Description

Technical Field

[0001] The present invention relates to the field of containers, and in particular to a container, a container system and a cover. Background Art

[0002] In some cases, containers for packaging beverages or food need to separate the two contents before opening, and mix the two contents after opening. For example, some containers for storing tea beverages such as herbal tea are constructed so that tea and water are mixed after opening to prevent the tea and water from mixing too early, affecting the taste of the tea beverage, or shortening the shelf life of the tea beverage. For another example, some containers for storing heated objects are constructed so that liquids such as water are mixed with self-heating agents after opening to meet consumers' heating needs before consumption and achieve self-heating function.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of the present invention.

[0053] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0054] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0055] In the description of the present invention, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0056] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] In the related art, in order to mix the two contents in the container after the container is opened, it is generally necessary to release one of the contents by needle puncture or pulling a rope after opening the container, which has a relatively complex structure and cumbersome operation.

[0058] Take the container used to realize the self-heating function as an example. As a common structure in the related art, the container includes a container body, a lid, a food box, a water bag and a self-heating bag. The upper end of the container body is open, and the lid is covered on the opening of the container body. The food box, the water bag and the self-heating bag are all placed in the container body, and a drawstring is provided on the water bag. Before eating, consumers need to open the water bag by pulling the rope first, so that water flows out of the water bag and mixes with the self-heating agent in the self-heating bag to achieve the heating of the food in the food box. On the one hand, when using, not only the lid needs to be opened, but also the drawstring needs to be broken, which has many steps and low efficiency. On the other hand, it is difficult to open the water bag by drawing the rope, and the problem of failing to break the bag successfully often occurs. Consumers also need to tear the bag manually, which is inconvenient to operate and has a poor user experience. On the other hand, on the basis of the container body, the lid and the food box, additional water bags and drawstrings need to be set, and the structure is relatively complicated.

[0059] In view of the above situation, the present invention provides a container system 100 and a container 10 thereof to solve the problem that the operation of mixing two contents in the related art is relatively complicated, and facilitate the mixing of the two contents.

[0060] Figure 1-7 The container system 100 and the container 10 of the present invention are shown as examples.

[0061] Reference Figure 1-7 In the present invention, the container system 100 includes a container 10, a first content 20, a second content 30, and the like.

[0062] The container 10 is used to store the first content 20 and the third content 30, etc., and is used to control the first content 20 and the second content 30 to be mixed only when needed.

[0063] For example, in some embodiments, the first content 20 is water, the second content 30 is tea or other condiments, and the container 10 controls the first content 20 and the third content 30 to be mixed only when the consumer needs to drink, so as to meet the needs of tea beverages and other beverages to improve the taste and extend the shelf life. In this case, the container 10 can be called a beverage container, such as a beverage bottle or a beverage can.

[0064] For another example, in some other embodiments, the first content 20 is a self-heating agent, and the second content 30 is a liquid such as water. The container 10 controls the first content 20 and the third content 30 to be mixed only when the consumer needs to eat or drink the heated object, so as to realize the self-heating function of solid or liquid food and meet the consumer's heating and eating needs. At this time, the container 10 can be called a self-heating container, such as a self-heating can or a self-heating box. The self-heating agent includes at least one of a self-heating sheet and a self-heating powder. Among them, the self-heating sheet is more convenient to control the heat release rate to prevent the heat from being released too quickly when mixed with liquids such as water, so as to avoid a sharp increase in pressure due to the excessive release of heat, causing a safety accident, or affecting the heating effect due to the excessive release of heat.

[0065] In order to enable the container 10 to have the above-mentioned storage and mixing control functions, refer to Figure 1-7 In some embodiments, the container 10 includes a first storage element 1, a cover 3, a limiting device 4, and the like.

[0066] The first storage element 1 has an opening 11 at the top, and the first content 20 is stored inside. In some embodiments, the first storage element 1 is constructed as a hollow rotating body, such as a hollow cylindrical can. The first content 20 is placed directly in the first storage element 1, or Figure 1 , Figure 3 and Figure 5 As shown, the first content 20 is first placed in a packaging member 50 (such as a bag or a pouch) and then placed in the first storage member 1. Placing the first content 20 in the packaging member 50 is more conducive to utilizing the packaging member 50 to protect the second content 30 before the first content 20 and the second content 30 are mixed, thereby effectively preventing the first content 20 from reacting prematurely.

