Description

[Technical field]

[0001] The present disclosure relates to containers, particularly closed containers. [Background technology]

[0002] A container is a basic device that is used to hold materials or liquids and is mainly a case. Traditionally, containers generally adopt screw or snap structure for connection and sealing. When using screw connection, the thread is easy to be damaged after long-term use, and when opening the lid, it is necessary to turn the container lid several times to open and close it, which is rather inconvenient.

[0003] The applicant first applied for a quick-open container, which uses a radially deforming elastic seal to seal the container lid and the container. To achieve this, the elastic seal needs to be deformed by the rotation of the rotary switch. In this case, the size of the rotary switch does not change, so the rotary switch is tight to turn during use, which is inconvenient. Therefore, it can only be used for small diameter containers to ensure smooth opening and closing during use. When the diameter of the container is large, as the elastic seal becomes larger, the pressure to deform the elastic seal also needs to be increased, so a larger force is required to open and close the container, which results in a poor user experience. Summary of the Invention

[0004] Based on the above, there is a need to provide a sealed container to address the problems in the prior art.

[0005] A sealed container is provided, the sealed container comprising a container and a container lid, the container lid comprising a lid body, a movable base movable up and down is provided on the underside of the lid body, an elastic seal is provided between the movable base and the lid body, the elastic seal is connected to the lid body or the movable base, when the movable base moves upward, the outer edge of the elastic seal is deformed outward by the action of the movable base and / or the lid body so as to become larger than the diameter of the sealing portion of the container, thereby preventing the movable base from continuing to move upward, and the movable base presses the elastic seal against the inner neck of the container to form a sealing portion, thereby realizing sealing between the container lid and the container, an opening and closing mechanism for opening and closing the container lid is provided on the upper side of the container lid, the opening and closing mechanism comprises a rotary switch and a sliding cover, when the rotary switch is rotated on the lid body, the movable base is moved up and down, the sliding cover is slidably connected to the rotary switch, the sliding cover slides relative to the rotary switch, and the length of the force arm of the rotary switch can be increased.

[0007] In one embodiment, a position limiting portion is provided on the upper side of the lid body, and when the sliding cover slides over the rotary switch, the sliding cover abuts against or separates from the position limiting portion. When the sliding cover abuts against the position limiting portion, the sliding cover cannot be rotated, and therefore the rotary switch cannot rotate either. When the sliding cover separates from the position limiting portion, the sliding cover and the rotary switch can rotate together.

[0008] In one embodiment, a notch is provided at the lower end of the rotary switch, and the rotary switch can be attached to / detached from the pulling part at the position of the notch; when the sliding cover is slid over the rotary switch, the sliding cover covers or exposes the notch, thereby restricting movement between the rotary switch and the pulling part; when the sliding cover is slid until the notch is exposed, the rotary switch and the sliding cover can be attached to / detached from the pulling part together; and when the sliding cover is slid until the notch is covered, the rotary switch and the sliding cover cannot be attached to / detached from the pulling part together.

[0009] In one embodiment, a positioning buckle is provided between the sliding cover and the rotary switch for snapping and positioning the sliding cover and the rotary switch.

[0010] In one embodiment, the positioning buckle has a positioning groove provided on a side of the rotary switch, and a positioning protrusion is provided on a side of the sliding cover, and the positioning protrusion of the sliding cover snaps into the positioning groove during sliding of the sliding cover.

[0012] In one embodiment, the elastic seal has an N-layer structure, and when the container and the container lid are hermetically coupled, the sealing portion formed by the elastic seal has an N-layer structure.

[0013] In one embodiment, the elastic seal is fixedly or removably connected to the movable base or lid body.

[0016] In one embodiment, a pressure plate is provided on the underside of the lid body, and when the movable base moves upward, the underside of the pressure plate abuts against the upper side of the elastic seal, and the lower side of the elastic seal abuts against the upper side of the movable base, thereby deforming the elastic seal, and the edge of the elastic seal extends outside the movable base.When the lower end of the elastic seal is separated from the movable base, the elastic seal recovers from deformation due to the action of the elastic seal itself, and the sealed state is released.

