The disposable baby bottle of this disclosure includes a cap unit having a nipple and a cap and a first fastening portion at its lower end, a first body section connected to the cap unit, and a second body section connected to the first body section, wherein when the first body section and the second body section are disengaged, the first body section can be longitudinally fitted into the second body section.

Description

Technical Field

[0001] The present disclosure relates to a disposable feeding bottle, and more particularly to a disposable feeding bottle that can adjust the overall length of the body, which is convenient for carrying and using when going out.

Background Art

[0002] Generally, since a general feeding bottle needs to be washed after use for reuse, when going out with an infant, many people prefer a disposable feeding bottle that does not require cleaning.

[0003] A disposable feeding bottle incorporates a disposable vinyl pack for holding milk or breast milk for bottle feeding inside. Also, in a disposable feeding bottle, since only the vinyl pack needs to be discarded after bottle feeding, the disposable feeding bottle can be reused without separately cleaning it.

[0004] Therefore, a disposable feeding bottle is used conveniently and hygienically when one or more bottle feedings are required when going out.

[0005] Also, in a general feeding bottle, when going out with an infant for a long time, it is necessary to carry several feeding bottles in a bag, which is a burden. However, in a disposable feeding bottle, only a few vinyl packs need to be carried, so the luggage capacity can be reduced.

[0006] Therefore, in the feeding bottle for infants, the demand for disposable feeding bottles that do not require cleaning and are very convenient for use and carrying when going out has increased significantly, and various disposable feeding bottles have been developed to meet this demand.

[0007] Korean Utility Model Publication No. 20-2019-0001679 (July 3, 2019) discloses a disposable plastic pack for baby bottles, intended to be connected inside the baby bottle. According to this utility model, the disposable plastic pack is connected inside the baby bottle during use and then separated and discarded.

[0008] However, in this case, the process of attaching the plastic pack to the disposable baby bottle does not go smoothly. For example, when the user opens the bottle cap and inserts the plastic pack, they must insert the plastic pack downwards from the top of the bottle, but because the plastic pack is too long, it is often difficult to insert it correctly.

[0009] Meanwhile, Korean Patent No. 10-1624291 (May 19, 2016) discloses a foldable disposable baby bottle kit. According to this invention, the body of the baby bottle is accordion-shaped, so the baby bottle can be folded and its length can be reduced by about half. Furthermore, it is assumed that the used baby bottle will be discarded after feeding is finished.

[0010] Therefore, since this invention makes the entire baby bottle disposable, there is the burden of having to carry multiple baby bottles when going out for extended periods. [Overview of the project] [Problems that the invention aims to solve]

[0011] The purpose of this disclosure is to provide a disposable baby bottle that is convenient for carrying and using when going out, as the size of the bottle is adjustable.

[0012] Another object of this disclosure is to provide a disposable baby bottle that can be easily connected in plastic packs.

[0013] However, the purposes of this disclosure are not limited to those stated above. [Means for solving the problem]

[0014] The present disclosure provides a length-adjustable baby bottle comprising: a cap unit including a nipple and a cap and having a first fastening portion at the lower end of its inner surface; a first body section including a first region and a second region, the first region having a second fastening portion at the upper end of its outer surface which is connected to the first fastening portion and fastened to the cap unit, and the second region having a third fastening portion at the lower end of its outer surface; and a second body section having a fourth fastening portion at the upper end of its opening inner surface which is connected to the third fastening portion and fastened to the first body section, wherein when the third and fourth fastening portions are released, the first body section can be longitudinally housed in the second body section, thereby allowing the length of the baby bottle to be adjusted when stored. [Effects of the Invention]

[0015] The disposable baby bottle described in this disclosure has an adjustable body length, making it easy to carry and reducing the capacity of the outdoor bag used to carry the disposable baby bottle when going out. Furthermore, when attaching a plastic pack to the disposable baby bottle, the plastic pack is attached with the body of the bottle shortened. After that, by lengthening the body of the bottle, it becomes easier to attach a longer plastic pack to the disposable baby bottle. [Brief explanation of the drawing]

MODE FOR CARRYING OUT THE INVENTION

[0017] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings so that those skilled in the art can easily implement the present disclosure. However, the present disclosure is not limited to the embodiments described below and can be implemented in various modes. In the accompanying drawings, in order to clearly explain the present disclosure, components irrelevant to the explanation are omitted, and the same reference numerals are used for the same components throughout the specification.

