Description

  The present invention relates to a thermos technical field, and more particularly, to a thermos having a multiple sealed heat retaining structure and an easily removable glass inner bottle.

  The thermos currently marketed mainly includes a body and a bottle lid, and forms a sealed heat-retaining space by a screw connection between the body and the bottle lid. However, there are variations in the quality of conventional thermos bottles, and there are many cases where the effect of heat insulation cannot be achieved, and there are also problems such as poor heat-tightness due to heat loss in the body too fast. Next, in order to increase the heat retention performance of the conventional thermos, the inner and outer walls of the body were connected by welding, but once the inner wall was damaged during actual use, the thermos lost its heat retention. Moreover, it is impossible to continue using the thermos by replacing the inner wall. Therefore, there is a need for a more reliable thermos bottle with a glass bottle that can be replaced or removed, with better sealing and better heat retention.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a thermos bottle having a multiple sealed heat retaining structure and an easily removable glass inner bottle in order to solve the shortage of the prior art.

  In order to achieve the above object, the present invention provides a thermos having a multiple sealed heat retaining structure and an easily removable glass inner bottle. The thermos bottle includes a bottle lid, a fixed lid, a water shielding sheet, a seal ring, a glass inner bottle, and a body. A body opening outer thread and a body opening inner thread are respectively formed on the outer surface and the inner surface of the opening of the body. The body opening outer screw thread and the body opening inner screw screw respectively engage with the bottle cap screw thread formed on the inner surface of the bottle lid and the glass inner bottle screw thread formed on the outer surface of the glass inner bottle. The seal ring covers the outer surface of the glass inner bottle. When the body is engaged and connected to the glass inner bottle, the lower surface of the seal ring is in contact with the opening edge of the body, and the fixed lid is engaged and connected to the inner ceiling portion of the bottle lid, A sheet is placed outside the fixed lid. When the body is engaged and connected to the bottle lid, the water shielding sheet engages and seals with the opening of the glass inner bottle.

  Furthermore, a fixed boss is formed on the inner ceiling portion of the bottle lid, and the fixed boss engages with and is connected to a fixed locking groove opened in the fixed lid.

  Furthermore, a plurality of ribs are formed on the outer surface of the water shielding sheet.

  Furthermore, an engaging portion that engages with the top of the fixed lid is formed on the inner surface of the water shielding sheet.

  Furthermore, a vacuum hollow pinching layer is provided in the body.

  The present invention has the following advantageous effects by taking the above solution. A thermos sealing structure is made up of a bottle lid, a fixed lid, a water shielding sheet, a seal ring, a glass inner bottle and a body. The glass inner bottle and the body are connected and fixed by screw threads, and the seal ring is pressed up and down to achieve easy replacement of the glass inner bottle and a sealing effect between the glass inner bottle and the body. The opening of the glass inner bottle engages with the water-impervious sheet, thereby achieving water leakage prevention and sealing effects. At the same time, by the engagement connection between the three parts of the bottle lid, the fixed lid and the water shielding sheet, and the vacuum hollow sandwich layer of the body, heat exchange between the heat in the glass inner bottle and the outside air is shut off, Further increase the thermal insulation performance of the thermos. And since the replacement and removal of the inner glass bottle are easy, the thermos bottle lasts longer, and it becomes possible to remove the inner glass bottle and use the body directly.

  The present invention will be further described according to specific embodiments.

  As shown in FIGS. 1 to 11, in this embodiment, a thermos bottle having a multiple sealed heat retaining structure and an easily removable glass inner bottle includes a bottle lid 2, a fixed lid 5, a water-impervious sheet 6, a seal ring 4, and a glass interior. A bottle 3 and a body 1 are provided. A body opening outer thread 11 and a body opening inner thread 12 are respectively formed on the outer surface and the inner surface of the opening of the body 1. The body opening outer thread 11 and the body opening inner thread 12 are respectively connected to the bottle cap screw thread 22 formed on the inner surface of the bottle cap 2 and the glass inner bottle screw thread 31 formed on the outer surface of the glass inner bottle 3. Match. The seal ring 4 is covered on the outer surface of the glass inner bottle 3. When the body 1 is engaged and connected to the glass inner bottle 3, the lower surface of the seal ring 4 comes into contact with the opening edge of the body 1, and the body 1 and the inner glass bottle 3 press the seal ring 4 up and down. To achieve a sealing effect. A fixed boss 21 is formed on the inner ceiling of the bottle lid 2. A fixed locking groove 51 that engages with the fixed boss 21 is opened in the fixed lid 5. The water shielding sheet 6 is covered outside the fixed lid 5. An engagement portion 62 that engages with the top of the fixed lid 5 is formed on the inner surface of the water shielding sheet 6, and the water shielding sheet 6 can be connected to the fixed lid 5 more firmly by installing the engagement portion 62. Moreover, the fall of the sealing performance by fall of the water-impervious sheet 6 is avoided. A plurality of ribs 61 are formed on the outer surface of the water shielding sheet 6. After the body 1 is engaged with and connected to the bottle lid 2, the water shielding sheet 6 is engaged with the opening inner surface of the glass inner bottle 3. The water shielding sheet 6 prevents water leakage and achieves a sealing effect together with the glass inner bottle 3. By providing the plurality of ribs 61 that come into contact with the inner surface of the glass inner bottle 3, the sealing performance between the water shielding sheet 6 and the glass inner bottle 3 is further enhanced. A hollow pinching layer is provided in the body 1. When the glass inner bottle 3 is placed in the body 1, the amount of heat transferred from the liquid inside the glass inner bottle 3 to the outside of the body 1 through the body 1 is reduced and heat loss is reduced. Reduced. By the configuration and engagement use of the above parts, the thermos has a multiple sealed heat insulation structure, and the heat insulation performance, reliability, and sealability of the thermos are further improved. Next, since the inner glass bottle 3 is easy to attach and detach, the thermos can replace or remove the inner glass bottle 3, and the thermos bottle will last longer. At the same time, when the glass inner bottle 3 is broken and not replaced or when it is not necessary to use the inner glass bottle 3 according to its own demand, the inner glass 3 is removed and the body 1 is used directly. Can do.
