Description
Technical Field
[0001] The utility model relates to the technical field of vacuum storage bags, in particular to a three-dimensional vacuum storage bag. Background Art
[0002] In real life, when the seasons change from spring to summer, every family uses vacuum compression bags to store quilts, clothes, pillowcases, blankets and other items. This can save about 75% of the storage space, and can also prevent moisture and mildew, and prevent the growth of bacteria.
[0003] Most existing vacuum compression bags consist of a composite bag with a closed front and open rear wall. A heat-sealed air valve is placed on the composite bag, and a double-open, double-closed, leak-proof zipper is placed at the opening. During use, the zipper is closed, and a vacuum pump is connected to the air valve to extract the air from the bag. Once the bag is nearly vacuum-free, the air valve is closed to prevent outside air from entering. Currently, with the improvement of people's quality of life, higher standards are being placed on the use of vacuum bags. Because vacuum bags are soft and irregular in shape, the shape of the object placed inside determines the state of the bag after vacuuming. Most clothing cannot be neatly arranged in a storage bag, making it difficult to stack neatly in a wardrobe or other place. Utility Model Content
[0004] In order to solve the technical problem that the above-mentioned vacuum bag is relatively soft and cannot form a regular shape after vacuuming clothes in it, the present technical solution provides a three-dimensional vacuum storage bag, in which the bottom of the vacuum bag is made into a lower bag body, and a supporting device is made on the side wall of the lower bag body; after the clothes are placed in the storage bag, the bottom can form a regular rectangular parallelepiped, and when it is placed in a wardrobe or other place, it can be stacked neatly; it can effectively solve the above-mentioned problem.
[0005] The utility model is achieved through the following technical solutions:
[0006] A three-dimensional vacuum storage bag comprises a vacuum bag body, a sealing device arranged at the top opening of the vacuum bag body, and an air valve arranged on the upper part of the vacuum bag body; the vacuum bag body comprises a three-dimensional lower bag body arranged at the bottom, and a front bag wall and a rear bag wall fixed at the top opening of the lower bag body, the tops of the front bag wall and the rear bag wall are fixedly connected to the sealing device; transparent windows are arranged on the side walls and / or the front bag wall and / or the rear bag wall of the lower bag body.
[0007] Furthermore, the lower bag body includes a bottom surface arranged at the bottom, and a plurality of sliced side walls fixed at the outer edge of the bottom surface; the outer edge of the bottom surface and the side walls, as well as the connection points of the plurality of sliced side walls are fixedly connected to form support strips.
[0008] Furthermore, pressed edge seals are provided between the bottom surface and the side walls of the lower bag body, between the side walls, at the fixing points between the top of the lower bag body and the front bag wall and the rear bag wall, and at the fixing points between the front bag wall and the rear bag wall.
[0009] Furthermore, the width of the pressed edge seal is 0.5 to 2 centimeters.
[0010] Furthermore, a plurality of supporting devices are fixed on the side wall of the lower bag body, located outside the transparent window.
[0011] Furthermore, the supporting device may be a plurality of tie bars fixed at intervals on the side wall, and the length of the tie bars is equal to or less than the height of the side wall of the lower bag body.
[0012] Furthermore, the supporting device may adopt a plurality of supporting plates fixed on the side walls, and the area of the supporting plates is less than or equal to half of the area of the side walls of the lower bag body.
[0013] Furthermore, the hardness of the material used for the tie bars or support plates is greater than the hardness of the material of the vacuum bag body.
[0014] Furthermore, the tie bars or support plates are made of polyester cloth or / and Oxford cloth or / and canvas or / and knitted cloth; and / or the vacuum bag body is made of a cloth-plastic composite material.
[0015] Furthermore, the vacuum bag body includes an inner film and an outer fabric; and / or the transparent window is made of a barrier transparent film; and / or the barrier transparent film is pressed onto the inner film layer at a designated position in the vacuum bag body. Beneficial effects
[0016] The three-dimensional vacuum storage bag proposed in this utility model has the following beneficial effects compared with the prior art:
[0017] The utility model forms a lower bag body at the bottom of the vacuum bag, which is then formed into a regular rectangular parallelepiped. A support device is provided on the side wall of the lower bag body. The support device props up the vacuum bag when clothing or bedding is placed, making it easier for people to place clothing or bedding. When people place clothing and bedding into the vacuum bag and fill the bottom of the vacuum bag, a regular cube is formed. The support device is made of a relatively hard fabric. When the vacuum bag is evacuated, the material of the support device is not too hard, providing a certain degree of support without damaging the vacuum bag itself. After evacuation, the bottom of the vacuum bag forms a relatively regular rectangular parallelepiped, allowing it to be neatly stacked when placed in a wardrobe or other place, thus meeting people's usage needs.
[0018] The utility model uses hot air pressing to press the connecting part into a heat-sealed edge. The heat-sealed edge not only has the effect of fixing and sealing, but also acts as a support bar through the reserved heat-sealed edge of 0.8 cm or more, which can provide a certain degree of support and stiffness when the vacuum storage bag is opened to place clothes and bedding inside. The hardness of the heat-sealed edge is also lower than that of conventional plastic or metal support bars. When the vacuum bag is vacuumed and folded for storage, because it is made of the same material as the vacuum bag body and is integrated with the vacuum bag body, it is easier to fold or deform with vacuuming, and will not cause damage to the vacuum bag body during vacuuming.
[0019] The transparent window of the utility model allows the approximate contents of the clothes placed in the vacuum bag to be observed after vacuuming, which facilitates later searching and sorting. BRIEF DESCRIPTION OF THE DRAWINGS
