Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a tube container in which only the upper part of the tube container is wrapped, thereby simplifying packaging and saving resources.

(Prior art and its problems) Among the well-known tube containers, tube containers that are sold naked are not used until the tube container is filled with the contents, or until the tube containers are filled with the contents. By the time the tube was released, it had the disadvantage that the cap would come off, and the tube opening would become dirty and unsanitary as dust would accumulate on the tube opening. For this reason, most tube containers are sold after being filled with contents and then placed in a packaging box. However, if a tube container is sold in a packaging box, the cap will not come off after packaging and the mouth part will become dirty. However, when a consumer purchases a packaging tube and uses it, the packaging box becomes unnecessary and is discarded as garbage.

[Structure of the idea]

(Means for Solving the Problems) Therefore, this invention was developed by studying the shortcomings of bare tube containers and wrapped tube containers, and devising ways to improve them. This led to the devising of a tube container in which the body above the mouth has a lid that can be opened and closed or cut off.

(Function) The tube body also serves as a packaging, and the tube body extends upward from the mouth to serve as a lid, and the lid is broken and cut off near the shoulder.

(Example) Next, the structure of the tube container of the present invention will be explained with reference to the drawings of the example. Reference numeral 1 is a tube body that is flexible enough to be crushed with fingers, and the body 1 is made of a single layered synthetic resin body 2A. or a laminate 2B having a synthetic resin film 2b or a synthetic resin layer 2b on at least the inner and outer surfaces, and an upper cover 3 is provided at the upper end of the body 1, and a lower cover 4 is provided at the lower end; The lower end of part 1 can be heat-sealed after filling with contents.

5 is a perforation hole drilled in the upper part of the former body part 1,
The perforation holes 5 are made so as to go around the body 1 once,
The upper part of the perforation hole 5 is made into a lid part 6 that can be cut off, or the part of the body part 1 is left with a part of the body part 1 and the perforation hole 5 is bored around it, and the upper part of the body part 1 is made into a lid part 6 that can be opened and closed. It is. Reference numeral 7 denotes a tube opening provided in the body 1 below the protruding position of the perforation hole 5;
has a neck 9 above the center of the shoulder 8, is made of the same or similar synthetic resin as the body 1, and may have an air impermeable material 17 within its thickness; is adhered or heat-sealed to the upper inner surface layer 2b of the body 1, or the mouth 7 is provided by injection molding within the body 1, and the cap 10 is removably fitted into the neck 9 of the mouth 7. They fit together or screw together.

Since the tube container of the present invention has the above-mentioned structure, the monolayer 2 is attached to the synthetic resin forming the tube body 1 in advance.
A, or at least the upper part of the laminate 2B having the synthetic resin layer 2b on the inner and outer surfaces, is provided with perforation holes 5. First, the monolayer 2A or the laminate 2B with the perforation holes 5 is used to create a tube. A body part 1 is formed, and by forming the body part 1, an area above the perforation hole 5 is formed into a lid part 6 which can be opened and closed or cut off, and then a lid part 6 is formed below the perforation hole 5 from the position where the perforation hole 5 is formed. body inner layer 2
b, the shoulder part 8 of the mouth part 7 manufactured separately from the body part 1 is attached using adhesive S, and the inner surface layer 2b of the body part 1 is attached.
The shoulder part 8 of the mouth part 7 is heat-fused, or the mouth part 7 is provided by injection molding inside the body part 1, and this mouth part 7 is
The cap 10 is fitted onto the neck 9 of the body 1, and the upper lid 3 of the lid 6 extending upward from the body 1 is closed. Container manufacturers manufacture even the tube containers that are packaged by 6. The tube container of the present invention manufactured by the above-mentioned method is shipped to a product manufacturer with the tube opening 7 wrapped with the lid 6, and at the product manufacturer, the lower end of the tube body 1 which is open is opened. After filling the inside with the contents, the lower end of the body 1 is closed and sold.

When a consumer purchases the tube container of the present invention filled with contents and uses it, first, the perforation hole 5 provided between the tube body 1 and the lid 6 continuous thereto is broken, and the perforation hole 5 in the body 1 is cut. Either cut off the continuous lid part 6 from the body part 1 and throw away the cut-off lid part 6, or
After breaking the lid part 6 so that it is partially continuous with the body part 1 and swinging the lid part 6 to the continuous side to expose the mouth part 7 to the outside, the mouth part 7 is broken as in the conventional tube. In use, the cap 10 is removed and the body 1 is pressed to extrude the contents from the mouth 7.

In addition, in the specific implementation of the invention, the means for attaching the opening 7 to the tube body 1, the means for closing the upper and lower ends of the body 1, etc. are not limited to the above embodiments, and the tube body 1, the perforation hole 5 formed in the upper part of the body part 1, the opening part 7 provided in the body part 1, and the specific shape and structure of the lid part 6 which is continuous to the upper part of the body part 1 through the perforation hole 5, etc., are as follows. Changes may be made as appropriate as long as they do not violate the gist of the invention.

[Effect of idea]

Therefore, in the tube container of the present invention, only the mouth of the tube is packaged with a lid that is continuous with the body. Therefore, it is possible to significantly save the materials used for packaging compared to packaging the entire tube, and it not only helps in saving resources, but also because the packaging part that is unnecessary when using the contents filled in the tube container is small. The amount of garbage will also be reduced. Moreover, in the tube container of the present invention, a part of the body of the tube is used to form a lid during the manufacturing process of the container, and the mouth part fitted with the cap is wrapped by the lid continuous to the body. This prevents the cap from loosening or becoming dislodged during transport or transport of the tube to the filling station or during filling. As a result, it is possible to omit the process of tightening the cap before filling the contents, and also to omit the process of packing the tube into a packaging box after filling the contents. Because it can be formed by simply drilling a hole and providing a tube opening in the body below the perforation hole, it is much easier to manufacture than a fully wrapped tube container, and it maintains the same level of hygiene as a fully wrapped tube container. However, the tube container of the present invention can be provided at a low cost, and has a remarkable practical effect.
