JP7418161B2 - Packaging bag for pet urine disposal material - Google Patents

Description

The present invention relates to a packaging bag for pet urine disposal materials.

As a urine disposal material for pets, especially a urine disposal material for cats, the one described in Patent Document 1 is known, for example.
Patent Document 1 discloses that by containing two types of clay minerals with different properties and a predetermined phosphorus atom-containing component in a predetermined ratio, the amount of solidification is small and there is no stickiness even if the amount of minerals used is reduced. It is described that the deodorizing properties of ammonia odor can be improved without forming lumps and deteriorating the deodorizing properties of mercaptans.

A general method of using pet urine disposal materials will be explained. First, pour the treatment material sealed in a packaging bag into a toilet container placed on the ground, and every time your pet urinates, remove the agglomerated and solidified material (treatment material that has absorbed urine and solidified) with a shovel, etc. , the amount of processing material used for coagulation and solidification is poured in to replenish the reduced amount of processing material. Regarding the timing for owners to replenish the treatment material, from the viewpoint of hygiene for the owner and pet, and from the viewpoint of preventing the occurrence of bad odors caused by urine, it is recommended that the owner replenish the treatment material every time they normally urinate (or every time they urinate infrequently). However, it is being done. The amount of treatment material to be replenished is adjusted depending on the composition of the raw material of the urine treatment material used, but for example, the mass of the treatment material itself used for one urination and discarded (the mass without urine) ) is generally about 5g to 50g. Therefore, the owner replenishes a relatively small amount of treatment material (for example, about 10 to 100 g for one or two urinations) each time the pet urinates.

Such pet urine disposal materials are generally sold in a form sealed in a packaging bag, and the volume of the bag is usually large (for example, 5 to 10 liters).

JP 2019-24429 Publication

When a large capacity pet urine disposal material (hereinafter also simply referred to as "urination disposal material") is enclosed in a packaging bag, it becomes heavy and difficult to transport. Therefore, considering the convenience of transportation, we investigated packaging bags equipped with grips.
When I placed the urine disposal material in a packaging bag with a grip, held the grip with one hand, and poured it into a toilet container placed on the ground. In some cases, the tube bends, making it difficult to pour in the desired amount of treatment material (for example, the amount used for one urination and discarded). Particularly, when the amount of urine treatment material in the packaging bag decreases, the lower part of the bag tends to bend, which sometimes makes it difficult to pour in the desired amount of urine treatment material. In addition, when pouring urine disposal material into a toilet container placed on the ground, the work is often done in a bent position, so it is easier to pour the desired amount of urine disposal material into the toilet container. There is a possibility that it may not be possible.

An object of the present invention is to provide a packaging bag for pet urine disposal material with a grip, which allows the user to easily pour a desired amount of urine disposal material into the packaging bag, regardless of the amount of urine disposal material in the packaging bag.

Examples of such a laminated film include a laminated film including a base layer disposed on the outside and a sealant layer disposed on the inside. The laminated film may be one in which an intermediate layer is provided between the base layer and the sealant layer.

The base material layer may include polyesters such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and polybutylene terephthalate (PBT), polyolefins such as polyethylene (PE), polypropylene (PP), and polystyrene (PS), and nylon. -6, polyamide (PA) such as nylon-66, polycarbonate (PC), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polyvinyl alcohol (PVA), ethylene - Stretched or unstretched films made of materials such as vinyl alcohol copolymer (EVOH), polyethersulfone (PES), and polymethyl methacrylate (PMMA). Among these, stretched or unstretched films made of polyamide are preferred.

As a sealant layer, low-density polyethylene resin (LDPE), medium-density polyethylene resin (MDPE), high-density polyethylene resin (HDPE), linear low-density polyethylene resin (LLDPE), polypropylene resin (PP), ethylene-propylene resin, etc. Polymer (EP), ethylene-α olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-methacrylic acid ester copolymer, ethylene-acrylic acid ester Examples include resins such as copolymers, ionomer resins, ethylene-vinyl acetate copolymers (EVA), and films formed from these resins. Among these, linear low density polyethylene resin (LLDPE) is preferred.

Examples of the intermediate layer include those similar to the films exemplified as the base layer. The method for laminating these layers is not particularly limited, and can be laminated by commonly used methods such as dry lamination and extrusion lamination (including sandwich lamination).

