Title: Wastebasket with enhanced load-bearing capacity

Description:
TECHNICAL FIELD 
     The present invention relates to a wastebasket, and more specifically to a wastebasket in which a plastic bag is contained. 
     BACKGROUND ART 
     Waste is always generated. Accordingly, wherever people live, there are wastebaskets. People cover wastebaskets with plastic bags, and throw waste into the plastic bags. Thereafter, they separate the plastic bags from the wastebaskets, and discard the plastic bags together with the waste. Without such plastic bags, wastebaskets become dirty due to waste, which is bad in terms of sanitation. Furthermore, people feel inconvenient when they throw waste into wastebaskets. Due to these points, people want plastic bags sufficient to use, and vinyl pack products meeting this need are supplied to the market. 
     Meanwhile, there are frequent cases where a plastic bag for a wastebasket is not available. In these cases, embarrassment is probably experienced by many people. Accordingly, there occurs the idea in which if a plastic bag is contained in a wastebasket, this would be much more comfortable. For example, Korean Utility Model Registration No. 443070 (Patent document 1) and Korean Utility Model Registration No. 468598 are based on such ideas. 
     The prior arts propose the solutions in which if the plastic bag roll packs of FIG. 5 (not a drawing of the present specification) of Patent document 1 and FIG. 3 (not a drawing of the present specification) of Patent document 2 are contained and used in wastebaskets, users do not need to make an effort to find plastic bags. 
     However, as the size of a wastebasket is increased, a problem that has not been foreseen in the prior arts has been found. As the volume of a wastebasket is increased, the volume of a plastic bag used in the wastebasket increases naturally. Then, the load of waste that the plastic bag has to bear will also increase. Load-bearing capacity becomes a problem. The plastic bags of the prior arts are easily torn as a load increases. In particular, when the amount of waste increases because heavy waste such as a bottle or a can is introduced into such a plastic bag, the bottom thereof is broken. The bottom sealing line thereof is very fragile. 
     It is difficult to require a user to take special measures to solve this problem. For example, it may be contemplated that a user is asked to use two plastic bags at the same time or not to put heavy waste into the wastebasket. However, the user&#39;s interest is to use a waste bag as easily as possible, not to use it carefully. Increasing the strength of the material of the waste bag may be one way. However, in this case, the price goes up. The waste bag is also waste. There is no user who is willing to pay more for waste. 
     Meanwhile, a user does not want to touch a bag containing waste with his or her hand if possible. Accordingly, a user does not want to perform the operation of opening the entrance of a waste bag every time he or she puts waste in the bag. If so, it is necessary to keep the waste bag open. However, when waste is contained in the waste bag, the entrance of the waste bag is pulled downward due to the load of the waste. Then, a problem arises in that the user needs to open the entrance while holding the entrance with his or her hands when introducing waste into the waste bag. That is, there is a need for the entrance to be effectively kept open on the top of a wastebasket despite the load of waste. 
     In order to solve these problems, the inventor of the present invention has realized that a radically different approach needs to be made beyond the conventional concepts of a plastic bag and a wastebasket after repeated trial and error, and has come to complete the present invention. 
     DISCLOSURE 
     Technical Problem 
     An object of the present invention is to propose a new concept-based plastic bag cartridge that that is contained and used in a wastebasket. Furthermore, another object of the present invention is to propose an unprecedented, novel wastebasket in which a plastic bag cartridge is contained. 
     More specifically, an object of the present invention is to propose the following plastic bag: 
     First, the present invention is intended to implement a plastic bag that has enhanced load-bearing capacity, even though the volume thereof is increased. The fabrication of a plastic bag that is 500 to 1,000 mm in length and 200 to 500 mm in diameter when folded is taken into account. 
     Second, manufacturing cost has to be inexpensive. Since there is concern that the selection and changing of the composition of the material of a plastic bag may lead to an increase in manufacturing cost, the present invention proposes a method of enhancing load-bearing capacity only by structural improvement. 
     Third, an object of the present invention is to propose the new structure of a wastebasket that may be stably kept open despite the load of waste when a plastic bag is taken from a cartridge and is installed in the wastebasket. 
     This further promotes the popularization of the wastebasket in which a plastic bag is contained.

