Description

  The present invention relates to a heat insulating container such as a cooler box, in particular, a soft heat insulating container such as a soft cooler, and further to a liner attached to the inside of these heat insulating containers.

  Insulated containers, also called “cooler boxes”, are widely used and used in various activities. Larger cooler boxes are used in situations such as picnics and parties, but smaller cooler boxes are used in situations where an individual user keeps fewer items at a desired temperature.

  Current cooler box walls typically include a hard outer and inner shell and a thermally insulating central layer. The central layer is usually composed of a product having a high insulation value (R value). Although such hard coolers are convenient and popular, hard coolers are heavy and difficult to carry, and can be carried and stored even if the stored contents disappear and become empty. It is inconvenient to do. For this reason, the soft cooler provided with a soft wall part is spreading. The structure of such a soft cooler is already known, and the soft cooler is formed by a heat insulating material such as polystyrene foam wrapped with a flexible fabric such as polyester or nylon. A soft cooler is manufactured by covering one or more members of a thermal insulating material with a flexible material and sewing these members or parts of the members together to form a container. Soft coolers are lighter than hard coolers and can be easily folded and stored when not in use.

  Soft coolers are useful in this way, but users are looking for an insulated container that keeps the ice intact and, more importantly, does not allow water from melting the ice to leak from the seams. For this reason, it is desirable for the soft cooler to be provided with a water-resistant liner that fits snugly inside. In addition, the user can protect the contents contained in the cooler box to some extent from damage caused by deformation of the soft cooler itself, even if a heavy object is placed on the soft cooler or if it is accidentally stepped on. Seeking performance.

  Hard liners made of molded plastic are known. Hard liners provide water resistance and provide the desired structure for the soft cooler, but cannot be easily stored when not in use. For this reason, when the user folds the soft cooler, the hard liner needs to be removed from the soft cooler and stored separately. Note that the hard liner also has the advantage of being easy to clean.

  On the other hand, soft liners are also known and are generally stitched liners made from flexible polyvinyl chloride or polyethylene-vinyl acetate. The soft liner can be folded and easily stored, but the seam is not water resistant and cannot provide a sufficient structure for the soft cooler. In a liner that is not water resistant, the user is forced to use a cryogen rather than ice to avoid water leaking from the seam.

It is also within the scope of the present invention to use a strap using a hook and loop mechanism or other known securing means.

  As shown in FIGS. 9, 14, and 15, the liner 38 includes an integrally formed drainage body 70 that allows fluid to communicate between the inside and the outside of the liner 38. The drainage body 70 allows the melted ice, spilled liquid, and other substances to be easily removed from the inside of the liner 38 without lifting and tilting the liner 38 or the container 10 as a whole. The contents in 10 are prevented from spilling. As shown in FIG. 10, the through holes 72 are provided in the corresponding panels of the container 10 so as to be properly aligned with the drainage bodies 70 provided in the liner 38. This alignment allows fluid communication between the inside of the liner 38 and the outside of the container 10. The through hole 72 has a shape and a size suitable for the drainage spout 74. The drainage body 70 and the through hole 72 shown in the figure are provided in the liner 38 and the front panel 12 of the container 10, but as long as the drainage body 70 and the through hole 72 are properly aligned with each other, the back panel 14, the first or It can also be provided on the second end panel 16, 18 or the bottom panel 20. As shown in FIGS. 14 and 15, the drainage body 70 may have a normal structure, but in order to allow the drainage body 70 to selectively function and to remove liquid from the inside of the liner arbitrarily. It is preferable that a removable cover 76 is provided. Cover 76 is preferably removably secured to drainage spout 74 by a screw member, although other known means are within the scope of the present invention. It is also within the scope of the present invention that the drainage spout 74 comprises a known liquid dispenser.

  Also, as shown in FIGS. 14 and 15, in order to assist in maintaining the liner 38 in a fully expanded state during use, and to prevent the side wall of the liner 38 from being unintentionally folded, the liner 38 is used. Includes a sliding lock mechanism 80. In order to hold the sliding lock mechanism 80 on the liner upper edge 39 and to release the sliding lock mechanism 80 by applying a certain amount of force when desired, the liner 38 can be folded appropriately. A detent may be provided.

