However, since the cartridge main body is formed in a hollow cylindrical shape, in a construction site where a large amount of sealing material is used. The used cartridge becomes bulky at the storage location, and this bulkiness becomes a problem when it is discarded. Moreover, even if it tries to recycle as a plastic material, since it is bulky when collect | recovering, transportation efficiency is bad, and recycling is not implement | achieved at present. Therefore, if the used cartridge body is disassembled by crushing or cutting to reduce the volume, it can be efficiently stored and transported. However, since the cartridge body is often a plastic molded product, the cartridge body Cannot be easily disassembled, and the volume of the cartridge body after use cannot be sufficiently reduced.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a cartridge for a sealing material that can easily disassemble a used cartridge body.

In order to achieve the above-mentioned object, the present invention has a cartridge main body formed integrally with one end of a cylindrical barrel portion and a cartridge main body formed with a sealing material discharge port, and is fitted on the other end side of the barrel portion. In the cartridge for sealing material, wherein the sealing material in the cartridge body is discharged from the discharge port of the lid portion by pressing the plunger and moving the plunger toward one end side of the cartridge body. A pair of first groove portions extending from one end side of the cartridge body to the other end side and spaced apart from each other in the circumferential direction of the barrel portion are provided at predetermined locations in the circumferential direction of the barrel portion, and on the lid portion side of the barrel portion. A second groove extending in the circumferential direction of the body is provided so that one end is continuous with one first groove and the other is continuous with the other first groove. The thickness of the body Is formed smaller than min, band portion between the lid by pulling towards the one end of the body portion is separated from the second groove leaving a circumferential portion on the other end, each first groove Is configured to be separated from the body portion integrally with the lid portion .

  As a result, the lid portion of the used cartridge body is separated from the second groove portion while leaving a part in the circumferential direction (a portion without the second groove portion), and the lid portion is pulled toward the other end side of the barrel portion. However, the cartridge main body is disassembled by separating the portion between the first groove portions from the first groove portions, removing the lid portion from the body portion, and separating the body portion in the circumferential direction. At that time, since the thickness of the body portion in each groove portion is smaller than the other portions, for example, the lid portion can be bent sideways or cut with a cutter along the second groove portion. The part can be easily separated from the second groove part.

  According to the present invention, the cartridge body can be easily disassembled by separating the lid portion of the cartridge body from the second groove portion and separating the body portion from the first groove portion, and the body portion can be Therefore, another cartridge body can be inserted into the cartridge body with the body portion opened in the circumferential direction, and a plurality of cartridge bodies can be stacked in an orderly manner. As a result, the volume of the cartridge body after use can be reduced, so that it can be efficiently stored and transported at a construction site, for example, and the amount (volume) of industrial waste can be reduced. Furthermore, since the collection efficiency can be improved by volume reduction, the cost for recycling can also be reduced.

  This sealing material cartridge comprises a plastic cartridge main body 1 filled with the sealing material A and a plunger 2 for pushing the sealing material A in the cartridge main body 1 to the outside. The nozzle 3 is detachably attached.

  The cartridge body 1 includes a cylindrical body portion 1a and a lid portion 1b integrally formed at one end of the body portion 1a. The discharge port 1c for discharging the sealing material A to the lid portion 1b. Is provided. The discharge port 1c is formed so as to protrude in a cylindrical shape, and the nozzle 3 is screwed onto the outer peripheral surface thereof. In addition, a pair of first groove portions 1d extending from one end side to the other end side of the cartridge body 1 are provided on the outer peripheral surface of the barrel portion 1a, and the first groove portions 1d are in the circumferential direction of the barrel portion 1a. Are provided at intervals. A second groove 1e extending in the circumferential direction of the body 1a is provided on the lid 1b side on the outer peripheral surface of the body 1a. One end of the second groove 1e is one first groove 1d. Is formed so that the other end is continuous with one end of the other first groove portion 1d. As shown in FIG. 4, the groove portions 1d and 1e are formed in a V-shaped cross section, and the thickness of the body portion 1a of the portion where the groove portions 1d and 1e are formed is smaller than the other portions. In this case, the groove portions 1d and 1e are preferably formed in a V-shaped cross section so that they can be easily separated, but other shapes may be used, and only one of the groove portions 1d and 1e has a V-shaped cross section. You may make it form. In this case, it is preferable to use soft polyethylene (PE) as the material of the cartridge body 1. Further, as shown in FIG. 2, the cartridge body 1 is formed such that the first groove 1d does not exist for a predetermined length L (for example, 3 mm) from the other end of the body 1a toward the one end. That is, the first groove portion 1d is provided from one end of the trunk portion 1a to slightly before the other end (position of the length L from the other end). Moreover, the film 4 made from aluminum is affixed on the back side of the cover part 1b, and the discharge outlet 1c is closed by the film 4 from the inner side.

