Abstract

A paste taking component (1) and a package for quantitatively taking a paste comprising the component. The paste taking component (1) comprises a taking cover (3) capable of moving while clinging to the paste. The taking cover (3) is provided with a lower surface (32) attached to the paste and an upper surface (31) opposite to the lower surface (32). A taking opening (34) penetrates the upper surface and the lower surface. To take the paste, the taking cover (3) moves while clinging to the paste and forces the paste to be discharged from the taking opening (34). A limiting structure (7) is arranged in the outer peripheral surface of the taking cover (3) and interacts with an inner wall (23) of a container to forcibly make the taking cover vertical to an axial direction of the container and/or parallel to a support surface at the bottom of the container regardless of whether the taking cover is still or moves while clinging to the inner wall (23)of the container. When subjected to force, the taking cover (3) only translationally moves up and down along the inner wall of the container or translationally moves up and down and rotates about the axis. The component (1) ensures that the taking cover (3) does not incline or lift and squeeze the paste out from the cover edge, thereby preventing the device from becoming invalid because the paste is discharged from the cover edge.

Description

Paste access components and packaging

This application relates to paste dispensing assemblies and packaging.

Background technique

Traditional pastes (including lotions, etc.) are widely used in cosmetic containers. When they are taken, they are taken directly by hand, so they are unsanitary, and the bacteria on the hands easily contaminate the remaining paste in the container. Therefore, the wide-mouth container has not been widely used in the field of paste packaging, and a large number of containers are currently used. However, because the small-mouth container requires the container to be a soft body, plastic containers are widely used at present, and such small-mouth plastic containers are not convenient to operate (such as inconvenient to place, usually need to be inverted, need to be squeezed and hands-operated, etc.) Moreover, the container can not be reused, which is easy to cause environmental pollution, but it is popular because of its hygiene and the difficulty of contaminating the internal paste of the container.

British Patent Document GB385182A discloses a paste body assembly which can be used for a wide-mouth container, which comprises a blade c and a disk-shaped access cover a which can be rotated against the paste. When taken, the user presses and rotates. The cover a, the cover a is pressed against the paste and rotated, and the paste enters the access opening along the shovel surface. The solution avoids the problem that the bacteria on the hand easily contaminate the paste when the paste is taken from the wide mouth container, but still has the following disadvantages: when the user's finger is pressed down and rotated to take the cover, because of the manual operation Natural limitations, can not guarantee uniform force on the upper surface of the entire access cover, when the upper surface of the cover is unevenly stressed, because the paste material under the cover has fluidity, the disk-shaped cover will inevitably occur Tilting and lifting, resulting in a large gap between the edge of the access cover and the inner wall of the container. The paste material is squeezed out of the gap under the pressure of the cover body, thereby causing the entire device to fail. This is also the key reason why this program was proposed from 1921 until now.

Since then, people have been striving to propose various improvements, but there is no perfect solution to effectively solve the problem of contaminating paste when it is taken, making it difficult for the wide-mouth container to be popular in the field of paste packaging.

detailed description

Embodiment 1:

As shown in Figs. 1, 4, the paste take-up package of this embodiment comprises a paste take-up assembly 1 and a container 2, a top cover 5, and the top cover 5 is detachably connected to the container opening 21 of the container 2.

As shown in Figures 2, 3, 6, and 9, the paste-receiving assembly 1 includes a take-up cover 3 to which the paste 6 can be attached, and the take-up cover 3 is embodied as a rotary cover 3 in this example. The rotary cover 3 has a lower surface 32 attachable to the paste 6, and an upper surface 31 opposed thereto, and an outer peripheral surface 33 connecting the upper surface 31 and the lower surface 32. An access opening 34 is formed through the upper surface 31 and the lower surface 32, and a blade 4 is provided below the access opening 34. The blade 4 is formed integrally with the rotating cover. The blade 4 has a scooping surface facing the take-up cover 3 and for guiding the paste 6 into the access opening 34; as shown in FIG. 12, the access opening 34 has a first opening edge 35 And the second opening edge 36, the first opening edge 35 and the second opening edge 36 are opposite to each other, and the blade 4 is fixed to the first opening edge 35 side of the access cover 3 and to the second opening The side 36 is laterally extended, and the first opening edge 35 and the second opening edge 36 are sequentially disposed along the rotation direction of the access cover 3, and the front end of the spade surface is lower than the second opening edge 36 side. The lower surface 32, when taken, the access cover 3 is rotated against the paste body 6, and the paste body 6 enters the access opening 34 along the shovel surface and continues to enter the upper surface 31 of the rotary cover. .

As shown in Figures 7, 8, and 11, the container 2 has a container opening 21, a container bottom surface 24 opposite the container opening, and a container inner wall 23, and a container bottom support surface 22. The container 2 is a cylindrical container having an axis 8, and the bottom support surface 22 of the container is perpendicular to the axis 8.

