Description

  The present invention relates to a trash bag for storing trash, and in particular, prevents rupture when compressed by a loading device of a trash truck so that a rupture sound is not generated and trash and sewage are not scattered. And a garbage bag that keeps animals such as dogs, cats and crows away.

  Garbage discharged from ordinary households, restaurants, business establishments, etc. is stored in garbage bags and collected in the garbage collection area designated for each region, and is equipped with a loading device as shown in FIG. It is collected by a mechanical truck called a backer truck. When the garbage bags are loaded on the backer truck, the garbage bags are compressed by the press plate of the loading device to reduce the bulk, and then sent into the loading device.

  Garbage bags usually used in ordinary households are made of a film material made of synthetic resin such as polyester. After the garbage is contained, the opening is tied or stringed to prevent the contained garbage from coming out. It is sealed and used with tape or the like. However, since a synthetic resin garbage bag generally does not have air permeability, the inside of the garbage bag is sealed when sealed. For this reason, if the sealed garbage bag is compressed with the press plate of the backer car, the air inside the garbage bag is not discharged to the outside, so the garbage bag will rupture at the end, which may cause a loud burst sound. In addition, internal garbage and sewage splashed around, causing discomfort to the surrounding residents, and sanitary conditions around the garbage collection site.

  In view of these circumstances, there has been proposed a garbage bag that can be evacuated from the air in a sealed state. For example, it is formed into a rectangular bag body using a non-breathable material such as a synthetic resin sheet. The one side is an opening, and the other side of the opening facing the opening is provided with a plurality of fusion missing portions along the side, spaced apart from each other. However, there is a publicly known garbage bag provided with a gap in the length direction (see Patent Document 1).

  However, while the above-described garbage bag can be used to deaerate the air inside, the construction is complicated, so that it takes time and effort to produce it. In addition, when garbage containing moisture such as raw garbage is accommodated, there is also a problem that water flows out from the fusion missing portion.

On the other hand, if you put a garbage bag containing garbage in the garbage collection area, animals such as stray dogs, stray cats, and crows will break the garbage bag and scatter the garbage, making the surrounding environment unsanitary and collecting garbage. After that, it was complicated to clean the collection place.

  Further, the means adopted by the invention of claim 6 is the garbage bag 10, wherein the animal repelling means 14 is an animal repelling hologram 14 provided on the surface of the bag material 11. By providing the hologram 14 on the surface of the bag material 11, animals such as dogs, cats and crows can be visually threatened.

  According to the garbage bag of the first aspect, since the bag is formed of the bag material having the vent hole, the air inside the garbage bag is discharged to the outside through the vent hole when compressed by the loading device of the garbage truck. Therefore, the garbage bag is prevented from rupturing, and it is possible to prevent the generation of a burst sound and the scattering of dust and sewage. In addition, since the animal repelling means is provided, the animal does not catch the garbage bag.

  According to the garbage bag according to claim 2, in addition to the effect of the garbage bag according to claim 1, the ventilation bag is provided in the vicinity of the opening portion of the bag material, so that the garbage bag is slanted in a state in which the garbage is accommodated. Even if it is tilted, sewage collected inside the garbage bag does not leak out through the vents, so care is not taken in handling.

  According to the garbage bag of Claim 3, in addition to the effect of the garbage bag of Claim 1 or 2, the garbage bag was compressed by forming the bag material from the liquid-impermeable and air-permeable microporous film. Sometimes, while holding the moisture in the garbage bag, only the air passes through the bag material and is discharged to the outside, so it is possible to more efficiently discharge the air in the garbage bag in combination with the vent hole. It can be carried out.

  According to the garbage bag according to claim 4, in addition to the effect of the garbage bag according to any one of claims 1 to 3, the animal contains garbage repellent as an animal repelling means in the bag material, so that the animal becomes garbage. The animal's olfactory and taste are stimulated by animal repellents when the garbage bags are approached or breached in an attempt to catch the garbage in the bags, so animals learn the functions of animal repellents and use the garbage bags. You won't catch trash around the fish.

