Description

Technical Field

[0001] The present disclosure relates to the technical field of packaging appliances, and particularly relates to a packaging bottle for improving the stability of heat shrink packaging. Background Art

[0002] Currently, the shapes of packaging bottles for containing liquids are diverse. Among them, cylindrical and square shapes are commonly used packaging bottle shape designs in the industry, and a low-cost heat shrink film packaging method is mostly adopted for secondary packaging.

[0003] In order to highlight the characteristics and differences of products, some manufacturers have started to adopt the design of conical bottles. However, it has been found in applications that since the contact surface is limited when conical bottles are placed side by side, the wrapping force generated during the shrinkage of the heat shrink film packaging will cause the top of the bottle to tilt. As a result, the heat shrink film packaging cannot tightly wrap around the four sides of the conical bottle. Therefore, conical bottle products cannot be applied to the secondary packaging process of heat shrink film packaging and can only use expensive cartons for secondary packaging.

[0004] That is to say, the secondary packaging cost of the packaging bottles provided based on the related technologies is relatively high. Summary of the Utility Model

[0005] The purpose of the present disclosure is to provide a packaging bottle for improving the stability of heat shrink packaging, so as to solve the technical problem of high secondary packaging cost of the packaging bottles provided by the related technologies.

[0006] In a first aspect, in an embodiment of the present disclosure, there is provided a packaging bottle for improving the stability of heat shrink packaging. Along the axial direction of the packaging bottle, the packaging bottle sequentially includes: a base portion, a transition portion, a shoulder portion, and a bottle mouth portion;

[0007] The diameter of the base portion is greater than the diameter of the transition portion, the diameter of the transition portion is greater than the diameter of the shoulder portion, the diameter of the shoulder portion is greater than the diameter of the bottle mouth portion, the base portion is cylindrical, and the ratio of the height of the base portion in the axial direction of the packaging bottle to the height of the packaging bottle is greater than or equal to 0.44.

[0008] In one embodiment, a rib groove is provided on the outer wall of the base portion, and the groove width of the rib groove is greater than or equal to 5 mm and less than or equal to 12 mm;

[0009] And / or,

[0010] The groove depth of the rib groove is greater than or equal to 1 mm and less than or equal to 4.5 mm.

[0011] In one embodiment, the rib groove spirally extends on the outer wall of the base portion along the axial direction of the packaging bottle.

[0012] In one embodiment, a plurality of rib grooves are formed on the outer wall of the base portion, and the plurality of rib grooves are arranged in an array around the axis of the packaging bottle.

[0013] In one embodiment, along the extending direction of the rib groove, the groove width of the rib groove gradually decreases from the middle of the rib groove to the edge portion of the groove opening of the rib groove; and along the extending direction of the rib groove, the groove depth of the rib groove gradually decreases from the middle of the rib groove to the edge portion of the groove opening of the rib groove.

[0014] In one embodiment, the diameter of the transition portion gradually decreases in a direction away from the base portion.

[0015] In one embodiment, the diameter of the shoulder portion gradually decreases in a direction away from the transition portion.

[0016] In one embodiment, a plurality of pressure-bearing surfaces are formed on the outer wall of the shoulder portion, the plurality of pressure-bearing surfaces are arranged around the axis of the packaging bottle, and each pressure-bearing surface includes a first side connected to the bottle mouth portion, a second side connected to the transition portion, and two side edges located between the first side and the second side, and adjacent two pressure-bearing surfaces share the same side edge.

[0017] In one embodiment, the second side is arc-shaped, and the distance between the end point of the second side and the bottle mouth portion is less than or equal to the distance between any point on the second side and the bottle mouth portion.

[0018] In one embodiment, the pressure-bearing surface is a concave surface.

[0019] In this application, by setting the base portion of the packaging bottle to be cylindrical and defining that the ratio of the height of the base portion to the height of the bottle body is greater than or equal to 0.44, the area of contact between the packaging bottle and the heat-shrinkable film during heat sealing is increased, thereby increasing the limiting effect of the heat-shrinkable film on the packaging bottle, and the problem that the tops of multiple packaging bottles are inclined due to the wrapping force during the heat-shrinkable film wrapping process can be avoided. Therefore, the secondary packaging process using the heat-shrinkable film can be supported to replace the secondary packaging process using cartons, and the secondary packaging cost of the packaging bottle can be greatly reduced.

[0022] Hereinafter, the technical solutions in the embodiments of the present disclosure will be described with reference to the accompanying drawings in the embodiments of the present disclosure.

[0023] An embodiment of the present disclosure provides a packaging bottle for improving the stability of heat shrink packaging, such as Figure 1 shown, along the axial direction of the packaging bottle, the packaging bottle sequentially includes: a base portion 10, a transition portion 20, a shoulder portion 30, and a bottle mouth portion 40;

[0024] The diameter of the base portion 10 is greater than the diameter of the transition portion 20, the diameter of the transition portion 20 is greater than the diameter of the shoulder portion 30, the diameter of the shoulder portion 30 is greater than the diameter of the bottle mouth portion 40, the base portion 10 is cylindrical, and the ratio of the height of the base portion 10 in the axial direction of the packaging bottle to the height of the packaging bottle is greater than or equal to 0.44.