As still shown in Figures 2, 3, 6, and 9, the rotating cover outer peripheral surface 33 has a restraining structure 7: the limiting knot The structure 7 is an annular support body extending in the vertical direction on both sides of the outer edge of the take-up cover 3, so that the outer cross-sectional contour of the rotary cover 3 is "H" shaped. The restricting structure 7 interacts with the inner wall 23 of the container to form a side contact surface 33' which forms a lateral supporting force on the contact surface, forcing the rotating cover 3 to move when it is stationary or against the inner wall 23 of the container. They are all perpendicular to the direction of the container axis 8 and parallel to the bottom support surface 22 of the container; that is, during the forced movement, only the up and down translational movement along the inner wall 23 of the container and the rotational movement about the axis 8 occur.

The side contact surface 33' of the restraining structure 7 formed with the inner wall 23 of the container, as shown in Figures 23, 24, on the side contact surface 33', between the two effective contact points furthest in the vertical direction The distance is the limit height h, the height h is 8.0 mm, the diameter Z of the access cover 3 is 50.0 mm, and the ratio of Z to h is 100:16.

As a workaround, when h and 〖 are other values, the limit height h is required to be not less than 2.0 mm, on the basis of which the maximum diameter of the cover or the diagonal I and the limit height h are The ratio is not more than 100:5. Preferably, the height h is not less than 3.0 mm, and the ratio of the maximum diameter of the cover or the diagonal I to the height h is not more than 100: 10 (the smaller the ratio) The more effective the effect is to limit the function of the mechanism, the limit is h is equal to the depth of the container 2) to ensure that sufficient lateral support force is formed at the side contact surface 33', and the access cover 3 can be forced to be perpendicular to the container axis 8 direction. Or parallel to the bottom support surface 22 of the container.

As shown in FIGS. 5 and 10, the paste-receiving component 1 further includes a soft protective cover 10, and the soft protective cover 10 has a disk shape, and the protective cover 10 is fixedly disposed on the upper surface 31 of the access cover 3. The protective cover 10 is formed with a cantilever-shaped protective sheet 17 that is swingable. As shown in FIGS. 20 and 22, the protective cover 10 has a first state and a second state. In the first state, the cantilever-shaped protective sheet 17 covers the access opening 34 and can be anointed. The adhesive body of the body 6 is bonded to the access opening 34. In the second state, the cantilever-shaped protective sheet 17 is lifted by the pressing force of the paste 6 and is separated from the access opening 34.

As shown in FIG. 13-17, the paste picking assembly 1 further includes an annular elastic structure formed on the upper and lower edges of the restricting structure 7, and a thin-walled eaves-like structure 37 with elasticity. The container 3 is placed in the container. The state before 2 is as shown in Fig. 16. After the take-up cover 3 is loaded into the container 2, the elastic thin-walled eaves 37 is deformed by the inner wall 23 of the container, and is pressed outwardly against the inner wall 23 of the container, thereby sealing the paste 6 in the container 2. The optimum condition of the elastic thin-walled eaves 37 is that it is disposed on the lower edge of the restraining device (or both the upper and lower edges), and the thin-walled eaves 37 is slightly convex outward and has a certain elasticity. This elastic structure has a certain rigidity and a limited deformation range, and does not significantly affect the function of the restriction structure 7.

As shown in Figures 2, 3, 7, and 11, after the paste assembly 1 and the container 2 are assembled, the rotary cover 3 is mounted. Inside the container 2, the lower surface 32 of the rotating lid is attached to the paste 6, and the top cover 5 is screwed to the container opening 21 of the container 2. The rotary cover seals the paste 6 between the rotary cover 3 and the bottom surface 24 of the container and the inner wall 23 of the container.

As shown in Figure 18-22, when it is taken out, the top cover 5 is unscrewed, the handle 30 is held, and the rotary cover 3 is rotated. During the rotation, the rotary cover is moved against the paste 6, and the blade 4 shovels the paste 6 The paste body 6 enters the access opening 34 along the shovel surface 41, and is lifted upward to bring the cantilever-shaped protective sheet 17 into the second state. The paste body 6 is discharged from the access opening 34 and enters the access cover 3. The surface 31 is for the user's finger 100 to erase and take. During the take-up process, under the pressure of the finger 100 squeezing, the cantilever-shaped protective sheet 17 returns to the first state, and the paste 6 remaining by the take-up opening 34 is bonded to the rotary cover. It can be seen that the finger 100 wipes the paste 6 over the cantilever-shaped protective sheet 17 to obtain the access, and does not directly contact the paste 6 under the protective cover. After each take-up, the cantilever-shaped protective sheet 17 can be accessed. The adhesive of the residual paste 6 of the opening 34 is attached to the access opening 34, and it is more difficult for the finger 100 and the outside air to directly contact the paste 6 below the access opening 34, reducing the chance of bacterial contamination.

During this process, due to the action of the restraining structure 7, the rotating cover only undergoes up and down translational movement along the inner wall 23 of the container and rotational movement about the axis 8 to ensure that the paste 6 is not squeezed from the edge of the cover. Tilting or lifting, to prevent the paste material from being discharged from the edge of the cover to disable the device, ensuring reliability and sustainability.

