Referring to fig. 1 to 3, the present invention provides a liquid container 1, which includes a container body 100 and a cover 200, wherein the container body 100 is used for containing liquid, an opening 110 is disposed above the container body 100, and the cover 200 is disposed at the opening 110 of the container body 100 for sealing the opening 110. In the present invention, the liquid may be a beverage for food, beer, or the like, a medical preparation, or a liquid for industrial use. In addition, the present invention does not limit the volume of the liquid container 100, and the liquid container 100 may be a beverage bottle with a small volume or a large storage tank used in industry. In one embodiment, the liquid container 1 is a beverage or beer packing bag, specifically, the container body 100 is a soft plastic bag, and the material of the cover 200 is a rigid plastic.

The cover 200 includes a sealing cover 210 and an opening cover 220, the sealing cover 210 is fixedly connected with the container body 100, specifically, the sealing cover 210 is disposed at the opening 110 of the container body 100, and when the liquid container 1 is not opened, the sealing cover 210 can close the opening 110; that is, when the liquid container 1 is not opened, the sealing cover 210 and the inner cavity of the container body 100 together enclose a sealed space. The opening cap 220 is rotatably coupled to the sealing cap 210, e.g., a consumer may twist the opening cap 220 to rotate the opening cap 220 relative to the sealing cap 210. In the present invention, the main body of the sealing cover 210 is the same as the conventional container cover, and includes a cylindrical outer side 211 and a top surface 212 for sealing one end of the cylindrical outer side, and the sealing cover 210 is screwed to the container body 100 through the outer side 211. Similarly, the opening cap 220 also includes a cylindrical outer side 221 and a top surface 222 closing one end of the cylindrical outer side 221.

A sealed cavity 260 is defined between the sealing cover 210 and the opening cover 220, a top penetrating mechanism 240 is arranged in the sealed cavity 260, and the top penetrating mechanism 240 can be partially connected to the sealing cover 210 and partially connected to the opening cover 220. When the opening cap 220 is rotated, the opening cap 220 may drive the piercing mechanism 240 to pierce the top surface of the sealing cap 210 to form a perforation on the top surface of the sealing cap 210. Further, a liquid outlet hose 230 is disposed on the opening cover 220, and when the top penetrating mechanism 240 penetrates the top surface 211 of the sealing cover 210, the liquid can flow out to the sealing cavity 260 through the through hole, and then flow out from the sealing cavity 260 through the liquid outlet hose 230. In one embodiment, the drain hose 230 is provided on the top surface of the open cover 220.

The liquid outlet process of the liquid container 1 provided by the present invention is exemplarily described as follows: rotating the opening cover 220 to drive the penetrating mechanism 240 to penetrate through the top surface of the sealing cover 210 to form a through hole; reversely rotating the opening cap 220 to the initial position; the liquid outlet hose 230 is conducted (the liquid outlet hose 230 can be in a closed state when not discharging liquid); the tilting vessel body 100, the liquid in the vessel body 100 flows out through the perforation and the liquid outlet hose 230; after pouring out the required amount of liquid, the liquid outlet hose 230 is closed. Utilize the utility model provides a liquid container 1, at whole play liquid in-process, outside air can not with enter into inside liquid container 1, can avoid the surplus liquid in the container to take place to contact with the outside air to can prolong the fresh-keeping term of surplus liquid in the liquid container 1.

Referring to fig. 2, in the present invention, the top-through mechanism 240 includes a first protrusion 241 connected to the opening cap 220 and a second protrusion 242 connected to the sealing cap 210. The first and

second protrusions

241 and 242 are configured in a structure in which: when the cap 220 is rotated to open, the first protrusion 241 interferes with the second protrusion 242, i.e., the first protrusion 241 may press the second protrusion 242, thereby pushing the top surface of the sealing cap 210 through. It should be noted that the "top-through" here may be a tearing of the top surface 212 of the sealing cover 210 by a shearing force transmitted by the second protrusion 242, a crushing by a pressing force transmitted by the second protrusion 242, or a combination of both.

