Description

[Technical Field]

[0001] The present invention relates to the technical field of squeeze bottle related equipment, and more particularly to a squeeze bottle and an electric squeeze device. [Background technology]

[0002] A conventional electric squeezing container consists of two parts: a tube structure and a pressure cover structure, which are connected to each other. A containing chamber is provided in the tube structure, and the containing chamber contains the material. A piston and screw assembly are installed in the containing chamber, and components such as a geared motor, battery, and control circuit board are installed in the pressure cover structure. The geared motor supplies power to the screw via planetary gears, and the rotation of the screw pushes the piston in a linear motion, thereby achieving synchronous squeezing of one or more materials from the tube structure.

[0003] A planetary gear transmission structure that drives the screw assembly and piston is attached to the connection point between the tail of the tube structure and the pressing cover structure. Therefore, when the screw rotates and pushes the piston in a linear motion, material is likely to flow through the piston and screw into the planetary gear transmission structure, the battery in the pressing cover structure, and the control circuit board. This will result in contamination of various components in the pressing cover structure, making the electric squeezing bottle more likely to break down and reducing the work efficiency of the electric squeezing bottle. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention aims to provide a squeeze bottle and an electric squeeze device, in which a cover plate is connected to the tail of the squeeze bottle, and the cover plate positions and supports the drive-driven squeezing mechanism and seals the container body to seal the material inside, thereby eliminating the leaking problem caused by the material leaking out through the drive-driven squeezing mechanism, reducing the risk of the squeeze bottle breaking down, and improving the work efficiency of the squeeze bottle squeezing material. [Means for solving the problem]

[0005] In a first aspect, the present invention provides a squeeze container, comprising a container body, a cover plate, and a transmission squeezing structure, the container body having a chamber for containing a material, the container body having an outlet communicating with the chamber, the cover plate being detachably connected to a tail end of the container body by a connecting structure and configured to seal the container body, and the transmission squeezing structure being installed within the container body and movably connected to the cover plate and configured to squeeze the material in the chamber through the outlet.

[0006] In the above technical solution, a cover plate is connected to the tail of the squeezing container to seal the material inside the chamber. A power squeezing structure for squeezing material is installed inside the container body, and the cover plate is movably connected to the power squeezing structure, so that the cover plate plays a role in positioning and supporting the power squeezing structure when the power squeezing structure squeezes material to the outlet, allowing the power squeezing structure to squeeze material from the outlet more automatically, stably, and efficiently. The sealing effect of the cover plate alleviates the problem of material leakage from the chamber when the power squeezing structure squeezes material, reduces the risk of the squeezing container breaking down, and improves the work efficiency of the squeezing container squeezing material.

[0007] In one embodiment, the container body further includes a partition plate, which is installed in the chamber and divides the chamber into several sub-chambers along the extension direction of the container body, and the sub-chambers communicate with the outlet.

[0008] In the above technical solution, the chamber is divided into multiple sub-chambers by installing partition plates, and each sub-chamber contains a material of a different composition. The transmission squeezing structure can drive the synchronous squeezing of the materials of different compositions in the sub-chambers, so that the materials can be mixed when used.

[0009] In one embodiment, one end of the partition plate extends to the outlet and the other end abuts the cover plate.

[0010] In the above technical solution, the contact between the cover plate and the partition plate serves as a positioning mechanism during installation. The interaction forces in both the up and down directions created by the partition plate installation and connection structure provide sufficient support for the power-driven squeezing structure, further improving the stability of the connection between the partition plate and the container body, allowing the power-driven squeezing structure to more automatically, stably, and efficiently squeeze out material from the outlet.

[0011] In one embodiment, the transmission squeezing structure includes a transmission member and a piston, one end of the transmission member is movably connected to the cover plate, the transmission member is installed in the chamber along the extension direction of the container body, and the piston is movably connected to the transmission member, and the transmission member drives the piston to move forward or backward along the extension direction of the axis of the transmission member to realize material squeezing.

[0015] In one embodiment, a position limiting protrusion rib is provided within the shaft mounting portion, and a position limiting groove that fits into the position limiting protrusion rib is provided on a portion of the transmission member that is located within the shaft mounting portion.

[0016] In the above technical proposal, the engagement between the position limiting protrusion rib and the position limiting groove ensures that the transmission member is relatively firmly connected within the shaft mounting portion when transmitting power to the piston, thereby reducing the risk of the transmission member coming loose.

[0017] In one embodiment, the shaft mounting portion is provided with a groove along the extension direction of the axis of the transmission member.

[0018] In the above technical proposal, by providing a groove, the shaft mounting portion has a certain degree of elasticity, which contributes to the mounting of the transmission member, and the transmission member is movably connected to the cover plate by the engagement between the position limiting protrusion rib and the position limiting groove.

[0021] In one embodiment, the cross section of the male connection head or the female connection head is circular or polygonal.

[0022] In the above technical proposal, the male connection head or the female connection head has a polygonal cross-section, which prevents the transmission member from rotating freely on the cover plate and contributes to the quick alignment and connection between the transmission member and the drive structure.

[0024] In the above technical solution, the transmission member and the piston are threadedly connected, and when the transmission member is rotated by the drive structure, the rotation of the transmission member drives the piston to move forward or backward in the axial extension direction of the transmission member, thereby squeezing or sucking material into or out of the chamber.

