In this regard, the disposable sheath 100 may be contained in the container 40 prior to use of the toilet plunger 10, may be taken out of the container 40 for use, and may be discarded after use, and a new disposable sheath 100 may be replenished in the container 40. A detailed structure of the disposable sheath 100 will be described below in detail.
The container 40 may be included in the plunger handle 20 shaped like an approximate rod and, for example, may be included in the plunger handle 20 in a tubular form so as to contain the disposable sheath 100 in a rolled state.
FIG. 3 is a diagram illustrating a disposable sheath 100 according to an exemplary embodiment of the present invention, FIG. 4 is a diagram illustrating a state in which the disposable sheath 100 illustrated in FIG. 3 is being affixed to a plunger prior to use of the toilet plunger 10, and FIG. 5 is a diagram illustrating a state in which the disposable sheath 100 is affixed to the toilet plunger 10.
Referring to FIGS. 3 to 5, the disposable sheath 100 according to an exemplary embodiment of the present invention may be affixed to the toilet plunger 10 so as to entirely cover the plunger cup 30 prior to use of the toilet plunger 10 and the toilet plunger 10 may be used while the disposable sheath 100 is affixed to the toilet plunger 10.
In particular, the disposable sheath 100 may be affixed to the toilet plunger 10 such that an effective plunging action of the toilet plunger 10 occurs even in a state in which the disposable sheath 100 is affixed to the toilet plunger 10.
That is, the disposable sheath 100 may be affixed to the toilet plunger 10 and may entirely cover the plunger cup 30 during use of the toilet plunger 10 so as to prevent the toilet plunger 10 from being contaminated and may be configured in such a way that an effective plunging action of the toilet plunger 10 occurs even in a state in which the disposable sheath 100 is affixed to the toilet plunger 10.
In detail, the disposable sheath 100 may include a cylindrical body 110, a bottom adhesive portion 120, a tab 130, and an edge adhesive portion 140.
The cylindrical body 110 may include a sealed bottom portion 112 and an open portion at an opposite side to the bottom portion 112.
The bottom adhesive portion 120 may be included in the bottom portion 112 of the cylindrical body 110, the tab 130 may extend from one side of an open portion 114 of the cylindrical body 110, and the edge adhesive portion 140 may be included in the tab 130.
The bottom adhesive portion 120 may be affixed to an internal surface of the plunger cup 30 and the edge adhesive portion 140 may be affixed to the plunger handle 20 during use of the toilet plunger 10.
In particular, the edge adhesive portion 130 may be affixed to the plunger handle 20 after the cylindrical body 110 is flipped to cover the plunger cup 30 while the bottom adhesive portion 120 is affixed to an internal surface of the plunger cup 30.
Thus, the toilet plunger 10 may not be contaminated in use because the plunger cup 30 and the plunger handle 20 are partially covered by the cylindrical body 110 of the disposable sheath 100 and the cylindrical body 110 of the disposable sheath 100 may be flipped while the bottom adhesive portion 120 is affixed to the internal surface of the plunger cup 30 so as to cover the plunger cup 30 and, thus, a sufficient space may be formed at the internal surface of the plunger cup 30 such that an effective plunging action occurs.
The edge adhesive portion 140 is affixed to the plunger handle 20 while the cylindrical body 110 of the disposable sheath 100 entirely covers the plunger cup 30, thereby preventing the cylindrical body 110 from slipping down or preventing water or contamination from being introduced into the cylindrical body 110 during use of the toilet plunger 10.
The sealed bottom portion 112 of the cylindrical body 110 may have a shape in proportion to a shape of an internal side of the plunger cup 30. For example, the sealed bottom portion 112 of the cylindrical body 110 may be shaped like an approximate hemisphere that is a general shape of the plunger cup 30.
Then, when the bottom adhesive portion 120 is affixed to the internal surface of the plunger cup 30, a sufficient space is secured at an internal side of the plunger cup 30 and, thus, an effective plunging action may occur during use of the toilet plunger 10.
Similarly, the bottom adhesive portion 120 that is approximately circular-shaped may be included in the bottom portion 112 such that an effective plunging action occurs.
The cylindrical body 110 may be formed in such a way that the open portion 114 is wider than the bottom portion 112. Then, the cylindrical body 110 may be easily flipped to cover the plunger cup 30 while the bottom adhesive portion 120 is affixed to the internal surface of the plunger cup 30.
The cylindrical body 110 may be formed of an impermeable material so as to prevent the toilet plunger 10 from being contaminated during use of the toilet plunger 10 and, in particular, may be formed of resilient low-density polyethylene (LDPE) so as to prevent the sealed bottom portion 112 from being torn during the plunging action.
FIG. 6 is a diagram illustrating a state in which the disposable sheath 100 is separated after use of the toilet plunger 10. FIG. 7 is a diagram illustrating a state in which the disposable sheath 100 separated from the toilet plunger 10 is rolled.
As illustrated in FIG. 6, the disposable sheath 100 may be configured in such a way that, when the edge adhesive portion 140 is separated from the plunger handle 20 and then the cylindrical body 110 is flipped after use of the toilet plunger 10, contaminants on the cylindrical body 110 during use of the toilet plunger 10 are collected inside the cylindrical body 110.
As such, when contaminants are collected inside the cylindrical body 110 and then the bottom adhesive portion 120 is separated from the internal surface of the plunger cup 30, contaminants accumulated during use of the toilet plunger 10 may be separated from the toilet plunger 10 while being collected inside the cylindrical body 110.
Accordingly, when the disposable sheath 100 according to the present invention is used, it may be convenient that it is not necessary to separately wash the toilet plunger 10 after use.
The bottom adhesive portion 120 and the edge adhesive portion 140 may have weak adhesion so as to be easily affixed and separated and a strip may be coupled to each of the bottom adhesive portion 120 and the edge adhesive portion 140 so as to prevent foreign substances from being adhered thereto.
As illustrated in FIG. 7, the disposable sheath 100 that is separated after use of the toilet plunger 10 may be fixed using the edge adhesive portion 140 while being rolled and, thus, may be discarded in a compact state.
