Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Fig. 1a to 2b show a collapsible or storage-type bathtub 1 according to a first and a second embodiment of the present invention, respectively, the frame and the bottom of which are identical in shape and size, differing only in the side wall between the frame and the bottom. As shown, the tub 1 includes an outer frame 2, collapsible or extendable side walls 3, and a tub bottom 4. The outer frame 2 substantially defines the shape of the entire bathtub 1. The hollow portion of the outer frame 2 is an opening 5 having a substantially rectangular shape. The outer frame 2 may be injection molded by a hard plastic such as polypropylene (polypropylene) and have a certain rigidity. The outer frame 2 may be formed in the form of a groove to enhance the rigidity thereof.

As shown in fig. 1a to 2b, the inner edge portion of the outer frame 2 is closely coupled to the upper edge 3a of the foldable or extendable side wall 3. The side wall 3 may be injection moulded from a mass of thermoplastic elastomer TPE and formed integrally. Based on the materials adopted above, the side wall 3 has certain softness and elasticity. The lower edge 3b of the side wall 3 is tightly connected to the tub bottom 4, thereby forming a container for containing liquid in the collapsible tub 1.

Further, the side wall 3 has a plurality of folded portions 3 c. The plurality of folded portions 3c extend transversely along the side wall 3 and encircle the entire side wall 3. Each folded portion 3c is separated by a distance D as shown in fig. 1 b. The number of foldable layers of the bathtub 1 of the collapsible type depends on the number of the folded portions 3 c. Fig. 1a and 1b show an embodiment with a single folded layer. For this embodiment, the side wall 3 has two folded portions 3 c. While fig. 2a and 2b show an embodiment with two folded layers, the side wall 3 has four folded portions 3 c. In summary, the side wall 3 is folded by folding most of the side wall 3 along the folding portion 3c in a corrugated manner, so as to form a volume reduction effect. After folding, the side walls 3 are flat and very compact, as shown in fig. 3.

Thus, the side walls 3 can realize a greater volume of the tub 1 in more folded layers without changing the structure and size of the outer frame 1 and the tub bottom 4. It follows that the capacity of the collapsible bathtub 1 described above may depend on the number of folded layers and the distance D separating the two folded portions 3 c.