  The plunger 2 is made of a circular member having an outer diameter equivalent to the inner diameter of the barrel portion 1a, and is inserted into the other end side of the barrel portion 1a so as to be movable in the axial direction of the cartridge body 1.

  When the sealing material cartridge configured as described above is used, the film 4 is broken to open the discharge port 1c, and the nozzle 3 is attached to the discharge port 1c and is mounted on a dedicated device (not shown). When discharging the sealing material A from the cartridge main body 1, a necessary amount of the sealing material A is pushed out from the discharge port 1 c of the cartridge main body 1 by pressing the plunger 2 with an instrument.

  Further, after using the sealing material A of the cartridge main body 1, the barrel portion 1a and the lid portion 1b of the cartridge main body 1 are separated from the first and second groove portions 1d and 1e, and the plunger 2 is inserted from the barrel portion 1a. The cartridge body 1 is disassembled by removing the cartridge. That is, as shown in FIG. 5, the lid portion 1b is separated from the second groove portion 1e, thereby separating the lid portion 1b from the body portion 1a leaving a part in the circumferential direction (a portion without the second groove portion 1e). In this case, since the thickness of the body portion 1a is smaller than the other portion in the portion where the second groove portion 1e is formed, for example, the nozzle is gripped and bent sideways, or the second groove portion 1e is formed in the second groove portion 1e. The lid 1b can be easily separated from the second groove 1e by cutting along the cutter. Next, as shown in FIG. 6, by pulling the lid portion 1b from one end side to the other end side of the body portion 1a, the belt-like portion 1a 'between the first groove portions 1d is integrated with the lid portion 1b. Separate from part 1a. In this case, since the thickness of the body portion 1a is smaller than the other portions in the portions where the first groove portions 1d are formed, the belt-like portion 1a 'between the first groove portions 1d is removed from the body portion 1a. Easy to separate. Then, when the belt-like portion 1a ′ is completely cut to the other end of the body portion 1a, the lid portion 1b and the belt-like portion 1a ′ are removed from the body portion 1a, and the body portion 1a becomes each first groove portion as shown in FIG. Separated from 1d in the circumferential direction. In addition, although there is a portion where the first groove portions 1d are not formed on the other end side of the body portion 1a, this portion has a slight length (for example, 3 mm), and therefore, together with each first groove portion 1d. It can be easily broken. Then, by inserting another cartridge main body 1 into the cartridge main body 1 in a state where the peripheral surface of the body portion 1a is open, a plurality of cartridge main bodies 1 can be arranged in an orderly manner as shown in FIG.

  As described above, according to the sealing material cartridge of the present embodiment, the pair of circumferential first pairs extending from one end side to the other end side of the cartridge body 1 at a predetermined position in the circumferential direction of the body portion 1a of the cartridge body 1. While providing the groove part 1d, the circumferential direction of the trunk part 1a is such that one end side is continuous with one first groove part 1d and the other end is continuous with the other first groove part 1d on the lid part side 1b of the trunk part 1a. The second groove portion 1e extending over the first groove portion 1e is formed, and the thickness of the body portion 1a in each groove portion 1d, 1e is made smaller than that of the other portions. While separating from 1e, pulling the cover part 1b toward the other end of the body part 1a, the band-like part 1a 'is separated from each first groove part 1d, and the cover part 1b is removed from the body part 1a. By separating the la in the circumferential direction, The ridge body 1 can be easily disassembled. Further, since the body portion 1a can be separated in the circumferential direction, another cartridge body 1 can be inserted into the cartridge body 1 in a state where the body portion 1a is opened in the circumferential direction. It can be neatly superimposed. Thereby, since the volume reduction of the cartridge main body 1 after use can be achieved, storage and transportation can be performed efficiently, and the amount (volume) of industrial waste can also be reduced. Furthermore, since the collection efficiency can be improved by volume reduction, the cost for recycling can also be reduced. Furthermore, since the barrel portion 1a can be separated in the circumferential direction, the plunger 2 in the cartridge body 1 can be easily taken out, which is extremely advantageous when sorting.

  Further, since the cartridge body 1 is formed so that the first groove portion 1d does not exist for a predetermined length L from the other end of the barrel portion 1a toward the one end side, an internal pressure is applied to the barrel portion 1a by the pressing of the plunger 2. Even in this case, the crack from the other end of the body 1a to the first groove 1d is not generated. Thereby, the strength of the cartridge main body 1 can be sufficiently secured during use, which is effective in preventing the cartridge main body 1 from bursting.

  Furthermore, since each groove part 1d, 1e was formed in V-shaped cross section, stress can be concentrated on the bottom part of each groove part 1d, 1e, and the trunk | drum 1a can be reliably isolate | separated from each groove part 1d, 1e. .

  In the above embodiment, the first groove portion 1d is formed so as not to exist for a predetermined length L from the other end of the body portion 1a toward the one end side. One groove portion 1d may be formed.
