Embodiment Construction
[0010] The present invention is further illustrated below by specific examples.
[0011] Such as figure 1 , figure 2 Shown, a kind of plastic bottle and bottle cap combination that is convenient to extrude, it comprises plastic bottle 1, bottle cap 2 and soft bag 3, and soft bag 3 is located in plastic bottle 1, and bottle cap 2 covers on plastic bottle 1; The side of the mouth of the plastic bottle has a through hole; the side of the soft bag 3 is bonded to the inner wall of the plastic bottle 1 at the parting line, and the bottom of the soft bag 3 is bonded to the bottom of the inner wall of the plastic bottle 1 at the parting line. 3. The top opening is bonded to the inner wall of the mouth of the plastic bottle 1; thus, the space between the plastic bottle 1 and the soft bag 3 communicates with the outside world through the through hole 4 on the side of the mouth of the plastic bottle 1; There is a through hole, after the bottle cap and the bottleneck of the plastic bot...

The invention relates to the field of living goods, in particular to an extrusion-convenient plastic bottle structure. The extrusion-convenient plastic bottle and bottle cap combination comprises a plastic bottle and a soft bag arranged in the plastic bottle, and is characterized in that the side surface of the soft bag and the inner wall of the plastic bottle are bonded on a mold closing line; the bottom of the soft bag and the bottom of the inner wall of the plastic bottle are bonded on the mold closing line; the opening edge at the top of the soft bag and the top edge of the bottle opening of the plastic bottle are bonded; and two through holes are formed in the side surface of the bottle opening of the plastic bottle. The plastic bottle adopts the structural design, and only consists of two parts as the plastic bottle and the soft bag; as the soft bag is provided with bonding points at the periphery with the plastic bottle, the soft bag is firmly fixed in the plastic bottle; and when the bottle body is extruded, the outer-layer plastic bottle can recover the initial shape through two through holes after the extruding force is disappeared, but the shape of the inner-layer soft bag cannot be recovered, and the soft bag cannot be deformed and displaced, so that the extrusion of contents inside at the next time is facilitated.
Description
technical field [0001] The invention relates to the field of daily necessities, in particular to a combination of a plastic bottle and a bottle cap that is easy to squeeze. Background technique [0002] The invention patent application document with the publication number CN1055714A discloses a plastic bottle structure, which aims to overcome the defect that the traditional plastic bottle structure is not conducive to quickly and conveniently extruding the liquid or paste content from the bottle. However, the structure of the plastic bottle body and bottle cap disclosed in this patent application is too complicated, resulting in high production costs and inconvenient use. At the same time, it still cannot completely overcome the difficulty of squeezing liquid or pasty contents from the bottle. out of the question. Contents of the invention [0003] The object of the present invention is to provide a simple and easy-to-use plastic bottle structure, which can effectively ov...
