## Background
CROSS-REFERENCE TO RELATED APPLICATION(S)
This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Dec. 14, 2012 in the Korean Intellectual Property Office and assigned Serial No. 10-2012-0146356, the entire disclosure of which is hereby incorporated by reference.
TECHNICAL FIELD
The present disclosure relates to a portable self-defense spray capable of protecting a person from danger under an emergency situation. More particularly, the present disclosure relates to a structure of spraying CN solution by compressive force, in which a compact case can be manufactured in various designs by using a filling tube including a silicon material and the CN solution can be sprayed in any direction based on compressive spraying resulting from vacuum.
BACKGROUND
Recently, when a person is in danger such as kidnapping and robbery, the person has reported the danger to the policy by using a cellular phone carried by the person. However, when the danger is reported by using the cellular phone, the person cannot rapidly manipulate the cellular phone for the report of the danger to the policy, and cannot rapidly cope with the danger to be personally applied to the person. In addition, the person has no countermeasure against the danger to be applied until the policy reaches the site after the police has been reported and dispatched.
The dangerous situation more seriously happens to women, which are more easily exposed to crimes, than men.
Accordingly, many portable self-protection articles have been provided. Among them, a self-defense spray has been mainly used to rapidly cope with the dangerous situation due to a small size, portability, and simple operation.
The self-defense spray has a structure of spraying CN solution, which is received in a receiving part provided in a case, to a spray port through an introduction tube, which is provided perpendicularly to the receiving part, as a button is pressed.
However, the self-defense spray has following disadvantages. Since most introduction tubes are separated from a bottom surface to some degree without completely making contact with the bottom surface in order to smoothly introduce the CN solution received in the receiving part, the CN solution remains on the bottom surface. In addition, when the spray is inclined for use, the CN solution is not smoothly introduced into the filling tube provided perpendicularly to the receiving part, so that the spray is not actually used.
Therefore, according to Korean Patent Registration No. 10-1078154 registered after being applied by an applicant of the present disclosure in order to improve the above problem, a case provided at the front portion thereof with a spray port includes a storage vessel filled with CN solution and having a rubber packing and the spray port having a vacuum pump operating member, so that the CN solution may be sprayed in any direction through a vacuum pump scheme if a press member is pressed.
However, since the case has a structure in which the storage vessel to receive the CN solution and the vacuum pump operating member are aligned in line with the spray port, the shapes of the self-defense spray are not various, but limited and crude, so that the user has resistance against the use of the spray.
The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.
SUMMARY
Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a self-defense spray which can be manufactured in various designs in compact size and can be sprayed received CN solution in any direction without residual CN solution.
According to an aspect of the present disclosure, a filling tube having a long length and including a flexible material such as silicon or a rubber material so that the filling tube is freely bent to receive CN solution in a case is guided so that the filling tube is not twisted. A vacuum pump operating member is installed at one side of the filling tube to spray the CN solution based on compression resulting from the vacuum pump as a button member having a spray port is pressed, and a filling cap is provided at an opposite side of the filling tube for the purpose of filling the CN solution. Accordingly, if the button is pressed, the filling tube is compressed through the vacuum pump operation, so that the filled CN solution is sprayed through the spray port.
According to another aspect of the present disclosure, when a coil spring is installed in the filling tube to guide the filling tube so that the filling tube is not twisted in the case, the filling tube is prevented from being bent, so that the filled CN solution is smoothly sprayed.
According to another aspect of the present disclosure, the CN solution is filled in the filling tube and sprayed through a compressive scheme, so that the CN solution can be sprayed in any direction of up, down, left and right and the filled CN solution can be sprayed without the residual amount. Accordingly, the waste of the CN solution can be reduced. In addition, the self-defense spray can be designed in a compact size and various shapes, so that the product quality can be improved and the incompatibility can be reduced. Accordingly, the product value can be raised.

Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.
It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.
Referring to FIGS. 1 to 5, in a self-defense spray according to various embodiments of the present disclosure, a filling tube 30, which is filled with CN solution and includes a long tube, is installed in a case 10 prepared as a separable assembly, a vacuum pump operating member 20 cooperating with a button member 40 having a spray port 41 is installed at one side of the filling tube 30, and a cap 50 is installed at an opposite side of the filling tube 30 so that the cap 50 is sealed. Accordingly, a vacuum state is formed through a pressing operation of the button member 40 so that the filling tube 30 is compressed by compressive force to make the filled CN solution sprayed.
In this case, the filling tube 30 includes a flexible material such as rubber or silicon, so that the filling tube 30 may be freely bent. The filling tube 30 has a long tube so that the CN solution is sufficiently filled therein. The filling tube 30 includes a rubber material or a silicon material so that the filling tube 30 may be freely bent. Accordingly, the self-defense spray may be manufactured in various shapes in compact size so that the self-defense spray may be portable.
FIG. 6 is a perspective view showing a cap fitted around a spray port according to an embodiment of the present disclosure, FIG. 7 is a sectional view showing another structure of a self-defense spray according to an embodiment of the present disclosure, FIG. 8 is a sectional view showing a self-defense spray according to an embodiment of the present disclosure, and FIG. 9 is a sectional view showing a self-defense spray based on a compression spray scheme according to an embodiment of the present disclosure.
