Description

Compressible garbage bag holder

The present invention is being discussed in relation to a compressible garbage bag holding device.

In order to reduce the cost of garbage disposal (charged by the volume of garbage), for example, one of the garbage containers that can be used for garbage should be optimally used. However, the trash is usually only loosely placed in a garbage container without saving a lot of space, and a large empty volume is still unused. To attempt to make better use of the volume, the trash is typically at least partially compressed in the trash container using a hand, foot or a separate pressing plunger. However, once the pressure application is over, the once compressed waste is again partially expanded in the waste container.

On the one hand, a garbage bag mainly made of plastic is used as the sole garbage containing container, and is used in combination with a rigid container in which the garbage bag is clamped. Garbage bags are easy to transport and handle. When a garbage bag disposed in a garbage container and loosely connected to the garbage container is used, the garbage bag and the garbage container generally do not correspond in shape and volume, so that the available garbage bag volume cannot be completely used. Under tensile stress, such as when the contents of a trash bag are compressed, the trash bag is further at risk of sudden opening or tearing.

It is known from DE 40 23 843 A1 to include a trash can with an integrated compression function. The trash can consists of a bottom, a casing surface and a closure cover that is attached to the bottom and separated in a tubular manner. The housing surface includes individual portions that are axially displaceable into each other. These departments The points are displaced along the guide rods (the guide rods are arranged outside the housing surface and on which pressure elements embodied as spring elements are arranged) to return the portions to the initial position after the applied pressure is removed. Further provided are spring limiting devices that inhibit and limit return movement. One of the disadvantages of this trash can is that most of the compressed waste expands again without pressure application. It is less likely and unsanitary to remove at least a portion of the compressed refuse from the trash can.

It is known from KR 2013/0019692A to include a waste system for holding one of the frames of a garbage bag. A frame including a lower frame and an upper frame, including a support frame between them, can accommodate and clamp a trash bag in an opening. A hinged cover for closing the opening is arranged on the fastening ring. Inside it, the lid has a means for compressing the filled waste. Specifically, a plate is disposed inside the cover, the plate has a spring action and the plate pushes the waste down when the cover is closed so that the inside of the cover is kept at a certain distance from the surface of the garbage. The waste system only allows a limited compression of the filled waste, as the applied pressing force is only produced by the weight and spring force of the plate.

It is an object of the present invention to provide a garbage bag holding device in which the filling garbage can be compressed, and the garbage bag is not subjected to a tensile stress during compression, and the compressive force for compressing the garbage is applied. Maintain a certain period of time.

According to the invention, this object is solved by virtue of the features of the characterizing part of the first aspect. Further embodiments of the invention are within the subject matter of the appended claims.

The garbage bag holding device according to the present invention includes at least one guide bar, a base is disposed at a lower end thereof, and a bag holder is disposed at an upper end thereof. At least one container is implemented on the bag holder such that the bag holder is movable along at least one of the guide bars. The at least one guide rod is preferably movably received in the at least one container. In the alternative, the container may be embodied such that it is movably received in at least one of the guide bars. In particular, the bag holder can be in the direction of the base to One less guide moves. The movement of the bag holder in the direction of the base resists one of the forces acting in the opposite direction. A reaction can be generated by the garbage filled into the garbage bag. The reaction force can additionally be produced by means of a spring element arranged on at least one of the guide rods. For example, at least one compression spring can surround at least one of the guide bars. In the alternative, the at least one guide rod may have an open annular cross section, for example at least one compression spring is received in the cross section. In the alternative, at least one of the guide rods can also be embodied as a gas pressure spring element. However, the garbage to be compressed has already produced some reaction.

The holding device according to the invention preferably comprises a guide rod, preferably comprising two guide rods. The base can for example be implemented as a plate or a ring. The base and the at least one guide rod may be integrated.

A stop is provided at the upper end of the at least one guide bar that limits movement of the bag holder along at least one of the guides to the top. The upper stop further prevents the bag holder from being displaced all the way to the top, and by virtue of the force acting opposite the movement (i.e., a reaction force), at least one of the guide rods slides out of the container on the bag holder. The stop member can thereby be integrally molded to the at least one guide rod, can be connectable to one of the at least one guide rod, preferably can be tightened, and/or can be fastened to the One of the at least one guide rod, a screw, or the like, or one of the at least one of the guide rods inserted into one of the holes.

The bag holder further has an opening in which a trash bag can be fastened with its open edge. This opening can be closed by means of a cover. This cover is movably arranged on the bag holder, for example pivotally hinged or displaceably guided. For example, an edge that extends upwardly and only partially surrounds one of the openings can be disposed along the opening on the bag holder. The edge can have a structure. Thus, the upper end of the edge may have a bead, such as a flange. However, other designs such as grooves are also possible, particularly molded to accommodate, for example, a rubber ring. To secure a trash bag to the opening, the open edge is placed around the edge and secured to the edge, for example by means of a rubber ring. In the alternative, a correspondingly formed clamping frame can also be placed around the edge of the arranged opening of the garbage bag so that The garbage bag is arranged to be fixed between the edge and the clamping frame.