[0017] In the above-mentioned sealed container, after the sliding cover is slid out from the rotary switch, the sliding cover can be rotated at this time, and the rotary switch also rotates synchronously, and the movable base is moved up and down, so that when the lid is opened or closed, the sliding cover lengthens the rotation arm length of the rotary switch, forming a labor-saving lever, making it more convenient and easy to open and close the container. In the case of a container having a larger pressure and a large diameter, the formation of the labor-saving lever makes it more convenient to open and close the container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] In order to make the above objects, features and advantages of the present disclosure more clear and understandable, specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are described in order to fully understand the present disclosure. However, the present disclosure is not limited by the specific embodiments disclosed below, since the present disclosure can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the content of the present disclosure.

[0020] It should be explained that when a component is considered to be "fixed" to another component, it may be directly fixed to the other component, or there may be intermediate components at the same time. When a component is considered to be "connected" to another component, it may be directly connected to the other component, or there may be intermediate components at the same time. Conversely, when a component is said to be "directly" on another component, there are no intermediate components. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used in this disclosure have the same meaning as commonly understood by those skilled in the art. The terms used herein are only for the purpose of describing the embodiments and are not intended to limit the disclosure. The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0022] As shown in FIG. 2 to FIG. 9, the sealed container includes a container 1 and a container lid 2. The container lid 2 includes a lid body 21. A movable base 3 that can move up and down is provided below the lid body 21. An elastic seal 4 is provided between the movable base 3 and the lid body 21. The elastic seal 4 is connected to the lid body 21 or the movable base 3. When the movable base 3 moves upward, the outer edge of the elastic seal is deformed outwardly by the action of the movable base and / or the lid body so as to become larger than the diameter of the sealing part of the container, thereby preventing the movable base from continuing to move upward, and the movable base presses the elastic seal against the inner neck of the container to form a sealing part, thereby realizing the sealing of the container lid and the container. An opening and closing mechanism for opening and closing the container lid 2 is provided on the upper side of the container lid 2. The opening and closing mechanism includes a rotary switch 6 and a sliding cover 7. When the rotary switch 6 is turned, the movable base 3 is moved up and down. The sliding cover 7 is slidably connected to the outside of the rotary switch 6. By sliding the sliding cover 7 out from the rotary switch 6, the length of the rotary switch 6 can be increased.

[0023] After the sliding cover 7 is slid out of the rotary switch 6, the sliding cover 7 can be rotated at this time, and the rotary switch 6 is also rotated synchronously, so that the movable base 3 is moved up and down by the force of the lever, and when the lid is opened or closed, the arm length of the rotary switch 6 is lengthened by the sliding cover 7, forming a labor-saving lever. Therefore, the opening and closing of the container 1 becomes more convenient and easy, and in the case of a container with a larger pressure and a larger diameter, the labor-saving lever makes it more convenient to open and close the container.

