Description

Technical Field

[0001] This invention relates to the field of container lids and containers, and in particular to a press-type threadless container lid and container. Background Technology

[0002] Most water cups on the market are connected to the cup body by threads. A sealing ring is set on the inside of the cup lid. After the cup lid and the cup body are tightened by the threads, the cup body compresses the sealing ring to achieve a seal. When filling with liquid or cleaning, the cup lid must be unscrewed with both hands, which is inconvenient for some special groups who can only operate with one hand. At the same time, due to factors such as thermal expansion and contraction and slipping, it is also inconvenient for the elderly, children and the frail to unscrew the cup lid. Summary of the Invention

[0003] Therefore, it is necessary to provide a push-button screwless container lid and container to address the problems in the existing technology.

[0004] A push-button, threadless container cap, the container cap comprising: The outer shell has a storage space in the middle. The top cover, located on the upper side of the central accommodating space of the outer shell, moves up and down within the central accommodating space of the outer shell. The plug is located below the upper cover and moves up and down synchronously with the upper cover. A soft rubber sleeve is located on the lower side of the central accommodating space of the outer shell and is connected to the outer shell. When the plug moves down, the soft rubber sleeve deforms in all directions to form a sealing part.

[0005] In one embodiment, the soft rubber sleeve includes a fixing part that is connected to the outer shell; An annular portion is located below the fixed portion, and a gap is provided between the outer wall of the annular portion and the inner wall of the outer shell. The plug is located inside the annular portion. The sealing part is located at the bottom of the annular part. When the plug moves downward and acts on the sealing part, the sealing part deforms radially to form a sealing part.

[0006] In one embodiment, the bottom of the annular portion extends toward the axis of the annular portion to form a sealing portion.

[0007] In one embodiment, the sealing portion covers the lower side of the annular portion, and the sealing portion has a protrusion in the middle.

[0008] In one embodiment, the container cap further includes a locking structure, wherein when the plug is moved to a position where the soft rubber sleeve forms a seal, the cap and / or plug is secured to the outer casing by the locking structure.

[0009] In one embodiment, the locking structure includes an inner button on the side wall of the upper cover, an outer hole on the side wall of the outer shell, an outer button at the position of the outer hole on the side wall of the outer shell, and a locking spring on the inner button. When the upper cover moves down to the point where the inner button is aligned with the outer hole, the inner button is engaged in the outer hole under the action of the locking spring, thereby locking and fixing the upper cover and the outer shell.

[0010] In one embodiment, the external button has a hole, and the external button is connected to the outer hole of the outer shell, the width of the hole being greater than the wall thickness of the outer shell.

[0011] In one embodiment, the container lid further includes an elastic element located between the outer shell and the upper cover / stopper, the elastic element being compressed when the upper cover / stopper moves downward.

[0012] In one embodiment, the inner wall of the housing is provided with an annular boss, the annular boss has a connecting hole in the middle for the plug to pass through, and the elastic element is located above the annular boss.

[0013] The aforementioned push-button threadless container cap works by moving the upper cap / stopper downwards, causing the stopper to act on a soft rubber sleeve. Under the action of the stopper, the bottom edge of the soft rubber sleeve deforms outwards, and the deformed soft rubber sleeve comes into contact with the container that needs to be sealed, thus sealing the container and achieving the sealing function of the container cap. When it is necessary to remove the container cap, simply move the upper cap / stopper upwards to restore the soft rubber sleeve to its original position. During operation, simply moving the upper cap / stopper upwards or downwards is enough to seal or release the container cap, making the operation simple and convenient.

[0014] A container employing the aforementioned press-type threadless container cap, wherein the container has a container opening, and the container cap seals the container opening at the container opening position.

[0015] In one embodiment, the container opening is provided with a step, and the sealing part formed by the deformation of the soft rubber sleeve of the container lid abuts against the lower side of the step of the container opening.

