Description

Technical Field

[0001] The utility model relates to the technical field of nozzle bags, in particular to a laser film nozzle bag. Background Art

[0002] The spout bag, such as a soft packaging bag or a stand-up bag, is usually made of plastic. The spout bag is a new type of beverage and jelly packaging bag developed on the basis of the stand-up bag. The structure of the spout bag is mainly divided into two parts: the spout and the bag body. The bag body is consistent with the ordinary four-edge stand-up bag in structure, but generally uses composite materials to meet the requirements of different food packaging. The spout part can be regarded as a general bottle mouth with a straw. The two parts are closely combined to form a beverage packaging that supports sucking. Moreover, since it is a soft packaging, there is no difficulty in sucking. After sealing, the contents are not easy to shake. It is a very ideal new beverage packaging. The biggest advantage of the spout bag over the common packaging form is portability. The spout bag can be easily put into a backpack or even a pocket, and the volume can be reduced as the contents are reduced, making it more convenient to carry.

[0003] However, because the bag body of the spout bag is usually made of plastic and other materials, it has no pressure resistance to the outside world. When the bag body is squeezed, it will cause great pressure on the spout. In order to avoid damage to the spout due to great pressure, the manufacturer has strengthened the connection between the spout and the bottle cap. The consequence of this strengthening is that the bottle cap of the spout bag is more difficult to twist out than the bottle cap of an ordinary mineral water bottle, which is inconvenient for consumers with weak hand strength (the main consumer group of the spout bag is children). At the same time, the spout bag has a threaded design, which affects the comfort of children when sucking fluid food. Since the bottle cap of the spout bag is relatively small and children are careless and cause the bottle cap to be lost, the spout bag is in an open state, which can easily cause the food inside the spout bag to deteriorate or cause the food inside the bag to flow out after being accidentally compressed.

[0004] In the published Chinese patent application, publication number: CN208897665U, patent name: A spout bag with high sealing strength. Although the arrangement of the first fixing plate and the second fixing plate effectively reduces the leakage and spillage of the spout bag, the first fixing plate is an irregular triangle and is an integrated structure with the fixing cap. Due to the special shape of the first fixing plate, the gap between the fixing cap and the inner bag is reduced when the seal is fixed, making the sealing and fixing more convenient, while reducing the leakage of the spout bag. This prior art installs a fixing plate at the bottom of the bag body to keep the bag body standing, and strengthens the stability of the bag body to prevent the contents inside the bag from spilling. However, spout bags are mostly packaging bags for children's fluid food. Children are active and lively, which can easily cause the bag body to tip over and the bottle cap to be lost, causing the fluid food inside the spout bag to flow out.

[0005] Therefore, in order to solve the problems existing in the prior art: 1. The bottle cap of the spout bag is lost, and the spout bag is overturned or compressed, and the fluid food inside leaks out. 2. The spout bag has a threaded design, which affects the comfort of children when sucking fluid food. Utility Model Content

[0014] Optionally, a blocking line is provided on the inner wall of the nozzle portion.

[0015] Optionally, the bottom sheet and the two side sheets are both made of laser film.

[0016] (III) Beneficial effects

[0017] The utility model provides a laser film nozzle bag, which has the following beneficial effects:

[0018] 1. The laser film suction spout bag, through the setting of the fixed component, has the effect of preventing the contents in the bag from flowing out. The first through hole is closed by the slide, that is, the food flow channel is blocked. When the food inside the suction spout bag needs to be eaten, the pressure strip is pressed during sucking, and the pressure strip pushes the slide to slide. The slide gives way after sliding, so that the first through hole is connected with the second through hole, that is, the flow channel is opened, and the fluid food inside the suction spout bag flows through the flow channel; after stopping sucking, the pressure strip is released, and the slide is reset to block the flow channel, thereby realizing the opening or closing of the flow channel of the suction spout bag. The setting of the fixed component can effectively prevent the leakage of the internal fluid food after the suction spout bag is tipped over or pressurized.

