Description

Tumbler {Tumbler}

The present invention relates to a tumbler, and more specifically, to a tumbler that can conveniently carry and drink two different types of beverages.

A tumbler is a cup that has no handle and is slightly elongated. It is called a tumbler because it rolls (tumbles) without a handle if it falls over.

Tumblers have been gaining popularity in many countries around the world since the 2010s, when tumblers with lids were distributed through cafes. The standard tumblers sold commercially have a long and thick body like a conventional tumbler, but they have a lid added like a water bottle. This lid has a small additional lid attached to it, so that you can drink water without opening the entire lid. The additional lid is usually a slide or snap type, and in rare cases, there is a type that opens by turning like a beverage bottle. Depending on the product, a mug handle or straw may be added.

Since 2018, as most countries around the world began to regulate disposable products to solve environmental problems caused by disposable products, multinational franchises have been preferentially using tumblers as a replacement for disposable coffee cups. Accordingly, existing camping equipment/sealed container manufacturers have been competing to produce tumblers, and as a result, tumblers have become popular.

As tumblers become more popular, products previously sold under the names of thermos flasks, water bottles, bottles, flasks, and thermos are now being sold simply as tumblers.

As tumblers became more popular, tumblers with various functions were developed to meet various needs.

As a specific example, Korean Patent Publication No. 10-2010-0098161 and Korean Patent Registration No. 10-2119174 disclose a tumbler with a built-in straw for easy drinking.

However, these tumblers have a limitation in that they only form a single storage space and can only hold one beverage.

Tumblers that only accommodate one type of beverage, such as iced coffee and hot coffee, juice and milk, or coffee and tea, have the disadvantage of being difficult to carry around as users who prefer two types of beverages, such as iced coffee and hot coffee, juice and milk, or coffee and tea, must carry around two tumblers.

Accordingly, as disclosed in Korean Patent Publication No. 10-2018-0001101, 'Dual Tumbler', a tumbler that forms a double internal insulation space by forming a double internal insulation space so that two types of beverages can be stored has been disclosed.

However, since such a tumbler simply divides a single storage space, there is a problem that when drinking a beverage, the beverage is discharged through the same outlet, which may cause the beverages to be mixed if not desired. In addition, since one lid is installed on one outlet so that different beverages stored in the divided internal space are discharged according to the position of the lid, there is a problem that it is difficult to drink the beverage because the position of the hole must be precisely aligned. In addition, since only one beverage is discharged from one outlet, there is a disadvantage that only one person can drink two types of beverages even though they are stored.

Conventional tumblers form a single storage space, and users who prefer two types of beverages, such as iced coffee and hot coffee, juice and milk, or coffee and tea, have to carry around two tumblers, which results in poor portability. Accordingly, a tumbler that forms a double internal insulation space by forming a double internal insulation space so that two types of beverages can be stored has been disclosed.

However, since such a tumbler simply divides a single storage space, there is a problem that when drinking a beverage, the beverage is discharged through the same outlet, which may cause the beverages to be mixed if not desired. In addition, since one lid is installed on one outlet so that different beverages stored in the divided internal space are discharged according to the position of the lid, there is a problem that it is difficult to drink the beverage because the position of the hole must be precisely aligned. In addition, since only one beverage is discharged from one outlet, there is a disadvantage that only one person can drink two types of beverages even though they are stored.

The tumbler according to the present invention includes a first compartment and a second compartment, each of which forms a receiving space and is opened and closed by different lids, so that two different types of beverages can be received in each compartment, and the beverages in each of the two compartments can be selectively consumed or consumed simultaneously as needed.

In addition, since the tumbler according to the present invention includes a joining cover portion that mutually joins the first and second compartments in which different beverages are stored, convenience can be increased as two beverages can be easily carried.

Hereinafter, a preferred embodiment of a tumbler according to the present invention will be described in detail with reference to the drawings.

Figures 1 and 2 illustrate a tumbler according to one embodiment of the present invention.

Referring to FIGS. 1 and 2, a tumbler according to the present invention includes a main body (10) including a first divider (20) forming a first receiving space (21) that is opened and closed by a first lid (23), and a second divider (40) that is formed separately from the first divider (20) and forms a second receiving space (41) that is opened and closed by a second lid (43); and a coupling cover portion (50) that is provided on at least one side of the main body (10) and mutually couples the first divider (20) and the second divider (40).

Specifically, the main body (10) includes a first divider (20) and a second divider (40) that form each receiving space, and if the first divider (20) and the second divider (40) are not simply mutually partitioned but each partitions a different receiving space, the shape is not particularly limited. However, as a preferred example, when the first divider (20) and the second divider (40) are fixed in contact with each other by the coupling cover part (50) so that the user can easily grasp them, the main body (10) may have a cylindrical shape as illustrated in the drawing. Alternatively, the main body (10) may have an overall shape like a conventional tumbler. For example, it may have a cylindrical shape with a lower diameter smaller than an upper diameter.

