The feeding device may be transparent or translucent. It also may be with color or without color. The feeding device 100 includes a circular base 1 and a sac 2 extending down from the said circular base 1. The sac 2 can be used to store food and for feeding a baby. Food is placed into the sac 2 through the open end of the circular base 1, and the sac can then be closed by a closure, e.g., elements 200 and 400 as in FIGS. 13-15. The sac 2, the sac 2 includes a bulbous end portion 21 having a maximum diameter at an intermediate location 4. For the feasibility of feeding via the sac 2, the bulbous end portion 21 is provided with a plurality of apertures 211 for the passage of food from the interior to the exterior of the bulbous end portion. These apertures include apertures above said intermediate location of the maximum diameter of the bulbous end Portion and apertures below said intermediate location of the maximum diameter of the bulbous end portion. The apertures 211 may be in any shape. To comfort and pacify the baby teeth, the sac may be set one or more protrusions (not shown) beside the apertures 211 or between apertures 211.
The sac 2 of the said feeding device 100 includes a collapsible part 22. The said collapsible part 22 is located at the end of sac 2 near to circular base 1 as one preferable embodiment. the said collapsible part 22 includes a plurality of spaced apart annular protrusions 221 and annular recesses 222. The said collapsible part 22 may be collapsed with extra force due to the design of plurality of spaced apart annular protrusions 221 and annular recesses 222 and the resilient material used. That is, the said annular recesses 222 are compressed and the said annular protrusions 221 are folded together.
To make the said collapsible part 22 easier to be folded, preferably, the thickness of the said annular protrusions 221 on the sac 2 may be thicker than that of the said annular recesses 222. It can be understandable that the thickness of the said annular protrusions 221 is same as that of the said annular recesses 222.
In this example instance, the thickness of the said annular recesses 222 of the collapsible part 22 is about from 0.4 to 0.7 times of that of other part of the sac 2 except the collapsible part 22. For example, the thickness of the sac is 1.2 mm, then the thickness of the said annular recesses 222 is 0.6 mm or 0.8 min or other like value.
In this example instance, the feeding device 100 is a three-folding feeding device. The collapsible part 22 of the sac 2 contains three spaced apart annular protrusions 221 and three annular recesses 222.

The annular protrusions and annular recesses are disposed in a series and in symmetrical relationship to a common axis 223. Each of the annular recesses of the sac, except for an annular recess closest to the circular base 1, is axially farther than a next preceding annular recess in the series from the circular base, with reference to the common axis 223.
With the collapsible part 22, in the one hand, the volume of the sac 2 is enlarged to store more food in it; on the other hand, the collapsible part 22 may function as pump so the user is easier to squeeze the food out for feeding. Furthermore, the collapsible part 22 may bend an angle to improve the usability and practicability. In this embodiment, the said collapsible part 22 is in gradual contraction shape from top to bottom. To be understandable, the said collapsible part 22 may be other type of shape, such as cylindrical shape from top to bottom.
This inventive feeding device may be used independently. It may also be integrated with other parts to form a feeding apparatus. To make the feeding device 100 feasible to match with other parts, in this embodiment, the feeding device 100 further includes a connection part 3 extended up from the said circular base 1. The said connection part 3 includes a circular connection piece 31 and a circular groove 32 which is formed between the said circular connection piece 31 and the said circular base 1.

For example, the circular connection piece 31 may be clamped by other parts so that the feeding device is connected with other parts.
As in FIG. 6 to FIG. 10, it is the second embodiment of the feeding device of this invention. The feeding device 100A is a four-folding feeding device. The structure of feeding device 100A is similar to that of feeding device 100 in the first embodiment except the collapsible part 22A of the sac 2A contains four spaced apart annular protrusions 221A and three annular recesses 222A. There is no repeat here. As showed in FIG. 9, the cross-section shape of the annular recesses 222A is in arc shape. As showed in FIG. 10, the cross-section shape of the annular recesses 222A′ is in wedge shape. That is the annular recess 222A′ is angular. Other labels in the figures are defined as: circular base 1A, sac 2A, the end 21A of the said sac 2A, apertures 211A, connection part 3A, circular connection piece 31A, and circular groove 32A.
As in FIG. 11 to FIG. 12, it is the third embodiment of the feeding device of this invention. The structure of feeding device 100B is similar to that of feeding device 100 in the first embodiment except the structure of the circular connection piece 31B is different from that of the said circular connection piece 31 in the first embodiment. In this embodiment, the outer peripheral of the said circular connection piece 31B has two notches for quickly positioning it with other parts. There is no repeat here to describe other structures. Other labels in the figures are defined as: circular base 1B, sac 2B, the end 21B of the said sac 2B, apertures 211B, connection part 3B, circular connection piece 31B, circular groove 32B, collapsible part 22B, annular protrusions 221B and annular recesses 222B.
