The present invention relates to the technical field of bags, in particular to a hard case type folding storage bag.
As we all know, satchels, handbags or backpacks are several bags often used in daily life to contain items.
However, an existing bag has many disadvantages: first, the bag usually does not have a waterproof and dustproof structure, such that the bag is easily affected with damp and polluted during use, and especially during outdoor use, a user puts the bag on the ground casually, and the situation that the bottom of the bag is affected with damp and polluted is unavoidable; secondly, the bag usually does not have a hard support structure, such that the bag is often placed unsteadily, resulting in tilting and untidy placement of the whole bag.
Therefore, based on long-term experience in production and manufacture of bags, the inventor conducts in-depth research on structures of the bags, and specially designs a hard luggage case type folding storage bag.
An objective of the present invention is to provide a hard case type folding storage bag, which not only may store items, but also has a special waterproof and dustproof structure, may be stably placed, and is convenient to fold and small in size after being folded.
To achieve the above objective, the present invention adopts the following solution:
A hard case type folding storage bag has a bag body and a hard bottom support, where the bag body is of a folding structure; the hard bottom support includes two symmetrical box covers; each of the box covers has a box bottom and a circle of support edge formed by extending upwards from a periphery of the box bottom, such that the box cover forms a sunken accommodating groove; the two box covers are arranged side by side, the accommodating grooves of the two box covers are open upwards, and the support edges of the two box covers are fixed to a bottom of the bag body, such that the bag body is supported on the two box covers when unfolded; the support edges of the two box covers are further mounted with zippers capable of being engaged with each other; and the two box covers are fastened together by zipping up to form a hard case, such that the bag body is hidden in the hard case after being folded.
Further, the two hard box covers are rectangular, two short edges of the two box covers are arranged side by side, and the two short edges adjacent to each other are pulled together through the zippers.
Further, an area of the two box covers arranged side by side is aligned with an area of a bottom of the bag body, such that the whole bottom of the bag body is located on the two box covers.
Further, reinforcing ribs are formed on the two box covers.
Further, arc-shaped transition guide corners are formed between the box bottoms and the support edges of the two box covers.
Further, a retaining ring is arranged on the support edge of one of the box covers.
Further, the hard bottom support is made of a hard plastic material.
Further, a side surface of the bag body is provided with a transverse baffle strip.
Further, the bag body is a satchel, a handbag, a backpack, a storage bag, a thermal bag, or a shoe bag.
With the above solution, the present invention has the following characteristics:
First, the bag body may keep an effect of storing items as always and is convenient to use.
Secondly, the hard bottom support is added to the bottom of the bag body, such that a special waterproof and dustproof structure is added. When the bag body is unfolded, the bottom of the bag body may be supported by the two box covers of the hard bottom support. When the bag is placed on the ground, the sunken accommodating grooves of the box covers support the bottom of the bag body to make the bottom of the bag body keep a sufficient distance from the ground, such that multiple effects of preventing water, moisture, and pollution may be achieved, and the cleanliness of the bag body may be ensured.
Thirdly, the hard bottom support itself prevents water, moisture and pollution, such that even if the hard bottom support gets dirty, it can be restored to cleanliness with a little wipe and thus is easy to clean.
Fourthly, the hard bottom support is added to the bottom of the bag body, and the sunken accommodating groove has a circle of the support edge, such that the support strength of the box cover is improved and the support effect is more stable. When the bag body is unfolded, the bag may be stably placed under the support of the hard bottom support, such that the whole bag is prevented from tilting and can be placed tidily.
Fifthly, the two box covers of the hard bottom support are fastened and fixed together to form the hard case, such that the bag body is hidden in the hard case after being folded. Therefore, the hard case is convenient for the bag to fold, making the folded bag very small in size and convenient to store and carry; moreover, the folded bag is protected by the hard case, such that the bag may be prevented from being scratched and damaged, and effective use in the subsequent process is ensured.
Sixthly, the unfolded bag may be stably placed on a top surface of a luggage case with support rods in cooperation with the hard bottom support, and the bag may be better fixed in a manner that the transverse baffle strip on the side surface of the bag body is sleeved on the support rods of the luggage case.
In short, the present invention has multiple functions of storage, folding, water, moisture and dust prevention, stable placement and the like, and the folded bag only has a size of a small box, occupies a small space, can contain a great number of products, and is low in transport cost and convenient to store.
The present invention is further described below with reference to the accompanying drawings and specific embodiments.
To make the objective, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some rather than all of the embodiments of the present invention.