[0067] The lid 3 covers the opening 11 and is sealed. The interior is used to store the second content 30. Under the action of the limiting device 4, the lid 3 cooperates with the first storage element 1 to control the release of the second content 30 into the first storage element 1, so as to control the mixing of the first content 20 and the second content 30.

[0068] Among them, refer to Figure 1-2 as well as Figure 6-7 In some embodiments, the cover 3 includes a first cover body 31 and a second cover body 32. The first cover body 31 is arranged to be movable upward relative to the first storage element 1. The second cover body 32 is connected below the first cover body 31 and is located in the first storage element 1. In addition, a limiting device 4 is provided between the second cover body 32 and the first storage element 1. The limiting device 4 is used to limit the second cover body 32 from moving upward together with the first cover body 31.

[0069] Based on the above arrangement, when the first cover 31 tends to move upward under the action of an external force, the second cover 32 is constrained by the limiting device 4 and cannot move upward with the first cover 31, so that deformation occurs between the second cover 32 and the first cover 31. When the first cover 31 moves upward to a certain extent, Figure 3-5 , the first cover body 31 and the second cover body 32 are broken and separated from each other. At this time, the sealing state of the cover 3 is destroyed, and the second content 30 stored in the cover 3 flows out from the cover 3, enters the first storage element 1, and mixes with the first content 20 in the first storage element 1.

[0070] It can be seen that when the first cover body 31 moves upward, the limiting device 4 limits the second cover body 32 from moving upward together with the first cover body 31, so that the second cover body 32 is separated from the first cover body 31, thereby controlling the mixing of the second content 30 inside the cover 3 and the first content 20 in the first storage element 1.

[0071] Since the mixing of the first content 20 and the second content 30 can be controlled while opening the first cover 31 without taking additional methods such as pulling ropes or needle puncture, there are fewer steps, the operation is simpler, the efficiency is higher, and it is beneficial to improve the user experience.

[0072] Furthermore, the second content 30 is released into the first storage element 1 by moving the first cover body 31 upward to separate from the second cover body 32. This has a higher success rate than methods such as pulling a rope, and is easier to achieve a faster and more complete release of the second content 30 than methods such as acupuncture, thereby avoiding the effects of the release adequacy and efficiency of the second content 30 on the release due to, for example, a small needle hole.

[0073] At the same time, the storage and release control of the second content 30 is realized by utilizing the original lid 3 of the container 10, so that there is no need to set up additional storage components for storing the second content 30 and bag-breaking devices such as drawstrings or puncture needles outside the lid 3. Therefore, the structure is relatively simple.

[0074] Among them, refer to Figure 1 and Figure 6-7 The top of the first cover 31 is closed, and the bottom is connected to the second cover 32. Figure 2 and Figure 6-7 In some embodiments, the first cover 31 is threadedly connected to the first storage element 1 to achieve an upwardly movable arrangement relative to the first storage element 1. Specifically, Figure 2 and Figure 6As shown, an external thread 311a is provided on the side wall of the first cover 31, and an internal thread 12 that cooperates with the external thread 311a is provided on the side wall of the first storage element 1. In this way, with the cooperation of the external thread 311a and the internal thread 12, the first cover 31 and the first storage element 1 can be threadedly connected, and the first cover 31 can be conveniently moved upward relative to the first storage element 1 by screwing, thereby realizing the tearing and separation of the first cover 31 and the second cover 32.

[0075] Since the first cover 31 is threadedly connected to the first storage member 1, the helical lead angle can help the first cover 31 to move upward relative to the first storage member 1. The first cover 31 not only moves upward under the external force applied by the user, but also moves upward under the action of the thread lead angle. Therefore, it is easier for the first cover 31 to move upward relative to the first storage member 1 to separate from the second cover 32. At the same time, when the first cover 31 is threadedly connected to the first storage member 1, the first cover 31 can be opened by simply twisting the first cover 31, which is more in line with the user's habit of opening the cover and helps to improve the user experience.

[0076] In order to further facilitate the screwing of the first cover 31, refer to Figure 1-5 In some embodiments, the first cover 31 is further provided with an anti-slip portion 311b. The anti-slip portion 311b is used to increase the friction during screwing and prevent the screwing from slipping, so as to make the screwing process more labor-saving. The anti-slip portion 311b is, for example, arranged above the aforementioned external thread 311a so as to be exposed outside the opening 11 in the assembled state, so as to facilitate the user to contact and apply force.

[0077] Among them, refer to Figure 2 and Figure 4 In some embodiments, the anti-slip portion 311 b specifically includes anti-slip teeth 312 c. A plurality of anti-slip teeth 312 c are distributed side by side along the circumference of the first cover body 31 .