[0024] In this case, in the present embodiment, the upper side of the movable base 3 is provided with a tension part 31 that penetrates the container lid 2 and extends to the upper side of the container lid 2. The rotary switch 6 is rotatably connected to the tension part 31. Rotation grooves are provided on both sides of the tension part. The rotary switch is movably connected to the tension part at the position of the rotation groove, and the rotary switch can be stably connected to the tension part by the action of the rotation groove of the tension part and the elastic force of the elastic seal. Specifically, as shown in Figures 8 and 9, a rotation pin is provided on both sides of the rotary switch 6, and a rotation groove is provided on the corresponding side of the tension part 31. In this case, the distance from the rotation pin to both sides of the rotary switch 6 is different. Since the lid body 21 does not move during the rotation of the rotary switch 6, the height of the position of the rotation pin of the rotary switch 6 on the lid body 21 changes during the rotation of the rotary switch 6, and the tension part 31 also changes in height, which is manifested as the up and down movement of the movable base 3. At this time, since the groove mouth of the rotary groove is located at the front part of the cover body (i.e., the side where the rotary switch and the sliding cover are pressed down), when connecting the rotary switch to the pulling part, it is necessary to snap the rotary switch into the inside of the rotary groove along the groove mouth of the rotary groove (push the rotary switch inward so that it snaps from the groove position of the rotary groove to the pulling part). When it is necessary to remove the rotary switch, the rotary switch can be pulled outward along the groove mouth of the rotary groove (the sliding cover slides out and does not interfere with the movement of the rotary switch) and the rotary switch can be removed. Meanwhile, the rotary switch and the pulling part are firmly connected by the action of the rotary groove of the pulling part and the elastic force of the elastic seal.

[0025] As shown in FIG. 2 and FIG. 5, in order to prevent the rotary switch 6 from being opened accidentally during use, in this embodiment, a safety structure for preventing accidental opening is provided. Specifically, a position limiting portion 22 is provided on the upper side of the container lid 2, and when the sliding cover 7 is slid onto the rotary switch 6, the sliding cover 7 abuts against the position limiting portion 22, and the sliding cover 7 cannot be rotated. When the sliding cover 7 is slid out from the rotary switch 6, the sliding cover 7 moves away from the position limiting portion 22, and the sliding cover 7 can be rotated. At this time, the position limiting portion 22 is lower than the upper surface of the container lid 2, and when the sliding cover 7 is slid out onto the rotary switch 6, a part of the sliding cover 7 abuts against the position limiting portion 22, so that the sliding cover 7 cannot be rotated and the rotary switch 6 cannot be rotated either. In this case, it is possible to avoid the rotary switch 6 being opened accidentally and the liquid / object in the container 1 leaking. When it is necessary to open the container lid 2, the sliding cover 7 is partially slid out and separated from the position limiting portion 22 to allow the sliding cover 7 and the rotary switch 6 to rotate, and then the container lid 2 is opened. In this manner, by providing the position limiting portion 22, an opening / closing safety portion for the container lid 2 is formed, and safety during use can be improved.

[0026] As shown in Figs. 8 and 9, in order to prevent the rotary switch 6 from being removed from the position of the pulling part 31, a removal safety structure is provided in this embodiment. Specifically, a notch is provided on one side of the rotary switch 6, and the rotary switch 6 can be attached to / removed from the pulling part 31 at the position of the notch 62. When the sliding cover 7 slides on the outside of the rotary switch 6, the sliding cover 7 covers the notch 62 or exposes the notch 62, so that the sliding cover 7 becomes a removal safety part at the position of the notch 62, thereby restricting the movement between the rotary switch 6 and the pulling part 31. When the sliding cover 7 covers the position of the notch 62, even if an attempt is made to move the rotary switch 6, the sliding cover 7 abuts against the pulling part 31 and is restricted, so that the rotary switch 6 cannot be moved. At this time, the sliding cover 7 has a removal safety function, and it is possible to prevent the rotary switch 6 from being removed unexpectedly. When the sliding cover 7 is moved again to expose the position of the notch 62 from the sliding cover 7, the rotary switch 6 can be removed from the pulling part 31 at the position of the notch 62. In this manner, the rotary switch 6 (together with the sliding cover 7) can be easily removed and washed. Thus, a rotary switch (and sliding cover) removal safety part is formed via the notch 62, which prevents the rotary switch (and sliding cover) from being removed accidentally and improves safety during use.

