Description

Technical Field

[0001] The present application relates to the field of container technology, and in particular to an ointment pump container. Background Art

[0002] Ointments are semi-solid substances with a certain consistency, widely used in medicine, cosmetics, food, and other fields. After the ointment is produced, it will be packaged in a suitable container according to its usage to facilitate subsequent sales and use.

[0003] Toothpaste is a common paste used in daily life. After production, toothpaste is usually packaged in a tube. When using, the tube is squeezed as needed to squeeze the toothpaste onto the toothbrush. However, with the continuous improvement of people's living standards, the quality of life is also getting higher and higher. The tube method of squeezing toothpaste can no longer meet people's demand for quality of life. Moreover, when the toothpaste is gradually used up, it is difficult to squeeze out the remaining toothpaste, which seriously affects the user experience.

[0004] To this end, the present application provides a convenient-to-use ointment pump container. Summary of the Invention

[0005] In order to improve the user experience when squeezing toothpaste, the present application provides a paste pump container, which can squeeze out toothpaste by simply pressing a button when in use.

[0006] The present application provides an ointment pump container adopting the following technical solution:

[0007] A paste pump container, comprising a cylindrical paste barrel, a cap detachably fixed to one end of the paste barrel, and a piston slidably disposed within the paste barrel, wherein a sealing ring sleeve is coaxially fixed to the circumference of the piston and seals against the inner wall of the paste barrel;

[0008] A paste outlet pipe for discharging the paste outward is fixed to the cover, and a one-way valve is installed on the paste outlet pipe; a one-way paste outlet assembly is provided inside the paste cylinder at an end close to the cover, the piston is located at an end of the one-way paste outlet assembly away from the air drying, and a paste storage chamber for storing the paste is formed between the piston and the one-way paste outlet assembly;

[0009] An elastic leather cup is also provided at the end of the paste tube close to the sealing cover, and the elastic leather cup is located at the end of the one-way paste discharge component away from the piston. A paste discharge cavity is formed between the elastic leather cup and the one-way paste discharge component, and the paste in the paste storage cavity can only enter the paste discharge cavity through the one-way paste discharge component; the paste discharge tube is connected to the paste discharge cavity; and a button for squeezing the elastic leather cup is provided on the sealing cover.

[0010] By adopting the above technical solution, a leather cup and a one-way paste outlet component are provided in the paste tube, and a paste outlet chamber is formed between the leather cup and the one-way paste outlet component. When the paste is in the paste tube, the button is pressed, and the button will squeeze the elastic leather cup, thereby increasing the pressure in the paste outlet chamber, squeezing the paste in the paste outlet chamber from the one-way valve, and the paste is output from the paste outlet tube; after releasing the button, the elastic leather cup returns to its original shape, so that negative pressure is formed in the paste outlet chamber. Since the one-way valve cannot input air into the paste outlet chamber, the paste in the paste storage chamber will be sucked into the paste outlet chamber, and the pressure in the paste storage chamber will drop. The atmospheric pressure will push the piston into the paste storage chamber, so that the piston can move with the paste, so that the paste storage chamber is always in a sealed constant pressure state; when in use, the paste in the paste tube can be squeezed out by simply pressing the button. It is easy to use and can effectively improve the user experience.

[0011] Optionally, the piston is a barrel structure with an opening at the lower end, the edge of the piston is connected to the middle of the sealing ring sleeve, the sealing ring sleeve arches toward the piston along the middle of the axial direction, and the upper and lower ends of the sealing ring sleeve are in contact with the inner wall of the paste tube.

[0012] By adopting the above technical solution, the sealing ring sleeve is set to a structure with an inward arch in the middle. During normal use, the atmospheric pressure pushes the piston to slide toward the inside of the paste tube, and the upper end of the sealing ring sleeve will scrape the paste inside the paste tube to prevent the paste from remaining on the inner wall of the paste tube; and when the pressure inside the paste storage chamber increases, the paste in the paste storage chamber pushes the piston downward, and the side wall of the piston will squeeze the middle part of the sealing ring sleeve toward the inner wall of the paste tube, thereby increasing the contact area between the sealing ring sleeve and the inner wall of the paste tube, and increasing the friction between the sealing ring sleeve and the paste tube, thereby preventing the piston from retreating during normal use.

