The present invention generally relates to apparatuses for sealing bags, and more particularly, hinged closure apparatuses for sealing bags in a childproof, tamperproof, or airtight manner.
In many applications, a user of a bag or other flexible open container may wish to seal the bag or container to prevent items inside from escaping, to prevent spoilage of contents, or for any of a variety of other reasons. In addition, the user may wish to open and close the seal multiple times so as to have access to the contents as needed. Thus, various closure apparatuses have been made available for the sealing of bags in a temporary manner.
Many of these closure apparatuses are designed to allow a user to open and close a bag with as much ease and efficiency as possible, some of which employ a simple fastening mechanism to maintain closure of the bag. The fastening mechanism may be released with a single user action in order to allow quick and easy access to the bag's contents. In addition, the available closure apparatuses may seal a bag in such manner as to allow the bag's contents some degree of leakage or exposure to outside air.
As can be seen, there is a need for an improved hinged closure apparatus that may securely seal a bag or flexible container in a childproof, tamperproof, and airtight manner.
In one aspect of the present invention a hinged closure apparatus comprises a first limb having a first elongated panel with a first hinged end and a first free end opposite the first hinged end, and a first sealing member coupled with the first elongated panel and extending along a length of the first elongated panel; a second limb having a second elongated panel with a second hinged end and a second free end opposite the second hinged end, and a second sealing member coupled with the second elongated panel and extending along a length of the second elongated panel, wherein the second hinged end is movably coupled with the first hinged end; and a locking mechanism coupled with at least one of the first limb or the second limb, wherein the locking mechanism is adjustable to be in a locked position such that the first free end is removably fastened with the second free end and a seal is formed between a surface of the first sealing member and a surface of the second sealing member, the locking mechanism is releasable into an unlocked position such that the first free end is detached from the second free end, and a release from the locked position into the unlocked position requires simultaneously a first unlocking action and a second unlocking action.
In another aspect of the present invention, a hinged closure apparatus comprises a first elongated limb having a first hinged end, a first free end opposite the first hinged end, and a protruding structure extending from the first hinged end to the first free end, the protruding structure including a main branch extending outwardly from the first elongated limb, and at least one subbranch extending laterally outward from the main branch; a second elongated limb having a second hinged end, wherein the second hinged end is movably coupled with the first hinged end, a second free end opposite the second hinged end, and a recessed structure extending from the second hinged end to the second free end; and a locking mechanism coupled with at least one of the first elongated limb or the second elongated limb, wherein the locking mechanism is adjustable to be in a locked position, such that the first free end is removably fastened with the second free end, the protruding structure is received within the recessed structure, and a seal is formed between and along a length of the protruding structure and a length of the recessed structure.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Various inventive features are described below that can each be used independently of one another or in combination with other features. However, any single inventive feature may not address any of the problems discussed above or may only address one of the problems discussed above. Further, one or more of the problems discussed above may not be fully addressed by any of the features described below.
Broadly, embodiments of the present invention generally provide a hinged closure apparatus for the secure sealing of bags or other flexible open containers. The closure apparatus may include a childproof locking mechanism requiring a two-step opening process that may be difficult for children to perform. Such a locking mechanism may provide a secure form of closure so as to prevent the accidental opening of the seal and the resulting spillage or exposure of contents within a bag. The locking mechanism may require more than a single action to be released, but may also be reasonably feasible and not overly cumbersome for an average adult user.
In addition, some embodiments of the closure apparatus may form an airtight seal along a bag, when the bag is locked within the apparatus. The airtight seal may prevent exposure of the bag's contents to outside air, release of odors from the bag's contents, or leakage of liquid from within the bag.
Some embodiments of the closure apparatus may also provide tamper-evident enabling features, which may deter the unauthorized opening of the seal. The closure apparatus may be produced with an attached bag, or as an independent product that may be used with a variety of bags or flexible containers.
The first limb 110 may have a first elongated panel 120 with a first hinged end 112 and a first free end 114 opposite the first hinged end 112. A length 122 (as shown in
The hinged closure apparatus 100 may include a locking mechanism 200 arranged such that when the locking mechanism 200 is in a locked position such as that shown in
The locking mechanism 200 may require a two-step user action in order to be released into an unlocked position such as that shown in
The locking mechanism 200 may be coupled with at least one of the first limb 110 or the second limb 160. The locking mechanism 200 may be adjustable to be in a locked position such that the first free end 114 may be removably fastened with the second free end 164. In the locked position, such as that shown in
The locking mechanism 200 may be releasable into an unlocked position such that the first free end 114 is detached from the second free end 164. A release from the locked position (such as that shown in
The locking mechanism 200 may include a first hook 210 coupled with the first free end 114 and a second hook 230 coupled with the second free end 164, the first hook 210 being latched to the second hook 230 when the locking mechanism 200 is in the locked position. In order to release the locking mechanism 200 from a locked position to an unlocked position, a user may first perform a first unlocking action. The first unlocking action may include pressure on the first hook 210 in an unlatching direction 212, as indicated in
As shown in the embodiment of
The first hook 210 may be coupled with the first free end 114 such that it hooks in a substantially upward direction. As indicated in the close-up drawings of
The second hook 230 may be coupled with the second free end 164 such that it hooks in a substantially downward direction. As indicated in the close-up drawings of
The limbs 110 and 160 or the locking mechanism 200 may be fully or partially formed using flexible material, such as but not limited to polyurethane, polypropylene and nylon. The surface of the first free end 114 may include a ribbed portion 240 or other form of texture, which may provide friction or increased security for a user's finger while pushing the first free end 114 in the unlatching direction 212. Other design features, which may aid in the general handling of the hinged closure apparatus 100, may also be included. As an example, design formations such as openings 128A-F may provide an aesthetic feature or friction against a user's fingers for ease of handling.
As another example, the first elongated panel 120 may include a first depressed portion 124 at an inner portion of the first elongated panel 120. A first reinforced portion 242 may surround the first depressed portion 124. The second elongated panel 170 may include a second depressed portion 174 at an inner portion of the second elongated panel 170. A second reinforced portion 244 may surround the second depressed portion 174. The depressed portions 124 and 174, along with the reinforced portions 242 and 244, may provide added ease of handling or security while being held by a user's fingers.
In addition, the first hook 210 may have a width similar to that of the first reinforced portion 242, and the second hook 230 may have a width similar to that of the second reinforced portion 244. The first hook 210, second hook 230, or connecting structure 236 may be formed with sufficient width so as to prevent accidental lateral unlatching of the hooks 210 and 230 while in a locked position.
However, the first hook 210 and the second hook 230 may be coupled in alternative manners with the first limb 110, the second limb 160 or both. The hooks 210 and 230 may also be latched in alternative configurations requiring the unlatching of one hook prior to the unlocking movement of the other hook, such as by, but not limited to, movement in opposing lateral directions of the hooks. The hooks 210 and 230 may be formed or coupled with the free ends 114 and 164, or other portions of limbs 110 and 160, in a variety of configurations and are not limited to the description above.
Further, the locking mechanism 200 may employ structures other than hooks in order to removably fasten the first free end 114 and the second free end 164 in a childproof manner. Other fastening structures which may require the simultaneous performance of a first user action and a second user action, in order to become unfastened, are contemplated within the scope of this invention.
