[Solution] The inner layer fastener has a first tape and a second tape, and the first tape and the second tape each have a fixed end and teeth. The fixed end of the first tape is fixed to the inner surface of the first shell, and the fixed end of the second tape is fixed to the inner surface of the second shell. The interlining member has a first fixed end, a second fixed end and a connecting portion, the first fixed end is fixed to the first shell, and the second fixed end is fixed to the second shell. The connecting portion is positioned to span between the first annular opening edge and the second annular opening edge and shield the inner layer fastener. The distance between the first annular opening edge and the second annular opening edge 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 and the second annular opening edge when the teeth of the first tape and the teeth of the second tape are engaged.

Description

This invention relates to a carry bag with an expandable function, and more particularly to a carry bag with an expandable function having an internal zipper. Commercially available carry-on bags come in various types depending on their features. If you want to avoid damage to your belongings inside the bag, a shock-resistant carry-on bag is recommended. If you need to increase storage space depending on the amount of luggage you need to carry, a carry-on bag with an expandable function is recommended. Existing expandable carry-on bags have two exposed zippers. One zipper is used to open and close the two shells or front shell of the carry-on bag. The other zipper is used to expand the storage space of the carry-on bag. In addition, it is common to equip the exposed zippers on the carry-on bag with locks to prevent others from opening them without permission. However, when using a carry-on bag on a rainy day or in a humid environment, if moisture seeps into the storage space of the carry-on bag through the teeth on both sides of the zipper, the contents inside may absorb moisture and become unusable. Furthermore, carry-on bags with exposed zippers are relatively complex and not aesthetically pleasing, so there is room for improvement in existing carry-on bags. A relevant prior art document is Taiwan registration number TWM458136U. This is a perspective view showing an expandable carry bag with an internal zipper according to one embodiment of the present invention.This is a perspective view showing the expanded storage space in a carry bag with an expandable feature and an internal zipper according to one embodiment of the present invention.This is a plan view showing a cross-section along line A-A in Figure 1.This is a perspective view showing a section cut along line A-A in Figure 1.This is a plan view showing a cross-section along the line B-B in Figure 2.This is a perspective view showing a section cut along the line B-B in Figure 2. The following describes the expandable carry bag with an internal zipper according to the present invention, based on the drawings. Note that in this specification, the present invention and its scope of application are not limited to descriptions relating to materials and shapes, arrangement methods and the 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 direction in which they are normally used. (One embodiment) As shown in Figures 1 to 3, an expandable carry bag 1 with an internal layer 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 internal layer zipper 50, and a core member 60. The first shell 10 has opposing outer surfaces 101 and inner surfaces 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 surfaces 201 and inner surfaces 202, and a second annular opening edge 20a. The second annular opening edge 20a is defined from the second shell 20. As shown in Figures 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 extends outward from the first fitting portion 32 and to the outer surface 101 of the first shell 10. More specifically, the first fitting portion 32 has a first substrate 32a, a first retaining plate 32b, and a first connecting plate 32c. The first retaining plate 32b is parallel to the first substrate 32a and connected to the first shielding portion 34. The first connecting plate 32c is connected between the first substrate 32a and the first retaining 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 extends outward from the second fitting portion 42 and to the outer surface 201 of the second shell 20. More specifically, the second fitting portion 42 has a second substrate 42a, a second retaining plate 42b, and a second connecting plate 42c. The second retaining plate 42b is parallel to the second substrate 42a and connected to the second shielding portion 44. The second connecting plate 42c is connected between the second substrate 42a and the second retaining plate 42b. The inner layer fastener 50 consists of a first tape 52, a second tape 54, and a slider (not shown). The first tape 52 has opposing fixed ends 52a and teeth 52b. The second tape 54 has opposing fixed ends 54a and teeth 54b. The slider is fitted between the teeth 52b of the first tape 52 and the teeth 54b of the second tape 54. The teeth 52b and 54b interlock and separate as the slider operates. The core member 60 is composed of a first core 62 and a second core 64. The first core 62 has an