[0078] Reference Figure 1 and Figure 6 The top end of the second cover body 32 is connected to the first cover body 31 , and the lower end is closed, so that the entire cover 1 is in a sealed state before breaking, thereby achieving reliable storage of the second content 30 .

[0079] In order to achieve the closure of the bottom end of the second cover 32, refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, a sealing film 33 is provided at the bottom end of the second cover body 32 , and the sealing film 33 seals the bottom end of the second cover body 32 .

[0080] Compared with other ways of closing the bottom end of the second cover body 32, such as the second cover body 32 having a bottom wall integrated with the side wall, the sealing film 33 is used to close the bottom end of the second cover body 32. On the one hand, when the first cover body 31 is not opened, the lid 3 can have a tight sealing effect to prevent the second content 30 from accidentally leaking; on the other hand, after the first cover body 31 is opened, the first cover body 31 and the second cover body 32 are separated, and the first content 20 and the second content 30 are fully mixed, it is convenient to take out the second cover body 32. For example, due to the provision of the sealing film 33, the second cover body 32 separated from the first cover body 31 is relatively easy to deform. Therefore, the user can directly pick up the second cover body 32 to take it out. Alternatively, since the strength of the sealing film 33 is relatively low and it is easy to be broken, the user can first break the sealing film 33 and then grasp and apply force from the broken part of the sealing film 33 to take out the second cover body 32. At this time, it is more convenient for the user to apply force to the second cover body 32.

[0081] In addition, refer to Figure 1-5 as well as Figure 6-7 In some embodiments, the height of the second cover 32 is smaller than that of the first cover 31. For example, the height of the second cover 32 is designed to be 1 / 10-1 / 3 of the height of the first cover 31, specifically 1 / 6-1 / 4, more specifically 1 / 6, 1 / 5, or 1 / 4. The advantage of such a setting is that, due to the lower height of the second cover 32, the second content 30 stored in the second cover 32 is relatively small, and most of the second content 30 is located above the second cover 32. Therefore, after the first cover 31 and the second cover 32 are separated, most of the second content 30 can flow out smoothly from the fracture under the action of gravity, thereby facilitating a more complete release of the second content 30. It can be understood that the "height" here refers to the dimension along the axial direction of the cover 3.

[0082] In order to prevent the second cover 32 from moving upward with the first cover 31, refer to Figure 2 and Figure 6-7 In some embodiments, the limiting device 4 includes a first limiting portion 41 and a second limiting portion 42, the first limiting portion 41 is arranged on the second cover body 32, and the second limiting portion 42 is arranged on the first storage element 1, and is connected to the first limiting portion 41 by being snapped or hooked.

[0083] Among them, when the clamping method is adopted, in some embodiments, the first limiting portion 41 and the second limiting portion 42 are constructed as mutually matching clamping grooves and clamping columns, and in other embodiments, the first limiting portion 41 and the second limiting portion 42 are constructed as mutually matching clamping rings.

[0084] For example, refer to Figure 2-5 as well as Figure 6-7In some embodiments, the first limiting portion 41 includes a first clamping ring 411 , the second limiting portion 42 includes a second clamping ring 421 , and the first clamping ring 411 is clamped under the second clamping ring 421 .

[0085] Since the first snap ring 411 is clamped under the second snap ring 421, when the first cover body 31 is opened, the second snap ring 421 blocks the first snap ring 411, so that the limiting device 4 can limit the second cover body 32 from moving upward together with the first cover body 31, thereby facilitating the breaking and separation of the first cover body 31 and the second cover body 32.

[0086] The cross-sectional shape of the second snap ring 421 can be various. Figure 4 In some embodiments, the cross section of the second clamp ring 421 is triangular. Figure 6 and Figure 7 In some other embodiments, the cross section of the second snap ring 421 is trapezoidal. For another example, in some embodiments not shown in the figure, the cross section of the second snap ring 421 is rectangular or other shapes.

