Airtight cover

Abstract

An airtight cover for a container having an opening includes a cover body and a sliding member. The cover body detachably covers the opening to assemble to the container. A mounting portion is arranged on a side of the cover body. The sliding member is slidably connected to the mounting portion, has a slope, and is configured to move along a surface of the mounting portion between a first position and a second position. The slope is slidably abutted against to an edge of the opening when the sliding member moves from the first position to the second position due to force, and the slope gradually separates from the container with the cover body during the sliding process. The airtight cover is therefore simple in structure, low in failure, and low in cost.

Description

[Technical Field]

[0001] This application relates to the lid of an airtight container, and in particular to an airtight lid that is simple in structure and can reduce costs. [Previous Technology]

[0002] Regarding sealed containers, the sealing cap is usually fitted to the opening of the container. After the sealing cap is fitted, it is in a sealed state and can be released by turning it to open the sealing cap.

[0003] Conventional sealing caps have a relatively complex structure, which must include an inner cap, an outer cap, a sealing gasket, a linkage seat, a lever, and an elastic element. The inner cap and outer cap are arranged one inside the other and one above the other. The sealing gasket is fitted onto the inner cap. The linkage seat is inserted into the outer cap and fixed to the inner cap at the insertion end. The lever is rotatably connected to the linkage seat and abuts against the top surface of the outer cap. Thus, by moving the lever, the linkage seat can cause the inner cap to move downward relative to the outer cap to open the seal, and the linkage seat can also cause the inner cap to move upward relative to the outer cap to force the sealing gasket to abut against the tank body to seal, and the mechanism can switch between opening and sealing.

[0004] Although conventional sealing caps can meet the basic requirements of sealing and opening, they have many parts and a relatively complex structure, resulting in higher costs and making them less competitive in the market. Moreover, the complex structure is prone to failure and damage, which has long been criticized.

[0005] Therefore, how to improve the shortcomings of the aforementioned prior art is a major issue that the creator of this application urgently wants to solve. [Summary of the Invention]

[0006] The purpose of this application is to provide an airtight cover with a relatively simple structure and reduced cost.

[0007] To achieve the above objective, this application provides an airtight cap for a container with an opening. The airtight cap includes: a cap body that detachably covers the opening and is combined with the container, at least one side of the cap body having a mounting portion; and at least one sliding member that slides onto the mounting portion and has an inclined surface, the sliding member being movable along the surface of the mounting portion between a first position and a second position; wherein, when the sliding member moves from the first position to the second position by force, the inclined surface slidably abuts against the edge of the opening, and the inclined surface gradually detaches the cap body from the container during the sliding displacement process.

[0008] Compared with the prior art, this application has the following advantages: because the structure of the airtight cover is simpler (e.g., fewer parts), it has the effect of low failure rate and reduced cost, and thus has a better competitive advantage in the market.

Implementation Method

[0009] The detailed description and technical content of this application are illustrated below with reference to the accompanying drawings. However, the accompanying drawings are provided for reference and illustration only and are not intended to limit this application.

[0010] This application provides an airtight cover. Figures 1 to 6 show the first embodiment of this application, and Figure 7 shows the second embodiment of this application.

[0011] As shown in Figures 1 to 4, in the first embodiment, an airtight cover 100 and a container 800 are combined to form an airtight container device.

[0012] The container 800 includes a surrounding wall (not indicated by component symbol), one end of the surrounding wall is closed, and the other end forms an opening 8. The surrounding wall has an edge 81 corresponding to the opening 8, and the edge 81 surrounds the opening 8.

[0013] The airtight cover 100 includes a cover body 1 and at least one sliding member 2, and preferably also includes a sealing ring 3. This application does not limit the number of sliding members 2, but one is used as an example in this embodiment. It should be noted that even without the sealing ring 3, the airtight cover 100 can achieve an airtight effect by utilizing the dimensional fit between the airtight cover 100 and the container 800.

[0014] The cover 1 can be detachably fitted onto the container 800 corresponding to the opening 8. After the cover 1 is closed, it is in the closed state as shown in Figure 3. In addition, the cover 1 may have one side (e.g., a circular cover not shown in the figure) or multiple sides (e.g., a rectangular cover 1 shown in Figure 1). In this embodiment, it is described as having multiple sides, and a mounting part 12 is provided on one of the sides 17 of the cover 1.

[0015] The mounting part 12 can be any structure that can mount the sliding member 2. In this embodiment, the mounting part 12 is described as a recessed groove 121. In detail, the cover 1 has a cover surface 11, and the recessed groove 121 is recessed from the cover surface 11. The recessed groove 121 has an outer side surface 1211 (or surface) at the bottom of the groove, and a plurality of groove sidewalls 1213 connected to each other are formed around the recessed groove 121. Each groove sidewall 1213 surrounds the periphery connected to the outer side surface 1211 and has a notch 1214 at the corresponding side 17.