[0025] In one embodiment, the piston includes a piston body and a skirt structure, and the skirt structure is provided on the piston body and is inclined toward the inner wall of the chamber.

[0026] In the above technical proposal, by providing a skirt structure, it is possible to obtain a good seal between the piston and the inner wall of the chamber, and also to ensure the freedom of movement of the piston.

[0030] In the above technical solution, the skirt structure is inclined outward at a certain angle with the piston, and its outermost dimension is larger than the inner dimension of the chamber of the container body, thereby providing a good seal between the piston and the inner wall of the chamber, and when the transmission member drives the piston forward to squeeze out the toothpaste, the piston presses the skirt structure under pressure, which makes the skirt structure more tightly adhere to the inner wall of the chamber under the action of pressure, and the piston plays a role in sealing the chamber.

[0031] In one embodiment, the skirt structure includes a first skirt structure and a second skirt structure, the first skirt structure being provided at an end of the piston body remote from the cover plate, and the second skirt structure being provided at an end of the piston body adjacent to the cover plate.

When the piston retracts, the second skirt structure also fits tightly to the inner wall of the chamber, thereby sealing the chamber and improving the stability of the piston.

[0033] In one embodiment, the skirt structure further includes a third skirt structure, the third skirt structure being provided on the piston body and positioned between the first skirt structure and the second skirt structure.

[0039] In one embodiment, the connecting structure further includes a positioning rib, and the positioning rib is provided on an end of the engaging member that engages with the engaging opening.

[0040] In the above technical solution, the provision of a positioning rib can improve the stability of the connection between the engaging member and the engaging port.

[0041] In one embodiment, the engaging member is formed as a curved arc-shaped structure that is bent in the extension direction of the container body, and the positioning rib is provided at the end of the engaging member that is spaced from the arc-shaped structure and engages with the engaging opening.

[0042] In the above technical solution, the engaging member has an arc-shaped structure with a certain degree of elasticity, and when the user presses the positioning rib, the engaging member can be quickly released from the engaging opening, making removal easy.

[0045] In one embodiment, the connection structure includes a first connection portion and a second connection portion, the first connection portion being provided on the container body and the second connection portion being provided on the cover plate, and the first connection portion and the second connection portion being screw-connected.

[0051] In one embodiment, the first connection portion has a female thread structure and the second connection portion has a male thread structure, or the first connection portion has a male thread structure and the second connection portion has a female thread structure.

[0052] In the above technical solution, the first connecting part and the second connecting part are screw-connected, which makes the connection method between the container body and the cover plate simpler and easier for users to operate.

[0053] In one embodiment, the cross-sectional dimension of the container body tapers from the tail end of the container body to the outlet end of the container body.

[0054] In the above technical proposal, the cross-sectional dimension of the container body from the tail to the outlet is adjusted to be small, thereby controlling the amount of toothpaste used per serving, preventing waste and allowing the user to control the amount used. This design takes into account the complex ingredients of toothpaste and the user's usage habits, allowing the user to better control the amount used per serving and preventing waste caused by excessive use. This design also takes into account the quality of the toothpaste, and by reducing the amount used per serving, it can alleviate quality issues of the toothpaste caused by contact with air and ensure the freshness and effectiveness of the toothpaste.

The stand, on which the conductive components are installed, is then connected to the squeeze container for assembly. After the stand and squeeze container are assembled, the drive structure is connected to the transmission squeeze structure in the squeeze container. When the user turns on the switch, the circuit between the squeeze container and the stand is established. The control unit sends a control command to the drive structure based on the signal from the user turning on the switch. The drive structure receives the command and drives the transmission squeeze structure to operate, causing the rotation of the transmission member to drive the piston forward, thereby realizing automatic, synchronized squeezing of materials with different compositions.

[0059] In one embodiment, the container body is provided with a groove, a wire is disposed in the groove, and the switch is electrically connected to the insert member through the wire.

[0071] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0072] Since like reference numerals refer to like objects in the drawings, a definition in one drawing does not require further definition or interpretation in other drawings. Furthermore, in the description of the present invention, terms such as "first," "second," etc. are used merely for the purpose of distinction and description, and do not express or imply any relative importance.

[0073] 1, 2, 3, and 4 are schematic diagrams of a squeeze container 10 according to the present invention. The squeeze container 10 includes a container body 100, a cover plate 200, a connecting structure 300, and a transmission squeezing structure 400. The container body 100 is provided with a chamber 110 for accommodating a material, and the container body 100 is provided with an outlet 120 communicating with the chamber 110. The cover plate 200 is detachably connected to the tail end of the container body 100 by the connecting structure 300 and configured to seal the container body 100. The transmission squeezing structure 400 is installed within the container body 100 and movably connected to the cover plate 200, and configured to squeeze the material in the chamber 110 through the outlet 120.

[0074] In this embodiment, material is stored in chamber 110 within squeeze container 10, and a cover plate 200 is connected to the tail of squeeze container 10 to seal the material within chamber 110. A drive-driven squeezing structure 400 for squeezing material is installed within container body 100, and the cover plate 200 is movably connected to drive-driven squeezing structure 400. As drive-driven squeezing structure 400 squeezes material into outlet 120, cover plate 200 serves to position and support drive-driven squeezing structure 400, allowing drive-driven squeezing structure 400 to more automatically, stably, and efficiently squeeze material out of outlet 120. The sealing effect of cover plate 200 alleviates the problem of material leakage from chamber 110 when drive-driven squeezing structure 400 squeezes material, reduces the risk of malfunction of squeeze container 10, and improves the work efficiency of squeeze container 10 in squeezing material.