[0027] In the process of relative movement between the sliding part and the rotary switch 6, when the sliding cover 7 slides into the rotary switch 6 and slides out from the rotary switch 6, a positioning buckle is provided between the sliding cover 7 and the rotary switch 6 to snap and position the sliding cover 7 and the rotary switch 6. Furthermore, the positioning buckle has a positioning groove 61 provided on the side of the rotary switch, and a positioning protrusion 71 is provided on the side of the sliding cover 7, and the positioning protrusion of the sliding cover 7 is snapped into the positioning groove 61 during the sliding of the sliding cover 7. In this case, in order to keep the sliding cover 7 in a relatively constant position during the movement, two sets of positioning grooves are provided, and a certain interval is provided between the two sets of positioning grooves, so that when the sliding cover is moved, the positioning protrusions on the side of the sliding cover can be snapped into different positioning grooves, and the position of the sliding cover 7 during the sliding on the rotary switch 6 is fixed. At this time, for the user, sliding into different positioning grooves represents different states. Of course, it is also possible to set one or more positioning grooves (or positioning buckles) according to actual needs. At the same time, in order to avoid separation of the sliding cover 7 from the rotating switch 6 when the sliding cover 7 is slid out, in this case, a positioning limiting protrusion 72 is provided on the inside of the sliding cover 7. When the sliding cover 7 is slid out to the maximum position, the positioning limiting protrusion 72 abuts against the rotating switch 6, and the rotating switch 6 limits the sliding cover 7 to prevent the sliding cover 7 from continuing to slide and coming off the rotating switch 6.

[0028] When the sliding cover 7 slides on the outside of the rotary switch 6, there are at least three different states between the sliding cover and the rotary switch due to the different relative positions of the sliding cover and the rotary switch. In the first state, the sliding cover 7 abuts against the position limiting portion 22 of the container lid 2, and the container lid 2 and the container are in a sealed state. At this time, the position limiting action of the position limiting portion 22 prevents the sliding cover 7 and the rotary switch 6 from rotating. The sliding cover 7 is partially slid out, and at this time the sliding cover 7 is separated from the position limiting portion 22, allowing the sliding cover 7 to rotate (the rotary switch 6 rotates together), that is, the second state. When the sliding cover 7 is rotated, the rotary switch 6 is also rotated, thereby opening the container lid 2 and the container. At this time, since only a part of the sliding cover 7 is slid out, the other part still partially covers the notch 62 position of the rotary switch 6. In this way, due to the position limiting action of the sliding cover 7, the rotary switch 6 and the sliding cover 7 cannot be separated from the pulling portion 31. The sliding cover 7 continues to slide outward, and while sliding the sliding cover 7, the notch 62 of the rotary switch 6 is fully exposed, that is, the third state is reached. At this time, the rotary switch 6 can be separated from the pulling part 31, and the rotary switch 6 and the sliding cover 7 can be removed simultaneously. In the above three states, the positioning can be performed by setting three positioning buckles, or only one of the farthest stroke switches (for example, the above position limiting protrusions can be used to prevent the sliding cover 7 from coming off the rotary switch 6), and the settings can be made according to actual needs.

[0029] As shown in Figs. 5 to 8, in order to maintain the pressure balance between the inside and outside of the container during use, the present embodiment provides an exhaust hole 32 on the movable base 3. The exhaust hole 32 extends through the tensioning portion 31 to the upper side of the lid body 21. An elastic seal plug 8 is provided above the exhaust hole 32, and a sealing hole 81 communicating with the exhaust hole 32 is provided at the center of the elastic seal plug 8. When the rotary switch 6 is opened or closed, the inside of the sliding cover 6 contacts or separates from the elastic seal plug 8, and during use, the container communicates with or is sealed from the outside through the exhaust hole and the sealing hole. In this way, the pressure balance between the inside and outside of the container can be maintained during opening and closing of the container, and the difficulty of opening and closing the container lid can be reduced.

[0030] During use of the above-mentioned sealed container, the elastic seal 4 is located between the movable base 3 and the lid body 21, and when the movable base 3 moves upward, the outer edge of the elastic seal 4 is deformed outward under the action of the movable base 3 and / or the lid body 21, so that the elastic seal 4 forms a sealing part 41 between the movable base 3 and the container 1 for sealing the container lid 2 and the container 1. Since the overall structure of the elastic seal 4 is simple and the installation and removal are quick and convenient, it can effectively reduce the manufacturing cost and improve the production efficiency.

