Disposable vacuum fresh-keeping soft barrel and vacuum fresh-keeping water taking device

Abstract

The invention provides a disposable vacuum fresh-keeping soft barrel. The disposable vacuum fresh-keeping soft barrel comprises a barrel body and a barrel bottom. The barrel body comprises a plurality of barrel body side walls. The barrel body side walls are connected end to form a polygon prism structure. Each barrel body side wall is provided with wavy wrinkles distributed in the axial direction of the barrel body, so that the barrel body side walls can be compressed in the axial direction. The barrel bottom is arranged at one end of the barrel body and is in sealed connection with the barrel body, so that a containing cavity used for storing water is formed. The barrel bottom comprises a plurality of first reinforcing grooves. The first reinforcing grooves are formed around the middle area of the barrel bottom and extend outwards from the middle area of the barrel bottom. The number of the first reinforcing grooves corresponds to the number of the barrel body side walls, and each first reinforcing groove is perpendicular to the corresponding barrel body side wall. The first reinforcing grooves are formed and are perpendicular to the barrel body side walls, and when the barrel body of the disposable vacuum fresh-keeping soft barrel is compressed, the first reinforcing grooves can enhance the strength of the barrel bottom, so that the barrel bottom is prevented from deforming during compression. The invention further provides a vacuum fresh-keeping water taking device.

Description

technical field [0001] The invention relates to the technical field of packaged water, in particular to a disposable vacuum fresh-keeping soft barrel and vacuum fresh-keeping water fetching equipment. Background technique [0002] With the improvement of people's quality of life, drinking water barrels can be designed in a shrinkable form during the production of bottled water. During the use of the shrinkable drinking water bucket, as the drinking water in the bucket continuously flows out, the body of the drinking water bucket will be continuously compressed under atmospheric pressure, thereby preventing air from entering the inside of the drinking water bucket, Further avoid drinking water from being polluted by air during use. However, during the contraction process of the current drinking water bucket, the bottom, body and shoulder of the bucket often produce unnecessary deformation, which affects the compressibility of the drinking water bucket, and further reduces th...
