Description

milk box

technical field

The invention belongs to the field of liquid beverage packaging, in particular to a milk packaging box.

Background technique

Milk is an indispensable drink in our daily life. Currently, the packaging bags used for packaging milk are divided into soft and hard materials. Among them, soft packaging is not conducive to stacking and has a low utilization rate of the inner space of the full box packaging box, while hard packaging is good for full box packaging and the utilization of the inner space of the box. The rate reaches more than 98%, so more hard packaging is used. However, due to the use of hard packaging, milk will remain on the inner wall of the packaging box during the consumer's use, causing part of the milk to be wasted. When milk is packaged in the existing rigid packaging, a layer of leak-proof coating film is provided on the inner wall, and the coating film generally contains metal materials, which increases the cost of the rigid packaging.

Contents of the invention

In order to overcome the deficiencies of the existing milk packaging, the present invention provides a milk packaging box.

Technical scheme of the present invention is:

A milk packaging box, the packaging box includes soft packaging and hard packaging, the soft packaging is arranged inside the hard packaging, the soft packaging is close to the inner wall of the hard packaging, and the space between the flexible packaging and the hard packaging is movable.

The soft package is provided with a straw, which is inserted into the interior of the soft package, and the hard package is provided with a suction port, through which the straw extends out of the hard package.

The part of the straw exposed outside the hard package and the part not protruding from the suction port are folded at the suction port; the part of the straw exposed outside the hard package is folded and pasted on the surface of the hard package by double-sided tape.

The joint between the flexible package and the straw is sealed.

The portion of the straw exposed outside the hard package and the sterilized sealing film of the suction port will be sealed.

The straw is sealed inside the fold by a sealing film.

The shape of the sealing film is the same as the internal cross-sectional shape of the straw at the folding place.

The sealing film is provided with a pre-destruction line, and the thickness of the portion of the sealing film where the pre-destruction line exists is smaller than the thickness of other parts of the sealing film.

The pre-destruction line is drawn on the surface of the sealing film by means of material removal, and the planar projection shape of the pre-destruction line can be a square, a cross, an X or a line.

The invention has the following beneficial effects: in the process of use by consumers, the milk remaining on the inner wall of the packaging box can be reduced, and the waste of milk is greatly reduced. Since the inner wall of the rigid packaging of the present invention has no leak-proof coating film, the production cost of the rigid packaging is reduced.

Description of drawings

Fig. 1 is a sectional view of a milk packaging box according to a specific embodiment of the present invention;

Among them, 1 is soft packaging, 2 is hard packaging, 3 is straw, and 4 is suction port.

Detailed ways

Referring to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention include the shape, structure, mutual position and connection relationship of each part, the function and working principle of each part, and the manufacturing process of the various components involved. And the method of operation and use, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

As shown in Figure 1, the milk packaging box includes soft packaging 1 and hard packaging 2. The soft package 1 is arranged inside the hard package 2 , and the soft package 1 is close to the inner wall of the hard package 2 . Soft pack 1 contains milk. In order to extract the milk in the soft package 1 , the soft package 1 is provided with a straw 3 , and the straw 3 is inserted into the inside of the soft package 1 . The hard package 2 is provided with a suction port 4, and the straw 3 extends out of the hard package 2 through the suction port 4. In order to reduce the space occupied by the milk packaging box when it is not in use, the part of the straw 3 that is exposed outside the hard package 2 and the part that does not protrude from the suction port 4 are folded at the suction port 4 . The part of the straw 3 exposed outside the hard packaging 2 is folded and pasted on the surface of the hard packaging 2 with double-sided tape. For sanitation, the portion of the straw 3 exposed outside the hard package 2 and the suction port 4 are sealed with a sterilized sealing film 5 . In order to prevent the milk in the soft package 1 from overflowing the soft package 1 through the joint between the soft package 1 and the straw 3 , the joint between the soft package 1 and the straw 3 is sealed. In order to prevent the milk in the soft package 1 from overflowing through the joint of the straw 3, the inside of the folded straw 3 is sealed with a sealing film. The shape of the sealing film is the same as the internal cross-sectional shape of the straw 3 at the fold. When the straw 3 changes from the folded state to the open state, due to the change of the internal cross-sectional shape and the increase of the cross-sectional area at the folded place, the sealing film is destroyed, and the straw 3 changes from the closed state to the open state, and the user can suck the soft package 1 through the straw 3 milk inside. In order to increase the success rate of the sealing film being destroyed when the straw 3 changes from the folded state to the open state, we set a pre-destruction line on the sealing film. The pre-destruction line is drawn on the surface of the sealing film by removing materials. The thickness of the part where the pre-destruction line exists on the film is smaller than the thickness of other parts of the sealing film. The planar projection shape of the pre-destruction line can be in the shape of a rice, a cross, an X or a straight line.

In order to fully absorb the milk in the soft package 1, especially the milk hanging on the inner wall of the soft package 1, the space between the soft package 1 and the hard package 2 is movable. The space between the soft package 1 and the hard package 2 enters the space between the soft package 1 and the hard package 2. Due to the effect of atmospheric pressure, the volume of the soft package 1 will decrease, and the milk in the compressed soft package 1 enters the user’s mouth through the straw 3, which reduces the hanging on the inner wall of the soft package 1. The role of milk.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned method, as long as various insubstantial improvements are adopted in the method concept and technical solutions of the present invention, or there is no improvement Directly applying the concept and technical solutions of the present invention to other occasions is within the protection scope of the present invention.