[0025] Wherein, the axial direction of the packaging bottle is the axial direction of the base portion 10, and the axial direction is the same as the length direction of the packaging bottle. Figure 1 The dotted line passing through the packaging bottle can be understood as the axis of the packaging bottle, and the direction shown by the double-headed arrow on one side of the packaging bottle can be understood as the length direction of the packaging bottle.

[0026] It should be understood that in this application, the diameter of the transition portion 20 does not include the diameter at the connection between the transition portion 20 and the base portion 10, the diameter of the shoulder portion 30 does not include the diameter at the connection between the transition portion 20 and the shoulder portion 30, and the diameter of the bottle mouth portion 40 does not include the diameter at the connection between the shoulder portion 30 and the bottle mouth portion 40.

[0027] Wherein, the diameter of the base portion 10 being greater than the diameter of the transition portion 20 can be understood as: along the axial direction of the packaging bottle, the diameter at any position on the base portion 10 is greater than the maximum diameter among the multiple positions included in the transition portion 20.

[0028] Similarly, the diameter of the transition portion 20 being greater than the diameter of the shoulder portion 30 can be understood as: along the axial direction of the packaging bottle, the diameter at any position on the transition portion 20 is greater than the maximum diameter among the multiple positions included in the shoulder portion 30;

[0029] The diameter of the shoulder portion 30 being greater than the diameter of the bottle mouth portion 40 can be understood as: along the axial direction of the packaging bottle, the diameter at any position on the shoulder portion 30 is greater than the maximum diameter among the multiple positions included in the bottle mouth portion 40.

[0030] In this application, by setting the base 10 of the packaging bottle to be cylindrical and defining the ratio of the height of the base 10 to the height of the bottle body to be greater than or equal to 0.44, the contact area between the packaging bottle and the heat-shrinkable film during heat sealing is increased, thereby increasing the limiting effect of the heat-shrinkable film on the packaging bottle. This can avoid the problem of the top of the bottle tilting due to the wrapping force during the heat-shrinkable film packaging process of multiple packaging bottles. Therefore, it can support the secondary packaging process of heat-shrinkable film packaging to replace the secondary packaging process using cartons, significantly reducing the secondary packaging cost of the packaging bottle.

[0031] During the heat-sealing process, the outer wall of the base 10 of the target packaging bottle fits with the heat-shrinkable film, and / or, the outer wall of the base 10 of the target packaging bottle abuts against the outer wall of the base 10 of other packaging bottles. Herein, the target packaging bottle can be understood as any one of the multiple packaging bottles to be heat-sealed, and the other packaging bottles can be understood as any one of the multiple packaging bottles to be heat-sealed except the target packaging bottle.

[0032] In application, a product label is sleeved on the outer wall of the transition part 20. The product label is used to describe information such as the composition of the liquid filled in the packaging bottle, the manufacturer, and the shelf life. The product label is adhered to the outer wall of the transition part 20.

[0033] An external thread rib is provided on the outer wall of the bottle mouth part 40 to threadedly connect the bottle cap to the bottle mouth part 40 by cooperating with the internal thread rib provided on the inner wall of the bottle cap. When the bottle cap is threadedly connected to the bottle mouth part 40, the internal cavity of the packaging bottle is closed by the bottle cap.

[0034] In one embodiment, a rib groove 11 is formed on the outer wall of the base 10. The groove width of the rib groove 11 is greater than or equal to 5 mm and less than or equal to 12 mm;

[0035] and / or,

[0036] The groove depth of the rib groove 11 is greater than or equal to 1 mm and less than or equal to 4.5 mm.

[0037] Furthermore, the rib groove 11 spirally extends on the outer wall of the base 10 along the axial direction of the packaging bottle.

[0038] In this embodiment, by forming the spirally extending rib groove 11, without adding additional structures, the structural strength of the base 10 is improved, reducing the probability of deformation of the base 10 in high-temperature or low-temperature environments, and further enhancing the stability of the heat-shrink seal packaging formed based on the packaging bottle of this application.

[0039] Among them, the groove depth of the limiting rib groove 11 is greater than or equal to 1 mm to ensure that the effect of strengthening the structural strength of the base portion 10 by the rib groove 11 can be effectively applied. And the groove depth of the limiting rib groove 11 is less than or equal to 4.5 mm to avoid excessive requirements for the wall thickness of the base portion 10 due to the setting of the too-deep rib groove 11, so as to reduce the manufacturing cost of the packaging bottle;

[0040] Similarly, the groove width of the limiting rib groove 11 is greater than or equal to 5 mm to ensure that the effect of strengthening the structural strength of the base portion 10 by the rib groove 11 can be effectively applied. And the groove width of the limiting rib groove 11 is less than or equal to 12 mm to facilitate the setting of a larger number of rib grooves 11, so as to make full use of the limited space on the outer wall of the base portion 10.

