Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging bottle blanks, in particular to a bottle blank used for edible plastic packaging. Background Art

[0002] Plastic packaging bottles are a common food filling and storage container. During the processing, they are generally first injected into a preform by an injection molding machine to form a bottle blank, and then the bottle blank is stretched and heated by a bottle blowing machine and blown into shape. Finally, the bottle body required for packaging is obtained. It can safely store beverages and other types of food, has a long shelf life, and is convenient to eat.

[0003] The preform formed by injection molding generally includes a preform mouth, a preform body and a preform bottom. After containing beverages, people can open the bottle cap and drink at any time. In order to drink water conveniently, some people choose to insert a straw into the bottle body. However, the distance from the preform mouth to the bottom of the preform is generally large. If the inserted straw is short, it is easy to fall into the bottle body and is inconvenient to take out. If a long straw is prepared, it is inconvenient to package and carry, which increases the transportation cost, and thus will bring a less user-friendly experience.

[0004] According to the search, Chinese patent literature, announcement number: CN214690776U, discloses a lightweight packaging bottle blank bottom structure, by setting the bottle mouth and the bottle blank body fixedly connected, the bottle blank bottom and the bottle blank body fixedly connected, the bottle blank bottom has a mounting groove, the first sealing ring is fixedly connected to the mounting groove of the bottle blank bottom, the boss is fixedly connected to the first sealing ring, the boss has a plurality of through holes, the outer tube is fixedly connected to the boss, a plurality of return springs are respectively fixedly connected to the outer tube, the mounting tube is fixedly connected to the plurality of return springs, the second sealing ring is fixedly connected to the mounting tube, the straw is slidably connected to the second sealing ring, the return spring inside the outer tube on the boss moves the mounting tube toward the bottle mouth, reduces the distance between the bottle mouth and the bottom of the bottle blank, inserts the straw into the second sealing ring on the inner side wall of the mounting tube, the second sealing ring wraps the straw, so that the liquid in the bottle blank body can only enter through the plurality of through holes on the boss and be discharged from the straw, thereby solving the problem that the bottom structure of the packaging bottle blank increases the distance from the bottle mouth to increase the capacity, and the inserted straw is easy to fall into the bottle blank body. However, the device has some shortcomings. First, the length of the straw in the bottle body is fixed and cannot be changed according to the user's habits. When the bottom of the straw touches the bottom of the bottle blank, the top of the straw is inside the mouth of the bottle blank and cannot absorb the drinking water inside, which affects the application of drinking water at deeper depths. Secondly, a reset spring is used in the bottle blank body. When there is a problem with the internal sealing, the stored beverage will contact the spring and corrode the spring, thereby causing food safety problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1 and Figure 2In the figure, a bottle blank for edible plastic packaging includes a bottle blank mouth 1, a bottle blank body 2 and a bottle blank bottom 3. The bottle blank mouth 1 is fixedly connected to the upper side of the bottle blank body 2, and the bottle blank bottom 3 is fixedly connected to the lower side of the bottle blank body 2. The outer side of the bottle blank mouth 1 is threadedly connected with a bottle blank cover 6, and the inner side of the bottle blank body 2 is provided with a main suction pipe 4, and an auxiliary suction pipe 5 is inserted into the inner side of the upper end of the main suction pipe 4. The upper and lower ends of the outer side of the main suction pipe 4 are respectively sleeved with a limiting sleeve 1 7 and a limiting sleeve 2 8, and the upper end of the bottle blank bottom 3 is fixedly installed with a fixing ring 2 12.

[0025] See also Figure 2 A fixing ring 9 is fixedly installed on the inner upper end of the bottle body 2, and four connecting rods 13 are fixedly connected between the inner side of the fixing ring 9 and the limiting sleeve 7 in a central axis symmetrical manner.

