Description

The present invention relates to a carry bag with expandable functions, and more specifically to a carry bag with expandable functions that has an inner line zipper.

There are many different types of carrier bags available on the market, depending on their functions. If you want to avoid damaging the contents inside the carrier bag, a shock-resistant carrier bag is recommended. If you want to be able to increase the storage space depending on the amount of storage, a carrier bag with an expandable function is recommended.

Existing carry bags with expandable functions have two strip zippers exposed to the outside. One strip zipper is for opening and closing the two shells or the front shell of the carry bag. The other strip zipper is for expanding the storage space of the carry bag. In addition, in order to prevent others from opening the strip zipper exposed to the outside of the carry bag, a lock is generally provided on the strip zipper. However, when the carry bag is used on a rainy day or in a humid environment, if moisture enters the storage space of the carry bag through between the teeth on the left and right of the strip zipper, the luggage in the storage space may absorb the moisture and become unusable. In addition, the appearance of the carry bag with the strip zipper exposed to the outside is relatively complicated and not beautiful, so there is room for improvement in the existing carry bags.

In view of the above-mentioned shortcomings, the main objective of the present invention is to provide a carry bag with an expandable function, in which a fastener for expanding the storage space is arranged on the inner layer of the carry bag, the structure for responding to the expansion of the storage space is provided with anti-theft and waterproof protection functions, and the bag has a simple appearance.

In order to solve the above-mentioned problems, a carry bag with an expandable function and an inner line fastener comprises a first shell, a second shell, a first annular guard member, a second annular guard member, an inner line fastener, and an interlining member. The first shell has an outer surface, an inner surface, and a first annular opening edge portion. The second shell has an outer surface, an inner surface, and a second annular opening edge portion. The first annular guard member is attached to the first annular opening edge portion. The second annular guard member is attached to the second annular opening edge portion. The inner line fastener has a first tape and a second tape. The first tape and the second tape each have a fixed end and a teeth. The fixed end of the first tape is directly fixed to the inner surface of the first shell or is fixed to the inner surface of the first shell by the first annular guard member. The fixed end of the second tape is directly fixed to the inner surface of the second shell or is fixed to the inner surface of the second shell by the second annular guard member. The teeth of the first tape and the teeth of the second tape can be engaged or disengaged. The interlining member has a first fixed end, a second fixed end, and a connecting portion located between the first fixed end and the second fixed end. The first fixed end is fixed directly to the first shell or fixed to the first shell by a first annular guard member. The second fixed end is fixed directly to the second shell or fixed to the second shell by a second annular guard member. The connecting portion is positioned to straddle between the first annular opening edge portion and the second annular opening edge portion to shield the inner layer fastener. The distance between the first annular opening edge portion and the second annular opening edge portion when the teeth of the first tape and the teeth of the second tape are separated is greater than the distance between the first annular opening edge portion and the second annular opening edge portion when the teeth of the first tape and the teeth of the second tape are engaged.

Due to the above-mentioned structural features, the inner line zipper is attached to the inside of the expandable carry bag and is shielded and protected by the first annular guard member, the second annular guard member and the interlining member, so that the expandable carry bag has the function of expanding the storage space. In addition, since the inner line zipper is not exposed, not only cannot the inner line zipper be opened from the outside of the expandable carry bag, but also the appearance of the expandable carry bag can be simplified.

In a relatively preferred case, the fixed end of the first tape is indirectly fixed to the inner surface of the first shell by the first annular guard member. The fixed end of the second tape is indirectly fixed to the inner surface of the second shell by the second annular guard member. Due to the above-mentioned structural features, when the first tape and the second tape of the inner layer line fastener are damaged, the first tape and the second tape can be removed from the first annular guard member and the second annular guard member and replaced. By fixing the first annular guard member and the first tape to the first shell by sewing or another fixing method, the efficiency of the assembly work can be improved.

In a relatively preferred embodiment, the first fixed end of the interlining member is indirectly fixed to the outer surface of the first shell by a first annular guard member. The second fixed end of the interlining member is indirectly fixed to the outer surface of the second shell by a second annular guard member. Due to the above-mentioned structural features, when the interlining member is damaged, the interlining member can be replaced by separating the first fixed end from the first annular guard member and the second fixed end from the second annular guard member.