[0016] The aforementioned container has a stepped portion that fits the soft rubber sleeve, or it can be a straight-walled structure. During use, the soft rubber sleeve abuts against the inner wall of the container opening to achieve a seal. When using a container with a stepped portion, the soft rubber sleeve abuts against the lower side of the stepped portion to achieve a seal. In this case, the container can be lifted by the lid for easy carrying. When using a straight-walled container, the soft rubber sleeve of the lid deforms outward to achieve a seal with the container.

[0018] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figures 1 to 6 As shown, a push-button type threadless container cap 2 includes: The outer casing 21 has a central receiving space. The upper cover 22 is located on the upper side of the central receiving space of the outer shell 21, and can move up and down within the central receiving space of the outer shell 21. The plug 23 is located below the upper cover 22 and moves up and down synchronously with the upper cover 22. The soft rubber sleeve 24 is located on the lower side of the accommodating space in the middle of the outer shell 21 and is fixed to the outer shell 21. When the plug 23 moves down, the soft rubber sleeve 24 deforms in all directions to form a sealing part.

[0022] By moving the upper cover 22 / stopper 23 downwards, the stopper 23 acts on the soft rubber sleeve 24. Under the action of the stopper 23, the bottom edge of the soft rubber sleeve 24 deforms outwards, and the deformed size is larger than the outer diameter of the original annular part. The deformed soft rubber sleeve 24 abuts against the external container that needs to be sealed, sealing the container and realizing the sealing function of the container lid 2. When it is necessary to remove the container lid 2, simply move the upper cover 22 / stopper 23 upwards to restore the soft rubber sleeve 24 to its original position. During the operation, simply moving the upper cover 22 / stopper 23 upwards or downwards can realize the sealing or unsealing function of the container lid 2, making the operation simple and convenient.

[0023] At this time, in order for the soft rubber sleeve 24 to deform under the action of the plug body 23 and form a sealing part, in this embodiment, the soft rubber sleeve 24 includes a fixing part 241, which is fixed to the outer shell 21; An annular portion 242 is located below the fixed portion 241. A gap is provided between the outer wall of the annular portion 242 and the inner wall of the outer shell 21. The plug 23 is located inside the annular portion 242. The sealing part 243 is located at the bottom of the annular part 242. When the plug 23 moves downward and acts on the sealing part 243, the sealing part 243 deforms radially to form a sealing part.

[0024] The soft rubber sleeve 24 is connected to the outer shell 21 at the fixing part 241. It can be a fixed connection or a detachable connection, so as to prevent the soft rubber sleeve 24 from separating from the outer shell 21 of the cup lid during use. The fixing of the soft rubber sleeve 24 and the outer shell 21 can be done by one-time molding or two-time molding. One-time molding means using two-color injection molding to inject the outer shell 21 and the soft rubber sleeve 24 into the same mold using different materials. This makes the production process faster and more convenient. Of course, the soft rubber sleeve 24 and the outer shell 21 can also be molded separately and then fixed together to simplify the production mold.

[0025] The soft rubber sleeve 24 can be made of various materials, such as silicone or rubber, as long as it has a certain degree of elasticity and deformation ability.

[0026] Meanwhile, the top cover and the plug can be either a separate structure or an integrated structure. When using a separate structure, the two parts do not need to be fixed together, or they can be fixed together by means of clips, glue, or threads. With a separate structure, both parts are easy to manufacture. When using an integrated structure, the number of parts can be reduced, thereby simplifying the assembly process.

[0027] Below the fixing part 241 is the annular part 242. A gap exists between the outer wall of the annular part 242 and the inner wall of the cup lid shell 21. When the cup lid is placed on top of the cup body, the opening of the cup body is located within the gap between the outer side of the annular part 242 and the cup lid. Thus, the annular part 242 is located within the internal space of the cup body. Consequently, the sealing part 243 located below the annular part 242 is also within the internal space of the cup body. After the cup lid is placed on top of the cup body, the sealing part 243 of the soft rubber sleeve 24 of the cup lid is not higher than the step 12 of the cup body. Because the soft rubber sleeve 24 and the cup... With the outer shell 21 fixed, the sealing part 243 of the soft rubber sleeve 24 is fixed relative to the outer shell 21. During the downward movement of the plug 23, the plug 23 acts on the sealing part 243 of the soft rubber sleeve 24, causing the sealing part 243 to bend and deform outward. The sealing part 243, which deforms outward, abuts against the lower side of the cup body step 12, thereby forming a sealing part that seals the cup body and the cup lid together. At this time, in order to form a better sealing effect, the cup body step 12 is an inclined step 12, and the sealing part abuts against the lower side of the inclined step 12, thereby forming a seal between the cup body and the cup lid.