[0018] Figure 1 is a front view of a disposable baby bottle according to one embodiment of the present disclosure. Referring to Figure 1, the disposable baby bottle 100 includes a cap unit 110, a first body section 120, and a second body section 130. The disposable baby bottle 100 is characterized by having a two-stage body structure.

[0019] The body of the disposable baby bottle 100 is formed by connecting a first body section 120 and a second body section 130 in the longitudinal direction. It is also possible to shorten the overall length of the body of the disposable baby bottle 100 by unconnecting the first body section 120 and the second body section 130. For example, the first body section 120 of the disposable baby bottle 100 can be housed longitudinally within the second body section 130.

[0020] The first body section 120 and the second body section 130 of the disposable baby bottle 100 may be made of transparent or opaque plastic. For example, the first body section 120 and the second body section 130 may be made of polycyclohexylene dimethylene terephthalate plastic (e.g., Tritan, Ecozen, or Estene).

[0021] The components of the disposable baby bottle 100 will be described below with reference to Figures 2 to 7. First, Figure 2 is a cross-sectional view of a cap unit 110 according to one embodiment of the present disclosure, and Figure 3 is a front view of the cap unit 110 according to one embodiment of the present disclosure.

[0022] Referring to Figure 2, the cap unit 110 includes a nipple 111, a cap 112, and a fastening portion 113. The nipple 111 is connected to the fastening portion 113 when in use and can be separated from the fastening portion 113 after use.

[0023] The cap 112 is connected to the fastening portion 113, thereby preventing the nipple 111 from being exposed to the outside. For example, the user can access the nipple 111 by opening the cap 112.

[0024] The fastening portion 113 includes a first fastening portion 114 on the inner surface of the opening. The fastening portion 113 is connected to the first fuselage section 120 via the first fastening portion 114. For example, the first fastening portion 114 may be a thread formed on the inner surface of the fastening portion 113. The fastening portion 113 can be screw-connected to the first fuselage section 120 via the first fastening portion 114.

[0025] Referring to Figure 3, the outer surface of the cap 112 is provided with measuring scales 115, and it can be used as a measuring cup. For example, a user can use the cap 112 as a measuring cup when filling a baby bottle with milk or breast milk for bottle-feeding an infant.

[0026] Figure 4 is a perspective view of a first fuselage section 120 according to one embodiment of the present disclosure. Referring to Figure 4, the first fuselage section 120 has a cylindrical shape including a first region 121 and a section region 122, wherein the diameter a' of the second region 122 is greater than the diameter a of the first region 121.

[0027] In this configuration, a portion of the first region 121 is connected to the cap 112, and a portion of the second region 122 is connected to the second fuselage section 130. Specifically, the first region 121 includes a second fastening portion 123 on its outer surface, and is connected to the cap unit 110 via this second fastening portion 123. For example, the second fastening portion 123 may be a thread formed around the first region. The first region 121 and the cap unit 110 can be connected by a screw connection between the second fastening portion 123 and the first fastening portion 114.

[0028] A step is provided at the upper end of the first region 121. That is, the upper end of the first region 121 is formed in a stepped shape and has a first surface 121a and a second surface 121b. The stepped structure at the upper end of the first region 121 prevents milk or breast milk inside the disposable baby bottle 110 from being exposed to the outside when bottle-feeding an infant.

