Description

Technical Field

[0001] This application relates to the field of packaging container technology, and in particular to a squeeze-type packaging container with a grip-assisted emptying structure. Background Technology

[0002] Existing squeeze tube packaging (such as toothpaste tubes, facial cleanser tubes, industrial glue tubes, and food condiment tubes such as ketchup, oyster sauce, and salad dressing) has two major pain points in actual use: First, poor grip and anti-slip performance—the outer wall of the tube is mostly made of smooth and flexible material. When the user's hands are wet, oily, or wearing work gloves, the friction of the tube surface is greatly reduced, making it easy to slip and drop when gripping and squeezing, and difficult to apply stable squeezing force; Second, serious waste of material residue at the tail end—when the material inside the tube is almost exhausted, the tail end of the tube lacks rigid support and force fulcrum. It is impossible to completely squeeze out the remaining material at the bottom by simply pinching with fingers. This is especially true for high-viscosity pastes, where the amount of residue at the tail end is even greater, resulting in material waste. Summary of the Invention

[0003] The purpose of this application is to provide a squeeze-type packaging container with a grip-assisted emptying structure to solve the technical problems of slippage when gripping existing hoses and difficulty in squeezing out residue at the tail end.

[0004] To achieve the above objectives, this application adopts the following technical solution: A squeeze-type packaging container with a grip-assisted emptying structure includes a flexible tube body, and a rigid auxiliary wing is fixed to the area near the tail end of the flexible tube body; the rigid auxiliary wing is a sheet-like structure, and at least one end of the rigid auxiliary wing extends along a direction perpendicular to the axis of the flexible tube body and protrudes from the side wall contour of the flexible tube body, the protruding part forming a gripping section, and the part of the rigid auxiliary wing connected to the flexible tube body is a connecting section.

[0005] In the above technical solution, a rigid auxiliary wing is fixed in the area near the tail end of the flexible tube. At least one end of the wing extends perpendicularly to the tube axis and extends outward to form a gripping section. This rigid auxiliary wing has dual functions of gripping assistance and emptying assistance: when gripping, the user's fingers pinch the gripping section, and the hard, flat surface provides stable normal support and static friction, making it less prone to slipping even if the hands are wet, oily, or wearing gloves, effectively preventing the tube from slipping and falling and being damaged; the flat structure of the gripping section forms a circumferential limit when the fingers pinch, preventing the tube from rotating during use and improving the stability and control precision of the extrusion operation; at the same time, the gripping section forms a raised limiting surface in the axial direction of the tube, and when the fingers press against the gripping section during extrusion, it can prevent the tube from sliding forward and slipping out of the hand. During emptying, the rigid auxiliary wing serves as the core pivot point for folding, causing the tail of the tube to fold around the wing plate. The wing plate, acting as a rigid frame, guides the tube to undergo directional and flat folding deformation, thoroughly squeezing out any remaining material at the bottom. At this time, the rigid auxiliary wing acts as a lever arm, allowing the user to use a rigid surface such as a table as a fulcrum to effortlessly squeeze out the contents. Furthermore, since the grip section protrudes from the side wall of the tube, its protruding structure itself can serve as a mounting point or insertion guide, enabling suspended storage and slotted insertion storage. Simultaneously, the protrusion forms a physical barrier when the tube is placed on a table, effectively preventing the tube from rolling freely on the table and avoiding damage from falling.

[0006] Preferably, the rigid auxiliary wing is made of a material with a harder hardness than the flexible tube. Because the rigid auxiliary wing is harder than the flexible tube, the connecting section acts as a rigid support point during the extrusion process, guiding the tail of the flexible tube to fold smoothly around the rigid auxiliary wing, ensuring a neat and orderly folding process and more thorough extrusion.

[0007] Preferably, the rigid auxiliary wing is a rectangular sheet structure. The rectangular sheet structure has a regular shape and no redundant shape, which makes the mold structure simple and the demolding smooth during injection molding, which helps to reduce the mold opening cost and mass production difficulty; at the same time, its flat surface can provide a stable and uniform force surface, making it easy for users to knead and apply force.

[0008] Preferably, the tail end of the flexible tube is a flat end cap structure, and the rigid auxiliary wing is fixedly installed at the flat end cap structure. The flat end cap is the part of the tube that is easiest to fold. The rigid auxiliary wing is installed here, and when emptying, the folding starting point coincides with the wing plate fulcrum, ensuring that the tail of the tube is completely flattened without leaving any dead corners.

