Description

Technical Field

[0001] The present disclosure relates to airless containers, and more particularly to airless containers whose volume can be adjusted.

Background Art

[0002] Conventional containers for storing food and liquids have limited airtightness and preservation effects. When the amount of the contents does not completely fill the internal space of the container, a space is generated between the liquid level or the surface of the contents and the container opening, and air such as oxygen and water vapor that easily causes chemical reactions is trapped therein. It is only necessary to put a desiccant or an antioxidant to prevent deterioration.

[0003] When a better preservation effect is desired, it is necessary to use a vacuum container having an air extraction structure that can evacuate the air in the container and minimize the amount of air enclosed therein. However, this technique is relatively cumbersome to operate and requires an additional air extraction procedure. In the case of a liquid having a low boiling point and being easily vaporized, waste and component changes also occur. In addition, since there is an air extraction structure, the container is bulky and takes up space.

Embodiments for Carrying Out the Invention

[0018] In order to fully understand the object, features, and effects of the present invention, the present invention will be described in detail below in combination with the drawings attached to specific examples.

[0019] As used herein, the terms "one" or "a" are used to describe units, members, structures, devices, modules, systems, parts, or regions, etc. This is merely for convenience and to give a general meaning to the scope of the present invention. This description should be read as including one or at least one, and the singular includes the plural unless it is clear that it means otherwise.

[0020] As used herein, the terms "comprising", "including", "having", or any other variant forms thereof are not necessarily limited to only those components, and can also include other components not explicitly listed for such units, members, structures, devices, modules, systems, parts, or regions, or other inherent components.

[0021] In this specification, terms related to space such as "above ~", "on ~", "below ~", "under ~" are used to facilitate the description of the relationship of one element or feature portion to another (one or more) element or (one or more) feature portion. These terms related to space may be intended to include other different orientations in addition to the orientation of each element or feature portion depicted in the drawings. These elements or feature portions may be oriented in other ways (rotated by 90 degrees or other orientations), and in this case, the terms related to space used in this specification shall also be interpreted accordingly.

[0022] In this specification, these terms related to space include the presence or absence of the arrangement of another (one or more) element or (one or more) feature portion between these elements or feature portions. For example, when it is described in the description that the first member is formed above or on the second member, embodiments that form direct contact between the first member and the second member may be included, and embodiments in which additional members are formed between the first member and the second member so that the first member and the second member do not come into direct contact may also be included.

[0023] (First Embodiment) Referring to FIGS. 1 to 3, FIG. 1 is a three-dimensional schematic view of an airless container according to the first embodiment, FIG. 2 is a three-dimensional schematic view of the airless container in FIG. 1 viewed from another perspective, and FIG. 3 is a cross-sectional view showing the usage state of the airless container in FIG. 1.

[0024] The airless container 1 can be used to store liquids, pasty substances or other contents, and by adjusting so that the liquid level or the top surface of the contents is as close as possible to the top of the container, the air content in the container can be reduced as much as possible after the container is closed.

[0025] The airless container 1 includes a container body 100, a stop piston 200, a lid 300, a base portion 400, and at least one adjuster 500.

[0026] The container body 100 includes a body portion 110 having a container mouth portion 110A and a bottom opening portion 110B. The body portion 110 may have a tubular shape with openings at both ends as shown in the figure, but is not limited thereto. The body portion 110 may form a neck portion where the portion near the container mouth portion 110A gradually reduces in diameter. The container body 100 can be made of a glass material or a plastic material, and may also be made of other types of materials.

[0027] The stop piston 200 is movably provided within the container body 100, and divides the internal space of the container body 100 into a storage region R1 and an adjustment region R2 that are not in communication. The storage region R1 is located above the adjustment region R2. That is, the storage region R1 is located on the upper side having the container mouth portion 110A of the body portion 110, and the adjustment region R2 is located near the lower side having the bottom opening portion 110B of the body portion 110. The stop piston 200 functions as a support surface to enable the storage region R1 to be used for storing liquids, pasty substances, or other contents. The stop piston 200 is in close contact with the inner wall surface of the container body 100, preventing air and liquid from passing between the stop piston 200 and the container body 100. The stop piston 200 is movable relative to the container body 100 under sufficient pushing force (overcoming the frictional force between the stop piston 200 and the inner wall of the container body 100), and is fixed when the pushing force disappears.

[0028] The lid body 300 is placed over the body portion 110 to close the container mouth portion 110A so that the storage region R1 forms a sealed space, and is used to prevent external air or substances from entering the storage region R1 through the container mouth portion 110A. The connection between the lid body 300 and the body portion 110 can be a screw structure, a clamping structure, a snap-fit structure, etc., allowing the user to perform opening and closing operations at any time.

[0029] The base portion 400 is provided on the container body 100, located on one side of the adjustment region R2, and has a hole portion 410 with an internal thread 411. The hole portion 410 communicates with the adjustment region R2. In this embodiment, the base portion 400 is detachably assembled to the bottom of the container body 100, and the connection between the base portion 400 and the container body 100 can be a screw structure, a clamping structure, a snap-fit structure, etc., and the user can operate as needed to make it detachable. The above connection structure between the container body 100 and the base portion 400 can be arranged on the inner wall or the outer wall of the container body 100.