[0029] Specifically, a plastic pack 10 is inserted into a disposable baby bottle 100, the opening of the plastic pack 10 is turned inside out, and the plastic pack 10 is connected to the upper end of the first region 121. Next, the first fastening portion 114 and the second fastening portion 123 are connected to the first region 121 and the fastening portion 113 of the disposable baby bottle 100. In this case, if the upper end of the first region 121 is thick, a gap will be created between the fastening portion 113 and the first region 121, and milk or breast milk may leak from that gap when feeding with a baby bottle.

[0030] Therefore, in this disclosure, a step is formed at the upper end of the first region 121 to minimize the area in contact with the vinyl pack 10 of the first surface 121a, and consequently minimize the gap between the upper end of the first region 121 and the fastening portion 113. This prevents milk or breast milk from leaking out of the baby bottle 100 when bottle-feeding.

[0031] On the other hand, a silicone liner may be used instead of a disposable plastic pack for the disposable baby bottle 100. In this case, the stepped structure at the upper end of the first region 121 can function as a support for the silicone liner. For example, when a silicone liner is attached to the disposable baby bottle 100, the opening of the silicone liner is held and fixed by the first surface 121a and the second surface 121b of the first region 121. That is, the first surface 121a and the second surface 121b of the first region 121 can function as a support for the silicone liner.

[0032] The second region 122 includes a third fastening portion 126 on the outer surface of its lower end, and is connected to the second fuselage section 130 via this third fastening portion 126. For example, the third fastening portion 126 may be formed on the front and back as threads formed around the outer surface of the lower end of the second region 122.

[0033] The second region 122 of the first fuselage section 120 includes a protruding edge 124 at its upper end. As shown in Figure 4, the protruding edge 124 protrudes over a predetermined area along the starting edge of the second region 122. At least one or more first projections 125 are formed on the protruding edge 124. For example, a total of four first projections may be formed on the protruding edge 124. The first projections 125 are for preventing unintended rotation of the first fuselage section 120 when it is housed in the second fuselage section 130. Specifically, when the first projections 125 of the first fuselage section 120 engage with the knurled portion 132 (see Figure 6) of the second fuselage section 130, rotation of the first fuselage section 120 within the second fuselage section 130 can be prevented.

[0034] For example, a user can open the cap unit 110 while the first fuselage section 120 is housed in the second fuselage section 130 by holding the cap unit 110 in one hand and rotating the second fuselage section 130 with the other hand, or by holding the second fuselage section 130 in one hand and rotating the cap unit 110 with the other hand. In this case, if the first fuselage section 120 is not fixed to the second fuselage section 130, the first fuselage section 120 may rotate.

[0035] Therefore, in the disposable baby bottle 100 according to this disclosure, the first projection 125 and the knurled portion 132 of the second body section 130 engage with each other, thereby fixing the first body section 120 inside the second body section 130. Consequently, the second body section 130 can prevent the first body section 120 from rotating inside the second body section 130.

[0036] Furthermore, the first projection 125 can prevent overrunning. Specifically, when the second fuselage section 130 is detached from the first fuselage section 120 and moved upward with the first fuselage section 120 housed inside, the movement of the second fuselage section 130 is stopped by the first projection 125. Therefore, it is possible to prevent the second fuselage section 130 from moving beyond the first fuselage section 120.

[0037] As shown in Figure 4, the second projection 127 and the third projection 128 may be formed parallel to each other at a predetermined interval on the third fastening portion 126 of the first fuselage section 120. Alternatively, a fourth projection 129 may be formed at a position on the extension of the third fastening portion 126, spaced apart from the third fastening portion 126.

[0038] Furthermore, although not shown in Figure 4, in the first fuselage section 120, a third fastening portion 126' may be formed on the opposite side of the illustrated third fastening portion 126, and a second projection 127' and a third projection 128' may be formed parallel to it with a predetermined gap between them. A detailed explanation of this is omitted in lieu of the explanation of the third fastening portion 126.

[0039] Furthermore, a fourth projection 129' may be formed on the same line as the third fastening portion 126', but spaced apart from the third fastening portion 126'. A detailed explanation of this will be omitted in lieu of the explanation of the third fastening portion 126.