[0026] In this embodiment, the fixing ring 9 fixes the limiting sleeve 7 to the inner upper end of the bottle body 2 through four connecting rods 13. The limiting sleeve 7 is used to ensure the smooth movement of the main suction tube 4 in the vertical direction when the main suction tube 4 moves up and down to prevent the main suction tube 4 from tilting.

[0027] See also Figure 2 Four fixing columns 10 are fixedly connected between the limiting sleeve 8 and the fixing ring 12 in a symmetrical manner along the central axis, and a filter screen 11 is arranged between every two adjacent fixing columns 10 .

[0028] In this embodiment, the second fixing ring 12 fixes the second limiting sleeve 8 to the inner lower end of the bottle body 2 through four fixing columns 10. The second limiting sleeve 8 is used to ensure the smooth movement of the main suction tube 4 in the vertical direction when the main suction tube 4 moves up and down to prevent skewing.

[0029] Working principle: when the user opens the bottle blank cover 6, the main straw 4 uses the floating force of the drinking water to make the auxiliary straw 5 extend out of the bottle blank mouth 1 for the user to use. The limiting sleeve 1 7 and the limiting sleeve 2 8 keep the main straw 4 floating straight and steadily up and down. The limiting ring 14 can limit the main straw 4 from floating upward too much. When it is necessary to lengthen the straw for use, the auxiliary straw 5 can be pulled out of the main straw 4 by part of the length. When the bottom of the main straw 4 is inserted into the bottom 3 of the bottle blank with force, the drinking water enters from the side hole 15 at the bottom of the main straw 4. The filter net 11 between the limiting sleeve 2 8 and the fixing ring 2 12 allows the drinking water to pass through and discharges impurities at the same time, so that the user can drink with more confidence. The outer packaging strip is placed between the two convex rings 17 for greater stability and is not easy to fall off.

[0030] Example 2

[0031] See also Figure 3 and Figure 5This embodiment further explains Example 1. In the figure, a limiting ring 14 is fixedly installed on the outer side of the main suction pipe 4. The limiting ring 14 is arranged on the lower side of the limiting sleeve 8, and the outer diameter of the limiting ring 14 is larger than the through hole of the limiting sleeve 8.

[0032] In this embodiment, when the bottle blank cover 6 is opened, the main straw 4 is relatively light and moves upward with the help of the buoyancy of the beverage water, so that the upper end extends out of the bottle blank mouth 1 for use by the user. At the same time, the limiting ring 14 at the bottom is restricted by the limiting sleeve 8 to prevent the main straw 4 from floating up too much and always stays inside the bottle blank body 2.

[0033] See also Figure 4 A positioning ring 16 is fixedly installed on the inner side of the upper end of the main suction pipe 4, and the bottom of the auxiliary suction pipe 5 is plugged into the positioning ring 16.

[0034] In this embodiment, the auxiliary straw 5 and the main straw 4 maintain their relative positions through friction. When the auxiliary straw 5 needs to be extended for use, the auxiliary straw 5 can be partially pulled out of the main straw 4. When it is inserted back, the positioning ring 16 can hold the auxiliary straw 5 against it to prevent the auxiliary straw 5 from being completely hidden in the main straw 4.

[0035] See also Figure 5 A side hole 15 is provided on the outer side of the bottom of the main suction pipe 4 .

[0036] In this embodiment, when the bottom of the main suction tube 4 is inserted into the bottom 3 of the bottle blank, the side hole 15 helps the drinking water to enter the main suction tube 4 .

[0037] See also Figure 1 The upper and lower ends of the outer side of the bottle body 2 are respectively fixedly mounted with convex rings 17, and the outer edges of the two convex rings 17 are smoothly arranged.

[0038] In this embodiment: a packaging strip can be pasted between two convex rings 17 on the bottle body 2. The two convex rings 17 can better limit the packaging strip to the outside of the bottle body 2 to prevent it from falling off. The outer edge of the convex ring 17 is smoothly arranged so that the user will not be scratched by the protrusions when grasping the bottle body 2.