[0087] And, refer to Figure 4-Figure 7 In some embodiments, the second snap ring 421 includes a guide surface 421a, which is inclined downward to guide the first snap ring 411 to move downward. Figure 4-5 ) or trapezoidal ( Figure 6-7 ), the upper surface of the second snap ring 421 is configured as a downwardly inclined guide surface 421a. In this way, the second snap ring 421 can not only limit the upward movement of the second cover 32, thus smoothly releasing the second content 30, but also guide the cover 3 to be inserted downward into the first storage element 1, thus facilitating the installation of the cover 3 on the first storage element 1. Specifically, on the one hand, in the process of closing the cover 3 on the first storage unit 1, the guide surface 421a of the second snap ring 421 guides the first snap ring 411 on the second cover body 32, and guides the first snap ring 411 to smoothly reach under the second snap ring 421, so that the cover 3 can be smoothly inserted into the first storage unit 1 to achieve reliable closing; on the other hand, after being inserted into place, the first snap ring 411 is stuck under the second snap ring 421, so that when the first cover body 31 is opened upward, the second snap ring 421 can prevent the second cover body 32 from moving up synchronously by blocking the first snap ring 411, thereby causing the first cover body 31 and the second cover body 32 to be pulled apart, thereby achieving the smooth release of the second content 30.

[0088] It can be seen that the second retaining ring 421 is constructed with a downwardly inclined guide surface 421a, which not only facilitates the downward insertion of the second cover body 32, but also limits the upward movement of the second cover body 32, so that the cover 3 is easy to assemble with the first storage element 1 and can reliably control the release of the first content 30.

[0089] In addition, refer to Figure 3 and Figure 5 as well as Figure 6 and Figure 7 In some embodiments, at least one of the first snap ring 411 and the second snap ring 421 includes at least two snap ring segments 411a, and the at least two snap ring segments 411a are spaced apart along the circumference of the cover 3, that is, the first snap ring 411 and / or the second snap ring 421 is no longer a full circle of snap rings, but includes several snap ring segments 411a that are disconnected from each other. Figure 3 and Figure 5 In the illustrated embodiment, the first snap ring 411 includes a plurality of snap ring segments 411a, and the second snap ring 421 is a full circle snap ring. Figure 6-7 In the illustrated embodiment, the second snap ring 421 includes a plurality of snap ring segments 411a, while the first snap ring 411 is a full circle snap ring. For another example, in some other embodiments not shown, the first snap ring 411 and the second snap ring 421 each include two or more snap ring segments 411a.

[0090] The advantage of providing the segmented clamping ring section 411a is that it is convenient to form an exhaust channel between the first clamping ring 411 and the second clamping ring 421, which plays the role of exhaust and pressure reduction, so as to discharge the rapidly expanding gas in the first storage element 1, prevent excessive pressure in the container 10, and improve the safety of the container 10.

[0091] For example, when the first content 20 is a self-heating agent, the first content 20 and the second content 30 will generate heat when mixed. Especially in the initial stage of mixing, it is possible to release more heat instantaneously, causing the gas in the first storage element 1 to expand rapidly and the pressure to rise rapidly. In this case, the rapidly expanding gas can escape outward from the interval between adjacent clamping ring segments 411a and the gap between the first clamping ring 411 and the second clamping ring 421 (due to processing accuracy and other reasons, there is inevitably a gap between the first clamping ring 411 and the second clamping ring 421), thereby achieving the smooth discharge of the rapidly expanding gas in the first storage element 1, effectively controlling the pressure in the first storage element 1, preventing the container 10 from exploding due to excessive pressure and other safety accidents, and improving the heating safety of the container 10.

[0092] Furthermore, by configuring the first snap ring 411 to include several snap ring segments 411a that are disconnected from each other, an exhaust channel is formed between the first snap ring 421. After the first cover body 31 and the second cover body 32 are broken, the overall sealing of the container 10 is less affected, and the container 10 as a whole can still maintain good sealing, which is beneficial to prevent the excessive dissipation of heat generated by the mixing of the first content 20 and the second content 30, and further beneficial to achieving better heating effect and higher heating efficiency.

[0093] It can be seen that by constructing the first clamping ring 411 and / or the second clamping ring 421 into several separate clamping ring segments 411a, it is possible to achieve safe discharge of excess gas while ensuring a good heating effect.

[0094] In order to more conveniently realize the pulling off of the first cover 31 and the second cover 32, refer to Figure 2 and Figure 6 In some embodiments, the first cover body 31 includes a main body 311 and a weak portion 312. The external thread 311a and the anti-slip portion 311c are both provided on the main body 311. The weak portion 312 connects the main body 311 and the second cover body 32, and is a connecting portion between the first cover body 31 and the second cover body 32. Moreover, the wall thickness of the weak portion 312 is less than the wall thickness of the main body 311.

