Description

  The present invention mainly relates to a waste container, and more particularly to a technique that is effective when applied to a waste container having a bag-like container using resin or the like.

  Currently, waste generated in ordinary households or business establishments is separated by type, for example, incinerated, in order to effectively use resources through reuse and reduce the amount of waste processed. And incombustible materials that are not suitable for incineration and that are disposed of in landfills, etc., and are collected on the date determined by the type.

  In the collection, waste collected in plastic bags and sent to a designated collection point is collected by local collection vehicles. As the plastic bags used, plastic collection bags recommended by the local government called garbage bags are used, and other stores are distributed to store the products sold. In some cases, a resin bag called a plastic bag is used.

  For this reason, at home, it is necessary to transfer waste contained in a container such as a trash can to a collection bag. Therefore, in order to save the trouble of such transfer, it is considered to attach a collection bag to the container.

  For example, Patent Document 1 below describes a device for holding a garbage bag made of a synthetic resin film, and it has been proposed to directly put garbage into the garbage bag using this device.

JP-A-11-124202

  However, there is no problem if the dimensions match when the bag is held in the container. However, in such a case, an exception may be made. If the bag is small relative to the container, the weight of the stored garbage Problems such as the bag falling to the bottom of the container, the end of the bag falling over and not being able to keep the opening, etc., resulting in garbage collecting between the bag and the container and sanitary or aesthetic problems It may become.

  In order to avoid such problems, it is conceivable to stop the end of the bag with clothespins, etc., but since the resin is used for the bag or container, if a load is applied because the coefficient of friction is low It gradually falls.

  An object of the present invention is to solve these problems and provide a technique capable of firmly fixing an end portion of a bag to a container with a simple operation. The above and other problems and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings.

Of the inventions disclosed in this application, the outline of typical ones will be briefly described as follows.
An open end portion of the bag-like storage portion is fixed to a fixing portion having a locking portion attached to the frame body, and is a waste container that is supported by the support portion. The opening end of the bag-like storage part is fixed by a stopper fitted between the inner wall and the outer wall.

The effects obtained by the representative ones of the inventions disclosed in the present application will be briefly described as follows.
(1) According to the present invention, there is an effect that it is possible to securely fix the bag-like storage portion with a simple operation of pushing the opening end portion into the stopper.
(2) According to the present invention, even when the housing portion is removed, there is an effect that it is possible to release the locked state of the end portion of the housing portion with a simple operation of simply pushing down the stopper.

  Embodiments of the present invention will be described below. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

(Embodiment 1)
FIG. 1 is a front view showing a waste container according to an embodiment of the present invention.
The storage container of the present embodiment fixes the opening end of the bag-shaped storage unit 1 that stores waste to the fixed unit 5 in which the locking units 3 and 4 are attached to the frame body 2. 5 is supported by a support portion 6 having a rectangular tube shape. For the sake of explanation, FIG. 1 shows only the right half of the bag-like storage portion 1, and the exposed portion is hatched.

  The container 1 used in the present embodiment is a plastic shopping bag, and the opening end of the container 1 is connected to an annular end 1a for use as a handle during transportation, and prevents the contents from falling down. A strip-shaped end portion 1b is provided opposite to each other at two locations.

  Corresponding to such an open end, as the locking portions 3 and 4 of the fixed portion 5, the fixed locking portion 3 that hooks and locks the annular end 1a and the strip-shaped end 1b are locked. Movable locking portions 4 are provided opposite to each other at two locations.

  The frame 2 of the fixed portion 5 has a structure in which the inner wall 2a and the outer wall 2b are integrated at the upper side 2c, and the fixed locking portion 3 extends partially downward from the outer wall 2b. The annular end 1a is hooked.

  The support portion 6 is integrally molded with the inner wall 2a of the frame body 2 and has a cylindrical shape with a closed bottom surface. Therefore, waste is spilled to the outside due to the tearing of the container portion 1 having a thin film thickness. In addition, there is also a function of improving the aesthetic appearance by avoiding the exposure of the housing portion 1.

