The present invention provides a container, and a detailed structure of the container according to an exemplary embodiment of the present invention will be described in detail below with reference to fig. 1 to 3. In the drawings, like reference numerals refer to like parts throughout.

Fig. 1 is a longitudinal sectional view of a container in a state where an opening closure is not yet closed on an outer case according to an exemplary embodiment of the present invention, and fig. 2 is a longitudinal sectional view of the container in a state where the opening closure is closed in fig. 1. Fig. 3 is a partially enlarged view of the structure in circle I of fig. 2. As shown in fig. 1 and 2, the container of the present invention may include an inner container 100, an outer container 600, and an opening cover 200, wherein the inner container 100 and the outer container 600 respectively have a first opening 103 and a second opening 601, the opening cover 200 includes an inner cylinder 201, an outer cylinder 202 sleeved on the outer circumference of the inner cylinder 201, and a connection part 203 connected between the inner cylinder 201 and the outer cylinder 202, the inner cylinder 201, the outer cylinder 202, and the connection part 203 surround to form a ring groove 300 extending along the circumferential direction of the container, the ring groove 300 may cover the first opening 103 and the second opening 601, the ends of the first opening 103 and the second opening 601 are inserted into the ring groove 300, and the outer cylinder 202 is provided with a thread 700 or a rib (not shown) for connecting to a container lid. The ring groove 300 can cover the gap between the first opening 103 and the second opening 601, which improves the appearance of the product and prevents bacteria from growing between the gaps.

As an example, the outer cylinder 202 may have an axial length greater than that of the inner cylinder 201, and the second opening 601 is covered by the outer cylinder 202, thereby providing an aesthetic appearance, and providing sufficient space for the screw 700 or the rib on the outer surface of the outer cylinder 202 for connection with the container cover. Under the condition that the opening part covering cover 200 is made of titanium materials, the appearance of the top of the product is made of metal titanium, and a user is in contact with the titanium when using the cover, so that healthy drinking is facilitated.

As an example, the inner container 100 and the outer casing 600 may respectively have an inner cavity, the inner container 100 may be placed into the inner cavity of the outer casing 600, and the outer casing 600 may protect the inner container 100 from being accidentally damaged by an external force. The material hardness of the outer case 600 may be greater than that of the inner container 100, or the material toughness of the outer case 600 may be greater than that of the inner container 100.

As an example, the first opening 103 and the second opening 601 may be respectively in a cylindrical shape, the outer cylinder 202 and the inner cylinder 201 are both in a cylindrical shape, the width of the ring groove 300 may approximately match the overall thickness of the first opening 103 and the second opening 601, and the ring groove may cover the inner side of the first opening 103 and the outer side of the second opening 601 from top to bottom, that is, the ring groove may wrap the first opening 103 and the second opening 601 to cover the gap between the inner container 100 and the outer shell 600 at the opening of the container, so as to prevent the occurrence of a gap near the top end of the opening of the container, and provide an aesthetic property, and prevent the occurrence of a gap to promote bacteria.

As shown in fig. 1 to 3, the connection form of the container cover and the outer cylinder 202 may have a case where the container cover may have an internal thread and the outer cylinder 202 may be provided with a thread 700 to enable a screw connection between the container cover and the outer cylinder 202. The container cover is provided with a clamping groove, the outer barrel 202 is provided with a clamping rib, and the clamping groove and the clamping rib are matched to form a clamping buckle connection.

It should be noted that, when the outer housing 600 is connected to the outer cylinder 202, the outer cylinder 202 may cover the second opening 601 entirely or partially, and it is only necessary that the mouth is in contact with the outer cylinder 202 completely within the covered length of the outer cylinder 202 during drinking.

Alternatively, the joint between the lower end of the outer cylinder 202 and the outer casing 600 may be fixed by brazing, so as to further enhance the connection stability between the two, or may not be welded.

As an example, the connection portion 203 is integrally connected to the inner cylinder 201 and the outer cylinder 202, and the ring groove 300 is formed between the inner cylinder 201 and the outer cylinder 202 to be able to accommodate an opening portion of the container. The ring groove 300 is opened toward the first opening 103 and the second opening 601, and both the first opening 103 and the second opening 601 are inserted into the ring groove 300. When the ring groove 300 covers the container opening, the inner cylinder 201 is attached to the inner wall surface of the inner container 100, and the outer cylinder 202 is attached to the outer wall surface of the outer case 600, that is, the opening closing cover 200 has sufficient contact areas with the inner container 100 and the outer case 600, respectively, thereby improving the connection stability of the opening closing cover 200.

As an example, the outer case 600 further includes a case expansion part 602 located below the second opening part 601, a diameter of the case expansion part 602 is larger than a diameter of the second opening part 601, and a bottom end of the outer cylinder 202 extends to a step between the case expansion part 602 and the second opening part 601. The step has a supporting function for the outer cylinder 202, and can stabilize the connection between the opening cover 200 and the second opening 601. Except that, the step can be the slope setting, and the bottom of outer barrel 202 can support and lean on in step department, and can form conical joint clearance between the step, is favorable to brazing.

As shown in the figure, the outer casing 600 is disposed outside the inner container 100 in a spaced manner, and a space between the outer casing 600 and the inner container 100 is evacuated or filled with air. The gap between the outer casing 600 and the inner container 100 can play a certain role in buffering when the container is impacted from the outside, thereby reducing the damage to the inner container 100. Further, the outer shell 600 and the inner container 100 are arranged at intervals, so that the heat insulation effect of the container can be improved, and a user cannot be accidentally scalded under the condition that hot food is placed in the container, so that the use safety of the container is further improved.

