Abstract
Description
Technical Field
[0001] This disclosure relates to medical lubricant bottles, and more particularly to a medical lubricant bottle that can be integrally manufactured using a blow-fill-seal process. Background Technology
[0002] Medical lubricants are widely used in many medical settings, including clinical medicine. Furthermore, the user of a medical lubricant can be a healthcare professional, a patient, or a family member.
[0003] A typical type of existing medical lubricant container is a small bag filled with lubricant. Although it is inexpensive and can be dispensed in small doses, it generally requires two hands to operate and is prone to uneven application or excessive lubricant squeezed out at one time. In addition, the tear-opening type of the bag may result in an opening that is too large. Lubricant bags with separate cap openings cannot be manufactured as a single piece and require blow molding and molding to form separate bag bodies and caps.
[0004] Other typical types of existing medical lubricants are bottles or syringes that also use a cap-type opening. However, the containers for these two types of medical lubricants are generally not manufactured in one piece, and in actual use, there is often a risk of accidental or unintentional opening of the opening or squeezing, which could cause the lubricant to leak out.
[0005] Therefore, there is an urgent need to provide a new medical lubricant bottle to at least partially alleviate or resolve the aforementioned problems and defects of existing solutions. Utility Model Content
[0006] One object of this disclosure is to propose a new medical lubricant bottle in order to at least alleviate or eliminate at least some of the defects of existing medical lubricant containers as described above.
[0007] This disclosure provides a medical lubricant bottle, characterized in that the medical lubricant bottle comprises:
[0008] A flexible bottle body, the bottle body being constructed to be able to stretch and extend in the longitudinal direction;
[0009] The upper part of the bottle protrudes from the top surface of the main body of the bottle and has an opening;
[0010] The cap portion has a door-shaped outer portion and a connecting portion, the connecting portion connecting the inner edge of the outer portion of the cap portion to the outer edge of the upper part of the bottle, and is configured to cover and close the opening;
[0011] The outer portion of the gate-shaped cover and the connecting portion are both sheet-like, and the thickness of the outer portion of the gate-shaped cover is more than three times the thickness of the connecting portion.
[0012] Therefore, the sheet-like and significantly thin connecting portion in the cap body constitutes a structurally weak part. During use, by twisting the cap body, this structurally weak part will break, exposing the opening at the top of the bottle, thus opening it. This achieves a medical lubricant bottle that is particularly suitable for twist-opening, and the design can be manufactured using a one-piece molding process.
[0013] According to some embodiments of this disclosure, the outer portion of the gate-shaped cap includes a crossbeam positioned above the opening and two side wings positioned on opposite sides of the upper part of the bottle and connected to each other via the crossbeam.
[0014] According to some embodiments of this disclosure, the inner edge of the outer portion of the gate-shaped cover and the connecting portion are in a zigzag shape that is consistent with each other, and the connecting portion also has a linear weak portion extending along the direction of the zigzag shape.
[0015] According to some embodiments of this disclosure, the thickness of the linear weak portion does not exceed half the thickness of the connecting portion.
[0016] According to some embodiments of this disclosure, the upper part of the bottle has a base portion and a dome with the opening, the base portion being generally truncated cone-shaped and gradually tapering upwards, and the dome being located on the base portion.
[0017] According to some embodiments of this disclosure, the linear fragile portion consists of two linear fragile portions located on opposite sides of the upper part of the bottle, the two linear fragile portions being separated by the dome and discontinuous from each other.
[0018] According to the above-described embodiment, this medical lubricant bottle is particularly suitable for a twist-off opening method, where the twisting action requires only a small force to open the cap. In contrast, an action that involves simply breaking or snapping the cap without rotating it around the longitudinal central axis of the medical lubricant bottle requires significantly greater external force. Therefore, this provides a solution that reduces the risk of unintentional, accidental, or undesirable breakage of the cap, thus preventing the lubricant bottle from opening accidentally. Furthermore, this design retains the structural advantage of being easily integrally manufactured using a blow-fill-seal (BFS) process.