Meanwhile, in order to prevent the filling tube 30 having the CN solution therein with a sufficiently long length from being twisted in the compact case 10, a protrusion part 11 is formed at a bending portion of the filling tube 30, so that the protrusion part 11 guides the filling tube 30 to prevent the filling tube 30 from being twisted.
In addition, in order to prevent the filling tube 30 from being clogged as the filling tube 30 is guided by the protrusion part 11 and bent, a coil spring 31 is provided in a portion of the filling tube 30 positioned corresponding to the protrusion part 11 and bent, so that the filled CN solution may be smoothly sprayed.
In this case, the vacuum pump operating member 20, which is installed at one side of the filling tube 30 to form a vacuum state, comprises a tube perforated at the center thereof, is provided at an inner upper portion thereof with a fixing tube 29 and at a lower portion thereof with an introduction tube 27. A supply tube 22 having a supply passage 23 communicating with an introduction hole 23a formed through a lower portion of the fixing tube 29 is axially installed in at the center of the fixing tube 29 so that the CN solution is supplied to the spray port 41 formed in the button member 40. An operating tube 21 is installed at a portion of the supply tube 22 in which the supply passage 23 is formed. The operating tube 21 is positioned at the upper portion of the vacuum pump operating member 20. A spring 26 is interposed between the operating tube 21 and the vacuum pump operating member 20 so that the button member 40 may be repeatedly pressed.
The supply tube 22, which is axially formed at the center of the fixing tube 29, includes a locking rim 24 which is formed at a lower end having the introduction hole 23a communicating with the supply passage 23 to tightly make contact with the inner wall surface of the vacuum pump operating member 20 and provided at an outer circumferential surface thereof with grooves 24a spaced apart from each other by a predetermined interval. The locking frame 24 is provided at the lower end thereof with a guide rod 25 fitted into the center of the introduction tube 27 formed at the lower portion of the vacuum pump operating member 20 to perform a guide operation, so that the supply tube 22 may perform a stable pumping operation. A packing 28 is positioned between the upper portion of the locking rim 24 and the fixing tube 29 so that the introduction hole 23a communicating with the supply passage 23 is sealed. Accordingly, if the button member 40 is pressed, vacuum is formed in the supply tube 22 so that the packing 28 is fixed by the vacuum while the sealed introduction hole 23a is open. Accordingly, the filling tube 30 is compressed due to the vacuum so that the CN solution is sprayed.
In this case, the packing 28 for sealing, the supply tube 22, and the introduction tube 27 may be installed inside the vacuum pump operating member 20 by the fixing tube 29 installed at the inner upper portion of the vacuum pump operating member 20. After the introduction tube 27, the supply tube 22, and the packing 28 are sequentially installed in the vacuum pump operating member 20 including a tube, the fixing tube 29 is axially installed in the supply tube 22, so that the fixing tube 29 is fixedly coupled with the vacuum pump operating member 20.
Therefore, if the button member 40 is pressed, the operating tube 21 cooperating with the button member 40 pumps up and down by the elastic of the spring 26 above the vacuum pump operating member 20. In this case, when the button member 40 is pressed, the operating tube 21 is pressed while the supply tube 22 axially installed in the fixing tube 29 is pressed, so that the pumping operation may be performed.
In addition, an inclined surface 24b is formed on a top surface of the locking rim 24 formed under the introduction hole 23a communicating with the upward-protruding supply passage 23 of the supply tube 223, and an inclined surface the same as the inclines surface 24b is formed at the inner wall of the packing 28 positioned at the top surface of the locking rim 24 and fitted to seal the introduction hole 23a. Therefore, as the supply tube 22 is pressed by the button member 40, the pumping operation is performed so that a vacuum pressure is generated. In this case, the packing 28, which is in the floating state, is stopped. In this case, as the supply tube 22 is more pressed, the inclined surface 24b is spaced apart from the corresponding inclined surface of the packing 28 which is engaged with the inclined surface. In this case, the introduction hole 23a is open so that the CN solution is introduced into the supply passage 23.
In this case, the CN solution may be filled in the filling tube 30, so that the filling tube 30 may be re-used several times.
To this end, if it is determined that the CN solution is completely exhausted by separating the cap 50 installed at an opposite side of the filling tube 30 to clog the opposite side of the filling tube 30, the opposite side of the filling tube 30 having no cap 50 is inserted into an additional container to receive the CN solution and a pumping operation is performed by consecutively pressing the button member 40. In this case, vacuum is generated from the vacuum pump operating member 20, so that the CN solution received in the additional container is automatically sucked into the filling tube 30 by the compressive force, so the filling tube is filled with the CN solution.
Further, in order to fill the CN solution in the state that the cap 50 is not separated, the cap (50) includes a tube having the form of a through hole, and has one side formed therein with a coupling tube 50a communicating with the filling tube 30 and an opposite side formed at an inner wall surface thereof with a thread so that a fastening member 51 having a thread is screwed with the inner wall surface from the outside to seal and finish the cap 50. Accordingly, as the fastening member 51 is open/closed through the screw-fastening scheme, the CN solution can be easily filled.
In addition, a fluid passage hole may be formed in one side of the fastening member 51, and the fastening member 51 is not completely separated from the cap 50, but separated to the extent that the fluid passage hole is exposed through the screw-fastening adjustment, so that the CN solution may be easily filled.
Further, a cap 60 is fitted around the spray port 41 to prevent the CN solution from being sprayed as the button member 40 is randomly pressed.
While the present disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