[0075] To facilitate filling the chamber 110 with material, the tail of the container body 100 and the cover plate 200 are detachably connected by the connecting structure 300. During an operation, material is filled into the chamber 110 from the tail of the container body 100 until the material level is a predetermined distance from the tail of the container body 100. This prevents the material from overflowing due to the pressure of the driving squeezing structure 400, resulting in waste and contamination, when the driving squeezing structure 400 and cover plate 200 are attached when the chamber 110 is full of material. The driving squeezing structure 400 is then attached to the cover plate 200, and the driving squeezing structure 400 is then pushed into the chamber 110 filled with material. Finally, the cover plate 200 is pushed into the container body 100 and assembled with the tail of the container body 100 by the connecting structure 300, thereby positioning and fixing the cover plate 200.

[0076] In some embodiments, after the material in the container body 100 is used up, the cover plate 200 is removed from the container body 100 using the connecting structure 300, and the chamber 110 of the container body 100 is filled with the same type or composition of material. In such a case, when production costs are a primary consideration, the squeeze container 10 can be reused repeatedly. When environmental protection, hygiene, etc. are considered, the squeeze container 10 can be used as a disposable consumable item, and the squeeze container 10 will not be reused after the material in the container body 100 has run out.

[0077] In some embodiments, the shape of the container body 100 is a tubular structure with a regular shape, such as a cylindrical shape, or an irregular shape, such as an elliptical cylinder. Correspondingly, the cover plate 200 conforms to the shape of the container body 100 to achieve a seal therewith.

[0078] In some embodiments, the material of the container body 100 is polypropylene (PP), polyethylene (PE), polystyrene (PS), polycarbonate (PC), polyethylene terephthalate (PETG), polylactic acid (PLA), acrylonitrile-butadiene-styrene plastic (ABS), thermoplastic polyurethane (TPU), etc. The material of the container body 100 can be selected according to actual needs.

[0079] In some embodiments, the squeeze bottle 10 can be used in applications such as oral care, beauty and personal care, medicine, and industrial construction.

[0080] For example, in an oral care application scenario, the material contained in the chamber 110 of the container body 100 of the squeeze container 10 may be toothpaste, toothpaste powder, oral care liquid, etc. The toothpaste, toothpaste powder, and oral care liquid are automatically squeezed out by the powered squeezing mechanism 400, making oral care easier for the user.

[0081] In beauty and personal care applications, the materials contained in the chamber 110 of the container body 100 may be lotion, essence, emulsion, face cream, cleanser, paste mask, etc. The power-driven squeezing mechanism 400 automatically squeezes out the lotion, essence, emulsion, face cream, cleanser, and paste mask, making skin care easier for the user.

[0082] In medical applications, the materials stored in the chamber 110 of the container body 100 are disinfectants (e.g., alcohol, oxyful, etc.), liquid medicines, paste-like medicines, medicinal powders, etc. The power-driven squeezing structure 400 automatically squeezes out the disinfectants, liquid medicines, paste-like medicines, and medicinal powders, simplifying medical care for the user.

[0083] In industrial construction applications, the materials stored in the chamber 110 of the container body 100 are cement, lime paste, lime powder, etc. The power-driven squeezing mechanism 400 automatically squeezes out the cement, lime paste, lime powder, etc., making the work easier for workers.

[0084] For the sake of convenience, the squeeze bottle 10 of the present invention will be described below as an example of its use in oral care, with the material being toothpaste.

[0085] In some embodiments, the cross-sectional dimension of the container body 100 gradually decreases from the tail end of the container body 100 to the end of the outlet 120 of the container body 100. The gradually decreasing cross-sectional dimension of the container body 100 from the tail end to the end of the outlet 120 reduces the volume of toothpaste squeezed out with each squeeze. By gradually decreasing the cross-sectional dimension at the outlet 120, the amount of toothpaste used per squeeze can be controlled, preventing waste and allowing the user to control the amount used. This design takes into account the complex ingredients of toothpaste and the user's usage habits, allowing the user to better control the amount used per squeeze and preventing waste due to excessive use. This design also takes into account toothpaste quality issues. By reducing the amount used per squeeze, quality issues caused by contact with air can be reduced and the freshness and effectiveness of the toothpaste can be ensured.

[0086] In the first embodiment shown in Fig. 3, one chamber 110 is provided in the container body 100, and one power-driven squeezing mechanism 400 is correspondingly provided in the chamber 110. As a result, the squeezing container 10 according to the embodiment shown in Fig. 3 can automatically squeeze out a single-component material, i.e., can automatically squeeze out a single-component toothpaste.

[0087] In some other embodiments, as shown in Figures 4 and 5, the container body 100 further includes a partition plate 130, which is installed within the chamber 110 and divides the chamber 110 into several sub-chambers 111 along the extension direction of the container body 100, and the sub-chambers 111 are connected to the outlet 120.

