Description

COMPRESSIBLE WASTE BASKET < RTI ID = 0.0 >

One embodiment of the present invention relates to a compression type trash can which can reduce the volume by compressing the waste paper received in the trash can.

Generally, a trash can for storing or collecting garbage is placed in a home, an office, or an industrial site. In order to avoid the inconvenience that users often have to empty the trash frequently, the trash in the trash can be squeezed from time to time to reduce the volume .

In addition, recently, since the garbage bag is used only by using the standardized garbage bag due to the implementation of the garbage baggage system, the necessity of such garbage compaction is more urgent to save the purchase cost of the standardized garbage bag.

However, since there is no separate structure for trash compression in the conventional trash bin, in order to compress the trash in the trash can, the user has to push the trash downward by pushing the hand or foot directly into the trash can, And there was a lot of difficulty in the garbage compaction work such as garbage being easily buried in the user's body during the garbage compaction work.

FIG. 2 is a top view showing the upper cover of FIG. 1, FIG. 2B is a top view showing the guide cover of FIG. 1, and FIG. 2C is an exploded perspective view of the compression garbage can according to an embodiment of the present invention. Is a front view showing the conical coil spring of Fig. 1, and Fig. 2 (d) is a front view showing the support container of Fig.

1, a compression type waste bin 1 according to an embodiment of the present invention includes a compression member 10, a cover member 20, a support container 30, and a plastic bag V. As shown in Fig.

The compression member (10) is arranged to extend and retract in the vertical direction to form a basic frame of the trash can (1). The compression member 10 includes a stretchable and contractible portion 110 that is stretchable and contractible by a pressure acting on the upper portion of the compression member 10 and a support portion 120 that supports the lower portion of the stretchable and contractible portion 110, ).

The inner diameter of the stretchable and contractible portion 110 is larger than the inner diameter of the support portion 120. That is, the compression member 10 is formed such that its inner diameter gradually changes from the expandable portion 110 to the support portion 120. At this time, the stretching force of the stretchable and contractible portion 110 is formed larger than the stretching force of the support 120.

The stretchable and contractible portion 110 and the support portion 120 are integrally injection-molded. More preferably, the stretchable and contractible portion 110 and the support portion 120 are integrally formed through insert injection. In the present invention, the extensible and contractible part 110 and the support part 120 are integrally formed by injection molding, thereby eliminating the need for a separate assembly step, thereby improving the manufacturing process and production efficiency.

Referring to FIG. 2C, the compression member 10 may be formed of an elastic member that can be stretched up and down. Preferably, the compression member 10 may be a conical coil spring. The conical coil spring has a conical shape in which the coil inner diameters D1 and D2 are gradually changed in the vertical direction and is elongatable and contractible along the vertical direction and has an elastic force so that the compression member 10 can maintain the unfolded state . The conical coil spring is formed such that the coil spacing of the expandable portion 110 is relatively close to the coil spacing of the support portion 120. In addition, the conical coil spring is formed such that the inner wall of the conical coil spring is tilted outward when compressed by the user, so that the pressure from the upper portion is uniformly transmitted to the lower portion. Further, since the portion corresponding to the support 120 is inserted into the guide protrusion 302 formed on the outer surface 301 of the support container 30 and fixed firmly, the conical coil spring does not require a separate fixing structure, The process can be simplified.

The compression member 10 may be a leaf spring (refer to 401, 402 in Fig. 3) designed to have a vertically expandable structure. An explanation of an example in which the compression member 10 is constituted by a leaf spring will be described in the following description with reference to Fig.

Meanwhile, the perimeter of the compression member 10, that is, the peripheries of the conical coil spring or the leaf spring, may be coated with a fragrance material having a sterilizing and disinfecting function, thereby sterilizing the periphery of the conical coil spring or leaf spring, It is possible to maintain a clean state by processing. The functional oil may be mixed with 95 to 97% by weight of the perfume, 3 to 5% by weight of the functional oil may be mixed with the perfume oil, 50% by weight of the curry plant, And 50% by weight of Santolina. It is preferable that the functional oil is mixed in an amount of 3 to 5% by weight with respect to the perfume. If the mixing ratio of the functional oil is less than 3 wt%, the effect is insignificant. If the mixing ratio of the functional oil exceeds 5 wt%, the function is not greatly improved, but the manufacturing cost is greatly increased. The curry plant has nerol, neryl acetate and geraniol as main chemical components, and exhibits excellent effects such as anticonvulsant, antibacterial, antiviral, antibacterial and bacterial toxic effects. The main chemical components of the Santolina include borneol, cineole, camphene, and are excellent in insecticidal, antibacterial, and bactericidal effects. Accordingly, in the present invention, a functional oil is coated around the conical coil spring or the leaf spring to sterilize and disinfect the circumference of the conical coil spring or the leaf spring to maintain a clean state and prevent contamination, . ≪ / RTI >

The support portion 120 is divided into a region having a height of 1/5 to 2/5 of the total height (i.e., the total height of the trash can) (H1 + H2) of the upper portion of the booty to the lower side of the compression member 10 . When the supporting portion 120 has a height H2 smaller than 1/5 of the total height H1 + H2 of the trash can 1, the supporting force of the stretchable and contractible portion 110 weakens, And the supporting part 120 has a height H2 greater than 2/5 of the total height H1 + H2 of the trash can 1, the upper part of the trash can 1 may be exposed The area where the elastic force of the stretchable and contractible portion 120 due to the pressurizing action is applied becomes small.