[0040] A groove is formed between the second projection 127 and the third projection 128, which are formed at a predetermined interval, and this groove can increase the connecting force between the first fuselage section 120 and the second fuselage section 130.

[0041] For example, in the process of screw-connecting the first fuselage section 120 and the second fuselage section 130 via the third fastening portion 126 and the fourth fastening portion 131, the groove formed between the second projection 127 and the third projection 128 is engaged with the locking step 134 (see Figure 6) formed on the fourth fastening portion 131. As a result, the first fuselage section 120 and the second fuselage section 130 are connected by screws between the third fastening portion 126 and the fourth fastening portion 131, and the connection force can be increased by the additional fastening between the groove formed by the second projection 127 and the third projection 128 and the locking step 134.

[0042] Furthermore, the height of the second projection 127 is greater than the height of the third projection 128 and the same as the height of the fourth projection 129. The second projection 127 and the fourth projection 129 are projections for connecting to the base 140 (see Figure 7), which will be described later. For example, when the first fuselage section 120 is housed in the second fuselage section 130, the first fuselage section 120 is connected to the base 140.

[0043] Specifically, the first fuselage section 120 is connected to and fixed to the base 140 by the engagement of the second projection 127 and the fourth projection 129, which are formed on the surface of the lower portion of the first fuselage section 120, with the inner edge 143 of the base 140.

[0044] Furthermore, the second projection 127, which is higher than the third projection 128, prevents the second fuselage section 130 from overrunning. For example, when the first fuselage section 120 and the second fuselage section 130 are screw-connected via the third fastening portion 126 and the fourth fastening portion 131, the second projection 127 can prevent the third fastening portion of the first fuselage section 120 from further rotating along the fourth fastening portion 131 of the second fuselage section 130. A more detailed explanation is provided below with reference to Figure 6.

[0045] On the other hand, the first body section 120 can be separated from the second body section 130. For example, by removing the screw connection between the third fastening part 126 and the fourth fastening part 131, the first body section 120 and the second body section 130 can be separated. Specifically, when the screw connection between the first body section 120 and the second body section 130 is held in place by the second projection 127, applying further force in the direction of movement of the second body section 130 and rotating it further will cause the fourth fastening part 131 to separate from the second projection 127, and the first body section 120 will separate. This allows the user to manage the disposable baby bottle 100 more easily when washing and storing it.

[0046] Figure 5 is a front view of a second fuselage section according to one embodiment of the present disclosure, and Figure 6 is a perspective view of a second fuselage section according to one embodiment of the present disclosure. Referring to Figure 5, the second fuselage section 130 has a cylindrical shape with a larger diameter than the diameter of the first fuselage section 120, where the diameter (b) of the second fuselage section 130 is larger than the diameter (a') (second region) of the first fuselage section 120.

[0047] Furthermore, as shown in Figure 5, the diameter of the second fuselage section 130 increases downwards, so the diameter b' of the lower portion is larger than the diameter b of the upper portion. In other words, the upper and lower cross-sections of the second fuselage section 130 may be trapezoidal in shape.

[0048] In general, the lower part of the plastic pack 10 inserted into the disposable baby bottle 100 expands due to its structure when milk or breast milk is filled into the plastic pack 10. However, when the lower part of the plastic pack 10 expands, the measuring scale on the surface of the plastic pack becomes inaccurate.

[0049] However, in the disposable baby bottle 100 according to this disclosure, the lower portion of the second body section 130 is formed to be wider than the upper portion, thus solving the problem of the lower portion of the plastic pack 10 being wider.

[0050] Referring to Figure 6, the second fuselage section 130 includes a fourth fastening portion 131 on the inner surface of its upper portion. For example, the fourth fastening portion 131 may be a thread formed around the inner surface of the upper portion of the second fuselage section 130. As shown in Figure 6, the fourth fastening portion 131 may be divided into four regions on the inner surface of the upper portion of the second fuselage section 130.