[0028] Furthermore, in order to ensure a good seal between the container cap 2 and the container, the sealing part 243 extends from the bottom of the annular part 242 toward the axis of the annular part 242 in this embodiment. Specifically, the sealing part 243 extends from the bottom of the annular part 242 toward the axis of the annular part, or the sealing part 243 is a protruding part toward the axis of the annular part. In this way, the sealing part 243 is located on the lower side of the annular part 242 to facilitate the integral molding of the soft rubber sleeve 24. At the same time, as the plug body 23 moves downward, the outer wall of the sealing part 243 acts on the inner wall of the annular part 242 and the upper side of the sealing part 243, thereby causing the sealing part 243 to deform outward and form a sealing part. At this time, the outermost end of the sealing part exceeds the original size of the sealing part 243, thus forming a better seal between the container cap 2 and the inner wall of the container.

[0029] Regarding the dimensions of the sealing part, in order to achieve a better sealing effect, the inner diameter of the sealing part gradually decreases from top to bottom. When the inner diameter is smaller than the diameter of the plug body, the plug body will create resistance after moving downward and contacting the sealing part. The plug body will exert an outward or downward pushing force on the flexible and elastic sealing part, causing it to deform and protrude outward and close to the inner side of the container mouth step, thus playing a sealing and locking role. At this time, since the sealing part has a certain thickness, the sealing part that protrudes outward can fit better into the inner side of the container step, thereby forming a better sealing effect.

[0030] To ensure a more stable formation process and prevent abnormalities during the formation of the sealing portion 243 of the soft rubber sleeve 24, in this embodiment, the inner side of the connection between the annular portion 242 and the sealing portion 243 is an inner arc surface 245, and the bottom of the plug body 23 is provided with a rounded corner 246 corresponding to the inner arc surface 245. This ensures that the plug body 23 is completely fitted to the upper side of the sealing portion 243 of the soft rubber sleeve 24, and the fitting area is arc-shaped. This allows the plug body 23 to move completely within the soft rubber sleeve 24 when it moves downwards, and also ensures that the sealing portion 243 of the soft rubber sleeve 24 deforms in a predetermined direction.

[0031] Meanwhile, during the deformation of the sealing part 243, to prevent it from forming a pointed tip and affecting the sealing effect, in this embodiment, the outer side of the connection between the annular part 242 and the sealing part 243 is an arc-shaped chamfer 247 or a beveled chamfer. That is, the outer side of the bottom of the sealing part 243 is an arc-shaped chamfer 247 or a beveled chamfer. Compared with a normal right-angle structure, this results in a larger contact area between the outer side of the sealing part 243 and the inner wall of the container after the sealing part 243 deforms and folds outward. The outer side of the sealing part 243 can better abut against the inner wall of the container, resulting in a better sealing effect.

[0032] At this time, the length of the plug 23 matches the depth of the annular portion 242. That is, during the movement of the plug 23 inside the annular portion 242, when the plug 23 moves to its lowest position, the lower side of the plug 23 abuts against the bottom of the soft rubber sleeve 24, causing the sealing portion 243 to deform and form a sealing ring. Alternatively, the lower side of the plug 23 may extend beyond the lower side of the sealing portion 243, squeezing the entire sealing portion 243 to the outside of the plug 23, so that the sealing portion is located outside the plug 23 and the annular portion 242. In these cases, an opening is provided in the middle of the sealing portion 243 to facilitate the movement of the plug 23 (e.g., Figure 7 (As shown).