[0009] Preferably, the two ends of the rigid auxiliary wing extend to opposite sides in a direction perpendicular to the axis of the flexible tube, and both ends protrude beyond the sidewall contour of the flexible tube. The symmetrical protrusion on both sides allows the user to pinch the two grip sections with both hands respectively, making the force more symmetrical and balanced when folding with a flat surface such as a table, preventing the tube from tilting and making emptying easier.

[0010] Preferably, the grip section has a notch, which, together with the edge of the grip section, forms a hook for suspension; alternatively, the grip section has a hanging hole. The hook allows the container to be directly attached to a hook, crossbar, or other carrier, enabling quick suspension without additional accessories; the hanging hole allows a hanging rope or S-hook to pass through, providing a more secure fixation and preventing it from easily coming loose due to shaking, making it suitable for use in mobile environments.

[0011] Preferably, the surface of the grip section is provided with an anti-slip texture, which is at least one of strip-shaped protrusions, a mesh pattern, or pits. The anti-slip texture increases the surface roughness of the grip section, and when fingers pinch, they are embedded in the texture, greatly increasing the friction and further improving the anti-slip effect.

[0012] Preferably, the length of the gripping section is greater than the length of the connecting section along the axial direction of the flexible tube. The larger axial dimension of the gripping section provides a larger finger pinching area for a more comfortable grip; simultaneously, the longer lever arm during lever emptying results in a greater emptying torque with the same hand force, making emptying easier.

[0013] Preferably, the gripping section includes a transition section near the connecting section and a force-applying section away from the connecting section; along the axis of the flexible tube, the length of the force-applying section is greater than the length of the connecting section, and the length of the transition section is less than or equal to the length of the connecting section. The transition section is closer to the tube and shorter in length, making it easier for fingers to avoid the corner between the tube and the wing plate when pinching, thus reducing interference; the force-applying section is farther from the tube and longer in length, providing sufficient force-applying area and lever arm length, realizing the functional zoning of "avoidance + force application" and optimizing the force transmission path.

[0014] Preferably, the rigid auxiliary wing and the flexible tube are integrally formed; alternatively, the rigid auxiliary wing is fixed to the flexible tube by adhesive bonding. Integral molding is suitable for newly manufactured tubes, offering the highest connection strength, no risk of detachment, and suitability for mass production; adhesive bonding is suitable for modifying existing tubes, offering high flexibility and adaptability to different tube materials.

[0019] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] Example 1: like Figures 1 to 6 As shown, a squeeze-type packaging container with a grip-assisted emptying structure includes a flexible tube 1, and a rigid auxiliary wing 2 is fixed to the area near the tail end of the flexible tube 1. The rigid auxiliary wing 2 has a sheet-like structure, and at least one end of the rigid auxiliary wing 2 extends along a direction perpendicular to the axis of the flexible tube 1 and protrudes from the side wall contour of the flexible tube 1. The protruding part forms a gripping section 22, and the part where the rigid auxiliary wing 2 connects to the flexible tube 1 is a connecting section 21.

[0021] For ease of understanding, some key terms in this embodiment are explained below.

[0022] Flexible tube 1 refers to the main body of a flexible packaging container used to contain pastes and fluids. One end of the container is equipped with a discharge port and a screw cap, while the other end is a sealing structure. The tube wall can be made of single or multiple layers of flexible composite materials.

[0023] The rigid auxiliary wing 2 is a rigid sheet-like component fixedly installed near the tail end of the flexible tube 1. Its material hardness is greater than that of the flexible tube 1, and it has an overall sheet-like structure. The rigid auxiliary wing 2 is divided into two parts: a connecting section 21 and a gripping section 22. The connecting section 21 is fixedly connected to the flexible tube 1, and the gripping section 22 protrudes outward from the side wall of the tube.

[0024] The connecting section 21 refers to the part of the rigid auxiliary wing 2 that is directly connected to and fixed to the flexible tube 1. The shape of the mating surface of the connecting section 21 and the flexible tube 1 is adapted to the outer wall of the tube to ensure a firm connection.

[0025] The grip section 22 refers to the portion of the rigid auxiliary wing 2 that protrudes outward from the sidewall of the flexible tube 1. The grip section 22 is the area where the user's fingers pinch; its hard, flat surface provides a stable gripping interface, while simultaneously forming a raised limiting surface along the tube's axial direction. Furthermore, because the grip section 22 is a sheet-like structure protruding from the tube's sidewall, its flat shape and protruding features allow it to be hung on hooks, ropes, clotheslines, or other carriers for suspended storage. It can also be directly inserted into narrow spaces such as gaps between shelf panels or side pockets of backpacks for secure storage, without the need for additional accessories.