In a relatively preferred case, the first fixed end of the interlining member is indirectly fixed to the outer surface or inner surface of the first shell by the first annular guard member. The second fixed end of the interlining member is indirectly fixed to the outer surface or inner surface of the second shell by the second annular guard member. Due to the above-mentioned structural features, when the interlining member is damaged, the interlining member can be replaced by separating the first fixed end from the first annular guard member and the second fixed end from the second annular guard member. In addition, the efficiency of the assembly work can be improved by separately fixing the first fixed end and the second fixed end of the interlining member to the first annular guard member and the second annular guard member by sewing or another fixing method, and separately fixing the first annular guard member and the second annular guard member to the first shell and the second shell.

In a relatively preferred case, the first annular guard member has a first fitting portion and a first shielding portion. The first fitting portion is fitted and fixed to the edge of the first annular opening of the first shell. The first shielding portion is disposed extending outward from the first fitting portion to the outer surface of the first shell. The second annular guard member has a second fitting portion and a second shielding portion. The second fitting portion is fitted and fixed to the edge of the second annular opening of the second shell. The second shielding portion is disposed extending outward from the second fitting portion to the outer surface of the second shell. The inner layer line fastener has a fixed end of the first tape fixed to the first fitting portion and a fixed end of the second tape fixed to the second fitting portion. The first fixed end of the interlining member is fixed to the first fitting portion and shielded by the first shielding portion. The second fixed end of the interlining member is fixed to the second fitting portion and shielded by the second shielding portion. Due to the above-mentioned structural features, when the first fitting portion is fitted to the edge portion of the first annular opening and the second fitting portion is fitted to the edge portion of the second annular opening, and the first and second annular guard members are damaged, the first and second annular guard members can be removed from the edge portion of the first annular opening and the second annular guard member can be removed from the edge portion of the second annular opening and replaced. The first and second shielding portions can shield the joints between the first and second fixed ends of the interlining member and the first and second fitting portions, protecting the interlining member.

In a relatively preferred embodiment, the first mating portion has a first substrate, a first pressure plate, and a first connecting plate. The first pressure plate is connected to the first shielding portion while being parallel to the first substrate. The first connecting plate is connected between the first substrate and the first pressure plate. The fixed end of the first tape of the inner layer line fastener is fixed to the inner surface of the first substrate. The first annular opening edge portion is fitted and fixed between the first substrate and the first pressure plate. The second mating portion has a second substrate, a second pressure plate, and a second connecting plate. The second pressure plate is connected to the second shielding portion while being parallel to the second substrate. The second connecting plate is connected between the second substrate and the second pressure plate. The fixed end of the second tape of the inner layer line fastener is fixed to the inner surface of the second substrate. The second annular opening edge portion is fitted and fixed between the second substrate and the second pressure plate. The above-mentioned structural features not only facilitate the installation and removal of the first mating portion, second mating portion, first annular guard member, and second mating member, but also allow the fixed end of the first tape of the inner layer line fastener to be firmly fixed to the inner surface of the first substrate of the first mating portion, and the fixed end of the second tape of the inner layer line fastener to be firmly fixed to the inner surface of the second substrate of the second mating portion.

In a relatively preferred embodiment, the interlining member has a first interlining and a second interlining. The first interlining and the second interlining each have an outer surface and an inner surface. The first interlining has a first fixed end and a first connecting end that face each other of the interlining member. The second interlining has a second fixed end and a second connecting end that face each other of the interlining member. The outer surface of the first connecting end and the outer surface of the second connecting end are in close contact with each other to connect the first connecting end and the second connecting end. Due to the above-mentioned structural features, when the interlining member is folded and stored, the outer surface of the first interlining overlaps the outer surface of the second interlining and is stable.

In a relatively preferred case, when the teeth of the first tape of the inner layer fastener and the teeth of the second tape mesh with each other, the first interlining of the interlining member is in close contact with the first connecting plate of the first fitting portion. The first connecting end of the first interlining and the second connecting end of the second interlining are folded and stored between the inner surface of the first board of the first fitting portion and the outer surface of the first tape of the inner layer fastener. In other words, the interlining member can be folded and stored in a specified space.

The following describes the expandable carry bag with an inner line zipper according to the present invention with reference to the drawings. In the specification, the present invention and its scope of application are not limited to descriptions related to materials and shapes, arrangement methods and number of parts, technical terms and directional terms. Directional terms such as up and down, left and right, top, bottom, inside and outside are expressed based on the directions normally used.

(One embodiment)
As shown in Figures 1 to 3, an expandable carry bag 1 having an inner line zipper according to one embodiment of the present invention comprises a first shell 10, a second shell 20, a first annular guard member 30, a second annular guard member 40, an inner line zipper 50 and an interlining member 60.

