Description

  An improved container-sealer structure is disclosed, for example, where at least the seal (eg, lid) is molded from plastic.

  Plastic and metal containers such as buckets are used to hold chemical products including paints, solvents, oils, powders and the like. It is desirable to prevent the seal from being removed from the container because the container has been inadvertently dropped and / or due to movement of the load, such as during handling and transportation. At the same time, it is desirable that the seal can be easily removed when the contents of the container are needed.

[Overview]
A first container-sealer structure,
(I) A container having a bottom and an outer peripheral wall, the rim forming the upper edge of the wall and surrounding the opening of the container, and the outer bead being integrally formed with the rim and surrounding the rim A container having an inner bead integrally molded with the rim so as to surround the rim and projecting inward of the container;
(Ii) a seal having a sealing portion adapted to be overlie the opening of the container, wherein the skirt is integrally formed with the sealing portion and when the sealing device is attached to the container; A skirt is positioned to surround the rim and a skirt is positioned adjacent to the outer top edge of the rim to surround it, and is fragilely connected to the first portion and extends downwardly therefrom. , Thereby having a second part provided with a band adapted to surround the lower part of the upper end of the rim, the second part having a first ledge that is formed integrally therewith And the first ledge is positionable to be in a position for meshing engagement with the outer bead, and the second ledge is integrally formed with the sealing portion and is in a position for meshing engagement with the inner bead. It is positionable, and a closed vessel,
With
The second part can be disconnected from the first part when the seal is attached to the container, thereby removing the second part from the seal and releasing the meshing engagement with the outer bead of the second part. A first container-sealer structure is provided.

  The meshing engagement of the first ledge and the outer bead can provide a “main lock” of the seal to the container, and the meshing engagement of the second ledge and the inner bead can provide an “auxiliary lock” of the seal to the container. It can be performed.

  For this reason, the main lock is released by the separation of the second portion, and the sealer can be removed from the container.

  In this regard, once the main lock is disconnected, the auxiliary lock need only be removed to remove the seal from the container. In other words, once the second part has been separated from the first part, the second ledge can be removed from the inner bead, whereby the seal can be removed from the container. Thereafter, when the seal is reattached to the container, the auxiliary lock can be re-engaged (by the second ledge and the inner bead) so that the seal can be securely reattached to the container.

  Thus, the second portion can function as a cut band or strip that can indicate that the attachment of the seal to the container has been tampered with. Alternatively, the fragile connection between the first and second parts can be defined as a tear line (which can be easily cut with a knife and a cutting tool, etc.) and again a mischief with respect to the tear line can be detected.

  In addition, providing a main lock and auxiliary lock for transportation and storage facilitates safer and more secure attachment of the seal to the container, so that when the seal is first attached to the container, it must be sealed. The vessel is secured to the container on each side of the rim.

  In one embodiment, the seal flange can be integrally formed with the seal skirt and extended outward therefrom, thereby facilitating removal of the seal from the container. In this embodiment, the seal flange can be integrally formed with the first portion and then extended outwardly. For this reason, once the second portion is separated from the first portion, the second ledge can be removed from the inner bead by lifting the seal flange. As a result, the first portion can be bent away from the rim and the second ledge can be moved beyond the inner bead.

  In another embodiment, the second portion has a thickness that allows the first ledge to engage the outer bead and press into the engaged position after the first ledge has moved past the outer bead while the seal is attached to the container. Can have. In this regard, the first ledge can be located below and / or behind the outer bead.

  In a further embodiment, the container flange can be integrally formed with the container wall below the rim and can extend outwardly therefrom. In this regard, when the seal is attached to the container, the distal end of the second portion of the skirt may be positionable adjacent the container flange. Placing the distal end of the second portion adjacent to the container flange can help prevent tampering of the structure. The container flange can also function to reinforce the container.

  The container flange cooperates with the outer bead to define an outer channel extending around the rim so that the first ledge can be received within the outer channel when the seal is attached to the container. In addition, the container flange is formed to protrude further laterally than the skirt from the container, thereby providing protection of the skirt during transport of the structure.

