Description

An inner liner for a portable milk box

technical field

The utility model relates to the technical field of packaging design, in particular to a liner in a box.

Background technique

In the production and packaging process of milk, small-package milk boxes (200-250 ml) need to be packed into portable milk boxes according to a certain quantity (such as 12 packages) in a certain way so that consumers can carry them. Small packages of milk cartons require liners to be secured in hand milk crates to prevent clutter during transport. The currently used inner liners mainly include foam (not environmentally friendly) and cardboard pasted with glue (high cost), and the current forms of inner liners are all based on manual packing, which cannot adapt to the high-speed automatic packing production line. In view of this, the present invention is proposed.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an inner liner structure applied to a portable milk packing box to adapt to an automatic packing production line, improve production efficiency, protect the environment and reduce costs.

In order to solve the problems of the technologies described above, the present invention adopts the basic idea of technical solution to be:

An inner liner for a portable milk box, comprising an upper inner liner and a lower inner liner, the upper inner liner is an upper rectangular plate with four square notches at the top corners, the four square notches are close to the upper The line connecting the four top corners in the center of the rectangular plate is the upper outer crease line, and the rectangular line frame formed by the four upper outer crease lines is the upper outer crease line frame; two folding plates are arranged in parallel, and two folding plates The end faces close to one side are not adjacent; the line frame formed by the connection lines of the four vertices close to the outer sides of the upper rectangular plate of the two folding plates is the folding line frame, and the setting between the folding line frame and the upper outer crease line frame There is an upper inner crease wire frame, and the lines connecting the four corners of the upper inner crease wire frame and the four corners of the nearest folding wire frame are upper cutting lines; two of the folding wire frames are opposite to each other. The side line is the folding crease line, and the other two sides are the folding cutting lines; the distance from each side of the folding line frame to the upper inner crease line frame, the upper outer crease line frame and the sides of the upper rectangular plate is equal ; The bottom layer inner liner is a lower rectangular plate with a lower rectangular through hole in the center, four square notches are arranged on the four corners of the lower rectangular plate, and the four square notches are close to the four corners of the center of the lower rectangular plate The connecting line is the lower outer crease line, and the rectangular line frame composed of four lower outer crease lines is the lower outer crease line frame; the lower inner crease line frame is set between the lower outer crease line frame and the lower rectangular through hole, The line connecting the four corners of the lower inner crease line frame with the four corners of the nearest lower rectangular through hole is the lower cutting line; each side of the lower rectangular through hole to the lower inner crease line frame, the lower The outer crease wireframe is equidistant from each side of the lower rectangular plate.

Preferably, the upper inner liner is a three-layer corrugated paper structure.

Preferably, the thickness of the upper inner liner is 1.8-2.0mm.

Preferably, the bottom liner is a three-layer corrugated paper structure.

Preferably, the thickness of the bottom inner liner is 1.8-2.0mm.

After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

(1) The inner liner structure disclosed by the utility model is convenient for production, and the traditional foam structure and glue-bonded corrugated paper structure are abandoned. Directly through structural optimization design, only corrugated cardboard can be used to meet the packing requirements of milk cartons. The sheet-like cardboard structure before use facilitates space-saving transportation and storage, and is not easily deformed. The invention is applicable to an automatic packing production line, helps enterprises improve production efficiency, reduces costs, and is more environmentally friendly at the same time.

(2) The inner liner adopts a pre-pressed crease and then formed structure design. Before forming, it is always a sheet-shaped cardboard, which is convenient for transportation, not easy to deform, and saves space. The pre-pressed crease reshaping method can save the gluing process, save costs and be more environmentally friendly.

(3) The sheet-shaped upper inner liner and the lower inner liner are neatly stacked in a bundle, covered with plastic film or tied with cable ties, so as to facilitate storage, transportation and handling.
