JPH08187272A - Feeding bottle with detachable bottom lid - Google Patents

Abstract

PURPOSE: To provide a feeding bottle with a detachable bottom lid capable of removing the bottom lid from the feeding bottle shell and cleaning the feeding bottle shell extremely easily, by making the bottom part of the feeding bottle shell openable and the bottom lid freely detachably cover the bottom. CONSTITUTION: The bottom of this feeding bottle shell 3 made of a plastic or glass, transparent or semi-transparent is openable, and the bottle shell 3 is put with a scale 32 to show the liquid quantity on the outer periphery face. The tip of a bottom lid 2 is bent inward and its periphery face is elastically pressed to a contact part 21 of the bottle shell 3, and the bottom end part of the feeding bottle shell is pressed to a contact part 22. Since the bottom lid 2 is doubly and strongly engaged with the feeding shell 3 by the two contact parts 21 and 22, milk or a drink to be fed is prevented from leaking out from the engaging part, and the bottom lid can be easily and detachably attached. The cross section of the bottom lid 2 is formed in a one-side-open rectangle to form a protrusion 33 protruded outward from the outer periphery face of the bottom end of the feeding bottle shell 3. Thus, the elastic bottom lid 2 can be easily detached from and securely be in contact with the elastic protrusion 33.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baby bottle having an opening at the bottom of a baby bottle and a detachable bottom lid for facilitating the cleaning of the baby bottle.

[0002]

Generally, a baby bottle has an elongated cylindrical shape, and it is not easy to clean the inner peripheral surface, especially the bottom. Therefore, a device for facilitating cleaning is required.

[0003]

SUMMARY OF THE INVENTION The present invention has an opening at the bottom of a conventional feeding cylinder, and a bottom cover is removably attached to the opening to facilitate cleaning.

That is, the baby bottle of the present invention comprises a nipple holder for holding a nipple member, a baby tube which engages with the nipple holder, and a detachable bottom lid which engages with an open bottom end of the baby tube. Is characterized in that In particular, the bottom lid is made of an elastic plastic, and a convex portion is provided on the outer peripheral surface of the bottom end portion of the feeding cylinder and / or the inner peripheral surface of the bottom lid to ensure the sealing performance when the bottom lid is engaged with the feeding cylinder. I'm perfect. The bottom of the baby bottle is open, made of plastic or glass,
Further, it is transparent or translucent, and a scale indicating the liquid amount is attached to the outer peripheral surface.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a baby bottle of the present invention. The bottom lid 2 is a round lid made of elastic plastic. The bottom lid 2 is completely engaged with the bottom end portion of the feeding cylinder 3 described below, and the beverage in the feeding cylinder 3 does not leak from the engaging portion.

[0006] The feeding tube 3 is a cylindrical glass, has an opening at the bottom, allows the bottom lid to be detachably engaged, and is mounted so that the airtightness is perfect when the bottom lid is engaged. A male screw 31 is formed on the outer peripheral edge of the upper portion of the feeding tube 3. The male screw 31 and the female screw 51 of the nipple holder 5 described later mesh with each other to securely engage the nipple member 4.

The nipple member 4 is a conventionally known one made of silicone rubber or the like.

The nipple holder 5 includes, for example, a nipple member 4
A concave fitting portion 52 for fitting the outer peripheral edge 41 is formed on the inner peripheral edge. Further, a female screw 51 that meshes with the male screw 31 of the feeding cylinder 3 is formed on the inner peripheral edge. The concave fitting portion 52 is
The outer peripheral edge of the nipple member 4 is surely held and fitted, but the outer peripheral edge of the nipple member 4 is formed to be slightly larger and formed so as to be joined to the concave fitting portion 52 of the nipple holder 5 without a gap. Good. The female screw 51 on the inner side of the nipple holder 5 meshes with the male screw 31 on the outer side of the feeding cylinder 3 and securely engages them. Further, the female screw 51 of the nipple holder 5 and the feeding tube 3
The outer peripheral edge 4 of the nipple member 4 by the tightening force with the male screw 31 of
The lower part of 1 and the upper part of the male screw 31 of the feeding tube 3 are joined and hermetically sealed so that the milk for childcare 6 or the beverage does not leak from the engaging part. A screw or a recess may be further formed on the upper outer peripheral edge of the nipple holder 5 so that the nipple holder 5 can be joined to the cap that protects the nipple member 4.

FIG. 2 is a sectional view of the first embodiment showing the engaging portion between the bottom cover 2 and the feeding cylinder 3. The bottom lid 2 is made of elastic plastic. The tip of the bottom lid 2 is bent inward, the outer peripheral surface of the feeding tube 3 and the contact portion 21 are elastically pressed against each other, and the bottom end of the feeding tube 3 and the contact portion 22 are further in contact.
And are in pressure contact. In this way, the double contact portions 21, 22
Due to the strong engagement between the bottom lid 2 and the feeding cylinder 3,
The baby emulsion 6 or the beverage does not leak from the engaging portion, and the bottom lid 2 can be easily attached to and detached from the feeding cylinder 3.

FIG. 3 is a sectional view of the second embodiment showing the engaging portion between the bottom lid 2 and the feeding tube 3. The bottom lid 2 is made of elastic plastic. The cross section of the bottom cover 2 is bent in a U shape. A convex portion 33 protruding outward is formed on the outer peripheral surface of the bottom end portion of the feeding tube 3. Since the convex portion is formed on the outer peripheral surface of the bottom end portion of the feeding cylinder 3, the feeding cylinder 3 is easily attached to and detached from the elastic bottom lid 2, and firmly adheres thereto.

FIG. 4 shows a modification of the convex portion 33 of the feeding tube 3 shown in FIG. In the outer peripheral surface of the bottom end portion of the feeding tube 3, convex portions 33 and 33 'are provided in two stages. In this case, the convex portion 23 that comes into pressure contact with the inner peripheral surface of the bottom lid 2 between the convex portions 33 and 33 ′ of the nursing cylinder 3
Is preferably provided. In this way, the convex portion 2 of the bottom lid 2
3 and the convex portions 33 and 33 ′ of the feeding cylinder 3 are in pressure contact with and engaged with each other, the milk for childcare 6 or the beverage does not leak from the engaging portion, and the bottom lid 2 can be easily attached to the feeding cylinder 3. Can be attached and detached.

FIG. 5 is a sectional view of the third embodiment showing the engagement state between the bottom lid 2 and the feeding cylinder 3. The bottom lid 2 is molded of plastic, and a female screw 24 is formed on the inner peripheral surface of the tip portion of the bottom lid 2. A male screw 34 is formed outside on the outer peripheral surface of the lower end portion of the feeding tube 3. By engaging the bottom lid 2 with the feeding cylinder 3, it is possible to easily attach / detach and ensure close contact.

[0013]

Since the conventional bottle body is divided into the bottom lid and the feeding cylinder, and the bottom lid can be detached from the feeding cylinder, it becomes extremely easy to wash the feeding bottle.
