Description

Technology Field

[0001] The present invention relates to a structure for installing a hygienic inner liner for a military canteen, and more specifically, to a structure for installing a hygienic inner liner for a military canteen that protects drinking water from unhygienic contamination of the canteen that may occur when multiple users use it for a long time by applying the inner liner to the existing supply canteen currently in use by the military. Background Technology

[0002] Liners currently used in the semiconductor and display industries are products used to simultaneously prevent contamination of high-purity chemical solutions contained inside storage containers and the containers themselves. In the industry, they are applied to containers ranging from several liters to 200 liters, and they contribute to maintaining the quality of distributed chemical products and reducing container replacement costs by preventing contamination of high-purity chemical solutions and extending the lifespan of stainless steel containers.

[0003] The liner is primarily made of materials with excellent chemical resistance, such as Teflon or polyethylene, and a high-purity chemical solution is injected into the liner after inserting it into a stainless steel container for transport and attaching a nozzle.

[0004] When injecting a chemical solution into the liner, an air layer exists between the container and the liner. Since this interferes with the buffering of the chemical solution, the connector located at the top is connected to a vacuum pump to remove the air simultaneously with the solution injection process.

[0005] In the chemical solution usage state, the internal chemical solution is used by squeezing the liner through air injected into the connector where the vacuum pump was connected, and a process pipe is connected to the inlet nozzle.

[0006] After using the chemical solution, open the container lid and remove the thinned liner.

[0007] If an inner lining structure, which is housed within an outer container such as a liner of a conventional chemical container, can be manufactured as a water bag installed inside the container and applied to the ROK Armed Forces' canteens, it is possible to protect drinking water from unsanitary contamination that may occur when multiple users use the canteen for a long period, thereby allowing soldiers to drink more hygienic and safe drinking water, as well as reduce the defense budget by extending the lifespan of the supplied canteens.

[0008] Canteens supplied by the ROK Armed Forces using conventional technology utilize products of at least two different specifications, and there is a problem in that the opening of the canteen widens due to long-term use. Therefore, although there is a need to design and manufacture a water pouch applicable to all supplied canteens to meet these various conditions, such a structure has not been developed in the past.

[0009] In addition, while air between the container and the liner can be removed using a vacuum pump in the case of liners according to conventional technology, a separate structure is required to remove air from inside the canteen because the method of connecting a vacuum pump cannot be applied since the canteens supplied to the ROK Armed Forces are used in the field.

[0010] Furthermore, in conventional technology, components connected to the liner were applied as single-use items to maintain the purity of high-purity chemical solutions; however, for environmental protection, the water bag according to the present invention needs to be configured to be semi-permanently usable by replacing only the water bag. Additionally, it needs to be designed and manufactured so that military personnel can easily replace and use the water bag even in extreme environments such as training and combat, but technology to satisfy these needs has not been developed. The problem to be solved

[0011] The present invention was devised to solve the problems of the prior art, and more specifically, it aims to provide a structure for installing a hygienic inner liner for military canteens that protects drinking water from unsanitary contamination that may occur when multiple users use the canteen for a long time by applying an inner liner to the existing supply canteens currently in use by the military, thereby enabling soldiers to drink more hygienic and safe drinking water and reducing the national defense budget by extending the lifespan of the supply canteens. means of solving the problem

[0012] The hygienic inner liner installation structure for a Korean military canteen according to the present invention, for achieving the above-mentioned purpose, comprises: a water pouch made of a material having a size and shape corresponding to the internal size and shape of the canteen, rolled into a cylindrical shape, and inserted into the canteen through the canteen inlet, and including a spout portion having an inlet / outlet hole formed therein for water to enter and exit; a fixing ring having a female screw portion formed on its inner surface and capable of surrounding the spout portion of the water pouch; and an injection tube having a hollow tube shape and comprising an upper fixing portion and a lower insertion portion, wherein the fixing portion has a locking projection protruding outwardly so that its upper end can rest over the canteen inlet, and a plurality of ribs are formed protruding at intervals along the outer surface of the fixing portion to support the locking projection from below on the upper outer surface of the fixing portion, and the insertion portion is a part inserted into the spout portion of the water pouch through the inlet / outlet hole of the water pouch, and is configured such that a male screw portion corresponding to the female screw portion of the fixing ring is formed on the upper outer surface of the insertion portion.

[0013] In addition, it is preferable that the above-mentioned stopper has a plurality of pinholes formed therein that penetrate in the vertical direction to allow air between the water bag and the water container to escape to the outside.

