Description

Technical Field

[0001] The present invention relates to a cap design for a container, and in particular to a cap assembly having a disassembly member for cleaning. The present invention also relates to a container including such a cap assembly. Background Art

[0002] Conventional lids for containers are usually manufactured as one-piece. These conventional lids lead to problems such as difficulty in cleaning and short life of these lids, because the damaged or worn parts in these lids cannot be replaced. Therefore, the present invention seeks to solve these problems, or at least provide an alternative to the public. It is desirable to provide a user with an assembled lid with disassembled parts, which is easy to clean and maintain. By separating the components into independent parts, such as an upper cover, a lower cover, a sealing member, a handle, etc., each part can be cleaned separately, which is difficult or impossible for those one-piece lids. This is particularly important for containers for storing food or drinks, because they need to be kept clean and sanitary. In addition, if the disassembled parts can be easily replaced after being damaged or worn, this can extend the life of the lid and the container to which it is attached. Summary of the invention

[0070] The present invention is now introduced by way of example with reference to the drawings in the following paragraphs. The objects, features, and aspects of the present invention are disclosed in or apparent from the following description. It should be understood by those skilled in the art that the following description is only a description of exemplary embodiments and is not intended to limit the broader aspects of the present invention, which are embodied in the exemplary explanations.

[0071] Figure 1A sealable lid assembly 100 for a container constructed in accordance with a preferred embodiment of the present invention is shown. A container suitable for use with the lid assembly 100 is not shown, but it is understood that the container has an open top and can have any suitable size and / or shape to accommodate different storage items. The assembly of the lid assembly 100 to the container defines the orientation of the lid assembly 100 above the container, defines the container with the lid assembly 100 upright and defines the location of components and the relationship between components described below.

[0072] Figure 2A and 2B An exploded perspective top view and an exploded perspective bottom view of the cap assembly 100 are shown, respectively. The sealable cap assembly 100 includes a cap body 110, a handle portion 120, a rotation stopper 130, a handle 140, a base disc 150, and a sealing ring 160.

[0073] The handle portion 120 is rotatably mounted on the cover body 110 to operably seal or unseal the container with the sealing ring 160. In order to seal or unseal the cover assembly 100 to the container, the user rotates the handle portion 120 between the first position and the second position. When the handle portion 120 is rotated from the first position to the second position, the cover assembly 100 is sealed to the container when the cover assembly 100 is assembled to the container. Rotating the handle portion 120 causes the sealing ring 160 to deform and thereby form a seal between the cover assembly 100 and the container. The sealing ring 160 between the cover assembly 100 and the container helps to preserve items such as food stored in the container. In order to access the contents stored in the container, the user rotates the handle portion 120 back from the second position to the first position to deform the sealing ring 160, causing the sealing ring 160 to return to its original state (i.e., return to its default shape). Therefore, the cover assembly 100 can be released from the container.

[0074] Figure 3A 1 shows a perspective top view of the cover 110. As shown, the top side of the cover 110 has a recessed portion 112 and a hollow cylinder 114 extending upward from the top side of the recessed portion 112. The recessed portion 112 is sized and dimensioned to receive the handle portion 120. The hollow cylinder 114 is preferably cylindrical. Figure 3B As shown, the edge of the cover 110 is a double-wall design including an outer wall 116A and an inner wall 116B, and the outer wall 116A and the inner wall 116B define a groove 118, as shown in FIG. Figure 3B The groove 118 is used to receive the sealing ring 160.

[0075] Figures 4A-4C1 and 2 show different views of the handle portion 120. The handle portion 120 includes a handle 122 and a neck member 124 extending downward from the lower side of the handle 122. Depending on actual needs or manufacturing, the neck member 124 may be a separate part from the handle portion 120 or may be formed integrally with the handle portion 120. The handle portion 120 is received in the groove portion 112 of the cover body 110 by passing the neck member 124 through the hollow cylinder 114 of the cover body 110. The neck member 124 is preferably cylindrical with a pair of oppositely facing vertical walls and has an internal threaded hole. Figure 4B-4C As shown, the oppositely facing vertical walls are provided with a pair of outwardly exposed steps 128. The neck member 124 includes a pair of legs 126 adjacent to the steps 128.