When using a laminated film as the film, the thickness of the base layer is preferably 5 μm or more, more preferably 7 μm or more, even more preferably 10 μm or more, and preferably 40 μm or less, more preferably 30 μm or less, and even more preferably 20 μm or less.

The content of the packaging bag is preferably 2 liters or more and 10 liters or less. The content capacity of the packaging bag is more preferably 2.5 liters or more, still more preferably 3 liters or more, and more preferably 8 liters or less, still more preferably 6 liters or less. By setting the content of the packaging bag within the above-mentioned range, it becomes easier to transport and pour the desired amount of urine treatment material into the toilet container.

The mass of the contents of the packaging bag is preferably 1 kg or more and 10 kg or less. The mass of the contents of the packaging bag is more preferably 1.5 kg or more, still more preferably 2 kg or more, and more preferably 8 kg or less, still more preferably 6 kg or less. By setting the mass of the contents of the packaging bag within the above range, it becomes easier to transport and to pour the desired amount of urine treatment material into the toilet container.

[Urine treatment material]
The pet urine disposal material that is the contents of the packaging bag is not particularly limited, but includes, for example, materials made from clay, wood, paper, and the like. Specifically, for example, toilet sand described in Patent Document 1 (pet litter containing two types of clay minerals with different properties and a predetermined phosphorus atom-containing component in a predetermined ratio), bentonite, Examples include corn cob flour and toilet litter containing a binding agent.

The shape of the urine treatment material is not particularly limited, and examples include spherical, cylindrical, flaky, corrugated plate, and pellet shapes. Among these, from the viewpoint of ease of pouring into a toilet container and handling, cylindrical or pellet-shaped ones are preferred, and cylindrical ones are more preferred.

When the urine treatment material has a cylindrical shape, the diameter is preferably 2 mm or more and 10 mm or less. In this case, the length of the urine treatment material is preferably 2 mm or more and 30 mm or less, more preferably 3 mm or more and 25 mm or less, and still more preferably 4 mm or more and 20 mm or less. The diameter of the cylindrical urine disposal material means the diameter of the circular surface, and the length of the urine disposal material means the length of the side surface.

The bulk density of the urine treatment material is preferably 0.1 g/cm ³ or more, more preferably 0.15 g/cm ³ or more, even more preferably 0.2 g/cm ³ or more, and preferably 1.0 g/cm ³ Below, it is more preferably 0.95 g/cm ³ or less, still more preferably 0.9 g/cm ³ or less. By setting the bulk density of the urine treatment material within the above range, it becomes easier to pour a desired amount of the urine treatment material into the toilet container.

The bulk density of the urine disposal material can be determined, for example, by placing a sample in a container of a specific capacity, scraping the top surface horizontally, and measuring the weight of the sample.

The angle of repose of the urine treatment material is preferably 30° or more and 80° or less. The angle of repose of the urine treatment material is more preferably 35° or more, and more preferably 75° or less. By setting the angle of repose of the urine treatment material within the above range, it becomes easier to pour a desired amount of the urine treatment material into the toilet container. Generally, the size of urine disposal materials made from clay tends to be small, and its angle of repose is 30° or more and less than 50°, while the size of urine disposal materials made from paper tends to be larger. The angle of repose is 50° or more and 80° or less.

The angle of repose of urine treatment materials tends to differ depending on the raw material; for example, those made from paper tend to have a larger angle of repose than those made from clay.

The angle of repose can be measured by the following method.
Place a measuring device with a horizontal lid and an angle scale on a flat surface, and with the side lid of the measuring device closed, pour the urine disposal material from the top of the measuring device. Fill it up to the specified position in a heaping manner. Next, the side lid is gently opened and the filled urine treatment material is naturally discharged by gravity. Thereafter, the angle of repose (°) can be measured by reading the angle (angle of inclination) between the surface of the urine treatment material remaining in the measuring device and the horizontal plane from the scale.

[Cut line]
A tear line 30 is provided at one corner of the upper left side of the packaging bag 10. The perforation line 30 is a spout-forming perforation line that is cut to form the spout 31 (see FIG. 3).

The packaging bag 10 may be processed at a position corresponding to the perforation line 30 to facilitate cutting (for example, a half-cut line, a half-blanking process, etc.). Furthermore, a notch, a slit, or the like may be provided at one end of the perforation line 30 in order to easily form a starting point for cutting.

