Abstract
A safety device of a cap sealing a liner of a thermos bottle comprises a rod of a pushing member passing through a through hole of a lock assembly that is for being screws with the opening of the liner wherein after the rod is pierced into an accommodating space of the lock assembly and combined with components therein, the rod juts out a fastening member deposited in the depression of the cap to be combined with a moving member, whereby when there is a pressurized steam in the liner, the steam lifts the pushing member so that the rod pushes upward to disengage the moving member from a recess of the fastening member and in turn sit the moving member in the corresponding gaps of the upper decorating plate so that this point, even if the cap is rotated, the cap does not drive the lock assembly to rotate.
Description
- 1. Technical Field
- The present invention relates to a safety device of a cap sealing a liner of a thermos bottle. More particularly, the present invention relates to a safety device for preventing a cap sealing a liner of a thermos bottle from being incautiously opened when a high-temperature steam is stored in the thermos bottle so as to prevent scald-accidents.
- 2. Description of Related Art
- In a container storing a high-temperature steam therein, for protecting a user from scald-accidents that may happen when the user incautiously opens the container with his/her hands, a safety device is typically equipped at an opening of the container. For example, U.S. Pat. No. 7,237,409, which is titled as “Steam Cleaner with Safety Device” and proposed by the same inventor as of the present invention, provides a safety device mounted on a cap of a steam cleaner. Therein, a
lock assembly 5 is settled at a bottom of arotary cap 31. Ahollow cylinder 53 passing through acylindrical base 51 has a top annular flange 531 extending upward. Two opposite slots 532 are such formed at the annular flange 531 that two opposite tabs 522 provided on an edge of a hole 521 of ahollow driving disk 52 abutting upon thecylindrical base 51 can stably engage therewith. Furthermore, anactuation assembly 4 downward assembled to thelock assembly 5 has a cylindrical seat 41 for being screwed with a shroud 42. Between the cylindrical seat 41 and the shroud 42, a flexible actuating member 44 is high-heat resistant and has a central through hole for allowing a top push rod 451 of a pushing member 45 to pass therethrough and penetrate a hole 421 formed at the shroud 42 so that an annular groove 453 provided on a base 452 of the pushing member 45 can be matingly engaged with a ridge 442 formed downward from the actuating member 44. - The assembled cap assembly 3 is fastened to a top of a
steam chamber 2 in a screw means. When a high-heat steam 6 is generated in thesteam chamber 2, thesteam 6 surges upward through holes of thehollow cylinder 53 and avalve 54 in thelock assembly 5 so that thesteam 6 lifts the pushing member 45 settled between the cylindrical seat 41 and the shroud 42 until the actuating member 44 tightly compresses against the shroud 42. Meanwhile, the push rod 451 raised from the pushing member 45 also lifts acylindrical clutch 32 so that a plurality oflegs 321 extending downward from thecylindrical clutch 32 are disengaged from thedriving disk 52 of thelock assembly 5, thereby resulting in disengagement between thecap 31 and thelock assembly 5. At this point, even if a user rotates thecap 31 by hands, thecap 31 does not drive thelock assembly 5 to rotate and therefore thelock assembly 5 in the cap assembly 3 is free from being opened. Consequently, the cap 3 is prevented from being incautiously opened so that the user is protected from being scalded by the high-heat steam 6 in thesteam chamber 2. - When the
steam 6 inside thesteam chamber 2 is almost released out, since the steam pressure is dissipated, afirst spring 33 between thecap 31 and thecylindrical clutch 32 pushes theactuation assembly 4 downward in strength of a bounce thereof, and in turn engages thelegs 321 at the bottom of thecylindrical clutch 32 with thedriving disk 52 of thelock assembly 5 again, thereby resulting in engagement between thecap 31 and thelock assembly 5 so that when a user rotates thecap 31 by hands, the cap assembly 3 is opened. - The present invention therefore applies the principle of the above-mentioned safety device that prevents a cap of a container containing a high-temperature steam from being incautiously opened so as to provide against scald-accidents to a cap sealing a liner of a thermos bottle as a safety device in order to fully prevent the cap sealing the liner of the thermos from being opened incautiously due to carelessness and therefore prevent scald-accidents.
- A first objective of the present invention is to provide a safety device which is characterized in a rod of a pushing member passing through a through hole formed at a center of a lock assembly that is for being screws with the opening of the liner; the rod being retained in an accommodating space of the lock assembly with a first blocker and a second blocker, which are further positioned with respect to the rod by a c-shaped ring; the lock assembly being covered by the cap; a fastening member being settled in a depression of the cap; a spring being deposited between the fastening member and the accommodating space of the lock assembly; a recess formed at an upper end of the fastening member fittingly receiving a moving member having a plurality of protrusions formed at a periphery thereof; a hole formed at a center of the fastening member allowing the rod to be pierced therethrough so that the rod can be combined with the moving member positioned thereon; and a plurality of the cavities at an upper periphery of the cap being engaged with a plurality of hooks extended downward from an upper decorating plate, whereby when there is a pressurized steam in the liner assembled with the safety device, the steam lifts the pushing member having the rod so that the rod pushes upward to lift the moving member so as to disengage the moving member from the recess of the fastening member and in turn sit the moving member in the corresponding gaps of the upper decorating plate and at this point, even if the cap is rotated, the cap does not drive the lock assembly to rotate, thereby scalded-accidents caused by a user's incautiously opening the cap sealing the liner being efficiently prevented.