[0076] Reference now Figure 5A and 5B , which shows the shape and configuration of the rotation stop 130. The rotation stop 130 includes a cylindrical bushing having an inner axial bore with a pair of opposed and inwardly facing vertical walls 132, in which the neck member 124 of the handle portion 120 is slidably received. Figure 5B As shown, the rotation stopper 130 is designed to be provided with a pair of legs 134 .

[0077] Fig. 6A and 6B A perspective cross-sectional view and a perspective bottom view are respectively shown of the handle portion 120 coupled to the rotation stop 130. It can be seen that the coupling between the handle portion 120 and the rotation stop 130 is obtained by passing the neck member 124 through the internal threaded axial hole of the cylindrical bushing of the rotation stop 130, wherein a pair of oppositely facing vertical walls of the neck member 124 are coupled to and also slide over a pair of oppositely facing and inwardly facing vertical walls 132 of the rotation stop 130.

[0078] It can also be seen that the axial length of the rotation stopper 130 is smaller than the axial length of the neck member 124, so that the rotation stopper 330 can slide upward and downward relative to the neck member 124 after being installed thereon.

[0079] It can be further seen that in Fig. 6A In the embodiment, the rotation stopper 130 is blocked by the step 128 of the neck member 124 so as to limit and prevent the rotation stopper 130 from sliding further downward to exceed the neck member 124 after being mounted to the neck member 124 . Figure 6A-6BThe mounting between the rotation stopper 130 and the neck member 124 of the handle portion 120 shown in the figure can be disassembled by various methods known in the art. For example, a pair of oppositely facing vertical walls of the neck member 124, preferably with a step 128, are configured to be elastic. When the vertical walls of the neck member 124 (and preferably with a step) are pressed toward each other, the rotation stopper 130 can slide further downward away from the neck member 124 or can slide to cover the neck member 124. Advantageously, the step 128 is configured to be elastic, thereby snapping the step 128 inwardly so that the ring 130 can be covered on the neck member 124. Thereafter, when the inward force is removed, the step 128 returns to its original state and then prevents the ring 130 from leaving the neck member 124. More advantageously, the elasticity provided on the step 128 is achieved by providing two narrow edges on the peripheral wall of the neck member adjacent to the step 128. In a further example, the neck member 124 and the handle 122 of the handle portion 120 are two independently manufactured components. It is understood that when the neck member 124 is detached from the handle 122, the rotation stopper 130 can be removed from the end of the neck member opposite the step 128. The gist of the present invention includes the removable relationship between the rotation stopper 130 and the neck member 124. Therefore, the example described in this context should not be interpreted as any limitation on the scope of the present invention. Since the neck member 124 and the rotation stopper 130 have the above-described features, after the rotation stopper 130 is assembled to the neck member 124, as shown in FIG. Fig. 6A As shown in FIG. 1B , the rotation stopper 130 does not rotate around the neck member 124 and can slide upward and downward relative to the neck member 124 .

[0080] Fig. 7A and 7B The top and bottom views of the handle 140 are shown in perspective, respectively. The handle 140 is a hollow structure and has an external threaded surface that is matingly engaged with the internal threaded hole of the neck member 124. Through the threaded engagement between the handle 140 and the neck member 124, the handle 120 is adapted to rotate clockwise or counterclockwise around the handle 140, whereby the neck member 124 can move between a first position in which the neck member 124 engages with the upper section of the handle 140 and a second position in which the neck member 124 engages with the lower section of the handle 140. A positioning groove 142 extending from the center of the bottom surface of the handle 140 is formed at the lower end of the handle 140, as shown in FIG. Figure 7B shown.