[0013] Optionally, the one-way paste outlet assembly includes a partition, a fixed ring, and a valve elastically connected to the fixed ring; the partition is fixed on the inner wall of the paste tube, and a paste inlet hole is opened on the partition for the paste to pass through; the fixed ring is coaxially fixed to one end of the partition close to the elastic leather cup, and the valve is arranged to cover and seal the paste inlet hole.

[0014] By adopting the above technical solution, a partition and a valve are set in the paste tube to form a one-way conveying structure. When negative pressure is formed in the paste outlet chamber, the valve will be sucked into the paste outlet chamber, so that the paste inlet hole is connected to the paste outlet chamber, and the paste in the paste storage chamber is sucked into the paste outlet chamber; after the pressure in the paste outlet chamber and the paste storage chamber is restored to balance, the valve gradually returns to its original position to block the paste inlet hole under the action of elasticity. Even if the valve does not completely close the paste inlet hole, when the button is pressed to squeeze the paste outlet chamber, the pressure in the paste outlet chamber increases, which will press the valve tightly against the paste inlet hole, completing the normal output of the paste.

[0015] Optionally, the elastic leather cup is hemispherical, and the elastic leather cup is inverted on the partition; the elastic leather cup is fixed with a fixed sleeve at a position corresponding to the paste outlet tube, and the fixed sleeve is arranged on the paste outlet tube, and a check ring is coaxially fixed on the inner side of the fixed sleeve, and the inner side of the check ring is inclined toward the direction of leaving the paste outlet tube.

[0016] By adopting the above technical solution, the elastic leather cup is set to a hemispherical shape, so that a paste outlet cavity can be formed between the elastic leather cup and the partition, and it helps to improve the elastic performance of the elastic leather cup; a fixed sleeve is set on the elastic leather cup to facilitate connecting the paste outlet tube to the inside of the leather cup; a check ring is set on the fixed sleeve to prevent the fixed sleeve from slipping off the paste outlet tube, and at the same time can effectively improve the sealing between the fixed sleeve and the paste outlet tube.

[0017] Optionally, a card slot is provided on the inner wall of the paste cylinder corresponding to the installation position of the partition and the elastic leather cup, and the edges of the partition and the elastic leather cup are card-engaged in the card slot.

[0018] By adopting the above technical solution, a groove is provided on the inner wall of the paste cylinder, which facilitates the installation of the partition plate and the elastic leather cup.

[0019] Optionally, the one-way valve includes an elastic valve body coaxially fixed in the paste outlet tube, the elastic valve body is configured as an elastic barrel structure with an opening at one end, a paste outlet is opened at the end of the elastic valve body, and the side walls of the paste outlet are sealed to each other.

[0020] By adopting the above technical solution, a paste outlet is opened on the elastic valve body, and the side walls of the paste outlet fit together. During use, only when the internal pressure is greater than the elastic force of the side walls of the paste outlet can the paste push open the side walls of the paste outlet and be discharged externally. When the pressure approaches equilibrium, the paste outlet will be quickly closed again.

[0021] Optionally, the paste outlet is opened in a cross shape, and an inwardly recessed support portion is provided on the elastic valve body at a position corresponding to a central angle of the paste outlet.

[0022] By adopting the above technical solution, the paste outlet is opened in a cross shape, and a corresponding support part is provided, so that the end of the elastic valve body is tapered, making it easy for the internal paste to push open the paste outlet, and when pushing from the outside to the inside, the paste outlet will be pressed tighter and tighter, forming a one-way opening structure.