The first shell 10 has opposing outer and inner surfaces 101 and 102, and a first annular opening edge 10a. The first annular opening edge 10a is defined from the first shell 10. The second shell 20 has opposing outer and inner surfaces 201 and 202, and a second annular opening edge 20a. The second annular opening edge 20a is defined from the second shell 20.

3 to 6, the first annular guard member 30 is integrally molded from plastic and has a first fitting portion 32 and a first shielding portion 34. The first shielding portion 34 is arranged to extend from the first fitting portion 32 to the outside and to the outer surface 101 of the first shell 10. In particular, the first fitting portion 32 has a first base plate 32a, a first pressing plate 32b, and a first connecting plate 32c. The first pressing plate 32b is parallel to the first base plate 32a and connected to the first shielding portion 34. The first connecting plate 32c is connected between the first base plate 32a and the first pressing plate 32b. The second annular guard member 40 is integrally molded from plastic and has a second fitting portion 42 and a second shielding portion 44. The second shielding portion 44 is arranged to extend from the second fitting portion 42 to the outside and to the outer surface 201 of the second shell 20. In particular, the second fitting portion 42 has a second base plate 42a, a second pressing plate 42b, and a second connecting plate 42c. The second pressing plate 42b is parallel to the second base plate 42a and connected to the second shielding portion 44. The second connecting plate 42c is connected between the second base plate 42a and the second pressing plate 42b.

The inner layer fastener 50 is composed of a first tape 52, a second tape 54, and a slider (not shown). The first tape 52 has an opposing fixed end 52a and a tooth 52b. The second tape 54 has an opposing fixed end 54a and a tooth 54b. The slider is attached between the tooth 52b of the first tape 52 and the tooth 54b of the second tape 54. The tooth 52b and the tooth 54b mesh with and separate from each other by the operation of the slider.

The interlining member 60 is composed of a first interlining 62 and a second interlining 64. The first interlining 62 has an outer surface 621 and an inner surface 622. The second interlining 64 has an outer surface 641 and an inner surface 642. More specifically, the first interlining 62 has a first fixed end 62a and a first connecting end 62b facing each other. The second interlining 64 has a second fixed end 64a and a second connecting end 64b facing each other. The outer surface 621 of the first connecting end 62b and the outer surface 641 of the second connecting end 64b are in close contact with each other to connect the first connecting end 62b and the second connecting end 64b. The interlining member 60 further has a connecting portion 66. The connecting portion 66 is located between the first fixed end 62a of the first interlining 62 and the second fixed end 64a of the second interlining 64. When the installation work is performed, the first fixed end 62a of the first interlining 62 is fixed to the outer surface of the first pressing plate 32b of the first fitting portion 32 by sewing and is shielded by the first shielding portion 34. The second fixed end 64a of the second interlining 64 is fixed to the outer surface of the second pressing plate 42b of the second fitting portion 42 by sewing and is shielded by the second shielding portion 44. The fixing method of the first fixed end 62a of the first interlining 62 to the first pressing plate 32b of the first fitting portion 32 and the fixing method of the second fixed end 64a of the second interlining 64 to the second pressing plate 34b of the second fitting portion 42 are not limited to this embodiment, and adhesive members, buttons, or other fastening methods may be used.

3 and 4, in this embodiment, the first annular guard member 30 is attached to the first annular opening edge portion 10a of the first shell 10. More specifically, the first annular opening edge portion 10a is fitted and fixed between the first substrate 32a and the first pressing plate 32b of the first fitting portion 32. The fixed end portion 52a of the first tape 52 of the inner layer line fastener 50 and the first substrate 32a of the first annular guard member 30 are fixed together to the first annular opening edge portion 10a of the first shell 10 by sewing. At this time, the first annular opening edge portion 10a is in close contact with the outer surface 32a1 of the first substrate 32a. The fixed end portion 52a of the first tape 52 of the inner layer line fastener 50 is in close contact with the inner surface 32a2 of the first substrate 32a. In other words, in this embodiment, the fixed end 52a of the first tape 52 of the inner layer line fastener 50 is fixed to the inner surface 102 of the first shell 10 by the first annular guard member 30, so that the first tape 52 of the inner layer line fastener 50 is located inside the first shell 10. However, this embodiment is not limited to the method of fixing the first annular guard member 30 and the first tape 52 of the inner layer line fastener 50 to the first shell 10, and a method of directly fixing the fixed end 52a of the first tape 52 of the inner layer line fastener 50 to the inner surface 102 of the first shell 10 may be adopted. In addition, the first annular guard member 30 allows the first fitting portion 32 to be smoothly attached and detached to the first annular opening edge portion 10a. In detail, when the first annular guard member 30 or the first tape 52 of the inner layer line fastener 50 is damaged, the first annular guard member 30 can be removed from the first annular opening edge portion 10a or the first tape 52 of the inner layer line fastener 50 can be removed from the first annular guard member 30 to proceed with the replacement work. The first annular guard member 30 and the second annular guard member 40 are arranged symmetrically. In other words, as shown in the figure, the relative positional relationship between the first annular guard member 30 and the first annular opening edge portion 10a, and the assembly of the first annular guard member 30, the first shell 10, and the first tape 52 of the inner layer fastener 50 are symmetrical to the relative positional relationship between the second annular guard member 40 and the second annular opening edge portion 20a, and the assembly of the second annular guard member 40, the second shell 20, and the second tape 54 of the inner layer fastener 50.