[0081] Figures 8A-8B A base plate 150 is shown, which is arranged on Figure 2A-2BA central groove or depression 152 is provided on the top surface of the base plate 150, where the surrounding wall extends upward from the top side of the base plate 150. A projection 154 and two opposing studs 156 are formed inside the central depression 152 for fixing the assembly of the handle 140 to the base plate 150 by positioning the positioning groove 142 of the handle 140 above the projection 154.

[0082] like Fig.9A As shown, the projection 154 can engage with the positioning groove 142 of the handle 140, and the projection 154 is inserted into the handle 140. The edge of the base plate 150 is a double plate design that defines a groove 158 for receiving the sealing ring 160, as shown in FIG. Figure 8B shown.

[0083] Fig. 9B It is explained how the rotation stop 130 works with a base plate 150 provided with a handle 140. For the sake of simplicity, Fig. 9B The cover 110 and the handle portion 120 are not shown. As can be seen, the rotation stopper 130 is arranged to be installed in the central recessed area 152 and around the handle 140. The rotation stopper 130 is configured to rotate around the handle 140 in the central recessed area 152, where it is designed and manufactured to provide two opposite steps 159 to limit the rotation of the rotation stopper 130 in the central recessed area 152 by limiting the rotation of the corresponding legs 134 of the rotation stopper 130, and thus correspondingly limit the rotation of the handle portion 120, because the handle portion 120 and the rotation stopper 130 are assembled together when the present invention is in use. It should be understood that the rotation of the handle portion 120 is configured to rotate around the handle 140 in a predetermined range, which is determined by the two steps 159 in the central recessed area 152.

[0084] Fig. 9C The assembly of the handle portion 120 to the base plate 150 is shown. For simplicity, Fig. 9C Only a cross-sectional view of the handle portion 120 and the stem 140 is shown, along with the base 150. It can be seen that when the stem 140 is fully received in the threaded hole of the handle portion 120, the leg 126 of the neck member 124 partially overlaps the stud 156 of the base 150, thereby preventing the handle portion 120 from being further rotated in one direction (i.e., toward the stud in the figure).

[0085] Preferably, the neck member 124 and the rotation stop 130 are made of polyoxymethylene (POM), while the handle portion 120, the lid 110, the handle 140 and the base 150 are made of acrylonitrile butadiene styrene (ABS). However, it should be understood that the lid and other components of the container may be made of any suitable material or materials. It should also be understood that the components of the container may be connected or manufactured in any suitable order other than that described above.

[0086] Reference is made to the preceding description and figures, especially with respect to Fig. 6A and 9B 140 and the neck member 124. As can be appreciated from the description, when the present invention is in use, the handle portion 120 is screwed to the handle 140 by screwing in a first direction via the threaded engagement between the external threaded surface of the handle 140 and the internal threaded hole of the neck member 124. Due to the ingenious design of the handle portion 120, the neck member 124 and the rotation stop member 130, it can be appreciated that when Figure 1 When the cap assembly 100 is turned upside down (i.e., the handle portion 120 is turned downward), the rotation stop 130 on the neck member 124 slides toward the end of the neck member adjacent to the handle 122. Then, the handle portion 120 can be configured to be unscrewed from the handle 140 by twisting in a second direction to disengage the threaded engagement between the external threaded surface of the handle 140 and the internal threaded hole of the neck member 124.

[0087] Fig. 10A and 10B The sealing ring 160 of the present invention is shown, which is disposed between the cover 110 and the base 150. The sealing ring 160 is designed and configured to provide a surrounding wall and an inwardly extending portion 162, which extends substantially horizontally from one end of the surrounding wall. The surrounding wall includes a first portion 164 and a second portion 166 adjoining the first portion 164 at a fold 168. Fig. 10A and 10B As shown, the second portion 166 is inclined upward from the extension portion 162 to the first portion 164. The sealing ring 160 is preferably made of silicone or other flexible and / or elastic and / or deformable material (such as plastic). Fig. 10A and 10B In the illustrated embodiment, the sealing ring 160 is configured or manufactured to be suitable for, for example Fig. 10A The first configuration and the second configuration are shown, in which the surrounding wall of the sealing ring 160 protrudes outward at the fold 168. The sealing ring 360 is provided with an outward flange 161 at the periphery of the upper end of the surrounding wall of the sealing ring 160, which facilitates the assembly of the sealing ring 160 to the cover body 110 by fitting the flange 161 into the groove 118 of the cover body 110, as shown in FIG. Fig.11A and 11B shown.

