Description

Technical Field

[0001] The utility model relates to a water cup, in particular to a cup with double chambers and expandable capacity. Background Art

[0002] Existing cups usually have a fixed internal volume and can only hold water according to the volume set during production. As consumers' demands for cup filling methods become more and more diverse, double-cavity water cups have gradually appeared on the market; a double-cavity thermos cup in the prior art (Chinese patent application number CN201620751079.6) has an inner liner in the cup body, leaving space between the outer wall of the inner liner, the inner wall of the cup body and the bottom cover to form an outer cavity, and the inner cavity of the inner liner and the outer cavity are combined to form a double cavity, but this design can only hold two different types or liquids of different temperatures, and the capacity of the water cup cannot be expanded; when going out or exercising, you often need to bring more water, and you need to buy a large-volume water cup or increase the number of cups to increase the amount of water you bring, which is inconvenient to carry and takes up space.

[0003] In order to solve the above technical problems, the applicant has designed a double-cavity expandable cup. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and provide a cup with double chambers and expandable capacity. The technical solution adopted by the utility model is as follows:

[0005] A double-cavity expandable cup comprises a cup body and a cup cover, wherein the cup body has a first cup mouth and a second cup mouth at both ends, the cup cover comprises a first cup cover and a second cup cover respectively sealingly matched with the first cup mouth and the second cup mouth, a flexible water bag is connected to either end of the cup body, the flexible water bag divides the inner cavity of the cup body into a first cavity with the first cup mouth as a water inlet and outlet and a second cavity with the second cup mouth as the water inlet and outlet; the flexible water bag can extend out of the first cup mouth or the second cup mouth in a stretched state, so that the volume of liquid contained by the flexible water bag and the cup body together is greater than the volume of the cup body.

[0006] The flexible water bag in the above structure firstly serves to separate the internal cavity of the cup body, so that two isolated first and second cavities are formed in one cup body, and the two cavities correspond to the first cup mouth and the second cup mouth, the first cup cover and the second cup cover respectively. The user can respectively fill and seal liquids of different types or temperatures in the two cavities for easy carrying or drinking; secondly, the flexible water bag can extend out of the first cup mouth or the second cup mouth in the stretched state, which means that the flexible water bag can play a role of capacity expansion. When a large amount of liquid needs to be held, the cup covers at both ends are opened, and liquid is injected into the first cavity from the first cup mouth. The flexible water bag continuously stretches and expands into the second cavity until it extends out of the second cup mouth. After filling, only the first cup mouth is closed. At this time, the volume of liquid contained in the water cup is greater than the volume of the inner cavity of the cup body.

[0007] Preferably, the open end of the flexible water bag is connected to the inner wall near the second cup mouth, and the flexible water bag can only extend out of the second cup mouth in the stretched state, but not beyond the first cup mouth; at this time, water is poured into the first cavity from the first cup mouth, and the flexible water bag stretches toward the outside of the second cup mouth, thereby playing a role of expanding the capacity; water is poured into the second cavity from the second cup mouth, and the flexible water bag stretches toward the direction of the first cup mouth without exceeding the first cup mouth. After filling with water, the second cup lid is tightened, the cup is inverted, and water can continue to be poured into the first cavity from the first cup mouth to hold two liquids at the same time.

[0008] Furthermore, it also includes a positioning cylinder that is detachably connected to the cup body; or, it includes a positioning cylinder that is sleeved outside the cup body and is slidable relative to the cup body.

[0009] Specifically, the two ends of the cup body are snap-connected or screw-connected (rotatably connected, such as threaded connection) with the positioning tube for positioning cooperation.

[0010] One implementation method may be: an I-shaped frame is protruding from the inner wall of the positioning tube, a first flange and a second flange are respectively provided on the outer walls of the first cup mouth and the second cup mouth of the cup body, and the first flange is provided with a first positioning groove and a first limiting narrow opening located on the first positioning groove, and the second flange is provided with a second positioning groove and a second limiting narrow opening located on the second positioning groove; the positioning tube has the function of sliding relative to the cup body, so that the I-shaped frame is embedded in the first positioning groove and screwed into the first limiting narrow opening, so that the cup body is just arranged in the storage position outside the cup body, and the positioning tube has the function of sliding relative to the cup body, so that the I-shaped frame is embedded in the second positioning groove and screwed into the second limiting narrow opening, so that the positioning tube is extended relative to the second cup mouth to an expansion position, at which time the positioning tube is extended relative to the second cup mouth and covered outside the flexible water bag.

[0011] Preferably, the extending length of the positioning tube relative to the second cup mouth in the expanded position is not greater than the length of the flexible water bag extending out of the second cup mouth in the stretched state, so that when the cup is expanded and used, the positioning tube supports and protects the portion of the flexible water bag extending out of the second cup mouth, thereby keeping the flexible water bag clean.

[0012] Finally, the first cup cover is screwed onto the inner wall of the cup body, and the second cup cover is screwed onto the outer wall of the positioning tube.

