Description

Technical Field

[0001] The invention relates to the field of electronic product accessories, and in particular to a pet feeding combination bag and a preparation method thereof. Background Art

[0002] At present, many people like to bring their pets (including but not limited to dogs and cats) when traveling. Pets need to be fed when traveling with people. In order to ensure that the pets can eat and drink water in time, people who travel usually choose to purchase a combination container as shown in patent publication document CN212697136U. The combination container of this structure mainly includes a base for support and three bowls, wherein the support base and the three bowls are hard structures, so the combination container of this structure cannot be compressed when carried, and the volume is relatively large, which causes many inconveniences when carrying. Summary of the invention

[0003] In view of the above problems, the present invention proposes a pet feeding combination bag, which is composed of two self-supporting bags and a connecting cylinder. The entire combination bag is a self-supporting bag made of flexible material and can be coiled or folded for storage before use. When it is needed, it only needs to be torn along the first tearable breaking line or the second tearable breaking line to form two self-supporting bags.

[0004] The technical solution adopted by the present invention is as follows: A pet feeding combination bag comprises a first self-supporting bag body, a second self-supporting bag body and a connecting cylinder body, wherein the first self-supporting bag body is a bag body made of a flexible material, the second self-supporting bag body is a bag body made of a flexible material, the connecting cylinder body is a connecting cylinder body made of a flexible material, the two ends of the connecting cylinder body are respectively connected to the bag opening of the first self-supporting bag body and the bag opening of the second self-supporting bag body, a first easy-tear fracture line is arranged between the first self-supporting bag body and the connecting cylinder body, and a second easy-tear fracture line is arranged between the second self-supporting bag body and the connecting cylinder body.

[0005] In this combination bag, the first self-supporting bag body and the second self-supporting bag body are essentially self-supporting bags, and the first self-supporting bag body, the second self-supporting bag body and the connecting cylinder body are all made of a single plastic film or composite film. This combination bag is generally in a sheet shape before use, and can be rolled or folded as needed.

[0006] The specific method of using the combination bag is as follows: when using, the first self-supporting bag body and the connecting cylinder body are torn apart along the first tearable rupture line, or the second self-supporting bag body and the connecting cylinder body are torn apart along the second tearable rupture line, so that the entire combination bag can be disassembled into two self-supporting bags. The two self-supporting bags can be placed on a flat ground, one of the self-supporting bags (called bag A) is used to store water for pets to drink, and the other self-supporting bag (called bag B) is used to store food for pets to eat. After use, the water in the self-supporting bag (i.e. bag A) is poured out, and then the self-supporting bag (i.e. bag B) containing food is rolled up and stored together with the food. After bag B is rolled up and stored, it can be inserted into bag A and discarded or saved for feeding next time.

[0007] Specifically, after the combination bag is torn into two self-supporting bags, the connecting cylinder can be connected to the first self-supporting bag body, the connecting cylinder can also be connected to the second self-supporting bag body, or the connecting cylinder is neither connected to the first self-supporting bag body nor to the second self-supporting bag body (i.e. directly discarded).

[0008] In summary, this combination bag consists of two self-supporting bags and a connecting cylinder. The entire combination bag is a self-supporting bag made of flexible material. It can be wrapped or folded for storage before use. When it is needed, it only needs to be torn along the first tearable breaking line or the second tearable breaking line to form two self-supporting bags.

[0009] Optionally, a first tearable opening is provided at one end of the first tearable fracture line, and a second tearable opening is provided at one end of the second tearable fracture line.

[0010] The first easy-tear opening and the second easy-tear opening are provided to play a guiding role, so as to facilitate tearing along the first easy-tear fracture line or the second easy-tear fracture line.

[0011] Optionally, the first easy-tear opening is a triangular first easy-tear opening, and the second easy-tear opening is a triangular second easy-tear opening.

[0012] Optionally, the first self-supporting bag body and the second self-supporting bag body are consistent in shape and size.

[0013] Optionally, the first easy-tear fracture line and the second easy-tear fracture line are in parallel.