[0051] The second fuselage section 130 is connected to the first fuselage section 120 via a fourth fastening portion 131. For example, the fourth fastening portion 131 of the second fuselage section 130 and the third fastening portion 126 of the first fuselage section 120 can be screw-connected.

[0052] For example, the fourth fastening portion 131 may have four threads. Increasing the area of ​​the fourth fastening portion 131 can improve the connection force between the second fuselage section 130 and the first fuselage section 120.

[0053] The fourth fastening portion 131 includes a plurality of threaded projections 133 and a knurled portion 132. First, the plurality of threaded projections 133 are for protecting the surface of the first body section 120 and may be formed, for example, at both ends of the threads of the fourth fastening portion 131.

[0054] Specifically, the multiple threaded projections 133 prevent the fourth fastening portion 131 from damaging the surface of the first fuselage section 120 during the process of moving the second fuselage section 130 upward to accommodate the first fuselage section 120.

[0055] On the other hand, the knurled portion 132 is for preventing the first fuselage section 120, which is housed in the second fuselage section 130, from rotating, and may be, for example, a plurality of protrusions projecting along the inner edge of the upper portion of the second fuselage section, as shown in Figure 6.

[0056] Specifically, when the first fuselage section 120 is housed in the second fuselage section 130, the knurled portion 132 engages with the first projection 125 of the first fuselage section 120, thereby fixing the first fuselage section 120 to the second fuselage section 130. Therefore, it is possible to prevent the first fuselage section 120 from rotating within the second fuselage section 130.

[0057] Furthermore, the second fuselage section 130 includes a locking step 134 in the fourth fastening portion 131. The locking step 134 is intended to improve the coupling force between the first fuselage section 120 and the second fuselage section 130 and may be formed, for example, between the threads of the fourth fastening portion 131.

[0058] Specifically, in the process of screw-connecting the second fuselage section 130 to the first fuselage section 120, the locking step 134 engages with the groove between the second projection 127 and the third projection 128 of the first fuselage section 120.

[0059] Referring again to Figure 5, the second fuselage section 130 has a grip 135 on the outer surface of its upper portion. The grip 135 is intended to improve the user's grip, and may, for example, have sawtooth-like grooves on a predetermined area of ​​the outer surface of the second fuselage section 130.

[0060] The grip 135 may be formed on the outer surface corresponding to the fourth fastening portion 131 formed on the inner surface. For example, if the user grips the grip 135 when connecting the second fuselage section 130 to the first fuselage section 120, it is possible to prevent slippage when rotating the second fuselage section 130.

[0061] Figure 7 is a perspective view of a base 140 according to one embodiment of the present disclosure, the disposable baby bottle 100 may further include the base 140. The base 140 is connected to the second body section 130 to form the bottom of the disposable baby bottle 100. Referring to Figure 7, the base 140 is composed of a first step 141 and a second step 142 so as to have a step.

[0062] The first stage 141 includes an inner edge 143 and an outer projection 145. Specifically, the inner edge 143 is formed along the inner surface of the first stage 141 and connects to the first fuselage section 120. For example, when the first fuselage section 120 is housed in the second fuselage section 130, the lower end of the first fuselage section 120 is connected to the base 140. Specifically, the base 140 serves to secure the first fuselage section 120 to the second fuselage section by pressing the outer side of the lower end of the first fuselage section 120 with the inner edge 143.

[0063] Multiple outer protrusions 145 are formed on the outer surface of the first stage 141. For example, the base 140 may include a total of four outer protrusions 145, and the outer protrusions may be formed on the outer surface of the first stage 141 at predetermined intervals. Specifically, the base 140 fixes the second fuselage section 130 and forms a bottom, providing airtightness, by pressing the inner side of the lower end of the second fuselage section 130 with the outer protrusions 145.

[0064] The base 140 further includes a handle 144. For example, the base 140 may include a handle 144 having a predetermined area in a predetermined region outside the second stage 142. This allows the user to use the handle 144 when attaching the base 140 to the second fuselage section 130 or the first fuselage section 120, or when removing the base 140 from them.