- A second objective of the present invention is to provide the aforementioned safety device wherein the fastening member settled in the depression is combined with the lock assembly as a whole by a plurality of screws.
- A third objective of the present invention is to provide the aforementioned safety device wherein a plurality of spacers are extended downward from the upper decorating plate that is engaged with the cavities at the upper periphery of the cap so that the plural spacers define gaps for receiving the moving member when the moving member is lifted.

lock assembly 1 has anaccommodating space 11 formed at a center thereof for allowing the first andsecond blockers FIG. 5 ). A throughhole 12 is formed in thelock assembly 1 below theaccommodating space 11. A limitingmember 13 having a plurality of throughholes 131 can be received in thelock assembly 1 and around theaccommodating space 11. Anannular plane 14 is formed at a top periphery of thelock assembly 1 and apush segment 15 having a plurality ofcavities 151 is formed at a center of theannular plane 14. - The pushing
member 2 is a component combined with one end of arod 21 and can be lifted by a steam (as shown inFIG. 5 ). The pushingmember 2 comprises a contactingportion 22 serving to engage with a lower end of therod 21, and a coveringportion 23 serving to retain therod 21. Therein, the contactingportion 22 and the coveringportion 23 are preferably made of a high-heat resistant and slightly flexible material. The coveringportion 23 has atube 231. When thetube 231 is put around therod 21, a protrudingannular edge 232 below thetube 231 can be fittingly combined with agroove 221 of the contactingportion 22 as a whole. - The
first blocker 31 has aprotrusion 311 extended downward therefrom and agroove 312 formed at an upper end thereof. Thesecond blocker 32 also has aprotrusion 321 extended downward therefrom and anotherprotrusion 322 for positioning thespring 4. Throughholes second blockers rod 21 pass therethrough (as shown inFIG. 5 ). In addition, the first andsecond blockers - The
cap 5 has adepression 51 formed at a center thereof for allowing the fasteningmember 6 to be settled therein. A throughhole 52 is formed in thedepression 51 for receiving thepush segment 15 of thelock assembly 1. A plurality ofcavities 53 are formed at an upper periphery of thecap 5 so that a plurality ofhooks 541 extended downward from a lower periphery of anupper decorating plate 54 can engage therewith. Furthermore, a plurality ofspacers 542 are also extended downward from theupper decorating plate 54 to definegaps 543 with intervals therebetween. - The fastening
member 6 has arecess 61 formed at an upper end thereof and shaped according to a peripheral contour of the movingmember 7. Ahole 62 is formed at a center of therecess 61 for allowing therod 21 passing therethrough. Anannular groove 63 is formed at a bottom of thefastening member 6 for receiving thepush segment 15 of thelock assembly 1 and an end of the spring 4 (as shown inFIG. 5 ). Besides, a plurality of threadedholes 64 are provided at an upper surface of thefastening member 6. - The moving
member 7 has a plurality ofprotrusions 71 formed at a periphery thereof. - To assemble the
lock assembly 1, the pushingmember 2, the first blocker and thesecond blocker spring 4, thecap 5, thefastening member 6 and the movingmember 7, as shown inFIGS. 3 and 5 , therod 21 of the pushingmember 2 is pierced through the throughhole 12 of thelock assembly 1 that can be screwed with the opening of the liner. Therod 21 is therefore retained in theaccommodating space 11 of thelock assembly 1 with the first thesecond blockers rod 21 by a c-shaped ring 33. Theannular plane 14 at the top periphery of thelock assembly 1 is covered by thecap 5. Then the fasteningmember 6 is settled in thedepression 51 of thecap 5. Thespring 4 is deposited between thefastening member 6 and theaccommodating space 11 of thelock assembly 1. Thus, the fasteningmember 6 can be positioned on thepush segment 15 of thelock assembly 1 by a plurality ofscrews 65. Therecess 61 formed at the upper end of thefastening member 6 fittingly receives the movingmember 7 having theplural protrusions 71 formed at the periphery thereof. Thehole 62 formed at the center of thefastening member 6 allows therod 21 to be pierced therethrough so that therod 21 can be combined with the movingmember 7 positioned thereon. Thecavities 53 at the upper periphery of thecap 5 are designed to be engaged with the plural hooks 541 extended downward from theupper decorating plate 54. After the aforementioned components are such assembled as shown inFIGS. 4 and 5 , thesafety device 8 is accomplished. - Referring to
FIGS. 1 and 6 , when there is apressurized steam 9 in theliner 10 assembled with thesafety device 8, thesteam 9 lifts the pushingmember 2 having therod 21. As a result, therod 21 pushes upward to lift the movingmember 7 so that the movingmember 7 is disengaged from therecess 61 of thefastening member 6 and in turn sit in the correspondinggaps 543 of theupper decorating plate 54. At this point, even if a user rotates thecap 5 by hands, thecap 5 does not drive thelock assembly 1 to rotate, thereby scalded-accidents caused by the user's incautiously opening thecap 5 sealing theliner 10 being efficiently prevented. - On the other hand, when there is no steam in the
liner 10, as shown inFIG. 5 , the movingmember 7 combined at the end of therod 21 gravitatively falls from thegaps 543 of theupper decorating plate 54 and gets engaged with therecess 61 of thefastening member 6 again. At this point, a user can open thecap 5 on theliner 10 by rotating it, as shown inFIG. 2 .
