Description

Technical Field

[0001] The invention relates to the technical field of packaging bottles, in particular to a novel paste packaging bottle. Background Art

[0002] The packaging bottle is a commonly used packaging container in the cosmetics field, which is used to load fluid cosmetics, such as toothpaste. It is mostly made of ceramic, aluminum tube or plastic. Aluminum tube toothpaste is a product of the old era. With the continuous development of society and economy, aluminum materials are becoming more and more expensive, and the quality requirements of aluminum tubes are extremely high. The finished aluminum tubes must not have slight blisters. Since the 1980s, it has been gradually replaced by aluminum-plastic composite tubes. Aluminum-plastic tubes are a great industry revolution. They have both the high barrier properties of aluminum tubes and the lightness and low cost of plastic hoses. However, the biggest disadvantage is that aluminum and plastic (lids) are glued together in one package, which cannot be disassembled, recycled, and completely environmentally unfriendly. Therefore, global toothpaste brand manufacturers do not touch on the topic of packaging environmental protection. In recent years, the global environmental awareness has been increasing, so there is a new toothpaste packaging upright tube, but there is also a metal spring. The packaging needs to be disassembled and recycled. Later, our all-plastic upright cylinder packaging has also developed. The future goal should be that the entire set of toothpaste packaging is made of a single plastic material. Of course, the development path is estimated to be tortuous and there is a long way to go.

[0003] Hard plastic upright tube toothpaste is a form of toothpaste packaging that has become increasingly popular in recent years. Compared with traditional tube toothpaste, it has some unique advantages and features. The upright design allows the toothpaste to be easily placed on the sink, and the push-type dispensing device makes it more convenient to use, especially suitable for one-handed operation. The push-type operation can avoid waste, prevent leakage, and reduce pollution. The current pressing and discharging methods can be divided into spring piston type or straight cylinder pressing type. For example, application number 2024202247671 discloses a method of squeezing out fluid by pressing a soft capsule. However, in actual use, the applicant found that the single-body soft capsule structure is pressed and discharged. Due to the limitation of the elastic force of the single soft capsule itself, the speed of extruding the material is slow. Secondly, when pressing and discharging, the fluid is filled in the soft capsule, which makes it difficult to press the soft capsule to compress and deform it. A large pressing force needs to be applied, and the user experience is not good. In addition, the original single soft capsule extrusion discharging design has insufficient sealing and the number of times the pump is started when pressing and discharging is not accurate, so further improvement is needed. Summary of the invention

[0004] Based on this, it is necessary to provide a new paste packaging bottle to address the above problems.

[0005] A novel paste packaging bottle comprises a bottle body, wherein a piston is arranged in the bottle body, and the piston is movably arranged. A connecting seat is detachably installed at the bottle mouth of the bottle body, a pressing head is movably installed at the upper end of the connecting seat, a soft capsule is installed in the connecting seat, the soft capsule comprises a lower soft capsule body, an upper soft capsule body, a fluid channel and a diaphragm, the lower soft capsule body and the upper soft capsule body are connected by a diaphragm, the lower end of the lower soft capsule body is clamped on the bottom of the connecting seat, a one-way valve is arranged at the bottom of the connecting seat, the fluid channel is arranged in the upper soft capsule body, the fluid channel is connected with the bottle body through the lower soft capsule body, the tube wall of the fluid channel is movably inserted in the airtight tube of the pressing head, the outer wall of the tube wall is fitted with the inner wall of the airtight tube, a discharge hole is arranged on the side wall of the tube wall, the airtight tube movably blocks the discharge hole, and the airtight tube is connected with the outside through the discharge pipe.

[0006] Preferably, the upper end surface of the pressing head is provided with frosted patterns or a convex dot array.

[0007] Preferably, a notch is provided at an edge of the spacer, and a guide strip is provided on the inner wall of the pressing head corresponding to the notch.

[0008] Preferably, the soft capsule is bi-conical.

[0009] Preferably, the diameters of the upper and lower soft capsule bodies of the soft capsule decrease gradually towards each other.

[0010] Preferably, a snap ring is provided at the lower end of the lower soft capsule body, and a snap groove is provided at the inner bottom of the connecting seat corresponding to the snap ring.

[0011] Preferably, a stop ring is provided at the upper end port of the connecting seat, and a stepped platform is provided on the outer peripheral surface of the pressing head corresponding to the stop ring.

[0012] Preferably, the bottom of the bottle body is detachably provided with a skirt.

[0013] Preferably, a plurality of exhaust grooves are provided on the outer peripheral surface of the pressing head.

[0014] Preferably, an exhaust hole is provided on the upper soft bladder body.

