Definitions

  • the present invention relates to a cap structure for a fragile bottle which caps an opening of the fragile bottle tightly and prevents toxic substances (e.g. plasticizers) from dissolving in the bottle contents, thereby increasing food safety.
  • toxic substances e.g. plasticizers
  • the bottle bodies and caps of plastic containers for containing water, beverages, or food in the market are made of plastic. Since the plasticizer contained in the plastic container may be dissolved in the contents of the container, it may be eaten by people and cause health damage.
  • fragile bottles e.g. glass and ceramics are also used to hold water, drinks or food.
  • the bottle caps of fragile bottles are also made of plastic materials, so the plasticizer may be dissolved in the contents when the contents contact the plastic bottle cap.
  • some fragile bottles have metal bottle caps covered on their opening, but a plastic inner film disposed on the inner surface of metal bottle cap will still contact the contents, so the problem of the plasticizer dissolving into the contents cannot be completely avoided.
  • Fragile bottles especially glass and ceramics are usually formed by sintering, so the upper edge of the bottle opening usually lacks flatness. When the metal bottle cap is covered on the bottle opening, there will be a gap between the metal bottle cap and the upper edge of the bottle opening. As a result, the liquid content leaks out easily and are easily deteriorated due to contamination by microorganisms such as bacteria.
  • the object of the present invention is to provide a cap structure for a fragile bottle which caps an opening of the fragile bottle tightly and prevents toxic substances (e.g. plasticizers) from dissolving in the bottle contents, thereby increasing food safety.
  • toxic substances e.g. plasticizers
  • the cap structure for a fragile bottle of the present invention comprises a main body having an open end, a close end, an inner space and a connecting part formed at the open end; an elastic pad disposed at an upper end of the inner space of the main body; and a stainless steel lining disposed in the inner space of the main body to move between the elastic pad and the connecting part. Accordingly, when the cap structure for a fragile bottle of the present invention is covered on an opening of a fragile bottle, a covering angle of the stainless steel lining that can move in the inner space can be changed according to an uneven upper edge of the opening so as to cap the opening tightly, avoid leakage of bottle contents, and prevent toxic substances (e.g. plasticizers) from dissolving in the bottle contents, thereby increasing food safety.
  • toxic substances e.g. plasticizers
  • FIG. 1 is an explosion diagram showing a cap structure for a fragile bottle according to the present invention
  • FIG. 2 is a stereogram showing a cap structure for a fragile bottle according to the present invention
  • FIG. 3 is a cross-sectional view showing a cap structure for a fragile bottle according to the present invention.
  • FIG. 4 is a cross-sectional view showing a cap structure for a fragile bottle in use according to the present invention.
  • FIG. 5 is a cross-sectional view showing a sealing recess of a stainless steel lining covered on an opening of a fragile bottle according to the present invention.
  • a cap structure for a fragile bottle As showed in FIG. 1 to FIG. 3 , a cap structure for a fragile bottle according to the present invention is disclosed herein. It comprises a main body ( 1 ) made of metal material, e.g. stainless steel, an elastic pad ( 2 ) and a stainless steel lining ( 3 ).
  • the main body ( 1 ) has an open end ( 11 ), a close end ( 12 ), an inner space ( 13 ) defined by the open end ( 11 ), an inner wall thereof and the close end ( 12 ), and a connecting part ( 14 ) formed at the open end ( 11 ).
  • the connecting part ( 14 ) is a thread section formed on the inner wall of the main body ( 1 ).
  • the main body ( 1 ) is further provided with a plurality of anti-slip protrusions ( 15 ) at an outer periphery of the close end ( 12 ) thereof.
  • the elastic pad ( 2 ) is fixedly disposed at an upper end of the inner space ( 13 ) of the main body ( 1 ).
  • the stainless steel lining ( 3 ) is disposed in the inner space ( 13 ) of the main body ( 1 ) and limited to the inner space ( 13 ) by the connecting part ( 14 ), so that it can move between the elastic pad ( 2 ) and the connecting part ( 14 ).