[0014] In addition, it is preferable that the pinhole be formed with a double structure in which the diameter of the lower part is larger than the diameter of the upper part.

[0015] In addition, it is desirable that the ribs have a beveled edge shape as the length of the outward protrusion decreases from top to bottom.

[0016] In addition, it is preferable that the material of the above water bag be polyethylene. Effects of the invention

[0017] As described above, the hygienic inner lining installation structure for military canteens according to the present invention has the advantage that military personnel can drink clean water when using supply canteens in situations such as training or combat, thereby preventing diarrheal and vomiting-type food poisoning, endocarditis, sepsis, and purulent diseases that may occur due to infection with Bacillus cereus.

[0018] In addition, the present invention has the advantage of fundamentally resolving the negative image of the armed forces caused by unsanitary canteens through technical improvements.

[0019] In addition, according to the present invention, trainees can use canteens to conduct more realistic training, and military personnel can secure their own drinking water in wartime situations, thereby enabling effective operation execution.

[0020] In addition, according to the present invention, the water bottle can be restored to its original drinking water use even after being used for various purposes such as transporting oil or medicine, and has the advantage of being useful even in extreme environments such as combat and operations due to the portability and ease of use of the water bottle.

[0021] In addition, according to the present invention, the lifespan of supply canteens is extended, contributing to long-term savings in the national defense budget, and recyclable polyethylene is used as a material, thereby contributing to resource management and environmental protection.

Specific details for implementing the invention

[0023] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the attached drawings.

[0024] The hygienic inner lining installation structure for a military water canteen according to the present invention comprises a water pouch (100), a fixing ring (200), and an injection tube (300).

[0025] The water pouch (100) has a size and shape corresponding to the size and shape of the inside of the water container (10) as shown in FIG. 2, and when filled with water, it acts as the inner lining of the water container inside the water container (10).

[0026] The spout (110) located at the center of the upper part of the water pouch (100) is a part installed inside the spout portion of the water container (10), and an opening is formed at the top of the spout (110) through which water can enter and exit.

[0027] The water bag (100) is made using only one raw material, recyclable polyethylene, so it contributes to resource management and environmental protection.

[0028] The water bag (100) is in the form of a vinyl bag made of 0.05 mm polyethylene film and is heat-sealed to fit the internal shape of the supply water bottle, so that no leakage occurs and the capacity of the water bottle can be maximized.

[0029] The water bag (100) is made of a flexible material so that it can be rolled up or folded into a cylindrical shape and the water bag (100) can be inserted into the water bottle through the inlet (11) of the water bottle.

[0030] The fixing ring (200) is a circular ring-shaped member with a female screw portion (210) formed on its inner surface, and is a member that surrounds the spout portion (110) of the water bag (100) when installation is complete.

[0031] The fixing ring (200) is intended to allow the water bag (100) to be easily replaced and used. The fixing ring (200) is configured in a screw-fastening manner so that the injection tube (300) and the water bag (100) can be easily fixed without adhesive, and the product according to the present invention is designed so that no noise is generated during mounting and detachment.

[0032] The injection tube (300) has a hollow pipe shape and is configured to include an upper fixing part (310) and a lower insertion part (320).

[0033] The injection tube (300) is manufactured to allow air to be discharged smoothly by forming four double-structured pinholes to discharge air between the inside of the water container and the water bag where a vacuum pump cannot be used.

[0034] The fixing part (310) is provided with a stopper (311) that protrudes further outward than other parts of the injection tube (300) by bending the upper part outward so that the upper part can be placed over the injection port (11) of the water bottle.

[0035] The injection tube (300) includes six ribs (312) that act as springs when the injection tube (300) is fixed, so that it can be applied to supply canteens of various sizes other than the same size.

[0036] The new water bottle has a double lid structure, and the maximum diameter of the primary inlet is 48 mm, and the diameter of the secondary inlet for actual use is approximately 23.5 mm.

[0037] In the case of old water bottles, the diameter of the opening is about 25 mm, but due to prolonged use, the opening is worn down and the diameter often increases, so the average diameter is about 25.4 mm as a result of actual measurements.

[0038] The capacity of the water bottle (10) is about 1000ml for the new model and about 920ml for the old model.

[0039] In addition, the six ribs (312) provided in the injection tube (300) ensure sufficient space between the injection port (11) of the water bottle and the injection tube (300), allowing air between the inside of the water bottle (10) and the water bag (100) to be smoothly discharged.

[0040] A rib (312) that supports the catch (311) from below is integrally formed on the upper outer surface of the fixed part (310), and the rib (312) has a structure in which six ribs are formed protruding outward at intervals along the outer surface of the fixed part (310).