  In yet another embodiment, the sealed portion has a land that connects to the skirt at one end, the skirt depends from the end, the land connects to the wall portion at the other end, and the wall portion is The other end extends downward. The skirt, land, and wall portions cooperate to define a generally U-shaped channel so that the container rim can be received within the U-shaped channel when the seal is attached to the container rim. The first and second ledges protrude from the skirt and wall portions into the U-shaped channel, respectively.

  In a further embodiment, the second ledge can protrude from the land into the U-shaped channel, in addition, the inner skirt can protrude from the land or wall portion, and the distal end of the inner skirt can be Positioned to engage an inner ledge defined within the container wall. The inner skirt can provide support for the stack of containers. For example, when the loaded second container is stacked on top of the assembled first container-closer structure, the inner skirt can transmit the mass of the second container from the first seal to the first container wall.

  In a further embodiment, a sealing structure is provided between the first part and the adjacent container rim. The sealing structure may have a protrusion on either the first part or the rim and a corresponding recess on either the rim or the first part, the recess protruding when the seal is attached to the container. The part is accommodated inside. The protrusion is housed in a recess with a close or snug fit, thereby maximizing the seal between the seal and the container.

  While there are other embodiments that may incorporate some or all of the features outlined in the overview section, a number of specific container-sealer embodiments are described below by way of example only, with reference to the accompanying drawings. Explained.

[Detailed Description of Specific Embodiments]
Next, two embodiments (FIGS. 2 and 3) of the container-sealer structure will be described with reference to FIGS. Similar reference numerals are used to indicate similar or similar parts. Each structure generally includes a container in the form of a bucket 10 and a seal in the form of a lid 11. As shown in the figure, the structure is used for a circular bucket and lid, but these structures are equally applicable to square or rectangular buckets and lids.

  The bucket and lid can be molded from polypropylene or high density polyethylene. The bucket can be shaped to any desired dimensions and can have a volume on the order of 0.5 to 10 liters, for example. The bucket may also be formed from a metallic material. In addition, the lid-bucket structure is suitable for both containers with straight sides (FIG. 2) and containers with inclined walls (FIG. 3).

  The bucket 10 has a bottom 13 that is dimensioned so that it can be placed in a sealed portion of the lid. In this regard, the sealed portion has a substantially flat central region 14 so that the bottom of the overlying bucket can rest on the region 14 so that multiple bucket-lid structures are stacked in sequence. Can do. The bucket has an outer peripheral wall 15 with a rim 16 forming the upper edge of the wall 15 and surrounding the opening of the bucket.

  An outwardly projecting bead 17 is integrally formed with and surrounds the rim 16 and is spaced from the free upper end 16A of the rim. The bead 17 has a lower surface 18 extending from the outer surface 19 of the outer peripheral wall 15.

  An inwardly projecting bead 20 is integrally formed with the rim 16 and extends inwardly from its periphery, the bead 20 being defined as part of the free upper end 16A of the rim. The bead 20 has a lower surface 21 that extends from the inner surface 22 of the outer peripheral wall 15.

  By incorporating the bead spacing as shown and the bead 20 into the free upper end 16A of the rim, it becomes easier to remove the lid 11 from the container 10 (as described below).

  An annular container flange 24 can be integrally formed with the outer peripheral wall 15 of the container so as to surround it. The flange is located below the height of the bead 17 and thereby defines a circumferential groove 25 for receiving the skirt ledge (as will be described below). The flange is provided with a first wall portion 26 that is integrally formed with the outer surface 19 of the outer peripheral wall 15 and that extends outwardly from the outer wall 19 and surrounds it, and a second wall portion 27 that extends downward from the first wall portion 26. It has been. The wall portion 26 may be slightly inclined with respect to the outer peripheral wall 15 of the container or may be substantially perpendicular thereto.

  Flange 24 allows the lid to be attached to the container in a tamper-proof manner (as described below). Flange 24 also reinforces the bucket and provides resistance to side impacts and blows during transportation. In this regard, as best shown in FIGS. 2 and 3, since the flange 24 protrudes further to the side than the lid, it receives and absorbs preferentially impacts and blows, etc. Contributes to safe and secure installation of the lid when in use.