Alternatively, the first protrusion 241 and the second protrusion 242 are both cylinders coaxial with the rotation axis of the opening cap 220, the surface of the first protrusion 241 facing the second protrusion 242 is a first inclined surface 241a, and the surface of the second protrusion 242 facing the first protrusion 241 is a second inclined surface 242a matched with the first inclined surface 241 a. When the opening cover 220 is in the initial state (i.e., when not rotating), the first inclined surface 241a and the second inclined surface 242a are in a parallel state, and when the opening cover 220 is rotated, the opening cover 220 drives the first protrusion 241 to rotate, and the first inclined surface 241a and the second inclined surface 242a are out of the parallel state, thereby generating interference. The first protrusion 241 applies a pressing force to the second protrusion 242, and the second protrusion 242 transmits the pressing force to the top surface 212 of the sealing cover 210. Continuing to rotate the opening cap 220, the pressing force exerted by the first protrusion 241 on the second protrusion 242 continues to increase until the pressing force pushes the top surface 212 of the sealing cap 210 through; the seal cap 210 may be opened by continued rotation to enlarge the crack in the top surface and increase the area of the perforation.

Alternatively, to save material and optimize the injection molding manufacturability of the cap body 200, the first protrusion 241 and the second protrusion 242 may be provided as hollow cylinders having equal diameters. It should be noted that, because the hollow cylinder itself has a certain thickness, the surface of the first protrusion 241 facing the second protrusion 242 (and the surface of the second protrusion 242 facing the first protrusion 241) may not be a plane in a strict sense, and at this time, the wall thickness of the hollow cylinder may be neglected when defining the first inclined surface 241a and the second inclined surface 242a, that is, the hollow cylinder is simplified into a shell without a thickness, the plane defined by the lower edge of the first protrusion 241 is the first inclined surface 241a, and the plane defined by the upper edge of the second protrusion 242 is the second inclined surface 242 a.

Alternatively, the second inclined surface 242a intersects with the top surface of the sealing cover 210, that is, the axial height of one side of the cylinder forming the second protrusion 242 is zero, and at this time, a front view of the cylinder forming the second protrusion 242 is triangular (as shown in fig. 1).

Optionally, the top surface of the sealing cover 210 is provided with a groove 213, where the groove 213 is located forming a weak portion of the top surface 212 of the sealing cover 210, so that the sealing cover 210 is more easily pushed through at the groove 213 when the cover 220 is rotated to open. In one embodiment, the groove 213 is an annular groove coaxial with the cylinder of the second protrusion 242 and located radially outward of the second protrusion 242. In another embodiment, the circular groove has a notch in the circumferential direction, and the notch is located opposite to the vertex of the second protrusion 242 along the radial direction of the circular groove. The provision of the gap in the annular groove allows the tear line to be a gap (i.e., the tear line is discontinuous) when the top surface 212 of the sealing cap 210 is pierced, so that the pierced portion of the top surface 212 of the sealing cap 210 remains on the sealing cap 210 rather than falling into the interior of the liquid container 1.

Referring to fig. 3, in the present invention, the sealing cover 210 is connected to the opening cover 220 by a snap-fit manner. For example, a cylindrical connecting wall 214 extending upward may be disposed on the top surface 212 of the sealing cap 210, a locking groove/rib may be disposed on the connecting wall 214, a rib/locking groove may be disposed at a position of the opening cap 220 corresponding to the locking groove/rib, and during assembly, the opening cap 220 may be pressed onto the sealing cap 210 to insert the rib into the locking groove corresponding to the locking groove, so as to achieve the snap-fit connection between the opening cap 220 and the sealing cap 210.

With continued reference to fig. 3, to optimize the assembly process, the cover 200 further includes a cover nozzle 270 fixedly connected to the container body 100, and the sealing cover 210 is fixedly connected to the container body 100 through the cover nozzle 270. The sealing cover 210 and the cover mouth 270 may be connected by a snap-fit connection, which refers to the connection between the sealing cover 210 and the opening cover 220 and is not described in detail.

To sum up, the above embodiments provided by the present invention are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