  FIGS. 2 to 7 are enlarged views of the movable locking portion 4. FIG. 2 is a front view of the unlocked state, FIG. 3 is a sectional view, and FIG. The front view of the state is shown in FIG. 4, the cross-sectional view is shown in FIG. 5, the front view of the locked state is shown in FIG. 6, and the cross-sectional view is shown in FIG.

  The movable locking portion 4 is attached to the gap between the inner wall 2a and the outer wall 2b, and contacts the slider 8 attached to the frame body 2 by the fixing pin 7 and the strip-like end portion 1b. A stopper 9 to be stopped is connected via a connecting portion 10. Further, in order to clearly show the slider 8 in the front view, the outer wall 2b is shown by appropriately cutting out the portion.

  The slider 8 is provided with an oval groove, and the shaft of the fixing pin 7 is fitted in this groove. The slider 8 rotates with respect to the axis of the fixing pin 7 and the axis of the fixing pin 7. Can be slid, and the direction and position can be changed along the inner wall 2a and the outer wall 2b.

  The shaft 8 a provided at the end of the slider 8 is fitted with a hole provided at one end of the connecting portion 10, and the hole provided at the other end of the connecting portion 10 extends from the end below the stopper 9. The shaft 9a provided on the side is fitted, the shaft 9a at the end of the stopper 9 and the shaft 8a at the end of the slider 8 are orthogonal, and the stopper 9 rotates about the shaft 9a at the end. The direction can be changed to take a form along the inner wall 2a and the outer wall 2b and a form perpendicular to the inner wall 2a and the outer wall 2b.

  2 and 3, the shaft of the fixing pin 7 is located at a position away from the stopper 9 in the groove of the slider 8, so that the slider 8 is in an extended state, and the stopper 9 has the inner wall 2a and the outer wall. The lower end of the inner wall 2a and the upper end of the stopper 9 are separated from each other in a state where it is removed from the gap between them.

  4 and 5, the stopper 9 is rotated with respect to the shaft 9 a so that the upper end of the stopper 9 opens forward, and the strip-like end 1 b of the shopping bag 1 is moved to the stopper 9. Between the inner wall 2a and the inner wall 2a.

  In this state, the accommodating portion 1 is placed inside the support portion 6, the accommodating portion 1 is opened along the inner wall 2 a, and the opening end of the accommodating portion 1 is folded on the outer surface of the outer wall 2 b of the frame body 2. After the strip-shaped end 1b is sandwiched between the stopper 9 and the inner wall 2a, the stopper 9 is returned to the position shown in FIGS. From this state, the stopper 9 is pushed up so that the strip-shaped end 1b shown in FIGS.

  In the locked state, the shaft of the fixing pin 7 is located near the stopper 9 in the groove of the slider 8, so that the slider 8 is in a contracted state. The interval between the fixing pins 7 is slightly narrower than the width required when no force is applied, based on the dimensions of the locking portion 4, that is, the width of the stopper 9 and the connecting portion 10 and the shape of the groove of the slider 8. .

  For this reason, by being restrained by the fixing pin 7, an elastic stress in the direction of reducing the width is generated in the locking portion 4 by the elasticity of the locking portion 4 in the locked state. As shown in FIG. 6, in this state, the slider 8 has the stopper 9 side facing upward, and therefore, an upward force is applied to the locking portion 4 by the elastic stress.

  FIG. 8 is a partially enlarged longitudinal sectional view showing the relationship between the fixed portion 5 in the locked state and the bag-shaped storage portion 1. In this figure, the film thickness of the accommodating portion 1 is exaggerated for the sake of explanation.

  The stopper 9 is tapered, and the shapes of the inner wall 2 a and the outer wall 2 b of the frame 2 are determined according to the shape of the stopper 9. For this reason, the stopper 9 is fitted in a wedge shape between the inner wall 2a and the outer wall 2b of the frame 2 and the upward force described above acts, so that the stopper 9 is caused by the elastic force acting in the left-right direction in FIG. The inner wall 2a and the outer wall 2b are pressed against each other.