[0014] Optionally, the first tearable fracture line is a straight first tearable fracture line.

[0015] Optionally, the second tearable fracture line is a straight second tearable fracture line.

[0016] Optionally, the bag wall thickness of the first self-supporting bag body is the same as the bag wall thickness of the second self-supporting bag body.

[0017] A method for preparing the pet feeding combination bag as described above comprises the following steps: It comprises side pieces and bottom pieces, wherein the side pieces are at least 2 pieces, the bottom pieces are at least 2 pieces, the side pieces are planar side pieces, and the bottom piece is a U-shaped bottom piece; One side of the two bottom sheets is fixed to the two ends of one side sheet by heat bonding, and then the other side sheet is fixed to the bottom sheet and the side sheet by heat bonding.

[0018] Optionally, a triangular tearable notch is provided on the side panel, and holes arranged in a linear pattern are opened on the side panel, and the holes arranged in a linear pattern are provided in two rows.

[0019] Specifically, each side panel has two easy-tear openings, namely a first easy-tear opening and a second easy-tear opening, and the two rows of holes arranged in a linear shape are respectively a first easy-tear fracture line and a second easy-tear fracture line.

[0020] Specifically in this type of combination bag, the tearable opening and the hole can be opened on the side panel before heat sealing, or can be opened after heat sealing is completed. A combination bag has two side panels, the first tearable fracture lines on the two side panels are in an overlapping state, the second tearable fracture lines on the two side panels are in an overlapping state, and the first tearable opening and the second tearable opening on the two side panels are also in an overlapping state.

[0021] Optionally, two ends of the bottom sheet are provided with through-notches, and the two side sheets are directly heat-sealed together at the through-notches.

[0022] In this combination bag, since the two sides of each bottom film need to be heat-sealed with the two side films respectively, the bottom film is equivalent to separating the two side films, and the bottom film plays a spacing role. Due to the spacing effect of the bottom film, the two side films cannot be heat-sealed together at the heat-sealed place between the bottom film and the side films, so a through-notch is opened on the bottom film, and with the help of the through-notch, the two side films at the heat-sealed place can be heat-sealed together.

[0023] Optionally, the side sheets include a PET film, an aluminum foil and a PE film, and the PET film and the PE film are respectively located on both sides of the aluminum foil; the bottom sheet includes a PET film, an aluminum foil and a PE film, and the PET film and the PE film are respectively located on both sides of the aluminum foil.

[0024] Specifically, the bottom sheet and the side sheets of this combination bag are made of the same composite film, which is composed of PET film, aluminum foil and PE film, wherein the PE film and the PET film are respectively located on both sides of the aluminum foil, and the PET film in this composite film is used as the outer wall surface, and the PE film is used as the inner wall surface. When this composite film is used to prepare bags, the PE film is used as the heat-sealing surface. Therefore, after this composite film is prepared into a combination bag, the PE film is located on the inner wall surface of the combination bag, and the PET film is located on the outer wall surface of the combination bag.

[0025] The beneficial effects of the present invention are as follows: it is composed of two self-supporting bags and a connecting cylinder, the entire combined bag is a self-supporting bag made of flexible material, can be coiled or folded for storage before use, and when needed, only needs to be torn along the first tearable fracture line or the second tearable fracture line to form two self-supporting bags.

[0046] It is important to note that Figure 1 The shaded area in the figure is the heat-sealed area.

[0047] Combined with Figure 2 As shown in the figure, a preparation method of the combination bag is provided. First, two side sheets 11 (which can be a single film sheet or a composite film sheet) and two bottom sheets 12 (which can be a single film sheet or a composite film sheet) are prepared. First, the two bottom sheets 12 are composited at the two ends of one of the side sheets 11 by heat sealing, and then the other side sheet 11 is composited with the two bottom sheets 12 by heat sealing. Finally, the edges of the two side sheets 11 are composited together (before the two side sheets are heat-sealed together, a plurality of bags of pet food can be placed in the cavity formed by the side sheets and the bottom sheets). At this time, the whole combination bag is roughly formed, and finally, a first easy-tear fracture line 201 and a second easy-tear fracture line 202 are opened by punching with a sharp needle. The first easy-tear fracture line 201 and the second easy-tear fracture line 202 are connected to the cylinder 2, and finally, a first easy-tear opening 301 and a second easy-tear opening 302 are opened. Example

[0048] Combined with Figure 2 And attached Figure 3 As shown in, the preparation method disclosed in Example 1 further discloses a method for preparing a combination bag.