The first compartment (20) and the second compartment (40) form a first receiving space (21) and a second receiving space (41), respectively, and each receiving space is opened and closed by the first lid (23) and the second lid (43), respectively. The first compartment (20) and the second compartment (40) can form a first receiving space (21) and a second receiving space (41) with an open top so as to maximize the amount of beverage accommodated. The first lid (23) and the second lid (43) are respectively connected and separated at the open tops so that the first and second receiving spaces (41) can be opened and closed independently of each other.

As shown in the drawing, since the main body (10) has a cylindrical shape, the first divider (20) and the second divider (40) may have a semicircular cross-section shape perpendicular to the longitudinal direction (height).

At this time, the angle formed by the virtual plane (B) formed by the contact area where the first and second dividers (20)(40) come into contact with each other and the virtual plane (A) formed by the longitudinal ends of the main body (10) may be vertical, as shown in Fig. 2. At this time, vertical may mean (90°±5).

In contrast, the angle formed by the virtual plane (B) of contact formed by the contact area where the first and second dividers (20) (40) come into contact with each other and the virtual plane (A) formed by the longitudinal ends of the main body (10) may be greater than or less than the vertical.

The first and second dividers (20)(40) can be applied to any existing tumbler material without any particular limitations, and the first and second dividers (20)(40) can be provided with the same material or with different materials.

The first and second leads (23) (43) are not particularly limited as long as they can open and close the first and second receiving spaces (41), respectively. As shown in the drawing, the first and second leads (23) (43) can be provided with an additional auxiliary opening and closing member to make drinking easier for the user.

The coupling cover part (50) couples the first compartment (20) and the second compartment (40) of the main body (10) to make the tumbler easy to carry. The coupling cover part (50) is not particularly limited as long as it is provided on at least one side of the first compartment (20) and the second compartment (40) and can fix the first compartment (20) and the second compartment (40). Preferably, the coupling cover part (50) may include an upper coupling cover (51) that is screw-connected to the upper part of the main body (10); and a lower coupling cover (55) that is screw-connected to the lower part of the main body (10). Alternatively, only the upper coupling cover (51) or only the lower coupling cover (55) may be provided.

The upper coupling cover (51) is screw-connected to the upper part of the main body (10), and may be provided in a shape corresponding to the upper part of the cylindrical main body (10). That is, as illustrated in the drawing, it may have a diameter corresponding to the upper part of the main body (10) and a cylindrical shape with an open lower end. At this time, when the first divider (20) and the second divider (40), which are the main body (10), are in close contact with each other, a screw groove or screw line (13) that can be screw-connected with the upper coupling cover (51) is formed on the upper part of the outer surface forming the main body (10), and a screw groove or screw line (53) that is screw-connected with the screw groove or screw line (13) formed on the main body (10) may be formed on the inner surface of the upper coupling cover (51). As shown in the drawing, the screw grooves or screw lines (13) formed in the first divider (20) and the second divider (40) are mutually continuous, so that the first divider (20) and the second divider (40) can be simultaneously screw-connected and fixed to a single upper coupling cover (51).

As described above, the first and second leads (23)(43) may be provided on the upper ends of the first divider (20) and the second divider (40), respectively, and at this time, the upper coupling cover (51) may further include a pressing projection (55) protruding in the direction of the first and second leads (23)(43) on the inner side corresponding to the upper end of the main body (10). When such an upper coupling cover (51) is coupled to the upper part of the main body (10), the pressing projection (55) may apply pressure in the direction of closing the first lead (23) and the second lead (43). Accordingly, the first lead (23) and the second lead (43) may be prevented from being separated from the first divider (20) and the second divider (40) even in the event of a strong external impact, thereby preventing leakage of the beverage contained in the main body (10).

The lower coupling cover (55) is screw-connected to the lower part of the main body (10), and may be provided in a shape corresponding to the lower part of the cylindrical main body (10). That is, as illustrated in the drawing, it may have a diameter corresponding to the lower part of the main body (10) and a cylindrical shape with an open upper end. At this time, when the first divider (20) and the second divider (40), which are the main body (10), are in close contact with each other, a screw groove or screw line (17) that can be screw-connected with the lower coupling cover (55) is formed on the lower part of the outer surface forming the main body (10), and a screw groove or screw line (57) that is screw-connected with the screw groove or screw line (17) formed on the main body (10) may be formed on the inner surface of the lower coupling cover (55). As shown in the drawing, the screw grooves or screw lines (17) formed in the first divider (20) and the second divider (40) are mutually continuous, so that the first divider (20) and the second divider (40) can be simultaneously screw-connected and fixed to a single lower coupling cover (55).

A bottom-joining cover (55) like this can accommodate condensation generated by the temperature of a beverage contained in the main body (10) inside. Accordingly, it is possible to drink the beverage more comfortably.

FIG. 4 illustrates a tumbler according to another embodiment of the present invention.

