Description

Sealable lid and container containing it [Related Application Case]

This non-provisional patent application claims the provisional patent application No. 62/720,383 filed on August 21, 2018, the disclosure of which is incorporated herein by reference in its entirety.

The present invention relates to the field of container lids. Specifically, the present invention relates to a lid that can form an air- and water-tight seal for a container, such as a food and/or drink container, and preferably a thermally insulated food container. The lid is configured to have a sealing mechanism that can be controlled by a pivoting manual member to provide an unexpectedly simple solution that allows the container to be opened and closed easily.

In a conventional food container equipped with a sealable lid, a sealing member disposed circumferentially around the lower part of the lid can achieve a seal between the lid and the container body. The cover is configured with a movable bottom plate, which is mechanically connected to a button or manual piece on the top of the cover. The operation of the button or manual part causes the bottom plate to move up or down to compress the sealing member. The sealing member is then expanded to press against the inner wall of the container body to produce a seal of the container.

However, this sealing mechanism is opened with the bottom plate moving up and down. Open and close the container. The main defect is that when the container contains high-temperature contents in a closed state, the bottom plate of the lid is caused to move down to its lower position to bias the sealing member against the inner wall of the container body. Thus, the increased internal pressure causes the internal volume of the container to decrease. Therefore, when what is needed is to seal the container in its closed state, a relatively large amount of manpower is required to operate the button or manual part to make the container airtight. Similarly, when what is needed is to open a sealed container, a greater force is required to operate the button or manual part to open or remove the lid from the container. This type of food container makes it difficult for the elderly and children to use a sealable food container.

In order to solve the above-mentioned drawbacks, most of the sealable containers available on the market are provided with a gas valve for balancing the pressure inside and outside the container. On the one hand, the air valve requires more structural components and will affect the sealing performance, especially when storing liquid contents. On the other hand, when the container is designed to be thermally insulated, the valve will also reduce the ability to keep warm.

Accordingly, there is a need for sealable container lids, especially suitable for cooked food and beverage contents, whose lids are easily manufactured at a low price and allow to be opened or closed effortlessly. There is also a need for container lids that can be easily disassembled and reassembled for cleaning purposes.

The present invention has been developed to fulfill the above-mentioned needs, and therefore has the main purpose of providing a container lid which, although simple in structure, produces an air-tight and liquid-tight seal for the container.

Although the present invention is illustrated and described in the preferred embodiment, the container lid and sealing ring can be made in many different configurations, sizes, forms, and materials.

Referring to the drawings, FIGS. 1 to 11 show a cooked food container 1 constructed according to the first preferred embodiment of the present invention. The container 1 (which is substantially in the shape of a cylinder) includes a sealable lid 10 and a container body 20, and the lid is placed above the container body. As shown in FIG. 1, the container is in an airtightly closed state, wherein the container body 20 in the container is well sealed. The container may be of a type that needs to maintain high or low temperature thermal insulation in order to store food, beverages and other items for a period of time.

The sealable cover 10 includes a cover body 11 having a top plate 12; a manual part 13 having a pivotal end 131 and a free end 132, the pivotal end 131 is pivotally mounted on the top plate 12, and the free end 132 can be used to operate the manual part ; Operatively coupled to the top plate 12 of the bottom plate 14; and the movable plate 15 arranged between the top plate 12 and the bottom plate 14. For the purpose of being pivotally mounted on the top plate 12, the manual member 13 is provided with two pivot points 133 on opposite sides of the pivot end 131. As shown in FIG. 2, at the pivoting end 131 of the manual member, the extension 134 between the two pivot points 133 is laterally formed to be operatively adjacent to the movable plate 15 in rotation. The manual member 13 can pivot against the pivot end 131 to seal or unseal the container 1.

Turning to FIGS. 3 to 5, a cover body 11 with a top plate 12 is shown. The cover body has a peripheral portion 111 extending downward from the periphery of the cover body. The peripheral portion 111 is configured and dimensioned to cover the opening of the container body 20, and is formed with internal threads for mating engagement with corresponding threads, which are formed on an outer surface of the container body 20.