[0033] Of course, the sealing part 243 can also be fully sealed or partially sealed. Specifically, in this embodiment, the sealing part 243 covers the lower side of the annular part 242, and the sealing part 243 has a protrusion 244 in the middle. At this time, the sealing part 243 has an upwardly protruding protrusion 244. During the downward movement of the plug 23, the plug 23 first contacts the protrusion 244 of the sealing part 243. After the plug 23 continues to move downward, the lower side of the plug 23 abuts against the upper side of the sealing part 243, thereby pressing the bottom of the seal to deform, thereby forming a seal.

[0034] At this time, the sealing part 243 can be the entire surface or it can be provided with a hollow, neither of which will affect the sealing part 243 forming a sealing part under the action of the plug body 23.

[0035] After the top cover 22 / stopper 23 is moved downwards and the sealing portion 243 of the soft rubber sleeve 24 forms a sealing ring, in order to maintain the deformation of the soft rubber sleeve 24, it is necessary to ensure that the position of the top cover 22 / stopper 23 remains unchanged. Therefore, in this embodiment, the container also includes a locking structure 25. When the stopper 23 moves to the point where the soft rubber sleeve 24 forms a sealing portion, the top cover 22 and / or the stopper 23 are fixed to the outer shell 21 by the locking structure 25. When the top cover 22 moves downwards to a certain position, the soft rubber sleeve 24 deforms outwards to form a sealing portion, sealing the cup body and the cup lid. In order to maintain the sealing effect, it is necessary to fix the cup body and the cup lid together, hence the locking structure 25 is provided.

[0036] Specifically, the locking structure 25 includes an inner button 251 on the side wall of the upper cover 22, an outer hole on the side wall of the outer shell 21, and an outer button 252 located at the outer hole. The inner button 251 is equipped with a locking spring 253. When the upper cover 22 moves down until the inner button 251 aligns with the outer hole, the inner button 251 is engaged in the outer hole under the action of the locking spring 253, thereby securing the upper cover 22 and the outer shell 21. Under the action of the locking spring 253, the inner button 251 moves outward. Due to the restriction of the outer shell 21, the inner button 251 cannot move out until it aligns with the outer hole of the outer shell 21. In this way, the inner button 251 is engaged in the outer hole under the action of the locking spring 253, abutting against the inner side of the outer button 252, thereby fixing the upper cover 22 and the outer shell 21 together.

[0037] When it is necessary to open the cup lid, that is, to remove the inner button 251 from the outer hole of the outer shell 21, in this embodiment, the outer button 252 is provided with a hole 211, and the outer button 252 is connected to the outer hole of the outer shell 21 at the hole 211. At this time, since the width of the hole 211 of the outer button 252 is greater than the wall thickness of the outer shell 21, the outer button 252 can move at the outer hole position of the outer shell 21. After the inner button 251 is inserted into the outer shell 21 at the outer hole position, the outer button 252 is pushed and the outer side of the outer button 252 protrudes from the outer wall of the outer shell 21. At this time, the outer button 252 is pressed on the outside of the outer shell 21, and the outer button 252 acts on the inner button 251. The locking spring 253 of the inner button 251 is compressed, and the inner button 251 retracts from the outer hole position of the outer shell 21. In this way, the locking structure 25 between the upper cover 22 and the outer shell 21 is opened, and relative movement can occur between the two. As a result, the upper cover 22 and the plug 23 can move. When the plug 23 moves upward, the soft rubber sleeve 24 returns to its original shape, and the cup lid and the cup body can be separated.

