Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of liquid tubular container, which is a container with a very small volume, which is always sealed so as not to be altered or contaminated by contact with air when not normally used. It is a sealed container that can be stored as it is, and when it is used, the pressure in the atmosphere, capillary action and gravitational action can be used to quickly discharge the liquid in the pipe.

[0002]

[Prior art]

 Conventionally, wound treatment medicinal products contain cotton swabs and various chemicals, and in case of injury, various bottles and cans are taken out and used, which is very inconvenient. Not only are there many types of drugs, but the economic burden and storage space are widening, and it is also difficult to find a drug to apply from among various drugs. It is a waste of time. Even if some of the stored chemicals are left over, even if they are left over, they have to be thrown away after the expiration date, so there is a lot of waste, increasing the burden of environmental protection. Also, the more frequently the swab is used, the more mold bacteria in the air that adhere to the swab or infiltrate into the extra chemical solution and contaminate the chemical solution. Not only does it have no medicinal effect, but it is exacerbated by continued use. Therefore, when going out, it is inconvenient to carry many kinds of chemicals, cotton swabs, and first aid items when traveling, and it is a burden for luggage. And I'm worried about that again.

[0003]

[Problems to be solved by the device]

 However, not only first-aid items and medicines, but perfume, beverages and seasonings used in daily life experience the same inconvenience. Not only is the container large in volume and inconvenient to carry, but it is also inconvenient to take it out and use a spoon or other tool. In addition, if the liquid in the container is frequently contacted with air, it evaporates and its concentration increases, or it dries, and then it becomes contaminated or deteriorated, which is not only unsanitary but also inconvenient to use, and this is improved further. Need to be convenient.

An object of the present invention is to provide a closed simple tubular container.

[0005]

[Means for Solving the Problems]

 The closed container of the present invention is an elongated tubular container, which contains necessary liquid contents therein, has a small volume, is convenient to use, and is sanitary. Liquids that must be used at all times, such as disinfectants (iodine tincture, oxyflu, red tin, alcohol, saline solution), salves, perfumes, beverages (water, ginseng liquid) or seasonings (soy sauce, condensed milk, sugar water), etc. Fill the inside and leave both ends of the thin tubular container sealed to prevent evaporation, increase in concentration or drying of the liquid in the container and avoid contamination and deterioration due to contact with air, and In use, the ends of the tubular container only come into contact with the atmosphere, and the pressure, capillarity, and gravitational action of the atmosphere causes the liquid in the tubular container to flow out by itself, eliminating the need for a spoon or other tool. It is very practical and convenient. In addition, the tip of the liquid is covered with a suitable coating depending on the filled liquid in the tube, such as cotton (filling liquid is chemical liquid, perfume, etc.) or brush (filling liquid is soy sauce, etc.). It is convenient to use, and you don't have to prepare a cotton swab or brush separately, so it is convenient and saves time. If the filling liquid is a drink, no cover is required. In addition, the present invention has devised a structure of inner and outer tubes to reduce the volume of the tubular container and make it more convenient to use.

The present invention has the following advantages over traditional liquid containers. (1) The application range is very wide, portable and convenient to use. In addition, the characters of the contents and usage instructions can be clearly marked on the tube, which saves packaging materials and costs. (2) When not in use, the inside of the container is completely sealed, so it can be stored for a long time without contact with air or external substances, and when used, the tip of the tubular container is slightly tilted, It is very convenient and convenient because the pressure in the atmosphere, capillary action and gravitational action cause the liquid in the tubular container to flow out and there is no need to use a device such as a spoon at all.

(3) Since the manufacturing process is simple and the cost is low, and the required liquid dose is filled in the tubular container, the control of the liquid volume is convenient and there is no fear of excess or deficiency. (4) The present invention can at the same time replace traditional liquid containers, dispensing devices, application and use tools. The coating for the coating attached to the liquid outflow tip in the present invention can not only replace the traditional application and use equipment, but it can also be an absorbent such as sponge, cotton, etc., An eyebrow brush, eyelash brush, lipstick brush, eye shade stick can be used. If the liquid in the tube is to be drunk directly, no covering is required.

(5) When the present invention adopts the inner and outer tube design, the liquid filled in the inner tube does not come into contact with the outer tube, so that the material and color of the outer tube can be freely selected and there is no limitation. (6) When the present invention adopts the inner and outer pipe design, the outer pipe has a function of protection, and the liquid inside may be broken due to the pipe being broken due to unexpected collision with an object or carelessness. It is safe because it does not leak.

(7) When the present invention adopts the inner / outer tube design, the inner tube expansion / contraction design can effectively save the space. For example, it is very convenient for the dentist to use the liquid medicine filled in the inside of the present invention, instead of using the long rod having the liquid medicine applied to the tip. (8) When the present invention adopts the inner-outer pipe design, it has the functions of insurance and localization by arranging the positions of the inner pipe and the outer pipe, and when it is not used, it is possible to prevent inadvertent outflow of liquid in the pipe, and when using it, The liquid in the pipe will flow out quickly if the foldable line is easily broken.

(9) Regardless of whether the present invention is a double pipe or a single pipe, the liquid can be completely sealed in the pipe and can be stored for a long time. (10) Whether the present invention is a double pipe or single pipe design, the liquid in the pipe can be quickly discharged for application or use by a very simple operation with a connecting rod or hydraulic principle. It is very useful to be able to serve.