[0065] Figure 8 is a cross-sectional perspective view of the disposable baby bottle shown in Figure 1, viewed from direction A-A'. As shown in Figure 8, the cap unit 110 is connected to the first body section 120, and the first body section 120 is connected to the second body section 130. Furthermore, the second body section 130 is connected to the base 140.

[0066] As described above, the cap unit 110 is connected to the first fuselage section 120 by fastening the first fastening portion 114 and the second fastening portion 123, and the first fuselage section 120 is connected to the second fuselage section 130 by fastening the third fastening portion 126 and the fourth fastening portion 131.

[0067] In this configuration, the fastening means between the first fastening portion 114 and the second fastening portion 123, and the fastening means between the third fastening portion 126 and the fourth fastening portion 131, include common fastening means such as screw threads, locking steps, L-shaped locking steps, protrusions, grooves, etc., and the connections between the fastening means include screw thread connections, screw connections, rotary connections, and fittings. Among these connection types, the screw connection illustrated in Figure 8 is the most preferred.

[0068] Figure 9 shows a disposable baby bottle in which the first body section is housed in the second body section, and Figure 10 is a cross-sectional perspective view of the first body section of Figure 9 as seen from the D-D' direction. Referring to Figure 9, with the disposable baby bottle 100, the first body section 120 can be housed in the second body section 130 by unconnecting the first body section 120 and the second body section 130 and moving the second body section 130 upward. This makes it possible to shorten the overall length of the disposable baby bottle 100.

[0069] Referring to Figure 10, the second fuselage section 130 can be connected to the first fuselage section 120 while housing it inside.

[0070] The first projection 125 at the upper end of the first fuselage section 120 prevents unintended rotation of the first fuselage section 120 when it is housed in the second fuselage section. For example, when the first fuselage 120 and the second fuselage 130 are overlapping, and a user holds the second fuselage 130 with one hand and rotates the cap 110 with the other hand to open the cap 110, the first projection 125 engages with the knurled portion 132 of the second fuselage 130, preventing the first fuselage 120 from rotating away from the second fuselage 130.

[0071] Furthermore, the first projection 125 formed at the upper end of the first fuselage section 120 prevents the second fuselage section 130 from moving upward beyond the first fuselage section 120.

[0072] The first fuselage section 120, housed within the second fuselage section 130, is connected to the base 140. Specifically, the base 140 is connected to the lower portion of the first fuselage section 120 by the inner edge 143 engaging with the second projection 127 and the fourth projection 129 of the first fuselage section 120.

[0073] Other embodiments of the present disclosure will be described below with reference to Figure 11. The disposable baby bottles of the present disclosure described herein can be folded into a three-tiered, four-tiered, or the like, so that the length for storage can be shortened.

[0074] In the following explanation, we will omit the explanation of components that are the same as those described above, such as the cap unit 110, and will only explain the different components.

[0075] Figure 11 is a front view of a disposable baby bottle according to another embodiment of the present disclosure. Referring to Figure 11, the disposable baby bottle 200 according to another embodiment may further include one or more body sections connected to the second body section 230. That is, the body sections of the disposable baby bottle may be configured in two or more stages.

[0076] The second fuselage section 230 has a straight cylindrical shape with a cylindrical cross-section and a fifth fastening portion at the lower end of its outer surface. The third fuselage section 240 has a trapezoidal cross-section, with a cylindrical shape where the lower part is wider than the upper part, and a sixth fastening portion at the upper end of the inner surface of the opening.

[0077] Therefore, the second body section 230 is connected to the third body section 240 by fastening the fifth and sixth fastening portions together. For example, the fifth and sixth fastening portions may have screw threads so that they can be screw-connected. The base 140, when connected to the third body section 240, forms the bottom of the disposable baby bottle 200.

[0078] In this case, the fastening means between the fifth and sixth fastening portions include common fastening means such as screw threads, locking steps, L-shaped locking steps, protrusions, grooves, etc., and the connection between the fastening means includes screw thread connections, screw connections, rotary connections, and fitting. Among these connection types, screw connections are the most preferred.