  Therefore, the strip-shaped portion 1b sandwiched between the stopper 9 and the inner wall 2a or the outer wall 2b is pressed by the stopper 9 and the inner wall 2a or the outer wall 2b, and a force is applied to the strip-shaped portion 1b depending on the weight of the contents. Even if it is done, it does not shift. Further, by making the stopper 9 hollow, the elastic force acting in the left-right direction in FIG. 8 is increased.

  Further, the back surface of the stopper 9 is provided with a step 9b that is partially a protrusion, and this step 9b bites into the strip-like portion 1b, so that the frictional force of this portion is maximized. For this reason, when a force is applied to the strip-shaped end portion 1b due to the weight of the contents, and the strip-shaped end portion 1b and the portion in contact with the back surface of the stopper 9 are shifted from each other, an upward force is applied to this portion. Will join.

  This force gives an upward force to the back surface of the stopper 9, which has a stronger frictional force than the other portions. The upward force acting on the stopper 9 increases the pressure contact force between the stopper 9 and the frame 2, and the movement of the strip-shaped portion 1b is prevented by increasing the pressure contact force with respect to the increase in force. be able to.

  For this reason, it becomes possible to reliably fix the end portion of the accommodating portion 1 by a simple operation of pushing the strip-shaped end portion 1b with the stopper 9 therebetween. In addition, when removing the housing portion 1, it is possible to release the locked state of the end portion of the housing portion 1 with a simple operation of simply pushing down the stopper 9.

  The present embodiment is not limited to the above-described form, and can be applied to various forms as long as the opening end is fixed by the locking part 4. For example, FIG. 9 shows a modified example of the present embodiment. In this example, the container has a cylindrical shape, and considering the use of a garbage bag without the annular end portion 1a, a fixed type engagement is shown. Instead of the stop portion 3, movable locking portions are provided at four locations. Note that the number of the locking portions 4 can be increased or decreased depending on the state of the contents.

  Further, as the support portion 6, the frame body 2 of the fixing portion 5 is attached to a bowl-shaped body made of a metal material or a plant material such as wisteria, in addition to the resin molded integrally with the frame body 2. Can also be used.

(Embodiment 2)
Conventionally, waste separation has been divided into combustible materials to be incinerated and non-combustible materials that are not suitable for incineration and are subject to landfill disposal. May be further classified into metals, glass, resin, etc., and combustible materials may be further classified into paper, cloth, resin, etc., and collected. It tends to make it.

  When preparing a plurality of containers in accordance with such classification, the problem of location becomes an important solution. The present embodiment is particularly effective in such a case.

FIG. 10 is a front view showing a waste container that is another embodiment of the present invention.
The storage container of the present embodiment fixes the opening end of the bag-shaped storage unit 1 that stores waste to the fixed unit 5 in which the locking units 3 and 4 are attached to the frame body 2. 5 is supported by a support portion 6 having a rectangular tube shape. In FIG. 10, for the sake of explanation, the opening end of the bag-shaped storage unit 1 is shown only in the right half, and the exposed portion is hatched.

  In the present embodiment shown in FIG. 10, the housing portion 1 and the fixing portion 2 are substantially the same as those in the above-described embodiment, but the structure of the support portion is different, and the columnar support portion is a frame. It is attached to the corner of the body.

  The housing portion 1 used in the present embodiment is a plastic shopping bag, and the annular end portion 1a is hooked as the engaging portions 3 and 4 of the fixing portion 5 corresponding to the opening end portion. A fixed locking portion 3 to be locked and a movable locking portion 4 to lock the strip-shaped end portion 1b are provided opposite to each other at two locations.

  The movable locking portion 4 has the same configuration as that of the above-described embodiment, and the opening end portion of the housing portion 1 is folded on the outer surface of the outer wall 2b of the frame body 2 so that the strip of the housing portion 1 is folded. After the end 1b is sandwiched between the stopper 9 and the inner wall 2a, the stopper 9 is pushed up so that the strip-shaped end 1b is locked by the stopper 9.