     MODE FOR INVENTION 
     In the following description of the present invention, when it is determined that detailed descriptions of related well-known functions are apparent to those skilled in the art and may make the gist of the present invention unnecessarily obscure, they will be omitted. 
       FIGS. 1 and 2  show the schematic external configuration of a wastebasket  100  according to any preferred embodiment of the present invention.  FIG. 1  shows the wastebasket  100  in a closed state, and  FIG. 2  shows the wastebasket  100  in an open state. 
     The wastebasket  100  made of a plastic or metal material includes a body  110  and a lid  120 . The lid  120  includes hinge members  125  and  126  and a grip  121 , and selectively opens and closes the entrance of the body  110 . 
     When the wastebasket lid  120  is opened, a wastebasket top entrance E is opened, as shown in  FIGS. 2 and 3 . An upright surface  135  surrounding the top entrance E is formed by a protruding surface  130  that is perpendicular to the upright surface  135 , extends in a circumferential direction, and is formed like a flange. An adhesive film  140  is disposed along a surface of the upright surface  135 . AS will be described later, this adhesive film  140  is used as a means for enhancing force that holds the entrance of a plastic bag contained in the wastebasket  100 . 
     A protruding grip portion  131  is formed in the same plane as the protruding surface  130 , and a lid locking portion  132  is disposed on the protruding grip portion  131 . The catch of the lid  120  is fitted into the lid locking portion  132  in a fitting manner. There is disposed a well-known latch  133  that is operated by a method in which fitting is released by pressing the grip once more. 
       FIG. 4  visually shows an example of the lower configuration of the wastebasket  100  according to the present invention. A bottom housing  190  is disposed in a bottom surface in the wastebasket, and a cartridge accommodation portion  195  having a shape depressed to a predetermined length from the bottom surface is formed in the bottom housing  190 . A plastic bag cartridge to be described later is accommodated through the cartridge accommodation portion  195 . 
     The wastebasket may be formed in a hexahedral shape or a cylindrical shape. There are no limitations to the specifications, shape and size thereof. As shown in the drawings, in the case of a hexahedral wastebasket, it is preferable that supports  189  be disposed in the lower portions of the corners of the inside of the wastebasket  100 . 
       FIGS. 5A and 5B  show only the bottom configuration of the wastebasket  100  separately. As shown in  FIG. 5A , the cartridge accommodation portion  195  is a space the cross section of which is an approximately depressed semicircular shape. As shown in  FIG. 5B  taken along line X-X of  FIG. 5A , the cartridge accommodation portion  195  is an empty space before the plastic bag cartridge is mounted therein. It is preferable that the hatched portion of the bottom housing  190  be also an empty space. In other words, the configuration of the bottom housing  190  is defined by boundary surfaces. 
     The cartridge accommodation portion  195  is mounted with a plastic bag cartridge according to the present invention. The plastic bag cartridge will now be described. The plastic bag cartridge of the present invention may be packaged and sold as an independent product by itself. Furthermore, it may be preferably mounted and used on the wastebasket. 
       FIG. 6  schematically illustrates the roll pack configuration of a plastic bag cartridge according to any preferred embodiment of the present invention. 
     The plastic bag cartridge has a form in which successive and connected unit plastic bags  10  to be described later are wound around a paper cylinder  40  with an open top and bottom. Furthermore, a first unit plastic bag  10  is fastened to a roll pack  30  with a sticker  50 . 
     As described above, the plastic bag roll pack  30  according to the preferred embodiment of the present invention may have the same form as a toilet paper roll. In another preferred embodiment of the present invention, the plastic bag cartridge has a structure in which unit plastic bags  10  are successively folded and stacked and pulled out one by one for the purpose of use like Kleenex™ tissues. The plastic bag cartridges of these two embodiments each include the successive plastic bags of the unit plastic bags  10 . In these plastic bag cartridges, the configurations of the unit plastic bags  10  are substantially the same. Accordingly, the configuration of one unit plastic bag  10  will be described. 
       FIG. 7  schematically shows the planar configuration of a unit plastic bag  10  according to any preferred embodiment of the present invention. 