In addition to the following embodiments 2, 3, and 4, various modifications can be made in this embodiment, for example: the container 2 may not be cylindrical, and may not even be rotationally symmetrical, so that there is no axis 8, when there is no axis 8. The access cover 3 is kept parallel to the container bottom support surface 22. The access cover 3 may not be a rotating cover, but may be adapted to any shape of the inner cavity of the container. At this time, the access cover 3 only moves up and down and does not rotate.

The bottom support surface 22 of the container may be inclined (relative to the surface of the paste 6 in a freely placed state), in which case the access cover 3 is not parallel to the container bottom support surface 22 but perpendicular to the container axis 8 direction.

Embodiment 2:

As shown in FIGS. 25-33, the paste taking package of the present embodiment is different from that of the first embodiment in that the restricting structure 实现 is realized by providing three pillars on the rigid skeleton 9, and the outer edge of the rigid skeleton 9 A thin soft elastomer 13 is provided, the pillar and the soft elastomer 13 are in contact with the inner wall 23 of the container to form a side contact surface 33', and the lower edge of the outer edge of the soft elastomer 13 also has a thin-walled eave structure. 37. The side contact faces 33' in the first embodiment are continuous regular strips, and the side contact faces 33' in this embodiment are irregular. After the take-up cover 3 is loaded into the container 2, the soft elastic body 13 and its lower edge elastic thin-walled eaves 37 are radially deformed by the inner wall 23 of the container, and the inner wall 23 of the container is pressed outward. The paste 6 is sealed in the container 2.

The pillars and the hard skeleton 9 ensure the rigidity of the structure 限制, while the thinner soft elastomer 13 has a limited range of deformation, which ensures a seal without a large influence on the rigidity of the restraining structure 7.

When the paste body 6 is taken, the restraining structure 7 reinforced by the three pillars generates a lateral supporting force, so that the rotating cover only has a vertical translational movement along the inner wall 23 of the container and a rotational movement centered on the axis 8, thereby ensuring that it does not Occurrence or tilting causes the paste 6 to be extruded from the edge of the cover.

Embodiment 3:

As shown in FIGS. 34-39, the paste taking package of the present embodiment is different from that of the first embodiment in that the restricting structure 7 of the present embodiment extends downward in the vertical direction at the outer edge of the access cover 3, so that the rotating cover is provided. The cross-sectional outer contour of the three-dimensional shape is "Π", and the restricting structure 7 of the present example is realized by the intermittent hard skeleton 9, the soft elastic body 13, and the intermittent rigid skeleton 9' is an elastic structure. Popped to the outside and wrapped by a continuous thinner soft elastomer 13. The advantage of this arrangement is that the skeleton is a hard material, so that the restriction structure 7 can maintain its basic function, and the rigid skeleton 9' has a certain elasticity, can be deformed, and can better adapt to the slope of the inner wall 23 of the container. The change, while the thinner soft elastomer 13 ensures the sealing of the access cover 3.

And the protective cover 10 is not a disk shape covering the entire upper surface 31 of the access cover, but only covers the access opening 34 and the soft sheet-like body around the periphery thereof, and one end is fixed to the upper surface of the access cover 3, and the other end is For the free end. The protective cover 10 in this embodiment may also be disposed such that one end is fixed to the lower surface 32 of the second opening side 36 of the access cover 3, and the other end is cantilevered to the first opening edge 35 to form a cantilever protection. Slice 17. Both of these settings can achieve the same effect as in the first embodiment.

Embodiment 4:

As shown in FIGS. 40-45, the paste taking package of the present embodiment is different from the previous three embodiments in that the cover 3 has no shovel 4 structure and is directly passed through the lower press cover 3 . The paste body 6 is taken, and the restricting structure 7 of the present example extends upward in the vertical direction on the outer edge of the take-up cover 3, so that the outer cross-section of the take-up cover 3 has a "U" shape; and the cover 3 is taken The ridge gradually protrudes from the periphery toward the center to press the paste 6 toward the access opening 34 in the middle of the take-up cover 3; the restricting structure 7 of this example is composed of a hard skeleton 9 and a thin soft elastic body 13.

After the take-up cover 3 is loaded into the container 2, the restraining structure 7 generates a lateral supporting force, so that the access cover 3 only moves up and down along the inner wall 23 of the container. When the paste body 6 is taken, the cover 3 is pressed down, and the cover is taken. 3 is smoothly lowered, and the paste 6 is extruded from the access opening 34 in the middle of the take-up cover 3, and the cantilever-shaped protective sheet 17 is lifted up and enters the upper cover surface 31 for the user's finger 100 to be removed. While the paste 6 is being applied, the cantilever-shaped protective sheet 17 is pressed back to re-cover the access opening 34 as shown in Figs. 44 and 45.

The paste take-up package of the present invention is suitable for use in a paste package such as a cosmetic, a skin care product, an ointment, an emulsion or a creamy food.

The above is a further detailed description of the present invention in connection with the specific embodiments, and it is not intended that the specific embodiments of the invention are limited to the description. It will be apparent to those skilled in the art that the present invention may be made without departing from the spirit and scope of the invention.