[0030] The adjuster 500 includes a frustum portion 530 and an external thread portion 520, has a top base portion 510 at the top of the adjuster 500, has a lower opening portion 500A at the bottom, and the area of the top base portion 510 is smaller than the opening area of the lower opening portion 500A. On the outer surface of the adjuster 500, there is an external thread portion 520 corresponding to the internal thread 411 of the hole portion 410 of the base portion 400. The adjuster 500 is screwed into the hole portion 410 of the base portion 400 and is used to extend into the adjustment region R2 to push the stop piston 200. The top base portion 510 is a flat surface and is used to abut against the bottom of the stop piston 200 to apply a pushing force.

[0031] As shown in FIG. 3, when the airless container is in use, the adjuster 500 is rotated by the user and can be rotated within the hole portion 410, and the adjuster 500 can be screwed in or out by the screw structure. When it is necessary for the user to adjust the position of the stop piston 200 so that the liquid level of the stored content approaches the container opening 110A, the adjuster 500 is screwed into the hole portion 410 until the stop piston 200 reaches the desired position, protrudes into the adjustment region R2, and abuts against the bottom of the stop piston 200.

[0032] In this embodiment, the hole portion 410 is arranged at the central portion of the base portion 400, and the adjuster 500 is positioned at the central portion corresponding to the stop piston 200 through the hole portion 410, so that the force received by the stop piston 200 is distributed at the central portion.

[0033] In this embodiment, the height of the adjuster 500 is designed based on the required stroke length of the stop piston 200. The adjuster 500 can be housed in the hole 410 when not in use to prevent loss. Of course, the adjuster 500 can also be separated and stored elsewhere.

[0034] As an example, in the adjuster 500, the height of the male screw portion 520 occupies one-third of the height of each adjuster 500, and the height of the frustum portion 530 occupies two-thirds of the height of each adjuster 500. In one example, the outer diameter of the portion in the male screw portion 520 of the adjuster 500 is uniform. Due to the configuration of the screw portion, the user can finely adjust the height extending into the adjustment region R2 of the adjuster 500 by turning the adjuster 500, so as to finely adjust the position of the stop piston 200.

[0035] (Second Embodiment) Referring to FIGS. 4 to 7, FIG. 4 is a three-dimensional schematic view of the airless container according to the second embodiment, FIG. 5 is a three-dimensional schematic view of the airless container in FIG. 4 viewed from another perspective, FIG. 6 is a cross-sectional view of the airless container in FIG. 4, and FIG. 7 is a cross-sectional view showing the usage state of the airless container in FIG. 4.

[0036] In this embodiment, there may be a plurality of adjusters 500. According to the required stroke for the stop piston 200 to be pushed forward, a plurality of adjusters 500 are stacked (FIG. 7), screwed into the hole 410 of the base portion 400, extend into the adjustment region R2, and push the stop piston 200. That is, in the airless container 1' of this embodiment, the height of the container body 100 is designed to be relatively high. When the stop piston 200 needs to reach a position close to the container mouth portion 110A of the container body 100, it is necessary to stack more adjusters 500 to form a longer assembly. Since the adjuster 500 has a frustum shape with a narrow upper part and a wide lower part, stable vertical stacking can be formed.

[0037] In some usage conditions, it should be understood that it is not necessary to use all the adjusters 500 according to the volume of the contents to be accommodated. When removing or detaching the stacked adjusters 500, first separating the base portion 400 from the container body 100 allows the adjusters 500 to be quickly removed.

[0038] In this embodiment, the base portion 400 is provided with four storage holes 420, and each storage hole 420 has an internal thread 421 corresponding to the external thread portion 520 of each adjuster 500. As shown in FIG. 6, when not in use or in certain usage conditions, the adjuster 500 can be mounted in the hole portion 410 and / or the storage hole 420.

[0039] Although four storage holes 420 are shown in the figure, it is not limited thereto, and the number may be more or less. In FIG. 5, one adjuster 500 is mounted in the hole portion 410 and each storage hole 420, but it is not limited thereto. In a state where it is not in use, one or more adjusters 500 may be mounted as needed.

[0040] Referring to FIGS. 7 and 8 together, FIG. 8 is a three-dimensional schematic view of an adjuster according to some embodiments.

[0041] As shown in the figure, inside the adjuster 500, there is a frustum-shaped hole 540 communicating with the lower mouth portion 500A. The taper of the frustum-shaped hole 540 corresponds to the taper of the frustum portion 530, facilitating the vertical stacking of a plurality of adjusters 500 (FIG. 7). When a plurality of adjusters 500 are stacked on top of each other, the top base portion 510 of the lower adjuster 500 passes through the lower mouth portion 500A of the upper adjuster 500, and the frustum portion 530 of the lower adjuster 500 is partially or completely received in the frustum-shaped hole 540 of the lower adjuster 500.