[0031] In this case, when sealing is performed, the elastic seal 4 only extends to the outside of the movable base 3 and does not bend. Specifically, in this embodiment, the elastic seal 4 has an N-layer structure, and when the container 1 and the container lid 2 are sealed and coupled, the sealing part 41 formed by the elastic seal 4 has an N-layer structure. Here, N is a natural number other than 0, and when the elastic seal 4 has a one-layer (single-layer) structure, the elastic seal 4 has a single-layer structure in a non-sealed state. When sealing, the elastic seal 4 does not bend and maintains the single-layer structure. When the elastic seal 4 has a two-layer (double-layer) structure, the sub-elastic seals of each layer are fixed to each other (or are not fixed. If they are not fixed, a fixed connection position is provided between the sub-elastic seals 4 to avoid relative movement during use and adversely affecting the sealing effect). In this way, sealing can still be formed during use. When the elastic seal 4 has a multi-layer structure, it has the same structure, and the sub-elastic seals are fixed to each other and no positional deviation occurs. In this embodiment, the elastic seal 4 has a single-layer structure, the overall structure is simple, and the sealing performance is good during use.

[0032] Regarding the installation of the elastic seal 4, the elastic seal 4 is fixedly connected or detachably connected to the movable base 3 or the cover body 21. In this embodiment, the elastic seal 4 is installed with a detachable connection, and the installation is performed in a detachable manner, which can facilitate installation and removal, and at the same time, it is more convenient when cleaning is required.

[0033] The elastic seal may be attached to the movable base 3 or to the underside of the lid body 21, but may be located between the movable base 3 and the lid body 21. When sealing, the movable base 3 moves upward so that the gap between the movable base 3 and the container 1 is sealed by the deformed elastic seal 4.

[0034] As shown in Figures 3, 4 and 5, in the first embodiment of the elastic seal 4, specifically, the elastic seal 4 has an annular structure, the upper end of the elastic seal 4 is connected to the lid body 21, and the lower end is located above the movable base 3. When the movable base 3 moves upward, the elastic seal extrudes the maximum diameter of the deformed part of the elastic seal to the outside of the movable base, and the maximum diameter of the extruded elastic seal is larger than the diameter of the sealing part of the container, preventing the movable base from continuing to move upward. The movable base presses the elastic seal against the inner neck of the container to form a sealing part, thereby realizing the sealing between the container lid and the container.

[0035] Here, the lower side of the lid body 21 is provided with a connection part 9 for connecting the elastic seal 4. The connection part 9 is fixed to the lower side of the lid body 21, and a suitable annular groove is provided on the upper side of the elastic seal 4, and the elastic seal 4 is snapped into the annular groove to connect. In this way, the elastic seal 4 can be arranged between the lid body 21 and the movable base 3, and at this time, the connection between the elastic seal and the lid body 21 is indirect. Of course, the integral connection part 9 may be provided on the lower side of the lid body 21, or the elastic seal is connected and the elastic seal is directly connected. In this case, a curved part is provided on the elastic seal 4 so that the elastic seal 4 can be deformed quickly when pressed. The diameter of the upper part fixed to the connection part 9 is smaller than the diameter of the lower part at the deformation position. As a result, when the movable base 3 contacts the lower side of the elastic seal 4, the lower side of the elastic seal 4 is easily deformed outward. In addition, the heights of the inner and outer groove walls of the annular groove are also different. Here, the inner side of the annular groove is higher than the outer side, which makes it easier for the elastic seal 4 to deform when it contacts the movable base 3, forming a sealing part 41 and improving the smoothness of sealing.