The opening may be further limited in its diameter such that a boundary surface that extends at least partially around the opening and most horizontally extends relative to the contents of the trash bag. Garbage that is prevented from overflowing from the opening can thus be filled into the area of the trash bag, which area is at least partially limited to the top by virtue of the boundary surface.

The lid that cooperates with the bag holder, for example, pivotally hinges and closes the opening, thereby also preventing an unpleasant odor caused by the waste filled in the garbage bag. In one embodiment, the lid is received by the hinge on the bag holder, wherein the lid is pivotable about a pivot by more than 90°, preferably up to 180°, such that the opening is sufficiently open for filling the trash. The position of the hinge on the bag holder is specifically positioned opposite the at least one guide bar.

The holding device is designed to provide at least one locking device. In one aspect, the at least one locking device allows the cover to be secured in a closed position on the bag holder, and on the other hand, the at least one locking device locks the bag holder along the at least one guide In a position. Accordingly, at least one locking device can be disposed on the cover to lock the bag holder and the cover in a closed position in a position along one of the at least one guide bar. The locking device can thereby comprise a locking pin engageable with the at least one guide rod in an extended position, for example with a recess or pawl disposed therein. In the alternative, at least one of the elements for securing the lid to the bag holder can be provided, for example, in the form of a locking pin, a hook or the like that can be engaged with one of the containers implemented on the lid. A further locking device can then be provided on the bag holder such that the locking device secures the bag holder to the at least one guide bar in an engaged position. An alternative locking device can also be secured to the base in the form of an elongate connecting member and can have a hook on one of the free ends that engages a corresponding recess on the cover. Thus, the cover can be held in the closed position and the bag holder can be held in a position along at least one of the guide bars.

The garbage bag holding device provides compression of one of the garbage filled into the garbage bag. For this purpose, a compressive force is applied from the top to the lid in the closed position such that the bag holder and the trash bag fastened to the bag holder are along at least one of the forces in the direction of the base opposite the reaction force The guide moves. The compressive force can be applied, for example, by hand or foot, or by a person's own weight in a vertical direction on the closure cap. For example, one of the protrusions by which the foot can apply pressure can thus also be implemented on the bag holder such that the bag holder is displaced along the at least one rail in the direction of the base. The waste filled into the garbage bag is thereby compressed between the cover and the base. Therefore, the garbage bag is not affected by a tensile stress. The garbage filled into the garbage bag is compressed, and the garbage does not come into contact with the hands or feet and does not use a large number of pressing devices. If the pressure application on the closure cap is released, the bag holder moves at least partially along at least one of the guide bars into an initial position and stops at the upper end of the at least one guide bar due to the force acting in the opposite direction.

Therefore, even if the applied compressive force no longer functions, the garbage is still in a compressed state in the garbage bag, which requires at least maintaining the compressive force until the internal stress of the garbage is greatly reduced or until the corresponding refuse material is at least partially plastically deformed. Therefore, it is possible to achieve this required pressing time, the bag holder being fixed to the at least one guide by means of a locking device in a compressed position and a cover in the closed position, in particular, depending on the The amount of garbage filled changes.

In order to release the bag holder from the compressed position, a compressive force can be applied to the cover again in the vertical direction, and the lock can be unlocked or locked or released, so that the bag holder moves to the initial position at the upper stop. in. The compressed trash in the trash bag is still mostly compressed so that one of the volumes used to fill the trash is again available in the trash bag. The filled waste can be compressed by this process (ie, by the downward movement of the bag holder and the closure cap to compress the trash, lock the bag holder in a compressed position, and release the lock after a certain period of time, so that the most Good use One volume provided by the garbage bag) is permanently compressed to a large extent. Surprisingly, it was observed that significantly more waste volume could be filled into the trash bag and part of the waste volume was filled into the trash bag more times.

The holding device according to the invention is particularly suitable for garbage bags having a certain volume, which is common for the family.

A simple system that can manage, or otherwise limit, the volume of one of the garbage bags without an additional garbage container is provided with a compressible garbage bag holding device according to the present invention. The trash bag is further unaffected by tensile stress during a compression process, reducing the risk of the trash bag tearing under stress. In the case of a holding device according to the invention, the compressive force that must be applied for compressing the trash can be applied by manpower or by weight, for example, such that a person pushes the closure cap and thus the trash bag with the foot or by hand.

The trash bag can be initially separated from the bag holder by using the entire volume-filled volume, can be closed, and can then be removed from the garbage bag holding device. For example, it can be removed from the trash bag holding device in a direction that is positioned opposite the at least one guide.
