Definitions

  • the present disclosure relates to a container manufacturing method and a container manufacturing apparatus, which receive liquid, and more particularly, to a manufacturing method and a manufacturing apparatus of a container capable of storing and discharging a liquid, which can use all contents without remaining.
  • FIG. 1A is a diagram illustrating a device for storing liquid-phase contents with viscosity according to the related art.
  • Liquids such as shampoos and lotions are characterized by relatively large viscosity.
  • contents with large viscosity 20 have a property of sticking to the inner wall of the container due to the viscosity of the contents.
  • these products are generally sold by being contained in the hard container 10 having a small opening portion, as illustrated in FIG. 1A , because of beauty, convenience of use, etc. That is, most of them are sold by being contained in the hard container of the shape illustrated in FIG.
  • a method for discharging the contents generally uses a method for attaching a pump to a discharging portion 30, and sucking and discharging the contents to a discharging tube 31 by the pumping operation by the air pressure for convenience of use.
  • a method for attaching a pump to a discharging portion 30, and sucking and discharging the contents to a discharging tube 31 by the pumping operation by the air pressure for convenience of use there is no problem when the contents 20 are sufficient in a storing space of the container 10 and the contents can be discharged through the discharging tube 31, but there is a problem in that when the contents are not much remained in the container 10, the residual contents stick to the inner wall of the container, and are not well separated therefrom, such that it is difficult to discharge the residual contents, and this operates as a great obstacle to neatly use the contents such as shampoo and lotion.
  • FIG. 1B is a diagram illustrating the in-container state when the residual contents have been not much remained in the container for storing the liquid-phase contents with viscosity according to the related art.
  • the inventor of the present disclosure has recognized a problem in that it is difficult to discharge the residual contents by using a pump, etc. when the liquid contents stick to the inner wall of a container by the viscosity and the surface tension of the liquid contents and the residual contents are not much remained, in the case that the liquid, particularly, the liquid with high viscosity is stored in the hard container with a narrow opening portion, such that it is not practical. Nonetheless, the inventor has sufficiently recognized the voice of the relevant industry that the hard container should be used because the hard container makes the product look luxurious in appearance, and it is necessary to attach the pump, etc. to the discharging portion for convenience of use, etc.
  • the inventor of the present disclosure has devised a container and a device, which can put a pouch with the elasticity (an elastic pouch) into the hard container and store the liquid contents in the elastic pouch, thereby using the contents stored therein conveniently and completely even while using the hard container through a new and innovative method.
  • FIGS. 2A and 2B are diagrams illustrating a procedure of charging liquids into a hard container in a general manufacturing process of shampoo, lotion, etc.
  • the hard container in the case of a product sold by storing liquids such as shampoo or lotion in the hard container, the hard container is arranged in a line on a conveying apparatus 50 and conveyed to a contents charging equipment 51.
  • the contents charging equipment can have from one to a plurality of nozzles 60 according to its design.
  • the nozzle moves downwardly above the opening portion of each hard container to charge the contents therein through the nozzle 61.
  • the time of the nozzle movement for charging the contents and the charging amount per unit time of the nozzle are directly related to the production efficiency of the product, and therefore, generally, the nozzle vertically moves only by a minimum distance according to the designing method, or sprays the contents at that position without the movement so that the contents can be accurately stored in the hard container, and therefore, the nozzle and the opening portion of the hard container are mostly spaced apart from each other to perform an charging operation considering the production efficiency, etc.
  • the inventor of the present disclosure has also recognized a problem in that when the contents are charged into the elastic pouch through the corresponding method, an injection pressure of the contents injected through the opening portion of the hard container is not strong enough to overcome the elasticity of the elastic pouch due to the elasticity of the elastic pouch, and when the injection of the contents is not performed in a state where a contents injection nozzle has been in close contact with the hard container, it is not possible to contain the contents by the volume of the hard container by inflating the elastic pouch.

  • Still another object of the present disclosure is to provide a device, a container, and a method for manufacturing the same, which can inject the contents by using the conventional contents charging method even while providing the elastic pouch because the contents cannot be injected therein by the volume of the hard container by the elasticity of the elastic pouch in a state where the elastic pouch has not been expanded in advance when the charging nozzle uses a method for spraying or flowing the contents above the opening portion of the hard container like the conventional method in charging the contents in the hard container provided with the elastic pouch.