  • the stainless steel lining ( 3 ) is further provided with a sealing recess ( 31 ) facing the open end ( 11 ) of the main body ( 1 ), and a periphery of the sealing recess ( 31 ) is formed with a bevel edge ( 32 ).
  • the connecting part ( 14 ) (preferably a thread section) provided on the inner wall of the inner space ( 13 ) of the main body ( 1 ) can be screwed with an external thread section ( 42 ) disposed on an outer wall of the opening ( 41 ) of the fragile bottle ( 4 ) by applying a force on the main body ( 1 ) to rotation.
  • the opening ( 41 ) of the fragile bottle ( 4 ) contacts the sealing recess ( 31 ) of the stainless steel lining ( 3 ) and further pushes the stainless steel lining ( 3 ) to move towards the elastic pad ( 2 ) as the fragile bottle ( 4 ) continues to screw into the inner space ( 13 ) until the stainless steel lining ( 3 ) is completely in contact with the elastic pad ( 2 ) and positioned.
  • the bevel edge ( 32 ) formed on the periphery of the sealing recess ( 31 ) allows the stainless steel lining ( 3 ) to tightly cover and seal the opening ( 41 ) of the fragile bottle ( 4 ). Since the stainless steel lining ( 3 ) can move in the inner space ( 13 ), a covering angle of the stainless steel lining ( 3 ) can be adjusted according to an uneven upper edge of the opening ( 41 ) of the fragile bottle ( 4 ). Additionally, the elastic pad ( 2 ) provides support for the stainless steel lining ( 3 ) to ensure that the stainless steel lining ( 3 ) firmly covers and seals the opening ( 41 ) of the fragile bottle ( 4 ). In this way, the present invention avoids leakage of liquid contents contained in the fragile bottle ( 4 ) and avoids contamination by microorganisms such as bacteria due to the gap between the main body ( 1 ) and the upper edge of the opening ( 41 ).
  • the stainless steel lining ( 3 ) prevents toxic substances such as plasticizers from dissolving in the liquid contents, so it can ensure the food safety when consumers eat or drink the liquid contents of the fragile bottle ( 4 ), thereby avoiding harm to health.
  • the main body ( 1 ) of the present invention is formed with the plurality of anti-slip protrusions ( 15 ) at the outer periphery of the close end ( 12 ) to increase the force of friction. Therefore, consumers can easily open the main body ( 1 ) of the present invention from the opening ( 41 ) of the fragile bottle ( 4 ). Furthermore, since the stainless steel lining ( 3 ) can move in the inner space ( 13 ) of the main body ( 1 ), the inner space ( 13 ) can be easily cleaned to reduce the residue of dirt, which also improves the hygiene and safety of use.
  • the cap structure of the present invention has effects of good sealing, non-toxicity, easy cleaning and the like, which increase the user's willingness to reuse the cap structure without discarding the cap structure after one use, so it also achieves environmental benefit of saving material resource and avoids environmental pollution.
  • the cap structure for a fragile bottle according to the present invention has the advantages as following:
  • the stainless steel lining of the present invention can move in the inner space, so the covering angle of the stainless steel lining can be adjusted according to the uneven upper edge of the opening of the fragile bottle. Additionally, the elastic pad provides support for the stainless steel lining to ensure that the stainless steel lining firmly covers and seals the opening of the fragile bottle.
  • the bevel edge formed on the periphery of the sealing recess allows the stainless steel lining to tightly cover and seal the opening of the fragile bottle, so the prevent invention achieves the effect of completely sealing the upper edge of the bottle opening, thereby effectively preventing leakage and deterioration of liquid contents.
  • the present invention seals the bottle opening by contact with the stainless steel lining which prevents toxic substances such as plasticizers from dissolving in the liquid contents, so it can ensure the food safety when consumers eat or drink the liquid contents of the fragile bottle.
  • the stainless steel lining of the present invention can moved in the inner space of the main body, so the inner space can be easily cleaned to reduce the residue of dirt, which also improves the hygiene and safety of use.