[0088] In this embodiment, the partition plate 130 is installed within the chamber 110 and connected to the container body 100 to divide the chamber 110 into several sub-chambers 111 along the elongation direction of the container body 100. For example, as shown in FIG. 5 , one partition plate 130 is installed, dividing the interior space of the chamber 110 into two sections along the elongation direction of the container body 100, forming two sub-chambers 111 with the same volume. The two sub-chambers 111 may be filled with toothpaste pastes of different ingredients or toothpaste pastes of the same ingredients. Each sub-chamber 111 communicates with the outlet 120. The drive-driven squeezing structure 400 can synchronously drive the toothpastes in the two sub-chambers 111, thereby achieving simultaneous squeezing of two toothpastes with different ingredients, which can then be mixed when used.

[0089] In some other embodiments, as shown in FIG. 6 , three partition plates 130 are provided, and the three partition plates 130 may be integrally molded or connected by adhesive. The three partition plates 130 divide the interior space of the chamber 110 into three sections along the elongation direction of the container body 100, forming three sub-chambers 111 with the same volume. The three sub-chambers 111 may be filled with toothpastes of different ingredients or the same ingredients. All three sub-chambers 111 communicate with the outlet 120. An independent driving mechanism 400 is provided in each sub-chamber 111, and each driving mechanism 400 independently realizes automatic squeezing of the material in the corresponding sub-chamber 111. The driving mechanism 400 in each sub-chamber 111 is driven by an independent driving mechanism. Therefore, according to the usage needs of toothpastes with different ingredients, different numbers of partition plates 130 can be installed in the squeeze bottle 10 to divide the chamber 110 into different numbers of sub-chambers 111, for example, into four or more sub-chambers 111.

[0090] As can be seen from the structure of the squeeze container according to the embodiment shown in FIGS. 3, 4 and 6, the container body 100 is installed as a single tube structure, that is, one container body 100 is installed.

[0091] In another embodiment, a plurality of container bodies 100 may be provided, and the container bodies 100 may be connected to each other to form a squeeze container 10 for squeezing different materials.

[0092] In this embodiment, in one embodiment, each container body 100 is provided with one chamber 110, and each chamber is provided with one power-driven squeezing structure 400, which is movably connected to the cover plate 200. The cover plate 200 and the squeezing container 10 are then assembled, and each squeezing container 10 can have its own independent driving structure to drive its power-driven squeezing structure 400 to squeeze out toothpaste paste, or the same driving structure can be used to synchronously drive the power-driven squeezing structures 400 in the three squeezing containers 10 to squeeze out toothpaste paste, and the toothpaste pastes can be mixed when used.

[0093] Furthermore, two or three container bodies 100 having the same structure according to the above embodiment can be connected, for example, by connecting adjacent container bodies 100 with an adhesive or by fastening them with a screw connection, to form an integrated squeeze container 10. The squeeze container 10 having such a structure can be used to squeeze out toothpastes of two or three different ingredients, and the toothpastes can be mixed when used.

[0094] In some embodiments, as shown in FIG. 4 , one end of the partition plate 130 extends to the outlet 120 and the other end abuts the cover plate 200. One end of the partition plate 130 extends toward the outlet 120 and connects with the wall of the outlet 120 of the container body 100, while the other end extends toward the tail of the container body 100 and abuts the cover plate 200, which is connected to the tail of the container body 100. The abutment between the cover plate 200 and the partition plate 130 serves as a positioning mechanism during installation. The installation of the partition plate 130 and the interaction forces in two directions on the side wall of the container body 100 due to the connection structure 300 provide sufficient support for the power-driven squeezing structure 400, further improving the stability of the connection between the partition plate 130 and the container body 100, allowing the power-driven squeezing structure 400 to more automatically, stably, and efficiently squeeze material out of the outlet 120.

[0095] As shown in the embodiment of Fig. 4, an example will be described in which the container body 100 is divided into two parts by a single partition plate 130, and the container body 100 has an elliptical tubular structure. As shown in Figs. 5, 7, 8 and 9, the cover plate 200 has an elliptical structure that matches the shape of the container body 100 and has a uniform thickness.

[0096] In some embodiments, the material of the cover plate 200 is the same as the material of the container body 100, such as polypropylene (PP), polyethylene (PE), polystyrene (PS), polycarbonate (PC), polyethylene terephthalate (PETG), polylactic acid (PLA), etc.

[0097] As shown in FIGS. 3 and 4, the connection structure 300 is connected to the cover plate 200 and is engaged and connected to the container body 100.

[0098] 2 and 11, the container body 100 is provided with an engagement opening 112. For example, the engagement opening 112 is a groove or a hole provided in the container body 100.

[0099] 11 shows a connecting structure according to a first embodiment of the present invention. The connecting structure 300 includes an engaging element 310, one end of which is attached to the cover plate 200 and the other end of which is engaged with the engaging hole 112.

[0100] For example, the engaging member 310 is a protruding block integrally formed with the cover plate 200, and the protruding block is engaged in the engaging opening 112. In order to facilitate the connection between the cover plate 200 and the container body 100, in this embodiment, two engaging members 310 are provided, and the two engaging members 310 are symmetrically arranged at both ends of the cover plate 200, and correspondingly, two engaging openings 112 are also provided on the container body 100. In other embodiments, two or more engaging members 310 may be provided on the cover plate 200 according to specific design requirements. The number of engaging openings 112 on the container body 100 may be the same as the number of the engaging members 310.