[0042] (Third Embodiment) Referring to FIGS. 9 and 10, FIG. 9 is a three-dimensional schematic view of an airless container according to the third embodiment, and FIG. 10 is a cross-sectional view showing the usage state of the airless container of FIG. 9.

[0043] As shown in the figure, since the outer bottom of the base portion 400 has a flange 430, a recessed region R3 is formed at the bottom of the tubeless container 1". Depending on the adjustment of the position of the stop piston 200, the adjuster 500 may protrude from the base portion 400 in some usage scenarios. In the present embodiment, the tubeless container 1" is supported on a table or a flat surface via the flange 430, and the bottom surface having the hole portion 410 of the base portion 400 is separated from the table or the flat surface by a certain distance D (FIG. 10), so that the adjuster 500 protruding from the bottom surface of the base portion 400 does not affect the vertical placement of the tubeless container.

[0044] As an example, the distance D may be equal to or greater than one-third of the height of the adjuster 500. In this aspect, referring to FIG. 10, when the tubeless container 1" is provided with a plurality of adjusters 500, the unused adjusters 500 can be housed in the recessed region R3. Even if the adjuster 500 protrudes from the bottom surface of the base portion 400, it will not protrude from the bottom opening 110B and will not affect the vertical placement of the tubeless container 1".

[0045] As another example, the distance D is substantially equal to the height of the adjuster 500, and the height of the adjuster 500 may be equal to the entire length of the movable stroke of the stop piston 200 within the container body 100. In this aspect (not shown), only one adjuster 500 can be equipped on the tubeless container, and since the height of the adjuster 500 is sufficiently high, the stop piston 200 can be controlled to stop at any position during the movable stroke within the body portion. Therefore, there is no need to stack the adjusters 500, nor is it necessary to go through the operation process of separating the base portion 400 from the container body 100 to remove the adjuster 500.

[0046] (Fourth Embodiment) Referring to FIGS. 11 and 12 together, FIG. 11 is a three-dimensional schematic view of a tubeless container according to the fourth embodiment, and FIG. 12 is a cross-sectional view showing the usage state of the tubeless container of FIG. 11.

[0047] In this embodiment, the base portion 400 is removably assembled to the body portion 110 and is separated from the bottom opening 110B by a certain distance D' (FIG. 12). Thus, a recessed region R3' is defined by the bottom peripheral edge of the container body 100 that defines the bottom opening 110B and the base portion 400. The base portion 400 is assembled inside the container body 100 through the bottom opening 110B, and the connection between the base portion 400 and the container body 100 can be a screw structure, a clamping structure, etc., and the user can operate it as needed to make it detachable.

[0048] As an example, the distance D' may be equal to or greater than one-third of the height of the adjuster 500. In this aspect, referring to FIG. 12, when the airless container 1''' is provided with a plurality of adjusters 500, the unused adjusters 500 can be stored in the recessed region R3'. Even if the adjuster 500 protrudes from the bottom surface of the base portion 400, it will not protrude from the bottom opening 110B and will not affect the vertical placement of the airless container 1'''.

[0049] As another example, the distance D' is substantially equal to the height of the adjuster 500, and the height of the adjuster 500 may be equal to the total length of the movable stroke of the stop piston 200 within the body portion 110. In this aspect (not shown), only one adjuster 500 can be equipped on the airless container. Since the height of the adjuster 500 is sufficiently high, the stop piston 200 can be controlled to stop at any position within the movable stroke in the body portion. Therefore, there is no need to stack the adjusters 500, nor is it necessary to go through the operation process of separating the base portion 400 from the container body 100 to take out the adjuster 500.

[0050] As shown in the figure, the airless container 1''' of this embodiment is supported on a table or a plane by the bottom peripheral edge of the container body 100. The bottom surface having the hole portion 410 of the base portion 400 is separated from the table or the plane by a certain distance, so that the adjuster 500 that may protrude from the bottom surface of the base portion 400 can be accommodated in the recessed region R3', thus not affecting the vertical placement of the airless container 1'''.

[0051] The airless container according to the above-described embodiment of the present invention can adjust the space for liquids, pasty substances, or other contents accommodated in the container body by rotating the adjuster to adjust the stop piston stop position on the barrel portion, effectively discharge the air in the container body, reduce the influence of oxygen, moisture, and carbon dioxide in the air, maintain the quality during the storage period of the internal substance, help extend the storage period, and also prevent changes in the components of the content due to air bleeding. Thereby, the airless container according to the above-described embodiment of the present invention not only reduces the demand for desiccants and antioxidants when storing foods and substances, but also reduces the generation of plastic waste due to the reusability of the airless container, bringing a positive impact on environmental protection.

[0052] Although the present invention has disclosed the best embodiments above, as can be understood by those skilled in the art, this embodiment is only used to explain the present invention and should not be understood as limiting the scope of the present invention. It should be noted that all changes and substitutions having the same effect as this embodiment are included within the scope of the present invention. Therefore, the protection scope of the present invention shall be in accordance with the definition of the claims.