In the present invention, the angle θ1 between the perforation line 30 and the upper side of the packaging bag 10 is 5° or more and less than 45°. By setting the angle θ1 between the cut line 30 and the top side of the packaging bag within such a range, it becomes easier to grasp the grip with one hand and pour the desired amount of urine disposal material into the toilet container. . The reason why the above effects can be obtained by setting the angle θ1 between the perforation line 30 and the upper side of the packaging bag within the above range is presumed to be due to the following reasons.
When the packaging bag 10 is cut along the perforation line 30 provided so that the angle θ1 with the upper side of the packaging bag 10 is 5° or more and less than 45°, a spout 31 is formed (see FIG. 3). When pouring the urine treatment material into the toilet container by grasping the grip with one hand, tilt the packaging bag 10 so that the spout 31 faces downward, and the spout 31 opens as shown in FIG. 4. It has a drop-like shape. In the spout 31 in the open state shown in FIG. 4, the widest portion 30M is located below the center of the spout 31 in the vertical direction, making it easy to adjust the amount of urine treatment material poured out. Further, when the angle θ1 is 5° or more and less than 45°, as shown in FIG. 1, the length of A2 is longer than the length of A1, so when pouring the urine treatment material, It is easy to see how the water is poured into the toilet container. As a result, it is presumed that by setting the angle θ1 between the perforation line 30 and the upper side of the packaging bag within the above range, it becomes easier to pour the liquid into the toilet container.

On the other hand, when the upper corner of the packaging bag 10 is cut along the cut line set so that the angle θ1 with respect to the upper side of the packaging bag is 45° or more to form a spout, the spout opens and becomes as shown in FIG. It has an elliptical shape. In the spout in the open state shown in FIG. 5, the maximum width portion 3M is located at or above the center of the spout in the vertical direction (direction connecting 3A and 3B), so that urine inside the packaging bag can be evacuated. When the amount of treatment material is large, more urine treatment material than desired is poured out from the spout, making it difficult to adjust the amount of urine treatment material poured out. Furthermore, in this aspect, when pouring the urine treatment material into the toilet container, it is difficult to see how it is being poured into the toilet container, making it difficult to adjust the amount of urine treatment material poured into the toilet container.

From the viewpoint of making it easier to pour the desired amount of urine disposal material into the toilet container, when the diameter of the urine disposal material is 2 mm or more and 10 mm or less and its angle of repose is 30° or more and less than 50°, Aspect (Aspect 1) in which the angle θ1 is 20° or more and less than 45°, and when the diameter of the urine treatment material is 2 mm or more and 10 mm or less and its angle of repose is 50° or more and 80° or less, the angle θ1 is 5°. An aspect (aspect 2) in which the angle is greater than or equal to 20° is preferable. In addition, in the case where the urine treatment material has a cylindrical shape and the diameter of the urine treatment material made from clay is 2 mm or more and 7 mm or less, an aspect (aspect 1) in which the angle θ1 is 20 degrees or more and less than 45 degrees. When the diameter of the urine treatment material made from paper is 4 mm or more and 10 mm or less, an aspect (aspect 2) in which the angle θ1 is 5 degrees or more and less than 20 degrees is preferable.

In the above aspect 1, the length of the unsealed portion of the perforation line 30 where the film is not sealed (the unsealed portion of the perforation line) is preferably 5 cm or more and 15 cm or less, more preferably 6 cm or more, and even more preferably The length is 7 cm or more, more preferably 14 cm or less, and even more preferably 13 cm or less. In the above aspect 2, the length of the unsealed portion of the perforation line 30 is preferably 5 cm or more and 15 cm or less, more preferably 6 cm or more, even more preferably 7 cm or more, more preferably 14 cm or less, and even more preferably 13 cm. It is as follows. In Aspects 1 and 2 above, when the length is 5 cm or more, it is possible to prevent the urine treatment material from clogging the spout even when the content is particularly large, and it becomes easy to pour in the desired amount. When the length is 15 cm or less, it is possible to prevent more urine treatment material from pouring out than the desired amount, and it becomes easy to pour in the desired amount. In this embodiment, "the length of the unsealed portion of the perforation line" corresponds to the length from 30A to 30B in FIG.

[Gripping part]
A grip portion 20 is provided at the top of the packaging bag 10. In this embodiment, the grip portion 20 is provided at one corner of the upper portion (the right corner in the figure) opposite to the corner where the perforation line 30 is provided (the left corner in the figure). By providing the grip portion on the opposite side to the perforation line 30, it becomes easier to pour the urine treatment material into the toilet container.

