Abstract

The present invention relates to the technical field of barreled water covers, and in particular to a barreled water cover that can be re-plugged and a top-through core for a water dispenser used in conjunction with the barreled water cover, comprising a cover body, an annular inner core that is recessed from the top of the cover body to the inside thereof, and an inner core plug that is engaged with the inner core; a hooking portion for engaging with the inner core plug is provided on the inner side of the bottom of the inner core, and a first annular groove engaged with the hooking portion is provided on the upper end of the outer side of the inner core plug; a second annular groove for engaging with the hooking portion is provided on the lower end of the outer side of the inner core plug when the water bucket is removed from the water dispenser. When the barreled water cover uses the top-through core of the water dispenser to push out the inner core plug, the pushed-out inner core plug will be fixed at the end of the top-through core, and at this time, the inner core plug will be separated from the annular inner core; when the water bucket is removed from the water dispenser again, the inner core plug on the top-through core will be re-fixed on the cover body, thereby preventing residual water in the bucket from leaking out when the water bucket is removed.

Description

Technical Field

[0001] The invention relates to the technical field of bottled water covers, in particular to a bottled water cover with a retractable plug and a top core of a water dispenser used in conjunction with the cover. Background Art

[0002] At present, the bottled water caps on the market basically adopt a one-time top-penetrating structure, among which the most important designs are the following two: the first is a built-in rubber plug, that is, there is a rubber plug assembled in the middle of the cap. When the bucket is placed in the water dispenser, the top-penetrating core of the water dispenser will push the rubber plug out and drop it into the drinking water; the second is a one-time top-penetrating film, that is, the current 4.5L barrel cap (such as Yilibao 4.5L bottled water), the film is injection molded with the cap body at one time. This design is an advanced design of the first built-in rubber plug. The advantage is that it can save the process of separately producing the rubber plug and assembling it into the cap body, simplifying the manufacturing process of bottled water.

[0003] Functionally, both designs have a flaw, that is, when the bucket is pulled out of the water dispenser, the remaining water will quickly leak out from the pierced position. Even if the water in the bucket seems to have been drunk, there will always be residual water leaking out when it is pulled out. In addition, the design of the built-in rubber plug has another flaw, that is, when the bucket is recycled, the rubber plug that was pushed into the bucket needs to be taken out, which increases the recycling process. Summary of the invention

[0004] One of the purposes of the present invention is to provide a reclosable barrel water cover to address the deficiencies in the prior art, wherein the reclosable barrel water cover can prevent residual water in the barrel from leaking out when the water is drawn out.

[0005] The second purpose of the present invention is to provide a top core of a water dispenser used in conjunction with a bottled water cover that can be retracted to address the deficiencies in the prior art.

[0006] To achieve one of the above objectives, the present invention is implemented through the following technical solutions.

[0007] Provided is a retractable barrel water cap, comprising a cap body, an annular inner core recessed from the top of the cap body toward the inside thereof, and an inner core plug engaged with the annular inner core;

[0008] The inner side of the bottom of the annular inner core is provided with a hooking portion for clamping with the inner core plug, and the upper end of the outer side of the inner core plug is provided with a first annular groove clamped with the hooking portion;

[0009] The lower end portion of the outer side of the inner core plug is provided with a second annular groove for engaging with the hook portion when the water bucket is pulled out of the water dispenser.

[0010] The top end portion of the outer side of the inner core plug above the first annular groove is inclined toward the inner side thereof.

[0011] The longitudinal section of the second annular groove is an arc-shaped surface.

[0012] The depth of the second annular groove is greater than the depth of the first annular groove.

[0013] The bottom of the inner core plug is configured as a concave bottom.

[0014] The bottom of the inner core plug is provided with an upward projection.

[0015] The convex block is configured as a convex block with an arc surface.

[0016] To achieve the second objective above, the present invention is implemented through the following technical solutions.

[0017] Provided is a top-penetrating core for a water dispenser used in conjunction with a re-pluggable barrel water cover, comprising a top-penetrating core head for inserting into and contacting the inner core plug, and a top-penetrating core arm connected to the top-penetrating core head; an annular groove is provided between the top-penetrating core head and the top-penetrating core arm.

[0018] The top-penetrating core head is configured as a top-penetrating core head with an arc-shaped surface.

[0019] Beneficial effects of the present invention:
