Description

  The present invention relates to a container having a stackable top lid and a bottom surface.

  Sealable containers are well known in the art. Sealable containers are used to organize and store perishable food and other items. Such a sealing function of the container serves to prevent the contents of the container from being exposed to environmental elements including, for example, dust around the container. Sealable containers may be made from various materials and formed in various thicknesses to meet the needs of the user. For example, some sealable containers are durable and can be used repeatedly, but some are expensive. Other sealable containers are extremely thin and inexpensive so that they are affordable and disposable, but are not durable. Finally, some plastic sealable containers are designed to be durable enough to be durable and inexpensive enough to be discarded by consumers after a limited or long-term use as required. There is something. Furthermore, storing empty sealable containers as present in the art can be problematic because the top lids of the containers do not stack together.

  The present invention provides the container with functions not found in the art. These and other advantages and further inventive features of the present invention will become apparent from the description of the invention set forth herein.

  The present invention provides a container comprising a container bottom and a container upper lid. The container bottom defines a cavity and has a container bottom sealing portion. The container top defines a cavity and has a container top closure portion, a first nesting portion disposed along the circumference of the container top lid cavity, and a second nesting portion disposed along the circumference of the container top lid cavity. . When the container top lid is in a straight state, the container bottom sealing portion can be connected to the container top lid sealing portion to seal the plastic container. When the container top is inverted and fitted into the cavity at the bottom of the container, the first and second nested parts contact the container bottom at two different parts of the container bottom.

  The present invention also provides a container top that defines a cavity. The container top is disposed along the perimeter of the cavity to accommodate the lock portion disposed around the cavity to engage the adjacent plastic container top and the lock portion of the adjacent plastic container top lid. And a receiving portion. When the first adjacent container top lid is fitted into the cavity, the locking portion engages the receiving portion of the adjacent container top lid to form a container top stack. When the container top is fitted into the cavity of the second adjacent container top, the receiving portion of the container top is engaged by the lock portion of the second adjacent container top to form a container top stack.

  The present invention further provides a container top that defines a cavity, the container top being an inwardly curved portion disposed along the periphery of the cavity, an outwardly curved portion disposed along the periphery of the cavity, and It has a nesting portion arranged along the circumference of the cavity. When the first adjacent container top lid is fitted into the cavity, the inwardly curved portion is in contact with the outwardly curved portion of the first adjacent container top lid, and the nested portion is in contact with the nested portion of the first adjacent container top lid. To form a container top lid stack. When the container upper lid is fitted into the cavity of the second adjacent container upper lid, the outwardly curved portion of the container upper lid is in contact with the inwardly curved portion of the second adjacent container upper lid, and the nesting portion is the second adjacent container. A container top lid stack is formed in contact with the nesting portion of the top lid.

  Referring to FIG. 1, the container 100 includes a container upper lid 102 and a container bottom 104. The container top lid 102 and the container bottom 104 are connected to each other to form a seal. The container is preferably made from a plastic material, but those skilled in the art will appreciate that other materials can be used. Referring to FIG. 2, the container bottom has a bottom surface 106, a side wall 108 and a sealing portion 110. Side wall 108 extends upward from bottom surface 106 to define a storage cavity. The sealing portion 110 extends outward from the upper side of the side wall 108. The bottom surface 106 may have a recess 112. Referring to FIG. 4, the container top lid 102 may have a decorative portion 114 on the top surface 116. The recess 112 shown in FIG. 2 can be used by way of example and not limitation to house the decorative portion 114 on the upper surface 116 of the container top lid 102 when stacked on another container 100. As shown in FIG. 3, the container bottom 104 may have a substantially rectangular shape. However, those skilled in the art will appreciate that the present invention is applicable to other container shapes including, but not limited to, for example, a circle.

  Referring to FIG. 4, the container upper lid 102 has an upper surface 116, a side wall 118, and a sealing portion 120. Sidewall 118 extends downward from top surface 116 to define a cavity. The sealing portion 120 extends downward from the side wall 118. The container 100 can be sealed by placing a container top lid 102 near the container bottom 104 and applying force. In order to separate the container top lid 102 from the container bottom 104, a separation tab 122 is provided so as to have a surface that the user grasps when applying a force to separate the respective sealing portions 120, 110 of the container top lid 102 and the container bottom 104. Can do. The top surface 116 can have a recess 124 surrounded by a stabilizing rim 126 for stabilizing the container 100 stacked on the container top lid 102. The container top lid 102 can also have a decorative portion 114 of some shape. As shown in FIG. 5, the shape of the container upper lid 102 may be substantially square. However, those skilled in the art will appreciate that the present invention is applicable to other container shapes including, but not limited to, for example, a circle. FIG. 6 shows the container top lid 102 in an inverted state. When inverted, the cavity defined by the top surface 116 and the side wall 118 will face upward rather than downward. In the inverted state, the container upper lid 102 can be used as a dish or a bowl.

  7 and 8 show the container top lid 102 attached to the container bottom 104. The container upper lid 102 has a container upper lid sealing portion 120. The container top lid sealing portion 120 has an outwardly projecting portion 128, an outwardly curved portion 130, an inwardly curved portion 132, and a gripping portion 134 that is folded back. The container bottom 104 has a container bottom sealing portion 110. The container bottom sealing portion 110 has an outwardly extending portion 136, an outwardly curved portion 138, an inwardly curved portion 140, and a gripping portion 142 that is folded down. When the container top lid 102 is disposed adjacent to the container bottom 104, the inwardly curved portion 132 of the container top lid sealing portion 120 contacts the outwardly curved portion 138 of the container bottom seal portion 110. When pressure is applied, each sealing portion 120, 110 is slightly deflected and the inwardly curved portion 132 of the container top lid sealing portion 120 slips over the outwardly curved portion 138 of the container bottom sealing portion 110 to overcome the container 100. Can be sealed. When the container 100 is sealed, the outwardly extending portion 128, the outwardly curved portion 130 and the inwardly curved portion 132 of the container top lid sealing portion 120 become the outwardly extending portion 136, outwardly curved portion of the container bottom sealing portion 110. The portion 138 and the inwardly curved portion 140 are disposed adjacent to each other. The cavity defined by the top surface 116 and the side wall 118 of the container top lid 102 accommodates over-packing of the container 100 by providing extra storage space for the material stacked higher than the side wall 108 of the container bottom 104. Each gripping portion 134, 142 may be used to grasp and hold the container 100 and may be used to assist in separating the container top lid 102 from the container bottom 104.

  As shown in FIG. 9, a plurality of containers 100a, 100b can be stacked on top to form a container stack 170. When a container 100 is on top of another container 100, the bottom surface 106a of the container bottom 104a of the container 100a above fits into the recess 124b of the top surface 116b of the container top lid 102b of the container 100b below. A stabilizing rim 126b on the upper surface 116b of the underlying container 100b helps to limit the lateral movement of the underlying container 100a, thereby stabilizing the stack. The stabilizing rim 126b also helps to center the container stack 170 to prevent tilting while maintaining the center of gravity of the container stack 170 relatively central. When the container 100a is placed on top of another container 100b, the bottom surface 106a of the upper container 100a protrudes from the outside of the stabilizing rim 126b of the lower container 100b or the stabilizing rim of the lower container 100b. The user will know that the container stack is not properly centered because 106a tilts the overlying container 100a.

  Referring to FIG. 10, according to the present invention, the container top lid 102 can be inverted and fitted into the cavity of the container bottom 104 to adapt to fill the container bottom 104. The cavity defined by the upper surface 116 and the side wall 118 of the container top lid 102 contains the material in this cavity. Accordingly, when the container upper lid 102 is upside down, the container 100 has two accommodation areas. For example, the container top 102 is used to contain potato chips and the container bottom 104 is used to contain a sauce. When not in use, the sauce is protected by the container top lid 102. When the user wants to use the sauce, the user only needs to remove the container lid 102.

  The inverted container top lid 102 and the container bottom 104 come into contact with each other at a plurality of portions. By contacting at a plurality of portions, the stability and sealing performance of the container upper lid 102 in an inverted state are enhanced. As can be seen in FIG. 11, by way of example and not limitation, when the container top 102 is upside down, the container top 102 contacts the container bottom 104 at the two portions 148, 150 to prevent intrusion of dust and other objects. Helps to prevent and retain the contents contained in the container bottom 104. A first contact portion 148 occurs between the first nesting portion 172 along the periphery of the container top lid 102 and the side wall 108 of the container bottom 104. Between the second nesting portion 174 along the periphery of the container top lid 102 and the portion of the container bottom 104 that extends outwardly 136 of the sealing portion 110 and the portion of the container bottom 104 that is near the portion where the side wall 108 meets. A second contact portion 150 occurs. However, those skilled in the art will understand that the relative positions of the contact portions may be in different portions from the illustrated portions of the container top lid 102 and the container bottom 104, and the number of contact portions is not limited to two. .

  Also, since the container top lid 102 can be inverted, an additional function is provided that allows the containers to be stacked at two different heights. For example, as shown in FIG. 12, the upper container 100c fits into the cavity of the container upper lid 102d of the lower container 100d to reduce the actual stacking height. This stacking configuration may be desirable when the user wants to reduce the stacking height and when the user does not need the extra storage space provided by the container top lid 102d in a straight state.

  As shown in FIG. 13, the container top lid 102 shown upside down has a locking portion 158 disposed along the periphery of the cavity and a receiving portion 160 disposed along the periphery of the cavity. As shown in FIG. 14, a plurality of container top lids 102a, 102b, 102c shown upside down can be stacked on top of each other to form a container top lid stack 156. According to the present invention, when the first container upper lid 102a is fitted in the cavity of the second container upper lid 102b, the lock portion 158b of the second container upper lid 102b is the accommodating portion 160a of the first container upper lid 102a. To form a container top lid stack 156. As shown in FIG. 13, the lock portion 158 has a protruding rib, and the receiving portion 160 has a concave groove. In other embodiments, the locking portion 158 may include a convex portion or rib, a concave portion or rib, a straight or curved undercut, a straight or curved cross section, a separate snap element or button to allow engagement. , One or more of features such as an interference fit, a textured surface, or an element that changes surface friction or adhesion at or around the engagement site. The engagement region that creates the locked state may be continuous around the cavity or may be divided discretely around the cavity. Advantageously, the locking portion 158 of the top lid 102 is designed to provide tactile and auditory feedback when the locking portion 158 is engaged. Still another container top lid 102 can be added to the stack 156. For example, when the second container upper lid 102b is fitted into the cavity of the third container upper lid 102c, the receiving portion 160b of the second container upper lid 102b is engaged with the lock portion 158c of the third container upper lid 102c. Thus, the number of the container upper lids 102 in the container upper lid stack 156 increases. By engaging the locking portion 158 of the container top lid 102 with the receiving portion 160 of the adjacent container top lid 102, the container top lids 102 are securely connected to each other so that when the user places the container top lid 102, they are You don't have to worry about shifting each other. The top lid stack 156 resists shaking and dropping, and individual container top lids 102 in the stack 156 can remain locked without shifting vertically or horizontally, thereby compromising the integrity of the stack. Absent. An inwardly curved portion 132 and an outwardly curved portion 130 are disposed along the periphery of the container top lid 102 to provide a second contact portion with the adjacent container top lid 102 to improve the stability of the container top lid stack 156. It can be further increased.

  15 and 16, in order to efficiently store and stack, a plurality of container bottom portions 104d and 104e can be stacked and a plurality of container top lids 102d and 102e can be stacked thereon. The lock portion 158e and the receiving portion 160d prevent the container top lids 102d and 102e from falling apart, and the container top lids 102d and 102e fit into the cavity of the top container bottom 104d with at least two contact portions 148 and 150. Thus, a large number of container top lids 102 and container bottoms 104 can be securely stored within a single container top lid and container bottom stack 162. According to the present invention, vertically stacked stacks are maintained in a relatively orderly and centered manner without tilting, so that several container stacks can also be placed individually next to each other. This ability to stack individually is whether the stack consists of a plurality of container bottoms 104 stacked together with the container top lid 102 on top or a plurality of containers 100 stacked with the container top lid 102 straight. It is applied to the container 100 regardless of whether it is composed of a plurality of containers 100 stacked with the container upper lid 102 in an inverted state.

  Referring to FIG. 17, the container 200 includes a container upper lid 202 and a container bottom 204. The container 200 is similar to the container 100 of FIG. 1, but the container top lid 202 does not lock with the adjacent container top lid when stacked. The container top lid 202 and the container bottom 204 can be connected together to form a seal. Although the container is preferably made from a plastic material, those skilled in the art will appreciate that other materials may be used. Referring to FIG. 18, the container bottom 204 has a bottom surface 206, a side wall 208, and a sealing portion 210. Side wall 208 extends upward from bottom surface 206 to define a cavity for receiving. The sealing portion 210 extends above the outside of the side wall 208. The bottom surface 206 can have a recess 212. By way of example and not limitation, the recess 212 is used to receive a decorative portion 214 on the top surface of the container top lid 202 as shown in FIG. 20 when stacked on another container 200. As shown in FIG. 19, the shape of the container bottom portion 204 may be substantially rectangular. However, those skilled in the art will appreciate that the present invention is applicable to other container shapes including, but not limited to, for example, a circle.

  Referring to FIG. 20, the container upper lid 202 has an upper surface 216, a side wall 218, and a sealing portion 220. Sidewall 218 extends downward from upper surface 216 to define a cavity. The sealing portion 220 extends outward and downward from the side wall 218. The container 200 can be sealed by placing a container upper lid 202 on the container bottom 204 and applying a force. When separating the container top lid 202 from the container bottom 204, the user can grasp the respective sealed portions 220, 210 of the container top lid 202 and the container bottom 204. In another embodiment, a separation tab, such as 122 shown in FIG. 4, is provided so that the user has a surface to grip when applying a force to separate the respective sealing portions 220, 210 of the container top lid 202 and the container bottom 204. It may be provided. The top surface 216 can have a recess 224 surrounded by a stabilizing rim 226 for stabilizing the container 200 stacked on the container top lid 202. The container top lid 202 can also have a decorative portion 214 of some shape. As shown in FIG. 21, the shape of the container upper lid 202 may be substantially rectangular. However, those skilled in the art will appreciate that the present invention is applicable to other container shapes including, but not limited to, circular, for example. FIG. 22 shows the container top lid 202 in an inverted state. When upside down, the cavity defined by upper surface 216 and sidewall 218 faces upward rather than downward. In the upside down state, the container upper lid 202 can be used as a dish or a bowl.

  23 and 24 show the container top lid 202 attached to the container bottom 204. The container upper lid 202 has a container upper lid sealing portion 220. The container top lid sealing portion 220 has an outwardly extending portion 228, an outwardly curved portion 230, an inwardly curved portion 232, and a gripping portion 234 that is folded back. The container bottom part 204 has a container bottom part sealing part 210. The container bottom sealing part 210 has an outwardly extending part 236, an outwardly curved part 238, an inwardly curved part 240, and a gripping part 242 folded down. When the container top lid 202 is disposed adjacent to the container bottom portion 204, the inwardly curved portion 232 of the container top lid sealing portion 220 contacts the outwardly curved portion 238 of the container bottom sealing portion 210. When pressure is applied, each of the sealing portions 220, 210 bends slightly and the inner curved portion 232 of the container top lid sealing portion 210 slides over the outer curved portion 238 of the container bottom sealing portion 210 over the container 200. Be able to seal. When the container 200 is sealed, the outwardly extending part 228, the outwardly curved part 230, and the inwardly curved part 232 of the container top lid sealing part 220 are the outwardly extending part 236 of the container bottom sealing part 210, the outside A flared portion 238 and an inwardly curved portion 240 are disposed adjacent to each other. The cavity defined by the top surface 216 and side wall 218 of the container top lid 202 accommodates overfilling of the container 200 by providing extra storage space for material stacked above the side wall 208 of the container bottom 204. Each gripping portion 234, 242 can be used to grip and hold the container 200 and can also be used to assist in separating the container top lid 202 from the container bottom 204.

  As shown in FIG. 25, a plurality of containers 200a, 200b can be stacked on each other to form a container stack 270. When a container is on top of another container 200, the bottom surface 206a of the container bottom 204a of the container 200a above fits in the recess 224b of the top surface 216b of the container top lid 202b of the container 200b below. A stabilizing rim 226b on the upper surface 216b of the underlying container 200b serves to limit the lateral movement of the underlying container 200a, thereby helping to stabilize the stack. The stabilizing rim 226b also helps to center the container stack 270 to prevent the center of gravity of the container stack 270 from being relatively centered and tilted. When the container 200a is placed on top of another container 200b, the bottom surface 206a of the upper container 200a protrudes outside the stabilizing rim 226b of the lower container 200b, or stabilizes the lower container 200b. The user will know that the container stack 270 is not properly centered because the rim 226b tilts the container 200a on top.