In order to reduce the cost, the liner 100 may include a liner inner layer 110 and a liner outer layer 120, and the liner outer layer 120 and the liner inner layer 110 may be attached to each other and may be made of different materials. The inner liner outer layer 120 may be supported on the outer wall surface of the inner liner inner layer 110 to improve the overall structural strength of the inner liner 100. At present, the price of the titanium material is higher than that of other common metal materials, so that the strength of the inner container can be ensured and the manufacturing cost can be reduced by adopting a double-layer structural design.

As an example, the inner container outer layer 120 may be made of stainless steel or aluminum or copper; the inner liner layer 110 can be made of titanium material; the outer case 600 may be made of stainless steel or aluminum or copper; the opening closure 200 may be made of a titanium material. The inner layer 110 of the inner container, which needs to be in contact with an object placed therein, such as soup, can be made of titanium material, for example, but not limited to, titanium alloy material, so as to meet the core function of the product, i.e. titanium drinking water, and meet the requirement of health. The inner bag outer layer 120 does not contact with an object placed in the container, and does not contact with the mouth of a user, so that a common metal having a relatively low material cost can be selected to reduce the manufacturing cost of the container.

Thus, the inner liner layer 110 and the outer liner layer 120 are made of different materials, which not only ensures the structural strength of the inner liner 100, but also reduces the manufacturing cost of the container.

The outer casing 600 may be made of a material with good structural strength or toughness, such as, but not limited to, at least one of stainless steel, aluminum, and copper. Further, the outer shell 600 may be made of the same material as the inner container outer layer 120, which may reduce the variety of materials used for the container, further reduce the manufacturing cost, and facilitate the welding between the two. Since the outer case 600 does not contact food or water in the container, it may be made of a general material, and thus cost may be reduced. By way of example, the opening closure 200 may be made of a titanium material, such as, but not limited to, a titanium alloy, to increase corrosion resistance of the opening, and the portion of the opening that contacts water is a titanium material to promote drinking water health. Because the outer shell 600 is a non-titanium material, when drinking water, the part of the outer shell 600 contacting with the mouth is a non-titanium material, and can not reach complete titanium drinking water, therefore, the function of complete titanium drinking water can be realized through the covering of the outer cylinder 202, and the health is more facilitated.

In order to stably mount the opening cover 200, as shown in fig. 2, the inner container 100 has a transition structure, as shown in the figure, the first opening 103 is cylindrical, the inner container 100 may further include a cylindrical inner container neck 101 and an inner container transition 102, the inner container neck 101 has an inner diameter smaller than that of the first opening 103, the inner container transition 102 is connected between the top of the inner container neck 101 and the bottom of the first opening, and the axial bottom edge of the inner cylinder 201 extends to the inner peripheral surface of the inner container transition 102. The inner container transition part 102 can support and position the inner cylinder 201. The opening cover 200 is convenient to mount, not easy to shift and good in stability. And the inner cylinder 201 extends to the inner container excess part 102 to form smooth transition with the inner container excess part 102, so that objects are prevented from remaining on the inner wall surface of the inner container.

For example, the inner liner transition portion 102 may be tapered or curved, and a smooth transition may be formed between the inner liner transition portion 102 and the first opening 103 and between the inner liner transition portion 102 and the inner liner necking portion 101. The toper has the slope inclined plane, is favorable to the welded fastening in later stage, and the toper design has certain aesthetic property.

After the opening cover 200 is mounted, welding is required to fix the opening cover 200. Specifically, the axial bottom edge of the inner cylinder 201 and the inner container transition part 102 are connected by welding, and the axial bottom edge of the outer cylinder 202 and the outer wall of the outer casing 600 are connected by brazing. Brazing can fill gaps between structures, and then polishing treatment is carried out on the welded seams, so that the welded seams have attractiveness, specifically, the outer cylinder 202 and the outer shell transition part 620 are in smooth transition, gaps or wrinkles between the outer cylinder 202 and the outer shell transition part are avoided, and therefore dirt collection and dirt collection of the container can be avoided.

As shown in fig. 1 to 3, the top end of the first opening 103 and the top end of the second opening 601 are flush with each other, and the first opening 103 and the second opening 601 are attached to each other. The thickness of the opening part of the container can be reduced by mutually attaching the two parts, so that the drinking of a user is facilitated.

Note that the inner diameter of the outer cylinder 202 is the same as the diameter of the second opening 601, and the outer cylinder 202 is fitted around the outside of the second opening 601. The inner diameter of the first opening 103 is equal to the outer diameter of the inner cylinder 201, and the inner cylinder 201 is sleeved inside the first opening 103. With such an arrangement, the opening covering cover 200 can be well attached to the opening, thereby facilitating mutual fixation and improving the connection effect between the opening covering cover and the opening.

In summary, the container of the present invention has the inner container 100 and the outer casing 600, wherein the inner container 100 has a double-layer structure, and has the inner container outer layer 120 and the inner container inner layer 110, which are attached to each other, and the outer wall of the inner container outer layer 120 and the inner wall of the outer casing 600 are attached to each other, which is beneficial for drinking water. The container of the utility model also comprises an opening part covering cover 200, the opening part covering cover 200 comprises a ring groove 300, when the opening part covering cover 200 covers the opening part of the container, the ring groove 300 can cover the opening parts of the liner 100 and the outer shell 600, namely a first opening part and a second opening part, therefore, the gap between the liner inner layer 110 and the liner outer layer 120 can be covered, the container has aesthetic property, and impurities such as water can enter the gap to cause the problems of rusting, bacterium breeding and the like, the service life of the product is prolonged, and the container is also beneficial to the health of users.
