed in the 6th century.

Claims (1)

[Claims] Cut the entire paper tube into appropriate dimensions to make the container body, and cut the entire paper tube into the upper end of the container body. A method for manufacturing an easy beer container, characterized by attaching the top cover to the TJ side with the whole surface covered, and then applying a water-resistant coating agent F to the cut end of the paper tube to impart water resistance to the cut end.