[0041] Further, a plurality of the rib grooves 11 are formed on the outer wall of the base portion 10, and the plurality of the rib grooves 11 are arranged in an array around the axis of the packaging bottle. The ratio of the height of the rib groove in the axial direction of the packaging bottle to the height of the base portion in the axial direction of the packaging bottle is greater than or equal to 0.8.

[0042] Through the cooperation of the plurality of rib grooves 11 arranged in an array around the axis of the packaging bottle, the structural strength of the base portion 10 is synergistically strengthened, the anti-deformation ability of the base portion 10 is further increased, and the probability of deformation of the base portion 10 in a high-temperature environment or a low-temperature environment is reduced.

[0043] Among them, the ratio of the height of the rib groove in the axial direction of the packaging bottle to the height of the base portion in the axial direction of the packaging bottle is set to be greater than or equal to 0.8 to ensure that the enhancing effect of the rib groove on the structural strength of the base portion is fully exerted.

[0044] In some embodiments, the angle between the rib groove and the horizontal reference line when the rib groove is unfolded can be between 15° and 75°, which can further ensure that the enhancing effect of the rib groove on the structural strength of the base portion is fully exerted.

[0045] Exemplarily, the number of the rib grooves 11 formed on the outer wall of the base portion 10 can be 4 - 6.

[0046] In one embodiment, along the extending direction of the rib groove 11, the groove width of the rib groove 11 gradually decreases from the middle of the rib groove 11 to the edge portion of the groove opening of the rib groove 11; and along the extending direction of the rib groove 11, the groove depth of the rib groove 11 gradually decreases from the middle of the rib groove 11 to the edge portion of the groove opening of the rib groove 11.

[0047] In this embodiment, based on the above settings, the setting difficulty of the rib groove 11 can be reduced, and at the same time, the edge of the two ends of the rib groove 11 tends to be smooth, providing a better gripping experience of the packaging bottle for users.

[0048] In one embodiment, the diameter of the transition portion 20 gradually decreases in a direction away from the base portion 10.

[0049] In this embodiment, based on the above settings, the transition portion 20 is tapered to avoid contact between different product labels attached to different packaging bottles within the heat shrink wrap, thereby avoiding frictional damage caused by contact between different product labels and keeping the product labels intact.

[0050] In one embodiment, as Figure 2 shown, the diameter of the shoulder portion 30 gradually decreases in a direction away from the transition portion 20.

[0051] Further, a plurality of load-bearing surfaces 31 are provided on the outer wall of the shoulder portion 30. The plurality of load-bearing surfaces 31 are arranged around the axis of the packaging bottle. Each load-bearing surface 31 includes a first side 311 connected to the bottle mouth portion 40, a second side 312 connected to the transition portion 20, and two side edges 313 located between the first side 311 and the second side 312. Adjacent two load-bearing surfaces 31 share the same side edge 313.

[0052] In this embodiment, by the mutual cooperation of the plurality of load-bearing surfaces 31 provided on the outer wall of the shoulder portion 30, the vertical load-bearing performance of the packaging bottle in the axial direction is improved to cooperate with the settings such as the rib grooves 11 of the base portion 10, further enhancing the structural strength of the packaging bottle and reducing the probability of deformation of the packaging bottle in high-temperature or low-temperature environments.

[0053] Specifically, the second side 312 is arc-shaped, and the distance from the end point of the second side 312 to the bottle mouth portion 40 is less than or equal to the distance from any point on the second side 312 to the bottle mouth portion 40.

[0054] In this embodiment, based on the setting of the arc-shaped edge, the edge at the connection between the shoulder portion 30 and the transition portion 20 tends to be blunt, reducing the discomfort when the user holds the connection between the shoulder portion 30 and the transition portion 20 and providing a better holding experience for the user.

[0055] Among them, compared with the scheme of setting the distance from the end point of the second side 312 to the bottle mouth portion 40 to be greater than or equal to the distance from any point on the second side 312 to the bottle mouth portion 40, setting the distance from the end point of the second side 312 to the bottle mouth portion 40 to be less than or equal to the distance from any point on the second side 312 to the bottle mouth portion 40 can make the connection between the shoulder portion 30 and the transition portion 20 closer, so that the transition portion 20 can better cooperate with the shoulder portion 30 for load-bearing, which can further improve the vertical load-bearing performance of the shoulder portion 30.

[0056] In one embodiment, the load-bearing surface 31 is a concave surface.

[0057] In this embodiment, the concave surface is provided to facilitate the user's grip on the shoulder 30.

[0058] In some embodiments, the angle between the load-bearing surface and the horizontal direction can be set to be greater than or equal to 35 degrees to ensure that the vertical load-bearing performance of the load-bearing surface is fully exerted.