     The unit plastic bag  10  is substantially the same as the conventional plastic bag in that it has an approximately rectangular structure, both ends thereof, i.e., the entrance and cut end thereof, in the longitudinal direction have the same configuration, and there is a sealing line sealed parallel to these ends. However, the unique configuration of the present invention in which, as will be described below, folded portions are formed on both sides in the longitudinal direction and sealing lines and cutting lines are sequentially formed on a continuous plastic member in a double/triple folded and stacked state is a technology that was not thought of in the conventional technology. 
     As a waste bag for separate collection purposes, the length of the unit plastic bag is preferably 500 to 1000 mm. The inventor of the present invention took a length of 700 mm, and fabricated the unit plastic bag. The width of the entrance of the unit plastic bag was 450 mm when the unit plastic bag was unfolded. However,  FIG. 7  shows a state in which the unit plastic bag is folded a few times in the widthwise direction, and the width in this state was about 110 to 120 mm. The width may be smaller or larger. 
     The entrance line  11  of the unit plastic bag  10  is open, and the opposite side is sealed by the sealing line  18 . Meanwhile, the unit plastic bag  10  is folded a few times in the widthwise direction, and thus the entrance line  11  has an approximately zigzag form (exactly, it will be described again with reference to  FIGS. 8 to 10 ). In contrast, although the sealing line  18  will be descried with reference to  FIG. 11 , a plurality of support partitions is disposed by the sealing line  18 . 
     The end line  19  of the unit plastic bag  10  constitutes one side of a cutting line not shown. The other side of the cutting line constitutes the entrance line  11  of another connected unit plastic bag  10 . In other words, the end line  19  of the first unit plastic bag is the entrance line  11  of a second unit plastic bag connected to the first unit plastic bag. These unit plastic bags are connected through the cutting line until they are separated by cutting. The configurations of all the unit plastic bags  10  of the plastic bag cartridge configured in a connected plastic bag form are the same. Furthermore, if we understand the configuration of the entrance line  11 , the overall configuration of the plastic bag cartridge may be intuitively or analytically understood. 
     See  FIGS. 8 and 9 .  FIG. 8  shows the enlarged configuration of the entrance line  11  of the unit plastic bag  10  and its surroundings. Folded portions M 1  and M 2  are formed on both sides of the unit plastic bag  10  in the longitudinal direction. The pair of folded portions M 1  and M 2  form an approximate M shape in a plan view when viewed from above after the entrance has been slightly opened. The shapes of the pair of folded portions M 1  and M 2  are symmetrical to each other. Accordingly, when the folded portion M 2  on the right has an M shape, the folded portion M 1  on the left forms an inverted M shape. In this case, the M shape does not mean an exact coincidence with the letter M, but is borrowed to express a configuration in which a plastic bag sheet is folded on both sides along the longitudinal direction. In fact, as will be described later, the portions of a member are in close contact with each other because the plastic bag does not have shape retention force and is packed in a folded and stacked state. It is added that the M shape is observed only when the entrance is slightly opened with hands. 
     Since the specifications of the connected plastic bags are all the same, the configuration shown in  FIG. 8  applies equally to all the plastic bags connected in the longitudinal direction. 
     In the drawing, eight feature points are marked on the entrance line for convenience of description. In the entrance line  11  of the folded part M 1  on the left side, the line extends in the sequence of 5, 9, 8, 7 and 5. In the entrance line  11  of the folded part M 2  on the right side, the line extends in the sequence of 5, 1, 2, 3 and 5. The size of the distance between the feature points 2 and 8 affects the M shape and also the volume of the waste bag. When a larger volume is desired, the distance between the feature points 2 and 8 is preferably 0 to 10 mm. Even when the distance is zero, there is no problem with being folded due to material properties without shape retention force. 
     Meanwhile, 5 is given to two of the above feature points. The reason for this is as follows: 
     From the state of  FIG. 8 , the member is folded around 180° along a center portion (indicated by the dotted line) in the longitudinal direction so that the right portion  10   b  of the member is superimposed on the left portion  10   a  of the member. This allows for the two feature points 5 to become a single feature point 5. 
       FIG. 10  more naturally shows the entrance line  11  in an enlarged view. The fully folded entrance line  11  of the unit plastic bag  10  is opened by slightly holding and pulling the feature point 3. The entrance line part extending in the sequence of feature points 5 (not shown), 9, 8, 7 and 5 corresponds to the left portion  10   a  of the member of  FIG. 8 . Furthermore, the entrance line part extending in the sequence of feature points 5, 3, 2, 1 and 5 (not shown) corresponds to the right portion  10   b  of the member shown in  FIG. 8 . 