[0013] The beneficial effects of the utility model are as follows: the flexible water bag in the device first divides the internal volume of the cup body into a first volume and a second volume that are isolated from each other. The user can respectively contain and seal liquids of different types or temperatures in the two volumes for easy carrying or drinking; the flexible water bag can extend out of the first cup mouth or the second cup mouth in the stretched state to play a capacity expansion role. When a large amount of liquid needs to be contained, the cup covers at both ends are opened, and liquid is injected into the first volume from the first cup mouth. The flexible water bag continuously extends and expands into the second volume until it extends out of the second cup mouth. After the filling is completed, only the first cup mouth is closed. At this time, the volume of liquid contained in the water cup is greater than the volume of the inner cavity of the cup body. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] like Figure 1-2 As shown, a double-cavity expandable cup includes a cup body 1 and a cup cover, wherein the cup body 1 has a first cup mouth 11 and a second cup mouth 12 at both ends, and the cup cover includes a first cup cover 21 and a second cup cover 22 respectively sealingly matched with the first cup mouth 11 and the second cup mouth 12, and the end of the inner wall of the cup body 1 is connected to a flexible water bag 3, and the flexible water bag 3 divides the inner cavity of the cup body 1 into a first cavity 101 with the first cup mouth 11 as a water inlet and outlet and a second cavity 102 with the second cup mouth 12 as a water inlet and outlet; the flexible water bag 3 can extend out of the first cup mouth 11 or the second cup mouth 12 in a stretched state, so that the volume of liquid contained by the flexible water bag 3 and the cup body 1 is greater than the volume of the cup body 1.

[0029] The flexible water bag in the above structure firstly serves to separate the internal cavity of the cup body 1, so that two isolated first and second cavities are formed in one cup body, and the two cavities correspond to the first cup mouth 11 and the second cup mouth 12, the first cup cover 21 and the second cup cover 12, respectively. The user can respectively fill and seal liquids of different types or temperatures in the two cavities for easy carrying or drinking; secondly, the flexible water bag 3 can extend out of the first cup mouth 11 or the second cup mouth 12 in the stretched state, which means that the flexible water bag 3 can play a capacity expansion role. When a large amount of liquid needs to be filled, the cup covers at both ends are opened, and liquid is injected into the first cavity from the first cup mouth. The flexible water bag 3 continuously extends and expands into the second cavity 102 until it extends out of the second cup mouth. After filling, only the first cup mouth is closed. At this time, the volume of liquid contained in the water cup is greater than the volume of the inner cavity of the cup body.

[0030] In this embodiment, the open end of the flexible water bag 3 is connected to the inner wall near the second cup mouth 12, and the flexible water bag 3 can only extend out of the second cup mouth 12 in a fully stretched state, and does not exceed the first cup mouth 11; at this time, water is poured from the first cup mouth 11 into the first cavity 101, and the flexible water bag 3 stretches toward the outside of the second cup mouth 12, thereby playing a role of expanding the capacity; water is poured from the second cup mouth 12 into the second cavity 102, and the flexible water bag 3 stretches toward the direction of the first cup mouth 11 without exceeding the first cup mouth. After the water is filled, the second cup cover 22 is tightened, and the cup is inverted, and water can continue to be poured from the first cup mouth 11 into the first cavity 101 to simultaneously hold two liquids or liquids of different temperatures.

[0031] The first cup cover 21 is screwed to the inner wall of the cup body 1 , and the second cup cover 22 is screwed to the outer wall of the positioning tube 4 .

[0032] Example 2

[0033] like Figure 3-8 As shown, in embodiment 2, a positioning cylinder 4 is also included which is sleeved outside the cup body 1 and can slide relative to the cup body 1, and the two ends of the cup body 1 are snap-fitted and positioned with the positioning cylinder 4; specifically, an arc-shaped I-shaped frame 41 is protruded from the inner wall of the positioning cylinder 4, and the outer walls of the first cup mouth 11 and the second cup mouth 12 of the cup body 1 are respectively provided with a first flange 111 and a second flange 121, and the first flange 111 is provided with a first positioning groove 112 and a first limiting narrow opening 113 located on the first positioning groove 112, and the second flange 121 is provided with a second positioning groove 122 and a second limiting narrow opening 123 located on the second positioning groove 122; the positioning cylinder 4 has a storage position in which the I-frame 41 is embedded in the first positioning groove 112 and screwed into the first limiting narrow opening 113 so as to be just sleeved on the outer periphery of the cup body 1, and the positioning cylinder 4 has a sliding relative to the cup body 1 so that the I-frame 41 is embedded in the second positioning groove 122 and screwed into the second limiting narrow opening 123, so as to extend relative to the second cup mouth 12 of the cup body 1 and be connected to the expansion position near the second cup mouth 12.

[0034] The protruding length of the positioning tube 4 relative to the second cup mouth 12 is not greater than the length of the flexible water bag 3 protruding from the second cup mouth 12 in the stretched state, so that when the cup is used for expansion, the positioning tube 4 supports and protects the portion of the flexible water bag 3 protruding from the second cup mouth 12 to keep the flexible water bag 3 clean.

[0035] The first cup cover 21 is screwed to the inner wall of the cup body 1 , and the second cup cover 22 is screwed to the outer wall of the positioning tube 4 .

[0036] When the positioning tube 4 is in the storage position, the water cup can only be used as a double-cavity water cup; when the capacity needs to be expanded, the positioning tube 4 is rotated to make the upper end of the I-shaped frame 41 rotate out from the first limiting narrow opening 113, so that the I-shaped frame 41 is separated from the first positioning groove 112, and then the positioning tube 4 can slide relative to the cup body 1. When the I-shaped frame 41 slides and enters the second positioning groove 122, the positioning tube 4 is rotated to limit the lower end of the I-shaped frame 41 at the second limiting narrow opening 123. At this time, the positioning tube 4 extends out relative to the cup body 1 and is connected to the second cup mouth 12. The first cup cover 21 is opened to fill water into the first cavity 101, and the flexible water bag 3 gradually expands. The positioning tube 4 and the second cup cover 22 support

[0037] And protect the flexible water bag 3.

[0038] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