In this embodiment, the grip part 20 includes three circular holes 21, 22, and 23 (three or more circular holes). The circular shape of the gripping portion 20 increases the strength of the gripping portion and provides a good tactile sensation when the user inserts his/her hand into the gripping portion. Moreover, since the gripping part 20 includes three or more circular holes 21, 22, and 23, the pressure applied to the fingers when lifting the gripping part is dispersed, so that the burden on the fingers can be reduced.

The three circular holes 21, 22, and 23 are provided at intervals, and an unsealed portion is provided in a gap region 25 between adjacent circular holes. By providing an unsealed portion in the gap region 25 between adjacent circular holes, the unsealed portion stretches when a load is applied to the gripping portion, thereby suppressing the occurrence of tearing or tearing of the gripping portion. As a result, the strength of the grip portion 20 can be increased.

The size of the circular holes 21, 22, 23 is not particularly limited as long as it is large enough to fit a finger, but the diameter of the circular hole is preferably 15 mm or more, more preferably 18 mm or more, still more preferably 20 mm or more, and preferably is 40 mm or less, more preferably 35 mm or less, even more preferably 30 mm or less.

The three or more circular holes include end circular holes 21 and 23 provided at the ends, respectively, and a central circular hole 22 provided between the two end circular holes 21 and 23. As shown in FIG. 2, the central circular hole 22 is provided at a position where its center position 22P is offset from the line X1 connecting the center 21P of the end circular hole 21 and the center 23P of the end circular hole 23. . In this way, by providing the center circular hole 22 provided between the two end circular holes 21 and 23 at a shifted position, it is possible to grasp the packaging bag by inserting the fingers of one hand into the circular hole. In some cases, the packaging bag can be held in a stable state, making it easier to pour the urine treatment material into the bag.

The effects of this embodiment will be explained.
In this embodiment, the packaging bag for the pet urine disposal material is provided with a spout-forming perforation line 30 that is cut out to form the spout 31 at one corner of the top, and this perforation line 30 and the packaging bag The angle θ1 formed with the upper side of 10 is 5° or more and less than 45°. In this embodiment, when pouring the urine treatment material into the toilet container, if the packaging bag 10 is tilted so that the spout 31 faces downward, the spout 31 opens and assumes a shape as shown in FIG. Therefore, it is easy to adjust the amount of urine treatment material poured out, and it is easy to see how the urine treatment material is being poured into the toilet container when pouring the urine treatment material. As a result, according to the present embodiment, it is possible to easily pour a desired amount of urine treatment material into the packaging bag, regardless of the amount of urine treatment material in the packaging bag.

In this embodiment, the grip portion 20 is provided at one corner of the upper portion that is different from the corner where the perforation line 30 is provided. That is, in this embodiment, since the spout 31 and the grip part, which are formed by cutting the perforation line 30, are provided at the two corners of the upper part, the grip part 20 can be gripped with one hand. When the packaging bag 10 is lifted, the spout 31 side tilts downward (see FIG. 3). When the packaging bag is further tilted, the urine treatment material contained in the packaging bag 10 is poured out from the spout 31, making it easier to pour the urine treatment material into the toilet container.

Further, in this embodiment, the grip portion 20 includes three circular holes 21, 2, and 23 provided at intervals. According to this embodiment, since the shape of the grip part 20 is circular, the strength of the grip part 20 can be increased and the tactile sensation when the hand is inserted can be made good. Since the circular holes 21, 22, and 23 are included, the pressure applied to the fingers when lifting the grip portion 20 is dispersed, and the burden on the fingers can be reduced.

Furthermore, in this embodiment, an unsealed portion is provided in the gap region 25 between the adjacent circular holes 21, 22, and 23, so that the unsealed portion expands when a load is applied to the gripping portion 20. This prevents the grip portion 20 from tearing or tearing. As a result, according to this embodiment, the strength of the grip portion 20 can be increased.

Furthermore, in this embodiment, the central circular hole 22 among the three circular holes 21, 22, 23 is provided at a position offset from the line connecting the centers of the two end circular holes 21, 23. When the packaging bag 10 is gripped by inserting the fingers of one hand into the circular holes 21, 22, 23, the packaging bag 10 can be gripped in a stable state, making it easier to pour the urine treatment material. Become.
