       FIELD OF TECHNOLOGY 
       [0002]    The present invention relates to a washing water spraying vessel for a nasal cavity cleaner, specifically providing a locking function by means of a one-way rotation of an outer cap, thereby completely preventing the outer cap from being pressed due to external pressure when being carried, and thus can prevent unnecessary waste of the washing water, as well as prevent contamination of the interior of an overcap. 
       BACKGROUND OF THE INVENTION 
       [0003]    Generally, washing water spraying vessels for a nasal cavity cleaner are containers for curing all kinds of the diseases in a nasal cavity or eliminating impurities, and preventing dryness by inserting washing water into the nasal cavity, and it is said that the nasal cavity comprises the front unit connected to the outside through nares, and the rear unit connected to a pharynx through a posterior nares. 
         [0004]    The washing water inserted into the above-mentioned washing water spraying vessel for a nasal cavity cleaner generally uses a 3% saline solution, and recently functional washing water containing various ingredients such as bamboo salt is being improved. 
         [0005]    In addition, lately, air pollution caused by exhaust gas from vehicles, pollen and yellow dust in the spring, and cold viruses prevailing during in-between seasons are inhaled through a mouth and a nose, thereby causing harmful materials for the human body to be deposited or various respiratory diseases and hay fever or colds to be developed with frequency; whereupon, there are an increasing number of people who suffer from snoring. 
         [0006]    It is already proved through many medical reports that washing the nasal cavity is effective for all kinds of the respiratory diseases, and patients who suffer from all kinds of the respiratory diseases wash their nasal cavity several times a day. 
         [0007]    With reference to Utility Model Registration No. 20-0165667, a conventional washing water spraying vessel for a nasal cavity cleaner is described below. Referring to the registered utility model, the conventional washing water spraying vessel for a nasal cavity cleaner comprises a container  100  receiving a cleaning liquid, a lid  200  screw-coupled in a spout portion of the container  100 , a nozzle  300  vertically movably coupled to the lid  200 , wherein a hanging part  310  for allowing vertically moving a finger to hang is formed in a lower part, a bottom liquid chamber  320  is formed in an inner top, and a spurting opening  321  for spurting the cleaning liquid in an upper part, an adjustment rod  330  inserted into the bottom liquid chamber  320  of the nozzle  300 , for uniformly and thinly spraying the cleaning liquid, and valves  550 ,  551  for spurting through the spurting opening  321  the cleansing liquid after the cleansing liquid included in the container  100  is stored in the bottom liquid chamber  310  by vertically moving the nozzle  300 . 
         [0008]    In the washing water spraying vessel for a nasal cavity cleaner consisting of the above-described configuration, it is configured that the nozzle  300  is coupled to the lid  200  of the container  100  to be upwardly slid, so that the cleansing liquid is spurted by the operation of the valves  550 ,  551  of an inner side according to repeatedly perform pressing by putting the finger in the hanging part  310 , thereby easily portable to use. 
         [0009]    However, the above-mentioned washing water spraying vessel for a nasal cavity cleaner does not have a structure that limits the movement of a latch, so that, while in the bag, though a user does not manipulate it, the latch  310  is pressed and spurts washing water. As a result, washing water can be spilled by pressing the latch  310 , and thus, not only may the content be unnecessarily consumed but the inside of the overcap may be contaminated. 
       SUMMARY OF THE INVENTION 
       [0010]    The present invention is devised to solve the above mentioned problems; the purpose of the present invention is to provide a washing water spraying vessel for a nasal cavity cleaner having a locking function by means of a one-way rotation of an outer cap, thereby completely preventing the outer cap from being pressed due to external pressure when being carried, and thus can prevent unnecessary waste of the washing water, as well as prevent contamination of the interior of an overcap. 
         [0011]    To solve the above problems, a washing water spraying vessel for a nasal cavity cleaner according to the present invention comprises: a container body wherein content are stored; an inner cap which is engaged on the inner side, covering the upper portion of the container body so as to be rotated, with a pump-blocking projection protruded on the side; an outer cap which is coupled, covering the upper portion of the inner cap, and can move upwards and downwards according to the location of the pump-blocking projection upon the rotation; a pumping member which discharges the content through pumping operation by the upward and downward movement of the outer cap; and an overcap which is coupled, covering the outer cap. 
         [0012]    In addition, the outer cap comprises: a body which is coupled, covering the upper portion of inner cap, further comprising an insertion groove, wherein a part of the lower portion is cut open and the pump-blocking projection is inserted according to the rotation; and a combining pipe which is coupled with protrusion from the center of the upper portion of the body and combined with the pumping member, pressurizing the pumping member. 
         [0013]    In addition, on the inner circumference surface is installed a pumping guide groove, wherein the pump-blocking projection is inserted. The length of the pumping guide groove should be the same or longer than the length of the pump-blocking projection so as not to cause inference with the pump-blocking projection according to the descent of the body. 
         [0014]    In addition, the pumping guide groove comprises a gentle slanting surface with one side so as not to cause interference with the pump-blocking projection when the outer cap is rotated. 
         [0015]    In addition, on the inner circumference surface of the outer cap is installed a rotation display part, which comprises a gentle slanting surface so as not to cause interference with the pump-blocking projection when the outer cap is rotated. 
         [0016]    In addition, on the outer circumference surface of the outer cap is installed a rotation display part showing the direction of rotation. 
         [0017]    In addition, on the upper portion of the inner cap is installed an engaging protrusion, which limits the ascent of the outer cap, and a protrusion is formed on the inner side of the outer cap, where the protrusion meets the engaging protrusion. 
         [0018]    As the above mentioned, according to the present invention, by providing a locking function by means of a one-way rotation of an outer cap, thereby completely preventing the outer cap from being pressed due to external pressure, the present invention thus has an advantage that it can prevent unnecessary waste of the washing water, as well as prevent contamination of the interior of an overcap.