  The lid 11 may have a skirt 30 that surrounds the rim 16 when the lid is first attached to the bucket. The skirt 30 has a first skirt portion 32 and a second skirt portion 34, which is usually defined as a removable tear strip or band. The skirt may be formed as a continuous (uninterrupted) wall that hangs from the periphery of the lid and extends in the outer circumferential direction (for example, when the lid is permanently locked to the bucket, the structure is In most applications, the skirt is configured to be removable so that the lid can be easily opened. In this regard, the free strip end 34A (FIG. 1) can be defined as part of the second skirt portion 34, the free strip end 34A being the starting point where the hand can contact to cut and remove the strip. become. The strip end 34A can be shaped or formed to protrude slightly to allow easier contact. Alternatively, the skirt portion can be thinned, jagged, or scored at locations along the second skirt portion 34 to facilitate initiating removal of the cut strip.

  To assist in tamper-proofing the attachment of the lid to the bucket, when the lid is first attached to the bucket, the second skirt portion 34 extends downward to the flange 24 and closely faces the wall portion 26. (See FIGS. 2 and 3). This close-facing relationship (eg, abutment) provides a tamper-proof region between the lid and bucket and prevents the insertion of a knife or other sharp tool or blade between the lid and bucket. Can help you. However, even if such attempts are made, the close-facing relationship ensures that deformation or other breakage occurs, thereby indicating the tampering behavior visually or tactilely.

  The first skirt portion 32 is connected to the central region 14 by lands in the form of an annular bridge web 35, an inner wall 36 and a connecting web 37. The web 35 and wall 36 cooperate with the first skirt portion 32 to define an inverted U-shaped channel at a location adjacent to the central region 14 and house the rim 16 in the inverted U-shaped channel when the lid is attached to the bucket. To do.

  The second skirt portion 34 depends from the skirt portion 32 and is fragilely connected thereto by a thin connecting web 38 that is integrally formed. Alternatively, the web 38 can be defined by a cut line between the first and second skirt portions, which can be cut, for example, with a knife or torn apart.

  In both the embodiments of FIGS. 2 and 3, the second skirt portion has an inward protruding ledge 40 so that it engages and engages the bead 17 when the lid is first attached to the bucket as shown. Have In the embodiment of FIG. 2, the inner wall 36 has an inward protruding ledge 42 so that it engages and engages the bead 20 when the lid is attached to the bucket as shown. In the embodiment of FIG. 3, the web 35 has an inwardly protruding ridge 42 '(instead of the ledge 42) so that it engages and engages the bead 20 when the lid is attached to the bucket as shown. Have.

  Due to the double meshing engagement between the beads 17, 20 and the ledges 40, 42, once combined, the lid locks onto the bead on each side of the rim 16 and then the rim is locked into the U-shaped channel. Since the lid is fixed along its circumference, the lid can be securely and securely fastened to the bucket. Further, the intermeshing engagement of ledge 40 and bead 17 provides a “main” lock of the lid to the container. The expression “main” refers to an interlock that secures the lid to the bucket on the outside during transport and before loading and unloading the container contents. The intermeshing engagement of the ledge / ridge 42, 42 'with the bead 20 is called the "auxiliary" lock of the lid to the bucket, and this lock can re-fasten the lid to the bucket after the bucket contents have been taken in and out. Like that.

  For example, when the second skirt portion 34 is provided as a removable strip that can be cut along the web 38, removal of the portion 34 facilitates removal of the lid from the bucket. In addition, since the bead 20 is defined as part of the free upper end 16A of the rim, once the portion 34 has been removed, the lid ledge / ridge 42, 42 'is removed from the bead 20 and the lid is removed from the container 10. It becomes relatively easy to remove from. In this regard, after removing the portion 34, the lid 11 is then lifted so that the ridge 16 can be deflected outwardly because the first skirt portion is deflected or pressed outwardly, so that the ledge / ridge 42 , 42 ′ can be easily extruded beyond the bead 20.

  The first skirt portion 32 may also have a lid flange in the form of a protrusion 44 that extends outwardly from the periphery of the lid. The protrusion 44 has an outer shape that fits the finger of a person trying to lift the lid from the bucket after removing the second skirt portion 34. Alternatively, this lifting may be facilitated with a suitable tool. In any case, the lifting of the protrusions 44 can further facilitate outward deflection / pushing of the first skirt portion to further assist in the removal of the ledge / ridge 42, 42 'from the rim 16 and bead 20. .