[0049] A method for preparing the pet feeding combination bag as described above comprises the following steps: It includes a side piece 11 and a bottom piece 12. The side piece 11 has two pieces, and the bottom piece 12 has two pieces. The side piece 11 is a flat side piece 11, and the bottom piece 12 is a U-shaped bottom piece 12. One side of the two bottom sheets 12 is fixed to the two ends of one side sheet 11 by heat bonding, and then the other side sheet 11 is fixed to the bottom sheet 12 and the side sheet 11 by heat bonding.

[0050] The side panel 11 is provided with a triangular tear-away opening, and the side panel 11 is provided with holes arranged in a linear pattern, and the holes arranged in a linear pattern are arranged in two rows.

[0051] Specifically, each side panel 11 has two easy-tear openings, namely a first easy-tear opening and a second easy-tear opening, and the two rows of holes arranged in a linear shape are respectively a first easy-tear fracture line and a second easy-tear fracture line.

[0052] Specifically, in this type of combined bag, the tear-off opening and the hole can be opened on the side panel 11 before heat sealing, or after heat sealing. A combined bag has two side panels 11, the first tear-off lines on the two side panels 11 are in a superimposed state, the second tear-off lines on the two side panels 11 are in a superimposed state, and the first tear-off opening and the second tear-off opening on the two side panels 11 are also in a superimposed state. In order to improve the working efficiency, the preparation method disclosed in this embodiment uses the side panel 11 with the tear-off opening and the hole opened before heat sealing.

[0053] See attached Figure 3 As shown in FIG, two ends of the bottom sheet 12 are provided with through notches 121 , and the two side sheets 11 are directly heat-sealed together at the through notches 121 .

[0054] In this combination bag, since both sides of each bottom film 12 need to be heat-sealed with the two side films 11 respectively, the bottom film 12 is equivalent to separating the two side films 11, and the bottom film 12 plays a spacing role. Due to the spacing effect of the bottom film 12, the two side films 11 cannot be heat-sealed together at the heat-sealed part of the bottom film 12 and the side films 11, so a through notch 121 is opened on the bottom film 12, and with the help of the through notch 121, the two side films 11 at the heat-sealed part can be heat-sealed together.

[0055] Combined with Figure 3 As shown in the Figure 3 is a cross section of the negative film 12, Figure 3 The shaded area in the figure is the heat-sealed area between the bottom sheet 12 and the side sheet 11, and the through-notch 121 is where the two side sheets 11 are directly heat-sealed. This structure can improve the heat-sealed strength between the side sheets 11 and the bottom sheet 12 and reduce the probability of leakage during use.

[0056] The side sheet 11 includes a PET film, an aluminum foil and a PE film, and the PET film and the PE film are respectively located on both sides of the aluminum foil. The bottom sheet 12 includes a PET film, an aluminum foil and a PE film, and the PET film and the PE film are respectively located on both sides of the aluminum foil.

[0057] Specifically, the bottom sheet 12 and the side sheet 11 in this type of combination bag both use the same composite film, which is composed of PET film, aluminum foil and PE film, wherein the PE film and the PET film are respectively located on both sides of the aluminum foil, and the PET film in this composite film is used as the outer wall surface, and the PE film is used as the inner wall surface. When this composite film is used to prepare a bag, the PE film is used as a heat-sealing surface. Therefore, after this composite film is prepared into a combination bag, the PE film is located on the inner wall surface of the combination bag, and the PET film is located on the outer wall surface of the combination bag.

[0058] The above-described embodiments only express some embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for those skilled in the art, it is still possible to modify the technical solutions recorded in the above-mentioned embodiments, or to replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
