Abstract
Description
Technology Field
[0001] The present invention relates to a locking and stroke-adjustable pump container, and,
[0002] More specifically, the invention relates to a pump container that accommodates a pumping body coupled to the upper part of a nozzle button and introduces a locking drum that is externally fitted into an inner cap coupled to the body and guided for lifting and lowering, and allows the contents to be pumped and discharged by contacting the lower surface of the nozzle button at the top dead center of the locking drum, which rotates easily and conveniently, and by unlocking it at the bottom dead center. Additionally, by forming a retention section in the middle of the rail slit of the locking drum, when the locking drum is located in this retention section, the nozzle button is caught before the bottom dead center, thereby reducing the discharge amount of contents and enabling stroke control. Background Technology
[0003] Pump containers, which are widely used for holding shampoos, lotions, etc., incorporate a locking ring or introduce an internal locking structure to prevent the nozzle button from being pressed during distribution and transportation.
[0004] For example, there is Patent Registration No. 10-1950808 (February 15, 2019) [Pump Dispenser],
[0005] This registered patent is capable of improving storage safety by structurally blocking the movement of high-viscosity liquids, such as toothpaste, when storing them in a container.
[0006] It includes a cap portion coupled to a container portion; a housing portion located inside the cap portion and forming a conduit that guides contents stored inside the container portion toward the outside of the container portion; a shaft portion inserted into the housing portion and moving up and down; a head portion coupled to one side of the shaft portion and having a passage for discharging contents; a stem portion connected to the other side of the shaft portion and having a passage for contents to flow into the inside of the shaft portion; and a valve portion installed in a shape penetrating the stem portion and opening and closing the passage for the contents in conjunction with the up and down movement of the stem portion.
[0007] Also, among the specifications of this registered patent
[0008] “
[0031] A threaded locking screw portion (52) is provided on the lower side of the head portion (50). Since the locking screw portion (52) is fastened to a thread provided on the inner side of the cover (26), it restricts the upward movement of the head portion (50). Therefore, when it is necessary to store the pump dispenser (1), the locking screw portion (52) of the head portion (50) is fastened to a thread provided on the inner side of the locking retaining portion (25), thereby restricting the movement of the head portion (50) and preventing the operation of the contents being discharged to the outside through the head portion (50).”
[0009] As described above, a typical structure is presented in which the male screw of the discharge head (nozzle button) and the female screw of the upper part of the inner cap are fastened together to lock the head.
[0010] However, products employing this patent and similar structures require rotating while pressing the nozzle button to tighten the screw for travel, which can cause unnecessary discharge of contents. Furthermore, if the lock fails even once, the amount of discharge increases, and the contents, such as lotion, get on tables, hands, and clothing, causing the inconvenience of having to clean up afterwards. The problem to be solved
[0011] Accordingly, the present invention aims to provide a pump container capable of pumping out contents by rotating a locking drum located on the lower part of the nozzle button and the outer circumference of the cap so that, as the nozzle button is lifted, the lower part of the nozzle button and the locking drum come into contact at the top dead center to lock the state, and at the bottom dead center, the locking drum becomes unlocked.
[0012] The present invention aims to provide a pump container capable of stroke control by having a guide projection of an inner cap coupled to a rail slit formed in a guide cap of a locking drum composed of a combination of an outer cap and a guide cap, and a retention portion formed on an inclined third rail connecting a horizontal first and second rails for top dead center and bottom dead center, so that when the guide projection is positioned in the retention portion, the nozzle button is caught before the bottom dead center, thereby reducing the discharge amount of contents.
[0013] Furthermore, the present invention aims to provide a pump container in which a tension slit is formed on the upper or lower part of the rail slit, or on the upper and lower parts, to ensure smooth lifting of the locking drum.
[0014] In addition, the present invention aims to provide a pump container in which the frame between the tension slit and the third rail has a relatively thin, thin section in the retention section. means of solving the problem
[0015] To achieve the above objectives, the locking and stroke-adjustable pump container according to the present invention
[0016] A body having a snout and a receiving portion;
[0017] Nozzle button for discharging contents;
[0018] An inner cap to which the above-mentioned nozzle button is coupled and which is coupled to the spout; and
[0019] A locking drum that is externally fitted into the inner cap and guided to move up and down according to rotation; comprising
[0020] This locking drum is characterized by being in a locked state by contacting the lower surface of the nozzle button at the top dead center and being in an unlocked state at the bottom dead center.
[0021] Also, in the locking and stroke-adjustable pump container according to the present invention
[0022] The above nozzle button is coupled to a pumping body coupled to the above inner cap, and
[0023] The above-mentioned locking drum is composed of a combination of an outer cap and a guide cap, and
[0024] A rail slit is formed in the above guide cap, and this rail slit is coupled with a guide projection of the inner cap, and
[0025] The rail slit of the above guide cap is composed of horizontal first and second rails for top dead center and bottom dead center, and an inclined third rail connecting them.