  Referring to FIG. 26, according to the present invention, the container top lid 202 can be turned upside down and fit into the cavity of the container bottom 204 to fill the container bottom 204. The cavity defined by the top surface 216 and the side wall 218 of the container top lid 202 contains material within the cavity. Accordingly, the container 200 has two storage areas with the container upper lid 202 upside down. For example, the container top lid 202 can be used to contain potato chips and the container bottom 204 can be used to contain the sauce. When not in use, the source is protected by the container top lid 202. When the user wants to use the sauce, she only needs to remove the container top lid 202.

  The inverted container top lid 202 and the container bottom portion 204 are in contact with each other at a plurality of portions. Since there are a plurality of contact portions, the stability and sealing performance of the container top lid 202 in an inverted state are improved. As can be seen in FIG. 27, by way of example and not limitation, when the container top lid 202 is upside down, the container top lid 202 contacts the container bottom 204 at the two portions 248, 250 to allow dust and other objects to enter. And helps to preserve the contents contained in the container bottom 204. A first contact portion 248 occurs between the first nesting portion 272 and the side wall 208 of the container bottom 204 along the periphery of the container top lid 202. Between the second nesting portion 274 along the periphery of the container top lid 202 and the portion of the container bottom 204 that extends outwardly 236 of the sealing portion 210 and the portion near the intersection of the sidewalls 208 of the container bottom 204. A second contact portion 250 occurs. However, those skilled in the art understand that the relative positions of the two contact portions may be different from the illustrated portions of the container top lid 202 and the container bottom portion 204, and the number of contact portions is not limited to two. Will.

  Since the container top lid 202 can be inverted, an additional function is also provided that allows the containers to be stacked at two different heights. For example, as shown in FIG. 28, the upper container 200c is accommodated in the cavity of the container upper lid 202d of the lower container 200d, and the actual stacking height is lowered. This stacking configuration may be desirable when the user wants to reduce the stacking height and when the user does not need the extra storage space provided by the straight container top lid 202d.

  As shown in FIG. 29, the container top lid 202 shown upside down has an inwardly curved portion 232, an outwardly curved portion 230, and a nested portion 264 disposed along the perimeter of the cavity. As shown in FIG. 30, a plurality of container top lids shown upside down can be stacked on each other to form a container top lid stack 256. According to the present invention, when the first container upper lid 202a is fitted into the cavity of the second container upper lid 202b, the outwardly curved portion 230a of the first container upper lid 202a is formed on the inner side of the second container upper lid 202b. The nesting portions 264a and 264b of the first and second container upper lids 202a and 202b are in contact with each other, in contact with the cuboid portion 232b. In other embodiments, the contact portion may be an interference fit, a straight cross section, a curved cross section, a textured surface, or an element that changes surface friction or tack around or around the engagement point to allow engagement. You can have one or more of them. The engaging portion that creates the contact state may be continuous around the nested portion or may be divided discretely around the nested portion. A container top lid 202 can be further added to the stack 256. For example, when the second container upper lid 202b is fitted in the cavity of the third container upper lid 202c, the outwardly curved portion 230b of the second container upper lid 202b becomes the inwardly curved portion 232c of the third container upper lid 202c. And the nesting portions 264b and 264c of the second and third container upper lids 202b and 202c are in contact with each other. These two contact portions 266, 268 between adjacent container tops 202a, 202b, 202c allow the container tops 202a, 202b, 202c to be securely contained within one another so that the user can use the container tops 202a, 202b. , 202c can be stored without having to worry about their displacement.

  31 and 32, in order to efficiently store and stack, a plurality of container bottom portions 204e and 204d can be stacked, and a plurality of container top lids 202d and 202e can be stacked thereon. Since the container top lids 202d and 202e can be brought together and the container top lids 202d and 202e can be brought into contact with each other in at least two locations 248 and 250 to fit in the cavity of the top container bottom 204d, a large number of container top lids 202 and containers The bottom 204 can be securely housed in a single container top lid and container bottom stack 262. Also, because the present invention maintains vertically oriented stacks in a relatively tidy and centered state without tilt, several stacks of containers can be placed individually next to each other. This ability to stack individually is that the stack consists of a plurality of container bottoms 204 stacked together with the container top lid 202 positioned on top, or from a plurality of containers 200 stacked with the container top lid 202 straight. It is applied to the container 200 regardless of whether it is composed of a plurality of containers 200 stacked with the container upper lid 202 in an inverted state.