     It is assumed that the unit plastic bag  10  of the present invention is separated from the roll pack  30 , which is a plastic bag cartridge, and is then used. This allows the unit plastic bag  10  to be separated from the roll pack  30  along the cutting line ( 19  in  FIG. 7 ). One side of the unit plastic bag  10  is closed by the sealing line  18 , and the other side is opened by the entrance line  11 . By doing so, a waste bag is formed. The entrance line  11  has already been described. The internal configuration of the sealing line  18  is important. The reason for this is that the load of waste introduced into the plastic bag does not cause a problem with the entrance side but causes a problem with the lower configuration of the plastic bag where the sealing line  18  is present. 
     A description will now be given again. The M-shaped folded portions M 1  and M 2  are formed on both sides of the member of the unit plastic bag  10 . When viewed from the point of view of  FIGS. 8 to 10 , inward folding is performed such that the line of feature points 8 in the longitudinal direction and the line of feature points 2 in the longitudinal direction are formed. This results in two folded portions. From this state, folding is performed around 180° along the center portion, as shown in  FIG. 9 . This results in 2×2, 4 folded portions. This folded state is applied to the overall plastic bag member. Thereafter, sealing lines and cutting lines are allocated at predetermined intervals. The entrance structure formed by the cutting line has been fully described in  FIGS. 8 to 10 . The internal structure formed by the sealing line will now be described below. 
       FIG. 11  provides the description. Since the sealing line is formed across the member in the state where there are four folded portions, four support partitions  14 ,  15 ,  16  and  17  are formed on the bottom of the unit plastic bag  10 . Furthermore, four valleys o, p, q and r are formed between the four support partitions  14 ,  15 ,  16  and  17 . The height of these support partitions refers to the length of the sealing line. Furthermore, this corresponds to the width of the unit plastic bag  10  in a state in which the unit plastic bag  10  is wound around the roll pack, i.e., a folded state. This may be about 110 to 120 mm. 
     There is formed a structure in which the support partitions  14 ,  15 ,  16  and  17  rise like mountains in the center portion of the bottom of the plastic bag  10 . The sealing line rises in the vertical direction in four directions, which improves the resistance to the load of waste to be introduced. 
     As a result, in the present invention, the sealing line forms four load-bearing members. Furthermore, the support partitions  14 ,  15 ,  16  and  17  formed in the center portion of the bottom of the plastic bag provide shape retention force to the center portion of the bottom of the plastic bag. This is helpful in throwing away a small amount of light waste. 
       FIGS. 12 and 13  illustrate a state in which the unit plastic bag  10  is used with reference to the embodiment of the present invention shown in  FIGS. 1 and 2 . 
     In  FIG. 12 , a cartridge accommodation portion is disposed in the lower portion of the inside of the body of a wastebasket  100 . The above-described successive plastic bags are installed in the cartridge accommodation portion as a plastic bag cartridge, e.g., in a roll pack form. After the roll pack has been installed in the cartridge accommodation portion, a first unit plastic bag  10  is taken from the roll pack, an end portion of the entrance of the unit plastic bag  10  is bent along the upright surface  135  of the top entrance of the wastebasket  100  in “a state of being connected to a subsequent unit plastic bag,” and then the end portion of the entrance of the unit plastic bag  10  is brought into close contact with the upright surface  135  of the top entrance of the wastebasket  100 , as shown in portion “A.” By doing so, the adhesive film  140  formed on the upright surface  135  and the surface of the end of the entrance of the unit plastic bag  10  come into close contact with each other along the circumference of the top entrance of the wastebasket, and are then attached to each other naturally. Since overall attachment is performed throughout 360°, the unit plastic bag  10  is securely fastened to the upper portion of the wastebasket in a state in which the entrance of the unit plastic bag  10  is opened. In the state, the wastebasket lid  120  is closed, as shown in  FIG. 13 . 
       FIGS. 14 to 16  show a wastebasket according to another preferred embodiment of the present invention. In the present embodiment, a vinyl sheet cartridge  200  containing folded and stacked lid protecting vinyl sheets  210  configured to prevent the inner surface of a lid  120  from being contaminated with waste is attached particularly to any surface of the outside of a body  110 . 