[0026] A retention section is formed in the third rail above, allowing for adjustment of the lifting stroke of the nozzle button, and
[0027] A tension slit is formed on the upper or lower part, or on the upper and lower parts, of the above rail slit, and
[0028] It is preferable that the frame between the above tension slit and the third rail has a relatively thin section in the retention section. Effects of the invention
[0029] The locking and stroke-adjustable pump container according to the present invention enables the contents to be pumped out by rotating a locking drum located on the lower part of the nozzle button and the outer circumference of the cap so that, upon lifting, the lower surface of the nozzle button and the locking drum come into contact at the top dead center and the contents become unlocked at the bottom dead center. Furthermore, a guide projection of the inner cap is coupled to a rail slit formed in the guide cap of the locking drum, which is composed of a combination of an outer cap and a guide cap. A retention section is formed on an inclined third rail connecting the horizontal first and second rails for the top and bottom dead centers. When the guide projection is positioned in this retention section, the nozzle button catches before the bottom dead center, thereby reducing the amount of contents discharged and enabling stroke adjustment. Moreover, a tension slit is formed on the upper or lower part, or on both the upper and lower sides, of the rail slit to ensure smooth lifting of the locking drum. Consequently, through the intuitive and easy-to-operate rotational lifting of the locking drum, locking can be performed without operating the nozzle button when necessary for travel or other purposes after initial opening, and when precise small-quantity discharge is desired, the retention section in the middle of the rail slit The amount of contents pumped can be controlled by adjusting the stroke of the nozzle button so that the guide projection of the inner cap is positioned.

Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.
[0037] The terms "~1~," "~2~," etc., described in this specification are used merely to distinguish different components, and are not bound by superiority or order of manufacture; furthermore, the names may not match those in the detailed description of the invention and the claims.
[0039] For convenience in describing the locking and stroke-adjustable pump container (A) according to the present invention, if a non-strict approximate directional reference is specified with reference to FIG. 1 [B],
[0040] The description is divided into top, bottom, left, and right as they appear in the city, and unless otherwise mentioned in the descriptions related to other drawings or in the claims, the description is made in accordance with this standard.
[0041] First, as can be seen in the assembled perspective view of FIG. 1 [A], the assembled cross-sectional view of FIG. 1 [B], and the exploded perspective view of FIG. 2,
[0042] A locking and stroke-adjustable pump container (A) according to the present invention comprises a body (10) having a spout (13) and a receiving portion (11), a nozzle button (20) for discharging contents, an inner cap (30) to which the nozzle button is coupled and which is (screwed) coupled to the spout (13), and a locking drum (40) that is fitted onto the inner cap and guided to move up and down according to rotation.
[0043] Also, the nozzle button (20) is coupled with a conventional pumping body (50) coupled to the inner cap (30).
[0044] The above-mentioned locking drum (40) is composed of a combination of an outer cap (41) and a guide cap (43),
[0045] The structure is such that two connecting protrusions (41a) on the inner upper side of the outer cap (41) are connected to two connecting grooves (43a) on the upper side of the guide cap, and
[0046] In addition to the interference fit method of this coupling groove and coupling projection, the tolerance between the inner diameter of the outer cap and the outer diameter of the guide cap can be minimized to enable interference fit coupling, and if necessary, the outer cap and the guide cap can be joined using an adhesive.
[0047] A rail slit (S) is formed in the guide cap (43), and the rail slit (S) is coupled with the guide projection (31) of the inner cap (30).
[0048] The rail slit (S) of the guide cap (43) consists of horizontal first and second rails (s1, s2) for top dead center and bottom dead center, and an inclined third rail (s3) connecting them.
[0049] Furthermore, a retention section (G) is formed on the third rail (s3), and when the locking drum (40) is rotated and adjusted so that the guide projection (31) is positioned in this retention section, the nozzle button is caught before the bottom dead center, thereby reducing the discharge amount of contents and allowing for stroke adjustment. The position and number of this retention section can be selected as needed.
[0050] As shown in the state of Fig. 1 [B], the locking drum (40) is in a locked state by contacting the lower surface of the nozzle button (20) at the top dead center, and is in an unlocked state at the bottom dead center, allowing for the lowest descent, i.e., maximum stroke of the nozzle button (20).
[0051] At the top dead center, the shoulder (41b) of the upper part of the outer cap (41) of the locking drum (40) is inserted into the lower skirt of the nozzle button (20), enabling stable locking of the nozzle button.
[0052] In addition, a tension slit (T) is formed on the upper or lower part, or on the upper and lower parts of the rail slit (S), and in the drawing, tension slits (T2) (T1) are formed on both the upper and lower parts.