[0026] The extrusion packaging container of this application features a rigid auxiliary wing 2 fixed to the area near the tail end of a flexible tube 1. The gripping section 22 of the wing extends perpendicularly to the tube axis and extends outward from the tube. This rigid auxiliary wing 2 has dual functions: gripping assistance and emptying assistance. When gripping, the user pinches the gripping section 22 with their fingers. The hard, flat surface provides stable normal support and static friction. Even if the hands are wet, oily, or wearing gloves, the surface of the wing can still provide stable static friction between the fingers, making it less prone to slipping. At the same time, the flat structure of the gripping section 22 forms a circumferential limit when the fingers pinch, preventing the tube from rotating during use and improving the stability and control precision of the extrusion operation. The gripping section 22 forms a raised limiting surface in the axial direction of the tube. When extruding material forward, the fingers press against the gripping section 22, preventing it from moving towards the discharge port, thereby preventing the entire flexible tube 1 from slipping forward and slipping out of the hand under the extrusion force, effectively preventing the tube from slipping and falling and being damaged. During emptying, the rigid auxiliary wing 2 serves as the core pivot point for folding, causing the tail of the flexible tube 1 to fold around the wing plate. The wing plate, acting as a rigid frame, guides the tube to undergo directional and flat folding deformation, completely squeezing out any remaining material at the bottom. At this time, the rigid auxiliary wing 2 acts as a lever arm, allowing the user to use a rigid surface such as a table as a fulcrum to effortlessly squeeze out the contents. Furthermore, since the grip section 22 protrudes from the side wall of the tube, its protruding structure itself can serve as a mounting point or insertion guide—it can be directly hung on hooks, ropes, or other carriers, or inserted into gaps in shelves, backpack side pockets, or other openings, without relying on bottle caps for upright positioning or additional fasteners, making it suitable for various scenarios such as bathrooms, workshops, and outdoors. At the same time, the protrusion forms a physical barrier when the tube is placed on a table, effectively preventing the tube from rolling around on the table and avoiding damage from falling.

[0027] In this embodiment, the rigid auxiliary wing 2 has a higher material hardness than the flexible tube 1. During the extrusion and venting process, the connecting section 21 acts as a rigid support, guiding the tail of the flexible tube 1 to fold smoothly around the rigid auxiliary wing 2.

[0028] In this embodiment, the rigid auxiliary wing 2 is a rectangular sheet structure.

[0029] It is understood that the protruding direction of the rigid auxiliary wing 2 is not limited to protruding on one side, but can also protrude from both sides of the tube sidewall to form a double-sided gripping structure; the end profile of the gripping section 22 is not limited to a rectangle, but can also be arc-shaped, rounded, or other applicable shapes, all of which fall within the protection scope of this application.

[0030] Example 2: Based on Example 1, the tail end of the flexible tube 1 is a flat end cap structure, and the rigid auxiliary wing 2 is fixedly installed at the flat end cap structure.

[0031] Flat sealing is the conventional sealing method for flexible tube packaging. The tube wall thickness is the smallest and the structural rigidity is the lowest at the sealing point, making it the area where the tube body preferentially folds and deforms under pressure. The rigid auxiliary wing 2 is set at the flat sealing structure. When performing the folding and emptying operation, the folding deformation of the flexible tube body 1 starts from the sealing point. The folding starting point is consistent with the position of the wing plate, guiding the tube body to produce a directional and flat fold along the plane of the wing plate, avoiding the tube body from twisting, misaligning or irregular deformation, making the folding more regular and the emptying more thorough.

[0032] It is understood that the tail end of the flexible tube 1 can also be a folded tail or other tail form, and the rigid auxiliary wing 2 can be set near the tail. This application is not limited to a flat tail structure.

[0033] Example 3: Based on Example 1, the two ends of the rigid auxiliary wing 2 extend to opposite sides in a direction perpendicular to the axis of the flexible tube 1, and both ends protrude beyond the side wall contour of the flexible tube 1.

[0034] The symmetrically extended structure on both sides allows the user to grasp the two grip sections 22 with both hands, folding the tube with the aid of a flat surface such as a table, resulting in more symmetrical and balanced force distribution. When the lever is de-energized, the tube folds along the center line of the wing plate, ensuring even force distribution and preventing tilting. Compared to a single-sided extension, the dual-sided structure is more stable and has wider applicability.