[0019] According to some embodiments of this disclosure, the portion of the two linear weak sections furthest from the longitudinal central axis of the medical lubricant bottle extends obliquely from the inside out at a downward angle.
[0020] According to the above embodiment, the downward tilt angle at both ends of the linear weak portion makes the medical lubricant bottle particularly suitable for a twist-off opening operation.
[0021] According to some embodiments of this disclosure, the downward tilt angle is between 10° and 45°.
[0022] According to some embodiments of this disclosure, the crossbeam portion has protrusions at the connection points with the two side wings, and the two protrusions are arranged symmetrically with respect to the longitudinal central axis of the medical lubricant bottle.
[0023] These two protrusions facilitate easy hand-held opening of the lid.
[0024] According to some embodiments of this disclosure, the bottle body is accordion-shaped, and the medical lubricant bottle is made of polyethylene material and integrally formed using a blow-fill-seal process.
[0025] Blow-fill-seal (BFS) is a manufacturing process that integrates container forming, solution filling, and container sealing on a single machine. It offers advantages such as lower particulate risk, better aseptic stability, and lower risk of cross-contamination. Because BFS utilizes an integrated sealing / capping process, it is particularly suitable for the overall structural design of the medical lubricant bottles described in this disclosure. This ensures the aseptic properties of the medical lubricant bottles while achieving a relatively efficient and low-cost manufacturing process.
[0026] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present disclosure.
[0027] The positive and progressive effects of this disclosure are as follows:
[0028] The medical lubricant bottle according to this disclosure is designed to be easily opened by the user by twisting to facilitate the use of the lubricant contained in the bottle. Attached Figure Description

[0046] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The following description is exemplary and not intended to limit the present invention. Any other similar situations also fall within the protection scope of the present invention.
[0047] In the following detailed description, directional terms such as "left," "right," "up," "down," "front," and "back" are used with reference to the directions described in the accompanying drawings. Components of embodiments of this invention can be positioned in a variety of different orientations; the directional terms are for illustrative purposes and not restrictive.
[0048] From the foregoing description and the following more detailed exemplary description and drawings of a medical lubricant bottle according to a preferred embodiment of the present disclosure, those skilled in the art will understand that the design of the medical lubricant bottle according to the preferred embodiment of the present disclosure has many advantages, such as being particularly convenient for the user to open the opening by twisting to use the lubricant contained in the bottle, preventing the opening from being opened unintentionally or undesirably to avoid misuse of the lubricant, using relatively little material overall and being easy to manufacture with high efficiency, etc.
[0049] Figure 1-4 A medical lubricant bottle according to a preferred embodiment of the present disclosure is schematically shown. Reference is made to these figures, especially... Figure 1 and Figure 2 As shown, the medical lubricant bottle includes:
[0050] The flexible bottle body 1 is constructed to be able to stretch and extend in the longitudinal direction;
[0051] The upper part 2 of the bottle protrudes from the top surface of the main body 1 of the bottle and has an opening 211;
[0052] The cap body 3 has a door-shaped outer part and a connecting part 33. The connecting part 33 connects the inner edge 34 of the outer part of the cap body to the outer edge of the upper part 2 of the bottle and is configured to cover and close the opening 211.
[0053] The outer part of the gate-shaped cover (mainly composed of the crossbeam 32 and two side wings 31 described below) and the connecting part 33 are both sheet-like, and the thickness of the outer part of the gate-shaped cover is more than three times the thickness of the connecting part 33.
[0054] More specifically, the outer part of the door-shaped cap includes a crossbeam 32 positioned above the opening 211 and two side wings 31 positioned on opposite sides of the upper part 2 of the bottle and connected to each other via the crossbeam 32.
[0055] refer to Figure 1-2 As shown, the crossbeam 32 of the outer part of this door-shaped cover provides the cover itself with a certain structural strength or rigidity, while the two side wings 31 constitute the object or point of application of rotational / twisting force by the user to a certain extent, so that the user can easily apply this rotational force through the two side wings 31.
