Description

  The present invention relates to an extrusion gun for extruding the contents from a hard or soft container filled with a paste-like article, in particular, a highly viscous material mainly used in construction, such as a sealing material, an adhesive, etc. The present invention relates to an extrusion gun for extruding contents from a container.

  Conventionally, an extrusion gun is known as a tool for extruding contents from a container filled with a paste-like article. Typical examples of paste-like articles in which an extrusion gun is used include sealing materials and adhesives.

  As an extrusion gun for extruding the contents from a container filled with such a paste-like article, a sealing material or adhesive is filled in a cartridge made of a hard material such as paper or plastic, and is loaded into the extrusion gun and sealed. Cartridge-type extrusion guns that extrude materials are now widely used. As a cartridge type extrusion gun, for example, the applicant of the present application has already proposed the invention shown in Patent Document 1.

  However, when a cartridge type container using a hard material is used, there is a problem in that the volume and weight of the waste increase when the cartridge after the sealant or the like is extruded and used up is discarded.

  Therefore, a sausage-type container made of a flexible film was developed. Since it is a film, the waste is lightweight, and the volume is small because the film is folded during use. In the case of an extrusion gun used for extruding a sealing material or adhesive from a film pack using such a film, the film pack is stored in a cylinder body (or cylindrical adapter) and stored in the cylinder body. The sausage-type film pack is extruded and the rod is moved forward and pressed by a pressing plate to discharge the sealing material in the film pack from the nozzle. As a sausage type film pack type extrusion gun, for example, the applicant of the present application has already proposed the invention shown in Patent Document 2.

  In addition, a cartridge type extrusion gun can be used to extrude and discharge sealing material from a sausage type film pack. If there is a cartridge type extrusion gun, a sausage type film pack type extrusion gun can be purchased and used separately. The present applicant has already proposed the invention shown in Patent Document 3 as an extruding mechanism for a film pack that is not necessary.

  Furthermore, an extrusion gun having a lid that can be opened and closed at the tip (Patent Documents 4 and 5), a paste-like article dispenser using a cylinder that can be opened and closed by a hinge or the like (Patent Document 6), and the like have also been proposed. Yes.

  On the other hand, recently, a sealant-accommodating pouch that can be loaded into an extrusion gun without using a hard cartridge container is also disclosed in Patent Document 7. The sealant-containing pouch described in Patent Document 7 is a film pack type with a nozzle in which a nozzle is detachably provided on one side of the sausage type film pack as described above.

  Furthermore, recently, a soft cartridge container or the like in which the cartridge container is made of a soft material and the cartridge container can be compactly compressed has been proposed (Patent Document 8 and Patent Document 9).

  As described above, in recent years, there are a hard type and a soft type of container filled with a paste-like article. Therefore, an extrusion gun that can be easily used for both of them is desired.

  For example, in an extrusion gun of a type in which a sausage type film pack is loaded on a cylinder body (cylindrical adapter) as described in Patent Document 2 and Patent Document 3 described above, it is suitably used for a soft container filled with a paste-like article. However, an extra member such as a cylinder body is required, and there is a possibility that the operation becomes complicated.

  Moreover, even when using an extrusion gun of a type having a lid that can be opened and closed at the tip as described in Patent Document 4 and Patent Document 5, the work may be complicated.

  Furthermore, when using a dispenser provided with a lid that can be opened and closed with a hinge or the like as described in Patent Document 6, the operation is not complicated, but it is necessary to close the lid even when using the hard cartridge container described above. The situation of the cartridge container in use cannot be grasped. In addition, when the lid is opened, the center of gravity of the extrusion gun may be shifted due to the weight of the lid, and it may be difficult to hold the extrusion gun. This can be dangerous, especially when working at heights.