[0095] By providing a thinner weak portion 312 on the first cover 31, and connecting the first cover 31 to the second cover 32 through the weak portion 312, it is helpful to reduce the force required to break the first cover 31 and the second cover 32, so that the first cover 31 and the second cover 32 are more likely to break during the opening process of the first cover 31, and it is further convenient to control the release of the second content 30. At the same time, the provision of the weak portion 312 is also more conducive to controlling the breaking position of the first cover 31 and the second cover 32, so that when the first cover 31 is opened, the first cover 31 can be reliably separated from the second cover 32 at the weak portion 312.

[0096] And, refer to Figure 3-5 In some embodiments, the weak portion 312 includes a first weak portion 312a and a second weak portion 312b, wherein the first weak portion 312a is arranged around the circumference of the cover 3, and the second weak portion 312b is extended from the first weak portion 312a to one side of the second cover 32, for example, to the lower part of the top of the second cover 32, and specifically to the middle and lower part of the second cover 32, close to the bottom of the second cover 32. Based on this, in the process of opening the first cover 31, not only the first cover 31 and the second cover 32 can be completely separated, but also the groove 32a left by the tearing of the second weak portion 312b can be formed on the second cover 32, so that not only the second content 30 in the first cover 31 can flow out smoothly, but also most of the second content 30 in the second cover 32 can flow out smoothly from the groove 32a, effectively reducing the second content 30 remaining in the second cover 32, and achieving a more sufficient release of the second content 30.

[0097] The number of the second weak portions 312b is not specifically limited, and may be one, two or more.

[0098] Meanwhile, the shape of the second weak portion 312b is not specifically limited. Figure 3 and Figure 5 In some embodiments, the second weak portion 312b is configured to be semicircular, and accordingly, the groove 32a formed after the fracture is also semicircular. However, it should be understood that in other embodiments not shown, the second weak portion 312b may also be in various other shapes such as a triangle or a rectangle.

[0099] In addition, refer to Figure 1-5 When the container 10 is a self-heating container, in some embodiments, the container 10 includes a second storage element 2 in addition to the first storage element 1 and the lid 3. The second storage element 2 is disposed in the first storage element 1, which is sealed and is used to accommodate the heated object 40. At this time, the first content 20 can be disposed between the outer wall of the first storage element 1 and the inner wall of the second storage element 2. In this way, the heated object 40 placed in the second storage element 2 can be heated by the heat released by the mixing of the first content 20 and the second content 30, thereby realizing the self-heating function.

[0100] Among them, in order to achieve better heating effect, refer to Figure 1 , Figure 3 and Figure 5 In some embodiments, the second storage element 2 is arranged above the first content 20. This arrangement of the second storage element 2 on top and the first content 20 on the bottom is more in line with the upward flow of hot air, so that the heat released by the first content 20 after contact with the second content 30 can more fully heat the heated object 40 in the second storage element 2, thereby obtaining a better heating effect and a higher heating efficiency.

[0101] In addition, in the case where the second storage element 2 is provided, in order to facilitate the second content 30 to flow to the first content 20 and mix with the first content 20, refer to Figure 1 , Figure 3 and Figure 5 In some embodiments, a gap 5 is provided between the side wall of the second storage element 2 and the side wall of the first storage element 1, so that after the first cover body 31 and the second cover body 32 are broken, the second content 30 flowing out of the cover 3 can flow to the first content 20 more smoothly through the gap 5 and mix with the first content 20, which is convenient and efficient.

[0102] In addition, refer to Figure 3 and Figure 5 as well as Figure 7 In some embodiments, after being separated from the first cover body 31, the second cover body 32 remains in the first storage element 1 for a certain period of time, and is used to provide a relatively sealed environment for the mixing of the first content 20 and the third content 30, so as to prevent the heat generated by the mixing from being lost too quickly and improve the heating effect.

[0103] For example, refer to Figure 2 , Figure 4 and Figure 5 In some embodiments, the first storage element 1 includes a supporting portion 13, and the supporting portion 13 supports the second cover 32 after the second cover 32 is separated from the first cover 31. Based on this, after the second cover 32 is separated from the first cover 31, it can be supported by the supporting portion 13, effectively preventing the second cover 32 from falling or tilting excessively, so that the second cover 32 can be kept above the second storage element 2 more stably, and the space below the second cover 32 is sealed to a certain extent, slowing down the heat loss rate, and facilitating heating the heated object 40 to a predetermined temperature in a shorter time.

