Description

[0001] The invention relates to a drinking vessel cover including an air check valve for covering the drinking vessel and for preventing the dirt or saliva or contaminant from entering into the drinking vessel after use.

[0002] Typical drinking vessels or bottles comprise a cover attached onto the open mouth for covering the drinking vessel, and the cover may be disengaged from the drinking vessel for allowing the liquid or water or beverage contained in the drinking vessel to be drank by the user, and the cover may then be attached onto the open mouth of the drinking vessel again for covering the drinking vessel after use.

[0003] However, the typical drinking vessel covers include a complicated structure that may not be easily made and that may include a greatly increased manufacturing cost.

[0004] The invention is to provide a drinking vessel cover including an air check valve for covering the drinking vessel and for preventing the dirt or saliva or contaminant from entering into the drinking vessel after use.

[0005] The invention provides a drinking vessel cover as defined in claim 1. Advantageous embodiments are indicated in further claims.

FIGS. 1, 2 are perspective views of a drinking vessel cover;

FIGS. 3, 4 are partial exploded views of the drinking vessel cover, as seen from the upper portion and the bottom portion of the drinking vessel cover; and

FIGS. 5, 6, 7 are cross sectional views of the drinking vessel cover.

[0006] Referring to FIGS. 1-6, a drinking vessel comprises a vessel body or bottle 10 including a chamber 11 for containing liquid or beverage, an open mouth 12 communicating with the chamber 11 of the bottle 10 for allowing the liquid to be introduced into the chamber 11 of the bottle 10 and/or to be drank by the user, and arranged for attaching a cover device 3 to the mouth 12 and for covering or sealing the chamber 11 of the bottle 10.

[0007] The cover device 3 includes a cylindrical cover body or member 30 having an inner thread 31 for engaging with the mouth 12 and for detachably attaching to the mouth 12.

[0008] The cover member 30 includes a mouth or port 32 having a passage 33 communicating with the chamber 11 of the bottle 10.

[0009] The cover device 3 includes a plug 34 attached to the port 32 of the cover member 30 at the lower portion of the port 32 for covering the lower portion of the passage 33 of the port 32, and an orifice 35 formed in the plug 34 and communicating with the passage 33 of the port 32 and the chamber 11 of the bottle 10, and a tilted or inclined inner peripheral surface or valve seat 36 formed in the plug 34 for engaging with a valve piece or member 40 and for covering the passage 33 of the port 32 (FIGS. 2, and 5-6).

[0010] The cover device 3 further includes a spider or rib 37 attached to the port 32 of the cover member 30 at the upper portion of the port 32 and/or one or more pathways 38 formed in the upper portion of the port 32 and/or beside the rib 37 and communicating with the passage 33 of the port 32, for anchoring the valve member 40 within the passage 33 of the port 32 and for preventing the valve member 40 from being disengaged from the cover member 30, and a projection 39 extended from the rib 37 for engaging with the valve member 40 and for preventing the valve member 40 from blocking the pathways 38 of the port 32 or of the cover member 30 (FIG. 7).

[0011] The cover device 3 may include a cap 50 detachably attached to the port 32 and/or the cover member 30 for covering the passage 33 of the port 32 of the cover member 30. The cap 50 may be detachably attached to the port 32 of the cover member 30 with such as a force-fitted engagement for allowing the cap 50 to be detachably attached to the port 32 and/or the cover member 30.

[0012] In operation, when the cap 50 is disengaged from the cover member 30 (FIG. 7) and when the bottle 10 is disposed upside down, the user may drink the liquid from the port 32 of the cover member 30. At this moment, the projection 39 and/or the rib 37 of the cover member 30 may be engaged with the valve member 40 for preventing the valve member 40 from blocking the pathways 38 of the port 32 and/or of the cover member 30 and for allowing the liquid to be suitably drank by the user.

[0013] After use, the valve member 40 may be engaged with the valve seat 36 (FIGS. 2, 5-6) that is formed in the plug 34, due to gravity force, for blocking the passage 33 of the port 32 and for preventing the dirt or saliva or contaminant from entering into the chamber 11 of the bottle 10 after use.
