The utility model discloses a standing pouch sealing and leakage-proof improvement structure, which comprises a bottom portion and a pouch body, when unfolding the bottom portion, the pouch body can stand, at the corresponding crossing position of a left sealing portion of the bottom portion and a left sealing portion of the pouch body, the horizontal width of the left sealing portion of the bottom portion is larger than that of the left sealing portion of the pouch body, the crossing position of the left sealing portion of the bottom portion extends towards the pouch body and is sealed at the pouch body to form a left extending sealing portion, the left extending sealing portion is crossed at the inner side of the left sealing portion of the pouch body, further, at the corresponding crossing position of a right sealing portion of the bottom portion and a right sealing portion of the pouch body, the horizontal width of the right sealing portion of the bottom portion is larger than that of the right sealing portion of the pouch body, and the crossing position of the right sealing portion of the bottom portion extends towards the pouch body and is sealed at the pouch body to form a right extending sealing portion, and the right extending sealing portion is crossed at the inner side of the right sealing portion of the pouch body, thereby enabling a sealing surface near the junction of the left and right sealing portions of the bottom portion of the pouch and the left and right sealing portions of the two-layered pouch body to be increased, increasing the sealing and leakage-proof property without affecting the capacity of the pouch, and simultaneously keeping overall appearance.

Description

Improved sealing leak-proof structure for self-standing bag
Technical field
The utility model relates to a kind of self-support bag involution leakage-proof structure.
Background technology
The Self stand bag packing is present a kind of packaged form all the fashion, and it has good counter display effect, can greatly increase product to client's attraction.
Yet, understand the self-support bag packaged form that uses in the market according to the applicant and have following defective: since packaging bag itself exist four floor district, bottom with bag two-layer district of body, be the zone of the different numbers of plies, make four floor district and two-layer district intersection material thickness be stepped appearance and change, involution requires high like this.The bottom left and right involution section (being four floor district) of existing Self stand bag is the same with the corresponding intersection width of the left and right involution of bag body section (for two-layer district), and near the sealing surface its bottom four floor district left and right involution section and the bag two-layer district of body left and right involution section have a common boundary like this is narrow.And four floor district, the bottom left and right involution section after the packing and the bag two-layer district of body left and right involution section intersection stress are concentrated stressed big, cause that easily involution destroys, the left and right involution form in bottom of therefore existing Self stand bag has been subjected to certain limitation in the application facet of flexible package, and is easily damaged.
Summary of the invention
In order to overcome defects, the utility model provides a kind of improved sealing leak-proof structure for self-standing bag, and this improved sealing leak-proof structure for self-standing bag can effectively strengthen the involution fastness of four floor district, bottom and the two-layer district of bag body intersection, and range of application is wider, not cracky.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of improved sealing leak-proof structure for self-standing bag, comprise the bottom, the bag body, a bag body left side, right both sides involution together, form a two-layer bag body left side, right two involution sections, bottom periphery is connected in a bag body under shed, left in the bottom, right dual-side is interior left with the bag body, the corresponding involution of right dual-side, it is left to form the bottom, right two involution sections, the bottom is recessed in bag body under shed, the bottom can make bag upright when launching, the corresponding intersection of left involution section and the left involution of bag body section in the bottom, the left and right sides width of bottom left involution section is greater than the left and right sides width of the left involution of bag body section, and involution is extended to the bag body in the intersection of the left involution in bottom section, forms left extension involution section, and left extension involution section intersects at the left involution of bag body section inboard;
The corresponding intersection of right involution section and the right involution of bag body section in the bottom, the left and right sides width of bottom right involution section is greater than the left and right sides width of the right involution of bag body section, and involution is extended to the bag body in the intersection of the right involution in bottom section, form right extension involution section, right extension involution section intersects at the right involution of bag body section inboard;
So that near the sealing surface the bottom of packaging bag left and right involution section and the left and right involution of the two-layer bag body section intersection increases, promote the involution leak resistance like this, and the not obvious capacity that affects packaging bag, and keep overall appearance.
Further technical scheme of the present utility model is:
The forward and backward side of bottom periphery is integrally formed at bag forward and backward side of body under shed.
The forward and backward side seal of bottom periphery closes and is connected in bag forward and backward side of body under shed.
The forward and backward both sides correspondence of bottom left and right involution section fits together, and also can not fit fully.
Local correspondence fits together in the forward and backward both sides of bottom left and right involution section.
The beneficial effects of the utility model are: since left and right extension involution section respectively with left and right two-layer inboard intersecting of involution section of bag body, this sample example energy is so that the left and right involution in packaging bag bottom section increases with near bag sealing surface that the corresponding intersection of the left and right involution of body section is, involution place fastness is strong, but Integral lifting involution leak resistance.And the not obvious capacity that influences packaging bag, and can keep overall appearance.