As shown in Figures 3 to 6, after the assembly work is completed, the connecting portion 66 of the interlining member 60 is positioned so as to straddle the first annular opening edge portion 10a and the second annular opening edge portion 20a and shield the inner layer fastener 50. When the teeth 52b of the first tape 52 and the teeth 54b of the second tape 54 are separated by the operation of the slider of the inner layer fastener 50 to maintain the expanded state (see Figure 6), the distance D2 between the first annular opening edge portion 10a and the second annular opening edge portion 20a is larger than the distance D1 between the first annular opening edge portion 10a and the second annular opening edge portion 20a when the teeth 52b of the first tape 52 and the teeth 54b of the second tape 54 are engaged to maintain the stored state (see Figure 4). In other words, by expanding or folding the interlining member 60 by the operation of the slider of the inner layer fastener 50, the storage space of the expandable carry bag 1 can be expanded or returned to its original state.

In this embodiment, the expandable carry bag 1 further has a front lid or a front pocket (not shown in the figure). The front lid or the front pocket can be opened and the slider of the inner line zipper 50 inside the expandable carry bag 1 can be pulled to maintain the expandable carry bag 1 from its original state (see Figures 3 and 4) to its expanded state (see Figures 5 and 6). The structure of the front lid and the front pocket has been disclosed in the prior art (e.g. Taiwan Utility Model Registration Publication No. M559646), so a detailed description will be omitted.

In this embodiment, the interlining member 60 is composed of two units, namely, a first interlining 62 and a second interlining 64. The first interlining 62 and the second interlining 64 are connected to each other by sewing together the outer surface 621 of the first connecting end 62b and the outer surface 641 of the second connecting end 64b, which are in close contact with each other. Due to the above-mentioned structural features, when the slider of the inner layer line fastener 50 is pulled to engage the teeth 52b of the first tape 52 with the teeth 54b of the second tape 54, the connection portion 66 of the interlining member 60 is folded, i.e., the outer surface 621 of the first interlining 62 overlaps the outer surface 641 of the second interlining 64. 3 and 4, when the folded portion of the interlining member 60 is fitted between the inner surface 32a2 of the first substrate 32a of the first fitting portion 32 and the outer surface of the first tape 52 of the inner layer line fastener 50, the entire interlining member 60 is folded and shielded by the first shielding portion 34 and the second shielding portion 44. The structure of the interlining member 60 is not limited to this embodiment, and even a single structure can perform the same function as the interlining member 60 consisting of two units. Compared to a single structure interlining member, the interlining member 60 consisting of two units is not only easier to fold, but is also relatively convenient when combined with another unit.

In this embodiment, the first tape 52 and the second tape 54 of the inner layer fastener 50, which are shielded and protected by the interlining member 60, the first annular guard member 30, and the second annular guard member 40, are made of a waterproof material, so that on rainy days or in humid environments, moisture will not penetrate into the interior of the expandable carry bag 1 through between the teeth 52b of the first tape 52 and the teeth 54b of the second tape 54 of the inner layer fastener 50. In other words, there is no possibility that the luggage inside the expandable carry bag 1 will absorb moisture and become unusable.

In summary, in the expandable carry bag 1 according to the present invention, the inner line zipper 50 is attached inside the first shell 10 and the second shell 20 of the expandable carry bag 1 and is shielded and protected by the first annular guard member 30, the second annular guard member 40 and the interlining member 60, so that it can perform the function of expanding the storage space. In addition, since the inner line zipper 50 is not exposed to the outside and cannot be opened from the outside of the expandable carry bag 1, it performs anti-theft and waterproof protection functions and can simplify the appearance of the expandable carry bag 1.

The present invention is not limited to the above-mentioned embodiment, and can be implemented in various forms without departing from the spirit of the invention.