[0053] As can be seen in the front view of the rail slit (S) within the left middle dashed line block of FIG. 2,
[0054] First and second protrusions (p1, p2) are formed on each of the horizontal first and second rails (s1, s2) for stable retention of the position-adjusted guide projection (31), and
[0055] In addition, a ledge is formed in the retention section (G) of the inclined third rail (s3) to ensure stable retention of the guide projection (31). In this retention section, considering the characteristics of the inclined third rail, a third ledge (p3) protruding from the lower part of the retention section in the form of a recess, and fourth and fifth ledges (p4, p5) formed above and below the upper part of the retention section are formed.
[0056] Also, the shape of the lower tension slit (T1) (T2) has upper and lower inclined slits with the middle first and second horizontal sections (ℓ1,ℓ2) in between, and the lower end of the upper tension slit (T2) also has a third horizontal section (ℓ3).
[0057] The first and second horizontal sections (ℓ1,ℓ2) are configured so that when the guide projection (31) located in the retention section (G) is guided downward past the third projection (p3) and enters the second horizontal rail (s2) to be positioned at the bottom dead center according to the rotation of the locking drum (40) (a combination of the outer cap (41) and the guide cap (43)), or is guided upward past the fourth and fifth projections (p4,p5) and enters the first horizontal rail (s1) to be positioned at the top dead center, the frame at each projection (p3,p4,p5) position is easily deformed as it spreads apart.
[0058] In addition, the third horizontal section (ℓ3), formed at a position corresponding to the second horizontal rail (s2) unlike the first horizontal rail (s1), is designed to allow the guide projection (31) of the inner cap (30) to be easily assembled to the second horizontal rail (s2) during the initial assembly of the guide cap (43), thereby allowing the frame between the second horizontal rail (s2) and the third horizontal section (ℓ3) to be easily deformed, and also to allow the guide projection (31) to pass through the second horizontal rail (s2) when it meets the second projection (p2), by causing the second horizontal rail (s2) to spread apart and the third horizontal section (ℓ3) to contract. In this way, the lower and upper tension slits (T1) (T2) below and above the tension slit (T), that is, the rail slit (S), function to cause the first, third, and second horizontal rails (s1, s3, s2) to spread apart and move easily when the guide projection (31) in the synthetic resin inner cap (30) meets the first, fourth, fifth, third, and second protrusions (p1, p4, p5, p3, p2) of the first, third, and second horizontal rails (s1, s3, s2) of the rail slit (S) by pressing each protrusion towards the lower tension slit (T1) (T2), and after the guide projection passes each protrusion, the horizontal rails are elastically restored.
[0059] Meanwhile, the frame between the tension slit (T) and the third rail (s3) has a relatively thin section in the retention section (G).
[0060] Specifically, as can be seen in the front view of the rail slit (S) within the left middle dotted line block of FIG. 2, the frame between the retention portion (G) and the first horizontal portion (ℓ1) of the first tension slit (T1) has a first thin portion (t1) that is relatively thinner than other parts.
[0061] Also, as can be seen in the front view of the deformation of the rail slit (S) within the lower left dotted line block of FIG. 2,
[0062] It is desirable that the first and second tension grooves (g1, g2) are formed in the portion corresponding to the inclined portion of the lower upper tension slit (T1) (T2) so that the frame's wall is formed thinly in the portions of the fourth and fifth protrusions (p4, p5), thereby forming the second and third thin portions (t2, t3), so that when the guide projection (31) of the inner cap (30) meets the fourth and fifth protrusions (p4, p5), the fourth and fifth protrusions (p4, p5) open more easily downward and upward due to the second and third thin portions (t2, t3), and the portions of the first and second tension grooves (g1, g2) contract more easily, so that the guide projection (31) passes more easily through the portions of the fourth and fifth protrusions (p4, p5), thereby ensuring smoother lifting of the locking drum (40).
[0063] Furthermore, as the third horizontal section (ℓ3) is also modified to form an additional third tension groove (g3) at the bottom of the upper tension slit (T2), a fourth thin section (t4) is formed, and when the guide projection (31) is assembled to the second horizontal rail (s2), the third horizontal section (ℓ3) can be easily opened and joined at the fourth thin section (t4), thereby improving the ease of initial assembly.
[0064] In the above description, the usual known technology related to the pumping body of the pump container (A) has been omitted, but a person skilled in the art can easily guess, infer, and reproduce it.
[0065] Furthermore, although the present invention has been described above with reference to the attached drawings and has focused on a pump container having a specific shape and structure, the present invention is capable of various modifications, changes, and substitutions by those skilled in the art, and such modifications, changes, and substitutions should be interpreted as falling within the scope of protection of the present invention.