[0035] It is understandable that the rigid auxiliary wing 2 can also protrude from the tube sidewall on only one side, so as to save materials while still achieving the functions of gripping and emptying. This application is not limited to a double-sided protruding structure.

[0036] Example 4: Based on Example 1, such as Figure 3 As shown, the gripping section 22 has a notch 23, and the notch 23 and the edge of the gripping section 22 enclose a hook portion 24 for suspension and engagement; or, as Figure 4 As shown, the grip section 22 has a suspension hole 25.

[0037] The hook portion 24 can be directly attached to a carrier such as a hook, rope, or crossbar. The hanging hole 25 allows the hook, rope, or S-hook to pass through for suspension. Compared to the hook portion 24 formed by the notch, the hanging hole 25 provides a more secure fixation and is less likely to come off due to shaking, making it suitable for use in mobile environments.

[0038] It is understandable that the shape of the hook portion 24 is not limited to the structure formed by the notch, but can also be a hook structure formed by bending the end of the gripping section 22 inward.

[0039] Example 5: Based on any one of embodiments 1 to 4, the surface of the grip section 22 is provided with an anti-slip texture, which is at least one of strip-shaped protrusions, a grid pattern, or pits.

[0040] The anti-slip texture increases surface roughness, embedding itself into the skin of the fingertips or the surface of the glove when the fingers are pinched, significantly increasing friction and further preventing fingers from slipping on the wing plate surface. Strip-shaped protrusions can extend along the width or length of the grip section 22; the grid pattern consists of crisscrossing protrusions or grooves; and the pits are discretely distributed recessed structures. The three textures can be used individually or in combination.

[0041] It is understandable that anti-slip textures can also be other texture forms besides the three mentioned above, as long as they can increase surface roughness.

[0042] Example 6: Based on any one of Examples 1 to 4, such as Figure 6 As shown, along the axial direction of the flexible tube 1, the length of the holding section 22 is greater than the length of the connecting section 21.

[0043] The axial dimension (width in the direction of the tube axis) of the grip section 22 is greater than that of the connecting section 21, providing a larger finger pinching area for a more comfortable and stable grip. At the same time, the lever arm is longer when emptying the lever, resulting in a greater emptying torque with the same hand force, making emptying easier and more thorough.

[0044] It is understood that the specific length ratio of the holding section 22 to the connecting section 21 can be adjusted according to the pipe specifications and usage scenarios, and this application is not limited to a certain fixed ratio.

[0045] Example 7: Based on any one of Examples 1 to 4, such as Figure 5 As shown, the gripping section 22 includes a transition section 221 close to the connecting section 21 and a force-applying section 222 away from the connecting section 21; along the axial direction of the flexible tube 1, the length of the force-applying section 222 is greater than the length of the connecting section 21, and the length of the transition section 221 is less than or equal to the length of the connecting section 21.

[0046] The transition section 221 is closer to the tube body and shorter in length, making it easier for fingers to avoid the corner between the tube body and the wing plate when pinching, reducing interference. The force application section 222 is farther away from the tube body and longer in length, providing sufficient force application area and lever arm length to maximize lever efficiency. Through functional zoning, the division of labor between "avoidance + force application" is achieved within a limited space, optimizing the force transmission path.

[0047] It is understandable that the division of the transition section 221 and the force application section 222 is not limited to simple segmentation along the axial direction, but can also be a gradual transition structure.

[0048] Example 8: Based on any one of embodiments 1 to 4, the rigid auxiliary wing 2 and the flexible tube 1 are integrally formed; or, the rigid auxiliary wing 2 is fixed to the flexible tube 1 by adhesive bonding.

[0049] One-piece molding is suitable for newly manufactured tubes. The rigid auxiliary wing 2 is integrally molded with the flexible tube 1 as an insert in the injection or blow molding process, resulting in the highest connection strength, no risk of detachment, suitability for mass production, and lowest cost. The adhesive bonding method is suitable for the modification of existing tubes or special material combinations. The prefabricated rigid auxiliary wing 2 is fixed to the surface of the tube using medical-grade or industrial-grade adhesives, offering high flexibility.

[0050] It is understandable that the rigid auxiliary wing 2 and the flexible tube 1 can also be fixed by means of hot melt welding, ultrasonic welding, fastener connection, etc.

[0051] It is understood that this application is not limited to the specific structure described above, and any non-substantial modifications made based on the technical solution of this application shall fall within the scope of protection of this application.

[0052] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