As shown, the top plate 12 includes four buckling pieces 121, and the buckling pieces 121 extend circumferentially downward from the lower surface thereof at equal angular intervals. Each of the fastening pieces 121 has a trunk portion 1211 and an outward hook 1212 arranged at one end of the trunk portion 1211. The top plate 12 further includes a receiving chamber 122 in the center of the top plate 12, and the receiving chamber 122 is used for accommodating the manual part 13. The receiving chamber 122 is so configured to allow the manual member 13 to be flush with the top plate 12 when the container 1 is closed, as shown in FIG. 1. The receiving chamber 122 has a passage for allowing the pivoting end 131 of the manual member 13 to pass therethrough to be adjacent to the window 124 against the movable plate, which will be discussed below. The receiving chamber 122 further has two opposite notches 123 on both sides thereof, and the notches 123 respectively carry the two pivot points 133 formed on the pivot end 131 of the manual part 13 by the notches 123 In this way, it is positioned and dimensioned to allow the pivoting movement of the manual member 13 relative to the top plate 12. In this embodiment, the manual member 13 is allowed to pivot relative to the top plate 12 at an angle between 0° and 90°.

Fig. 5 is a cross-sectional view of the top plate 12 taken along the line I-I of Fig. 1. The three buckling pieces 121 can be seen in this cross-sectional view, and the notches 123 for pivotally connecting the contacts 133 of the manual part 13 become more obvious.

The bottom plate 14 is substantially a disc shape in this embodiment, and includes an upper plate portion 141 (made of plastic material or silicon) and a lower plate portion 142 (made of metal material such as stainless steel or aluminum). Generally speaking, the upper plate portion 141 and the lower plate portion 142 are fixed together by an adhesive or other methods known in the art. It is suggested that the metal lower plate portion 142 that directly contacts the high-temperature content in the container 1 provides durability and resistance to the high-temperature content. As can be seen in FIG. 2, the four fastening short pieces 143 are generated on a top surface of the upper plate portion 141, and are positioned to correspond to the fastening pieces 121 in a releasable manner with the fastening pieces 121 buckle. In this embodiment, the buckling short pieces 143 are buckled with the buckling pieces 121 by rotating the bottom plate 14 relative to the top plate 11, so that the bottom plate 14 and the top plate 12 are fixedly buckled for assembly.

One of the features of the present invention is the movable plate 15 shown in FIG. 6, which is arranged in a movable manner between the top plate 12 and the bottom plate 14. The movable plate 15 includes a plate member 151 formed with a protrusion 152 (see FIG. 2). The movable plate 15 further includes a wall 153 extending from the periphery of the plate member 151, and four slots 154 are positioned corresponding to the fastening pieces 121. The wall 153 of the movable plate 15 has a height less than the length of the torso portion 1211 of the fastening piece 121, so that the movable plate is at a first lower position in the airtight closed state of the container in the length direction of the fastening piece ( (See Fig. 10) and a second upper position (See Fig. 11) where the container is in an unsealed state. The fastening pieces 121 of the top plate 12 movably pass through the individual slots 154 to buckle with the fastening pieces 143 of the bottom plate 14. It will be understood that the movable plate 15 is not rotatable relative to the top plate because of the arrangement of the fastening pieces 121.

The protrusion 152 has a substantially flat top surface 1521 and a concave bottom surface 1522. The top surface 1521 is adjacent to the extension piece 134 of the hand piece 13 so that it is affected by the action exerted by the hand piece 13. The concave bottom surface 1522 is configured to snugly receive the anchoring end of a spring member (such as the compression spring 16). As can be seen in Fig. 8, the compression spring 16 is arranged to continuously apply an upward force to the movable plate 15, so that the movable plate 15 moves upward after the pressure applied to the movable plate 15 by the manual member 13 is removed. Movement, which in turn causes the compression spring 16 to be released. The other end of the compression spring 16 is in contact with the upper plate portion 141 of the bottom plate 14. In other words, the pivotal movement of the manual member 13 relative to the top plate 12 can drive the movable plate 15 to move up and down between the first lower position and the second upper position.