[0036] Of course, the elastic seal 4 may be connected to the movable base 3, and an extrusion portion that is extruded and deformed is provided on the underside of the lid body 21, so that a sealing effect can also be achieved.

[0037] As shown in Figs. 6 and 7, in the first embodiment of the elastic seal 4, the elastic seal 4 is an annular structure having an opening in the center. A protrusion 42 is provided between the opening and the edge of the elastic seal 4. The elastic seal 4 is connected to the movable base 3 or the lid body 21 through the opening in the center. When the movable base 3 moves upward, the movable base 3 moves toward the lid body 21, and the elastic seal 4 expands outward due to the action of the movable base 3 and the lid body 21, and its edge extends outside the movable base 3, forming a sealing portion 41 between the container 1 and the container lid 2. Here, a protrusion 42 (which may be an upward or downward protrusion, and in this embodiment, an upward protrusion) is provided between the central opening and the edge of the elastic seal. When the movable base moves upward, it moves toward the lid body, and under the action of the movable base and the lid body, the elastic seal expands outward, and the edge of the elastic seal extends outside the movable base so as to become larger than the diameter of the container mouth, preventing the movable base from continuing to move upward, and the movable base presses the elastic seal against the neck of the container to form a sealing portion, thereby realizing a seal between the container lid and the container.

[0038] Here, the elastic seal 4 may be connected to the movable base 3 or the lid main body 21, but in this embodiment, the elastic seal 4 is connected to the movable base 3. An annular groove 33 is provided in the center of the movable base 3, and the elastic seal is fitted into the annular groove 33, thereby detachably connecting the elastic seal to the movable base 3. Of course, the annular groove 33 for connecting the elastic seal may be provided in the center of the lower side of the lid main body 21, so that the elastic seal can be extruded and deformed to form the sealing portion 41 when the movable base 3 is moved upward.

[0039] In the second embodiment of the elastic seal described above, a pressure plate 5 is provided under the lid body 21 in order to allow the elastic seal 4 to deploy more smoothly. When the movable base 3 moves upward, the lower side of the pressure plate 5 abuts against the upper side of the elastic seal 4, and the lower side of the elastic seal 4 abuts against the upper side of the movable base 3, thereby pushing and deforming the elastic seal 4, and the edge of the elastic seal 4 extends to the outside of the movable base 3. In this way, not only can the elastic seal 4 be fully deployed, but the pressure plate 5 and the lid body 21 can be of a separate structure or an integrated structure, but in this embodiment, the pressure plate 5 and the lid body 21 are of a separate structure, which is convenient for manufacturing, removal and installation.

[0040] In the above two embodiments of the elastic seal, when the elastic seal is used, the sliding cover 7 is slid out, then the sliding cover 7 is rotated, and the rotary switch 6 and the sliding cover 7 are rotated together. When the container lid is opened, the deformed elastic seal needs to return to its original shape, and a force acting on the movable base is generated. In this way, the elastic seal returns to its original shape under the action of the elastic seal, and finally the sealed state is released, and the container lid can be opened.

[0041] In the above two embodiments of the elastic seal, at least one of the contact surfaces between the movable base 3 and the elastic seal 4 is made into an arcuate surface in order to smooth the elastic seal 4 when it deforms. By making the contact surface into an arcuate surface, friction during deformation can be reduced. Furthermore, the shape change of the elastic seal is smoothed, and since the upper outer edge of the movable base 3 and the lower inner edge of the elastic seal 4 are made into arcuate surfaces, deformation of the elastic seal 4 becomes smoother.

[0042] The technical features of the above-described embodiments may be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but as long as there is no contradiction in the combinations of these technical features, they should be considered to be within the scope of this description.

[0043] The above embodiments merely represent some embodiments of the present disclosure, and the description is relatively specific and detailed, but cannot be understood as limiting the patent scope of the present invention. It should be noted that those skilled in the art can make many modifications and improvements without departing from the concept of the present invention, which are within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims. [Explanation of symbols]
