Benefits of technology

[0005] The present invention relates to a vacuum bottle that includes a bottle and a cap mounted on a top opening of the bottle, and the cap has pipes and vacuuming members connected thereto. A through hole and a release hole are respectively defined through the cap and a release tub is engaged with the release hole. A sleeve and a bellow member are received in the through hole and the sleeve is moved relative to the through hole by deformation of the bellow member due to pressure change. A valve assembly is located between the pipes and the bottle so as to prevent air from entering the bottle.

Problems solved by technology

It is noted that the cap 61 is cooperated with the cover 70 and the two parts requires two different molds to manufacture and this increase the cost of manufacture.
Besides, the release valve 60 cannot perfectly seal the bottle 60.

Embodiment Construction

[0016] Referring to FIGS. 1, 2, 3A and 3B, the vacuum bottle of the present invention comprises a bottle 10 and a cap 20 mounted on a top opening of the bottle 10. The cap 20 has two pipes 23 and vacuuming members 24 connected thereto. A through hole 21 and a release hole 22 are respectively defined through the cap 20 and a release tub 50 is engaged with the release hole 22. A sleeve 36 and a bellow member 37 are received in the through hole 21 and the sleeve 36 can be moved relative to the through hole 21 by deformation of the bellow member 37 due to pressure change so that the users are acknowledged of the vacuum status in the interior of the bottle 10 by the position of the sleeve 36. The release tab 50 has a date ring 51 co-axially connected thereto which shows the date that the food or the like is put in the bottle 10.

[0017] A connection member 30 is threadedly connected with the through hole 21 and includes an upper threaded portion 32 and a lower threaded portion 33. A flang...

Abstract

A vacuum bottle includes a bottle with a cap mounted on a top opening of the bottle, the cap having pipes and vacuuming members connected thereto so as to vacuum the interior of the bottle. A through hole and a release hole are respectively defined through the cap. A sleeve, a connection member and a bellow member are respectively received in the through hole. When vacuuming the interior of the bottle, the bellow member is compressed to lift the sleeve out from the through hole. When the vacuum status is released, the bellow member is released and the sleeve is merged in the through hole. By the movement of the sleeve, users are acknowledged the status in the bottle. A valve assembly is connected to the pipes in the cap so as to prevent air from entering into the bottle.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a vacuum bottle having a dual seal assembly to ensure the vacuum status in the bottle and an indicator is used to easily identify the status in the bottle. BACKGROUND OF THE INVENTION [0002] A conventional vacuum bottle is disclosed in FIGS. 7A and 7B, and generally includes a bottle 60, a cap 61 and a cover 70. The cap 61 has a tube 62 with a spring 621 and a bellow member 622 mounted thereto, a top cap 623 seals a top opening of the tube 62. when vacuuming the interior of the bottle 60 by using the vacuuming member 64 via the pipes 63, the bellow member 622 is compressed by the lower pressure, and expand to its original status when the vacuum status disappears and protrudes from the hole 71 of the cover 70. By this way, the users identify the status of the bottle 60. Another hole 72 is defined in the cover 70 so that the user may press the release valve 66 in the release hole 65 of the cap 61 to allow air to enter into...