[0038] When the upper cover 22 and the outer shell 21 are not locked together by the locking structure 25, the deformed soft rubber sleeve 24 acts on the stopper 23 when it recovers its deformation, allowing the stopper 23 to move upward, which in turn causes the upper cover 22 to move upward, thus opening the cup lid. In this embodiment, to enable the upper cover 22 to move upward quickly, the container also includes an elastic element 26 located between the outer shell 21 and the upper cover 22 / stopper 23. When the upper cover 22 / stopper 23 moves downward, the elastic element 26 is compressed. During the downward movement of the upper cover 22 / stopper 23, the elastic element 26 is compressed until the upper cover 22 and the outer shell 21 are locked together by the locking structure 25. After the locking structure 25 between the upper cover 22 and the outer shell 21 is opened, the upper cover 22 can move upward quickly under the action of the elastic element 26, causing the stopper 23 to also move upward, opening the cup lid and the cup body.

[0039] To prevent the elastic element 26 from affecting the movement of the stopper 23 / top cover 22 during compression and recovery deformation, in this embodiment, the inner wall of the outer shell 21 is provided with an annular boss, and the annular boss has a connecting hole in the middle for the stopper 23 to pass through. The elastic element 26 is located above the annular boss. In this way, the elastic element 26 is positioned between the outer shell 21 and the stopper 23, and will not affect the up-and-down movement of the cup lid.

[0040] At this time, since there is relative movement between the upper cover 22 and the outer shell 21, in order to prevent the upper cover 22 from detaching from the outer shell 21 during the movement, in this embodiment, a limiting structure 27 is provided between the upper cover 22 and the outer shell 21. Specifically, the limiting structure 27 includes a limiting groove 271 on the inner side of the outer shell 21 and a limiting protrusion 272 on the outer side of the upper cover 22. Two or three limiting grooves 271 and limiting protrusions 272 are provided (of course, other numbers are also possible, as long as they can keep the upper cover 22 from detaching from the outer shell 21). (The cover 22 and the outer shell 21 can be fixed together). The lower side of the limiting protrusion 272 is provided with an inclined surface and an arc surface. After the plug 23, silicone ring and locking structure 25 are installed, the upper cover 22 is pressed into the middle of the outer shell 21 from the upper side, thereby connecting the upper cover 22 and the outer shell 21. During subsequent use, when the upper cover 22 moves up and down, due to the limiting effect of the limiting protrusion 272 and the limiting groove 271, the upper cover 22 will not detach from the outer shell 21, thereby ensuring that the upper cover 22 can be used normally.

[0041] A container using the aforementioned press-type threadless container cap 2, wherein the container 1 is provided with a container opening 11, and the container cap 2 seals the container opening 11 at the container opening 11 position.

[0042] In order to more firmly fix the container 1 and the container lid 2, in this embodiment, the container opening 11 is provided with a step 12, and the sealing part formed by the deformation of the soft rubber sleeve 24 of the container lid 2 abuts against the lower side of the step 12 of the container opening 11. The container is provided with a step 12 that fits the soft rubber sleeve 24, or it can be a straight wall structure. During use, the soft rubber sleeve 24 abuts against the inner wall of the container opening 11 to achieve a seal. When using a container with a step 12, the soft rubber sleeve 24 abuts against the lower side of the step 12 of the container to achieve a seal. At this time, the container can be lifted by the container lid 2 for easy carrying. When using a straight wall container, the soft rubber sleeve 24 of the container lid 2 deforms outward to achieve a seal with the container.

[0043] For step 12 of the container at this time, that is, the inner diameter of the container opening is smaller than the inner diameter of the container interior, a connection will be formed between the container opening and the container interior. The step is set at the connection position. At this time, the step is set at an angle, and the angle formed between the inner side of the container opening and the outer side of the step is greater than 180° and less than 360°. Figure 5 (C) In this way, the sealing part formed by the soft rubber sleeve abuts against the inclined lower side of the step, thereby forming a seal.

[0044] When the container has a step 12, the container can be a cup body, thus forming a thermos cup with a good sealing effect. When the container is a straight-walled container, that is, the container opening is a straight wall, without a step 12, or without size changes, such as the opening of a cosmetic bottle or wine bottle, the container lid 2 can be used to separate the inside of the container from the outside, thus forming a seal. Although the container cannot be lifted through the container lid 2, it still has a good sealing effect.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