Referring now to FIGS. 6 and 7, the neck 155 extends downward and circumferentially from the bottom of the movable plate 15. A flange 156 is formed on an outer surface of the neck 155 to engage with the sealing member 17, which will be discussed below.

The sealing member 17 is provided between the cover body 11 and the bottom plate 14. 9 shows an exemplary structure of the sealing member 17, which includes a first portion 171 having a groove 173 (the groove 173 is joined to the flange 156 formed on the neck 155 of the movable plate 15) and The second curved portion 172 continues the first portion 171 and extends laterally from the first portion 171. When the movable plate 15 is caused by the manual member to move downward to compress the compression spring 16 and reach the first lower position, the second curved portion 172 is shaped and sized to be biased against the inner wall of the container body 20; and When the manual member 13 rotates upward and the movable plate 15 moves upward due to the compression spring 16 to reach the second upper position, the second curved portion 172 is released. In the first lower position of the movable plate 15, the second curved portion 172 of the sealing member 17 is deflected to expand and form a seal between the lid 10 and the container body 20 (see FIG. 10). The sealing member 17 between the lid 10 and the container body 20 helps preserve the items stored in the container body 20, such as food items and/or drinks. To access the articles stored in the container body 20, the user rotates the manual part 13 upward by 90° to loosen the sealing member 17, causing the sealing member 17 to deviate from the inner wall of the container body 20 and return to its original uncompressed form. And thereby, the lid 10 is released from the container body 20. The user can now easily remove the cap 10 from the container body 20 to access the contents contained therein.

10 and 11, the mechanism for sealing the container 1 by pivoting the manual member 13 mounted on the lid 10 according to the present invention will now be explained. These two figures illustrate the movement of the manual part 13, the movable plate 12 and the sealing member 17.

Figure 10 shows that the lid 10 makes the container body 20 airtight, and the container 1 is in its airtight closed state. As shown, the container 1 has a double-walled structure, which provides a good insulation performance. When the user wants to place the lid 10 above the container body 20 and seal the container body, he can place the free end 132 of the manual part 13 parallel to the manual part 13 (that is, at an angle of 0°) and place it on the top plate With respect to the top plate 12, the manual member 13 pivots downwardly relative to the top plate 12. Because the pivot end 131 of the manual member 13 acts on the protrusion 152 of the movable plate 15, the movable plate 15 is driven to move downward to its first lower position. The extension 134 at the pivot end 131 of the manual member 13 presses the top surface 1521 of the protrusion 152 of the movable plate 15, and therefore when the compression spring 16 is pressed downward, the manual member 13 is flush with the top plate 12. The sealing member 17 engaged with the flange 156 of the movable plate 15 is then forced to bias and press the second curved portion 172 against the inner wall 21 of the container body 20, thereby making the container body 20 airtight (Figure 10). In this closed and sealed state, the container 1 has excellent tightness and thermal insulation.

When the user wants to separate the cover 10 from the container body 20 to place the contents or take the contents stored in the container body 20, the user can set the manual part 13 The free end 132 is turned up by 90°, and the pressure applied by the pivoting end 131 of the manual member 13 to the protrusion 152 of the movable plate 15 is removed, which is compressed by the spring 17 (which always exerts an upward spring force To the movable plate 15) causes the movable plate 15 to move upward to its second upper position. The sealing member 17 is then loosened to restore its uncompressed state (Figure 11). In the uncompressed state, the sealing member 17 is kept at a small distance from the inner wall 21 of the container body 20, thus allowing the lid 10 to be easily rotated away from the container body 20 in a spiral manner.

As discussed above, the bottom plate 14 is fixed to the top plate 12 by buckling the buckling short pieces 143 with the buckling pieces 121, and the bottom plate 14 is essentially the same during the pivoting movement of the manual member 13 The upper part is immovably coupled with the top plate 12. Therefore, the position level of the bottom plate 14 relative to the container body 20 remains unchanged. It is clear that the internal volume of the container 1 (ie, the space defined by the bottom plate 14 and the inner wall 21 of the container 20) will not change during the process of opening or closing the container by the operation of the manual member 13. Unlike the conventional container whose internal volume is reduced due to the increased internal pressure, the closure and sealing of the container 1 through the lid 10 according to the present invention will not reduce the internal volume of the container 1 and therefore the internal pressure will not increase. This provides an effortless solution for opening and closing the sealable container, which is beneficial to the elderly and children.