[0023] Optionally, a sealing sleeve is fixed on the paste outlet pipe to improve the sealing between the one-way valve and the paste outlet pipe.

[0024] By adopting the above technical solution, providing a sealing sleeve can effectively improve the sealing between the one-way valve and the paste outlet pipe, preventing leakage.

[0025] Optionally, the outlet of the paste discharge tube is inclined toward one side of the cover, and the button is located on the other side of the cover, and the button is hingedly fixed to the cover.

[0027] Optionally, a cover plate for sealing the paste outlet pipe is fixed to one end of the button close to the outlet of the paste outlet pipe.

[0028] By adopting the above technical solution, a cover plate is provided on the button. When the button is not pressed, the cover plate closes the outlet of the paste tube, thereby preventing external impurities from contaminating the paste.

[0029] Optionally, a protective cover is provided on one end of the paste tube close to the sealing cover.

[0030] By adopting the above technical solution, when not in use, the protective cover can protect the structure on the cover, thereby preventing external impurities from contaminating the paste.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. By arranging a leather cup and a one-way cream discharge component in the cream barrel, a cream discharge chamber is formed between the leather cup and the one-way cream discharge component. When the cream barrel is filled with cream, pressing the button will squeeze the elastic leather cup, increasing the pressure in the cream discharge chamber and squeezing the cream in the cream discharge chamber out of the one-way valve, and the cream is discharged from the cream discharge tube. After releasing the button, the elastic leather cup returns to its original shape, so that negative pressure is formed in the cream discharge chamber. Since the one-way valve cannot input air into the cream discharge chamber, the cream in the cream storage chamber will be sucked into the cream discharge chamber, and the pressure in the cream storage chamber will drop. The atmospheric pressure will push the piston into the cream storage chamber, so that the piston can move with the cream, so that the cream storage chamber is always in a sealed constant pressure state. When in use, the cream in the cream barrel can be squeezed out by pressing the button. It is easy to use and can effectively improve the user experience.

[0033] 2. A one-way conveying structure is formed in the paste barrel by setting a partition and a valve. When negative pressure is formed in the paste discharge chamber, the valve will be sucked into the paste discharge chamber, connecting the paste inlet hole to the paste discharge chamber, and the paste in the paste storage chamber will be sucked into the paste discharge chamber. After the pressure in the paste discharge chamber and the paste storage chamber is restored to equilibrium, the valve gradually returns to its original position under the action of elasticity to block the paste inlet hole. Even if the valve does not completely close the paste inlet hole, when the button is pressed to squeeze the paste discharge chamber, the pressure in the paste discharge chamber increases, pressing the valve against the paste inlet hole, completing the normal discharge of the paste;

[0034] 3. By opening the paste outlet on the elastic valve body into a cross shape and providing a corresponding support portion, the end of the elastic valve body is tapered, making it easy for the internal paste to push open the paste outlet. When pushing from the outside to the inside, the paste outlet will be pressed tighter and tighter, forming a one-way opening structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is combined with Figure 1-3 This application is described in further detail.

[0040] The present application embodiment discloses a cream pump container, referring to Figure 1 and Figure 2 The device comprises a paste barrel 1, a piston 2, a sealing cap 3, a button 31, and a protective cover 4. The paste barrel 1 is a cylindrical barrel, and the piston 2 is coaxially slidably mounted inside the paste barrel 1 and sealed against the inner wall of the paste barrel 1. The sealing cap 3 is detachably mounted on one end of the paste barrel 1 by means of threads or snaps. A paste outlet tube 32 is integrally formed on one side of the sealing cap 3, and a button 31 is located on the other side of the sealing cap 3 and is hingedly connected to the sealing cap 3. The protective cover 4 is mounted on the end of the paste barrel 1 near the sealing cap 3 and covers the sealing cap 3 for protection. During use, simply rotating and pressing the button 31 allows the paste in the paste barrel 1 to be squeezed out through the internal structure, making it convenient to use.