[0101] In this embodiment, the container body 100 and the connecting structure 300 are engaged and connected, which makes it easy to remove the container body 100 and the cover plate 200 and simplifies the operation. The cover plate 200 is fixed to the wall of the chamber 110 of the container body 100 by pushing the cover plate 200 into the container body 100 and engaging the engaging members 310 of the cover plate 200 with the engaging openings 112 of the container body 100, and once the engaging members 310 are engaged with the engaging openings 112 of the container body 100, the positioning and fixing of the cover plate 200 and the container body 100 are achieved.

[0102] In some embodiments, the connection structure 300 further includes a positioning rib 320, which is provided on the end of the engaging member 310 that engages with the engaging opening 112. The provision of the positioning rib 320 can improve the stability of the connection between the engaging member 310 and the engaging opening 112. When a user removes the cover plate 200 from the container body 100, the user can press the positioning rib 320 while holding the engaging members 310 on both sides of the cover plate 200 at the position of the positioning rib 320 with one hand, and the positioning rib 320 will detach from the engaging opening 112, facilitating removal.

[0103] Furthermore, the engaging member 310 is bent in the extension direction of the container body 100 and formed as a curved arc-shaped structure 311, and a positioning rib 320 is provided on the end of the engaging member 310 that is spaced apart from the arc-shaped structure 311 and engages with the engaging opening 112. In this embodiment, the engaging member 310 is a member that is elastic and has an arc-shaped structure, and when a user removes the cover plate 200 from the container body 100, by holding the positioning ribs 320 on the engaging members 310 on both sides of the cover plate 200 with one hand and pressing the positioning ribs 320, the engaging member 310 can be quickly released from the engaging opening 112 because the engaging member 310 has a certain degree of elasticity, making removal easier.

[0104] 12(a), 12(b), and 12(c) show a connecting structure according to a second embodiment of the present invention. A first mounting hole 113 is provided in the container body 100, and a second mounting hole 230 is provided in the cover plate 200. The connecting structure 300 includes a first connecting member 330 that passes through the first mounting hole 113 and the second mounting hole 230 to connect the cover plate 200 and the container body 100.

[0105] In some embodiments, the first connecting member 330 is a screw, a thread structure is provided in the first mounting hole 113, and a thread structure is provided in the second mounting hole 230, and the screw penetrates the first mounting hole 113 and the second mounting hole 230 in order to fix the cover plate 200 and the container body 100 with a threaded connection.

[0106] In some other embodiments, the first connecting member 330 is a pin that passes through the first mounting hole 113 and the second mounting hole 230 in order to fixedly connect the cover plate 200 and the container body 100 .

[0107] In the above two embodiments, the structure of the connection structure 300 is simple, the user can easily operate it, and the connection method is simpler.

[0108] 13(a), 13(b), and 13(c) show a connecting structure according to a third embodiment of the present invention. The connecting structure 300 includes a first connecting portion 340 and a second connecting portion 350. The first connecting portion 340 is provided on the container body 100, and the second connecting portion 350 is provided on the cover plate 200. The first connecting portion 340 and the second connecting portion 350 are screw-connected. The connecting structure 300 according to this embodiment has a simpler structure and is easier for users to operate.

[0109] In some embodiments, the first connecting portion 340 is provided on the inner wall of the chamber 110 of the container body 100, and the second connecting portion 350 is provided on the end of the cover plate 200 that is close to the inner wall of the chamber 110 of the container body 100. In these embodiments, the container body 100 has a cylindrical tubular structure, and the cover plate 200 has a circular cover plate structure accordingly. The second connecting portion 350 is provided on the periphery along the thickness direction of the cover plate 200, and the first connecting portion 340 is provided along the circumferential direction on the inner wall of the chamber 110 of the container body 100. When installed, the connection between the first connecting portion 340 and the second connecting portion 350 is realized to connect the container body 100 and the cover plate 200.

[0110] 14(a), 14(b), and 14(c) show a connection structure according to a third embodiment of the present invention. The cover plate 200 is further provided with an attachment portion 240, which extends from the cover plate 200 to the outside of the container body 100, with at least a portion of the attachment portion 240 located outside the side wall of the container body 100. A first connection portion 340 is provided on the outside of the side wall of the container body 100, and a second connection portion 350 is provided on the attachment portion 240 located outside the side wall of the container body 100.

[0111] In this embodiment, the container body 100 has a cylindrical tubular structure, and the cover plate 200 has a circular cover plate structure. The cover plate 200 has a mounting portion 240 on its periphery along the thickness direction. When the cover plate 200 and the container body 100 are assembled, the mounting portion 240 extends out of the container body 100 and a portion of the mounting portion 240 is exposed to the outside of the side wall of the container body 100. When the first connecting portion 340 and the second connecting portion 350 are connected, the portion of the mounting portion 240 can support the outer wall of the container body 100, thereby allowing the cover plate 200 to be connected to the container body 100 from the outside of the side wall of the container body 100.

[0112] 13(b) and 14(b), in one embodiment, the first connecting portion 340 is provided with a female thread structure, and the second connecting portion 350 is provided with a male thread structure. In another embodiment, the first connecting portion 340 is provided with a male thread structure, and the second connecting portion 350 is provided with a female thread structure. In each of these two embodiments, the first connecting portion 340 and the second connecting portion 350 are screw-connected, allowing for easy attachment and detachment.