[0041] The rib (312) is formed in a slanted shape such that the length of the outward protrusion decreases as it goes from top to bottom, and the edges come together towards the center of the fixed part (310) as they come from top to bottom.

[0042] The six ribs (312) are intended to allow the injection tube (300) to be tightly fitted and fixed even if the inner diameter of the spout portion of the water bottle (10) is different, thereby enabling the invention to be applied to various types of supply water bottles, and also serve the role of allowing air to escape through the space between the ribs (312). The air that escapes through the space between the ribs (312) is discharged to the outside through the pinhole (313) of the stopper (311).

[0043] Four pinholes (313) are formed at regular intervals in the catch (311) so that they penetrate in the vertical direction and allow air between the water bag (100) and the water container (10) to escape to the outside.

[0044] As illustrated in FIG. 4, the pinhole (313) is formed with a double structure in which the upper diameter is several times larger than the lower diameter, and while the upper diameter of the pinhole (313) is constant, the lower diameter of the pinhole (313) gradually widens as it goes downward. This structure facilitates air discharge, prevents the introduction of foreign substances by blocking the narrow outer hole due to a water film phenomenon when water is injected, and is configured to block the inflow of foreign substances between the water pouch (100) and the water container (10) when drinking water.

[0045] The insertion part (320) is connected below the fixing part (310) of the injection tube (300) and is a part that is inserted into the mouth part (110) of the water bag (100) through the entrance / exit hole of the water bag (100). On the upper outer surface of the insertion part (320), a male screw part (321) corresponding to the female screw part (210) of the fixing ring (200) is formed.

[0046] The operation of the hygienic inner lining installation structure for a military canteen according to the present invention, configured as described above, is as follows.

[0047] First, as shown in FIG. 6, the water bag (100) is rolled up, and then the end of the water bag (100) with the spout is passed through the fixing ring (200) so that the water bag (100) is fitted into the fixing ring (200).

[0048] Then, the insertion part (320) of the injection tube (300) is inserted into the mouth part (110) of the water bag (100).

[0049] Then, by pulling the fixing ring (200) toward the injection tube (300) and rotating it so that the female threaded portion (210) of the fixing ring (200) and the male threaded portion (321) of the injection tube (300) are connected to each other, the injection tube (300) and the fixing ring (200) are fixed to each other, and the spout portion (110) of the water bag (100) that was between them is also fitted and fixed between them.

[0050] Then, as shown in FIG. 7, the water bag (100) is folded in a zigzag pattern to make it smaller, and as shown in FIG. 8, the water bag (100) is placed inside a prepared water bottle, and the injection tube (300) is inserted into the injection port (11) of the water bottle (10), thereby firmly securing the injection tube (300) to the water bottle (10) by means of six ribs (312) and a stopper (311). The present invention is designed so that when the water bag (100) is inserted into the water bottle (10), the six ribs (312) are arranged to easily settle in the correct position, thereby making it applicable to supply water bottles of various sizes, and by implementing a screw fastening structure, the assembly of the water bag (100) is easy, and it is designed so that problems such as falling off, leakage, or tearing do not occur during use.

[0051] After the injection tube (300) is fixed, the water container is gently shaken while injecting water so that the water bag (100) expands well inside, and the volume of the water bag (100) naturally expands, and as a result, the air inside the water container (10) is discharged through the four pinholes (312) formed at the top of the injection tube (300), thereby ensuring sufficient capacity inside the water container (10).

[0052] The air existing between the inside of the water container (10) and the water bag (100) is expelled to the outside, thereby regulating the internal pressure during the water injection process and preventing the water bag from expanding. Additionally, when water is injected, a water film phenomenon occurs in the relatively small outer hole among the pinholes (312), preventing external air or contaminants from penetrating into the inside of the water container (10), so that the water remains safe and clean. This is an important design element for enhancing user hygiene and convenience.

[0053] After inserting the water bag (100) into the injection tube (300) and assembling it by turning the fixing ring (200), it can withstand a weight of at least 2 kg, thereby stably fixing the inner lining of the sanitary water bottle to prevent leakage due to breakage and providing strong durability to withstand the weight of water from vigorous physical activity.

[0054] As described above, the present invention has been described only with respect to preferred specific examples; however, it is obvious to those skilled in the art that various modifications and variations are possible within the scope of the technical spirit of the present invention based on the above specific examples, and it is also natural that such modifications and variations fall within the scope of the appended claims.