[0041] Reference Figure 2 and Figure 3An elastic leather cup 5 and a one-way paste discharge component 6 are provided at the end of the paste tube 1 close to the sealing cap 3. The elastic leather cup 5 is located on the side close to the paste discharge tube 32 and is connected to the paste discharge tube 32; the piston 2 is located on the side of the one-way paste discharge component 6 away from the elastic leather cup 5, and a paste storage chamber 11 for storing paste is formed between the one-way paste discharge component 6 and the piston 2; a paste discharge chamber 12 is formed between the elastic leather cup 5 and the one-way paste discharge component 6, the paste discharge tube 32 is connected to the paste discharge chamber 12, and a one-way valve 7 is installed in the paste discharge chamber 12.

[0042] During use, rotate and press the button 31, which will squeeze the elastic leather cup 5 downward, causing the pressure in the paste discharge chamber 12 to rise, and the paste in the paste discharge chamber 12 will be squeezed and output from the one-way valve 7 to the paste discharge tube 32, completing the paste discharge; after releasing the button 31, the elastic leather cup 5 will return to its original shape under its own elasticity. At this time, negative pressure will be formed in the paste discharge chamber 12, while the paste storage chamber 11 will be at normal pressure. The paste in the paste storage chamber 11 will push open the one-way paste discharge component 6 and enter the paste discharge chamber 12. At the same time, the external atmospheric pressure will also push the piston 2 to move upward to compensate for the space for the paste to be discharged.

[0043] The one-way paste-dispensing assembly 6 comprises a diaphragm 61, a retaining ring 62, and a valve 63 elastically connected to the retaining ring 62. The diaphragm 61 is a circular half-body coaxially fixed to the inner wall of the paste cylinder 1. A paste inlet hole 611 is coaxially formed through the diaphragm 61. The retaining ring 62 is coaxially fixed to the side of the diaphragm 61 near the elastic leather cup 5. The valve 63 is a circular plate. An elastic band 64 connects the circumference of the valve 63 to the retaining ring 62. The elastic member coaxially connects the valve 63 to the center of the retaining ring 62. In its free state, the valve 63 abuts against the paste inlet hole 611, sealing it.

[0044] When the pressure in the paste outlet chamber 12 increases, the valve 63 will be pressed tightly against the paste inlet hole 611 for sealing. When negative pressure is formed in the paste outlet chamber 12, the valve 63 will be sucked into the paste outlet chamber 12, allowing the paste in the paste storage chamber 11 to enter the paste outlet chamber 12.

[0045] The elastic leather cup 5 is configured in a hemispherical shape and is inverted onto the one-way paste outlet assembly 6. A fixing sleeve 51 is coaxially and integrally formed at the position of the elastic leather cup 5 corresponding to the paste outlet tube 32, and the fixing sleeve 51 is sleeved on the paste outlet tube 32. A check ring 52 is coaxially and integrally formed on the inner wall of the fixing sleeve 51. The inner side of the check ring 52 is tilted in the direction of separation from the paste outlet tube 32, which can effectively prevent the fixing sleeve 51 from sliding off the paste outlet tube 32. A clamping groove 13 is provided on the inner wall of the paste barrel 1 corresponding to the installation position of the leather cup and the partition 61. The edges of the elastic leather cup 5 and the partition 61 are clamped and fixed in the clamping groove 13.

[0046] The one-way valve 7 includes an elastic valve body 71. The elastic valve body 71 is a barrel structure made of elastic material with an opening at the lower end. The elastic valve body 71 is coaxially inserted into the paste outlet tube 32. A sealing groove 321 is coaxially provided on the inner wall at the lower end of the paste outlet tube 32. A limiting ring protrusion 74 is coaxially formed and integrally formed at the lower end of the elastic valve body 71. The limiting ring protrusion 74 is snapped into the sealing groove 321 to prevent the elastic valve body 71 from being displaced during use. A cross-shaped paste outlet 72 is provided through the upper end plane of the elastic valve body 71, and the side walls of the paste outlet 72 are sealed against each other. At one end of the elastic valve body 71 close to the paste outlet 72, corresponding to the four corners of the center of the paste outlet 72, a support portion 73 is formed inwardly. During use, the support portion 73 can support the paste outlet 72 so that the paste outlet 72 will be opened when the paste in the paste outlet cavity 12 is squeezed; when the paste outlet 72 is squeezed in the reverse direction, the support portion 73 will support the paste outlet 72 so that the paste outlet 72 will be squeezed inward and sealed, forming a one-way paste outlet structure.

