Abstract

The present invention provides an environment-friendly structure of a flexible tube, comprising a flexible tube, an inner bulk and a cover. After the flexible tube is fulfilled of a material, an inner bulk is disposed to the tail end and then the flexible tube is packaged. Therefore, when using the flexible tube, the flexible tube can provide a better pressing function, and the material in the flexible tube can be squeezed out completely without wasting any material for environmental protection.

Description

    FIELD OF THE INVENTION
  • The present invention relates to an environment-friendly structure of a flexible tube, especially to a flexible tube structure can be environmentally friendly, convenient, and waste free to be used, and suitable to various types of flexible tubes.
    • BACKGROUND OF THE INVENTION
  • Flexible tubes are used to contain skin care products, medicine, and cleaning products in the modern society. Considering the easiness and convenience of use and carrying, flexible tubes are usually the favorite containers. Usually, when manufacturing a flexible tube, a flexible tube, comprising an opening, a tail end and an inner hollow part, and a cover are made separately in die sinking at beginning. The tail end of the flexible tube is open. The material is fulfilled from the tail end and then the tail end is sealed by sealing equipment.
  • A flexible tube is made of a flexible material for being easy to be squeezed and folded. If the flexible tube is squeezed, the content can be squeezed out of the opening. But the material fulfilled in the flexible tube is thick paste. It is not only easy to be squeezed out but also easy to be adhesive to the inner wall of the flexible tube. Therefore, the content cannot be completely squeezed out. There is always a small part of the content left in the flexible tube. The user throws the flexible tube with a small part of the content away, or cuts the flexible open to scrape the content out of the flexible tube. But regarding to some medicine, skin care products, or cleaning products, if the content is not used or not contained in a clean container right away after the flexible tube is cut open, the content could be contaminated in the air and impair the quality of the content. It is not environmentally friendly, and may damage the user's life because the content is contaminated by the air.
    • SUMMARY OF THE INVENTION
  • The present invention relates to an environment-friendly structure of a flexible tube, comprising a flexible tube, an inner bulk and a cover. After the flexible tube is fulfilled of a material, an inner bulk is disposed to the tail end and then the flexible tube is packaged. It can ensure the content is not adhesive to the inner wall of the flexible tube in the process of squeezing the content, and is helpful to squeeze the content out of the flexible tube to reach the goal of environment protection, cost saving and easy-to-use.

  • FIG. 1 is the solid combination and explosion diagram of the present invention of an environment-friendly structure of a flexible tube.
  • FIG. 2 is the lateral view of the combination diagram of the present invention of an environment-friendly structure of a flexible tube.
  • FIG. 3 is the lateral view of the operation diagram of the present invention of an environment-friendly structure of a flexible tube.
  • FIG. 4 is the lateral view of the operation diagram of the present invention of an environment-friendly structure of a flexible tube.
    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The present invention relates to an environment-friendly structure of a flexible tube, referring to FIGS. 1-4. The structure comprises a flexible tube 1, comprising an inner hollow part 11 for containing a material, a tail end 12 at one end for fulfilling the material, a top end 13 at another end, an opening part 14 extended from the top end 13 for squeezing the material out. The opening part can be encompassed by the engaging part 31 of a cover 3.
  • The structure comprises an inner bulk 2, disposed in the inner hollow part 11 of the flexible tube 1. The bulk 2 comprises a inclined plane 21 at one end and a protrusion end 22 extends from the inclined planen 21. The shape of the protrusion end 22 is the same as the shape of the opening part 14 of the flexible tube 1. The size of the protrusion end 22 is less than the size of the opening part 14. In other words, the outer radius of the protrusion end 22 of the inner bulk 2 is smaller or equal to the inner radius of the opening 14 of the flexible tube 1; the inclined plane 21 of the inner bulk 2 and the top end 13 of the flexible tube 1 are in the same shape; the outer circumference of the inclined plane 21 of the inner bulk 2 is equal to an inner circumference of the inner hollow part 11 of the flexible tube 1. In other words, when the inner bulk 2 is pushed to the top end 13 of the flexible tube 1, the inclined plane 21 of the inner bulk 2 can closely touch the inner side of the top end 13 of the flexible tube 1. The protrusion end 22 of the inner bulk can be encompassed by the opening part 14 of the flexible tube 1. The inner circumference of the inclined plane 21 of the inner bulk 2 can closely lean against the inner wall of the inner hollow part 11 of the flexible tube 1 to scrape. The inner bulk cam be made in one-piece form or not in one-piece form, and made of rigid material or not rigid material.
  • The structure comprises a cover 3, in a recess shape. There is an engaging part 31 inside. The engaging part 31 can encompass the opening part 14 of the flexible tube 1 to seal the opening part 14 of the flexible tube 1.
  • Conventionally, a flexible tube 1 comprises an opening 14, a tail end 12 and an inner hollow 11 part, and top end 13 is made in one-piece form in die sinking at beginning. The tail end 12 of the flexible tube 1 is open. The material is fulfilled from the tail end 12. Regarding to the present invention, the content is fulfilled from the tail end 12 up to an appropriate quantity, and then an inner bulk 2 is disposed to the tail end 12. The protrusion end 22 of the inner bulk 2 faces the opening part 14 of the flexible tube 1. After the inner bulk 2 is disposed at the tail end 12, the tail end 12 of the flexible tube 1 is sealed by thermo-compression bonding or compression bonding. Then, the content fulfilling of the flexible tube 1 is completed.
  • After opening the cover 3, a user can squeeze any place of the flexible tube 1 to get the content, or push the inner bulk 2 from the tail end 12 toward the opening part 14 to get the content. When the content is almost completely removed out of the flexible tube 1, the inner bulk 2 can be pushed toward the opening part 14 and the outer circumference of the inclined plane 21 of the inner bulk 2 lean against the inner wall of the inner hollow part 11 of the flexible tube. When the inner bulk 2 is pushed to move toward the opening part 14, the outer circumference of the inclined plane 21 of the inner bulk 2 scrapes alone the inner wall of the hollow part 11 of the flexible tube 1. It can push the content adhesive to the inner wall of the hollow part 11 toward the opening part 14. Eventually, the inclined plane 21 of the inner bulk 2 will touch the inner surface of the top end 13 of the flexible tube, and the protrusion end 22 of the inner bulk 2 will engage with the inner part of the opening part 14 of the flexible tube 1. In other words, all of the content will be squeezed out completely. The user need not to cut the flexible tube 1 open and can squeeze the content out of the flexible tube 1 completely. It is convenient, safe, thrifty, and environmentally protective.
