Description

Technical Field

[0001] The utility model relates to the field of sauce packaging, in particular to a commercial sauce packaging bag. Background Art

[0002] Sauce has become one of the indispensable condiments in the packaged food industry, pastry industry, and catering industry. Existing commercial sauce packaging bags generally use ordinary three-side sealed packaging bags and suction spout bags. The three-side sealed packaging bags have a simple structure and are convenient for packaging and discharging, but are not convenient for sealing and storing unused sauces, and are not convenient for squeezing the sauce out of the bag; although the suction spout bag is convenient for sealing and storing unused sauces, it is also not convenient for cleaning the sauce out of the bag; and the packaging volume of a single commercial sauce bag is generally heavy. Using three-side sealed packaging bags and suction spout bags requires workers to manually turn the packaging bag upside down to pour out the sauce, which is labor-intensive for workers. Utility Model Content

[0003] The purpose of the utility model is to overcome the above problems existing in the prior art and provide a commercial sauce packaging bag.

[0004] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] Furthermore, an adhesive tape is pasted on the outer surface of the reverse bag film at the junction of the nozzle and the accommodating cavity.

[0007] Wherein, a separation opening for conveniently separating the front bag film from the back bag film is reserved at one end between the front bag film and the back bag film close to the second metal flat bar.

[0008] The projection of the easy-tear opening is located on the second metal flat bar, and the connecting line of the two easy-tear openings is parallel to the long axis of the second metal flat bar.

[0009] The length of the first metal flat strip is greater than the width of the front bag film, and the length of the second metal flat strip is greater than the width of the front bag film at the nozzle.

[0010] Furthermore, the corners of the first metal flat bar and the corners of the second metal flat bar are both rounded.

[0011] Furthermore, the surface of the first metal flat bar and the surface of the second metal flat bar are both provided with a polytetrafluoroethylene coating.

[0012] The beneficial effects of the present invention are as follows: the outer contour of the front bag film and the outer contour of the back bag film are fixed together to form a connected accommodating cavity and a material spout between the front bag film and the back bag film, and the long side of the material spout is separated from the accommodating cavity, which is convenient for placing the cavity part of the sauce packaging bag flat on a support, and discharging the sauce by deflecting the material spout downward, thereby reducing the labor intensity of the staff; a first metal flat strip is pasted on the bottom outer surface of the front bag film, and the sauce packaging bag is rolled up from the bottom by using the first metal flat strip, so that the sauce in the sauce packaging bag can be squeezed out conveniently; a second metal flat strip is pasted on the upper outer surface of the front bag film, and the unused sauce is sealed and stored by using the second metal flat strip.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] like Figures 1 to 5As shown, a commercial sauce packaging bag includes a "б"-shaped front bag film 1 and a "б"-shaped back bag film 2. The outer contour of the front bag film 1 and the outer contour of the back bag film 2 are fixed together to form a sealed edge 3. A receiving cavity 4 for receiving sauce and a material spout 5 for entering and exiting sauce are formed between the front bag film 1 and the back bag film 2. The receiving cavity 4 is connected to the short side of the material spout 5, and the long side of the material spout 5 is separated from the receiving cavity 4, which makes it convenient to place the cavity part of the sauce packaging bag flat on a support, and discharge the sauce by deflecting the material spout downward, thereby reducing the labor intensity of the staff.

[0022] A first metal strip 6 for winding is attached to the bottom outer surface of the front bag film 1. The strip is longer than the width of the front bag film 1. To prevent the corners of the strip from scratching the sauce bag, the strip has rounded corners. To prevent corrosion, the strip is coated with polytetrafluoroethylene. The strip is used to wind the sauce bag from the bottom, facilitating the extrusion of the sauce from the bag.

[0023] A second metal strip 7 for sealing is attached to the upper outer surface of the front bag film 1. The strip's length is greater than the width of the front bag film 1 at the spout. To prevent the strip's corners from scratching the sauce bag, the strip's corners are rounded. To prevent corrosion, the strip is coated with polytetrafluoroethylene. This second strip seals and preserves unused sauce.

[0024] Two symmetrical easy-tear openings 8 are provided on the top of the back bag film 2, and the projection of the easy-tear openings 8 is located on the second metal flat bar 7. The connecting line of the two easy-tear openings 8 is parallel to the long axis of the second metal flat bar 7. A separation opening 10 is reserved between the front bag film 1 and the back bag film 2 at one end close to the second metal flat bar 7 for conveniently separating the front bag film 1 from the back bag film 2. The front bag film 1 and the back bag film 2 are separated from the separation opening until the easy-tear opening, and the back film bag 2 is torn off from the position of the easy-tear opening 8, thereby opening the material nozzle 5 so that the sauce can be discharged.

[0025] The outer surface of the back bag film 2 is adhered with tape 9 at the junction of the nozzle 5 and the accommodating cavity 4 to improve the strength of the back bag film 2 at the junction of the nozzle 5 and the accommodating cavity 4 and prevent the back bag film 2 and the front bag film 1 from being torn when the nozzle is deflected relative to the accommodating cavity.

[0026] The sauce packaging bag has a filling port reserved at the bottom for filling the sauce when the packaging bag is produced. After the sauce filling is completed, the filling port is sealed and fixed by a bag sealing machine and connected to the sealing edge 3 as a whole.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