[0019] 2. The laser film spout bag, through the setting of the slide plate, uses the slide plate to seal the spout bag once, which greatly improves the compressive strength of the spout bag, so that the spout bag can prevent leakage under pressure without relying on strengthening the thread connection strength of the bottle cap. The laser film spout bag mainly relies on the slide plate for closure, thereby reducing the connection strength between the spout bag and the bottle cap, preventing consumers with weak hand strength from being unable to open the bottle cap.

[0020] 3. The laser film nozzle bag has the effect of improving the comfort of the nozzle through the setting of the nozzle. After the thread connection strength between the nozzle and the screw cap is reduced, the number of threads between the nozzle and the screw cap can be appropriately reduced; by movably installing the nozzle part on the upper end of the thread part, the nozzle part has a certain flexibility, which can greatly improve the comfort of children when sucking. The nozzle part is movably installed on the thread part, and when in use, the nozzle part can be removed as needed.

[0021] 4. When the laser film nozzle bag is used to hold liquid food with fruit particles, in order to prevent young children from being choked by the fruit particles, a blocking line is set on the inner wall of the nozzle to block the fruit particles and prevent the young children from inhaling the fruit particles. The young children can only suck the liquid food, thereby improving the safety of the young children when sucking the nozzle bag. When the blocking line is not needed, the blocking line can be cut off, and the fruit particles can be sucked at this time. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figures 1 to 8 The utility model provides a technical solution: a laser film suction nozzle bag, comprising a fixing component 2, a suction nozzle 4, a bottom sheet and two side sheets 1. The two side edges of the two side sheets 1 are fixedly connected by hot pressing; the four peripheral edges of the bottom sheet are fixedly connected with the bottom edges of the two side sheets 1 by hot pressing, and the bottom sheet and the two side sheets 1 are fixedly connected by hot pressing to form a bag body with a cavity inside. The suction nozzle 4 is threadedly connected with a screw cap 3.

[0035] The bottom sheet and the two side sheets 1 are fixedly connected by hot pressing to form a hot pressing belt 101, which is also the edge sealing of the bag.

[0036] The fixing assembly 2 is arranged on the upper part of the bag body, and the fixing assembly 2 includes a fixing block 201 and a slide plate 204. A hot pressing area 203 is engraved on the outer wall of the fixing block 201, and the hot pressing area 203 on the fixing block 201 is fixedly connected with the upper edge of the bag body by hot pressing. The fixing block 201 is provided with a first through hole 205 that is connected to the inner cavity of the bag body, and the slide plate 204 is slidably arranged inside the fixing block 201. The slide plate 204 is provided with a second through hole 208. After the slide plate 204 slides, the second through hole 208 is connected with the first through hole 205. The middle part of the suction nozzle 4 is provided with a third through hole 403, and the suction nozzle 4 is arranged on the fixing block 201, and the third through hole 403 is connected with the first through hole 205.

[0037] Among them, the first through hole 205 and the third through hole 403 are interconnected, and the two together constitute a flow channel, and the flow channel is connected to the internal cavity of the bag body. The slide plate 204 is used to block the flow channel. After the slide plate 204 slides, the second through hole 208 on the slide plate 204 is connected to the flow channel, and the second through hole 208 is located at the flow channel, and the flow channel is in an open state at this time. Through the setting of the slide plate 204, the slide plate 204 is used to close the spout bag once, which greatly improves the compressive strength of the spout bag at the bag mouth, so that the spout bag can prevent leakage under pressure without relying on strengthening the threaded connection strength of the screw cover 3. The laser film spout bag mainly relies on the slide plate 204 for closure, thereby reducing the connection strength between the spout 4 of the spout bag and the screw cover 3, and preventing consumers with weak hand strength from being unable to open the screw cover 3.

[0038] The suction nozzle 4 is composed of a threaded portion 401 and a nozzle portion 402. The nozzle portion 402 is movably mounted on the upper end of the threaded portion 401. The nozzle portion 402 is made of a rubber material or a latex material, and has a certain degree of flexibility.

[0039] After the thread connection strength between the suction nozzle 4 and the screw cap 3 is reduced, the number of thread turns between the suction nozzle 4 and the screw cap 3 can be appropriately reduced. By movably installing the nozzle part 402 on the upper end of the threaded part 401, the nozzle part 402 has a certain flexibility, which can greatly improve the comfort of the child when sucking. The nozzle part 402 is movably installed on the threaded part 401. When in use, the nozzle part 402 can be removed according to actual needs.