  As shown, the second skirt portion 34 is positioned on the underside (or behind) of the bead (ie, snap-locked) once the ledge 40 has moved beyond the bead 17 while the lid is attached to the bucket. ) Have enough thickness to press. In this regard, the thickness and / or skirt material allows deformation of the second skirt portion during movement beyond the bead 17, but once in the position shown in FIGS. It is chosen to give sufficient elasticity to allow it to spring back.

  Beads 17 and 20 typically engage slidingly between the respective inner surfaces 46 and 47 of the second and first skirt portions and the surface 48 of the inner wall 36 (the embodiment of FIG. 2) when the lid is attached to the bucket. Easy to shape.

  In this regard, attachment of the lid to the bucket may be facilitated by placing a ring-shaped tool on the protrusion 44. The tool can have an inner diameter located on the protrusion 44 and abutting against the lid wall portion 35A, which extends from the web 35 and connects it to the protrusion 44. The user (or machine) can then press the ring tool to push the lid onto the bucket, the inner surfaces 46 and 47 slide past the bead 17, and the surface 46 is in the bead 20 (in the embodiment of FIG. 2). To slide over.

  As shown in both FIGS. 2 and 3, the protrusion 44 and the web 35 are connected by a wall portion 35A, thereby protruding from the intersection of the bottom 13 and wall 15 of the overlying bucket 10 ′. The outer peripheral flange 50 can be accommodated as shown. With this shape, such buckets can be stacked safely.

  With particular reference to FIG. 3, it will be appreciated that the lid stacking skirt 52 can be provided to extend from the underside of the lid 11. The skirt can extend from the annular bridge web 35 (as shown), but may extend from the inner wall 36 or the connecting web 37. The distal end 52A of the stacking skirt 52 can be received by an internal step 54 defined in the wall 15 of the container 10 when the lid is attached to the bucket. Thus, when stacking containers (eg, similar) containing one or more contents onto the lid 11, the stacking skirt 52 receives the mass of the container (s) containing the contents and To the step in the container wall, which then transmits this mass to its bottom. Thereby, the inward collapse of the lid in a loaded state can be prevented.

  Again, with particular reference to FIG. 3, it will also be seen that a sealing structure between the lid and the bucket can be used. In this regard, the seal structure can have one or more discontinuous lobes 56 or circumferential beads 56 disposed on (eg, integral with) the rim 16. In that case, the seal structure may further have one or more corresponding recesses 58 or circumferential grooves 58, respectively. Each recess or groove is defined in the first skirt portion 32 and is adapted to receive each lobe or bead therein, respectively, when the lid is attached to the bucket. Alternatively, each lobe or bead may be located in the first skirt portion 32 and each recess or groove may be located in the rim 16. In addition, each recess or groove and each lobe or bead can be dimensioned to produce an interference or sliding fit when engaged with each other. This further improves the sealing performance.

  In this way, the sealing structure provides a seal between the lid and the bucket, and in this regard, a gasket may be provided in that position, for example, to seal the bucket contents or to provide an additional hermetic seal. Good. The sealing structure further allows the first skirt portion 32 to be additionally clamped to the rim 16 (ie, once the second skirt portion 34 has been removed). This structure can be adapted as needed, i.e., once the skirt portion 34 is removed, for example, to reduce the main locking force.

  In use, after the container is filled and the lid is attached to the bucket, the second skirt portion 34 is removed (e.g., as a cut strip) when the user needs to move the bucket contents in and out, so that the ledge Remove 40 from bead 17. This releases the lid from its main lock position. The user then manually or using a suitable tool engages the protrusion 44 and lifts it from the bucket, thereby removing the ledge / ridge 42, 42 'from the bead 20 and the lid 11 Can be efficiently peeled back from the bucket 10 and the contents of the bucket can be taken in and out. After such access, the lid can be reinstalled by pushing the lid back onto the bucket until the ledge / ridge 42, 42 'engages and engages the bead 20, thereby sealing the bucket contents. Fix it and store it for later use.

  In the above embodiment, the lid is formed from a deformable and / or distortable material to facilitate attachment to and removal from the bucket. On the other hand, if necessary, the bucket may be formed of a deformable or non-deformable material such as plastic or metal.

  Although many embodiments have been described, it will be appreciated that the container-sealer structure can be embodied in many other forms.