  According to the garbage bag according to claim 5, in addition to the effect of the garbage bag according to any one of claims 1 to 4, an animal repellent is attached to the surface of the bag material as an animal repelling means. When an animal approaches the garbage bag or breaks it while trying to catch the garbage in the garbage bag, the animal repellent adheres to the mouth and body of the animal and strongly stimulates the animal's olfaction and taste. Learn the functions of animal repellents, no longer catch garbage around the garbage bags.

  According to the garbage bag according to claim 6, in addition to the effect of the garbage bag according to any one of claims 1 to 5, a hologram is provided on the surface of the bag material as animal repelling means, so that dogs, cats, crows, etc. This will visually intimidate the animals and keep them away from the trash bags, so animals will not catch trash bags and scatter trash around them. Moreover, since the color of the reflected light can be changed in a complex manner depending on the viewing position and angle, the hologram can be repulsed for a long time without getting used to the animal.

  The garbage bag according to the present invention is composed of a bag material provided with vent holes, and is provided with animal repelling means on this bag material.

  As the bag material, those conventionally used for garbage bags can be used. For example, a bag material made of a film material made of polyolefin resin such as polyethylene or polypropylene can be used. Among them, it is preferable to use a bag material made of a liquid-impermeable and air-permeable microporous film that can pass only gas without passing liquid.

  As the liquid-impermeable and air-permeable microporous film, those conventionally used for sanitary products, food packaging materials, house wrap materials, etc. can be used. For example, polyolefin-based resins such as polyethylene and polypropylene are inorganicly filled. After the agent is mixed and formed into a sheet by the T-die method, inflation molding method, etc., it is stretched uniaxially or biaxially to cause interfacial delamination between the filler and the polyolefin resin. What is produced by generating voids, or by filling the resin adhesive with a heat-vaporizable filler and molding the sheet, the filler is vaporized by the heat at the time of forming the sheet and disappeared Examples thereof include a number of micropores present after the agent in the sheet.

  Further, it is preferable to use a bag material having flexibility so that it can be easily sealed by tying or tying the opening, and having a mechanical strength that does not easily break.

  When a non-porous bag material is used, a vent hole is provided after bag making. The vent hole may be anything as long as it allows the air inside the bag to be discharged more efficiently when the garbage bag is compressed. For this reason, the air holes can be provided in the bag material by, for example, needle punching, corona discharge, laser processing, or the like. The number, size, and shape of the air holes are not particularly limited, but the air holes are efficiently evacuated and formed to have a size and number enough to hold the stored dust. Good. Furthermore, the vent hole is preferably provided in the vicinity of the opening of the bag material. By providing a ventilation hole near the opening, even if the trash bag is tilted obliquely in a state where trash is stored, the sewage collected at the bottom of the trash bag will be released through the ventilation hole. It is because it does not leak out.

  Moreover, the garbage bag of this invention has provided the animal repelling means in the bag material. As one form of the animal repelling means, for example, a form in which an animal repellent is contained in the bag material can be taken. In the case of this form, since the bag material contains an animal repellent, the taste and smell that the animal dislikes are emitted from the garbage bag, and the animal can be kept away from the garbage bag.

  The animal repellent contained in the bag material is not particularly limited. For example, d-limonene, caprinaldehyde, caprylaldehyde, silitol, which have been confirmed to have a repellent effect on dogs, cats, pigeons, crows, etc. Essential oils such as orange peel oil, lemon oil, bergamot oil, sea bream oil, peppermint oil, turpentine oil, camphor oil, etc., pungent ingredients of acetic acid, mustard or wasabi, capsaicin, denatonium benzoate These can be used alone or in combination of two or more.

  The animal repellent is kneaded at the stage of the material before forming the bag material. At this time, the animal repellent may be kneaded directly into the material of the bag material, or the animal repellent may be enclosed in microcapsules or kneaded in dextrin.