[0040] Specifically, a slide groove is provided inside the fixed block 201, and the slide plate 204 is slidably arranged in the slide groove of the fixed block 201. A slideway is provided on the fixed block 201, and a pressure strip 202 is installed on the slideway of the fixed block 201, and the slideway is connected with the slide groove, and a second spring 207 is provided in the slideway, one end of the second spring 207 is fixedly connected to the pressure strip 202, and the other end of the second spring 207 is fixedly connected to one end of the slide plate 204, and the other end of the slide plate 204 is fixedly connected to the first spring 206.

[0041] Among them, the rigidity of the second spring 207 is greater than that of the first spring 206, and the first spring 206 can shrink deeply after being compressed. The first through hole 205 is closed by the slide plate 204, that is, the food flow channel is blocked. When the fluid food inside the spout bag needs to be eaten, the pressure strip 202 is pressed while sucking, and the pressure strip 202 pushes the slide plate 204 to slide. The slide plate 204 gives way after sliding, so that the first through hole 205 is connected with the second through hole 208, that is, the flow channel is opened, and the fluid food inside the spout bag flows through the flow channel; after stopping sucking, the pressure strip 202 is released, and the slide plate 204 resets the blocked flow channel, thereby realizing the opening or closing of the spout bag flow channel. Through the setting of the fixing component 2, it can effectively prevent the leakage of the fluid food inside the spout bag after it is tipped over or compressed.

[0042] More specifically, a plurality of rubber sealing strips are provided at the sliding connection between the slide plate 204 and the fixed block 201 .

[0043] A plurality of rubber sealing strips are provided at the sliding connection between the slide plate 204 and the fixed block 201 to prevent fluid food from entering the slide groove.

[0044] The laser film suction spout bag shown in this technical solution is not only used for children's fluid food packaging, but also for fluid food packaging for people of all ages. The laser film suction spout bag shown in this technical solution is not only used for holding fluid food, but also for holding fluid food containing granular food, and can be used for holding powdered and granular food. The laser film suction spout bag shown in this technical solution is not limited to holding food, but also suitable for holding all fluid commodities, and suitable for holding powdered and granular commodities.

[0045] When in use (when the laser film nozzle bag contains fluid food): 1. Rotate and twist the screw cap 3 to separate the screw cap 3 from the nozzle 4.

[0046] 2. The consumer presses the pressure strip 202 with his hand, and the pressure strip 202 pushes the second spring 207. The second spring 207 pushes the slide plate 204 to slide. The slide plate 204 compresses the first spring 206. The slide plate 204 gives way after sliding, and the second through hole 208 is connected with the first through hole 205, so that the flow channel is opened.

[0047] 3. The consumer sucks the nozzle 402 (when the nozzle 402 is not needed, the nozzle 402 can be removed) to eat the food inside the nozzle bag.

[0048] Fourth, after eating, release the pressure strip 202, and under the elastic push of the first spring 206, the slide plate 204 is reset, and the slide plate 204 blocks the flow channel. Then, the screw cap 3 is rotated and screwed onto the suction nozzle 4. Embodiment 2

[0049] See also Figures 1 to 8The main difference between this embodiment and the first embodiment is that the upper parts of the two side sheets 1 are hot pressed to form handle loop holes 102. The bottom sheet and the two side sheets 1 are both made of laser film.

[0050] The handle loop 102 is used for the convenience of consumers to carry the bag. The bag body can also be made of kraft paper, plastic and other materials.

[0051] A blocking line 404 is disposed on the inner wall of the nozzle portion 402 .

[0052] When the laser film nozzle bag is used to hold a liquid food with fruit particles, in order to prevent a child from being choked by the fruit particles, a blocking line 404 is provided on the inner wall of the nozzle 402 to block the fruit particles, thereby preventing the child from inhaling the fruit particles. The child can only suck the liquid food, thereby improving the safety of the child when sucking the nozzle bag. When the blocking line 404 is not needed, the blocking line 404 can be cut off, and the child can then suck the fruit particles.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