[0016] The sealing ring 3 is disposed around the cover body 1. Specifically, the bottom of the cover body 1 has a fitting periphery 13, and the fitting periphery 13 has an annular groove 131. The sealing ring 3 has its inner ring portion embedded in the annular groove 131, and its outer ring portion exposed outside the annular groove 131 to form an exposed portion 31. As shown in Figure 3, when the cover body 1 is in the closed state, the exposed portion 31 of the sealing ring 3 will be deformed by being clamped (or squeezed) between the outer periphery of the cover body 1 and the inner peripheral wall of the container 800.

[0017] The sliding member 2 is slidably mounted within the mounting portion 12. Before sliding, the sliding member 2 does not protrude from the mounting portion 12 (see Figure 3). After sliding, a portion of it protrudes from the mounting portion 12 via the notch 1214 (see Figure 6). In other words, the sliding member 2 can move along the outer surface 1211 between a first position and a second position (neither of which is indicated by component symbols) of the mounting portion 12. The portion of the sliding member 2 that protrudes from the mounting portion 12 after sliding also forms an inclined surface 23. The inclined surface 23 can be a plane (not shown in the figure) or an arcuate convex surface as shown in Figure 3. This application does not limit this, but in this embodiment, an arcuate convex surface is used as an example for explanation.

[0018] As shown in Figures 3 and 4, when the airtight cover 100 is closed on the container 800 at the position corresponding to the opening 8, the exposed part 31 of the sealing ring 3 will be squeezed (as mentioned above) and together with the cover 1 will seal the opening 8. At this time, the airtight container device is in an airtight state, which forms a certain airtight pressure inside it, and the sliding member 2 can slide against the edge 81 of the opening 8.

[0019] As shown in Figures 5 and 6, when the user wants to open the airtight cover 100, he / she only needs to slide the sliding member 2 from the first position to the second position. During the sliding movement, the inclined surface 23 will gradually lift up one side along with the side 17 of the cover body 1. That is, the sliding member 2 will gradually push the edge 81 back with its inclined surface 23 and thereby allow the airtight cover 100 to be separated from the container 800. At this time, the cover body 1 is in the lifted state (component symbols are not marked).

[0020] It should be noted that, as shown in Figures 2 and 3, the inclined surface 23 has a closing corresponding portion 231 and a raised corresponding portion 232 that are spaced apart from each other. When the sliding member 2 is in the first position, the closing corresponding portion 231 is adjacent to the aforementioned edge 81 as shown in Figure 3. When the sliding member 2 is in the second position, the raised corresponding portion 232 will abut against the edge 81. Therefore, in the closed state, the distance from the position where the exposed portion 31 abuts against the container 800 to the edge 81 is approximately equal to (or less than) the distance in the height direction between the closing corresponding portion 231 and the raised corresponding portion 232. In this way, as shown in Figure 6, when the cover 1 is in a tilted-up state with one side raised, the part of the exposed portion 31 corresponding to the side 17 (hereinafter referred to as the corresponding part of the exposed portion 31) will rise from a height position that is originally far away from the edge 81 (see Figure 3) to another height position that is close to the edge 81 (see Figure 6), so that the corresponding part of the exposed portion 31 and the inner peripheral wall of the container 800 can be squeezed together and a gap can be created. The outside air can then enter the airtight container device through this gap and depressurize (release the aforementioned airtight pressure), thereby releasing the original airtight state. After the airtight state is released, the airtight cover 100 can be easily opened because the pressure has been released.

[0021] Therefore, the structure of the airtight cover 100 of this application is relatively simple (one reason being that there are fewer parts), resulting in a low failure rate and reduced costs, thus giving it a better competitive advantage in the market. Moreover, the airtight cover 100 of this application can use the existing container 800 without requiring further structural modifications to the container 800.

[0022] Preferably, in order to achieve faster depressurization and open the airtight cover 100 with less effort, as shown in Figures 1 to 6, a depressurization structure 16 can be provided in the mounting part 12. The depressurization structure 16 has a depressurization hole 1621 communicating with the container 800. When the sliding member 2 is in the first position, the depressurization hole 1621 can be sealed, so that the airtight container device can remain airtight before opening the cover. When the sliding member 2 is in the second position, the depressurization hole 1621 can be exposed, so that the partially exposed depressurization hole 1621 can be used to pre-depressurize. Therefore, as soon as the user completes the sliding operation of the sliding member 2, the airtight cover 100 can be opened, and there is no need to wait for depressurization. Moreover, using the depressurization structure 16 to depressurize allows the user to open the airtight cover 100 without applying too much force.

[0023] The pressure relief structure 16 system includes a through hole 161 and a plug 162. The through hole 161 is formed in the mounting portion 12 and extends between the outer surface 1211 and the container 800. The plug 162 is a soft plug (e.g., made of silicone) and has the aforementioned pressure relief hole 1621. Preferably, the plug 162 also has an outward protrusion 1622, through which the pressure relief hole 1621 passes. When the plug 162 is inserted into the through hole 161, its outward protrusion 1622 will remain outside the through hole 161 and protrude from the outer surface 1211. It should be noted that a groove 122 is formed on the outer surface 1211, and a through hole 161 is disposed in the groove 122. When a part of the plug 162 is disposed in the groove 122 and the other part is inserted into the through hole 161, the protrusion 1622 will protrude out of the outer surface 1211.