     As shown in  FIG. 14 , a plurality of vinyl sheet adhesion films  128  is separately disposed at the corners of the inner surface  129  of the wastebasket lid  120 . Furthermore, an approximately rectangular lid protecting vinyl sheet  210  is adhered to the inner surface  129  of the wastebasket lid via the vinyl sheet adhesion films  128 . This lid protecting vinyl sheet  210  prevents introduced waste from coming into direct contact with the inner surface  129  of the wastebasket lid when the waste is introduced into the wastebasket  100 , thereby enhancing the sanitation of the wastebasket lid. 
     As shown in  FIG. 15 , the lid protecting vinyl sheet  210  comes into close contact with and is then adhered to the vinyl sheet adhesion films  128  disposed on the four corner portions of the lid inner surface  129 . The locations at which the vinyl sheet adhesion film  128  are disposed and the number thereof are selected as desired. The adhesive films  128  are adhesion means well known as means for selectively attaching and detaching a member. However, it is added that the configuration “lid protecting vinyl sheet  210 ” is novel and the effect in which the adhesion means are disposed on the inner surface  129  of the wastebasket lid  120  and the sanitation of the lid is provided using a unprecedented method is novel. 
     Meanwhile, in the present invention, there may be prevented the burden in which a user has to find a new component means called the lid protecting vinyl sheet  210  somewhere in a hard way. In other words, the vinyl sheet cartridge  200  is attached to any one surface of the outside of the wastebasket body  110 . 
       FIG. 16  shows an example of the configuration of the vinyl sheet cartridge  200  according to the present invention. As shown in the drawing, a number of lid protecting vinyl sheets  210  are folded and contained in the vinyl sheet cartridge  200 , and an entrance  201  formed as a cutout is formed in the surface of one side of the vinyl sheet cartridge  200 . A user may take one lid protecting vinyl sheet  210  out through the entrance  201 , and may then adhere and use the lid protecting vinyl sheet  210  onto the wastebasket lid inner surface  129 , as shown in  FIGS. 14 and 15 . An existing adhered lid protecting vinyl sheet  210  is separated from the lid inner surface  129  and discarded into the wastebasket  100 , and a new vinyl sheet  210  is taken out via the vinyl sheet cartridge  200  and newly adhered onto the lid inner surface  129 . 
     The vinyl sheet cartridge  200  of  FIG. 16  is attached to any one surface of the wastebasket body  110  by a means such as an adhesive or sticking agent. The vinyl sheet is composed of an approximately rectangular sheet as described above. It is sufficient if the size of the vinyl sheet protects the lid inner surface  129 . Accordingly, the size of the vinyl sheet will be previously determined by considering the size of the wastebasket, and then the vinyl sheet will be fabricated. The size and material of the vinyl sheet cartridge  200  in which such vinyl sheets are sequentially folded and contained are selected as desired. The vinyl sheet cartridge  200  preferably have specifications in which the shape thereof is an approximately rectangular shape and the length of each side thereof ranges from 150 to 200 mm. 
       FIG. 17  shows the configuration of a wastebasket  100  according to still another embodiment of the present invention. As shown in the drawing, four plastic bag cartridges are contained, and unit plastic bags  331 ,  332 ,  333  and  334 , which may individually accommodate waste according to the principle of  FIG. 12 , are installed. 
     However, in the present embodiment, protruding portions  230  are disposed alongside each other on both sides in the longitudinal direction in order to enhance the support force used when a plastic bag accommodates waste, and thus the entrance lines of the unit plastic bags  331 ,  332 ,  333  and  334  are hung on the protruding portion  230 . More preferably, an adhesive film such as the adhesive film  140  of the embodiment of  FIG. 2  is preferably attached to the surfaces of the protruding portions  230 . Reference symbol  320  designates a grip, and reference symbol  330  designates a wastebasket hook eye. 
     The present embodiment has an advantage in that a single wastebasket body and a single wastebasket lid are included. 
     Meanwhile, the scope of the present invention is not limited to the specific composition and fabrication process of plastic bags. Furthermore, the scope of the present invention is not limited to the descriptions and expressions of the embodiments explicitly described above. Finally, it is also added that the scope of the present invention may not be limited by an alteration or substitution that is obvious to in the art to which the present invention pertains.