When the compression member 10 is formed of a conical coil spring, the trash bin 1 according to the present invention inserts the plastic bag V into the conical coil spring, and then moves the upper area of the plastic bag V to the trash can 1, The upper cover 21 is made to pass through the outer cover 21 and is fixed to the guide cover 22 and used.

That is, if the user desires to have a lot of tissue while discarding the tissue paper having a relatively large volume such as a tissue or the like and does not cause bad odors, the user presses or presses the top cover 21 using his or her hands or hands, When the user releases his / her foot or hand from the upper cover 21, the conical coil spring moves the upper cover 21 ) Moves upward and returns to its original position.

The cover member 20 is a member provided to cover the open top of the compression member 10 and includes a guide cover 22 and an upper cover 21. [

Referring to FIG. 2B, the guide cover 22 is formed to have a shape corresponding to the shape of the upper portion of the compression member 10, the center portion of which opens. That is, when the compression member 10 is a conical coil spring, the guide cover 22 may have a circular shape corresponding to the circular shape of the upper portion of the compression member 10. The inner diameter of the guide cover 22 is formed to be equal to or larger than the outer diameter of the upper portion of the compression member 10 to cover the upper portion of the compression member 10. The guide cover 22 includes a rim portion 221 that is fitted and fixed to the upper portion of the compression member 10 and a seating portion 222 to which the upper cover 21 is coupled inside the rim portion 221.

2A, the upper cover 21 is covered with the seating portion 222 of the guide cover 22, and the upper cover 21 is rotated in a state where the hinge is coupled to the surface of the seating portion 222 while being vertically opened and closed . The upper cover 21 is formed to be convex downward and includes an opening and closing plate 211 covering the opened area of the upper cover 21 and a handle 212 formed on the area formed convexly on the opening and closing plate 211 .

Referring to FIG. 2D, the support vessel 30 has a cylindrical shape having a predetermined depth and is formed to have an open top. The inner surface of the support container 30 is opened to receive the plastic bag V and the outer surface 301 is formed with an embossed guide protrusion 302 such that the inner surface of the compression member 10 is fixed. The guide protrusions 302 may be formed in plural numbers so as to surround the outer side surfaces in the vertical direction. For example, when the compression member 10 is a conical coil spring, the guide protrusion 302 is installed along the valley between the guide protrusions 302. However, the present invention is not limited to this, and may be formed in various shapes corresponding to the shape of the stretchable and contractible portion 110 of the compression member 10 .

The plastic bag V is fitted into the inside of the compression member 10, and the upper region thereof is passed through the cover member 20 to be exposed in the outward direction. The vinyl bag V which is turned out in the outward direction and goes out is fixed by covering the upper cover 21. [

That is, when the user presses the upper cover 21 downward, the compressible trash can according to the present embodiment reduces the width between the conical coil springs, and the conical coil spring is compressed, When the force applied to the upper cover 21 by the user is removed in this state, the space between the coils is restored to the original state by the elastic restoring force of the conical coil spring, and the conical coil spring is maintained in the unfolded state . In this way, the waste in the conical coil spring is collected in a compressed state in the lower side of the plastic bag (V), so that the inside of the plastic bag (V) The inner upper space can again be filled with more tissue.

As described above, since the compression type waste bin 1 according to the present embodiment is provided so that the conical coil spring can be stretched and contracted along the longitudinal direction, it is possible to prevent the user from directly pressing the garbage with his / The upper cover 21 is pushed downward by the upper cover 21 so that the toilet paper contained in the plastic bag V in the conical coil spring is pressed against the upper cover 21 to be easily compressed.

Accordingly, the present compression type trash can 1 not only facilitates the compression action of the rest, but also effectively prevents the foreign body from being buried in the user's body during compression of the rest.

In addition, since the conical coil spring in a state of being compressed through the conical coil spring can naturally be unfolded through the conical coil spring, the compressible trash can 1 is provided with a separate force for restoring the crushed trash can 1 So that it is not necessary to apply it.

3 is an exploded perspective view showing a compression type waste bin 2 according to another embodiment of the present invention. FIG. 3 is a view showing the structure of the compression type recycle bin shown in FIG. 1 to FIG. 2D and the structure of the compression member 40 and the support container 60, wherein the structure shown in FIG. 1 to FIG. The description of the different compression members 40 and the support vessel 60 will be mainly discussed.

The compression member 40 is configured such that a plurality of wave-shaped leaf springs 401, 402 are arranged to extend and retract in the vertical direction. At this time, at least one stretchable space S is formed between adjacent leaf springs 401, 402 among the plurality of leaf springs 401, 402. The expansion and contraction space S is formed such that a block or concave portion of the leaf spring 401 located on the upper side and a concave or convex portion of the leaf spring 402 located on the lower side face each other. At this time, the joining between the adjacent leaf springs 401 and 402 can be performed through a welding process or a joining process through a separate joining means (not shown) to the joining portion 403 located in a region where the joining portions 403 are in contact with each other. Therefore, in the present embodiment, the compression member 40 can be expanded and contracted in the vertical direction through the expansion and contraction space S formed between the adjacent leaf springs 401, 402, thereby realizing the compression type trash can 2.

The supporting protrusion 602 of the embossing shape is formed on the outer side surface 601 in order to support the structure and operation of the leaf springs 401, .
