Description

  This invention relates to a foldable heat insulating cover.

  Conventionally, merchandise that has been transported in a storage case such as a folding container has been transferred to a cold bag every time it arrives at a store to prevent defective products. For this reason, there is a problem that the working time increases, the product deteriorates while waiting for transshipment, and defective products are generated.

  In addition, the baggage sorted into the foldable container is transported with a large sipper, resulting in a waste of space. In addition, because the space is too large, quality and temperature control has not been performed properly.

Therefore, for reference, patent documents related to heat insulation covers that have been filed so far are introduced. (See Patent Documents 1 to 4.)

  Therefore, in order to solve the above-described problems, the present invention is to develop and provide a foldable heat insulating cover that can be folded and stored by anyone and that has excellent cold or heat insulating properties.

  As means for solving this problem, it is a bottomless rectangular body having an upper surface and four side surfaces, and among the four side surfaces, the height dimension is less than half of the lateral width dimension, on the front side surface and the rear side surface, Each side is 45 degrees from the upper end of the horizontal width or at a functioning angle toward the lower center, and is provided in a substantially V shape with diagonal stitches that are fold lines, respectively. By sewing a locking member made up of a band and a band locking bracket or the like, easy folding storage is possible.

  As an effect of the present invention, a bottomless rectangular body having an upper surface and four side surfaces, the height dimension of which is less than half of the lateral width dimension, the front side surface and the rear side surface are both lateral widths. 45 degrees from the upper end or a functioning angle toward the lower center, with a diagonal stitch that becomes a fold line, and a substantially V-shape at the lower ends of the left and right sides. By sewing the locking members made of fasteners, etc., anyone can easily fold and store them, and work efficiency, safety, and economy, such as shortening work time and effective use of work space, etc. This is a very beneficial effect.

  The best form of this device is a cover structure that fits the size of the storage case used, can be folded easily and quickly by anyone, has excellent cold and heat retention properties, and is not easily damaged. It is important to do.

  Accordingly, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5, which is a cover that cools or keeps a product stored in a storage case such as a folding container, and the cover (1 ) Is a bottomless rectangular body having an upper surface and four side surfaces, and of the four side surfaces, the height dimension (H) is less than half of the width dimension (L), and the lateral widths on the front side surface and the rear side surface, respectively. It is provided so as to be substantially V-shaped with diagonal stitches (Sa) (Sa ′) that are fold lines, respectively, toward the lower center at 45 degrees or a functioning angle from the upper ends of the both ends. It is composed of a heat retaining cover that can be easily folded by sewing a locking member comprising a hook-and-loop fastener (F), a fastener-type band (FB), and a band locking metal fitting (K).

  Next, the details of this device will be explained. First, the structure of the cover (1) is made by superposing heat insulating materials between aluminum foils and stitching them together to form a box shape. The edges are reinforced by stitching together with thick cloth.

  As shown in FIG. 1, the upper surface of the cover (1) is provided with an opening / closing lid (4) with a handle (4a) and a storage port (1b) for containing the coolant (C). A net-like bag (5) is sewn, and water-absorbing pads (6) that can be fixed by two hook-and-loop fasteners (F) and (F) are provided on the top of the bag (5).

  The cover (1) is provided with lateral displacement prevention guide stoppers (2), (2), (3), and (3) that fit into the recesses on the bottom surface of the storage case (CO). In addition to this case, we are applying for a utility model registration application for this lateral displacement prevention guide stopper.

  In addition, the front and rear side surfaces of the cover (1) are inclined stitches (Sa) (Sa ') that are respectively fold lines toward the lower center at 45 degrees or a functioning angle from both upper ends of the width in order to facilitate folding. The hook-and-loop fastener (F) and the fastener-type band (FB) are provided so as to have a substantially V-shape or a shape similar to a substantially V-shape. Band locking brackets (K) are provided, respectively, and handles (7) and (7) at the time of removing the cover are provided at the upper ends of the left and right side surfaces, respectively.

  FIG. 6 is a plan view showing a procedure for folding the cover upside down. First, fold the front and rear side surfaces inward according to the substantially V-shaped fold line (FL), then The left and right side surfaces are folded inwardly, and finally fixed using a hook-and-loop fastener (F), a fastener-type band (FB), and a band locking metal fitting (K).

  Next, the method of using this device will be described. As shown in FIG. 7, a storage case (CO) containing products is placed on an underlay sheet, and a cover (1) is placed over the storage case (CO). ) Is placed, and the cover (1) is placed thereon. When the number of steps further increases, the same procedure as described above is performed. However, when stacking, the guide stoppers (2), (2), (3), and (3) for preventing lateral displacement provided on the four sides of the upper surface of the cover (1). The storage case (CO) is placed so that the recesses on the four sides of the bottom face are securely fitted. In addition, at the time of cold preservation, it may be necessary to put the coolant (C) in the bag (5) inside the cover (1) in advance.

  As another example, as shown in FIG. 8, the upper surface of the cover (1) does not have an opening / closing lid (4) for storing the coolant (C), a bag (5), and a water absorption pad (6). There is also a type in which a bag (8) is provided on the inner side of the cover. In addition, there is a type that does not require a coolant and therefore does not have a bag (8) when the cold insulation performance is not strongly required.

  The foldable heat insulation cover of this device can be folded and stored easily by anyone, and since it has excellent cold and heat insulation properties, it can be used industrially in terms of contributing to many food industries and transportation-related markets. Have