[0113] For example, in Figure 13(b), when positioning and attaching the container body 100 and the cover plate 200, the cover plate 200 is pushed into the container body 100 to connect the first connecting portion 340 and the second connecting portion 350, and then the container body 100 is rotated while holding the cover plate 200 to screw-connect the first connecting portion 340 on the inner wall of the chamber 110 of the container body 100 and the second connecting portion 350 on the cover plate 200, thereby realizing the attachment and connection of the container body 100 and the cover plate 200, and the operation is easier and simpler.

[0114] As an example, in Figure 14(b), when positioning and attaching the container body 100 and the cover plate 200, the cover plate 200 is pushed into the container body 100 and the mounting portion 240 is exposed to the outside of the container body 100, so that a part of the mounting portion 240 supports the outside of the side wall of the container body 100, and by rotating the container body 100 while holding the mounting portion 240, or by rotating the mounting portion 240 while holding the container body 100, the second connecting portion 350 in the mounting portion 240 and the first connecting portion 340 on the outer wall of the container body 100 are screwed together, thereby realizing the attachment and connection between the container body 100 and the cover plate 200 and making the operation easier and simpler.

[0115] 15, which is a schematic diagram of a drive-driven squeezing structure according to one embodiment of the present invention. The drive-driven squeezing structure 400 includes a drive member 410 and a piston 420. One end of the drive member 410 is movably connected to the cover plate 200. The drive member 410 is installed in the chamber 110 along the extension direction of the container body 100. The piston 420 is movably connected to the drive member 410. The drive member 410 drives the piston 420 to move forward or backward along the extension direction of the axis of the drive member 410, thereby achieving squeezing of material.

[0116] In this embodiment, the forward and reverse transmission of the transmission member 410 in the transmission squeezing structure 400 drives the piston 420 to move forward or backward along the extension direction of the axial line of the transmission member 410, thereby realizing automatic squeezing of the material in the chamber 110 by the piston 420.

[0117] 4 illustrates the structure of a squeeze container 10. A partition plate 130 is installed within the container body 100, dividing the chamber 110 of the container body 100 into two sections, forming two independent sub-chambers 111, each containing a toothpaste of a different composition. To achieve the automatic, synchronized squeezing of the toothpastes in the two sub-chambers 111 and the purpose of mixing them during use, the drive squeezing structure 400 of this embodiment includes two drive members 410 and two pistons 420, one drive member 410 and one piston 420 installed in each sub-chamber 111, and the two drive members 410 are synchronously rotatable, thereby enabling the two pistons 420 to advance or retreat synchronously and thereby achieving the automatic, synchronized squeezing of the toothpastes of different compositions in the two sub-chambers 111.

[0118] 7, 9, and 10, a through-hole 210 is formed in the cover plate 200, and a shaft mounting portion 220 is provided at the through-hole 210. As shown in FIG. 4, a transmission member 410 passes through the through-hole 210 and is rotatably connected to the shaft mounting portion 220. In this embodiment, two transmission members 410 are provided, and therefore two through-holes 210 are also provided in the cover plate 200. The cover plate 200 is fixedly connected to the container body 100, and the transmission member 410 rotates to transmit power, so that the transmission squeezing structure 400 is movably connected to the cover plate 200. Specifically, the transmission member 410 passes through the through-hole 210 in the cover plate 200 and is provided with the shaft mounting portion 220. The transmission member 410 is attached to the cover plate 200 and can transmit power to the piston 420 to drive the piston 420 forward or backward.

[0119] In some embodiments, as shown in Figures 9 and 10, a position limiting protrusion rib 221 is provided inside the shaft mounting portion 220. As shown in Figures 16 and 17, a position limiting recessed groove 411 that fits with the position limiting protrusion rib 221 is provided in a portion of the transmission member 410 that is located inside the shaft mounting portion 220.

[0120] In this embodiment, a position limiting protrusion 221 is provided around the entire inner periphery of the shaft mounting portion 220, and a corresponding position limiting groove 411 is provided around the entire periphery of the power transmission member 410. The engagement between the position limiting protrusion 221 and the position limiting groove 411 allows the power transmission member 410 to be connected relatively firmly to the inside of the shaft mounting portion 220 when transmitting power to the piston 420, thereby reducing the risk of the power transmission member 410 coming loose.

[0121] 10 , a groove 222 is formed in the shaft mounting portion 220 along the extension direction of the axis of the transmission member 410. The groove 222, which has a certain width in the radial direction, is opened in the shaft mounting portion 220 along the extension direction of the axis of the transmission member 410. The provision of the groove 222 gives the shaft mounting portion 220 a certain degree of elasticity, which contributes to the attachment of the transmission member 410, and also movably connects the transmission member 410 to the cover plate 200 through the engagement of the position limiting protruding rib 221 and the position limiting recessed groove 411.

[0122] 16, a transmission member 410 is attached to the shaft mounting portion 220 and has a male connection head 412 at the end extending from the cover plate 200. The male connection head 412 is for connecting to a drive structure.

[0123] 17, the transmission member 410 is attached to the shaft mounting portion 220 and has a female connection head 413 at the end extending from the cover plate 200. The female connection head 413 is for connecting to a drive structure.