It is to be noted that the terms “up”, “down”, “inside”, “outside”, “first”, “second”, etc. are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance or implying the indicated technical features, unless otherwise expressly specified.
As shown in
The bag body 1 is of a folding structure. Specifically, the bag body 1 may be a backpack, a handbag, a storage bag, a satchel, a thermal bag, or a shoe bag. The bag body 1 may keep an effect of storing items as always and is convenient to use. A side surface of the bag body 1 may be provided with a transverse baffle strip 11. When the bag body 1 is placed on a luggage case, the transverse baffle strip 11 may be sleeved on support rods of the luggage case, such that the bag can be conveniently transported with the luggage case.
The hard bottom support 2 includes two symmetrical box covers 21. The hard bottom support 2 may be made of a hard plastic material. Each box cover 21 has a box bottom 22 and a circle of support edge 23 formed by extending upwards from a periphery of the box bottom 22, such that the box cover 21 forms a sunken accommodating groove 24. According to optimized design, arc-shaped transition guide corners 25 are formed between the box bottoms 22 and the support edges 23 of the two box covers 21. Reinforcing ribs 26 are further formed on the two box covers 21, such that the strength and support force of the hard bottom support 2 are increased.
The two box covers 21 are arranged side by side, the accommodating grooves 24 of the two box covers 21 are open upwards, and the support edges 23 of the two box covers 21 are fixed to a bottom of the bag body 1, such that the hard bottom support 2 and the bag body 1 are combined together. According to the present invention, the hard bottom support 2 is added to the bag body 1, such that a special waterproof and dustproof structure is added. When the bag body 1 is unfolded, the bottom of the bag body 1 may be supported by the two box covers 21 of the hard bottom support 2. The sunken accommodating grooves 24 support the bottom of the bag body 1 to make the bottom of the bag body 1 keep a sufficient distance from the ground, such that multiple effects of preventing water, moisture, and pollution may be achieved, and the cleanliness of the bag body 1 may be ensured. Even if the hard bottom support 2 gets dirty, it can be restored to cleanliness with a little wipe and thus is easy to clean. Moreover, the sunken accommodating groove 24 has a circle of the support edge 23, such that the support strength of the box cover 21 is improved and the support effect is more stable. When the bag body 1 is unfolded, the bag may be stably placed under the support of the hard bottom support 2, such that the whole bag is prevented from tilting and can be placed tidily. Especially when the bag is placed on a top surface of the luggage case with the support rods, the bag may be better fixed in a manner that the transverse baffle strip 11 on the side surface of the bag body 1 is sleeved on the support rods of the luggage case. Compared with a general bag sleeved on the luggage case, the present invention is placed more stably, and the situation that the bag is tilting and unstable due to irregular items contained in the bag is avoided.
The support edges 23 of the two box covers 21 are further mounted with zippers 27 capable of being engaged with each other. The two box covers 21 may be fastened and fixed together by pulling up the zippers 27 to form a hard case. In this case, the bag body 1 is completely folded. Moreover, the completely folded bag body 1 may be hidden in the hard case, such that the whole bag according to the present invention is in a completely folded state. The folded bag is shaped like a small hard case (a small box), which occupies a small space, can contain a great number of products, and is low in transport cost and convenient to store. In short, the hard case according to the present invention is convenient for the bag to fold, making the folded bag very small in size and convenient to store and carry; moreover, the folded bag is protected by the hard case, such that the bag may be prevented from being scratched and damaged, and effective use in the subsequent process is ensured.
According to optimized design of the present invention, the two box covers 21 are rectangular, two short edges of the two box covers 21 are arranged side by side, and the two short edges adjacent to each other are pulled together through the zippers 27, such that the two box covers 21 are always connected together to form a stable big support block. In this way, the bag body 1 may be better supported after being unfolded.
According to optimized design of the present invention, an area of the two box covers 21 arranged side by side is aligned with an area of a bottom of the bag body 1, such that the whole bottom of the bag body 1 may be completely located on the two box covers 21, and the waterproof and dustproof effects and the support effect are better.
According to the present invention, a retaining ring 28 is arranged on the support edge 23 of one of the box covers 21. When the two box covers 21 are fastened to form the hard case, the whole bag is folded to the maximum extent. The bag may be conveniently hooked to any position by virtue of the retaining ring 28 for convenient use next time.
The above is only an example of implementation of the present invention and is not a limitation on the scope of protection of the present invention. It should be pointed out that equivalent changes made by those skilled in the art according to the design idea of the present invention upon reading this specification all fall within the scope of protection of the present invention.