[0088] Fig.11A and 11B An operation of sealing a container by rotating the handle portion 120 of the cap assembly 100 according to the present invention is shown. Fig.11AThe handle portion 120 is shown in a first position wherein the stem 140 is not fully received in the internal threaded bore of the neck member 124 whereby a gap exists between the cover 110 and the base 150 such that the sealing ring 160 is in its first configuration when the handle portion 120 is in its first position. Fig. 11B The handle portion 120 is shown in a second position, wherein the handle 140 is substantially completely received in the internal threaded hole of the neck member 124, whereby the cover body 110 and the base plate 150 are close to each other, so that the sealing ring 160 is compressed or squeezed to deform to its second configuration by bulging outward at the fold 168.

[0089] According to the above description, it should be understood that when a user places and seals the cap assembly 100 on a container (not shown in the figure), the user moves the handle portion 120 from the first position ( Fig.11A ) rotates to the second position ( Fig. 11B ). The lid 110 and the base 150 are brought closer to each other by the interaction between the internal threads of the neck 322 of the handle 320 and the external threads of the stem 340. As a result, the sealing ring 160 is compressed or squeezed to deform to its second configuration with its slightly abutting first portion 164 and second portion 166, so that the sealing ring 160 is forced to deform and deflect toward and press against the container wall, thereby sealing the container. Conversely, when the user moves the handle portion 120 from the second position ( Fig. 11B ) rotates to the first position ( Fig.11A ), the cover body 110 and the base plate 150 are away from each other. Therefore, the sealing ring 160 is relaxed to return to its first configuration, so that the cover assembly 100 can easily remove the deformation of the sealing ring 160 that is forced to deform and deflect toward and press against the container wall.

[0090] It should also be understood that when Figures 11A-11B The assembly in the embodiment is inverted, that is, when the base 150 is positioned above the handle 122, the rotation stop 130 slides to the lower side of the handle 122, and then due to the interaction between the leg 126 of the handle portion 120 and the stud 150 of the base 150, the user can rotate the handle around the stem 140 in only one direction (e.g., clockwise), as shown in FIG. Fig. 9C By rotating the handle clockwise, the user can remove the cover 110 from the cover 110. Figure 6A-6B The assembly shown in FIG. The disassembled handle 122 with the neck member and the rotation stopper can be washed and cleaned. According to the above description, it should also be understood that the cover body 110, the base plate 150 and the sealing ring 160 can be disassembled from each other for cleaning.

Figures 17A-17B Different views of the rotation stop 230 are shown. Fig.17A , it can be seen that the rotation stop 230 is provided with a pair of legs 234, which function in the same manner as the legs 134 described above, and two grooves 238 in the upper portion of the rotation stop 230. Likewise, the rotation stop 230 includes a cylindrical bushing having an internal axial bore with a pair of oppositely facing vertical walls 232 in which the neck member 224 is slidably received. Fig. 17B The inner axial bore is shown provided with a pair of fingers 236 extending inwardly from the cylindrical bushing. Fig.18A , it can be seen that the rotation stop 230 is positioned above the neck member 224, wherein the internal axial hole of the rotation stop 230 is positioned to be aligned above the neck member 224, the pair of fingers 236 of the rotation stop 230 are positioned to be aligned with the guide track 224A of the neck member 224 and the vertical wall 232 of the rotation stop is positioned to be aligned with the slot 224B of the neck member 224. Fig.18A When the rotation stopper 230 in the embodiment moves further downward to surround the neck member 224, as shown in FIG. Fig.18B As shown, it can be seen that due to the interaction between the step 228 of the neck member 224 and the vertical wall 232 of the rotation stopper 230, the rotation stopper 230 is held or fixed by the neck member 224. Due to the design of the neck member 224 and the rotation stopper 230 having the features described above, after the rotation stopper 230 is assembled to the neck member 224, as shown in FIG. Fig.18B As shown, the rotation stopper 230 does not rotate about the neck member 224 and is able to slide upward and downward along the guide track 224A and the slot 224B. Fig.19A 2 shows a perspective bottom view of the handle 222. The underside of the handle 222 is sized and manufactured to provide a recessed area including surrounding vertical walls extending upwardly from the underside of the handle 222.

