Abstract

The utility model discloses an infusion bottle bottom structure, bottle end are oval, including bottle end main part, bottle end main part comprises the oval pit of locating bottom surface side wall all around and locating bottom surface central authorities, the cross-section of oval pit is the arc, the side wall on be equipped with trapezoidal breach. The utility model discloses enclose out the trapezoidal breach that sets up a plurality of partitions to the side at infusion bottle bottom, make the tensile space increase of bottom, change at the blowing in-process product and take shape easily plump, stabilized the structure of product, make the product easily stand steadily, improved the qualification rate of product. In addition, the cross section of the oval concave pit is set to be arc-shaped, so that the phenomena of bottom material accumulation and bottom outward protrusion are effectively avoided, and the production cost is saved.

Description

Structure of bottom of infusion bottle

Technical Field

The utility model relates to an infusion bottle especially relates to a structure at bottom of infusion bottle.

Background

The infusion bottle is used for containing liquid which is infused into human bodies and is prepared for medical use when a patient is infused. At present, the infusion bottle is developed from an original glass bottle to a plastic bottle, and the plastic infusion bottle can be produced in a large batch by a blow molding mode.

Although a plastic infusion bottle in the prior art is widely applied to the medical market, some defects exist in the actual production process, as shown in fig. 1 and 2, in the blow molding process of the traditional infusion bottle, because the side wall 3 at the bottom of the traditional infusion bottle is of a closed-loop oval structure, the stretching space is too small, the traditional infusion bottle is not fully blown during blow molding, and the plastic infusion bottle is not easy to form and affects the standing of a product; in addition, the bottom surface of the elliptic pit 2 at the bottom of the infusion bottle is of a plane structure, so that the bottom material of the bottle blank is not easy to stretch during blow molding, the phenomena of bottom material accumulation and bottom outward protrusion are caused, the qualification rate of products is reduced, and the waste on cost is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide an infusion bottle bottom structure which is easier to form and is easy to fill, high in product qualification rate and stable in product standing in the blow molding process.

The purpose of the utility model is realized through the following technical scheme:

the bottle bottom structure of the infusion bottle is oval, and comprises a bottle bottom main body, wherein the bottle bottom main body is composed of side walls arranged on the periphery of a bottom surface and an oval pit arranged in the center of the bottom surface, the cross section of the oval pit is arc-shaped, and a trapezoidal notch is formed in the side wall.

Preferably, the trapezoidal notch is a plurality of.

Preferably, the trapezoidal notches are equally distributed in the center of the bottle bottom main body.

Preferably, the number of the trapezoid notches is two.

Preferably, the bottom surface of the trapezoidal notch is flush with the end surface of the oval concave pit.

The utility model has the advantages that:

1) the utility model discloses set up the trapezoidal breach of a plurality of partitions in infusion bottle bottom side wall department, make the tensile space increase of bottom, change at the blowing in-process product and take shape easily plump, improved the qualification rate of product.

2) The utility model discloses the cross-section of well oval pit is the arc, the effectual phenomenon of having solved the long-pending material in bottom and bottom evagination.

3) The trapezoidal notch is opened to bottle bottom side wall, has more stabilized the structure of product, makes the product easily stand steadily to reduce the rejection rate, still practiced thrift manufacturing cost.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 3-4, the present invention provides a technical solution:

the bottle bottom structure of the infusion bottle is oval, and comprises a bottle bottom main body 1, wherein the bottle bottom main body 1 is composed of side walls 3 arranged on the periphery of a bottom surface and an oval pit 2 arranged in the center of the bottom surface, the cross section of the oval pit 2 is arc-shaped, a trapezoidal notch 4 is arranged on the side walls 3, and the bottom surface of the trapezoidal notch 4 is flush with the end surface of the oval pit 2.

The number of the trapezoidal notches 4 can be multiple, and the trapezoidal notches 4 are distributed in the center of the bottle bottom main body 1 in an equal dividing way.

In this embodiment, two trapezoidal notches 4 are symmetrically arranged as shown in fig. 4.

The utility model discloses enclose out the trapezoidal breach that sets up a plurality of partitions to the side at infusion bottle bottom, make the tensile space increase of bottom, change at the blowing in-process product and take shape easily plump, improved the qualification rate of product. In addition, the cross section of the oval concave pit is set to be arc-shaped, so that the phenomena of material accumulation at the bottom and outward protrusion of the bottom are effectively solved.

The side wall of the bottom of the bottle body is provided with the trapezoidal notch, so that the structure of the product is stabilized, the product is easy to stand stably, the rejection rate is reduced, and the production cost is saved.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
