Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a baby bottle.

[Prior Art] As a conventional baby bottle, for example, there is one shown in FIG.

In the figure, 1 is a bottle body, 2 is a nipple, and 3 is a mounting cap. The bottle body 1 is in the form of a thin cylinder as a whole, and a small bottle mouth 4 is provided at the upper end thereof.

As for the size of a general baby bottle, the inner diameter d ₀ of the bottle mouth 4 is 30 mm.
However, the maximum inner diameter D ₀ of the body is about 45 mm.

[Problems to be Solved by the Invention] However, in such a conventional baby bottle, the bottle mouth 4
Since the inner diameter d ₀ of the bottle was formed to be small, it was not possible to put the fingers all the way into the bottle when washing. Therefore, since I was washing the inside with a brush,
There is a problem that the degree of dirt removal cannot be known by touching with a finger, a satisfactory feeling of cleaning cannot be obtained, and uncleanliness tends to occur.

Further, when the powdered milk is put into the feeding bottle by using a large-sized spoon, the tip of the spoon does not enter the bottle mouth 4, so that the powdered milk is easily spilled outside.

The present invention has been made in view of such conventional problems, and an object thereof is to solve the above problems by setting a large inner diameter of a bottle mouth.

[Means for Solving the Problems] In order to achieve the above object, the baby bottle of the present invention comprises:
The inner diameter of the bottle mouth where the nipple is attached via the mounting cap is 4
It is characterized in that it is 0 mm or more and the inner diameter of the bottle mouth is 80% or more of the maximum inner diameter of the body portion.

[Operation] Since the inner diameter of the bottle mouth is formed large, the inside of the bottle can be easily cleaned and hygienic feeding can be performed.
It is possible to easily carry out operations such as transferring breast milk or adding powdered milk, and prevent spilling of breast milk or powdered milk.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

1 and 2 are views showing an embodiment of the present invention.

First, the structure will be described. In FIG. 1, reference numeral 5 denotes a bottle body, which is made of a synthetic resin material such as polypropylene. The body 6 of the bottle body 5 has a gourd-shaped body with a slightly thin central portion, and its diameter is set large for its height.

The bottle mouth 7 of the bottle body 5 is formed to have a slightly smaller diameter than the body portion 6, and a screw portion 8 is provided on the outer peripheral surface. Inner diameter d of bottle mouth 7
Is 40 mm or more and 80% of the maximum inner diameter D of the body portion 6
It is set as described above. For example, there is a case where the inner diameter d of the bottle mouth 7 is 45 mm and the maximum inner diameter D of the body portion 6 is 53 mm.

Reference numeral 9 is a nipple that covers the front surface of the bottle mouth 7, and 10 is a mounting cap for mounting the nipple 9 on the bottle mouth 7. The mounting cap 10 has a threaded portion 11 that fits into the threaded portion 8 on the inner end surface, and a through hole 12 through which the body portion of the nipple 9 penetrates is provided in the center.

Next, the operation will be described.

This baby bottle is used in the same manner as the conventional one.

That is, for example, powdered milk and hot water are put in the bottle body 5, and the mounting cap 10 having the nipple 9 mounted thereon is screwed into the bottle mouth 7 and tightened. Then, the baby bottle is shaken to stir the powdered milk and the hot water inside, and when both are sufficiently mixed, they are appropriately cooled and the baby is fed.

In this case, assuming that the inner diameter d of the bottle mouth 7 according to the present embodiment is 45 mm and the inner diameter d ₀ of the conventional bottle mouth 4 is 30 mm, the respective bottle mouths 7, 4 are
Area A, _{A 0} of becomes ^{A = πd 2/4 = π} × 45 2/4 = 1589.6mm 2 A 0 = πd 0 2/4 = π × 30 2/4 = 706.5mm 2. Therefore, the ratio of the areas of both bottle mouths 7 and 4 is A: A ₀ = 1589.6: 706.5 = 2.25: 1. In this way, if the diameter of the bottle mouth is 1.5 times,
The area is 2.25 times, and the opening area can be greatly increased by slightly increasing the inner diameter of the bottle mouth 7.

As a result, by increasing the opening area of the bottle mouth 7,
Since a large spoon for the scooping portion can be used, and the large scooping portion can be put into the bottle mouth 7 to put powdered milk or the like into the bottle body 5, it is easy to put powdered milk or the like, and There is no fear of spilling milk powder or the like outside the bottle. Furthermore, since the bottle mouth 7 is wide, it is possible to insert the finger all the way into the back and wash it cleanly, which is easy and hygienic. Moreover, as is clear from FIGS. 1 and 4, by increasing the inner diameter of the bottle mouth 7 and increasing the through hole 12 of the mounting cap 10, the shape of the nipple 9 can be made closer to that of the mother. Therefore, it is easy to drink and it is possible to promote lactation.

FIG. 3 shows another embodiment of the present invention, which is a bottle body 5
The body 6 is formed in a hexagonal shape.

In this case, the maximum inner diameter D of the body portion 6 is a diagonal length that maximizes the inner diameter. The other structure is the same as that of the above-mentioned embodiment, and the same operation and effect as those of the above-mentioned embodiment can be obtained by this structure as well.

[Effects of the Invention] As described above, the present invention is configured as described above, and thus has the following effects.

By increasing the opening area of the bottle mouth, you can use spoons of various sizes and insert a large scooping part into the bottle mouth to put powdered milk etc. It is possible to provide a baby bottle that is easy to put, and that can easily replace breast milk and the like, and that does not spill breast milk, powdered milk, or the like outside the bottle.

Moreover, since the bottle mouth is wide, the inside of the bottle body can be inserted with a finger to wash the inside cleanly, and a hygienic baby bottle that is easy to wash and hygienic can be obtained. Furthermore, since the diameter of the through hole of the mounting cap can be increased by increasing the inner diameter of the bottle mouth,
A nipple having a shape similar to that of a mother's nipple can be attached, and thus, it is easy to drink and promotes feeding.