[0079] On the other hand, as described above, by moving the second fuselage section 230 in the longitudinal direction, the first fuselage section 120 can be accommodated within the second fuselage section 230, and by moving the third fuselage section 240 in the longitudinal direction, both the first fuselage section 120 and the second fuselage section 230 can be accommodated within the third fuselage section 240.

[0080] Specifically, by separating the fifth and sixth fastening portions and moving the third fuselage section 240 longitudinally, the first fuselage section 120 and the second fuselage section 230 can be accommodated within the third fuselage section 240.

[0081] As a result, the first torso section 120, the second torso section 230, and the third torso section 240 overlap each other, making it possible to shorten the overall length of the torso of the disposable baby bottle 200.

[0082] As described above, the disposable baby bottle relating to this disclosure may further include, for example, a fourth body section (not shown), a fifth body section (not shown), a sixth body section (not shown), etc., connected to the third body section 240.

[0083] Figure 12 is a diagram comparing the lengths of two-tiered and three-tiered disposable baby bottles. Figure 12A is a disposable baby bottle 200 with a three-tiered body section, and Figure 12B is a disposable baby bottle 100 with a two-tiered body section.

[0084] Referring to Figures 12A and 12B, it can be seen that, in the folded state, the length C of the body of the disposable baby bottle 200 with a three-section body is shorter than the length C' of the body of the disposable baby bottle 100 with a two-section body.

[0085] The body sections of the disposable baby bottles 100 and 200 according to this disclosure are configured in a two-tiered and three-tiered manner, but may be designed in a four-tiered or more manner as needed.

[0086] Figure 13 shows a disposable baby bottle 100 with a plastic pack attached. Referring to Figure 13, the user opens the cap unit 110 and base 140 of the disposable baby bottle 100, places the plastic pack 10 inside, and closes the cap unit 110 to secure the plastic pack 10 for use. Alternatively, the user may open the cap 110 and base 140 of the disposable baby bottle 100, overlap the first body part 120 and the second body part 130 to shorten the length of the body, and then insert the plastic pack 10.

[0087] Subsequently, the user turns the opening of the plastic pack 10 inside out, places this opening over the opening of the disposable baby bottle 10, and then connects the fastening portion 113 to secure the plastic pack 10 to the baby bottle. Specifically, the second fastening portion 123 of the first body section 120 and the first fastening portion 114 of the cap unit 110 are screw-connected.

[0088] The disposable baby bottle 100 of this disclosure allows the user to insert and secure the plastic pack 10 while adjusting the length of the body, making it easier for the user to attach the plastic pack 10.

[0089] As described above, after attaching the plastic pack 10 to the disposable baby bottle 100, the user can put milk or breast milk for bottle-feeding the infant into the plastic pack 10 and then bottle-feed the infant. The opening of the disposable baby bottle 100 of this disclosure, i.e., the upper end of the first region 121, is designed to have steps 121a and 121b, so that the contents at the bottom can be prevented from leaking out between the plastic pack 10 and the fastening portion 113.

[0090] After the substance has been consumed, the user removes the plastic pack 10 attached to the disposable baby bottle 100, unconnects the first body section 120 and the second body section 130, and then inserts the first body section 120 into the second body section 130 and connects them, thereby shortening the length of the disposable baby bottle 100 and making it easier to carry the baby bottle.

[0091] On the other hand, since the first body section 120 and the second body section 130 of the disposable baby bottle 100 are separate, the baby bottle is easy to clean.

[0092] The above description is provided as an exemplary embodiment of the Disclosure, and those skilled in the art should understand that the Disclosure can be easily modified in various ways without altering the spirit or essential features of the Disclosure. Accordingly, the above-described embodiments are merely illustrative and should not be construed as limiting in any respect.

[0093] Furthermore, the scope of this disclosure is defined by the claims rather than the detailed description above, and all changes and modifications arising from the intent and scope of the claims and the concept of equivalents should be construed as being included within the scope of this disclosure.