[0124] In one embodiment, the driving structure is a driving motor for driving the transmission squeezing structure 400, and the output end of the driving motor is connected to the transmission member 410 of the transmission squeezing structure 400 by a connecting member. The driving structure transmits power to the transmission member 410, and the transmission member 410 transmits power to the piston 420 to drive the piston 420 forward or backward.

[0125] In the embodiment shown in Fig. 16, the shaft head of the transmission member 410 is a male connecting head which is an outwardly protruding polygonal protrusion base, so that the coupling part of the drive structure for connecting with the transmission member 410 is provided with a sleeve-shaped female connecting head which has an inwardly concave polygonal structure and a circular outer contour. In the embodiment shown in Fig. 17, the shaft head of the transmission member 410 is a sleeve-shaped female connecting head which has an inwardly concave polygonal structure and a circular outer contour, so that the coupling part of the drive structure for connecting with the transmission member 410 is provided with an outwardly protruding male connecting head in the shape of a polygonal protrusion base.

[0126] In the above two embodiments, the cross section of the male connection head 412 or the female connection head 413 is circular or polygonal. In one embodiment, as shown in Figure 18, the male connection head 412 or the female connection head 413 has a polygonal cross section, which can prevent the transmission member 410 from rotating in one direction on the cover plate 200 and contribute to the quick alignment and connection between the transmission member 410 and the drive structure.

[0127] Furthermore, as shown in FIG. 15, the transmission member 410 and the piston 420 are threadedly connected, with the transmission member 410 having a male thread structure and the piston 420 having a female thread structure, or the transmission member 410 having a female thread structure and the piston 420 having a male thread structure.

[0128] In one embodiment, the transmission member 410 is a screw or a screw shaft, the transmission member 410 is provided with a screw thread structure, the piston 420 is provided with a screw hole, the screw hole is provided with a screw thread structure, the transmission member 410 is inserted through the screw hole of the piston 420 and is threadedly connected to the piston 420. The piston 420 can move along the axial extension direction of the transmission member 410 without running idle. When the driving mechanism rotates the transmission member 410, the rotation of the transmission member 410 drives the piston 420 to move forward or backward in the axial extension direction of the transmission member 410, thereby squeezing or sucking toothpaste into or from the chamber 110.

[0129] In some other embodiments, the driving mechanism 400 is a driving push rod, and a piston 420 is installed at the end of the driving push rod. The driving push rod can push the piston 420 forward to achieve automatic squeezing of toothpaste.

[0130] In another embodiment, the power-driven squeezing mechanism 400 is driven by a cylinder, and a pushing element is installed on the piston rod of the cylinder, and the function of the pushing element is the same as that of the piston 420 in Fig. 15, both of which are for squeezing out toothpaste. The piston reciprocates linearly within the cylinder, driving the pushing element forward or backward to squeeze out or suck back toothpaste.

[0131] 19, piston 420 includes piston body 421 and skirt structure 422. Skirt structure 422 is provided on piston body 421 and is provided at an angle toward the inner wall of chamber 110. The thickness of skirt structure 422 can be set according to the material so that skirt structure 422 maintains appropriate elasticity. By providing skirt structure 422, good sealing properties are achieved between piston 420 and the inner wall of chamber 110, and the degree of freedom of movement of piston 420 can be ensured.

[0132] Furthermore, the end of piston body 421 away from cover plate 200 protrudes in the direction of the axis of transmission member 410 to form protrusion 4211, and the shape of protrusion 4211 matches the shape of the inner wall of container body 100 near outlet 120. Piston body 421 has an irregular shape that is not a perfect circle and is close to the shape of sub-chamber 111 separated by partition plate 130. Protrusion 4211, formed by the end of piston body 421 away from cover plate 200 protruding in the axial direction of transmission member 410, matches the shape of the inner wall of the front part of container body 100 near outlet 120. This allows the toothpaste in sub-chamber 111 to be squeezed out to the maximum when piston 420 is pushed to the front-most end of outlet 120 of container body 100, thereby reducing toothpaste waste.

[0133] In some embodiments, the outermost dimension of the inclined skirt structure 422 is larger than the dimension of the inner wall of the chamber 110. The skirt structure 422 is inclined outward at a certain angle with the piston 420, and the outermost dimension is larger than the inner dimension of the chamber 110 of the container body 100. With this design, there is a good sealing between the piston 420 and the inner wall of the chamber 110. When the transmission member 410 drives the piston 420 forward to squeeze out the toothpaste, the piston 420 presses the skirt structure 422 under pressure, and under the action of pressure, the skirt structure 422 is more firmly in contact with the inner wall of the chamber 110, and the piston 420 plays a role in sealing the chamber 110.

[0134] In one embodiment, the skirt structure 422 includes a first skirt structure 4221 and a second skirt structure 4222, where the first skirt structure 4221 is provided at an end of the piston body 421 away from the cover plate 200, and the second skirt structure 4222 is provided at an end of the piston body 421 close to the cover plate 200.

[0135] In this embodiment, when the transmission member 410 drives the piston 420 forward to squeeze out the toothpaste, the piston 420 is subjected to pressure and presses the first skirt structure 4221 and the second skirt structure 4222, and under the action of pressure, the first skirt structure 4221 and the second skirt structure 4222 are brought into closer contact with the inner wall of the chamber 110, thereby sealing the chamber 110. When the piston 420 retracts, the second skirt structure 4222 also comes into closer contact with the inner wall of the chamber 110, thereby also playing a sealing role, thereby improving the stability of the piston 420.