[0015] The benefits of the present invention lie in: the two-section soft-bag structure provides sufficient elastic force, and utilizes the cooperation between the airtight tube and the tube wall of the fluid channel to produce an airtight function, which can completely block the discharge hole, so that the bottle body maintains a vacuum state when no pressing force is applied, and the fluid discharge is more stable when pressed; the two-section integrated soft-bag structure replaces the original multiple scattered components, effectively reducing the number of overall product components, simple assembly, stronger reliability, and longer service life; the soft-bag material can be consistent with other materials to achieve full plastic assembly, without the need for components of other materials, and does not need to be disassembled for classification and recycling when discarded, which is more environmentally friendly; and when pressed, since the fluid is filled in the lower soft-bag body and the airtight pipe, it is only necessary to deform the empty upper soft-bag body, which saves more effort and improves the user experience.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figures 1 to 3As shown, a new paste packaging bottle includes a bottle body 1, a piston 2 is arranged inside the bottle body 1, and the piston 2 is movably arranged. A connecting seat 3 is detachably installed at the bottle mouth of the bottle body 1, which can be specifically connected by screw threads for easy disassembly and assembly. The pressing head 4 is movably mounted on the upper end of the connecting seat 3, and a soft capsule 5 is installed in the connecting seat 3. The soft capsule 5 includes a lower soft capsule body 51, an upper soft capsule body 52, a fluid channel 53 and a diaphragm 54. The lower soft capsule body 51 is connected to the upper soft capsule body 52 through the diaphragm 54, and the lower end of the lower soft capsule body 51 is clamped on the bottom of the connecting seat 3. A one-way valve 31 is provided at the bottom of the connecting seat 3. The fluid channel 53 is arranged in the upper soft capsule body 52, and the fluid channel 53 is connected with the bottle body 1 through the lower soft capsule body 51. The tube wall 531 of the fluid channel 53 is movably inserted in the airtight tube 41 of the pressing head 4, and the outer wall of the tube wall 531 is fitted with the inner wall of the airtight tube 41. A discharge hole 532 is provided on the side wall of the tube wall 531, and the airtight tube 41 movably blocks the discharge hole 532. The airtight tube 41 is connected with the outside through the discharge tube 411. Specifically, in the present embodiment, when the user needs to squeeze out the fluid for use, he only needs to apply a pressing force on the pressing head 4, and the pressing head 4 can transmit the force to the soft capsule 5, causing the soft capsule 5 to deform. At this time, the discharge hole 532 at the upper end of the tube wall 531 of the fluid channel 53 in the upper soft capsule body 52 is connected to the discharge pipe 411 on the airtight tube 41, and because the lower soft capsule body 51 is deformed under pressure, the pressure in its capsule cavity increases, and the one-way valve 31 of the connecting seat 3 is closed at this time to prevent the fluid from flowing back into the bottle body 1. The fluid filled in the lower soft capsule body 51 can only flow upward along the tube wall 531 of the fluid channel 53, and flow out from the discharge hole 532 to the discharge pipe 411, and be squeezed out to the outside for use. When the pressing stops, the soft capsule 5 is made of elastic material and has elasticity. The soft capsule 5 recovers under the action of its own elastic force. Since the outer wall of the tube wall 531 fits the inner wall of the airtight tube 41, the discharge hole 532 at the upper end of the tube wall 531 of the fluid channel 53 in the upper soft capsule body 52 and the discharge tube 411 on the airtight tube 41 are blocked again to form a seal, and a negative pressure state is formed in the fluid channel 53 and the lower soft capsule body 51. The external atmospheric pressure enters through the bottom of the bottle body 1, driving the piston 2 to move upward along the inner wall of the bottle body 1, and the fluid can flush the one-way valve 31. The fluid in the bottle body 1 can be sucked into the lower soft capsule body 51 and the fluid channel 53 under the action of atmospheric pressure, and the upper soft capsule body 52 recovers synchronously. The tube wall 531 on the fluid channel 53 forms a seal with the inner wall of the airtight tube 41 to prevent the fluid from overflowing.When pressed, the upper soft capsule 52 is compressed, and the upper end of the fluid channel 53 leaks out. At this time, the discharge hole 532 leaks out and can serve as a valve for the fluid to flow to the outside, so there is no need to arrange another one-way valve on the fluid channel 53, saving costs; the double-section soft capsule structure can provide sufficient elastic force for the pumped fluid, making the fluid discharge faster, and using the airtight tube 41 to cooperate with the tube wall 531 of the fluid channel 53 to produce an airtight function, which can completely block the discharge hole 532, so that the bottle body maintains a vacuum state when no pressing force is applied, and the fluid discharge is more stable when pressed. And when pressed, because the fluid is filled in the lower soft capsule 51, it is only necessary to deform the empty upper soft capsule 52, which is more labor-saving and improves the user experience. The two-section integrated soft bladder structure replaces the original multiple scattered parts, effectively reducing the number of overall parts of the product, making it simple to assemble, more reliable and longer-lasting. The soft bladder material can be consistent with other materials to achieve full plastic assembly, without the need for parts made of other materials. It does not need to be disassembled for classified recycling when discarded, which is more environmentally friendly. Moreover, when pressed, since the fluid is filled in the lower soft bladder body 51, it is only necessary to deform the empty upper soft bladder body 52, which saves effort and improves the user experience.