[0024] The sliding member 2 has a bottom surface 24. Generally, when the sliding member 2 is in the first position, the sliding member 2 can press the outer protrusion 1622 with its bottom surface 24. Since the outer protrusion 1622 is part of a soft plug (both the cover 1 and the sliding member 2 are hard components), it can seal the pressure relief hole 1621 without causing pressure leakage. Preferably, in order to improve the effect of pressing the outer protrusion 1622 and the effect of opening / closing the pressure relief hole 1621, a bottom protrusion 241 can be protruded from the bottom surface 24 at the position corresponding to the outer protrusion 1622, so that the sliding member 2 can press the outer protrusion 1622 with its bottom protrusion 241 in the first position and seal the pressure relief hole 1621 accordingly. In addition, by adding the bottom protrusion 241, it also has the effect of accurately pressing the outer protrusion 1622 and accurately controlling the opening / closing of the pressure relief hole 1621.

[0025] Furthermore, as shown in Figures 1 to 6, this application does not limit how the sliding member 2 should slide against the mounting portion 12. Generally speaking, a first sliding structure S1 and a second sliding structure S2 that slide against each other can be provided on the mounting portion 12 and the sliding member 2 respectively, so that the sliding member 2 can slide relative to the mounting portion 12.

[0026] Specifically, the first sliding structure S1 includes at least one guide groove 14, and the second sliding structure S2 includes at least one block component 22, which is slidably connected within the guide groove 14, allowing the sliding member 2 to slide according to the guide groove 14. This application does not limit the number of guide grooves 14 and block components 22; in this embodiment, two are used as examples. Both guide grooves 14 are straight grooves and are respectively opened on the opposite sidewalls 1213 of the aforementioned two grooves. The two block components 22 are respectively disposed on two opposite sides of the sliding member 2. As shown in the figure, a sidewall 21 is formed on each of the two opposite sides of the sliding member 2, and the two block components 22 protrude from the two sidewalls 21. Each block component 22 includes a slider 221, which is slidably disposed within the guide groove 14, allowing the slider 221 to move between the two ends of the guide groove 14, and these two ends of the guide groove 14 correspond to a first position and a second position, respectively.

[0027] In order to generate a tactile feel before and after sliding, as shown in Figures 1 to 6, a partition rib 141 protrudes from the guide groove 14, and the block assembly 22 also includes a positioning block 222. The slider 221 and the positioning block 222 are arranged at intervals. When the slider 2 is in the first position, the slider 221 and the positioning block 222 are located on both sides of the partition rib 141 in the guide groove 14. It should be noted that since the positioning block 222 has a convex arc shape, and the partition rib 141 also has a convex arc shape and is opposite to the positioning block 222 (facing each other), when the positioning block 222 slides from the first position to the second position along with the slider 2, the positioning block 222 will cross from one side of the partition rib 141 to the other side of the partition rib 141; as for the slider 221, since it does not have a convex arc shape, it will be blocked by the partition rib 141 and will not be able to cross from the other side of the partition rib 141 to one side of the partition rib 141. Therefore, when a user wants to open the airtight cover 100 and pushes the sliding member 2 to slide, the required tactile feedback is generated as the positioning block 222 passes over the partition rib 141. In addition, the airtight cover 100 can use the partition rib 141 to restrict the positioning block 222, so that the positioning block 222 will not easily shift, thus ensuring that the sliding member 2 will not lose its original airtight state due to accidental sliding to depressurization.

[0028] As shown in Figures 1, 3, and 6, the sliding member 2 has an upper surface 25, with a recess 251 recessed downwards on the upper surface 25. The sliding member 2 also has a hook 252 protruding upwards from the upper surface 25, and the hook 252 is provided corresponding to the inclined surface 23. Therefore, the user can apply force to the sliding member 2 by inserting a finger into the recess 251 and hooking the hook 252 in the opposite direction, so as to pull the sliding member 2 to slide.

[0029] As shown in Figure 7, this is the second embodiment of the present application. The second embodiment is largely the same as the first embodiment described above, except that in the second embodiment, a larger airtight cover 500 is used to cover a larger container 900. The present application does not limit the specific shape of the larger container; in this embodiment, a rectangle is used as an example for illustration, while the first embodiment described above could be a square.

[0030] In the second embodiment, the cover 1 has a plurality of sides, including two sides 17 and 18 that are opposite to each other. The cover 1 is provided with a mounting part 12 corresponding to the two sides 17 and 18, and the two mounting parts 12 are symmetrical to each other. The two sliding members 2 are respectively slidably connected to the two mounting parts 12 and each has an inclined surface 23.

[0031] In this way, the user can pull the two sliding parts 2 to slide, so that the inclined surfaces 23 of the two sliding parts 2 can push the edge of the container 900 in the opposite direction, so that the two sides 17 and 18 of the cover 1 are raised relative to the container 800 to form a double-sided upturn, so that the pressure can be easily released and the airtight cover 500 can be opened.

[0032] In summary, the airtight cover of this application can indeed achieve the expected purpose and effect, and can solve the shortcomings of the prior art. Therefore, this patent application is filed.