  The animal repellent as an animal repelling means can also take the form adhered to the bag material surface. By attaching the animal repellent to the surface, when the animal approaches the garbage bag and eats it while trying to catch the garbage in the garbage bag, the animal repellent adheres to the animal's mouth and body, The olfactory sense and taste can be stimulated more strongly. The animal repellent to be attached to the surface can be attached to the front side surface, the back side surface or both sides of the bag, and the same material as that contained in the bag material may be applied directly, or It may be enclosed in a capsule or encapsulated in dextrin.

  In addition, as a form of adhesion of animal repellent to the bag material surface, when printing a mark or product name on the bag material surface, animal repellent is included in the printing ink, A product name or the like printed at the same time as an animal repellent adhered to the bag material surface can be mentioned. In this case, the printing on the surface of the bag material itself has an animal repelling function.

  Also, as another animal repelling means, visually intimidating and avoiding animals approaching the garbage bag, specifically, patterns that are disliked by animals such as mesh patterns and eyeball pictures displayed on the bag surface, A figure or a picture can be mentioned. In particular, the animal repelling hologram has an excellent effect of visually intimidating and avoiding animals approaching the garbage bag.

  A hologram is obtained by irradiating a recording object with object light and reference light, superimposing two lights on a recording material, and developing the recording material. In the recording material, 1000 to 7000 interference fringes are formed in 1 mm width by the object light and the reference light, and the light propagated from the object is frozen and recorded on the recording material. Can be viewed three-dimensionally. Furthermore, the hologram has a feature that when a viewing position is moved, a three-dimensional image viewed from that direction can be seen. Therefore, when a hologram is provided, the color of the reflected light can be changed in a complex manner depending on the viewing position and angle, so that the complicated reflected light can be emitted.

  The hologram may be provided directly on the surface of the bag material, or a hologram sheet may be separately prepared and provided on the surface of the bag material. There are many types of holograms to be used, such as a master hologram, a Lippmann hologram, and a rainbow hologram. However, the type of hologram is not particularly limited and may be appropriately selected and used.

  In addition, as a form of the garbage bag of the present invention, an animal approaching the garbage bag is visually observed in a bag material containing and / or adhering an animal repellent as an animal repelling means in the bag material and / or on the surface of the bag material. It is also possible to provide an animal repelling means that threatens and avoids. In this case, the animal repelling effect can be further enhanced.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the garbage bag 10 is formed from the bag material 11 which consists of a liquid-impermeable air-permeable microporous film. The bag 11 is made by mixing polyethylene with an inorganic filler, lemon oil and capsaicin as animal repellents, forming into a cylindrical film, and then stretching the liquid. It has the property of allowing only air to pass therethrough. A plurality of vent holes 13 are formed by needle punching at a position slightly below the opening 12 of the bag material 11. An animal repellent consisting of a mixture of lemon oil and capsaicin is applied to the surface of the bag material as animal repelling means.

  Further, a hologram 14 is provided on the surface of the garbage bag 10 as another animal repelling means. The hologram 14 is formed in an eyeball pattern that is said to have a repelling effect on birds such as crows, and is provided by being directly printed on the surface of the bag material 11.

  As shown in FIG. 2, the garbage bag 10 according to the present embodiment is used by sealing the opening 12 after accommodating the garbage, as in a general garbage bag. As shown in FIG. 3, when compressed by a press plate of a backer car, the air inside the trash bag 10 is formed in the air holes 12 and the microholes formed in the bag material 11 constituting the trash bag 10. So that the garbage bag does not rupture and no bursting sound is generated, and the garbage inside does not scatter.

  Further, when the garbage bag 10 is placed at the garbage collection place, the holograph 14 displayed on the surface of the animal such as a crow can threaten the animal such as the crow and prevent the animal from approaching the garbage bag 10. When the garbage bag 10 is broken to try to catch the garbage inside, the animal repellent that is contained in the bag material 11 and applied to the surface of the mixture of lemon oil and capsaicin strongly enhances the taste and smell of the animal. It will irritate. As a result, the function of the animal repellent is learned, and it gradually keeps away from the garbage bag.