12 to 18 show a container constructed according to the second preferred embodiment of the present invention. The container of this embodiment has substantially the same structure as the container 1 shown in the first embodiment, and includes a sealable lid 10 and a container body 20, and the lid 10 is placed above the container body. The sealable cover 10 includes a cover body 11 having a top plate 12; a manual part 13 having a pivot end 131 and a free end 132, the pivot end is pivotally connected to the top plate 12, and the free end can be used to operate the manual part; Ground is coupled to the bottom plate 14 of the top plate 12; the movable plate 15 is movably arranged between the top plate 12 and the bottom plate 14; spring structure 16 which is forced to move the movable plate 15 upwards; and a sealing member 18 which is installed to be biased toward or away from the inner wall 21 of the container body 20.

The difference between the cover 10 of this embodiment and the first embodiment is that the top plate 12 is additionally formed with a downwardly extending wall 125, and the wall 125 tightly abuts against the cover body 11, for example, by overmoulding. The inner surface of the circumference 111. In this case, internal threads are formed on the inner surface of the downwardly extending wall 125 of the top plate 12 for mating engagement with corresponding threads formed on the outer surface of the container body. The overmolding of the wall 125 of the top plate 12 and the periphery of the cover body can provide additional protection and insulation of the cover 10 as a whole.

Another difference between the container of this second embodiment and the one discussed in the first embodiment above is the sealing member. The sealing member 18 of this embodiment is shown in FIG. 16. The sealing member 18 is configured to include a first portion 181 having a groove 183 that can be joined to the outer edge of the bottom plate 14 and a second portion 182 that continues the first portion 181 and extends upward from the first portion extend. When the movable plate 15 is squeezed by the manual member 13 to move downward to reach its first lower position, the second part 182 closely abuts the outer surface of the movable plate 15 and is driven to bias against the container The inner wall 21 of the body 20. In this state, the contact area between the sealing member 18 and the container body 20 increases, thereby creating a seal between them (Figure 17). When the manual member 13 is turned up by 90°, the movable plate 15 is driven to move up to its second lower position due to the compression spring 16, the sealing member 18 is then released and keeps a distance from the inner wall 21 of the container body 20. The contact area between the sealing member 18 and the inner wall 21 of the container body 20 is reduced, so that the sealing action is eliminated. The lid 10 is loosely seated on the opening of the container, which is ready to be removed by removing the lid 10 Was turned on.

In the above-described embodiment, except for the metal lower part of the bottom plate In addition, the components of the lid and the container body are preferably made of polymer or plastic, which can be easily manufactured, cleaned and stored. Preferably, the polymer or plastic may be selected from polyoxymethylene (POM) and acrylonitrile butadiene styrene (ABS). However, it should be understood that the lid and other components of the container can be made of any suitable material or materials.

Therefore, the present invention provides a container that includes a container body and a sealable lid with a bottom plate, and regardless of whether the container is opened or closed, the position of the bottom plate is horizontal when the lid is placed above the container body. not changing. This design causes the internal volume of the container to remain unchanged, and this technical effect is achieved by providing a movable plate arranged between the top plate and the bottom plate, which can be lifted or lowered to loosen or compress the sealing member to resist By the container body.

In addition, the container can be easily assembled or disassembled for cleaning purposes because all the components of the lid can be easily separated from each other.

The above description is a preferred embodiment of a sealable lid for a thermally insulated food container. It will be understood that the lid can be used for all types of containers intended to contain solid or liquid contents at any temperature that the material of the container can withstand.

Although the present invention is described with reference to the most practical and preferred embodiments currently considered, it should be understood that the present invention is not limited to the disclosed embodiments, and is intended to cover the spirit and scope of the patent application.