The arms 274 are each provided with a first protrusion 276A and a second protrusion 276B.

[0094] Fig. 22 2 is a top view of the cover 210. Similar to the cover 110, the cover 210 has a groove portion and a hollow cylinder 214 extending upward from the top side of the groove portion. The hollow cylinder 214 of the cover 210 is provided with two holes 214A facing each other.

[0095] Figures 23A-23B The assembly of the locking device 270 to the cover 210 is shown. Fig.23A As seen in FIG. 8 , the second protrusion 276B rests on the recessed portion of the cover 210 . Fig. 23B The bottom side of the cover 210 is shown to be provided with two oppositely facing narrow edges 216 for coupling with two grooves 252, as shown in FIG. Fig. 14BThe two grooves 252 are shown facing each other in the base 250. The interaction between the narrow edge 216 and the groove 252 assists the user in assembling the cover 210 and the base 250 to each other in the correct order in the predetermined orientation.

[0096] Figures 24A-24B The transition of the locked state of the cover assembly 200 is shown, wherein Fig.24A shows the state of the cover assembly 200 during the locking process, and Fig. 24B The fully locked state of the cover assembly 200 is shown. For simplicity, these figures show the function and operation of the locking device 270 in a three-dimensional elevation view including the handle 222 and the locking device 270. As described above, it should be understood that the handle 222 can be configured to rotate around the hollow cylinder 214 of the cover body 210 and the handle 240 between its first and second positions. Fig.24A -B, it can be seen that the first projection 276A of the locking device 270 and the hole 214A of the cylinder 214 of the cover are positioned slightly offset from the symmetry axis of the cover 210. Fig.24A , which shows that the second pair of protrusions 222B of the handle 222 are approaching the first protrusion 276A of the locking device 270. Fig.24A When the handle 222 in the middle is further rotated clockwise, the second pair of protrusions 222B slide over the first protrusion 276A. Since the central recessed area is designed and manufactured to provide two opposite steps to limit the rotation of the rotation stop in the central recessed area by limiting the rotation of the corresponding legs of the rotation stop, the rotation stop 230 is Fig. 24B The handle 222 in the lock mechanism 270 is thus unable to rotate further clockwise. In other words, the rotation stopper 230 is only allowed to rotate counterclockwise together with the handle 222. By means of the interaction between the first protrusion 276A of the locking device 270 and the protrusion 222B of the handle 222, the position of the handle can be protected and prevented from being changed by unintentional operation, thereby providing a lock for the handle. Based on the above description, it should be understood that in Fig. 24B The handle 222 in the embodiment is only allowed to rotate counterclockwise 90 degrees. It should also be understood that when Fig. 24B When the assembly in the embodiment is turned upside down, that is, the base plate 250 is located above the handle 222, the rotation stopper 230 slides to the lower side of the handle 222, and then the user can rotate the handle in only one direction (e.g., clockwise) to remove the cover 210 from the cover 210. Fig. 20A - The assembly shown in B (due to the interaction between the legs of the handle and the studs of the base as explained previously). The disassembled handle 222 with the neck piece and rotation stop can be washed for cleaning. Based on the above description, it should also be understood that the cover 210, the base 250 and the sealing ring 260 can be disassembled from each other for cleaning.