  FIGS. 13a to 13c show a mechanism for folding the container 10 and the liner 38 using the drainage body 70 and a function as means for holding the container 10 of the drainage body 70 in a folded state. When folding, all the contents of the liner and the container (not the liner itself) are removed, and preferably the liquid remaining from the drainage body 70 is drained. In order to fold the liner 38, the sliding lock mechanism 80 is slid to one corner of the liner upper edge 39. Thereafter, as shown in FIG. 13a, the container 10 is folded in the front-rear direction (horizontal direction, not vertical direction). The cover 76 is removed from the drainage spout 74 and the end of the drainage spout is exposed. When the container 10 is almost folded, the top panel 26 is overlaid on the front panel 12 of the container 10. The top panel 26 may further include a lip 27, but the lip 27 is not essential. Regardless of the presence or absence of the lip 27, a through hole 78 having a shape and a size adapted to the drainage spout 74 is provided at the front edge of the top panel 26. By positioning the through hole 78 on the drainage spout 74 and returning the cover 76 onto the drainage spout 74, the container 10 is held in a folded state. It is also within the scope of the present invention to use fixing means other than the through-hole 78 to hold the container 10 in a folded state.

  When the liner 38 is fully expanded from the fully expanded state, the first and second end panels 44 and 46 are folded inwardly as shown in FIG. 6, or as shown in FIG. The bottom panel 48 can be folded upward (or downward), and the front panel 40 and the back panel 42 are closer to each other than when the liner is expanded. It is possible to move.

A preferable method for producing the liner of the present invention is to cut a single sheet so that the pattern shown in FIG. 5 is obtained using a die-cut piece made of hard plastic. When using a hinge, it cuts so that the material located along seam _S1-15 may become thinner than panels other than a seam. The sheet is then folded and assembled into an expanded liner 38, and the open end of the seam is welded to complete the liner 38.

  In the case of a structure with a flexible hinge, the individual panels are separated from the sheet and placed in another mold, and a second material having higher flexibility is added to the hard panel and cured. The flexible material is located at each seam to form a flexible hinge, and the rigid panels are connected along the seam S to form the expanded liner 38 in a desired shape. Or although it is set as the structure provided with the flexible hinge, the structure which makes an end panel piece a single panel at least by connecting a plurality of end panel pieces mutually with a tab (not shown) can also be adopted, Such a structure is also within the scope of the present invention. The tab is made of the same material as the end panel, but is formed to be thinner. The tab assists in holding the end panel pieces in the proper position and orientation as the flexible material is added and cured.

  The container 10 may further have the general features of a cooler box. For example, the container 10 may have additional structures such as pockets, carabiner, additional handles. Alternatively, in the above description, a soft cooler is used for explanation, but the present invention can also be applied to a hard cooler. Moreover, fasteners other than a zipper can also be used. For example, a hook loop fastener can be used instead of a zipper. In addition, the container 10 can include one or more zippers and other fasteners.

In another embodiment shown in FIGS. 8 and 9, the container 10 has a similar general configuration with a flexible material at the seam, as described above, but the seam is a rigid material portion. On the other hand, it is wider. Further, as shown in the drawing, the joints S ₆ and S ₇ extend on the end panels 44 and 46 only between the end panels 44c and 44d and a part between the end panels 46c and 46d. In this embodiment, there are no triangular end panel pieces 44a, 44b, 46a, 46b. In the region where the panels 44a, 44b, 46a, 46b were present in FIGS. 1 and 5, the flexible material is present in FIG. As can be seen from FIG. 8, the seams S ₈ , S ₉ , S ₁₀ , S ₁₁ do not exist, and the seams S ₄ , S ₅ are triangular, and in FIGS. 1 and 5, the panels 44a, 44b, 46a, It exists in the area | region where 46b existed.

  Other embodiments are also within the scope of the idea of the present invention. That is, although the present invention may take various modifications and alternative constructions, specific embodiments of the present invention have been shown and described in detail above. However, the present invention is not limited to the embodiments disclosed above, and conversely, all modifications, alternative structures, and equivalents that fall within the spirit and scope of the present invention as defined in the appended claims. Configurations are understood to be included in the present invention. For example, the container 10 can function as a foldable liner that is detachably inserted into the soft cooler. On the other hand, the container 10 can be used as an independent container, or can be used in an outer container other than the soft cooler.