As shown in Fig. 4, an insulating member (60) may be further included in the contact area where the first divider (20) and the second divider (40) come into contact.

The insulating member (60) is not particularly limited as long as it is known as a conventional insulating material. At this time, the insulating member (60) may be provided in a detachable manner as shown in the drawing, but, of course, it may be provided by being attached to either the first divider (20) or the second divider (20). Alternatively, it may be attached to each of the first divider (20) and the second divider (40). In addition, it is of course possible for an insulating layer to be formed on at least one surface of the first divider (20) and the second divider (40).

In addition, as shown in FIG. 4, the tumbler of the present invention may further include a condensation prevention unit (70) provided in the main body (10) to prevent condensation due to a temperature difference by transferring the heat of the first separation container (20) and the second separation container (40) containing the liquid substance having a high temperature to the outer surface of the separation container containing the liquid substance having a low temperature.

The condensation prevention unit (70) is not particularly limited as long as it can transfer heat from a container containing a high-temperature liquid substance to the outer surface of a container containing a low-temperature liquid substance. At this time, the liquid substance may mean a liquid that can be contained in a tumbler. As a specific example, it may be a drinkable liquid substance such as coffee, juice, milk, shikhye, and water. As another example, it may be a liquid substance that cannot be consumed but must be carried.

Specifically, the condensation prevention member (70) may include a first heat transfer member (71) positioned to surround a receiving space of a divider container containing a liquid substance having a high temperature among the first divider container (20) and the second divider container (40), a second heat transfer member (73) positioned to surround an outer surface of a divider container containing a liquid substance having a low temperature among the first divider container (20) and the second divider container (40), and a heat connection member (75) extending from the first heat transfer member (71) and contacting at least one side of the second heat transfer member (73). Such a condensation prevention member (70) can receive heat from the high-temperature liquid substance to heat the surface of the divider container containing the low-temperature liquid substance, thereby preventing condensation from forming on the surface of the liquid substance having a relatively low temperature. Accordingly, more comfortable drinking can be possible.

At this time, the condensation prevention unit (70) may further include an auxiliary coupling unit (80) provided to the heat connecting member (75) and the second heat transfer member (73) to strengthen the bonding strength of the first divider (20) and the second divider (40), as shown in the drawing.

The auxiliary joint (80) may include a joint projection (81) protruding from one side of the heat connection member (75) that comes into contact with the second heat transfer member (73), and a joint groove (83) into which the joint projection (81) is inserted so as to be fittable into the outer side of the second heat transfer member (73) that comes into contact with the heat connection member (75).

In this way, a tumbler with an auxiliary joint (80) formed further assists the joining of the first dispensing device (20) and the second dispensing device (40), and can stably maintain the joining of the first dispensing device (20) and the second dispensing device (40) even when the joining cover part (50) is separated, making it easier to carry and use.

FIGS. 5 and 6 each illustrate a tumbler according to another embodiment. Referring to FIGS. 5 and 6, the tumbler according to the present invention may further include a bonding reinforcing member (90) provided in an area where the first divider (20) and the second divider (40) come into contact to mutually bond the first divider (20) and the second divider (40).

Specifically, referring to FIG. 5, the bonding reinforcing member (90) may include a bonding rib (91) formed by protruding from one side of one of the first divider (20) and the second divider (40), and a bonding channel (93) formed by being introduced into one side of the other divider that comes into contact with the divider on which the bonding rib (91) is formed and is slidably bonded to the bonding rib (91).

The joining rib (91) and the joining channel (93) are mutually slidably joined. Specifically, the joining rib (91) and the joining channel (93) are formed to be joined from the top to the bottom in the divider, and may have a length of 0.3L to 0.6L from the top to the bottom in the total length (L) of the first divider (20) and the second divider (40). Accordingly, when the user holds them, they can be stably joined to each other to jointly fix the first divider (20) and the second divider (40).

The coupling rib (91) and the coupling channel (93) may be formed directly on the first splitter (20) and the second splitter (40) as shown in FIG. 5, but alternatively, they may be formed on a separate member as shown in FIG. 6.

Specifically, it goes without saying that they can be formed on each of the connecting members (95) installed to surround the first divider (20) and the second divider (40) as shown in Fig. 6. At this time, it is more advantageous for the connecting member to be made of an insulating material to prevent condensation.

A tumbler including a reinforcing joint (90) like this can stably maintain the joint between the first splitter (20) and the second splitter (40) even when the joint cover (50) is separated, making it easier to carry and use.

Although the present invention has been described with reference to specific matters, limited examples, and drawings, these have been provided only to help a more general understanding of the present invention, and the present invention is not limited to the above examples, and those skilled in the art will appreciate that various modifications and variations may be made from this description.

Therefore, the idea of the present invention should not be limited to the described embodiments, and all things that are equivalent or equivalent to the claims described below as well as the claims are included in the scope of the idea of the present invention.