[0136] In another embodiment, as shown in Figures 20(a) and 20(b), the skirt structure 422 further includes a third skirt structure 4223, which is provided on the piston body 421 and positioned between the first skirt structure 4221 and the second skirt structure 4222.

[0137] In this embodiment, the third skirt structure 4223 is provided on the piston body 421 between the first skirt structure 4221 and the second skirt structure 4222, and is closer to the first skirt structure 4221. The third skirt structure 4223 may be a skirt structure formed along the circumferential direction of the piston body 421 and protruding toward the inner wall of the chamber 110.

[0138] When the transmission member 410 drives the piston 420 forward to squeeze out the toothpaste, the piston 420 receives pressure and presses the first skirt structure 4221 and the second skirt structure 4222, and under the action of pressure, the first skirt structure 4221 and the second skirt structure 4222 both come into closer contact with the inner wall of the chamber 110. When the transmission member 410 continuously drives the piston 420 forward, if the first skirt structure 4221 is pressed by the pressure, it may not be able to seal the paste, and in this case, the paste is likely to leak along the gap between the first skirt structure 4221 and the inner wall of the chamber 110 toward the tail of the container body 100. Because third skirt structure 4223 is provided at a position between first skirt structure 4221 and second skirt structure 4222, when leaking paste leaks along the gap between first skirt structure 4221 and the inner wall of chamber 110 toward the tail of container body 100, it first leaks toward third skirt structure 4223, which blocks the paste and prevents it from moving further toward second skirt structure 4222 and eventually leaking to partition plate 130. Therefore, in this embodiment, by providing third skirt structure 4223, the sealing performance of piston 420 can be further improved.

[0139] As a result, when the transmission squeezing structure 400 squeezes out toothpaste, the rotation of the two transmission members 410 drives the pistons 420 connected to each transmission member 410 to advance synchronously along the axial extension direction of the transmission members 410. When the driving structure that drives the transmission squeezing structure 400 outputs driving force uniformly, the driving structure drives the two transmission members 410, pushing the two pistons 420 to advance at a uniform speed, thereby making it possible to control the amount of toothpaste squeezed out.

[0140] As shown in Figure 21, a switch 500 and an insertion member 600 are installed on the container body 100, and the switch 500 and the insertion member 600 are electrically connected to each other, and the insertion member 600 is electrically connected to a conductive component in a stand that is assembled with the squeeze container 10 to transmit an electrical signal.

[0141] In this embodiment, a control unit, a power module, and a drive mechanism are installed in the stand. A switch 500 and an insert 600 electrically connected to the container body 100 are installed, so that the insert 600 is electrically connected to the control unit and the power module. The stand, equipped with the conductive components, is then connected to the squeeze container 10 for assembly. After the stand and the squeeze container 10 are assembled, the drive mechanism is connected to the transmission squeezing mechanism 400 in the squeeze container 10. When the user turns on the switch 500, the circuit between the squeeze container 10 and the stand is established. The control unit sends a control command to the drive mechanism based on the user's switch-on signal. The drive mechanism receives the command and drives the transmission squeezing mechanism 400 to operate, thereby rotating the transmission member 410 to drive the piston forward, thereby achieving automatic, synchronized squeezing of multiple ingredients with different compositions.

[0142] In some embodiments, the switch 500 is one of a membrane switch, a photoelectric switch, and a mechanical push button switch. For example, the membrane switch can be directly printed on the outer wall surface of the tube of the container body 100.

[0143] In some embodiments, as shown in FIG. 21, the container body 100 is provided with a groove 140, and the switch 500 is placed in the groove 140, with the surface of the switch 500 and the surface of the groove 140 closely aligned.

[0144] In this embodiment, a mechanical push button switch can be selected as the switch 500. A groove 140 is provided on the surface of the outer wall of the container body 100, and the mechanical push button switch is placed in the groove 140. The surface of the container body 100 is formed as a smooth surface at the location of the switch 500, thereby improving the overall aesthetic appearance of the container body 100.

[0145] 21 and 22, a wire is installed in the groove 140, and the switch 500 is electrically connected to the insertion member 600 through the wire. In this embodiment, the wire is connected to the mechanical push button switch, and the mechanical push button switch and the insertion member 600 transmit switch signals through a wired electrical connection.

[0146] In some other embodiments, the switch 500 and the insertion member 600 are connected via wireless communication, as shown in Fig. 23. In this embodiment, the switch 500 and the insertion member 600 are connected via wireless communication, which eliminates the need for winding and attaching wires and simplifies the structure of the switch 500.

[0147] 21 and 22, for example, the insert 600 is a metal insert block, and the corresponding conductive component installed on the stand to be assembled with the squeeze container 10 is a metal elastic piece. The metal elastic piece may be installed on the outer wall of the stand, on the inner wall of the stand, or on both the inner and outer walls of the stand. After the stand and squeeze container 10 are assembled, the insert 600 and the metal elastic piece on the stand are connected. When the user turns on the switch 500, the switch 500 and the insert 600 are electrically connected, establishing a circuit between the squeeze container 10 and the stand, thereby enabling the transmission of an electrical signal from the switch.