[0104] Specifically, Figure 2 and Figure 4 as well as Figure 6-7 As shown, the supporting portion 13 includes, for example, a necking portion 131, the inner diameter of the necking portion 131 decreases from top to bottom, and the inner diameter of the bottom end of the necking portion 131 is equal to or smaller than the outer diameter of the second cover 32. Figure 1 and Figure 6 As shown, in some embodiments, the necking portion 131 is arranged below the second limiting portion 42. Figure 1 As shown, in some embodiments, the necking portion 131 is arranged above the second storage element 2 to support the second cover body 32 separated from the first cover body 31 above the second storage element 2 .

[0105] Compared with the case where the supporting portion 13 adopts other structural forms, the advantage of using the necked portion 131 to support the second cover body 32 is that the necked portion 131 can not only limit the falling of the second cover body 32, but also allow the second cover body 32 to move up a certain distance. This makes it possible for the container 1 to achieve a better heating effect and realize self-control of pressure after the lid 3 is pulled off, thereby effectively reducing the risk of safety accidents caused by excessive pressure. Specifically, after the lid 3 is pulled off and the second cover body 32 is separated from the first cover body 31, the second cover body 32 will fall a short distance and be supported by the necked portion 131 and will no longer continue to fall. On the one hand, when the pressure in the first storage element 1 is relatively small, the second cover body 32 remains supported by the necked portion 131 and is in contact with the necked portion 131, forming a certain seal therebetween, which can prevent heat from being lost too quickly and improve the heating effect. On the other hand, when the pressure in the first storage element 1 is too high due to the violent expansion of the gas, the second cover body 32 can be lifted up by the gas and move upward to the position where the first retaining ring 411 is re-engaged with the second retaining ring 421, so that the aforementioned exhaust channel is re-formed between the first retaining ring 411 and the second retaining ring 421 to exhaust and reduce the pressure, effectively control the pressure, and improve safety.

[0106] In summary, in the present invention, the container 10 has a simple structure and can safely, conveniently and reliably control the instant mixing of two contents.

[0107] In addition, in order to facilitate the user to eat or drink the food or beverage in the container 10, refer to Figure 6 and Figure 7 In some embodiments, the first cover 31 is provided with a tableware storage portion 34, which is used to accommodate tableware 6. The tableware 6 here includes, for example, a spoon 61, chopsticks or a straw and other dining utensils. In this way, the tableware 6 is installed on the cover 3, and the user can directly take it off the cover 3 when it needs to be used, without having to look for it elsewhere, which is convenient and quick.

[0108] The tableware storage portion 34 includes, for example, a convex portion or a concave portion, and is connected to the tableware 6 by, for example, a clamping or bonding method.

[0109] For example, refer to Figure 7 In some embodiments, the tableware storage portion 34 includes a receiving groove 341. The receiving groove 341 is, for example, recessed downward from the top wall of the first cover 31. The tableware 6 is snapped into the receiving groove 341 to be fixed, or the tableware 6 is directly placed in the receiving groove 341, and then the notch is closed to store the tableware 6. By providing the receiving groove 341, the tableware 6 does not need to completely protrude from the cover 3, so the structure is more compact and beautiful, which is conducive to reducing the overall height of the container 10.

[0110] Among them, refer to Figure 7 In some embodiments, the receiving groove 341 includes an arc groove 341a, and the tableware storage portion 34 is more suitable for storing tableware 6 with a circular portion, an elliptical portion or other circular portions, such as a spoon 61. For example, when the tableware 6 is a spoon 61, the arc groove 341a can better accommodate the spoon head 612 of the spoon 61.

[0111] And, refer to Figure 7 In some embodiments, the receiving groove 341 includes two arc grooves 341a, and the two arc grooves 341a are connected to each other. The advantage of this arrangement is that, on the one hand, it is convenient to put tableware 6 such as a spoon 61 into any one of the two side arc grooves 341a, and the orientation requirement of the tableware 6 when putting in is reduced. For example, Figure 7In the embodiment, the spoon 61 can be placed with the spoon head 612 on the right and the spoon handle 611 on the left, or vice versa, with the spoon head 612 on the left and the spoon handle 611 on the right. No matter which posture is used, the spoon 61 can be successfully placed in the receiving groove 341, which is simple and convenient. On the other hand, it is also convenient to take out the tableware 6. For example, for a spoon 61 with an arc-shaped spoon head 612 at one end and a straight spoon handle 611 at the other end, after it is placed in the receiving groove 341, the arc-shaped groove 341a for placing the spoon handle 611 is not occupied by the spoon handle 611, but there is still residual space between the spoon head 612 and the spoon handle 611, which can be used to grasp or buckle the spoon handle 611, so that the spoon 61 can be easily taken out.

[0112] The above description is only an exemplary embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