  The stopper 9 is tapered, and the shapes of the inner wall 2 a and the outer wall 2 b of the frame 2 are determined according to the shape of the stopper 9. For this reason, the stopper 9 is fitted in a wedge shape between the inner wall 2a and the outer wall 2b of the frame 2, and the upward force described above acts, so that the stopper 9 is pressed against the inner wall 2a and the outer wall 2b by elastic force. Will be.

  Further, the back surface of the stopper 9 is provided with a step 9b. Since the step 9b bites into the strip-shaped end portion 1b, the frictional force at this portion is maximized. For this reason, when a force is applied to the strip-shaped end portion 1b due to the weight of the contents, and the strip-shaped end portion 1b and the portion in contact with the back surface of the stopper 9 are shifted from each other, an upward force is applied to this portion. Will join.

  This force gives an upward force to the back surface of the stopper 9, which has a stronger frictional force than the other portions. The upward force acting on the stopper 9 increases the pressure contact force between the stopper 9 and the frame 2, and the movement of the strip-shaped end portion 1b is prevented by increasing the pressure contact force with respect to the increase in force. can do.

  For this reason, it becomes possible to reliably fix the end portion of the accommodating portion 1 by a simple operation of pushing the strip-shaped end portion 1b with the stopper 9 therebetween. In addition, when removing the housing portion 1, it is possible to release the locked state of the end portion of the housing portion 1 with a simple operation of simply pushing down the stopper 9.

  The columnar support portion 6, which is a feature of the present embodiment, has a male screw at its upper end and is screwed with female screws formed at the four corners of the frame 2 of the fixing portion 5 so that its upper end is at the frame 2. The lower end is inserted into a hole provided in the tray 11 placed on the floor. In addition to fixing the lower end of the support portion 6, the tray 11 prevents the surroundings from being contaminated when moisture leaks out of the contents.

  As a method of attaching the upper end of the columnar support portion 6 to the fixing portion 5, an appropriate method such as bonding using a pin is conceivable. However, by adopting a method that is easy to attach and remove, the support portion 6 can be attached when not in use. There is convenience that does not take up space to store by removing. Conversely, the lower end of the support portion 6 may be fixed and the upper end inserted.

  Further, by forming the support portion 6 in a columnar shape, it is possible to easily adjust the length to an optimum state by providing a known length adjusting mechanism or cutting to an appropriate length. .

  Further, when the support portion 6 has a columnar shape as in the present embodiment, the front and side surfaces of the support portion 6 are opened. Therefore, as shown in FIG. There is an advantage that waste can be easily put into the container. For this reason, in consideration of the case where they are used in a stacked manner, a hole similar to the hole provided in the tray 11 is provided in the upper surface of the frame body 2, and the lower end of the upper support portion 6 is provided in the hole provided in the frame body 2. The lower end of the support part 6 is fixed by inserting.

  However, if they are simply stacked, if the height increases with respect to the bottom area, there will be a problem with stability, and further, the total load of the stacked containers will be concentrated on the bottom container, which will cause strength problems. Can be considered. For this reason, in the case of stacking, a practical limit is about three steps.

  Therefore, in the modification shown in FIG. 12, the above-described problems of stability and load are solved by attaching the fixing portion 5 to the two columnar support portions 6 attached to the wall surface or the like.

  A hole is provided at a corner near the back surface of the frame body 2. A columnar support portion 6 is passed through the hole, and a screw 12 screwed into the frame body 2 is tightened to fix the frame body 2 to the support portion. It is fixed to 6. The frame 2 can be moved along the support portion 6 and can be fixed at an appropriate height and the containers can be arranged at an optimal interval.

  As a method of attaching the frame body 2 to the support portion 6, other methods such as bonding using pins other than the screws 12 are conceivable. In addition, since the two support portions 6 are cantilevered, the height of the frame body 2 is increased as it approaches the attachment portion with the support portion 6 in consideration of the load distribution. It is desirable to ensure strength.

  Although the present invention has been specifically described based on the above-described embodiment, the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the scope of the invention. It is.

  For example, in the above-described embodiment, a resin bag is used as the housing portion 1. However, the present invention can be similarly applied to the case where other materials such as paper or cloth are used. In addition to storing waste, it can be used for other purposes such as storing laundry.