[0024] Specifically, the upper end surface of the pressing head 4 is provided with frosted patterns or a convex dot array, and when the user applies a pressing force on the pressing head 4 with his fingers, the friction is increased and it is not easy to slip.

[0025] like Figures 2-3 As shown, a notch 541 is provided on the edge of the spacer 54, and a guide bar 42 is provided on the inner wall of the pressing head 4 corresponding to the notch 541. Specifically, the guide bar 42 clamps the spacer 54 through the notch 541, so that when the entire soft bag 5 is deformed and displaced up and down under pressure, it can only move vertically up and down along the guide bar 42 without deflection.

[0026] like Figures 2-3 As shown, the soft capsule 5 is a double cone, which allows the fluid to flow from the lower soft capsule body 51 to the fluid channel 53 during circulation, which is convenient for accurate discharge, reduces the residual fluid in the lower soft capsule body 51, and increases the discharge speed.

[0027] like Figures 2-3 As shown, the diameters of the upper soft capsule 52 and the lower soft capsule 51 decrease gradually, and the upper soft capsule 52 and the lower soft capsule 51 are in the shape of a spiral cone. When the diameters of the upper soft capsule 52 and the lower soft capsule 51 gradually decrease toward one end of the partition 54, a double cone is formed. After the lower soft capsule 51 and the upper soft capsule 52 are deformed under pressure, the cushioning performance is stronger, thereby reducing the risk of the lower soft capsule 51 and the upper soft capsule 52 being damaged under pressure, resulting in fluid leakage.

[0028] like Figures 2-3As shown, a clamping ring 511 is provided at the lower end of the lower soft capsule body 51, and a clamping groove 32 is provided on the inner bottom of the connecting seat 3 corresponding to the clamping ring 511. Specifically, the clamping groove 32 cooperates with the clamping ring 511 to clamp the lower soft capsule body 51, so as to prevent the lower soft capsule body from being separated from the connecting seat 3, resulting in fluid leakage outside the soft capsule.

[0029] like Figures 2-3 As shown, a bottle cap 6 is also included, and the bottle cap 6 can be detachably mounted on the outside of the connecting seat 3. The bottle cap 6 is used to protect the pressing head 4 to prevent the outlet pipe 411 of the pressing head 4 from leaking out, thereby reducing the probability of contamination and preventing the pressing head 4 from being pressed by mistake, resulting in fluid leakage.

[0030] like Figures 2-3 As shown, the upper end port of the connection seat 3 is provided with a stop ring 33, and the outer circumferential surface of the pressing head 4 is provided with a stepped platform 43 corresponding to the stop ring 33. Specifically, the stop ring 33 cooperates with the stepped platform 43 to clamp the pressing head 4 to prevent the pressing head 4 from being separated from the connection seat 3, and other components such as latches are not required, thereby reducing the number of product parts and reducing the difficulty of assembly.

[0031] Specifically, in this embodiment, the bottom of the bottle body 1 is detachably provided with a skirt 7, which is made of rubber and can be sleeved or adhered to the bottom of the bottle body 1. When the bottle body 1 is placed vertically on a table, the skirt 7 can be adsorbed on the table, and the vertical placement is more stable and not easy to tip over.

[0032] Specifically, a plurality of exhaust grooves 44 are provided on the outer peripheral surface of the pressing head 4 , and the exhaust grooves are connected to the discharge pipe 411 , so that the exhaust can be discharged more quickly, making it convenient to press the pressing head 4 .

[0033] like Figure 2 As shown, an exhaust hole 521 is provided on the upper soft capsule body 52. ​​Since the upper soft capsule body 52 is in contact with the pressing head 4, during the process of the upper soft capsule body 52 being compressed and deformed, if the sealing performance between the upper soft capsule body 52 and the pressing head 4 is too good, the gas inside is not easy to be discharged, which will cause poor operation. Further, an exhaust hole 521 is provided on the upper soft capsule body 52 to avoid the above problem and make pressing more labor-saving.

[0034] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
