Description

A box with glue and suction combined sealing function

Technical field

The invention belongs to the technical field of packaging, and particularly relates to a packaging box with a glue and suction combined sealing function.

Background technique

With the development of globalization, the geographical boundaries are getting smaller and smaller, and the circulation of consumer goods is becoming more and more free from geographical restrictions. Many brand products are sold globally. Some products are sensitive to moisture. After opening a bag in a dry climate, the product is prone to lose moisture quickly. After opening the bag in a humid climate, the product is prone to moisture and mildew, which affects the quality of the product. In addition, the smell and aroma of the product itself It is also easy to volatilize after opening the package, which affects the quality and feeling of the product during consumption.

Many product packaging cannot be reversibly restored after opening the package. For example, soft pack cigarettes, soft packs break the closed structure after unpacking and cannot be restored. The problem of quick-drying and resurgence is particularly prominent. After consumers purchase soft-packed cigarettes, most consumers will tear off the aluminum foil wrapping paper on the top side of the soft-packed cigarette. The packaging structure will be irreversibly damaged. After the cigarette is exposed, the moisture is easily changed and it is also susceptible to pollution. And the cigarettes are easy to fall out. Due to the low stiffness of the soft pack cigarettes, as the cigarettes are continuously removed, the package gradually loses its inner support, and the box body is prone to deformation. When stored, the cigarettes are easily crushed and damaged, resulting in secondary quality. The problem is that the consumer experience is bad.

Another example is the crispy food such as “chips”, which cannot be recovered after opening the package. If the “chips” are not consumed once, the remaining “chips” will quickly absorb the moisture and cause a poor consumption experience.

In view of the demand for such repeatable closed packaging, various technical forms are known to be implemented. Now, such as:

Chinese patent application CN201310624084.1 discloses a soft box cigarette package with a repeated open type seal. Includes pasted open seals, liners and outer boxes. The adhesive repeating open seal comprises an edge seal, a seal and a pull tab, and the seal edge is provided with an adhesive layer, which is adhered to the front and back sides of the outer box and the inner liner paper, and the seal covers the cigarette extraction mouth, and the cigarette is extracted. The mouth is cut by the inner liner paper, and the pull tab has no adhesive layer, and the pull-tab is opened upward to expose the cigarette extraction opening. The soft-packed cigarette package with the repeated open-opening seal can seal and protect the opened cigarette, and the sealing effect is good, which effectively ensures the moisture and odor of the cigarette after the cigarette pack is opened. However, the technical scheme of the inner liner of the wrapped cigarette is not supportive, and does not collapse when the cigarette is not extracted, but once the cigarette is taken out or the package is squeezed, the inner liner will deform and collapse downward. The closure of the liner does not effectively bond the lining area to create a gap, resulting in a loss of sealing environment and effectiveness. At the same time, the area used to uncover the seal is not glued, and the opening and curling phenomenon will be formed after repeated uncovering, and the appearance is not good. At the same time, it is difficult to remove the cigarette because its take-out is placed on top of the cigarette box.

Application No. CN201180034526.6 discloses a flexible package for cigarettes. An inner sleeve for a group of cigarettes made of a foldable packaging material for packaging contents, the inner sleeve at least substantially completely surrounding the package contents, and the inner sleeve having a large area of the front side and the back side and the front side A narrow side where the side and rear sides are connected to each other. Also having a bottom side and an upper side extending along respective sides of the substantially square package contents, and the inner sleeve is made of a foldable packaging material in the areas of the front side, the back side, the narrow side and the bottom side Surrounding the outer jacket, characterized in that the outer sleeve has an edge-side recess in the region of the front side of the inner sleeve for gripping the contents of the package, in which a glue label is placed on the flexible package Sign so that the notch can be loosely closed. The overall design of the technical solution is more complicated, and is composed of a closed inner sleeve with a window and a jacket, which consumes raw materials and brings about an increase in packaging cost. In addition, there is also a problem in that the sealing of the outlet is completed by only the sealing label. Since there is no frame support in the packaging structure, once the soft bag is deformed, the sealing layer is also deformed, thereby losing the closed environment. When used repeatedly, the bonding area will gradually reduce the viscosity, resulting in gaps and curling.

The parcel sheet is confirmed by the length and width dimension data calculated according to the quantity and arrangement order of the consumer product, and before the packaging is formed, the indentation treatment should be performed by molding in advance on the line requiring the folding position to make the sheet. The material forms an inward deformation along the indentation line prior to folding of the package, facilitating easy folding formation at higher packaging speeds. At the same time, in the next step, when the left side edge, the right side edge and the bottom edge of the preliminary forming box body are pasted, the bonding and heat sealing speed are faster under the action of the indentation, and the sealing effect is better.

When the package is pasted on three sides (the left side, the right side, and the bottom side), the sticking method is preferably a gluing method and a heat sealing method. Among them, when using the heat sealing method, the temperature of the heat sealing should be lower than the heat of the sheet or the shrinkage deformation while ensuring the sticking effect. The temperature is preferably controlled between 100 °C and 160 °C to ensure the flatness of the three sides after pasting, without causing deformation of the printed characters, figures, figures, QR codes, etc., thereby affecting product distribution and distribution. Picking, anti-counterfeiting and other functions.