[0047] A sealing sleeve 8 is installed on the paste outlet tube 32 at a position corresponding to the one-way valve 7. The sealing sleeve 8 is coaxially inserted into the end of the paste outlet tube 32 near the sealing groove 321. The end of the sealing sleeve 8 near the one-way valve 7 extends into the one-way valve 7. A ring protrusion is integrally formed at the position of the sealing sleeve 8 corresponding to the sealing groove 321. The ring protrusion is inserted into the sealing groove 321, which effectively improves the sealing between the sealing sleeve 8 and the paste outlet tube 32. A sealing ring protrusion 81 is integrally formed at the position of the sealing sleeve 8 near the end of the paste outlet tube 32. The sealing ring protrusion 81 is mounted on the end of the paste outlet tube 32 located inside the elastic leather cup 5, effectively preventing the paste from entering between the sealing sleeve 8 and the paste outlet tube 32.

[0048] A sealing ring sleeve 21 is coaxially and integrally mounted around the piston 2. Both are made of an elastic material. The piston 2 is configured as a barrel with an open lower end, while the sealing ring sleeve 21 is configured as a substantially cylindrical sleeve. The edge of the piston 2 opening is connected to the middle of the sealing ring sleeve 21 along the axis. The sealing ring sleeve 21 arches axially toward the piston 2 from its middle position, ensuring that the upper and lower ends of the sealing ring sleeve 21 are in contact with the inner wall of the paste barrel 1.

[0049] During normal use, the pressure inside the paste barrel 1 decreases, and atmospheric pressure pushes the piston 2 to slide toward the inside of the paste barrel 1. The upper end of the sealing ring sleeve 21 scrapes the paste inside the paste barrel 1 clean, preventing any paste from remaining on the inner wall of the paste barrel 1, while forming a seal with the inner wall of the paste barrel 1. When the pressure inside the paste storage chamber 11 increases, the paste in the paste storage chamber 11 pushes the piston 2 downward, and the side wall of the piston 2 squeezes the middle part of the sealing ring sleeve 21 toward the inner wall of the paste barrel 1, thereby increasing the contact area between the sealing ring sleeve 21 and the inner wall of the paste barrel 1 and increasing the friction between the sealing ring sleeve 21 and the paste barrel 1, thereby preventing the piston 2 from retreating during normal use.

[0050] A cover plate 311 is integrally formed at the end of the button 31 near the outlet of the paste tube 32. When the button 31 is free, the cover plate 311 rests on the end of the paste tube 32, sealing it and preventing foreign matter from entering the paste. A seal 312 is fixed to the outer wall of the button 31, near the end of the button 31 away from the cover plate 311. The product is shipped with the seal 312 attached, which needs to be removed before use, making it easy to check whether the purchased product has been used.

[0051] The implementation principle of a paste pump container disclosed in an embodiment of the present application is: by setting an elastic leather cup 5, a one-way paste discharge component 6 and a one-way valve 7, the cavity in the paste tube 1 is divided into a paste storage chamber 11 and a paste discharge chamber 12. When the elastic leather cup 5 is pressed by the button 31, the paste in the paste storage chamber 11 will be squeezed and output from the one-way valve 7. When the elastic leather cup 5 is reset, the paste in the paste storage chamber 11 can be sucked into the paste discharge chamber 12. The overall structure is simple and easy to use, which can effectively improve the user experience.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