[0056] According to some preferred embodiments of the present disclosure, the inner edge 34 of the outer portion of the cover, which is shaped like a door, and the connecting portion 33 are in a zigzag shape that are consistent with each other. The connecting portion 33 also has a linear weak portion 331 extending in the direction of the zigzag shape.
[0057] The linear fragile part 331 extending along the direction of the zigzag shape further facilitates the user to twist the cap part and break it from the bottle by applying a rotational / twisting external force, thereby opening the opening 211.
[0058] More preferably, the thickness of the linear vulnerable portion 331 does not exceed half the thickness of the connecting portion 33. Thus, the thickness of the linear vulnerable portion 331 is significantly thinner relative to the crossbeam portion 32 and the side wing portion 31 of the outer portion of the cover, providing a structural vulnerable portion that is cost-effective to produce.
[0059] According to some preferred embodiments of the present disclosure, the upper part 2 of the bottle has a base part 22 and a dome 21 with an opening 211. The base part 22 is generally in the shape of a truncated cone that gradually narrows upwards, and the dome 21 is located on the base part 22.
[0060] More preferably, the linear fragile portion 331 is composed of two linear fragile portions 331 located on opposite sides of the upper part 2 of the bottle, and the two linear fragile portions 331 are separated by a dome and are discontinuous with each other.
[0061] According to the further preferred embodiment described above, this medical lubricant bottle is particularly suitable for a twist-off opening method, where the twisting action requires only a small force to open the cap. In contrast, an action that involves breaking or snapping the cap without rotating it around the longitudinal central axis of the medical lubricant bottle requires significantly greater external force. Therefore, this provides a solution that reduces the risk of unintentional, accidental, or undesirable breakage of the cap, thus preventing the lubricant bottle from opening accidentally. Furthermore, this design retains the structural advantage of being easily integrally manufactured using a blow-fill-seal process.
[0062] More specifically, it is the discontinuous section between the two linear weak parts 331 separated by the dome that enhances the design's ability to resist ordinary (intentional or accidental) breakage or snapping of the cover, while the action of twisting open still requires only a small force to unscrew the cover.
[0063] Based on this, further refer to the appendix Figure 1 and 2 According to some further preferred embodiments, the portion of the two linear weak portions 331 furthest from the longitudinal central axis of the medical lubricant bottle extends obliquely from the inside out at a downward angle. Furthermore, this downward angle is preferably between 10° and 45°.
[0064] In this preferred embodiment, the downward angle at both ends of the linear vulnerable portion 331 makes the medical lubricant bottle particularly suitable for a twist-off opening operation. This is because the shear force at both ends of the linear vulnerable portion 331, which initiates tearing of the linear vulnerable portion 331, is crucial for the desired twist-off opening operation. The downward angle further amplifies the shear force at the ends of the linear vulnerable portion 331 by applying a tilted motion, thus further strengthening the tearing effect. Furthermore, this downward angle also makes the linear vulnerable portion 331 relatively less susceptible to damage from unintended breakage or snapping of the cap, enhancing its resistance to ordinary (intentional or accidental) breakage or snapping of the cap.
[0065] According to some preferred embodiments of this disclosure, the crossbeam 32 has protrusions 321 at the connection points with the two side wings 31, and the two protrusions 321 are symmetrically arranged with respect to the longitudinal central axis of the medical lubricant bottle. This design further facilitates the hand-held rotation / twisting operation for opening the cap.
[0066] According to some preferred embodiments of this disclosure, as shown in the appendix Figure 1-3 As shown, the main body of the bottle 1 is accordion-shaped, and the medical lubricant bottle is made of polyethylene material and is integrally processed using a blow-fill-seal process.
[0067] The application of the blow-fill-seal integrated process can achieve advantages such as lower particulate risk, good aseptic stability, and low cross-contamination probability. Since the blow-fill-seal integrated process adopts an integral sealing / welding cap process, it is particularly suitable for the overall structural design of the medical lubricant bottle described in this disclosure, which not only ensures the aseptic characteristics of the medical lubricant bottle, but also achieves a relatively efficient and low-cost manufacturing process.
[0068] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
